Embodiment Construction

[0032] For the sake of reference and clarity, the technical terms, abbreviations or abbreviations used below are recorded as follows:

[0033] CPⅢ: The abbreviation of foundation pile control network, a three-dimensional control network proposed by the former Ministry of Railways of the People's Republic of China to be laid along the railway line. Starting from the second-class level network laid along the line, it is usually measured after the completion of the offline engineering construction, which is the benchmark for track laying and operation and maintenance.

[0034] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Apparently, the described embodiments are only some of the embodiments of the present invention,...

Abstract

The invention discloses a railway track measurement marking point positioning device and system. The device comprises a track detection car, a line laser device, a controller and a power supply, wherein the track detection car moves on steel rails; the line laser device is arranged at the edge of the side part vertical to a movement direction of the track detection car; laser line emitted by the line laser device is vertical to the edge of the side part of the track detection car; the controller is arranged on the track detection car and is used for carrying out off-on control on the line laser device; the power supply is arranged on the track detection car and supplies power to the line laser device. The track detection car moves on the steel rails; when the laser line emitted by the line laser device passes through a CPIII pipe point or a fixed point arranged beside the steel rails, the laser line is projected to a position on the surfaces of the steel rails and the position is a marking point position where the track detection car needs to be parked. With the adoption of the railway track measurement marking point positioning device and system disclosed by the invention, the technical problems of an existing railway track measurement marking point positioning manner that the cost is high, the efficiency is low, the precision is low and the automation degree is low can be solved.

Description

technical field [0001] The invention relates to the technical field of railway track measurement, in particular to an intelligent positioning device and system for track measurement mark points applied to a railway track inspection instrument. Background technique [0002] In order to meet the needs of precise tamping and maintenance of railways, it is usually necessary to build a network and accurately measure the relevant lines to provide the benchmark database and line deviation files required for precise line measurement and maintenance. The data provided by the measurement include fixed points or CPⅢ Stake datum data. Whether it is in the existing line, or in the network construction measurement or precise line measurement of the existing CPⅢ pile line such as the passenger dedicated line, it is necessary to mark the set fixed point or the nearest point corresponding to the existing CPⅢ pile point on the rail. , so that the track inspection instrument stops at the mark...
