Hydraulic Rotating and Rising Stage Design and Application
This paper mainly introduces the application and design of hydraulic rotating and rising stage (hereinafter referred to as “rotating and rising stage”) which is mainly used to support performances. By analyzing the design principle of the stage and the hierarchical structure features, the paper points out the key design contents and presents a comprehensive overview of the current development of the rotating and rising stage to those who are newly engaged in the design work.
Introduction
The stage is a space for performance. Whether it is a theater, a live performance, or a show, the stage is necessary. Rotating and rising stages are special stages. They are composed of rotating performance area, driving and control systems, lifting columns, and movable bases. With the help of the above-mentioned components, rotating and rising stages have the functions of rotation and lifting, and can realize a variety of excellent performances.
Design principle
The design of rotating and rising stage must be carried out from the perspective of configuration. Generally, the configuration of the rotating and rising stage includes three parts: the stage area, the driving and control systems, and the lifting columns.
Stage area: The stage area includes the stage lifting, lifting devices, rotating system, and rotating platforms. The stage lifting device is generally composed of four sets of lift columns, which are composed of connecting plates and cylinders, to realize the lifting and lowering of the stage platform. The rotating system is composed of a gear box, a prime mover and a rotating thrust bearing, which is used to drive the stage platform to rotate. The rotating platform is composed of support tubes, sidings and guardrails, and is used to provide a stable platform for performing activities.
Drive and control system: The drive and control system generally includes operating mechanism, electronic control system and operating environment. The operating mechanism consists of motor, transmission gear and control button, which is used to drive the motors to work at normal speed. The electronic control system is the core of the whole system. It is responsible for the real-time monitoring of working parameters such as speed, acceleration, and vibration. The operating environment refers to the environment factors such as temperature, humidity, noise, fire prevention and static electricity, which affects the operation of the system.
Lifting columns: The lifting columns are composed of column frames, transmission parts and control panels. The column frames are used to support the stage platform, and the transmission parts are used to drive the stage platform to rise and fall. The control panel is used to adjust the height of the stage platform.
Design content
(1) Choice of lifting system
The design of the lifting system needs to take into account the load capacity and expected size for the stage. The lifting system is the cornerstone for the system design of the rotating and rising stage. The commonly used lifting system includes electric control lifting system, pneumatic control lifting system, oil cylinder lifting system, wire rope lifting system and ratchet lifting system. Generally, electric control and pneumatic control lifting systems should be adopted in case of high load capacity and easy operation.
(2) Choice of drive and control system
The drive and control system is the core of the rotating and rising stage. The drive and control system is the key element to realize the movement of the stage. In the drive and control system, the motor is the key element. The motor should be selected according to its own parameters, such as rated power, rated voltage, frequency and speed. It should also be adapted to the environment in which it is used. At the same time, the installation accuracy of the motor should be in line with the requirements of the lifting system, and the rotation direction of the motor should be in line with the lifting system.
(3) Design of rotating platform
The rotating platform is an important part of the rotating and rising stage. Its design is the key to the overall performance of the stage. Generally, for a small and medium-sized stage, an arc-shaped rotating platform is used, in which the stage platform is the spoke, the drive and control system is the hub, and the driving force is transmitted symmetrically. The supports of the rotating platform should usually be evenly arranged to increase the stability of the stage.
Conclusion
This paper introduces the application and design of hydraulic rotating and rising stage. Through the introduction of its design principle and hierarchical structure features, the key design contents are summarized. On the basis of the summary of facts and the corresponding cases, possibilities and development trends of the rotating and rising stage design have further been discussed.
