The maintenance mechanism 1 includes a turntable 7 and a rotating motor 19. The output end of the rotating motor 19 is rotationally connected to a rotating main shaft 24. The rotating main shaft 24 is fixed to the center position of the bottom outer wall of the turntable 7 by screws. The bottom outer wall of the turntable 7 is welded with spherical fixing seats 8 distributed circumferentially. The top outer wall of the turntable 7 is welded with a receiving hopper 17 corresponding to the position of the spherical fixing seats 8. A spherical accommodating seat 21 adapted to the spherical fixing seat 8 is arranged in the spherical fixing seat 8. The bottom outer wall of the spherical fixing seat 8 is provided with uniformly distributed leakage holes 30; A turning plate 29 is welded to the outer wall of one side of the spherical accommodating seat 21. The turning plate 29 penetrates through the spherical fixing seat 8 and is exposed on the side close to the rotating main shaft 24. A support frame 20 is arranged outside the rotating motor 19. The top of the support frame 20 is fixed with circumferentially distributed turning motors 22 by screws. The output end of the turning motor 22 is rotationally connected to a turning head 23. The turning plate 29 is of a linear structure, and the turning head 23 is of a C-shaped structure adapted to the turning plate 29; A guide frame 25 is installed on the bottom outer wall of the turntable 7 through a bracket. The guide frame 25 is flush with the turning plate 29; A flaw detection component is installed on one side of the turntable 7, and a maintenance component is installed on the other side of the turntable 7. The flaw detection component includes a first mounting frame and a storage barrel 5. The storage barrel 5 is fixed to the top outer wall of the first mounting frame by screws. A first nozzle 6 is fixed to the outer wall of one side of the first mounting frame by screws. A first electric control valve is arranged on the first nozzle 6; One end of the first nozzle 6 is connected to the output end of the storage barrel 5; A flaw detection medium is arranged in the storage barrel 5. The flaw detection medium can adopt a flaw detection liquid; By setting structures such as the turntable 7, the storage barrel 5, and the spherical fixing seat 8, when maintaining the parts of the mining equipment, the parts can be placed in the spherical accommodating seat 21, the first electric control valve of the first nozzle 6 is controlled to work, and the flaw detection liquid is output into the spherical accommodating seat 21 to detect the parts. When the turning motor 22 works, it can drive the turning head 23 to rotate. Since the turning head 23 and the turning plate 29 are engaged with each other, the turning of the turning head 23 drives the spherical accommodating seat 21 to rotate in the spherical fixing seat 8 through the turning plate 29, so that the opening of the spherical accommodating seat 21 faces downward, and the flaw detection liquid flows down from the leakage holes 30 of the spherical fixing seat 8. The rotating motor 19 works to drive the turntable 7 to rotate, so that the spherical accommodating seat 21 containing the parts is rotated to one side of the maintenance component, facilitating the user to perform maintenance operations.

[0052] For the convenience of collecting the flaw detection medium; such as Figure 2-6As shown, an annular receiving platform 12 is arranged below the turntable 7, and the outer wall of one side of the annular receiving platform 12 is installed on the outer wall of one side of the support frame 20 through a bracket, and the bottom of the annular receiving platform 12 is connected to the recovery box 10 through a connecting pipe 18, and the recovery box 10 is of a C-shaped structure. The cross-section of the annular receiving platform 12 is of a V-shaped structure, and the position of the annular receiving platform 12 corresponds to the leakage hole 30; by arranging the annular receiving platform 12 and the recovery box 10, the flaw detection liquid flowing down from the leakage hole 30 can flow from the connecting pipe 18 into the recovery box 10 under the guidance of the annular receiving platform 12, thereby realizing the recovery and treatment of the flaw detection liquid, saving resources, and improving practicality and environmental protection.
