Description

油圧ショベルの高層建造物解体仕様機のハイリフトブームとローディングショベルのブーム等、又はカウンターウエイトよるメンテナンス向上機構Maintenance excavation mechanism by high lift boom and loading excavator boom of hydraulic excavator high-rise building demolition specification machine, or counterweight

本発明はブームと燃料タンクとの一体化、又はカウンターウエイトと油圧作動油タンクの一体化である。The present invention is an integration of a boom and a fuel tank, or an integration of a counterweight and a hydraulic fluid tank.

従来の油圧ショベルの構造は実用上十分であるが運転室本体回りでは様々な機器類が密集独立配置されている。The structure of a conventional hydraulic excavator is practically sufficient, but various devices are densely and independently arranged around the cab main body.

従って運転室本体回りでの油圧配管ホース類又はＯリング類の破損に対し油圧作動油タンクと燃料タンクが瞬時な対応の妨げになっており重機作業停止直後では油圧機器類の温度は高温となっている。これによってメンテナンス員に対し火傷、はさまれ等の危険性が伴うTherefore, the hydraulic oil tank and the fuel tank hinder the instantaneous response to damage to the hydraulic piping hoses or O-rings around the cab body, and the temperature of the hydraulic equipment becomes high immediately after the heavy machinery operation is stopped. ing. This causes dangers such as burns and pinching to maintenance personnel.

これらの状況判断により他の部分を分解する必要性が発生すると共に時間的にもコストがかかる。従って重機作業能率低下にもつながる。These situation judgments cause the necessity of disassembling other parts, and are time consuming. Therefore, the work efficiency of heavy machinery is reduced.

解決しようとする問題点は運転室本体回りに対しメンテナンス空間が狭ますぎる点である。The problem to be solved is that the maintenance space is too narrow relative to the cab main body.

課題を解決しようとする課題The challenge to solve the problem

本発明はメンテナンス空間を拡げるため図１に示す▲３▼油圧作動油タンクを▲５▼カウンターウエイトへ、又は▲４▼燃料タンクを▲１▼継ぎ足しブーム、▲２▼ストレートブームに移動一体化した事を最も主要な特徴とするIn the present invention, in order to expand the maintenance space, (3) hydraulic hydraulic oil tank shown in FIG. 1 is moved and integrated into (5) counterweight, or (4) fuel tank is added to (1) boom and (2) straight boom. Things are the main feature

発明の効果The invention's effect

図４に示す各部移動一体化により運転室本体回りは空間が生まれメンテナンス向上につながり、燃料タンクと一体化されたブーム内部には液体燃料が投載可能となり、これに対しブームの金属疲労による亀裂等の目視確認が可能となった。（亀裂が有れば内部の燃料が表ににじみ出る）The movement of each part shown in Fig. 4 creates a space around the cab body, which improves maintenance and allows liquid fuel to be placed inside the boom integrated with the fuel tank. Etc. can be visually confirmed. (If there is a crack, the internal fuel will ooze out.)

本発明により独立配置されていた燃料タンク又は油圧作動油タンクは不要となり工場生産ライン等も一部不必要となった。これにより大幅な生産コスト削減を可能とした。The fuel tank or hydraulic oil tank that has been independently arranged according to the present invention is no longer necessary, and part of the factory production line is unnecessary. This has made it possible to significantly reduce production costs.

本発明での一体化とする目的を最小の部品点数で原型を損なわずに実現した。The object of integration in the present invention was realized with the minimum number of parts and without damaging the prototype.

本発明は小改造にてコスト削減し、メンテナンス向上を計ると共に多機種に適用を可能とした。The present invention reduces the cost by a small modification, improves maintenance, and can be applied to many models.

なおローディングショベルのブームと高層建造物解体仕様機のハイリフトブームは基本的に同じ構造である。従ってローディングショベルのブーム等の詳細説明は省略する。
又、ローディングショベルのカウンターウエイト等も図３示す、事により詳細説明は省略する。The loading shovel boom and the high lift boom of the high-rise building dismantling machine have basically the same structure. Therefore, detailed description of the boom of the loading shovel is omitted.
The loading weight of the loading excavator is also shown in FIG.
