Adjustable deviation prevention device based on cable detection robot

Abstract

The invention discloses an adjustable deviation prevention device based on a cable detection robot. The adjustable deviation prevention device comprises a support shaft connected with a cable detection robot support leg, a fixing frame arranged on the support shaft, a deviation prevention support frame connected with the support shaft, a stepped shaft connected with the deviation prevention support frame, and a deviation prevention wheel arranged on the stepped shaft. The support shaft passes through the fixing frame; meanwhile, two horizontal extension plates are arranged on the bottom side of the fixing frame, one side is clamped on the cable detection robot support leg, and the other side is clamped on the deviation prevention support frame, so that one face of the fixing frame is attached to the support leg, and the other face of the fixing frame is attached to the deviation prevention support frame.

Description

technical field [0001] The invention is an adjustable anti-deviation device applied to a cable detection robot and belongs to the field of robots. Background technique [0002] With the rapid development of economy and transportation, the development of long-span bridges is getting faster and faster. As a new type of modern bridge, cable-stayed bridges have been widely used in the world. 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. Up to now, there have been several unfortunate engineering examples in which all cables of cable-stayed bridges have been replaced due to serious corrosion of cables w...

Problems solved by technology

[0003] So far, the inspection and maintenance methods for inclined cables are still relatively backward. In the early days, the hoist was used to move the equipment along the cable, and the test data was recorded or stored for analysis; The friction wheel is pressed to make the robot climb continuously or the air-driven cylinder is clamped to creep and climb. Using the accompanying spraying, magnetic detection and other devices, the coating and internal inspection of the in-service cables are realized. However, these two robots still have many shortcomings. Disadvantages: such as relatively bulky, large energy consumption and other disadvantages

[0004] The applicant has previously filed a patent application for a cable-stayed lock detection robot, but the previous robot did not have an anti-deviation device. As a result, the wheels of the cable detection robot were easily detached from the cables during crawling, resulting in failure of crawling or wear of the wheels. Derailment cannot complete the detection work
