Balance clamping shock-proof device for stay cable detection robot

Abstract

The invention discloses a balance clamping shock-proof device for a stay cable detection robot. The balance clamping shock-proof device comprises a robot frame and two walking units arranged on the robot frame, and the two walking units are oppositely clamped on a stay cable. Each walking unit comprises a first force arm support which is rotatably arranged at the upper end of the robot frame; a second force arm support rotatably arranged at the lower end of the robot frame, wherein the second force arm support is provided with a rolling wheel, and the rolling wheel abuts against the stay cable; a hinge device hinged between the first force arm support and the second force arm support; and an electric push rod hinged between the first force arm support and the second force arm support . According to the balance clamping shock-proof device for the stay cable detection robot, composition accessories of the shock-proof device are simplified, so that the structure is compact; and the cable diameter variation range which can be detected is larger.

Description

technical field [0001] The invention belongs to the technical field of climbing cable mechanical equipment and facilities, and in particular relates to a balanced clamping and shock absorbing device for a cable-stayed detection robot. Background technique [0002] Cable-stayed cables are the main load-bearing parts that directly transfer the weight of the main girder and deck of the cable-stayed bridge to the tower. The cable material of the cable-stayed bridge is usually a steel cable, and the steel cable jacket is equipped with a PE sheath. The cable-stayed cable inspection robot can automatically climb up the cable-stayed cable, and check the cable-stayed cable PE sheath through the camera mounted on the robot. In recent years, with the increasing number of cable-stayed bridges built in various places, the detection of cable-stayed cables has become more and more important. [0003] The shock-absorbing device of the existing cable-stayed detection robot connects the mova...

Problems solved by technology

[0005] Since the force of the spring of the shock absorber is perpendicular to the surface of the cable, the clamping method of the robot is limited. Although the three-sided clamping method can clamp firmly, it needs to use six electric push rods to form a triangle, and the overall shape of the machine will be affected. It looks large and bulky, which affects daily transportation and practical use;

[0006] The motor and wheels are installed...
