Description
The technical field is as follows:
the invention relates to a coal mine air door, in particular to a safety air door capable of being opened in a labor-saving manner, and belongs to the technical field of coal mine ventilation equipment.
Background art:
the basic tasks of a mine ventilation system are: enough fresh air is supplied to the underground to meet the requirement of personnel on oxygen; poisonous and harmful gas and dust in the well are diluted, and the safe production is ensured; the underground climate is adjusted, and a good working environment is created. The main function of the ventilation facility is to control the flow direction of the underground air flow, so that the air flow flows according to a specified route, the effective air quantity of each working place is ensured, and finally the stability and reliability of the underground ventilation system are ensured.
The air door is the most common type in underground ventilation facilities, and must be manufactured and constructed strictly according to the requirements of coal mine safety regulations. The dampers do not allow wind to pass through, but must be placed in roadways that require pedestrians or traffic. The air door is required to be tightly closed and does not leak air, so that the stability and reliability of a mine ventilation system are ensured, and the safety production requirement of a mine is met. The air door can be freely opened and closed, and the safety of passing of personnel and vehicles is ensured. The thickness of the door leaf is not less than 50mm, and the whole body is very heavy. When workers pass through the mine air inlet and return system, the workers need to pass through a communication roadway with ventilation facilities (air doors) and can pass through the communication roadway after the air doors are manually opened. When opening the air door that contact lane both ends negative pressure differential is less relatively, very can easily open the air door and pass through, nevertheless when passing through main air inlet and return system contact lane, because contact lane both ends negative pressure differential is great, alone open the air door very difficult, and have the safety risk, need several people to make power or use the lever principle simultaneously and just can open the air door with the help of the crowbar.
The high negative pressure pneumatic double-cylinder traveling crane air door is a ventilation facility adopted by a modern large mine, and in the daily production and use process, the pneumatic air door is complex in mechanical and electrical circuits and often fails, so that vehicles cannot pass through the air door.

The opening and closing state of the door body is detected by a travel switch, and each air door is mutually locked. The air door can be opened and closed by a manual button or manually. The opening operation of the air door is controlled by an opening and closing button arranged on the door body, and the opening and closing button is connected with a pneumatic device. The two dampers are locked to each other, i.e. only one damper is allowed to be open at a time.
The air door is provided with a wind shield; the wind shields are arranged in the middle of the two air doors and are respectively fixed on one opposite sides of the two air doors; the wind shield is made of waste conveying belts, the height of the wind shield is matched with that of the air door, and the wind shield is used for better sealing when the air door is closed;
the pressure relief air window is arranged at the upper part of a door body, a handle is arranged on the pressure relief air window, and the pressure relief air window is fixed on the door body through a hinge; when the pressure difference in the roadway is too large, the pressure relief air window can be opened first, and then the air door is pushed and pulled easily;
the pedestrian air door is arranged on the other door body, and pedestrians can pass through the pedestrian air door;
the automatic control system comprises a driving system and a switch button;
and the electric valve controls the push-pull air door to be opened or closed according to the received operation instruction.
The auxiliary component comprises an underground chamber dug on a coal (rock) wall; when the air door is opened, the air door is embedded in a coal (rock) wall between the main transport channel and the return air channel; when the air door is closed, the air door is ejected from the inside of the coal wall, and the two air doors are shielded by the wind shields to realize sealing under the condition of positive and negative wind.
The invention adopting the technical scheme has the following beneficial effects:
1. the fixed pulley slides on the rail, so that the opening force is small, and underground workers can smoothly open the air door;
2. the impact force is small, the air door is not influenced by external weather conditions, and the air door is safe, reliable and not easy to deform;
3. the door has longer service life and better sealing performance;
4. the pressure borne by the air door can be adjusted through the pressure relief air window.
The foregoing shows and describes the general principles, essential features, and advantages of the invention. It will be understood by those skilled in the art that the present invention is not limited to the embodiments described above, which are merely illustrative of the principles of the invention, but that various changes and modifications may be made without departing from the spirit and scope of the invention, which fall within the scope of the invention as claimed.
