[0039] The process of using the easy-to-carry circulating gas compressor impeller disassembly and assembly tool provided by this utility model is as follows: First, slide the impeller body 9 to be installed into the inner side of the arc-shaped support frame 8, so that the arc-shaped support frame 8 can support it. Then, start the first motor 13 to drive the worm gear 14 to rotate. The meshing of the worm gear 14 and the worm wheel 12 drives the first screw barrel 11 to rotate, which in turn drives the lifting inner frame 10 to move down through the guidance of the first guide column 7, so that the two semi-circular hollow positioning plates 17 move to both ends of the arc-shaped support frame 8. At this time, start the second motor 22 to drive the second flat plate... When gear 23 rotates, the meshing between the second spur gear 23 and the first spur gear 21, as well as the meshing between every two first spur gears 21, drives the two second screw cylinders 20 to rotate synchronously. In conjunction with the threaded connection between the second screw cylinder 20 and the second screw 18, and the sliding guidance between the second guide post 19 and the lifting inner frame 10, the first end frame 15 and the second end frame 16 move closer to each other, so that the two semi-circular hollow positioning discs 17 slide into the inner side of the arc-shaped support frame 8, and press and seal the two ends of the impeller body 9, thus completing the fixation of the impeller body 9.

[0040] At this point, the tool frame 1 is easily hoisted and transported to the impeller installation location in the compressor using the lifting lug 3. Then, the height of the bearing top plate 4 is controlled by the hydraulic lifting mechanism 5 to align the impeller body 9 with the shaft of the compressor. The tool frame 1 is then pushed by the double-acting pulley 2 so that the shaft passes through the impeller body 9 to complete the installation of the impeller body 9. The first end frame 15 and the second end frame 16 are then moved away from each other so that the two semi-circular hollow positioning discs 17 move out from the inside of the arc-shaped support frame 8. The inner lifting frame 10 is then raised again to release the obstruction of the two semi-circular hollow positioning discs 17 at both ends of the impeller body 9, thus making it easier to push the tool frame 1 out from the outside of the shaft to complete the installation.

[0041] Similarly, when it is necessary to disassemble the impeller body 9 from the outside of the shaft, first hoist the tool frame 1 to the impeller installation location, and push the tool frame 1 to move it to the outside of the shaft, so that the impeller body 9 moves to the inside of the arc-shaped support frame 8. Then, control the two semi-circular hollow positioning discs 17 to press and seal the impeller body 9, so that the tool frame 1 can be pushed out from the outside of the shaft, and the disassembly of the impeller body 9 can be completed.
