Anti-skid wheels of track inspection trolley

Abstract

The present invention is an anti-skid wheel of a track detection trolley. The bottom ends of the corresponding two shaft frame plates are respectively equipped with synchronous pulleys supported by shafts. The rubber outer surface of the synchronous belt is joined with the surface of the track, and the top of the two axle frame plates is provided with a top plate supporting the main body of the trolley. The rubber outer surface of the closed-loop toothed synchronous belt of the wheel and the joint area of ​​the track surface are far greater than the joint area of ​​the steel wheel and the track surface in the prior art, and the characteristics of the rubber material on the outer surface of the closed-loop toothed synchronous belt cause this The friction resistance between the wheel and the track is relatively large, which completely overcomes the slipping phenomenon of the steel wheel. The invention has the outstanding advantages of simple structure, ingenious conception and superior performance.

Description

technical field [0001] The invention belongs to track detection equipment, in particular to an antiskid wheel of a track detection trolley. Background technique [0002] The track detection trolley is a convenient tool for detecting static track mileage and track irregularity parameters such as height, level, twist, and direction. [0003] The existing track detection trolley is composed of a trolley main body and a steel wheel supporting the trolley main body, and the wheels are rollingly engaged with the track. [0004] In order to keep the main body of the trolley stable when it moves with the wheels, one side of the main body of the trolley is provided with two front and rear wheels with a larger wheelbase, and only one wheel is provided on the other side. [0005] The above-mentioned wheels supporting the main body of the trolley are steel wheels, which have the following main defects: the frictional resistance between the wheel and the track is small, which causes the...

AI Technical Summary

Problems solved by technology

[0005] The above-mentioned wheels supporting the main body of the trolley are steel wheels, which have the following main defects: the frictional resistance between the wheel and the track is small, which causes the wheel to slip and affects the accuracy of the detection data of the main body of the trolley, especially when there are traces of rain and snow on the track surface. Serious; due to the strict requirements on the insulation between the main body of the trolley and the track, steel wheels will increase the complexity of the insulation structure of the trolley
