Description

Technical Field

[0001] This utility model relates to the field of automobile dismantling technology, and in particular to a flipping device for dismantling waste automobiles. Background Technology

[0002] The tipping device for scrap car dismantling is a key piece of equipment on the dismantling production line. It is used to safely and efficiently rotate the whole vehicle or large dismantled parts to a suitable working angle so that operators can easily access the chassis, top or side to carry out dismantling operations. This greatly improves dismantling efficiency, reduces labor intensity and ensures operational safety.

[0003] Chinese Patent No. CN219156411U discloses a scrap car lifting device, including a base, a crossbeam, a drive shaft, and clamping claws mounted on the drive shaft. One end of the crossbeam is rotatably connected to the base, and the other end of the crossbeam is rotatably connected to the drive shaft. A first hydraulic cylinder is disposed between the base and the crossbeam; a second hydraulic cylinder is disposed between the base and the drive shaft. Using this technical solution, the clamping claws are used to hold the scrap car, the extension and retraction of the first hydraulic cylinder can adjust the angle between the crossbeam and the base for lifting the scrap car, and the extension and retraction of the first hydraulic cylinder can adjust the rotation angle of the drive shaft for adjusting the tilting angle of the scrap car. This device can meet the lifting and tilting requirements during the scrap car dismantling process, and the clamping claws can actively hold the scrap car, greatly improving the dismantling efficiency of scrap cars.

[0004] However, the above technical solution has the following shortcomings: When the device clamps the top of the car, it uses the curved protruding part of the claw plate end for clamping. This method not only has poor adaptability of the claw plate and a small contact area with the car, but also results in uneven force distribution on the car, which requires a very large driving power and is also prone to damaging components. Utility Model Content

[0005] The purpose of this invention is to address the problems existing in the background technology by proposing a flipping device for dismantling scrap cars, which improves the clamping effect on the vehicle roof, enhances the uniformity and adaptability of the clamping force, and ensures stability during flipping.

[0006] The present invention provides a tipping device for dismantling scrap cars, comprising a fixed frame and a pressing device. A rotating frame is mounted on the fixed frame, a connecting shaft is rotatably connected to the rotating frame, and a mounting frame is mounted on the connecting shaft. The pressing device includes a first hydraulic cylinder mounted on the mounting frame, a lifting seat driven and connected to the first hydraulic cylinder, a central pressure plate mounted on the lifting seat, four supports arranged in a circular array, a mounting block mounted on the supports, a fixing plate mounted on the mounting block, a first connecting block mounted on the fixing plate, a second connecting block rotatably connected to the first connecting block, a trapezoidal pressure block with an inclined surface structure mounted on the second connecting block, multiple arc-shaped sliding rods mounted on the pressure blocks, a limiting plate mounted on the arc-shaped sliding rods, and a buffer pad mounted on the pressure blocks and the central pressure plate. The limiting plate is located above the fixing plate.

[0007] Preferably, two symmetrically distributed crossbars are provided on the connecting shaft.

[0008] Preferably, two second hydraulic cylinders are movably connected to the fixed frame, and the second hydraulic cylinders are movably connected to the rotating frame; a third hydraulic cylinder is movably connected to the rotating frame, and the third hydraulic cylinder is movably connected to the mounting frame.

[0009] Preferably, the lifting seat is provided with two guide rods, which are slidably connected to the mounting frame.

[0010] Preferably, a reinforcing rod is provided on the bracket, and the other end of the reinforcing rod is provided on the lifting seat.

[0011] Preferably, the mounting block is provided with a positioning plate, and multiple bolts are provided through the positioning plate. The bracket is provided with multiple linearly distributed threaded holes for bolt thread connection.

[0012] Preferably, the mounting block is provided with two support sliders, and the bracket is provided with a groove for the support sliders to slide.

[0013] Compared with the prior art, the present invention has the following beneficial technical effects: This utility model uses a clamping device to press and fix the center and surrounding areas of the roof, improving the uniformity of force distribution. The adjustable pressing angle of the clamping block allows it to adapt to the curvature of the roof. Combined with the buffer pad, it improves the contact effect between the clamping block and the roof, reduces damage to components, and improves the stability of the rollover, making it highly practical.

[0015] Example 1, as Figure 1 - Figure 4 As shown in the figure, the present embodiment proposes a turning device for dismantling waste cars, including a fixed frame 1 and a clamping device; a rotating frame 2 is provided on the fixed frame 1, a connecting shaft 3 is rotatably connected to the rotating frame 2, and a mounting frame 5 is provided on the connecting shaft 3.

[0016] The clamping device includes a first hydraulic cylinder 6 mounted on the mounting frame 5, a lifting seat 7 driven and connected to the first hydraulic cylinder 6, a central pressure plate 8 mounted on the lifting seat 7 and four brackets 9 arranged in a circular array, a mounting block 10 mounted on the brackets 9, a fixing plate 11 mounted on the mounting block 10, a first connecting block 12 mounted on the fixing plate 11, a second connecting block 13 rotatably connected to the first connecting block 12, a trapezoidal pressure block 14 with an inclined structure mounted on the second connecting block 13, multiple arc-shaped sliding rods 15 mounted on the pressure blocks 14, a limiting plate 16 mounted on the arc-shaped sliding rods 15, and a buffer pad 17 mounted on the pressure blocks 14 and the central pressure plate 8. The limiting plate 16 is located above the fixing plate 11. Two guide rods 22 are mounted on the lifting seat 7 and are slidably connected to the mounting frame 5.

[0017] In this embodiment, when it is necessary to fix and flip the waste for dismantling, the vehicle is first transported to the crossbar 4 by a crane or forklift. Then, the first hydraulic cylinder 6 is activated to drive the lifting seat 7 to descend. The lifting seat 7 drives the central pressure plate 8 and the bracket 9 to descend, so that the central pressure plate 8 is pressed tightly against the center position of the top of the vehicle. At the same time, after the trapezoidal pressure block 14 on the bracket 9 contacts the perimeter of the vehicle roof, due to the arc design of the edge of the vehicle roof, the pressure block 14 rotates slightly through the axis center line connected by the first connecting block 12 and the second connecting block 13 as the center of rotation when it is pressed against the vehicle roof. The deflection and the simultaneous arc-shaped slide bar 15 guide and stabilize the rotation of the pressure block 14. The buffer pad 17 not only buffers the pressure during contact and reduces damage to the components, but also, through its excellent anti-slip and elastic compensation properties, allows the pressure block 14 to better conform to the curved surface of the roof, increasing friction and thus improving stability during subsequent flipping. The limiting plate 16 restricts the position of the pressure block 14 when not in use, preventing it from hanging down naturally and ensuring the normal use of the equipment, thus demonstrating good practicality.

[0018] Example 2, as Figure 2 - Figure 4 As shown, this embodiment proposes a tipping device for dismantling waste cars. Compared with the first embodiment, in this embodiment, the mounting block 10 is provided with a positioning plate 18, and multiple bolts 20 are provided through the positioning plate 18. The bracket 9 is provided with multiple linearly distributed threaded holes for the bolts 20 to be threaded together. The mounting block 10 is provided with two support sliders 19. The bracket 9 is provided with a sliding groove for the support sliders 19 to slide. The bracket 9 is provided with a reinforcing rod 21, and the other end of the reinforcing rod 21 is provided on the lifting seat 7.

[0019] In this embodiment, the position of the pressure block 14 can be adjusted by the positioning plate 18, bolt 20 and threaded hole so as to clamp vehicles with different roof sizes. The support slider 19 is used to provide guidance and support, and the reinforcing rod 21 is used to improve the structural strength of the bracket 9 and can be installed in multiple quantities.

[0020] Example 3, as Figure 1 As shown, the present embodiment proposes a tipping device for dismantling waste cars. Compared with the first embodiment, in this embodiment, two second hydraulic cylinders 23 are movably connected to the fixed frame 1, and the second hydraulic cylinders 23 are movably connected to the rotating frame 2; a third hydraulic cylinder 24 is movably connected to the rotating frame 2, and the third hydraulic cylinder 24 is movably connected to the mounting frame 5; and two symmetrically distributed crossbars 4 are provided on the connecting shaft 3.

[0021] In this embodiment, when flipping, the second hydraulic cylinder 23 is first activated to drive the piston rod to extend, and then the universal joint applies a thrust to the rotating frame 2, causing the second hydraulic cylinder 23 to push the rotating frame 2 to rotate around the axis of the connection point between the fixed frame 1 and the rotating frame 2. Then the rotating frame 2 drives the connecting shaft 3 to rotate, causing the connecting shaft 3 to drive the vehicle to rotate. Furthermore, the third hydraulic cylinder 24 can push the bottom of the mounting frame 5, causing the connecting shaft 3 to rotate around its own axis centerline, so as to flip the vehicle over a larger range, so that the staff can disassemble the vehicle.

[0022] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
