Embodiment 2: as Figure 7-9, the present invention provides a kind of technical solution, a kind of grating identification it is large-inclination-angle coal bed from
Dynamic gear cash door, M1 is door motor underground three phase alternating current motor, M2 is 24V direct current drive coal wiper motor, LD1, LD2, LD3 equal
It is total disconnecting switch for total power light, QS, QF1 is M1 door motor breaker, QF2 is M2 rectifier power source breaker, FU1 is
M2 direct current overcurrent protection fuse, KM1 are door motor shutdown contactor, KM2 is door motor enabling contactor, FH1 is door motor mistake
Carrying protector, C3, which be on coal wiper ,-lower contactor, C are under coal wiper-goes up contactor, KA be grating signal receiving relay,
SQ1 is door-closing in-place limiter, SQ2 be open the door limiter, SQ3 in place be under coal wiper-upper limit device, SQ4 be coal wiper
Upper-lower retainer, KT be electric time-delay relay 10S, SB1 be door motor scram button, SB2 be coal wiper scram button,
SB3 is door motor shutdown hand push button, SB4 is door motor enabling hand push button, HL be control circuit have electricity instruction, LD4 be pass
Door running LED, LD5 are enabling running LED, LD6 is door-closing in-place indicator light and LD7 is to open the door to refer in place
Show lamp.
Pass through in electrically operated gate door opening state if there is flying cash, motor 2 makes electrically operated gate execute shutdown movement, and door completely closes
When, touching limit switch 1 forms shutdown state, and when touching limit switch 1, motor 1 obtains electric and its work is made to drive ball
Lead screw rotation, so that motion contact ball-screw upper limit switch 3, motor 1 power off ball screw from the bottom to top, shutdown state
Motor 1 reopens after delay, i.e., door opening process, door can touch limit switch 2, motor in full open position
2 power-off, when touching limit switch 2, motor 1 must be electrically activated, when ball screw 1504 has up to lower motion contact limit switch 4
Motor 1 powers off, and in door opening process, has winged cash by grating again, door executes shutdown movement.
This is electrically operated gate switch gate process, and scrapes coal brush motion process.
Initial position door is scraped in opening state, the normally closed opening of enabling travel switch SQ2, normally opened closure, coal wiper in bottom
The normally closed opening of coal device the lower travel switch SQ4, normally opened closure, when having object to pass through in grating, grating output relay is acted,
KA1 closure, KM1 obtain electric self-locking, and motor M1 starts shutdown movement, and when door-closing in-place, the normally closed point off switch gate of SQ1 stops, together
When SQ1 opened point be closed, KT obtains electric timing 10 seconds, and C4 obtains electric, and coal wiper moves from bottom to top, stops after touching SQ3, completes
Coal movement is once scraped, door is in shutdown position at this time, and after 10 seconds, it is dynamic to obtain the contact electric time delay relay KT upper for coal wiper
Make, KT closure, KM2 obtains electric and self-locking beginning door opening process, and when opening the door in place, SQ2 closure C3 is obtained electric, and coal wiper is from top to bottom
Movement, when touching lower bit switch SQ4, coal wiper stopping movement returning to original position, and door and coal wiper complete a homing action.
In door opening process, grating relay receives signal output action again, and KA2 is disconnected, and opens the door and stops, while repeating to close the door and start
Movement.
The working principle of the invention and process for using: in the large-inclination-angle coal bed automatic catch cash door identified using a kind of grating
In the process, when coal seam slides above working face 1, the light that can be issued to photophore 2 is blocked, at this time 3 nothing of light-receiving device
Method receives the light signal that photophore 2 is launched, and signal is passed to control cabinet 8 by light-receiving device 3, in photophore 2 and light-receiving device 3
When emitting and receiving light signal, by protecting tube 4, coal seam can be effectively prevented during landing to 2 He of photophore
Light-receiving device 3 causes to collide, and causes photophore 2 and light-receiving device 3 to damage, extends the service life of photophore 2 and light-receiving device 3, leads to
Anticollision foam-rubber cushion 5 is crossed, when protecting tube 4 can be effectively avoided being collided, between protecting tube 4 and photophore 2 and light-receiving device 3
There is extrusion and collision, causes to damage, further prevented photophore 2 and light-receiving device 3 to be damaged, light-receiving device 3 transmits signal
After control cabinet 8, control cabinet 8 controls the rotation of the second driving motor 1702, and the second driving motor 1702 passes through 1708 band of chain
Dynamic transmission shaft 1706 rotates, and drives the rotation of the second drive bevel gear 1709 by the rotation of transmission shaft 1706, by bearing 1705,
It can make transmission shaft 1706 in the course of rotation more smoothly, due to the first drive bevel gear 12 and the second transmission cone tooth
By engagement connection between wheel 1709,12 turns of the first drive bevel gear can be driven by the rotation of the second drive bevel gear 1709
It is dynamic, it drives main shaft 9 to rotate by the rotation of the first drive bevel gear 12, drives ball-screw 18 to rotate by the rotation of main shaft 9,
And then gear cash door 14 is driven to rotate, it is blocked by keeping off 14 pairs of winged cash of cash door, realizes automation control, do not need artificial
Gear cash door 14 is controlled, meanwhile, by the effect of fixed link 10, it can prevent main shaft 9 from shaking in the course of rotation
Dynamic phenomenon, when more dust is saved bit by bit on gear 14 surface of cash door, passes through control cabinet 8 so that the rotation of gear cash door 14 is more stable
The power supply for connecting the first driving motor 1502 drives threaded rod 1503 to rotate, passes through by the rotation of the first driving motor 1502
The rotation of threaded rod 1503 drives ball screw 1504 to rotate, and drives sliding panel 1505 keeping off by the rotation of ball screw 1504
14 side of cash door slidably reciprocates, and is carried out by the coal ash that 1507 pairs of scraper block gear 14 surfaces of cash door of 1505 side of sliding panel are saved bit by bit
It strikes off, ensure that the clean level on gear 14 surface of cash door, gear cash door 14 executes the operation acts of one bout, the first driving every time
Motor 1502 all can drive scraper block 1507 to be cleared up on the door, keep the cleaning of the shop front, also, gear 14 pairs of coal seams of cash door into
During row blocks, by dustcloth 1605, coal ash can be effectively prevented and entered inside sliding slot 1601, sliding slot 1601 is made
At blocking, sliding block 1506 is caused to occur Caton phenomenon in 1601 internal slide of sliding slot, also, when sliding block 1506 is in sliding slot 1601
When internal slide, sliding block 1506 will drive dustcloth 1605 in the outer Slideslip of sliding slot 1601, at this point, can be with by folding and unfolding roller 1603
It realizes the receipts to dustcloth 1605 and puts, it is dust-proof to ensure that dustcloth 1605 always carries out sliding slot 1601, also, work as scraper block
After the coal ash for keeping off 14 side of cash door is struck off and finished by 1507, can pass through the self-recovery ability of plane scroll spring 1604 will
Dustcloth 1605 is taken in inside storage box 1602, convenient and efficient.
Finally, it should be noted that being not intended to restrict the invention the foregoing is merely preferred embodiment of the invention, to the greatest extent
Present invention has been described in detail with reference to the aforementioned embodiments for pipe, for those skilled in the art, still can be with
It modifies the technical solutions described in the foregoing embodiments or equivalent replacement of some of the technical features.It is all
Within the spirit and principles in the present invention, any modification, equivalent replacement, improvement and so on should be included in guarantor of the invention
Within the scope of shield.
