摘　　要：设计了一种微型纯电动遥控轮式液压抓斗挖掘机模型,初步设计了纯电动遥控挖掘机电液控制系统的总体结构、液压系统及遥控控制系统。挖掘机的硬件结构部分采用铝合金材料制作,整体比例缩小,能应用于5 kg以内小型物体的抓取。液压系统采用电磁阀对工作装置进行控制。遥控器及车载控制单元均采用51单片机开发,遥控频率采用2.4 GHz,实现500 M以内距离控制。同时,系统具有轻量化、行走快速、实用、新颖等特点。A miniature electric remote-control wheel type hydraulic grab excavator model is designed in this paper. The overall structure, hydraulic system and remote-control system of the pure electric remote-control excavator are preliminarily designed. The hardware structure of the excavator is made of aluminum alloy, overall proportionately reduced. It can be used to capture objects within 5 kg. The hydraulic system uses the solenoid valve to control the working device. The remote control and the vehicle control unit are all developed by 51 single chip microcomputer. The remote-control frequency is 2.4 GHz, and the remote control within 500 M is realized. At the same time, the system has the characteristics of light weight, fast walking, being practical and novel and so on.
