Description

この発明は建設機械のハウスフレーム及び手摺り構造の技術分野に属する。更に詳細には、燃料タンクの点検等を容易にしたハウスフレーム兼用の手摺り構造の技術に関する。 The present invention belongs to the technical field of house frames and handrail structures for construction machines. More specifically, the present invention relates to a handrail structure that also serves as a house frame that facilitates inspection of a fuel tank.

油圧ショベル等の建設機械では、下部走行体の上に上部旋回体を旋回自在に載置すると共に、上部旋回体の床上にエンジン、油圧ポンプ等の油圧機器や燃料タンクなどを収納するためにハウスを設け、ハウスの内側にこれらの機器や燃料タンクを保管することが行われている。このために、上部旋回体の床上又は基台の上にハウスフレームを立設して、このハウスフレームにハウスカバーを取り付けてハウスを構成する事が行われている。一方、エンジンや油圧ポンプ等の油圧機器や燃料タンク等は点検やメンテナンスをする必要がある。従って、メンテナンス作業に便利な適宜の位置にステップ(踏み台)を設けると共に、ステップの近くに手摺りを設けて上部旋回体の床上への昇降を容易にし、安全を図っていた。 In a construction machine such as a hydraulic excavator, an upper swing body is pivotably mounted on a lower traveling body, and a house for storing hydraulic equipment such as an engine and a hydraulic pump and a fuel tank on the floor of the upper swing body. The equipment and the fuel tank are stored inside the house. For this purpose, a house frame is constructed by standing a house frame on the floor or base of the upper swing body and attaching a house cover to the house frame. On the other hand, hydraulic equipment such as engines and hydraulic pumps, fuel tanks, etc. need to be inspected and maintained. Therefore, a step (stepping platform) is provided at an appropriate position convenient for maintenance work, and a handrail is provided near the step to facilitate the raising and lowering of the upper revolving structure on the floor for safety.

ステップの近くに手摺りを設けた従来例としては、例えば、特許文献1に開示されているものがある。この文献に記載されている手摺りはステップの近くのハウス内部に把持する部分が突起した状態で取り付けられている。更にハウスの天井部にも第2の手摺りを設けている。又、特許文献2には、運転室の前方に作業用のステップを設けると共に該ステップの前側縁部に沿って把持する部分が突起した手摺りを設けている。

As a conventional example in which a handrail is provided near the step, for example, there is one disclosed in Patent Document 1. The handrail described in this document is attached in a state in which the gripped portion protrudes inside the house near the step. Further, a second handrail is provided on the ceiling of the house. Further, in Patent Document 2, a working step is provided in front of the operator's cab, and a handrail with a protruding portion protruding along the front side edge of the step is provided.

しかし、従来の建設機械には、燃料タンクの近くには手摺りが設けられていなかった。燃料タンクは点検作業や給油作業のために頻繁にアクセスする必要があるが、燃料タンクの周囲には油圧ポンプ等の油圧機器類が多数配置されており、突起部分を有する手摺りを設けると逆に手摺りの突起部分が作業の邪魔になる可能性がある。本発明は、上記問題を解決するためになされたものである。 However, the conventional construction machine has not been provided with a handrail near the fuel tank. The fuel tank needs to be accessed frequently for inspection and refueling operations, but there are many hydraulic equipment such as a hydraulic pump around the fuel tank. In addition, the protruding part of the handrail may interfere with the work. The present invention has been made to solve the above problems.

本発明は上記の課題を解決するための手段として以下の構成を採用している。即ち、請求項1に記載の発明は、
建設機械の上部旋回体のフロアに燃料タンクやサンプタンクを収納するハウスを設けた建設機械において、前記燃料タンクやサンプタンク、並びにそれ等の付属品を前記上部旋回体の右前側フロア上に配置すると共に、前記燃料タンクやサンプタンク、並びにそれ等の付属品のメンテナンス時にアクセス容易な箇所であって前記燃料タンクの外側方に位置するハウスフレームの一部をハウス側面カバーの上縁から突出するように設け、該ハウスフレームの一部を手摺として兼用可能な構成としたことを特徴としている。
The present invention employs the following configuration as means for solving the above-described problems. That is, the invention described in claim 1
In a construction machine provided with a house for storing a fuel tank or sump tank on the floor of the upper swing body of the construction machine, the fuel tank, sump tank, and their accessories are arranged on the right front floor of the upper swing body. In addition, a part of the house frame that is easily accessible during maintenance of the fuel tank, sump tank, and their accessories and that is located outside the fuel tank protrudes from the upper edge of the house side cover. And a part of the house frame can be used as a handrail.

また、請求項2に記載の発明は、請求項1に記載の発明において、前記ハウスフレームの一部は、手摺り用として、丸パイプ又は丸棒材で構成したことを特徴としている。 The invention according to claim 2 is characterized in that, in the invention according to claim 1, a part of the house frame is constituted by a round pipe or a round bar for handrails.

本発明はハウスフレームの一部を手摺りとして兼用可能に構成したことにより、燃料タンクやサンプタンク、並びにそれ等の付属品のメンテナンス作業や給油作業が安全、かつ容易に行えるという効果が得られる。 Since the present invention is configured so that a part of the house frame can be used as a handrail, the maintenance and refueling operations of the fuel tank, sump tank, and their accessories can be performed safely and easily. .

以下本発明の実施形態を図に基づいて説明する。図1は、本発明を実施した建設機械のハウスフレーム構造で、ハウスカバーを取り外した例を示す。図2は、ハウスカバーを取り付けた例を示す。図1,図2において、上部旋回体11の上側面にハウスフレーム12が立設され、ハウスカバー13はネジ類によりハウスフレーム12に取り付けられている。ハウスカバー13は、ハウス側面カバー13a、ハウス前面カバー13b及びハウス前方上部カバー13c及びハウス後方上部カバー13dから構成されている。ハウス側面カバー13a、前面カバー13bはネジ等により固定され、取り外し可能に構成されている。また、ハウス前方上部カバー13cは開閉自在に構成されている。ハウス後方上部カバー13dはネジ等により固定されている。また、燃料タンク15やサンプタンク17はハウスフレーム12に固定され、ハウスカバー13の内部に収納されている。また、燃料タンク15やサンプタンク17の付属品、例えば、フィルタ類(図示省略)もそれ等の近くに配置されている。ハウスフレーム12の一部16は丸パイプで構成され、手摺りとして利用できる程度の太さの直径のパイプで構成されている。燃料タンク15のキャップ15bは丸パイプ16に近接した位置に設けられている。 Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 shows an example in which a house cover is removed from a house frame structure of a construction machine embodying the present invention. FIG. 2 shows an example in which a house cover is attached. 1 and 2, a house frame 12 is erected on the upper side surface of the upper swing body 11, and a house cover 13 is attached to the house frame 12 with screws. The house cover 13 includes a house side cover 13a, a house front cover 13b, a house front upper cover 13c, and a house rear upper cover 13d.
