Cable climbing robot

Abstract

The invention discloses a cable climbing robot, which comprises a cable holding effect, can stably climb and has a good obstacle crossing effect. The robot comprises two trolleys arranged symmetrically along the circumferential direction of a cable and clasping devices arranged on the two trolleys and used for clasping the cable, the clasping devices comprise guide rails which are respectively arranged on the front part and the rear part of the two trolleys and are parallel to each other, and the guide rails are perpendicular to the axis of the cable; two roller supports are arranged on each guide rail in a sliding mode, and a spring is arranged between each roller support and the body of each trolley along the direction of each guide rail; a roller rotating around a rotating shaft is arranged on each roller support, and the rotating shaft is obliquely arranged and is perpendicular to the axis of the cable; the rollers are supported and clamped on four points on the cable; and a driving device is arranged on at least one of the rollers.

Description

technical field [0001] The invention relates to an industrial robot, in particular to a cable climbing robot for detecting cables. Background technique [0002] The main stress-bearing components of cable-stayed bridges and suspension bridges are cables. The cables are exposed to the atmosphere for a long time and are eroded by wind, sun, rain and environmental pollution. Cable-stayed bridges have adverse effects. Therefore, the detection and maintenance of the cable is very necessary. At present, the detection and maintenance facilities of bridge cables are not perfect, and the detection and maintenance of cables are mainly done manually. For example, a commonly used method of detection and maintenance: use a winch to drag a trolley, and carry a detection sensor to detect and maintain the cable, but this method has low work efficiency. [0003] In response to these problems, some inventors have designed industrial robots for detecting and maintaining cables. For example...

Problems solved by technology

[0004] The first purpose of the present invention is to overcome the problem that the cable detection robot in the prior art has poor grasping effect, is prone to spiral climbing cables, affects stability, and has poor obstacle surmounting effects on local obstacles during the cable climbing process. Provide a cable-climbing robot that can climb steadily, has a good hug effect and has a good obstacle-surmounting effect

[0005] The second purpose of the present invention is to overcome the problem that the cable detection robot in the prior art cannot well solve the problems of the trolley slipping and reversing during the cable climbing process, and to provide a kind of trolley that can effectively solve the problem of the trolley that occurs during the cable climbing process. Slipping and backward conditions, it can also be applied to a cable climbing robot that detects cables with different diameters
