Description

Wire winding apparatus for stage setting

The present invention relates to a wire winding device for stage equipment, and more particularly, to connect the wire to the actor or the stage equipment in a performance stage, and to produce a more compact wire winding device used to move the actor or stage equipment by winding the wire However, it is very simple and convenient to assemble and disassemble when manufacturing the wire winding device itself or performing some repairs due to some breakdown, and responds to the thickness of the wire changed by tension and abrasion when used for a long time. By the idle roller to adjust the pressure applied to the wire wound on the drum, as well as to the wire winding device for the stage equipment invented to be used to move conveniently as needed.

In general, a light bridge for mounting a luminaire, a flying batten for transporting stage equipment, and a point hoist are installed at an upper part of a performance stage.

In the above, the flying barton is installed horizontally on the upper stage, and is a facility for raising and lowering various stage devices, lighting equipment, curtain devices, screens, and the like. Can be lifted and lowered and used to transport the stage equipment in combination with the set barton.

Wire and wire winding device is mainly used for the transfer of such various stage equipment.

1 is a view for explaining the equipment transfer operation of the point hoist using a wire and a conventional wire winding device, according to which the point hoist is a housing 10, a pair of fixed pulleys (16) mounted to the housing 10 ), Located between the pair of fixed pulleys 16 and spaced apart in the direction of the ground, and includes a movable pulley 18 and a wire 14 on which the hook 20 is mounted.

In this case, the hoist movement wheel 12 is mounted on the upper end of the housing 10, and the hoist movement wheel 12 is moved along the rail 24 in a state supported by the rail 24 positioned on the stage. Thus, the housing 10 is moved along the extending direction of the rail 24.

In addition, one end of the wire 14 is sequentially caught by a pair of fixed pulleys 16 through the moving pulley 18, and then through a guide pulley 26 mounted on one end of the rail 24, It is wound around a wire winding device consisting of a motor 28 and a drum 30, and the other end of the wire 14 is fixed to the end of the rail 24.

In such a general point hoist, when the motor 28 constituting the wire winding device rotates, the drum 30 connected to the motor 28 rotates, and the wire 14 is wound around the drum 30 to move. The pulley 18 is moved upward.

As shown in FIG. 2, the conventional wire winding apparatus reduces the rotational speed of the motor 28 in addition to the motor 28 and the drum 30 to increase the driving torque of the drum 30. And two wires 14a and 14b may be respectively configured to be wound at predetermined positions of the drum 30. In this case, the positions at which the two wires 14a and 14b flow into the drum 30 may be provided. It is determined by the position of the pair of wire guide pulleys 26a and 26b.

That is, the two wires 14a and 14b respectively flow into the drum 30 via the pair of wire guide pulleys 26a and 26b, and when the drum 30 rotates according to the rotation of the motor 28, respectively, Wires 14a and 14b are spirally wound by being fitted into a wire insertion groove formed in a spiral shape on the drum 30 surface.

However, in the conventional wire winding device having such a configuration, as the drum 30 rotates once, the winding positions of the wires 14a and 14b wound in the wire insertion grooves of the drum 30 are formed in the spiral wire insertion grooves. Since the position of the wire guide pulleys 26a and 26b for moving the wires 14a and 14b into the drum 30 is fixed while moving in the advancing direction by the drum pitch, the wires 14a, The entry angle of 14b) gradually increases. In general, heavy stage equipment is connected to the wires 14a and 14b, and thus a very large force is applied. Therefore, when the entrance angle of the wires 14a and 14b increases, the wires 14a and 14b are separated from the wire insertion grooves, or the wires 14a are , 14b) may not be wound properly on the drum 30, resulting in a large accident.

In addition, since the motor, the reducer, and the drum that make up the wire winding device are directly connected, the volume, length, and size of the wire winding device are very large and long, so that it is difficult to carry and install. In addition, no device is installed around the drum to allow the wire to be wound to the drum at a certain pressure. In addition, if the wire is used for a long period of time, the wire is stretched or worn out, and the diameter thereof is reduced. Despite the change in the winding force of the wire, there is a problem in that the pressure of the wire wound on the drum cannot be actively controlled.
