OPERATION LEVER DEVICE AND ACTUATOR SELECTION CIRCUIT FOR WORK MACHINE
PROBLEM TO BE SOLVED: To provide an operation lever device for a work machine capable of preventing erroneous operation as far as possible, and an actuator selection circuit for the work machine with the usage of the operation lever device.SOLUTION: An operation lever 17 is provided to be tiltable in a direction orthogonal to an operation direction. A guide plate 32 for regulating a posture of the operation lever 17 is provided on a housing of an operation valve 15. The guide plate 32 includes two guide grooves 32a and 32b arranged in parallel in the operation direction of the operation lever 17, and a connection groove 32c connecting intermediate parts thereof with each other. When the operation lever 17 is in the one guide groove 32b, a striker 41 provided on the operation lever 17 is abutted to an operation part 36a, and a changeover valve 36 is changed over. A selection valve 46 is changed over by changing over of the changeover valve 36, and one of two hydraulic actuators is selected as an operation target.SELECTED DRAWING: Figure 6
【課題】誤操作が可及的に防止できる構成の作業機用の操作レバー装置と、その操作レバー装置を用いた作業機用のアクチュエータ選択回路を提供する。【解決手段】操作レバー１７を、操作方向に対して直交する方向に傾動可能に設ける。操作バルブ１５のハウジングに、操作レバー１７の姿勢を規制するガイドプレート３２を設ける。ガイドプレート３２は、操作レバー１７の操作方向に並列に設けられた２本のガイド溝３２ａ，３２ｂと、その中間部どうしを連絡する連絡溝３２ｃとを有する。操作レバー１７が一方のガイド溝３２ｂ内にあるときに操作レバー１７に設けたストライカ４１が操作部３６ａに当接して切換えられる切換バルブ３６を設ける。切換バルブ３６の切換えにより選択バルブ４６が切換えられ、２つの油圧アクチュエータのうちの１つが操作対象として選択される。【選択図】図６
