Y-type rapid positioning device for measuring center position of railway track

Abstract

The invention relates to a Y-type rapid positioning device for measuring a center position of a railway track. At present, a track geometry state measuring instrument needs to be placed on a measurement position of a steel rail to carry out positioning in order to observe a three-dimensional space posture of the steel rail, and the collection efficiency is relatively low. The Y-type rapid positioning device disclosed by the invention comprises a Y-shaped baseplate with a hole in the middle; a locking nut is arranged in the hole in the middle of the Y-shaped baseplate; a prism bar is inserted into the locking nut; a half-cylinder is arranged at the bottom end of the prism bar and positioned on the surface of the steel rail; the top surface the prism bar is provided with a prism bar base of which the bottom surface is a concave spherical surface; the bottom end of the prism bar is inserted into a fixing groove formed in the top surface of the prism bar base; two symmetrical extruding ends are arranged on one side of the Y-type baseplate; the end part of each extruding end is provided with a downward steel rail clamp hook which is positioned on one side of the steel rail; the other end of each extruding end is connected with a fixing clamp which is positioned on the other side of the steel rail. The Y-type rapid positioning device disclosed by the invention can realize rapid positioning of the center position of the high speed railway track through a total station, so that the collecting efficiency is improved; the Y-type rapid positioning device is more portable, and simpler and more flexible to measure, and the measurement accuracy is greatly improved.

Description

Technical field [0001] The present invention is a railway measurement technology field, which involves a type Y -type fast positioning device used in the center of the center of the railway track. Background technique [0002] With the development of my country's high -speed railway construction, rail laid launching, completion acceptance, maintenance and maintenance work will be gradually carried out. In order to quickly understand the three -dimensional space attitude of the steel rails, the rail geometric state measurement device needs to be placed on the measurement location of the rails, and then the full through the full through the full through The stationary observation of the prism fixed on the rail geometric state measuring instrument, and then calculated the three -dimensional coordinates of the derailment center through the three -dimensional coordinate of the center of the prism center combined with the rail geometric state measuring instrument. , Thus knowing the de...
