[0020] Embodiment 1: When in use, the winding mechanism 4 rotates, and the main steel rope 5 and the rotating assembly 7 are lowered, so that the steel rope fixing assembly 8 is disassembled and wrapped along the outer side of the steel structure to be lifted, so that the connecting plate 1 82 and the connecting plate 2 83 are aligned, and the mounting bolts 84 are selected, so that the steel rope fixing assembly 8 is wrapped around the outside of the steel structure, and the motor 63 on the side of the lifting seat 6 is started to drive the gear 1 64 to rotate, and drive the gear 2 72 to rotate, so that the rotating assembly 7 rotates, and drives the auxiliary steel rope 81 to rotate, and the auxiliary steel ropes 81 on both sides of the outside of the steel structure are wrapped around each other and tightened on the outside of the steel structure , then tighten the locking bolt 62 on the side, and start the electric push rod 73 to push the positioning assembly 9 down. The positioning assembly 9 moves downward and squeezes and fixes the top of the wound auxiliary steel rope 81 to complete the quick fixation. Similarly, the fixation on the other side is completed, and the winding mechanism 4 is started and lifted upward to complete the lifting.

After adjustment, the steel structure can be wound and fixed.

[0021] Firstly, by utilizing the cooperation of the steel rope fixing assembly 8, the rotating assembly 7 and the lifting seat 6, when lifting the steel structure, the auxiliary steel rope 81 is quickly wrapped around the outside of the steel structure, and during the rotation process, the auxiliary steel ropes 81 on both sides are wrapped around the top of the steel structure and self-wound to achieve the tightening of the steel structure, and the positioning assembly 9 is pushed down by the electric push rod 73 to further lock the wound auxiliary steel rope 81, and the rotating assembly 7 is locked and fixed to complete the quick winding and fixing, maintain the lifting stability, and there is no need to specifically look for the winding rope.

Moreover, the two groups of lifting seats 6 can independently lift different steel structures, and the comprehensive use effect is good.

[0023] Embodiment 2: When the auxiliary steel rope needs to be lubricated, the pressing assembly 11 is pushed so that the baffle 113 drives the push rod 112 to move and compresses the spring 114. At the same time, the push plate 111 moves and squeezes the elastic storage assembly 10, so that the elastic storage bag 101 compresses the internal lubricating oil, so that the lubricating oil passes through the injection holes on the side tube 102 and the injection plate 103, and is sprayed into the socket hole 93, and adheres to the outer surface of the auxiliary steel rope 81 to complete the lubrication.
