Bridge cable health detection robot

Abstract

The invention discloses a bridge cable health detection robot which comprises a driving trolley, a driven trolley, a connecting device, a guiding device and a control device; the driving trolley the driven trolley are opposite and connected by the connecting device, and wheels of the two trolleys clamp a bridge cable; the driving trolley pulls the driven trolley to move by the guiding device; andthe control device is arranged on the driving trolley. The bridge cable health detection robot has the advantages of compact structure, small volume, light weight, simple and convenient manipulation,flexible movement and strong carrying load capability, can carry different types of detection and maintenance equipments and realize unmanned detection and coating for stay cables with great length, and has wide application range.

Description

A bridge cable health detection robot technical field The invention relates to a cable detection technology, in particular to a bridge cable health detection robot. Background technique The cable is the main load-bearing part of the cable-stayed bridge, and its construction cost accounts for about 25% to 30% of the total bridge construction cost. In order to reduce the maintenance cost of the cable, avoid single or all cables being corroded and replace the cable, and improve the image of the bridge, regular Internal and external inspection, painting or restoration are all required. At present, the inspection and maintenance methods for the stay cables are relatively backward, and the construction personnel generally still need to do the work by themselves at the high altitude of the bridge deck exposed to wind, rain and sun. About 1970, Germany began to use electromagnetic equipment capable of simultaneously inspecting local defects and measuring the reduction of the meta...

Problems solved by technology

After the Shanghai Xupu Bridge was completed, manual painting was adopted, that is, fixed pulley lifting points were set up on the top of the tower, and the trolley and the hanging basket carrying people and paint were driven by a hoist through a steel wire rope, and all cables were painted at high altitude by people. But the efficiency is low, and the security is poor, and the cost is high
