[0005] A power supply cable 14 is
Because it is in an ultra-low temperature liquid and maintained in this ultra-low temperature state, when it is lifted on the ground, the moisture in the air freezes on the surface of the cable. If the cable 14 is stored as it is, there is a drawback that the insulation of the cable 14 is reduced. It takes time to dry the cable 14 naturally, and in order to transport the cable 14 wound in an S-shape into the dryer for drying as described later, transport the heavy cable 14 and dry it. Since the operation of storing in the machine is required, drying cannot be performed efficiently.

Since the cleat 30A having or not having the guide rollers 32, 32 'hinders the winding of the cable 14, the cleat 30A is removed from the cable 14 after the cable 14 is lifted on the ground. Removal is preferred. However, when the cleat 30A is removed, the cleat 30A must be reattached to the cable 14 when the cable 14 is hung from the shaft 12, so that the workability of lifting and hanging the cable 14 is reduced. Therefore, cleat 30 is attached to cable 14.
If the cable can be wound without damaging the cable 14 with the A attached, it is preferable because the cleat 30A does not need to be attached or detached.

In the prior art, in order to prevent the cable 14 from being damaged by the cleat 30A when the cable 14 is wound, as shown by reference numeral 14A in FIG. 36, the cable 14 is fixed so that the cleats 30A do not overlap each other. Attempts have been made to wind 14 in the shape of an "8". However, such an operation of winding the cable 14 in the shape of “8” can only be performed manually, and thus has a disadvantage that winding the cable 14 requires a large number of operators.

13 to 15 except that the support is automatically performed and the protective sheet 302 is not used, and thus a detailed description thereof is omitted.

A cable take-up and storage device 10C according to yet another embodiment of the present invention is shown in FIG. 35, in which a take-up section 536 is provided by a moving cart 502, preferably on casters, on which the cable 14 is wound. Consisting of cable 14
Is wound on the movable cart 502 with the casters in the same manner as in the prior art shown in FIG. Further, the storage portion 578 is a protective cover that is detachably fixed to the movable carriage 502 using a latch or the like as shown in FIG. 9 so as to cover the winding body 14A of the cable 14 wound in a figure-eight shape. A drying means 576 in the cover includes a purge port 5 provided in the protective cover 574 for sealing the drying gas.
92 and an exhaust port 594 for discharging the dry gas.

In this embodiment, the cable 14 is wound in an 8-character shape so as to be directly mounted on the movable carriage 502, not on the rotating drum, as shown in FIGS. 3 and 4.
Is substantially the same as the embodiment of FIG. Further, in this embodiment, the cable 14 may be wound in an eight-letter shape on a fixed base instead of the movable carriage 502, but in this case, a lifting ring or the like is attached to the protective cover 574 and a crane or the like is attached. It is preferable to be able to transport to a predetermined storage place. Also,
In this embodiment, a condensed water discharging means as shown in FIGS. 26 and 27 can be provided.

[0090]

According to the present invention, as described above, there is provided a protective cover detachably attached to the base so as to cover the rotating drum, and a drying means in the cover for making the inside of the protective cover a dry atmosphere. Therefore, the cable with the accessory suspended from the shaft can be directly dried at the winding position. Therefore, there is no need to transport the cable to the dryer and take it in and out of the dryer, and since the protective cover functions as a rain cover, the cable can be stored as it is without transporting it to a storage location.

Also, since the floor surface of the base to which the protective cover is attached is inclined and the condensed water discharging means is provided with a discharge port provided at the lowest position, a cable which can be lifted in a vertical shaft in an extremely low temperature state is provided. Even if moisture condenses and this condensation dissolves in the protective cover and water is generated, the water can be reliably discharged, and thus a decrease in insulation of the cable can be prevented.

Further, when winding the cable with the accessory on the rotating drum, the protective sheet is wound together with the winding of the cable or wound out of the cable so as to be continuously interposed between the adjacent cable turns. Since the protective sheet intervening means is provided, the cable can be wound up and stored without removing the accessory from the cable with the accessory and without damaging the cable.

When the rotating drum is arranged vertically,
Since the cable suspended above the ground is supported by the support means before the rotating drum, there is no need for the operator to support the cable between the shaft and the rotating drum even if there is a gap between the shaft and the rotating drum. The picking operation can be performed efficiently.

Furthermore, since the direction of the rotating drum can be freely changed by the drum swing mechanism or the moving carriage, it is possible to wind a cable in an arbitrary shaft in a plurality of shafts, and the moving carriage can rotate. The drum can be easily transported, and its storage and management can be facilitated.

As described above, since the winding, drying and storage of the cable can be performed in a place close to the shaft, the number of workers required for these operations can be significantly reduced.
Therefore, winding and storing of the cable can be performed with high workability.
