Oil cylinder protection plate device and hydraulic excavator
The invention discloses an oil cylinder protection plate device and a hydraulic excavator. The oil cylinder protection plate device comprises a hinge mechanism, a fixing mechanism, a protection plate mechanism and a supporting mechanism. The hinge mechanism comprises pin shafts rotationally connected with the tail end of a piston rod of an oil cylinder, the fixing mechanism comprises L-shaped plates, the protection plate mechanism comprises protection plate bodies arranged above the oil cylinder, one end of each L-shaped plate is rotationally connected with the corresponding pin shaft, the other end of each L-shaped plate is fixedly connected with the corresponding protection plate body, and a sliding groove is formed in the face, facing the oil cylinder, of each guard plate body. The supporting mechanism comprises a hoop installed outside an oil cylinder barrel, a vertical plate connected with the hoop and sliding pieces installed on the two sides of the vertical plate, and the sliding pieces are arranged in the sliding grooves and can slide along the sliding grooves. When the oil cylinder stretches out and draws back, the protection plate mechanism is always parallel to the installation plane of the oil cylinder, and the distance is unchanged. The protection plate bodies can freely move along with stretching and retracting of the oil cylinder, the whole oil cylinder is effectively protected, universality is high, the structure is simple, and the manufacturing cost is low.
本发明公开了一种油缸护板装置及液压挖掘机，包括铰接机构、固定机构、护板机构和支撑机构；铰接机构包括与油缸活塞杆末端转动连接的销轴，固定机构包括L型板，所述护板机构包括设于油缸上方的护板体，L型板的一端与销轴转动连接，另一端与护板体固定连接，所述护板体面向油缸的一面设有滑槽；支撑机构包括安装于油缸缸筒外部的卡箍、与卡箍相连的立板以及安装于立板两侧的滑动件，所述滑动件设于滑槽内且能够沿滑槽滑动；油缸伸缩时，护板机构始终与油缸的安装平面平行且距离不变。本发明的护板体能够随油缸伸缩而自由活动，有效保护油缸整体，通用性强，且结构简单，制造成本低。
