Description
Technical field
The utility model is related to rolling screen door technical field, more particularly to a kind of pair of curtain double track fire resistance rolling shutter door.
Background technology
Fire resistance rolling shutter door is a kind of fire fighting device suitable at the larger hole of building, except the use for possessing common rolling screen door
Place is outer, also with fire prevention, every the specific function of cigarette, suppression fire spread.In order to obtain preferable flameproof effect, existing one kind is adopted
It is used for electronic pair of curtain double track fire resistance rolling shutter door of the track that door curtain is slided, this electric fireproof curtain door with two door curtains, two
Lifting is driven by a flame-retardant door driving machine, and door roller drives two spool turns by chain-drive mechanism, and reel drives twine respectively
The door curtain being wound on reel slides up and down to realize switch gate along door curtain guide rail.Door roller be provided with limiter, limiter and
The output shaft of door roller is by gear drive, when door curtain is raised or lowered to stop position set in advance, and limiter can be to
Rolling door machine controller sends electric signal, and rolling door machine controller, which is connected to after electric signal, to control door roller to stop operating, so that door
Curtain is parked in stop position set in advance automatically.Existing pair of curtain double track fire resistance rolling shutter door is directly connected using two sprocket wheels with chain
Connect, two sprocket wheels are linkages, two door curtains can only Simultaneous Switching, it is impossible to separate operation, because measurement, processing and installing is missed
Difference, two door curtains are difficult often that when closing rolling screen door, a door curtain is closed in place, another door curtain while being automatically stopped in place
Often there is gap with ground, influence flameproof effect.
Secondly, occur fire as common rolling screen door in use, also wanting two rolling screen door of Simultaneous Switching no, make rolling door
Machine is operated under larger load, is influenceed the life-span of door roller, is also wasted electric energy.
In addition, by door curtain effect of weight, door roller will not only overcome the friction between transmission mechanism, door curtain and door curtain guide rail
Power, will also overcome the weight of rolling screen door, and it is continually changing during being supported on switch gate, when just opening the door, door curtain deadweight
Larger, door roller load is maximum, and with the rising of door curtain, the load of door roller constantly reduces；At closing time then on the contrary, just closing the door
When, the load of door roller is maximum, and with the decline of door curtain, the load of door roller constantly mitigates, or even the deadweight of door curtain can drive
Door roller is rotated.The power of door roller will be configured according to its maximum load, otherwise can not open rolling screen door, and power is bigger,
Power consumption is bigger；Secondly, during work, even if load reduction, door roller will be also operated on lowest power, cause electricity
The waste of energy, increases expense.
Further, door roller, which is typically carried, pulls chain for opening Door by Hand, but present many rolling screen door are in order to ensure safety,
Wicket is not provided with rolling screen door, indoor the manually opened roller shutter of chain is pulled so still cannot be introduced into when running into power failure
Door；Secondly, pull rolling screen door with pulling chain, due to will be by door roller gearbox, chain gear transmission, speed reducing ratio is larger, opens
The speed for opening rolling screen door is very slow, wastes time and energy.
Utility model content
The utility model overcomes the deficiencies in the prior art can be such that two rolling screen door are all automatically stopped in place there is provided one kind
