Description

[Detailed description of the invention] (1) Industrial application field The present invention relates to a cable feeding and winding work vehicle used in distribution line construction such as bypass construction.

(2) Conventional technology In work such as bypass construction, cables of different diameters or lengths are used. A work vehicle is used which includes a revolving body which is fixedly pivoted and has a plurality of cable drum attachment parts.

(3) Problems to be solved by the invention However, the conventional cable feeding and winding work vehicle is limited by the size of the cable drum.
In order to use a larger diameter cable drum, the number of cable drums must be reduced, and
Since the arm had to be reinforced to cope with the increased weight, there was a problem in that the device became larger.

(4) Means for Solving the Problems In order to solve the above problems, the present invention provides a plurality of cable drums each attached to a different position of a circulating annular chain, and a method for connecting these cable drums to a predetermined position. The cable drum fixing device selectively fixes the cable drum at the predetermined position, and the cable drum drive device connects with the cable drum and rotationally drives the cable drum when the cable drum is located at the predetermined position.

(5) Effect With the above configuration, the annular chain is circulated to select a cable drum, the cable drum fixing device fixes the selected cable drum in a predetermined position, and the fixed cable drum is rotated by the cable drum drive device. It is driven to perform cable feeding or winding work.

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

As shown in FIG. 1, an annular chain 5 is looped between a pair of sprockets 3 and 4 which are respectively pivotally supported on both sides of a frame 2 provided on a loading platform 1. Cable drums 6, 7, 8, 9, 10 are installed at different positions, and a cable drum fixing device 11 is provided at the rear of the frame 2 to fix the cable drums 6 in a predetermined position. The cable drum 6 fixed by a cable drum 11 is connected to a cable drum drive device 12 and driven to rotate. 13 is the traverser arm, 14 is the cable 1
This is a four-sided roller that guides the roller.

As shown in FIG. 2, the sprocket 4 rotates as the rotation of the motor 35 is transmitted by the sprocket 32, chain 33, and sprocket 31, circulates the annular chain 5, and connects the cable drum 6,
7, 8, 9, 10 are brackets 36, 37, 3
8, 39, 40 respectively attached to the annular chain 5, each cable drum 6, 7, 8, 9,
Gears 16, 17, 18, 19, 2 are on the side of 10.
0 is fixed to the shaft of the cable drum, and rollers 26, 27,
28, 29, and 30 are rotatably attached. The cable drum fixing device 11 includes rollers 26, 27 of each cable drum 6, 7, 8, 9, 10,
The cable drum driving device 12 consists of a pair of cams 21 that position each cable drum by contacting cams 28, 29, and 30, and a pair of clamp cylinders 22 that clamps a roller between the cams 21 and fixes the cable drum. The rotation of the motor 34 is transmitted to the gear 23 via the sprocket 24 and the chain 25, and the gear 23 has each of the cable drums 6, 7, 8, 9, and 10 fixed by the cable drum fixing device 11. It meshes with gears 16, 17, 18, 19, and 20 of each cable drum at the position shown in FIG.

With the above configuration, when performing work such as bypass construction, the motor 35 is driven and the annular chain 5
The roller of the cable drum to be used contacts the cam 21 of the cable drum fixing device 11 to stop the circulation of the annular chain 5, and the clamp cylinder 22 is extended to fix the cable drum. The gear meshes with the gear 23 of the cable drum drive 12. next,
The cable is paid out or wound up by driving the motor 34 of the cable drum drive device 12 to rotate the cable drum forward or reverse.

(7) Effects of the invention As described above, according to the invention, the cable drum to be used can be selected from a plurality of cable drums simply by circulating the annular chain, and the unused cable drums are stored in two tiers. It is possible to use a large diameter cable drum, and
Since the entire device is compact, it has the advantage that it can be mounted on a small vehicle.
