Detailed Implementation

[0019] The present invention will be further described in detail below with reference to the accompanying drawings and through embodiments. The following embodiments are explanations of the present invention, but the present invention is not limited to the following embodiments.

[0020] See Figures 1-5 This embodiment of a rotating and lifting stage includes a platform 1 and a lift 2. The platform 1 is set on the platform 21 of the lift 2. The platform 1 is circular and includes several concentric rings. A drive mechanism 3 is provided in the platform 1 to drive each ring to rotate.

[0021] This invention achieves the lifting effect of the stage by using a lift 2 to drive the platform 1 to move up and down. By dividing the circular platform 1 into multiple rotatable rings, and using a drive mechanism 3 to drive each ring to rotate, it is possible to control the different rings to rotate in different directions, thereby improving the expressiveness of the stage and meeting the needs of modern performances for diverse movements and scene changes.

[0022] See Figure 1 , Figure 2 The platform 1 includes an outer ring 11, an inner ring 12, and a central circle 13. The inner ring 12 is rotatably disposed on the outside of the central circle 13, and the outer ring 11 is rotatably disposed on the outside of the inner ring 12. A lifting mechanism 4 is provided on the lower side of the inner ring 12 and the lower side of the central circle 13 to drive the inner ring 12 and the central circle 13 to move up and down.

[0023] The lifting mechanism 4 drives the inner ring 12 to move upward, so that the inner ring 12 and the outer ring 11 form a stepped shape. The lifting mechanism 4 also drives the center circle 13 to move upward, so that the center circle 13 and the inner ring 12 form a stepped shape. This transforms the flat platform 1 into a shape where the center circle 13 is higher and the inner ring 12 and the outer ring 11 are lower in sequence. This allows multiple performers to be positioned at different locations on the platform 1, reducing the obstruction effect of the outer performers on the inner performers. It also makes it easier to place different items on the platform 1 in a stepped shape, which enhances the expressiveness of the stage.

[0024] See Figure 1 , Figure 3 , Figure 4The drive mechanism 3 includes three motor groups, namely the first motor group 31, the second motor group 32 and the third motor group 33. The first motor group 31, the second motor group 32 and the third motor group 33 drive the rotation of the outer ring 11, the inner ring 12 and the central circle 13 respectively. Each motor group includes four servo motors arranged at equal intervals around the circumference. A gear 34 is fixed on the rotating shaft of the servo motor. The inner sides of the outer ring 11, the inner ring 12 and the central circle 13 are provided with internal gear rings 35 that mesh with the gears 34 in the corresponding motor group.

[0025] The servo motor can precisely control the rotation speed of the gear 34. The gear 34 meshes with the internal gear ring 35, allowing the first motor group 31, the second motor group 32, and the third motor group 33 to control the rotation of the outer ring 11, the inner ring 12, and the central circle 13 respectively. This enables the outer ring 11, the inner ring 12, and the central circle 13 to rotate in different directions and at different speeds, achieving precise control of the rotation speed to meet the performance requirements of various shows. Each motor group includes four evenly distributed servo motors, which improves the force balance when the servo motors drive the outer ring 11, the inner ring 12, and the central circle 13 to rotate, thus enhancing the stability of their rotation.

[0026] See Figure 1 , Figure 3 , Figure 4 The lifting mechanism 4 includes two electric cylinder groups, namely the first electric cylinder group 41 and the second electric cylinder group 42. The first electric cylinder group 41 and the second electric cylinder group 42 drive the inner ring 12 and the central circle 13 to move up and down respectively. Each electric cylinder group includes four electric cylinders distributed at equal intervals around the circumference. The cylinder body 43 of the first electric cylinder group 41 is fixed on the outer ring 11, and the piston 44 of the first electric cylinder group 41 abuts against the inner ring 12. The cylinder body 43 of the second electric cylinder group 42 is fixed on the inner ring 12, and the piston 44 of the second electric cylinder group 42 abuts against the central circle 13.

[0027] The first electric cylinder assembly 41 drives the inner ring 12 to move up and down relative to the outer ring 11, and the second electric cylinder assembly 42 drives the central circle 13 to move up and down relative to the inner ring 12. This achieves the effect of adjusting the inner ring 12 and the central circle 13 to different heights, allowing the platform 1 to be adjusted into various shapes and increasing its applicability to different performance needs. Each electric cylinder assembly includes four electric cylinders distributed at equal intervals around the circumference, which improves the force balance when the electric cylinder assembly drives the inner ring 12 and the central circle 13 to move up and down, and enhances the stability of the inner ring 12 and the central circle 13 during this movement.

[0028] See Figure 4The pistons 44 of the first electric cylinder group 41 and the second electric cylinder group 42 are each rotatably equipped with rollers 45, which rotate in contact with the bottom surfaces of the inner ring 12 and the center circle 13.

[0029] The roller 45 reduces the frictional resistance between the inner ring 12 and the center circle 13 and the top of the piston 44 during rotation, thereby reducing the risk that the inner ring 12 and the center circle 13 will get stuck and unable to rotate due to excessive resistance. At the same time, it also reduces the noise generated by friction when the inner ring 12 and the center circle 13 rotate.

[0030] See also, 3. Figure 4 The first motor assembly 31 is fixed on the platform 21 of the elevator 2, the outer ring 11 is rotatably mounted on the platform 21 of the elevator 2, the pistons 44 of the first electric cylinder assembly 41 and the second electric cylinder assembly 42 are fixed with mounting brackets 46, the second motor assembly 32 is fixed on the mounting bracket 46 on the first electric cylinder assembly 41, and the third motor assembly 33 is fixed on the mounting bracket 46 on the second electric cylinder assembly 42.

[0031] When the first electric cylinder assembly 41 drives the inner ring 12 to move up and down, the second motor assembly 32, under the action of the mounting bracket 46, moves up and down with the piston 44 of the first electric cylinder assembly 41. This ensures that the gear 34 of the second motor assembly 32 is always engaged with the internal gear ring 35 of the inner ring 12, enabling the inner ring 12 to rotate under the drive of the second motor assembly 32 at different heights. Similarly, when the second electric cylinder assembly 42 drives the center circle 13 to move up and down, the third motor assembly 33, under the action of the mounting bracket 46, moves up and down with the piston 44 of the second electric cylinder assembly 42. This ensures that the gear 34 of the third motor assembly 33 is always engaged with the internal gear ring 35 of the center circle 13, enabling the center circle 13 to rotate under the drive of the third motor assembly 33 at different heights. This ensures that the lifting and rotating effects of the inner ring 12 and the center circle 13 do not interfere with each other.

[0032] See Figure 4 , Figure 5 In this utility model, the platform 21 of the lifting machine 2 has several through holes 22 for passing wires and conductive rods to supply power to the three motor groups and two electric cylinder groups. The power supply method is as follows:

[0033] The first motor unit 31 is fixed on the platform 1, so the wires are directly passed through the through hole 22 to connect the first motor unit 31 and the power supply to achieve power supply.

[0034] The second motor assembly 32 and the first electric cylinder assembly 41 are mounted on the outer ring 11. An annular first conductive ring 5 is provided on the inner side of the outer ring 11. The second motor assembly 32 and the first electric cylinder assembly 41 are electrically connected to the first conductive ring 5 via wires. A first conductive rod 51 for connecting to the power supply is fixed in the through hole 22 near the first conductive ring 5. The metal contacts on the first conductive rod 51 are in electrical contact with the first conductive ring 5, so that when the first conductive ring 5 rotates with the outer ring 11, the second motor assembly 32 and the first electric cylinder assembly 41 can be powered through the first conductive rod 51.

[0035] The third motor assembly 33 and the second electric cylinder assembly 42 are mounted on the inner ring 12. A second conductive ring 6 is provided on the inner side of the inner ring 12. The third motor assembly 33 and the second electric cylinder assembly 42 are electrically connected to the second conductive ring 6 via wires. A second conductive rod 61 for connecting to the power supply is slidably mounted on the through hole 22 near the second conductive ring 6. The metal contacts on the second conductive rod 61 are in electrical contact with the second conductive ring 6. The second conductive ring 6 is provided with an annular protrusion 62, which is engaged between the two metal contacts of the second conductive rod 61. Therefore, when the second conductive ring 6 moves up and down with the inner ring 12, it can drive the second conductive rod 61 to move up and down, ensuring that the second conductive rod 61 and the second conductive ring 6 are always in electrical contact. This enables the third motor assembly 33 and the second electric cylinder assembly 42 to be powered through the second conductive rod 61 when the second conductive ring 6 rotates and moves up and down with the inner ring 12.

Those skilled in the art to which this invention pertains may make various modifications or additions to the described specific embodiments or use similar methods to replace them, as long as they do not depart from the content of this specification or exceed the scope defined in the claims, all of which shall fall within the protection scope of this invention.
