Description
Technical field
The utility model is related to mine air door, and specially pressure balance type is to open air door.
Background technology
Underground coal mine panel track lane uses the wooden air door of twice, bears and transports the weight such as material, discrepancy of pedestrian
Appoint.Because the wooden air door of twice is bivalve door, it is made by door band and plank, when workman is come in and gone out with haul, is both needed to
Left and right two is opened simultaneously fans door.When air door is remarkable, because blast is very big, open the door and at closing time, it is often necessary to which two people complete,
Cause high effort for, come in and go out very inconvenient, and wooden air door process is cumbersome, installs, dismounting trouble, with standardisation requirements not
Symbol, not can be recycled also, waste very big.
The content of the invention
The utility model is in order to solve the above problems there is provided pressure balance type to open air door.
The utility model adopts the following technical scheme that realization：Pressure balance type to open air door, including left air door and
Horizontal left socle and right support is separately installed with right air door, left air door and right air door, left socle and right support are respectively and left
Air door and right air door are be arranged in parallel and spaced apart, and lower-left axis pin base and bottom right are respectively fixed with left socle and right support
The lower end of axis pin base, left bearing pin and right bearing pin is inserted respectively into the pin shaft hole of lower-left axis pin base and bottom right axis pin base, left bearing pin
In the pin shaft hole that upper left axis pin base and upper right axis pin base are inserted respectively into the upper end of right bearing pin, the head of upper right axis pin base and connecting rod
The tail end connection of end connection, upper left axis pin base and connecting rod, lower-left axis pin base and upper left axis pin base are located at the left side of left air door.Use
When, employee draws left air door or pushes away right air door, and another air door is open in the presence of connecting rod, it is only necessary to which a people just can be by air door
Open.
Above-mentioned pressure balance type is to open air door, and the left end of left air door, which is provided with pulley, pulley, is wound with steel wire rope, steel
One end of cord is connected with counterweight, the middle-end connection of the other end and left bearing pin.There is counterweight by pulley system on bearing pin, can basis
Air force, voluntarily adjusts the weight of counterweight, it is ensured that pedestrian can completely close by rear air door.
Above-mentioned pressure balance type is to open air door, and left air door and right air door are made by steel body structure welding.
The air door that the utility model is provided all is made by steel body structure welding, and recycling rate is 100%, can be saved
Save processing and the maintenance cost of substantial amounts of wooden air door；The trip of workman is facilitated, substantial amounts of human cost has been saved.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
In figure:The left air doors of 1-, the right air doors of 2-, 3- left socles, 4- right supports, 5- lower-lefts axis pin base, 6- bottom rights axis pin base, 7-
Left bearing pin, the right bearing pins of 8-, 9- upper lefts axis pin base, 10- upper right axis pin bases, 11- connecting rods, 12- pulleys, 13- counterweights.
Embodiment
Pressure balance type is separately installed with left air door 1 and right air door 2 to open air door, including left air door 1 and right air door 2
The left socle 3 and right support 4 of level, left socle 3 and right support 4 be arranged in parallel with left air door and right air door and are spaced certain respectively
It is respectively fixed with distance, left socle and right support under lower-left axis pin base 5 and bottom right axis pin base 6, left bearing pin 7 and right bearing pin 8
End is inserted respectively into the pin shaft hole of lower-left axis pin base and bottom right axis pin base, and the upper end of left bearing pin 7 and right bearing pin 8 is inserted into upper left
In the pin shaft hole of axis pin base 9 and upper right axis pin base 10, the head end connection of upper right axis pin base 10 and connecting rod 11, the He of upper left axis pin base 9
The tail end connection of connecting rod 11, lower-left axis pin base 5 and upper left axis pin base 9 are located at the left side of left air door 1.
Above-mentioned pressure balance type is to open air door, and the left end of left air door 1, which is provided with pulley 12, pulley 12, is wound with steel wire
Rope, one end of steel wire rope is connected with counterweight 13, the middle-end connection of the other end and left bearing pin 7.
Above-mentioned pressure balance type is to open air door, and left air door 1 and right air door 2 are made by steel body structure welding.
When it is implemented, on the left side fixed block support of left air door, pulley bracket fixed block pin, pulley is arranged on
On pulley pin；Connecting rod 11 is chosen as sleeve pipe；Air door doorframe uses 14# channel-section steels, and all parts of air door are connected by screw bolts, and transports
It is defeated, install, dismantle it is very convenient.
