Embodiment person of ordinary skill in the field understood.
As depicted in figs. 1 and 2, the invention provides a kind of fast-open type underground flue insertion plate door, including two are vertically arranged
Doorframe 1, two 1 tops of the doorframe are horizontal a beam 2, and door-plate 3 is provided between two doorframes 1, and the door-plate 3 can
Move up and down along the doorframe 1, reducing motor 4, the output shaft of the reducing motor 4 are installed at right-hand member on the door beam 2
It is provided with wire spool 5；The middle part of the door beam 2 is provided with door-plate fixed pulley 6, and the middle part of the door beam 2 is provided with oil cylinder 7, the oil
The piston rod of cylinder 7 is arranged straight down, and the housing of the oil cylinder 7 is fixedly installed on a beam 2；In the upper surface of the door-plate 3
Place, the lower section of the corresponding door-plate fixed pulley 6 are provided with door-plate movable pulley 8；Pulley is provided with the left side of two doorframes 1 solid
Determine platform 9, on the pulley fixed station 9, be provided with hand basket pulley 10 and counterweight pulley 11.
The underground flue insertion plate door also includes hand basket 12, balancing weight 13, hand basket hanger rope 14 and counterweight hanger rope 15；It is described to carry
Basket 12 is arranged on the lower section of the pulley fixed station 9, and the balancing weight 13 is placed in the hand basket 12；The hand basket hanger rope 14
One end be fixedly connected on the hand basket 12, and the wheel wall of pile warp hand basket pulley 10, the other end is around being located at the outer of wire spool 5
Zhou Shang；One end of the counterweight hanger rope 15 is fixedly connected on the balancing weight 13, and the wheel of pile warp counterweight pulley 11 successively
Wall, the wheel wall of door-plate fixed pulley 6 and the wheel wall of door-plate movable pulley 8, the other end are fixedly connected on the piston rod top of the oil cylinder 7
End.
When reducing motor 4 is closed, as action of gravity, hand basket 12 fall in lowest point, the piston rod of oil cylinder 7 is contracted to liquid
In the housing of cylinder pressure, balancing weight 13 is moved downward pulls counterweight hanger rope 15, and door-plate 3 is lifted and causes flue by counterweight hanger rope 15 upwards
Open, when quick closedown flue is needed, reducing motor 4 is opened, and wire spool 5 is rotated, and curls up hand basket hanger rope 14, hand basket hanger rope 14
Hand basket 12 is pulled up, the balancing weight 13 in hand basket 12 also rises therewith, the pulling force in counterweight hanger rope 15 reduces, door-plate 3 exists
Move down in the presence of gravity, meanwhile, the piston rod of oil cylinder 7 is extended downwardly from, and door-plate movable pulley 8 is common counterweight hanger rope 15
The lower sharp downward movement of effect, and 3 sharp downward movement of door-plate is driven, until door-plate 3 drops down onto lowest point and cuts out flue.
On the door beam 2, it is provided between the door-plate fixed pulley 6 and the counterweight pulley 11 and can prevents to match somebody with somebody
The locking device 16 of the motion of weight hanger rope 15, when hand basket 12 is in the presence of hand basket hanger rope 14, after being moved upward to relevant position, lock
Tight device 16 works, and avoids counterweight hanger rope 15 from moving the locking of counterweight hanger rope 15.After counterweight hanger rope 15 is locked, door-plate 3 stops
Only move, now reducing motor 4 can shut down closing, and hand basket 12 can fall to falling after rise to lowest order under gravity
Put place.
After opening when 16 unexpected power-off failure of locking device or by control, locking device 16 will be unable to limit counterweight hanger rope
15 motions, under gravity, balancing weight 13 understands free-falling into hand basket 12, while balancing weight 13 can pull downward on counterweight
Door-plate 3 is lifted by hanger rope 15 upwards, and when counterweight hanger rope 15 lifts door-plate 3 upwards, and the piston rod of oil cylinder 7 is retracted oil cylinder upwards
In 7 housing, under the piston rod collective effect of counterweight hanger rope 15 and oil cylinder 7, door-plate 3 quickly can be moved up, so that flue
It is rapidly opened.
The lower section of the pulley fixed station 9 is provided with spring 17；The lower end of the spring 17 is fixedly installed, the spring
17 upper end is horizontally disposed buffer board 18, and the hand basket 12 is placed on the buffer board 18.As oil cylinder 7 and counterweight are hung
15 collective effect of cable, door-plate 3 promptly can be moved up and down, and now balancing weight 13 also quickly can be fallen back in hand basket 12, due to matching somebody with somebody
13 falling speed of pouring weight can be impacted when falling to bottom than very fast, and hand basket 12 is placed on buffer board 18, buffer board 18
Lower section arranges spring 17, and balancing weight 13 is impacted when falling into the hand basket 12 of bottom downwards, and buffer board 18 is moved downward, and spring 17 is pressed
Contracting terminates until impacting, to realize buffered.Avoid balancing weight 13 to hurtle down impact, parts thereof is caused to damage
It is bad.
On the track that the balancing weight 13 is moved up and down, the first limit switch 19 is provided with nearly upper extreme position, closely
The second limit switch 20 is provided with lower limit position.When reducing motor 4 is opened, hand basket 12 is moved upwards, while balancing weight 13
Also will move upwards, door-plate 3 is moved downward, when balancing weight 13 is touched the first limit switch 19, door-plate 3 moves to lowest order
Put, flue is closed, meanwhile, locking device 16 is locked, 15 stop motion of counterweight hanger rope, and door-plate 3 is also by stop motion, reducing motor
4 reversely rotate, and the pulling force in hand basket hanger rope 14 reduces, and drops down onto lowest point under hand basket 12, the hand basket when hand basket 12 reaches lowest point
12 touch the second limit switch 20, and reducing motor 4 is closed.
The locking device 16 is magnetic locking device or hydraulic cylinder mechanical locking device, and magnetic locking device is general
It is suitable for and the occasion of load underload, installs simple, small volume and controls simple and convenient.And hydraulic cylinder mechanical lock dress
Put the occasion for applying in general to big load, coupling mechanism force is larger and reliable lock.
Several rollers 21 are provided with the opposite side of two doorframes 1, several described rollers 21 are oppositely arranged
And it is vertically arranged；Equal and roller 21 described in both sides the wheel wall of the left and right sidewall of the door-plate 3 is fitted.Two side wheel 21 or so is pressed from both sides
Door-plate 3 is handled, door-plate 3 is moved up and down along the roller 21 of both sides, during the moving up and down of door-plate 3, the roller 21 of both sides
End of door plate 3 serves guiding and spacing effect, it is ensured that door-plate 3 vertically up and down, while will not also produce beat and rock waiting now
As, it is therefore prevented that door-plate 3 colliding with and contact friction etc. to doorframe 1, while also ensureing that counterweight hanger rope 15 lifts the mistake of door-plate 3 upwards
Journey middle door-plate 3 stably can be moved.
The lower section of the pulley fixed station 9 is provided with melt pit 22, the spring 17 and the buffer board 18 are arranged on ground
The bottom in hole 22, melt pit 22 increase the distance between 12 its lowest position of pulley fixed station 9 and hand basket so that in underground flue
The larger unlatching distance of door-plate 3 can be met in the case of insertion plate door single unit system small volume.
