However, the sizes of existing drive shaft hoisting devices are usually fixed, making it difficult to flexibly adjust according to the lengths and sizes of drive shafts of different types of automobiles, resulting in poor practicability and versatility, and may pose safety hazards and affect work efficiency. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a hoisting device for a drive shaft, which solves the problem that it is difficult to flexibly adjust the drive shaft hoisting device according to the lengths and sizes of drive shafts of different types of automobiles by setting an adjustment mechanism.

[0005] To solve the above technical problems, the utility model is realized through the following technical solutions:

[0006] The utility model is a hoisting device for a drive shaft, including a cross plate, and an adjustment mechanism and a clamping mechanism are arranged on the cross plate.

[0007] Further, the adjustment mechanism includes two angle adjustment components and an up-and-down adjustment component. The angle adjustment component includes fixing plates fixedly connected to the left and right sides of the cross plate. One side of the fixing plate away from the cross plate is fixedly connected with an adjustment housing. The front side of the adjustment housing is rotatably connected with a rotating shaft. The rear end of the rotating shaft extends into the interior of the adjustment housing. The rear end of the rotating shaft is fixedly connected with a turntable. The turntable is rotatably connected with the inner wall of the adjustment housing. The front end of the rotating shaft is fixedly connected with an angle adjustment rod. The bottom end of the angle adjustment rod is fixedly connected with a lifting chain one.

[0008] Further, a spring one is fixedly connected to the inner bottom wall of the adjustment housing. One end of the spring one away from the inner bottom wall of the adjustment housing is in contact with the rear end of the turntable. An annular rack one is fixedly connected to the inner top wall of the adjustment housing. An annular rack two is fixedly connected to the side of the turntable close to the annular rack one. The annular rack one and the annular rack two are meshed with each other.

[0009] Further, the up-and-down adjustment assembly includes nuts fixedly connected to the top and bottom of the cross plate respectively. A threaded rod is threadedly connected to the inner walls of the two nuts, and a second suspension chain is fixedly connected to the bottom end of the threaded rod.

[0010] Further, a suspension ring is fixedly connected to the top of the threaded rod, and a hook is fixedly connected to the bottom end of the second suspension chain.

[0011] Further, the clamping mechanism includes two shock absorption assemblies and two clamping assemblies. The shock absorption assembly includes a rectangular plate fixedly connected to the bottom end of the first suspension chain. A plurality of dampers are fixedly connected to the bottom of the rectangular plate. Springs II are sleeved on the plurality of dampers, and a U-shaped plate is fixedly connected to the bottom of the plurality of dampers.

[0012] Further, a hydraulic cylinder is fixedly connected to the inner top wall of the U-shaped plate. Two sliding rods are fixedly connected to the inner wall of the U-shaped plate.

[0014] The utility model has the following beneficial effects:

[0015] 1. By setting the adjustment mechanism, the rotating shaft is extruded. The rotating shaft extrudes the spring through the turntable, so that the first annular rack and the second annular rack are separated. On the basis of extruding the spring, the rotating shaft is rotated, thereby driving the angle adjustment rod and the first suspension chain to adjust the angle. At the same time, the height of the second suspension chain is adjusted through the cooperation of the threaded rod and the nut. Through the adjustment mechanism, the size of the hoisting device is no longer fixed, and the hoisting work of drive shafts with different lengths can be satisfied to a certain extent, enhancing the practicability and versatility of the hoisting device and greatly improving the working efficiency of the device.

[0016] 2. By setting the clamping assembly, the hydraulic cylinder is started. The output end of the hydraulic cylinder drives the corresponding slider to slide on the sliding rod. When the corresponding slider slides, it drives the corresponding connecting rod to move, thereby driving the rhombic block to rotate. When the rhombic block rotates, it drives the other connecting rod to move, thereby driving the other slider to move on the sliding rod. When the two sliders move, the corresponding two clamping blocks are driven to move away from or close to each other. Through the clamping mechanism, the fixing work of drive shafts with different diameters can be satisfied to a certain extent, and at the same time, the drive shaft can be firmly clamped, reducing the shaking and displacement of the drive shaft during hoisting, ensuring its stable position and reducing safety risks.

[0017] Of course, it is not necessary for any product implementing the present utility model to achieve all the above-mentioned advantages simultaneously. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] A specific application of this embodiment is as follows: Arrange the transmission shaft to be hoisted, rotate the threaded rod 211, and the threaded rod 211 moves up and down under the influence of the two nuts 210, thereby adjusting the second lifting chain 212. Fix the adjusted second lifting chain 212 to the middle part of the transmission shaft through the hook 214. Then, by squeezing the rotating shaft 23, the first annular rack 28 and the second annular rack 29 are separated. After the first annular rack 28 and the second annular rack 29 are separated, rotate the rotating shaft 23. When the rotating shaft 23 rotates, it drives the angle adjustment rod 25 to rotate. When the angle adjustment rod 25 rotates to an appropriate angle, stop squeezing the rotating shaft 23. The spring I 27 rebounds to form a rebounding force on the turntable 24, thereby driving the second annular rack 29 back to the starting position. At this time, the first annular rack 28 and the second annular rack 29 are re-engaged, and the rotating shaft 23 cannot rotate, thereby fixing the angle adjustment rod 25. After the angle of the angle adjustment rod 25 is adjusted, start the hydraulic cylinder 35. The output end of the hydraulic cylinder 35 pushes the corresponding slider 37 to slide on the sliding rod 36. When the corresponding sliding rod 36 slides, the rhombic block 311 is driven to rotate through the corresponding connecting rod 312. When the rhombic block 311 rotates, it drives the corresponding other connecting rod 312 to move, thereby driving the corresponding other slider 37 to move. When the two sliders 37 move, the corresponding two clamping blocks 38 are driven to move away from or close to each other, clamping and fixing both ends of the transmission shaft. The dampers 32 and the springs II 33 provide a shock-absorbing effect on the transmission shaft, reducing the impact on the transmission shaft caused by pauses or speed changes during the hoisting of the transmission shaft. After the transmission shaft is fixed, it is connected to the hoisting device through the lifting ring 213, and then the transmission shaft is hoisted.
