Maintenance and detection apparatus and maintenance and detection method of contact wire for high-speed train

Abstract

The invention relates to the technical field of high-speed railways, and discloses a maintenance and detection apparatus and maintenance and detection method for a contact wire for a high-speed train. The maintenance and detection apparatus comprises a train compartment, an empty slot, a fixed plate and an air bag, so that the apparatus can be synchronous with the layout trend of the contact wire; a high-pressure water spraying mechanism is fixedly mounted at the top of the fixed plate and is used for spraying high-pressure water to remove ice on the contact wire; an air injection mechanism is fixedly arranged at the top of the fixed plate and is used for removing snow on the contact wire and drying water on the contact wire; a temperature sensor is fixedly arranged above one side of an upper plate and is used for detecting the heat of the contact wire which has performed electric conduction; and a marking mechanism is fixedly arranged on the side, away from the temperature sensor, of the upper portion of the upper plate and used for marking an auxiliary carrier cable above a pile head with the abnormal temperature. Therefore, the apparatus can remove the snow and ice on the contact wire, record the abnormal conductive temperature, detect whether the pile head is loosened or not and mark the pile head.

Description

technical field [0001] The invention relates to the technical field of high-speed railways, in particular to maintenance and testing equipment and a maintenance and testing method for contact wires used in high-speed trains. Background technique [0002] High-speed railway catenary is a transmission line erected along the railway line to supply power to electric locomotives. The current that high-speed trains rely on is transmitted through the catenary on the upper end of the locomotive. During the operation of the high-speed rail, the pantograph is mainly used to take power after contacting the catenary. When the catenary power is transmitted, the catenary cable and the catenary wire are connected by pile heads, and the pile heads are directly engaged on both sides of the catenary wire. On the groove, and the contact pressure between the catenary and the pantograph is about 100N. When high-speed trains run on high-speed railways, the following problems will occur: [0003...

AI Technical Summary

Problems solved by technology

[0009] Aiming at the deficiencies of the prior art, the present invention provides a maintenance and detection device for contact wires for high-speed trains, which has the advantages of snow removal and ice removal, and is convenient for detection and positioning, and solves the problem that the train cannot take power due to ice and snow accumulation on catenary wires and pile head loose problem
