REMOTE CONTROL DEVICE FOR CONSTRUCTION MACHINE
To provide a remote control device for a construction machine capable of easily operating a pilot valve with high accuracy.SOLUTION: A hydraulic shovel includes a pilot valve 5, and an operation lever mounting part 53 that can mount/unmount an operation lever. A remote control device includes a support member 21, an electric actuator 23, and a drive transmission member 25. The support member 21 is installed above the operation lever mounting part 53. The electric actuator 23 is configured to be vertically drivable by having an upper end side supported by the support member 21. The drive transmission member 25 has an arm 251 connectable to the electric actuator 23. The electric actuator 23 is arranged at a front side of the operation lever in a horizontal operation direction by being mounted to a mounting hole of the support member 21. Vertical drive by the electric actuator 23 is transmitted to the operation lever mounting part 53 as an operation in a forward/backward operation direction through the arm 251 connected to the electric actuator 23.SELECTED DRAWING: Figure 7
【課題】パイロットバルブを簡易かつ高精度に操作することが可能な建設機械の遠隔操作装置の提供。【解決手段】油圧ショベルは、パイロットバルブ５と、操作レバーを脱着可能な操作レバー取付部５３とを備える。遠隔操作装置は、支持部材２１と電動アクチュエータ２３と駆動伝達部材２５とを備える。支持部材２１は、操作レバー取付部５３の上方に設置される。電動アクチュエータ２３は、上端側が支持部材２１に支持され、上下駆動可能に構成される。駆動伝達部材２５は、電動アクチュエータ２３に連結可能なアーム２５１を有する。電動アクチュエータ２３は、支持部材２１の取付穴に取り付けられることで操作レバーの左右操作方向の前側に配置される。電動アクチュエータ２３による上下駆動は、電動アクチュエータ２３に連結されたアーム２５１を介して操作レバー取付部５３に前後操作方向の操作として伝達される。【選択図】図７
