On-line checkout equipment for contact pressure of motorcycle pantograph

Abstract

A locomotive pantograph contact pressure on-line inspection equipment is provided. One side of the track of the upright post at the outer side of track, the lower end of an elevating screw is fixed on the inner ring of the bearing of the supporting frame and passes through worktable supporting frame and the worktable and matched with an elevating nut on the installing frame; the worktable is fixed on the installing frame; a drawing press sensor is arranged on the work table close to the upright post, the steel rope connected with the sensor passes through the worktable and the installing frame and is connected with the one end of the horizontal insulator nearby; the other end of the horizontal insulator is connected with the horizontal insulator far, the connection part is hinged with the lower end of a vertical insulator and the vertical insulator passes through the worktable upward and fixed on the worktable; the other end of the horizontal insulator far is connected with a connect net clip downward; the drawing pressure sensor is electrically connected with the data processing and controlling equipment. The equipment can conduct dynamic detection on-line. The use is safe and convenient, the cost is low, the detecting precision is high, the reliability is good, and the service life is long.

Description

technical field [0001] The invention relates to a pantograph state detection device for a locomotive, in particular to an on-line detection device for the pantograph contact pressure of a railway locomotive. Background technique [0002] In recent years, high-speed electrified railways have developed rapidly in many countries, and a lot of research work has been carried out on high-speed electrified railways in my country. In the high-speed electrified railway system, it is necessary to maintain a stable current receiving state. Therefore, it is required to have a certain contact pressure between the pantograph and the contact wire: when the contact pressure is too small, it is easy to cause off-line, that is, the pantograph is separated from the contact wire and an arc is generated; when the contact pressure is too high, the lift of the contact wire is too large , so that the contact wire is partially bent, causing fatigue damage to the contact wire, and at the same time i...

Problems solved by technology

This method can detect the contact pressure of the pantograph at any point on the catenary, but it also has the following disadvantages: 1. The installed sensor is exposed to the air, the working environment is harsh, easy to damage, low reliability, and the detection accuracy It is also affected; 2. The installed sensors are close to the high-voltage catenary, which requires high insulation and anti-interference capabilities and is expensive; 3. It is necessary to install corresponding equipment on each pantograph of all trains, and the number of sensors required huge, expensive

[0005] At present, the actual measurement data of the pantograph-catenary contact pressure in my country is very lacking. The data in this area mainly come from Germany, France, Japan and other countries. my country's introduction of appropriate catenary suspension system is not conducive to my country's adjustment of railway development
