The specific embodiment
The embodiment of the invention comprises the roller 1 of being located at bearing 6 downsides, in order to the drive unit and the self-locking device of driving rolls, it is characterized in that: described drive unit comprise kink on roller wheel shaft 2 in order to the gear 31 that is connected with motor output device 5 and with so that gear and roller and rotating shaft thereof are in the interlock or the active connection of linkage status not.
Described active connection is for being located at roller wheel shaft middle part chute 21 interior its axially movable feather keys 32 relatively, corresponding respectively offering with feather key stretched out the conduit 33,11 that the outer end of roller wheel shaft cooperates on the described gear end face adjacent with roller, and be located at conduit 11 axial lengths on the roller greater than the axial length of feather key outer end, one end of described chute is provided with in order to promote feather key to axially movable screw rod 34 of the other end and the tapped through hole 22 that is mated, and the other end of chute is provided with the back-moving spring 35 that acts on the feather key opposite side.When rotating screw bolt makes it outwards move to certain position, feather key loses the thrusting action power of screw rod, so under the effect of back-moving spring in the gear direction moves to the conduit that its end enters gear, gear, roller, roller wheel shaft three are in the state of combination at this moment, must come driven gear and roller forward or reverse by the motor output device, thereby the driving gate body opens the door or closes the door; And when having a power failure, rotatable screw rod moves inward it, promoting feather key way roller direction by screw rod moves to feather key and breaks away from conduit on the gear, at this moment, because gear that is connected with the motor output device and roller and rotating shaft thereof are in released state, therefore roller and roller wheel shaft are free to rotate, thereby the user can manually promote a body switch.
For the ease of controlling the mobile vertically stroke of feather key and limiting its beat up and down, the middle part of described feather key is provided with locating slot 37, be provided with the alignment pin vertical 36 in the locating slot with feather key, alignment pin can move axially along roller wheel shaft in locating slot, locating hole 23 on the two ends of alignment pin pass locating slot and are located at roller wheel shaft is connected, displacement by alignment pin qualification feather key can limit the distance that screw rod moves inward like this, thereby prevents that it from continuing to move inward the damage that causes internal construction.
Above-mentioned self-locking device comprises perpendicular to be located at resilient push 41 on the bearing, to be located at ratchet 42 and self-locking card wheel 43 on the roller wheel shaft, to be articulated in the resilient push lower end in order to the ratchet 44 that cooperates with ratchet and be fixedly arranged on the make-up buting iron 46 that cooperates in order to the Access Division 45 with the self-locking card wheel on the ground, a sidepiece and resilient push lower end hinged (jointed shaft 47) that described self-locking card is taken turns.
Be connected with gear for the ease of feather key, the conduit 33 on the described gear oppositely is provided with two outer ends of stretching out roller wheel shaft for being the cross conduit that the center is symmetrically distributed with the axial line on the described feather key.
Position with back-moving spring for the ease of feather key and to be connected, the opposite side of feather key is provided with the protuberance 38 that cooperates the feather key that connects with the centre bore of back-moving spring.
Shown in Fig. 6,7, the A/F of the Access Division 45 of self-locking card wheel is little than the hole insied width, makes it when fastening make-up buting iron 46, can make make-up buting iron 46 no matter from all taking turns 43 from self-locking card up and down the locking of make-up buting iron; The hinged jointed shaft 47 in self-locking card wheel and resilient push lower end can drive resilient push and move up and down, thereby the drive ratchet moves up and down and ratchet is played stop or disengaging effect.
During use, the outermost below that this device is installed in vertical hinged door can be used, and its use is described as follows:
Close the door:
Instruction door machine drives, gear, roller, roller wheel shaft are in bonding state by the effect of feather key at this moment, therefore the motor output device just changes by gear driven roller and roller wheel shaft, the door body is pushed into the position of closing the door, after the self-locking card wheel brushes up against the make-up buting iron that is embedded in ground, from transferring to insert in the catching groove of make-up buting iron, the rotation of self-locking card wheel simultaneously pulls down the dynamic elasticity push rod, depress the ratchet on the resilient push, ratchet is inserted in the tooth of ratchet, force roller wheel shaft to stop operating, limit switch action at this moment, make power-off, door is locked.
Open the door:
The reverse driving of instruction door machine, owing to gear, roller, roller wheel shaft still are in bonding state, so the motor output device drags the and then reverse of self-locking card wheel and ratchet simultaneously by gear driven roller and roller wheel shaft reverse.Owing to be provided with the spring 48 of ratchet between the medial extremity of ratchet and the resilient push, can push ratchet open when therefore ratchet reverses, thereby unclamp resilient push, resilient push promotes under himself spring action automatically, drive to move on the ratchet and break away from ratchet fully, the self-locking card wheel reverses the make-up buting iron that the back breaks away from ground simultaneously, and door is opened.
During power failure, switch to manual operation.
Open Door by Hand:
And when having a power failure, with the unlock key rotary screw it is moved inward, promoting feather key way roller direction simultaneously moves to feather key and breaks away from conduit on the gear, at this moment, because gear that is connected with the motor output device and roller and rotating shaft thereof are in released state, therefore roller and rotating shaft thereof are free to rotate, the body thereby the user can manually push the door open.
Manually close the door:
Fastening position pushes, the self-locking card wheel brushes up against the make-up buting iron on ground and rotates voluntarily, insert in the notch of make-up buting iron, and pull down the dynamic elasticity push rod, depress ratchet, make itself and ratchet to buckling, afterwards, with the unlock key rotary screw it is outwards moved, feather key promptly enters in the conduit of gear under action of reset spring automatically, make gear, roller, roller wheel shaft three be in bonding state, thereby realize closing the door function.
