Description

Lifting device for stage equipment {The stage establishment ascent and descentt equipment}

The present invention is for raising and lowering stage equipment such as stage lighting and other facilities, and in detail, a plurality of thin plate-like thicknesses on the axis of the driving means driven by a motor, etc. The winding metal plate is provided with a winding drum which can be wound, and the winding metal plate is connected to a lifting frame to which lighting means or other facilities can be fixed, and a plurality of winding metal plates are respectively driven by the driving means. Guided along the guide roller, combined with the winding drum to be wound, so as to reduce the overall volume of the lifting device of the stage equipment, as well as the overall winding thickness of the plate-shaped winding metal plate in the winding state is Lifting device for stage equipment to ensure that the lifting speed of the lifting frame is applied uniformly Relate to.

In general, it is well known that a large amount of lighting is fixed near the stage ceiling in an indoor performance hall such as a theater or an auditorium or a concert to double the effect in a performance.

Such a stage lighting device is divided into a whole lighting device (usually called a flatlight) that causes the whole stage to be stepped on, and a local lighting device (spotlight) which continuously illuminates the stage. Has a structure of lifting up and down as needed through a separate lifting device.

In order to raise and lower the stage lighting device or other equipment of the stage as described above, such a stage equipment lifting structure is generally configured to be accommodated by utilizing the space on the stage and to be lowered or raised as needed. In order to elevate the devices, the wires are connected to the lifting frame formed in the longitudinal direction at equal intervals, and the wires are wound on the winding drum, and the wires are driven in the forward or reverse direction by the forward and reverse motors so that the wires When winding up, the lifting frame is lifted, and when the wire is released from the winding drum according to the reverse driving of the stationary motor, the structure is provided to be lowered by the weight of the stage apparatus.

However, such a lifting device is to stop the forward and reverse motor rotation at any position by the operation of the changeover switch to stop the lighting device, so in order to stop it at the correct position when lifting it up and down requires a little bit of skill, the stop position is slightly different It may cause unbalance of lighting equipment that needs to be balanced.In particular, when lighting equipment is lifted into the ceiling space, the lighting equipment is damaged by the phenomenon such as hitting the ceiling beyond the stopping position. Can cause problems.

In order to solve such a problem, Utility Model Publication No. 199595-6502, previously filed and registered with the Korean Intellectual Property Office, is disclosed. In the configuration of the cited example, the winding means is wound around the outer surface of the winding drum using a wire means, but the exact stop position is By the conduction plate configuration for determining the lifting frame reaches a certain height and when the outside the conduction plate is cut off the current flow to provide a configuration to stop the driving of the stationary motor, the lifting frame is stopped.

However, even in such a configuration, as the winding means of the lifting frame uses a wire having a predetermined thickness as in the prior art, the winding thickness becomes thicker while being wound with the winding drum due to the characteristics of the wire.

Thus, even if the drive rpm speed of the stationary motor is the same as the winding thickness is increased, the winding length is relatively long in one rotation of the winding drum, and thus the winding speed is increased, which is connected to the wire end. There is a problem that the lifting speed of the lifting frame fixedly equipped with the lighting means is to be gradually increased.

Therefore, when the lifting frame approaches the ceiling, the winding thickness of the wire wound on the winding drum achieves the maximum diameter, and the lifting speed of the lifting frame according to the increase in the winding speed of the wire relative to one rotation of the winding drum is also close to the maximum value. Therefore, the moment when the stationary motor stops, a sudden stop phenomenon of the rising and lowering speed causes considerable stress on the connection portion between the wire and the elevating frame, so that the connection portion between the wire and the elevating frame is broken during the repetition of such a phenomenon. In addition, there is a problem that a breakdown phenomenon may occur, such as a safety accident may occur during the stage performance.

Therefore, in order to solve such a problem, efforts have been made to minimize the diameter of the winding wire by maximizing the length of the winding drum, but the size and volume of the lifting device as a whole increases depending on the length of the winding drum. Of course, there is a problem that it becomes difficult to secure the installation space.

In addition, even if the winding drum is extended to a certain length, the diameter while being wound by the thickness of the wire must be increased, so that the lifting speed of the lifting frame can not be gradually overcome, and the point reaching the maximum rising point is maximum. It is pointed out that the above-mentioned breakage or breakage of the connection portion between the wire and the lifting frame due to the stress generated by the sudden stop of the stationary motor at the maximum lifting speed is inevitable.

Therefore, in some cases, the lifting device is often installed on the structure side of the stage rather than the stage ground in consideration of such a situation, but when the worker needs to lower the lifting device for the construction of the stage equipment or the lighting equipment, or the maintenance of the lifting device In case of requiring maintenance work, there is a problem that a safety accident due to the hassle and risk factors may occur, such as having to work on the structure of the stage equipment.

Therefore, the present invention has been devised to solve the above problems,

The stage equipment such as stage lighting or other stage facilities is fixed, and the ascending and descending speed of the elevating frame can be uniform, thereby minimizing the impact force generated when the elevating frame reaches the maximum raising or lowering position. Its purpose is to.

In addition, the present invention has an object to achieve a minimization and light weight of the installation area according to the minimization of the lifting device to raise and lower the lifting frame.

Therefore, the winding metal plate 200 guided to the main guide roller 21 is guided toward the respective branch guide rollers 12 in a state where a plurality of the winding metal plates 200 are overlapped.

As described above, one end of the winding metal plate 200 guided along the branch guide roller 12 is provided through a separate fixing hanger 21 provided on the upper surface of the lifting frame 20 spaced directly below the fixed structure 10. Each is fixedly connected.

A plurality of lighting means is fixed to the lower surface side of the lifting frame 20 spaced apart.

The elevating device 100 is configured to elevate the elevating frame 20 as described above, and the winding drum interlocked according to the driving of the stationary motor 110 and the stationary motor 110 fixed on the base 101. 130, the drum guide 140, and a plurality of guide rollers (150a ~ 150d) for guiding the other end of the winding metal plate 200, the fixing bracket 120 to be built up It should be provided.

That is, the driven shaft 170 is connected by using a separate flange coupling 160 on the drive shaft 111 of the stationary motor 110 fixed to one side end of the base 101.

The driven shaft 170 has a winding drum 130 and a drum guide 140 to be inserted and interlocked with the driven shaft 170 in the center as described above. The winding drum 130 is a drawing. As shown in the predetermined width, that is, to maintain the width of the winding metal plate 200 can be accommodated, the guide when the winding metal plate 200 is wound along the winding drum 130 to both sides of the winding drum (130) In order to ensure that the drum guide 140 is fixed.

In this case, connecting holes 134 and 142 are formed in order to fix the winding drum 130 and the drum guide 140, respectively, and the fixing holes 130 and 142 are fixed using separate pins P.

On the other hand, as the winding drum 130, as described above, a plurality of winding metal plates 200 are wound in one winding drum 130, in order to facilitate such an action, as shown in the drawing drum. (130) A plurality of cutouts 131 are formed along the outer circumferential surface, that is, as many as the number of the winding metal plates 200 in the inward oblique direction, and fixed holes in the horizontal direction on the axial center line at the end side of the cutout 131. A flat surface 131a having 132 is formed.

Therefore, the other end of the winding metal plate 200 having the flat surface 131a and is cut toward the cut-out portion 131 is fixed by a separate fixing means (for example, a bolt, etc.) by the fixing hole 132. Done.

As described above, since the plurality of winding metal plates 200 are fixedly connected to the fixing holes 132 of the respective cutouts 131, the plurality of winding metal plates 200 are divided into a plurality of portions along the circumferential surface of the winding drum 130 as shown in FIG. 4. To achieve the state that the winding metal plate 200 is connected to.

At this time, in order to maintain close adhesion along the outer circumferential surface of the winding drum 130 while the other ends of the respective winding metal plates 200 are fixed to the cutout 131 fixing holes 132, the winding metal plates ( 200) It is preferable to bend the portion leading to the outer peripheral surface side of the winding drum 130 from the other end, and to fix the fixing hole 132.

On the other hand, the fixed bracket 120 is provided with a plurality of guide roller shaft holes 122 for the purpose of laying out the guide rollers (150a ~ 150d) for guiding each of the plurality of winding metal plate 200 connected as described above The drum guide 140 is configured to have a structure that is fixedly installed from the upper surface of the base 101 in the outer side.

In the center of the fixing bracket 120, the above-described driven shaft 170 is arranged, but has a separate known bearing part 123 for a smooth rolling motion.

Here, reference numeral 300 denotes an encoder, and when the lifting frame 20 is moved up and down by the driving of the lifting device 100, the highest and lowest points of the top and bottom dead centers according to the lifting and lowering points, and It means well-known means for controlling the position control of the lowest point, the speed when raising and lowering, and the like.

That is, when the lifting frame 20 reaches a predetermined height or more when the lifting frame 20 is elevated according to the driving of the stationary motor 110, the lifting frame 20 is set to control the driving of the stationary motor 110. On the contrary, if the lifting frame 20 is lowered to reach a certain height, the driving control of the stationary motor 110 is controlled by setting each position control to recognize the position as the lowest dead center. In addition, it is preferable to set the setting so that the up and down speed of the elevating frame 20 can be operated at a relatively safe speed, so as to automatically control.

On the other hand, reference numeral 400 refers to a limit switch box, the power of the reference numeral 310 which may be composed of a belt or a chain for connecting the shaft between the pulley protruding from the limit switch box and the encoder 300 of the reference numeral 300. A transmission means.

Unlike the encoder 300 means capable of electronic control, the limit switch box 400 may be configured to control the up and down lifting position of the lifting frame 20 by mechanical operation.

Lifting device 100 having such a configuration can be fixed and provided at one end of the fixed structure 10 as shown in Figure 5, unlike the fixed to the stage ground side can be configured to install.

Hereinafter, an operation relationship using the lifting device 100 and the winding metal plate 200 having the above-described configuration will be described.

In the present operating relationship, the lifting device 100, which is an example of FIG. 5B, will be described with reference to the lifting frame 20 up and down relationship in a state where the lifting device 100 is located on the lower side, that is, the stage side.

In the state in which the elevating frame 20 having the luminaire 20 is positioned above the stage, the elevating frame 20 is lowered by reverse driving of the stationary motor 110 of the elevating apparatus 100 as necessary. If the replacement 30 or maintenance is required, the winding drum 130 interlocked with the stationary motor 110 is reversely rotated to release the winding metal plate 200 in the wound state. The metal plate 200 is guided along each of the guide rollers 150a to 150d arranged in a plurality of periphery of the fixing bracket 120, and the wound state is terminated.

That is, as the winding drum 130, four winding metal plates 200 in the drawing are coalesced and are wound together, and each winding metal plate 200 is the respective guide rollers 150a to 150d. In the guided state in each, it is to be released along the guide rollers (150a ~ 150d) at the time of reverse driving of the stationary motor (110).

As the lifting frame 20 is lowered by the winding-up metal plate 200 released as described above, the operator stops the operation of the stationary motor 110 when the reaching lower position is reached, and then the replacement or maintenance of the lighting means 30 is performed. Maintenance work can be performed.

On the other hand, if you want to raise the lifting frame 20 after the necessary work such as maintenance work or replacement is completed, winding the winding metal plate 200 in the unwinded state by driving the stationary motor 110 ( 130) It is wound along the outer circumferential surface.

That is, the winding hanger 21 and one end of each of the winding metal plate 200 of the lifting frame 20 through each of the branch guide rollers 12 of the fixed structure 10 is one side of the fixed structure 10 The guides are guided together at the main guide roller 13 side of the stage and branched to guide rollers 150a to 150d respectively arranged at the periphery of the fixing bracket 120 in the lifting device 100 at the lower side thereof.

Accordingly, each of the winding metal plates 200 connected to the upper surface fixed hanger 21 of the elevating frame 20 while being in the state branched from the branch guide rollers 12 of the fixed structure 10 are fixed. After joining in the overlapping state in the main guide roller 13 at one end of the structure 10, it is continued to the lower fixing bracket 120, each guide roller (150a ~ 150d) in the fixing bracket (120) After guiding again through branching, the laps along the outer circumferential surface of the winding drum 130 are combined and wound up.

As described above, the winding metal plate 200 wound by the winding drum 130 uses a stainless steel plate having a considerably thin thickness of about 0.5 mm, and thus the number of windings of the winding drum 130 is considerable. Even though the wound diameter as a whole, the amount of change in the increased diameter is considerably fine compared to the diameter of the winding drum 130, and the variation of the diameter is much smaller than the winding diameter due to the wire, and thus the lifting frame when the wire is lifted (20) When the) reaches the upper side, the lifting speed is increased to solve the problem completely.

That is, the difference in the ascending speed of the initial lifting frame 20 and the process of ascending and the speed when it is located on the uppermost side is the diameter of the winding drum 130 and the winding metal plate wound on the winding drum 130. Although it occurs due to the difference due to the diameter in the state in which the 200 overlaps, the maximum winding diameter on the lifting frame 20 position is completely wound up by the application of the winding metal plate 200 in the present invention is raised to the top Since there is no difference, since it does not deviate significantly from the initial speed, the constant speed lifting of the lifting frame 20 becomes possible.

This action, when considering that the diameter of the existing wire is usually 10 mm when compared to the diameter after the winding by the winding number of the winding metal plate 200 and the known wire in the present design, accordingly, the lifting Significant difference may occur in the speed variation, and when the speed variation of the elevating frame 20 uses a wire, the speed variation may increase rapidly, and the above-described problems may occur. This speed change is not greatly changed so that the lifting frame 20 can be raised at a speed close to the constant speed.

In the working example or the embodiment of the present invention, the lifting frame 20 for fixing the lighting equipment of the stage is mainly described and illustrated as an example, but the present invention is not limited thereto, and the stage for the screen or other various lifting and lowering. Applicable to facilities, etc., it is a matter of course that various designs and modifications can be made within the scope having the same technical idea.

Therefore, according to the present invention, the lifting means of the lifting device for lifting up and down the stage lights, other screens, various stage equipments, etc. is applied by winding the metal plate for winding by a metal material having a relatively thin and rigid, By providing a minimized change in the diameter of the ear wound wound on the winding drum outer circumferential surface according to the positional shift due to the vertical lift of the elevating frame can be expected to the effect of making the elevating and descending speed of the elevating frame uniform.

In addition, the present invention can minimize the size of the winding drum and the size of the overall lifting device by applying a winding metal plate, which is considerably thin, so that the effect of minimizing the installation area and weight can be expected. It is a useful design.
