Description
Technical field:
The present invention relates to a kind of coal mine sensors, particularly relate to a kind of Magnetic control deviation sensor of mine belt conveyor.
Background technology:
Misalignment sensor is the important component part of rubber conveyer integrated protection " 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 sensor outside output switch amount to control equipment, it is achieved rubber belt from deviating power-off protection function.Using more GEJ30 type misalignment sensor on rubber conveyer at present is a kind of mechanically-based travel switch sensor as output switch parameter unit.Misalignment sensor selects LX19K-B travel switch, has a pair normally opened point and a pair normally closed point.When adhesive tape generation sideslip or when doing sideslip protection test, Universal active bar action 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 internal structure own; its mechanism's anti-fatigue ability is poor; contact is the most firm, causes sensor fault rate high, and replacement frequency is higher; cause belt machine heavy load to be shut down, belt feeder cannot start, protect the faults such as inoperative, there is serious potential safety hazard.
Summary of the invention:
The technical problem to be solved is: overcome the deficiencies in the prior art, it is provided that a kind of reasonable in design, easy to use, stable and reliable for performance, safety is good and the Magnetic control deviation sensor of mine belt conveyor of length in service life.
The technical scheme is that a kind of Magnetic control deviation sensor of mine belt conveyor, containing shell and cover plate, the two is bolted, in described shell, insulation board is installed, it is respectively separated on described insulation board and magnetic approach switch and wiring card are installed, the wire of described magnetic approach switch is connected with described wiring card, the side body wall running through described shell is provided with guide rod, it is provided with permanent magnet on the inner face of described guide rod, 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, two fixing seats it are provided with on described shell, the centre bore of described fixing seat connects with described shell inner cavity, described centre bore is provided with data wire, the inner end of described data wire is connected with described wiring card, the outer end of described data wire is connected with controller.
The centre bore outer end of described fixing seat is provided with fixing bolt, described fixing bolt hollow and be provided with sealing ring pad.Described magnetic approach switch is arranged on described insulation board by Ω shape fixed mount and bolt.Described permanent magnet is fixed, is welded and fixed, is adhesively fixed or inlays fixing with the inner face of described guide rod.Being shaped as of described permanent magnet be prismatic, cylindrical or truncated cone-shaped；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 extend its service life, save again use cost, and eliminate potential safety hazard, decrease the dynamo-electric impact brought because of travel switch fault, ensured the safe and highly efficient operation of equipment further, economic benefit million yuan can be brought.
2, fixed mount of the present invention is used for fixed magnetic proximity switch, and its " Ω " shape structure is easy to prevent magnetic approach switch from moving or shift, and by being bolted on insulation board and shell, once fixes, it becomes possible to the locked position of the switch.
3, the present invention is using magnetic approach switch as protection act 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 magneticaction 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 the two is welded, bonding or connect by screw boring, fixed, difficult drop-off, good stability；It addition, permanent magnet shape is the most square, cylindrical, circular platform type, icepro column type, flexible and changeable, implementation result is good.
5, using effect of the present invention is good, and cost is relatively low, and it is applied widely, it is easy to promotion and implementation, has good economic benefit.
Accompanying drawing illustrates:
Fig. 1 is the structural representation of Magnetic control deviation sensor of mine belt conveyor.
Detailed description of the invention:
Embodiment: see Fig. 1, in figure, 1-fixes bolt, and 2-fixes seat, 3-wiring card, 4-wire, 5-magnetic approach switch, 6-fixed mount, 7-permanent magnet, 8-guide rod, 9-Universal active bar, 10-insulation board, 11-shell, 12-cover plate.
Magnetic control deviation sensor of mine belt conveyor contains shell 11 and cover plate 12, the two is bolted, wherein: insulation board 10 is installed in shell 11, it is respectively separated on insulation board 10 and magnetic approach switch 5 and wiring card 3 are installed, the wire 4 of magnetic approach switch 5 is connected with wiring card 3, the side body wall running through shell 11 is provided with guide rod 8, permanent magnet 7 it is provided with on the inner face of guide rod 8, 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, two fixing seats 2 it are provided with on shell 11, the centre bore of fixing seat 2 and shell 11 inner space, centre bore is provided with data wire (being not drawn in figure), the inner end of data wire is connected with wiring card 3, the outer end of data wire is connected with controller.
