Description

Technical Field

[0001] The utility model relates to the technical field of compressor rotor assembly, in particular to a compressor rotor assembly tool. Background Art

[0002] The two ends of the compressor rotor should be assembled with the compressor impeller respectively, and the two-stage impeller compression structure is formed. Since the two impellers are of different sizes and are irregular in shape. The usual assembly method is to assemble the compressor rotor with one of the impellers. When assembling, the impeller needs to be laid flat, and then the compressor rotor is lifted vertically, aligned with the shaft hole of the impeller for installation, and the compressor rotor and the impeller are locked manually; then the other impeller is assembled and connected with the compressor rotor in a similar manner, but the operation difficulty of assembling the second impeller is greater than that of the first impeller, which is time-consuming and laborious. After the assembly with the impeller is completed, the compressor rotor and impeller, which are in a vertical state due to the lifting, need to be laid flat to a horizontal state. At this time, the compressor rotor and the impeller structures at both ends have been assembled and connected together, and it is necessary to use additional lifting equipment or ropes to level the compressor rotor, and it is also necessary to find the center of gravity of the compressor rotor and the impeller to adjust the balance (the impellers at both ends of the compressor rotor are of different sizes, so the overall center of gravity is also difficult to level), which further increases the difficulty of such operation.

Since different compressor rotors 6 have different lengths and shoulder positions, a distance adjustment device 4 is designed to adjust the positions of the two movable support frames 2 on the fixed platform 1 to adapt to the different shoulder distances, so as to provide support and locking for compressor rotors 6 with different structures.

[0027] The fixed platform 1 includes two fixed support feet 11 and two guide rail beams 12.

[0032] The concave V-shaped groove 311 and the concave V-shaped groove 321 are respectively provided with wear-resistant rubber pads 33, which can not only reduce the friction between the compressor rotor and the locking structure 3, but also avoid the collision between the compressor rotor 6 and the locking structure 3, thereby firmly fixing the compressor rotor 6.
