Railway vehicle emergency stopping device

Abstract

The invention relates to a railway vehicle emergency stopping device which comprises a train pressure control switch, a controller and a shunting radio station DT, wherein the train pressure control switch is provided with a No.1 pressure control switch K1 and a No.2 pressure control switch K2; the No.1 pressure control switch K1 is provided with normally open contacts S1 and S2; the No.2 pressure control switch K2 is provided with normally open contacts S3 and S4; the normally open contacts S1 and S2 are connected in series; and the normally open contacts S3 and S4 are connected in series. The controller arranged outside the track comprises a power circuit, an emergency stopping signal circuit, a voice circuit, a power reset circuit, a relay delay reset circuit and a voice sending device; all circuits of the controller are powered by the power circuit, and consist of a group of relays, a group of delay relays and a voice plate; and the controller outputs a warning voice signal, an emergency braking signal and a reset signal according to the signals of the two pressure control switches. The railway vehicle emergency stopping device provided by the invention is firm, durable, fireproof, explosion-proof, waterproof and temperature-resistant, and can stably send a normally open or normally closed switch signal.

Description

technical field [0001] The invention relates to a detection and alarm device for a railway vehicle device, in particular to an emergency stop device for a railway vehicle used for detecting the approaching and arriving states of a train and providing signals. Background technique [0002] At present, when the railway vehicles are shunting at the end line or the soil block, the shunting personnel are in command. When the train approaches the end of the railroad track or the soil block, the shunting personnel immediately press the "emergency stop button" on the hand-held radio to transmit the emergency brake of the train. However, sometimes when the train approaches the end line of the railway track or the earth block, it does not attract the attention of the shunting personnel or the train driver, causing the train to go out of the end line or hit the earth block. Contents of the invention [0003] The purpose of the present invention is to improve and innovate on the s...
