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.

Embodiment Construction
[0020] see figure 1 , figure 1 For the present invention adopts a kind of main cable unit of suspension bridge, mainly is made up of support 1, combined steel plate 2, transmission center shaft 3, large pinion shaft 4, dial pin 5, pinion 6 and motor 7. The transmission center shaft 3 is horizontally installed on the bracket 1, and the combined steel plate 2 is set on the transmission center shaft 3; the output end of the motor 7 is connected with the pinion 6, and the pinion 6 meshes with the bull gear 4, and the bull gear 4 is fixedly connected to the transmission center shaft 3, one end of the dial pin 5 is installed inside the gear wheel 4, and the other end is inserted into the combined steel plate 2.
[0021] see Figure 2~3 , the combined steel plate 2 is mainly composed of anchor bolts 21 , front cover plate 22 , rear cover plate 23 , arc plate 24 , isolation column 25 and latch 26 . Described arc-shaped plate 24 has several sheets (there are 6 among the figure), is ...

A wind-up method for the main cable used for suspension bridge features that its reel is a combined one, which is composed of a front end cover, a back end cover, and several horizontal arc plates between said front and back end covers and with one front end fixed to said front end cover and one back end hinged to said back end cover. There is a gap between adjacent two arc plates. After said main cable is fully wound, the front end cover is detached and the arc plates are gathered up to become a conic shape, so unloading the wound cable easily.
Description
technical field [0001] The invention relates to a novel method for retracting main cable strands 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 ...
