Description

Cable anti-twist pooling machine}

The present invention relates to a cable twist-preventing pulling machine, and more particularly, to a cable twist-preventing pulling machine for preventing cable breakage by preventing the cable from being twisted by a connection hook when connecting a handle and a cable.

In general, high-altitude lighting is installed on the ceiling surface of buildings such as factories and gymnasiums to illuminate the interior, and the grill of an air conditioner is fixed to the ceiling surface to discharge cold and hot air generated from the air conditioner into the room. It is located at the bottom of the main body to suck indoor air, and the stage lighting batten is designed to be installed and used with lights and banners used in various stage performance halls such as plays, dances, and operas.

The high-altitude lighting, air conditioner grille, and stage lighting battens (hereinafter referred to as 'elevating items') are used for different purposes, but all of these products are installed and used on the ceiling surface of a building. Therefore, when using elevating items for a long period of time, cleaning and exchanging work is performed periodically because the service life ends or dust accumulates. As a means to make cleaning and exchanging work simple and safe, it is installed in the lifting device that lowers the elevating items to the ground. used

In this way, looking at the structure of the elevating and descending device for elevating and descending the high-altitude lighting, the grill of the air conditioner, and the stage lighting batten, a main body installed and fixed on the ceiling surface, a drum installed inside the main body and rotated forward and reverse by a driving motor , One end is connected to the drum and the other end is composed of a wire that raises or lowers the elevating body while being wound or unwound on the drum in a state connected to the elevating body.

Although there is an advantage in that an elevating item can be raised or lowered using the conventional elevating device as described above, conventionally, the wire is twisted in an “S” shape or “Z” shape for strength, so the wire is When it is unwound or wound on the drum, it has the property of self-rotating in the twisted direction.

Therefore, when the conventional wire is wound or unwound on the drum, the wire itself rotates in the twisted direction, so if the twist is not unwound, the elevating item connected to the lower end of the elevating body rotates, resulting in a risk of accident, and the wire itself rotates in the reverse direction. There were disadvantages such as damage to the wire while twisting and shortening the product life.
