た。(Technical background of the invention and its problems) Conventionally, when laying ultra-high voltage power cables, a large number of rollers are arranged, and at appropriate intervals,
A caterpillar-type cable feeder is installed, and the cables are fed out one after another by the cable feeder and run on rollers to perform wire extension. At this time,
A rope is connected to the end of the cable, and about three workers use this rope to lift the end of the cable and pull it slightly forward to lead the way. By leading in this way, the tip of the cable is guided along a predetermined route, but if the cable is large, such as an ultra-high voltage power cable, it is heavy and cannot be carried over a long distance (several hundred meters). It takes a lot of effort to hoist it up and lead it. Also, if the cable is an OF cable,
During wire stretching, oil is supplied from the beginning end of the cable using a drum pressure oil tank built into the delivery drum, and after the wire has been stretched, this oil tank is separated and replaced with a working pressure oil tank. However, especially in the case of extending the line into a deep tunnel, the oil supply pipe becomes long after the oil tank is changed, and there is a risk of damage. As a countermeasure to this problem, a long oil supply pipe can be eliminated by attaching an oil supply tank to the end of the cable, but in the case of a large-capacity OF cable, the oil supply tank becomes large, making it difficult to transport within the tunnel.

い。 In FIG. 1, first, a plurality of rollers 1 and a so-called caterpillar type cable delivery device 2 are arranged at appropriate intervals along a wire extension route. The tip end 3a of the cable 3 to be extended is placed on a trolley 4,
It is guided by a guide rope 5 connected to a trolley 4. The trolley 4 passes over the rollers and the cable delivery device 2. At this time, the tip of the cable 3 is connected to a working pressure oil tank 11 placed on a truck 4 via an oil supply pipe 12. Since the cables are sequentially sent out by the cable sending device 2 and run on the rollers 1, when leading the cables with the guide ropes 5, the trolley 4 only needs to face in a predetermined traveling direction.

１はフレーム４ａ上に適宜手段で固定される。 As shown in FIG. 2, the trolley 4 has a gate-shaped frame 4a large enough to pass over the rollers 1 and the cable delivery device 2, and wheels 6 are mounted at four locations at the bottom of both ends of the frame 4a. It is made by arranging it. A cable holding member 8 into which the cable tip 3a can be fitted is provided at the center of the frame 4a. This holding member 8 is divided into two pieces, and one divided piece 8a is attached to the frame 4.
The other split piece 8b holds the cable 3 and is attached to the split piece 8a by a band 9. A handle 10 for tying the guide rope 5 is provided on the frame 4a. A rod 6a that directs the wheels 6 is a threaded rod, and the height of the truck 4 can be adjusted by rotating the threaded rod 6a. The working pressure oil tank 1
1 is fixed on the frame 4a by appropriate means.

させることができる。 When the trolley 4 passes through the caterpillar type cable sending device 2, the cable gripping interval of the device is temporarily widened. However, if the thickness of the holding member 8 holding the cable 3 is reduced to approximate the outer diameter of the cable, the cable can be passed through the cable delivery device 2 as it is without increasing the cable gripping interval.

き、作業効率、安全性の点でも有効である。(Effects of the Invention) As described above, in the method of the present invention, the cable tip is held on a cart that can pass over the roller and the cable delivery device, and a working pressure oil tank connected to the cable tip is placed on the cart. By placing the trolley on the platform and extending the cable while guiding the trolley, the cable can be guided with less effort, which is also effective in terms of work efficiency and safety.
