As shown in fig. 1 to 3:

The utility model provides a hook device with a unhooking function for underwater use, which comprises a hook base cover 1, a lifting reset mechanism 2, a unhooking anti-falling mechanism 3, a hook 4 and a limiting shaft 5, wherein the lifting reset mechanism 2 is elastically installed on the hook base cover 1 in a sliding manner, the unhooking anti-falling mechanism 3 and the hook 4 are rotatably installed on the hook base cover 1, the lifting reset mechanism 2 is rotatably connected with the unhooking anti-falling mechanism 3, and the limiting shaft 5 is fixedly installed on the inner side of the hook base cover 1. The device has the advantages of high-efficiency resetting mechanism, reliable anti-falling design, convenient unhook operation, safety guarantee of the limiting shaft 5, compact structure, easy installation, strong adaptability, operation error reduction and the like.

The lifting reset mechanism 2 comprises a lifting upright post 21, a lifting ring 22, a limiting disc 23, a spring 24 and a connector 25, wherein the lifting upright post 21 slides through the hook base cover 1, the lifting ring 22 and the limiting disc 23 are respectively and fixedly arranged at the upper end and the lower end of the lifting upright post 21, the limiting disc 23 is elastically connected with the hook base cover 1 through the spring 24, and the connector 25 fixedly arranged below the limiting disc 23 is rotatably connected with the unhooking anti-disengaging mechanism 3. The lifting reset mechanism 2 utilizes the elasticity of the spring 24 to realize the automatic reset of the lifting upright post 21, thereby greatly improving the working efficiency.

The unhook anti-disengaging mechanism 3 comprises a mounting shaft 31, an anti-disengaging buckle 32, a driving connecting rod 33 and a pulling connecting rod 34, wherein the mounting shaft 31 is rotatably mounted on the hook base cover 1, the anti-disengaging buckle 32 is fixedly mounted on the mounting shaft 31, one end of the driving connecting rod 33 is fixedly mounted on the anti-disengaging buckle 32, and two ends of the pulling connecting rod 34 are respectively rotatably connected with the driving connecting rod 33 and the connector 25. The unhooking anti-falling mechanism 2 ensures the stability of the hook in the lifting process through the anti-falling buckle 32, thereby reducing accident risk.

Embodiment one:

Specifically, a through hole is formed in the upper top of the hook base cover 1, and allows the lifting column 21 to freely slide therethrough. So that the lifting column 21 can be moved flexibly during the lifting without being limited too much. Furthermore, an outer convex side lug is provided on the lower side of the hook base cover 1, and the main function of the outer convex side lug is to allow the mounting shaft 31 to be rotatably mounted. The mounting shaft 31 can flexibly rotate, so that the anti-falling buckle 3 is driven to perform corresponding actions.

Specifically, the upper and lower ends of the lifting upright post 21 are respectively provided with a lifting ring 22 and a limiting disc 23. The lifting ring 22 is used for being connected with lifting equipment to realize lifting operation of the equipment, and the limiting disc 23 is used for limiting the stroke of the lifting upright post 21 in the sliding process to ensure the safety of operation. Notably, the sizing of the lifting ring 22 and the limiting disc 23 on the lifting column 21 is carefully considered. They cannot pass through the through holes provided in the hook base cover 1.

The two main purposes are that firstly, the size limitation ensures that the sliding range of the lifting upright post 21 in the through hole is strictly controlled, and the situation that excessive movement or unexpected falling off possibly occurs in the lifting process is avoided, so that the safety of lifting operation is improved. Secondly, the lifting ring 22 and the limiting disc 23 cannot penetrate through the through hole, so that the lifting upright post 21 can be stably fixed on the hook base cover 1 in the lifting process, shaking or tilting cannot occur, and the stability of lifting operation is further improved.

Specifically, the anti-falling buckle 32 is composed of a mounting cylinder and a buckle body, the anti-falling buckle 32 and the driving connecting rod 33 are not flush, and an included angle is formed between the anti-falling buckle 32 and the driving connecting rod 33. Because of the included angle between the two, when the driving connecting rod 33 is acted by external force, excessive pressure can not be directly generated on the anti-falling buckle 32, so that the stability and reliability of the anti-falling buckle 32 are ensured. The included angle design enables the driving connecting rod 33 to drive the anti-falling buckle 32 to open and close more flexibly during operation, so that the operation performance of the whole unhooking hook device is improved.

In particular, the main function of the limiting shaft 5 is to allow blocking the movement of the driving link 33 and the pulling link 34 in certain situations. This design is intended to prevent the mechanism from being damaged in the event of excessive movement or anomalies, while also ensuring the safety of operation. When the hook 4 is in the locked state, the limiting shaft 5 can limit the movement range of the driving connecting rod 33 and the pulling connecting rod 34, so that the hook 4 is prevented from falling off or being damaged accidentally.

In addition, the selection of the position of the limiting shaft 5 is carefully considered. It is located below the hoisting reset mechanism 2, which means that the limit shaft 5 can function in time during the hoisting process, preventing the drive link 33 and the pull link 34 from being damaged by excessive movement, even if the hoisting column 21 is offset or swayed for some reason. Meanwhile, the limiting shaft 5 is positioned on one side of the connecting position of the driving connecting rod 33 and the pulling connecting rod 34, and the arrangement ensures that the mechanism is more stable and reliable in unhooking or hooking processes.

Embodiment two:

1. Lifting process

Is connected with lifting equipment and is connected with a lifting hook of the lifting equipment through a lifting ring 22.

Lifting operation, namely lifting the lifting equipment upwards to drive the lifting upright post 21 to slide upwards in the through hole of the hook base cover 1. At the same time, the joint 25 moves upward together with the lifting column 21 and compresses the spring 24.

And the anti-falling buckle is locked, namely, along with the rising of the lifting upright post 21, the driving connecting rod 33 drives the anti-falling buckle 32 to rotate to a locking position (the anti-falling buckle 32 is in close contact with the inner side of the hook 4) under the action of the pulling connecting rod 34, so that the hook 4 is ensured not to accidentally fall off in the lifting process.

2. Unhooking process

Unlocking, when unhooking is needed, the lifted equipment is placed on the water surface (the equipment floats on the water surface) or the river bottom (the equipment sinks), the hook 4 does not have large downward pulling force, the elastic force of the spring 24 starts to play a role, and the lifting upright post 21 is quickly pushed back to the initial position. At this time, the connector 25 and the driving link 33 also move downward, and the driving link 33 moves reversely by pulling the other end of the link 34, so as to drive the anti-release buckle 32 to unlock and release the lock on the hook 4.

Checking and preparing, namely after confirming that the hook 4 is completely released and the lifting upright 21 is reset to the initial position, preparing for the next lifting operation.

3. Safety guarantee

The limiting shaft 5 has the function of limiting the movement range of the driving connecting rod 33 and the pulling connecting rod 34 in the lifting and unhooking process, and the limiting shaft 5 prevents damage or safety accidents caused by excessive movement of the mechanism.

The device has the advantages of compact structure and easy installation, and the connection between the components is simple and clear, the installation and the maintenance are easy, and the working efficiency and the safety are improved.
