本考案はバツクホウ作業車のホース保護構造に
関する。[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a hose protection structure for a backhoe work vehicle.

Some wheel loaders, which are an example of backhoe work vehicles, have a backhoe device connected to the rear of the vehicle body in the following manner. That is, a pair of upper and lower slide frames extending in the left-right direction of the vehicle body is provided, and a pair of left and right connecting brackets are constructed and connected across the upper and lower slide frames, and the connecting brackets are connected to the vehicle body. A slide bracket equipped with a shovel arm is attached to a portion of the upper and lower slide frames opposite to the connection bracket so as to be slidable left and right.
前述のスライドブラケツトに支持されるシヨベ
ルアームには駆動用の油圧アクチユエータが備え
られており、車体側の油圧ポンプから油圧ホース

The shovel arm supported by the aforementioned slide bracket is equipped with a hydraulic actuator for driving, and it is necessary to extend a hydraulic hose from the hydraulic pump on the vehicle body side to the aforementioned hydraulic actuator.
この場合、スライドブラケツトがスライドフレ
ームに沿つて左右スライドするので、そのスライ
ド量の分だけ油圧ホースが長くなる。従つて、こ
の長い油圧ホースの配置が問題となつてくる。 In this case, since the slide bracket slides left and right along the slide frame, the hydraulic hose becomes longer by the amount of the slide. Therefore, the arrangement of this long hydraulic hose becomes a problem.
本考案は前記油圧ホースをコンパクトに、且
つ、スライドブラケツトをスライド操作しても支
障のないように配置することを目的としている。 The object of the present invention is to make the hydraulic hose compact and to arrange it so that there is no problem even when the slide bracket is slid.

は次のとおりである。
The feature of the present invention is that the above-mentioned backhoe work vehicle is constructed as follows. In other words, the hydraulic hose for the hydraulic actuator of the shovel arm is bent between the connection part of the slide frame and the connection part of the slide bracket to allow the left and right sliding of the slide bracket, and In addition, a cover is provided between both slide frames and between both connection brackets to prevent the hydraulic hose from protruding toward the connection bracket, and its functions and effects are as follows. It is as follows.
例えば、第１，２，４図に示すように上下一対
のスライドフレーム１１において、車体４側に連
結ブラケツト１４を取り付け、反対側にスライド
ブラケツト１２を取り付けると、上下のスライド
フレーム１１の間に比較的大きな空間が得られ
る。従つて、この空間内に長い油圧ホース１３を
屈曲させて配置してやれば、油圧ホース専用の空
間を別に設けなくてもよいのである。
For example, as shown in FIGS. 1, 2, and 4, in a pair of upper and lower slide frames 11, if the connection bracket 14 is attached to the vehicle body 4 side and the slide bracket 12 is attached to the opposite side, a comparison will occur between the upper and lower slide frames 11. A large space can be obtained. Therefore, if the long hydraulic hose 13 is bent and arranged in this space, there is no need to provide a separate space exclusively for the hydraulic hose.
以上のように、上下のスライドフレーム１１の

と、油圧ホース１３が左右の連結ブラケツト１４
の間に入り込めなくなるので、油圧ホース１３が
連結ブラケツト１４に引つ掛かるおそれもない。 As described above, when the slide bracket 12 is largely slid with the hydraulic hose 13 disposed between the upper and lower slide frames 11, the hydraulic hose 13 also moves together with the slide bracket 12, and a part of the hydraulic hose 13 is moved. may protrude toward the vehicle body 4 side and get caught on the connection bracket 14. However, when the cover 19 of the present invention is provided, the hydraulic hose 13 is connected to the left and right connecting brackets 14.
Since the hydraulic hose 13 cannot get caught between the connecting brackets 14, there is no risk of the hydraulic hose 13 getting caught on the connecting bracket 14.
以上のように、上下一対のスライドフレームの
間の空間を有効に利用して、この空間内に油圧ホ

クトにまとめることができた。
As described above, by effectively utilizing the space between the pair of upper and lower slide frames and arranging the hydraulic hose within this space, the structure around the hydraulic hose can be made more compact without creating a dedicated space for arranging the hydraulic hose. I was able to summarize it.
又、前述のように構成した場合に、油圧ホース
が連結ブラケツトに引つ掛つて破損すると言う弊
害の生ずるおそれがあるが、本考案ではカバーを
設けることによつてこの弊害を防止している。 Further, in the case of the above-mentioned structure, there is a risk that the hydraulic hose may get caught on the connection bracket and be damaged, but in the present invention, this problem is prevented by providing a cover.
以下、本考案の実施例を図面に基づいて説明す
