Contact wire online automatic detecting system device

Abstract

The invention discloses a contact wire online automatic detecting system device, which comprises a handheld type program logic electric control system, a wireless signal transmission system, a data storing, analyzing and printing system, a mini-type pneumatic measuring probe assembly and a handheld type microminiaturized pneumatic control system. The mini-type pneumatic measuring probe assembly comprises an instrument shell (1); a positioning mini-type cylinder (5) is arranged at the left side of the instrument shell (1); a translating jaw pair (13) is arranged below the positioning mini-typecylinder (5); a circular arc-shaped cavity (15) is arranged at a middle part of the instrument shell (1); a rotating body (2) is sleeved in the circular arc-shaped cavity (15); a rotating cylinder (6) is arranged at the right side of the instrument shell (1); the rotating body (2) is in rotary connection with a plunger (3) of the rotating cylinder (6); a rotating plate (8) is arranged on the rotating body (2); and a digital linear displacement sensor (11), an elastic shifting fork (10) and a mini-type probe cylinder (9) are respectively arranged on the rotating plate (8).

Description

technical field [0001] The present invention is a complete set of testing equipment integrating machine, electricity, gas, remote control and other cutting-edge technologies. It is applied to overhead high-voltage contact lines (27.5 kV AC) of my country's electrified high-speed railways and urban rail transit light rail and electric locomotive contact lines ( 1.5 kV DC) measurement. In the case of electrification, it can automatically detect the above-mentioned contact line on-line, and the abrasion caused by the relative friction with the pantograph of the locomotive when the locomotive is moving. Background technique [0002] Over the past half a century, foreign developed countries that mainly use electrified railways have invested a lot of human resources and material resources in the research and development of contact wire wear detection devices to ensure the operation and safety of high-speed railways. There are many types of products developed so far, but those with...

Problems solved by technology

Its shortcomings are: 1. The start of the work step and the conversion between the work steps must be completed by the manipulation of the ground crew seven meters away.

[0005] 2. The measuring rod imitating the movable jaw of a vernier caliper has weak clamping force, and the stability of measurement positioning and reference is not sufficient

[0006] Therefore, it is obvious that this type of measuring device cannot meet the requirements of contact wire detection for high-speed railways in my country.
