[0042] The principles and features of the present invention are described below with reference to the accompanying drawings. The examples given are for illustrative purposes only and are not intended to limit the scope of the invention. Unless otherwise specified, the mechanisms or structures described in the present invention can be implemented using existing conventional methods.

[0043] like Figures 1-10As shown, this embodiment of a stage performance device for multi-stage telescopic rotation includes a spherical rotating mechanism 100, a telescopic mechanism 200, and a support base 300. The telescopic mechanism 200 is obliquely mounted on the support base 300. A first drive mechanism 500 is mounted on the upper end of the telescopic mechanism 200, and the first output shaft 503 of the first drive mechanism 500 is vertically arranged. The spherical rotating mechanism 100 includes, from the outside to the inside, a hemispherical outer ring, a spherical middle ring, and a spherical inner ring arranged concentrically. The hemispherical outer ring and the spherical inner ring are fixed. The spherical inner ring is fitted between the spherical inner ring and the hemispherical outer ring, with the spherical inner ring arranged vertically. The hemispherical outer ring is fixed on the first output shaft 503 and can rotate under the drive of the first drive mechanism 500. The hemispherical outer ring is also provided with a second drive mechanism 600. The main structure of the second drive mechanism 600 is fixedly connected to the spherical inner ring, and the second output shaft 601 of the second drive mechanism 600 is connected to the spherical inner ring and drives the spherical inner ring to rotate relative to the hemispherical outer ring and the spherical inner ring.

[0044] like Figure 1 , Figure 2 and Figure 6 As shown, the hemispherical outer ring of this embodiment includes two intersecting and fixedly connected arc-shaped support ribs 104 and an annular connecting ring 105. The ends of the two arc-shaped support ribs 104 are respectively fixed to the connecting ring 105. Two second drive mechanisms 600 are symmetrically installed on the connecting ring 105. The first output shaft 503 is fixedly connected to the intersection of the two arc-shaped support ribs 104. By using two second drive mechanisms, the spherical inner ring can be driven to rotate, making the driving process more stable and reliable.

[0045] like Figure 1 , Figure 2 and Figure 6 As shown, the connecting ring 105 in this embodiment is arranged at an angle; the axis of the first output shaft 503 and the axis of the second output shaft 601 both pass through the center of the hemispherical outer ring, the spherical middle ring, and the spherical inner ring, making the overall structure stable and reliable. Specifically, the center of the connecting ring 105 is also the center of the hemispherical outer ring, the spherical middle ring, and the spherical inner ring. The lowermost end of the inclined connecting ring 105 is located on the side away from the telescopic mechanism, and the uppermost end of the inclined connecting ring 105 is located above the telescopic mechanism.

[0046] like Figure 1 , Figure 2 and Figure 6As shown, the spherical inner ring of this embodiment includes at least two intersecting and fixedly connected inner rings 102, and the spherical inner ring includes at least two intersecting and fixedly connected inner rings 103. The at least two inner rings 103 intersect at a first intersection point 106 and a second intersection point 107, respectively, and the line connecting the first intersection point 106 and the second intersection point 107 is vertically arranged. During performance, a person can stand inside the inner rings, ensuring an upright posture.

[0047] in, Figure 1 and Figure 2 The diagram shows a spherical inner ring with three intersecting inner rings 102. Due to overlapping structural lines in the diagram, the inner ring 103 of the spherical inner ring, the arc-shaped support rib 104 of the hemispherical outer ring, and the inner ring 102 of the spherical inner ring overlap and obscure each other. Figure 6 As shown in the structural diagram, the spherical inner ring includes two intersecting inner rings 103, and the spherical middle ring includes three middle rings 102. In this embodiment, all the inner rings 103 are fixedly connected to each other, and all the middle rings 102 are also fixedly connected to each other. The inner rings 103 are fitted inside the middle rings 102 and spaced apart from each other. The middle rings 102 are fitted inside the arc-shaped support ribs 104 and spaced apart from each other. The connection between the spherical inner ring, the spherical middle ring, and the hemispherical outer ring is mainly achieved through a second driving mechanism.

[0048] like Figure 1 , Figure 2 and Figure 5 As shown, in this embodiment, the second output shaft 601 is arranged horizontally; the first drive mechanism 500 includes a motor 501 and a rotary reducer 502. The motor 501 is connected to the rotary reducer 502 and drives the first output shaft 503 to rotate through the rotary reducer 502. The rotary reducer 502 is equivalent to a small slewing bearing, which provides power to drive the entire spherical rotating mechanism 100 to rotate through the motor.

[0049] Specifically, such as Figure 7 As shown, in this embodiment, the second output shaft 601 of the second drive mechanism 600 passes through the middle ring 102 and is fixedly connected to the middle ring 102. The second output shaft 601 may have a hollow structure. The main structure of the second drive mechanism 600 is fixedly connected to the inner ring 103 through a main connecting rod 602, and the main connecting rod 602 can be rotatably connected to the second output shaft 601. The main structure of the second drive mechanism 600 is fixed on the connecting ring 105 of the hemispherical outer ring.

[0050] like Figure 1 and Figure 8As shown, the telescopic mechanism 200 in this embodiment includes a telescopic drive unit 209, a multi-stage telescopic arm, and a wire rope pulley mechanism. The multi-stage telescopic arm is connected by the wire rope pulley mechanism. The telescopic drive unit 209 is installed on the outside of the multi-stage telescopic arm and drives the multi-stage telescopic arm to perform telescopic movement. The multi-stage telescopic arm adopts a nested box beam structure and uses the principle of movable pulleys to expand the stroke, thus doubling the stroke of the hydraulic cylinder.

[0051] Specifically, such as Figure 8 As shown, the multi-stage telescopic boom of this embodiment includes a first-stage telescopic boom 201, a second-stage telescopic boom 202, and a third-stage telescopic boom 203. The wire rope pulley mechanism includes a first wire rope 204, a second wire rope 205, a first pulley 206, and a second pulley 207. The second-stage telescopic boom 202 is telescopically fitted inside the third-stage telescopic boom 203, and the first-stage telescopic boom 201 is telescopically fitted inside the second-stage telescopic boom 202. One end of the first-stage telescopic boom 201 extending out of the second-stage telescopic boom 202 is inclined upward and equipped with a first drive mechanism 500. One end of the second-stage telescopic boom 202 extending out of the third-stage telescopic boom 203 is provided with a first pulley 206, and the other end of the second-stage telescopic boom 202 located inside the third-stage telescopic boom 203 is provided with a second pulley 207. One end of the first wire rope 204 is connected to the... The bottom of the telescopic cylinder of the three-stage telescopic boom 203 is connected. The other end of the first wire rope 204 passes over the first pulley 206 from the top of the second-stage telescopic boom 202 and is connected to the end of the first-stage telescopic boom 201 located inside the second-stage telescopic boom 202. One end of the second wire rope 205 is connected to the end of the first-stage telescopic boom 201 located inside the second-stage telescopic boom 202, and the other end of the second wire rope 205 passes over the second pulley 207 from the bottom of the second-stage telescopic boom 202 and is connected to the top of the three-stage telescopic boom 203. The telescopic drive unit 209 is connected to the outer wall of the three-stage telescopic boom 203 and the outer wall of the second-stage telescopic boom 202 respectively and drives the second-stage telescopic boom 202 to telescopically move within the three-stage telescopic boom 203, thereby driving the first-stage telescopic boom 201 to telescopically move within the second-stage telescopic boom 202.

[0052] Specifically, the telescopic drive unit 209 can be a hydraulic cylinder or a pneumatic cylinder. The two ends of the hydraulic cylinder or pneumatic cylinder can be installed on the outer side wall of the third-stage telescopic arm 203 and the outer side wall of the second-stage telescopic arm 202 respectively through ear plates. The hydraulic cylinder or pneumatic cylinder can be installed by hinge or by fixed installation. The purpose is to drive the second-stage telescopic arm 202 smoothly along the third-stage telescopic arm 203.

[0053] like Figure 1As shown, in this embodiment, the telescopic mechanism 200 is obliquely mounted on the support base 300 via a slewing bearing 400, and can rotate relative to the support base 300 under the drive of the slewing bearing 400. The tilt angle of the telescopic mechanism 200 can be set arbitrarily as needed.

[0054] like Figure 1 As shown, in this embodiment, the lower end of the telescopic mechanism 200 is connected to one end of the slewing bearing 400, and the middle part of the telescopic mechanism 200 is connected to the middle part of the slewing bearing 400 via a support plate 208. This provides effective support for the overall structure of the telescopic mechanism. Specifically, a steel bracket can be fixed above the slewing bearing 400, and the middle part of the telescopic mechanism 200 can be fixed to the steel bracket via the support plate 208. The slewing bearing 400 can adopt an existing general structure, specifically driven by a motor reducer 401, preferably by two symmetrically arranged motor reducers.

[0055] like Figure 9 As shown, the support base 300 in this embodiment is provided with multiple horizontal beams 301 and multiple vertical beams 302. The horizontal beams 301 and vertical beams 302 are arranged vertically. A first roller 303 with its axis perpendicular to the horizontal beam 301 is provided on each horizontal beam 301. A second roller 304 with its axis perpendicular to the vertical beam 302 is provided on each vertical beam 302. The first roller 303 and the second roller 304 are respectively mounted on the horizontal beams 301 and vertical beams 302, and can be moved vertically up and down via a vertical adjustment mechanism. By providing the first roller and the second roller, different rollers can be used for the vertically arranged tracks, achieving the effect of the entire stage performance device moving on different tracks.

[0056] Specifically, the support base 300 can adopt a square structure and can be driven by a self-driving method. The slewing bearing 400 is installed at the center of the square support base 300.

[0057] like Figure 4 As shown, the vertical adjustment mechanism in this embodiment includes a hinge plate 305. The first roller 303 or the second roller 304 is rotatably connected to the hinge plate 305. One end of the hinge plate 305 is hinged to the support base 300, and the other end of the hinge plate 305 is detachably connected to the support base 300 via a vertically arranged adjusting bolt 306. A tension spring 307 is also provided near the other end of the hinge plate 305, and the tension spring 307 is connected to the support base 300. The distance the first roller or the second roller extends from the bottom of the support base can be adjusted by changing the connection length of the adjusting bolt. Specifically, as shown... Figure 4As shown, a connecting ear plate 308 can be provided in the support base 300, with the connecting ear plate 308 facing downwards, and one end of the hinge plate 305 is hinged to the connecting ear plate 308.

[0058] In this embodiment, the multi-stage telescopic and rotating stage performance device allows the user to stand within the inner ring 103, which remains vertical at all times. The first drive mechanism 500 drives the spherical rotating mechanism 100 to rotate around the first output shaft 503. The second drive mechanism 600 drives the middle ring 102 to rotate relative to the inner ring 103 and the hemispherical outer ring, enhancing the stage effect. Furthermore, the slewing bearing 400 can drive the telescopic mechanism 200 and the spherical rotating mechanism 100 to rotate, enabling three rotational actions. These actions can be performed simultaneously, alternately, or a combination thereof, increasing the richness and diversity of the performance. The telescopic mechanism 200 can also drive the spherical rotating mechanism 100 to telescopically extend and retract, and the support base 300 can move along different tracks as needed.

[0059] This embodiment of a multi-stage telescopic and rotating stage performance device can be used as a stage armillary sphere. The spherical rotating mechanism can rotate under the drive of the first driving mechanism, and the spherical inner ring can rotate relative to the hemispherical outer ring and the spherical inner ring under the drive of the second driving mechanism. The telescopic mechanism can also realize the telescopic function and can also rotate relative to the support base. It can integrate the three rotational actions with the telescopic actions to realize a variety of complex stage actions, making the stage props more three-dimensional and the performance forms more diverse.
