Specific embodiment
The utility model is described in further detail below in conjunction with the accompanying drawings：
With reference to shown in Fig. 1, the utility model is installed on two in doorframe (1) including doorframe (1), by linkwork (4)
A door leaf (2), each door leaf (2) are both provided with ventilating mechanisms (5) and blocking mechanism (3), and ventilating mechanisms (5) are installed on door leaf
(2) middle and upper part.
The air door uses the arrangement form of upper and lower longitudinal stress.Door leaf (2) structure is girder steel harden structure, can be absorbed impact
Ripple load, final load are transferred on both sides doorframe (1) and doorframe (1) wall.Door leaf (2) is welded into cross beam bone using shaped steel group
Frame, inside and outside steel plate weld therewith it is integral, to absorb impact load.Door leaf (2) effectively transfers load by locking head (32)
Give doorframe (1).
It since the air door size is big, is in turn mounted among air passage, can not transport as a whole, therefore make doorframe (1)
It is left and right each one section, assembled on platform after each section processes into two sections, the flatness on doorframe (1) surface is controlled with level meter,
It is fitted together with positioning pin and bolt after meeting the requirements, and is supported with interim I-steel and angle steel.Each section is dismantled during transport,
It transports to behind scene and is assembled into an entirety again, being welded at docking after adjustment, then stile is installed.
With reference to shown in Fig. 2 and Fig. 3, the blocking mechanism (3) of this includes the reducer of turbodrill mounted on door leaf (2) middle and lower part
(31), the guide rod (34) that is connected with the power output end of reducer of turbodrill (31) is connected by pivoted arm (35) with guide rod (34)
Connecting rod (33), the tapered end (32) being connected with connecting rod (33), pivoted arm (35) be V-type arm, two ends respectively with connecting rod (33) and guide rod
(34) it is hinged, by reducer of turbodrill (31) tapered end (32) is driven to be moved in vertical direction.Guide rod (34) lateral arrangement, connecting rod
(33) longitudinally disposed, the inside of pivoted arm (35) is towards connecting rod (33) and the extending line intersection point of guide rod (34).
Big door leaf (2) is designed as longitudinal stress, the predominantly upper and lower arrangement form of tapered end (32) structure.Reducer of turbodrill
(31) set there are two the power intake for being connected with handwheel, two handwheels are respectively arranged in the front and back of door leaf (2).Hand
Wheel is located at centre, unlocks and shuts by reducer of turbodrill (31) and connecting rod (33).This blocking mechanism (3) is used to provide extruding
The power of sealing joint strip.To make tapered end (32) stress and door leaf (2) uniform force reasonable, left and right door leaf (2) respectively arranges 4 tapered ends
(32), 8 tapered ends (32) are had altogether, this 8 tapered ends (32) are located at door leaf (2) lower edges.All tapered ends (32) are being locked simultaneously
Adjust pad is equipped between seat and door leaf (2).
Blocking mechanism (3) has following advantage using this mechanism form：
1) locking is placed in door leaf (2) outer surface, convenient for care and maintenance；
2) light and fast is closed in locking linkage, and a handwheel can drive multiple tapered ends (32) on a door leaf (2) synchronous
Action；
3) when door leaf (2) bears the Dynamic load of nuclear blast effect of positive direction, door leaf (2) stress is than more uniform；
4) distance of locking considers the arrangement of aeration structure, ensures with ventilation device not interfere.
The operation principle of blocking mechanism (3)：Handwheel is rotated, horizontal guide rod (34) is driven by reducer of turbodrill (31), it is horizontal
Vertical link (33) is driven by pivoted arm (35) again to guide rod (34), so drive tapered end (32) move up and down to implement to unlock and
It shuts.
With reference to shown in Fig. 4, linkwork (4) includes being fixed on the upper free bearing (42) on doorframe (1) top, is fixed on doorframe
(1) the lower free bearing (44) of lower part, be connected between free bearing (42) and lower free bearing (44) and rotatable vertical shaft (41), by door leaf
(2) door leaf hinge (46) to link together with vertical shaft (41)；Cylinder rolling is provided between vertical shaft (41) and upper free bearing (42)
Bearing (43), vertical shaft (41) are supported on by cone rolling (45) in lower free bearing (44).
For the air door of this large scale, big quality, whether the switch of the flexibility of linkwork (4) on the door is light
It is most important, while linkwork (4) will bear to topple caused by door leaf (2) gravity when door leaf (2) is in opening.It should
Linkwork (4) is full rolling structure, employs rolling bearing, and the frictional resistance that the upper and lower end of vertical shaft (41) is subject to is rolling
Friction, therefore translate laborsaving, door leaf (2) and hinge page with going slick when light, switch gate is laborsaving, door leaf (2) compresses adhesive tape
The features such as easy to connect.
With reference to shown in Fig. 5 and Fig. 6, ventilating mechanisms (5) include the formula valve (51) that dangles being mounted on door leaf (2), dangle
The rear portion of formula valve (51) is provided with dust filtering case (53) and hand-electric airtight valve (52), and dust filtering case (53) filters for entering the wind.It should
The formula that dangles valve (51) selects anti-explosive valve, with reference to applying wide HK600 valve in engineering.Each door leaf (2) is opened
If there are one ventilation hole, and from top to bottom there are three the formula valve (51) that dangles, three outstanding for overlapping installation successively in this ventilation hole
The rear portion connection of pendulum-type valve (51), and there are one dust filtering case (53) and two hand-electric airtight valves (52) for setting.Two door leafs
(2) six formula valve (51) that dangle are had altogether, total draught area is 0.56m2, ventilation quantity 16000m3/h.Dust filtering case (53) are set
Meter can be to being filtered, and hand-electric airtight valve (52) behind the door is double link sealed valve, model DMF50.Mode letter
It is single, it is easy to operate.Two fan doors set altogether 4, draught area 0.78m2, meet air-conditioning requirement.Flashlight movable valve can lead to
Cross the closing of manual and electronic two ways, Open valve.
The above is only the preferred embodiments of the present utility model only, is not intended to limit the utility model, all in this practicality
All any modification, equivalent and improvement made within new spirit and principle etc., should be included in the guarantor of the utility model
In the range of shield.
