Mining electric shovel working device for electrohydraulic auxiliary operation motion
The invention provides a mining electric shovel working device for electrohydraulic auxiliary operation motion, which belongs to the technical field of mining engineering machinery and aims to solve the problems that energy loss of an existing electric shovel working device is severe, and a lifting force utilization rate of a lifting steel wire rope is low. The mining electric shovel working device is mounted on an electric shovel body with a winding device, and is characterized by comprising a movable arm, a shovel loader, a bucket rod hydraulic rod and an auxiliary hydraulic cylinder. According to the design in the invention, an auxiliary hydraulic cylinder is additionally arranged to assist the bucket rod to lift, so that a steel wire rope stress condition is improved while the bucket rod is too high or too low, lifting force moment and digging force of the bucket rod hydraulic cylinder are improved; the auxiliary hydraulic cylinder can be used for recycling gravitational potentialenergy of the working device, so that energy waste is reduced; and the hydraulic cylinder is taken as a power source to control the bucket rod to extend out and draw back, so that push force of a pushmechanism is increased, and operation stability of the mechanism is improved.
本发明提供了一种电液辅助作业运动矿用电铲工作装置，属于矿用工程机械技术领域，旨在解决现有电铲工作装置能量损耗严重，提升钢丝绳提升力利用率低的问题；安装在带有卷扬装置的电铲车身上，其特征在于，包括动臂、铲斗、斗杆液压缸和辅助液压缸；本发明中的设计，增设辅助液压缸辅助斗杆抬升，在铲斗过高或过低时，改善钢丝绳受力情况，提高了斗杆液压缸的提升力矩和挖掘力；辅助液压缸可以用于回收工作装置重力势能，减少了能量浪费；采用液压缸作为动力源控制斗杆伸缩，增加了推压机构推力，并改善了机构的作业平稳性。
