本発明は、穴掘装置を有するクレーン車の掘削力増加装
置に関するものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a digging force increasing device for a crane vehicle having a hole digging device.
一般に、穴掘時ドリル部に押込力を与えるのは主として
ドリル部及びクレーンブームの自重であるが、従来車両
の軽量化に注目し過ぎたため、ドリル部の自重が不足し
、増加傾向にある掘削トルクに比べて、押込力が不足す
る欠点があった。In general, it is the dead weight of the drill part and crane boom that provides the pushing force to the drill part when digging a hole, but as conventional vehicles have focused too much on reducing the weight of vehicles, the weight of the drill part is insufficient, and this is increasing. There was a drawback that the pushing force was insufficient compared to the torque.
本発明は上記の欠点に鑑みてなされたもので穴掘時に重
錘を付加することにより、向上したトルク性能に見合う
だけの押込力をドリル部に与えその掘削性能を更に向上
させることを目的とするものである。The present invention has been made in view of the above-mentioned drawbacks, and an object of the present invention is to further improve the drilling performance by adding a weight to the drill part to provide a pushing force commensurate with the improved torque performance. It is something to do.
以下、本発明の一実施例を第１図により説明すると、１

てのサブジブ６が嵌挿され、各々のブーム３，５．６は
図示しない伸縮機構により自在に伸縮可能である。Hereinafter, one embodiment of the present invention will be explained with reference to FIG. 1.
is the frame of a crane truck that has been stably installed with jacks.
A base boom 3 of a crane boom is pivotally supported 4 on a swivel base 2 mounted on a vehicle frame 1, and a telescopic boom 5 is mounted within the base boom 3.
Furthermore, a sub-jib 6 as a tip boom is fitted into the telescopic boom 5, and each boom 3, 5.6 can be freely extended and contracted by an unillustrated telescopic mechanism.
穴掘時においてドリル部７は前記伸縮ブーム５の先端部
より揺動自在に吊下されており、前記サブジブ６の先端
より適宜、重錘９がフック８により吊下される。When digging a hole, the drill part 7 is swingably suspended from the tip of the telescopic boom 5, and a weight 9 is appropriately suspended from the tip of the sub-jib 6 by a hook 8.
次に本発明の作用について説明すると、穴掘作業を行う
場合、ドリル部７を格納位置より張出し適当量伸長した
ブーム５の先端より懸吊吊下し、穴掘作業を可能にする
と共にサブジブ６のフック８を図示しないウィンチ機構
により巻下げ、前記の重錘９を吊下する。Next, to explain the operation of the present invention, when performing hole-digging work, the drill part 7 is extended from the storage position and suspended from the tip of the boom 5 that has been extended by an appropriate amount, thereby making it possible to perform the hole-drilling work and making the sub-jib 6 The hook 8 is lowered by a winch mechanism (not shown), and the weight 9 is suspended.
次にドリル部７を回転機構により回転させ掘削を始める
と、ドリル７に重錘１０の自重の分だけ押込力が付加さ
れて掘削性能が向上し、穴掘を行う。Next, when the drill part 7 is rotated by the rotation mechanism and drilling is started, a pushing force corresponding to the weight of the weight 10 is applied to the drill 7, improving the drilling performance and digging a hole.
また、掘削作業終了後はフック８を再び巻下げることに
より重錘９は容易に取りはずすことが出来、以後の作業
に何ら支障をきたすことなく、クレーン車の自重が増加
することもないというものである。In addition, after the excavation work is completed, the weight 9 can be easily removed by lowering the hook 8 again, which does not interfere with subsequent work and does not increase the weight of the crane vehicle. be.
また、他の車種における実施方法例としては第２図、第

在に枢着１１され、第２図すはその伸長状態でありこれ
より枢着部１１を中心に１８０度回転すると格納状態と
なる。Examples of the implementation method for other vehicle types are shown in FIGS. 2 and 3. In FIG. 2, the drill part 7 is suspended in the same way as in FIG. A side-folding type sub-jib 10 serving as a tip boom is rotatably attached to the tip 11, and Fig. 2 shows its extended state, and when it rotates 180 degrees around the pivot 11, it becomes retracted. .
そして伸長した横折れ式サブジブ１０の先端に図示しな
い別設置のウィンチ機構により、重錘を吊下して第１図
と同様の作用をすることになる。Then, a weight is suspended from the tip of the extended side-folding type sub-jib 10 by a separately installed winch mechanism (not shown), and the same effect as shown in FIG. 1 is performed.
（第２図ａ）。(Figure 2a).
また、第３図には、３段以上の多段ブーム車が記載され
ており、ドリル部１は通常、先端ブーム１３の先端部（
点線Ｔの位置）に懸吊されるが、本発明の場合は吊下し
た重錘９とドリル部γが干渉しないように、ドリル部７
はある距離りだけ移動して懸吊される。Further, FIG. 3 shows a multi-stage boom vehicle with three or more stages, and the drill part 1 is usually located at the tip of the tip boom 13 (
However, in the case of the present invention, the drill part 7 is suspended so that the suspended weight 9 and the drill part γ do not interfere with each other.
moves a certain distance and is suspended.
以上のことより本発明は押込力の増加を特別な機構や装
置を用いることなく先端ブームより懸吊されるフックを
利用して達成し、簡単である上に効果的な結果が得られ
非常に有用なものである。From the above, the present invention achieves an increase in pushing force by using a hook suspended from the tip boom without using any special mechanism or device, and it is simple and provides very effective results. It is useful.
