[0022] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0023] In modern stage design, the stage is an important part of the performance space. In order to create a lively three-dimensional performance effect, many machines on the stage need to be mounted with steel wires to guide equipment such as follow-spots and cameras to their optimal positions and assist in the stage lighting and shadow effects. Therefore, steel wires are used more and more frequently. However, during the use of general steel wires, the guiding direction of the steel wires changes with the displacement of the equipment. When the mounted equipment needs to be stable, it is necessary to ensure that the steel wires can be mounted stably. However, the steel wires are relatively thin and difficult to restrain. In addition, friction is more likely to occur between the steel wires and the restraining devices, and the steel wires are easily damaged and broken by friction, which may cause instrument losses at the least and safety hazards to stage performers at the worst.

[0024] Embodiment 1: Figure 1 , 2 The figure is only one of the embodiments of the present invention, a stage wire mounting auxiliary device, including a mounting column 1 for mounting a wire rope 3 and a mounting seat 2 connected to the mounting column 1, wherein at least a portion of the mounting column 1 is located in the mounting seat 2, a horizontal groove 11 is provided on the outer side of the mounting column 1, and an extension column 21 extending in the direction of the mounting column 1 is provided on the mounting seat 2, and one end of the extension column 21 away from the mounting column 1 is connected to the mounting seat 2 through a spring 22, and a limiting plate 23 for limiting the extension direction of the extension column 21 is provided on the side of the mounting seat 2 close to the mounting column 1, an electromagnetic component 12 and a shaft rod 13 coaxially arranged with the electromagnetic component 12 are provided in the mounting column 1, a rotating motor 14 for driving the shaft rod 13 is provided above the mounting column 1, and the extension column 21 is a magnetic component.

[0025] In the present invention, the mounting column 1 is connected to the steel wire rope 3, and the mounting seat 2 can be fixed on the upper steel beam of the stage. The mounting column 1 with the steel wire rope 3 passes through the mounting seat 2, and the extending column 21 on the mounting seat 2 extends out to resist the horizontal groove 11 of the mounting column 1. At this time, the mounting column 1 cannot move up and down, thereby ensuring that the steel wire rope 3 no longer expands and contracts, and ensuring that the instrument mounted on the steel wire rope 3 will not move around.

[0026] First, the structure of the mounting column 1. At least a part of the mounting column 1 is located in the mounting seat 2. A horizontal groove 11 is arranged on the outer side of the mounting column 1. The mounting column 1 can be cylindrical or square. It is only necessary to open a horizontal groove 11 horizontally on the outer wall of the mounting column 1 to facilitate the extension column 21 to extend into the horizontal groove 11.

[0027] Here, the mounting column 1 can be arranged at the end of the steel wire rope 3, so that the length of the steel wire rope 3 mounted each time is fixed.

[0028] The mounting column 1 can also be set in the middle of the wire rope 3, so that multiple mounting columns 1 can be set in the middle of the wire rope 3. The upper end of the wire rope 3 can be controlled by a winch to retract and release. When the wire rope 3 is retracted to a certain mounting column 1 just reaching the mounting seat 2, the mounting seat 2 is used to fix the mounting column 1. At this time, the hanging length of the wire rope 3 is the distance between the mounting column 1 and the lower end of the wire rope 3.

[0029] Even, the end and the middle of the steel wire rope 3 can be provided with mounting columns 1 at the same time, so that multi-stage mounting can be realized.

[0030] Next is the structure of the mounting seat 2, the mounting seat 2 is provided with an extension column 21 extending in the direction of the mounting column 1, the end of the extension column 21 away from the mounting column 1 is connected to the mounting seat 2 via a spring 22, and the side of the mounting seat 2 close to the mounting column 1 is provided with a limiting plate 23 for limiting the extension direction of the extension column 21, the extension column 21 extends forward from the rear end of the mounting seat 2 to the direction of the mounting column 1, the spring 22 facilitates the extension column 21 to return to the initial position, the limiting plate 23 limits the extension direction of the extension column 21, to prevent the extension column 21 from flipping downward when the mounting column 1 is mounted on the extension column 21, causing the mounting column 1 and the wire rope 3 to slip.

[0031] Of course, a limiting hole is provided on the limiting plate 23 to facilitate the passage of the extending column 21, and the diameter of the limiting hole is just equal to the outer diameter of the extending column 21, which is optimal, and the limiting hole is arranged horizontally, so as to ensure that the angle formed between the extending column 21 and the mounting column 1 is in the range of 80° to 100°. In fact, the extending column 21 and the mounting column 1 are arranged vertically.

[0032] Finally, the extension column 21 of the mounting seat 2 is controlled. The mounting column 1 is provided with an electromagnetic component 12 and a shaft 13 coaxially arranged with the electromagnetic component 12. A rotating motor 14 for driving the shaft 13 is provided above the mounting column 1. The extension column 21 is a magnetic component. The rotating motor 14 is started to drive the electromagnetic component 12 to rotate through the rotating shaft 13. After the electromagnetic component 12 is energized and magnetized, it rotates under the drive of the rotating motor 14. If the electromagnetic component 12 is close to the magnetic pole on one side of the extension column 21 as a magnetic component and the extension column 21 is close to the magnetic pole on the extension column 21, the extension column 21 is closed. The magnetic poles of the column 21 on the side close to the electromagnetic component 12 are opposite. At this time, the extended column 21 is ejected by the attraction of opposite poles and is stuck in the horizontal groove 11 of the mounting column 1. At this time, the mounting column 1 cannot be moved up and down; on the contrary, if the magnetic pole of the side of the extended column 21 close to the electromagnetic component 12 is the same as the magnetic pole of the extended column 21 on the side close to the electromagnetic component 12, the extended column 21 is repelled by the repulsive force of like poles and retracts, and moves out of the horizontal groove 11 of the mounting column 1. At this time, the mounting column 1 is unlocked and can be moved up and down.

[0033] Of course, a power source for supplying power to the electromagnetic component 12 and the rotating motor 14 is provided in the mounting column 1 .

[0034] In short, when the steel wire rope 3 needs to be fixed and restrained, the steel wire rope 3 is retracted and released until the mounting column 1 is just located between the mounting seat 2, and the rotating motor 14 is started to drive the electromagnetic part 12 to rotate to attract the extension column 21. At this time, the extension column 21 extends and clamps the mounting column 1, completing the fixed restraint of the steel wire rope 3. When the mounting is completed, the rotating motor 14 is started again to drive the electromagnetic part 12 to rotate 180 degrees, and the magnetic pole of the electromagnetic part 12 can be replaced. At this time, the electromagnetic part 12 repels the extension column 21, and the extension column 21 retracts. At this time, the mounting column 1 and the steel wire rope 3 can move up and down.

[0035] The stage wire mounting auxiliary device of the present invention has the advantages of simple structure, high wire mounting stability, non-trivial wire damage and high safety, and can lock the wire when stable mounting is required and release the wire when stable mounting is not required.

[0036] Embodiment 2, still as Figure 1 , 2 The figure is only one embodiment of the present invention. In order to make the mounting effect of the stage wire mounting auxiliary device of the present invention better and more stable, the present invention also has the following designs:

[0037] Firstly, at least a portion of the mounting column 1 is arc-shaped, and the upper and lower side walls of the mounting column 1 are arc-shaped, so that it is convenient for the mounting column 1 to penetrate into the mounting seat 2.

[0038] Then, the number of the springs 22 is at least one, and the extending column 21 is connected to the spring 22 via an elastic gasket 211, so that the elastic force of the extending column 21 received by the multiple springs 22 is relatively balanced. It should be noted that the spring 22 is a contraction spring, which drives the extending column 21 to contract back, and the elastic force of the spring 22 is smaller than the magnetic force of the electromagnetic component 12.

[0039] Furthermore, the electromagnetic component 12 is a cylindrical component, which is convenient for rotating inside the mounting column 1 .

[0040] In addition, there are two protruding columns 21, and the connecting line between the two protruding columns 21 passes through the axis of the electromagnetic component 12. In fact, a protruding column 21 is provided at each end of the mounting column 1. The two protruding columns 21 are extended at the same time, and the mounting stability of the mounting column 1 is higher.

[0041] Of course, the magnetic poles of the two protruding columns 21 at one end close to the mounting column 1 are opposite, so that the two protruding columns 21 are subjected to the same magnetic force of the electromagnetic component 12 in the mounting column 1, and the two protruding columns 21 are simultaneously attracted by the electromagnetic component 12, or simultaneously repelled by the electromagnetic component 12.

[0042] In addition, at least a portion of a side of the extending column 21 close to the mounting column 1 is arc-shaped, so that it is convenient for the extending column 21 to extend into the horizontal groove 11 .

[0043] Finally, a shockproof plate 15 for connecting to the steel wire rope 3 is provided at the lower end of the mounting column 1. In fact, it is to prevent the steel wire rope 3 from being subjected to excessive tension caused by instantaneous acceleration when the mounting column is displaced. The shockproof plate 15 has a certain toughness and is used as a buffer when the mounting column 1 is displaced.

[0044] The stage wire mounting auxiliary device of the present invention has the advantages of simple structure, high wire mounting stability, non-trivial wire damage and high safety, and can lock the wire when stable mounting is required and release the wire when stable mounting is not required.

[0045] The present invention is not limited to the above specific implementations, and the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made to the above implementations based on the technical essence of the present invention shall be included in the protection scope of the present invention.
