凿岩机

The simulation studies of two commerical impact machines, namely, YYG90 hydraulic rock drill and D12 diesel pile hammer, are performed.

应用微机模拟软件，对两类典型的冲击机械，YYG90液压凿岩机和D12柴油打桩锤，进行了模拟研究，为同类机械的选用和设计提供了理论依据。

Through the shallow hardening treatment,the steel T8A can have better contact-fatigue resistance to the repeatedimpactload-test and can be used for making the piston of rock drill.

经薄层硬化的T8A钢，可以获得较好的多冲接触疲劳抗力，故有可能作为凿岩机活塞用材。

Combining traditional DTH hammer with pneumatic rock drill,by reference to the rotational mechanism of rock drill,studies the rotational mechanism of DTH hammer and introduces a new type of DTH hammer that uses backstroke energy of piston to drive drill to rotate.

将传统的潜孔锤与凿岩机相结合，研究了潜孔锤孔底回转机构，介绍了一种新型的潜孔锤。

The rock-melting drill is of a shape and is propelled under sufficient pressure to produce and extend cracks in solid rock radially around the bore by means of hydrostatic pressure developed in the molten rock ahead of the advancing rock drill penetrator.

这种岩熔钻孔机具有着一种形状，它在足够的压力下才能推进，从而在坚硬的岩石中产生裂缝并使其在钻孔周围成放射状地扩展延伸，它是凭借液体静压力的方式推进的，而这种静压力产生于正前进的凿岩机弹头前方的熔融岩石。

Domestic industries with the highest quality awards; 1995, the company's products are rock-drilling machines as the first batch of brand-name products in Jiangxi Province.
