[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] like Figure 1-2 As shown, a large shackle pin and lifting lug insertion and withdrawal device includes a base 1, a lifting assembly, a top plate 2, a pin pushing assembly, and a pin placing assembly; the upper end of the base 1 is connected to the lifting assembly, the upper end of the lifting assembly is connected to the top plate 2, the pin pushing assembly is arranged on the left side of the upper end face of the top plate 2, and the pin placing assembly is arranged on the right side; wherein, the pin on the pin placing assembly is pushed into the lifting lug by the pin pushing assembly.

[0020] Specifically, the pin-driven assembly includes a pin-driven actuator 3, which is disposed on the upper end face of the top plate 2. It also includes a mounting bracket 7, which is connected to the upper end face of the top plate 2 and has its upper end connected to the pin-driven actuator 3. The pin-driven actuator 3 can be a hydraulic cylinder or a pneumatic cylinder.

[0021] Specifically, the pin placement assembly includes a second bracket 4 and a pin tray 5. The second bracket 4 is connected to the right side of the upper surface of the top plate 2, and the upper end of the second bracket 4 is connected to the pin tray 5 for placing the pin. The upper surface of the pin tray 5 is V-shaped to facilitate pin placement. The output end of the pin pusher 3 is at the same height as the pin.

[0022] Specifically, the lifting assembly includes an X-shaped lifting frame 6, with its lower and upper ends connected to the base 1. The X-shaped lifting frame 6 contains a drive cylinder, which drives the X-shaped lifting frame 6 to rise and fall.

[0023] Specifically, the lower end of the base 1 is provided with a set of casters 8 for easy movement. A push handle 9 is connected to one side of the base 1.

[0024] Specifically, first, place the pin on the pin tray 5 to fix it in the left and right direction. Then, move the device to the corresponding position of the lifting lug by moving the wheel set 8 and pushing the handle 9. Then, adjust the platform height by using the X-shaped lifting frame 6 so that the height of the pin is just at the center height of the lifting lug hole. Then, fix the wheel set 8. After the height of the pin and the lifting lug hole are aligned, operate the pin pusher 3 to slowly push the pin into the lifting lug hole, thus completing the pin drilling work.
