[0030] The invention provides an intelligent maintenance system for a traction motor.

[0031] like Figure 1-3 As shown, the intelligent maintenance system for traction motors provided in an embodiment of the present invention includes a motor maintenance part 10 and a motor disassembly and assembly part 20. The main parts are arranged on the ground, and the bottoms of the motor maintenance part 10 and the motor disassembly and assembly part 20 are equipped with Forma wheels to facilitate the movement of the equipment.

[0032] The motor maintenance unit 10 includes a platform 15, a material display board 11, a maintenance operation display screen 12, a tool control module 14, and a material control module 13. The material display board 11 can hang maintenance operation tools through the mounting holes, and the maintenance operation display screen 12 has a built-in training management system, and can demonstrate the traction motor disassembly operation, maintenance operation, and detection operation process through three-dimensional simulation, pictures or videos combined with corresponding process text descriptions, to assist the training teachers in teaching.

[0033] The motor disassembly and assembly section 20 includes a support bracket 21, a stator rotation assembly 22, a rotation locking mechanism, a motor moving slide 23, a stator and rotor separation tool 25, a rotor support tool 24, and a motor end cover storage tool 26. The motor disassembly and assembly section 20 can realize 360° rotation during the disassembly / assembly process of the motor and the rotor, and trainees can perform maintenance operations on the motor from multiple angles.

[0034] Specifically, the traction motor is placed on the stator rotating assembly 22, and the stator rotating assembly 22 rotates with the traction motor to realize the inspection of the appearance of the traction motor and the inspection before the motor is disassembled;

[0035] According to the instructions displayed on the maintenance operation display screen 12 in the training management system, the traction motor is disassembled on the load-bearing bracket 21;

[0036] The stator and rotor separation operation is performed by the stator-rotor separation tool 25. After the rotor is pulled out from the stator, the rotor support tool 24 is lifted by the cylinder and then supports the rotor, so that the rotor and stator of the traction motor can be inspected and repaired.

[0037] The training management system includes an integrated training management platform, a smart reservation system, a scoring management system, a "learning, practicing, and testing" system, an expert guidance system, and a visual inspection system. It conducts information management from the five major elements of "people, machines, materials, methods, and testing", and interconnects the subsystems to build a complete training management information system, which can provide basic data such as training time and results, and provide strong support for the implementation of the smart management platform for training teaching.

[0038] The smart training management system includes the student side and the instructor side. The student side includes functions such as appointment management, score inquiry, and score statistical analysis; the instructor side includes training task management, equipment management, material management, training record management, scoring management, and score analysis management.

[0039] Appointment management enables students to manage their own appointments. After students log in and check in through the smart all-in-one machine, the system automatically displays the training tasks and workstations based on the appointment status. Learners conduct independent training, realizing dynamic management of the training process and intelligent allocation of training resources and time.

[0040] The user can check the equipment status, network connection status and trainee operation status in real time through the system, and keep abreast of the progress of practical training. At the same time, the system monitors the equipment's operating status, reservation occupancy status, online status, fault status, and location in real time, thus improving the management efficiency of practical training equipment.

[0041] The "learning, practicing, and testing" system and the expert guidance system are used for students to learn, train, and test independently, thereby improving students' learning efficiency and the efficiency of using training equipment. The training area is equipped with three modules: learning mode, practice mode, and assessment mode according to the corresponding training content.

[0042] Learning mode: Students conduct basic learning through expert guidance on component structure and principle analysis, operation content analysis and other related contents combined with real equipment on site, with emphasis on component recognition, action principles, safety precautions and other contents.

[0043] Practice mode: guide trainees to use the specific work content in the expert guidance system according to the work step requirements and combine with the practical training equipment to learn and do one step at a time, and at the same time focus on weak projects. It aims to emphasize equipment operation training, strengthen the work process, and familiarize with process standards.

[0044] Assessment mode: The intelligent scoring system is used to comprehensively evaluate the students' training process. Students are required to complete the training projects independently without the guidance of an expert system. Students can fully master the requirements of the training content, meet the needs of the job requirements, and fully master the training process requirements.

[0045] In the above embodiment, the motor maintenance unit 10 further includes a material control module disposed on the platform 15 , and the material control module is provided with a sensing grating and a visual inspection camera, and the sensing grating and the visual inspection camera are both disposed toward the platform 15 .

[0046] High-resolution visual inspection cameras or sensors are used to capture images of products and user operations. The captured images are then preprocessed, including denoising and enhancement, to improve image quality. Next, image processing algorithms are used to extract features from the image, such as edges, shapes, colors, quantities, etc. Finally, the extracted features are compared and analyzed with preset standards or templates to determine whether the product is taken incorrectly or the quantity taken does not meet the requirements.

[0047] The specific operation steps are as follows: When the trainee takes the material, he / she reaches into the material control module to take the material. At this time, the sensor grating will sense the movement of the human hand and trigger the visual inspection camera. The lighting system will turn on and the visual inspection camera will start shooting synchronously. The photo data will be uploaded to the memory of the industrial computer for subsequent processing and analysis. The extracted features will be compared and analyzed with the preset standards or templates to determine whether the product is taken incorrectly or the quantity taken does not meet the requirements.

[0048] Based on the above embodiment, in the present application, the traction motor is first placed on the stator rotating assembly 22 on the supporting bracket 21. The stator rotating assembly 22 can rotate with the motor. A motor moving slide 23 is provided on the stator rotating assembly 22 to realize the inspection of the appearance of the traction motor and the motor before disassembly. Then, according to the software instructions in the training management system (specifically displayed on the maintenance operation display screen 12), the traction motor is disassembled on the motor disassembly and assembly part 20.

[0049] When performing the disassembly operation, first take the corresponding tools from the tool control module 14 to remove the motor's speed measuring gear cover, speed measuring gear and N-end end cover, and then use the stator-rotor separation tooling 25 to perform the stator-rotor separation operation. After the rotor is pulled out of the stator to a certain position, the rotor support tooling 24 is lifted by the cylinder and then the rotor is supported by the rotor support tooling 24, so as to carry out the inspection of the traction motor rotor and the inside of the stator; the disassembled speed measuring gear, N-end end cover and other components and fastening screws are placed in the material control module 13 of the motor maintenance part 10.

[0050] In the present application, during disassembly, the stator and rotor separation operation that is too heavy to be manually operated is performed by the cooperation of the stator and rotor separation tooling 25 and the rotor support tooling 24, thereby improving the maintenance efficiency of the traction motor.

[0051] At the same time, all parts that need to be disassembled, such as the motor end cover and motor rotor, are designed to be lightweight, made of aluminum alloy or cavity structure, and can be disassembled directly by hand. Sufficient clearance is reserved for the parts that need to be disassembled, making it easy to disassemble and assemble the equipment, reducing the weight by two-thirds while ensuring the structural shape and strength.

[0052] The above description is only a preferred embodiment of the present invention, and does not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the concept of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
