Problems solved by technology

[0002] At present, there is no inspection road for the space main cable of a type of suspension bridge. In order to ensure the safety of the bridge operation process, it is necessary to carry out regular inspections on the main cable of the main load-bearing components. Manual inspection is realized near the main cable. The existing technology mainly relies on manual visual inspection, which has many shortcomings: slow work efficiency, high inspection intensity, high hidden dangers of high-altitude operations, need to occupy part of the lane and interrupt traffic, long inspection cycle, and consumption of large machinery shifts many and costly
[0004] However, the above-mentioned device still has problems when the main cable is detected, because the main cable is often not arranged in a straight line, and its projection on the surface is a curve with a certain degree of curvature. The fixture of the above-mentioned device has a rigid structure, so the clamping mechanism in the above-mentioned device cannot Applicable to the change of the plane cable shape of the main cable in space, but only to the change of the longitudinal cable shape of the main cable in space, the clamping fit is poor, and the clamping force is insufficient, which makes the stability of the detection operation poor

Abstract

The invention relates to detection of a bridge cable system, and particularly to a space main cable clamping mechanism and the self-adaptive main cable detection device. The device comprises a clamp and a supporting leg mechanism, the clamp is used for clamping a bridge main cable, and the supporting leg mechanism comprises a supporting leg body, an arc-shaped support, a reset element connected tothe upper end of the arc-shaped support, a spherical hinge with the lower portion connected with the upper end of the reset element and an elastic element with one end connected with the transverse side wall of the reset element and the other end connected with the supporting leg body; the clamp is movably connected with the supporting leg body, and the upper portion of the spherical hinge is fixedly connected with the supporting leg body. Self-adaptive longitudinal and planar cable shape changes are achieved by releasing and sliding back to the initial position through elastic deformation ofthe elastic element, self-adaptive space main cable longitudinal inclination angle and transverse inclination angle changes can be achieved for main cable surface walking, and the working stability of the detection device is improved.
