In particular, there are a large number of 70-meter sections with poor track direction on the line. The traditional method of threading with theodolite is inefficient due to the high density of trains, the troublesome installation and operation of the instrument, and the difficulty in operating outside the skylight point. It is not easy for the team to master it. The operation within the skylight point takes up precious maintenance skylight time. At the same time, the utilization rate of large-scale laser track shifting is not high, and the track shifting amount needs to be provided manually in advance. Therefore, the traditional maintenance method that relies mainly on personal experience and the use of measuring instruments that do not conform to the actual situation on site can no longer meet the requirements of equipment quality maintenance. Therefore, there is an urgent need for a miniaturized and simple device that can quickly and accurately measure the center line of the line and provide accurate track shifting data for daily track shifting operations and large-scale road maintenance machinery operations.
