Bridge stay cable corrosion detecting equipment

Abstract

The invention discloses bridge stay cable corrosion detecting equipment. The equipment comprises an upper connecting frame and a lower connecting frame, wherein the upper connecting frame is internally provided with a sliding seat, the sliding seat is internally provided with a threaded rod and threaded sliding blocks, the thread directions in threaded holes of the two threaded sliding blocks areopposite, the lower end of each threaded sliding block is provided with a connecting plate, each connecting plate is a semi-circular plate structure, each connecting plate is provided with an adjusting plate, the lower end of each adjusting plate is connected with a roller device, the upper end of the lower connecting frame is provided with driving wheel devices, corresponding positions of two sides of the upper connecting frame and lower connecting frame are provided with connecting through holes, the connecting through holes are internally provided with connecting threaded rods, the connecting threaded rods are in sleeved connection with shaft sleeves, the shaft sleeves are provided with mounting frames, and the mounting frames are provided with corrosion detecting probes. The bridge stay cable corrosion detecting equipment has the advantages that the structure is stable, the operation is stable, the adjustment is convenient, the equipment can be applied to stay cables with differentdiameters, the fixation is convenient, the movement along the stay cable can be realized, the corrosion detection of the stay cable is realized, the detection efficiency is high, the detection has nodead angles, and the current use requirements are met.

Description

technical field [0001] The invention relates to a detection device, in particular to a detection device for the corrosion of a bridge stay cable. Background technique [0002] Bridges generally refer to structures erected on rivers, lakes and seas to allow vehicles and pedestrians to pass smoothly. In order to adapt to the modern high-speed development of the transportation industry, bridges are also extended to buildings that cross mountain streams, poor geology or meet other transportation needs to make traffic more convenient. A bridge is generally composed of a superstructure, a substructure, a support and ancillary structures. The superstructure is also called a bridge span structure, which is the main structure for crossing obstacles; the substructure includes abutments, piers and foundations; Or the force transmission device installed at the supporting place of the bridge abutment; the auxiliary structures refer to the bridge head board, conical slope protection, ban...

AI Technical Summary

Problems solved by technology

The inspection before the cable replacement found that the PE protective layer of most of the cables was cracked and peeled off, and the steel wires were seriously corroded, which directly affected the structural safety of the bridge.

[0004] At present, the structure of the detection equipment of the cable-stayed cable is relatively simple, and it cannot be detected along the cable-stayed cable, and the detection efficiency is low, which cannot meet the current use requirements.
