[0002] During the construction of steel structure buildings, the installation of cross beams needs to be completed with the help of hoisting equipment. Existing hoisting steel structures mostly use bolt locking mechanisms for fixation, with a cumbersome fixation method and difficult disassembly; a steel structure hoisting device disclosed in the publication number CN220011859U drives gears and racks through a motor to drive C-shaped clamps on both sides to move towards the middle to clamp the steel structure, and can achieve quick fixation and disassembly. However, this solution has the following drawbacks: 1. Driving through a motor greatly increases the production cost of the equipment, with poor practicability, and the demand for electricity limits the use environment; 2. Except for the clamps on both sides, this device has no other fixation means, and the clamping method of the clamps is not reliable, and it is easy to fall off during the clamping process of the steel structure, posing a safety hazard; 3. The clamps use a swinging method to clamp the steel structure, resulting in a line contact between the clamps and the steel structure, causing stress concentration at the contact points between the clamps and the steel structure and affecting the service life of the clamps.

[0018] Depend on Figures 1 to 4Given that, the utility model includes a U-shaped block 1 with an opening facing downwards. A through hole 2 penetrating the upper and lower end faces is provided in the middle of the U-shaped block 1. A U-shaped rod 3 with an opening facing downwards is arranged in the through hole 2. The U-shaped rod 3 can slide up and down along the through hole 2. A hanging ring 4 is fixedly connected to the upper side of the U-shaped rod 3 through a tension spring. Through grooves 5 penetrating the left and right end faces are respectively provided on the left and right sides of the lower end of the U-shaped block 1. A slider 6 is arranged in each through groove 5. Upper and lower clamping plates 7 are respectively fixed to the adjacent end faces of the two sliders 6. A vertical rod 8 capable of sliding up and down is arranged in the middle of the through hole 2. When the U-shaped rod 3 moves upwards relative to the U-shaped block 1, the sliders 6 on the left and right sides can be made to move towards the middle, and at the same time, the vertical rod 8 moves downwards.

[0019] A threading ring 9 is respectively fixed to the outer end of each of the sliders 6. A steel strand 10 is arranged below the hanging ring 4. A hook is provided at the end of the steel strand 10. The steel strand 10 bypasses the left and right sides and the lower side of the U-shaped block 1, passes through the threading rings 9 on the left and right sides, and then the end is connected to the hanging ring 4 through the hook.

[0020] A positioning wheel 11 is respectively rotatably connected above the sliders 6 at the left and right ends of the U-shaped block 1. The left and right ends of the steel strand 10 respectively bypass the positioning wheels 11.

[0021] A horizontal front and rear placed rotating shaft 12 is respectively arranged on the left and right sides of the vertical rod 8 in the through hole 2. The front and rear ends of the rotating shaft 12 are respectively rotatably connected to the U-shaped block 1. A gear 13 is fixed in the middle of the rotating shaft 12. Vertical first racks 14 are respectively arranged on the inner side surfaces of the vertical rod parts of the U-shaped rod 3. Vertical second racks 15 are respectively arranged on the left and right end faces of the vertical rod 8. The first racks 14 and the second racks 15 are both engaged with the corresponding side gears 13.

[0022] A limiting hole 16 penetrating the upper and lower end faces is provided in the middle of the U-shaped rod 3. A vertical limiting rod 17 is fixed to the lower end of the hanging ring 4. The limiting rod 17 penetrates the limiting hole 16 and can vertically move up and down along the limiting hole 16.

[0023] When the utility model is in use, firstly, the end of the steel beam to be hoisted is passed through the steel strand 10 through the lower side of the U-shaped block 1, so that the wing plate of the steel beam is located between the clamping plates 7, and then the slider 6 is moved horizontally to place the clamping plates 7 on both sides of the wing plate; then the lifting ring 4 is hung on the hook of the lifting equipment, and the lifting equipment is started to drive the lifting ring 4 to lift upward. During the upward movement of the lifting ring 4, the steel beam wing plate is clamped between the clamping plates 7, so that the slider 6 and the U-shaped block 1 cannot move synchronously with the lifting ring 4, the steel strand 10 is tightened upward, and at the same time, the sliders 6 on the left and right sides are squeezed inwardly to clamp the steel beam through the threading ring 9, and the lifting ring 4 pulls the U-shaped rod 3 to move upward along the through hole 2 through the tension spring, and the U-shaped rod 3 drives the gear 13 to rotate through the first rack 14, and the gear 13 drives the vertical rod 8 vertically through the second rack 15. The lifting hook 4 can be tightened upward until the tension spring is stretched to the limit, and the lifting hook 4 can drive the steel beam to move upward through the tension spring to achieve lifting. When the steel beam is lifted to the fixed position and the steel beam is fixed, it is only necessary to release the hook downward to make the lifting hook move downward, the tension spring is reset, and the U-shaped rod 3 is reset downward under the action of gravity. The vertical rod 8 is lifted upward to release the limit on the steel beam, and the steel strand 10 is relaxed and no longer squeezes the slider 6 inward. The slider 6 is manually pulled outward, and finally the fixing buckle between the upper end of the steel strand 10 and the lifting hook 4 is opened to complete the separation of the device from the steel beam.

[0024] The utility model arranges tooling between the hook and the steel beam, and utilizes the slider 6 and the clamping plate 7 that move left and right to clamp the steel beam wing plate, so that when the lifting ring 4 moves upward relative to the U-shaped block 1, the slider 6 can be squeezed inwardly by the pull rope, and at the same time, the vertical rod 8 opposite to the moving direction of the U-shaped rod 3 is used to support the upper end surface of the steel beam to achieve further positioning, and finally the bottom of the steel beam is pulled by the steel strand 10, which can share the force of the slider 6 and provide a safety to the steel beam at the same time, avoiding safety hazards caused by the steel beam slipping.
