Abstract
The utility model relates to a chain driven slide air door, which is characterized in that the air door takes the suspended structure of an upper track and chain traction. A chain drive device is arranged on a machine base swinging from top to bottom; a load regulating device limiting the maximum trailed load of a chain is arranged below the machine base; the limitation is realized by regulating the downward pressure of a heavy hammer or a spring to limit the upward swing of the machine base. An overload limit switch arranged on the machine base is mutually matched with the load regulating device to realize accurate overload protection. The lower end of the air door is provided with a vertical miller which runs along slide rails arranged at both sides of the air door. A photosensitive sensor arranged on the air door can be matched with a computer to realize automatic control. The utility model has the advantages of simple and reliable whole driving structure, little driving resistance and accurate driving position and overload control.
Description
Technical field chain drive push-and-pull throttle of the present utility model belongs to the air door that is used to control ventilation in mine or tunnel.
Background technology adopts motor-driven electronic self closing door, have the transmission efficiency height, simple in structure, be easy to realize the advantage of control automatically.But, the Motorized Operated Damper of prior art is to adopt the continuous rope transmission, its structure is that the driving wheel of a band " V " shape groove is installed on the output shaft of reductor, continuous rope is a wire line thimble that the head and the tail articulating forms, one end of electrodeless becket bridle winds with one circuit half on " V " of driving wheel shape groove, the other end of electrodeless becket bridle adopts the rope sheave that spring is housed that continuous rope is strained, continuous rope constitutes frictional drive with the driving wheel that has " V " shape groove, two pectinid doors are stuck on two strand steel wire ropes up and down of electrodeless becket bridle, drag air door by continuous rope and realize the unlatching of air door or the motion of closing, the size of its driving force is by the tension force and the decision of the friction factor between continuous rope and driving wheel " V " the shape groove of back-moving spring.The shortcoming of this transmission is: (1) is because the size of frictional force is difficult to accurately control, so in transmission, exist the phenomenon of " skidding ", its drawing force and transmission position are all inaccurate, thereby be difficult to the accurately pulling force of control air door and the load of motor, air door often occurs and draw motionless or make electromotor overload and the fault that burns out; (2) " V " shape groove and the continuous rope that " skids " to driving wheel all has strong wear; (3) since the be wound with half cycle of continuous rope on " V " shape groove overlaps, the time regular meeting fault and make transmission failure of restricting appears stinging.
The summary of the invention the purpose of this utility model is: the above-mentioned shortcoming and defect of the electronic self closing door that drags at the available technology adopting continuous rope provides a kind of chain drive push-and-pull throttle, the feature of this air door is, change the continuous rope transmission of adopting on the existing electronic self closing door into chain drive, to guarantee the accurately also elimination " skidding " of its transmission position; In order to control the load of the pulling force and the chain drive that drag air door exactly; realize accurate overload protection; the utility model is designed to the support 17 of chain drive the structure that can swing up and down again; and below the swing support, hauled load setting device 18 (movement weight mass or holddown spring) is housed; above swing support 17, limit switch 16 is housed; upwards swing of support when overload takes place makes the limit switch action cut off motor power, realizes overload protection accurately.
The beneficial effects of the utility model are:
1, simple and reliable for structure, easily to make, the transmission resistance is little, and fault is few.
2, chain drive, position are accurately non-slip.
3, transfer to carry apparatus structure simple, transfer carry accurately, overload protection is sensitive reliable.
4, drive mechanism is simple, automatic control easy to implement.
Description of drawings Figure of description: the general structure conceptual scheme that is chain drive push-and-pull throttle of the present utility model.
The specific embodiment is dug the air door chamber in the both sides at installing air door place, tunnel, be embedded with guide rail bearing 1 at the top at chamber two ends, I-shaped steel guide rail 6 is installed on bearing, two fan push-and-pull throttles 7 are lifted on it on i iron guide rail by roller 5, on the floor of air door lower end, be provided with trench, be embedded with slide rail 22, two pectinid badges in the both sides of trench between two slide rails, in the air door lower end edger roll 21 is housed, air door is sliding between two slide rails under the guide effect of edger roll.At the right-hand member of guide rail 6 right changed course sprocket wheel 2 is installed, upper left changed course sprocket wheel 11 and lower-left changed course sprocket wheel 23 is installed at the left end of guide rail.Swing support 17 is installed on the floor of left side chamber, the left end of support and fixed bearing 13 are hinged, below the support right-hand member, be provided with the supporting leg 19 of adjustment height, so that when maintenance with sole plate supports on the floor, and the bearing height of adjustable complete machine seat, the degree of tightness of being convenient to when maintenance, to change chain or adjusting chain.Chain drive 12 is installed on the support 17 that can swing up and down.Drive sprocket 14 is installed on the output shaft of chain drive, chain 9 by drive sprocket 14, upper left bend wheel 11, left-hand door draw bail 8, right bend wheel 2, right door draw bail 4, lower-left bend wheel 23, return drive sprocket and form ring-type and connect.Below drive sprocket 14, be equipped with and protect chain cover 15, protect on the bearing gland that chain cover is fixed on chain drive 12 output shafts belows, protect chain cover below sprocket wheel greater than 150 ° less than in 180 ° the scope chain holder being protected on the gear teeth of drive sprocket, can both make chain and sprocket wheel positive engagement no matter guarantee the degree of tightness of chain.The upper end of two pectinid doors is fixed with the chain up and down of chain by left-hand door draw bail 8 and right door draw bail 4 respectively, drags air door by forward and reverse running of chain drive and chain and slides along guide rail, finishes the unlatching of air door or closes.Door open limit switch 10 also is housed respectively on the i iron guide rail and closes door limit switch 3, it is stopped finishing the power supply that cuts off motor when opening the door or closing the door with the control panel switches.Below swing support 17 right-hand members, hauled load setting device 18 is housed; can set up the maximum drawbar pull that drags air door by this device; this setting device can be a movement weight mass; also can be that support is pressed on holddown spring on the floor; overload limit switch 16 is housed above the support right-hand member; in the process of air door, be obstructed or open at switch; it is malfunctioning to close door limit switch 10 or 3; drive sprocket 14 will overcome the set pressure of swing support; (gravity of movement weight mass or the pressure of spring) drive support and whole drive unit along chain upwards swing trigger overload limit switch 16 the motor outage stopped, realizing overload protection accurately.In the bottom of right air door two identical light sensors 20 are housed also, this sensor can send the light signal that receives to computer, realizes the automatic control of air door by the programme-control of computer.
