The milling roller that generally includes the support column of hollow cylinder has multiple power tools, particularly cutter arrangement.Certainly, due to ground milling machine, large material load during the job run of road milling machine particularly, the cutter arrangement of milling roller must be subject to high wearing and tearing.In addition, also have other devices in the milling roller case of road milling machine, for example, use for example injection device of water, pitch and/or foamed asphalt, described injection device is the same with cutter arrangement, must often safeguard.For carrying out foregoing upkeep operation, need to enter the inner chamber of milling roller case.Described in ensureing, enter, conventionally utilize milling roller chamber door or scraper.Described scraper is adjusted to its maintenance position therefore entering of the open inner chamber to milling roller case by adjusting device.In order to guarantee, scraper remains in its maintenance position within the period of maintenance work, is conventionally provided with locking device in a side of ground milling machine, and described locking device remains on scraper in its maintenance position in frame.For safety reasons, locking device is not for making swing mechanism that scraper moves between its job position and its maintenance position or a part for adjusting device, and can not unclamp by the control device that is used for activating adjusting device.Be provided with on the contrary the manually operated executive component of independent energy, before milling roller chamber door can reset to the job position of reduction from putting high maintenance position, can and must only utilize described executive component to unclamp locking device.Guaranteed by this separation, as long as have within personnel rest on the wobble area of scraper, scraper just can not move and leave its maintenance position.Therefore before locking device swings and gets back to its job position, must be manually and be independent of for the control device of swing mechanism unclamp locking device.This manual unclamping from a position of milling roller case side direction carried out, and from this position, operator can see and in operating direction, is positioned at the wobble area of the scraper after milling roller case and can confirms not have personnel to rest on there.After manually unclamping locking device, operator also will operate the control device for swing mechanism, and starts thus scraper and enter the reseting movement of job position.Again seal thus milling roller case and can start job run.Locking device side direction on a longitudinal side of ground milling machine is positioned at the region of milling roller case, and here operator can see the wobble area of scraper, also can stand on outside this wobble area on the side of milling roller case safely.The operating means that only could be arranged on equally side by operation from this lateral position unclamps locking device.Guarantee by this known arrangement, in the time that operator closes milling roller case, under operator is in a safe condition.But make again the operator must be always from this position end maintenance work simultaneously.If operator is positioned at the contrary side of ground milling machine after maintenance work, operator must intactly walk around ground milling machine, so that final power cut-off.Particularly, under narrow condition, in the time that for example ground milling machine is near wall, slope or other corners, this is very impracticable and allows people feel trouble.
Summary of the invention
Therefore, task of the present invention is to provide a kind of locking device of the removing device for ground milling machine, described locking device is guaranteed operator's safety during maintenance work, and can imperative operation person from definite position end maintenance work of ground milling machine, also there is simple and economic structure simultaneously.
This task is by realizing according to the ground milling machine of independent claims, particularly road milling machine, machine for trimming, stabilizing machine or surface miner.Preferred expansion scheme provides in each dependent claims.
The ground milling machine of described type, particularly road milling machine, machine for trimming, stabilizing machine or surface miner have frame, milling roller, with the milling roller case of scraper, described scraper forms milling roller case along the rear wall of work aspect and can between job position and maintenance position, swing, in described job position, scraper sealing milling roller case, in maintenance position, entering of the inner chamber of described scraper opening to milling roller case, also there is locking device, described locking device can unclamp scraper and be fixed in maintenance position, also there is the manually operated executive component of energy, after the described executive component of operation, again discharge described locking device.The present invention now realizes for the basic conception of the described object of such ground milling machine and being, on two opposed longitudinal sides of ground milling machine, an executive component for operational lock device is set respectively.The inside in the region of at least one executive component at least two executive components described in can touching at least thus, can be selectively by two opposed longitudinal sides of ground milling machine operational lock device that sets out.Same possible and comprise in the present invention in principle, be provided with more than two executive components, for discharging the same locking device on ground milling machine, to further improve the scope of possible operating position.But verified in actual applications, the form of implementation that lucky two executive components are set on ground milling machine has formed structure consumes and the half-way house for the best between user's use value.These executive components are positioned at the region of the side of milling roller case aptly, and described side is crossing with the rotation of milling roller.Two opposed longitudinal sides of ground milling machine are the sides that is parallel to the operating direction of ground milling machine or extends perpendicular to the rotation of milling roller.Common described side is obviously long than front side and rear side.By an executive component being set respectively on these two sides of ground milling machine, operator also can be correspondingly from both sides release locking device.Thus, even when near the narrow condition lower time of ground milling machine wall, slope or other obstructions, also can finish the maintenance work to milling roller.
According to the present invention preferably, locking device being arranged in frame in central authorities on the width transverse to operating direction at scraper.This means in other words, locking device is arranged on machine central authorities about the width transverse to operating direction of ground milling machine, instead of is arranged on fringe region.Therefore, scraper equally separates spacing with two longitudinal sides of ground milling machine ideally, and at least (deviation) is in the scope of +/-10%.In addition,, for the each from two longitudinal sides can easily be operated, executive component is also preferably arranged on identical height about the length of ground milling machine.Therefore it is irrelevant that the machine operator who operates described executive component with hope is positioned at right side or the left side of ground milling machine now, and operator can find described executive component on close position.
Also advantageously, the direction setting towards the scraper seamed edge of scraper about the height of scraper by locking device.The oscillating motion of scraper realizes by the swing hinge between milling roller chamber door and frame conventionally, described swing hinge be arranged on scraper with the opposed side of scraper seamed edge on.This layout away from hinge by locking device on the material scraping plate of scraper, the confining force that can keep the needs of locking device to apply is less.
In the time that two executive components are positioned in common operative axis, can realize especially simply design of the present invention.Like this, executive component can be arranged on simply on identical height on opposed longitudinal side of ground milling machine.Here best, two executive components also directly, particularly preferably along described axis by suitable Connection Element, for example connecting rod, particularly directly interconnect.Can obviously simplify thus overall structure.
For smooth work of the present invention importantly, guarantee the operation of any executive component can trigger reliably the corresponding operating to locking device, and irrelevant with which executive component of concrete operations.But here in principle each existing executive component also can with locking device Function Coupling individually.But it is desirable to, be provided with coupling device, described coupling device at least in function and ideally also on entity, particularly directly by make locking device be connected with two executive components according to foregoing Connection Element, and will the releasing operation of corresponding in described at least two executive components be delivered on locking device.First therefore a critical function of coupling device be the releasing operation to executive component to be delivered on locking device.Coupling device is in the ideal case for carrying out the transmission of adjusting power from executive component to locking device.Specifically transmit which power and how to carry out this transmission, depending on concrete form of structure.For example two executive components can have common axis of rotation line, and the revolving force of executive component is delivered on locking device by coupling device via this rotation.It is contemplated that equally, two executive components are positioned on common translated axis line, by described translated axis line, linear force or motion are delivered to locking device via coupling device from executive component.Also can consider in principle to adopt transmission scheme electronic, hydraulic pressure and/or that motor drives, wherein these transmission schemes are because higher structure consumes is not preferred with respect to the coupling device of pure mechanism.
Scraper or milling roller chamber door are conventionally configured to very firm and have a larger quality.By consequent large gravity, for removing by locking device, scraper is remained on to the required adjusting power of the locking of maintenance position, for example higher for overcoming the adjusting power of corresponding frictional force.For the operation of executive component is become easily, preferably, coupling device comprises transmission device, can provide favourable gearratio by means of described transmission device, so as to reduce as far as possible that user will apply for operating the adjusting power of described executive component.Supplement or alternatively, also can set, for release locking device, scraper is lifted slightly from its maintenance position, so that the maintenance load on reduction locking device, thus then locking device can move to its corresponding off-position, to discharge scraper.Therefore, in principle and particularly for this form of implementation, it is also preferred that according to the present invention, be provided with the operating unit for scraper of for example guidance panel form, for example can operate the swing mechanism/hydraulic means for scraper by described operating unit, described operating unit is spatially positioned near a corresponding executive component, thereby can also operate scraper by single personnel's while both operational lock device.Therefore on space near specifically referring to such scope under present case, personnel can be set out and can be touched described scope by a position for the object operating, described scope for example refers to the distance lower than half meter.
Particularly, coupling device can be for example push rod.The salient point of push rod is, described push rod is configured for transmitting linear promotion or pulls motion, so that operational lock device.As mentioned, preferably, can operate a common push rod by least two executive components respectively here above.But coupling device preferably includes transmitter shaft.Described transmitter shaft will rotatablely move and will be delivered on locking device by corresponding executive component.Conventionally the direction of rotation that transmitter shaft transmits is here unimportant.But preferably such form of implementation, wherein transmits the direction of rotation for release locking device, and this direction of rotation realizes along the direction of gravity at least in part.In this form of implementation, operator also can utilize it to conduct oneself with dignity to operate.In addition, coupling device supplements or for example comprises alternatively chain driving member or rope drive part, and chain driving member or rope drive part be both applicable to transmit linear movement, were also applicable to transferring rotational motion.
In general sense, locking device specifically refers to such device, scraper releasably can be fixed in maintenance position by this device.Locking device is preferably included in the retaining element on milling roller chamber door or scraper for this reason, and be connected in function with executive component, with above retaining element shape interactional retaining element in locking manner particularly under stationary state.To this, can consider in principle the replacement scheme of employing, particularly use kayser hook to prove particularly preferred, described kayser hook embeds in holding element.Here kayser hook being connected in function with executive component ideally, and holding element, for example suitable maintenance ring are arranged on scraper.Equally also kayser hook can be formed on scraper, and holding element is formed in frame.
Preferably at least described kayser hook can move and support between initial position and deviation position, described initial position is also interlocking position, and in described interlocking position, kayser hook and holding element are in interlocking, in described deviation position, kayser hook discharges described holding element.Here can be implemented to the interlocking in holding element with form in a different manner, wherein particularly preferably be the scheme of weight-driven.In this form of implementation, kayser hook is bearing in frame Shangdi and for example hangs downwards on gravitate ground, and now make its motion leave this position by the scraper moving in maintenance position or the holding element that is arranged on scraper, for example, by sliding past the corresponding sliding bevel on kayser hook.Once scraper arrives maintenance position, kayser hook is because interlocking position is returned in gravitational motion, and in this interlocking position, kayser hook overlaps from behind now holding element and thus scraper is fixed in maintenance position.This interlocking realizes with the sealed form of the shape between kayser hook and holding element here, and avoided not in advance operating operation element discharge locking member in the lump in the situation that discharge holding element.
A kind of optional form of implementation is set, and kayser hook is loaded by spring towards the direction of its interlocking position.In this form of implementation, it is to overcome spring loading kayser hook is pushed to deviation position from interlocking position that the holding element of scraper is upwards dug at milling roller chamber door.Next be correspondingly subject to Spring driving and realize the reseting movement of kayser hook to interlocking position.
Except having the form of implementation of transmission device, kayser hook can be connected with form by coupling device by this way with two executive components, and the motion of one of two executive components is directly delivered on kayser hook.In other words, one of two executive components rotatablely move or linear movement is directly converted to kayser hook and rotatablely moves accordingly or linear movement.Being connected between executive component and kayser hook is rigidity here, and this connection of particularly fixing each other by these elements realizes.Therefore the special feature of this form of implementation is, there is ideally (also can be formed by multiple subdivisions that are fixedly connected to each other if desired) element of one, described element has two executive components of putting toward each other, coupling element, particularly the connecting rod between two executive components, connector in frame and the latch elements of locking device.
