Abstract
The utility model discloses a novel explosion-proof handrail machine which is characterized by comprising a handrail, a gate box, a cylinder, a linkage mechanism, an electromagnetic valve, signal lines and a control circuit board. The cylinder, the linkage mechanism and the electromagnetic valve are arranged inside the gate box, the handrail is mounted on the top of the gate box, and one end of the handrail is connected with the linkage mechanism; the linkage mechanism is connected with the cylinder; the cylinder is connected with the electromagnetic valve; the electromagnetic valve is connected to the control circuit board by the signal lines; the control circuit board is mounted in a control room. The novel explosion-proof handrail machine has the advantages that an outdoor portion of the novel explosion-proof handrail machine is free of circuit structures, the handrail ascends and descends under the control effect of the explosion-proof double-coil electromagnetic valve and the driving effect of the double-acting cylinder, accordingly, potential safety hazards due to electric spark can be completely eradicated, and the safety performance of the novel explosion-proof handrail machine is high as compared with like products.
Description
Technical field
The utility model relates to explosion-proof dynamo-electric product technical field, particularly a kind of new type explosion proof barrier machine.
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.
Utility model content
The purpose of this utility model is: propose a kind of new type explosion proof barrier machine, 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 utility model solves the technical scheme that its technical problem adopts:
A new type explosion proof barrier machine, comprises railing, gate case, cylinder, link gear, electromagnetic valve, holding wire and control circuit board; Described cylinder, link gear and electromagnetic valve are all arranged on lock cabinet inside, and described railing is arranged on gate box top, and one end is connected with described link gear, and are driven and be take rotating shaft and do lever elevating movement as fulcrum by described link gear; Described link gear 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 described 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 link gear 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 beneficial effects of the utility model are: outdoor section of the present utility model 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 the utility model structural representation.
A-outdoor area, B-room area;
1-railing, 2-gate case, 3-link gear, 4-double-acting cylinder, the explosion-proof Double coil electromagnetic valve of 5-, 6-holding wire, 7-control circuit board, 8-instrument air.
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 barrier machine are arranged in outdoor area A, and control circuit board 7 is arranged in room area B; Gate case 2 is equipped with link gear 3, double-acting cylinder 4 and explosion-proof Double coil electromagnetic valve 5; Wherein, link gear 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 link gear 3, and by the effect of cylinder, controls the motion of link gear 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.
Link gear in the utility model adopts leverage or fixed pulley mechanism to realize.
Railing in the utility model can rise to plumbness by level.
Utility model people is in when design, circuit part of the present utility model is that control circuit board 7 is arranged on indoor, and is connected to outdoor gate part by holding wire 6, in outdoor section, 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 utility model: 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 link gear 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 utility model in detail, and unrestricted scope of the present utility model.Those skilled in the art can make trickle change and adjustment by reading after the utility model, and the main idea of the present utility model of will can yet be regarded as place, does not also depart from spirit and scope of the present utility model.
