Abstract
A pneumatic automatic air door comprises an air door. An air pressure cylinder is mounted on the outer side of the air door, and a pull rod head of the air pressure cylinder is connected with the air door through a steel wire rope. The air pressure cylinder is further connected to an air pressure pipeline through a reversing valve. The pneumatic automatic air door is convenient to use and maintain, flexible to move, safe and reliable. By the aid of the pneumatic automatic air door, safe production of a mine is more guaranteed, labor is reduced, and transporting efficiency is improved.
Description
Technical field
The utility model belongs to coalmining safety facility, relates in particular to a kind of air-driven type air door.
Background technology
The coal mine lower wind door all is vital link for mine ventilation safety and production and transport system; Mainly be that what to adopt is manual control switch's common air door for a long time; Because big lane has more in high blast district; Key elements such as the air door area is big cause the door opening resistance too big, in addition single through the time strength is too little can't open.Optimize the mine ventilation facility, guarantee mine ventilation system reliable and stable be a important process in the Coal Production, it is related to worker's the physical and mental health and the safety in production of mine.Want to carry out the management work of mine ventilation facility, will constantly improve, adjust and optimize the mine ventilation facility.
The utility model content
The utility model problem to be solved is the actual conditions that combine adjustment of projecting mine ventilation system and mine ventilation facilities management work, utilizes compressed air pipe line to work out a kind of air-driven type self closing door.
Adopt following technical scheme in order to solve the problems of the technologies described above: a kind of air-driven type self closing door, comprise air door, in the air door outside blast cylinder is installed, blast air cylinder tie rod head is connected with air door through wire rope; The blast cylinder is connected on the compressed air pipe line through reversal valve.
Described reversal valve is hand-operated direction valve or solenoid operated directional valve.
Described solenoid operated directional valve is the 3 position-5 way solenoid operated directional valve.
The gauge tap of described 3 position-5 way solenoid operated directional valve is two groups, is separately positioned on the air door both sides.
The utility model is easy to use, is convenient to safeguard, and flexible movements, safe and reliable.Guarantee the safety in production of mine more, reduced manual work, improved conevying efficiency.
Description of drawings
Fig. 1 is the structural representation of the utility model.
The specific embodiment
As shown in Figure 1, a kind of air-driven type self closing door comprises air door 1, in air door 1 outside blast cylinder 2 is installed, and the drawhead 3 of blast cylinder 2 is connected with air door 1 through wire rope 4; Blast cylinder 2 is connected on the compressed air pipe line 6 through 3 position-5 way solenoid operated directional valve 5.The gauge tap 7 of reversal valve is two groups, is separately positioned on the air door both sides.
When pedestrian or tank car through the time, gauge tap is beaten to running position, thereby this is the blast cylinder interior because of the air pressure of compressed air pipe line ejects cylinder that wire rope pulling air door fixing on the drawhead is opened, and at this moment gauge tap is returned the neutral position; After pedestrian and tank car normally pass through the gauge tap of air door opposite side is beaten to fastening position, at this moment the blast cylinder interior discharges air pressure, and drawhead is contracted to initial position, and wire rope is removed the pulling force to air door, and air door is closed automatically.
The utility model mainly is applicable to the setting of ventilation equipment in pedestrian tunnel, driving tunnel and the shared tunnel of people's car and the adjustment of ventilation system etc., can utilize blast to realize the air door automatic shutter according to vehicle and walk situation.Can satisfy the inverted ventilation needs of mine, even also can be under the calm state of air line by opening and closing manually.
