Continuous detection device and method for smoothness of rails

Abstract

The invention provides a continuous detection device and method for the smoothness of rails. The device comprises a horizontal laser transmitter, a vertical laser transmitter, a horizontal photoelectric positioning target, a vertical photoelectric positioning target, a horizontal movable photoelectric measurement target and a vertical movable photoelectric measurement target, wherein the horizontal movable photoelectric measurement target and the vertical movable photoelectric measurement target move arbitrarily in a rail detection section and are used for continuously measuring a horizontal deviation value and a vertical deviation value of each position of the rail detection section respectively. According to the continuous detection device for the smoothness of the rails, provided by theinvention, out-of-tolerance positioning and continuous detection work of a whole measurement process and tracking display detection work in a repairing process can be realized; furthermore, high-precision fixed-point detection work also can be realized.

Description

technical field [0001] The invention relates to the technical field of laser alignment measurement, in particular to a device and method for continuous detection of track smoothness. Background technique [0002] The track direction and height of the railway are two basic geometric parameters in the track smoothness inspection. Rail direction refers to the transverse unevenness of the inner gauge point of the rail along the extension direction of the track, whether it is straight on a straight line, and whether it is smooth on a curve. If the direction of the track is not smooth, it will cause the train to shake from side to side and snake, and thus increase the lateral impact force of the vehicle on the track. The height refers to the vertical height difference of the top surface of the track. When the front and rear heights of the track are uneven, bumps and impacts will occur when the train passes these tracks. The above-mentioned process can further aggravate the uneve...

Problems solved by technology

Due to the sinking and bending of filament strings, the poor precision of traditional steel ruler tools, and the uncertain factors of the natural environment and human observation, the problems of poor detection accuracy and low work efficiency are prominent, so it has been unable to adapt to the railway system after speeding up. The quality and efficiency of track maintenance requires

[0014] The above-mentioned commonly used equipment and methods are not suitable for promotion and use in the maintenance work area due to various reasons

At the same time, in the actual line maintenance operation, after confirming the planned maintenance site, it is necessary to specifically review the location of the accurate out-of-tolerance location. At present, the mileage marking of my country's railways uses the positioning method of adding track numbers to the kilometer mark and half-kilometer mark. For specific line maintenance and repair, the positioning accuracy is obviously low
