CONSTITUTION: The driving device is comprised of:a clutch(3) for driving and separating a motor(2) which supplies power for moving a fire prevention screen up and down; an urgent driving unit(5) for separating the action of the clutch and the motor; a shock absorber(6) for performing a buffing operation by freely dropping the fire prevention screen. Herein, the urgent driving unit(5) is consisted of a first bob(5-1), a fixing pin(5-5), and a second bob(5-2) for that the clutch is operated for the separation of the motor action by the displacement of the fixing pin.

Description

Drive device of fire protection wall for stage}

The present invention relates to an apparatus for driving a stage fire protection device, wherein the operation of the fire protection film is carried out by a clutch operation by the operation of a pull pin in case of a power failure to cut off the power of the motor, and the stage fire protection device configured to lower the fire film by the motor during an uninterruption. Relates to a device.

In general, a fire screen is installed on the stage to prevent fire by preventing the movement of flames from the stage device to the stage when arson. In this case, the operation of the fire screen uses a motor, but in the case of fire, electricity is mainly cut off, and therefore, it is difficult to suppress the suppression.

The present invention is to solve this, an object of the present invention is to provide a stage fire screen driving apparatus for manually operating a fire screen in the case of a fire, and to lower the fire screen using a motor in the event of a power failure even in the usual or fire. will be.

To this end, the present invention is provided with a clutch for transmitting and blocking the driving force of the motor to lower the fire film, the clutch is configured to block the power transmission of the motor in conjunction with the pull of the pull pin, the fire film is shock absorbed by the shock absorber Configure to degrade.

That is, the present invention is a clutch for driving and separating the operation of the motor to provide power to move the fire screen up and down;

An emergency drive unit that functions to disengage the motor from the clutch in conjunction with the release of the ground pull pin;

A shock absorber configured to freely fall and cushion the fire screen frame according to the clutch detachment operation;

The emergency drive unit has a first weight which is lowered by the release of the pulling pin, a fixing pin which is released in conjunction with the lowering of the first weight, and a second function of the clutch to separate the motor operation by the release of the fixing pin. It is an object of the present invention to provide a stage fire screen driving apparatus comprising a weight.

Hereinafter, the present invention will be described in detail with reference to the drawings.

FIG. 1 is a configuration diagram of the present invention, and FIG. 2 is a configuration diagram of the emergency drive unit of the present invention, and a clutch 3 for driving and separating an operation of a motor 2 that provides power for moving the fire screen 1 up and down. ,

An emergency drive unit 5 which functions to disengage the operation of the motor 2 by the clutch 3 in conjunction with the release of the pull pin 4 installed at the bottom;

A shock absorber (6) which freely falls and buffers the fire protection film (1) in accordance with the clutch (3) separating operation;

The emergency drive unit 5 has a first pin (5-1) that is lowered by the release of the pulling pin (4) and the fixing pin (5) is released in conjunction with the lowering of the first weight (5-1). 5) and the second weight 5-2 which functions to allow the clutch 3 to be separated from the motor operation by detachment of the fixing pins 5-5. Meanwhile, the release of the force driving the emergency drive unit 5 by pulling the pull pin 4 is configured to be made by the fuse link 7. Preferably, the fuse link 7 may be configured to break at about 70 degrees. The fixing pins 5-5 constituting the emergency drive unit 5 are fixed to the fixing pin support frame 5-3 so as to be detachable, and the fixing pins 5-5 attach the second weight 5-2. The supporting second weight support bar 5-4 is also detachably fitted.

In the above, the shock absorber 6 is connected to the rope 8, the weight body 6-1 fixed to the lowered position through the support rollers (9, 9-1), the weight body 6-1 and the shock absorber The extension rope 6-3 which connects the cylinder rod 6-2 of (6) and the extension rope 6-3 are guided to the tip of the cylinder rod 6-2 to guide the extension rope 6-3. It comprises a roller (6-4) made to guide the).

The present invention configured as described above usually functions to operate the fire protection film as necessary by driving the motor 2 to raise and lower the fire protection film 1. In this state, if a fire occurs but there is no power failure, the function of the motor is the same as that of the general motor, and thus the description thereof is omitted. In addition, a description of the power supply and switch configuration and operation to enable the driving of the motor is omitted.

Meanwhile, if there is a power failure with fire, anyone pulls out the pulling pin (4). Then, the first weight 5-1 constituting the emergency drive unit 5 is lowered as shown in FIG. 2. Then, the fixing pin 5-5 fixed to the first weight 5-1 moves in conjunction with the lowering of the first weight 5-1 to the left. Thereby, since the 2nd weight support bar 5-4 of the 2nd weight 5-2 deviates from the fixing pin 5-5, the 2nd weight 5-2 falls free. At the same time as the second weight 5-2 free-falls, the lever of the clutch 3 rotates to disconnect the connection with the motor 2 so that the fire protection film 1 free-falls. At this time, a shock absorber (6) is installed at the opposite end of the rope (8) for lowering the fire protection film (1), thereby preventing the fire protection film from descending rapidly when the fire protection film (1) descends. Prevents injuries

The present invention described above is not limited to the above-described embodiments and drawings, and various permutations, modifications, and changes can be made without departing from the technical spirit of the present invention. It will be apparent to those who have

As described above, the present invention pulls a pull pin during a power outage due to a fire, so that the emergency driving unit is driven, and the operation of the shock absorber during operation of the emergency driving unit prevents a complete free fall to prevent injuries of the person in the lower position of the fire screen. If a power failure does not occur even in a fire, use a motor to decelerate and rotate so that the fire screen is slowly lowered so that the fire screen automatically operates.
