A magnetic levitation turnout rail wear measurement device and measurement method

Abstract

The invention discloses a measuring device and a measuring method for rail wear of a magnetic levitation switch. The measuring device comprises a general frame and three dial indicators arranged on the general frame. Probes of the three dial indicators are respectively in vertical contact with the upper surface and two side surfaces of a to-be-measured rail. A positioning stud is arranged on the general frame and is used for being in threaded connection with a positioning screw hole arranged on the ground at one side of the to-be-measured rail. According to the measuring device and the measuring method for rail wear of the magnetic levitation switch, a convenient, practical and efficient application tool can be provided for field measurement and maintenance personnel, so that the rail wearmonitoring work is facilitated, and the rail wear measuring work is simplified; a basis and a measurement criterion are provided for the field measurement and maintenance personnel to measure rail wear data; and the collision of the anti-lifting wheel and the rack of the switch is eliminated to provide a data reference and early warning for the field measurement and maintenance personnel, so as to grasp the rail wear condition in time and provide data indicators for timely taking measures to eliminate the hidden troubles.

Description

technical field [0001] The invention relates to the technical field of rail transit, in particular to a magnetic levitation turnout rail wear measurement device and a measurement method. Background technique [0002] During the frequent left and right movement of the maglev turnout, the track wear is serious, which makes the entire drive shaft system of the turnout move back and forth along the axial direction during the movement. figure 1 Shown is the camshaft shaft system and its relative positions, specifically including the following parts: motor 1, planetary gearbox 2, support shaft 3, drive shaft 4, cam wheel 5, rack 6, drive gear 7, anti-lift wheel 8. Support shaft seat 9, track 10 and foundation 11. when figure 1 When the cumulative amount of wear between the middle rail 10 and the profile wheel 5 reaches a certain level, when it exceeds the gap "X" between the anti-lift wheel 8 and the rack 6, it will cause the figure 1 The middle turnout rack 6 rubs against the ...

AI Technical Summary

Problems solved by technology

[0004] In terms of quantitative analysis and measurement of the degree of track wear, the track wear is more serious on the edges of the two sides of the track and the rolling area of ​​the upper surface of the contour wheel, and the wear on the upper surface of the track is more obvious in the form of corrugated concave and convex marks

[0005] However, directly using the dial indicator to measure will not be able to measure accurately due to the lack of measurement benchmarks
