[0029] Specifically, the movable block 202 is provided with a third through hole 206, and the movable block 202 is slidably sleeved on the fixed rod 302 through the third through hole 206.

[0030] Specifically, the linkage assembly 3 further comprises a connecting block 301, two fixed sheets 303 and two first springs 304, the fixed rod 302 is fixedly installed in the connecting block 301, the two fixed sheets 303 are fixedly installed at the two ends of the fixed rod 302 respectively, one end of the two first springs 304 is fixedly installed at one end of the two fixed sheets 303 respectively, and the other end of the two first springs 304 is fixedly connected with the two movable blocks 202 respectively.

[0031] Specifically, the second clamping assembly 7 further comprises two sliding rods 701, three second springs 704 and a friction pad 705, two arc-shaped grooves 6 are formed between the two sides of the hook body 1, the two sliding rods 701 are slidably installed in the two arc-shaped grooves 6 respectively, and the sliding rod 701 is fixedly installed between the two rotating plates 201, a strip-shaped groove 8 is formed in the hook body 1, the sliding plate 702 is slidably installed in the strip-shaped groove 8, three circular grooves 703 are formed in the top of the sliding plate 702, the three second springs 704 are fixedly installed in the three circular grooves 703 respectively, and the three second springs 704 are fixedly connected with the inner wall of the top of the strip-shaped groove 8, the friction pad 705 is fixedly installed at the bottom of the sliding plate 702, and the friction pad 705 is made of rubber.

[0032] In the embodiment, it should be noted that in the initial state, the three second springs 704 exert an upward pulling force on the sliding plate 702, so that the sliding plate 702 is at rest in the strip-shaped groove 8, and when the four rotating plates 201 rotate, the two sliding rods 701 will slide downward in the arc-shaped grooves 6, and the downward sliding of the two sliding rods 701 will press the sliding plate 702 and the friction pad 705 to slide downward in the strip-shaped groove 8 and finally contact the outer wall of the pipeline, thereby further improving the stability of the hoisting.

[0033] Specifically, the rotating plate 201 is provided with several locking teeth 205.

[0034] In this embodiment, when the cleat 205 contacts the outer wall of the pipe, it can increase the friction between the rotating plate 201 and the pipe, thereby increasing the friction between the hook body 1 and the pipe.

[0035] Specifically, the connecting block 301 has a hoisting hole 305.

[0036] In this embodiment, the connecting block 301 can be easily connected to the shackle of the crane through the lifting hole 305.

[0037] Working Principle: During use, the hook body 1 is installed at both ends of the pipe to be lifted. Then, the two shackles of the crane are installed in the two connecting blocks 301 through the lifting holes 305. Shackles are a commonly used connecting tool in lifting operations. The crane is then started. The two connecting blocks 301 are initially lifted and slide upwards. This upward sliding of the connecting blocks 301 drives the two movable blocks 202 upwards via the fixed rod 302. The upward sliding of the two movable blocks 202 then drives the four rotating plates 201 upwards via the four second bolts 5. The upward sliding of the four rotating plates 201 then drives the hook body 1 upwards via the four first bolts 4. When the hook body 1 slides upwards to contact the inner wall of the pipe, the upward sliding of the connecting blocks 301 and the two movable blocks 202 causes the four rotating plates 201 to rotate around the first bolts 4, thereby causing the locking teeth 205 on the four rotating plates 201 to rotate and contact the outer wall of the pipe. This increases the friction between the hook body 1 and the pipe, improving the stability of the lifting operation. The rotation of the rotating plate 201 also causes the two sliding rods 701 to slide downwards within the arc-shaped groove 6. The downward sliding of the two sliding rods 701 presses down on the sliding plate 702 and friction pad 705 within the strip groove 8, eventually contacting the outer wall of the pipe, further improving the stability of the hoisting. The downward sliding of the sliding plate 702 also stretches the three second springs 704. When the four rotating plates 201 rotate, the two movable blocks 202 slide away from each other on the fixed rod 302 as the rotating plates 201 rotate, compressing the two first... After hoisting is completed, the connecting block 301, the two movable blocks 202, and the four rotating plates 201 are no longer under tension. The two first springs 304 will release and push the two movable blocks 202 to reset, which in turn will drive the four rotating plates 201 to reset. The reset of the four rotating plates 201 will also drive the two sliding rods 701 to reset. When the sliding rods 701 reset, the three second springs 704 will contract and pull the sliding plates 702 to reset. During hoisting, the operator does not need to repeatedly operate the hook body 1, saving time and effort.

[0038] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from its technical solution shall still fall within the protection scope of this utility model.
