Stage lifting method for lifting and lowering performer and performing tool in balanced mode

Abstract

The invention discloses a stage lifting method for lifting and lowering a performer and performing tools in a balanced mode. The method is characterized in that the performer and tools related to performance are placed on the upper end surface of an upper supporting base; an electromotor runs, power is transmitted to a threaded rod through a power transmission mechanism, and the threaded rod axially rotates around the own body under the effect of power provided by the electromotor; the threaded rod axially rotates around the own body and drives a driving block to axially make movements close to a fixed block along the threaded rod, therefore a lifting device is switched to a stretching state from a contraction state, and the performer is lifted to the highest point; after the lifting stageis used, the electromotor runs reversely and makes the threaded rod rotate reversely, therefore the lifting device is switched to the stretching state from the contraction state, the upper supportingbase can recover to the original state, and the lifting stage can recover to the original state.

Description

technical field [0001] The invention relates to a lifting method for a balanced lifting stage. Background technique [0002] With the rapid development of society, the stage has become more and more important, whether it is a wedding, or business activities, and various cultural performances in schools and so on. All need to use the stage, so the stable lifting of the stage becomes very important. The traditional stage basically adopts hydraulic lifting or folding bracket lifting directly, so the lifting cannot accurately control the lifting range and for the hydraulic device or the folding bracket is damaged. The protection is not in place, and at the same time, the transmission may not be stable when lifting. Contents of the invention [0003] In order to solve the deficiencies of the prior art, the object of the present invention is to provide a lifting method for a balanced lifting stage to solve the problems mentioned in the background above. There are four sets of ...
