Abstract
The utility model provides an underground vehicle passing ventilation door which comprises a door body hinged on a door frame. The underground vehicle passing ventilation door is characterized in that a window is arranged in the door body. Pressure relief casements are arranged on the window. Air pressure is effectively reduced through the pressure relief casements so that the vehicle passing ventilation door can be opened easily and flexibly, the opened vehicle passing ventilation door does not need to be pressed by manual power, labor intensity of workers is effectively reduced, the requirement for air distribution according to needs is satisfied, ventilation effect in a working site is improved and transportation of mine transportation vehicles is guaranteed. After the vehicle passing ventilation door is closed, a closing state of the vehicle passing ventilation door is maintained with the assistance of air. The underground vehicle passing ventilation door has the advantages of being simple in structure, convenient to operate, rapid in pressure relief, easy to open and the like.
Description
Technical field
The utility model relates to a kind of air door, and the car air door is crossed in especially a kind of down-hole, belongs to mining facility technology field.
Background technology
During underground mining, need in the mining transport channel, air door be set, in order to guaranteeing that the mining ventilation is simultaneously normal, conveniently transport the ore of extraction.The opening direction of existing underground air door all with the air intake opposite direction, guarantee closing of air door with the pressure by wind, but when blast is excessive, be difficult to by manually opening the door, and need by manually pinning air door after opening the door, could allow like this mine truck pass through.Not only labour intensity is large, and causes easily the security incident of air door and a mine truck collision because of misoperation.Therefore, be necessary prior art is improved.
Summary of the invention
Normally close for the assurance underground air door, conveniently open the door simultaneously and transport ore, the utility model provides a kind of down-hole that can effectively reduce the pressure that opens the door to cross the car air door.
The utility model provides a kind of like this down-hole and crosses the car air door, comprises the door body that is hinged on the doorframe, it is characterized in that a body is provided with window, window is provided with the pressure release sash, so that before opening air door, moves first and opens the pressure release window, after allowing blast reduce, can easily open air door.
The top and bottom of described window are provided with chute, and the upper and lower end of pressure release sash places respectively chute corresponding to window, open and close with the slip that makes things convenient for the pressure release sash.
Described window is arranged on the top of a body, perhaps bottom, and perhaps middle part, perhaps upper and lower portion are to be used for pressure release.
The utlity model has following advantages and effect: adopt such scheme, namely first by behind the effective pressure reduction of pressure release window, can open easily, neatly the car air door, and need not manually to pin the excessively car air door after opening, effectively reduce workman's labour intensity, and guaranteed to cross the requirement that the car air door divides wind as required, the operation field ventilation effect is improved, ensure simultaneously the transportation of mine truck, and after crossing the car air door and closing, still can guarantee by the pressure of wind the closed condition of air door, have simple in structure, easy to operate, pressure release is quick, the advantage such as easily open the door.
Description of drawings
Fig. 1 is the structural representation of the utility model.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described further.
Such as Fig. 1, the car air door is crossed in the down-hole that the utility model provides, comprise the doorframe 1 that is installed on the drive 7, be hinged on the door body 2 on the doorframe 1, door body 2 is provided with window 4, and window 4 is provided with pressure release sash 5, and the top and bottom of described window 4 are respectively equipped with chute 3,6, the upper and lower end of pressure release sash 5 places respectively the chute 6,3 of window 4 correspondences, opens and closes with the slip that makes things convenient for pressure release sash 5; Described window 4 is arranged on the top of a body 2, to be used for pressure release.Before opening car air door door body 2, first mobile pressure release sash 5, opening window 4, allow blast reduce after, can easily open the car air door.
