[0027] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.

[0028] Please refer to Figs. 1-3 In the embodiments of the utility model, a lifting machine for disassembling scrapped motor vehicles comprises a workbench 1, a driving motor is installed inside the workbench 1, a threaded rod 2 is connected to the output end of the driving motor, a lifting rod 3 extending to the outside of the workbench 1 is sleeved on the outer wall of the threaded rod 2, and a protection mechanism 4 is arranged on the lifting rod 3.

[0029] The protection mechanism 4 comprises a protection unit and a transmission unit.

[0030] The protection unit is used for providing protection for the lifting of the automobile.

[0031] The transmission unit is used for providing thrust force for the work of the protection unit.

[0032] The protection unit comprises a fixed seat 401 and a protection block 402.

[0033] The fixed seat 401 is fixed at the top end of the lifting rod 3, and the fixed seat 401 is used for providing guidance for the vertical movement of the protection block 402.

[0034] The protection block 402 is vertically and slidably installed inside the fixed seat 401, and the protection block 402 is used for limiting and protecting the movement of the two sides of the scrapped automobile.

[0035] The transmission unit comprises a stress block 403, a positioning rod 404, a spring 405 and an abutting rod 406.

[0036] The stress block 403 is vertically and slidably installed on the outer wall of the positioning rod 404, and the stress block 403 is used for giving the abutting rod 406 extrusion thrust force for rotation.

[0037] The positioning rod 404 is fixed at the top end of the workbench 1 and extends to the inside of the stress block 403, and the positioning rod 404 is used for providing guidance for the vertical movement of the stress block 403.

[0038] The two ends of the spring 405 are respectively attached to the bottom of the force block 403 and the top of the worktable 1. The spring 405 is used to provide an upward restoring force for the force block 403 after it has been moved.

[0039] The abutment 406 is rotatably mounted on the inner wall of the fixed base 401 and extends to the outside of the fixed base 401. The abutment 406 is used to provide a pressing force for the upward movement of the protective block 402.

[0040] In this embodiment: This structure allows the workbench 1 to be moved to one side of the scrapped car, with the lifting rod 3 on the outer side of the workbench 1 positioned below the chassis of the scrapped car. At this point, the drive motor inside the workbench 1 can be activated. The drive motor's operation will cause the threaded rod 2 connected to its output end to rotate. The rotating threaded rod 2 will cause the lifting rod 3 to move vertically along the outer wall of the threaded rod 2. The vertically moving lifting rod 3 will cause the force-bearing block 403 to move upwards and contact the car chassis. After contacting the car chassis, the force-bearing block 403 continues to move along with the lifting rod 3. The force-bearing block 403 will receive a reaction force from the car chassis and move along the outer wall of the positioning rod 404. The downward movement of the force block 403, which applies pressure to the spring 405, causes the bottom support rod 406 to rotate downwards. The other end of the support rod 406 then rotates upwards, causing the protective block 402 above it to be pushed upwards from the support rod 406 and move out of the fixed base 401. This allows the protective block 402 to move to both sides of the vehicle, protecting it from lateral movement during lifting and preventing it from detaching from the lifting rod 3, thus improving safety. It should be noted that the protective block 402 is not located below the vehicle, and its movement is not affected by the vehicle itself.

[0041] Please refer to this carefully. Figs. 1-3 The fixed base 401 has a groove formed inside for the vertical movement of the protective block 402. One side of the outer wall of the protective block 402 is inclined. There are four protective blocks 402 and fixed bases 401. The four protective blocks 402 are evenly and symmetrically distributed at the top of the workbench 1. The two ends of the positioning rod 404 are distributed below the bottom of the protective block 402 and the force block 403. The abutment rod 406 is in contact with the force block 403 and the protective block 402 but is not fixed. The outer wall of the positioning rod 404 is generally T-shaped. The inner wall of the force block 403 has a hole groove formed for the vertical movement of the positioning rod 404.

[0042] In the embodiment: through the structure, after the stress block 403 no longer contacts with the automobile chassis, the stress block 403 will reset under the action of the spring 405, the reset stress block 403 no longer gives the one end of the resistance rod 406 downward extrusion force, then the protection block 402 will also return to the inside of the fixed seat 401 under the action of gravity, so that the fixed seat 401 and the stress block 403 are in the flush state again, and the lifting rod 3 is convenient to take out from the automobile chassis.

[0043] The above merely describes a preferred specific implementation of the present application, but the protection scope of the present application is not limited to this. Any person skilled in the art, according to the technical scheme and the inventive concept of the present application, can make equivalent replacement or change within the technical range disclosed by the present application, which should be covered in the protection scope of the present application.
