The tightening assembly comprises a first cross rod, a long rod, a driving unit and a balance weight unit. One end of the long rod is connected with the hanging head, the other end of the long rod is fixed to the first cross rod, the driving unit and the balance weight unit are arranged at the two ends of the first cross rod correspondingly, and the driving unit comprises an operation head and a driving motor driving the operation head to rotate. According to the long rod type automatic fastening device, bolts in deep water can be simply and safely fixed.

Description

technical field [0001] The invention belongs to the technical field of nuclear power operation and maintenance, and in particular relates to a long rod type automatic fastening tool. Background technique [0002] Nuclear facilities used for nuclear power generation require regular maintenance and inspections. Many of the equipment with relatively high radioactivity are fixed at the bottom of the pool. The installation and disassembly of these equipment needs to be completed in a deep pool. In particular, bolt fastening operations in various complex environments and limited space locations are very difficult to implement on site. [0003] At present, long rods are mostly used for underwater fastening of equipment screws in nuclear power plants, and bolts matching the equipment are installed at the front end of the long rods, and the underwater camera is used to complete the installation and removal of fasteners. This method is difficult to operate, and it only operates on th...
