[0023] The steel structure ceiling keel 6 is lifted as a whole. After the construction is completed, measuring instruments such as total stations and levels are required to detect the distance from the ground of each hanging point, calculate the relative height difference of each hanging point, and adjust the height of each hanging point to make the steel structure ceiling keel 6 reach the designed posture; after ensuring that all design parameters are correct, the steel structure ceiling keel 6 is lifted as a whole using a lifting device.

The sleeve 201 is connected to limit bolts 203 through the threaded holes. The limit bolts 203 are attached to the surface of the slide rail 1. The slide rail 1 slides relative to the sleeve 201, so that part of the slide rail 1 extends to the outside of the building. Then, the building materials are lifted upward, and the slide rail 1 is slid toward the inside of the building, so that the building materials can be transferred from the outside to the inside of the building. Then, the relative position of the slide rail 1 and the sleeve 201 can be fixed by screwing the limit bolts 203. In addition, baffles 101 are welded at both ends of the slide rail 1 to prevent the slide rail 1 from detaching from the sleeve 201 when sliding relative to the sleeve 201; and also to prevent the power trolley 3 from detaching from the slide rail 1 when moving along the slide rail 1.

[0026] The power trolley 3 includes a U-shaped plate 301, which is composed of two side plates and a bottom plate, and is U-shaped.

The motor 1 306 drives the drive shaft 307 to rotate, which can drive the two sets of sprocket 2 308 to rotate synchronously; with the transmission effect of the sprocket 2 308, the chain belt 309 and the sprocket 1 305, the four sets of wheels 304 are driven to rotate synchronously. Therefore, the four sets of wheels 304 roll on the slide rail 1, and the power trolley 3 can move on the slide rail 1.

[0028] The lifting drive member 4 includes a U-shaped plate 2 401 fixedly mounted at the bottom of the U-shaped plate 1 301, a motor 2 402 fixedly mounted on the right side of the U-shaped plate 2 401, a winding roller 403 fixedly mounted at the output end of the motor 2 402, the winding roller 403 rotatably connected to the inside of the U-shaped plate 2 401, a steel wire rope 404 wound on the winding roller 403, a through hole 405 is formed through the bottom of the U-shaped plate 2 401, the steel wire rope 404 passes through the through hole 405, and arc chamfers are arranged at the edges of both ends of the through hole 405. The winding roller 403 is driven to rotate by the motor 2 402 to wind up or release the steel wire rope 404, thereby driving the suspension assembly 5, the steel cable 8 and the steel structure ceiling keel 6 to rise and fall.
