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 ...

Embodiment Construction

[0026] The present invention will be described in further detail below in conjunction with the examples. The following examples are only descriptive, not restrictive, and cannot limit the protection scope of the present invention with this.

[0027] A multi-functional stage lifting device for the large curtain, which is composed of a frame body 4, a motor 14, a reducer 15, and a traction wheel 8. The motor and the reducer are fixed at the lower end of the frame body, and the output shaft 11 of the reducer is a horizontal output. On the output shaft, the longitudinal traction sheave is installed through bearing rotation. In order to ensure the bearing capacity, the traction sheave adopts the form of double grooved sheave. The left and right sides of this traction sheave are coaxially fixed respectively the follower chainring of electric clutch 13 and de-energized clutch 9. Simultaneously, the driving chainring of the electric clutch is fixedly installed with the output shaft of...
