Abstract
Description
本発明の一実施形態による油圧ショベル1を図1に示す。油圧ショベル1は、ハイブリッド型の油圧ショベルであり、下部走行体2と、上部旋回体3と、作業機4と、キャブ5と、を備えている。なお、以下の説明において、「前」「後」「左」「右」とは、運転席に着座したオペレータを基準として決められる方向である。したがって、「左右方向」とは「車両幅方向」と同義である。
図2及び図3に、上部旋回体3を構成する旋回フレーム7と、旋回フレーム7に搭載された主な構成要素と、を示している。旋回フレーム7には、電装品としての発電機モータ21と、変換器としてのインバータ22と、蓄電器としてのキャパシタ23と、が搭載されている。なお、旋回フレーム7には、下部走行体2に支持された旋回モータや、旋回フレーム7に支持されたギア等から構成された旋回装置6が配置されている。
前述のように、2本のパワーケーブル40が発電機モータ21とインバータ22との間に接続されている。また、パワーケーブル40は、インバータ22、旋回装置6の旋回モータ、キャパシタ23の間にも設けられている。
キャブ5は左デッキ27の前方部分に配置されている。図5に示すように、キャブ5は、キャブ全体の枠を構成する枠フレーム5aと、枠フレーム5aに装着された外装5b、窓5c、ドア(図示せず)等から構成されている。また、キャブ5の内部には、図示していないが、運転席、操作レバー、表示用コントローラ、モニタ等が設けられている。そして、これらの各機器には電線が接続され、これらの電線は結束されてハーネス50としてキャブ5の底面5dから引き出されている。
ハーネス50は、前述のように、キャブ5の床の底面5dから下方に引き出され、車両後部に設けられたセンサや各種の電装品に接続されている。より詳細には、ハーネス50は、図4(キャブ5は省略している)及び図5の拡大部分図に示すように、キャブ5の床の底面5dから下方に引き出され(第1部分50a)、キャブ5の底面5dに沿って前方にかつキャブ5の外装側面5b(以下、単に側面と記す)より外方に延び(第2部分50b)、さらにキャブ5の側面5bに沿って上方に延び(第3部分50c)、そしてキャブ5の側面5bに沿って車両後方に延びている(第4部分50d)。
組立工程においてキャブ5を旋回フレーム7に搭載する場合は、図5に示すように、ハーネス50はブラケット52を介してキャブ5に予め取り付けられている。この状態で、キャブ5が旋回フレーム7の左デッキ27に搭載される。このとき、ハーネス50は、キャブ5の右側面5bとセンタフレーム26の左縦プレート31の間に配置される。そして、キャブ5が旋回フレーム7に搭載された後に、ハーネス50の後方に延びる部分を、クランプ59によって左縦プレート31の側面に固定する。
図7にキャブ5が旋回フレーム7に搭載されている状態を示している。キャブマウント(図示せず)の交換を行う際には、キャブ5を旋回フレーム7に固定しているボルト(図示せず)を取り外す。そして、リフトによってキャブ5を例えば200mm程度持ち上げる。図8にキャブ5が持ち上げられた状態を示している。このとき、ハーネス50はキャブ5に固定されたブラケット52に支持されている。またブラケット52にもっとも近い部分は簡易クランプ58によって支持されている。このため、簡易クランプ58や他のクランプ59を左縦プレート31から取り外すことなく、ハーネス50をキャブ5とともに上方に持ち上げることが可能である。したがって、マウントキャブの交換作業が非常に容易になる。
本実施形態の特徴をまとめると、以下の通りである。
本発明は以上のような実施形態に限定されるものではなく、本発明の範囲を逸脱することなく種々の変形又は修正が可能である。
