Abstract
The invention discloses an anti-explosion gate machine. The anti-explosion gate machine is characterized by comprising a handrail, a gate machine box, an air cylinder, a linkage mechanism, an electromagnetic valve, signal lines and a control circuit board, the air cylinder, the linkage mechanism and the electromagnetic are all arranged inside the gate machine box, the handrail is mounted at the top of the gate machine box, one end of the handrail is connected with the linkage mechanism which is connected with the air cylinder, the air cylinder is connected with the electromagnetic valve which is connected to the control circuit board through the signal lines, and the control circuit board is mounted in a control room. An outdoor gate machine portion does not adopt any circuit structure, and ascending and descending of the handrail are realized through controlling of the anti-explosion double-coil electromagnetic valve and driving of the double-action air cylinder, so that potential safety hazards caused by electric sparks are thoroughly eradicated, and the anti-explosion gate machine is higher in safety performance when compared with similar products.
Description
Technical field
The present invention relates to explosion-proof dynamo-electric product technical field, particularly a kind of explosion-proof gate.
Background technology
On the doorway of large-scale plant area, be substantially all provided with for stoping and control the gate equipment of vehicle pass-through.Yet, in some special plant areas, the equipment of on-site is had to certain explosion-proof index request, particularly, for the plant environment of the explosive mixture that exists II category-A or II category-B gas and air to form, must use the good electronic product of explosion-proof performance, gate equipment is also like this.Common gate equipment does not possess explosion prevention function, has production hidden danger, therefore, is not suitable with at these plant environments and uses.
Nowadays on market, also occurred that some possess the gate equipment of explosion prevention function, the patent application document that for example patent No. is 201220011721.9 discloses a kind of explosion-proof barrier machine, it by arranging fire-proof motor on worm gear case, and explosion-proof electric control box is set in Road barricade case reaches corresponding requirement of explosion proof, yet, because being still, its inside adopted electric machine structure, and it can not fundamentally go to stop the unexpected situation that electric spark produces, in fact, still there is certain potential safety hazard.
Summary of the invention
The object of the invention is: propose a kind of explosion-proof gate, its lock cabinet inside does not adopt any device that may produce electric spark, therefore, fundamentally stopped the potential safety hazard brought by electric spark, it is preferably is having the plant area of specific (special) requirements to use to explosion-proof.
The technical solution adopted for the present invention to solve the technical problems is:
A gate, comprises railing, gate case, cylinder, interlinked mechanism, electromagnetic valve, holding wire and control circuit board; Described cylinder, interlinked mechanism and electromagnetic valve are all arranged on lock cabinet inside, and described railing is arranged on ，Qie one end, gate box top and is connected with described interlinked mechanism, and are driven and be take rotating shaft and do lever elevating movement as fulcrum by described interlinked mechanism; Described interlinked mechanism is connected with described cylinder, and by described cylinder controlled motion; Described cylinder is connected with described electromagnetic valve, and by described solenoid control, described electromagnetic valve is connected to described control circuit board by holding wire, and is controlled by described control circuit board, and described control circuit board is arranged in control room.
Further, described electromagnetic valve adopts explosion-proof Double coil electromagnetic valve.
Further, described cylinder adopts double-acting cylinder.
Further, described interlinked mechanism adopts leverage or fixed pulley mechanism.
Further, described control circuit board is pcb board, and is respectively equipped with liter, stops, falls three buttons above.
Further, the source of the gas input of described electromagnetic valve is connected to instrument air.
The invention has the beneficial effects as follows: outdoor gate part of the present invention does not adopt any circuit structure, it realizes the elevating movement of railing by the control of explosion-proof Double coil electromagnetic valve and the driving of double-acting cylinder, thoroughly stopped the potential safety hazard of bringing because of electric spark, its security performance of like product of comparing is higher.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
A outdoor area, B room area;
1-railing, 2 gate casees, 3 interlinked mechanisms, 4 double-acting cylinders, 5 explosion-proof Double coil electromagnetic valves, 6 holding wires, 7 control circuit boards, 8 instrument airs.
The specific embodiment
As shown in Figure 1, having the plant area of special requirement of explosion proof, gate case 2 and the railing 1 of explosion-proof gate are arranged in outdoor area A, and control circuit board 7 is arranged in room area B; Gate case 2 is equipped with interlinked mechanism 3, double-acting cylinder 4 and explosion-proof Double coil electromagnetic valve 5; Wherein, interlinked mechanism 3 is connected with one end of railing 1, controls railing 1 and take rotating shaft and move up and down as fulcrum.Double-acting cylinder 4 is connected with interlinked mechanism 3, and by the effect of cylinder, controls the motion of interlinked mechanism 3, and double-acting cylinder 4 is controlled its action by explosion-proof Double coil electromagnetic valve 5; Explosion-proof Double coil electromagnetic valve 5 is connected with control circuit board 7 by holding wire 6, and controls its on off state by control circuit board 7; The source of the gas input of last explosion-proof Double coil electromagnetic valve 5 is connected with instrument air 8.
Control circuit board 7 in of the present invention is pcb board, and is respectively equipped with above liter, stops, falls three buttons, is respectively used to control three kinds of motion states of railing.
Interlinked mechanism in the present invention adopts leverage or fixed pulley mechanism to realize.
Railing in the present invention can rise to plumbness by level.
Inventor is in when design, circuit part of the present invention is that control circuit board 7 is arranged on indoor, and is connected to outdoor gate part by holding wire 6, in outdoor gate part, do not comprise any circuit, thereby the generation of fundamentally having stopped electric spark, has effectively prevented potential safety hazard.
The course of work of the present invention: when having vehicle to enter, in control room, press the rising button on control circuit board 7, signal is sent to explosion-proof Double coil electromagnetic valve 5 by holding wire 6, explosion-proof Double coil electromagnetic valve 5 is controlled double-acting cylinder 4, by interlinked mechanism 3, controlling railing 1 again rises, in uphill process, can press at any time the stop button on control circuit board 7, stop at any time the motion of railing 1, after vehicle passes through, press the decline button on control circuit board 7, control again railing 1 and drop to level, in this process, also can press at any time stop button on control circuit board 7 and stop at any time the motion of railing 1.
The above-described preferred embodiment of utilizing describes the present invention in detail, but not limits the scope of the invention.Those skilled in the art can make trickle change and adjustment by reading after the present invention, and the main idea of the present invention of will can yet be regarded as place, does not also depart from the spirit and scope of the present invention.
