Problems solved by technology
[0003] In actual use, often due to the high speed of the train and the large mass of the carriage itself, its momentum is large, and it takes a long braking distance to stop it. How to make the wheel stopper stop faster and better? To stop the incoming train car, further improve the structure of the wheel stopper, increase the friction between the wheel and the track, and improve the safety factor of the brake, which is a problem to be solved

The invention relates to the field of railway track auxiliary equipment, and in particular to a stress self-clamping railway track wheel stopper that comprises a wheel stopper body and a self-clampingdevice. The wheel stopper body comprises a wheel stopper head and a wheel stopper bottom. The self-clamping device is arranged in the wheel stopper head, and comprises a base, a lining rod, an outersleeve and a clamping rod assembly, wherein the base is fixedly arranged in the wheel stopper head, the lining rod is arranged on the base, the outer sleeve is of a hollow structure and is arranged outside the lining rod in a sleeving mode, and the clamping rod assembly is arranged on the outer sleeve; when a wheel makes contact with the wheel stopper body, the wheel stopper body is pushed to moveforwards along with the train wheel, rolling friction is changed into sliding friction, and the train wheel is braked to stop. When the train wheel touches the outer sleeve, the stress of the train wheel is lowered to drive the clamping rod assembly to clamp towards the middle, so that the train wheel can stop more quickly; when the train wheel presses the outer sleeve, the clamping rod assemblyclamps the rail. The equipment can effectively prevent the train from sliding and is high in safety coefficient.
Description
technical field [0001] The invention relates to the field of railway track auxiliary equipment, in particular to a stress self-clamping railway track wheel stopper. Background technique [0002] Railway track wheel stopper, also known as iron shoes, is a special equipment set up to prevent parked locomotives and vehicles from slipping during railway shunting operations. At present, the iron shoes used on railway stations in our country are all bilaterally made Moving iron shoes are composed of two parts: the bottom and the head. Bottom: After the wheel steps on the sole of the shoe, use the head to block the wheel, so that the shoe and the wheel slide together to act as a brake. The head part consists of two parts, the toe cap and the baffle. The so-called iron shoe braking is to place iron shoes on one or two heels of the steel rails. After pressing the iron shoes on the rolling wheel, it slides along the rails. The friction between the wheels and rails changes from rolli...
