Description
Technical field
The utility model relates to a kind of main shaft bottom coal piling monitoring for protection devices.
Background technique
General Coal Mine Design is that main shaft mentions coal, when main hoist is under human error or burst conditions, i.e., skip bucket cross dress,
Situations such as coal mouth spreads charcoal, skip bucket door fits badly is slipped, all shaft bottom coal piling can be caused excessive, tail ropes of elevator torsion support will be caused
It rises, draws bad main hoist pit gear facility, pulls and break the severe accident such as tail ropes of elevator.
Chinese invention patent disclosed on 04 04th, 2012 discloses a kind of main shaft hoist shaft bottom coal pile monitoring dress
Set, it be it is a kind of using material level gauge, coal bunker level relay, air velocity transducer is to coal mine main shaft hoist shaft bottom coal pile height, position
Coal hopper stopping state difference real-time monitoring is spread with shaft bottom, calculation processing is carried out by coal piling monitoring center, is alarmed and is controlled
System prevents coal mine main hoist under human error or burst conditions and the excessive caused promotion tail of the shaft bottom coal piling of appearance
Rope torsion is held up, and is drawn bad main hoist pit gear facility, is pulled the safety monitoring technology measure for breaking tail ropes of elevator.It is main
Three resampling of coal hopper stopping state is spread in well elevator shaft bottom coal piling height, position and shaft bottom, and report is implemented in redundant processing respectively
Alert and control.
But due to moist at main shaft leakage coal eye, wind is big, water drenching is big, Pulverized Coal mostly etc., bad environments, air velocity transducer passes through
Often it is out of order.
Utility model content
The technical problems to be solved in the utility model is how to overcome the drawbacks described above of the prior art, provides a kind of main shaft bottom
Coal piling monitoring for protection device.
In order to solve the above technical problems, this main shaft bottom coal piling monitoring for protection device includes sound-light alarm circuit and pedestal,
Be characterized in that: it further includes permanent magnet, magnetic induction normal open switch and lever bracket, and permanent magnet and magnetic induction normal open switch are oppositely arranged
On pedestal, it is equipped with one therebetween and hides magnetic sheet, the lever bracket includes horizontal axis, and horizontal axis both ends pass through two bearings respectively to revolve
It is fixed on pedestal with turning, horizontal axis middle section has been respectively fixedly connected preceding vertical pole and rear vertical pole, and it is normally opened that preceding vertical pole stretches to permanent magnet, magnetic induction
Between switch, rear vertical pole is directed toward obliquely downward, and before the screening magnetic sheet is secured on vertical pole, the rear vertical pole lower end is connected with a wind
Plate, magnetic induction normal open switch concatenate into the sound-light alarm circuit, and the aerofoil is arranged in tunnel below adapted leakage coal mouth and meets
At wind.
In the case where pit shaft is unobstructed, leakage coal mouth both ends wind is very big at main shaft bottom.But when main hoist is artificially losing
When the shaft bottom coal piling accidentally or under burst conditions occurred is excessive, the leakage coal mouth of lower part can be blocked, be leaked at coal mouth just not from well
The wind that cylinder gets off, the utility model make full use of this phenomenon.
It is designed in this way, when adapted leakage coal mouth is normal, the wind from main shaft is normally blown on aerofoil, before making under vertical pole
Pressure, screening magnetic sheet thereon are inserted between permanent magnet, magnetic induction normal open switch, and magnetic induction normal open switch incudes the magnetic less than permanent magnet
Property, in dress state is disconnected, sound-light alarm circuit is not triggered.
Conversely, aerofoil is affected by gravity pushing, and preceding vertical pole is tilted, and hides magnetic sheet when leakage coal mouth is blocked and do not have wind or small wind
It leaves between permanent magnet and magnetic induction normal open switch, magnetic induction normal open switch is triggered by permanent magnet and is closed, and triggers sound-light alarm
Circuit issues alarm, so that staff carries out inspection processing to equipment in time, prevents the generation of accident.
As optimization, the rear vertical pole is made of the two parts being hinged, and articulated shaft is the bolt that can be screwed.So
Design, the angle of adjustable aerofoil.
The utility model main shaft bottom coal piling monitoring for protection device has that structure is simple, is suitble to leakage coal mouth in high humidity, high dirt
Work nearby is suitable for major coal mine.
Detailed description of the invention
The utility model main shaft bottom coal piling monitoring for protection device is described further with reference to the accompanying drawing:
Fig. 1 is the schematic perspective view of this main shaft bottom coal piling monitoring for protection device.
In figure: 1 be pedestal, 2 be permanent magnet, 3 be magnetic induction normal open switch, 4 be hide magnetic sheet, 5 be horizontal axis, 6 be preceding vertical pole,
7 it is rear vertical pole, 8 be aerofoil, 9 be the bolt that can be screwed, 10 is aerofoil counterweight adjustment hole.
Specific embodiment
Embodiment one: as shown in Figure 1, this main shaft bottom coal piling monitoring for protection device include sound-light alarm circuit (in figure not
Show) and pedestal 1, it is characterised in that: it further includes permanent magnet 2, magnetic induction normal open switch 3 and lever bracket, permanent magnet 2 and magnetic strength
It answers normal open switch 3 to be oppositely arranged on the pedestal 1, is equipped with one therebetween and hides magnetic sheet 4, the lever bracket includes horizontal axis 5, horizontal axis 5
Both ends pass through two bearings respectively and are removably secured on pedestal 1, and preceding vertical pole 6 and rear vertical pole has been respectively fixedly connected in 5 middle section of horizontal axis
7, preceding vertical pole 6 stretches between permanent magnet 2, magnetic induction normal open switch 3, and rear vertical pole 7 is directed toward obliquely downward, and the screening magnetic sheet 4 is just fixed
On preceding vertical pole 6, rear 7 lower end of vertical pole is connected with an aerofoil 8, and magnetic induction normal open switch 3 is concatenated into the sound-light alarm circuit,
The place windward in tunnel below adapted leakage coal mouth is arranged in the aerofoil 8.
For vertical pole 7 by the bipartition being hinged, articulated shaft is the bolt 9 that can be screwed after described.On the aerofoil 8 also
Equipped with aerofoil counterweight adjustment hole 10.
