Abstract
The utility model relates to a controller for a scrolling door, which is a controller capable of scrolling and closing the door outdoors conveniently when in power supply and power failure. A long sleeve 5 is respectively welded with the end plate of each spring box or the end plate of a chain wheel 4 into integration in segment and rotates round a fixed core shaft 7 synchronically. A manual clutch device is composed of a chain wheel 3, a worm wheel 2, a clutch shaft 10, a manual shifting fork 11 and a spring 9. The manual shifting fork is also installed outdoors, so the scrolling door can be electrically operated and manually operated when the door is closed or scrolled; the manual-operation can achieve the labor-saving effect.
Description
The utility model relates to a kind of volume brake control device, and particularly a kind of can the convenience when having a power failure in indoor and outdoor opened a sluice gate volume brake control device with barrier gate.
At present, the rolling-gate that building is installed and used when running into power failure, is often opened a sluice gate in the pulling mode of the manual chain of indoor employing.Because common structure is to adopt a fixing mandrel, dependence is welded in the effect of the spring force of a plurality of spring cases on the mandrel and rolls up lock automatically, reason owing to process and assemble, each spring case volume lock is not to carry out synchronously, some is fast, some is slow, make the volume lock asynchronous up and down, increase volume lock resistance at transverse direction.Therefore, be by pulling the auxiliary volume of chain lock.Such result is not only time-consuming but also require great effort.Particularly the people is positioned at when outdoor, and buttoned-up rolling-gate is felt simply helpless especially when having a power failure.By retrieval, the patent of having applied for mainly is to consider anti-theft feature, does not solve the problem that occurs when having a power failure.
The purpose of this utility model is a kind of improved volume brake gear, and it can be opened a sluice gate and barrier gate easily, particularly also can open a sluice gate easily and barrier gate outdoor when having a power failure.
The technical solution of the utility model is achieved in that and adopts the manual clutch device in worm type of reduction gearing and chain gear transmission, and the both ends of the surface side plate of a plurality of spring cases all is linked to be integral body with long sleeve, rotate together with sprocket wheel drive long sleeve and spring case, carry out barrier gate and open a sluice gate.
When having a power failure, make arrangement of clutch be in released state by manual shift fork, because the end face side plate of a plurality of spring cases is linked to be an integral body by long sleeve, do not produce distortion.So open a sluice gate with the barrier gate process in, under the acting in conjunction of spring force, the volume lock rotates easily synchronously, resistance is very little.Therefore, successfully roll up lock, can save original manual chain apparatus simultaneously, simplify the structure.
The utility model has the advantages that:
1, when having a power failure, can make the rolling-gate opening and closing easily, reach the labour-saving effect.
2, when having a power failure, also can open a sluice gate easily and barrier gate, and save manual chain apparatus outdoor.
1 couple of embodiment of the present utility model is described in detail below in conjunction with accompanying drawing.
Accompanying drawing is a structural representation of the present utility model.(rolling-gate is in minimum closed condition)
This rolling-gate control device comprises parts such as the reducer is made up of worm screw 1 and worm gear 2, (worm screw is not drawn motor by motor drives among the figure) clutch shaft 10, manual shift fork 11, sprocket wheel 3 and 4 (chain does not draw), long sleeve 5, spring case 6, fixed central spindle 7, rolling-gate 8, spring 9.Sprocket wheel 3, worm gear 2, clutch shaft 10, manual shift fork 11 and spring 9 are formed the manual clutch devices.With hand rotation manual shift fork, state as shown, manually shift fork is pushed clutch shaft to move to left to, the key of clutch shaft enters in the keyway of worm gear, and the axle head of clutch shaft is combined with the axle head of sprocket wheel 3, when manually shift fork rotated 90 °, clutch shaft moved to right under the effect of spring 9, the key of clutch shaft breaks away from the keyway of worm gear, and worm gear separates with sprocket wheel.
Fixed central spindle 7 is fixed, is supporting rolling-gate 8.Adorned 4 groups of rolling bearings in fixed central spindle 7, the outer ring of bearing is fixedly connected with the end plate endoporus of sprocket wheel 4 and three spring cases 5 respectively.Long sleeve 5 is divided into three sections end plate welding that become sprocket wheel 4 respectively with the end plate of three spring cases, and long sleeve, three spring cases and sprocket wheel are linked to be an integral body, thereby can synchronously rotate around fixed central spindle 7.
During normal power supply, worm gear engages with sprocket wheel 3, and worm screw is rotated, and drives worm gear reducer and rotates, and sprocket wheel 3 rotates by chain drive drive sprocket wheel 4 and rotates, and rotates thereby drive long sleeve, realizes the opening and closing of rolling-gate.
When having a power failure, manually shift fork turns over 90 °, under the elastic force of spring 9 clutch shaft is moved right, and key on the clutch shaft and the disengagement of the keyway of worm gear make the clutch axle head also throw off with the axle head of sprocket wheel 3 thereby sprocket wheel 3 separates with worm gear.Under the spring force effect of spring case, open a sluice gate automatically.In like manner, also can hand pulling downwards be closed by rolling-gate.
In addition, because manually shift fork is operated easily, also can open a sluice gate without.
If rolling-gate can increase the quantity of spring case when heavier greatly, the quantity of corresponding increase rolling bearing, long sleeve 5 segmentations are linked to be an integral body with the end plate of each spring or the end plate welding of sprocket wheel 4 respectively.
