Problems solved by technology

Due to the constraints of various factors, the distance between the structure of the high-speed rail station building and the train is very limited, often less than 1m, which poses a severe challenge to the development of a reliable and efficient derailment train impact protection device

Embodiment Construction

[0012] Principle of the present invention, structure and concrete implementation will be further described below in conjunction with accompanying drawing:

[0013] The protective device consists of four lines of defense, the first line of defense: wheel guard rail; the second line of defense: protective retaining wall; the third line of defense: energy-absorbing block; the fourth line of defense: protective collar.

[0014] The first line of defense: a traditional guard rail 4 is set in the middle of the track 3 on the side of the column 10 of the station building. For low-speed arrival and departure trains (below 40km / h), if the train accidentally derails, the wheels on one side will be guarded. The rail 4 is stuck, the wheel on the other side is on the sleeper 2, the car body is slightly inclined to the column, and the train slides out of the range of the station column 10 under the guidance of the wheel guard rail 4, so that no collision will occur and basically no damage wi...

Abstract

A train derail impact protecting device based on multiple defending lines belongs to the technical field of train operation safety protection. A first defending line, a second defending line, a third defending line and a fourth defending line, namely a wheel protecting rail, a protecting retaining wall, an energy absorbing retaining block and a protecting hoop are sequentially disposed in a small space to allow the four defending lines to be integrated organically. Safety of station buildings under impact can be improved, damage of a derailed train and people in the train can be relieved to the greatest extent, safety of the station buildings and people therein is guaranteed, and good practicability and flexibility are achieved.

Description

technical field [0001] The invention relates to a train derailment impact protection device, which belongs to the technical field of train operation safety protection. Background technique [0002] In recent years, my country's high-speed railway construction has achieved rapid development. However, derailment accidents have always been an important problem that cannot be ignored in the development of railways. Due to excessive speed, unreasonable railway protection measures, bad weather conditions and problems of the train itself, train derailment accidents in various countries are common, which may lead to a large number of casualties and property losses. Especially for high-speed rail vehicles, due to their high speed, once they derail and collide with surrounding buildings, it will lead to more serious secondary disasters. A typical example is that in 2005, an express train on the JR Fukuchiyama Line from Takarazuka to Gakuken did not slow down on the curve, causing th...
