摘要
针对现有的装载机动臂手动矫正装置液压系统存在操作繁琐、只能手动及控制精度低等问题,在分析现有装载机动臂矫正装置工作原理的基础上,提出了采用双向电磁组合阀、保压阀、压力传感器、IO卡控制油缸开关等技术的新型动臂智能矫正液压系统方案。介绍了该系统的智能工作原理及特点、主要液压元件的选型,分析了系统运行过程。该系统用于装载机动臂焊后变形的矫正,具有智能操作、保压、系统结构简单、维护方便、控制能力强及精度高等特点。
The loader arm manual correction device of the hydraulic system are complicated operation,only manual operation and low control precision,based on the analysis of the existing loader boom correction device principle,proposed a bidirectional electromagnetic combination valve,pressure retaining valve,pressure sensor,IO card control cylinder switch technology model boom intelligent correction hydraulic system. This paper introduces the principle and characteristics of the system,the selection of the main hydraulic components,and analyzes the operation process of the system. The system is used to correct the deformation of the flexible arm after loading, which has the characteristics of intelligent operation, maintaining pressure, simple structure, easy maintenance,high control ability and high precision.
