近年来,对井下设备组装、维修、拆卸用的手持动力工具,日益需要,促进了钻、锯、旋、拧、拆卸螺帽,切割线缆工具的开发。较早的研究表明,由于缺乏适用于驱动的电源,没有足够的空间条件等原因,它们潜在的效益未能充分发挥。此外,采用手持动力工具也造成了诸如咬住衣服,出现“反冲”、噪声、震动、发热、工具重、握举费力等问题。其它行业的实践表明,设计不良 In recent years, there is a growing need for hand-held power tools for the assembly, maintenance and disassembly of downhole equipment and the development of tools for drilling, sawing, screwing, disassembling nuts and cutting cables. Earlier studies have shown that their potential benefits have not been fully realized due to the lack of a suitable power source for driving and insufficient space conditions. In addition, the use of hand-held power tools also caused problems such as biting clothes, “recoil”, noise, vibration, heat, heavy tools and heavy lifting. Practice in other industries shows poor design
