Stage curtain double-drive differential cooperative lifting device

Abstract

The invention relates to a stage curtain double-drive differential cooperative lifting device. A dual-motor driving structure is introduced, and a dual-motor double rotating shaft structural design isadopted. On the basis of a first driving circuit (9) designed concretely, through driving a first rotating shaft (2) by a first rotating motor (3), on the basis of driving a stage curtain to lift andon the basis of a second driving circuit (10) designed concretely, a second rotating motor (5) is added to drive a second rotating shaft (4), each pull rope (8) is designed, and a positioning rod (6)fixedly disposed on the bottom edge of a stage curtain (1) is drawn; based on the design that the rotating speed of a driving rod on the first rotating motor (3) is smaller than that of a driving rodon the second rotating motor (5), double-side drawing is performed on the top edge and the bottom edge of the stage curtain (1), and the stage curtain lifting speed can be effectively improved.

Description

technical field [0001] The invention relates to a stage curtain double-drive differential cooperative lifting device, which belongs to the technical field of intelligent stage curtains. Background technique [0002] Stage curtain is an indispensable equipment on the stage of various types of theaters, theaters, auditoriums, clubs, studios, etc. It plays a role in decorating the stage and improving the performance effect. Three curtains, eaves curtains, horizontal side curtains, gauze curtains, sky curtains, sound-absorbing curtains, cascading curtains, side curtains, safety and fire prevention curtains, etc. The big curtain is inside the gate of the stage. It is the portal of the stage and the main curtain of the stage. It is mainly used for the opening and closing of the performance at the beginning and end, and sometimes it is also used as a scene. The types of the big curtain include opening and closing, lifting, String curtain type, uniform type, etc. Opening can be in ...

AI Technical Summary

Problems solved by technology

The big curtain is inside the gate of the stage. It is the portal of the stage and the main curtain of the stage. It is mainly used for the opening and closing of the performance at the beginning and end, and sometimes it is also used as a scene. The types of the big curtain include opening and closing, lifting, String curtain type, uniform type, etc. Opening can be in three forms: horizontal opening, butterfly opening, and lifting. The curtain puller is one of the most frequently used equipment on the stage. The existing curtain lifting mechanism is simple. The motor drives the shaft to rotate to realize the winding or releasing of the curtain. The lifting depends entirely on the single drive of the motor. If you want to achieve fast lifting, you can only achieve it by increasing the driving force of the motor, which requires more power consumption
