Problems solved by technology

[0003] The purpose of the present invention is to provide a device for replacing the main cable clamp of a suspension bridge and its installation method. Combining with the structural characteristics of the suspension bridge, the hanger is used as the construction platform to replace the cable clamp instead of the traditional method of erecting a full-height bracket from above the bridge deck. Solve the problems of long construction period, high cost, slow progress, large installation work surface and high work intensity for the replacement of main cable clamps

Abstract

The invention discloses a device for replacing a main cable clip of a suspension bridge and a mounting method of the device. The device comprises temporary hoops, rubber pads, a hanging bracket, steelwire ropes and lug plates, wherein the hanging bracket is formed by splicing a plurality of sections, and the temporary hoops are arranged on the two sides of the main cable clip respectively and aredetachably connected with a main cable; the rubber pads are arranged between the temporary hoops and the main cable, the lug plates are connected with the lower portions of the temporary hoops, one end of each steel wire rope is connected with the corresponding lug plate, and the other end of each steel wire rope is connected with the hanging bracket. The section type spliced hanging bracket serves as a construction platform, and the lower space of the main cable of the suspension bridge is effectively utilized; the temporary hoops anchored on the main cable serve as counter force fulcrums, the structure is light, the construction cost is low, installation is convenient, standardized construction is facilitated, the construction period is short, and the influence on the stress of the structure is small.

Description

technical field [0001] The invention relates to the technical field of detection and maintenance of suspension bridges, in particular to a device for replacing main cable clamps of suspension bridges and an installation method thereof. Background technique [0002] At present, most of the operating platforms below the main cable used for the replacement of the main cable clamps of the suspension bridge adopt the method of erecting a full support from above the bridge deck, such as Chinese patent CN105887701A, which provides a method for dismantling and replacing the upper structure of a suspension bridge, including the following steps: a .Set up a trestle bridge parallel to it on the outside of the suspension bridge, and connect the two ends of the trestle bridge with the approach bridges at both ends of the corresponding suspension bridge; b. Check the anchorages at both ends of the suspension bridge to make sure they are in normal working condition; c. Remove the original s...
