Automatic curtain drawing mechanical equipment for stage

Abstract

The invention relates to automatic curtain drawing mechanical equipment for a stage, which comprises a first stand column, a second stand column, a top seat, first curtain drawing devices and a second curtain drawing device, wherein the first stand column and the second stand column are arranged at the left end and the right end of the top seat correspondingly, fixing pins are arranged at the bottom ends of the first stand column and the bottom ends of the second stand column correspondingly, a plurality of first curtain drawing devices are arranged at the bottom of the front end of the top seat, the second curtain drawing device is arranged at the rear end of the top of the right side surface of the first stand column, the left side surface of the second stand column is provided with a third curtain drawing device at the position right opposite to the second curtain drawing device, and a curtain hanging frame is arranged between the second curtain drawing device and the third curtain drawing device. According to the invention, driving wheels and driven wheels of two sets of transmission devices drive a transmission chain to draw the stage curtain from the center of the top seat to the left end and the right end respectively, the curtain drawing and closing speed can be increased, the two sets of transmission devices are directly driven by a servo motor to pull a mechanical box to move, and friction resistance borne by automatic movement of the mechanical box is reduced.

Description

technical field [0001] The present invention relates to the technical field of equipment for curtain-drawing on a stage, in particular to an automatic curtain-drawing mechanical equipment for a stage. Background technique [0002] The curtain device is an indispensable tool in stage performances. The existing stage curtain machine mainly uses the cable to pull the head pulley at the front end, so that it slides on the track, and the subsequent sliding of the secondary pulley mainly depends on the extension of the curtain, thereby driving the secondary pulley to slide. The pulling force on the pulley mainly comes from below, and after using this method for a long time, it will increase the friction between the pulley and the track, which will cause the pulley to be stuck, and also affect the service life of the pulley; now Most of the curtain systems used are manually operated through the cooperation of ropes and pulleys, and the translation operation is performed by pulling...

Problems solved by technology

[0003] The problem to be solved by the present invention is to provide an automatic curtain-drawing mechanical equipment for the stage, which solves the problems that the existing stage curtain-drawing work is cumbersome, and the curtain-drawing error or delay affects the stage effect, so that the stage curtain-drawing equipment can cooperate with the stage. The performance needs to deploy the curtain pulling process to ensure the scientific cooperation between the stage curtain and the stage performance, making the stage performance more multi-element
