Embodiment Construction

[0030] For the sake of reference and clarity, the technical terms, abbreviations or abbreviations used below are recorded as follows:

[0031] 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.

[0032] 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 rail track measuring mark point positioning method. A rail track measuring mark point positioning device comprises a track inspection trolley, a linear laser, a controller and a power supply, wherein the track inspection trolley runs on a steel rail; the linear laser is arranged on the track inspection trolley and is perpendicular to the edge of a side part of a running direction, and a laser line emitted by the linear laser is perpendicular to the edge of the side part of a track inspection trolley body; the controller is arranged on the track inspection trolley and is used for controlling the linear laser to be switched on or off; and the power supply is arranged on the track inspection trolley and is used for supplying power to the linear laser. The track inspection trolley runs on the steel rail, and when the laser line emitted by the linear laser passes through a CPIII pile point or fixed point arranged beside the steel rail, the position, projected on the surface of the steel rail, of the laser line is a mark point position for the track inspection trolley to stop. The rail track measuring mark point positioning method described by the invention can solve the technical problems that the existing rail track measuring mark point positioning method is high in cost, low in efficiency, low in accuracy and low in degree of automation.

Description

technical field [0001] The invention relates to the technical field of railway track measurement, in particular to an intelligent positioning method 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 marked point to...
