Method for regulating speed of railway plane glide and preventing car overrunning in humping

Abstract

The invention relates to a method for simultaneously preventing hump overrunning and regulating the speed of railway plane glide operation. A clamp type retarder is arranged at an inlet of a railway classification yard tail track, a dowty retarder is arranged in a section from a target shooting terminal of the clamp type retarder to a grade change point, a speed measuring radar is arranged between a shunting signal and the clamp type retarder, and a retarder section track circuit and a clamp type retarder control circuit are arranged at the mounting position of the clamp type retarder. In railway classification yard plane glide operation and humping operation, the clamp type retarder, the speed measuring radar, the retarder section track circuit and the clamp type retarder control circuit are used for regulating the speed of railway cars and preventing the cars from overrunning the track. Operators can be decreased, the plane glide speed regulation efficiency of a railway classification yard is improved, potential safety hazards of the operation are decreased, flat shunting operation of the tail of the railway classification yard thoroughly breaks away from brake shoes, transportation safety is ensured, and labor productivity is improved.

Description

Technical field [0001] The invention relates to a method for regulating the speed of railway plane slides and preventing vehicles from slipping during hump slides, which is applied to the automatic speed regulation and anti-slip control of the plane slide operation at the rear of a railway freight marshalling station. Background technique [0002] The plane slipping and shunting operation at the rear of the railway marshalling yard (tailing yard) is a method that uses the kinetic energy of the locomotive to accelerate and push the vehicle forward, decoupling the forward vehicle, and at the same time decelerate the locomotive, and the vehicle continues to move forward (sliding) by using inertia. The opening position of the turnout enters the marshalling and shunting operation method of parking in different lanes (commonly known as the plane sliding operation). The moving vehicles entering the lane are connected with the existing vehicles staying in the lane at a speed below 3...

AI Technical Summary

Problems solved by technology

This method is prone to safety problems such as derailment caused by stuck shoes, collision caused by improper braking, and reversed iron shoes caused by forgetting to withdraw the iron shoes. At the same time, it will cause damage to the wheel tread.

; The loss of iron shoes has a serious safety hazard to the main line of the railway

Manually controlled iron shoe speed regulation cannot realize automatic coupling, which is inefficient

Iron shoe braking requires one or two experienced personnel to place the iron shoes at each lane at the end of the marshalling yard, and the labor efficiency is low
