一种液压挖掘机油缸防护装置及液压挖掘机
摘要：
本发明公开了一种液压挖掘机油缸防护装置及液压挖掘机，包括支架机构和防护板机构，支架机构以轴向方向布置在油缸缸体外表面上，且支架机构固定在油缸缸体上；防护板机构滑动连接在支架机构上，且防护板机构一端与油缸活塞杆端部固定连接；当油缸活塞杆完全处于收缩状态时，防护板机构位于油缸缸体上，当油缸活塞杆运动时，防护板机构随着油缸活塞杆一起移动，用以实现对伸出的油缸活塞杆进行连续性防护。本发明使用方便，效果明显，通过本装置可对液压挖掘机油缸进行有效防护，极大地提高工作安全性，减少故障，降低维修保养成本。
摘要（英）：

The invention discloses a hydraulic excavator oil cylinder protection device and a hydraulic excavator. The device comprises a support mechanism and a protection plate mechanism, wherein the support mechanism is arranged on the outer surface of an oil cylinder body in the axial direction, and is fixed on the oil cylinder body, the protection plate mechanism is connected with the support mechanismin a sliding mode, one end of the protection plate mechanism is fixedly connected with the end part of a piston rod of an oil cylinder, when the piston rod of the oil cylinder is completely in the contracted state, the protection plate mechanism is located on the oil cylinder body, and when the piston rod of the oil cylinder moves, the protection plate mechanism moves along with the piston rod ofthe oil cylinder so as to realize continuous protection on the extended piston rod of the oil cylinder. The device is convenient to use and obvious in effect, the hydraulic excavator oil cylinder canbe effectively protected through the device, the working safety is greatly improved, faults are reduced, and the repair and maintenance cost is reduced.
