一种大包事故回转手动逻辑控制液压系统

A Manual Logic Control Hydraulic System of Ladle Accident Returning

以安全、可靠、操作方便为主题,依照业主要求,对现有大包事故回转控制回路进行重新设计,用手动事故回转代替原有的电磁阀事故回转,手动事故回转简单明了易操作,电磁阀事故回转需要若干只电磁铁协同通、断电才能实现回转,一旦电磁铁或电气故障,电磁阀事故回转失效只能等待对原理非常熟悉的专业人员手动事故回转,操作复杂且易出错,且易酿成安全事故。重新设计的手动事故回路不仅能方便的实现回转(仅需扳动操作手柄即可)而且只允许沿事故溜槽单方向(安全方向)回转,如果慌乱中操作手柄扳错方向,原理设计能确保大包静止不动,重新操作手柄大包沿事故溜槽方向回转。简单、安全、可靠,完全满足业主要求(已获专利,专利号:ZL 2015 2 0663557.3)。

With safety、reliable、convenience to operate as the theme,according to the demand of owner,redesign existing ladle accident returning circuit,use manual accident returning instead of original solenoid valve accident returning,the former is simple and easy to operate,the later needs several solenoid valves cooperate with each other to complete the function.Once solenoid or electric fault,the function of solenoid valve accident returning invalid,we can only wait professionals that very familiar to the principle to handle the problem.It is complicatedto operate and easy to make mistake and cause safety accident.The redesign manual accident returning circuit not only convenience toreturning(need only Throw the handle)but also allow returning single-way along accident chute(safety direction),If the handle is operatedin panic in the wrong direction,principle ensure the ladle motionless,operating the ladle again returning along accident chute.Simple,safety,reliable.Fully meet the requirements of the owner.
