Abstract

The invention discloses an air brake fault alarm device for a railway vehicle, which comprises a brake cylinder pressure sensor communicated with a brake cylinder, a train pipe pressure sensor connected with a train pipe, and an alarm system. A brake cylinder pressure switch and a train pipe pressure switch are arranged on the brake cylinder pressure sensor and the train pipe pressure sensor respectively, and can be contacted with corresponding normally closed joints A and B or normally open joints A and B respectively under the actions of the brake cylinder pressure sensor and the train pipe pressure sensor; and the alarm system, the train pipe pressure switch, the brake cylinder pressure switch, and a power supply form a loop. In the invention, the brake cylinder pressure sensor and the train pipe pressure sensor are used to detect the pressure when the air brake is in a working state, in the case of an abnormal pressure, an alarm circuit is powered on to give out an acoustic and optical alarm. Therefore, a train examiner is reminded of the fault and safe train traveling is ensured.

Description

technical field [0001] The invention relates to an air brake failure alarm device for railway vehicles. Background technique [0002] The air brake system is an essential part of a railway vehicle, and it is an important factor affecting safe driving. The air brake system of railway vehicles was not equipped with a fault alarm before, and the fault of the air brake can only be detected intuitively by human eyes. It is difficult to find hidden faults in a simple way, which affects driving safety and needs to be improved. Contents of the invention [0003] The object of the present invention is to provide a fault alarm device for air brakes for railway vehicles that can quickly and accurately diagnose typical faults of air brakes for railway vehicles and give an alarm in view of the above-mentioned problems. [0004] The technical solution of the present invention is realized as follows: an air brake fault alarm device for railway vehicles, characterized in that it includes...
