本考案はクレーンブームに穴堀装置を備えた穴
堀建柱車のブームに関するものである。[Detailed Description of the Invention] The present invention relates to a boom for a digging pole erecting vehicle, which has a crane boom equipped with a drilling device.

いう欠点を有していた。 As shown in Fig. 1, the drilling pole erecting vehicle is constructed by fitting a support 7 with a drilling device 8 attached to the outer periphery of the inner boom 2 of the crane booms 1 and 2, which extend and retract. However, since the boom head 3 protrudes ahead of the drilling device 8, it can be used for drilling near old utility poles or near walls when rebuilding utility poles. The boom head 3 sometimes becomes an obstacle.

るものである。 The present invention was developed in view of the above-mentioned circumstances.The boom head is pivotally attached to the tip of the inner boom by a horizontal pin, and this boom head can be swung toward the upper surface of the tip of the inner boom, thereby making it possible to perform drilling work. Sometimes, the purpose is to swing the boom head to the top side of the boom tip so that the boom head does not become an obstacle to drilling work.

いる。 Embodiments of the present invention will be described below with reference to the drawings. As shown in FIG. 2, a boom head 3 is pivotally attached to the upper part of the tip of the inner boom 2 by a horizontal pin 4, and a guide sheave 9 is coaxial with the boom head 3.
is pivotally supported, and the guide sheave 1 is attached to the boom head 3.
1 is pivotally mounted 10, and a winch (not shown)
The wire rope 6 let out is stretched over the guide sheave 9 and the guide sheave 11, and then over the sheave 12 of the hanging hook 5, and the tip of the wire rope 6 is fastened 14 to the boom head 3. FIG. 2 shows the crane working state, in which the support 7 is locked to the tip of the outer boom 1, and the drilling device 8 is stored on the side of the outer boom 1.

い。 With the above configuration, when performing drilling work,
After locking the support 7 to the tip of the inner boom 2 and suspending the drilling device 8, the boom head 3 is swung around the horizontal pin 4 by winding the winch and making the wire rope 6 into a spiral state. , as shown in FIG. 3, the boom head 3 is positioned on the upper surface of the tip of the inner boom 2. In this state, the boom head 3 is retracted and does not protrude ahead of the drilling device 8.

に有効である。 As described above, according to the present invention, with a simple configuration, it has the same function as a conventional boom during crane work, and the boom head does not protrude ahead of the drilling device during drilling work. Since the boom of the present invention is provided, it is possible to perform digging work on utility poles, walls, etc., and is effective in improving the functionality of the digging and pole-erecting vehicle.
