[0002] Relays mainly realize circuit control by closing and opening contacts. Relays are one of the basic equipment of urban rail transit signal systems. Relays play the role of automatic adjustment, safety protection, and circuit conversion in the circuit.

Or the relay failure may be caused by disconnection of the relay winding coil or poor soldering. Therefore, as the use time of the relay gradually increases, if it is not tested, the danger will increase. Moreover, the relay is a key component, so it is necessary to perform diagnostic tests on the relay regularly to ensure the performance of the relay in use.

[0045] Step 1, move the test equipment body 1 to the relay to be tested, start the delivery pump 712, and the delivery pump 712 delivers air to the inside of the airbag part 703 through the air inlet pipe 710 until the airbag part 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 adsorbed 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 be opened, so that the airbag part 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 the test, the electric telescopic rod 301 is started, and the electric telescopic rod 301 drives the mounting bracket 302 and the fixed frame 303 to move to the outside of the relay housing 8. At this time, the telescopic spring 309 can make the fixed suction cup 308 contact the outer wall of the relay housing 8, and the air pump 307 is started. The air pump 307 discharges the air inside the connecting pipe 311 through the connecting pipe 306, and then discharges the air inside the fixed suction cup 308 through the connecting pipe 311, so that the fixed suction cup 308 fixes the relay housing 8, and then the driving motor 313 is started, and the driving motor 313 drives the transmission rod 314 to rotate, and then the transmission rod 314 is driven to rotate. 14 drives the disassembly head 318 to rotate, so that the disassembly head 318 disassembles the threaded member 305, and at this time, the transmission rod 314 can drive the driving gear 312 to rotate when rotating, and since the driving gear 312 is meshed with the driven gear 319, the driving motor 313 can drive the driven gear 319 to rotate, and since the transmission gear 515 is meshed with the gear plate 321, the driven gear 319 can drive the connecting plate frame 322 to move, so that the driving motor 313 moves until the threaded member 305 is separated from the threaded hole 9, and the disassembly is completed, and the electric telescopic rod 301 starts to drive the relay housing 8 to separate from the relay body 4;

[0047] Step 3: During the test, the stepper motor 503 is started, and the stepper motor 503 drives the screw rod 509 to rotate, and then drives the two movable brackets 508 to move to the opposite side through the screw rod 509. At the same time, the power motor 507 is started, and the power motor 507 drives the transmission gear 515 to rotate. Since the transmission gear 515 is meshed with the outer tooth plate 512, the transmission gear 515 can drive the hollow rod 511 to move on the mounting member 513 until one of the contact test pieces 510 moves to the outside of the fixed frame 506. Until the contact test piece 510 contacts the outer wall of the resistance contact 10 to perform resistance testing, and the test data is transmitted to the test device body 1 through the connecting line 514, the data block 505 and the data line 504. After the test of the tissue contact is completed, the power motor 507 is started again, and the power motor 507 can simultaneously drive the two outer tooth plates 512 to move in the opposite direction, so that the other contact test piece 510 moves out of the fixing frame 506 and contacts the other end of the resistance contact 10 for testing, until the test operation is completed and the device is reset;

[0048] Step 4: After the test, the convenient test module 3 is started again to reset and install the relay housing 8, and after installation, the mobile device performs the detection operation of the next relay body 4.
