[0036] Specifically, during testing, the electric telescopic rod 301 is activated, which moves the mounting bracket 302 and the fixed frame 303 to the outside of the relay housing 8. At this time, the telescopic spring 309 allows the fixing suction cup 308 to contact the outer wall of the relay housing 8. The air pump 307 is then activated, and the air pump 307 expels air from the connecting pipe 311 through the connecting pipe 306, thereby expels air from the fixing suction cup 308, thus fixing the fixing suction cup 308 to the relay housing 8. Then, the drive motor 313 is activated, which drives the transmission rod 314 to rotate, thereby expels air from the connecting pipe 311 and the outer wall of the relay housing 8. 14 drives the disassembly head 318 to rotate, thereby disassembling the threaded part 305. At this time, the transmission rod 314 can drive the drive gear 312 to rotate. Since the drive gear 312 meshes with the driven gear 319, the drive motor 313 can drive the driven gear 319 to rotate. Since the transmission gear 515 meshes with the gear plate 321, the driven gear 319 can drive the connecting plate frame 322 to move, thereby moving the drive motor 313 until the threaded part 305 is separated from the threaded hole 9, completing the disassembly. The electric telescopic rod 301 starts to drive the relay housing 8 to separate from the relay body 4.

[0037] In specific application scenarios, the convenient testing module 3 is suitable for the disassembly and installation of relay test housings.

A limiting rod 502 is fixedly connected to the inner walls of both sides of the mounting base 501. A lead screw 509 is connected to the inner walls of both sides of the mounting base 501 via bearings. Two movable supports 508 are provided on the outer walls of the lead screw 509 and the limiting rod 502. A fixing frame 506 is fixedly connected to the top of each of the two movable supports 508, and each of the two movable supports 508 has a circular hole at its top. Data blocks 505 are fixedly connected inside each of the two circular holes, and data lines 504 are fixedly connected to the bottom of each of the two data blocks 505.

[0039] Specifically, during testing, stepper motor 503 is started, driving lead screw 509 to rotate. Lead screw 509 then moves two movable supports 508 to opposite sides. Simultaneously, power motor 507 is started, driving transmission gear 515 to rotate. Since transmission gear 515 meshes with external gear plate 512, it drives hollow rod 511 to move on mounting piece 513 until one of the contact probes 510 moves outside the fixed frame 506. The resistance test continues until the contact test piece 510 contacts the outer wall of the resistance contact 10 to perform a resistance test. The test data is then transmitted to the test equipment body 1 via the connection line 514, data block 505, and data line 504. After the test of the contact is completed, the power motor 507 is restarted. The power motor 507 can simultaneously drive the two outer toothed plates 512 to move in opposite directions, thereby moving the other contact test piece 510 out of the fixed frame 506 and contacting the other end of the resistance contact 10 for testing. The test is completed and the device is reset.

[0040] In specific application scenarios, the resistance testing module 5 is suitable for the resistance testing of the resistance contact 10. Specifically, the resistance testing module 5 can automatically connect with the resistance contact 10 during use, eliminating the need for manual connection of the contact test piece 510. Furthermore, during resistance testing, the resistance testing module 5 can quickly switch between different contact test pieces 510, allowing for rapid testing of the next resistance contact 10 after the previous one has been tested, further increasing the ease of use of the device. After testing, the resistance testing module 5 can quickly transmit the data to the test equipment body 1 via the connection line 514, data block 505, and data line 504 for data analysis.

The output ends of the two delivery pumps 712 are fixedly connected to delivery pipes 707. The output ends of the two delivery pipes 707 are connected to the interior of the airbag component 703.

[0042] Specifically, the test equipment body 1 is moved to the relay to be tested, and the delivery pump 712 is started. The delivery pump 712 delivers air to the airbag component 703 through the air inlet pipe 710 until the airbag component 703 drives the movable plate frame 704 to descend, so that the stabilizing suction cup 706 contacts the ground. At this time, as the delivery pump 712 runs, the stabilizing suction cup 706 is attached and fixed to the ground. After the fixation is completed, the control valve 709 on the stabilizing air pipe 705 is closed, and the control valve 709 on the air inlet pipe 710 continues to open, so that the airbag component 703 is inflated to adjust the height of the test equipment body 1.

[0044] A testing method for a subway relay testing device, using the subway relay testing device as described above, includes the following steps:

[0045] Step 1: Move the test equipment body 1 to the relay to be tested, start the delivery pump 712, the delivery pump 712 delivers air to the airbag 703 through the air inlet pipe 710 until the airbag 703 drives the movable plate frame 704 to descend, so that the stabilizing suction cup 706 contacts the ground. At this time, as the delivery pump 712 runs, the stabilizing suction cup 706 is attached and fixed to the ground. After the fixation is completed, the control valve 709 on the stabilizing air pipe 705 is closed, and the control valve 709 on the air inlet pipe 710 continues to open, so that the airbag 703 is inflated to adjust the height of the test equipment body 1. After the adjustment is completed, the control valve 709 on the air inlet pipe 710 is closed.

[0046] Step 2: During testing, the electric telescopic rod 301 is activated. The electric telescopic rod 301 moves the mounting bracket 302 and the fixing frame 303 to the outside of the relay housing 8. At this time, the telescopic spring 309 allows the fixing suction cup 308 to contact the outer wall of the relay housing 8. The air pump 307 is then activated, and the air pump 307 expels air from the connecting pipe 311 through the connecting pipe 306, thereby expels air from the fixing suction cup 308, thus fixing the fixing suction cup 308 to the relay housing 8. Then, the drive motor 313 is activated, driving the transmission rod 314 to rotate, thereby expels air from the connecting pipe 311 and the outer wall of the relay housing 8. 14 drives the disassembly head 318 to rotate, thereby disassembling the threaded part 305. At this time, the transmission rod 314 can drive the drive gear 312 to rotate. Since the drive gear 312 meshes with the driven gear 319, the drive motor 313 can drive the driven gear 319 to rotate. Since the transmission gear 515 meshes with the gear plate 321, the driven gear 319 can drive the connecting plate frame 322 to move, thereby moving the drive motor 313 until the threaded part 305 is separated from the threaded hole 9, completing the disassembly. The electric telescopic rod 301 starts to drive the relay housing 8 to separate from the relay body 4.

[0047] Step 3: During testing, start the stepper motor 503. The stepper motor 503 drives the lead screw 509 to rotate, which in turn drives the two movable supports 508 to move to opposite sides. Simultaneously, start the power motor 507, which drives the transmission gear 515 to rotate. Since the transmission gear 515 meshes with the external gear plate 512, it drives the hollow rod 511 to move on the mounting piece 513 until one of the contact measuring pieces 510 moves outside the fixed frame 506. The resistance test continues until the contact test piece 510 contacts the outer wall of the resistance contact 10 to perform a resistance test. The test data is then transmitted to the test equipment body 1 via the connection line 514, data block 505, and data line 504. After the test of the contact is completed, the power motor 507 is restarted. The power motor 507 can simultaneously drive the two outer toothed plates 512 to move in opposite directions, thereby moving the other contact test piece 510 out of the fixed frame 506 and contacting the other end of the resistance contact 10 for testing. The test is completed and the device is reset.

[0048] Step 4: After testing, restart the convenient testing module 3 to reset and install the relay housing 8. After installation, the moving device will perform the next test operation on the relay body 4.
