Abstract
The utility model discloses double-leaf heterotrophic wind doors which are wind doors used for the underground ventilation system of a coal mine. The double-leaf heterotrophic wind doors are opened heterotropically, a four-bar mechanism using two door pivots as two rotary pairs is arranged on the upper parts of two doors, and a resetting device composed of a spring or a pulley and a heavy bob is connected between a hinge and the cantilever arm of one end of a door frame. The utility model can be used under the two conditions such as positive and inverse wind and can not be influenced by wind pressure, opening force is little. The problems such as the partition of the positive and inverse wind, large impact force of door closing, etc. can be solved by one door, people's safety of door passing is ensured, and the service lives of the wind doors are extended.
Description
The utility model relates to the air door of mine ventilation system.
The ventilation system of present China's coal-mine down-hole, such as the lower end that transporter is gone up a hill, the top of ginney, parking lot, middle part etc. is located, all do not allow wind circulation but need the pedestrian or the tunnel of driving in, mostly adopt positive and negative twice air door structure, the per pass air door is for singly opening or two opening.Though such air door solved the positive and negative wind direction in down-hole every the wind problem, but still exist be subjected to that influenced by wind pressure is big, opening force is big, the unsafe problem of the personnel that move into one's husband's household upon marriage.
It is little that the purpose of this utility model provides a kind of opening force, and can solve the single track air door of positive and negative wind direction every the wind problem.
For achieving the above object, the utility model adopts the double door structure, two door-hinges are installed in opposite location, two fan doors can incorgruously be opened, and to adorn one be the four-bar mechanism of two revolute pairs on the tops of two fan doors with two door-hinges, two rocking arms in the four-bar mechanism can be shaft-like or the level triangle shape, and leg-of-mutton one side is connected with door-plate.The resetting means that air door is in often close also is equipped with at one end hinge place of connecting rod, and this resetting means can be made up of tension spring, and the one end is connected with hinge, and the other end is connected with the cantilever arm of doorframe; Also can be made up of pulley, weight, pulley is fixed on the cantilever arm of doorframe.
Can adorn the adjustable pipe that can regulate length of connecting rod on the above-mentioned connecting rod, the adjustable pipe two ends are threaded with two sections connecting rods, and lock with locking nut.
Owing to take above measure, four-bar mechanism is formed two fan doors the linked system of one incorgruous unlatching, distinguished and admirable righteous style and practice or the inverted ventilation situation of no matter being in, blast acts on power on the air door, and always equal and opposite in direction, direction are opposite, so both solved positive and negative wind direction every the wind problem, realized again door opening not wind-engaging to the ideal state of, influenced by wind pressure, thereby solved the personnel's that move into one's husband's household upon marriage safety problem.
Below in conjunction with drawings and Examples the utility model is further described.
Fig. 1 is the attached view of the biparting incorgruous air door of the utility model.
In Fig. 1, door leaf 1 and door leaf 2 adopt steel design, and handgrip 10, two door leafs respectively are housed above, and each is connected with 13 hinges with door-hinge 3; The installation site direction of two door-hinges is opposite, and door leaf 1 and door leaf 2 are opened in the opposite direction.Adorning one is the four-bar mechanism of revolute pair on two fan door tops with two door-hinges, and wherein two rocking arms 7 and 11 can strike out triangle with steel plate, and each level of one side of each rocking arm and two fans are connected with screw, and each corresponding angles is connected with 12 with connecting rod 9 usefulness hinge axis 6; The round steel of connecting rod 9 usefulness φ 45 is made, and divides and do two sections, and intermediate thread connects an adjustable pipe 8 by steel pipe manufacturing.At hinge axis 6 places, draw one to be that weight 15 is arranged, and pass through the steel wire fly 14 of pulley 5, pulley 5 is contained on the cantilever arm of doorframe 4.
