Abstract

本发明公开了一种能监测驱动轴应力和避免乱链的安全刮耙机构，属于料场取料机装备的技术领域。本发明的创新之处就是在保留刮耙机构具有自动刮料基本功能的前提下，通过增设对驱动轴的受力监测部件来及时监测驱动轴的应力，进而准确判断和实时掌握驱动轴是否处于安全工作状态，大大提高驱动轴及刮耙机构的使用安全性；本发明还在张紧链轮所在端增设有能够使同步链条的张紧状态保持稳定的锁紧装置，能够有效避免因油缸泄油及瞬间失压等原因引起张紧链轮移位而造成链条松弛及紊乱的乱链现象发生，避免因乱链引发刮耙机构失效而造成刮耙机构无法正常工作，大大提高刮耙机构的有效性、可靠性和安全性；同时锁定位置还具有灵活可调、使用方便的优点。
