Description

油压式建筑机械的操作方式选择装置及方法
本发明涉及油压式建筑机械的操作方式选择装置及方法，特别涉及这样一种油压建筑机械的操作方式选择装置及方法，即，操作者能将操作杆和与其对应的各油压促动器的相应电子比例阀的连动关系设定为最便于使用的连动关系，从而操作者能根据作业环境或状况进行设定而容易地操作装备。
在日本专利公报特开平3-61811号中揭示了一种操作杆和操作阀的连动关系可变更的挖掘机等油压式建筑机械，该机械中设有左右一对可分别前后及左右滑动的操作杆，通过操作对应于油压促动器的电子比例阀来改变连动关系，上述各油压促动器用于与该操作杆的前后左右滑动连动的旋转操作、悬臂操作、摇臂操作及铲斗操作。
该现有技术中，操作杆和电子比例阀为电气连接，装在两者中间的控制器内的储存机构中预先储存着操作杆和电子比例阀的若干种连动关系，从这些连动关系中用输入机械指示依次所需的连动关系，变更为操作者最易使用的连动关系。
但是，上述现有技术中，操作者所能选择的连动关系只是控制器内储存着的各种连动关系中的一种，因操作者的习惯或作业条件的变化等，有时需要预先设定的连动关系以外的连动关系，该现有技术不能适应这种情形。
因此，本发明的目的在于提供一种油压式建筑机械的操作方式选择装置及方法，该装置及方法能使操作者能按自已所需地设定操作杆和电子比例阀的连动关系，操作者可选择更为方便的操作方式，能极大地提高装备运用效率。
为了实现上述目的，本发明的油压式建筑机械的操作方式选择装置，设有若干可分别前后左右滑动的操作杆，还设置着与上述操作杆的滑动分别连动的电位计，由电位计送出的电气信号控制梁、悬臂、铲斗及摇臂等多关节作业装置；其特征在于，备有操作方式选择开关、控制器和显示机构；
操作方式选择开关为开状态时，可以设定上述操作杆和与其操作量成正比动作的上述电子比例阀的新连动关系，该新连动关系不同于原有连动关系；
控制器在操作方式选择开关为开状态时，按预定顺序设定新连动关系，将设定的连动关系储存起来，用该连动关系控制上述作业装置；
显示机构将上述选择开关的功能和控制器功能显示在外部，以便操作者容易看到。
本发明还提供油压式建筑机械的操作方式选择方法，该油压建筑机械备有若干个操作杆、将上述操作杆的物理操作量转换为电气量的电位计和控制器，上述控制器根据电位计的信号操作梁、臂、铲斗及摇臂等作业装置操作用电子比例阀，其特征在于，在执行操作方式选择功能的操作方式选择开关为开的状态时，由控制器选择上述作业装置的各种作业动作之一，并由显示机构显示在外部，当操作了操作杆时，将该操作信号输入并决定操作杆的协调关系，储存在上述控制器内的储存装置中，依次决定并储存对于其余作业装置的操作杆的协调关系，完成新的操作方式的转换。
图1是概略地表示本发明油压式建筑机械的操作方式选择装置的简图。
下面，参照附图说明本发明的最佳实施例。
图1是概略地表示本发明一实施例油压式建筑机械的操作方式选择装置的简图。
如图1所示，本发明油压式建筑机械的操作方式选择装置备有一对操作杆1、电位计2、控制器4、电子比例阀5和控制阀6。操作杆1在操作者的操作力作用下可分别前后及左右地滑动；电位计2分别设在这些操作杆上，与操作杆操作方向的前后及左右滑动连动并发出电气信号；控制器4根据电位计2的信号操作作业装置；电子比例阀5产生与控制器输出的信号成正比的预定控制压；控制阀6调节供给动作器7的动作油压，该动作油压在电子比例阀的控制压作用下从主泵排出而供给动作器7。操作方式选择开关3连接在控制器4上，该选择开关3在开状态时，可设定操作杆和与其操作量成正比动作的电子比例阀的与原有连动关系不同的新连动关系。还设置了液晶显示或CRT显示等显示机构8，在外部显示控制器的功能，操作者可容易地辨认现在的操作方式。
上述控制器由输入接口4a、只读存储器(ROM)4b及随机存取存储器(RAM)4e、中央处理器(CPU)4c、AMP电路4d和输出接口4f构成。输入接口4a用于输入电位计的电压信号和操作方式选择开关的开/关信号；只读存储器(ROM)4b及随机存取存储器(RAM)4e输入及设定储存操作杆和各电子比例阀的若干连动关系的数据；中央处理器(CPU)4c根据操作者的操作信号和ROM及RAM设定的连动关系进行计算处理；AMP电路4d根据由中央处理器输出的信号输出电流信号；输出接口4f将该AMP输出的电流信号输出到电子比例阀5。
下面说明本实施例的动作。
操作者用操作杆1驱动装置期间，当操作方式选择开关3为开时，可设定操作杆1与相对于各动作器7的电子比例阀5的新的连动关系。
即，当操作方式选择开关3为开时，在ROM4b选择各作业装置7动作种类中的任一种，例如悬臂7a上升时，指示给CPU4c用显示机构8显示“BMU”。操作者用操作杆进行悬臂上升的操作时，被操作的操作杆的操作信号输入到RAM4e。另外，当悬臂7a下降时，显示机构8显示“BMD”，操作杆相应动作时，被操作的操作杆的操作信号输入到RAM4e。继续按该顺序进行，决定操作杆应操作的悬臂7b、铲斗7c及摇臂7d的动作信号，已决定的操作杆的协调关系由RAM4e储存，根据储存的协调关系ROM4b向CPU4c发出指示，使CPU4c进行计算动作，这样，操作者可设定新的连动方式。
如上所述，根据本发明的油压式建筑机械的操作方式选择装置及方法，操作者可以按自已的需要设定操作杆与电子比例阀的连动关系，操作者选择更为方便的操作方式，能极大提高装备运用的效率。
