The reinforcement legs 2 are symmetrically arranged on the left and right ends of the running track 5, which can limit the hook 3 to prevent the hook 3 from swaying, thereby increasing the stability and safety of the lifting;

[0026] The upper end of the hook 3 is fixedly installed with a connection plate 11, and the upper end of the connection plate 11 is fixedly installed with a threaded steel column 12. The outer end of the threaded steel column 12 is threadedly connected with a nut 13, and the lower end of the nut 13 is tightly fitted with an adjustment plate 14. The upper end of the adjustment plate 14 is fixedly installed with a fixing member 16, and the rear end of the fixing member 16 is fixedly installed with a connecting rod 18, and the rear end of the connecting rod 18 is fixedly installed with a connecting member 20. The inner ends of the connecting member 20 and the connecting rod 18 are provided with a sliding groove 19. The upper end of the fixing member 16 is fixedly installed with a wire disk 17, and the front end of the connecting rod 18 is fixedly installed on the outer end of the wire disk 17. The inner end of the adjustment plate 14 is provided with a circular groove 15, and the threaded steel column 12 is slidably installed on the inner side of the circular groove 15, which is suitable for different usage conditions, and is easy to fix after the angle is adjusted to improve stability.

[0027] Specific working principle:

[0028] like Figure 1 , Figure 2 and Figure 3 As shown, when the electric hoist lifting device is used, the lifting motor 1 is moved to the position where it needs to be used under the drive of the hoist sports car 4, and then the lifting motor 1 releases the wire rope, and the hook 3 descends to the height where the lifting is required. When the hook 3 descends, the hook 3 drives the moving round rod 7 to move downward, and the left and right ends of the moving round rod 7 move downward on the inner side of the reinforcement leg 2. The ball 8 on the inner side of the moving groove 6 rotates when the moving round rod 7 moves to achieve smooth movement. The moving round rod 7 can limit and reinforce the hook 3 to prevent the hook 3 from swinging left and right, and then the required After the cargo to be hoisted is hooked by the hook 3, the lifting motor 1 retracts the wire rope, the hook 3 and the moving round rod 7 move up synchronously, and then the hoisting car 4 drives the lifting motor 1 and the hook 3 to move left or right to the position where the cargo needs to be unloaded. When the hook 3 moves left and right, the connecting rod 18 and the connecting piece 20 at the rear side of the hook 3 slide on the outer end of the moving round rod 7 through the slide groove 19. When the moving round rod 7 is not needed, the connecting piece 20 can be removed from the outer end of the connecting rod 18, and then the moving round rod 7 is moved up to the top without affecting the normal use of the hook 3.

[0029] like Figure 1 , Figure 2 and Figure 4 As shown, when the angle of the hook 3 needs to be adjusted, the nut 13 is turned upward to rotate the hook 3. When the hook 3 rotates, the threaded steel column 12 is driven to rotate on the inner side of the circular groove 15 through the connecting plate 11. The threaded steel column 12 is arranged in four groups at equal angles to achieve a better installation effect on the hook 3. After moving to the desired angle, the nut 13 is tightened downward to fix it. The above completes a series of operations of the electric hoist lifting device. The contents not described in detail in this description belong to the prior art known to professional and technical personnel in this field.
