In the running process of trains, the number of the trains running in the same direction and running in the opposite directions is large, and due to crustal movement, a railroad bed can transversely deviate to a certain degree. Therefore, when the driving safety and the personal safety of passengers need to be guaranteed, measurement of a bidirectional rail limit is necessary. According to a bidirectional rail clearance measuring method, a laser measuring instrument (1) and a trolley (2) on a rail (3) are mainly included. The laser measuring instrument (1) is placed in the center of the top ofthe trolley (2), so that the trolley (2) can move on the rail (3). The method mainly comprises the steps that the laser measuring instrument (1) is operated to emit laser to a designated point on theinner side of a track horizontally downwards, then a laser signal is received, the distance between a laser emitting point (the center of the track) and the inner side point of the track is obtained,and the distance between the centers of the two tracks is calculated through trigonometric function calculation and data processing. The data obtained by the method is more accurate, the efficiency is higher, fewer workers are needed, the safety of the workers is ensured, and meanwhile, the cost is reduced.

    列车行车途中,同向行驶反向行驶会相遇的列车数量比较多,而且由于地壳运动,铁路路基就会出现一定程度上的横向偏移。为此,在需要保证行车的安全,保证旅客的人身安全,对双向铁轨限界的测量就必不可少。双向铁轨限界测量方法主要由激光测量仪(1)和轨道(3)上的小车(2)构成。把激光测量仪(1)放置在小车(2)的车顶部中心,使小车(2)能够在轨道(3)上移动。本方法主要是通过操纵激光测量仪(1)水平向下对轨道内侧指定点发射激光,然后接受激光信号,获得激光发射点(轨道中心处)到轨道内侧点的距离,通过三角函数的计算以及对数据的处理,计算出两轨道中心距的距离。这种方法所得到的数据更加准确,并且效率更高,减少了劳动人员的使用,保障了人员的安全性,同时,减少了成本。
