When constructing a steel structure building, the steel structure needs to be lifted, but the existing lifting methods are mostly through lifting belts. Due to the different lengths and widths of steel structures, it is difficult to tighten the steel structure during lifting. It is very likely that the steel structure will slip during the lifting process, which is very dangerous.

[0003] The Chinese patent with publication number CN216377185U discloses a steel structure profile hoisting device, including a hoisting plate, a cylinder symmetrically fixedly connected to the bottom of the hoisting plate, two driving ends of the cylinders fixedly connected to a connecting plate, two connecting plates respectively arranged between two support rods, the support rods slidably connected to the bottom of the hoisting plate, a clamping mechanism fixedly connected to the bottom of the support rods, a buffer mechanism fixedly connected to the inside of the clamping mechanism, the buffer mechanism can be contacted and connected to the steel structure, and a connecting assembly is arranged above the hoisting plate. The patent clamps the steel structure by the clamping mechanism, protects the steel structure by the buffer mechanism, and enhances the connection strength between the steel hook and the hoisting plate by the connecting assembly, thereby improving the safety of use.

[0004] The above technical solution drives the bidirectional screw to rotate through a driving motor to drive the movable plate, movable rod and clamping plate to move and clamp the steel structure. The support rod can be driven to move through two cylinders, thereby driving the sliding plate to move and adjust the clamping position. However, the use of motors and cylinders makes the cost of the device relatively high. Utility Model Content

The setting of the baffle 51 can support the bottom of the steel structure, thereby preventing the steel structure from falling during lifting, and the wall on one side where the two clamping plates 5 are close to each other is fixedly installed with an anti-skid pad 52, and the top wall of the baffle 51 is also fixedly installed with an anti-skid pad 52, and the setting of the anti-skid pad 52 prevents the steel structure from slipping during lifting. A roller 53 is fixedly installed on the bottom wall of the clamping plate 5. The setting of the roller 53 facilitates the movement of the lifting plate 2, and can clamp and fix steel structures of different lengths. A fixing ring 22 is fixedly installed on the top wall of the two lifting plates 2. The setting of the fixing ring 22 facilitates the crane to lift the device. After determining the size of the steel structure to be lifted, the two lifting plates 2 are slid along the direction of the fixing plate 1. After the lifting plates 2 are slid and installed in the appropriate position, the crane is used to hang the hook inside the fixing ring 22 to drive the device to move upward. In the process of the device moving upward, the two second connecting rods 41 are driven to rotate around the fixing rod 31. The rotation of the two second connecting rods 41 drives the two first connecting rods 4 to rotate, so that the two first connecting rods 4 rotate around the hinge, so that the two clamping plates 5 are close to each other, and the steel structure is clamped and fixed. It is used to adapt to the fixation of steel profiles of different lengths, has strong practicality and low cost.
