Abstract

The invention relates to a mechanical structure of a novel high-speed rail track measuring instrument. The mechanical structure mainly comprises a transverse beam, a longitudinal beam, a high-low optical fiber gyroscope mechanism, a displacement sensor, a tilt angle sensor mechanism, a connecting block, a supporting frame, a display screen, a controller, a connecting wire, travelling wheels, handles, a battery case, an encoder and a track-direction optical fiber gyroscope mechanism. The whole mechanism comprises the transverse beam, the longitudinal beam, the controller and other measuring instruments, wherein the transverse beam and the longitudinal beam are fixedly connected, the transverse beam is arranged in the middle of the longitudinal beam, the battery case and a display and control system are installed on the transverse beam, and a plurality of sensors are fixedly connected to the transverse beam and the longitudinal beam, and used for collecting signals. The mechanical structure of the novel high-speed rail track measuring instrument has the advantages that the structure is simple, functions of collection, processing and display are integrated, absolute accuracy can be effectively guaranteed, operation is convenient, and working efficiency is high.

Description

technical field [0001] The invention relates to the field of control, in particular to a mechanical structure of a novel high-speed rail track measuring instrument. Background technique [0002] With the completion and opening of my country's first high-speed railway Beijing-Tianjin Intercity Passenger Dedicated Line, my country has officially entered the high-speed era. In recent years, my country has become the country with the longest operating mileage of high-speed railways and the largest scale under construction in the world. Today, with the rapid development of my country's high-speed railway, the traditional relative measurement mode can no longer meet the high-precision needs of my country's high-speed railway construction and operation and maintenance. For this reason, precision engineering measurement completely replaces traditional relative measurement. As a result, special track measuring instruments have also developed rapidly. During the track measurement, i...
