Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of rail transit detection, and more specifically to an urban rail transit fault detection device. Background Art
[0002] Urban rail transit refers to the transportation system such as subways and light rails built in cities, which use steel rails or concrete tracks and use electric power to drive trains on fixed tracks. It is an efficient, fast and environmentally friendly public transportation method that can alleviate urban traffic congestion and provide convenient travel services.
[0003] During railway construction and maintenance, it is crucial to ensure the accuracy of track spacing, because incorrect track spacing may cause train derailment or poor operation. Track spacing is usually measured using special measuring tools. Inspectors place the measuring device on the top of the two tracks to measure the track spacing to determine whether the track spacing meets the standards. However, during existing manual inspections, it is necessary to bend down to place the measuring device at certain distances and then pick it up. This sampling measurement method has low reliability of the test results and causes great physical harm to the inspectors. Utility Model Content
