The inner walls on both sides of the long box 6 are rotatably mounted with the same screw 11, and the screw 11 is a bidirectional screw. Two threaded blocks 12 are symmetrically screwed on the screw 11. By setting the screw 11, the two threaded blocks 12 can be driven to move closer to or away from each other. A support plate 13 is fixedly mounted on one side outer wall of the long box 6, and a motor 14 is fixedly mounted on the top outer wall of the support plate 13. The output end of the motor 14 passes through one side outer wall of the long box 6 and is fixedly connected to one end of the screw 11. The top outer walls of the two threaded blocks 12 are fixedly mounted with connecting blocks 15. By setting the connecting blocks 15, it can play a role of auxiliary installation, and an installation mechanism is provided between the connecting blocks 15 and the fixed column 4.

[0032] When in use, the two motors 14 are started synchronously, and the output end of the motor 14 will drive the screw 11 to rotate. The rotation of the screw 11 will drive the two threaded blocks 12 and the two connecting blocks 15 to approach each other. The two connecting blocks 15 approach each other, which will drive the two fixing columns 4 and the two supporting wheels 5 to approach each other, thereby completing the installation and detection of impeller shafts with different diameters.

[0033] Reference Figure 3 The installation mechanism includes a connecting column 17, a connecting hole 16 is formed on one side of the outer wall of the connecting block 15, the connecting column 17 is slidably installed in the connecting hole 16, a thread 18 is formed on one side of the outer surface of the connecting column 17, and a nut 19 is screwed on the thread 18. By rotating the nut 19 and removing the nut 19, the connecting column 17 can also be removed at this time, and then the support wheel 5 can be disassembled and replaced.

[0034] Reference Figure 3 The nut 19 is located on one side outer wall of the connecting block 15 and contacts therewith. By arranging the nut 19 to be located on one side outer wall of the connecting block 15 and contact therewith, it is convenient to limit the position.

The output ends of the two cylinders 10 are fixedly mounted on the outer wall of one side of the long plate 2. By starting the two cylinders 10 on both sides, the output ends of the two cylinders 10 will push the two long plates 2 and the two supporting wheels 5 to approach each other, thereby supporting impeller shafts of different lengths.

[0040] The implementation principle of the present application is as follows: when in use, the impeller shaft is supported between the four support wheels 5 on both sides, and the impeller shaft is rotated manually. When the impeller shaft stops rotating, there is a possibility that the impeller shaft is bent on the side close to the ground, so that the test can be completed. By controlling and starting the two motors 14, the output end of the motor 14 will drive the screw 11 to rotate, and the rotation of the screw 11 will drive the two threaded blocks 12 and the two connecting blocks 15 to approach each other. The two connecting blocks 15 approach each other, thereby driving the two fixing columns 4 and the two support wheels 5 to approach each other, so that the installation test of the impeller shafts with different diameters can be completed;

[0041] By starting the two cylinders 10 on both sides, the output ends of the two cylinders 10 will push the two long plates 2 and the two supporting wheels 5 to move closer to each other, thereby supporting impeller shafts of different lengths;

[0042] When the support wheel 5 needs to be disassembled and replaced, the nut 19 is rotated and removed, and the connecting column 17 can also be removed at this time, thereby completing the disassembly and replacement of the support wheel 5.
