Problems solved by technology
However, in the later use after installation, if the emergency diesel generator is damaged, for example, the internal coil of the generator is burned out due to wrong operation during the on-site commissioning process, the emergency diesel generator needs to be removed from the workshop for transportation. Return to factory for repair
However, since the factory building has been closed and other engineering items have been installed, the interior space of the factory building is very narrow, so it is impossible to use a large crane to directly lift the generator, and the weight of the emergency diesel generator reaches 31T. The lifting capacity of the installed bridge crane is only 3T, so there is no suitable lifting equipment and lifting points in the factory building to realize the dismantling, reverse transportation and reassembly of emergency diesel generators

Embodiment Construction
[0029] The technical solutions of the present invention will be further introduced below in conjunction with the accompanying drawings and embodiments.
[0030] combine figure 1 As shown, adopting the method of the present invention to carry out the concrete steps of dismantling, reversing and repacking the emergency diesel generator in the M310 reactor type nuclear power plant are:
[0031] Step S1, laying the transportation track. Two parallel transport tracks are laid in the plant, one end of which passes through the gate of the plant to the outside of the plant, and the other end passes through both sides of the emergency diesel generator and extends to the tail of the emergency diesel generator.
[0032] Preferably, in this embodiment, channel steel is selected as the transportation track, which can assist in guiding the direction of the moving transportation process and ensure the stability of the emergency diesel generator transportation in the later stage. At the sam...

The invention belongs to the technical field of nuclear power equipment installation, and particularly relates to a lifting and conveying method for a nuclear power station emergency diesel generatorset. In order to realize the re-disassembling, back-conveying and reassembling operation of the nuclear power station emergency diesel generator set after installation, the invention provides the lifting and conveying method for the nuclear power station emergency diesel generator set. The lifting and conveying method for the nuclear power station emergency diesel generator set concretely comprises the following steps of S1, paving a conveying rail; S2,installing base beams of a tank trolley and a conveying bracket; S3, installing a lifting tool; S4, lifting the emergency diesel generator setto the conveying bracket; S5, moving the emergency diesel generator set out to the outside of a factory building through the tank trolley along the conveying rail; and S6, reassembling the emergency diesel generator set. According to the method provided by the invention, the re-disassembling, back-conveying and reassembling operation of the nuclear power station emergency diesel generator set after installation can be smoothly accomplished, and the construction efficiency of disassembling and reassembling the emergency diesel generator set is ensured.
Description
technical field [0001] The invention belongs to the technical field of installation of nuclear power equipment, and in particular relates to a hoisting method for an emergency diesel generator in a nuclear power plant. Background technique [0002] In nuclear power plants, the emergency diesel generator equipment is used as the medium-voltage emergency AC power supply in the nuclear power plant, and supplies power for the 6KV AC emergency power distribution systems LHA and LHB with emergency plant equipment. When the external AC power supply of the power plant is completely lost, the emergency diesel generator equipment can meet the power requirements of the emergency plant equipment, so as to ensure the safe shutdown of the reactor and prevent the failure of the normal external power system to cause damage to important equipment. damage. [0003] During the first installation process, the emergency diesel generator is directly hoisted by a large crane to the unit base fixe...
