The setting of the traction inverter introduction conveyor belt 3 and the traction inverter adjustment component 5 enables the traction inverter to be detected to enter the locomotive traction inverter detection equipment through a scientific and automated process, while saving manpower and improving efficiency, avoiding secondary damage to the traction inverter caused by staff contact, and the traction inverter is automatically removed through the traction inverter cover removal component 7 after entering the locomotive traction inverter detection equipment. The removal and installation work can improve the efficiency while avoiding the dust in the air and the harsh conditions in the outside world from damaging the components in the traction inverter during the removal process. The corresponding detector 63 can be selectively installed on the traction inverter detection component 6 of the traction inverter detection equipment of this locomotive, and the corresponding detector 63 can be deleted or adjusted according to different situations, so as to more efficiently perform the detection work of the traction inverter. The multi-model screwdriver holder 11 can provide a wider range of screwdriver models for the traction inverter removal cover component 7, so that the traction inverter removal cover component 7 can meet the removal and installation work of different models of traction inverter covers. The traction inverter bearing positioning component 55 will adjust the position of the traction inverter so that it can be located at the center of the conveyor belt 34, so as to facilitate the subsequent work.

The locomotive traction converter detection device according to claim 4, characterized in that: The disassembly assembly (73) comprises: a sliding plate (731), the lower end of which is vertically fixed with two connecting and fixing columns (732), the lower ends of the two connecting and fixing columns (732) are fixedly equipped with a fixed strip plate (733), one side of the fixed strip plate (733) is fixedly equipped with a fifth track (734), and the fifth track (734) is slidably equipped with a bolt rotating disassembler (735) and a bolt storage (736); the other side of the fixed strip plate (733) is fixedly equipped with a hydraulic telescopic column (738), and the lower end of the hydraulic telescopic column (738) is fixedly equipped with a fixed suction cup (739); and a visual positioning module (737) is fixedly arranged on the upper surface of the fixed strip plate (733).

6. A method for using a locomotive traction converter detection device, which uses the locomotive traction converter detection device as claimed in claim 5, characterized in that: The following steps are involved: S1. The traction inverter to be tested is transported to the traction inverter inlet conveyor belt (3) through the traction inverter input roller (2), and then the closed door (4) is opened; S2. Four automatic sliders (33) drive the conveyor belt (34) and the traction inverter thereon to move to the traction inverter positioning assembly (5), and then the closed door (4) is closed; S3. The traction inverter carrying positioning assembly (55) adjusts the position of the traction inverter and is raised to the limit height of the traction inverter positioning assembly (5) under the drive of the first drive motor (51); S4. The temperature and humidity controller (9) adjusts the temperature and humidity in the closed dustproof shell (1), and the pressure regulator (10) adjusts the pressure in the closed dustproof shell (1), wherein the temperature, humidity and pressure meet the detection requirements and are kept constant, and at the same time, the bolt rotating disassembler (735) and the bolt storage (736) complete the removal of the bolts of the traction inverter protection cover under the guidance of the visual positioning module (737); S5. The hydraulic telescopic column (738) drives the fixed suction cup (739) to fix the traction inverter protection cover and separate it from the traction inverter; S6. After the traction inverter is separated from the protection cover, the second drive motor (58) drives the traction inverter carrying positioning assembly (55) and the traction inverter thereon to rotate to a corresponding angle so that it corresponds to the corresponding detector (63); S7. The four automatic slide blocks (33) drive the conveyor belt (34) and the traction inverter thereon to move to the lower end of the corresponding detector (63) and complete the detection; S8. The four automatic The movable slider (33) drives the conveyor belt (34) and the traction inverter thereon to return to the original position, and rotates to a corresponding angle under the drive of the second drive motor (58) so that it corresponds to the next group of detectors (63); S9. S6-S8 are repeated until all the detection of the traction inverter is completed and the second drive motor (58) is rotated to the initial angle; S10. The hydraulic telescopic column (738) drives the fixed suction cup (739) to place the traction inverter protection cover on the traction inverter; S11. The bolt rotation remover (735) and the bolt storage (736) complete the installation of the traction inverter protection cover bolts under the guidance of the visual positioning module (737); S12. The traction inverter returns to the initial position with the conveyor belt (34) under the action of the traction inverter positioning assembly (5); S13. The conveyor belt (34) is started to transport the traction inverter to the traction inverter output roller (8), and corresponding processing is performed according to its detection result.
