The present invention relates to a drive device for an automatic fire door, and more specifically, in an automatic fire door used for an elevator fire door or a front fire door of a building entrance, the opening and closing of both fire doors is asymmetric using a friction clutch action based on a magnetic force of a roller. The present invention relates to a drive device for an automatic fire door that can be performed as well.

In general, automatic fire doors, which are used as elevator fire doors or front fire doors of an elevator, are mostly tied to a timing belt or V-belt that is reciprocally rotated for a certain section by the force of a geared motor, so that one side or It is configured to open and close to both left and right sides.

At this time, by installing the rollers on both sides of the upper side of the fire door, the fire door is slid more smoothly in a state where the fire door is suspended on the guide rail, and by installing a stone piece at the bottom of the fire door, the stone piece is a groove of the threshold Since the door is moved, the fire door is configured to reciprocate without swinging.

In other words, as shown in FIG. 1, one embodiment of the fire door drive device 40 in the conventional automatic fire door as described above will be described. Drive pulleys 41 are respectively provided on both upper sides of the door frame frame 10. ) And the driven pulley 42, the timing belt or V-belt 43 connecting the driving pulley 41 and the driven pulley 42, and the timing belt or V by transmitting power to the driving pulley 41. A drive motor 44 for imparting a moving force to the belt 43, a guide rail 45 provided to be parallel to the timing belt or the V-belt 43 on the lower side of the door frame frame 10, and timing The left fire door hanger bra is fixed to both sides of the lower part of the belt or V-belt 43, and the left fire door 20 is suspended under the guide rail 45 along with the main fire door 20, and is linearly reciprocated. And kets 46 and 46 '. Here, the right fire door 30 is suspended on both lower sides of the timing belt or the V-belt 43 by a right fire door hanger bracket (not shown).

However, for example, in the state in which the right fire door 30 is closed and fixed to the right side, the left fire door 20 moving in conjunction with movement to the transmission member such as the timing belt or chain is displaced from the right fire door 30, or the like. Due to various problems, the close contact force between the door frame frame 10 and the fire doors 20 and 30 is reduced, so that in case of a fire, there is a risk of leakage of flame salts when the temperature rises to 1250 degrees Celsius. The disadvantage was that no countermeasures were prepared. Moreover, there was concern that it would not be possible to block the smoke inside the fired facility.

Therefore, the present invention is made to solve the above problems, an object of the present invention, in the automatic fire door used in the elevator fire door or the front fire door of the building entrance, it is possible to smoothly perform the opening and closing operation of the fire door, in particular the slide door side.

Due to the above configuration, a sliding fire door that can be opened and closed, and a fire door driving mechanism for operating the fire door is achieved.

In addition, in the drawing, the fire door drive mechanism is provided on each of the upper sides of the door frame frame 10, the reduction gear 160 having pinion gears to receive the driving force from the drive motor (M) via a known gear train. The focus is on maintaining the airtightness when closing the slide door 120 is moved in conjunction with the transmission member such as a chain that is moved in accordance with the gear ratio.

Here, the slide door 120 is slidably installed in the door frame frame 10 of the upper, left and right ends and the bottom partitioned along the inner periphery of the opening of the building wall, the upper door frame frame 10 is In addition, the front face is partially opened so as to mount and detach the microcomputer and the fire door driving mechanism for operating the plurality of slide doors.

In addition, since the height of the threshold and the guide rail of the fire door is set by the frame of the building or the fire door, respectively, when the height of the threshold and the guide rail of the fire door at the time of construction is determined, the size of the fire door is determined accordingly. After the roller slider is coupled to the upper surface of the fire door, the slider is mounted on the upper guide rail to mount the slide door 120 to be slidable.

In addition, the slide door 120 is suspended on the upper side of the door frame frame via the guide rail, and at the same time through a drive mechanism inside the upper inner wall portion of the door frame frame 10 is partially open, Sliding movement is possible.

In the fireproof automatic door driving system disclosed above, a driven pulley in which a chain for driving the automatic door and the like are engaged with the surrounding, and a deceleration gear 160 capable of reverse rotation, are installed and can be opened and closed emergencyly.

The present invention intends to consider the above-described situation, and an object of the present invention is to allow the automatic door to be electrically opened and closed in case of an emergency or a daily power interruption such as a fire occurrence or an accompanying power interruption. The opening and closing of the automatic door can be controlled according to a predetermined program.

In order to achieve such an operation, the present invention is connected to the automatic door controller for controlling the automatic door driving motor (M), the AC power and the battery power is connected through the emergency storage device, and also by the function of the automatic door controller, While the power from the AC power is normally applied to the automatic door controller by operation, the power supply of the automatic door controller is suppressed from the battery power and the battery power is charged from the AC power. It is switched to supply power to the controller so that the automatic door can be operated or stopped in the event of power interruption by the function of the automatic door controller. Made according to a predetermined program by To make, and is provided an automatic fire door drive system, an emergency signal and a power shut-down signal which is output to the automatic door controller.

In addition, in setting the height position of the slide door, the upper guide rail 230 is crosslinked to the door frame frame 10 in a direction crossing it.

At this time, the first and second sliders 210 and 220 coupled to the slide door 120 are mounted on the installed upper guide rail 230, and then the clamping member 300 is mounted on the transmission member 130 at a set position. ) Is coupled to the first or second sliders 210 and 220.

Next, to describe the driving force transmission process to the slide door 120, when power is applied to the drive motor (M) under the control of the control unit, the driving sprocket (150) on the rotating shaft of the reduction gear of the motor (M) By transmitting the motor driving force to the sliders 210 and 220 through the wound transmission member 130, forward and backward driving for opening and closing of the slide door 120 is achieved.

In addition, driving along the curve of the first driving roller 211 corresponding to the first curved portion 231 of the upper guide rail 230 and the fifth rolling roller 290 corresponding to the second curved portion 281. ), The traveling of the third rolling roller 250 corresponding to the third curved portion 241, and the rearward pressing movement of the fourth rolling roller 270 corresponding to the cam block 260 In an organic connection, more confidentiality is guaranteed.

Of course, the controller determines the opening / closing position in response to the known sliding door 120 opening / closing position detecting sensor, sends the control section to the controller, and instructs the driving of any one of the forward and reverse driving of the motor M to start.

As described above, according to the present invention, the setting force for the slide door pressurizing operation is transmitted to the slide door while the slide door is pressurized based on the driving of the individual drive rollers that are guided and moved in correspondence with the first to third curved portions. By doing so, a confidential fire door is obtained.

The technical idea of the fire door of the present invention has been described with reference to one embodiment shown in the accompanying drawings, but this is merely exemplary, and those having ordinary knowledge in the art may various modifications and equivalents therefrom. It should be understood that other embodiments are possible.
