Description
Technical field
The utility model relates to a kind of air door, belongs to mine ventilation technology field.
Background technology
Air door Main Function in coal mine down-hole tunnel is that obstruct is distinguished and admirable, ensures that ventilation system is normally run.This makes air door both sides produce very large leeway, causes air door to be difficult to open; When personnel are through air door, need just can open air door with the power of more than 90Kg, operation is inconvenience extremely.Can this also brings hidden danger to safety, to the impact of people more than 90Kg when not only closing from air door, or fast and safely withdraw from personnel during the generation disaster of down-hole, all require to re-start appropriate design to air door.
At present, there have been some technician by opening air door with cylinder and linkage, achieved air door and easily opening easily.But still there is following defect in this mode:
1, once cylinder or power pipeline go wrong, will cause difficulty to door opening; Now, in generation mine disaster or when needing personnel to withdraw rapidly, catastrophic consequence is likely caused.
2, install actuating cylinder and need enough spaces, some air door set-point limited space can not install cylinder.
3, cylinder cost is installed higher.
Summary of the invention
The technical problems to be solved in the utility model is: provide a kind of air door for mine, and may occur to open difficulty to solve existing air door, air door set-point limited space can not install cylinder, and the problem such as cost is higher.
Scheme of the present utility model:
A kind of air door for mine, comprises air door body, air door body offers ventilation opening, air door body is also provided with the door and window of enclosed ventilation mouth, and door and window is the switched architecture of the plate face slip setting along air door body.
Preferably, ventilation opening accounts for the 1/3-2/5 in air door entity plate face.
Preferably, ventilation opening is opened in the top of air door body, door and window slides along the vertical direction setting on air door body, also include two lifting ropes, one end of two lifting ropes is fixed with an assembly pouring weight respectively, be positioned on the air door body above ventilation opening and be provided with at least two pulleys, the other end of two lifting ropes is walked around at least one pulley respectively and is individually fixed in the both sides of door and window upper end, the gravity of two assembly pouring weights and be set to G5, the gravity of door and window is set to G3, door and window, lifting rope and the frictional resistance sum suffered by balancing weight are set to F, then G5 is more than or equal to the difference of G3 and F, counterweight is mainly for reducing resistance during sliding door, window, simultaneously, if G5 is less than or equal to G3 and F sum, then need manually to slip off and close the doors and windows, if and G5 is greater than G3 and F sum, then need manually to slip off door and window, door and window can rely on the gravity of balancing weight automatically to close when closing, therefore, preferred G5 is slightly larger than G3 and F sum herein, the automatic closedown of door and window can be realized.
Preferably, totally four, pulley, ventilation opening axis is vertically set to a, four pulleys are symmetrical arranged between two along axis a, two assembly pouring weights are arranged at the left and right sides of ventilation opening respectively, and every root lifting rope walks around two pulleys of balancing weight side corresponding to this lifting rope, and two permanent positions of lifting rope on door and window are also symmetrical along axis a, the weight of two assembly pouring weights is identical, and the weight of every assembly pouring weight can both adjust as required.
Preferably, be provided with hollow interlayer in door and window body, door and window slides and arranges with in hollow interlayer;
Preferably, the left and right sides of door and window is provided with roller, and door and window is arranged on door and window body by roller-coaster;
Preferably, balancing weight is also provided with roller, balancing weight is also arranged on door and window body by roller-coaster; Balancing weight is equipped with roller, during owing to installing air door, air door is closed and the angle that tilts to direction of closing the door automatically in order to realize, in this case, the frame that the roller of roller and door and window just can ride over air door body both sides slides, and swing effect when simultaneously also prevent balancing weight suspention reduces frictional resistance.
Preferably, the rear and front end of door and window is provided with handle;
Preferably, door and window is also provided with link, the corresponding clamp being provided with fixing link on air door body.When staff will pass through air door, first a hand is caught handle to be pulled by door and window downwards and is opened door and window, and then pull with another or push away air door, air door will be opened easily.When personnel are by after air door, decontrol handle, door and window is closed automatically due to the pulling force by balancing weight, and air door also can be closed because of part leeway and deadweight of tilting voluntarily, complete operation.When staff one portable thing be inconvenient to open air door time, first can be opened by door and window, then hang on clamp by link button, fixing door and window makes it stay open state, then pushes away or pulls open air door.After air door, take off link, make air regulator, air door closes automatically, complete operation.
Preferably, ventilation opening is opened in the bottom of air door body, and door and window slides along the vertical direction setting on air door body;
Preferably, ventilation opening is opened in left side or the right side of air door body, and for long 1.8 m × high 2.2 m of air door specification, the specification of ventilation opening is more than or equal to long 0.8m × high 2.0m, and window slides in left-right direction setting on air door body.
The beneficial effects of the utility model:
Because air door is all in a high negative pressure state usually, cause opening air door resistance very large, this causes air door to be difficult to the main cause of opening.In order to reduce the pressure differential of air door both sides, we select on air door, offer a door and window, and due to law of connected vessels, when window is opened, the pressure differential of air door both sides can reduce, and then it is just easier to open air door.Wherein it should be noted that, air door generally arranges twice, and spacing is generally several meters, the limited space between twice air door, so when air regulator is opened, the pressure differential of air door both sides can reduce very soon.
Compared with prior art, major advantage is as follows for the utility model:
1, ventilation opening and supporting gliding window are set on air door, i.e. door and window, can open quick, easy, effortlessly or close air door, under emergency case, it is more reliable and secure and cost is lower, when being not suitable in the place of some tunnel limited length, narrow space cylinder is installed, preferablyly select this air door simultaneously;
2, this air door can be designed to multiple different structure according to the glide direction of the position of ventilation opening and door and window, and each structure respectively has pluses and minuses, can be in optimized selection according to on-the-spot air door particular location situation;
3, this air door can with air cylinder driven with the use of, improve the safety of air cylinder driven air door.
