Description

Technical Field

[0001] This utility model relates to the field of rotating stage technology, specifically a lifting and rotating stage. Background Technology

[0002] A stage is a space provided in a theater for actors to perform. It allows the audience to focus their attention on the actors' performance and achieve the desired viewing effect. A stage usually consists of one or more platforms, some of which can be raised and lowered. Types of stages include proscenium stages, extended stages, circular stages, and rotating stages.

[0003] For example, the authorization announcement number "CN207122149U" describes a lifting and rotating stage. The scissor-lifting mechanism provides good stability during lifting. The support platform and the support wheels on the support platform provide support for the rotating frame, making the rotation process more stable. However, the existing lifting and rotating stages have a base area that is too small relative to the stage above. This makes the entire lifting and rotating stage appear top-heavy. Since performers need to jump or interact above the lifting and rotating stage, this top-heavy rotating stage structure is very easy to tip over, seriously affecting the safety of the lifting and rotating stage. Utility Model Content

[0004] The purpose of this utility model is to solve the safety problems of existing lifting and rotating stages, and to propose a lifting and rotating stage.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] Design a lifting and rotating stage, including a stage base, a base plate and tiered steps. The stage base is fixedly installed above the base plate. The inner side of the stage base is provided with a stable lifting structure. Multiple tiered steps are fixedly connected to the outer wall of the stage base, and the vertical ends of the multiple tiered steps are connected together.

[0007] Preferably, the stable up-and-down lifting structure includes hydraulic cylinders and guide columns. Multiple guide columns are fixedly installed at the inner bottom of the stage base. Limiting hoops are slidably connected to the outer sides of multiple guide columns. Multiple hydraulic cylinders are fixedly installed on the inner bottom surface of the stage base. Support plates are fixedly connected to the top of multiple hydraulic cylinders. A reserved cavity is fixedly opened inside the limiting hoops.

[0008] Preferably, a stage rotating structure is provided above the plurality of support plates. The stage rotating structure includes a fixed plate and a rotating plate. The fixed plate is fixedly installed on the top of the plurality of support plates. A servo motor is fixedly installed at the lower end of the fixed plate. A reducer is fixedly connected to the output shaft of the servo motor. The other end of the output shaft of the reducer is fixedly connected to the rotating plate. A weight-reducing groove is fixedly opened on the inner side of the rotating plate. A sound-absorbing layer is fixedly connected to the inner side of the rotating plate.

[0009] Preferably, a covering cloth is fixedly connected to the outer wall of the rotating plate, and the edge of the covering cloth is movably connected to the inner wall of the stage base.

[0010] Preferably, the multiple guide columns are distributed equidistantly along the outer side of the central fixed plate, and the multiple hydraulic cylinders are distributed parallel to each other equidistantly along the circumference.

[0011] Preferably, the top end of the limiting hoop is fixedly connected to the lower edge of the fixing plate.

[0012] The present invention proposes a lifting and rotating stage, which has the following advantages: the hydraulic cylinder provides hydraulic force to drive the upper support plate to rise, and the support plate will push the rotating plate of the upper stage to a designated height for performance. When the support plate falls, the height of the reserved cavity is flush with the height of the hydraulic cylinder base, which facilitates the storage of the rotating plate inside the stage. The large area at the bottom forms a relatively stable support. The overall stage structure is small at the top and large at the bottom. Moreover, the lifting and lowering process has auxiliary positioning, which effectively improves the safety of the lifting and rotating stage. Attached Figure Description

[0033] The guide column 45 can guide the limiting hoop 44 to slide up and down along a fixed trajectory. Multiple hydraulic cylinders 41 are provided. The hydraulic cylinders 41 provide hydraulic power to drive the upper support plate 42 to rise. The support plate 42 will push the rotating plate 56 of the upper stage to a specified height for performance. When the support plate 42 falls, the height of the reserved cavity 43 is flush with the height of the base of the hydraulic cylinder 41, which makes it convenient for the rotating plate 56 inside the stage to be stored. The large area at the lower end forms a relatively stable support.

[0034] The rotating structure of a rising and rotating stage:

[0035] The fixed plate 51 is fixedly installed on the top of multiple support plates 42. When a rotational performance is required, the power supply is connected to start the servo motor 52. After the output shaft of the servo motor 52 is reduced in speed by the reducer 53, it drives the rotating plate 56 connected to the fixed plate 51 by bearings to rotate slowly. The rotating plate 56 will rotate and drive the performers to rotate. The weight reduction groove 54 adopts multiple through holes with internal hollowing. The weight reduction groove 54 can reduce the weight of the rotating plate 56 and improve the stability of the stage. The sound absorption layer 55 is made of foam sponge, which can effectively absorb and reduce the noise generated by large movements on the stage.
