Description

[Detailed description of the invention] (1) Industrial application field The present invention relates to a cable guide device for a cable feeding vehicle used in overhead distribution line work such as cable extension work.

(2) Conventional technology A cable unwinding vehicle used for work such as cable extension work, for example, as shown in FIG. A cable feeding device 3 equipped with a cable drum 4 is provided, and a bracket 26 is detachably attached to the rear end of the loading platform 2 with bolts or the like.
It is conventionally known that a four-sided roller 27 for guiding the cable is detachably attached to the tip of the bracket 26.

(3) Problems to be solved by the invention The cable guide device of the conventional cable feeder has a four-sided roller removably attached to the tip of a bracket that is removably attached to the rear end of the loading platform with bolts. During work, a bracket must be attached to the rear end of the loading platform, and four-sided rollers must be attached to the bracket. When traveling, etc., the four-sided rollers must be removed from the bracket, and the bracket must be removed from the rear end of the loading platform, making the work difficult. There is a problem in that it is complicated and work efficiency is poor, and since the four-sided rollers are fixed, there is a problem in that the cable is subjected to excessive bending.

(4) Means for Solving the Problems In order to solve the above problems, the present invention provides a cable feeder equipped with a cable drum on which cables, etc. are wound so that they can be fed out, on the platform of a movable vehicle. In the cable guide device of a cable feeding vehicle equipped with a cable guide device, the device is located at the rear end of the loading platform parallel to the left and right direction of the loading platform when stored, and is swingable in a horizontal plane at the rear end of the loading platform so as to protrude to the rear of the loading platform during operation. A guide device is provided with a bracket pivotally connected to the cable drum, and a guide device having a plurality of rollers pivotally connected to the tip of the bracket so as to be able to swing freely in a vertical plane and guide cables etc. that are fed out from the cable drum. be.

(5) Effect With the above configuration, when performing cable overhead line work, the bracket is swung horizontally so that it protrudes to the rear of the loading platform, and the guide device is swung vertically so that the cable The cable fed out from the drum is extended through a guide device. When the cable payout vehicle is run, the guide device is swung back to its original position, and the bracket is swung to store the bracket and the guide device at the rear end of the loading platform parallel to the rear end surface of the loading platform.

(6) Examples Examples of the present invention will be described below with reference to the drawings.

As shown in FIGS. 2 and 3, the cable feeding vehicle is equipped with a cable feeding device 3 on the rear side of a loading platform 2 of a truck 1, which is a travelable vehicle.
This cable feeding device 3 has cables and the like wound around a rotating cable drum 4 so as to be able to be fed out.A equipment shelf 5 is provided on the front side of the loading platform 2 on which equipment necessary for the work is placed. A winch 6 is installed on the loading platform 2 between the equipment 3 and the equipment shelf 5.
A winch 6 extends the cable, etc., wound around the cable drum 4 of the cable feeding device 3. Behind the cable feeding device 3, there is a drive device that drives the cable drum 4 of the cable feeding device 3 and the winch 6. 7 is provided, the drive device 7
selectively drives a sprocket 81 attached to a roller 8 that contacts the outer periphery of the flange of the cable drum 4 and rotationally drives the cable drum 4, and a sprocket 61 attached to the winch 6. A traverser 9 is provided above the winch 6 to wind the rope fed out from the winch 6 in an aligned manner around the winch 6, and at the rear end of the loading platform 2, the rope fed out from the cable drum 4 of the cable feeding device 3 is provided. Cable guide device 10 for guiding cables etc.
However, it is swingably provided so that it protrudes to the rear of the truck 1 during work, and is stored below the rear end of the loading platform 2 during travel. An aluminum body 11 is provided on the loading platform 2 to cover an equipment shelf 5, a winch 6, a traverser 9, a cable feeding device 3, and a drive device 7. On the side of this aluminum body 11, there is a wall for loading equipment onto the equipment shelf 4. A sliding door 12 is provided on the rear surface of the aluminum body 11 to perform the lowering operation, and is opened when performing the work of paying out a cable etc. from the cable drum 4 of the cable payout device 3 and the work of paying out and winding a rope from the winch 5. A shutter 13 is provided on the rear surface of the aluminum body 11, and above the shutter 13 there is a rope guide 18 that guides the rope that is fed out and wound from the winch 6.
is provided.

FIG. 1 shows a cable guide device 10, in which the rear end of a bracket 14 is pivoted below the rear end of a loading platform 2 so as to be swingable and fixed in a horizontal plane.
4 is located below the rear end of the loading platform 2 in parallel with the left-right direction of the loading platform 2 when stored, and is positioned protruding to the rear of the loading platform 2 during operation, and is attached to the tip of the bracket 14 so as to be swingable and fixed in a vertical plane. A guide device 15 is pivotally mounted, and this guide device 15 is positioned on the bracket 14 parallel to the bracket 14 when stored, and is swung upwardly and positioned at an angle with respect to the bracket 14 during operation. The guide device 15 includes a frame 16
and a plurality of rollers 17 which are rotatably mounted vertically and horizontally on this frame 16 and guide cables and the like to be paid out.

With the above configuration, when extending a cable between utility poles, as shown in FIG.
The bracket 14 of the aluminum body 11 is swung horizontally so that it protrudes to the rear of the truck 1, and the guide device 15 is swung vertically to tilt the guide device 15 with respect to the bracket 14. Open the shutter 13 of the drive device 7.
The sprocket 61 is rotated by the winch 6.
is driven to let out the rope 19, and after passing the rope 19 over the metal wheel 21 attached to the utility pole 20 and the metal wheel 23 attached to the utility pole 22 and inverting it, the rope 19 is tied to the metal wheel 24 attached to the utility pole 20, The tip of the rope 19 is connected via the roller 17 of the guide device 15 to the tip of the cable 25 wound around the cable drum 4 of the cable payout device 3. In this state, the sprocket 61 is rotated by the drive device 7, and the winch 6 is rotated. By driving the cable 25 and winding the rope 19, the cable 25 is extended between the utility poles 20 and 22 through the guide device 15 of the cable drum device 10 while maintaining a bending radius of a certain value or more. Also,
When running the cable feeder, the guide device 15 is swung back to its original position so that the guide device 15 is positioned on the bracket 14 in parallel with the bracket 14, and the bracket 14 is swung horizontally so that the bracket 14 and a guide device 15 are positioned below the rear end of the loading platform 2 and parallel to the rear end surface of the loading platform 2.

(7) Effects of the invention As described above, in the present invention, the cable drum device that guides the cables fed out from the cable drum is pivoted in a horizontal plane at the rear end of the loading platform, so that it is easy to operate and store. The present invention provides a cable guide device for a cable feeder that eliminates the need to attach and detach the cable drum at times, and also allows the guide device to swing freely in a vertical plane so that the cable is not forced to bend excessively. This is effective in improving the efficiency of cable extension work.
