Stage curtain single-driving cooperation double-power lifting device

Abstract

The invention relates to a stage curtain single-driving cooperation double-power lifting device. A single-motor driving structure is introduced, an existing rotating motor (3) drives a first rotatingshaft (2) to drive a stage curtain to lift, a second rotating shaft (4) is introduced, a driving gear (5) and a driven gear (6) are arranged at the end of the first rotating shaft (2) and the end of the second rotating shaft (4) and occluded each other and rotatably work, rotation of the first rotating shaft (2) drives the second rotating shaft (4) to rotate, pull ropes (8) are designed, tractionis achieved according to positioning rods (7) fixedly arranged at the bottom side of the stage curtain (1), the outer diameter of the driving gear (5) is larger than that of the driven gear (6), double-side traction is achieved for the top side and the bottom side of the stage curtain (1), and lifting of the stage curtain can be effectively accelerated.

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
