Problems solved by technology

[0002] In order to prevent the derailment caused by the train speed too fast, it is necessary to maintain the speed of the train within a certain speed. Because the inertia of the train is too large, the ordinary deceleration device is not suitable for the train, and the deceleration process of the train is often a comparison. It is a long process. The existing deceleration device weakens the deceleration effect under long-term braking friction, and the deceleration device is damaged due to excessive speed during the deceleration process. This equipment effectively solves this problem

Abstract

The invention discloses a speed limiting device for a railway train and a method for using the device. The device comprises a plurality of platforms fixed under the train. A medium speed reduction chamber is fixedly arranged in that travel platform. The front and rear sides of the medium speed reduction chamber are provided with front and rear symmetrical side speed reduction chambers. A left-right symmetrical travel shaft is arranged in that rotating medium speed reduction chamber. The device is simple in structure and convenient to use, and adopts multiple-channel speed reduction devices which work at the same time to slow the train down and to increase the train speed reduction rate. When the speed of the train is too high, buffer and switching equipment is added into the speed reduction device, so that the speed reduction device can be effectively protected from being worn or even damaged without reducing the efficiency of the train speed reduction, the service life of the speed reduction device is effectively prolonged, and the reliability of the speed reduction device is also increased.

Description

technical field [0001] The invention relates to the field of trains, in particular to a speed limiting device for railway trains and a method for using the same. Background technique [0002] In order to prevent the derailment caused by the train speed too fast, it is necessary to maintain the speed of the train within a certain speed. Because the inertia of the train is too large, the ordinary deceleration device is not suitable for the train, and the deceleration process of the train is often a comparison. In the long process, the existing deceleration device weakens the deceleration effect under long-term braking friction, and the deceleration device is damaged due to excessive speed during the deceleration process. This equipment effectively solves this problem. Contents of the invention [0003] The object of the present invention is to provide a railway train speed limiting device and its use method, which can overcome the above-mentioned defects of the prior art. ...
