[0043] Working principle:

[0044] The railway shunting anti-sliding automatic braking device is based on the cooperation of the electric sliding rail 11, the detection module, the communication module and the control module, and realizes the anti-sliding function through automatic positioning, precise clamping and buffer energy absorption. When working, the infrared sensor and the speed sensor in the detection module detect the current position, speed information and wheel state of the train in real time, and transmit the data to the control module through the wireless communication device and the data processing unit in the communication module. The control module receives and calculates the position, wheel diameter and running state of the train, sends instructions to the electric pulley in the electric sliding rail 11, drives the pulley to move along the sliding rail, thereby adjusts the relative position of the electric telescopic rod 12 and the limiting frame 14, and realizes the automatic positioning of the train wheels. After positioning, the control module sends a control signal to the servo motor 16 to drive the limiting wheel 17 to clamp the wooden block 13, and after the wooden block 13 is clamped by the limiting wheel 17, it is placed under the wheel to tightly adhere to the wheel with high friction and anti-skid texture, preventing the train from sliding due to inertia or external force. During clamping, the limiting frame 14 is connected with the electric telescopic rod 12 through the elastic buffer mechanism, the spring assembly provides buffer force to avoid damage to the device due to excessive clamping force, and the damper absorbs impact and vibration to improve stability. During the whole process, the control module dynamically adjusts the action of the servo motor 16 and the electric pulley according to the real-time data provided by the detection module, realizes the precise clamping and release of the wooden block 13, and ensures that the device adapts to the train shunting operation in different scenes.
