Inertia assembly measuring mechanism for rail measurement

Abstract

The invention discloses an inertia assembly measuring mechanism for rail measurement. The inertia assembly measuring mechanism comprises a walking device, an inertia measuring assembly, a battery, aninertial navigation connector, an expansion module interface and a spike interface. The inertia assembly measuring mechanism has the beneficial effects that 1) the inertia assembly measuring mechanismhas high-precision detection functions of mileage, rail gauge, superelevation, levelness, height and rail direction; (2) the collected data can be processed in real time through a processing computercarried on the equipment, then a detection result is directly outputted as a report and an oscillogram on line, and a rail quality index (TQI) report is outputted so that an over-limit early warningfunction is realized; 3) the measuring system has a fastener spike identification function and can judge whether the fastener installation distance meets the standard or not and can also judge whetherthe fastener is lost or not and can position the detected disease with high precision; and equipment and sensors of the rail geometrical parameter detection platform can realize automatic and continuous detection of the rail geometrical parameters of rail transit.

Description

technical field [0001] The invention relates to the field of orbit measurement, in particular to an inertial component measurement mechanism for orbit measurement. Background technique [0002] With the rapid development of my country's economy and the rapid advancement of rail transit construction, the pressure on the rail transit system is increasing, and the traffic density is also increasing. The track is the basic carrier in the system. Therefore, high-precision detection of various geometric parameters of the track is an important basic work to ensure safe operation. The geometric parameters of the track are important technical indicators to measure the quality of rail transit lines, to ensure the safe running of trains, to ensure that passengers on board feel stable and comfortable, and to guide track maintenance and repair. [0003] There are many geometric parameters of the track state, among which the more important geometric parameters mainly include: mileage, ga...

Problems solved by technology

The main disadvantages of this method are: low efficiency, the measurement data is discrete, not suitable for the measurement of internal geometric parameters of the track, the types of measured data are limited, the detection of rail transit diseases is not comprehensive enough, and there is a lack of real-time online continuous processing of disease information data ability

There is also a way of testing with portable measuring instruments, but it also has the defects of low efficiency and poor accuracy
