Description

Technical Field

[0001] The utility model belongs to the technical field of rigid contact networks, and in particular relates to a rigid contact network contact line wear detection device. Background Art

[0002] The rigid contact network is a special form of contact network, which is mainly used in urban rail transit and electrified railway systems to provide electric locomotives with electricity. Compared with the traditional flexible contact network, it has the characteristics of compact structure, small headroom, and easy maintenance. The rigid contact network is mainly composed of overhead rigid busbars, contact wires, support and positioning devices, insulating components and overhead ground wires. These components together constitute a special form of transmission line for supplying power to electric locomotives. The suspension type of the rigid contact network is a type of contact network. It has a relatively simple structure, fewer parts, lower requirements for tensile strength, small installation space, low civil engineering costs, strong breaking resistance, small maintenance workload, and low maintenance costs.

[0003] The rail transit vehicle is driven by contacting the rigid contact network. However, the long-term friction between the top bow of the rail transit vehicle and the rigid contact network will cause wear of the rigid contact network. Therefore, the rigid contact network needs to be regularly inspected for wear.

[0004] However, installing the wear detection device on the outer wall of the rigid contact network can only detect wear in one direction of the rigid contact network. When the rigid contact network needs to be detected for wear in different directions, the wear detection device needs to be manually rotated, and manual rotation can easily cause errors in the measurement of the wear detection device.
