Embodiment Construction

[0030] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0031] Such as figure 1 with figure 2 As shown, a flexible crawling climbing robot 100 provided by an embodiment of the present invention includes two guiding assemblies 1 , two open clamping assemblies 2 , a main spring 3 and a driving assembly 4 .

[0032] The two open clamping components 2 are arranged at intervals along the axial direction of the cable 50, and can be opened and closed along the radial direction of the cable 50, so that the open clamping components 2 can clamp different diameters. The cable has a large diameter change range; and at any time, at least one open clamping assembl...

Abstract

The invention is applicable to the field of climbing robots, and provides a flexible creep climbing robot. The robot comprises two guiding assemblies, two open clamping assemblies, main springs and driving assemblies; the two open clamping assemblies clamp a cable and can make open and close movement in the radial direction of the cable; the two guiding assemblies are mounted at the two opposite outer sides of the two open clamping assemblies respectively, always clamp the outer edge of the cable and can be elastically retracted in the radial direction of the cable; each main spring is connected to the two opposite inner sides of the two open clamping assemblies, one end of each main spring is fixedly connected with one open clamping assembly, the other end of each main spring is in screwconnection with the corresponding driving assembly, the driving assemblies are fixed on the other open clamping assembly and drive the main springs to rotate, and the main springs are correspondinglyelongated or shortened along with the rotation of the driving assemblies. The robot can adapt to cables different in diameter, can easily cope with the environment of the cable with a curvature and ishigh in environmental adaptability.

Description

technical field [0001] The invention belongs to the field of climbing robots, in particular to a flexible peristaltic climbing 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 c...
