Laser measuring instrument for track lifting and lining for railway works

Abstract

The invention discloses a laser measuring instrument for track lifting and lining for railway works, which comprises a laser emitter device, a measuring device, a monitoring and correcting device and three walking trolleys. The laser emitter device, the measuring device and the monitoring and correcting device are arranged on one walking trolley respectively; the laser emitter device, the measuring device and the monitoring and correcting device are all provided with wireless communication devices and are communicated in a wireless mode; the laser emitter device comprises a track lifting laser, a track lining laser, a laser processor and a touch screen; and the measuring device and the monitoring and correcting device comprise an optical imaging system, a CCD sensor, a measuring processor, a touch screen, a horizontal sensor, and the like. The laser measuring instrument uses laser as a reference line, solves the problem of measuring the track lifting and track lining amount of long distance (more than 200 meters) in railway works department by measuring the position of the laser through the optical system and the CCD sensor, can carry out high-precision detection for railway line smoothness, provides reliable measuring basis for railway maintenance, and has high measuring precision.

Description

technical field [0001] The invention relates to a measuring instrument used by the railway engineering department for the track setting operation of rails, in particular, it is an instrument and equipment used for leveling railway rails, finding deviations and cooperating with large engineering machinery. Background technique [0002] The smoothness of railway rails will be affected after long-term operation. The straight track becomes a track composed of many wavy "curves". The curved track is no longer smooth, which will cause the train to shake and snake. The increase of power will accelerate the deformation of the track bed, which in turn will expand the unevenness, so that the train will have greater destructive power on the track, resulting in a vicious circle. Moreover, the smoothness of the track will also cause the contact surface of the train wheel and rail to be subjected to large impact dynamics, accelerate the wear and fatigue damage of the wheel and rail, short...
