Description

Lifting rotary stage Technical Field The utility model relates to the technical field of revolving stages, in particular to a lifting revolving stage. Background The stage is a space provided for the actor's performance in the theatre, which can concentrate the audience's attention to the actor's performance and obtain the ideal ornamental effect, and is generally composed of one or more platforms, some of which can be lifted and lowered, and the types of the stage are a frame type stage, an extension type stage, a ring type stage and a rotary type stage ‌ ‌ ‌. For example, the authorized bulletin number CN207122149U is named as a lifting revolving stage, the scissor type lifting mechanism has good lifting stability, and the supporting tables and the supporting wheels on the bearing table have supporting functions on the rotating frame, so that the rotating process of the rotating frame is more stable, but the existing lifting revolving stage has too small area of the base relative to the upper stage, thus the whole lifting revolving stage is light in weight, because the performer needs to jump or interact above the lifting revolving stage, the structure of the revolving stage with light weight is easy to topple, and the use safety of the lifting revolving stage is seriously affected. Disclosure of utility model The utility model aims to solve the problem that the use of the existing lifting revolving stage is unsafe, and provides a lifting revolving stage. In order to achieve the above purpose, the present utility model provides the following technical solutions: The utility model provides a lift revolving stage, includes stage base, bottom plate and classifying step, stage base fixed mounting is in the top of bottom plate, stage base's inboard is equipped with stable oscilaltion structure, and is a plurality of classifying step fixed connection is on stage base's outer wall, a plurality of classifying step's vertical end to end. Preferably, the stable up-down lifting structure comprises a hydraulic cylinder and guide posts, wherein a plurality of guide posts are fixedly arranged at the bottom end of the stage base, a plurality of guide posts are slidably connected with limiting hoops at the outer sides of the guide posts, a plurality of hydraulic cylinders are fixedly arranged on the bottom surface of the inner wall of the stage base, a plurality of hydraulic cylinders are fixedly connected with supporting plates at the top ends of the hydraulic cylinders, and reserved cavities are fixedly arranged in the limiting hoops. Preferably, a plurality of the top of backup pad is equipped with stage revolution mechanic, stage revolution mechanic includes fixed plate and rotor plate, fixed plate fixed mounting is on the top of a plurality of backup pads, the lower extreme fixed mounting of fixed plate has servo motor, servo motor's output shaft fixedly connected with reduction gear, the output shaft other end fixedly connected with rotor plate of reduction gear, the inboard fixed heavy groove of having seted up of rotor plate, the inboard fixedly connected with amortization layer of rotor plate. Preferably, the outer wall fixedly connected with of rotor plate covers cloth, cover cloth's edge and the inner wall activity of stage base link to each other. Preferably, a plurality of guide posts are distributed at equal intervals along the circumference of the outer side of the central fixing plate, and a plurality of hydraulic cylinders are distributed in parallel along the circumference at equal intervals. Preferably, the top end of the limit hoop is fixedly connected with the edge of the lower end of the fixing plate. The lifting revolving stage has the beneficial effects that the hydraulic cylinder provides the pushing force to drive the upper supporting plate to ascend through the hydraulic pressure, the supporting plate can push the rotating plate of the upper stage to ascend to the designated height so as to facilitate performance, when the supporting plate falls down, the height of the reserved cavity is flush with the height of the base of the hydraulic cylinder, so that the rotating plate on the inner side of the stage is convenient to store, a relatively stable support is formed by using a large lower end area, then the upper part of the whole stage structure is small, the lower end is large, and the lifting process has auxiliary positioning, so that the use safety of the lifting revolving stage is effectively improved.
