Problems solved by technology

[0003] At present, there are four-wheel and six-wheel climbing and walking devices, which have poor reliability and stability during the climbing process. When the four-wheel climbing is at high altitude, it is easy to appear deviation and get stuck on the cable. Anti-deflection wheels, but when the robot deflects, the driving torque of the robot is insufficient
Although the six-wheel type is more stable, it is driven by three motors. Since the three motors are difficult to synchronize, the climbing device often has a spiral movement, and even gets stuck on the cable, which cannot be reliably detected.

Abstract

The invention relates to a regulable climbing device with a deviation prevention function for detecting a defect of a bridge guy cable. The regulable climbing device comprises a body frame, a regulable pressing component, a regulable deviation prevention component, a gravitational potential energy consumption component and a driving and braking component, wherein the body frame is a cuboid and consists of a fixing frame and a regulable frame, and the fixing frame and the regulable frame which are connected through bolts; the regulable pressing component comprises the regulable frame, sliding blocks, regulating screw rods, compression springs and pressing nuts; the regulable deviation prevention component comprises deviation prevention rods, deviation prevention frames, deviation prevention wheels, stretching springs and extension springs; the gravitational potential energy depletion component comprises a one-way clutch, a crank, a connecting rod and an air cylinder; the driving and braking component comprises a direct current motor, a bevel gear pair and an electromagnetic brake. The regulable climbing device disclosed by the invention can climb along the bridge guy cable and detect the defect, the regulable climbing device with the deviation prevention function can be suitable for bridge guy cables with different diameters and provide accurate information of the quality and the defects of the guy cable for maintaining a bridge, so that the safe operation of the bridge is ensured, and larger social and economic benefits can be created.

Description

technical field [0001] The invention relates to a device for detecting defects of bridge cables, in particular to an adjustable climbing device with anti-deviation function for detecting defects of bridge cables, belonging to the technical field of robots. Background technique [0002] Cable-stayed bridge is a new type of bridge that has emerged in the past 40 years. Because of its large span and good economic performance, it has been widely used in countries all over the world. The cable is one of the main structural parts of the cable-stayed bridge, and the quality of the cable is related to the service life of the entire cable-stayed bridge and the safety performance of the bridge. The cable defect detection robot is an intelligent mechanical device that can automatically crawl along the cable and stay at any position on the cable to detect the surface and internal defects of the cable. A safe, reliable and stable climbing device is the basis of a bridge cable defect det...
