Description
Technical field
The utility model relates to a kind of pneumatic balance air door with no pressure, the especially a kind of balance air door pneumatic with no pressure that can automatically control being applicable in mine ventilation system.
Background technology
In mine ventilation system, air door is one of important ventilation equipment, and its effect is to pass through pedestrian or vehicle, can block again distinguished and admirable.
Be no matter the disaster relief door in emergency rescue system or need frequent by the air door of people or vehicle, all need one can manual operation also can automatic shutter, again can Long-distance Control, and open and close convenient stable, opening force is little, fireproof performance is good balance air door.And existing air door realize stable poor, the air door of the device of incorgruous synchronous opening/closing close too fast, easily hinder pedestrian and damage air door, and can not unlocking be opened by twice air door simultaneously while needing twice air door to open in emergency rescue system simultaneously.
Utility model content
The purpose of this utility model is the weak point overcoming in prior art, provide a kind of simple in structure, working stability, can the incorgruous synchronous opening/closing of Long-distance Control the balance air door pneumatic with no pressure that can automatically control.
For achieving the above object, the balance air door pneumatic with no pressure that can automatically control of the present utility model, comprise air door, be located at respectively the transmission mechanism on relative two doorframes, between two described doorframes, be provided with a locking case, in locking case, be provided with the weight that can replace the quality such as lifting or simultaneously lifting two, two weights are connected with transmission mechanism through wire rope respectively, between two described weights, be provided with the locking inefficacy actuating cylinder being fixed on locking case, the push rod of locking inefficacy actuating cylinder is provided with the Breech block that two weights replace locking that limits triangular in shape, between Breech block and locking chamber interior wall, be provided with and recover locking limit spring,
Described transmission mechanism comprises and is located at a drive at body top, chain, drive link, actuating cylinder, power cylinder joint element for bar, bounce cylinder, cushion dashpot joint element for bar; On the door-hinge of door both sides, body top, be respectively equipped with a drive, on two drives, coiling has chain respectively, chain two ends are connected with respectively drive link, one side of door body is provided with actuating cylinder, drive link is connected with the output shaft of actuating cylinder by power cylinder joint element for bar, the opposite side of door body is provided with the cushion dashpot joint element for bar being connected with this side drive, and cushion dashpot joint element for bar is connected with the output shaft of bounce cylinder.
Between the output shaft of described actuating cylinder and drive, be provided with door and reach a baffle plate.
Beneficial effect, owing to having adopted such scheme, this balance air door by doorframe, two door leafs, chain bar transmission mechanism, actuating cylinder, door reach a baffle plate, the bounce cylinder of closing the door forms.The door-hinge of two door leafs is by being connected and realizing the incorgruous unlatching of synchronizeing with chain bar balanced controls, when the emergency management and rescue of needs Long-distance Control, when pedestrian or vehicle pass through, actuating cylinder acts on drive link by power cylinder joint element for bar, drive link band movable sprocket is realized the incorgruous synchronous unlatching of two pectinid doors, and when actuating cylinder reaches door and reaches baffle plate, air door is opened completely.Counter weight is connected with linkage by wire rope, self gravitation by weight is closed air door automatically, when two door leafs cut out automatically, bounce cylinder acts on drive link and actuating cylinder rightabout, can too fastly not cause hindering pedestrian and damage air door when two fan doors are closed.When needs two pectinid doors are opened simultaneously, locking inefficacy actuating cylinder action Breech block is pushed out, and now locking was lost efficacy, and a control system twice air door of can issuing an order is opened simultaneously.Can be used for emergency rescue system or mine air door can the incorgruous synchronous opening/closing of Long-distance Control the balance air door pneumatic with no pressure that can automatically control.
Advantage: non-pressure damper adopts the incorgruous synchronous opening/closing of pressure balance principle air door, uses chain bar balanced controls that the pressure acting on air door is converted into a kind of internal force by chain bar balanced controls and is balanced while having guaranteed that air door is opened laborsaving, convenient, flexible.

The specific embodiment
Below in conjunction with accompanying drawing, an embodiment of the present utility model is done to the description into upper step:
The balance air door pneumatic with no pressure that can automatically control of the present utility model, mainly consists of air door, opposed two sects, transmission mechanism 1, locking case 3.On two doorframes 2 at opposed two sects, be respectively equipped with transmission mechanism 1, locking case 3 is established between two doorframes 2 in ground, in locking case 3, be provided with the weight 6 that can replace the quality such as lifting or simultaneously lifting two, two weights 6 are connected with the transmission mechanism 1 on doorframe 2 through wire rope pile warp pulley respectively, between two described weights 6, be provided with the locking inefficacy actuating cylinder 7 being fixed on locking case 3, the push rod of locking inefficacy actuating cylinder 7 is provided with the alternately Breech block 4 of locking of two weights 6 that limits triangular in shape, between Breech block 4 and locking case 3 inwalls, be provided with and recover locking limit spring 5,
Described transmission mechanism 1 comprises that the drive 8, chain 9, drive link 10, actuating cylinder 12, power cylinder joint element for bar 13, the door that are located at a body 17 tops reach a baffle plate 14, bounce cylinder 15, cushion dashpot joint element for bar 16; On door body 17 both sides, top door-hinges 11, be respectively equipped with a drive 8, on two drives 8, coiling has chain 9 respectively, chain 9 two ends are connected with respectively drive link 10, one side of door body 17 is provided with actuating cylinder 12, drive link 10 is connected with the output shaft of actuating cylinder 12 by power cylinder joint element for bar 13, is provided with door and reaches a baffle plate 14 between the output shaft of described actuating cylinder 12 and drive 8; The opposite side of door body 17 is provided with the cushion dashpot joint element for bar 16 being connected with this side drive 8, and cushion dashpot joint element for bar 16 is connected with the output shaft of bounce cylinder 15.
