Abstract

The invention discloses a tool and a method for disassembling an oil cooler of a thrust bearing of a water-turbine generator set. The tool comprises a connecting plate (1), cooler connecting pipes (2), a counterweight connecting pipe (3) and an adjustable counterweight device (4), wherein two cooler connecting pipes (2) are symmetrically welded on one side of the connecting plate (1), and the counterweight connecting pipe (3) is welded at the central position of the other side of the connecting plate (1); a first connecting flange plate (5) is welded at the end of the counterweight connecting pipe (3), and the end of the counterweight connecting pipe (3) is connected with the adjustable counterweight device (4) through the first connecting flange plate (5); a second connecting flange plate (6) is welded at the end of the cooler connecting pipe (2), and a lifting hook (7) is mounted on the second connecting flange plate (6). The position of a counterweight block can be adjusted, so that the device and the method can be suitable for disassembling various different embedded coolers, the manufacturing cost is effectively reduced, and the work efficiency is improved.

Description

technical field [0001] The invention relates to a disassembly tool and a disassembly method, in particular to a disassembly tool and a disassembly method for a thrust bearing oil cooler of a hydraulic generator set, belonging to the field of mechanical equipment. Background technique [0002] The types of thrust bearing embedded oil coolers used by different hydroelectric generator sets in hydropower plants are different. Due to the differences in the types of thrust oil coolers, their weights and diameters of connecting flanges are also different. In addition, , since most parts of the cooler are in the oil tank, the cooler must always be kept in a horizontal state when disassembling, installing and lifting the cooler during maintenance, so as to prevent the cooling pipe from colliding with other thrust bearing equipment due to imbalance. The cooler is damaged. Therefore, different types of coolers need to be equipped with special disassembly tools. On the one hand, the ma...
