Robot main body mechanism for climb cable

Abstract

The invention relates to a robot body apparatus of climbing rope, belonging to the robot technical field. The robot body apparatus comprises the following: two track apparatuses (1,2) of upper and lower which are symmetry distributed along a cable (16) direction, wherein, the track apparatus (1,2) comprises a floor (14), a pre track wheel and a post track wheel (7,12) which are arranged on the floor (14) through a bearing support, a motor (17,13) for driving the pre and post track wheels (7, 12) and a track (8); the two track apparatuses (1,2) of upper and lower is clamped on the cable through the floor (14) by a clamping device (3); the anterior and the posterior of the floor (14) are respectively provided with guide mechanisms. The robot body apparatus of climbing rope has the advantages of simple structure, convenient assembly and disassembly, stationary clamping and shifting on the cable, high functional reliability.

Description

technical field [0001] A robot body mechanism used for climbing cables is mainly used for robots working on long-span cable-stayed bridges and electric wires, and belongs to the technical field of robots. technical background [0002] The cable-stayed bridge mechanism is now widely used in bridge construction because of its many advantages. It is expected that dozens of cable-stayed bridges will be built on the Yangtze River in the next few decades. The cables, which are key parts of cable-stayed bridges, are always exposed to the air and corroded by acid rain. The protective structure on the surface is easy to age and fall off, causing rust on the surface of the cables. Furthermore, because the length of the cable is relatively long, it is easy to swing and vibrate under the action of the wind, causing internal stress and microcracks to occur inside the cable. This makes the daily maintenance of the cables, such as painting and stress testing of the cables, essential. ...

Problems solved by technology

[0003] For the wire maintenance of power equipment, especially in severe weather conditions such as blizzards, the wires are easy to freeze, which greatly threatens the safety of the power grid and the life of the wires. Therefore, an automated robot mechanism is needed for De-icing work on wires

[0004] Utility Model Patent No. 99252056.8 discloses a climbing mechanism for an electric-driven cable maintenance robot. It adopts a cylindrical frame structure, and three mobile trolleys are evenly distributed along the circumferential direction of the cable in the frame. The climbing mechanism is clamped on the cable through wheels, and the wheels and the cable The contact area is relatively small, the pressure is relatively large, and the robot climbing mechanism with a wheel structure does not have a good climbing ability on frozen wires

The movement mode of this pneumatic peristaltic cable robot climbing device is peristaltic forward, and the cylinder needs the air source on the ground to supply it, which makes it not very convenient to use
