At this time, the bundled wire T is held in a standing state by the fences 78, 78 and the stop jigs 80, 80. Then, the operator transports the carriage 75 carrying the bundled wire T from the unloading place to the actual laying site by pushing or towing the carrier.

When the bundle T is transported to the laying site, as shown in FIG. 17, the transport vehicle is positioned so that the bundle T is positioned on the opposite side of the turntable 59 of the take-up / delivery device F that has been arranged in advance. Adjust the position of 75 and further approach the take-up / delivery device F. Then, the take-up / delivery device F and the carriage 75 are connected and fixed by the connecting jig 85. Note that the fence 78 on the turntable 59 side is removed before reprinting.

On the other hand, in preparation for the take-up / delivery device F side, the leading end 69 of each of the inclined members 60 is removed, and the rotating mechanism 74 is operated to reduce the interval between the inclined members 60 to reduce. Keep the diameter. Further, in order to facilitate the transfer of the bundled wire T to the guide section 5, the screw jack 63 is adjusted to expand and contract to make the inclination angle of the turntable 59 close to a right angle (the turntable 59 stands upright).

When the preparation is completed in this way, the transport trolley
By operating the forward / backward movement mechanism 82 of 75 and sliding the bundled wire T toward the turntable 59 while standing, the bundled wire T is transferred to the take-up / delivery device F. Thereafter, the tip portions 69 are attached to the respective inclined members 60, and the diameters of the respective inclined members 60 are increased substantially in accordance with the inner diameter of the bundled wire T.

After installing the bundled wire T on the turntable 59, the screw jack 63 is operated to turn the turntable 59.
At a predetermined inclination angle. In this case, it is desirable that the center of rotation of the turntable 59 substantially coincides with the center of gravity of the winding / sending device F. In this way, when the attachment of the bundled wire T to the take-up / delivery device F is completed, the take-up / delivery device F is transported to a predetermined laying site if necessary, and then the linear body is removed from the bundled wire T. If the motor 68 is operated after the tapping, the wire drawing operation can be performed. In this case, the transport cart 75 connected by the connecting jig 85 plays the role of an outrigger, so that stable delivery can be performed.

FIG. 18 shows a case where the above-mentioned carriage 75 for transferring the bundled wire T to the winding / sending device F is omitted. The outrigger 86 is attached to the base frame 1 and the outrigger 86 is extended. An iron plate 87 is disposed on the front side of the turntable 59 using a bar. A slope 88 is continuously provided at an end of the iron plate 87. FIG. 18 illustrates a slope that is inclined toward the front of the drawing.

In this way, after transporting the bundled wire T to the vicinity of the winding / sending device F, the slope 88 is raised while rotating the bundled wire T in a standing state and rotated to the front of the center of the turntable 59. It can be conveyed, and thereafter, the bundled wire T can be transferred to the turntable 59 side. Also at this time, the distal end portions 69 are removed from the inclined members 60 and the guide portion 5 is kept in a reduced diameter state.

The case where the winding / sending device F is used for both winding and feeding of the bundled wire T has been described above. However, the linear body S is wound up at the factory to form the annular bundled wire T. If formed, figure
A winding device 89 as shown in FIG. 19 may be used. The take-up device 89 drives the base frame 1 provided with casters 90 and the outriggers 91, a vertical rotation shaft 92 rotatably provided on the base frame 1, and a rotation shaft 92 via gears. Motor 93, and a guide frame 94 provided at the upper end of the rotating shaft 92, the guide frame 94 is a large-diameter lower frame 95
And a small diameter upper frame 96, and a connecting portion for connecting the upper frame 96 and the lower frame 95.
97.

When winding a linear body using this winding device 89, the end of the linear body is fixed to the connecting portion 97, and the motor 93 is driven to rotate the guide frame 94 in the winding direction. Good. At this time, an operator changes the winding position by moving the linear body up and down so that the linear body is uniformly wound. After the winding, a plurality of portions of the bundled wire formed in an annular shape are fastened by a fastening member, and the bundled wire is taken out from the guide frame 94 using, for example, a hoist.

The winding / sending device F (second embodiment) is not limited to the above description, but can be variously modified. For example, a rotation mechanism 74 for expanding and contracting the interval between the inclined members 60 of the guide section 5 may be arranged on the back side of the turntable 59 so as to further reduce the size of the apparatus. In FIG. 18, instead of rolling and transporting the bundled wire T using the iron plate 87 and the slope 88, a chain-type lifting hook or the like is provided from the base frame 1 to the front of the turntable 59, and the bundled wire T is moved forward. , The bundled wire T may be lifted by the hook and attached to the turntable 59.

Further, in order to enhance the mobility at the time of extending the wire, a turning plate is provided on the base frame 1 and a turntable 59 is provided thereon so that the turntable 59 can be swung. Is also preferred. Further, a generator serving as a power supply for the motor 68 may be separately mounted, or an engine may be mounted instead of the motor.

Even if it is S, it can be easily achieved.

Further, in this drumless method, since the drum and the packing material for holding the bundled wires T which have been commercialized can be omitted, the waste material generated by disassembling the packing material at the site can be eliminated, and the drum can be collected. Work becomes unnecessary. In other words, waste drums are not generated, which contributes to resource saving and
There is no need to transport and dispose of waste drums (cost is reduced). In addition, since the bundled wire T can be directly loaded on the transport vehicle K, the loading efficiency is improved, and the transport amount per operation can be increased (transportation cost is reduced). Further, the wire drawing operation of the linear body S can be easily and efficiently performed without using the drum.

When attaching the bundled wire T to the delivery device (for example), the bundled wire T is vertically lifted by, for example, a lifting hook of a hoisting machine, and the bundled wire T is kept in the vertical state. Can be fitted into the guide portion 5, and the mounting operation can be easily performed. After the mounting, the switching arms 9 are switched to the upright state to form the front flange 8, so that the bundled wire T can be securely held even in the vertical state, and can be stably held. Then, the bundle T can be sent out.

Further, in the factory, the omission of the drum saves space in the stocking location of the bundled wires T. Also, when the base frame 1 is provided with wheels to be portable, compared to the case where the bundled wire T is transported in a state of being laid in the lateral direction, a large space in the width direction is not required and transport to a narrow place is easy. It becomes possible.

According to the fifth aspect, the bundled wire T can be smoothly mounted from the guide portion 5 when the front flange portion 8 is parallel. According to the sixth aspect, the parallel / vertical switching structure of the switching arm body 9 is simple.

At this time, since the turntable 59 has an inclined standing shape, it can be wound up and sent out more stably as compared with the case where the turning table 59 is vertically standing. Further, in the factory, the omission of the drum saves space in the stocking location of the bundled wires T. Also, when the base frame 1 is provided with wheels to be portable, compared to the case where the bundled wire T is transported in a state of being laid in the lateral direction, a large space in the width direction is not required and transport to a narrow place is easy. It becomes possible.

In the case where the annular bundle T is attached to the rotary frame 3, the turntable 59 is made to stand almost vertically, so that the bundle T is attached to the inclined members 60. Can be easily and quickly fitted and mounted, thereby improving workability.

According to the ninth aspect, the winding diameter of the linear body S can be adjusted according to the winding amount and the minimum allowable bending radius.
