Abstract

The utility model relates to a fireproof electric vertical revolving door which is composed of a door leaf, a hinge, a door pivot and an electric door opener. The door leaf is connected with the upper end and the lower end of the door pivot through the hinge, foot wheels are arranged at the left top end and the right top end below the door leaf, and latch hooks are arranged at the left end and the right end of the lower door frame; mounting holes are formed at the two ends of the electric door opener, the mounting hole at one end is formed in the middle position of the vertical line of the door pivot, and the mounting hole at the other end is formed on the door leaf. The fireproof electric vertical revolving door has the advantages that the structure is simple, compact, safe and reliable. After the revolving door is installed, when a fire signal is sent from a fire protection control center, the door is controlled by a BAS system or a FAS system, and can be automatically closed, thereby separating the fire zone, and guaranteeing the protection to the life and the property of people.

Description

The fireproofing electric vertical rotary door

Technical field: the utility model relates to ventilation passage of metro fireproofing electric vertical rotary door.

Technical background: ventilation passage of metro fireproofing electric vertical rotary door is installed in the circuitous air channel between two tunnels of subway.Be positioned at end, station or tunnel, be in opening at ordinary times.Present ventilation passage of metro fireproofing electric vertical rotary door, complex structure is huge, not compact, safety is unreliable, difficulty is installed.Bringing hidden danger for people's life, property, is the important topic of this area scientific and technical personnel research.

Summary of the invention: the purpose of this utility model will provide a kind of fireproofing electric vertical rotary door exactly, it can overcome the present existing defective of ventilation passage of metro fireproofing electric vertical rotary door well, the purpose of this utility model is to realize like this, the fireproofing electric vertical rotary door is made up of door leaf, hinge, door-hinge, electric door-opening machine, it is characterized in that: described door leaf is connected in the upper/lower terminal of door-hinge by hinge, two tops are provided with the ground castor about the door leaf below, and two ends, the lower door frame left and right sides are provided with latch hook; Described electric door-opening machine two ends are provided with installing hole, and an end installing hole device is on the centre position of door-hinge vertical curve, and other end installing hole device is on door leaf.The utility model is simple in structure, compact, safe and reliable.After ventilation passage of metro is installed the utility model, when Fire Services Communication Centre sends fire alarm, close automatically by BAS system or the control of FAS system, form pyrotechnics distinguish every, guaranteed that people's lives and properties are protected.

Description of drawings: Fig. 1 is a circuitous air channel fireproofing electric vertical rotary door schematic diagram;

Fig. 2 is an electric door-opening machine;

1. hinge, 2. doorframe, 3. door leaf, 4. door lifter, 5. latch hook, 6. castor, 7. door-hinge 8. supports, 9. lower door frame, 401. installing holes, 402. motor, 403. gear reduction units, 404. screw mandrels, 405. shells, 406. pull bars, 407. installing holes.

The specific embodiment: the utility model is described in further detail below in conjunction with accompanying drawing;

In the drawings, the utility model fireproofing electric vertical rotary door is made up of door leaf 3, hinge 1, door-hinge 7, electric door-opening machine 4, it is characterized in that: described door leaf 3 is connected in the upper/lower terminal of door-hinge 7 by hinge 1, two tops are provided with ground castor 6 about door leaf 3 belows, and two ends, lower door frame 9 left and right sides are provided with latch hook 5; Described electric door-opening machine 4 two ends are provided with installing hole 401,407, one end installing holes 401 devices on the centre position of door-hinge 7 vertical curves, and other end installing hole 407 devices are on door leaf 3.During concrete enforcement, the specification design doorframe 2 that provides according to engineering design unit or construction engineering units; Door leaf 3 can be designed to single fan vertical hinged door, biparting clamshell doors or folding door, and door leaf 3 is connected in the upper/lower terminal of door-hinge 7 by hinge 1, and two tops are provided with ground castor 6 about door leaf 3 belows, not only door leaf 3 is played a supportive role, and it is light that door leaf 3 is opened and closed; Two ends, lower door frame 9 left and right sides are respectively arranged with latch hook 5, are convenient to door leaf 3 and close back locking, and the centre is provided with two supports 8 and guarantees that two door leafs 3 are indeformable after cutting out; On the centre position of door-hinge 7 vertical curves, installing hole 407 devices are on door leaf 3 with 401 devices of installing hole on the electric door-opening machine; When Fire Services Communication Centre sends fire alarm, behind the electronic vertical rotary door acknowledge(ment) signal, the axle of motor 402 turns clockwise, driven gear reducer 403 rotates, gear driven screw mandrel 404 in the gear reduction unit 403 rotates, be enclosed within pull bar 406 on the screw mandrel 404 by precession, drive door leaf 3 and be no more than 60S and close latch hook 5 lockings in the time rapidly.Under the normal condition, environment temperature≤45 ℃ under relative humidity≤95% condition, can make the long-term operation continuously of electronic vertical rotary door.Fireproof performance after electronic vertical rotary door is closed satisfies the requirement of first class labeled door fire integrity and fire insulation.AC220V is single-phase for the utility model rated operational voltage, and rated power is 1.5KW.And have on the spot and debug, control function; Simultaneously, have and BAS and FAS interface function; The utility model and latch hook by the power supply of two-way independent current source, are provided with dual-power automatic switching device and Presentation Function respectively in the electric control box.Like this, after fire signal is eliminated, the dual-power automatic switching device work in the electric control box, latch hook 5 is unclamped, motor 402 counterclockwise turns, the gear driven screw mandrel 404 in the gear reduction unit 403 rotates, screw mandrel 404 screws out pull bar 406 again, from and open door leaf 3 rapidly.
