Description
Technical field
The utility model is related to a kind of Air Throttle in Mine Pit, and in particular to a kind of belt-type automatically resets Air Throttle in Mine Pit.
Background technology
Air door is facility indispensable in mine ventilation system, its main function is：Separate tunnel distinguished and admirable or
Limit tunnel by air quantity, create conditions for mine air distribution according to need, while do not interfere the positive normal open of pedestrian and mine car again
It crosses；At present, the mining depth in colliery is more and more deeper, and underground ventilating institute required airflow increase, ventilation resistance increases therewith, mine pressure
Corresponding increase, the open and close for causing traditional air door are relatively difficult.
Utility model content
The technical problems to be solved in the utility model is to provide a kind of simple and strong in structure, open and close for underground ventilating to hold
The easy Air Throttle in Mine Pit to automatically reset.The Air Throttle in Mine Pit in order to solve the above technical problems, a kind of belt-type of the present invention automatically resets,
Including doorframe, damping buffering band, magnet, pulley, door handle, air door, fixed wall, circuit, switch, explosion-proof motor, spring leaf,
Belt, transmission gear, belt fixing device；Several pulleys are installed in the air door lower end, and damping buffering is installed at two air door closures
Band, installs several magnet in damping buffering band, and the doorframe is arranged on air door upper end, an explosion-proof motor is installed among doorframe
And two transmission gears, driving gearshaft drive both sides belt to rotate.The spring leaf be mounted on driving gearshaft inside with
Each axis is mutually fixedly connected and as the rotation of transmission gear is compressed or is stretched.The switch is arranged on inside and outside the two of fixed wall
Side, air door make air door to both sides horizontal movement under the action of explosion-proof motor drives belt by the traction of belt fixing device,
Applying a starting force by the elastic force and explosion-proof motor of spring leaf makes air door be moved to by-level and in the attraction of magnet
It realizes and closes under power, so as to fulfill the opening and closing of air door.
Compared with prior art, the utility model have the advantage that for：The utility model stable structure is secured, design
Rationally, the utility model is equipped with automatic switch device.It is more convenient using the initial driving force of motor and the elastic force of spring leaf
Automatically reset, solve the problem of opening and closing of existing air door is difficult, time-consuming and laborious, and air door can not automatically reset.
Description of the drawings
Fig. 1 is the structure chart of the utility model；
Fig. 2 is the drive mechanism figure of the transmission device of the utility model；
Wherein, 1- doorframes, 2- damping buffering bands, 3- magnet, 4- pulleys, 5- door handles, 6- air doors, 7- fix wall, 8-

Specific embodiment
It should be appreciated that specific embodiment described herein is only used to explain the utility model, it is not used to limit this
Utility model.
As depicted in figs. 1 and 2, a kind of belt-type automatically resets Air Throttle in Mine Pit.Including doorframe 1, damping buffering band 2, magnet
3, pulley 4, door handle 5, air door 6, fixed wall 7, circuit 8, switch 9, explosion-proof motor 10, spring leaf 11, belt 12, driving cog
Wheel 13, belt fixing device 14；Several common pulleys 4 are installed in 6 lower end of air door, and damping buffering band is installed at two air door closures
2, several magnet 3 are installed in damping buffering band 2, the doorframe 1 is arranged on 6 upper end of air door, and installation one is explosion-proof among doorframe 1
Motor 10 and two transmission gears 13, driving gearshaft drive both sides belt to rotate.The spring leaf 11 is mounted on driving cog
Axle interior is mutually fixedly connected with each axis and as the rotation of transmission gear is compressed or is stretched.The switch 9 is arranged on fixed wall
Inside and outside body 7, air door 6 makes air door under the action of explosion-proof motor 10 drives belt 12 by the traction of belt fixing device
To both sides horizontal movement, applying a starting force by the elastic force and explosion-proof motor of spring leaf makes air door 6 be transported to by-level
It moves and is realized under the attraction of magnet (3) and closed.So as to fulfill the opening and closing of air door.
When opening air door 6, press and release the button 9, explosion-proof motor 10 is rotated with nutating gear 13, in leading for belt 12
Draw effect lower belt fixing device 14 and pull air door to both sides horizontal movement, while compression spring leaf 11, it is appropriate when moving to
Apart from when, motor automatic stop rotates locked transmission gear means and transmission gear 13 is avoided to be generated under the action of spring leaf 11 instead
To movement；When closing air door 6, close button 9 is pressed, locks and releases, explosion-proof motor 10 rotates backward, while spring leaf 11
Band nutating gear 13 rotates, to by-level under the pre- power that air door 6 is given under the elastic force of spring leaf 11 with explosion-proof motor 10
Movement, until magnet 3 attracts each other and reaches close reset.
