Problems solved by technology
Although this method does not need to disassemble the rotating parts, 6 to 7 operators are required, but the use conditions are limited, that is, the hanging point of the chain hoist must correspond to the radial centerline of the supporting tile, and it is required to operate two chain hoists. The personnel must cooperate perfectly, otherwise the tova will bump into the mirror plate of the thrust bearing, causing damage to the mirror surface

The invention relates to a thrust bearing shoe dismounting-and-mounting installation and a dismounting and mounting method thereof. The thrust bearing shoe dismounting and mounting installation comprises a supporting framework and a trolley; the supporting framework comprises a supporting surface, a plurality of height-adjustable supporting legs and a positioning part; the supporting surface is arranged on the top ends of the supporting legs, and is supported by the supporting legs; the positioning part is arranged on one side of the supporting surface, and is used for stabilizing the position of the supporting framework; two guide rails and a locking mechanism are arranged on the supporting surface, the locking mechanism is connected with the two guide rails, the trolley can slide along the guide rails, and the locking mechanism is used for locking the position of the trolley on the supporting framework. The thrust bearing shoe dismounting and mounting installation and the dismounting and mounting method thereof have the advantages of time and labor saving and low cost.
Description
technical field [0001] The invention relates to a special tool for maintenance, in particular to a thrust bearing bracket disassembly device and a disassembly method thereof. Background technique [0002] The thrust bearing is an important part of the generator set, which bears the weight of the rotor of the generator set and the axial water thrust. Such as figure 1 As shown, the thrust bearing includes a supporting shoe 11 and an elastic oil tank 12, and the supporting shoe 11 is supported on the elastic oil tank 12, and usually includes 12 supporting shoes 11 in a circle, each of which is composed of A set of the elastic oil tank 12 is supported. [0003] A prior art thrust bearing bracket disassembly method is to use the bridge crane of the factory building to directly hoist out and reassemble the brackets one by one after removing the parts of the rotating part of the generator during A-level maintenance. The disadvantage of this method is that it is necessary to use ...
