选煤厂电动环链提升机智能控制研发与应用

Development and application of electric chain hoist in coal preparation plant

基于老旧厂房设备布置紧凑,空间位置有限,且电动环链提升机一般由操作手柄、控制线组成,远距离运输过程中极易损坏电源线及控制手柄,一旦发生链条断裂、钩头掉落、主机失控等故障后,人员无安全躲避空间,造成人身伤害等问题,基于“无人则安,安全高效”理念进行智能化改造,针对目前存在的问题提出具体改造措施,并对改造创新点和改造效果进行分析。将传统操作手柄改造为远距离遥控操作,同时增加微电机综合保护,实现电动环链提升机操作安全便捷,起到防止超重、歪拉斜拽等不安全行为,实现安全、高效作业。

Based on the compact layout and limited spatial location of old factory equipment,and the fact that electric chain hoists are generally composed of operating handles and control lines,power lines and control handles are easily damaged during long-distance transportation.Once faults such as chain breakage,hook head falling,and host loss of control occur,personnel have no safe escape space,causing personal injury and other problems.Based on the concept of"no one is safe,safe and efficient",intelligent transformation was carried out.Specific transformation measures were proposed for the current problems,and the innovation points and transformation effects were analyzed.Transforming the traditional operating handle into remote control,while adding comprehensive protection for micro motors,to achieve safe and convenient operation of the electric chain hoist,preventing unsafe behaviors such as overweight,tilting,and pulling,and achieving safe and efficient operation.
