[0002] With existing truck-mounted crane hook systems, if the hook swings back and forth above the cab while the crane is in motion, it can obstruct the driver's field of view and compromise driving safety. Therefore, when the crane is not in operation, the hook is typically secured with external ropes or sleepers. However, during use, it was discovered that when the crane is started or terminated, the operator must manually dismount and untie the hook, increasing workload and consuming physical effort, while also creating operational safety hazards. Furthermore, manual operation is required every time the crane is started or terminated, which is cumbersome and inefficient. Furthermore, if the hook is secured too tightly to the frame, the frame may deform during operation.

[0025] Among them, the No. 1 limit plate 3 is connected to the support frame 5 through the No. 1 guide column 11. The No. 1 guide column 11 and the support frame 5 are clearance-fitted. The No. 1 guide column 11 is sleeved with a No. 1 adjustment nut 10. The No. 1 guide column 11 plays a guiding role, and the No. 1 adjustment nut 10 plays a limiting role.
[0026] The second limiting plate 4 is connected to the fixed plate 6 through the second guide column 7. The second guide column 7 and the fixed plate 6 are fitted with a clearance. The second guide column 7 is provided with a second adjusting nut 8. The second guide column 7 plays a guiding role, and the second adjusting nut 8 plays a limiting role.
[0027] The hanger 2 is hung on the boom body 1, and a pull rod 23 is embedded in the boom body 1. One end of the pull rod 23 is fixedly connected to the wire rope 17 through a connecting sleeve 27, and the other end of the pull rod 23 is sleeved with an anti-slip nut 24, a locking nut 25 and a shock-absorbing spring 26. The locking nut 25 is arranged between the anti-slip nut 24 and the shock-absorbing spring 26. The pull rod 23 plays a role of fixed connection, the anti-slip nut 24 plays a role of anti-falling, and the shock-absorbing spring 26 plays a role of buffering.
[0028] The other end of the wire rope 17 is connected to the crane, and a movable pulley 15 and a fixed pulley 20 are wound around the wire rope 17. The movable pulley 15 is connected to the hook frame 13 through a bearing seat.

[0029] A hanging hook 9 is embedded in the hook frame 13, and a limiting nut 14 is provided at one end of the hanging hook 9. A limiting rod 16 is provided around the movable pulley 15. The limiting rod 16 is fixedly connected to the hook frame 13 to the hanging hook 9 for hanging materials. The limiting nut 14 and the limiting rod 16 both play a limiting role.
[0030] The fixed pulley 20 is connected to the fixed bracket 22 through a bearing seat. The fixed bracket 22 is fixedly connected to the boom body 1 and serves as a rotation support.
[0031] The working principle of the present invention is as follows: before use, hang the bracket 2 on the appropriate position of the boom body 1 and lock it, insert the pull rod 23 into the boom body 1, set the shock-absorbing spring 26, install the locking nut 25 and the anti-slip nut 24 in sequence, connect one end of the wire rope 17 to the crane, ensure that the power supply of the control box 21 is sufficient, start the power supply of the control box 21, and pair it with the control box 21 through the on-board control system. At this time, the control box 21 sends a pairing signal through the signal transceiver 19. When the on-board control system receives the signal, the control box 21 is paired with the control box 21. Select pairing. After the first pairing is successful, the subsequent startup will automatically connect. When the above operations are completed, you can use it. When in use, when lifting is required, the wire rope 17 is released by the crane, the hook frame 13 leaves the limit area and starts working. When storage is required, the wire rope 17 is collected by the crane, and the wire rope 17 drives the hook frame 13 to rise. When the laser sensor 18 detects that the hook frame 13 is in place, it transmits a signal to the control box 21. The control box 21 sends a stop signal through the signal transceiver 19, and the on-board system receives the signal. After the first limit plate 3 and the second limit plate 4 are released, the crane is controlled to stop retracting the wire rope 17. At this time, the hook frame 13 just reaches the set position. When the vehicle moves, the hook frame 13 cannot swing with the vehicle due to the action of the first limit plate 3 and the second limit plate 4, which reduces the impact on the driver's field of vision. At the same time, when colliding, the first buffer pad 28 and the second buffer pad 12 can effectively absorb shock, reducing the impact of the impact on the device structure. The utility model has a reasonable structural design and is easy to install and use. Through the design of the first limit plate 3, the second limit plate 4, the first buffer pad 28 and the second buffer pad 12, it can play a role of buffering protection while limiting the hook frame 13, not only reducing the impact on the driver's field of vision, but also avoiding deformation of components caused by excessive tightening of the hook frame 13. It is highly practical. Through the design of the control box 21, the laser sensor 18 and the signal transceiver 19, not only can the hook frame 13 be fixed in place for detection, but also it is convenient to realize the automatic retraction and extension of the hook frame 13, which not only reduces labor intensity, but also improves work efficiency and is more economical.
