Description
Technical Field
[0001] The present invention relates to the technical field of coal mine ventilation, and particularly to a mine-used lifting type air regulating window. Background Art
[0002] The mine-used air regulating window is an important device in the mine ventilation system, and is mainly used in the ventilation systems of production sites such as the development, preparation, and coal mining of underground coal mines and non-coal underground mines to adjust and control the air volume, so as to effectively control the air volume distribution in the mine. At present, most of the underground are manual air regulating windows or flap type air regulating windows. In actual applications, there may be problems such as high labor intensity, large maintenance workload, irregular air regulating window openings, and inaccurate calculation of the regulating openings. With the continuous expansion of the production scale of underground mining, the continuous upgrading of intelligence and digitization, and the continuous improvement of environmental protection requirements, higher requirements are also put forward for the performance and quality of the mine-used air regulating window.
[0003] The existing manual air regulating window cannot achieve timely control in the opening and closing adjustment, and cannot accurately adjust the opening size of the air regulating window in terms of adjustment accuracy. At the same time, it will also increase the labor volume of the mine workers. Moreover, only the opening and closing of the manual air regulating window in the mine cannot perform air exchange adjustment and air volume distribution in time through the air regulating window in case of gas leakage and other conditions, which is likely to cause underground ventilation accidents.

For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific situations.
[0019] Since manually adjusting the air window requires the staff to manually adjust the opening and closing of the air window, timely control cannot be achieved in terms of the adjustment of the ventilation volume, and accurate adjustment cannot be achieved in terms of the adjustment accuracy. At the same time, it will also increase the labor intensity of the mine personnel. And in the event of gas leakage and other situations, if the air window cannot be adjusted in time for ventilation adjustment and air volume distribution, it is easy to cause underground ventilation accidents; in view of this, the inventor of the present application provides a mine-use lifting type adjustable air window, which can reduce the calculation amount of the air volume adjuster and improve the adjustment accuracy of the air window at the same time.
[0020] Such as Figure 1-6As shown in the figure, the mine lift-adjustable air window includes a window body 1 and a door body 2. The window body 1 is provided on one side of the door body 2, and the window body 1 and the door body 2 are of an assembled structure. A pedestrian door 4 is provided inside the door body 2; a window cavity 5 is provided in the middle of the window body 1, and an adjustable air window 3 is provided in the window cavity 5. The adjustable air window 3 includes a first air window plate 301, a second air window plate 302, and a third air window plate 303 arranged from top to bottom on one side. Bending hooks are provided at the upper and lower ends of the first air window plate 301, the second air window plate 302, and the third air window plate 303. The first air window plate 301 is connected to the second air window plate 302 through the bending hook, and the second air window plate 302 is connected to the third air window plate 303 through the bending hook; a lifting device 6 is provided on one side of the adjustable air window 3. The lifting device 6 includes a pneumatic motor 601. The pneumatic motor 601 is provided below the interior of the window cavity 5. The output end of the pneumatic motor 601 is connected to a worm and gear reducer 602. A synchronous shaft 603 is provided on the worm and gear reducer 602. Driving pulleys 604 and bearing seats 605 are provided at both ends of the synchronous shaft 603. One side of each bearing seat 605 abuts against the inner wall of the window cavity 5. A guide plate 501 is provided above each driving pulley 604. A synchronous belt tensioning device 608 is provided at the top of each guide plate 501. A driven pulley 607 is provided at the top of each synchronous belt tensioning device 608. Each driven pulley 607 and its corresponding driving pulley 604 are connected through a synchronous belt 606. Each synchronous belt 606 is connected to the end of the first air window plate 301 through a belt fixing device 304. The two synchronous belts 606 are respectively provided at the left and right ends of the first air window 601.
[0021] Based on the above embodiment, the synchronous shaft 603 is supported by the bearing seat 605. The pneumatic motor 601 will not generate sparks, meeting the use conditions in coal mines. The driving reducer is a worm and gear reducer 602, which has a function of self-locking when stopped, and can lock the position of the first air window plate 301 to prevent the change of the ventilation opening area from causing the change of the ventilation volume; when the pneumatic motor 601 operates, the pneumatic motor 601 drives the synchronous shaft 603 to rotate through the worm and gear reducer 602. The synchronous shaft 603 drives the driving pulleys 604 at both ends thereof to rotate, and further makes the driving pulleys 604 drive the synchronous belt 606 and the driven pulley 607 to rotate. The synchronous belt 606 drives the first air window plate 301 to move up and down through the belt fixing device 304, thereby realizing the opening and closing of the adjustable air window 3. The synchronous belt 606 with teeth on the synchronous shaft 603 is used to drive the first air window plate 301 to lift, with high running accuracy, and it is not easy for the first air window plate 301 and the second air window plate 302 to get stuck due to left-right non-synchronization.
[0022] In this embodiment, the first-stage wind window plate 301, the second-stage wind window plate 302, and the third-stage wind window plate 303 are all made of steel. The first-stage wind window 301 and the bending hooks at its upper and lower ends, the second-stage wind window 302 and the bending hooks at its upper and lower ends, and the third-stage wind window 303 and the bending hooks at its upper and lower ends are all integrally formed by sheet metal bending.
[0023] Based on the above embodiment, the first-stage wind window plate 301, the second-stage wind window plate 302, and the third-stage wind window plate 303 made of steel have high strength and can solve the safety problems of flame retardancy, fire prevention, and ventilation in coal mines. The bending hook at the lower end of the first-stage wind window plate 301 overlaps with the bending hook at the upper end of the second-stage wind window plate 302, and the bending hook at the lower end of the second-stage wind window plate 302 overlaps with the bending hook at the upper end of the third-stage wind window plate 303. When the first-stage wind window plate 301 moves downward, the second-stage wind window plate 302 is driven to move downward through the bending hook, opening the regulating air window 3. When the first-stage wind window plate 301 moves upward, the bending hook at the lower end of the first-stage wind window plate 301 contacts the bending hook at the top end of the second-stage wind window plate 302, pulling the second-stage wind window plate 302 to move upward until the bending hook at the lower end of the second-stage wind window plate 302 contacts the bending hook at the top end of the third-stage wind window plate 303, at which time the regulating air window 3 is closed.
[0024] In this embodiment, two guide plates 501 are respectively located at the left and right ends of the regulating air window 3, as Figure 3 、 Figure 4 、 Figure 5 shown. On one side of each guide plate 501, an outer sliding groove 502, a middle sliding groove 503, and an inner sliding groove 504 are vertically opened, and the outer sliding groove 502, the middle sliding groove 503, and the inner sliding groove 504 are evenly arranged on the guide plate 501. Each outer sliding groove 502, middle sliding groove 503, and inner sliding groove 504 is respectively connected to the end of the first-stage wind window 301, the second-stage wind window 302, and the third-stage wind window 303. On the other side of each guide plate 501, it is connected to the inner wall of the window body cavity 5.
[0025] Based on the above embodiment, by vertically opening the outer sliding groove 502, the middle sliding groove 503, and the inner sliding groove 504 on the guide plate 501, the opening and closing of the regulating air window 3 are changed into a linear lifting motion, changing the opening and closing of the regulating air window 3 into a linear continuous variable, reducing the calculation amount of the air regulating personnel, and improving the regulating accuracy of the air window 1.
[0026] In this embodiment, as Figure 6 shown, a sealing strip 201 is provided at the inner frame of the door body 2. A door shaft 401 is installed between the door body 2 and the pedestrian door 4. A concealed door handle 401 is provided on the pedestrian door 4, and a pneumatic lock 403 for locking is installed above the pedestrian door 4.
[0027] Based on the above embodiments, two mine-use lifting adjustable air windows are arranged one after the other in the same mine roadway. When one pedestrian door 4 is opened, the pneumatic lock 403 on the other pedestrian door 4 locks the pedestrian door 4 to ensure that only one of the two pedestrian doors 4 provided in the same mine roadway can be opened at the same time. The two pedestrian doors 4 in the same mine roadway are interlocked with each other to ensure that the two pedestrian doors 4 in the same mine roadway cannot be opened simultaneously, avoiding the air flow short circuit caused by opening the two pedestrian doors 4 in the same mine roadway at the same time, and thus avoiding the disorder of the ventilation system.
[0028] The working principle of the present utility model is as follows: when it is necessary to open the adjustable air window, the pneumatic motor 601 is started. The pneumatic motor 601 drives the synchronous shaft 603 to rotate through the worm and worm gear reducer 602. The synchronous shaft 603 drives the drive pulleys 604 at both ends thereof to rotate, and further causes the drive pulleys 604 to drive the synchronous belt 606 and the driven pulley 607 to rotate. The synchronous belt 606 drives the first-stage air window plate 301 to move downward through the belt fixing device 304, and thus the adjustable air window 3 is opened; when it is necessary to close the adjustable air window, the pneumatic motor 601 is started. The pneumatic motor 601 drives the synchronous shaft 603 to rotate through the worm and worm gear reducer 602. The synchronous shaft 603 drives the drive pulleys 604 at both ends thereof to rotate, and further causes the drive pulleys 604 to drive the synchronous belt 606 and the driven pulley 607 to rotate. The synchronous belt 606 drives the first-stage air window plate 301 to move upward through the belt fixing device 304, and thus the adjustable air window 3 is closed.
[0029] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not used to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features.
