Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As shown in Figure 1 to Figure 3, a kind of mine fan air door apparatus for fast switching, comprise doorframe 1 and air door 2, described doorframe 1 is arranged on air outlet 3, doorframe is " day " font, and doorframe is divided into two parts by the segmentation post 11 be arranged in the middle of doorframe 1, and these two parts are corresponding two ventilation openings 41 and 42 respectively, the centre of one of them side of doorframe 1 is provided with motor 5, and the output shaft of motor connects a gear 6;
Air door 2 comprises a body 21 and guide wheel group 22, and guide wheel group 22 is arranged on the both sides of a body 21, the guide wheel of guide wheel group 22 can in doorframe 1 side roll;
The side of door body 21 has tooth bar 23, and gear 6 is stretched into by the centre of doorframe 1 and engages each other with the tooth bar 23 on door body 21.
Gear 6 is connected on the output shaft of motor 5, along with motor operations, gear 6 rotates thereupon, as shown in Figure 5 and Figure 6, gear 6 engages with tooth bar 23, and gear 6 rotating band carry-over bar 23 moves, because tooth bar 23 is connected to the side of a body 21, so motor 5 can drive whole air door 2 to move, thus realize the switching of air door fast.
As shown in Figure 6 and Figure 7, door body 21 is made up of grid framework 21-1 and the door-plate 21-2 being laid on framework surface, and described grid framework 21-1 is spliced by square hollow section.
The mode that door body 21 adopts grid framework and door-plate to combine, alleviate the weight of whole air door, hollow grid framework plays skeletal support effect simultaneously, makes a body more durable; And grid framework is spliced by hollow section, further mitigate air door weight.
As shown in Figure 9 and Figure 10, the outside of described doorframe 1 is made up of channel-section steel I12 and channel-section steel II13, and inner side is made up of a pair angle steel 14, square shaped hollow section I15 and two square shaped hollow section II16; Segmentation post 11 is made up of a square shaped hollow section.
