Odometer device for laying rails work-vehicle

Abstract

The utility model relates to a trip meter device for a track-laying operation vehicle, which comprises a detection part and a fixed part; the detection part includes a trip wheel in contact with the surface of a steel rail and an encoder for feedback signals; The structure of the components is as follows: the guide sleeve is vertically installed under the installation beam fixed under the body of the work vehicle, the upper end of the guide column is sleeved in the guide sleeve, the lower end is equipped with a detection device, the lifting cylinder is installed in parallel with the guide column, and the upper end of the lifting cylinder is fixed. Outside the guide sleeve, the free end and the guide post are detachably connected, the two are fixedly connected in the hanging state, and the two are disengaged in the working state. The guide column is controlled by the lifting cylinder to move up and down, and can be retracted and released to change the working state. When the invention works, the trip wheel is depressed by its own weight on the rail surface, and the guide post and the guide sleeve form a kinematic pair, which can move flexibly vertically along the guide post, effectively eliminate the impact of the frame and the vehicle-mounted gantry crane on the trip accuracy, and ensure the accuracy of the trip. Accurate travel, prolong the service life of the travel meter.

Description

technical field

[0001] The invention relates to a trip meter, in particular to a trip meter for a track-laying operation vehicle. Background technique

[0002] The meter device is a device installed on the track-laying vehicle to accurately measure the traveling distance of the track-laying unit and transmit the information to the control system. The signal provided by the device has an important influence on the sleeper laying speed and sleeper laying error of the track laying vehicle, and the sleeper laying speed and sleeper laying error are weight indicators to measure the technical level of the track laying work vehicle. Therefore, the taxi meter is used as a device for collecting raw data. Whether it can collect signals and ensure the accuracy of the signals directly affects the performance of the vehicle. In the prior art, such as TCM60, PC-NTC and other track-laying units, the metering device is generally located behind the two-position bogie of the work vehicle, and...
