Antiskid wheels for track detecting trolley

Abstract

The invention provides antiskid wheels for a track detecting trolley. The antiskid wheels are characterized in that synchronous belt wheels which are supported through shafts are respectively arranged at two ends of the bottom part of two shaft frame plates which are corresponding to each other in positions; the two synchronous belt wheels are equipped with closed-loop tooth-shaped synchronous belts which engage the two synchronous belt wheels; the outer rubber surfaces of the closed-loop tooth-shaped synchronous belts are jointed with the track surface; a top plate for supporting a trolley body is arranged on the top parts of the two shaft frame plates. According to the antiskid wheels, the jointing area of the outer rubber surfaces of the closed-loop tooth-shaped synchronous belts and the track surface is far more than that of steel wheels and the track surface in the prior art; the frictional resistance between the wheels and the track is relatively large due to the characteristic that the outer surfaces of the closed-loop tooth-shaped synchronous belts are prepared from rubber, and therefore, the slipping of the steel wheels is completely avoided. The antiskid wheels have outstanding advantages of being simple in structure, ingenious in concept and remarkable in 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
