Fig. 2 is front view of the present utility model.
In figure: 1, suspension ring; 5, hold-down nut; 6, switch; 7, screw; 9, guide rod; 10, stage clip; 11, gland; 12, ball journal; 14, spring washer; 15, housing; 16, rivet; 17, nameplate groove; 18, cover plate; 19, packing seal.
The specific embodiment
In order to make of the present utility modelly to realize technological means, creation characteristic, reach object and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.
As shown in Fig. 1～2, a kind of coal piling sensor, comprise: housing 15, cover plate 18, guide rod 9, stage clip 10, gland 11, ball journal 12, switch 6, described housing 15 both sides are provided with closure plate, closure plate is fixing by hold-down nut 5, between hold-down nut 5 and housing 15, be provided with seal ring, packing ring, housing 15 fronts are provided with cover plate 18, cover plate 18 is fixed on housing 15 by screw 7, cover plate 18 is provided with nameplate groove 17, housing 15 one end are provided with suspension ring 1, the other end is provided with ball journal 12, ball journal 12 is fastened on housing 15 by gland 11, ball journal 12 is internally connected with guide rod 9 at housing 15, the guide rod 9 sheathed stage clips 10 in outside, guide rod 9 other ends are connected with switch 6 by screw 7.
Described nameplate groove 17 is fixed on cover plate 18 by rivet 16.
Between described gland 11 and housing 15, be bolted fixing.
Screw 7 between described guide rod 9 and switch 6 is provided with spring washer 14.
Between described cover plate 18 and housing 15, be provided with packing seal 19.
Described shell is to be assembled by intrinsic safety housing 15, in travel switch 6 is arranged on, travel switch 6 adopts silver contact, install on wiring board, wiring board is arranged in intrinsic safety housing 15, described intrinsic safety housing 15 is to adopt the casting integrated structure of HT250 material, housing 15 is by having the screw thread incoming line of water-proof function, seal ring, back-up ring, hold-down nut 5 is delivered to belt feeder main frame or other equipment by coal piling sensor actuating signal, this housing 15 is provided with mounting hole and erection column, the utility model is simple in structure, installation and repairing is convenient, when the coal piling of belt feeder, coal bunker is higher than normal position, the guide rod 9 that at this moment can promote coal piling moves, guide rod 9 moves and promotes travel switch 6 actions, thereby make its output switch 6 signals, after trouble shooting, it relies on retracing spring automatically to recover.In the middle of guide rod 9, by screw, meshes, can dismantle and lengthen guide rod 9, because the mounting hole of wiring board is designed to oblong, the position of therefore installing can parallel, and the angle of action can change.Adopt 1 L19B micro limit switch 6. that a coal piling sensor is connected, the coal piling that gets final product belt feeder protects this product structure simple, easy to use, and water proof and dust proof performance is good.
The utility model does not need power supply, and the load of maximum 250V5A can be provided, and when being subject to external force (the belt promotion of belt feeder etc.), exporting and often opens or normally closed contact, supplies with the equipment that connects and uses.
When the coal piling of belt feeder, coal bunker is higher than normal position, and the guide rod 9 that at this moment can promote coal piling moves, and guide rod 9 moves and promotes travel switch 6 actions, thereby makes its output switch 6 signals, and after trouble shooting, it relies on retracing spring automatically to recover.
During use, the guide rod of coal piling sensor 9 is connected to lengthening bar and lengthen, can realize dark coal bunker coal piling protection, product is simple and reliable, is simple and easy to meeting safety good.
More than show and described groundwork of the present utility model and principal character and advantage of the present utility model.The technical personnel of the industry should be understood; the utility model is not restricted to the described embodiments; that in above-described embodiment and specification sheets, describes just illustrates principle of the present utility model; do not departing under the prerequisite of the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.Claimed scope of the present utility model is defined by appending claims and equivalent thereof.
