摘 要:在能源，交通，冶金，化工，矿山及其他行业的设备安装，检修工作中，装拆大规格螺栓比较困难；有些螺栓安装在空间非常窄小的地方无法用加长力臂或用锤击的方法紧固和拆卸螺栓；由于设备的长期使用和工作环境的恶劣，在高温而又潮湿的地方，螺栓将受到严重的锈蚀，用人工无法拆卸锈蚀螺栓，所以难以检修；在架空管道和高空设备构架上紧固和拆卸螺栓，工作人员虽然戴着安全带也难以用上力，要安全地完成工作非常困难；据设备管理权威机构统计，在设备运行故障中有50%以上是因为螺栓问题引起的，因螺栓问题而造成设备重大事故的数量也非常惊人，因此新的设备安装和检修规范对螺栓紧固的力矩要求比较严格，而用人工方法难以达到要求。 37008

Abstract：In the energy, the transportation, the metallurgy, the chemical industry, the mine and other professions equipment setups, in the overhaul work, the assembling and dismantling big specification bolt quite is difficult; Some bolts install in the spatial extremely small and narrow place are unable with to lengthen the arm of force or with the method fastening and the disassemblage bolt which hammers; Some equipment long-term use in the quite moist place, the bolt rusts away seriously is unable with the artificial disassemblage, thus overhauls with difficulty; In elevated duct and on high altitude equipment skeleton fastening and disassemblage bolt, staff although wears the safety belt also with difficulty to use the strength, must safely complete the work to be extremely difficult; According to the equipment management authoritative organization statistics, has above 50% in the equipment movement breakdown is because the bolt question causes, but creates the equipment significant accident because of the bolt question the quantity also extremely astonishing, therefore the new equipment setup and the overhaul standard fasten to the bolt the moment of force request quite is strict, but meets the requirements with difficulty with the artificial method.
Above the hydraulic pressure torque spanner solves the question ideal tool. This tool the high-pressure oil which produces with the necessary ultrahigh voltage hydraulic pump takes the power, automatically completes the bolt the fastening and the disassemblage work, steady, does not have the impact, safe, the assembly quality is high
