针对现有钻机操作复杂,工人劳动强度大的问题,通过对比整体式钻杆箱与回转式钻杆箱的优缺点,研制出分体抓取式钻杆箱。抓取钻杆机械手及分体抓取式钻杆箱可以将钻杆箱内水平放置的钻杆抓出,送到主机对应的位置,完成自动上钻,亦可将主机拆卸下的钻杆放回钻杆箱。以自动控制钻机为例,阐述了该钻杆箱的结构及研制过程。通过实验室及现场试验验证,结果表明,该钻杆箱自动化程度高,性能可靠,可满足自动钻机自动装卸钻杆的要求,可为同类钻机的研制提供依据和参考。
In view of the complicated operation of existing rigs and the labor intensity of workers, a split grab-type drill rod box was developed by comparing the advantages and disadvantages of integral and rotary drill rods. Grasping drill pipe manipulator and split grab-type drill rod box can be placed horizontally drill pipe drill rod out, sent to the host corresponding location to complete the automatic drilling, the host can also be removed under the drill pipe Back to drill rod box. Taking the automatic control drilling machine as an example, the structure of the drill pipe box and its development process are expounded. Through laboratory and field test, the results show that the drill rod box has high degree of automation and reliable performance, which can meet the requirements of automatic drill rig for automatic loading and unloading drill pipe, which can provide the basis and reference for the research of similar drilling rig.
