Abstract
The utility model provides a linkage device for an ultra-large fireproof rolling shutter, which comprises a control box, at least two motors and at least two fuse protectors. The motors of the same fireproof rolling shutter are connected in parallel to one another, and each motor is provided with one fuse protector. The fuse protectors are temperature-sensitive glass tube-type fuse protectors, and the individual temperature-sensitive glass tube-type fuse protectors are not connected with the motors and are directly connected with the wires of a storage battery in an intersection manner. The control circuits inside the control box are in twinplex connection with each motor, wherein one loop is connected with the motor through a motor rotation controller and the other loop is connected with the motor through a brake controller. The wires of the storage battery are connected with the brake controller through the intersection points of the temperature-sensitive glass tube-type fuse protectors. During the power failure, when any one of the fuse protectors is fused by the fire, the storage battery supplies the power to the motor brake controller and controls the motor brake controller to open the braking devices of all motors, thereby achieving the linkage of a plurality of motors, allowing the rolling shutter to fall down under the self-gravity and completing the closure of the fire compartments.
Description
Technical field
The utility model relates to a kind of linkage of fire curtain.
Background technology
Regulation according to fire curtain standard (GB14102-2005) 6.4.7 bar, fire curtain should assemble the temperature control releasing device, when the temperature around the temperature control releasing device temperature-sensitive original paper reaches 73 ℃ ± 0.5 ℃, the action of temperature control releasing device, roller shutter should descend according to deadweight and close, all disposed a fuse when therefore, the fire-proof machine of all roller shutters uses dispatches from the factory.
What traditional fuse used is mechanical device, and the brake gear of motor is connected with fuse by wire rope, and behind the disconnected fuse of baked wheaten cake, wire rope unclamps, and causes the brake gear on the motor to be opened, and roller shutter lands under the deadweight effect.With regard to the roller shutter that uses a motor, if the outage of on-the-spot emergency power supply, fuse place temperature reaches 73 ℃ ± 0.5 ℃, and fuse will disconnect, and cause the brake gear of motor to be opened, and roller shutter will be closed under the deadweight effect automatically.But it is when a door frame roller shutter uses multiple electric motors,, independently of one another between the fuse because of every motor has all disposed a fuse.When fire only blows a fuse, this fuse only can be opened the brake gear of corresponding motor, and other adjacent motors do not blow because of fuse, and brake gear can not be opened, and can't realize that roller shutter relies on deadweight to realize the target that descends.
The utility model content
The utility model provides a kind of super large fire curtain clutch, and the multiple electric motors that solve a door frame roller shutter can not link, and can't realize that when only blowing a fuse roller shutter is from the technical problem of falling.
The technical scheme that its technical problem that solves the utility model adopts is:
This super large fire curtain clutch, comprise control cabinet, at least two motors and at least two fuses, it is characterized in that: each motor of same door frame fire curtain is parallel with one another, every motor is provided with a fuse, described fuse is a temperature sense glass tubular fuse, be not connected between each temperature sense glass tubular fuse and the motor, directly cross and be connected with the lead of battery, control circuit in the control cabinet is twinplex with each motor and is connected, wherein a circuit is connected with motor through the motor control device for pivoting, another circuit is connected with motor through braking control device, and the lead of battery is connected with braking control device through the joint of temperature sense glass tubular fuse.
Beneficial effect: the utility model takes the clutch of electric form to replace traditional mechanical fuse.A temperature sense glass tubular fuse is set at every motor place of same door frame fire curtain, is not connected between fuse and the motor, but directly be connected with the interior battery of fire curtain control cabinet.Control cabinet adopts twinplex when the control motor, a circuit control motor rotates, and another circuit control brake gear is opened, and battery then directly is connected with the circuit of control cabinet inner control brake gear; Control cabinet can be to charge in batteries when electricity was arranged, and battery can't be powered to control cabinet; In case the experience fire, the on-the-spot power failure is as long as certain fuse is blown, battery just begins power supply, and the circuit operate as normal of control cabinet control motor brake gear makes the multiple electric motors interlock, thereby realize falling certainly rapidly of fire curtain, can guarantee the secure closed fire compartmentation.
The utility model adopts temperature sense glass tubular fuse, replaces traditional mechanical type fuse, and warm sense ability is strong, is convenient to installation and maintenance and changes.
The utility model construction is simple, convenient maintenance and replacement, and construction cost is lower, the interlock problem when having solved the roller shutter outage of using multiple electric motors.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is a circuit connection diagram of the present utility model.
Reference numeral: 1-motor A, 2-motor B, 3-motor C, 4-temperature sense glass tubular fuse A, 5-temperature sense glass tubular fuse B, 6-temperature sense glass tubular fuse C, 7-fire curtain control cabinet, 8-battery, 9-motor control device for pivoting, 10-braking control device.
The specific embodiment
Embodiment is referring to shown in Figure 1, this super large fire curtain clutch, comprise control cabinet, at least two motors and at least two fuses, each motor of same door frame fire curtain is parallel with one another, every motor is provided with a fuse, described fuse is a temperature sense glass tubular fuse, be not connected between each temperature sense glass tubular fuse and the motor, directly cross and be connected with the lead of battery 8, control circuit in the control cabinet 7 is twinplex with each motor and is connected, wherein a circuit is connected with motor through motor control device for pivoting 9, another circuit is connected with motor through braking control device 10, and the lead of battery 8 is connected with braking control device 10 through the joint of temperature sense glass tubular fuse.
The course of work of the foregoing description: three motors are used in single door frame super large fire curtain configuration, temperature sense glass tubular fuse A correspondence is installed on the motor A, temperature sense glass tubular fuse B correspondence is installed on the motor B, temperature sense glass tubular fuse C correspondence is installed on the motor C, temperature sense glass tubular fuse A, temperature sense glass tubular fuse B, temperature sense glass tubular fuse C and motor A, motor B, motor C does not connect, but battery 8 direct and in the fire curtain control cabinet 7 is connected, the circuit that is connected with braking control device 10 in the fire curtain control cabinet is connected with battery 8, when electricity is arranged battery 8 is charged.When emergency power supply cuts off the power supply,, will make battery 8 begin power supply when burning disconnected any one fuse, control its braking control device of opening all motors simultaneously 10, three motor linkages, the cord of fire curtain can be finished decline according to deadweight rapidly, can guarantee the secure closed fire compartmentation.
