Description
Technical field
The utility model relates to a kind of electric soft roller shutter door.
Background technology
Existing electric soft roller shutter door mainly is made of driver, bracing frame, door-hinge, cylinder, door curtain, crossbeam and doorframe, driver connects with door-hinge, door-hinge is fixedlyed connected with cylinder, door curtain twists on the cylinder, crossbeam is fixed on the door curtain bottom, and cylinder to door curtain both sides between crossbeam and crossbeam two ends place in the doorframe.When opening the door, driver drives door-hinge and cylinder rotate, and cylinder winds up door curtain, at closing time, the driver counteragent, door curtain is by the limited gravity fall of crossbeam.Above-mentioned electric soft roller shutter door is widely used in needing to intercept fast the place of door both sides environment, as the inlet of logistic warehouse, outlet etc.There is following defective in the electric soft roller shutter door of this structure: defective one, because the door curtain that is wound on the cylinder is to lean on the limited gravity of crossbeam to haul downwards, when door curtain is closed condition, there are two defectives, the one, door curtain is under the effect of blast, and mid portion is easily arrived the doorframe outside by wind, simultaneously, under the lifting that door curtain makes progress, crossbeam also can built on stilts, causes door curtain to be not closed completely; The 2nd, after overcoming the limited gravity of crossbeam, can artificially easily open.Defective two, because the gap of crossbeam in doorframe is bigger, in the open and close process, door curtain can be swung with the crossbeam all around.Defective three, because door curtain is freely to reel by cylinder, the swing of crossbeam in addition, door curtain is easily inclined to one side by volume in winding process.
Summary of the invention
The technical problems to be solved in the utility model provides a kind of high-stability electric soft roller shutter door, the door curtain that can solve existing electric soft roller shutter door easily be blown out doorframe, the lattice that are not closed completely, easily artificially opened, door curtain is swung with crossbeam, and door curtain is easily rolled up defectives such as inclined to one side.
The scheme of the utility model technical solution problem is to adopt driver, bracing frame, door-hinge, cylinder, door curtain, crossbeam and doorframe constitute high-stability electric soft roller shutter door, place, two ends at door-hinge is equipped with drive sprocket respectively, the bottom of doorframe inboard is equipped with driven sprocket, all be wound with a driving-chain between the drive sprocket of every side and the driven sprocket, the two ends of crossbeam are connected with the driving-chain of both sides respectively, connect by bearing between door-hinge and the cylinder, be wound with spring on the door-hinge, afterburning cover is housed on the door-hinge, one end of spring connects afterburning cover, the other end connects cylinder, horizontal backing pin is housed on cylinder, vertical backing pin is housed on the door-hinge, laterally backing pin intersects corresponding with vertical backing pin position, the reference diameter of drive sprocket is greater than the initial diameter of cylinder, less than the diameter behind the cylinder coiling door curtain.After installing, close door curtain, make spring produce the torsion of upwards straining door curtain by the reinforcing cover, and lock onto on the door-hinge (at this moment, because of crossbeam has been fixed on the driving-chain, door curtain on the crossbeam hauls cylinder downwards always, make spring can't discharge torsion), regulate the vertical backing pin on the door-hinge, make it stop horizontal backing pin on the cylinder, to stop cylinder to be subjected to blast and to discharge door curtain, vertical backing pin is lock onto on the door-hinge (when the door curtain closed condition, because cylinder can't discharge door curtain because of backing pin stops, the cylinder of this position is equivalent to fixedly connected with door-hinge, under this state, with door-hinge and driven sprocket is axle, has formed the ring of a closure that is made of door curtain and driving-chain at two between centers, at this moment, when blast acted on door curtain on the closed hoop, the door curtain middle part can not be by wind to the doorframe outside, crossbeam can not move up; Because there is braking mechanism in driver, can not upwards lift door curtain easily), door curtain is in opening procedure, and by driver drives door-hinge and drive sprocket and driving-chain, crossbeam is with upwards operation of driving-chain.Since the reference diameter of drive sprocket greater than cylinder initial diameter, the first half term of action, the air line distance of drive sprocket walking is greater than the air line distance of cylinder walking, laterally backing pin under the effect of spring with vertical backing pin apart from increase, the second half of action, owing to successively twine door curtain on the cylinder, it is big that diameter of cylinder becomes, the air line distance that the air line distance of drive sprocket walking is walked less than cylinder gradually, laterally backing pin is with vertically backing pin is apart from dwindling, and when being rolled onto desired location on the door curtain, laterally backing pin abuts in again with vertical backing pin, at this moment, cylinder will be rolled up on the door curtain.
In order to prevent from the cylinder to occur in the rolling door curtain process all around swing appears in inclined to one side phenomenon of volume and crossbeam in running phenomenon, be separately installed with a guide rail parallel on two driving-chain next doors with driving-chain, roller is equipped with at the two ends of crossbeam respectively, and roller moves on guide rail.In the door curtain motion process, be subjected to the constraint of guide rail, the inclined to one side and all around swing of restriction door curtain volume.
Wherein, the relation between drive sprocket reference diameter and the diameter of cylinder can be drawn by following formula:
d＝D+2(n-1)k
In the formula:
D---drive sprocket reference diameter, the mm of unit.
D---diameter of cylinder, the mm of unit.
N---cylinder rotating cycle.
K---door curtain thickness, the mm of unit.
Spring also can be that torsion spring or scrollwork advance spring.
Drive sprocket, driven sprocket and driving-chain structure also can be synchronous cog belt, wire rope or other rope class,
The utility model electric soft roller shutter door can prevent to prevent that door curtain from swinging with crossbeam because wind effect is not closed completely effectively, prevents the artificial door curtain of opening arbitrarily, and door curtain can be fast, steadily open, closure, and service behaviour is safe and reliable.
