Abstract
The utility model relates to a horizontal pull type and reverse direction air door with two swings in mines. When people pass through the air door or when they pull or push the air door, the air door will be opened and at the same time, the vertical shaft of the air door is driven to rotate in the same direction as the chain wheel arranged at the top of the vertical shaft, which further coincidentally drive the chains to move; the chains cause the chain wheel arranged at the top of the vertical shaft of the other swing and the vertical shaft to rotate in the same direction while the other swing is reversely opened as the pulled or pushed air door; the people pass through the air door, the side of the air door heading against the wind can be automatically closed due to the large pressure of wind imposed thereon; when the wind comes from a reverse direction, the direction of wind flow changes, and under such circumstance, the opening and closing of the air door can be realized on the same principle as when the air door withstands head-on wind blows.
Description
Technical field
The utility model relates to a kind of coalmine ventilation air door, belongs to the mine ventilation structure.
Background technology
The mine universal air door adopts flat push type two road air doors at present, and the per pass air door also should be provided with reverse throttle except that being equipped with the forward air door, uses during in order to the disaster inverted ventilation.Actual mine tens road air doors must manually go to control when the generation disaster needs inverted ventilation, change reverse throttle.Under the situation that disaster takes place, manually go to handle and change reverse throttle, can cause bigger accident.So, real difficult realization of disaster inverted ventilation.For this reason, must develop and a kind ofly close automatically, no matter the air door that righteous style and practice or inverted ventilation can both use to guarantee carrying out smoothly of inverted ventilation, is guaranteed the reliable of mine ventilation safety and disaster inverted ventilation.
Summary of the invention
Solution of the present utility model is that air door adopts the biparting reverse geometry of horizontal sliding, and air door door-plate (1), (2) are installed in respectively on the vertical shaft (3) and (4) on the doorframe.Two fan door-plates can be realized folding along vertical shaft (3) and (4) rotation.Sprocket wheel (5) and (6) are equipped with in the top of vertical shaft (3) and (4).Two sprocket wheels with electrodeless chain (7) around, chain (7) moves in chain support slot (8).The upper and lower side of vertical shaft (3) is equipped with spiral stretching device (9) on vertical shaft, in order to stretching chain (7).Fashionable mutual overlap joint is being closed in air door door-plate (1) and (2), and the doorframe upper and lower frames has door-plate positive stop strip (10), closes tight in order to guarantee the air door overlap joint.
When the people pushes away (drawing) moving air door by air door, this air door is opened, drive the vertical shaft rotation simultaneously, the sprocket wheel and the air door on vertical shaft top rotate in the same way, and drive chain movement, sprocket wheel and vertical shaft that chain drives the vertical shaft top of another pectinid door simultaneously rotate in the same way, then another pectinid door be pushed the air door reverse opening that (drawing) opens.
Because the air door door leaf overlaps a pectinid door real area, cross the wind area greater than the opposite side air door, so no matter wind direction how, under mine ventilation pressure, can make air door close automatically or keeps closed condition.
Beneficial effect
The utility model has following advantage:
1, adopts the biparting reverse throttle structure of horizontal sliding, forward air door and reverse throttle can be united two into one,, can both guarantee the reliability of ventilation system no matter forward ventilates or inverted ventilation, can not rouse the door that blows in and cause the ventilation short circuit, destroy ventilation system because of the change of ventilation wind direction.
2, the utility model can be merged into two road universal air doors with two road forward air doors and two road reverse throttles, has saved air door one.
3, the utility model is owing to adopt the biparting reverse throttle structure of horizontal sliding, all the same use with inverted ventilation of forward ventilation, the harmfulness that prevents disasters and cause because of the manual switching reverse throttle when taking place.
4, the utility model adopts the biparting reverse throttle of horizontal sliding, can realize the air door auto-closing.
Description of drawings:
Do following detailed description the in detail below in conjunction with accompanying drawing and specific implementation method:
The biparting reverse throttle arrangement diagram of Fig. 1-colliery horizontal sliding.
The biparting reverse throttle structure chart of Fig. 2-colliery horizontal sliding.
Among the figure:
1-air door door-plate (left side)
2-air door door-plate (right side)
3-vertical shaft (left side)
4-vertical shaft (right side)
5-sprocket wheel (left side)
6-sprocket wheel (right side)
The 7-chain
8-chain support slot
9-vertical shaft spiral stretching device
10-air door positive stop strip
The specific embodiment:
Illustrated colliery air door adopts the biparting reverse geometry of horizontal sliding, and air door door-plate (1), (2) are installed in respectively on the vertical shaft (3) and (4) on the doorframe.Two fan door-plates can be realized folding along vertical shaft (3) and (4) rotation.Sprocket wheel (5) and (6) are equipped with in the top of vertical shaft (3) and (4).Two sprocket wheels with electrodeless chain (7) around, chain (7) moves in chain support slot (8).The upper and lower side of vertical shaft (3) is on vertical shaft spiral stretching device (9), in order to stretching chain (7).Fashionable mutual overlap joint is being closed in air door door-plate (1) and (2), and doorframe keeps off up and down in door-plate positive stop strip (10) lining.
When the people pushes away (drawing) moving air door by air door, this air door is opened, drive the vertical shaft rotation simultaneously, the sprocket wheel and the air door on vertical shaft top rotate in the same way, and drive chain movement, sprocket wheel and vertical shaft that chain drives the vertical shaft top of another pectinid door simultaneously rotate in the same way, then another pectinid door be pushed the air door reverse opening that (drawing) opens.
Because the air door door leaf overlaps a pectinid door real area, cross the wind area greater than the opposite side air door, so no matter wind direction how, under mine ventilation pressure, can make air door close automatically or keeps closed condition.
Claims (1)
1. biparting reverse throttle of colliery horizontal sliding, it is characterized in that: air door door-plate (1), (2) be installed in respectively on the vertical shaft (3) and (4) on the doorframe, two fan door-plates can be along vertical shaft (3) and (4) rotation, realize folding, sprocket wheel (5) and (6) are equipped with in the top of vertical shaft (3) and (4), two sprocket wheels with electrodeless chain (7) around, chain (7) moves in chain support slot (8), the upper and lower side of vertical shaft (3) is equipped with vertical shaft spiral stretching device (9), in order to stretching chain (7), fashionable mutual overlap joint is being closed in air door door-plate (1) and (2), and the doorframe upper and lower frames has door-plate positive stop strip (10).
