Abstract

The invention discloses a stage lifting platform. The stage lifting platform comprises a lifting platform frame, supporting frames, a power device and a counterweight device, wherein the supporting frames are located on the two sides of the lifting platform frame and fixedly arranged on a base plane, guide rails are arranged on the supporting frames, the lifting platform frame is arranged on the guide rails of the supporting frames in a sliding mode through sliding blocks, the balance weight device comprises a balance weight support and a balancing weight arranged on the balance weight support in a sliding mode, the lifting platform frame is connected with the power device through a chain transmission mechanism, the balancing weight is connected to the lifting platform frame through a steel wire rope, and when the lifting platform frame is in an ascending state, the balancing weight is in a descending state. According to the stage lifting platform, a driving motor drives the stage to ascend and descend through chains, compared with a shear fork type driving mode, the chain driving mode is high in precision and safer, the use requirements in severe environments such as a wet deep foundation pit are particularly met, a high-quality and reliable transmission mode can be provided, and the performance effect of the stage is effectively improved.

Description

technical field [0001] The invention relates to the technical field of mechanical performance stages, in particular to a stage lifting platform. Background technique [0002] The stage lifting platform is an indispensable mechanical equipment in the modern theater. The lifting platform can be used to switch the scene of the performance and move the scenery and actors up and down. Most of the existing lifting platforms adopt hydraulic or scissor-fork transmission structure, which has low transmission efficiency, is greatly affected by temperature changes during work, has high noise, hydraulic components are sensitive to pollution, and has low precision and poor reliability. Contents of the invention [0003] The purpose of the present invention is to address the above deficiencies and provide a stage lift platform based on chain transmission, which improves transmission efficiency, reduces operating noise, and improves overall operating stability. [0004] The technical sc...
