Definitions
- the present invention relates to a broker according to the preamble of claim 1.
- the working device such as e.g. B. the drilling gear is dismantled together with the implement carriage for transport.
- implement slides have generally been attached to the feed slide with four bolts via side bolt mounts. The bolts are inserted during assembly after the mounting sockets on the slides have been positioned exactly one above the other.
- the leader with the attached feed carriage must be very precisely aligned with the implement carriage on the ground.
- the assembly of the implement carriage on the feed carriage is therefore complex, complicated and time-consuming.
- assembly and disassembly is a regularly recurring activity, this process should be carried out relatively easily and quickly under construction site conditions, if possible without additional aids.
- the object of the present invention is therefore to provide a leader in which the implement carriage can be mounted on the feed carriage more easily and quickly.
- first connecting elements are provided which, through a relative movement of the implement carriage and the feed carriage, establish a first connection between the implement carriage and the feed carriage, via which the implement carriage sits on the feed carriage.
- the implement carriage with the implement can first be placed on the feed carriage via a relative movement of the two carriages and thus prepositioned, without the need for precise alignment.
- the two carriages can then, if necessary, be positioned in an assembly position in order to be finally connected. This results in significantly faster and simplified assembly.
- the first connecting elements on the implement carriage and feed carriage are positioned in such a way that they can be pushed into one another in the direction in which they establish the first connection via the relative movement between the implement carriage and the feed carriage. Further positioning is then supported by the first connecting elements.
- the first connection takes place through a relative movement of the implement carriage and the feed carriage in the longitudinal direction of the leader, and in particular, when the leader is aligned essentially vertically, the movement of the feed carriage relative to the implement carriage takes place from bottom to top.
- the implement carriage sits on the feed carriage from above and is then held in this position by the first connecting elements.
- the first connection allows a certain movement of the implement carriage relative to the feed carriage in the longitudinal direction of the leader.
- this enables a relative movement of the first connecting elements against one another when the implement carriage is loaded by the implement, so that the carriages can be held here solely via a second connection, which enables a targeted introduction of force.
- the first connecting elements allow the feed carriage to move relative to the implement carriage from bottom to top until the implement carriage rests on the feed carriage.
- the implement carriage is fixed downwards in the vertical direction by the first connecting elements, so that it only needs to be aligned horizontally with respect to further connecting elements.
- the implement carriage is still fixed at the bottom relative to the feed carriage, but is still movable upwards.
- implement carriages and feed carriages have, in addition to the first connecting elements via which the first connection is made, second connecting elements for producing a second connection. If the implement carriage has been placed on the feed carriage via the first connecting elements and, if necessary, positioned in its assembly position, it can be finally connected to the feed carriage via the second connecting elements.
- this makes it possible to first push the implement carriage onto the feed carriage via the first connecting elements, and only then then align it into a mounting position so that the second connecting elements can be placed.
- the first connecting elements are arranged above the second connecting elements when the leader is aligned vertically.
- This has the advantage that when the implement carriage is placed on the feed carriage, the implement carriage hangs on the feed carriage by means of the first connecting elements, so that it is held in the correct position solely by gravity.
- this allows a particularly favorable force distribution, in which only the lower connecting elements transmit forces along the longitudinal direction of the leader.
- the first connecting elements fix the implement carriage on the feed carriage in a mounting position transverse to the longitudinal direction of the leader. If the leader is aligned vertically for assembly, the first connecting elements prevent the implement carriage from moving away from the feed carriage after the implement carriage has been placed on the feed carriage.
- the first connecting elements form an axis of rotation, so that the implement carriage can be folded towards the feed carriage.
- the second connecting elements therefore fix the implement carriage on the feed carriage at least in the longitudinal direction of the leader.
- This is the direction in which the z. B. forces occurring during drilling must be transferred from the implement carriage to the leader, so that the second connecting elements take over this force transmission.
- the first connecting elements allow the implement carriage to move in this direction, this has the advantage that the implement carriage is no longer mounted in an overdetermined manner in the longitudinal direction of the leader. This allows the power transmission from the implement to the leader to be precisely defined and there are no additional loads due to internal tension.
- the second connecting elements fix the implement carriage on the feed carriage in the longitudinal and transverse directions of the leader.
- the implement carriage is advantageously held on the feed carriage by the second connecting elements in such a way that only a rotational movement about a horizontal axis of rotation is possible.
- this rotation is prevented by the first connecting elements, which fix the implement carriage in a tangential direction with respect to this axis of rotation.
- the fact that the first connecting elements do not fix the implement carriage in the radial direction to this axis of rotation at least on one side results in the advantage of a storage already described above, which is not overdetermined in the vertical direction.
- the implement carriage can first be placed on the feed carriage in an angled position relative to the feed carriage through the first connecting elements, whereupon the feed carriage and the implement carriage can be pivoted towards each other.
- the first connecting elements are arranged in the upper area of the implement carriage and feed carriage, the implement carriage is automatically held in position by gravity. This is particularly advantageous if the second connecting elements are located below the first connecting elements.
- the second connecting elements are in their assembly position after being swiveled in.
- the first connecting elements must first be aligned with one another and pushed into one another, whereupon the feed carriage can be pivoted towards the implement carriage, whereby the second connecting elements are already in the assembly position, so that this connection can be easily established without further alignment.
- the leader according to the invention advantageously comprises a stop for the implement carriage placed on the feed carriage, which is designed in particular in such a way that the second connecting elements are in their assembly position when the implement carriage rests against the stop.
- This stop which is advantageously arranged on the feed carriage, enables the second connecting elements to be precisely positioned in their assembly position.
- the stop for the implement slide placed on the feed slide and/or its counter element is adjustable.
- the fine adjustment for positioning the second connecting elements can be carried out by adjusting the stop or the counter element.
- the first and/or the second connecting elements are arranged laterally on the implement carriage and on the feed carriage.
- the back of the feed carriage faces the leader and surrounds a guide on the leader with rear, laterally arranged guide elements, via which it is guided along the longitudinal direction of the leader.
- the front of the feed carriage represents a coupling level to the implement carriage.
- the lateral arrangement of the first and/or the second connecting elements results in a stable connection.
- first and/or the second connection each comprise two connection points.
- these can each be arranged so that they form an axis of rotation.
- the connecting elements are advantageously arranged on the right and left on the two sides of the implement carriage and the feed carriage. This results in a secure and easy-to-assemble connection.
- the second connecting elements can comprise connecting points arranged on the left or right of the carriage and consisting of conventional bolt receptacles assigned to one another in the form of bushings, each of which is connected by a bolt.
- first and/or the second connecting elements each have two bolts, which are arranged on the left and right on the implement carriage or on the feed carriage in such a way that the bolts are aligned coaxially with one another.
- the pairs of bolts of the first and second connecting elements thus define a common axis of rotation.
- the first connecting elements advantageously comprise a bolt receptacle which is open to one side along the longitudinal direction of the leader. This allows a bolt to be pushed into the bolt receptacle by moving the feed carriage relative to the implement carriage in the longitudinal direction of the leader.
- the bolt receptacle is open to one side transversely to the main direction of the bolt, so that the bolt can be inserted into the bolt receptacle transversely to its main direction.
- This makes it possible in a simple manner to first mount the bolts in the conventional receiving sockets of one carriage and then to insert the bolts transversely to their main direction via the open side of the bolt holder on the other carriage in order to place the implement carriage on the feed carriage .
- the bolt receptacle is open in the longitudinal direction of the leader. If the leader is positioned vertically, this means that the bolt receptacle is open either upwards or downwards, so that the bolt can be pushed into it either from below or from above, while the main direction of the bolt is oriented horizontally.
- the bolt receptacle advantageously has an opening which enlarges towards its open side, which facilitates the insertion of the bolt from this side. This means that precise positioning of the bolt on the bolt holder is not necessary, as the funnel-like opening guides the bolt.
- the bolt receptacle is advantageously arranged on the feed carriage and is open at the top.
- the bolt is thus fastened, in particular horizontally, to the implement carriage via a usual receiving bushing and is inserted from above into the bolt receptacle on the feed carriage.
- the implement carriage hangs from the bolts on the feed carriage and is held by the bolts resting in the bolt receptacle, which is open at the top.
- the bolt holder is arranged on the implement carriage and is open at the bottom.
- the bolts are therefore mounted on the feed carriage in normal receiving bushings, particularly horizontally, whereby the bolt holder, which is open towards the bottom, can be hung on the bolts on the implement carriage.
- the second connecting elements have two receiving bushings, which are bolted together.
- the second connection through the second connecting elements is thus carried out as in the prior art, but the pre-positioning by the first connecting elements no longer causes any positioning problems and the bolts can be set without any problems.
- the leader according to the invention advantageously has a multi-coupling on the feed carriage for hydraulic and / or electrical coupling of the working device.
- a multi-coupling in turn makes it easier to connect the implement to the leader, with the multi-coupling advantageously comprising all hydraulic and/or electrical connecting lines for the implement.
- the present invention also includes a corresponding feed carriage according to claim 18 and a corresponding implement carriage according to claim 21, via which the simplified assembly according to the invention is possible.
- the present invention includes a feed carriage according to claim 18 for a leader according to claim 1, which has upper and lower connecting elements for connection to a work implement carriage, the upper connecting elements comprising bolt receptacles which are open towards the top.
- the implement carriage can therefore have the usual receptacle bushings for the bolts and is placed on the feed carriage with the bolts already mounted, with the bolts engaging in the bolt receptacles that are open at the top.
- the bolt receptacles are arranged laterally.
- the bolt receptacles advantageously have an opening that enlarges towards the top, which makes it easier to insert the corresponding bolt on the implement carriage.
- the implement carriage and the feed carriage only have to be positioned approximately against each other, since the bolt on the implement carriage automatically e.g. B. slides into the bolt holder when the feed carriage is raised.
- a multi-coupling for hydraulic and/or electrical coupling of the working device is provided on the feed carriage, which simplifies the hydraulic and/or electrical coupling.
- the feed carriage according to the invention can advantageously also have all of the other features described above with regard to the leader.
- the lower connecting elements can have receiving bushings for bolts, via which the feed carriage can be bolted to the implement carriage in its lower region.
- the bolt receptacles which are open to one side, can also be arranged on the implement carriage.
- the present invention therefore further comprises an implement carriage according to claim 21 for a leader according to claim 1, which has upper and lower connecting elements for connection to a feed carriage according to claim 18, the upper connecting elements comprising bolt receptacles open towards the bottom.
- the bolts attached to the feed carriage can be inserted from below into the bolt receptacles, which are open at the bottom.
- the bolt receptacles are advantageously arranged laterally.
- the bolt receptacles advantageously have an opening that enlarges towards the bottom, which makes it easier to insert the corresponding bolt on the feed carriage.
- the present invention further includes a leader according to claim 23 with an implement carriage according to claim 21 or a feed carriage according to claim 18 as described above. This obviously results in the same advantages as described above.
- the present invention also includes an implement according to claim 24 with an implement carriage according to claim 21 as described above.
- the present invention further comprises a method according to claim 25 for mounting an implement carriage according to claim 21 on the feed carriage according to claim 18 of a leader according to claim 1, comprising the steps: positioning first connecting elements on the implement carriage and on the feed carriage so that they lie opposite one another; Moving the feed carriage relative to the implement carriage by the leader kinematics until the implement carriage rests on the feed carriage through the first connecting elements.
- the method according to the invention results in the same advantages already described with regard to the leader, in particular a considerably simplified assembly of the implement carriage on the feed carriage, since the first connecting elements can be guided into one another by moving the feed carriage relative to the implement carriage, which significantly reduces the requirements for previous positioning .
- the leader is first tilted forward so that the first connecting elements can be pushed into one another without the work equipment carriage getting in the way of the feed carriage.
- the feed carriage is moved upwards relative to the implement carriage by the leader kinematics. So you can e.g. B. Bolts can be pushed into a receptacle that is open at the bottom or, conversely, a receptacle that is open at the top can be pushed onto bolts from below. This makes assembly particularly simple, with the bolts advantageously being guided by a correspondingly widening opening.
- the implement carriage and the feed carriage are positioned relative to one another in an assembly position after the implement carriage has been placed.
- this positioning is guided by the first connection, for example by forming an axis of rotation about which the feed carriage and implement carriage can be pivoted towards one another.
- the positioning of the implement carriage relative to the feed carriage in a mounting position is advantageously carried out by raising the leader, which was previously inclined forward.
- the feed carriage is thus pivoted towards the implement carriage held by the first connecting elements due to gravity.
- the implement carriage and the feed carriage are advantageously connected in the assembly position by second connecting elements.
- the second connecting elements thus establish a secure connection between the implement carriage and the feed carriage without the need for complex and time-consuming positioning.
- FIG. 1 now shows an embodiment of the leader 2 according to the invention, which is articulated on a movable construction device 1, in this case a crawler crane.
- the leader 2 can be moved via various adjusting elements, and is shown here in a vertical position.
- the leader 2 has laterally arranged guides 7, which are surrounded by corresponding guide elements 17 on the feed carriage.
- the feed carriage is guided along the longitudinal axis of the leader 2 by the interaction of guide elements 17 and guide 7, whereby it can be moved via a cable feed system.
- the implement carriage 20, which carries the implement 30, is mounted on the feed carriage 10. Since the leader 2 is used here for drilling, the working device 30 is a drilling gear. In order to reduce the transport weight and the transport dimensions of the leader 2, the drilling gear 30 is often dismantled together with the drilling gear carriage 20 for transport from the feed carriage 10 and only assembled at the place of use, which is now considerably simplified by the present invention.
- FIG. 2a to 2c An exemplary embodiment of the feed carriage according to the invention, as used in the in Figure 1 shown embodiment of the leader according to the invention is used, is now in detail Figures 2a to 2c shown.
- the feed carriage 10 has the guide elements 17 already mentioned above, which surround the guide 7 on the leader 2.
- the guide elements 17 are arranged laterally on the back of the feed carriage 10, namely at the top and bottom.
- the feed carriage is guided on the leader 2 along its longitudinal axis via the guide elements 17.
- An upper roller 11 and an invisible lower roller are provided, which are mounted on axes 13 and 14 and over which the cable of the cable feed system runs.
- the feed carriage has upper bolt receptacles 15 and lower bolt receptacles 16, which are each arranged laterally on the left and right of the feed carriage.
- the two upper bolt receptacles 15 are a mirror image of one another with respect to the central longitudinal axis of the feed carriage, as are the two lower bolt receptacles 16.
- the lower bolt receptacle 16 is a receiving bushing, as is already known from the prior art. Here, bolts can be inserted into the receiving bushings 16 along their main direction in order to bolt the feed carriage to the implement carriage.
- the upper bolt receptacles 15, on the other hand, are not listed as bushings according to the invention, but are open at the top. They thus form a trough into which a bolt can be inserted from above, transversely to its main direction.
- the openings of the bolt receptacles 15 become wider towards the top, so that threading the bolts is made easier.
- the bolt receptacles 15 are therefore open upwards along the longitudinal direction of the feed carriage and thus of the leader 2, so that corresponding bolts on the implement carriage can be inserted into the bolt receptacles 15 by a relative movement from the feed carriage to the implement carriage, so that a first connection for pre-positioning is established .
- the implement carriage then sits over the bolts in the bolt receptacle 15, so that an axis of rotation is formed around which the carriages can be pivoted towards each other.
- the front side 18 of the feed carriage represents a coupling plane which faces the back of an implement carriage coupled to the feed carriage.
- FIG. 3a to 3c A work carriage 20 mounted on the feed carriage 10 is now shown, which carries the drilling drives 31.
- the implement carriage 20 has upper bolt receptacles 25 and lower bolt receptacles 26 in its side areas on the back, both of which are designed as receptacle bushings.
- the bolts 35 and 36 inserted into these receiving bushings 25 and 26 are aligned by the corresponding arrangement of the bushings 25 and 26 with their main direction transverse to the longitudinal direction of the leader so that their main axis runs in the coupling plane of the implement carriage and feed carriage.
- the two upper bushings 25, which are located in opposite side regions of the implement carriage 20, are aligned coaxially with one another, as are the two lower bushings 26, so that they form a common axis of rotation.
- the bolts 35 are already inserted into the upper bolt receptacles 25 on the implement carriage, or remain there anyway during disassembly.
- the implement carriage stands on the floor with the bolts 35 inserted.
- the The feed carriage is located at the bottom of the leader, which is tilted slightly forward with its upper area.
- the bolt receptacles 15 on the feed carriage 10 which are open at the top, can be positioned under the bolts 35 on the implement carriage 20.
- the two upper bolts 35 can now be threaded into the bolt receptacles 15.
- the opening that enlarges upwards and the fact that only two bolts have to be taken into account make the pre-positioning process much easier.
- the bolt receptacle 15 on the feed carriage which is open at the top, the receptacle bushing 25 on the implement carriage and the bolt 35, forms a first connection 5, which is produced by a movement of the feed carriage 10 relative to the implement carriage 20.
- the implement carriage 20 can thus be placed on the feed carriage without the need for precise positioning.
- the receiving trough of the bolt receptacle 15, which is open at the top, results in the first connection 5, in which the bolt 35 resting in the receiving trough fixes the implement carriage downwards and to the side, so that a corresponding axis of rotation results.
- the implement carriage and the feed carriage can then be pivoted towards each other about this axis of rotation, with the feed carriage arranged on the leader being moved via the leader kinematics during this relative movement of the feed carriage and the implement carriage.
- An adjustable stop is provided which stops the carriage in the assembly position of the second connecting elements, so that the bolts can be inserted without any effort to produce the second connection.
- the lower bolt receptacles 16 and 26 on the feed carriage 10 and implement carriage 20 together with the bolt 36 form the second connection, which fixes the implement carriage up and down and forwards and backwards relative to the feed carriage.
- the implement slide 20 is also secured laterally to the feed slide by the respective opposite bolts 35 and 36 with the bolt receptacles 15 and 16 pointing laterally outwards on the feed slide.
- a further advantage of the fastening solution according to the invention, in which the first connection 5 allows the implement carriage 20 to move upwards relative to the feed carriage 10, is that the implement carriage 20 is no longer overdetermined in the vertical direction. This allows the power transmission e.g. B. from the drill drive mounted on the implement carriage 20 to the leader in a precisely defined vertical direction via the second connections 6, so that there are no additional loads due to internal tensions.

Description
Die vorliegende Erfindung betrifft einen Mäkler nach dem Oberbegriff des Anspruchs 1.The present invention relates to a broker according to the preamble of claim 1.
Um das Transportgewicht und die Transportabmessungen des Mäklers zu verringern, wird häufig das Arbeitsgerät wie z. B. das Bohrgetriebe zusammen mit dem Arbeitsgeräteschlitten für den Transport demontiert. Bisher sind Arbeitsgeräteschlitten im Allgemeinen mit vier Bolzen am Vorschubschlitten über seitliche Bolzen-aufnahmen befestigt. Die Bolzen werden dabei bei der Montage gesteckt, nachdem die Aufnahmebuchsen bei-der Schlitten genau übereinander positioniert worden sind. Damit das Stecken der Bolzen ohne größeren Kraft-aufwand möglich ist, bedarf es einer sehr genauen Ausrichtung des Mäklers mit dem daran befestigten Vorschubschlitten an dem am Boden stehenden Arbeitsgeräteschlitten. Die Montage des Arbeitsgeräteschlittens am Vorschubschlitten ist daher aufwendig, kompliziert und zeitraubend. Da es sich bei der Montage und Demontage jedoch um eine regelmäßig wiederkehrende Tätigkeit handelt, sollte dieser Vorgang unter Baustellenbedingungen relativ einfach und schnell zu bewerkstelligen sein, wenn möglich ohne zusätzlich Hilfsmittel. Einen Mäkler mit Vorschubschlitten und Arbeitsschlitten zur Montage und Demontage eines Arbeitsgerätes zeigt
Erfindungsgemäß wird diese Aufgabe gemäß Anspruch 1 gelöst. Bei diesem Mäkler sind erfindungsgemäß erste Verbindungselemente vorgesehen, welche durch eine Relativbewegung von Arbeitsgeräteschlitten und Vorschubschlitten eine erste Verbindung von Arbeitsgeräteschlitten und Vorschubschlitten herstellen, über welche der Arbeitsgeräteschlitten auf dem Vorschubschlitten aufsitzt. Hierdurch kann der Arbeitsgeräteschlitten mit dem Arbeitsgerät zunächst über eine Relativbewegung der beiden Schlitten auf dem Vorschubschlitten aufgesetzt und so vorpositioniert werden, ohne dass hierfür eine exakte Ausrichtung nötig wäre. Daraufhin können die beiden Schlitten gegebenenfalls noch in einer Montageposition positioniert werden, um endgültig verbunden zu werden. So ergibt sich eine erheblich schnellere und vereinfachte Montage. Insbesondere muß so lediglich darauf geachtet werden, dass die ersten Verbindungselemente an Arbeitsgeräteschlitten und Vorschubschlitten so positioniert sind, dass sie in die Richtung, in welche sie über die Relativbewegung zwischen Arbeitsgeräteschlitten und Vorschubschlitten die erste Verbindung herstellen, ineinander geschoben werden können. Die weitere Positionierung wird dann bereits von den ersten Verbindungselementen unterstützt. Erfindungsgemäß erfolgt dabei die erste Verbindung durch eine Relativbewegung von Arbeitsgeräteschlitten und Vorschubschlitten in Längsrichtung des Mäklers, und insbesondere erfolgt bei einer im wesentlichen vertikalen Ausrichtung des Mäklers die Bewegung des Vorschubschlittens relativ zum Arbeitsgeräteschlitten von unten nach oben. Hierdurch sitzt der Arbeitsgeräteschlitten von oben auf dem Vorschubschlitten auf und wird dann in dieser Lage von den ersten Verbindungselementen gehalten.According to the invention, this object is achieved according to claim 1. In this leader, according to the invention, first connecting elements are provided which, through a relative movement of the implement carriage and the feed carriage, establish a first connection between the implement carriage and the feed carriage, via which the implement carriage sits on the feed carriage. As a result, the implement carriage with the implement can first be placed on the feed carriage via a relative movement of the two carriages and thus prepositioned, without the need for precise alignment. The two carriages can then, if necessary, be positioned in an assembly position in order to be finally connected. This results in significantly faster and simplified assembly. In particular, it is only necessary to ensure that the first connecting elements on the implement carriage and feed carriage are positioned in such a way that they can be pushed into one another in the direction in which they establish the first connection via the relative movement between the implement carriage and the feed carriage. Further positioning is then supported by the first connecting elements. According to the invention, the first connection takes place through a relative movement of the implement carriage and the feed carriage in the longitudinal direction of the leader, and in particular, when the leader is aligned essentially vertically, the movement of the feed carriage relative to the implement carriage takes place from bottom to top. As a result, the implement carriage sits on the feed carriage from above and is then held in this position by the first connecting elements.
Erfindungsgemäß erlaubt dabei die erste Verbindung eine gewisse Bewegung des Arbeitsgeräteschlittens relativ zum Vorschubschlitten in Längsrichtung des Mäklers. Neben dem einfachen Herstellen der ersten Verbindung durch Einschieben der ersten Verbindungselemente ineinander ermöglicht dies bei einer Belastung des Arbeitsgeräteschlittens durch das Arbeitsgerät eine Relativbewegung der ersten Verbindungselemente gegeneinander, so dass die Schlitten hier allein über eine zweite Verbindung gehalten werden können, was eine gezielte Krafteinleitung ermöglicht.According to the invention, the first connection allows a certain movement of the implement carriage relative to the feed carriage in the longitudinal direction of the leader. In addition to simply establishing the first connection by pushing the first connecting elements into one another, this enables a relative movement of the first connecting elements against one another when the implement carriage is loaded by the implement, so that the carriages can be held here solely via a second connection, which enables a targeted introduction of force.
Erfindungsgemäß erlauben die ersten Verbindungselemente bei einer vertikalen Ausrichtung des Mäklers die Bewegung des Vorschubschlittens relativ zum Arbeitsgeräteschlitten von unten nach oben, bis der Arbeitsgeräteschlitten auf dem Vorschubschlitten aufliegt. Hierdurch wird der Arbeitsgeräteschlitten durch die ersten Verbindungselemente in vertikaler Richtung nach unten hin fixiert, so dass er lediglich bezüglich weiterer Verbindungselemente gegebenenfalls noch horizontal ausgerichtet werden muß. In dieser Position ist der Arbeitsgeräteschlitten relativ zum Vorschubschlitten noch unten hin festgelegt, nach oben aber weiterhin beweglich.According to the invention, when the leader is aligned vertically, the first connecting elements allow the feed carriage to move relative to the implement carriage from bottom to top until the implement carriage rests on the feed carriage. As a result, the implement carriage is fixed downwards in the vertical direction by the first connecting elements, so that it only needs to be aligned horizontally with respect to further connecting elements. In this position, the implement carriage is still fixed at the bottom relative to the feed carriage, but is still movable upwards.
Erfindungsgemäß weisen erfindungsgemäß Arbeitsgeräteschlitten und Vorschubschlitten neben den ersten Verbindungselementen, über welche die erste Verbindung erfolgt, zweite Verbindungselemente zur Herstellung einer zweiten Verbindung auf. Ist der Arbeitsgeräteschlitten also über die ersten Verbindungselemente auf dem Vorschubschlitten aufgesetzt worden und gegebenenfalls in seiner Montageposition positioniert, kann er über die zweiten Verbindungselemente endgültig mit dem Vorschubschlitten verbunden werden. Im Vergleich zu den im Stand der Technik üblicherweise verwendeten vier Bolzenverbindungen, welche alle erst dann gesetzt werden können, wenn Vorschubschlitten und Arbeitsgeräteschlitten perfekt aneinander positioniert sind, ergibt sich so die Möglichkeit, zunächst den Arbeitsgerätschlitten über die ersten Verbindungselemente auf den Vorschubschlitten aufzuschieben, und erst darauf hin in eine Montageposition so auszurichten, dass die zweiten Verbindungselemente gesetzt werden können.According to the invention, implement carriages and feed carriages have, in addition to the first connecting elements via which the first connection is made, second connecting elements for producing a second connection. If the implement carriage has been placed on the feed carriage via the first connecting elements and, if necessary, positioned in its assembly position, it can be finally connected to the feed carriage via the second connecting elements. In comparison to the four bolt connections commonly used in the prior art, all of which can only be set when the feed carriage and implement carriage are perfectly positioned together, this makes it possible to first push the implement carriage onto the feed carriage via the first connecting elements, and only then then align it into a mounting position so that the second connecting elements can be placed.
Erfindungsgemäß sind die ersten Verbindungselemente dabei bei einer vertikalen Ausrichtung des Mäklers oberhalb der zweiten Verbindungselemente angeordnet. Dies hat den Vorteil, dass bei einem Aufsetzen des Arbeitsgeräteschlittens auf den Vorschubschlitten der Arbeitsgeräteschlitten von sich aus mittels der ersten Verbindungselemente auf dem Vorschubschlitten hängt, so dass er allein durch die Schwerkraft in der richtigen Position gehalten wird. Außerdem erlaubt dies eine besonders günstige Kraftverteilung, bei welcher nur die unteren Verbindungselemente Kräfte entlang der Längsrichtung des Mäklers übertragen.
Weiterhin vorteilhafterweise legen die ersten Verbindungselemente den Arbeitsgeräteschlitten am Vorschubschlitten in einer Montageposition quer zur Längsrichtung des Mäklers fest. Ist der Mäkler zur Montage vertikal ausgerichtet, verhindern die ersten Verbindungselemente nach dem Aufsetzen des Arbeitsgeräteschlittens auf den Vorschubschlitten damit eine Bewegung des Arbeitsgeräteschlittens vom Vorschubschlitten weg. Vorteilhafterweise bilden die ersten Verbindungselemente hierbei eine Drehachse, so dass der Arbeitsgeräteschlitten an den Vorschubschlitten herangeklappt werden kann.According to the invention, the first connecting elements are arranged above the second connecting elements when the leader is aligned vertically. This has the advantage that when the implement carriage is placed on the feed carriage, the implement carriage hangs on the feed carriage by means of the first connecting elements, so that it is held in the correct position solely by gravity. In addition, this allows a particularly favorable force distribution, in which only the lower connecting elements transmit forces along the longitudinal direction of the leader.
Furthermore advantageously, the first connecting elements fix the implement carriage on the feed carriage in a mounting position transverse to the longitudinal direction of the leader. If the leader is aligned vertically for assembly, the first connecting elements prevent the implement carriage from moving away from the feed carriage after the implement carriage has been placed on the feed carriage. Advantageously, the first connecting elements form an axis of rotation, so that the implement carriage can be folded towards the feed carriage.
Erfindungsgemäß legen deshalb die zweiten Verbindungselemente den Arbeitsgeräteschlitten am Vorschubschlitten zumindest in Längsrichtung des Mäklers fest. Dies ist die Richtung, in welcher die z. B. beim Bohren auftretenden Kräfte vom Arbeitsgeräteschlitten auf den Mäkler übertragen werden müssen, so dass die zweiten Verbindungselemente diese Kraftübertragung übernehmen. Insbesondere wenn die ersten Verbindungselemente dagegen eine Bewegung des Arbeitsgeräteschlittens in diese Richtung zulassen, hat dies den Vorteil, dass der Arbeitsgeräteschlitten in Längsrichtung des Mäklers nicht mehr überbestimmt gelagert ist. Hierdurch läßt sich die Kraftübertragung vom Arbeitsgerät auf den Mäkler genau definieren und es kommt zu keinen zusätzlichen Belastungen durch innere Verspannungen.According to the invention, the second connecting elements therefore fix the implement carriage on the feed carriage at least in the longitudinal direction of the leader. This is the direction in which the z. B. forces occurring during drilling must be transferred from the implement carriage to the leader, so that the second connecting elements take over this force transmission. In particular, if the first connecting elements allow the implement carriage to move in this direction, this has the advantage that the implement carriage is no longer mounted in an overdetermined manner in the longitudinal direction of the leader. This allows the power transmission from the implement to the leader to be precisely defined and there are no additional loads due to internal tension.
Weiterhin vorteilhafterweise legen die zweiten Verbindungselemente den Arbeitsgeräteschlitten am Vorschubschlitten in Längs- und Querrichtung des Mäklers fest.Furthermore, advantageously, the second connecting elements fix the implement carriage on the feed carriage in the longitudinal and transverse directions of the leader.
Insbesondere können hier klassische Bolzenverbindungen zum Einsatz kommen. Ist der Mäkler vertikal ausgerichtet, wird der Arbeitsgeräteschlitten am Vorschubschlitten durch die zweiten Verbindungselemente damit vorteilhafterweise so gehaltert, dass lediglich eine Drehbewegung um eine horizontale Drehachse möglich ist. Diese Drehung wird jedoch von den ersten Verbindungselementen verhindert, welche den Arbeitsgeräteschlitten bezüglich dieser Drehachse in tangentialer Richtung festlegen. Dadurch, dass die ersten Verbindungselemente den Arbeitsgeräteschlitten in radialer Richtung zu dieser Drehachse dagegen zumindest zu einer Seite hin nicht festlegen, ergibt sich wiederum der bereits oben beschriebene Vorteil einer Lagerung, welche in vertikaler Richtung nicht überbestimmt ist.In particular, classic bolt connections can be used here. If the leader is aligned vertically, the implement carriage is advantageously held on the feed carriage by the second connecting elements in such a way that only a rotational movement about a horizontal axis of rotation is possible. However, this rotation is prevented by the first connecting elements, which fix the implement carriage in a tangential direction with respect to this axis of rotation. The fact that the first connecting elements do not fix the implement carriage in the radial direction to this axis of rotation at least on one side results in the advantage of a storage already described above, which is not overdetermined in the vertical direction.
Vorteilhafterweise kann erfindungsgemäß der Arbeitsgeräteschlitten zunächst in angewinkelter Position zum Vorschubschlitten durch die ersten Verbindungselemente auf den Vorschubschlitten aufgesetzt werden, woraufhin Vorschubschlitten und Arbeitsgeräteschlitten aneinander herangeschwenkt werden können. Hierdurch ergibt sich eine einfache Montage des Arbeitsgeräteschlittens am Vorschubschlitten über die ersten Verbindungselemente, welche nach dem Auflegen des Arbeitsgeräteschlittens auf den Vorschubschlitten diesen vorteilhafterweise bezüglich einer horizontalen Drehachse lagern, so dass der Vorschubschlitten z.B. durch eine Bewegung des Mäklers an den Arbeitsgeräteschlitten herangeschwenkt werden kann. Sind die ersten Verbindungselemente im oberen Bereich von Arbeitsgeräteschlitten und Vorschubschlitten angeordnet, wird der Arbeitsgeräteschlitten dabei automatisch durch die Schwerkraft in Position gehalten. Insbesondere ist dies von Vorteil, wenn sich die zweiten Verbindungselemente unterhalb der ersten Verbindungselemente befinden.Advantageously, according to the invention, the implement carriage can first be placed on the feed carriage in an angled position relative to the feed carriage through the first connecting elements, whereupon the feed carriage and the implement carriage can be pivoted towards each other. This results in a simple assembly of the implement carriage on the feed carriage via the first connecting elements, which, after placing the implement carriage on the feed carriage, advantageously support it with respect to a horizontal axis of rotation, so that the feed carriage can be pivoted towards the implement carriage, for example by moving the leader. If the first connecting elements are arranged in the upper area of the implement carriage and feed carriage, the implement carriage is automatically held in position by gravity. This is particularly advantageous if the second connecting elements are located below the first connecting elements.
Vorteilhafterweise befinden sich dabei die zweiten Verbindungselemente nach dem Heranschwenken in ihrer Montageposition. Zur Montage des Arbeitsgeräteschlittens müssen also zunächst lediglich die ersten Verbindungselemente zueinander ausgerichtet und ineinander geschoben werden, woraufhin der Vorschubschlitten an den Arbeitsgeräteschlitten herangeschwenkt werden kann, wodurch sich die zweiten Verbindungselemente bereits in Montageposition befinden, so dass diese Verbindung problemlos ohne weiteres Ausrichten hergestellt werden kann.Advantageously, the second connecting elements are in their assembly position after being swiveled in. To assemble the implement carriage, only the first connecting elements must first be aligned with one another and pushed into one another, whereupon the feed carriage can be pivoted towards the implement carriage, whereby the second connecting elements are already in the assembly position, so that this connection can be easily established without further alignment.
Weiterhin vorteilhafterweise umfaßt der erfindungsgemäße Mäkler dabei einen Anschlag für den auf den Vorschubschlitten aufgesetzten Arbeitsgeräteschlitten, welcher insbesondere so ausgeführt ist, dass sich die zweiten Verbindungselemente in ihrer Montageposition befinden, wenn der Arbeitsgeräteschlitten am Anschlag anliegt. Dieser Anschlag, welcher vorteilhafterweise am Vorschubschlitten angeordnet ist, ermöglicht so die genaue Positionierung der zweiten Verbindungselemente in ihrer Montageposition.Furthermore, the leader according to the invention advantageously comprises a stop for the implement carriage placed on the feed carriage, which is designed in particular in such a way that the second connecting elements are in their assembly position when the implement carriage rests against the stop. This stop, which is advantageously arranged on the feed carriage, enables the second connecting elements to be precisely positioned in their assembly position.
Weiterhin vorteilhafterweise ist dabei der Anschlag für den auf den Vorschubschlitten aufgesetzten Arbeitsgeräteschlitten und/oder dessen Gegenelement verstellbar. Hierdurch kann durch das Verstellen des Anschlags bzw. des Gegenelements die Feinjustage zur Positionierung der zweiten Verbindungselemente erfolgen.Furthermore, advantageously, the stop for the implement slide placed on the feed slide and/or its counter element is adjustable. As a result, the fine adjustment for positioning the second connecting elements can be carried out by adjusting the stop or the counter element.
Vorteilhafterweise sind erfindungsgemäß die ersten und/oder die zweiten Verbindungselemente seitlich am Arbeitsgeräteschlitten und am Vorschubschlitten angeordnet. Der Vorschubschlitten ist dabei mit seiner Rückseite dem Mäkler zugewandt und umgreift mit rückseitigen, seitlich angeordneten Führungselementen eine Führung am Mäkler, über welche er entlang der Längsrichtung des Mäklers an diesem geführt wird. Die Vorderseite des Vorschubschlittens stellt dagegen eine Kupplungsebene zum Arbeitsgeräteschlitten dar. Durch die seitliche Anordnung der ersten und/oder der zweiten Verbindungselemente ergibt sich so eine stabile Verbindung.Advantageously, according to the invention, the first and/or the second connecting elements are arranged laterally on the implement carriage and on the feed carriage. The back of the feed carriage faces the leader and surrounds a guide on the leader with rear, laterally arranged guide elements, via which it is guided along the longitudinal direction of the leader. The front of the feed carriage, on the other hand, represents a coupling level to the implement carriage. The lateral arrangement of the first and/or the second connecting elements results in a stable connection.
Weiterhin vorteilhafterweise umfassen die erste und/oder die zweite Verbindung jeweils zwei Verbindungsstellen. Insbesondere können diese jeweils so angeordnet werden, dass sie eine Drehachse bilden. Die Verbindungselemente sind dabei wie im Stand der Technik vorteilhafterweise jeweils rechts und links an den beiden Seiten von Arbeitsgeräteschlitten und Vorschubschlitten angeordnet. So ergibt sich eine sichere und einfach zu montierende Verbindung. Zum Beispiel können die zweiten Verbindungselemente links bzw. rechts an den Schlitten angeordnete Verbindungsstellen aus einander zugeordneten konventionellen Bolzenaufnahmen in Form von Buchsen umfassen, welche jeweils durch einen Bolzen verbunden werden.Furthermore advantageously, the first and/or the second connection each comprise two connection points. In particular, these can each be arranged so that they form an axis of rotation. As in the prior art, the connecting elements are advantageously arranged on the right and left on the two sides of the implement carriage and the feed carriage. This results in a secure and easy-to-assemble connection. For example, the second connecting elements can comprise connecting points arranged on the left or right of the carriage and consisting of conventional bolt receptacles assigned to one another in the form of bushings, each of which is connected by a bolt.
Weiterhin vorteilhafterweise weisen die ersten und/oder die zweiten Verbindungselemente jeweils zwei Bolzen auf, welche links und rechts am Arbeitsgeräteschlitten oder am Vorschubschlitten so angeordnet sind, dass die Bolzen koaxial zueinander ausgerichtet sind. Damit definieren die Bolzenpaare der ersten bzw. der zweiten Verbindungselemente eine gemeinsamen Drehachse. Bei den ersten Verbindungselementen ist dabei jedoch zu beachten, dass deren Bolzenpaar lediglich entweder am Arbeitsgeräteschlitten oder am Vorschubschlitten in einer üblichen Buchse gelagert ist, während die Bolzenaufnahme am jeweils anderen Schlitten erfindungsgemäß ein Herstellen der Verbindung durch eine Relativbewegung von der Schlitten zueinander ermöglicht.Further advantageously, the first and/or the second connecting elements each have two bolts, which are arranged on the left and right on the implement carriage or on the feed carriage in such a way that the bolts are aligned coaxially with one another. The pairs of bolts of the first and second connecting elements thus define a common axis of rotation. With the first connecting elements, however, it should be noted that their pair of bolts is only mounted in a usual socket either on the implement slide or on the feed slide, while the bolt receptacle on the other slide according to the invention enables the connection to be established by a relative movement of the slide to one another.
Vorteilhafterweise umfassen hierzu die ersten Verbindungselemente eine Bolzenaufnahme, welche entlang der Längsrichtung des Mäklers zu einer Seite hin offen ist. Hierdurch kann ein Bolzen durch Bewegen des Vorschubschlittens relativ zum Arbeitsgeräteschlitten in Längsrichtung des Mäklers in die Bolzenaufnahme geschoben werden.For this purpose, the first connecting elements advantageously comprise a bolt receptacle which is open to one side along the longitudinal direction of the leader. This allows a bolt to be pushed into the bolt receptacle by moving the feed carriage relative to the implement carriage in the longitudinal direction of the leader.
Vorteilhafterweise ist die Bolzenaufnahme quer zur Hauptrichtung des Bolzens zu einer Seite hin offen, so dass der Bolzen quer zu seiner Hauptrichtung in die Bolzenaufnahme eingeschoben werden kann. Hierdurch ist es auf einfache Art und Weise möglich, die Bolzen zunächst in den konventionellen Aufnahmebuchsen des einen Schlittens zu montieren und dann die Bolzen quer zu ihrer Hauptrichtung über die offene Seite der Bolzenaufnahme am anderen Schlitten in diese einzuschieben, um den Arbeitsgeräteschlitten auf den Vorschubschlitten aufzusetzen. Vorteilhafterweise ist die Bolzenaufnahme dabei in Längsrichtung des Mäklers offen. Ist der Mäkler vertikal positioniert, heißt dies, dass die Bolzenaufnahme entweder nach oben oder nach unten offen ist, so dass der Bolzen entweder von unten oder von oben in diese hineingeschoben werden kann, während die Hauptrichtung des Bolzens horizontal ausgerichtet ist.Advantageously, the bolt receptacle is open to one side transversely to the main direction of the bolt, so that the bolt can be inserted into the bolt receptacle transversely to its main direction. This makes it possible in a simple manner to first mount the bolts in the conventional receiving sockets of one carriage and then to insert the bolts transversely to their main direction via the open side of the bolt holder on the other carriage in order to place the implement carriage on the feed carriage . Advantageously, the bolt receptacle is open in the longitudinal direction of the leader. If the leader is positioned vertically, this means that the bolt receptacle is open either upwards or downwards, so that the bolt can be pushed into it either from below or from above, while the main direction of the bolt is oriented horizontally.
Weiterhin vorteilhafterweise weist die Bolzenaufnahme eine sich zu ihrer offenen Seite hin vergrößernde Öffnung auf, welche das Einführen des Bolzens von dieser Seite her erleichtert. Hierdurch ist keine genaue Positionierung des Bolzens an der Bolzenaufnahme nötig, da die trichterartige Öffnung den Bolzen führt.Furthermore, the bolt receptacle advantageously has an opening which enlarges towards its open side, which facilitates the insertion of the bolt from this side. This means that precise positioning of the bolt on the bolt holder is not necessary, as the funnel-like opening guides the bolt.
Weiterhin vorteilhafterweise ist dabei die Bolzenaufnahme am Vorschubschlitten angeordnet und nach oben hin offen. Der Bolzen ist damit über eine übliche Aufnahmebuchse am Arbeitsgeräteschlitten insbesondere horizontal befestigt und wird von oben in die Bolzenaufnahme am Vorschubschlitten eingeführt. Der Arbeitsgeräteschlitten hängt so durch die Bolzen am Vorschubschlitten und wird durch die in der nach oben hin offenen Bolzenaufnahme aufliegenden Bolzen gehalten.Furthermore, the bolt receptacle is advantageously arranged on the feed carriage and is open at the top. The bolt is thus fastened, in particular horizontally, to the implement carriage via a usual receiving bushing and is inserted from above into the bolt receptacle on the feed carriage. The implement carriage hangs from the bolts on the feed carriage and is held by the bolts resting in the bolt receptacle, which is open at the top.
Alternativ ist die Bolzenaufnahme am Arbeitsgeräteschlitten angeordnet und nach unten hin offen. Die Bolzen sind damit am Vorschubschlitten in normalen Aufnahmebuchsen insbesondere horizontal gelagert, wobei die nach unten hin offene Bolzenaufnahme am Arbeitsgeräteschlitten an die Bolzen gehängt werden kann.Alternatively, the bolt holder is arranged on the implement carriage and is open at the bottom. The bolts are therefore mounted on the feed carriage in normal receiving bushings, particularly horizontally, whereby the bolt holder, which is open towards the bottom, can be hung on the bolts on the implement carriage.
Weiterhin vorteilhafterweise weisen dagegen die zweiten Verbindungselemente zwei Aufnahmebuchsen auf, welche miteinander verbolzt werden. Die zweite Verbindung durch die zweiten Verbindungselemente erfolgt damit wie im Stand der Technik, wobei jedoch durch die Vorpositionierung durch die ersten Verbindungselemente keine Positionierungsprobleme mehr entstehen, sondern die Bolzen problemlos gesetzt werden können.Further advantageously, however, the second connecting elements have two receiving bushings, which are bolted together. The second connection through the second connecting elements is thus carried out as in the prior art, but the pre-positioning by the first connecting elements no longer causes any positioning problems and the bolts can be set without any problems.
Weiterhin vorteilhafterweise weist der erfindungsgemäße Mäkler am Vorschubschlitten ein Multikupplung zur hydraulischen und/oder elektrischen Ankopplung des Arbeitsgerätes auf. Eine solche Multikupplung erleichtert wiederum das Ankoppeln des Arbeitsgerätes an den Mäkler, wobei die Multikupplung vorteilhafterweise alle hydraulischen und/oder elektrischen Verbindungsleitungen für das Arbeitsgerät umfaßt.Furthermore, the leader according to the invention advantageously has a multi-coupling on the feed carriage for hydraulic and / or electrical coupling of the working device. Such a multi-coupling in turn makes it easier to connect the implement to the leader, with the multi-coupling advantageously comprising all hydraulic and/or electrical connecting lines for the implement.
Neben dem Mäkler nach Anspruch 1 umfaßt die vorliegende Erfindung auch einen entsprechenden Vorschubschlitten nach Anspruch 18 und einen entsprechenden Arbeitsgeräteschlitten nach Anspruch 21, über welche die erfindungsgemäße vereinfachte Montage möglich wird.In addition to the leader according to claim 1, the present invention also includes a corresponding feed carriage according to
Dabei umfaßt die vorliegende Erfindung einen Vorschubschlitten nach Anspruch 18 für einen Mäkler nach Anspruch 1, welcher obere und untere Verbindungselemente zur Verbindung mit einem Arbeitsgeräteschlitten aufweist, wobei die oberen Verbindungselemente nach oben hin offenen Bolzenaufnahmen umfassen. Der Arbeitsgeräteschlitten kann damit die üblichen Aufnahmebuchsen für die Bolzen aufweisen und wird mit bereits montierten Bolzen auf den Vorschubschlitten aufgesetzt, wobei die Bolzen in die nach oben hin offenen Bolzenaufnahmen eingreifen. Insbesondere sind die Bolzenaufnahmen dabei seitlich angeordnet.The present invention includes a feed carriage according to claim 18 for a leader according to claim 1, which has upper and lower connecting elements for connection to a work implement carriage, the upper connecting elements comprising bolt receptacles which are open towards the top. The implement carriage can therefore have the usual receptacle bushings for the bolts and is placed on the feed carriage with the bolts already mounted, with the bolts engaging in the bolt receptacles that are open at the top. In particular, the bolt receptacles are arranged laterally.
Vorteilhafterweise weisen die Bolzenaufnahmen eine sich nach oben hin vergrößernde Öffnung auf, welche das Einführen des entsprechenden Bolzens am Arbeitsgeräteschlitten erleichtert. Hierdurch müssen Arbeitsgeräteschlitten und Vorschubschlitten nur noch ungefähr gegeneinander positioniert werden, da der Bolzen am Arbeitsgeräteschlitten automatisch z. B. bei einem Anheben des Vorschubschlittens in die Bolzenaufnahme hineingleitet.The bolt receptacles advantageously have an opening that enlarges towards the top, which makes it easier to insert the corresponding bolt on the implement carriage. As a result, the implement carriage and the feed carriage only have to be positioned approximately against each other, since the bolt on the implement carriage automatically e.g. B. slides into the bolt holder when the feed carriage is raised.
Weiterhin vorteilhafterweise ist wie bereits beschrieben am Vorschubschlitten eine Multikupplung zur hydraulischen und/oder elektrischen Ankopplung des Arbeitsgerätes vorgesehen, welche die hydraulische und/oder elektrische Ankopplung vereinfacht.It is also advantageous as already described A multi-coupling for hydraulic and/or electrical coupling of the working device is provided on the feed carriage, which simplifies the hydraulic and/or electrical coupling.
Für den Fachmann ist dabei offensichtlich, dass der erfindungsgemäße Vorschubschlitten vorteilhafterweise auch alle weiteren oben bezüglich des Mäklers beschriebenen Merkmale aufweisen kann. Insbesondere können die unteren Verbindungselemente Aufnahmebuchsen für Bolzen aufweisen, über welche der Vorschubschlitten in seinem unteren Bereich mit dem Arbeitsgeräteschlitten verbolzt werden kann.It is obvious to the person skilled in the art that the feed carriage according to the invention can advantageously also have all of the other features described above with regard to the leader. In particular, the lower connecting elements can have receiving bushings for bolts, via which the feed carriage can be bolted to the implement carriage in its lower region.
Alternativ können die zu einer Seite hin offenen Bolzenaufnahmen auch am Arbeitsgeräteschlitten angeordnet sein. Die vorliegende Erfindung umfaßt daher weiterhin einen Arbeitsgeräteschlitten nach Anspruch 21 für einen Mäkler nach Anspruch 1, welcher obere und untere Verbindungselemente zur Verbindung mit einem Vorschubschlitten nach Anspruch 18 aufweist, wobei die oberen Verbindungselemente nach unten hin offenen Bolzenaufnahmen umfassen. Hierdurch ergibt sich die umgekehrte Situation wie bei dem oben beschriebenen Vorschubschlitten, wobei in diesem Fall die am Vorschubschlitten angebrachten Bolzen von unten in die nach unten offenen Bolzenaufnahmen eingeschoben werden können. Auch hier sind die Bolzenaufnahmen vorteilhafterweise seitlich angeordnet.Alternatively, the bolt receptacles, which are open to one side, can also be arranged on the implement carriage. The present invention therefore further comprises an implement carriage according to claim 21 for a leader according to claim 1, which has upper and lower connecting elements for connection to a feed carriage according to
Vorteilhafterweise weisen die Bolzenaufnahmen eine sich nach unten hin vergrößernde Öffnung auf, welche das Einführen des entsprechenden Bolzens am Vorschubschlitten erleichtert.The bolt receptacles advantageously have an opening that enlarges towards the bottom, which makes it easier to insert the corresponding bolt on the feed carriage.
Weiterhin umfaßt die vorliegende Erfindung einen Mäkler nach Anspruch 23 mit einem Arbeitsgeräteschlitten nach Anspruch 21 oder einem Vorschubschlitten nach Anspruch 18, wie sie oben beschrieben wurden. Offensichtlich ergeben sich hierdurch die gleichen Vorteile wie oben beschrieben.The present invention further includes a leader according to claim 23 with an implement carriage according to claim 21 or a feed carriage according to claim 18 as described above. This obviously results in the same advantages as described above.
Ebenso umfaßt die vorliegende Erfindung ein Arbeitsgerät nach Anspruch 24 mit einem Arbeitsgeräteschlitten nach Anspruch 21, wie er oben beschrieben wurde.The present invention also includes an implement according to claim 24 with an implement carriage according to claim 21 as described above.
Die vorliegende Erfindung umfaßt weiterhin ein Verfahren nach Anspruch 25 zur Montage eines Arbeitsgeräteschlittens nach Anspruch 21 am Vorschubschlitten nach Anspruch 18 eines Mäklers nach Anspruch 1 mit den Schritten: Positionieren von ersten Verbindungselementen am Arbeitsgeräteschlitten und am Vorschubschlitten, so dass sie sich gegenüber liegen; Bewegen des Vorschubschlittens relativ zum Arbeitsgeräteschlitten durch die Mäklerkinematik, bis der Arbeitsgeräteschlitten durch die ersten Verbindungselemente auf dem Vorschubschlitten aufsitzt.The present invention further comprises a method according to claim 25 for mounting an implement carriage according to claim 21 on the feed carriage according to claim 18 of a leader according to claim 1, comprising the steps: positioning first connecting elements on the implement carriage and on the feed carriage so that they lie opposite one another; Moving the feed carriage relative to the implement carriage by the leader kinematics until the implement carriage rests on the feed carriage through the first connecting elements.
Durch das erfindungsgemäße Verfahren ergeben sich die gleichen bereits bezüglich des Mäkler beschriebenen Vorteile, insbesondere eine erheblich vereinfachte Montage des Arbeitsgeräteschlittens am Vorschubschlitten, da die ersten Verbindungselemente durch Bewegen Vorschubschlittens des relativ zum Arbeitsgeräteschlitten ineinander geführt werden können, was die Anforderungen an die vorherige Positionierung erheblich senkt.The method according to the invention results in the same advantages already described with regard to the leader, in particular a considerably simplified assembly of the implement carriage on the feed carriage, since the first connecting elements can be guided into one another by moving the feed carriage relative to the implement carriage, which significantly reduces the requirements for previous positioning .
Vorteilhafterweise wird dabei zunächst der Mäkler nach vorne geneigt, so dass die ersten Verbindungselemente ineinander geschoben werden können, ohne dass der Arbeltsgeräteschlitten dem Vorschubschlitten dabei in die Quere kommen könnte.Advantageously, the leader is first tilted forward so that the first connecting elements can be pushed into one another without the work equipment carriage getting in the way of the feed carriage.
Weiterhin vorteilhafterweise wird bei dem erfindungsgemäßen Montageverfahren der Vorschubschlitten relativ zum Arbeitsgeräteschlitten durch die Mäklerkinematik nach oben bewegt. So können z. B. Bolzen in eine nach unten hin offene Aufnahme hineingeschoben werden oder aber umgekehrt eine nach oben hin offene Aufnahme von unten auf Bolzen aufgeschoben werden. Hierdurch ist eine besonders einfache Montage möglich, wobei die Bolzen dabei vorteilhafterweise von einer sich entsprechend weitenden Öffnung geführt werden.Furthermore, advantageously, in the assembly method according to the invention, the feed carriage is moved upwards relative to the implement carriage by the leader kinematics. So you can e.g. B. Bolts can be pushed into a receptacle that is open at the bottom or, conversely, a receptacle that is open at the top can be pushed onto bolts from below. This makes assembly particularly simple, with the bolts advantageously being guided by a correspondingly widening opening.
Vorteilhafterweise werden Arbeitsgeräteschlitten und Vorschubschlitten nach dem Aufsetzen des Arbeitsgeräteschlittens relativ zueinander in einer Montageposition positioniert. Insbesondere wird diese Positionierung durch die erste Verbindung geführt, z.B. indem sie eine Drehachse bildet, um welche Vorschubschlitten und Arbeitsgeräteschlitten zueinander verschwenkt werden können.Advantageously, the implement carriage and the feed carriage are positioned relative to one another in an assembly position after the implement carriage has been placed. In particular, this positioning is guided by the first connection, for example by forming an axis of rotation about which the feed carriage and implement carriage can be pivoted towards one another.
Weiterhin vorteilhafterweise erfolgt das Positionieren des Arbeitsgeräteschlittens relativ zum Vorschubschlitten in einer Montageposition durch ein Aufrichten des zuvor nach vorne geneigten Mäklers. Der Vorschubschlitten wird so an den von den ersten Verbindungselementen aufgrund der Schwerkraft gehaltenen Arbeitsgeräteschlitten herangeschwenkt.Furthermore, the positioning of the implement carriage relative to the feed carriage in a mounting position is advantageously carried out by raising the leader, which was previously inclined forward. The feed carriage is thus pivoted towards the implement carriage held by the first connecting elements due to gravity.
Weiterhin vorteilhaferweise werden Arbeitsgeräteschlitten und Vorschubschlitten in der Montageposition durch zweite Verbindungselemente verbunden. Die zweiten Verbindungselemente stellen so eine sichere Verbindung zwischen Arbeitsgeräteschlitten und Vorschubschlitten her, ohne dass hierzu eine aufwendige und zeitraubende Positionierung nötig wäre.Furthermore, the implement carriage and the feed carriage are advantageously connected in the assembly position by second connecting elements. The second connecting elements thus establish a secure connection between the implement carriage and the feed carriage without the need for complex and time-consuming positioning.
Die vorliegende Erfindung wird nun anhand eines Ausführungsbeispiels sowie Zeichnungen näher erläutert.The present invention will now be explained in more detail using an exemplary embodiment and drawings.

Am Vorschubschlitten 10 ist der Arbeitsgeräteschlitten 20 montiert, welcher das Arbeitsgerät 30 trägt. Da der Mäkler 2 hier zum Bohren dient, handelt es sich bei dem Arbeitsgerät 30 um ein Bohrgetriebe. Um das Transportgewicht und die Transportabmessungen des Mäklers 2 zu verringern, wird häufig das Bohrgetriebe 30 zusammen mit dem Bohrgetriebeschlitten 20 für den Transport vom Vorschubschlitten 10 demontiert und erst am Einsatzort montiert, was nun von der vorliegenden Erfindung erheblich vereinfacht wird.The implement
Ein Ausführungsbeispiel des erfindungsgemäßen Vorschubschlittens, wie er bei dem in
Der Vorschubschlitten weist obere Bolzenaufnahmen 15 und untere Bolzenaufnahmen 16 auf, welche jeweils seitlich links und rechts am Vorschubschlitten angeordnet sind. Die beiden oberen Bolzenaufnahmen 15 liegen sich dabei bezüglich der mittleren Längsachse des Vorschubschlittens spiegelbildlich gegenüber, ebenso die zwei unteren Bolzenaufnahmen 16. Die untere Bolzenaufnahme 16 ist dabei eine Aufnahmebuchse, wie sie aus dem Stand der Technik bereits bekannt ist. Hier können Bolzen entlang ihrer Hauptrichtung in die Aufnahmebuchsen 16 eingeschoben werden, um den Vorschubschlitten mit dem Arbeitsgeräteschlitten zu verbolzen.The feed carriage has
Die oberen Bolzenaufnahmen 15 sind dagegen erfindungsgemäß nicht als Buchsen aufgeführt, sondern nach oben hin offen. Sie bilden damit eine Mulde, in welche ein Bolzen quer zu seiner Hauptrichtung von oben her eingeschoben werden kann. Die Öffnungen der Bolzenaufnahmen 15 werden dabei nach oben hin weiter, so dass ein Einfädeln der Bolzen erleichtert wird. Die Bolzenaufnahmen 15 sind damit entlang der Längsrichtung des Vorschubschlittens und damit des Mäklers 2 nach oben hin offen, so dass entsprechende Bolzen am Arbeitsgeräteschlitten durch eine Relativbewegung von Vorschubschlitten zu Arbeitsgeräteschlitten in die Bolzenaufnahmen 15 eingeführt werden können, so dass eine erste Verbindung zur Vorpositionierung hergestellt ist. Der Arbeitsgeräteschlitten sitzt dann über die Bolzen in der Bolzenaufnahme 15 auf, so dass sich eine Drehachse bildet, um welche die Schlitten aufeinander zu geschwenkt werden können. Die Vorderseite 18 des Vorschubschlittens stellt dabei eine Koppelebene dar, welche der Rückseite eines an den Vorschubschlitten gekoppelten Arbeitsgeräteschlittens zugewandt ist.The
In den
Vor der Montage des Arbeitsgeräteschlittens 20 am Vorschubschlitten 10 werden bereits die Bolzen 35 in die oberen Bolzenaufnahmen 25 am Arbeitsgeräteschlitten gesteckt, oder verbleiben bei der Demontage ohnehin dort. Für die Montage steht der Arbeitsgeräteschlitten mit gesteckten Bolzen 35 auf dem Boden. Der Vorschubschlitten befindet sich unten am Mäkler, welcher mit seinem oberen Bereich leicht nach vorne geneigt wird. Hierdurch können die nach oben hin offenen Bolzenaufnahmen 15 am Vorschubschlitten 10 unter die Bolzen 35 am Arbeitsgeräteschlitten 20 positioniert werden. Durch leichtes Anheben des Vorschubschlittens 10 mittels der Mäklerkinematik können nun die beiden oberen Bolzen 35 in die Bolzenaufnahmen 15 eingefädelt werden. Die sich nach oben vergrößernde Öffnung und die Tatsache, dass nur auf zwei Bolzen geachtet werden muß, erleichtern dabei den Vorgang der Vorpositionierung entscheidend.Before the implement
Die Bolzen 35 ruhen nun in den Aufnahmemulden 15 am Vorschubschlitten, so dass der Arbeitsgeräteschlitten 20 über die von dem aus Bolzen 35 und Bolzenaufnahmen 15 gebildeten Gelenk sich ergebende Drehachse am Vorschubschlitten hängend gelagert ist. Nun kann der Mäkler wieder in aufrechte Position gebracht werden, so dass der Arbeitsgeräteschlitten 20 aufgrund der Schwerkraft um die Achse der oberen Bolzen 35 in die richtige Position einschwenkt. Ein verstellbarer Anschlag begrenzt dabei das Einschwenken in genau der Position, in der die beiden unteren Bolzen 36 ohne Kraftaufwand in die Aufnahmebuchsen 26 und 16 am Arbeitsgeräteschlitten 20 und am Vorschubschlitten 10 gesteckt werden können. Hierdurch ist die Montage des Arbeitsgeräteschlittens 20 am Vorschubschlitten ohne großen Positionieraufwand möglich, wobei die Montage zusätzlich dadurch erleichtert wird, dass die hydraulischen und/oder elektrischen Verbindungen zwischen Mäkler und Arbeitsgerät über die Multikupplung 12 in einem einzigen Arbeitsgang für alle Verbindungsleitungen hergestellt werden können.The
Durch die nach oben hin offene Bolzenaufnahme 15 am Vorschubschlitten, die Aufnahmebuchse 25 am Arbeltsgeräteschlitten und den Bolzen 35 wird so eine erste Verbindung 5 gebildet, welche durch eine Bewegung des Vorschubschlitten 10 relativ zum Arbeitsgeräteschlittens 20 hergestellt wird. Der Arbeitsgeräteschlitten 20 kann so auf den Vorschubschlitten aufgesetzt werden, ohne dass hierfür eine exakte Positionierung nötig wäre. Durch die Aufnahmemulde der nach oben hin offenen Bolzenaufnahme 15 ergibt sich so die erste Verbindung 5, bei welcher der in der Aufnahmemulde aufliegende Bolzen 35 den Arbeitsgeräteschlitten nach unten und zur Seite hin festlegt, so dass sich eine entsprechende Drehachse ergibt. Um diese Drehachse können dann der Arbeitsgeräteschlitten und der Vorschubschlitten aneinander herangeschwenkt werden, wobei bei dieser Relativbewegung von Vorschubschlitten und Arbeitsgeräteschlitten der am Mäkler angeordnete Vorschubschlitten über die Mäklerkinematik bewegt wird. Dabei ist ein nicht gezeigter verstellbarer Anschlag vorgesehen, welcher die Schlitten in der Montageposition der zweiten Verbindungselemente anhält, so dass die Bolzen zu Herstellung der zweiten Verbindung ohne Kraftaufwand gesteckt werden können.The
Die unteren Bolzenaufnahmen 16 und 26 am Vorschubschlitten 10 und Arbeitsgeräteschlitten 20 bilden dabei zusammen mit dem Bolzen 36 die zweite Verbindung, welche den Arbeitsgeräteschlitten relativ zum Vorschubschlitten nach oben und unten sowie nach vorne und hinten festlegt.
