Detection system for bridge rope

Abstract

The invention discloses a detection system for a bridge rope. The detection system comprises a snake-shaped robot, a multi-single-vision detection module, a nondestructive magnetic flux leakage testing module and a magnetostriction sensing module, wherein the multi-single-vision detection module is located at a joint part of the snake-shaped robot; the nondestructive magnetic flux leakage testing module is located in the snake-shaped robot; the magnetostriction sensing module is located on the top of the snake-shaped robot. By designing the snake-shaped robot, the detection system can adapt to various environments and finish a spatial helical motion; the detection system is high in intelligent degree and strong in controllability; by virtue of the multi-single-vision detection module, the nondestructive magnetic flux leakage testing module and the magnetostriction sensing module, the external part, the internal part and the corrosive damage of the rope can be comprehensively detected; the detection system can perform gait transition in a detection task so as to successfully cross obstacles, so that the to-and-fro frequency in the detection process of the bridge rope is reduced, and the detection efficiency is improved.

Description

technical field [0001] The invention belongs to the field of bridge detection, in particular to a detection system for bridge ropes. Background technique [0002] In bridges, suspension bridges and cable-stayed bridges are widely used due to their beautiful appearance and good earthquake resistance, and rope structures are also used in many large buildings. However, due to long-term exposure to the natural environment, the rope will inevitably be eroded by wind, sun, rain and environmental pollution. Maintenance is even more important. [0003] At present, there are mainly two methods for detecting bridge ropes at home and abroad; one is to use hydraulic or electric lifting platforms for small cable-stayed bridges; the other is to use fixed points pre-installed on the top of the tower to drag The hanging basket carries the staff for inspection. The former method has a limited scope of work; the latter method is a common form adopted by many suspension bridges and cable-st...

Problems solved by technology

[0004] The purpose of the present invention is to provide a detection system for bridge ropes, aiming at solving the problem of limited working range of detection of small cable-stayed bridges using hydraulic or electric lifting platforms, and the manual detection of workers carried out by steel wire dragging baskets. Low operating efficiency, high-altitude operations are more dangerous and vulnerable to weather problems
