〔産業上の利用分野〕
本考案は、バツクホウ作業用アームを左右回動
操作自在に取付け、前記アームを駆動する油圧シ
リンダに対する油圧ホースを、旋回台又は車体の
前端部から前記アームの側面にわたつて起立状態
で屈曲して架設してあるバツクホウに関する。[Detailed description of the invention] [Industrial application field] The present invention mounts a backhoe work arm so that it can be rotated left and right, and connects a hydraulic hose to a hydraulic cylinder that drives the arm to the front end of the swivel base or the vehicle body. The present invention relates to a backhoe which is bent and installed in an upright state over the side surface of the arm.
従来、上記バツクホウでは、アームの角部が、
油圧ホースに対して露出した状態で対向してい
た。
Conventionally, in the above-mentioned backhoe, the corner of the arm is
It was exposed and facing the hydraulic hose.
しかし、前記油圧ホースは、アームが左右回動
できるように、大きく余裕をもつた起立状態に屈
曲させてあるために、アームを大きく左右に回動
操作するに伴つて、アーム側面視で油圧ホースと
交差するアームのとがつた角部に、油圧ホースが
摺接して、油圧ホースが損傷する危険性があつ
た。
However, since the hydraulic hose is bent into an upright position with a large margin so that the arm can rotate left and right, as the arm is rotated left and right, the hydraulic hose is There was a risk that the hydraulic hose would come into sliding contact with the sharp corner of the arm that intersects with the arm, causing damage to the hydraulic hose.
本考案の目的は、アームの角部に油圧ホースが
摺接しないようにする点にある。 The purpose of the present invention is to prevent the hydraulic hose from coming into sliding contact with the corner of the arm.
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、アームの角部のうちアーム側面視で
油圧ホースと交差するものに、前記アームの電気
配線に対する保護用丸パイプを沿わせて配置して
あることにあり、その作用効果は、次の通りであ
る。
The characteristic configuration of the back hose protection structure of the present invention is that a protective round pipe for the electrical wiring of the arm is placed along the corner of the arm that intersects the hydraulic hose when viewed from the side of the arm. Its functions and effects are as follows.
つまり、アームを左右回動操作するに伴つて、
アーム側面視で油圧ホースと交差するアームの角
部に、油圧ホースが摺接しようとしても、その油
圧ホースは、アームの電気配線に対する保護用丸
パイプの曲面で受け止められる。
In other words, as the arm is rotated left and right,
Even if the hydraulic hose tries to come into sliding contact with the corner of the arm that intersects with the hydraulic hose when viewed from the side of the arm, the hydraulic hose is received by the curved surface of the protective round pipe for the electrical wiring of the arm.
従つて、本来アームに設けられていた丸パイプ
の配置を工夫するだけの安価で簡単な改造によつ
て、油圧ホースがアームのとがつた角部に摺接し
て損傷することを確実に回避でき、長期にわたつ
て油もれのないアームの良好な駆動操作を維持で
きるようになつた。
Therefore, by simply modifying the arrangement of the round pipe that was originally provided on the arm, it is possible to reliably avoid damage caused by the hydraulic hose sliding against the sharp corners of the arm. , it has become possible to maintain good drive operation of the arm without oil leakage over a long period of time.
