Example Sentences:

	1.	Study on the reform plan of main hoist skip in hiang jia coal mine 梁家煤矿主提升箕斗改造方案研究
	2.	Main hoisting equipment for drilling rig 石油钻机主要提升设备
	3.	This drilling adopts crank connecting link and walking beam percussion mechanism , which make the drilling possess two percussive functions , normal drilling takes connecting link impact as main mode , when encountering special situation and the connecting link impact can not drill , it can transform into hoisting impact , the stroke length can be modulated , it realizes automatic percussive drilling due to continuous operating of connecting link percussive mechanism , these can enhance drilling efficiency and relieve labor intensity ; it adopts pumping reverse circulation to drain slag , which not only resolves the drilling difficulty in special stratum such as pebble and gravel stratum and hard stratum , but also resolves the problem that the percussive drill ' s efficiency is low ; it adopts spur gear differential mechanism as double cylinders lazy tongs of main hoist , which not only ensures the balance state of drilling tool , but also reduces the mechanical design , and reduces the cost ; the bottom plate traveling motion of this drilling machine adopts walking type ; the drilling tower adopts hydraulic pressure uprising , and reduces the assistant operating time 该钻机采用曲柄连杆、游梁式冲击机构，使钻机具有两种冲击功能;正常钻进以连杆冲击为主，遇到特殊情况，用连杆冲击不能钻进时，可转为卷扬冲击，冲程可调，因连杆冲击机构连续工作，所以实现了自动冲击钻进，可提高钻进效率，减轻劳动强度;采用泵吸反循环的方式排渣，既能有效解决卵砾石地层、坚硬地层等特殊地层钻进的困难，又很好地解决了冲击钻机效率低下的问题;采用直齿圆柱齿轮差速机构作为主卷扬的双筒同步机构，既保证了钻具处于平衡状态，又大大简化了该机构设计，降低了成本;该钻机底盘行走移位采用步履式;钻塔采用液压起立，减少了辅助作业时间。
