Problems solved by technology

[0002] Existing track detectors can only measure the internal geometry and external geometry of ordinary T-shaped rails, but this kind of track detector cannot be adapted to the measurement and detection of F-shaped rails that are unique to medium and low-speed magnetic levitation
The construction and testing of my country's maglev railway lines are still in their infancy. The special cross-sectional shape of the medium and low-speed maglev F-shaped rail is different from that of ordinary "I"-shaped rails. Existing rail inspection instruments cannot cope with the measurement of various unique internal geometric parameters of F-shaped rails

Embodiment Construction

[0023] The present invention will be further described in detail below in conjunction with specific embodiments and accompanying drawings.

[0024] Such as figure 1 and figure 2 As shown, the track detector for medium and low speed maglev F-rails of the present invention includes a walkable frame and a data measurement system installed on the walkable frame. The data measurement system includes a gauge measuring mechanism and an F-rail Measuring mechanism for geometric parameters. The walkable frame includes a left plate frame 1 and a right plate frame 11, the left plate frame 1 and the right plate frame 11 are connected by a plate frame intermediate shaft 30, and the plate frame intermediate shaft 30 is provided with a convenient adjustment The intermediate shaft quick connection knob 17 and the intermediate shaft positioning knob 16 can make two plate racks be placed on the track according to the actual needs between the tracks. The bottoms of the left plate frame 1 and ...

Abstract

The invention discloses a rail detecting instrument for a low and medium speed magnetic suspension F-type rail, which comprises a travelable machine frame and a data measuring system, wherein the data measuring system is arranged on the travelable machine frame. The data measuring system comprises a rail distance measuring mechanism and F-type rail geometric parameter measuring mechanisms. The travelable machine frame comprises a left plate type machine frame and a right plate type machine frame which are connected by a middle shaft of the plate type machine frame. The rail distance measuringmechanism is arranged between the left plate type machine frame and the right plate type machine frame which are respectively provided with one F-type rail geometric parameter measuring mechanism. The invention has the advantages of simple and compact structure, small size, light weight, high measuring precision, stable running, quick disassembly and assembly, and convenient carrying, and integrates various geometric shape measurements of the F-type rails.

Description

technical field [0001] The invention mainly relates to the field of magnetic levitation vehicles, in particular to a magnetic levitation track measuring device. Background technique [0002] Existing track inspection instruments can only measure the internal geometry and external geometry of ordinary T-shaped rails, but this track inspection instrument cannot be adapted to the measurement and detection of F-shaped rails that are unique to medium and low-speed maglevs. The construction and testing of my country's maglev railway lines are still in their infancy. The special cross-sectional shape of the medium and low-speed maglev F-shaped rail is different from that of ordinary "I"-shaped rails. Existing rail inspection instruments cannot cope with the measurement of various unique internal geometric parameters of F-shaped rails. Contents of the invention [0003] The technical problem to be solved by the present invention is: aiming at the technical problems existing in the...
