The invention discloses a method for detecting the vehicle entering speed of an anti-slip parking device in a railway yard, a brake rail friction surface distance detection device is arranged at the entrance end of the anti-slip parking device, when a rolling vehicle enters the entrance of the anti-slip parking device, the anti-slip parking device is in a braking state, the brake rail friction surface distance is slightly greater than the inner side distance of a vehicle wheel set, when the vehicle wheel set enters the anti-slip parking device, brake rails on the two sides are pressed to move towards the inner side and keep the same distance with the inner sides of the wheels, the process is called as the deformation process of the brake rails, and the time of the deformation process is in direct proportion to the speed of the vehicle entering the entrance. The process is detected and the data are substituted into V < in > = K * D/(T1-T0), so that the entering speed of the vehicle can be judged. The method is reasonable and simple in structural design, low in cost, easy to implement and suitable for popularization and application.

    本发明公开了一种检测铁路站场防溜停车器车辆入口速度的方法,在防溜停车器入口端安装制动轨摩擦面距离检测装置,当溜放车辆进入防溜停车器入口时,防溜停车器处于制动状态,其制动轨摩擦面距离要略大于车辆轮对的内侧距,当车辆轮对进入防溜停车器后会压迫两边制动轨向内侧移动并保持与车轮内侧距相等,这个过程我们称之为制动轨的形变过程,这个形变过程的时间与车辆入口速度成正比。侦测这一过程并将数据代入V入=K*D/(T1‑T0)就可判定车辆的入口速度。本发明结构设计合理且简单,成本低,易于实现,适合推广应用。
