AI Technical Summary

Technical Problem

When operating machinery is turned around with its tracks not extended or not fully extended, it is prone to tipping over, leading to safety accidents.

Method used

By comparing the actual stroke of the hydraulic cylinder piston rod with the safe stroke, and combining this with the comparison of the actual rotation angle of the upper vehicle with the safe rotation angle, the rotation brake is controlled to ensure that the rotation brake is released when the actual stroke of the hydraulic cylinder piston rod is greater than or equal to the safe stroke or the actual rotation angle of the upper vehicle is less than or equal to the safe rotation angle, thus achieving 360° safe rotation.

Benefits of technology

This effectively prevents overturning accidents of operating machinery during the slewing process and improves the safety of slewing.

Abstract

本发明涉及作业机械技术领域,提供一种防侧翻回转控制方法、液压控制系统及作业机械。防侧翻回转控制方法包括:检测液压缸活塞杆实际行程,并将所述液压缸活塞杆实际行程与液压缸活塞杆安全行程进行比较;在所述液压缸活塞杆实际行程大于等于所述液压缸活塞杆安全行程的情况下,解除回转制动,否则检测上车实际回转角度,并将所述上车实际回转角度与所述液压缸活塞杆实际行程所对应的上车安全回转角度进行比较;在所述上车实际回转角度小于等于所述液压缸活塞杆实际行程所对应的上车安全回转角度的情况下,解除回转制动。由此,能够避免作业机械在上车回转过程中发生侧翻等危险事故,极大提升了作业机械上车回转的安全性。
