煤层气车载钻机多功能液压卸扣器的研制
|
摘要
针对目前煤层气(Coal Bed Methane,CBM)车载钻机施工现场所用卸扣器使用过程中出现的重量大、扭矩小、适用范围窄、使用步骤繁琐等问题,研制了一套多功能液压卸扣器,最大卸扣扭矩130 kNm,满足Φ73～400 mm钻杆、钻头、潜孔锤等钻具联接丝扣的卸扣需求,同时解决现有煤层气车载钻机在发生事故时,动力头与钻杆上部丝扣卸扣困难的问题。工业性试验表明该卸扣器卸扣能力强、结构轻便、适用钻具范围广,操作简便,提高了钻具卸扣效率,降低了工人劳动强度。
Aiming at the problems of heavy weight,small torque,narrow scope of application and cumbersome use steps on the break-out device used in the construction site of truck-mounted CBM drilling rig at present,a set of multifunctional break-out device has been developed. The maximum torque of the break-out device is 130 kN·m,it can meet the requirements of breaking out of Φ73～400 mm drill pipe,drill bit,down-the-hole hammer and other drilling tools. At the same time,it solves the problem that the power unit and the upper thread of drill pipe are difficult to be broke out in the event of an accident on the existing truck-mounted CBM drilling rig. The industrial test shows that the device has strong break-out ability,light structure,wide application range of drilling tools,simple operation,the efficiency of break-out is improved and the labor intensity of workers is reduced.
