Suspension bridge main cable rope retracting method

Abstract

The invention relates to a coiling method of main cable of suspension bridge, substantially used to coil the cable of suspension bridge. The invention is characterized in that arranging a coiling steel disc into a combination steel disc which comprises a front cover plate (22), a back cover plate (23) and a taper drum (24). The taper drum is arranged between the front cover plate (22) and the back cover plate (23), while the back end of the taper drum is fixed with the back cover plate (23) and the front end is fixed with the front cover plate (22). When coils cable, coils the main cable on the taper drum horizontally arranged on the combination steel disc (2), and when stops coiling, first vertically arranges the combination steel disc (2), detaches the front cover plate (22), releases the cable from the taper drum, and packs without blank. The invention can sequentially arrange the cables, confirm the cable quality and realize non-blank package.

Description

technical field [0001] The invention relates to a method for receiving a main cable strand of a suspension bridge. It is mainly used for receiving the main cable strands of suspension bridges. It belongs to the technical field of bridge construction. Background technique [0002] The traditional method of receiving the main cable strands of suspension bridges is to collect the strands on steel plates whose axis is perpendicular to the direction of the strands. When erecting, the strands rolled on the steel plates are transported to the erection site and unfolded. Because in transportation and erection, cable strands are all wound on the steel plate, therefore, its packaging cost is higher, and external dimension is larger, and for the bridge of some alpine valley areas, cable strands cannot be transported to the construction site. [0003] ZL00127808.8 discloses a method for retracting and unwinding parallel steel wire strands. It is carried out on a turntable whose axis o...

AI Technical Summary

Problems solved by technology

[0004] 1. Since the reel is placed vertically, the cable strands on the reel cannot be arranged in an orderly manner during the bottom-up cable collection process, resulting in chaotic arrangement of the main cable strands of the suspension bridge. During the erection of the main cable strands, it is easy to appear Cable strand crossing, messy wire, loose wire and other phenomena affect the quality of the main cable strand of the suspension bridge

[0005] 2. During the cable collection process, the zinc layer of the cable strands will fall off due to the full weight of the cable strands on the retracted cable strands, which seriously affects the surface quality of the cable strands.
