Problems solved by technology

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. Disadvantages: such as relatively bulky, large energy consumption and other shortcomings

Abstract

The invention discloses a rotating platform mechanism used for detecting a cable. The rotating platform mechanism comprises a connecting rib plate, a positioning part, a driving device and a measuring device, wherein the positioning part is fixedly connected with the connecting rib plate, the driving device and the measuring device are connected with the positioning part, the driving device is used for rotating the measuring device, and the measuring device is used for measuring the size of the cable. The rotating platform mechanism can rotate around the cable, so that the sizes of different positions of the cable are measured accurately, and the damage situations of protrusions or grooves of the surface of the cable are detected.

Description

technical field [0001] The invention belongs to the technical field of robot application, and in particular relates to a rotating platform mechanism for detecting cables. 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 serio...
