DRIVING DEVICE FOR WORK MACHINE
PROBLEM TO BE SOLVED: To provide a driving device for a work machine capable of averaging the life of hydraulic pumps without performing data measurement relating to the operation of the hydraulic pumps and/or calculation of cumulative amount of work.SOLUTION: The present invention relates to a driving device for a work machine comprising a plurality of hydraulic pumps, a plurality of hydraulic actuators, and a plurality of switching valves capable of connecting one hydraulic pump to one hydraulic actuator, wherein the driving device includes a connection order changing section that takes a plurality of priority tables and an interval time from a change interval time storage unit, measures a time, and changes a priority table to be output when a time has reached the interval time, and a working pump calculation section that takes a requested flow rate, a number of required pumps, and a priority table outputted by the connection order changing section, calculates assignment of a plurality of hydraulic pumps to the plurality of hydraulic actuators based on the number of required pumps, and outputs a command signal to a plurality of regulators and the plurality of switching valves based on the result of the assignment.SELECTED DRAWING: Figure 4
【課題】各油圧ポンプの動作に関するデータ計測や累積仕事量の演算を行わずに、各油圧ポンプの寿命の平均化を図ることのできる作業機械の駆動装置を提供する。【解決手段】複数の油圧ポンプと複数の油圧アクチュエータと、１つの油圧ポンプを１つの油圧アクチュエータに接続可能とする複数の切換弁とを備えた作業機械の駆動装置であって、複数の優先テーブルと、変更間隔時間記憶部からの間隔時間とを取り込み、計時して間隔時間に到達したときに、出力する優先テーブルを変更する接続順番変更部と、要求流量と要求ポンプ個数値と、接続順番変更部が出力する優先テーブルとを取り込み、要求ポンプ個数値を基に、複数の油圧ポンプの複数の油圧アクチュエータへの割当てを算出し、割当ての結果を基に、複数のレギュレータ及び複数の切換弁に対する指令信号を出力する使用ポンプ演算部とを備えた。【選択図】 図４
