Definitions

  • the invention relates to the technical field of guying in telescopic cranes, in particular in mobile cranes.
  • Guying systems are used on cranes or telescopic cranes to increase the load-bearing capacity of the boom or its stability or rigidity.
  • the guying device is provided as an integral unit and is also referred to as a "guying frame”. It has erectable guying supports and a holding frame for attachment to the crane boom. Ropes are stretched to the boom head via the guying supports, which partially absorb the forces acting on the boom and thus provide relief or improve rigidity.
  • the guying supports are attached via guying links in the area of the boom rotation axis.
  • the dimensions and weight of the guying unit also increase, so that it cannot be pre-assembled on the boom when the crane is transported to the site, as otherwise height and/or weight restrictions would not be met. In these cases, the guying unit is transported to the site separately.
  • the EP 1735233 A1 proposes to design the entire guying device as a single unit, which can be lifted by the crane at the site as part of the transport vehicle. In order to equip the guying device on the boom, it is placed on the ground in an elevated position using a support frame, so that the crane boom can be retracted under the guying device and the guying device can be mounted on the boom from above.
  • EP 2248754 A1 therefore proposes placing the guying device as a structural unit directly on the crane undercarriage in order to mount the guying device "from below" on the boom after the boom has been extended or luffed. Since with this solution the luffing cylinder(s) have to be guided past the guying supports and the overall width of the guying device cannot exceed a certain value due to the approval regulations for road transport, this solution is subject to strict limits with regard to the geometry of the guying device and the boom including its luffing mechanism.
  • the publications CN 106044589 A , CN 105293318 B , EP 2248754 A1 and CN 202766156 U disclose further guying devices according to the preamble of patent claim 1.
  • the telescopic boom guying unit therefore comprises a holding frame designed for attachment to the telescopic boom of the mobile crane with an open cross-section, the cross-sectional opening of which enables the boom to be retracted in the holding frame, and two guy supports connected by the holding frame to form a structural unit.
  • Two frame parts forming the open cross-section of the holding frame are movably coupled to one another via a coupling point.
  • Two frame parts forming the open upper section are movably coupled to one another via a coupling point lying essentially on the plane of symmetry of the holding frame, such that a movement of the frame parts relative to one another causes a change in the opening width of the open cross-section and the holding frame has an essentially symmetrical cross-section in every position of the frame parts relative to one another.
  • the support frame by means of which the guy supports are attached to the boom, has a substantially U-shaped cross-section, so that the boom can be introduced into the boom by means of a rocking movement over the opening of the U-shaped support frame in order to set up the guy device, and this can ultimately be bolted to the boom.
  • the open cross-section is formed by two frame parts that are movable relative to one another, but still form a structural unit.
  • the profile cross-section of the support frame can be varied by moving the frame parts relative to one another, so that different profile cross-sections of the support frame can be achieved by different positions of the frame parts relative to one another, which in turn meet different geometric requirements for the guy unit.
  • the support frame can extend essentially in a plane that perpendicularly intersects the longitudinal axis of the boom retracted into the support frame.
  • the frame parts can also move relative to one another in this plane.
  • the movement of the frame parts relative to each other will cause a change in the opening width of the open cross-section.
  • the frame parts can be moved relative to each other in such a way that the opening available for retracting the boom into the support frame is widened or narrowed again. Since the position of the two guy supports is determined by the position of the respective frame parts of the support frame, the width between the guy supports of the guy device as a whole is also influenced.
  • the width of the guying unit can also be changed by moving the frame parts relative to each other.
  • the holding frame can be designed in such a way that the width of the holding frame and thus of the entire guying unit can be varied by moving the frame parts relative to each other.
  • the coupling point can couple the respective frame parts of the holding frame to one another in a rotational manner.
  • the frame parts can be connected to one another via a rotary joint, the axis of rotation of which runs parallel to the longitudinal axis of the boom retracted into the holding frame.
  • the coupling point can also couple the respective frame parts to one another in a translational manner, so that they can be moved relative to one another, for example via a rail-like guide. It is also conceivable that the coupling point enables a combined rotational/translational movement of the respective frame parts relative to one another.
  • the coupling point lies essentially on the plane of symmetry of the holding frame, so that the holding frame has an essentially symmetrical cross-section in every position of the frame parts relative to one another.
  • the bracing unit can have at least one electrically, mechanically or hydraulically driven actuator, by means of which the frame parts of the holding frame are moved relative to one another, in particular rotated relative to one another and/or displaced relative to one another.
  • frame parts coupled to one another in a translational manner can be displaced relative to one another via a hydraulic cylinder, a rack and pinion drive, an electric or hydraulic motor or similar in order to vary the opening width of the open frame cross-section and/or to change the overall width of the holding frame or the bracing unit.
  • a rotary movement of the frame parts relative to one another is caused by means of a hydraulic cylinder or an electric or hydraulic motor arranged in the area of the axis of rotation. It is also possible for the frame parts to be moved relative to one another by an "external" drive. such as a drive on the crane undercarriage or on the transport unit/low loader.
  • the holding frame can also be designed in such a way that the opening of the open cross-section expands automatically as soon as it is lifted by the crane.
  • This automatic expansion can also take place when the guying unit is in a lowered rest position, in particular when it is lowered onto the crane undercarriage for rigging.
  • the tendency of the guying unit to expand as soon as it is attached to the crane's load hook or lowered onto the crane undercarriage can be achieved by a suitable choice of frame geometry and the position of the respective centers of gravity of the frame parts and their supports.
  • the frame cross-section can be transferred from an expanded position back to a position adjacent to the boom cross-section by retracting the boom into the holding frame using a rocking movement.
  • the frame parts automatically rest against the profile of the boom when the boom is retracted, so that the guying unit can be bolted to the boom in a subsequent step.
  • the guying unit according to the invention is mounted on the boom "from above” with a variable holding frame profile.
  • the present invention also enables rigging "from below” by retracting the boom into the holding frame by lowering or luffing the boom. While in the first case a holding frame is necessary in order to be able to set the guying unit down in an elevated position so that the boom can be moved under the guying unit for rigging, in the second case the guying unit can be set down directly on the crane undercarriage, for example.
  • the guying unit can have defined supports, which then act as a positioning aid, so to speak.
  • the holding frame or the guying unit can open or expand automatically under its own weight in a lowered resting state.
  • a further aspect of the present invention relates to a guying unit transport system which, in addition to the guying unit described here, also comprises a transport vehicle designed to transport this guying unit.
  • the guying unit can be designed in such a way that it expands automatically, particularly when it is in a resting position on the crane undercarriage, it can, in conjunction with the transport vehicle intended for it, strive in a very similar way to reduce its overall width when it is placed on the transport vehicle. This not only ensures that the maximum width permitted for road transport is not exceeded, but also allows the narrowest possible transport vehicle to be used.
  • a further aspect of the present invention relates to a telescopic crane, in particular a mobile crane, with an upper carriage rotatably arranged on an undercarriage with a telescopic boom comprising several telescopic sections, and a guying unit as described here.
  • a further aspect of the present invention relates to a setup method for the telescopic boom guying unit according to the invention, according to which a guying unit transported separately from the mobile crane is lifted by the transport vehicle and placed on the undercarriage of the mobile crane, whereupon the boom is retracted into the holding frame by a rocking movement and bolted to it.
  • the Figure 1 shows a guying unit 9 according to the present invention, transported separately from the rest of the mobile crane on a low-loader 8.
  • the guying unit 9 takes up a position on the low-loader 8 in which it has a smaller overall width than in a position bolted to the boom 3 or even placed on the crane undercarriage 1.
  • the Figure 7 illustrates how the smaller overall width of the guying unit 9 can be achieved, namely by rotating the two frame parts 101 and 102 about the swivel joint 19, so that the latter assumes a lower position relative to the frame parts 101 and 102 than in a normal position.
  • the Figure 2 shows a perspective view of the guying unit 9 according to the invention, which essentially consists of two symmetrically arranged guying supports 11 and the associated holding frame 10.
  • the holding frame 10 is divided into two frame parts 101 and 102, which can be rotated relative to each other about the central pivot joint 19.
  • the guying unit 9 In the state shown of the guying unit 9, it is suspended from a crane hook 30 by means of the slings 21.
  • the slings or ropes 21 engage in the area of the swivel joint 19 and the support supports 17, so that the guying device 9 expands automatically due to its own weight, i.e.
  • the guying supports themselves are designed in a manner already known. In particular, they each have a winch 16 for the boom guying and are erected in the boom luffing plane by means of the erection cylinders 12 and then pulled back in again after use, while they can be moved out of the boom luffing plane and back into it by means of the respective swivel blocks 13 and swivel cylinders 14.
  • the guy supports 11 can therefore assume a so-called V or Y position, whereby the boom guying can also absorb lateral loads, such as wind loads on the crane boom 3.
  • the Figure 3 shows the next step in setting up the guying device 9 according to the invention, in which it is placed in the front area of the crane undercarriage 1. It is clear that the positioning of the guying unit 9 on the crane undercarriage 1 can be carried out independently by the mobile crane, so that no separate lifting gear needs to be provided.
  • the Figure 4 shows the guy unit 9 positioned on the crane undercarriage 1, whereby it should be noted that the supports 17 and 18 of the guy unit 9 come to lie in defined areas of the crane undercarriage 1 in order to be able to bolt the guy unit 9 to the boom 3 as soon as this has been retracted into the holding frame 10 or its frame parts 101 and 102.
  • the holding frame 10 is bolted to the collar 6 of the base body 4.
  • the boom 3 must be lowered (tilted down or out) into a substantially horizontal position so that the collar 6 moves into the holding frame 10 and comes to lie in it.
  • FIG. 4 An essential aspect of the present invention is the Figure 4 also to be taken from: as the previous Figures 1 to 3
  • the guy supports 11 of the guying device 9, which is separate from the rest of the mobile crane are aligned parallel to one another.
  • the space available between the guy supports 11 is therefore directly dependent on the distance between the upper ends of the U-shaped holding frame. If more space is required to extend and retract the boom 3 from the holding frame 10, this was previously only possible by increasing the overall width of the holding frame 10. However, this, as well as the entire guying device 9 itself, must not exceed a given maximum width when transported separately from the mobile crane on a low-loader 8.
  • the guy supports 10 can be brought back to the boom 3 by the frame parts 101 and 102 being placed against the boom or the collar 6. In the example shown, this is achieved by the collar 6 running onto the pivot joint 19 located centrally underneath and pressing it downwards.
  • the supports 18 on both sides of the holding frame 10 and supporting it roll on the crane undercarriage 1 and thus enable rotation of the respective frame parts 101 and 102 resting on the crane undercarriage 1.
  • a rail-like guide structure 20 ( Figure 4 ) which allows the supports 18 to roll but prevents them from moving in the longitudinal direction of the crane.
  • this can be done by one or more grooves and/or rails transverse to the longitudinal direction of the crane, in which the supports 18 are held by the dead weight of the guying device 9, even if they roll on the crane superstructure 1.
  • the guide structure 20 can be adapted to the translational rather than rotational movement.
  • the guide structure 20 can allow movement of the frame parts 101 and 102 or their supports 18 during setup, but prevent movement in the longitudinal direction of the crane.
  • a guide structure can also be provided for the rear supports 17. Since in the embodiment shown these rest on the crane undercarriage 1 essentially at the same point when rolling, the guide structure there can take the form of an indentation or recess on the crane superstructure 1, which prevents the respective supports 17 from a translational movement in any horizontal direction. If such a translational movement is desired, for example in the transverse direction of the crane, the guide structure for the rear supports 17 can of course also have rails or grooves, as have already been described for the front guide structure 20.
  • the Figure 6 shows the holding frame 10 of the guying unit 9 according to the invention in a state applied to the boom 3, in which the holding frame 10 can be bolted to the collar 6 of the outermost telescopic section 4 by activating the locking cylinders 15.
  • the Figures 7 to 9 The cross-sections of the different positions of the frame parts 101 and 102 to each other once again illustrate the advantages of the present invention:
  • the Figure 9 shows a normal position of the frame parts 101 and 102 relative to each other, in which the holding frame 10 rests on the outer circumference of the boom 3 or on the collar 6 and can be bolted to it. In this position, the extension and retraction of the boom 3 into and out of the holding frame 10 is not possible, since the available opening width D6 is not sufficient for this. Furthermore, it is possible that the Figure 9 visible construction width D3 exceeds a permissible maximum value for road transport.
  • the present invention solves both problems by pivoting the frame parts 101 and 102 towards each other via the central pivot joint 19. On the one hand, it is thus possible to widen the opening width of the holding frame 10, which is relevant for retracting and extending, to a larger distance D5.
  • the construction width D2 which is also larger than the construction width D3 of the normal position, is not important here, since this position is only assumed at the site of use when the mobile crane is set up.
  • the frame parts 101 and 102 of the embodiment shown are pivoted in the opposite direction to each other, so that the construction width D1 of the guying device 9 assumes a value that is permissible for road traffic and smaller than the construction width D3 of the normal position.
  • the opening width D4 which is reduced compared to the normal position, is again not important in the transport state.
  • FIGS 10 to 12 show an embodiment of the guying device 9 according to the invention, in which the frame parts 101 and 102 are not as in the Figures 7 to 9
  • the embodiment shown here is not moved rotationally relative to each other, but rather translationally.
  • This translational movement in horizontal Direction is effected by an actuator 21, which is in the Figure 12 shown schematically as a hydraulic cylinder, but can also comprise a rack and pinion drive or similar means suitable for a translational movement.
  • Figure 10 a transport position with reduced widths D1 and D4 (according to the Figure 7 shown rotational position), the Figure 11 a setup position with extended widths D2 and D5 (according to the Figure 8 shown rotational position) and the Figure 12 a working position of the frame parts 101 and 102 (according to the Figure 9 shown rotary position), whereby the frame parts 101 and 102 can be bolted to the crane boom 3 in the latter position.
