Background
The main cable of the suspension bridge is woven by dozens or hundreds of cable strands, and the most key and basic work for erecting the main cable is to complete the erection of all the cable strands. The method for erecting the cable strand commonly adopted at present is to arrange a set of traction system, wherein the traction system comprises a cable storage drum, a winch, a bogie, a guide wheel group, a portal frame, a pulley block, a traction cable and the like. Main cable strand is when erectting, and the strand is connected through dragging the puller and traction system's traction cable, through traction system operation, drags the puller to drive the strand along catwalk circuit operation and accomplish and erect, so reciprocal, accomplishes the erection of all main cable strands.
The main problem of the existing system is that when the traction system runs, a dragging device hung on a traction cable passes through a tower top saddle on a tower top door frame and a door frame saddle on a middle door frame, a shuttle pipe of the dragging device directly contacts with guide wheel groups of the tower top saddle and the door frame saddle and generates large impact, so that the traction system can only run at a low speed of less than 1m/s or about 1 m/s. For a large-span suspension bridge, the erection time corresponding to each cable strand is longer due to the longer length of the main cable; and the main cable diameter is bigger, and the corresponding internal strand quantity is also bigger. When the existing method is adopted to erect the cable strand, the time required for erecting the whole main cable is often more than several months, and the requirement of the construction period of the large-span suspension bridge cannot be met.
