Description
Technical Field
The invention belongs to the technical field of railway track structure detection, and particularly relates to a track slab gap detection vehicle capable of avoiding obstacles.
Background
One of the main defect types of the slab ballastless track is interlayer gap of a track structure. The generation of the gap can influence the smoothness and the dynamic response of the track on the one hand, and in addition, the contact state and the longitudinal temperature force transmission characteristic between the track plate and the supporting layer (mortar layer) are also inevitably changed, and the stability of the track structure is influenced.
Because interlayer separation seams generally exist in the lines, and the separation seams have different heights. Under the existing conditions, railway maintenance workers must carry out on-site measurement, and can formulate a maintenance scheme after preliminarily mastering the distribution condition of the gap between the track structural layers on the line, thereby realizing effective management.
Because the high-speed railway is operated in a totally-closed manner in daytime, the check of the interlayer separation seams of the track structure mainly depends on manual unfolding of a maintenance skylight at night, and a main tool for measuring the interlayer separation seams of the track structure is a feeler gauge. This way of checking has the following drawbacks: (1) visual conditions are poor at night, and the rail structure gap inspection is difficult to refine; (2) the manual detection is strong in subjectivity, and the detection efficiency is low due to the fact that the circuit detection is large in robustness; (3) in long-distance operation, the reliability of manually recording the line mileage corresponding to the gap and the track slab number is not high, and the omission and the mistake recording are inevitable. Therefore, automatic detection equipment for the rail plate gap needs to be developed.
At present, some automatic detection researches about the track slab separation seam are in a test stage, and the automatic detection equipment can not detect the internal state of the separation seam by detecting from the oblique upper side of the track slab separation seam, has the defects of inaccurate detection result and incomplete detection data, and leads a maintenance scheme made by a worker for the track slab separation seam to not conform to the reality.
In addition, lateral stop blocks are arranged on two sides of a part of slab ballastless track, and the purpose is to play a role in limiting and buffering for the lateral displacement of the track slab; the lateral stop blocks are large in size and short in interval, when the track slab gap automatic detection equipment moves, the lateral stop blocks become obstacles, and other uncertain obstacles may exist to influence the safety of the track slab gap automatic detection equipment.
