A cable-stayed bridge detection robot

Abstract

The invention discloses a detecting robot for cables of cable-stayed bridges. The detecting robot comprises a supporting plate, a first roller set, a connecting rod, a spring, a dynamic braking device and two second roller sets. The first roller set is connected with the second roller sets through the spring and the connecting rod. The first roller set comprises a first roller, wherein the first roller can rotate, and in the outer contour, the middle of the first roller is thinner than the two ends of the first roller. Each second roller set comprises two second rollers, wherein the two second rollers can rotate synchronously, and a V type included angle is formed between the two second rollers. By the adoption of the structure, the detecting robot and the cables can be conveniently disassembled or assembled in a shorter time just by one person; the descending speed of the robot can be effectively controlled within a reasonable range, and it can be guaranteed that the robot returns to the ground safely and reliably; furthermore, the robot has high adaptability to pipe diameters and obstacles, can adapt to the cables of different pipe diameters, and is wide in adjusting range and suitable for detecting flexible power transmission lines and other rod products.

Description

technical field [0001] The invention relates to a robot, in particular to a cable-stayed bridge detection robot, which is mainly used for fault detection of long-span cable-stayed bridge cables or other high-altitude poles and transmission lines. Background technique [0002] Cable-stayed bridge is a new type of bridge that has emerged in recent decades, and has been widely used in the world because of its good seismic performance and economic performance. With the rapid development of my country's traffic construction, more and more long-span bridges appear on large rivers, and cable-stayed bridges and cable-stayed bridges are widely used as extra-large economic bridges. [0003] From the early 1990s to now, the construction of cable-stayed bridges in our country has experienced a new upsurge. In 2005, with the smooth opening of the world-renowned Runyang Bridge and the official closure of China's first steel-tower cable-stayed bridge, the Third Nanjing Yangtze River Bridg...

Problems solved by technology

[0010] In the next few years, there will be a large number of cable-stayed bridges with various spans, all of which can be listed as the service objects of the cable detection robot. If all the cables will be detected by the existing method, it will take a lot of manpower and material resources
