DETAILED DESCRIPTION

[0016] like Figure 1-6As shown: an engine maintenance cart, including a frame 1, the frame 1 is I-shaped and has moving wheels 2 rotatably connected to the four ends, a push handle 3 is fixedly connected to the front side wall of the frame 1, a base 4 is fixedly connected to the middle of the front side wall of the frame 1, and guide rods 5 are vertically fixedly connected to the left and right sides of the top of the base 4, a top plate 6 is fixedly connected between the top ends of the two guide rods 5, a screw rod 7 is rotatably connected between the bottom center of the top plate 6 and the top center of the base 4, a bevel gear 8 is fixedly sleeved on the outer wall of the bottom end of the screw rod 7, a fixed seat 9 is fixedly connected to the top rear side of the base 4, a rotating shaft 10 penetrates the top of the fixed seat 9, the top of the fixed seat 9 is rotatably connected to the rotating shaft 10, and the rear end of the rotating shaft 10 is fixed It is connected with bevel gear 2 11, which meshes with bevel gear 1 8. The front end of rotating shaft 10 is fixedly connected with turning handle 12. Two guide rods 5 respectively pass through the two ends of moving seat 13. The two guide rods 5 are slidably sleeved with moving seat 13. Screw rod 7 passes through the middle of moving seat 13. Moving seat 13 and screw rod 7 are threadedly matched. The middle part of the rear side wall of moving seat 13 is fixedly connected with support shaft 14. The rear end of support shaft 14 is rotatably connected with gear 15. The front side wall of gear 15 is threadedly connected with four connecting bolts 16. The connecting bolts 16 pass through gear 15 and the rear end is threadedly connected with operating panel 17. The outer wall of operating panel 17 is provided with four mounting holes 18 distributed in X shape.

[0017] The right end of the movable seat 13 is rotatably connected to a rotating shaft 2 19, the rear end of the rotating shaft 2 19 is fixedly connected to a gear 20, the gear 20 is meshed with the gear 1 15, the front end of the rotating shaft 2 19 is fixedly connected to a turning handle 21, the top of the movable seat 13 is threadedly connected to a locking bolt 22, and the bottom end of the locking bolt 22 is tightly pressed against the outer wall of the rotating shaft 2 19.

[0018] First, the staff fixes the engine to be repaired on the operating panel 17 through the mounting holes 18 on the operating panel 17. The mounting holes 18 are distributed in an X shape to facilitate adapting to engines of different sizes and shapes.

[0019] The staff drives the rotating shaft 10 and the bevel gear 2 11 connected thereto to rotate by turning the turning handle 12. The bevel gear 2 11 meshes with the bevel gear 18, so the bevel gear 18 also rotates. The rotation of the bevel gear 8 drives the screw rod 7 to rotate. Since the screw rod 7 is threadedly matched with the moving seat 13, the moving seat 13 will slide up and down along the guide rod 5. The movement of the moving seat 13 will drive the supporting shaft 14, the gear 15 and the operating panel 17 fixed on the gear 15 to move up and down, thereby adjusting the height of the engine to a suitable maintenance position.

[0020] When the engine angle needs to be adjusted for more in-depth maintenance, the staff can turn handle 21, which drives shaft 2 19 and gear 20 connected thereto to rotate. Since gear 20 is meshed with gear 15, gear 15 will also rotate accordingly. The rotation of gear 15 will drive the operating plate 17 to rotate, thereby adjusting the engine angle. After adjusting the engine angle, in order to keep it stable, the staff can tighten the locking bolt 22. The bottom end of the locking bolt 22 abuts against the outer wall of shaft 2 19. When the locking bolt 22 is tightened, it will limit the rotation of shaft 2 19, thereby locking the angle of the operating plate 17.
