Description

Rope coupler

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a rope connecting device, and more particularly, to a rope connecting device capable of quickly and easily connecting various ropes used in various facilities of various industrial fields and strongly connecting a connecting portion.

Ceiling crane is used as a device to lift and carry various kinds of heavy goods in various industrial fields. A ceiling crane consists of a traveling device, a hoisting device, a wire drum, a pulley, a sheave, a wire rope, and a hook. At this time, since the wire rope is used over a long period of time, various kinds of damage may occur. For example, strands or deep seams of wire rope can be damaged locally by corrosion, depression, deviations, protrusion, compression, swelling, plus kink and minus kink.

Carrying heavy objects by a ceiling crane is carried out at a height of several meters to several tens of meters high, so if a wire rope is damaged and broken, it can lead to a major accident such as a fall of a heavy object. Therefore, the wire rope is replaced at a predetermined time and is kept in a state of always available.

A wire rope wound on a wire drum, for example, a first wire rope is loosened, a hook is placed on the ground, a first wire rope on a hook side is ground and cut, and a new wire rope, for example, And then the second wire rope is moved to the wire drum position by winding the first wire rope with the wire drum to cut the joint surface of the first wire rope and the second wire rope, The first wire rope is loosened from the wire drum to the ground, the second wire rope is fastened to the wire drum, then wrapped, and the end of the second wire rope is assembled to the hook The wire rope was changed in a series of processes.

At this time, the process of connecting the second wire rope to the cut surface of the first wire rope by welding or the like on the ground is a process requiring a considerable working time of about 90 minutes even though it is performed by a skilled worker. Furthermore, the work time may be further delayed depending on the skill of the operator. In addition, if the welding is not properly performed in this process, the joint surface of the first wire rope and the second wire rope may pass through the plurality of pulleys and sheaves in the course of hoisting the first wire rope, leading to a large accident .
