Abstract
The invention relates to a fireproof electrical door opener, composed of an electric motor, a gear reducer, a screw mandrel, a case, a pull rod and installation holes. The case is provided with an inner cavity, the left top end is equipped with an installation hole; the electric motor is arranged on the left of the inner cavity of the case, a motor shaft is connected with the gear reducer, the gears of the gear reducer engages with the screw mandrel, the other end of the screw mandrel is sleeved with the pull rod provided with internal threads, the right end of the pull rod is provided with an insulation hole. The door opener has a simple and compact structure, and is safe and reliable. The door opener is installed on the fireproof electric vertical revolving door on the ventilating passage of a subway, when a fire-fighting control center sends a fire alarm signal, a BAS system or a FAS system controls the automatic close, a smoke and fire region is separated, thus ensuring the protection of people's life and property.
Description
Technical field:
The present invention relates to ventilation passage of metro fireproofing electric vertical rotary door, particularly relate to the fireproofing electric door-opening machine on the electronic 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:
Purpose of the present invention will provide a kind of fireproofing electric door-opening machine exactly, it can overcome the defective that present ventilation passage of metro fireproofing electric vertical rotary door exists well, the object of the present invention is achieved like this, a kind of fireproofing electric door-opening machine is made up of motor, gear reduction unit, screw mandrel, shell, pull bar, installing hole, it is characterized in that: described shell is provided with inner chamber, and left top is provided with installing hole; Motor is arranged on the shell inner cavity left side, and motor reel is connecting gear reduction unit, gear in the gear reduction unit and screw mandrel engagement, and the screw mandrel other end is with female pull bar is set, and the right-hand member of pull bar is provided with installing hole.The present invention is simple in structure, compact, safe and reliable.Be installed on the ventilation passage of metro fireproofing electric vertical rotary door, when Fire Services Communication Centre sends fire alarm, close automatically by the control of BAS system or 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 a structural representation of the present invention;
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 invention will be further described below in conjunction with accompanying drawing;
In the drawings, fireproofing electric door-opening machine of the present invention is made up of motor 402, gear reduction unit 403, screw mandrel 404, shell 405, pull bar 406, installing hole 407, and it is characterized in that: described shell 405 is provided with inner chamber, and left top is provided with installing hole 401; Motor 402 is arranged on the shell inner cavity left side, motor reel is connecting gear reduction unit 403, gear in the gear reduction unit 403 and screw mandrel 404 engagements, screw mandrel 404 other ends are with female pull bar 406 are set, and the right-hand member of pull bar 406 is provided with installing hole 407.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 curve directions, installing hole 407 devices are on door leaf 3 with 401 devices of the installing hole on the fireproofing electric door-opening machine; When Fire Services Communication Centre sends fire alarm, behind the electronic vertical rotary door acknowledge(ment) signal, the axle of the motor 402 in the fireproofing electric door-opening machine 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, fireproofing electric door-opening machine 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 fireproofing electric door-opening machine rated operational voltage, and rated power is 1.5KW.Fireproofing electric door-opening machine has on the spot debugs, controls function; Simultaneously, have and BAS and FAS interface function; Fireproofing electric door-opening machine 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, dual-power automatic switching device work in the electric control box, latch hook 5 is unclamped, motor 402 counterclockwise turns in the fireproofing electric door-opening machine, gear driven screw mandrel 404 in the gear reduction unit 403 rotates, and screw mandrel 404 screws out pull bar 406, from and open door leaf 3 rapidly.
