SAFE LIFTING AND LOWERING DEVICE FOR STAGE EQUIPMENT WITH INDUCTION DEVICE}

The present invention relates to a safety device for stage facilities, and more particularly, by installing a safety device in a stage facility that moves up and down through winding and unwinding of a wire rope in a winding drum and a vertical pulley, such as a stage device button and a curtain, It relates to a safety elevating device for stage facilities equipped with a guide guidance device capable of preventing a fall of a stage facility due to a malfunction in advance and minimizing the shaking of a bar turn.

In general, a variety of devices are installed on the stage, such as lighting equipment that illuminates the stage as well as effect equipment that creates an effect necessary for the performance content, and a curtain lift mechanism that variably compartments the stage with the audience.

These devices are usually mounted on an elevating stage facility for management, maintenance, and performance production, and are installed so that they can be elevated up and down.

1 is a schematic diagram showing the state of a conventional elevator stage facility.

Referring to the drawings, a conventional stage facility is a facility for lifting and moving the stage device button 30, and a horizontal wall or a grid iron 10 is connected by a hanger in order to provide a predetermined space on the ceiling (W). .

Here, in the grid iron 10, a plurality of vertical pulleys 12 having a guide sprocket 11 having a hinge structure thereon are installed, and a guide wheel 21 is hinged at one end of the vertical pulley 12. The guide pulley 20 is installed so as to be installed.

At this time, the guide wheel 21 is made of the same number as the number of the pulleys 12, and each pulley 12 is installed to achieve a different positional relationship when viewed from the top.

On the other hand, a driving unit 40, which is a driving source of an elevating stage facility, is installed on the ground of the stage to elevate devices such as lighting lamps or membranes that variably compartmentalize the stage and audience.

At this time, the driving unit 40 is provided with a driving motor 41 that generates rotational force, and a winding drum 43 that is connected to the driving motor 41 through a belt and receives the rotational force of the driving motor 41 to rotate.

Accordingly, a spiral groove for guiding the winding operation of the wire rope L is formed on the outer peripheral surface of the winding drum 43.

In addition, a plurality of wire ropes (L) are connected to the stage device button (30), and each wire rope (L) is each guide sprocket 11 of the pulley 12 and each guide wheel 21 of the guide pulley 20 ) Through the winding drum 43 of the driving unit 40 is wound and wound.

Accordingly, when the wire rope (L) is wound on the winding drum 43 through the rotational force of the driving motor 41, the stage device button 30 rises by pulling the wire rope (L), and the winding drum 43 When the wire rope (L) is recommended, the stage setting button 30 descends.

However, such a conventional stage facility has a problem in that the stage facility falls to the stage during the ascending or descending operation of the stage facility, which is a heavy object, resulting in many human accidents.

That is, when a malfunction occurs due to an overload of the driving motor, the installation frame falls without any restrictions because a safety device for controlling the winding and unwinding of the wire rope in the winding drum is not provided.

In addition, there is a problem in that the wire rope is separated from the guide wheel in the process of being wound on the winding drum, causing a malfunction of the stage facility.

That is, in the process of winding a plurality of wire ropes intensively connected by a guide wheel to the winding drum, the guide wheel only rotates at the same position, but the wire rope wound on the winding drum moves along the helical direction so that the wire rope is oblique. Because it bends in the direction.

In addition, the stage device button 30 is connected to a plurality of wire ropes (L) to maintain the level. However, the length between the wire ropes is changed due to long use, so that the horizontal adjustment is required. Since it is connected vertically to (L), it is very inconvenient to adjust the length.

And since the stage device bar 30 is simply fixed and stored on the pulley installed at the top after use by the tension of the wire rope (L), there may be a risk of shaking or falling even if there is a small change in the external environment.
