The utility model discloses a ground interception type braking device for a rail train, belongs to the field of braking of wheel-rail trains, and aims to solve the problem of low utilization rate of regenerative braking energy of subway trains and high-speed rail trains and solve the problem of the absence of the braking energy regeneration of internal combustion locomotives. According to the technical schemes of the invention, two long air cylinders are arranged on each of the two sides of a rail; a collision handle extends out of each of the two sides of a train and collides with buffers onthe two sides, thrust is transmitted to pistons through the buffers, the pistons are pushed to compress gas in the cylinders, and the gas enters a pressure container and is stored; and therefore, therecovery of energy can be realized. When the device is started, the pistons and piston rods return to starting points, second collision handles stretch out of the train to make contact with the ends of the buffers, valves are opened, the gas flows out of the pressure container to enter the air cylinders, the pistons are pushed to advance, thrust is transmitted to the train, the train is pushed toadvance; and the secondary utilization of braking energy is achieved, and t energy conservation and emission reduction are achieved.
一种用于轨道列车地面拦截式制动装置,属于轮轨列车的制动领域,本装置能解决地铁列车,高铁列车再生制动能量利用率较低的问题,能解决内燃机车没有制动能量再生的问题。解决的方案是,在铁轨的两侧各布置一个长的气缸,列车的两侧各伸出一个撞柄,先同两侧的缓冲器相撞,推力经缓冲器传递到活塞上,推动活塞压缩缸内气体,气体进入压力容器,并留存。实现了能量的回收。当启动时,活塞和活塞杆已回到起点,列车伸出第2个撞柄和缓冲器的端部接触,打开阀门,气体从压力容器中流出进入气缸中,推动活塞前进,推力通过传递到列车上,推动列车前进,实现了制动能量的二次利用,达到节能减排的效果。
