Description
Technical field
The utility model is related to mire ventilation safety protection technology field, specifically a kind of explosion-proof door of coal miine vertical shaft
Automatic assistance for lifting and quick-locking device.
Background technology
Vertical ventilating shaft explosion-proof door is the critical facility of mire ventilation safety.Explosion proof door is also known as Explosion-proof cap, and mounting arrangements are going out
On wellhead platform face on the same axis of ventilating shaft.The effect of explosion proof door is mainly reflected in the following aspects：（1）, mine it is normal
During ventilation, air-tightness is kept, for isolating underground air-flow and surface air, prevents Air escape branch, ensures that ventilating system is normal；
（2）, when underground is Yi Dan occurring gas or during coal-dust explosion, explosion proof door（Lid）The gas shock ripple to be exploded is opened, and is caused distinguished and admirable
Short circuit, air blast are directly discharged to surface air, reduce the pressure of air-flow in mine, play the role of release, prevent mainly logical
Wind turbine damages due to air blast impacts；（3）, fire occurs or there are during toxic gas when underground intake, in order to
Prevent flame and toxic gas from entering exploiting field and endangering miner's life, it is necessary to carry out inverted ventilation fire extinguishing in time, this is just needed in time will be anti-
Quick-fried door（Lid）It compresses, inverted ventilation is enforced to underground using positive pressure mode；（4）, in chief ventilators accidental power failure or there is machine
When tool failure and other reasons shut down, explosion proof door can automatically open, and the certain ventilation quantity of mine is kept using natural ventilation pressure.Root
According to the 158th article of regulation of safety regulations in coal mine：6 monthly repairs of explosion proof door are once.Safety regulations in coal mine the 161st
Item provides：When chief ventilators shut down, it is necessary to open well head explosion proof door, utilize gravity-flow ventilation.
Explosion proof door is with negative pressure operating status, i.e. normally off during mine is normally divulged information.Wherein, the weight one of weight
As be slightly larger than door body weight, when mine blowing-out, door body can automatically open.But actual conditions, which lack, to be realized.It is common at present
Mine explosion door have the following problems：（1）, mine explosion door cannot be normally-open, main fan in mine is caused to stop transport
It can not be aerated during machine using mine natural ventilation pressure and normal service；（2）, mine explosion door can automatically turn on,
But in opening process there are door body deflection, casey, spend situations such as quick-break rope, and design Lift is not achieved, Ke Nengzao
It is damaged into explosion proof door, while during explosion proof door reset, need to manually move movement weight mass, can not started with again since casting pig weight is big
Part causes door body to reset difficult, and resetting time is long, seriously affects effect of natural ventilation, delays the available machine time.Therefore, it is some
Colliery is directly all compressed with the counterweight that reduces weight or with locking clamping block, and there are larger security hidden troubles.It also violates simultaneously
The 158th article of regulation of safety regulations in coal mine：6 monthly repairs of explosion proof door are once.Safety regulations in coal mine the 161st
Item provides：When chief ventilators shut down, it is necessary to open well head explosion proof door, utilize gravity-flow ventilation.
Method on explosion proof door automatic lifting with the means of variable mass it has been proposed that ensure uniform lifting problem, although energy
It solves the above problems, is proved through using, which needs increased affiliated facility more, such as becomes measuring tank, distribution water tank, becomes
Water-masuring box, water pump, pipeline, valve etc., not only cumbersome, mass flow discrepancy weighing apparatus distribution, the operating time is long, live in disorder, and adopts
Taking equipment Insulation, it is of high cost, it is big to promote difficulty.
Also there is locking in explosion proof door, before back lass, need to manually rotate 8 locking pressures on explosion proof door excircle
Block, when personnel prepare deficiency, weather influences, lock door body operation takes more.According to measuring and calculating：Personnel fully, behaviour
In the case of making skillfully, the explosion-proof door latch operating time up to 3 minutes or so, occupies the back lass time, so that sometimes 10
Inverted ventilation operation cannot be completed in minute.Explosion proof door is opened and the locking consuming time is more, may be come to mine lower band unexpected
Disaster.
It is time-consuming for the locking of 8 briquettings of explosion proof door, extend the back lass operating time, automatization level is low etc. asks
Topic, is improved, i.e., is locked using electric pushrod or with hydraulic push rod, achievees the purpose that auto lock, but the dress
It puts making and installation is complicated, appearance and size is big, unsightly.
Therefore how to realize that the automatic lifting of explosion proof door and quick locking are that technology present in currently available technology is asked
Topic.

Specific work process：After ventilation blower shuts down, first start hydraulic station 23, restart 17 raising of oil cylinder by
Button, oil cylinder 17 drive movable pulley 15 to move down, cause haulage cable 12 toward bottom offset, since 12 one end of haulage cable is consolidated
The weight much other ends for determining explosion proof door door body 6 fix catcher 18（Movable bearing support 18-2）Weight, there is stress and injustice
Weighing apparatus promotes the haulage cable 12 for being fixed on 18 one end of catcher to wriggle, it is necessary to balance-seeking again.The traction of haulage cable 12 is caught
The briquetting 18-4 for catching device 18 moves down, and is further driven to arresting hook 18-5 and moves down, until arresting hook 18-5 passes through activity
Bearing 18-2 proceeds to horizontal level, and wriggling displacement is LS1, movable pulley 15 displacement LX1, LS1=2LX1, while arresting hook 18-5
It has inserted in the guiding piece 21-1 empty slots such as traction separated structure 21.Briquetting 18-4, arresting hook 18-5, one 18-7 of spring, activity branch
Seat 18-2 etc. is whole to have become rigid body.When oil cylinder 17 drives movable pulley 15 to continue to move down, according to the equilibrium principle of power, both ends are led
Draw steel wire rope 12 and continue balance-seeking, the haulage cable 12 for being fixed on 18 one end of catcher is wriggled with rigid bodies such as movable bearing support 18-2
It is LS2 to continue to compress two 18-6 of spring and wriggled down to displacement, and arresting hook 18-5 is tangled with guiding piece 21-1, LS2=2LX2.When
Oil cylinder 17 drive movable pulley 15 continue to move down, mounted on movable bearing support 18-2 arresting hook 18-5 drive guiding piece 21-1 after
Continuous compression two 18-6 of spring moves down together, and at this moment guiding piece 21-1 drives separation steel wire rope 19 to pass through 7 22 He of leading block
Weight 1 is promoted to LS3 by leading block 8 10, and LS3=2LX3 realizes weight separation purpose.Movable bearing support 18-2 displacements LS2+
After LS3, two 18-6 of spring no longer compressive deformations, thus movable bearing support 18-2 and hold-down support 18-1 and basis form newly firm
Body, this end are not in the fixing end being subjected to displacement, which has been far longer than 6 mass of explosion proof door door body, when 17 band of oil cylinder
When dynamic movable pulley 15 continues to move down, because one end is fixed point, haulage cable 12 is by leading block 3 13 by explosion proof door
Door body 6 is promoted, and is promoted to after meeting ventilation distance LX4, and 17 piston of oil cylinder stops movement, and piston range ability is LS4=1/
2LX4 completes to promote work.Landing is opposite with the above process.
By specific embodiment above, the those skilled in the art can readily realize the utility model.But
It is it should be appreciated that the utility model is not limited to above-mentioned specific embodiment.It is described on the basis of disclosed embodiment
Those skilled in the art can be combined different technical characteristics, so as to fulfill different technical solutions.
It is the known technology of those skilled in the art in addition to the technical characteristic described in specification.
