AI Technical Summary
The existing prefabricated building lifting devices lack flexibility and cannot adapt to building components of different sizes and shapes, which limits their applicability.
By sliding the slide sleeve along the slide groove and rotating the tightening nut, the slide sleeve is fixed to the cross bracket, thereby adjusting the lateral position of the hook on the rope; at the same time, adjust the height position of the hook by hanging rings at different heights, adapting to different Hoisting requirements for components.
Flexible lifting of building components of different sizes and shapes is realized, the applicability and efficiency of the device are improved, and the load is evenly distributed through the guide wheel, reducing stress concentration and friction.

Abstract
Description

[0001] The utility model relates to the technical field of building construction, in particular to a lifting device for assembled buildings. Background Art
[0002] Prefabricated buildings refer to buildings that transfer a large amount of on-site work in traditional construction methods to factories. Building components and accessories such as floor slabs, wall panels, stairs, balconies, etc. are processed and manufactured in factories, transported to construction sites, and assembled and installed on site through reliable connection methods. During the installation of prefabricated buildings, lifting devices are required to lift the prefabricated components and transport them to the designated location of the building.
[0003] After checking the publication number: CN217437505U, an assembled building lifting device is disclosed. This technology discloses "an assembled building lifting device, including a No. 1 connecting head, a No. 1 connecting buckle is arranged at the upper position of the No. 1 connecting head, a No. 2 connecting buckle is arranged at the bottom position of the No. 1 connecting head, a lower rectangular connecting frame is arranged at the lower position of the No. 1 connecting head, a No. 3 connecting buckle is arranged at the upper position of the lower rectangular connecting frame, a No. 4 connecting buckle is arranged at the bottom position of the lower rectangular connecting frame, and a No. 1 connecting steel rope is arranged between the No. 2 connecting buckle and the No. 3 connecting buckle" and other technical solutions, which have "through the gravity drag body and the rope storage box and other structures, the distance between each No. 2 connecting steel rope can be reasonably adjusted, and the idle No. 2 connecting steel rope can be restricted from both sides to prevent the idle No. 2 connecting steel rope from being entangled with other No. 2 connecting steel ropes in use, thereby reducing safety hazards" and other technical effects;
