It is a drawing to explain the pressurizing frame in the drive unit of the stage equipment brake capable of load control according to an example, and Figure 10 shows the entire stage equipment including the stage equipment brake capable of load control according to an embodiment of the present invention. This is a drawing for explanation.

As shown in Figure 1, the brake 10 for stage equipment capable of controlling the load of the present invention is a brake for limiting the movement of a wire formed long in one direction, and largely consists of a main body unit 100, a limiting unit 200, It may include a driving unit 300.

Specifically, as shown in FIG. 2, the main body unit 100 has a wire inserted into a limiting unit 200, which will be described later, and the limiting unit 200 is operated by a driving unit 300, which will be described later, so that the wire moves. It can be provided in a form that is stably fixed to one side so that it can be limited.

At this time, a space is formed inside the main body unit 100 to provide a driving unit 300, and the driving unit 300 can be connected to the limiting unit 200 fixed to the main body unit 100.

In addition, as shown in the drawing, the main body unit 100 has at least one long hole formed on the lower seating surface, so that the fixed position on one surface can be adjusted.

At this time, the lower seating surface may be coupled to the main unit 100 in a form different from the drawing, but may be arranged to be positioned by moving coordinates from a preset reference point through electrical control.

In addition, although the lower seating surface of the main unit 100 is not shown in the drawing, an absorbing member may be further provided to absorb vibration and shock.

Here, the main body unit 100 may be assembled to replace the drive unit 300 provided in the internal space.

In addition, the main body unit 100 may have at least one maintenance hole penetrating from the outside to the inside for maintenance of the drive unit 300 provided in the interior space without disassembling the entire assembly.

For example, maintenance holes may be provided in a symmetrical form on a pair of surfaces facing each other on the main unit 100.

In addition, even if the maintenance hole is provided to be opened and closed on the main unit 100, it will be said to fall within the scope of the present invention.

The restriction unit 200 has at least one pad 240 in contact with the wire to restrict the movement of the wire, and is provided to be spaced apart from the wire to release the restriction on the movement of the wire.

Next, the drive unit 300 may pull at least one pad 240 of the above-described pads 240 that is spaced apart from the main body unit 100 to the main body unit 100 and bring it into close contact with the wire.

Here, if the movement of the wire can be restricted or the movement restriction can be lifted, the shape, location, and number of the pads 240 are not limited and can be changed in various ways.

However, for more detailed explanation, as an example, as shown in FIG. 3, the pad 240 of the limiting unit 200 may include a lower plate member 210 and an upper plate member 220.

As presupposed at this time, even if the upper plate member 220 and the lower plate member 210 are divided again or the angle is changed in some cases, it is natural that they all fall within the scope of the present invention.

For example, the lower plate member 210 may be fixed to the main body unit 100 and a wire may be placed on its top.

At this time, the upper plate member 220 has a wire disposed below it, and is in close contact with the lower plate member 210 described above at the first position, and may be spaced apart from the lower plate member 210 at a preset interval at the second position, which will be described later. It can be operated by the driving unit 300.

In addition, one side of the upper plate member 220 and the lower plate member 210 is connected to the vertical guide 230 perpendicular to one side of the lower plate member 210, so that the upper plate member 220 and the lower plate member 210 are connected to the vertical guide 230. may be spaced apart or in contact in the longitudinal direction.

The operation of the driving unit 300 will be described later, and the structure and shape of the pad 240 of the limiting unit 200 will be examined in detail as follows.

As shown in FIG. 3 described above, the pad 240 of the limiting unit 200 may be provided to contact wires arranged in a direction perpendicular to the longitudinal direction at a preset interval.

In other words, the pad 240 of the limiting unit 200 can be provided with a groove 242 so that it can contact a plurality of wires simultaneously and hold all the wires at once.

For example, the pad 240 described above may be provided in a form in which a non-contact section provided in a planar shape and a contact section with a curvature are repeatedly formed along the wire arrangement direction.

This form of the pad 240 may be provided on at least one of the lower plate member 210 and the upper plate member 220 described above.

Although not shown in the drawing, the contact section of the pad 240 may have a curvature corresponding to the size of the wire, and protrusions may be formed on the inner peripheral surface of the curved surface or the inner peripheral surface of the curved surface may be coated with a material to improve friction.

For example, a resistance layer having a preset thickness may be further formed on at least one pad 240 of the lower plate member 210 and the upper plate member 220.

Here, the resistance layer can be applied to the lower plate member 210 and the upper plate member 220 at a uniform thickness, and is applied at different thicknesses to the surface of the lower plate member 210 or the upper plate member 220 divided into at least two regions. You can also do it.

Here, the composition of the resistance layer may include at least one of urethane resin, nitrile-butadiene rubber (NBR), chlorosulfonated ethylene rubber, and chlorinated ethylene rubber to increase the coefficient of friction.

To further increase the frictional force, at least one of natural silica sand powder, porous aluminum oxide, copper powder, and carbon nanotube powder may be added to the resistance layer.

Furthermore, the non-contact section and the contact section with curvature described above may be provided in the form of a plurality of unit members with different dimensions and shapes, and may be selected according to the distance between wires or the diameter of the wire.

Regarding the drive unit 300 that pulls at least one pad 240 spaced apart from the main unit 100 among the pads 240 described above with reference to FIGS. 4 to 9 to the main unit 100 and brings it into close contact with the wire. A more detailed explanation is as follows.

Referring to FIG. 4, the driving unit 300 may specifically include a moving frame 322 and a connecting frame 324.

The moving frame 322 is connected to the lower plate member 210 and may be provided to move from a first point to a second point along the guide slit 310 formed in the main body unit 100.

At this time, the connection frame 324 has a structure that rotates around the moving frame 322 and the lower plate member 210 so that the lower plate member 210 can be moved from the first position to the second position according to the movement of the moving frame 322. It can be connected to .

At this time, the driving unit 300 may further include a fixed frame. The fixed frame may be fixed to the main unit 100 so that the moving frame 322 can be fixed at the second point.

For example, the fixed frame may be provided so that one side can be rotated on the inner upper surface of the main unit 100.

At this time, the fixing frame may be formed long toward the inner lower surface of the main unit 100, and a fitting groove 242 may be formed therebetween.

Here, the position and shape of the fitting groove 242 can be changed into various forms in response to the movement and shape of the moving frame 322 described above.

If the movable frame 322 is provided in a cylindrical shape so as to move smoothly in the guide slit 310 formed in the main unit 100, the fitting groove 242 of the fixed frame may also be provided in a curved shape.

As the lower plate member 210 is fixed in the second position, the upper plate member 220 and the lower plate member 210 of the pad 240 are spaced apart in the limiting unit 200, and the spaced upper plate member 220 and the lower plate member ( 210), a wire is placed between them to maintain a standby state.

The driving unit 300 having the above-described configuration may further include a restoration frame 326.

When the moving frame 322 is released from the fixed frame, the restoration frame 326 quickly moves the moving frame 322 so that the upper plate member 220 and the lower plate member 210 come into close contact with the wire to limit the movement of the wire. It can be returned to point 1.

At this time, the structure in which the restoration frame 326 is connected to the moving frame 322 may vary. For example, as shown in FIG. 9, it may be arranged in plural numbers to restore the moving frames 322 at the same time. Although not shown in the drawing, in some cases, one restoration frame 326 may be used as one moving frame. It may be changed to a form that restores (322).

In other words, the restoration frame 326 can be rotatably coupled to one side of the main unit 100 and the moving frame 322 so that the moving frame 322 moving in the direction of the second point can elastically return to the first point. .

To summarize, in the above-described standby state, when the electromagnet member 350, which operates by an electrical signal, pushes and rotates the fixed frame, the moving frame 322 is separated from the fixed frame.

Next, the restoration frame 326 connected to the moving frame 322 presses and moves the moving frame 322 to its original position, the first point, so that the limiting unit 200 can quickly limit the movement of the wire. do.

It may be difficult for the driving unit 300 to move the moving frame 322 to the second point by human force due to the elasticity of the restoration frame 326.

In order to solve this problem, the above-described drive unit 300 may further include a pressing frame 340, and the pressing frame 340 presses the moving frame 322 in the direction opposite to the elastic force of the restoration frame 326. It can be moved from the first point to the second point.

Here, the pressing method of the moving frame 322 of the pressing frame 340 may vary.

For example, it may be arranged to pressurize the moving frame 322 while the member moves along the screw thread.

In addition, the pressing frame 340 may pressurize the moving frame 322 through a hydraulic or pneumatic cylinder, and in some cases may be provided with a telescopic pressing member depending on the length of the pressing.

In addition, even if the pressing member is moved through a motor and a rack and pinion gear, it will all be said to fall within the scope of the present invention.

Next, the stage equipment including the stage brake capable of controlling the load as described above will be described as follows.

The stage device (1) according to an embodiment of the present invention is provided on one side of the screw drum (SD) that winds a plurality of wires (W) connected to the set frame (C) that goes up and down on the stage, and includes the above-described wire (W) ) can be guided.

At this time, the screw drum (SD) can receive power through a motor and reducer to wind the wire (W).

The stage equipment 1 capable of load control according to an embodiment of the present invention may largely include a corresponding support part 1a and a load control part 1b.

The corresponding support portion 1a may be disposed on one side of the screw drum SD and may be sequentially arranged along the direction of the rotation axis of the screw drum SD to support the wire W.

Due to this corresponding support portion (1a), the plurality of wires (W) can be wound at a predetermined distance apart from each other on the screw drum (SD) without interfering with each other.

For example, the corresponding support portion 1a may be installed at every interval of the wire W where the unit roller is wound on the screw drum SD, and in this case, the unit roller is located on a virtual reference axis perpendicular to the rotation axis of the screw drum SD. It may have an inclined rotation axis.

Here, if the wires (W) can be wound at a predetermined interval on the screw drum (SD) without interfering with each other, the inclination of each unit roller can be varied, and it is natural that this does not limit the scope of the present invention. something to do.

At this time, the load control part 1b is provided between one side of the corresponding support part 1a and a direction change part to be described later to support the wire W.

At this time, the load applied to the load control unit 1b may exceed the preset load for various reasons, such as pinching of the wire W or pinching of the set frame C.

Therefore, the load control unit 1b may be provided to control the applied load by varying its position according to the change in the load applied due to the wire (W).

The load control unit 1b may specifically include a frame, an auxiliary roller, and a main roller.

The frame is provided on one side of the corresponding support part 1a and can play a role in holding the overall position of the load control part 1b and determining the positions of the auxiliary roller and main roller, which will be described later.

Next, the auxiliary roller may support the wire W upward by rotating along a first axis located at a preset first height from the bottom surface of the frame.

In other words, as shown in the drawing, the auxiliary roller may be provided to support the upper side of the outer circumference of the wire (W) at a higher position than the wire (W) based on the bottom surface of the frame.

At this time, the main roller may be disposed at a predetermined distance from the auxiliary roller and may downwardly support the wire (W) supported by the auxiliary roller.

For example, the main roller may be located at a first height and rotate along a second axis parallel to the first axis, and the lower side of the outer peripheral surface of the wire W may be supported on the upper side of the main roller.

The main roller having the above-described configuration may be provided to control the load by lowering the second axis to a second height lower than the above-described first height when the load applied due to the wire W exceeds a preset load. there is.

For example, the main roller lowers the second axis from the first height to the second height when the load applied by the wire W through the support member, reference member, and elastic member exceeds the preset load, and the applied load When the load becomes less than the preset load, the second axis can be returned from the second height to the first height.

First, the support member provided to rotate along the second axis may have a plurality of grooves formed so that the plurality of wires (W) can be supported while being spaced apart from each other in the second axis direction, where each of the plurality of grooves is connected to the wire (W). It can be prepared to be equal to the curvature of .

The reference member may be spaced a predetermined distance from the bottom surface of the frame and coupled to the second axis.

Accordingly, the reference member may descend in dependence on the descent of the second axis and may rise in dependence on the elevation of the second axis, as described above.

At this time, the standard member is prepared in the form of a plate with a 'ㄷ' standing on it, and the above-described support member is inserted into the open upper side, and the support member and the standard member can be axially coupled to the second axis.

Here, if the second axis can be coupled to move from the first height to the second height on the frame, the structure can be varied, and it is natural that the scope of the present invention is not limited thereby.

However, for more detailed explanation, for example, it would be convenient for the second axis to be arranged in a long hole formed in a vertical direction on the frame so that it can be moved along the long hole.

At this time, an elastic member may be provided between the bottom surface of the frame and the reference member to return the lowered reference member to its original position.

The load control unit having the configuration described above may further include a sensing member.

Specifically, the load control unit may detect that the second axis of the main roller is lowered to the second height through the sensing member.

For example, the sensing member may form a virtual plane or straight line having a third height lower than the second height through at least one light receiving/emitting sensor.

When the reference surface of the main roller, specifically the lower surface of the above-mentioned reference member, contacts the virtual plane or straight line formed in this way, it can be confirmed that the second axis is lowered to a second height lower than the first height. .

In addition, the main roller according to one embodiment of the ball invention may further include a cover that protects both ends of the second shaft that protrudes outward from the above-described frame.

Here, the cover is provided in a cylindrical shape with different diameters on one side and the opposite side, so that the outer surface has a curvature, so that when an external force is generated toward both ends of the second axis due to other external substances, the direction of the external force is changed and the external force is applied. This can prevent direct transmission toward the second axis.

At this time, the cover may further include a sealing member that prevents corrosion or damage due to moisture or foreign substances flowing into the cover.

Furthermore, the inner space of the cover may be filled with a gel-type filling member so that it cannot contact the second axis even if moisture or foreign matter enters the inner space through an unintended gap on the cover. In this case, the filling member is It would be natural to fill the entire internal space so as not to interfere with the rotation of the second axis.

As described above, when the cover includes a filling member, the filling member may contact the lower side of the second axis when the second axis is lowered and reduce the descending speed of the second axis to prevent damage to the second axis.

At this time, the brake for stage equipment capable of load control according to an embodiment of the present invention can ensure safety by restricting the movement of the wire when the above-described second axis is lowered to the second height.

Therefore, the brake for stage equipment capable of load control according to the present invention and the stage equipment including it control the load even when an external force is applied to the wire or set frame, preventing the occurrence of damage to part of the wire or problems with the traction device for unexpected reasons. can be prevented.

Specifically, the brake for stage equipment capable of controlling the load of the present invention has a structure that limits movement by pulling the wire toward the main unit, thereby shortening the time from when the brake is applied to when it stops.

At this time, even if multiple wires are arranged, the movement of all arranged wires can be restricted at the same time.

We have looked at preferred embodiments of the invention, and it is obvious to those skilled in the art that, in addition to the embodiments described above, the present invention can be embodied in other specific forms without departing from its spirit or scope. will be.

Therefore, the above-described embodiments are to be regarded as illustrative and not restrictive, and thus the present invention is not limited to the above description but may be modified within the scope of the appended claims and their equivalents.
