GREASING SYSTEM FOR CONSTRUCTION MACHINE
To provide a greasing system for a construction machine capable of adequately greasing a pin bearing portion correspondingly to grease consumption of the pin bearing portion regardless of operation status of the construction machine.SOLUTION: Pin load acting on a pin bearing portion 29 and a pin rotation angle, of an operation device 10 of a hydraulic backhoe 1 are detected with sensors 37 and 38. Grease consumption g is accumulated as accumulated grease consumption G by sequentially calculating the grease consumption g based on the pin load and the pin rotation angle detected with the sensors 37 and 38 (S4, 5), after the accumulated grease consumption G showing a leaking amount of grease from the pin bearing portion 29 is reset (S3) upon activating the hydraulic backhoe 1. When the accumulated grease consumption G reaches a first determined consumption G1 which requires greasing to the pin bearing portion 29 (Yes at S6), the pin bearing portion 29 is greased at the amount corresponding to the first determined consumption G1 (S8).SELECTED DRAWING: Figure 4
【課題】作業装置の作動状態に関わらずピン支承部のグリス消費に対応して適切にピン支承部への給脂を実行できる建設機械の給脂システムを提供する。【解決手段】油圧ショベル１の作業装置１０のピン支承部２９に作用するピン荷重及び回動角度をセンサ３７，３８により検出する。油圧ショベル１の稼働が開始されると、ピン支承部２９からのグリスの漏れ量を表す累積グリス消費量Ｇをリセットした上で（Ｓ３）、各センサ３７，３８により検出されたピン荷重及びピン回動角度に基づきグリス消費量ｇを逐次演算して、累積グリス消費量Ｇとして累積する（Ｓ４，５）。累積グリス消費量Ｇがピン支承部２９への給脂を要する第１判定消費量Ｇ1に達すると（Ｓ６がＹes）、第１判定消費量Ｇ1に対応する量のグリスをピン支承部２９に給脂する（Ｓ８）。【選択図】図４
