Abstract
The utility model discloses an intrinsically safe deviation sensor for a coal mine, and relates to a sensor. The sensor comprises a base, a mechanical device arranged in the base and an upper cover arranged on the base, wherein the mechanical device comprises two travel switches fixed in the base; through holes are formed in the base opposite to the travel switches; two movable sheets are arranged in the through holes and contacted with the travel switches opposite to the movable sheets; and a rotatable probe is arranged outside a shell and contacted with one movable sheet. The sensor has the advantages that internal micro switches are touched through mechanical transmission of the probe, normally open contacts of the travel switches connected to a control system are changed into normally closed contacts, and a signal is sent to the control system, so that the aim of control is fulfilled; and the sensor has a simple structure, is easy to process and convenient to install and can be used in severe environment for a long time, and a visual and reliable means is provided for the safety production, scheduling, decision-making and directing of the coal mine.
Description
Technical field
The utility model relates to a kind of sensor; Specifically be that the intrinsic safety type misalignment sensor is used in a kind of colliery; Be not only applicable to use in the industry floor conveyors such as coal, metallurgy, chemical industry, building materials, traffic, electric power, grain, be suitable for having under the coal mine environment of gas, coal dust explosion hazard yet; Be mainly used in the detection of travelling apron sideslip, prevent owing to faults such as rubber belt from deviating cause that material overflows.
Background technology
Sensor is that indispensable sensitive member is controlled in the conveyer automation.At present, it is of a great variety that China's downhole safety is produced the monitoring sensor, and mostly the monitoring and controlling system of use is what developed the nineties in the past; Volume is big, and weight is big, complicated in mechanical structure; Inconvenient during use, maloperation appears easily, can not satisfy the requirement of keeping the safety in production on the ore deposit.
Summary of the invention
To the deficiency that prior art exists, the utility model provides a kind of mine intrinsic safety type misalignment sensor, and volume is little, and is in light weight, and physical construction is simple, and is easy to use, safe and reliable; It not only can be used in general place, and can be used in the place of the inferior specific (special) requirements of coal mine.
The utility model is realized with following technical scheme: a kind of mine intrinsic safety type misalignment sensor comprises base, is installed in the mechanical device in the housing and is installed in the loam cake on the base; Described mechanical device comprises 2 travel switches that are fixed in the base, and has through hole on the cooresponding base of the switch on the travel switch, and two movable plates are installed in the through hole, and movable plate contacts with switch on its cooresponding travel switch; Housing has a rotary feeler lever outward, and feeler lever contacts with one of them movable plate.
The beneficial effect of the utility model is:
1, touches the in-to-in travel switch through the mechanical drive of feeler lever, make often the opening of travel switch that is connected in the control system become normally closed point, give signal of control system, thereby reach the purpose that needs control, solve the safety guard-safeguard of all kinds of conveyers.
2, contact capacity big, be active in one's movements, reliably.
3, little, in light weight, explosion-proof, the antidetonation of compact conformation, volume, protection against the tide are suitable for using under the coal mine, have good market outlook; It is simple in structure, is prone to processing, and is easy for installation, can be in the medium-term and long-term use of rugged environment, for Safety of Coal Mine Production, scheduling and decision-making commander provide directly perceived, failure-free means.
Description of drawings
Below in conjunction with accompanying drawing the utility model is described further.
Fig. 1 is the utility model external structure scheme drawing;
Fig. 2 is this utility model inner structure scheme drawing;
Fig. 3 is the A-A cutaway view of Fig. 1.
Among the figure: 1, base, 2, travel switch, 3, movable plate, 4, feeler lever, 41, the feeler lever axle, 42, pull bar, 43, block, 5, loam cake.
The specific embodiment
As shown in Figure 1, mine intrinsic safety type misalignment sensor has a base 1, is installed in the mechanical device in the housing and is installed in the loam cake 5 on the base 1; Described mechanical device comprises 2 travel switches 2 that are fixed in the base 1, and has through hole on the cooresponding base of the switch on the travel switch 2, and two movable plates 3 are installed in the through hole, and movable plate 3 contacts with switch on its cooresponding travel switch 2; Housing has one can rotate feeler lever 4 outward, and feeler lever 4 contacts with one of them movable plate.
In the present embodiment, feeler lever 4 has a rotating feeler lever axle 41 and the pull bar 42 that is installed in feeler lever axle 41; One block 43 is installed on the feeler lever axle 41, and block 43 contacts with movable plate 3.Base 1 is fixed on the travelling apron support, and feeler lever 4 is in a side of belt.In order to increase area of contact, block 43 is a rectangle.
Base 1 constitutes the seal casinghousing that meets the coal mine downhole safety standard with loam cake 5, has 2 mouths on the base.One of them mouthful is the delivery port of signal, and making a mouth is reserved opening, is used for expansion and uses.Under the control of physical construction, realize the transmission of data.
Wherein: base 1, adopt Q235 material microdiecast housing; Shell protection grade height, good airproof performance, waterproof and dustproof;
Travel switch 2 when being touched, sends signal;
Movable plate 3 through the extruding of feeler lever 4, forces wherein that a movable plate touches cooresponding one group of travel switch, makes it to export one group of on-off signal; Feeler lever 4 then forces another movable plate to touch cooresponding one group of travel switch when continuing to tilt, and makes it to export another group on-off signal;
Feeler lever 4 is when rubber belt from deviating, and adhesive tape is run into the feeler lever of sideslip switch and driven the rotation of feeler lever axle, when feeler lever deflects into certain angle, stirs the travel switch in the sideslip switch, sends offset signals; Loam cake 5 covers its base with loam cake, sealing.
Working process: mine intrinsic safety type misalignment sensor is fixed on the travelling apron support; Feeler lever is fixed on belt one side; When operating adhesive tape generation deviation phenomenon, tape edge drives the feeler lever rotation and extruding makes it, if the feeler lever angle of inclination is during greater than the one-level operating angle; Force one of them movable plate to touch cooresponding one group of travel switch, make it to export one group of on-off signal; Then force another movable plate to touch cooresponding one group of travel switch when continuing to tilt greater than the two-step action angle, make it to export another group on-off signal like feeler lever; Two groups of on-off signals can be used for alarming or shutting down, thereby reach the purpose that needs control respectively to signal of control system, and after conveyer resetted and normally moves, feeler lever automatically reset.
