Lifting stage remotely controlled by PLC

Abstract

The invention discloses a lifting stage remotely controlled by a PLC. The lifting stage comprises a main stage, a lifting sub-stage, a hydraulic lifting device, a hydraulic station, a controller and an upper computer, wherein the lifting sub-stage is arranged at an opening of the main stage; the hydraulic lifting device is located under the lifting sub-stage, and the hydraulic lifting device is composed of a base fixed at the bottom end of the main stage, a first scissor-shaped frame set, a second scissor-shaped frame set, a third scissor-shaped frame set, a first cross beam, a second cross beam and a hydraulic oil cylinder; and the hydraulic station is composed of a hydraulic pump, an oil pipe, a motor for driving, an oil tank, an overflow valve, a solenoid directional control valve and aflow adjusting electromagnetic valve, and an outlet of the overflow valve communicates with the oil tank. The lifting stage has the advantages of being simple in structure and high in practicability.

Description

technical field [0001] The invention relates to the technical field of stage equipment, in particular to a PLC remote control liftable hydraulic stage. Background technique [0002] The stage is the space provided for the actors to perform in the theater. It can make the audience focus on the actors' performance and obtain the ideal viewing effect.

With the continuous development and innovation of science and technology, the stage equipment is also developing rapidly, so as to obtain more A good performance effect can not only create an appropriate dramatic environment for the repertoire, but more importantly, it can turn the short moment in the theater into eternity in the audience's mind. It is the appearance and development of the stage scenery that expands the music The performance space of the play vividly strengthens the contrast between time and space, so that all stage activities and scenes of the musical can be carried out smoothly. Some stages of the existing stage equipment are only fixed on the ground, and the stage cannot be raised and lowered. The stage can only be controlled in the near field, and the ups and downs of the stage cannot be controlled remotely, which affects the performance effect
