Abstract

The invention provides a track lofting gauge. The track lofting rule comprises a main beam, a fast wheel and a measuring wheel, wherein the main beam has the upper part provided with a track gauge sensor and an inclination sensor and the lower part provided with a left rail beam and a right rail beam; a rail-top prism and the fast wheel are arranged on the upper side and the lower side of the left rail beam respectively; a center prism is arranged on the main beam, and the center point of the center prism is arranged on the connection line between lower ends of the left rail beam and the right rail beam; the measuring wheel is arranged on one end of a support bar of the measuring wheel, and the track gauge sensor is arranged on the other end of the support bar of the measuring wheel; a pull rod is connected with the support bar of the measuring wheel; the main beam is also provided with an electric control box provided inside with a single-board computer; the track gauge sensor and the inclination sensor are connected with the electric control box by cables respectively. The track lofting gauge can automatically measure coordinates of the rail-top prism and the center prism by an electric total station, thereby realizing the absolute measurement of the three dimensional coordinates of the track center.

Description

technical field [0001] The invention relates to an accurate measurement and positioning device for setting out a track to a theoretical position during railway construction, in particular to a track setting out ruler and the measurement and positioning device. Background technique [0002] When building a railway, it is necessary to place the rail on the design value given by the design institute. The traditional method is to use a total station to stake out the plane coordinates of the center line of the line, and use a level to stake out the elevation of the line center line, so as to obtain the three-dimensional coordinates of the line center line, and then Utilizing the relative position relationship between the center line and the two rails, the relative position of the two rails is manually determined by using a track measuring ruler and a total station. [0003] The railway track detection ruler disclosed in ZL200520023701.3, the electronic track detection ruler discl...
