Abstract
The utility model relates to a mine downhole air door device, including a door frame (7) and a large air door (1). The door frame is connected with the large air door through a hinge, which is characterized in that the large air door (1) has a small air door (2) and the small air door (2) is connected with the large air door (1) through a hinge. The large air door is divided into two parts, the upper active door (3) has a small area, the surrounding of the door is connected with the door frame (7) through a fixed device (6) and the lower door has a big area and is connected with the door frame through a hinge (6). The utility model has the advantages of that the opening of the small door is flexible and portable and is convenient for pedestrian passage and the commonly used large air door do not need to be too big and is convenient for mine car passage in peacetime production. When needed, just open the upper active door to meet requirements of large equipment, greatly reducing air door damage.
Description
(1) technical field
This practical ventilation equipment under a kind of coal mine, particularly a kind of mining down-hole ventilation system throttle setting of newly relating to.
(2) background technology
At present, the coal mining mechanization degree is more and more higher, and large-scale high-yield and high-efficiency mine constantly increases, and the air quantity that the down-hole needs is very big, and the required resistance that overcomes is also very big.Along with the extensive use of large-scale synthesis winning equipment, being positioned at down-hole connection roadway ventilation equipment is that air door often needs to do very greatly, just satisfies the needs that main equipment passes through.Because underground air door both sides blast is big, and the deadweight of air door is also big, opens very inconvenient, to underground labour's walking with produce to pass through and put to no little inconvenience with mine car; The frequent unlatching of air door simultaneously also is easy to cause air door to damage, and brings hidden danger also may influence the safety in production of mine to ventilation system.
(3) technology contents
For solving the defective that its above existing mine exists with air door, the utility model provides a kind of mining underground air door device.
The utility model has solved a difficult problem according to technical scheme as described below.At first, open little air door again on existing big air door, this little air door is connected with big air door by hinge.The second, big air door is divided into upper and lower two parts, the top movable door-plate is less, and the door periphery is fixedlyed connected with doorframe by fastening devices; The lower part door-plate is bigger, is connected with doorframe by hinge.The 3rd, the fixing reinforcing rib in the side of gate panel, hinges fixing fixes on the reinforcing rib and with doorframe and is connected.
Superior part of the present utility model is: wicket is opened flexible, light, is convenient to the pedestrian and passes through; That it goes without doing again is very big for big air door commonly used, convenient produce at ordinary times in the passing through of mine car; The movable doorboard of opening top when needing satisfies the requirement that main equipment passes through; Can significantly reduce the damage of air door.
(4) description of drawings
Accompanying drawing is a structural representation of the present utility model.
1, big air door; 2, little air door; 3, movable plank; 4, reinforcing rib; 5, the fastening devices of movable plank; 6, hinge; 7, doorframe.
(5) specific embodiment
Static structure of the present utility model is referring to accompanying drawing.At first, offer little air door 2 on existing big air door 1, this little air door 2 is connected with big air door 1 by hinge 6.The second, big air door 1 is divided into upper and lower two parts, top movable door-plate 3 is less, and the door periphery is fixedlyed connected with doorframe 7 by fastening devices 5; The lower part door-plate is bigger, is connected with doorframe 7 by hinge 6.The 3rd, the fixing reinforcing rib 4 in the side of gate panel, hinge 6 is fixed on the reinforcing rib 4 and with doorframe 7 and is connected.
At first, 2 of little wind are opened the correct position at big air door, and to make things convenient for the pedestrian by being as the criterion, the pedestrian need not to use very big strength just can open little air door generally speaking.When by mine car, open big air door again, so both convenient, flexibly, reduced the big air door of frequent unlatching again and the air door that causes damages.The second and since main equipment general only when work plane is installed and remove just by air door, be that mine car in the daily production passes through air door at ordinary times.Therefore when making air door, only consider and to get final product by mine car, and be divided into two parts up and down at air door, a portable plate 3 is installed on top, good with bolt at ordinary times, when treating by main equipment, only need take off movable plank and get final product, and equipment fixes by the movable plank that in time will pull down after finishing.Significantly reduce the specification that air door is made like this, its deadweight is reduced, opened lightly, made things convenient for passing through of mine car at ordinary times.
Claims (3)
1, mining underground air door device comprises doorframe (7) and big air door (1), is connected through the hinge between doorframe and the big air door, it is characterized in that opening on big air door (1) fan little air door (2) again, and this little air door (2) is connected with big air door (1) by hinge.
2, mining underground air door device as claimed in claim 1 is characterized in that described big air door (1) is divided into upper and lower two parts, and top movable door-plate (3) area is less, and door periphery is fixedlyed connected with doorframe (7) by fastening devices (6); The lower part door-plate is bigger, is connected with doorframe by hinge (6).
3, mining underground air door device as claimed in claim 1 or 2 is characterized in that in the side of gate panel fixedly reinforcing rib (4), and hinge (6) is fixed on reinforcing rib (4) and goes up and be connected with doorframe (7).
