曲して架設してあるバツクホウに関する。[Detailed description of the invention] [Industrial field of application] The present invention has an open boarding and operating section equipped with a group of operating levers and a driver's seat and an oil tank arranged side by side on the left and right sides of a swivel base, and A handrail is provided in front of the operating lever group of the boarding operation section and at approximately the same position as the front surface of the oil tank. The present invention relates to a backhoe in which a plurality of hydraulic hoses are connected to each other so as to be rotatable from side to side, and are bent and installed in an upright state across the backhoe device and a joint portion in front of the oil tank.
従来、上記バツクホウでは、バツクホウ装置の
上下揺動及び左右回動操作に伴つて、起立状態で
屈曲する油圧ホースが、操作レバー群の前部に設
けた手摺りとオイルタンクとの隙間から運転座席
側に入り込んで来るものであつた。
Conventionally, in the above-mentioned backhoe, the hydraulic hose that bends in the upright position as the backhoe device is swung up and down and rotated left and right is inserted into the driver's seat through the gap between the handrail and the oil tank provided in front of the control lever group. It was something that was coming into my side.
油圧ホースが、手摺りとオイルタンクとの隙間
から入り込んだ場合に、その油圧ホースが、オイ
ルタンクの搭乗運転部側で前端側のコーナーに引
つ掛かつて損傷する虞れがあつた。
If the hydraulic hose entered through the gap between the handrail and the oil tank, there was a risk that the hydraulic hose would get caught in the corner of the front end of the oil tank on the passenger side and be damaged.
本考案の目的は、油圧ホースが、オイルタンク
の前記コーナーに、ひつかからないようにする点
にある。 The purpose of the present invention is to prevent the hydraulic hose from getting caught in the corner of the oil tank.
本考案におけるバツクホウのホース保護構造の
特徴構成は、前記オイルタンクの前記搭乗運転部
側で前端側のコーナー近くに、前記手摺りの端部
を近接配置し、且つ、その手摺りの端部は、前記
オイルタンクに近づく程運転座席前方相当位置の
手摺り部分よりも後方側に傾斜させた点にあり、
その作用効果は、次の通りである。
The characteristic configuration of the backhoe hose protection structure of the present invention is that the end of the handrail is disposed close to the corner of the front end side of the boarding and operating section of the oil tank, and the end of the handrail is , at a point that is inclined more rearward than a handrail portion at a position corresponding to the front of the driver's seat as it approaches the oil tank;
Its effects are as follows.
つまり、オイルタンクの搭乗運転部側で前端側
のコーナ近くに、手摺りの端部を近接配置してあ
るために、油圧ホースに対抗する面又は油圧ホー
スと交わる方向の線が、オイルタンクの前面と手

としても、ほぼ連続する面又は線を形成するオイ
ルタンク前面や手摺りに阻止され、オイルタンク
のコーナーに油圧ホースが引つ掛かり難くでき
る。
In other words, because the end of the handrail is placed close to the front corner of the oil tank on the passenger side, the surface that opposes the hydraulic hose or the line that intersects with the hydraulic hose is It is formed almost continuously between the front side and the handrail, and the hydraulic hose is
Even if an attempt is made to enter through the gap between the handrail and the oil tank, the oil tank is blocked by the front surface of the oil tank and the handrail which form a substantially continuous surface or line, thereby making it difficult for the hydraulic hose to get caught in the corner of the oil tank.
しかも、手摺りの端部が、運転座席前方相当位
置の手摺り部分よりもオイルタンクに近づく程後
方側に傾斜されているため、ブームが起き上がり
ながら運転座席側に近づいてくるとき、その油圧
ホースが、オイルタンク前面側に近づくように、
つまり、機体横外側部に案内されて、運転座席の
前方位置から横側方へ外れるように移動して、操
縦視界が良くなる。 Moreover, the end of the handrail is slanted further back toward the oil tank than the part of the handrail located in front of the driver's seat, so when the boom approaches the driver's seat while rising, the hydraulic hose is closer to the front side of the oil tank.
In other words, it is guided by the lateral outer part of the fuselage and moves from the position in front of the driver's seat to the lateral side, improving the visibility of the operation.
従つて、バツクホウ装置を自由に上下揺動及び
左右回動操作しても、油圧ホースがオイルタンク

で、良好に駆動操作できるに至つた。
Therefore, even if the backhoe device is freely swung up and down and rotated left and right, the hydraulic hose is less likely to get caught in the corners of the oil tank, so damage to the hydraulic hose can be suppressed. It has now been possible to operate the device satisfactorily over a long period of time without oil leakage.
