Problems solved by technology
At present, the vehicle can only rely on its internal automatic control system or the driver's operation to achieve braking. Once the system fails or is improperly operated, it is easy to cause an accident
Therefore, the existing two types of equipment cannot be applied to EMUs

Embodiment Construction
[0022] according to Figure 1~7 The specific structure of the present invention will be described in detail. This electronically controlled wheel stopper includes parts such as a driver 7 and a brake, and also includes an upper shoe sensor 4. The upper shoe sensor 4 is composed of a wheel pedal 21, a pedal return spring 22, a pedal spring mandrel 23, a fixed seat 24, and a lower end cover 25. , Rail clamp 31 is formed, and fixed base 24 and lower end cover 25 are fastened by bolt, and fixed base 24 and rail clamp 31 are fastened on steel rail 9 bottoms by bolt. The wheel pedal 21 is a hollow cylinder with a chamfer at the bottom with a boss on the top, the pedal spring mandrel 23 is a cylinder with a boss at one end, and one end of the boss of the pedal spring mandrel 23 is limited in the lower end cover 25, The other end is inserted into the wheel pedal 21 and fastened on the top of the wheel pedal 21 by bolts. A pedal return spring 22 sleeved outside the pedal spring mandre...

Disclosed is an electric-control wheel-stopping train-blocking device. The electric-control wheel-stopping train-blocking device avoids train accidents caused by brake failure or the inappropriate operation of a driver in the prior art, and comprises an actuator and a brake. According to the technical scheme, the electric-control wheel-stopping train-blocking device further comprises an upper shoe sensor, wherein the upper shoe sensor is composed of a wheel pedal, a pedal reset spring, a pedal spring mandrel, a fixing seat, a lower end cover and a rail clip, the fixing seat and the lower end cover are fastened through a bolt, and the fixing seat and the rail clip are fastened at the bottom of a steel rail through a bolt. After the wheel pedal is pressed downwards, a switch guide pillar is pushed by the chamfering at the bottom of the wheel pedal to horizontally move towards the direction of a switch base. The electric-control wheel-stopping train-blocking device is ingenious and reasonable in design, a wheel-stopping device can be accurately placed between two shafts of a steering frame, and braking ability can be freely arranged according to requirements. The electric-control wheel-stopping train-blocking device has a very important significance in guaranteeing safety of motor train unit maintenance inside a garage, preparation, maintenance and staying.
Description
technical field [0001] The invention belongs to safety equipment for railway shunting operations, in particular to an electronically controlled wheel stopper specially used for railway vehicles such as EMUs, subways, light rails, etc. In other places, it is installed far away from the line terminal to prevent the vehicle from slipping away naturally, and it is located near the line terminal to prevent accidents caused by train brake failure or improper operation of the driver. Background technique [0002] With the vigorous development of my country's rail transportation industry, the number is increasing year by year. During the maintenance and repair process of trains in the warehouse, they basically have to drive to the end line, especially in the garage. The first car is very close to the line terminal. Mistakes can easily lead to accidents. There is also the possibility of natural slippage of the stationary train. [0003] At present, there are many kinds of car stoppe...
