Definitions
- the invention relates to an arrangement with at least two luffing cylinders within a vertical luffing plane between a storage position and a working position luffing jib, the luffing cylinders lying opposite on the luffing plane in the working position enclosing a spreading angle between their longitudinal axes and the luffing cylinders attacking the jib outside of its ends.
- the invention also relates to a mobile crane with such a crane
- Telescopic arrangement on a rotating superstructure opens up correspondingly large work spaces within which the necessary transfer of loads can take place.
- the vertical alignment of the boom which extends essentially horizontally in the process, between its storage position and a working position that is set up in relation thereto, takes place via at least one length-adjustable luffing cylinder.
- a mobile crane with a boom emerges which has a total of two independently operating luffing cylinders.
- the mobile crane has an undercarriage on which the boom is supported in an articulated manner via its lower end.
- the luffing cylinders extending between the boom and the undercarriage are connected in an articulated manner to a region of the boom via their upper ends.
- the lower ends of the luffing cylinders are pivotally supported on the undercarriage in such a way that their longitudinal axes enclose an expansion angle between them. Because the two luffing cylinders can be controlled separately from one another, it is possible to pivot the boom within a vertical luffing plane and also to a limited extent horizontally relative to the undercarriage.
- the A-shaped spread position of the two luffing cylinders relative to one another is based on the desire for a possibility for aligning the boom relative to the undercarriage of the mobile crane that goes beyond the vertical pivotability.
- the only limited lateral pivoting of the boom is due to its design in its storage position on the two in projection on the
- Main boom and a luffing jib known.
- the main boom consists of two main boom arms, which together at one upper end
- Main boom head are mounted and extend from here in a V-shape towards the vehicle. With their lower ends, the two main boom arms are each mounted on the vehicle so that they can be rocked about horizontal axes.
- the main boom arms can be telescoped in opposite directions so that the main boom can be tilted to the left or right. For the bobbing of the two
- the main boom arms are provided with a single telescopic luffing jib, which is also articulated to the main boom head and to a swivel frame on the vehicle.
- the two main boom arms and the luffing jib thus form a tripod starting from the main boom head.
- these are loaded under pressure and the luffing jib is subjected to tension.
- the U-shaped swivel frame is in turn articulated in the area of the horizontal axes of the main boom arms on the vehicle.
- the swivel frame can be swiveled from an erected operating position into a substantially horizontal transport position via a hydraulic cylinder, which is also supported on the vehicle. Together with the swivel frame, the two main boom arms with the luffing jib are thus moved from the other hydraulic cylinder from the operating position to the
- utility model DE 20 2005 015 044 U1 already describes a mobile crane with an undercarriage which can be moved on the road and on which an upper carriage which is pivotable about a vertical pivot axis is mounted.
- a telescopic boom with a basic box and several inner boxes that can be telescoped from it are mounted on the superstructure so that they can be rocked about a horizontal axis.
- the telescopic cylinder is rocked up and down by means of two hydraulic rocking cylinders which are arranged in parallel and at a distance from one another and which are located at their lower ends support on the superstructure and are articulated with their upper ends approximately in the area of the center and on the underside of the basic box of the telescopic boom.
- the present invention is therefore based on the object of the previously known arrangement and a vehicle crane equipped in this way
- the invention proposes that in the case of an arrangement with a jib that can be rocked over at least two luffing cylinders within a vertical luffing plane between a storage position and a working position, the luffing cylinders lying opposite one another on the luffing plane including a spreading angle between their longitudinal axes and the luffing cylinders on the Attack the boom outside of its ends, in the preferred horizontal storage position of the boom the longitudinal axis of a luffing cylinder projected onto the luffing plane and a vertical direction or vertical direction extending within the luffing plane shoot an inclination angle between them.
- the two luffing cylinders are inclined in a side view of the boom as a result of said vertical vertical direction as soon as the boom is in its
- the feature with regard to the luffing cylinders that engage the boom outside its ends is understood to mean that the luffing cylinders engage an area on the boom or the basic box that extends in the longitudinal direction of the boom or one Basic set of the
- Boom seen at least 10%, preferably at least 20%, particularly preferably at least 30%, of the total length of the boom or
- Basic box is spaced from the upper and also the lower end of the boom or the basic box. All in all, the luffing cylinders act more centrally on the extension arm or the basic box than on the head end.
- the resulting advantage lies in the fact that the over
- Boom cylinder-supported booms are no longer raised over their entire component length remaining in the retracted state as soon as it is in its storage position.
- approximately or exactly horizontal alignment of the luffing cylinders significantly less installation space is now required below the boom in the storage position to
- each individual luffing cylinder which is always inclined to the vertical direction in the storage position of the boom, ensures that the position of its end connections, which have hitherto been superimposed, is offset from one another due to the horizontal and vertical components resulting from the inclination. Since the upper end connection of each inclined luffing cylinder is pivoted in a circular path around its lower end connection, the boom can be aligned correspondingly lower in its storage position.
- the tilt angle of the luffing cylinder in relation to the vertical direction can be from 60 ° to 120 ° in the storage position of the boom. This makes it possible for each luffing cylinder to extend not only up to + 30 ° above a horizontal, but also down to -30 ° below the horizontal position of the boom.
- the boom in its storage position can also incline upwards or downwards with respect to the horizontal and extend parallel to it.
- the luffing cylinders can extend almost parallel to the horizontal in the storage position of the boom, the angle of inclination of which relative to the vertical direction then being preferably from 80 ° to 100 ° or from 90 ° to 97 °.
- the arrangement can comprise a base frame, on which the boom is rocked with its lower end.
- the rocker cylinders are also articulated on the base frame.
- lower bearing arrangements designed as universal joints or ball-and-socket joints, for example, can advantageously be provided, via which the rocker cylinders are correspondingly connected to the base frame.
- the cantilever arm mounted on a base frame can comprise upper bearing arrangements, which are then each assigned to an upper end of one of the two Wpp cylinders. That way they are
- Rocker cylinders are also articulated at their upper ends via the upper bearing arrangements on the boom.
- the upper bearing arrangements can preferably be designed as a universal or ball joint.
- At least one of the bearing arrangements mentioned above can be relative to the base frame
- bearing arrangements enable a corresponding change in the spreading angle between the wrap cylinders, as a result of which the spreading angle enclosed between them can be opened downwards (A-shape) or upwards (V-shape).
- the two Wpp cylinders can have an A-shape or a V-shape with one another from a frontal view.
- the upper ends of the Wpp cylinders on the boom in the orthogonal direction to the luffing plane are further apart than their opposite lower ends on the base frame. The same applies vice versa for the A-shape.
- the V shape enables a more compact
- the position resulting from the A-shaped or V-shaped position which stabilizes the arm in particular in its A-shape against lateral influences, can be obtained If necessary, increase the effect in an advantageous manner, for example.
- the displacement of the bearing arrangement of at least one rocking cylinder enables even more compact dimensions of the arrangement according to the invention if required.
- the at least one bearing arrangement can preferably be shifted closer to the boom in the storage position by the lateral dimensions of the
- the spreading angle which decreases at the same time, is able to reduce the lateral stability of the boom, but this is irrelevant anyway, particularly in its storage position.
- Directions can be shifted towards or away from each other along the associated path.
- the inclination of the two luffing cylinders can be changed to the same extent, so that their connection to the boom always remains within the luffing plane, while the spreading angle between the longitudinal axes of the luffing cylinders is changed. This effectively prevents an undesired transverse displacement of the boom when the bearing arrangement (s) are moved.
- the arrangement according to the invention can preferably be designed such that not only in the storage position but also in an assumed working position of the
- Cantilever whose lateral stabilization can be increased if necessary by at least one of the two lower and / or upper bearing arrangements of the luffing cylinders being correspondingly displaceable in opposite directions. Overall, it is considered advantageous if the spread angle between the longitudinal axes of the two Luffing cylinder in the storage position and / or in the working position of the boom is changeable.
- the spreading angle opened downwards or upwards in the working position of the boom can be greater than 0 ° to 45 °.
- the spreading angle opened downwards or upwards in the working position of the boom can be from 2 ° to 30 °.
- the value of the spreading angle opened downwards or upwards in the storage position of the boom can be particularly preferably from 0 ° to 45 ° or from 0 ° to 6 °, so that an at least approximately parallel alignment of the luffing cylinders, for example during the process, is one with the one according to the invention Arrangement equipped crane vehicle is enabled.
- the base frame can be a component that can be connected, for example, to a region of a mobile crane, it is considered to be advantageous if the base frame itself is part of one versus one
- Undercarriage is a rotating superstructure of a mobile crane.
- the base frame itself can be an uppercarriage or can be designed as an uppercarriage.
- the base frame itself can be part of the
- the base frame itself can be such an undercarriage, or as
- Undercarriage can be formed.
- Mobile crane can forward. Because of the at least in the working position of the boom A-shaped or V-shaped alignment of the two luffing cylinders to one statically advantageous and extremely stable triangle, in particular in the A-shape, the forces acting laterally on the boom can now at least partially be absorbed and transmitted, which means that the pivoting mounting of the boom and the base frame itself with regard to the capacity of such forces can be absorbed much simplified. As a result, said pivotable structural mounting of the boom and the base frame can, for example, be made correspondingly cheaper and slimmer.
