Cable detection robot

Abstract

The invention relates to the field of detection robots, and provides a cable detection robot. The cable detection robot comprises two guiding assemblies, two open clamping assemblies and a telescopicpower source; the two open clamping assemblies are both clamped on a cable and can a performs an open and close movement in the radial direction of the cable; the two guiding assemblies are separatelymounted on two opposite outsides of the two open clamping assemblies and are always clamped on the outer edges of the cable, and the guiding assemblies can be elastically contracted in the radial direction of the cable; and the telescopic power source is connected to two opposite insides of the two open clamping assemblies, and a power output end of the telescopic power source is hinged to one ofthe open clamping assemblies, and the other end of the telescopic power source is fixedly connected with the other one of the open clamping assemblies. The cable detection robot adopts the open clamping assemblies, so that the problems of small diameter changing range and liable slippage of a wheel drive structure of a traditional closed clamping frame are solved; and meanwhile, creeping climb ofa robot is achieved through a buffer device and the telescopic power source, and the environmental adaptability of the robot is improved.

Description

technical field [0001] The invention belongs to the field of detection robots, in particular to a cable detection robot. Background technique [0002] The cable is one of the main stress-bearing components of the cable-stayed bridge and the suspension bridge. It is exposed to the air for a long time. Under the long-term action of the bridge load, rain vibration and wind vibration, the protective layer (polyethylene PE) on the cable surface is prone to hardening and aging. And other damage phenomena, the steel wire bundle inside the cable is prone to broken wires and fractures, which endangers the safety of the bridge. Therefore, the cable inspection work is very important. [0003] At present, the conventional detection method is manual inspection or detection using a cable climbing robot. The way of manual inspection is not only heavy workload, low efficiency, but also poor security. Existing cable climbing robots usually adopt a wheeled structure. When the cable is tight...
