Description

Safety device for stage facilities to control wire rope tension and prevent separation {SAFE LIFTING AND LOWERING DEVICE FOR STAGE EQUIPMENT}

The present invention relates to a safety device for stage facilities, and more particularly, a safety device installed 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 bar turn and a curtain, It relates to a safety device for stage facilities that controls the tension of the wire rope and prevents it from leaving.

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.

6 is a detailed configuration diagram of a stage device button according to another embodiment of the present invention, FIGS. 7 to 9 are views for explaining a tension control device according to another embodiment of the present invention, and FIG. 10 is another embodiment of the present invention. It is a diagram illustrating an example of a combination of a vertical pulley and a stage device bar according to an example.

Referring to the drawings, the stage device button 30 according to another embodiment of the present invention includes a tension control device 320 that adjusts the tension of the wire rope (L) of the vertical pulley 20 in the longitudinal direction of the stage device button. A tension bar 330 for fixing the bar turn is provided on one side of the tension control device 320 so that the stage device bar 30 is fixed to the magnetic bar 210 provided on one side of the vertical pulley 20 Make up.

Referring to the drawing illustrating an example of a combination of a vertical pulley and a stage device button according to another embodiment of the present invention of FIG. 10, a wire rope (L) at one end of the tension control device 320 inserted into the stage device button 30 ) Is connected, and it can be seen that a tension bar 330 for fixing the bar turn is provided on one side.

The tension control device 320 is provided with as many as the number of vertical pulleys, and is configured to adjust the length of the wire rope (L) by connecting the wire rope (L) connected to each vertical pulley to one end.

Referring to the detailed configuration diagram of the tension control device in an embodiment of the present invention of Figures 7 to 9, the tension control device 320 is provided on one side of the stage device button 30 to guide the wire rope (L), and The turn roller 321 that changes the tension direction of the wire rope and the stage device bar turn 30 are inserted inside, the wire rope L passing through the turn roller 321 is fixed at one end, and a thread is formed on the outer circumferential surface. The pipe 323 and the screw thread formed on the inner circumferential surface comprise a rotation control ring 324 screwed with a screw thread formed on the outer circumferential surface of the rotation pipe 323, and the rotation pipe screwed to the fixed rotation adjustment ring 324 By rotating the 323 clockwise or counterclockwise, the wire rope (L) coupled to one end of the rotating pipe 323 moves to the left and right, so that the tension of the wire rope (L) can be adjusted.

That is, in order to move the wire rope (L) coupled to one end of the rotation pipe 323 by the rotation of the rotation pipe 323 within the rotation control ring 324, the rotation control ring 324 is a stage device button. The rotation pipe 323 fixed to 30 and screwed to the thread of the rotation adjustment ring 324 is to be moved left and right.

Specifically, the rotation control ring 324 is integrally configured with the stage device bar 30 at the corresponding position as many as the number of vertical pulleys 20, and the rotation pipe 323 is fixed through the fixed rotation control ring 324. It is to rotate to move left and right.

Referring to FIG. 7, the rotation adjustment ring 324 has an adjustment window 324a, and a part of the rotation pipe 323 screwed with the internal thread of the rotation adjustment ring 324 is through the adjustment window 324a. It is configured to be exposed so that the rotating pipe 323 is adjusted from the outside through tweezers or a drive.

The rotation pipe 323 forms a ring part 322 that rotates at one end for easy adjustment, and a wire rope (L) is fixed to the ring part 322, and its longitudinal section is a round arc ( 323b) and the threadless plane 323a are alternately configured but are formed to be repeated three or more times.

Referring to FIG. 8, it can be seen that the planes 323a without threads are formed at intervals of 120°.

In addition, the tension control device 320 according to another embodiment of the present invention is not often used, so that the wire rope (L) is usually firmly supported by the stage device button 30, and if necessary, the tension control device ( Since it is to adjust the wire rope (L) little by little by using the 320, there is no need to increase the control window (324a) on the rotation control ring (324).

In addition, when the adjustment window is formed long along the arc of the rotating pipe 323, the tension adjustment device can be easily adjusted, but there is a possibility that the rigidity of the stage device button 30 is weakened due to this.

Therefore, since the adjustment window 324a should be able to easily adjust the rotation pipe 323 within a range that does not impair the rigidity of the stage device button 30, approximately the adjustment window 324a is along the outer peripheral surface of the rotation adjustment ring 324 It is preferable to configure it with 1/3 or more and 1/2 or less of the entire outer peripheral surface.

Referring to FIG. 9, it can be seen that a flat surface 323a without a thread is seen through the adjustment window 324a through the round arc 323b in which the thread of the rotation pipe 323 is formed.

Therefore, when adjustment is required, when pressing the plane 323a through the control window 324a to rotate using tweezers or a driver, the wire rope L moves to the left and right based on the rotation control ring 324.

In other words, for easy adjustment of the rotating pipe 323, a round arc formed on the outer circumferential surface with a screw thread on its longitudinal section and a plane without a thread are alternately formed, but are formed to be repeated three or more times to open the stage device button 30 When the flat portion of the rotating pipe 323 is pressed through the hole and rotated in a clockwise or counterclockwise direction, the length of the wire rope L is adjusted left and right.

The structure of the stepped jaw is only a means for binding the upper body and the lower body with a simple configuration, and the present invention is not limited thereto, and a configuration in which the upper and lower bodies can flow without being separated from each other is sufficient.

Referring to the drawing, the spring 332 is inserted into the hollow portion of the upper body 333 and the lower body 331, and the first stepped jaw 333a of the upper body 333 is lowered by the restoring force of the spring 332. It is configured to be inserted into the second step 331a of the body 331 so as to flow up and down.

The upper and lower flow width may be as large as the height (y) of the stepped jaws and the floor of the maximum lower body, but it will be shorter than y when considering the compressed length of the spring.

Giving such an up-and-down fluidity responds flexibly to external influences rather than being fixed with a fixed bar, and also, the tension bar 330 for fixing the bar turn is moved and fixed by the rotation of the wire rope (L). If the length of the wire rope (L) is not the same, the stage device bar turn 30 may not be stored horizontally, but if the tension bar 330 for fixing the bar turn flows up and down as in the present invention, the wire rope (L) Even if it is partially short or long, the stage device button 30 can be kept horizontally.

In addition, in the present invention, it has been described that the tension bar 330 for fixing the bar turn installed on the stage device bar 30 is flowed, but the magnetic bar 210 provided in the vertical pulley may be made to flow at a certain height up and down, or reverse. Of course, it can also be configured as.

Therefore, if the grid iron is configured in a plate shape, the hole through which the wire rope (L) passes near the support bracket 220 supporting each vertical pulley 20 and one end of the tension bar 320 for fixing the magnetic bar 210 and the bar turn It is natural that a hole for additional coupling should be formed.

In addition, the driving unit 40 is installed above the grid iron 10, a driving motor 440 that generates a rotational force, and a winding connected to the driving motor 440 to wind or wind a wire rope (L). Among the stage facilities consisting of a driving unit 40 composed of a drum 430, it is installed on one side adjacent to the driving unit 40 to constitute a driving motor 41.

That is, the driving unit 40 is operated to lift or lower the stage device bar 30 by winding or rewinding the wire rope L, and is installed above the grid iron 10, and a driving motor that generates rotational force A wire rope (L) configured to include a winding drum 430 for winding or winding a wire rope (L) rotated to the drive motor 440, and wound or rewinded to the winding drum 430 It includes a wire rope tension roller 410 that automatically adjusts the height of the coil so that it is wound on the winding drum more easily.

Referring to the detailed configuration diagram of the stage device driving unit according to an embodiment of the present invention of FIG. 14, the driving unit 40 includes a wide drum cover 420 installed above the grid iron 10, and a wide drum cover 420. The driving motor 440 provided on one side of the winding drum 430, which is installed inside the wide drum cover 420, is rotated connected to the driving motor 440 to wind or wound the wire rope (L), and the winding Wire rope tension roller 410 supplied by adjusting the height of the wire rope (L) supplied to the winding drum according to the height of the wire rope (L) that is wound or unwound on the winding drum according to winding or rewinding of the drum 430 Is illustrated.

In the winding drum 430, the positions of the wire ropes L supplied from the pulley rotator 240 of the vertical pulley 20 differ from each other according to the amount of the wire rope L to be wound or rewinded.

That is, referring to FIG. 14, according to the amount of the wire rope L wound or re-wound on the winding drum 430, a difference in the amount of the wire rope L wound by the height of “x” occurs.

This difference will be affected by the weight of the lighting device or the film coupled to the stage device bar turn 30, but a considerable load is applied to the wire rope (L), and eventually the load is applied to the winding drum 430 and thus the winding drum The possibility that the wire rope (L) wound around the 430 is separated is very high.

At this time, if the rope wound by the angle "x" has an inclination angle, much more load is applied and the possibility that the wire rope (L) wound around the winding drum 430 will deviate is even higher, and eventually the stage setting button 30 There is a consequence that further increases the risk of falling.

Therefore, in the present invention, the wire rope tension roller 410 is installed as many as the number of vertical pulleys 20 so that the wire rope L wound or rewinded in the vertical pulley 20 can be stably wound on the winding drum 430 To guide.

Specifically, the tension roller 410 allows the tension roller 410 to flow up and down by the tension of the wire rope, and the wire rope flowing up and down by the tension roller 410 is wound almost horizontally around the winding drum 430 It is to be.

That is, the tension roller 410 prevents the wire rope L from being separated and maintains the tension while flowing up and down according to the tension of the wire rope L between the heights of x1 to x2.

In the above, the present invention has been described in detail with respect to the described embodiments, but it is obvious to those skilled in the art that various modifications and modifications are possible within the scope of the technical idea of the present invention, and it is natural that such modifications and modifications belong to the appended claims.
