城市轨道交通线路终端防护设备——DDCQ2型滑移式缓冲挡车器

The Protection Equipment of Urban Rapid Rail Transit Railway Terminal

在城市快速轨道交通线路终端设置防护设备是十分必要的。本文介绍了新型的滑移式缓冲挡车器的设计技术条件及新的设计方案 ,研究了挡车器的制动力及轨道车辆在撞击挡车器瞬间的撞击力 ,讨论了挡车器是否会损坏轨道车辆等问题。

In the past few years, accidents such as train out of control occurred in shunting work of Shanghia and Beijing subways, when the car dashed on the stop buffer and was damaged. Therefore, it's urgently necessary to set up a system of protection equipment on terminal track of the urban rapid rail transit railway. This article studies a new type technology condition of the desgin for sliding buffer and makes a new desgin plan. It also throws light on the problems that whether the car is damaged or not, when the car is braking or dashing on the buffer under the power force.
