针对超静定液压支架在升架过程中多缸同步的需求,基于液压阀同步的方式,采用插装阀对超静定液压支架的液压系统进行设计,并分析了其工作原理和性能。结论表明:采用插装阀的液压支架液压系统具有工作可靠性高、抗污染能力强、便于维护,能实现支架的快速移架,满足某些特殊工况的需求,具有很高的应用价值。
Aiming at the need of multi-cylinder synchronization during the process of hoisting the statically indeterminate hydraulic support, the hydraulic system of the statically indeterminate hydraulic support was designed by the cartridge valve based on the way of hydraulic valve synchronization. The working principle and performance of the hydraulic system were analyzed. The conclusion shows that the hydraulic support hydraulic system with cartridge valve has the advantages of high work reliability, strong anti-pollution ability, easy maintenance, fast moving frame to meet the needs of some special working conditions and high application value.
