Description

The present invention relates to a wire rope twisting machine that eliminates twisting (twisting, kink) generated in a wire rope and enables repeated use.

Conventionally, a dedicated wire rope for wire extension work has been used in the construction of replacing transmission lines between towers. This wire rope is twisted (twisted or kinked) after being used several times and cannot be used as it is, but can be regenerated by removing the twist. However, in order to remove the twist, there is only a method of gradually returning it to the original state by hand, which requires a large area and a lot of human hands, and takes time. For this reason, most construction contractors discard the twisted wire rope and purchase a new one, which lacks resource saving and causes an increase in cost burden.
On the other hand, for example, Patent Document 1 discloses that when a wire drawing wire (wire rope) bundle wound around a drum is attached to a wire drawing drum gantry device and the drum gantry device is fed out as a wire supply side, the drum gantry device. The kink generated by the accumulation of twist between the drum and the guide sheave is visually inspected to determine the direction and number of kinks, and the drum gantry device is rotationally driven by an amount corresponding to the direction and number of kinks to cancel the wire drawing work. An overhead wire method for carrying out (drawing work) has been proposed.

A wire rope feeding portion 16 having a switchable rotation driving means 15 is provided. A drum holder 18 is provided on the upper surface of the turntable 14 to rotatably hold the drum shafts 17 on both sides of the feeding drum 12, and the feeding drum 12 rotates along with the rotation of the winding drum 13. The wire rope 11 is fed out by rotating around 17. A rotation center shaft 20 is provided at the center of the turntable 14, and the rotation of the drive shaft 21 of the rotation drive unit 15 is transmitted to the rotation center shaft 20 via the power transmission unit 22, whereby the turntable 14. Can be rotated in a horizontal plane around the rotation center axis 20. The rotation driving means 15 can switch the rotation direction of the turntable 14, and can thereby rotate the feeding drum 12 held on the turntable 14 by a predetermined angle around the rotation center axis 20. The rotation drive unit 15 may be any device capable of switching the rotation direction of the turntable 14, that is, any device capable of switching between normal rotation and reverse rotation, but a motor such as a servo motor is preferably used. Moreover, the power transmission part 22 should just be able to transmit motive power from the drive shaft 21 to the rotation center shaft 20, and the combination of a sprocket and a chain, the combination of a pulley and a V belt, etc. are used suitably. The rotation center shaft 20 and the drive shaft 21 may be connected coaxially.

Next, as shown in FIGS. 1A and 1B, a relay unit 24 that relays the wire rope 11 fed out from the wire rope feeding unit 16 is provided on the downstream side of the wire rope feeding unit 16. . The relay unit 24 has a relay roller 26 rotatably held at the upper end of the relay frame 25, and the wire rope 11 is stretched over the relay roller 26 and guided to the twist detection unit 27 provided downstream. The
