Abstract
Disclosed is the driving device of a main exhaust fan valve for mining, comprising a valve, a driving mechanism and a slide rail. The valve can move on the slide rail. A rack gear is also fixed on the valve. The driving mechanism is provided with an output gear which can be engaged with the rack gear, which enables the valve to move on the slide rail. The drive device enables the valve to conveniently slide on the slide rail, which guarantees the stability of the motion of the valve.
Description
Technical field
The relevant a kind of valve actuator of the utility model refers in particular to a kind of valve actuator that is used in mining main exhauster mouth.
Background technology
Mine underground work dangerous well-known, and an one main hidden danger is that its muddy gas that produces may cause great injury to the personnel of underground work, may be in peril of one's life sometimes.Therefore mining main exhauster plays an important role in underground work, and in order to guarantee the safety of work, two induced draft fans are generally arranged on the ventilating shaft, use one of them, another is standby, so in each blower fan import department a valve need be set, when this channel standby, can use valve closing.Because the valve switch frequency is very low, but reliability requirement is high, so how to make things convenient for and the switch of stable by-pass valve control is very important.Traditional valve switch device has slidingtype and rotary shaft, rotary shaft can need bigger power when carrying out the switching of valve, and rotating valve cover the valve of extracting out can be not easy to operate because of the influence of wind-force, so the slidingtype valve comparatively speaking has laborsaving and stable characteristics.
Traditional slidingtype induced draft fan valve actuator generally is the traction drive by sprocket wheel and steel wire, and under motor drives or manual drives, sprocket wheel rotation winding steel wire impels valve to move by the draw of steel wire.Yet owing to adopt the mode of steel wire traction to have a lot of shortcomings, because expose outside, so steel wire is easily because of the impetus of getting rusty, can not guarantee stability and safety, and it generally has fine motion formula limit switch, and fine motion formula limit switch is malfunctioning easily after long-term the use, so the stability in can not guaranteeing to use.In addition, use the mode of steel wire traction also can make the manual operation inconvenience.
Therefore, if design a kind of handled easily and the stable down-hole induced draft fan valve actuator of long-term functional performance can produce influence greatly to industry.
The utility model content
The purpose of this utility model is to provide a kind of mining main exhauster valve actuator of easy to operate and safety and stability.
The purpose of this utility model is achieved in that a kind of mining main exhauster valve actuator, comprise valve, driving mechanism and slide rail, above-mentioned valve can move on above-mentioned slide rail, it is characterized in that: also be connected with a tooth bar on the above-mentioned valve, driving mechanism has an output gear, output gear can be meshed with tooth bar, impels valve to move on above-mentioned slide rail.
Compared with prior art, the beneficial effects of the utility model are: move on slide rail owing to used the mobile mode of stablizing level and smooth tooth bar engagement to drive valve, so the easy to operate and safety and stability of induced draft fan valve actuator provided by the utility model.
Description of drawings
Fig. 1 is a general structure view of the present utility model.
Fig. 2 is that A-A among the utility model Fig. 1 is to partial sectional view.
Fig. 3 is that C-C among the utility model Fig. 1 is to sectional view.
The specific embodiment
Below in conjunction with drawings and Examples the utility model is further described.
See also Fig. 1, Fig. 2 and shown in Figure 3, mining main exhauster valve actuator of the present utility model has a valve 1, and this valve 1 can laterally slide, and the lower, transverse of valve 1 is connected with a tooth bar 11.Driving mechanism 2 drives by motor (figure do not show) or manual turntable 21, and outputs power to output gear 23 by gear mechanism, output gear 23 can with tooth bar 11 engagements, thereby with transmission of power to tooth bar 11.Valve 1 is arranged on the slide rail 3, and the bottom has a slide mechanism 31, and slide mechanism 31 comprises support portion 311 and movable pulley 313, and described movable pulley 313 passes through 311 fixing backs, support portion by rotation and slide rail 3 relative motions under it.Slide rail 3 is made up of light rail, and above-mentioned movable pulley 313 has groove 315, and groove 315 can be accommodated the first half of light rail wherein, so at the volley the positioning action that can form to a certain extent movable pulley 313.
At work, run motor or rotation manual rotating disk 21 drive tooth bar 11 by output gear 23, thereby valve 1 horizontally slip along slide rail 3, realize the switch of valve 1.
In sum, the utility model has been finished designer's purpose of design, and the switch of induced draft fan valve is convenient and stable, and driving mechanism is closed design, prevent to get rusty, and better maintenance, long-term use also can guarantee its reliability.
