Description

Technical Field

[0001] The invention relates to the field of bridge machinery, and in particular to a pulling device for traction of a suspension bridge. Background Art

[0002] During the erection of a suspension bridge, the traction system plays an important role. The traction system is generally composed of traction cables, winches, pullers, guide wheel groups, etc., to achieve the functions of rapid crossing of long and heavy cables and equipment, erection, positioning, and auxiliary force. In the traction system, the puller is mainly used to achieve the connection between the traction cables and the pulling of the ropes. Since most suspension bridges have bridge towers, when the traction system passes through the bridge tower, the traction cable and the puller need to be turned with the help of a guide wheel group. The guide wheel group is a device that fixes multiple pulleys on a steel plate, with one side open and the other side constrained.

[0003] The pullers used in general engineering construction are mostly similar to double wedge joint connection pullers, which have some areas that need improvement, such as the connection frame and the traction rope are connected horizontally, resulting in insufficient track depth; there is only one connecting shaft for fixing the pulling rope, which is inefficient; a counterweight is set on one side of the connecting shaft, resulting in poor stress on the cantilever section; the structure is simple and easily fails due to damage to a single rod, etc. At present, the use of pullers may have certain hidden dangers.
