The middle part of the first rope body 5 is connected with the first bearing body 1 through a sliding piece. When the first load-bearing body 1 is lifted up, the first load-bearing body 1 first straightens the first rope 5, as shown in fig. 1. Since the first rope 5 can slide left and right with respect to the first load-bearing body 1. When the tensile forces applied to the two ends of the first rope body 5 by the steel framework 4 are different, the first rope body 5 can slide left and right relative to the first bearing body 1 so as to balance the tensile forces of the two ends of the first rope body 5. Until the tensile forces at the two ends of the first rope body 5 are the same, the first rope body 5 and the first bearing body 1 are relatively static. Wherein the sliding piece is a fixed pulley or a sliding hook. The first rope body 5 is a steel wire rope or a carbon fiber rope.
The limiting piece is used for limiting the first rope body 5, so that the first rope body 5 cannot slide out of the first bearing body 1, and when the first rope body 5 slides, the sliding direction of the first rope body 5 is always the axial direction of the first rope body 5. For example, the limiting member is a through groove on the first bearing body 1, the first rope 5 is disposed in the through groove, and the first rope 5 is disposed along the length direction of the through groove. For another example, the limiting piece comprises a first roller 7 with a first annular groove 8 at the edge and a second roller 9 with a second annular groove 10 at the edge, one side of the first rope body 5 is positioned in the first annular groove 8, and the other side of the first rope body 5 is positioned in the second annular groove 10.
The anti-falling piece 3 is used for preventing the first rope body 5 from falling off and injuring constructors by smashing when the first rope body 5 transports the steel framework 4. For example, the falling-off preventive piece 3 is a falling-off preventive U-shaped ring. For another example, the anti-falling member 3 is a structure in which the first rope body 5 is wound around the steel frame 4.
When the deformation-preventing sliding hoisting device for the transformer substation steel framework is used, two ends of the first rope body 5 are firstly bound and connected with the steel framework 4 through the anti-falling piece 3, and the self-balancing structure is connected with the middle part of the first rope body 5.
