YSZ-50型声频振动钻机动力头减振方案的改进

Improvement of Vibration-absorbing Scheme for Dynamic Head of YSZ-50 Audio Frequency Vibration Drilling Rig

针对YSZ-50型声频振动钻机动力头存在的减振问题,通过分析国内外声频动力头减振方案的特点,提出了一种三道复合减振方案:第一道采用竖向销轴中的金属橡胶减振垫减振方式,吸收掉振动器振动能量的绝大部分,该方式为主要减振手段;第二道采用侧向复合橡胶块减振方式,吸收掉振动器传递到箱体振动能量的绝大部分,第三道采用普通橡胶垫减振方式,吸收掉箱体传递到回转马达的振动能量。试验表明,三道复合减振方案可有效解决YSZ-50型钻机动力头的减振问题。

According to the vibration-absorbing problems in YSZ - 50 audio frequency vibration drilling rig, by the analysis on the characteristics of vibration-absorbing schemes for dynamic head of audio frequency both in China and abroad, 3 com- posite vibration-absorbing schemes were put forward ： （ 1 ） with metal rubber shock pad in vertical pin to absorb most part of vibration energy in vibrator, and this was the main vibration-absorbing means; （2） with side composite rubber block to ab- sorb most vibration energy from vibrator to the box ; （3） with traditional rubber pad to absorb vibration energy from the box back to the rotary motor. It was proved by tests that these composite vibration absorbing schemes can effectively absorb the vibration of dynamic head of YSZ - 50 drilling rig.
