Multifunctional hoisting bisecting stage act curtain towing mechanism

Abstract

The invention relates to a multifunctional hoisting bisecting stage act curtain towing mechanism comprising a support body, a motor, a speed reducer and a towing wheel. The motor and the speed reducerare fixedly mounted on the support body, and the motor drives the towing wheel to rotate by the speed reducer; an output shaft of the speed reducer is horizontally arranged, and the vertical towing wheel is rotatably mounted on the output shaft; a driven fluted disc clutched by gaining electrons and another driven fluted disc clutched by losing electrons are respectively coaxially fixedly mountedat both sides of the towing wheel, a driving fluted disc clutched by gaining electrons and the output shaft of the speed reducer are fixedly mounted, and a driving fluted disc clutched by losing electrons and a chain wheel which is rotatably mounted at the output shaft end are fixedly mounted. The invention has the advantages of compact structure and smart design, can be mounted at one end of anact curtain guide rail support, not only saves stage floor area, but also can simultaneously take effect along with a hoisting mechanism to realize the variety of the towing mechanism, can realize theautomatic and manual control functions, the automatic tightening function of wire ropes and the high-precision position signal collection and control functions, thereby being the stage act curtain towing mechanism with higher novelty.

Description

technical field [0001] The invention belongs to the field of stage machinery, in particular to a traction device for multifunctional stage lifting and opening curtains. Background technique [0002] The large curtain traction device is one of the most frequently used equipment on the stage. The large curtain body is driven by the traction device from the center of the stage to the left and right or up and down. It is used for stage scene conversion, beautiful and generous, and plays a role in enhancing the artistic atmosphere of the stage effect. Most of the existing large curtain horizontal traction devices use the driving device installed on the stage floor to drive the reel mechanism to wind and reciprocate the steel wire rope to realize the opening and closing of the curtain body. It cannot be used with the curtain body lifting device at the same time, and the curtain body cannot be lifted. At present, there is a traction device that can be installed on the horizontal ...

AI Technical Summary

Problems solved by technology

However, this kind of traction device also has certain disadvantages: first, the traction device uses a geared motor to drive the reel, and when the motor equipment fails to work normally, it cannot be opened and closed manually, and the flexibility of use is poor; Slack is easy to occur during use, resulting in unreliable operation of the curtain body. Although the supporting wheel anti-loosening structure is adopted, it cannot adjust the tension of the wire rope in real time; The nut rope guide frame, relying on the left and right displacement of the rope guide frame and the travel switch to realize the stop control of the geared motor, its displacement accuracy is poor, so the control accuracy and reliability cannot meet the high standard use requirements
