这种升降舞台通过牵引绳的牵拉升降,安全性降低,一旦坠落容易造成演出事故
[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: When the device is in use, the motor starts and controls the worm gear to rotate. Since the worm gear meshes with the worm wheel, the worm gear drives the worm wheel to rotate, and the worm wheel drives the slot to rotate. Since the slot is located in the slot and slides in contact with the swing arm, the actuating rod drives the swing arm to swing through the slot. That is, the other end of the swing arm drives the lifting plate to rise and fall through the connecting rod. The lifting plate then drives the lifting platform to rise and fall through the support column to adjust the stage plane. At the same time, when the slider accelerates down, due to the increased speed of the slider, when the limiting rod moves past the fixed rod, the rotating plate touches the next fixed rod before it returns to the vertical state due to gravity, causing the rotating plate to tend to be horizontal. Then, the limiting plate limits the horizontal rotating plate and locks it, that is, the slider is locked to prevent the lifting plate from falling, thereby improving safety.

Abstract
Description
Technical Field
[0001] This utility model relates to the field of lifting stages, specifically a planar fine-tuning device for lifting stages. Background Technology
[0002] The lifting stage is the most commonly used stage product, primarily used for moving scenery and actors up and down during scene transitions. Additionally, to highlight the main actors, the stage can slowly rise, allowing them to dance gracefully and creating dynamic visual effects. The rising and falling motion also enhances the performance. Previously, stages were generally fixed structures with a platform that could not be raised or lowered. This type of stage structure limited program arrangement and performance, especially in achieving diverse three-dimensional effects. With the continuous improvement of people's material and cultural living standards, their demands for artistic taste have also increased. As stage choreography has become more sophisticated, there have been innovative requirements for stage structure and function, leading to the development of the lifting stage. However, this type of lifting stage, which is raised and lowered by traction ropes, has reduced safety; a fall could easily cause performance accidents.
[0003] The present invention aims to solve the technical problems existing in the prior art. To this end, a planar fine-tuning device for lifting stage is proposed. Utility Model Content
[0004] The purpose of this invention is to provide a planar fine-tuning device for a lifting stage to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution:
[0006] A planar fine-tuning device for a lifting stage includes a stage, a control box on the stage, a drive mechanism fixedly connected to the stage, and a transmission mechanism rotatably connected to the stage, with the drive mechanism meshing with the transmission mechanism;
[0007] The stage is rotatably connected to a lifting device, which cooperates with a transmission mechanism. A fall protection component is fixedly connected to one side of the lifting device. The stage is fixedly connected to a guide rail body, and the fall protection component cooperates with the guide rail body.
[0008] As a further embodiment of this utility model: the driving mechanism includes a motor, which is fixedly connected to the stage, and a worm gear is fixedly connected to one side of the motor, which meshes with the transmission mechanism.
[0009] As a further embodiment of this utility model: the transmission mechanism includes a worm gear, which is rotatably connected to the stage, and a lever is fixedly connected to one end of the worm gear, which cooperates with the lifting device.
[0010] As a further embodiment of this utility model: the lifting device includes a swing arm and a lifting plate. The swing arm is rotatably connected to the stage. A slot is provided inside the swing arm. One end of the drive rod extends into the slot and slides in contact with the swing arm. A connecting rod is fixedly connected to one side of the lifting plate. The lifting plate is rotatably connected to the swing arm through the connecting rod. An anti-fall component is fixedly connected to one side of the lifting plate. A support column is fixedly connected to one end of the lifting plate, and a lifting platform is fixedly connected to the other end of the support column.
[0011] As a further embodiment of this utility model: the fall prevention device includes a slider, which slides in contact with the guide rail body. A rotating plate is rotatably connected inside the slider. A limiting plate is fixedly connected inside the slider. The limiting plate is used to limit the rotation plate. A limiting rod is rotatably connected to the rotation plate. The limiting rod cooperates with the guide rail body.
[0012] As a further embodiment of this utility model: the guide rail body includes a guide rail, which is fixedly connected to the stage and vertically slidably connected to the slider. Several fixed rods are provided in the guide rail, and the fixed rods are matched with the rotating plate.
[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: When the device is in use, the motor starts and controls the worm gear to rotate. Since the worm gear meshes with the worm wheel, the worm gear drives the worm wheel to rotate, and the worm wheel drives the slot to rotate. Since the slot is located in the slot and slides in contact with the swing arm, the actuating rod drives the swing arm to swing through the slot. That is, the other end of the swing arm drives the lifting plate to rise and fall through the connecting rod. The lifting plate then drives the lifting platform to rise and fall through the support column to adjust the stage plane. At the same time, when the slider accelerates down, due to the increased speed of the slider, when the limiting rod moves past the fixed rod, the rotating plate touches the next fixed rod before it returns to the vertical state due to gravity, causing the rotating plate to tend to be horizontal. Then, the limiting plate limits the horizontal rotating plate and locks it, that is, the slider is locked to prevent the lifting plate from falling, thereby improving safety.

[0021] The stage 1 is rotatably connected to a lifting device, which cooperates with a transmission mechanism. A fall protection component is fixedly connected to one side of the lifting device. The stage 1 is fixedly connected to a guide rail body, and the fall protection component cooperates with the guide rail body.
[0022] Please see Figure 1-3 The drive mechanism includes a motor 12, which is fixedly connected to the stage 1. A worm gear 11 is fixedly connected to one side of the motor 12, and the worm gear 11 meshes with the transmission mechanism.
[0023] Please see Figure 1-3 The transmission mechanism includes a worm gear 7, which is rotatably connected to the stage 1. One end of the worm gear 7 is fixedly connected to a lever 9, which cooperates with the lifting device.
[0024] Please see Figure 1-3The lifting device includes a swing arm 8 and a lifting plate 4. The swing arm 8 is rotatably connected to the stage 1. A slot 10 is provided inside the swing arm 8. One end of the drive rod extends into the slot 10 and slides in contact with the swing arm 8. A connecting rod 5 is fixedly connected to one side of the lifting plate 4. The lifting plate 4 is rotatably connected to the swing arm 8 through the connecting rod 5. An anti-fall component is fixedly connected to one side of the lifting plate 4. A support column 3 is fixedly connected to one end of the lifting plate 4, and a lifting platform 6 is fixedly connected to the other end of the support column 3.
[0025] Please see Figure 1-3 The fall protection device includes a slider 14, which slides in contact with the guide rail body. A rotating plate 16 is rotatably connected inside the slider 14.

[0027] The working principle of this utility model is as follows: When the device is in use, the motor 12 starts and controls the worm gear 11 to rotate.

At the same time, when the slider 14 accelerates down, as the slider 14 speed increases, when the limiting rod 17 moves past the fixed rod 18, the rotating plate 16 touches the next fixed rod 18 before it returns to the vertical state due to gravity, causing the rotating plate 16 to tend to be horizontal. Then, the limiting plate 15 limits the horizontal rotating plate 16 to lock the rotating plate 16, that is, the slider 14 is locked to prevent the lifting plate 4 from falling, thereby improving safety.
