Abstract
The utility model discloses a coal mine belt conveyer magnetic control deviation sensor. An outer shell of the sensor is internally equipped with an insulating plate. A magnetic proximity switch and a wiring card are mounted on the insulating plate at an interval. Lead wires of the magnetic proximity switch are connected with the wiring card. A guide rod is arranged in a manner of penetrating 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 moving rod. Two fixing seats are arranged on the outer shell. A center hole of each fixing seat is internally provided with a data line, and the inner end of the data line is connected with the wiring card while the outer end of the data line is connected with a controller. According to the utility model, the magnetic proximity switch is used as a protection motion output unit so that the magnetic control deviation sensor is high in sensitivity and convenient to operate; and when a belt deviates, the guide rod drives the permanent magnet to move and the normally-closed contact of the magnetic proximity switch is disconnected under the magnetic effect, thereby achieving the protection function.
Description
technical field:
The utility model relates to a kind of coal mine sensors, particularly relates 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; to control convenience, realize rubber belt from deviating power-off protection function by the outside output switch amount of sensor.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.

The technical solution of the utility model 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 beneficial effects of the utility model are:
1, the utility model meets dynamo-electric intact and explosion-proof criteria, stable and reliable for performance, not only extend its service life, save again use cost, and eliminate 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, the utility model fixed mount 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 utility model is using magnetic approach switch as protection action output unit, and highly sensitive, manipulation is convenient, 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, the utility model permanent magnet 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, the utility model result of use 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.
