[0002] A rotating and lifting stage is a stage equipment that combines lifting and rotation functions. It is widely used in theaters, concert halls, auditoriums, cinemas, and other performance venues, as well as in occasions requiring dynamic scene displays, such as car showrooms and wedding events. In the prior art, patent CN 109057416 A discloses a rotating and lifting stage structure, including a fixed frame and a drive device. The fixed frame is fixedly connected to a fixed spiral frame, which is connected to a spiral lifting stage. The drive device is connected to a rotating drive frame, which is sleeved with the fixed spiral frame and connected to the spiral lifting stage. This invention solves the technical problem in the prior art where the lifting and rotation of the stage requires two drive systems, increasing manufacturing costs. This device achieves synchronous movement of the stage's lifting and rotation through a single drive system. However, in performances and exhibitions, the audience positions vary, requiring horizontal angle adjustment of performers and displayed items. The stage of this device cannot be horizontally rotated independently, affecting the stage's usability. Furthermore, the device lacks detection elements for stage rotation and lifting, and the accuracy of position adjustment needs improvement.

The pawl 553 is respectively fitted with the spring plate 554 and the ratchet 552. Four annularly distributed rotating shafts 555 are rotatably connected to the upper side of the base 51 via a third bearing. Each rotating shaft 555 has a second gear 556 at its lower end, which meshes with the first gear 551. Each rotating shaft 555 has a... A reciprocating lead screw 557 is provided, and crescent locks 9 are slidably connected to the outer side of the reciprocating lead screw 557. A lifting cylinder 558 is provided on the outer side of each crescent lock 9. An annular seat 559 is provided between the upper ends of the lifting cylinders 558. The annular seat 559 is rotatably connected to the lower groove of the annular seat 559 via a large-diameter bearing. The detection component 56 includes an angle sensor 561 and a laser sensor 562. The laser sensor 562 is disposed on the bottom wall of the base 1. An angle sensor 561 is provided in the upper middle part of the base 51. The detection end of the angle sensor 561 is fixedly connected to the outer side of the hollow shaft 52. Both the angle sensor 561 and the laser sensor 562 are bidirectionally electrically connected to the microcontroller 2. The control mechanism 5 also includes a servo motor 57, a motor brake 58, and a reducer. Speed ​​reducer 59, servo motor 57, motor brake 58, and reducer 59 are all mounted on the bottom wall of the base 1. The output shaft 1 of servo motor 57 is fixedly connected to the input shaft 1 of motor brake 58. The output shaft 2 of motor brake 58 is fixedly connected to the input shaft 2 of reducer 59. The output shaft 3 of reducer 59 is fixedly connected to the lower end of hollow shaft 52. The input ends of servo motor 57 and motor brake 58 are electrically connected to the output end of microcontroller 2. The upper outer side of rotating shaft 555 is rotatably connected to annular seat 2 6 through bearing 4. Bellows 7 are provided between annular seat 2 6 and the vertically adjacent lifting cylinder 558. Bellows 7 are movably sleeved on the outer side of the adjacent reciprocating screw 557. Four arc-shaped protective shells 8 are provided on the upper side of base 51.The upper ends of the hollow shaft 52 and the rotating shaft 555 both pass through the top wall of the corresponding arc-shaped protective shell 8. Gear 1 551, ratchet 552, pawl 553, spring plate 554, and gear 2 556 are all located inside the four arc-shaped protective shells 8. When using the rotating and lifting stage, the microcontroller 2 starts the servo motor 57 and the motor brake 58. When the motor brake 58 is energized, the electromagnet coil generates magnetic force to attract the armature, causing the brake shoe to separate from the brake wheel, making the output shaft 1 of the servo motor 57 rotate in the forward direction. When the motor brake 58 is de-energized, the spring returns to its original position, the brake shoe grips the brake wheel to generate braking torque, forcing the output shaft 1 of the servo motor 57 to stop quickly. The output shaft 2 of the motor brake 58 drives the input shaft 2 of the reducer 59 to rotate. The reducer 59 The internal transmission of gears reduces the speed of the output shaft 3 of the reducer 59 and increases its torque. The output shaft 3 of the reducer 59 drives the hollow shaft 52 to rotate synchronously. The hollow shaft 52 is slidably engaged with the guide bar and the guide groove 54, thereby causing the solid shaft 53 to drive the stage base 4 to rotate synchronously in the forward direction. The hollow shaft 52 drives the ratchet 552 to rotate synchronously in the forward direction. During the forward rotation of the ratchet 552, the four sets of pawls 553 on gear 1 551 are engaged with the ratchet 552, causing gear 1 551 to rotate synchronously with the ratchet 552. Gear 1 551 is meshed with gear 2 556, thereby causing gear 2 556 to drive the corresponding rotating shaft 555 synchronously. The rotating shaft 555 drives the corresponding reciprocating screw 557 to rotate synchronously in reverse. During the reverse rotation of the reciprocating screw 557, it drives the crescent lock 9 to move vertically back and forth (the arc-shaped protrusion of the crescent lock 9 is embedded in the groove of the spiral groove of the reciprocating screw 557, and its curved contour is in close contact with the side wall of the spiral groove to form a sliding pair. The rotation of the spiral groove will push the crescent lock 9 to move axially, realizing linear reciprocating motion). The crescent lock 9 drives the lifting cylinder 558 to move vertically back and forth synchronously. The four lifting cylinders 558 drive the stage base 4 to move vertically synchronously through the annular seat 559, so that the stage base 4 rotates while being raised and lowered. During this process, the microcontroller 2 activates the laser sensor 562, and the laser sensor 562 emits a light signal to illuminate the stage. The lower side of the stage base 4 reflects the light back to its initial position. Based on the propagation time and speed of the light signal, the lifting height of the stage base 4 is obtained, and this result is transmitted to the microcontroller 2 as an electrical signal. The microcontroller 2, based on this result and its own timing element, regulates the forward rotation time of the output shaft of the servo motor 57, thereby precisely controlling the lifting height of the stage base 4. When the stage base 4 is rotated independently, the microcontroller 2 controls the servo motor 57 to rotate its output shaft in the reverse direction. Subsequently, the hollow shaft 52, using the same principle, utilizes the sliding engagement between the guide bar and the guide groove 54, thereby driving the stage base 4 to rotate synchronously in the reverse direction via the solid shaft 53. The hollow shaft 52 drives the ratchet 552 to rotate synchronously in the reverse direction. During the reverse rotation of the ratchet 552...The pawl 553 on gear 551 contacts and separates from the ratchet 552 through arc-shaped contact compression (the pawl 553 is always in elastic contact with the ratchet 552 through the spring plate 554, which is made of phosphor bronze elastic material. When subjected to external force, the material deforms and returns to its original shape after the external force is removed). This prevents gear 551 from rotating synchronously with the ratchet 552. At this time, the height of stage base 4 remains unchanged. Simultaneously, the microcontroller 2 activates the angle sensor 561. The angle sensor 561 uses a high-performance integrated magnetic sensing element. It uses the non-contact characteristic of magnetic signal sensing to measure the rotation angle of the detection end (i.e., hollow shaft 52) ​​and transmits the measurement result to the microcontroller 2 as an electrical signal. The microcontroller 2 controls the reverse rotation of the output shaft of the servo motor 57 to stop based on the result, thereby realizing the rotation angle of stage base 4. The stage features precise, individual control. A bellows 7, a corrugated structure made of multiple layers of laminated metal sheets, lubricates and protects the exposed end of the reciprocating screw 557 from dust. Its working principle involves elastic deformation to achieve self-adaptive sealing, maintaining excellent sealing performance. An arc-shaped protective shell 8 protects gear 551, ratchet 552, pawl 553, spring 554, and gear 556 from dust. The spring 554 needs periodic replacement by removing the arc-shaped protective shell 8 to prevent aging. The device uses a single drive element to achieve stage lifting and rotation. The ratchet, pawl, and screw drive work together to allow for independent horizontal rotation adjustment, improving the stage's usability. Furthermore, both lifting and rotation are assisted by detection elements, enhancing the precision of these adjustments.

[0025] The working principle of the rotating and lifting stage structure provided by this utility model is as follows: When using the rotating and lifting stage, the microcontroller 2 starts the servo motor 57 and the motor brake 58. When the motor brake 58 is energized, the electromagnet coil generates magnetic force to attract the armature, causing the brake shoe to separate from the brake wheel, so that the output shaft of the servo motor 57 rotates in the forward direction. When the motor brake 58 is de-energized, the spring returns to its original position, the brake shoe grips the brake wheel to generate braking torque, forcing the output shaft of the servo motor 57 to stop quickly. The output shaft of the motor brake 58 drives the input shaft of the reducer 59 to rotate. The internal gear transmission of the reducer 59 reduces the speed of the output shaft of the reducer 59 and increases the torque of the output shaft of the reducer 59. The output shaft of the reducer 59 drives the hollow shaft 52 to rotate synchronously. The hollow shaft 52 slides and engages with the guide bar and guide groove 54, causing the solid shaft 53 to drive the stage base 4 to rotate synchronously in the forward direction. The hollow shaft 52 drives the ratchet 552 to rotate synchronously in the forward direction. During the forward rotation of the ratchet 552, the four sets of pawls 553 on gear 1 551 engage with the ratchet 552, causing gear 1 551 to rotate synchronously with the ratchet 552. Gear 1 551 meshes with gear 2 556, causing gear 2 556 to drive the corresponding rotating shaft 555 to rotate synchronously in the reverse direction. The rotating shaft 555 drives the corresponding reciprocating screw 557 to rotate synchronously in the reverse direction. During the reverse rotation of the reciprocating screw 557, it drives the crescent lock 9 to move vertically back and forth (the arc-shaped protrusion of the crescent lock 9 is embedded in the reciprocating screw 557). In the channel of the spiral groove, its curved contour is in close contact with the sidewall of the spiral groove, forming a sliding pair. The rotation of the spiral groove will push the crescent lock 9 to move axially, realizing linear reciprocating motion. The crescent lock 9 drives the lifting cylinder 558 to move vertically reciprocating synchronously. The four lifting cylinders 558 drive the stage base 4 to move vertically synchronously through the annular seat 559, so that the stage base 4 rotates while being raised and lowered. During this process, the microcontroller 2 activates the laser sensor 562. The laser sensor 562 emits a light signal to illuminate the lower side of the stage base 4 and reflects it back to the initial position. The lifting height of the stage base 4 is obtained according to the propagation time and speed of the light signal, and the result is transmitted to the microcontroller 2 in the form of an electrical signal. The microcontroller 2 uses this result and its own timing element to control the servo motor 57. The forward rotation time of the output shaft is adjusted to precisely control the lifting height of the stage base 4. When the stage base 4 is rotated independently, the microcontroller 2 controls the servo motor 57 to rotate its output shaft in reverse. Subsequently, the hollow shaft 52, through the same principle, uses the sliding engagement between the guide bar and the guide groove 54 to drive the stage base 4 to rotate synchronously in reverse via the solid shaft 53. The hollow shaft 52 drives the ratchet 552 to rotate synchronously in reverse. During the reverse rotation of the ratchet 552, the pawl 553 on the gear 551 contacts and separates from the ratchet 552 through arc-surface contact compression (the spring plate 554 ensures that the pawl 553 is always in elastic contact with the ratchet 552). The spring plate 554 is made of phosphor bronze elastic material, which deforms when subjected to external force.After the external force is removed, the material recovers its original shape due to its own elasticity, causing gear 551 to not reverse synchronously with ratchet 552. At this time, the lifting height of stage base 4 remains unchanged. Simultaneously, microcontroller 2 activates angle sensor 561. Angle sensor 561 uses a high-performance integrated magnetic sensing element, utilizing the non-contact characteristic of magnetic signal sensing to measure the rotation angle of the detection end (i.e., hollow shaft 52), and transmits the measurement result to microcontroller 2 as an electrical signal. Based on this result, microcontroller 2 controls the reverse rotation of the output shaft of servo motor 57 to stop, thereby realizing the control of stage base 4. The rotation angle can be precisely controlled individually. A bellows 7 is used to wrap, lubricate, and protect the exposed end of the reciprocating screw 557 from dust. The bellows 7 is a corrugated structure made of multiple layers of stacked metal sheets. Its working principle is to achieve self-adaptive sealing through elastic deformation to maintain good sealing performance. An arc-shaped protective shell 8 protects gear 551, ratchet 552, pawl 553, spring plate 554, and gear 556 from dust. The device requires periodic replacement of the spring plate 554 by removing the arc-shaped protective shell 8 to prevent aging of the spring plate 554.

The microcontroller 2 controls the angle sensor 561, the laser sensor 562, the servo motor 57, and the motor brake 58 using methods commonly used in the prior art.
