The lifting mechanism 12 is a lifting mechanism 12 that is slidably connected to the lifting platform 1.

[0033] In this embodiment, when the device is used to hook and transport goods, the driving mechanism 6 can be started, and the driving mechanism 6 is composed of a motor and a bidirectional screw rod. The two connecting blocks 15 can be controlled by the drive of the motor to gather or disperse on the bidirectional screw rod to control the movement of the No. 1 telescopic plate 13 and the No. 2 telescopic plate 14. By controlling the No. 1 telescopic plate 13 and the No. 2 telescopic plate 14 to disperse from each other, the positions of the hooks 11 on all sides can be adjusted so that the hooks 11 can be moved to a position suitable for hooking. Then, the four hooks 11 can be used to hook the goods on all sides at the same time. By this method, four grabbing points can be set above the goods at the same time when the goods are transported. Compared with traditional hooks, the method is more stable and safe when transporting goods, and can effectively prevent the goods from rotating during movement.

[0034] Example 2, as Figures 1 to 4 As shown, the top of the four hooks 11 is rotatably connected to a rotating frame 22, one end of each of the four rotating frames 22 is fixedly connected to a counterweight 23, the other end of each of the four rotating frames 22 is fixedly connected to a limit rod 19, the inside of each of the four limit rods 19 is rotatably connected to a roller 21, the bottom of each of the two mounting frames 10 is fixedly connected to a slide rod 24, the outer surfaces of the two slide rods 24 are respectively slidably connected to one side of the four sliders 18, the middle part of one side of the two mounting frames 10 is fixedly connected to a fixed frame 8, and one side of the two fixed frames 8 is fixed It is connected to a hydraulic push rod 9, and the output ends of the two hydraulic push rods 9 are fixedly connected to a push block 16. Both sides of the two push blocks 16 are rotatably connected to push rods 17. One end of the four push rods 17 is rotatably connected to one side of four sliders 18. Both sides above the two mounting frames 10 are fixedly connected to reinforcing ribs 12. Both sides above the conveying platform 3 are fixedly connected to support rods 4. The tops of the two support rods 4 are rotatably connected to pulling springs 5. The other ends of the two pulling springs 5 ​​are rotatably connected to the tops of the two mounting blocks 7 respectively.

[0035] In this embodiment, when the positions of two adjacent hooks 11 are adjusted, the push block 16 can be pushed to move by starting the hydraulic push rod 9, and the push block 16 can drive the push rods 17 on both sides to move and expand the distance between the two sliders 18. When the carrying rope is fixed on the hook 11, the carrying rope can slide toward the inside of the hook 11, and the carrying rope will push the rotating frame 22 to rotate after contacting the limit rod 19, and lift the counterweight block 23 at one end. After the carrying rope has completely passed, the counterweight block 23 will automatically fall and force the limit rod 19 to reset, limiting the carrying rope to prevent the carrying rope from falling off the hook 11. Through this method, the device can adjust the position of the hook 11 in time according to different carrying requirements when it is being carried out, and the safety of the device is also improved through the action of the limit rod 19.

[0036] Working principle: When using the device to hook and transport goods, the driving mechanism 6 can be started, and the driving mechanism 6 is composed of a motor and a bidirectional screw rod. The two connecting blocks 15 can be controlled by the drive of the motor to gather or disperse on the bidirectional screw rod to control the movement of the No. 1 telescopic plate 13 and the No. 2 telescopic plate 14. By controlling the No. 1 telescopic plate 13 and the No. 2 telescopic plate 14 to disperse from each other, the positions of the hooks 11 on all sides can be adjusted so that the hooks 11 can be moved to a position suitable for hooking. Then, the four hooks 11 can be used to hook the goods on all sides at the same time. When the two adjacent hooks 11 are hooked, the hooks 11 can be moved to a position suitable for hooking. When the position of each hook 11 is adjusted, the push block 16 can be pushed by starting the hydraulic push rod 9, and the push block 16 can drive the push rods 17 on both sides to move and expand the distance between the two sliders 18. When the carrying rope is fixed on the hook 11, the carrying rope can slide toward the inside of the hook 11. After the carrying rope contacts the limit rod 19, it will push the rotating frame 22 to rotate and lift the counterweight block 23 at one end. After the carrying rope has completely passed, the counterweight block 23 will automatically fall and force the limit rod 19 to reset, thereby limiting the carrying rope and preventing it from falling off the hook 11.
