Overhead n-shaped rigidly suspended contact wire abrasion continuous measurement apparatus

Abstract

The invention provides an overhead n-shaped rigidly suspended contact wire abrasion continuous measurement apparatus. The overhead n-shaped rigidly suspended contact wire abrasion continuous measurement apparatus includes a host computer and a lower computer, wherein the host computer includes a detection vehicle body, a running mechanism on the detection vehicle body, a 2D laser abrasion measurement apparatus, a abrasion morphology image acquisition apparatus, an equidistant synchronous trigger apparatus and a data processing unit, wherein the running mechanism takes a groove of a busbar as a continuous moving track, and is used for going forward, going backward or stopping under control of the host computer; the 2D laser abrasion measurement apparatus is used for measuring the two dimensional space contour data of a contact wire; the abrasion morphology image acquisition apparatus is used for acquiring the image information of the contact wire; the data processing unit is used for calculating abrasion according to the contact wire contour data, synchronously integrating the abrasion and image information and then sending the abrasion and image information to the host computer; the equidistant synchronous trigger apparatus is used for providing an equidistant pulse trigger signal; and the host computer includes a remote control unit and a display which are respectively used for sending a running control command to the lower computer and displaying the abrasion and image information sent from the lower computer.

Description

technical field [0001] The invention relates to the technical field of electrical measurement, in particular to an overhead "П" type rigidly suspended contact wire wear continuous measurement device. Background technique [0002] In 1983, the "Π" overhead rigid suspension system, one of the main types of overhead rigid suspension, was adopted in the RATPA line in Paris, France. The "Π" type rigid suspension catenary system has been widely praised in my country's urban rail industry for its simple structure, convenient installation and maintenance, safety and reliability, and high localization rate. From 1997 to April 2000, under the general contract of China Railway Electrification Bureau Group Co., Ltd. Shanghai Metro Engineering Company, a 135-meter "Π" aluminum alloy was carried out at Hangkou Station of Guangzhou Metro Line 1 - Huadiwan Station After the busbar rigid suspension catenary test section, this installation form was officially introduced into my country, and i...

Problems solved by technology

There are many uncertain factors in this measurement method: first, the positioning and fitting with the bus bar is only manual, and the stability is poor; second, conductive paste, dust, dirt, and ablation pits are easy to accumulate on the bonding surface, which affects the measurement accuracy; Finally, there is no locking mechanism in the positioning method, which is prone to skewed measurement and affects the measurement accuracy

In addition to the above deficiencies, the biggest disadvantage of the existing hand-held Moor measuring device is that the measurement can only achieve single-point measurement, and cannot achieve continuous measurement, and maintenance personnel cannot intuitively grasp the wear status of the contact wire
