Track detector

Abstract

The invention discloses a track detector. The track detector comprises a machine frame, a gauge measuring device and a geometric parameter measuring device for an F-shaped track, wherein the machine frame consists of a horizontal beam, a vertical beam and a running device, and one end of the horizontal beam is connected with the vertical beam; the gauge measuring device comprises a first pressing device and a gauge measuring sensor, the first pressing device is connected with the other end of the horizontal beam through an elastic component, and the gauge measuring sensor is mounted at one end, connected with the elastic component, of the horizontal beam; the geometric parameter measuring device for the F-shaped track is arranged on the vertical beam and comprises second pressing devices, a data collecting sensor and one or more brackets allowing the data collecting sensor to be mounted, and during the operation, the first pressing device, the second pressing devices and the elastic component are matched to fasten the track detector on the F-shaped track. The main body of the machine frame consists of the horizontal beam and the vertical beam, so that the track detector is good in wholeness, not prone to vibrate, simple in structure and convenient to assemble, disassemble and carry.

Description

technical field [0001] The invention relates to the technical field of track geometric parameter detection, in particular to a track detector. Background technique [0002] Medium and low-speed maglev transportation is a low-noise and carbon-free transportation, and it is one of the important directions for future urban transportation development. Although it belongs to rail transit, it has different characteristics and advantages from traditional wheel-rail rail transit. Compared with ordinary wheel-rail subways and light rails, medium and low-speed maglev trains use suspension frames to run on the rails, without the risk of derailment, and have the advantages of safety and reliability, short construction period, low construction cost, low operation and management cost, and small turning radius. The running stability, safety and riding comfort of medium and low-speed maglev trains are largely related to the geometric state of the track. Since the track of medium and low-sp...

Problems solved by technology

The running stability, safety and riding comfort of medium and low-speed maglev trains are largely related to the geometric state of the track. Since the track of medium and low-speed maglev trains is an F-shaped track, it is different from the existing traditional wheel-rail tracks and high-speed maglev trains. The track geometry is different, and the track detector for the wheel-rail and high-speed maglev train track cannot be applied to the F-rail of the medium and low-speed maglev train

[0003] In the prior art, the track detector of the F-rail of the medium-low speed maglev train has a plate frame structure, although it can measure the geometric parameters of the F-rail of the medium-low speed maglev train, but in the implementation process, due to the vertical The rigidity is poor, the vibration generated is large, which affects the accuracy of the geometric parameters, and its structure is complex, the mass is large, and the installation and transportation are time-consuming and laborious
