Cable detection robot

Abstract

The invention provides a cable detection robot which is composed of two carts, namely, a driving cart and a driven cart, distributed evenly along the circumferential direction of the cable and connected by a connecting piece. The driving cart is provided with a climbing device, the driven cart with a clamping device and the connecting piece with a deviation prevention device. The climbing device comprises a lithium cell fixed to the body of the cart and a direct current motor fixed to the side of the driving wheel of the body of the cart and the clamping device comprises a pole bracket, one end of which is movably connected with the body of the cart in a swinging manner along the radial direction of the cart, an extension spring and a pulley connected with the pole bracket. The climbing device of the cable detection robot implementing the invention has simple structure and convenient maintenance; power supply by the lithium cell is more suitable for aloft work environment, the application is safer and more reliable and the operation is stable.

Description

technical field [0001] The invention relates to an industrial robot, in particular to a robot for cable detection. Background technique [0002] Cable-stayed bridges and suspension bridges are the basic forms of modern long-span bridges. After the completion of cable-stayed bridges and suspension bridges, the cables, one of the main stress-bearing components, will be exposed to the air for a long time, and the polyethylene (PE) protective layer on the surface of the cables will show different degrees of hardening and aging. Corroded by moisture and other acidic substances in the air, and even broken wires in severe cases, endangering the safety of the bridge. [0003] At present, the maintenance measures for bridge cable inspection are not perfect, and the inspection and maintenance of cables are mainly done manually. For example, a hoist is used to drag the trolley, equipped with detection sensors to detect broken wires, wear, and rust spots of the cable, and to re-spray ...

AI Technical Summary

Problems solved by technology

However, the climbing device of the cable inspection and maintenance robot has a complex structure; the whole machine is powered by cable, and the length of the connecting cable must be greater than the length of the bridge cable that the robot climbs, so it is easily affected by wind when working at heights; The relevant descending device, when an accident occurs during the operation, uses a steel wire rope connected to the robot to drag and recover the robot from a height of tens or even hundreds of meters, and the operation is extremely dangerous

The applicant applied for a patent with the application number 200620016413.X. This technical solution can better complete the cable detection work, but the mechanism is complex, the manufacturing requirements are high, the drop is easily affected by the damage of the cable surface, and it will deviate from the detection in certain places. object, resulting in inaccurate detection results
