Abstract
The utility model provides an air window precisely regulated by using air-compression power in order to solve the problem that the ventilation of the existing coal mine air door is hard to adjust. The air window precisely regulated by using the air-compression power comprises an air window outer frame, an adjusting plate and an air cylinder for driving a rotating shaft; the adjusting plate is connected with the air window outer frame through the rotating shaft; and the fixed end of the air cylinder is fixed on the air window outer frame, and the movable end of the air cylinder is connected with the rotating shaft. When two or more adjusting plates are adopted, all the adjusting plates are connected in series with one another through one connecting rod. High-pressure air energy in an air-compression pipeline arranged in a well alley is supplied to the air cylinder by using a high-pressure hose, so a piston of the air cylinder is pushed to move, the air cylinder pushes the rotating shaft to rotate to change the angle of the adjusting plate; therefore, the air-passing amount of the air window can be controlled. The air window precisely regulated by using the air-compression power has a simple structure, is convenient, safe and reliable in construction and convenient in operation, and can shorten the air adjusting time effectively, enhance the adjusting precision of the air amount, increase effective air amount of a mine well and guarantee stability and normality of a ventilating system of the mine well.
Description
Technical field
The utility model relates to a kind of ventilation installation, specifically is to utilize the air regulator of pressing pneumatic power accurately to regulate under a kind of coal mine.
Background technology
Adjusting air regulator operated by rotary motion under the coal mine is on the top of fire dam or air door, higher apart from roadway floor, when needs are regulated air quantity, the staff is in order to reach the requirement of technical indicators such as the air quantity of transferring the wind zone, blast, wind speed, the wind plate is transferred in the installation and removal of need ascending a height repeatedly, gives and transfers the staff of wind to bring certain difficulty and hidden danger; And original accent wind is loaded down with trivial details, and the distinguished and admirable technical data precision that plate is regulated is not high.
Summary of the invention
The purpose of this utility model is to solve the problem that present colliery air door ventilates and is difficult to regulate, and a kind of air regulator of pressing pneumatic power accurately to regulate that utilizes is provided.
For achieving the above object, the technical solution adopted in the utility model is: a kind of air regulator of pressing pneumatic power accurately to regulate that utilizes, comprise air regulator housing and adjustable plate, adjustable plate is connected on the air regulator housing by rotating shaft, also comprise the cylinder that drives rotating shaft, the fixed end of cylinder is fixed on the air regulator housing, and the movable end of cylinder is connected with rotating shaft.The air regulator housing is inlayed and is fixed on fire dam or the air door, the high pressure wind energy of utilizing high-pressure hose will be arranged in the air line in the roadway supplies in the cylinder, the motion of promotion cylinder piston, cylinder promote rotating shaft and rotate the change of realization adjustable plate angle, control the size that air regulator is crossed air quantity with this.
According to the actual air volume of roadway, under the situation that an adjustable plate can not be satisfied the demand, the quantity that adjustable plate is set is two or more, and all adjustable plates are by a connecting rod series connection.As long as the rotating shaft of one of them adjustable plate is connected with the movable end of cylinder, just can realizes the interlock of all adjustable plates.
Characteristics of the present utility model are: (1) is simple in structure, easy construction, safety, reliable, can eliminate the personal height job safety and threaten, and reduces labor strength and saves manpower, and can recycle, and saves financial cost; (2) easy to operate, can effectively shorten and transfer the wind time, and improve the control accuracy of air quantity greatly, increase the effective wind rate of mine, guarantee the stable normal of mine ventilation system.
The utility model can be applicable to the down-hole need install the place of regulating air regulator and air line being arranged.The adjusting air regulator that suitable drift section is big, the place that air quantity is big, the air regulator inside and outside differential pressure is big is passed through in the tunnel, frequent needs are transferred the wind place between especially suitable shaft station, the group tunnel, coal seam, between the tunnel, panel.The present technique project can be used on permanent fire dam and permanent air door, and plank fire dam or plank air door are not suitable for using.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Among the figure, 1-air regulator housing, 2-adjustable plate, 3-rotating shaft, 4-cylinder, 5-connecting rod, 6-ears bearing, 7-slot.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is done and to be specified.
As shown in Figure 1, a kind of air regulator of pressing pneumatic power accurately to regulate that utilizes described in the utility model, comprise air regulator housing 1 and adjustable plate 2, adjustable plate 2 is connected on the air regulator housing 1 by rotating shaft 3, it is characterized in that: also comprise the cylinder 4 that drives rotating shaft 3, the fixed end of cylinder 4 is fixed on air regulator housing 1, and the movable end of cylinder 4 is connected with rotating shaft 3.
Air regulator housing 1 is to be welded by four channel-section steels, and air regulator housing 1 is inlayed and is fixed on fire dam or the air door, and adjustable plate 2 is fixed on the air regulator housing about in the of 1 between the channel-section steel.Cylinder 4 is parts of pneumatic system, and pneumatic system also comprises high-pressure air hose, presses the wind by-pass cock.Be fixed with ears bearing 6 on the air regulator housing 1, the fixed end of cylinder 4 is connected on the ears bearing 6.The high pressure wind energy of utilizing high-pressure hose will be arranged in the air line in the roadway supplies in the cylinder, the motion of promotion cylinder piston, cylinder promotes turning cylinder and realizes that the adjustable plate angle changes, by the stroke size of pressing the wind by-pass cock to regulate cylinder 4 pistons, control the size that air regulator is crossed air quantity with this.
When the quantity of adjustable plate 2 was two or more, all adjustable plates 2 were by 5 series connection of a connecting rod.Adjustable plate 2 is by the plank of equidimension, and the plank two ends are welded with rotating shaft slot 7, is provided with ball bearing in the slot 7.Adjustable plate 2 can require to increase or reduce quantity according to the roadway actual air volume, also can require to increase or reduce the length and the width of adjustable plate according to the roadway actual air volume.During actual the use, the width that every adjustable plate is set usually is 150mm, and length is 450mm, and thickness is 20mm.
Claims (2)
