[0002] The cylinder bolts of the reactors in petrochemical enterprises are characterized by large number, multiple specifications, heavy weight, and multiple fastening methods, which makes the maintenance of the reactors difficult and risky. At the beginning and end of the maintenance, the disassembly and assembly of the cylinder connection bolts is time-consuming and laborious. In addition, the installation height of such equipment is usually high, resulting in a high installation position of the cylinder bolts and a small space. During the bolt installation operation, it is necessary to operate on a frame platform or scaffolding. When disassembling and assembling screws and nuts, due to the different installation heights of the equipment screws and the tight fit of the cylinder bolt threads of the reactor, these characteristics require the installers to adjust the appropriate installation position and maintain the operating posture for a long time during the operation. The small space causes the operators to rely on their feelings to judge whether the bolts are installed in place. When disassembling and assembling screws and nuts, they need to be disassembled and assembled one by one by the operators (electric or hydraulic tools are used to tighten them after manual tightening during installation). When relying on manual labor to lift and rotate the heavy screws and 3 kg nuts for disassembly and assembly, there is a risk of falling and injuring people, and the installation time is long and the efficiency is low.
