0009
前記作業車両本体2の下部走行体21の前側には、履帯の先端よりも前方に突出し、鉄骨等の長尺であって、かつ大型の鋼材(以下、大型鋼材という。)を切断する、上下方向に開閉する切断刃を有する後述する構成になる切断装置3が装着されている。また、前記作業腕24の先端には、作動リンク26によりリンク連結ピン27を介して回動される、後述する構成になる切断・掴持装置5が作業
装置連結ピン25を介して装着されている。
0010
前記切断装置3を、図3乃至図5を参照しながら説明すると、符号31は切断装置本体で、この切断装置本体31は、シリンダ収容部を備え、先端部に下側に凸であって、かつ刃先を上側に向けた「くの字状」に屈曲形成されてなる下部切断刃32aが固着された下部顎体である固定刃保持フレーム32を備えている。

0012
上記のとおり、前記下部切断刃32aおよび上部切断刃34aは「くの字状」に屈曲形成されているが、これらの屈曲の程度は、上部切断刃34aが最も開かれたときには、下部切断刃32aと上部切断刃34aとの中程より先端側の相対する刃先の間隔が中程より先端側が若干大きく開き目になるように、かつ上部切断刃34aが閉じられたときには、先端側になるにつれて下部切断刃32aと上
部切断刃34aとの食違い量が大きくなるように設定されている。これにより掴持状態で大型鋼材を切断することができ、切断中に大型鋼材が下部切断刃32aと上部切断刃34aとの間から外れてしまうようなことがない。
0013
前記切断装置本体31の後部側には、図4、および図5に示すように、側面形状が「この字状」(図4参照)であって、かつ平面形状が矩形状に形成された後述する構成になる接合構造体38が固着されている。この接合構造体38は、前記切断装置本体31の後部側の上下面、および端面の沿う形状に折り曲げ形成され、前記切断装置本体31の後部側を掴持する状態で接合されてなる接合フレーム38aと、この接合フレーム38aの凸側の左右方向の二個所に固着され、側面の上部と下部とにピンが水平に嵌合されるピン嵌合穴が設けられた左右一対ずつのブラケット38b,38bと、一端側が切断装置本体31の両側面に固着され、他端側と上側端面とが前記接合フレーム38aに固着された補強リブ38c、38cとから構成されている。

0015
前記切断・掴持装置5を、図1および図6を参照しながら説明すると、この切断・掴持装置5は、作業装置連結ピン25を介してアーム24bの先端に連結されると共に、リンク連結ピン27を介して作動リンク26が連結される一対のブラケット51(図では、何れも1枚が示されている。)を備えている。これらブラケット51の反連結側には、旋回機構取付板52が固着されており、この旋回

前記旋回機構53には、シリンダ収容部を備え、波状に形成された固定掴持部54bを先端部に備える共に、この固定掴持部54bの奥側に固定切断刃54aを備えた切断・掴持体である固定フレーム54が固着されている。この固定フレーム54の固定切断刃54aの基端部には、前記固定フレーム54の旋回中心と直交する開閉支持ピン56を介して、先端部に前記固定掴持部54bと噛合する
波状に形成された可動掴持部55bを備えると共に、この可動掴持部55bの奥側に前記固定切断刃54aとの間で機材等を切断する可動切断刃55aを備えた切断・掴持体である可動フレーム55が回動可能に枢着されている。
0017
さらに、この可動フレーム55には、前記固定フレーム54の旋回機構53付近に取付けられたボトム連結ピン58を介してボトム側が連結されてなる可動刃作動用シリンダ57のロッドの先端がロッド連結ピン59を介して枢着されており、この可動刃作動用シリンダ57のロッドの伸縮で可動刃保持フレーム55を回動させることにより、固定切断刃54aと可動切断刃55aとで鋼材を切断す
ると共に、固定掴持部54bと可動掴持部55bとで物体を掴持、かつ開放し得るように構成されている。なお、ブラケット51の旋回機構取付板52への固着部付近に明けられた抜き穴から見えるものは、周知の構成になるスイベルジョイント60である。
0018
以下、上記構成になる切断作業車両1の作用態様を説明すると、作業車両本体2の下部走行体21に、固定刃保持フレーム32に固定された下部切断刃32aと、開閉支点ピン33を支点として開閉する可動刃保持フレーム34に固定された上部切断刃34aとを備えた切断装置3を支持させる構成であって、従来例のように、作業腕の先端に装着する構成でないために、この切断装置3を従来より
も小型の作業車両本体に装着しても安定性が損なわれるようなことがない。
これにより、むしろ重心位置が下がって車両の安定性が増し、この切断装置3により安定した状態で長尺で太い大型鋼材を簡単に切断することができるのに加えて、イニシャルコストやランニングコストが安価になり、しかも狭い作業現場にも投入し得るという優れた効果が生じる。さらに、上記のとおり、重心位置が下がって車両の安定性が増すから、大型で能力の高い切断・掴持装置5を装着す
ることが可能になるという効果もある。
0019
また、前記切断装置3の切断装置本体31は、作業車両本体2の下部走行体21に固着した回動支持機構4に回動支点ピン46を介して上下方向に回動可能に支持されていて、下部切断刃32aが取付けられた固定刃保持フレーム32を地盤に預けることにより安定した状態で大型鋼材を切断することがてきるから、大型鋼材の切断作業時における安全性が向上するという効果がある。
0020
さらに、上記のとおり、作業作業本体2の作業腕24の先端には、固定掴持部54bおよび固定切断刃54aを持つ固定フレーム54と、可動掴持部55bおよび可動切断刃55aを持つ開閉自在な可動フレーム55とを備えると共に、この可動フレーム55の開閉支持ピン56と直交する軸心を旋回中心として前記固定フレーム54と可動フレーム55とを旋回させる旋回機構53を備えた切断・

従って、例えば作業現場を移動する場合には取り外した切断装置本体3(接合構造体38を含む)を、搬出すべき切断した大型鋼材を切断・掴持装置5により掴持してトレーラ等に積載したり、切断すべき大型鋼材を切断装置3の位置に移動させると共に、この切断装置3に噛込ませて鋼材等に取付けられている木材等の異材を引きちぎることができ、またプラント構造物の解体に際して生じる種々
の散乱している廃材を選別したり、小型の切断対象物を切断装置3の位置に移動させるまでもなく切断することができるから、大型鋼材の切断作業だけでなく、プラント構造物の解体により生じる種々の廃材を能率良く処理することができ、その汎用性が向上するという効果が生じる。
0022
なお、以上では、旋回機構を備えた切断・掴持装置5の場合を例として説明したが、これに限らず、旋回機構を備えていない構成の切断・掴持装置に対しても、本発明の技術的思想を適用することができるので、上記実施の形態によって本発明の技術的思想の適用範囲が限定されるものではない。
0023
【発明の効果】
以上述べたように、本発明の請求項1に係る切断作業車両によれば、作業車両の下部走行体に、上下方向に相対的に開閉する上部顎体と下部顎体とを有し、前記上部顎体と下部顎体とのそれぞれ相対する側に切断刃を取付け、前記下部顎体に対して前記上部顎体が上下方向に開閉する切断装置を、前記下部走行体に対して上下方向に回動自在に支持されてなるので、この切断装置を装着しても車両の安定性が損なわれることがないから、従来よりも小型の作業車両に大型で大重量の切断装置を装着することができる。これにより、重心位置が下がって車両の安定性が増すので、切断装置により長尺で太い大型鋼材を安定した状態で切断することができ、イニシャルコストやランニングコストが安価になり、しかも狭い作業現場にも投入し得るという優れた効果が生じる。
0024
また、上記の効果に加えて、前記下部顎体に対して前記上部顎体が上下方向に開閉する構成であるから、下部顎体の切断刃で鋼材を支えると共に、下部顎体の切断刃で支えられた鋼材を下部顎体の切断刃と上部顎体の切断刃とにより切断することができる。そして、下部顎体を地盤に預けることにより、より安定した状態で鋼材を切断することができるから、切断作業時における安全性が向上する。
0025
さらに、本発明の請求項に係る切断作業車両によれば、作業腕の先端に装着される作業装置が、少なくとも切断刃および掴持部を有する開閉自在な切断・掴持装置であるから、例えば作業現場を移動する場合には取り外した切断装置を、搬出すべき切断した大型鋼材を切断・掴持装置により掴持してトレーラ等に積載したり、切断すべき大型鋼材を切断装置の位置に移動させると共に、切断装置に
噛ませた鋼材等を引きちぎることができ、またプラント構造物の解体に際して生じる種々の散乱している廃材を選別したり、小型の切断対象物を切断装置の位置に移動させるまでもなく切断することができるから、大型鋼材の切断作業だけでなく、プラント構造物の解体により生じる種々の廃材を能率良く処理することができ、その汎用性が向上するという効果が生じる。
