Abstract
A vehicle barrier able to prevent the vehicle from being beaten by its barrier beam is composed of manipulator, driver, controller, transmission unit, proximity switch and barrier beam. Said barrier beam may be in vertical state for allowing vehicle to pass through it or in horizontal state to stop the vehicle. It has also a sensor unit to detect if there is a vehicle under the barrier beam or close to it. If there is, the downward movement of barrier beam is stopped and it moves upward.
Description
Technical field
The present invention relates to a kind of car lug that freeway toll station, parking lot etc. are located, particularly a kind of vehicle barrier device of being used for.
Background technology
Common car lug comprises drive unit, transmission device and a pin.A shortcoming of this alley stopping device is, if pin has vehicle to be positioned under the pin when falling just, pin still continues to fall, and causes vehicle damage.
Someone had once invented the vehicle barrier device.Typical vehicle barrier device is disclosed in CN2278013Y and US4531325.A common feature of these vehicle barrier devices is, a crashproof connecting lever is housed on the pin, and this connecting lever and pin main body are hinged.Therefore, connecting lever can rotate up around pin joint with respect to the pin main body.Like this, connecting lever at a touch vehicle will rotate up with respect to the pin main body, thereby can not pound onboard heavyly.But this vehicle barrier device still can be run into vehicle, and vehicle is caused certain damage.
The content of invention
An object of the present invention is to provide a kind of vehicle barrier device, when the pin of this car lug fell, if vehicle is arranged below the pin, pin can stop automatically, thereby prevents from vehicle is smashed.
Vehicle barrier device of the present invention comprises operating means, drive unit, transmission device and pin, also comprises a sensing unit and a control device.Described operating means is used for the manual operation car lug, drive unit provides power for car lug, the transmission of power that transmission device provides drive unit is to pin, make pin in perpendicular horizontal level and stand up position between move, block vehicle at horizontal level, at stand up position clearance vehicle.Sensing unit be used for when pin falls detecting pin under whether vehicle is arranged or whether has been about to vehicle and occur, when there is vehicle the pin below or has been about to vehicle, sensing unit sends signal to control device, after control device receives this signal, during the control pin, sensing unit sends signal to control device, after control device receives this signal, the control pin stops to fall, and turns to and move upward.
Preferably, described sensing unit comprises a radiating portion and a receiving unit, more preferably an infrared emission part and an infrared receiving unit.These two parts are arranged on below the bar, its line be positioned at pin under the certain altitude place.Like this, when there not being vehicle to be positioned at pin following time, infrared receiving unit receives from infrared emission part emitted light beams, does not send instructions to control device, and pin normally moves.And when there was vehicle the pin below or is about to vehicle occur, the light that partly sends from infrared emission was blocked, and infrared receiving unit does not receive infrared rays.In this case, sensing unit sends a signal to control device, control device control pin is turned to from the motion of falling move upward.
The another kind of form of implementation of sensing unit is a ground induction coil.That is, a ground induction coil is set on the ground below pin, when vehicle appearred in the pin below, ground induction coil sent signal to control device, control device control pin is turned to from the motion of falling move upward.
In a preferred embodiment, control device comprises a Schmidt trigger, a solid-state relay and a single-chip microcomputer.The signal that sends from sensing unit is through the Schmidt trigger shaping, delivers to single-chip microcomputer after oppositely to handle, and produces signal, the control solid-state relay, thus the control transmission mechanism stops at once by the operation of upright position to horizontal level pin, and inverted running, thereby prevented to pound car.
Description of drawings
Fig. 1 is the front view of a form of implementation of vehicle barrier device of the present invention.
Fig. 2 is a vertical view of vehicle barrier device of the present invention shown in Figure 1.
Fig. 3 is the workflow diagram of vehicle barrier device of the present invention.
Fig. 4 is a vehicle barrier device of the present invention flow chart when adopting Hydraulic Power Transmission System.
The specific embodiment
As depicted in figs. 1 and 2, vehicle barrier device of the present invention comprises 1, one pin of a car lug casing 2, a pillar 3.When pillar 3 is positioned at pin and is horizontal near the far-end of pin.The radiating portion 4 of sensing unit is set on car lug casing 1, the receiving unit 5 of sensing unit is set on pin pillar 3, as shown in Figure 2, on direction of traffic W, radiating portion 4 and receiving unit 5 are positioned at the upstream of pin 2.In the dropping process of pin 2, sensing unit receiving unit 5 receives when vehicle occurring on 5 the line, the signal that sends, and for example infrared rays is blocked, and receiving unit 5 can not receive the light that radiating portion 4 sends, and at this moment, receiving unit 5 sends signal to control device.
Fig. 3 illustrates the workflow diagram of vehicle barrier device of the present invention.As shown in the figure, the operator sends instruction up, descending or that stop by mouse, and this instruction is transported to the control cabinet.The control cabinet is according to this instruction control transmission mechanism.Send stopping signal to control cabinet when proximity Hall switch reaches the upright position or reaches the straight position of water when descending when detecting pin up, make pin out of service.In the descending process of pin, when if the light that the radiating portion of infrared sensing unit sends to receiving unit is subjected to blocking, infrared sensor sends signal to the control cabinet, according to this signal, control cabinet control pin stops downward movement, and reverse upstroke.
Also can adopt a sensing unit radiating portion and a sensing unit receiving unit in the ground induction coil replacement previous embodiment.Ground induction coil is arranged on the line of sensing unit radiating portion and sensing unit receiving unit among the last embodiment.When on the local sense coil vehicle being arranged, ground induction coil sends signal to the control cabinet, makes control cabinet control pin turn to upstroke from downward movement.
Fig. 4 is the workflow diagram when vehicle barrier device of the present invention combines with hydraulic drive.As can be seen from the figure, hydraulic transmission comprises a reversal valve, an A oil circuit and a B oil circuit, A, B two oil circuits respectively have a hydraulic control one-way valve, an oil cylinder, and it is up that the A oil circuit promotes pin, and it is descending that the B oil circuit promotes pin, the control cabinet is by the magnet control reversal valve, thereby control A is moved by road or B oil circuit, when the A oil circuit moves, and the pin upstroke, when the B oil circuit moves, the pin downward movement.
Those skilled in the art are easy to find out, also can adopt the mechanical type kind of drive in the present invention, and the sensing unit among the present invention and control device combined with the mechanical type transmission be easy to for the person of ordinary skill of the art realize, here repeat no more.
Control device can comprise a Schmidt trigger, a solid-state relay and a single-chip microcomputer.Sensing unit is handled to signal anti-phase single-chip microcomputer of delivering to after the Schmidt trigger shaping that control device sends, produce the signal of control solid-state relay, thereby the control transmission mechanism stops by the operation of upright position to horizontal level pin 2 at once, and makes inverted running.
Those skilled in the art is not difficult to find out that vehicle barrier device of the present invention can just make pin reverse before pin runs into vehicle, so just fundamentally avoided pin to pound car.
