潜孔钻机的液压系统设计 说明书.docVIP

摘要 潜孔钻机的冲击器装于钻杆的前端，潜入孔底，随钻孔的延而不断推进，即因冲击器潜入孔底而得名。潜孔钻机不像凿岩机接杆钻进那样，能量损失随钎杆的加长而增加，因而能打深孔、大孔。应用于井下钻孔时，同凿岩机相比，由于冲击器深入孔内作业，工作面噪音大大降低。应用于露天钻孔时，同钢绳冲击式钻机相比，钻孔速度提高2-3倍，机械化程度较高，辅助作业时间少，提高了钻机作业率。 潜孔钻机的液压系统按其功能可分为四大部分，即推进回转液压控制回路，接卸钻杆液压控制回路，钻机的定位液压回路和行走调平液压控制回路。本次设计着重在于推进回转和接卸钻杆液压系统，兼顾定位和行走调平回路。 查阅相关资料，读懂并改进钻机液压系统，此系统设计环境要求占用空间越小越好，流量不能过大，因此可以采用开式油路。虽是野外作业但可接入电源，采用异步电动机驱动。根据系统参数，计算后查阅样本选择合适元件，设计油箱、集成阀块和泵站，通过计算验算系统性能是否满足要求。 关键词　潜孔钻机 液压系统 多路阀 集成阀块 泵站 Abstract The impactor of submersible drilling rig installed in the the ens of the drill ,sneaking into the bottom of the hole.That is the origin of its name. Submersible drilling rig is different to drilling machine, which uses the unloading pipe,so energy loss increases with the lengthened of drill.Thus the submersible drilling rig can dig deep and large hole .Used in well drilling, noise reduces greatly compared to drilling machine ,becausse its impactor deep hole operations. Used in open-air drilling, its digging speed improves two or three times compared to the same rope impact drill.the degree of Mechanize increases,Auxiliary operation time decreases,improve the efficiency. According to their function,Submersible drilling rig hydraulic system can be divided into four parts , we can tell them promoting and rotary hydraulic control circuit, the loading and unloading dril hydraulic control circuit ,submersible drilling position hydraulic circuit and walking hydraulic circuit .My design emphasis on promoting and rotary hydraulic control circuit and its loading and unloading dril hydraulic control circuit ,taking into account the location and walking hydraulic circuit. Referring to relative information, reading and improving the submersible drilling rig hydraulic system.This system environment requires footprint as small as possible, the flow is not too large, so I choose to use the open circuit. Although it works outside but we can get AC , so I use asynchronous motor. Depending on the system parameters,select the appropriate
