[0002] In modern industrial systems, electric motors, as core power equipment, are widely used in key areas such as intelligent manufacturing, petrochemicals, power systems, and rail transportation. Their operational stability directly determines the continuity of production processes, product quality, and operational safety. According to statistics on industrial equipment operation and maintenance, production line downtime caused by motor failures accounts for a significant portion of the total downtime of industrial equipment failures. At the same time, motor overload, short circuits, and other faults can also lead to safety hazards such as equipment burnout and fires, posing a serious threat to personnel and property safety. Therefore, real-time and accurate fault diagnosis and monitoring of motor operating status has become one of the core requirements in the field of industrial equipment operation and maintenance.

[0003] However, in the use of existing technology, when repairing motors, the traditional motor diagnostic device has a relatively simple structure and lacks a limiting structure for the motor during diagnosis. The motor may shake or fall during the repair process, and it is not easy to rotate the motor, which is inconvenient for the staff to diagnose. Therefore, a motor fault diagnosis and monitoring device has been proposed. Utility Model Content

[0014] This motor fault diagnosis and monitoring device supports the motor requiring repair via a support platform. Then, an electric telescopic rod moves a molded block upwards to fit against the lower surface of a clamping block.

Under the limiting action of the guide rod and slide groove, the two clamping blocks move towards the center position to fix and limit the motor requiring repair. Simultaneously, a second motor drives the first gear to rotate, causing the second gear to mesh with the first gear and rotate the support platform and the motor. This allows for convenient adjustment of the detection angle, reduces the labor intensity of workers, and prevents the motor from shaking or falling during the detection process.

[0020] Please see Figure 1-4The present invention provides a technical solution: a motor fault diagnosis and monitoring device, including a workbench 3, a drawer 8 inside the workbench 3, and a support platform 13 rotatably connected inside the workbench 3. The support platform 13 supports the motor that needs to be repaired. A second gear 21 is fixedly connected to the lower surface of the support platform 13. A second motor 19 is fixedly connected to the inner bottom wall of the workbench 3. The output end of the second motor 19 is fixedly connected to a first gear 20 through a coupling. The second motor 19 drives the first gear 20 to rotate. The outer surface of the first gear 20 meshes with the outer surface of the second gear 21.

[0021] The support platform 13 has a limiting groove 23 inside, and a guide rod 27 is fixedly connected inside the limiting groove 23. A sliding groove 28 is also provided inside the limiting groove 23, and two clamping blocks 14 are slidably connected inside the sliding groove 28. The interiors of the two clamping blocks 14 are slidably connected to the outer surface of the guide rod 27. The sliding groove 28 and the guide rod 27 limit the position of the clamping blocks 14. A spring 26 is fixedly connected between the two clamping blocks 14, and the spring 26 is sleeved on the outer surface of the guide rod 27. A molded block 1 is slidably connected inside the limiting groove 23. 6. The upper surface of the mold block 16 contacts the lower surface of the clamping block 14. Through the extrusion contact between the mold block 16 and the clamping block 14, the mold block 16 is extruded and moved towards the middle position. An electric telescopic rod 18 is fixedly connected to the inner bottom wall of the worktable 3. A limit block 17 is fixedly connected to the output end of the electric telescopic rod 18. The outer surface of the limit block 17 is rotatably connected to the inside of the mold block 16. Through the electric telescopic rod 18, the mold block 16 and the limit block 17 are pushed to move up and down under the limiting action of the limit groove 23.

[0022] Among them, a support rod 12 is fixedly connected to the upper surface of the workbench 3, and a camera 24 is fixedly connected to the lower surface of the support rod 12 near the support platform 13. The camera 24 is used to record the maintenance of the motor.

[0023] The upper surface of the workbench 3 is fixedly connected to a motor integrated monitoring instrument 9 (model LWIN-DJ03plus). The front of the motor integrated monitoring instrument 9 is electrically connected to an infrared detector 11 (infrared detector 11 is an Infrared Cameras Inc FMX 400 P) via wires. The upper surface of the workbench 3 is fixedly connected to a support frame 10. The surface of the support frame 10 is in contact with the surface of the infrared detector 11. The support frame 10 serves to limit and support the position of the infrared detector 11.

[0024] The lower surface of the workbench 3 is fixedly connected with four sleeves 2, and a support plate 1 is provided below the workbench 3. The upper surface of the support plate 1 is fixedly connected with four limiting rods 25. The outer surface of each limiting rod 25 is in contact with the inner wall of a sleeve 2. Through the cooperation between the sleeve 2 and the limiting rod 25, the workbench 3 is limited.

[0025] Among them, the upper surface of the support plate 1 is fixedly connected to the limiting box 4, and two sliders 6 are slidably connected inside the limiting box 4. The limiting box 4 serves to limit the position of the sliders 6.

[0026] Each slider 6 has a pull rod 7 rotatably connected to its top end, and a fixing block 22 is fixedly connected to the lower surface of the worktable 3. The interior of the fixing block 22 is rotatably connected to the outer surface of the pull rod 7 at the end away from the slider 6. The pull rod 7 serves to connect the slider 6 and the fixing block 22.

[0027] The support plate 1 has a first motor 15 fixedly connected to its upper surface. The output end of the first motor 15 is fixedly connected to a bidirectional threaded rod 5 via a coupling. The first motor 15 drives the bidirectional threaded rod 5 to rotate.

[0028] Both ends of the outer surface of the bidirectional threaded rod 5 are rotatably connected to the inside of the limiting box 4. The outer surfaces of both ends of the bidirectional threaded rod 5 are respectively connected to the internal threads of the two sliders 6, and the internal threads of the two sliders 6 are respectively adapted to the threads of the outer surfaces of both ends of the bidirectional threaded rod 5. Through the two bidirectional threaded rods 5, the two sliders 6 are moved to the middle position.

[0029] The motor is existing technology and will not be discussed in detail here. The components that match the motor include connecting wires, power supply, and microcontroller, which are also existing structures and will not be discussed in detail here.

[0030] Working Principle: In operation, firstly, the first motor 15 is started, driving the bidirectional threaded rod 5 to rotate. This causes the bidirectional threaded rod 5 to engage with the internal threads of the two sliders 6, moving them towards the center under the limiting action of the limiting box 4. This causes the two pull rods 7 to push the worktable 3 upwards, and the sleeve 2 to move upwards under the supporting and limiting action of the limiting rod 25. The height of the worktable 3 is optimal for the operator's convenience. Then, the motor to be inspected is placed on the upper surface of the support platform 13. The electric telescopic rod 18 is started, pushing the limiting block 17 and the molded block 16 upwards. The molded block 16 moves upwards and contacts the lower surface of the clamping block 14, pressing against the bottom inclined surface of the clamping block 14. Under the limiting action of the slide groove 28 and the guide rod 27, the two clamping blocks 14 compress the spring 26, moving it towards the center. The motor is pressed and fixed, limiting its position. When the motor's placement angle needs to be adjusted, the second motor 19 is started, driving the first gear 20 to rotate. This causes the first gear 20 to mesh with the second gear 21, rotating the support platform 13 and the motor placed on top of it. The placement angle of the motor is then adjusted. At this time, the motor monitoring instrument 9 is connected to the motor using a connecting wire to test whether the internal circuitry of the motor is normal. An infrared detector 11 can be held in hand and used to scan the motor. In conjunction with the motor monitoring instrument 9, it can be observed whether there is localized high temperature in the motor during the wiring process, thus promptly identifying any abnormalities in the internal circuitry of the motor. Simultaneously, the camera 24 is activated during motor disassembly to record the disassembly process for later motor reassembly.
