Embodiment Construction

[0018] Such as figure 1 , figure 2 As shown, a track correction measurement and control device, which includes a track parameter measurement trolley 2 installed together with a track shifting vehicle 1, an inclination sensor 4, and a pre-stored static curve recorded by the geodetic coordinate parameters of the rail under normal working conditions The vehicle-mounted computer 5 is equipped with a reflector 3 on the track parameter measuring trolley 2 of the track operation vehicle 1, and a total station 6 with an automatic tracking function installed on the center side of the track curve at the observation point position; A data link 7 for two-way flow of data is also established between the inclination sensor 4, the on-board computer 5 and the total station 6. superior.

[0019] In order to meet the needs of the operation section without geodetic coordinate survey datum point network, the device also includes a global positioning system GPS for the absolute geodetic coordin...

Abstract

The invention provides a device for measuring and controlling the track correction. The device comprises a track parameter measurement cart arranged along with a shift vehicle, an inclination sensor, a vehicle-mounted computer and a reflector total station, wherein a data link for bi-directional flow of data is established among the inclination sensor, the vehicle-mounted computer and the reflector total station; the method is as follows: a construction section is selected, and geodetical coordinates of the total station are measured; the total station locks a reflector, and a data connection channel is established, and the vehicle-mounted computer receives data from the total station and the inclination sensor and calculates the present curve parameters of the iron rail, which are compared with pre-stored static curve values of the iron rail which are recorded under the normal working conditions by taking geodetical coordinates as parameters, and control parameters controlling the track raising and lining clamp operation are generated and outputted, thereby forming a closed control process; such a circulation completes the construction of a section. The device has the advantages of eliminating errors of vibration and gravity-down due to the original use of steel chords, simplifying the measuring system, lowering the error probability of the complicated system and reducing the maintenance worklaod.

Description

technical field [0001] The invention relates to a measurement and control device and method for track correction. Background technique [0002] The track correction device is a special device of the tamping vehicle used for railway maintenance, which is used to move the railway rail to the desired position, so that the railway line can restore the designed curve shape. The static curve shape of the railway track must be corrected and maintained within a certain period of time. In the mechanical tamping vehicle used to maintain the railway line, the correction device is called a track-setting device. The track-setting device is generally composed of a track parameter measuring trolley and a Dial track clamps, in the most typical Plasser *Tauer company scheme, the measuring trolley includes a wheel axle running on the rails, an inclination sensor mounted on the wheel axle, a resistive displacement sensor and its corresponding steel strings , The rail shifting clamp includes a...
