A telescopic boom 5 is a telescopic boom formed by telescopically inserting a telescopic boom into which the base end is mounted on a swivel base 4 mounted on a vehicle 3 so as to be movable up and down.
A drill drive motor 7 is swingably attached to a support fitting 6 that is alternately attached to the tip 1a of the outermost boom 1 of the telescoping boom 5 and the appropriate position 2a of the inner boom 2, and the output shaft of the motor 7. A connecting rod 9 whose proximal end is connected to the connecting rod 8 and rotationally driven by the motor 7, and a connecting rod 9 which is telescopically fitted on the connecting rod 9 but not relatively rotatable, and whose extension/contraction position with respect to the connecting rod 9 can be arbitrarily fixed. The drill device 12 includes a drill shaft 11 having a spiral blade 10 on the outer periphery except at least the base end thereof. In order to excavate a hole in a utility pole with the hole-drilling pole-erecting vehicle constructed in this manner, first attach the support fitting 6 to the appropriate position on the inner boom 2 of the telescopic boom 5, and then move the drill device 12 approximately perpendicularly from the appropriate position on the inner boom 2. Then, the drill shaft 11 is extended from the connecting rod 9 to a length corresponding to the depth of the hole to be drilled and fixed. Then, the drill drive motor 7 is driven to drive the drill device 12.
By extending and contracting or raising and lowering the telescopic boom 5 while rotating the drill device 12, the position of the drill device 12 is adjusted to drill a hole in the utility pole. After the excavation is completed, the drilling device 12 is stored along the telescopic boom 5 using the following storage device so that the drilling device 12 does not interfere with the traveling movement of the drilling device 12. That is, the flange 13 is fixed to the outer periphery of the base end of the drill shaft 11 of the drill device 12, and the flange 1
A wire rope end fastening device 14 is provided on the outer periphery of the drill shaft on the distal side of the drill shaft 3, and the wire end of the wire rope 15 suspended from a proper position on the outermost boom 1 of the telescopic boom 5 is attached to the wire rope end fastening device 14. After connecting, the drill shaft 11 is rotated by the drill drive motor 7, so that the wire rope 15 is wound around the drill shaft 11 while being guided by the flange 13, and the drill device 12
was designed to be stored along the outer boom 1.

あつた。(Problems to be Solved by the Invention) However, in the conventional drill device storage device for the hole-drilling and pole-erecting vehicle constructed as described above, the drill shaft 11 is extended from the connecting rod 9 in order to excavate a deep hole. If you try to store it as it is, the flange 1 provided on the outer periphery of the base end of the drill shaft 11
3 is of a fixed type, the flange 13 moves to the position shown in FIG. 4 as the drill shaft 11 extends. In this state, the cable end of the wire rope 15 suspended from the telescopic boom 5 is attached to the wire cable end fixing device 1.
4 and try to wind up and store the wire rope 15, the wire rope 15
is wound up over the flange 13,
There were problems such as damage to the wire rope 15 and the inability to carry out a smooth storage operation. For this reason, the drill shaft 11 has been reduced each time the drill device 12 is stored, but this work is very complicated.
