Description

[Detailed Description of the Invention] [Industrial Application Field] This invention relates to a device that lowers and automatically winds up a wire extending in the vertical direction.

[Prior art]

Conventionally, as a device for automatically lowering and automatically winding up a wire (wire rope) extending in the vertical direction, an automatic winding device disclosed in Japanese Utility Model Application Publication No. 56-88786 has been known. In the case of this automatic winding device, as shown in FIG. An annular wire accommodating portion 12 is disposed within the outer enclosing frame 4 and fixed to the circular plate 5, and is provided between the outer enclosing frame 4 and the inner enclosing frame 3. Ring frame 4a
A wire insertion notch is provided in the central part of the guide arm mounting base 2, and a cylindrical body 6a for opening and closing the notch is slidably fitted therein, and is fixed to the upper end of the inner enclosure frame 3. A guide arm 1 is installed to be able to rotate horizontally, and the guide arm 1
A wire guide portion 1a located above the wire accommodating portion 12 is provided at the distal end portion of the wire guide portion 1a.

For example, when the grab bucket 11 and the grab bucket opening/closing wire 7 are replaced simultaneously as a pair during cargo handling on a specialized ore ship, etc., the wire 7 is automatically wound using the conventional automatic wire winding device. First, the cylindrical body 6a is moved in the longitudinal direction of the ring frame 4a from the position shown in FIG. 1 to open the wire insertion notch in the ring frame 4a, and then the wire winding drum 1
Any part of the wire 7 hanging from 0,
The wire is inserted into the wire accommodating portion 12 through the wire insertion notch and is also inserted into the wire guide portion 1a of the guide arm 1. In this state, the portion of the wire 7 on the grab bucket 11 side hangs down from the upper part of the grab bucket 11 to the ground, and reaches the wire accommodating portion 12 through the ground.

Next, when the wire 7 is unwound from the drum 10, the guide arm 1 naturally rotates in the same direction as the twisting direction of the wire 7 due to the weight and deflection of the wire 7.
The wire 7 is guided spirally onto the circular plate 5 in the wire storage section 12. After the wire 7 has been wound up by a predetermined amount between the inner enclosure frame 3 and the outer enclosure frame 4 in this way, The wire connecting fitting 20 connecting the wire 7 and the messenger wire 21 fed out from the wire is separated, and the work of removing the wire 7 and the grab bucket 11 is completed.

[Problem that the invention attempts to solve]

When the wire 7 unwound from the drum 10 as described above begins to be stored in the wire storage part 12 in a spiral manner, the wire 7 is twisted in the same direction as the wire twisting direction due to the swirling of the wire 7. Occur.

On the other hand, the grab bucket 11 and the wire storage section 1
2, the length of the wire that hangs down from the top of the grab bucket 11 to the ground is relatively short, for example, about 7 to 8 m, and the other part extends beyond the ground. Because it is on,
Almost no tension is generated in the wire 7 between the grab bucket 11 and the wire accommodating part 12.

For this reason, the twisting that occurs when the wire 7 unwound from the drum 10 begins to be stored in the wire storage part 12 in a spiral manner is caused by an open position on the side of the wire 7 hanging down from the upper part of the grab bucket 11 to the ground. The wire 7 is twisted as shown in the dotted line A.

Next, when winding the twisted wire 7 onto the drum 10, if the twisted wire 7 is wound up and stretched by the drum 10, a kink will occur in the twisted part, which will shorten the life of the wire 7. It has the disadvantage of being short.
