Description

[Detailed Description of the Invention] The present invention relates to a device for feeding electric wires such as cables and wires used for power transmission and distribution to predetermined locations.

As this type of feeding device, a plug-in drum winch type is conventionally known, but it has the disadvantage that its main body is large and requires a large installation space. Recently, smaller and improved devices have appeared, but in order to resist the tensile force of the cable that appears as a reaction when the cable is fed, the device must be fixedly installed, and it is necessary to use hand holes as relay boxes or sandy areas. The drawback was that it could not be used in places where it was difficult to install it permanently.

The present invention was devised to eliminate the above-mentioned drawbacks, and is achieved by connecting a socket to the inlet of the feeding device and engaging one end of the socket with the open end of a fixed pipe used for piping, etc. , the tensile force caused by the wires during feeding is absorbed by a fixed pipe. Additionally, this allows the device to be used without being fixed.

Reference numeral 87 denotes a sprocket that is interlocked with the reversing sprocket 63 of the thick wire feeding section 15 via a chain 64, and the shaft 88 of this sprocket 87 is connected to the side plate 26 on one side of the main body case 5 and the inner and outer sides of one side of the chassis 73. It is pivotally supported by side plates 76 and 74 of. A gear 89 is attached to the shaft 88 of the sprocket 87, and this gear 89 meshes with a gear 90 coaxially with the lower middle gear 81. In this way, when the sprocket 87 is rotated in the direction of the arrow by the chain 64, the upper groove rollers 95, 9

Adjust the adjustment springs 91, 92 and the adjustment gear 93 to adjust the upper grooving roller 9.
By moving the shafts of 5, 96, and 97 up and down while maintaining the meshing state between the gears, the distance between the grooving rollers 95 and 98, 96 and 99, and 97 and 100 can be varied at the same time, for example, in the range from 1 mm to 5 mm. It is configured so that it can be done. A limiter 94 is provided at the entrance of the thin wire feeding section 16 to prevent the insertion of the thick wire cable 17. When the tip of the cable 17 hits this limiter 94, a micro switch or the like is activated. It is formed to stop the power supply and prevent thick wire cables from entering the thin wire feeding section 16.

Next, the operation of the present invention will be explained based on the drawings.

First, the lead-in wire 71 is coupled to the core wire exposed by peeling off the coating at the tip of the cable 17, and the lead-in wire 71 is used as a guide wire for the cable 17. Next, insert the tip of this cable 17 into the fixed pipe 3, and insert the lead-in wire 7.
1 is passed between the socket 4 of the inlet section 6 of the device and the belts 18 and 19 of the thick wire feed section 15, and then passed through the upper and lower rollers 9 on the entrance side of the thin wire feed section 16.
Insert between 5 and 98. Next, the inlet section 6 of the device
Fix one end of the socket 4 connected to the pipe 3
engages the open end of the When the hydraulic pump 50 is driven here, the hydraulic motor 45 rotates, and the rollers 20, 21, 22, 2 of the thick line feeding section 15 are driven through transmission means such as sprockets, chains, gears, etc.
3, 24, and 25 rotate in the direction of the arrow as shown in FIG. 1, and the upper and lower endless belts 18, 19 also rotate in the direction of the arrow. At the same time, the upper and lower grooving rollers 95, 96, 97, 98, 99,
100 also rotates in the direction of the arrow, so the retracting wire 71 held between the groove rollers 95 and 98 on the entrance side is fed rightward. As this feeding progresses and the covered portion of the cable 17 passes over the sliding roller 66 at the entrance of the thick wire feeding section 15 and is drawn between the upper and lower endless belts 18, 19, the endless belt 18, 19 holds the cable 17 and feeds it to the right in the figure. When this feeding progresses further and the tip of the coated portion of the cable 17 hits the limiter 94 of the thin wire feeding section 16, the micro switch is activated to turn off the power switch and the operation of the hydraulic pump 50 is stopped. This causes the sending to be interrupted. At this point, the fine wire feeding section 16 is removed from the main body case 5 by removing the mounting bolt 75. Then, when the power switch is turned on, the feeding action of the cable 17 by the thick wire feeding section 15 is resumed, and the cable 17 is fed into a predetermined location from the outlet section 72 of the main body case 5. In addition, in the case of feeding the wire, the wire can be fed to a predetermined location by the action of only the thin wire feeding section 16.

In the present invention, as described above, a socket is provided at the inlet of the device main body, and this socket is configured to be removably engaged with the open end of the fixed pipe, so that the tensile force acting on the device when feeding the electric wire is reduced. can be absorbed by a fixed pipe. Therefore, there is no need to fix the main body of the device, so as long as there is a fixed pipe, it can be used as a relay box in a hand hole or in a place that is not suitable for a fixed device, such as a sandy place. Furthermore, since the device can be freely attached to and removed from the fixed pipe, handling of the device is extremely convenient. Moreover, it is equipped with a feeding section for thick wires, which feeds the electric wire while sandwiching it with an endless belt that rotates on both sides, and a feeding section for thin wires, which feeds the core wire and lead-in wire. Regarding electric wires, the wire can be easily guided to the thick wire feed section using the thin wire feed section, and the wire itself can be directly fed into a predetermined location using the thick wire feed section. can. Furthermore, since the fine wire feeding section is provided with a limiter on the inlet side, it is possible to prevent the electric wire from being accidentally inserted into the thin wire feeding section.
