Abstract
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 ...
Examples
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...
