Description
Technical field
The utility model relates to a kind of fire curtain drive unit.Belong to fire-fighting equipment technology neighborhood.
Background technology
Fire curtain is one of extinguisher that extensively adopts at present as " activity fire separation thing ".Requirement can in time be closed when fire to cut off the intensity of a fire, also requires simultaneously can open easily when needed, goes into interior fire extinguishing with support personnel's safe escape and fire fighter.Existing fire curtain is a non-equilibrium structure, mostly is electronic control.Rolling at ordinary times makes it to remain on opening with an electromagnetic clutch above furred ceiling.Unclamp electromagnetic clutch during fire, roller shutter is closed with the speed decline of 3～7M/min with deadweight.Be to handle the driven by motor roller shutter by control cabinet to scroll up when needing to open.This traditional way requires every grade of fire curtain all must be equipped with a door-rolling machine (being alternating current generator) and a control cabinet.And each floor also must be established a fire-fighting power supply cabinet, each layer power cabinet all needs the cloth service line to the fire-fighting master control room, and the fire-fighting master control room must be set up two-way power supply system independently side by side, one the tunnel is the binary channel power supply system of being supplied with by civil power, and another road is the house generator power supply system.Way like this is no matter be that procuring equipment, application power consumption or layout pipeline all are no small inputs.And the occasion that fire curtain must utilize external force to promote, just behind installation initial stage, each fire-fighting link and fire when mending scene cleaning after going out, and this class situation is just local and of short duration in the life cycle of whole roller shutter, for this reason and the motor, control cabinet and the electric power system that are equipped with are great wastes.Especially I " curtain fire curtain in the curtain " (patent No.: ZL200420060878.6) come out after, the little curtain that personnel can start in the fire curtain during fire passes through, and more need not be equipped with this alternating current generator, control cabinet and electric power system for this reason.
The utility model content
The purpose of this utility model is the above-mentioned shortcoming that overcomes prior art, and a kind of simple in structure, with low cost, practical and reliable electrodynamic type fire curtain drive unit is provided.
This electrodynamic type fire curtain drive unit is by gearbox, driving chain, bitch chain, the motor that has a direct current power supply, the sprocket wheel that is fixed in the motor sprocket on the motor shaft and is fixed on the rolling door drum shaft constitutes, described gearbox partly is made of drive part and gear graduation, described drive part is by casing, be installed in the main shaft in the casing, be installed in the power input sprocket on the main shaft, the gear that has the increment freewheel clutch of a magnet control formula relieving mechanism and be arranged on spindle nose constitutes, described gear graduation part is by the gearing shaft that is installed in the casing, power output shaft, be installed in the travelling gear that is meshed with gear spindle nose on the gearing shaft, be installed in the gear wheel on the power output shaft, be installed in constituting on the gearing shaft with gear wheel pinion in mesh and the power output sprocket that is installed on the power output shaft, described driving chain is overlapped between the power output sprocket of sprocket wheel on the drum shaft and gearbox, and bitch chain is overlapped between the power input sprocket and motor sprocket of gearbox.
When fire takes place, the same with prior art, give signal by master control room by address module, drive magnet is handled relieving mechanism and is discharged the increment freewheel clutch, makes each be in rotary state automatically, and roller shutter can descend under the deadweight effect and close.The normal back of recovery electromagnet is handled relieving mechanism resets the increment freewheel clutch, by the driven by motor bitch chain, rolls roller shutter through driving the sprocket rotation on power output sprocket and then the drive drum shaft after the gear graduation.Also motor-driven partly can be broken away from bitch chain in case of necessity, by artificial pulling bitch chain rollable roller shutter in the same old way.The benefit of doing like this is that an available motor is equipped with many fire curtain drive units.
The rotation of sprocket wheel can be with the counter-rotating of motor when avoiding roller shutter to descend, a sprocket wheel freewheel clutch that has a magnet control formula relieving mechanism is set for described power input sprocket, when fire takes place, magnet control formula relieving mechanism makes the sprocket wheel freewheel clutch break away from sprocket wheel, sprocket wheel can not rotate thereupon when being roller shutter decline, thereby pull bitch chain and also can not rotate, motor just can not reverse thereupon yet.
Still the speed in the time of can on described main shaft, being provided with a centrifugal braking average rate device with the decline of control roller shutter.
Can resemble and set travel switch the existing door-rolling machine, when roller shutter decline/rising puts in place, make roller shutter stop decline/rising by travel switch.
Compared with the aforementioned existing similar products, the utility model has the advantages that simple in structure, technology maturation, reliable in action; The motor that utilization has a direct current power supply provides the power of rolling roller shutter, can charge with assurance motor reliably working to dc source at any time, thereby not need to lay power line, and making and use cost all decline to a great extent.Be particularly suitable for curtain formula fire curtain outfit use in the curtain.
Content of the present utility model further illustrates with the following Examples.
