Abstract
The invention discloses a magnetic control deviation sensor of a mine belt conveyor. An insulating plate is arranged in an outer shell, the insulating plate is provided with a magnetic proximity switch and a wiring card in a spaced mode, a wire of the magnetic proximity switch is connected with the wiring card, a guide rod penetrates through one side wall of the outer shell, the inner end face of the guide rod is provided with a permanent magnet, the permanent magnet corresponds to the magnetic proximity switch, the outer end of the guide rod is connected with one end of a universal movable rod, the outer shell is provided with two fixing bases, center holes in the fixing bases are provided with data lines, the inner ends of the data lines are connected with the wiring card, and the outer ends of the data lines are connected with a controller. The magnetic proximity switch serves as a protective motion output unit and is high in sensitivity and convenient to operate, a guide rod drives the permanent magnet to move when a belt deviates, and a normally-closed contact of the magnetic proximity switch is switched off under the action of magnetism so as to achieve a protective function.
Description
technical field:
The present invention relates to a kind of coal mine sensors, particularly relate to a kind of coal mine rubber belt conveyer magnetic control misalignment sensor.
background technology:
Misalignment sensor is travelling apron integrated protection---the important component part of " five protections greatly "; misalignment sensor is applicable to adhesive tape both sides, colliery; once rubber belt from deviating; adhesive tape just touches Universal active bar makes its action; by the outside output switch amount of sensor, to control convenience, realize rubber belt from deviating power-off protection function.On travelling apron, use at present more GEJ30 type misalignment sensor be a kind of based on mechanical trip switch the sensor as switching value output unit.Misalignment sensor is selected LX19K-B travel switch, has a pair of normal battle and a pair of normally closed point.When adhesive tape generation sideslip or while doing sideslip protection test, the action of Universal active bar promotes guide rod crush stroke switch, until normally closed contact disconnects, reaches protective effect.Easily there is oxidative phenomena in the type sideslip protection travel switch contact; and sensor mechanism due to test and protection need frequent movement; because of the feature of travel switch inner structure own; its mechanism's anti-fatigue ability is poor; contact contact is not firm, causes sensor fault rate high, and replacement frequency is higher; cause belt machine heavy load shutdown, belt feeder cannot start, protect the faults such as inoperative, have serious potential safety hazard.
summary of the invention:
Technical matters to be solved by this invention is: overcome the deficiencies in the prior art, provide a kind of reasonable in design, easy to use, stable and reliable for performance, safety is good and the coal mine rubber belt conveyer magnetic control misalignment sensor of long service life.
Technical scheme of the present invention is: a kind of coal mine rubber belt conveyer magnetic control misalignment sensor, contain shell and cover plate, the two is bolted, in described shell, insulcrete is installed, on described insulcrete, interval is provided with magnetic approach switch and wiring card respectively, the wire of described magnetic approach switch is connected with described wiring card, a lateral body wall that runs through described shell is provided with guide rod, on the inner end surface of described guide rod, be provided with permanent magnet, described permanent magnet is corresponding with described magnetic approach switch, the outer end of described guide rod is connected with one end of Universal active bar, on described shell, be provided with two permanent seats, the centre hole of described permanent seat is communicated with described shell inner cavity, in described centre hole, be provided with data line, the inner end of described data line is connected with described wiring card, the outer end of described data line is connected with controller.
The centre hole outer end of described permanent seat is provided with bolt of rear end plate, described bolt of rear end plate hollow and be provided with sealing ring pad.Described magnetic approach switch is arranged on described insulcrete by Ω shape fixed mount and bolt.The inner end surface of described permanent magnet and described guide rod is fixed, is welded and fixed, is adhesively fixed or inlays fixing.Prismatic, the cylindrical or truncated cone-shaped of being shaped as of described permanent magnet; The outer end of described guide rod is connected with one end rotary type of Universal active bar.
The invention has the beneficial effects as follows:
1, the present invention meets dynamo-electric intact and explosion-proof criteria, stable and reliable for performance, not only extended its service life, saved again use cost, and eliminated potential safety hazard, reduce the electromechanics impact bringing because of travel switch fault, further ensured the safe and highly efficient operation of equipment, can bring 1,000,000 yuan of economic benefits.
2, fixed mount of the present invention is for fixed magnetic approach switch, and its " Ω " shape structure is convenient to prevent that magnetic approach switch from moving or being shifted, by being bolted on insulcrete and shell, once fix, just can the locked switch position.
3, the present invention is using magnetic approach switch as protection action output unit, highly sensitive, controls conveniently, and when adhesive tape generation sideslip, guide rod drives permanent magnet motion, and magnetic approach switch normally closed contact under magnetic action disconnects, and reaches defencive function.
4, permanent magnet of the present invention is arranged on guide rod end face, by its magnetic and the reliable adhesive of guide rod end face, or by the two welding, bonding or by screw boring connection, fixed, difficult drop-off, good stability; In addition, that permanent magnet shape is generally is square, cylindrical, circular platform type, icepro column type, and flexible and changeable, implementation result is good.
5, result of use of the present invention is good, and cost is lower, and it is applied widely, is easy to promotion and implementation, has good economic benefit.
accompanying drawing explanation:
Fig. 1 is the structural representation of coal mine rubber belt conveyer magnetic control misalignment sensor.
the specific embodiment:
Embodiment: referring to Fig. 1, in figure, 1-bolt of rear end plate, 2-permanent seat, 3-wiring card, 4-wire, 5-magnetic approach switch, 6-fixed mount, 7-permanent magnet, 8-guide rod, 9-Universal active bar, 10-insulcrete, 11-shell, 12-cover plate.
Coal mine rubber belt conveyer magnetic control misalignment sensor contains shell 11 and cover plate 12, the two is bolted, wherein: insulcrete 10 is installed in shell 11, on insulcrete 10, interval is provided with magnetic approach switch 5 and wiring card 3 respectively, the wire 4 of magnetic approach switch 5 is connected with wiring card 3, a lateral body wall that runs through shell 11 is provided with guide rod 8, on the inner end surface of guide rod 8, be provided with permanent magnet 7, permanent magnet 7 is corresponding with magnetic approach switch 5, the outer end of guide rod 8 is connected with one end of Universal active bar 9, on shell 11, be provided with two permanent seats 2, the centre hole of permanent seat 2 is communicated with shell 11 inner chambers, in centre hole, be provided with data line (not shown in FIG.), the inner end of data line is connected with wiring card 3, the outer end of data line is connected with controller.
