Description

Technical Field

[0001] This invention belongs to the field of automobile crane technology and relates to a flexible crane support structure that avoids interference between multiple vehicle models on the same line. Background Technology

[0002] With the current development of the automotive industry, the co-production of multiple models on the same line is an inevitable trend. The more models there are, the greater the difficulty in modifying and designing the lifting equipment, and the higher the demand for local product design. This problem limits the development of models and also increases the investment in special process structures for certain parts of the product.

[0003] Patent document CN113336071A discloses a Y-axis adjustment mechanism for a lifting device fulcrum. In this mechanism, a rotating shaft passes through the base plate of the outrigger assembly. A rotating shaft support is provided on the outside of the rotating shaft. One end of the rotating shaft is connected to one end of a rotating arm, and the other end of the rotating arm has a hub that fits into a guide groove. A spherical plunger is provided on the rotating shaft support, and a limiting hole adapted to the plunger's head is provided on the rotating shaft. Rotation of the rotating shaft drives the rotating arm to rotate, causing the hub to displace within the guide groove. During this arc-shaped displacement, the hub pushes the groove wall, thereby pushing the fulcrum push plate to perform linear displacement on the outrigger assembly. When the rotating assembly is in its final position, the plunger's head enters the limiting hole, achieving automatic positioning of the entire mechanism. This mechanism has a simple, compact, and enclosed structure, suitable for transferring the support position of the lifting device to different vehicle models. It increases the flexibility of the lifting device fulcrum and provides high positioning efficiency.

[0004] The aforementioned patent differs from the rotary plunger positioning in this application.

[0005] Patent document CN110510495A relates to a fulcrum rotation switching positioning mechanism for a lifting device. Its features include: a fulcrum rotation component connected to a fixed mounting base; a sliding bearing housed within the cavity of the fixed mounting base; a wear-resistant pad on the upper surface connected to the fulcrum rotation component; the fulcrum rotation component passing through a rotating central shaft within the fixed mounting base; a hollow cavity structure on the inner side of the rotating central shaft; an elongated hole on the wall of the rotating central shaft; a fixed fulcrum rotation positioning component to the rotating shaft; the rotating shaft connected to the inner cavity of the rotating central shaft; a positioning key sliding on the elongated hole of the rotating central shaft; end faces and inclined guides at the lower part of the inner cavity of the fixed mounting base; a connecting plate on one side of the fixed mounting base connected to the lifting device arm; an elongated hole on the connecting plate; and a rotating support on the other side of the fixed mounting base. Its structure is closed and compact, ensuring accurate fixture positioning; increasing the safety of the positioning component; improving work efficiency; and accelerating production cycle.

[0006] The aforementioned patents differ from this application in that they involve rotational switching positioning.

[0007] Patent document CN111687011A discloses a fulcrum locking device for a pre-treatment hanger for automotive body painting, comprising a vertically movable lifting base assembly, a horizontally movable transverse base assembly mounted on the lifting base assembly, a locking actuator mounted on the transverse base assembly for controlling the rotation angle of the fulcrum, and a drive mechanism connected to the locking actuator. This invention's fulcrum locking device for a pre-treatment hanger for automotive body painting significantly improves the applicability of the pre-treatment hanger to multiple vehicle models while ensuring installation reliability. It enhances the flexibility of pre-treatment hanger equipment in painting workshops, eliminates the need for a vehicle model recognition system, and reduces the investment cost of platform integration and modification.

[0008] First claim:

[0009] The aforementioned patent differs from this application in that it has a locking device for the fulcrum of the pretreatment lifting device. Summary of the Invention

[0010] This invention provides a flexible sling support structure that avoids interference between multiple vehicle models on the same line, solves the problem of interference between non-vehicle-bearing support points and the currently bearing vehicle body, and solves the problem of the same support point bearing different vehicle bodies, thereby improving the flexibility of the support point.

[0011] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.

[0012] To solve the above-mentioned technical problems, the present invention is implemented using the following technical solution:

[0013] A flexible spreader support structure for avoiding interference between multiple vehicle models on the same line includes: a fixing assembly, a positioning groove assembly, a tilting mechanism assembly, and a load-bearing support assembly;

[0014] The fixed assembly is fastened to the lifting fulcrum arm with bolts. The positioning groove assembly is welded to the fixed assembly to ensure the Y-axis dimension. The flipping mechanism assembly is connected to the positioning groove assembly with positioning pins to realize flipping and Y-axis width adjustment. The bearing fulcrum assembly is fixedly connected to the flipping mechanism assembly with bolts.

[0015] Furthermore, the fixing assembly is composed of an X-direction limiting plate 5, a Y-direction inner fixing plate 6, a positioning fixing plate 10, a reinforcing plate 11, and a Y-direction outer fixing plate 12;

[0016] The positioning groove assembly includes a positioning groove plate 7;

[0017] The flipping mechanism assembly consists of a flipping beam 4, a flipping shaft 8, and a flipping limit stop 9;

[0018] The load-bearing support assembly consists of a polyurethane support block 1, a support block pad 2, and a support block connecting plate 3.

[0019] Furthermore, the X-direction limiting plate 5 and the Y-direction inner fixing plate 6 are connected by welding after machining, and this part is used as a component for subsequent installation.

[0020] Furthermore, the Y-direction outward fixing plate 12 is welded perpendicularly to the surface of the reinforcing plate 11, and the positioning fixing plate 10 is simultaneously welded perpendicularly to the reinforcing plate 11 and the Y-direction outward fixing plate 12. The positioning groove plate 7 is fixed to the positioning fixing plate 10 by welding, with its surface perpendicular to the positioning fixing plate 10. The flipping limit stop 9 is fixed to the positioning fixing plate by welding and passes through the structural surface. This part serves as the second assembly.

[0021] Furthermore, assembly one and assembly two are fixed to the inside and outside of the Y-direction of the rectangular tube beam of the lifting device by long bolts.

[0022] Furthermore, the support block connecting plate 3 is fixedly connected to the flip beam 4 by welding, the flip shaft 8 is fixed to the flip beam 4 through shaft hole fitting, and the end face is fixed with cotter pin to prevent the shaft from falling off. The polyurethane support block 1 and the support block pad 2 are fixed to the support block connecting plate 3 by bolt connection.

[0023] Furthermore, by manually lifting the fulcrum of the spreader and rotating it around the flip axis to 90°, the fulcrum is pulled in the Y direction to the positioning slot of other vehicle models and placed back in its original position. This allows the spreader fulcrum to switch to different widths in the Y direction to support different vehicle models. The spacing of the positioning slots is optimized according to the actual required dimensions to meet the needs of different vehicle models. By manually lifting the fulcrum of the spreader and rotating it around the flip axis to 180°, interference between the fulcrum and other vehicle models can be avoided.

[0024] Furthermore, a positioning groove is provided on the positioning groove plate 7.

[0025] Furthermore, two positioning slot plates are provided.

[0026] Furthermore, two reinforcing plates 11 are provided.
