This topic research is entire hydraulic pressure opens the iron gate machine hydraulic system design, The control system uses hydraulic control flexibility, rapid advantages, as soon as changed formerly the manual control commutation for the hydraulic system recognition automatic control commutation. The Taphole driller from the beginning of the end of the work to return to the work space for parking, adopted hydraulic automatic control, does not need the manual intervention, enhanced has opened the hole 如有你有帮助，请购买下载，谢谢！ ability and opens the hole speed, adapted the modernized large-scale blast furnace request. This system mainly of the impact, the extension rock drill, advances and rotates four part of hydraulic control system composition, The design of the topics issues of this part of the four hydraulic systems, And the total hydraulic system, the composition and properties of checking system, It also explains the parts of the design process and calculating the necessary strength check.
