摘要
矿用液压起吊设备是用于井下大型采煤设备搬运的关键性设备,设计了一种矿用液压支架起吊机,重点研究设计了起吊液压控制系统。应用AMESim对整个液压系统进行分析,得到了系统流量响应特性曲线,应用Pumplinx对关键性液压控制元件进行了流场分析,得出了压力分布图、速度分布图以及空化分布,为整个液压起吊机的可靠性设计提供了依据。通过现场应用,在起吊支架重载设备过程中,起吊机运行可靠,能够保证立柱负载能力和速度及位置同步要求,大大加快了工作面搬家速度。
Mining hydraulic hoisting equipment is a key equipment for large-scale coal mining equipment handling in underground mines. Designs a mining hydraulic lifting machine for cranes and focuses on designing a lifting hydraulic control system. AMESim was used to analyze the entire hydraulic system, and the system flow response characteristic curve was obtained. Pumplinx was used to analyze the flow field of critical hydraulic control elements, and pressure distribution maps, velocity distribution maps, and cavitation distributions were obtained for the entire hydraulic lifting. The reliability design of the machine provides the basis. Through on-site application, in the process of lifting the heavy-duty support equipment,the crane is reliable in operation, and can guarantee the column load capacity and speed and position synchronization requirements, greatly speeding up the moving speed of the working surface.
