Abstract

The utility model provides an automatic safety stop and barrier clearing system and the corresponding methods in the unsupervised crossings. Control wires of the control mechanism in the system are connected to an alarm device, a car-hindering device and a control circuit of a transmission device. During use, a sensor of the control mechanism works in coordination with railroad lines, which receives the train driving signals. The transmission band is installed between the rails or at the sides of the rails. The exterior side of the transmission band is equipped with isolation belts and the car-hindering device is provided outside the isolation belts. The caution signal device of the caution and alarm mechanism is positioned appropriately and when the train drives into the crossing, the control mechanism sends out instruction signals and enables the caution and alarm mechanism to emit sounds, light signal reminding the vehicle or the passersby. The car-hindering device is in the car-hindering status after the start-up, which stops the cars and passersby from entering the crossing. The transmission band clears the cars and other barriers in the crossing so as to ensure that cars are hindered and barriers are cleared, which prevents the accidents from occurring.

Description

Unattended railway crossing's automatic vehicle blocking and obstacle eliminating system

Technical field

The utility model relates to a kind of signal indication of railway crossing, system ensemble of reporting to the police, holding up traffic and removing obstacles automatically of being mainly used in.

Background technology

Along with advancing by leaps and bounds of modern times construction, railway, road transport is huge to be increased, train running speed increases substantially, therefore at present although be provided with the caution alarm device at the level crossing of unattended railway and road, but when motor line sails to flame-out stagnation of movement in the road junction, when fault can not in time be got rid of, major traffic accidents very easily take place when running into train and driving into the road junction, chaufeur also takes place in addition often for racing against time, or do not notice alerting signal, behind the warning facilities signal that sends that No entry, still drive to sail into the by force phenomenon at road junction, accident with the train collision very easily takes place, therefore need a kind ofly when being reported to the police in train approaching road junction, can also remove self-propelled vehicle and other objects automatically at the road junction in, and the self-propelled vehicle outside the prevention road junction and pedestrian enter the facility at road junction, eliminates accident potential.

The utility model content

For not having, the caution warning system that overcomes unsupervised crossing under the prior art do not hold up traffic automatically and the defective of the ability of removing obstacles, reduce accident potential, the utility model provides a kind of unattended railway crossing's automatic vehicle blocking and obstacle eliminating system, use this system can be when train approaching road junction with the road junction on self-propelled vehicle or other objects of stagnation of movement shift out the road junction, and stop self-propelled vehicle, pedestrian and other vehicles outside the road junction to enter the road junction automatically, avoid colliding with train.

The technical scheme that the utility model solves the above-mentioned technological deficiency of prior art is: unattended railway crossing's automatic vehicle blocking and obstacle eliminating system comprise warning alarm mechanism, stop device, conveyer mechanism and control mechanism, described control mechanism is provided with the train vibration influence signal sensor, and its control line connects the control circuit of warning alarm mechanism, stop device and connecting gear respectively.

The using method of this system is: the train vibration influence signal sensor matches with railway line, accepts and sends the train vibration influence signal to control mechanism; Conveyer mechanism is installed between the rail in the level crossing of railway and road and rail both sides, reserves the gap that can supply train wheel to pass through between belt conveyor and the rail; In coming to the whereabouts road surface stop device being set of both sides, road junction road, the direction of holding up traffic leaves insulation strip for the direction to the road junction between stop device and the belt conveyor, and the stop device outside can also be provided with road surface deceleration stub; The Warning light of warning alarm mechanism and/or loud speaker are arranged on the position that can see and/or hear.

The principle of work of this system is: when train travels on railway, sensing device imports the train vibration influence signal into control mechanism, arrive the distance range of setting when train, control mechanism promptly sends control signal to warning alarm mechanism, stop device and conveyer mechanism, make these mechanism actions: wherein warning alarm mechanism sends signals such as sound, light and points out train approaching road junction to on-road vehicle and pedestrian, forbid that vehicle and pedestrian enter the road junction, should leave immediately in the road junction; Stop device is blocking state after starting, and stops vehicle and pedestrian outside the road junction to enter the road junction; The conveyer mechanism of rail and rail both sides starts, and the vehicle on the belt conveyor, personnel and other all objects are removed, and delivers to insulation strip, and the vehicle and the pedestrian that enter insulation strip can cross stop device from the inboard, continues outwards to advance; The effect of deceleration stub is that vehicle is slowed down when driving towards the road junction, avoids hot-short to impact and the breaking-up retarder; After train sailed out of the road junction, control mechanism sent new control signal, and warning alarm mechanism, stop device mechanism and belt mechanism reset, and the road junction is open-minded.

Because each mechanism in the system that the utility model provides cooperatively interacts, when driving towards the road junction, train not only can send the caution alarm signal as existing caution warning system, make vehicle and pedestrian initiatively leave the level crossing, and the road junction that enters that can stop vehicle and pedestrian automatically, vehicle, pedestrian and other objects that will be trapped in automatically on the road junction are removed from the road junction, avoided that vehicle is flame-out, goods comes off or danger that other accidents and human element cause, eliminated vehicle, pedestrian or other objects at the road junction with the train collision may.
