Description

[0001] The present invention relates to a wire rope disk drum for a stage device,

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wire rope disc drum for a stage apparatus, and more particularly, to a wire rope disc drum for a stage apparatus, which comprises a reinforcing plate A wire for a stage device capable of preventing the phenomenon of wire rope being pushed when the wire rope is operated and operating the wire rope in a balanced state to improve the operability and the safety of the product, To a rope disk drum.

In general, a wire rope disk drum for a stage device is a drum for guiding the smooth operation of a running stage, a banner, a lighting, and various background films, that is, a wire rope connected to a set during a rise or fall of various sets, A drum for a plurality of lines having a plurality of guide grooves for guiding a plurality of wire ropes to a drum and a drum for a line having a guide groove for guiding a wire rope in one drum, A plurality of drums are used for raising or lowering the set water.

Particularly, in the stage apparatus, the wire drum is used when the film is lifted or lowered and is positioned at a predetermined position of the stage space only when necessary, and when it is not necessary, the wire drum is lifted up to hide it in the space above the stage, When the wire rope is wound on the drum, the stage device is raised. When the wire rope is loosened, the wire rope is lowered by the weight of the stage device, and the wire rope is moved to the desired position Position.

As shown in Figs. 1 and 2,

Looking at the configuration of a typical stage device,

A wire rope 20 connected to a plurality of points of the work hanging table 10 to move the work hanging table 10 upward and downward, A rotary sheave 30 provided on the upper surface of the grid frame 50 to change the traveling direction of the rope 20 and a rotary sheave 30 for winding the wire rope 20 to selectively move the elevator 10 up and down. And a driving unit 40 installed at one side of the frame 50. The driving unit 40 includes an aluminum wire drum 41 provided to wind or unwind the wire rope 20, A speed reducer 42 connected to the rotation shaft of the drum 41 and connected to a motor 43 to be described later to reduce the rotational speed of the motor 43 to transmit the driving force to the drum 41 side, ) And is supplied with power And a motor 43 for driving the aluminum wire drum 41 to rotate.

The construction of the above-described wire drum will be briefly described as follows.

A bobbin coupled between the drum plate and the drum plate and having a wire wound around the outer periphery thereof; and a fastening member for fastening the drum plate and the drum plate to each other, .

Here, in winding the wire rope by fixing one end of the wire, the end of the wire rope is passed through the wire inlet hole formed in the bobbin and the drum plate and then simply bundled or the wire rope end is fastened The wire rope to be wound up as described above has a disadvantage in that the binding portion is released due to the continuous wire rope action and thus the wire rope is liable to fall. In addition, due to the phenomenon that the wire rope tilts to one side of the wire drum, The drum plate and the drum plate are widened and the winding and unwinding operation of the wire rope is not smoothly performed.
