Description

Technical Field

[0001] The invention relates to a mobile detection device and method for heavy-load railway gauge, and relates to the technical field of track structure gauge and height difference detection. Background Art

[0002] Rails are the main components of railway tracks. Their function is to guide the wheels of locomotives and vehicles forward, bear the huge pressure of the wheels, and transmit it to the sleepers. When the two rails have geometric deviations from the ideal position of the rails in terms of height and left and right directions, track unevenness will occur. Track unevenness is the fundamental cause of vibration of the wheel-rail system of high-speed railways and train snaking instability. It is also the cause of deteriorating the stability of the line structure and reducing its service performance. In severe cases, it will cause train derailment.

[0003] At present, the track gauge method is mostly used for testing the track structure. The operation method of measuring the track gauge includes preparing the track gauge, placing it on both sides of the rail, adjusting the position and aligning it with the inner edge, using a measuring tool to measure the distance, and recording the measurement results. The skylight in the railway refers to the time reserved for construction and maintenance operations when the train running line is not laid out in the train operation diagram or the train running is adjusted or reduced.

[0004] Traditional detection methods use manual operation, and the detection efficiency is low; using manual operation, it is inevitable that large errors will occur during the test, resulting in inaccurate detection results; when conducting track structure gauge testing, it can only be carried out in the skylight, and only the deformation data of a limited number of marking points can be read at the test position, which has limitations and lacks deformation data information of the track structure as a whole; and manual detection is time-consuming and labor-intensive, and the cost is high; the most important point is that the use of a track gauge for testing, although it is carried out in the railway skylight, still has a large safety hazard, which will have a certain impact on the personal safety of the tester. In order to solve the above problems, this patent provides a mobile detection device and method for heavy-duty railway gauge. Summary of the invention As introduced in the technical background, the problem of track unevenness seriously affects the safety of train operation.
