Description

Technical Field

[0001] The utility model relates to the technical field of non-destructive testing auxiliary equipment for steel wire ropes, in particular to a straight bridge cable testing traction robot. Background Art

[0002] At present, the nondestructive testing instrument for steel wire ropes is usually not equipped with a driving structure, that is, the testing process can only be completed by external force or relative movement with the steel wire rope in a fixed state. When testing the inclined steel cables of bridges, a traction robot needs to be configured to provide traction. The traction robots in the prior art have the following shortcomings in actual use: 1. Since the motors of the traction robots are all configured on the side, the traction robots are relatively wide. When performing nondestructive testing on the steel cables arranged side by side in the horizontal direction, the surface of the traction robot will rub against the adjacent steel cables, which will not only reduce the traction force, but also may cause scratches on the surface of the lock sleeves of the adjacent steel cables; 2. The existing traction robots require external power supply, and usually need to be equipped with wires connected to the bottom surface. During the traction process, the traction robot may rotate circumferentially. This process will cause the wires to be entangled on the surface of the bridge cables, affecting the traction action, and may break the wires, causing irreversible damage to the traction robot and the nondestructive testing instrument.
