In the cranes disclosed in Japanese Utility Model Application Publication No. 54-139466 and Japanese Patent Application Publication No. 56-70291, wire ropes are replaced as follows. Normally,
The end of the new rope is welded to the end of the old rope, and the old rope is used in place of the messenger rope for rope replacement. Or remove the old rope completely,
A new thin metsenjar rope was installed, and this rope was used to install the new rope. When this old rope was used, the twist of the old rope was transferred directly to the new rope, which caused the hanging tool to become twisted after the rope was replaced, requiring a large amount of time to remove the twist. Also, the work required to change the rope to a thinner one is 2 times longer than when using the old rope as the rope.
It required twice as much time.

An object of the present invention is to provide a work tool that allows wire ropes to be replaced efficiently in a short time and without causing problems such as twisting of the hanging tool after installation.

The present invention provides a metal fitting that is driven into the end of the old rope and the end of the new rope to connect the two, and the metal fitting is provided with a rotating part.

The present invention will be explained below with reference to an example shown in the drawings. Reference numeral 1 designates a biting joint that is driven into and fixed to the end of the rope, and has a plurality of driving claws 2 provided on a circumference having a diameter larger than the outer diameter of the wire rope. 3
is the joint rope, 4 is the male side of the rotary joint, and 5 is the female side of the rotary joint. These are sequentially connected in series as shown in the figure.

継手１には新ロープの端部を差込んで打込み爪２
を打込み、固定する。 In this configuration, when replacing the rope, the end of the old rope is inserted into one of the biting joints 1, and the driving pawl 2 is driven in and fixed. Insert the end of the new rope into the biting joint 1 at the other end, and
Drive in and fix.
かかる構成によれば、旧ロープの寄りは回転継

るものである。 According to this configuration, the deviation of the old rope is absorbed by the rotary joints 4 and 5, and is not transmitted to the new rope. In addition, the connection to the new and old ropes is also possible using the driving claw 2.
This method is extremely easy to perform.

ーロープの径よりも大きいので、ワイヤーロープ
と食込み継手１との接続作業において食込み継手
１内へのワイヤーロープの挿入を容易に行うこと
ができるものである。 In addition, since the diameter of the plurality of driving claws 2 is larger than the diameter of the wire rope, the wire rope can be easily inserted into the biting joint 1 during the connection work between the wire rope and the biting joint 1. It is.

過も容易に行われ、脱落がなく、交換作業を容易
に行えるものである。 After connecting the old rope and the new rope using such a connecting device, if the old rope is pulled, the new rope is pulled and the new rope is tensioned on the crane. At this time, since the joint ropes 3, 3 are used as the connectors so that they can be easily bent, the sheave of the crane can easily pass through, and there is no chance of the sheave falling off, making it easy to replace the sheave.

である。 Further, when the rope is moved during the replacement operation, the rope is bent in multiple directions by each sheave. Since the plurality of driving claws 2 are arranged circumferentially, there are a plurality of connection parts between the driving claws 2 and the wire rope. Therefore, even if the wire rope is moved during replacement work, the wire rope and the biting joint 1 will not become disconnected from each other.

According to the present invention, in addition to being able to use the old wire rope as a messenger rope, the twist of the old wire rope is not transferred to the new wire rope, which reduces the cost of replacing the wire rope and prevents twisting of the hanging device after installation. It has the effect of preventing defects, and since multiple driving claws are provided in a circumference larger than the diameter of the wire rope and joint ropes are used in some parts, the passage of the sheave is performed easily and reliably. This allows for easy replacement work.
