Description

Technical Field

[0001] The utility model belongs to the technical field of fasteners, and in particular relates to a large torque adaptive torsion mechanism. Background Art

[0002] At present, there are many blowout preventer manufacturers in China, with many product specifications and models. BOP repair factories generally use pneumatic wrenches to disassemble and assemble the bolts of blowout preventers. Pneumatic wrenches mainly use air sources to push the impact hammer inside the wrench, causing the impact hammer to accelerate and hit the output shaft, and finally complete the action of disassembling bolts and nuts. At present, the blowout preventer bolt disassembly and assembly tools do not have a fixed reaction force arm as a fulcrum. The operator needs to use both hands to straighten the reaction force arm as the fulcrum, which poses certain safety hazards during operation. At the same time, there are differences in the design of the blowout preventer side door bolts by various manufacturers. There is interference in the front disassembly and assembly of some side door bolts.
