[0002] In the production of petrochemical industry, compressors are needed for gas transportation and pressurization in the production process, among which screw compressors are the most widely used. Since the medium conveyed by screw compressors is relatively complex, the failure rate of the unit is relatively high, which makes the frequency of screw compressor maintenance high. In the process of screw compressor maintenance, it is often necessary to extract the rotor and inspect the rotor. In order to avoid the rotor from rubbing and causing rotor wear during the extraction process, the casing of the screw compressor needs to be turned over, and then the rotor is extracted horizontally using mechanical equipment.

[0003] Traditional screw compressor maintenance requires the use of a bridge crane or a crane with a manual hoist to flip the screw compressor casing, which not only increases the maintenance cost but also prolongs the maintenance time. Utility Model Content

[0023] Working principle:

[0024] like Figure 1-3 As shown, when the auxiliary tooling is in use, the casing 18 of the screw compressor is placed on the two receiving rods 5. First, according to the size of the casing 18 of the screw compressor, the width between the two bottom rods 1 can be adjusted by adjusting the connection between the bolts 10 and the connecting nuts 14. After the adjustment of the bottom rods 1 is completed, the screw holes on the back of the casing 18 are aligned with the long grooves 11 of the receiving rods 5, and then the fixing bolts 19 are used to pass through the long grooves 11 and connect with the screw holes on the back of the casing 18, so that the casing 18 can be fixed on the receiving rod 5, and then the hydraulic cylinder 6 is started, and the receiving rod 5 is pushed to rotate around the second support rod 3 through the output end of the hydraulic cylinder 6, so that the casing 18 is turned over, and the extraction direction of the rotor 20 in the casing 18 is parallel to the horizontal direction. , and then the telescopic rod 8 is driven to rotate by rotating the rotating nut 15, so that the external thread of the telescopic rod 8 rotates on the internal thread of the supporting tube 4, thereby adjusting the extension length of the telescopic rod 8, so that the top of the load-bearing plate 7 contacts the shell 18, and the load-bearing plate 7 bears the shell 18 to prevent the shell 18 from sliding down along the receiving rod 5 under the action of gravity. Finally, by rotating the horizontal adjustment bolt 9, the tail end of the horizontal adjustment bolt 9 can lift the bottom rod 1, thereby adjusting the parallelism of the bottom rod 1 with the horizontal line, and then fine-tuning the extraction direction of the rotor 20 to improve the extraction accuracy of the rotor 20.
