Problems solved by technology

[0005] The height difference (guide height) and lateral distance (pull-out value) between the contact rail and the basic rail, as well as the degree of wear (wear) all directly affect the reliability and stability of the traction power source of the subway train. An important parameter, mainly relying on manual and traditional measurement or simple electronic measuring equipment for point-by-point static detection, so the number of samples is relatively small, and the efficiency is low, the detection items are limited, and the status of the contact rail cannot be completely and accurately reflected. In order to ensure continuous and stable current and to ensure that the contact rail is in a normal working state, a more comprehensive inspection of the contact rail plays an important role in improving the quality of the current. This requires us to be able to timely and reliably grasp the work of the contact rail status, make a scientific evaluation and management of it, and make an accurate judgment basis for the subsequent planned maintenance

Abstract

The invention discloses a mobile contact rail detection device, which comprises a trolley arranged on a rail, wherein one side of the trolley is telescopically provided with a measurement unit capableof extending into the lower part of a contact rail, and the trolley is provided with a host in communication connection with the measurement unit; the measurement unit is configured to comprise a first industrial camera, a second industrial camera and a laser, the first industrial camera and the second industrial camera are matched with the contact rail to acquire 3D point cloud and / or picture information; and the laser is arranged on one side of the second industrial camera. According to the mobile contact rail detection device provided by the invention, a measurement probe can be erected below the contact rail through the arranged telescopic measurement unit on the premise of ensuring a reliable measurement reference so as to carry out continuous scanning measurement on the contact rail. The measurement probe is stored in the main body after being used, so that the measurement probe is protected, and the volume of equipment during transportation is reduced.

Description

technical field [0001] The invention relates to an instrument device for detection. More specifically, the present invention relates to a mobile contact rail detection device used in the detection of subway contact rail and its application method. Background technique [0002] With the rapid increase of urban subway mileage, the task of ensuring the safe, stable and reliable operation of trains is becoming heavier and heavier, and the workload is also increasing. At present, the electricity during the operation of the subway train is mainly obtained through the following two contact methods: [0003] The first is to obtain it from the catenary through the pantograph on the roof. The acquisition method is similar to the current high-speed rail traction power supply system. It is common in many patrol inspection instruments and high-speed rail equipment; [0004] The second way is to supply power through the contact rail. This method is currently a unique power supply method...
