Abstract

The invention discloses a system for changing a sling of a suspension bridge and a method for changing the sling of the suspension bridge, and relates to the technical field of change of the sling of the suspension bridge. The system comprises a sling clip, a towing wheel, a lifting appliance and two winches, wherein the towing wheel is arranged on the sling clip and comprises a pedestal and a plurality of rolling wheels; the rolling wheels are arranged on the pedestal; the plurality of rolling wheels are arranged along the arc-shaped path side by side to form an arc-shaped traction path; the lifting appliance is arranged above the sling clip and is used for lifting the sling to switch between the sling clip and the traction path; and the winches are connected with anchor heads arranged on two end parts of the sling correspondingly through steel wire ropes. According to the system and the method, the sling can be changed quickly and conveniently under the condition of low lifting height.

Description

technical field [0001] The invention relates to the technical field of replacement of suspension bridge cables, in particular to a suspension bridge replacement system and a method for replacing suspension bridge cables. Background technique [0002] Suspension bridge refers to a bridge in which cables (or steel chains) are suspended by towers and anchored to both banks (or both ends of the bridge) as the main load-bearing members of the superstructure. Its cable geometry is determined by the balance of forces and is generally close to a parabola. Many slings hang from the cables to hang the bridge deck. During the long-term use, various diseases will appear in the suspension bridge suspension cables, mainly including: (1) corrosion of the upper and lower anchor heads; (2) anchor loosening, failure, slipping wire; (3) inner wire Corrosion or fatigue broken wires; (4) damage, aging, cracking, and damage to the sling protective sleeve; (5) the axis of the sling is deviated, ...
