Excavator walking automatic oiling device, control system and method
The invention discloses an excavator walking automatic oiling device, a control system and a method, and relates to the technical field of oiling. The device comprises an oil injection unit, the oil injection unit comprises an oil injection shell, an inner cavity of the oil injection shell is slidably connected with a compression piston, and the inner cavity of the oil injection shell of the compression piston is divided into a compression area and a driving area; the oil distributing unit comprises an oil way distributor, an oil distributing end cover, a transition pipe, an oil distributing and injecting pipe and a branch pipe connector. The oil injection system has the beneficial effects that starting and stopping of the pneumatic oil pump are controlled by adjusting the power supply time of the output end of the time relay, and then the oil injection time and the oil injection amount are adjusted; the lower end of an original walking lubricating oil pump contactor is directly connected with a three-phase air switch, and a time relay controls a pneumatic oil pump to achieve synchronous automatic starting and stopping of a walking mode and a walking mechanism oil injection system. Therefore, on one hand, the labor intensity of personnel is reduced, on the other hand, the lubricating effect and efficiency of the electric shovel walking mechanism are improved, meanwhile, grease waste is reduced, and the grease utilization rate is increased.
本发明公开了一种挖掘机行走自动注油装置、控制系统及方法，涉及注油技术领域。本发明包括注油单元，其包括注油壳，所述注油壳的内腔滑动连接有压缩活塞，所述压缩活塞注油壳的内腔将分隔成压缩区和驱动区；分油单元，包括油路分配器、分油端盖、过渡管、分注油管和分管连接头。本发明的有益效果：本发明通过调整时间继电器输出端给电时间而控制气动油泵的启停进而调节注油时间与注油量的注油系统；通过在原有的行走滑油泵接触器下端直连三相空开、时间继电器控制气动油泵而实现行走模式与行走机构注油系统的同步自动启停。因此，一方面降低了人员劳动强度，另一方面提高了电铲行走机构润滑效果和效率，同时减少了油脂浪费，提升油脂利用率。
