Description

[0001] Multifunction drive machine [0002]

The present invention relates to a multifunctional driving device which is easy to use in a modular form at various positions such as a ceiling, a floor or a side of a stage, and supports at least two points at the same time so as to easily install and use additional installations without shaking.

Generally, the way of driving the stage is to connect the wire to the barton supporting the set of stage and to unwind or rewind the wire to provide the desired installation naturally. In order to ascend and descend such a wire, a method of moving the drum in a longitudinal direction by fixing one end of each wire to the screw drum and then winding or unwinding is used. As the number of windings increases, And a classic method using fixed drums and fixed pulleys is also used.

The drum movement method in which the drum moves in the axial direction while rotating is described in Korean Patent Registration No. 10-1041445, Korean Utility Model Registration No. 20-0464796, and Korean Patent Registration No. 10-1678551. The drum is rotated only, The pulley movement method for guiding the wire winding or pulling is known as a domestic patent registration No. 10-1451751.

In addition, the Korean patent registration No. 10-1005712 has been developed to supply the wire from both sides of the outer diameter of the drum, and to simultaneously unwind and wind it simultaneously. However, since the wire is required to be supplied to the drum at a narrow interval, . Also, since the drum is not a screw drum but a disc drum type, the diameter of the wound wire becomes larger as the wire is wound on the surface of the disc drum, and as the wire is loosened, the diameter becomes smaller and it is difficult to raise and lower the wire at a constant speed.

In addition, although a method of supplying wires to both sides of the outer diameter of the drum has been developed as a domestic patent registration No. 10-1678551, it is difficult to apply it to a stage driving apparatus which does not use a weight and which is specialized in a stage driving apparatus using a weight. There is a problem in that it can be used only in a weighting method in which rising and falling are necessary at the same time.
