Description

Technical Field

[0001] This utility model relates to the field of lifting stage technology, and in particular to a rotary performance lifting mechanical device. Background Technology

[0002] Rotating and lifting stages are one of the core pieces of equipment in modern theaters and performance venues. Their structure typically includes a base, lifting mechanism, rotating platform, and control system. They can dynamically change the stage space, enhancing the visual effects and narrative flexibility of performances, and are widely used in theaters, concerts, television stations, and other settings. With technological advancements, integration, modularization, and intelligence have become major trends. As performing arts and technology deeply merge, rotating and lifting stages have become an indispensable core piece of equipment in modern theaters. By dynamically changing the stage space and perspective, they create an immersive audiovisual experience for the audience, greatly enriching the expressive forms of stage art. However, under current technological conditions, rotating and lifting stages still have many shortcomings in terms of structural design and functional implementation.

[0003] Current rotating lifting stages all use hydraulic telescopic rods to drive the lifting platform. Hydraulic telescopic rods pose a risk of cylinder failure, resulting in a lower safety factor compared to fully mechanical systems. Secondly, when using rotating lifting platforms for performances, the stage often begins to rise or fall before the performers are even positioned in the center, leading to various safety accidents. Furthermore, due to the limitations of stage usage, it is impossible to install guardrails on the stage surface, posing a significant safety risk. Therefore, further improvements are needed. To this end, we have proposed a rotating performance lifting mechanism. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology and propose a rotary performance lifting mechanism.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a rotary performance lifting mechanism, comprising a slot, a lifting plate, and a scissor-type folding mechanism. The scissor-type folding mechanism is hinged between the slot and the lifting plate. A driving component for folding or unfolding the scissor-type folding mechanism is installed inside the slot. A guide component connected to the scissor-type folding mechanism is installed on the lower surface of the lifting plate. A rotating plate is provided on the upper surface of the lifting plate, and a groove is formed in the middle of the upper surface of the rotating plate. A through hole is formed in the bottom wall of the groove. A vertical tube is fixed in the middle of the upper surface of the lifting plate. The vertical tube and the inner wall of the through hole are rotatably connected by a bearing. A pressure measuring component is provided in both the vertical tube and the groove. A second motor for driving the rotating plate to rotate is installed on the side of the lower surface of the lifting plate. A controller is provided inside the slot.

[0006] Furthermore, the driving assembly includes a lead screw rotatably connected to the side wall of the slot seat, a movable plate rotatably connected to the surface of the lead screw via a thread, and the movable plate slidably connected to the slot seat. A first fixed seat is fixed to one side of the inner side wall of the slot seat. The bottom ends of the scissor folding mechanism are respectively hinged to the first fixed seat and the movable plate. The guiding assembly includes a T-shaped guide rail fixed to the lower surface of the lifting plate, and a slide block is slidably connected to the surface of the T-shaped guide rail. A second fixed seat is fixed to the other side of the lower surface of the lifting plate. The top ends of the scissor folding mechanism are respectively hinged to the slide block and the second fixed seat.

[0007] Furthermore, a first motor is installed on the outer wall of the slot seat, one end of the lead screw is fixedly connected to the output end of the first motor, and the first motor is electrically connected to the controller.

[0008] Furthermore, the lower surface of the movable plate is provided with multiple slots, and each slot is rotatably connected to a roller, the bottom of which is in contact with the bottom wall of the slot.

[0009] Furthermore, the pressure measuring component includes a support plate located at the top of the groove and a pressure sensor fixed to the bottom wall of the vertical pipe. The support plate is slidably connected to the groove. Several springs are fixedly connected to the lower surface of the support plate and the bottom wall of the groove. A pressure rod is fixed in the middle of the lower surface of the support plate, and the pressure rod is located at the top of the pressure measuring end of the pressure sensor.

The pressure measuring assembly is located on the upper surface of the rotating plate. During the lifting process, the first motor can only be started when a person stands on the surface of the pressure measuring assembly in the middle of the rotating plate, thereby driving the lifting plate to lift.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0023] like Figures 1-4As shown, a rotary performance lifting mechanism is disclosed, comprising a slot 1, a lifting plate 2, and a scissor folding mechanism 3. The scissor folding mechanism 3 is hinged between the slot 1 and the lifting plate 2. A drive assembly 5 for driving the scissor folding mechanism 3 to fold or unfold is installed inside the slot 1. A guide assembly 7 connected to the scissor folding mechanism 3 is installed on the lower surface of the lifting plate 2. A rotating plate 9 is provided on the upper surface of the lifting plate 2, and a groove 91 is formed in the middle of the upper surface of the rotating plate 9. A through hole 92 is formed in the bottom wall of the groove 91. A vertical tube 10 is fixed in the middle of the upper surface of the lifting plate 2. The vertical tube 10 is rotatably connected to the inner wall of the through hole 92 by a bearing. A pressure measuring assembly 11 is provided inside the vertical tube 10 and the groove 91. A second motor 12 for driving the rotating plate 9 to rotate is installed on the side of the lower surface of the lifting plate 2. A controller is provided inside the slot 1.

[0024] In this embodiment, the controller is an S7-1200CPU 1214C PLC controller, which controls the operation of each motor of the device, and the operating program is written through the controller.

[0025] The drive assembly 5 includes a lead screw 51 rotatably connected to the side wall of the slot seat 1. A movable plate 52 is rotatably connected to the surface of the lead screw 51 by a thread, and the movable plate 52 is slidably connected to the slot seat 1. A first fixed seat 4 is fixed on one side of the inner side wall of the slot seat 1. The bottom ends of the scissor folding mechanism 3 are respectively hinged to the first fixed seat 4 and the movable plate 52. The guide assembly 7 includes a T-shaped guide rail 71 fixed to the lower surface of the lifting plate 2, and a slide seat 72 is slidably connected to the surface of the T-shaped guide rail 71. A second fixed seat 8 is fixed on the other side of the lower surface of the lifting plate 2. The top ends of the scissor folding mechanism 3 are respectively hinged to the slide seat 72 and the second fixed seat 8.

[0026] A first motor 6 is installed on the outer wall of the slot 1. One end of the lead screw 51 is fixedly connected to the output end of the first motor 6. The first motor 6 is electrically connected to the controller.

[0027] When the first motor 6 is started, it drives the lead screw 51 to rotate forward or reverse. The lead screw 51 drives the moving plate 52 to move laterally along the inside of the slot seat 1, thereby driving the bottom end of the scissor folding mechanism 3 to move, so that the scissor folding mechanism 3 unfolds or folds, thereby realizing the lifting plate 2. During the unfolding or folding process of the scissor folding mechanism 3, the top end of the scissor folding mechanism 3 drives the slide seat 72 to move.

[0028] This device uses a mechanical method to achieve lifting, which is safer than hydraulic lifting.

[0029] The lower surface of the movable plate 52 has multiple slots, and each slot is rotatably connected to a roller 53, with the bottom of the roller 53 fitting against the inner bottom wall of the slot seat 1.

[0030] The rollers 53 support the movable plate 52, preventing the weight acting on the movable plate 52 from squeezing the lead screw 51, thus protecting the lead screw 51. In addition, the rollers 53 reduce the friction of the movable plate 52 during movement.

[0031] The pressure measuring assembly 11 includes a support plate 111 located at the top of the inside of the groove 91 and a pressure sensor 115 fixed to the bottom wall of the inner tube 10. The support plate 111 is slidably connected to the groove 91. Several springs 112 are fixedly connected to the lower surface of the support plate 111 and the bottom wall of the groove 91. A pressure rod 113 is fixed in the middle of the lower surface of the support plate 111, and the pressure rod 113 is located at the top of the pressure measuring end of the pressure sensor 115. The pressure sensor 115 is electrically connected to the controller.

[0032] When someone stands on the surface of the support plate 111, the support plate 111 descends along the inner wall of the groove 91. At this time, the pressure rod 113 exerts pressure on the pressure sensor 115, which then feeds the pressure information back to the controller. Only then can the controller control the operation of the first motor 6. If no one is standing on the upper surface of the support plate 111, the spring 112 supports the support plate 111, and the pressure rod 113 does not exert pressure on the pressure sensor 115. In this case, the controller cannot control the operation of the first motor 6. Thus, the lifting plate 2 can only be controlled to rise and fall when the performer stands on the surface of the support plate 111 in the middle of the rotating plate 9.

[0033] The bottom end of the pressure rod 113 is rotatably connected to the pressure plate 114 via a bearing.

[0034] When the pressure rod 113 presses against the pressure sensor 115, the pressure plate 114 contacts the pressure measuring end of the pressure sensor 115. Since the pressure plate 114 is rotatably connected to the pressure rod 113, the pressure plate 114 will not affect the pressure of the pressure sensor 115 when the rotating plate 9 rotates as a whole.

[0035] An external gear ring 14 is fixed on the lower surface of the rotating plate 9. The top output end of the second motor 12 passes through the lifting plate 2 and is fixedly connected to a gear 13. The gear 13 meshes with the external gear ring 14.

[0036] After the second motor 12 drives the gear 13 to rotate, the gear 13 drives the external gear ring 14 to rotate, thereby driving the rotating plate 9 to rotate on the surface of the vertical tube 10, thus realizing the rotation of the stage.

[0037] Working principle: When someone stands on the upper surface of the support plate 111, it means that the artist is standing in the middle of the rotating plate 9. Then the first motor 6 can be started to drive the lead screw 51 to rotate forward or reverse, thereby driving the lifting plate 2 to rise and fall. If no one is standing on the surface of the support plate 111, the pressure sensor 115 cannot detect anyone, so the first motor 6 cannot be controlled by the controller, and the lifting plate 2 cannot be raised and lowered, thus achieving a good protection function.

[0038] The preferred embodiments of this utility model disclosed above are merely illustrative of the present utility model. These preferred embodiments do not exhaustively describe all details, nor do they limit the utility model to any specific implementation. Clearly, many modifications and variations can be made based on the content of this specification. This specification selects and specifically describes these embodiments to better explain the principles and practical applications of this utility model, thereby enabling those skilled in the art to better understand and utilize it. This utility model is limited only by the claims and their full scope and equivalents.
