る。[Prior art] Conventionally, to supply power to a shield machine during tunnel excavation, a cable wound in a figure eight is placed on a flat truck that moves with the shield machine, and the cable is manually moved as the shield machine moves. I was trying to send it off. This is a labor-intensive and dangerous task. To address this issue, devices have been provided for delivering cables wrapped around drums. Among these devices, the one in which the cable is wound around the drum in several layers has a large iron loss, and as the number of turns increases, the iron loss increases and the voltage drops. To deal with this voltage drop, thicker cables increase the outside diameter of the drum and prevent it from entering the mine shaft. On the other hand, if a single winding is applied to a bobbin-type drum, the iron loss will be reduced, but there is a problem that the length of the drum will become longer.

が、前記の公知例と同様な欠点を有している。 For example, Japanese Utility Model Publication No. 56-52742 discloses a technique in which a cable is wound using a take-up reel provided on a truck, and the running speed of the truck is controlled in accordance with the rotational speed of the reel. However, as mentioned above, voltage drops are likely to occur due to magnetic field generation. Japanese Patent Publication No. 59-42530 also discloses a technique for winding a cable onto a take-up reel, but it has the same drawbacks as the above-mentioned known example.

Hard to occur. During work, the screw provided on the upper arm is rotated by a control motor, and the roller of the automatic insertion/extraction device can be used together with the screw to automatically send in and out the control cable according to the amount of movement of the cart. It is also relatively easy to wind and unwind in a figure 8 shape. The pair of upper and lower arms can be tilted by the arm posture control device, so when winding up the cable, the arms are tilted upward to make it easier for the screw to move the cable to the back of the arm. When feeding out the cable, it can be tilted downward to make it easier to feed out the cable.

力を供給する場合に極めて好適である。 Therefore, despite the work of winding in a figure-eight pattern with right-handed and left-handed winding, handling is easy and work efficiency is improved, and it is especially suitable for shielding machines used in civil engineering work.
It is extremely suitable for supplying power to something that travels relatively long distances, such as a trolley.

The arm portion 30 of the cable winding machine 1
As will be described later, the front side of the wound cable 2 is connected to the cubicle 6 of the power unit 5, and the rear side is guided by the screw 34 and comes into contact with the lower surface of the tension detection roller 26, and is connected to the guide rollers 24, 24 and the cable feed. It is held between output rollers 22, 22, and its rear end is connected to an intermediate box 8 connected to a relay cable 7. Electric power is then sent to the power unit 5 via the intermediate box 8, the cable 2 and the cubicle 6, and the shield machine 3 excavates. When the cable winding machine 1 moves together with the driving cart 4 following the digging of the shield machine 3, the control device 50 controls the feed control motor 33 and the cable control motor 2 based on the detection signal of the movement amount sensor 13.
Controls the rotation speed of 1. Under this control, the screw 34 rotates and feeds out the cable 2 according to the amount of movement of the trolley 10, and the cable feed-in/out roller 22,
22 rotates and sends out the cable 2 sent out by the screw 34 in accordance with the amount of movement of the truck 10. At this time, since the rear end of the arm 30 is lowered by turning the arm posture control handle 44, the cable 2 is smoothly fed out by the rearward tilt of the upper arm 31 and the roller 32. In addition, if abnormal tension occurs in the cable 2 due to a malfunction in feeding, the cable 2 causes the tension abnormality detection roller 26 to be activated by the springs 25 and 2.
An alarm device is lifted up against the driver's cart 4 and the operator can correct the malfunction by manual operation.

ることができる。 Next, the cable 2 wound on the flat truck 9
is wound around the arm portion 30. For winding, the cable control motor 21 rotates the cable feed-in/out rollers 22, 22 in the opposite direction to the direction in which the cable 2 is fed into the arm portion 30. The rear end of the arm 30 is raised by turning the arm posture control handle 44 in the opposite direction to the direction when sending out. Therefore, the cable 2 is wound around the upper arm 31 in a right-handed manner and around the upper arm 35 in a left-handed manner, for example, in a figure-eight pattern. At this time, the cable 2 can be easily wrapped by the forward tilt of the upper arm 31 and the roller 32. In this way, cable 2
Since the wire is wound around the arm portion 30 in a figure-eight pattern alternately with right-hand winding and left-hand winding, voltage drop due to iron loss can be eliminated.
