Checking vehicle for measuring the height and offset of the contact wire or wires of electric aerial (overhead) contact lines on railway tracks

摘要

The invention relates to a checking vehicle for measuring the height and offset of the contact wire or wires of electric aerial contact lines on railways, comprising in particular a measuring rod 213 parallel to a reference plane passing through the two rails 101 of the railway track, and mounted so that it can move (arrow V1) in order to come to bear against the contact wire or wires so that its excursion makes it possible to measure the height of the contact wires of the conducting cable, this measuring rod 213 being provided, along its length, with a graduated scale making it possible to measure the offset of the abovementioned contact wire or wires. Such a vehicle is noteworthy in that it is made up of a railway platform I associated with a measuring instrument II which, mounted suspended on the bed 10 of the said platform I, movable independently of the latter, is equipped at its top with the abovementioned measuring rod 213 and at its bottom with an axial assembly 203a for running on the said rails 101. Application: measuring the height and offset of the contact wire or wires of electric aerial contact lines on railway tracks. IMAGE
