[0020] Working principle: During operation, first, push the moving support frame 2 to move through the handle 3. The moving support frame 2 drives the rotating shaft rod 5 to move through the four mounting seats 4. The rotating shaft rod 5 drives the moving wheel 6 to rotate. At the same time, the moving support frame 2 drives the screw compressor unit body 1 to move. After the screw compressor unit body 1 moves to the designated position, stop pushing the moving support frame 2. Then, drive the rotating disk 43 to rotate through the adjusting rod 44. The rotating disk 43 drives the threaded rod 41 to rotate. The threaded rod 41 drives the threaded sleeve 40 to move. The threaded sleeve 40 drives the positioning slider 45 to slide inside the positioning chute 46, which can ensure better stability when the threaded sleeve 40 moves. At the same time, the threaded sleeve 40 drives the driving rack 39 to move. The driving rack 39 drives the driving gear 38 to rotate. The driving gear 38 drives the driving shaft rod 34 to rotate. The driving shaft rod 34 drives the driving wheel 35 to rotate. The driving wheel 35 drives the driven wheel 37 to rotate through the transmission belt 36. The driven wheel 37 drives the transmission shaft rod 16 to rotate. The transmission shaft rod 16 drives the transmission gear 17 to rotate. The transmission gear 17 drives the transmission rack 18 to move. The transmission rack 18 drives the positioning sliding sleeve 26 to slide outside the positioning sliding rod 27. The positioning sliding sleeve 26 drives the positioning sliding bar 29 to slide inside the strip-shaped chute 30, which can ensure better stability when the transmission rack 18 moves. At the same time, the transmission rack 18 drives the movable block 19 to move. The movable block 19 drives the movable plate 21 to move through the movable rod 20. The four corner plates of the movable plate 21 slide outside the four positioning cross bars 31 respectively, which can ensure better stability when the movable plate 21 moves; At the same time, the movable plate 21 drives the connecting shaft 22 to move. The connecting shaft 22 drives the movable strip 23 to move. The movable strip 23 drives the movable frame 25 to move through the movable shaft 24. The movable frame 25 drives the support rod 11 to move. The support rod 11 drives the sliding block 13 to slide inside the sliding groove 14, which can ensure better stability when the support rod 11 moves. At the same time, the support rod 11 drives the positioning seat 12 to move. The tapered groove on the side of the positioning seat 12 away from the support rod 11 contacts the outside of the tapered positioning block 7. As the positioning seat 12 moves, the tapered positioning block 7 is pressed and positioned, so that the moving wheel 6 can be positioned. Then, stop rotating the adjusting disk. At this time, all four moving wheels 6 are positioned, so that the moving support frame 2 can be positioned, completing the positioning operation after the movement of the screw compressor unit body 1. In this way, during the use of the mobile screw compressor unit, it can be quickly and stably positioned after moving, improving its stability, thus ensuring that the screw compressor unit can work normally.
