Milling and digging feeding system, milling and digging feeding method and milling and digging equipment
The invention provides a milling and excavating feeding system, a milling and excavating feeding method and milling and excavating equipment, and relates to the technical field of milling and excavating equipment. The milling and digging feeding system comprises a hydraulic execution element, a first proportional pressure regulating unit, a deviation rectifying oil cylinder, a second proportional pressure regulating unit, a working device and a transverse deviation rectifying structure; the hydraulic executive component is in driving connection with a mounting frame of the working device so as to lift the working device, the first proportional pressure regulating unit is arranged on a calibration oil section of the hydraulic executive component, and the calibration oil section is an oil return section of the hydraulic executive component when the working device descends due to gravity and reversely drags the hydraulic executive component; the transverse deviation rectifying structure is located below or on the side of a milling and digging assembly of the working device, the transverse deviation rectifying structure is movably connected with the mounting frame in the transverse direction, and the deviation rectifying oil cylinder is in driving connection with the mounting frame and the transverse deviation rectifying structure so that the transverse deviation rectifying structure can transversely move relative to the mounting frame till the transverse deviation rectifying structure can abut against the side wall of a groove to be milled and dug. And the second proportional pressure regulating unit is arranged on an oil inlet path of the deviation rectifying oil cylinder.
本发明提供一种铣挖进给系统、铣挖进给方法及铣挖设备，涉及铣挖设备技术领域。铣挖进给系统包括液压执行元件、第一比例调压单元、纠偏油缸、第二比例调压单元、工作装置和横向纠偏结构；液压执行元件与工作装置的安装架驱动连接，以使工作装置升降，第一比例调压单元设置于液压执行元件的标定油路段上，标定油路段为工作装置受重力下降并反拖液压执行元件时液压执行元件的回油路段；横向纠偏结构位于工作装置的铣挖总成的下方或侧方，横向纠偏结构与安装架在横向上可活动地连接，纠偏油缸分别与安装架和横向纠偏结构驱动连接，以使横向纠偏结构相对于安装架在横向运动直至与待铣挖槽的侧壁抵接，第二比例调压单元设置于纠偏油缸的进油油路上。
