[0043] Working principle:

[0044] Start the motion motor 48, which drives the motion rotating shaft 29 to rotate, thereby driving the motion wheel 19 to rotate, thus driving the support frame 18 to move, and then driving the inspection platform 1 to move. When a turn is required, start the steering motor 46, which drives the rotating shaft 47 to rotate, thereby driving the support frame 18 to rotate, thus achieving a change in direction. Start the auxiliary motor, which drives the auxiliary lead screw 21 to rotate, thereby driving the auxiliary nut block 50 to move. As the auxiliary nut block 50 moves, it drives the limiting slider 39 to slide in the limiting groove 38, thereby increasing the stability of the auxiliary nut block 50. After clamping the pipe fitting equipment, the auxiliary motor moves, driving the auxiliary nut block 50 to move to the position in the middle of the rotating cylinder 7. Start the driving motor 37, which drives the gear shaft 40 to rotate, thereby driving the driving gear 41 to rotate. The driving gear 41 meshes with the driven gear 36, driving the lifting lead screw 34 to rotate. The lifting lead screw 34 is threadedly connected to the lifting plate 23, driving the lifting plate 23 to move up and down, facilitating the clamping of the pipe fitting equipment. Start the clamping motor, which drives the clamping lead screw 27 to rotate. The clamping lead screw 27 is threadedly connected to the clamping chute 26, driving the clamping nut block 16 to move, thus driving the fixing plate 3 to move to the corresponding position. Energize the electric push rod 14, driving the fixing plate 3 to move, and then driving the electric gripper 2 to contact the pipe fitting equipment. Energize the electric gripper 2 to clamp the pipe fitting equipment. After clamping, the clamping motor moves, driving the clamping nut block 16 to move, thus driving the fixing plate 3 to move, and then driving the pipe fitting equipment to move to the position between the rotating cylinders 7, facilitating clamping and rotation for maintenance. Start the moving motor 32, which drives the moving lead screw 13 to rotate. The moving lead screw 13 is threadedly connected to the moving nut block 31, driving the moving nut block 31 to move, and then driving the moving frame 25 to move. By adjusting the distance between the moving frames 25, it can adapt to pipe fitting equipment of different lengths. Start the clamping motor, which drives the clamping lead screw 5 to rotate. The clamping lead screw 5 is threadedly connected to the clamping nut block 30, driving the clamping nut block 30 to move, thus driving the rotating table 6 to move, making the rotating tables 6 move closer to each other, and then driving the rotating cylinders 7 to move to clamp the pipe fitting equipment. After the rotating cylinders 7 clamp the pipe fitting equipment, start the rotating motor 45, which drives the rotating gear shaft 44 to rotate, thereby driving the rotating gear 43 to rotate. The rotating gear 43 meshes with the annular rack 9, driving the annular rack 9 to rotate, and then driving the rotating cylinder 7 to rotate, thus rotating the pipe fitting equipment. By adjusting the distance between the rotating cylinders 7, it is possible to clamp pipe fitting equipment of different diameters and drive the pipe fitting equipment to rotate, facilitating the maintenance of the pipe fitting equipment. When the moving frame 25 moves, it drives the stable slider 22 to slide in the stable chute 11, thereby increasing the stability of the moving frame 25.
