Shunting anti-crowding turnout automatic control device and turnout anti-crowding locomotive self-stop system

Abstract

The invention provides a shunting turnout crushing prevention automatic control device which comprises a photosensor, a controller, a magnetic control parking device and a photovoltaic power supply which are arranged on an annunciator. When the photosensor senses that a turnout is in a locked state, a signal is output to the controller, the controller controls a strong magnet of the magnetic control parking device to move toward the direction close to steel rails, a forcedly operating locomotive is urgently vented and the automatic parking is implemented, so that the accident of crushing the turnout by the locomotive; and when the photosensor senses that the turnout is in a switching-on state, a signal is output to the controller and the controller controls the strong magnet of the magnetic control parking device to move toward the direction far away from the steel rails, so that the normal passing of the locomotive is not influenced. A locomotive automatic stop system matched with the shunting turnout crushing prevention automatic control device for use comprises a magnetic induction sensor, a locomotive monitoring device (LKj), a brake and the like which are arranged on the locomotive. The shunting turnout crushing prevention automatic control device and the locomotive automatic stop system have the advantages of effectively preventing the accident of crushing the turnout by the locomotive, which is caused by the misjudgment and the blind action of a driver and providing the reliable guarantee for the safety production.

Description

technical field [0001] The invention relates to a safety device suitable for safe shunting of locomotives in railway locomotive depots and station yards to prevent locomotives from crushing turnouts, in particular to a shunting anti-crowding device and a turnout anti-crowding system. Background technique [0002] At present, the locomotive monitoring and monitoring device (LKJ) of my country's freight traction locomotives plays an important role in ensuring the safety of locomotive traffic, but in complex and key areas of the line: in stations, marshalling yards, and locomotive depots, due to complex turnouts and complicated lines Due to some circuit reasons (serious oil and water pollution, insufficient line length, complex interlocking relationship, etc.), it is impossible to install the track circuit code sending device. Make the above-mentioned shunting lines all be in the blind zone of signal sending, and make the locomotive monitoring device (LKJ) useless. For this rea...

Problems solved by technology

However, due to driver fatigue, night work, rainy and foggy weather, complex line conditions or poor lookout conditions, etc., the driver may misjudge and drive the locomotive to forcibly pass the "locked" turnout, resulting in a turnout accident and endangering production safety. cause hidden dangers and economic losses

[0004] Since this kind of accident is a systematic (related to management, line, turnout, locomotive, driver, time, weather and other factors) accident, and there is no technical and equipment guarantee, the current situation of train accidents being effectively curbed However, accidents of "squeezing, colliding, and falling off" of locomotives still occur frequently during shunting operations, which has become a bottleneck restricting transportation safety
