Energy self-supply type controllable stopping device

Abstract

The invention discloses a self energy resource controlled parking equipment,which comprises the following parts: decision rapid roof, support arm and brake beam, wherein the decision rapid roof is installed at the entrance end of parking car in front of the parking equipment; the spiro is at the outside of circuit stock rail; the support arm uses the inside and outside rail anchor to fix on the stock rail bottom and uses the bolt to fix; the brake beam snail is fixed on the support bolster; the hydraulic press is a closed hydraulic system which is integrated with hydraulic cylinder, plunger piston, reversing solenoid valve, one-way valve, accumulator, which can saves the generator, air pump, lubricant pump,accumulator,power cable,conduit line,adaptor and other external devices; when the parking equipment installs at the bottom of the classification track is use for as parking equipment, the normal condition is application position; the order is controlled by controlling building; the proof slide vehicle is carried out the automatic stopping which installs target section behind the goal application position exit; when parking equipment is used for goal brake, the normal condition is for alleviation position to carry out braking speed governing. The invention simplifies the structure, which uses widely.

Description

Technical field [0001] The invention relates to a self-energy controllable parking device for speed regulation or brake parking of rolling vehicles in a railway marshalling yard, and belongs to the technical field of railway marshalling yard speed regulation. Background technique [0002] At present, the speed control equipment used in the railway marshalling yard to adjust the speed or brake parking of rolling vehicles requires energy except for the retarder. Some use electric drive directly, and some use air pressure system or hydraulic system, all of which require motors. , Accumulators, oil pumps or air pumps, all need to connect pipelines and joints, need large-capacity transformers and lay power cables, etc., consume a lot of electric energy, large engineering volume, high cost, and difficult maintenance. Especially the hydraulic controllable parking devices used in China in recent years have too many joints, serious oil leakage, large power consumption, difficult to repair...

AI Technical Summary

Problems solved by technology

[0002] At present, the speed control equipment used in the railway marshalling yard for the speed control or brake parking of rolling vehicles requires energy except the deceleration top. Some directly use electric drive, and some use air pressure system or hydraulic system. , accumulators, oil pumps or air pumps, all need to connect pipelines and joints, need large-capacity transformers and lay power cables, etc., consume a lot of electric energy, the amount of work is large, the cost is high, and maintenance is difficult

Especially in recent years, the hydraulic controllable parking devices used in China have too many joints, serious oil leakage, large power consumption, difficult maintenance, and some cannot be used normally.

As a device for the purpose of braking protection, there are also disadvantages such as difficulty in speed measurement and the need to manually restore the brake once overspeed occurs.
