Abstract

The invention discloses a device and method for measuring the inclination angle of a track, which belongs to a technique for measuring the irregularity of the track by using laser. According to the device and method for measuring the inclination angle of the track, in the train running direction, a first supporting component and a second supporting component are placed perpendicular to a train compartment floor; the upper surface of the first supporting component is always kept horizontal; the upper surface of the second supporting component is inclined with the inclination of the track; a laser is placed on the upper surface of the first supporting component to transmit a first light beam which is always horizontal; a first reflecting mirror is placed on the upper surface of the second supporting component and inclined with the inclination of the track; the first reflecting mirror is used for reflecting the first light beam to form a second light beam; a deflection detecting component receives the second light beam, detects the light path variation amount of the second light beam and outputs a detection signal; and a data analysis module calculates the inclination angle of the track according to the detection signal. The device and method for measuring the inclination angle of the track is advantaged in that the track is detected more conveniently and the detection effect is sensitive.

Description

technical field [0001] The invention belongs to the technical field of track irregularity detection, and relates to a device and a method for measuring the inclination angle or local deformation of a track by using a laser. Background technique [0002] Rail transit has a large volume, fast and convenient transportation, low energy consumption and high efficiency, which has brought great convenience to people's work and life. Due to the unevenness of the railway track, the impact load of the wheel and rail is caused, which leads to a large force between the wheel and the rail, which can cause damage to the rails, wheels and other components in light, and cause serious accidents in serious cases, threatening people's lives and property. Therefore, track irregularity detection technology has become a key issue in high-speed railway construction technology. [0003] At present, the detection methods used to measure the track irregularity are as follows: two-point difference me...
