Summary : In recent years, as China's sustained rapid economic development, China's oil consumption will increase every year. 2002 reached million tons, ranking over Japan as the second largest after the United States following the oil-consuming countries Le. In contrast, our oil production growth has been relatively slow mechanical, supply and demand have e increasingly conspicuous. Over the past 10 years, China's domestic production growth momentum tongs, but as abroad, my motivation tongs plex, cumbersome to use and maintain, such as the use of the short duration of ings, the vigorous development of China's power tongs are designed to transform and reach the world level.
Keyword :-pole power tongs, hydraulic motors, hydraulic transmission

现在,我国动力钳大体分开口、闭口钳两种,各有优缺点。主要工作原理是压力源将压力通过输油胶管输入马达,马达主轴转动,经过齿轮系使钳头开口大齿轮转动,同时联接主背钳的输油胶管,将压力输送到背钳油缸,推动运动,经过齿轮副带动颚板相对背钳头主体上的坡板转动一定角度,使颚板总成上的牙板夹紧油管,同时主钳的钳头开口大齿轮转动时,颚板架在制动摩擦力作用下,先不转动,迫使颚板上的滚子沿坡板爬坡,推动颚板及牙板径向移动直至咬紧油管,然后随开口大齿轮转动,实现旋紧或旋开油管螺纹的目的。
但动力钳要可更换板牙,夹持不同规格的抽油管,结构简单、方便拆卸、调整维修方便,制动安全,可靠耐用。这就需要其结构不断的改进与发展。
、分析问题
通过毕业设计对液压控制系统进行设计与解析,并通过实践掌握液压传动原理及背钳工作原理。对背钳整体结构进行优化,达到背钳简洁实用。通过高压输油胶管与主钳连接,使主钳背钳均由一个手
