A hydraulic component support member that is connected to each of the frame members and supports a predetermined hydraulic component is integrally provided.

このように構成した本発明は、一対のエンジン支持部材の一方の外側部分となる箇所に一体に油圧部品支持部材を設けたことから、従来では他の場所に設置されていた所定の油圧部品を、この油圧部品支持部材付近に配置することができる。したがって、一対のエンジン支持部材の一方の外側部分となる箇所付近のデッドスペースを所定の油圧部品の配置スペースとして有効に活用できると共に、所定の油圧部品が設置されていたスペースの削減が可能となる。また、油圧部品支持部材が、一対のエンジン支持部材の一方に対する補強部材、及びテールフレームの補強部材を兼ねることから、エンジンの安定保持を実現できると共に、大きな強度を有するテールフレームを実現できる。 In the present invention configured as described above, since the hydraulic component support member is integrally provided at a location which is one outer portion of the pair of engine support members , a predetermined hydraulic component which has been conventionally installed at another location is provided. The hydraulic component supporting member can be disposed in the vicinity of the hydraulic component supporting member. Therefore, it is possible to effectively use the dead space near the portion that becomes one of the outer portions of the pair of engine support members as an arrangement space for the predetermined hydraulic component, and it is possible to reduce the space in which the predetermined hydraulic component is installed. . In addition, since the hydraulic component support member also serves as a reinforcing member for one of the pair of engine support members and a reinforcing member for the tail frame, it is possible to realize stable engine holding and a tail frame having high strength.

また本発明は、上記発明において、上記油圧部品支持部材と上記所定の油圧部品との間に、上記所定の油圧部品を保持する台座を備えたことを特徴としている。   Further, the present invention is characterized in that in the above invention, a pedestal for holding the predetermined hydraulic component is provided between the hydraulic component support member and the predetermined hydraulic component.

このように構成した本発明は、所定の油圧部品を台座を介して、油圧部品支持部材によって安定して保持、例えば水平保持させることができる。   In the present invention configured as described above, a predetermined hydraulic component can be stably held, for example, horizontally, by the hydraulic component support member via the pedestal.

このように構成した本発明は、当該建設機械によって実施される作業に伴ってエンジン支持部材部分にかかる負荷による油圧部品支持部材の変形を切り欠きを介して滑らかに進行させることができ、作業中の負荷による油圧部品支持部材部分の破損を防止できる。   The present invention configured as described above can smoothly advance the deformation of the hydraulic component support member due to the load applied to the engine support member portion through the notch in accordance with the work performed by the construction machine. It is possible to prevent the hydraulic component support member from being damaged due to the load.

また本発明は、上記発明において、上記テールフレームが、その底部に、上記油圧部品支持部材に対する上記所定の油圧部品の着脱を可能にする穴を有することを特徴としている。   The present invention is characterized in that, in the above-mentioned invention, the tail frame has a hole at a bottom portion thereof that allows the predetermined hydraulic component to be attached to and detached from the hydraulic component support member.

このように構成した本発明は、テールフレームの底部の穴を介して、所定の油圧部品の交換を容易に行なうことができる。   According to the present invention configured as described above, a predetermined hydraulic component can be easily replaced through a hole at the bottom of the tail frame.

また本実施形態は特に、図２，５等に示すように、エンジンブラケット６の外側部分となる箇所に一体に例えば溶接され、所定の油圧部品例えばコントロールバルブ１０を支持する油圧部品支持部材７を備えている。この油圧部品支持部材７は、エンジンブラケット６の補強部材を兼ねると共に、図５等に示すようにその両端がＩビーム３の側板３ａ、Ｉビーム４の側板４ａに例えば溶接されていて、テールフレーム２の補強部材も兼ねている。油圧部品支持部材７の両端付近には例えば半円形状の応力集中を緩和させる切り欠き７ａ，７ｂをそれぞれ形成してある。 Further, in the present embodiment, as shown in FIGS. 2 and 5 and the like, a hydraulic component support member 7 for supporting a predetermined hydraulic component, for example, the control valve 10, is integrally welded to a portion to be an outer portion of the engine bracket 6. I have. The hydraulic component support member 7 also serves as a reinforcing member for the engine bracket 6 and, as shown in FIG. 5 and the like, both ends thereof are welded to the side plate 3a of the I beam 3 and the side plate 4a of the I beam 4, for example. 2 also serves as a reinforcing member. In the vicinity of both ends of the hydraulic component support member 7, for example, notches 7 a and 7 b that relieve stress concentration in a semicircular shape are formed.

図２等に示すように、油圧部品支持部材７とコントロールバルブ１０との間には台座８を配置してあり、センタフレーム１の底部とコントロールバルブ１０との間にも台座９を配置してある。台座８は油圧部品支持部材７に例えばボルトによって固定してあり、台座９はセンタフレーム１の底部に例えばボルトによって固定してある。これらの台座８，９によって例えばコントロールバルブ１０は、テールフレーム２の底部にほぼ平行となるように水平保持されている。   As shown in FIG. 2 and the like, a pedestal 8 is disposed between the hydraulic component support member 7 and the control valve 10, and a pedestal 9 is also disposed between the bottom of the center frame 1 and the control valve 10. is there. The pedestal 8 is fixed to the hydraulic component support member 7 with, for example, bolts, and the pedestal 9 is fixed to the bottom of the center frame 1 with, for example, bolts. For example, the control valve 10 is horizontally held by these bases 8 and 9 so as to be substantially parallel to the bottom of the tail frame 2.
