[0035] Referring to Figures 1-6As shown, the outer active connection of the guide rod 403 has a spring 406, one end of the spring 406 is fixedly connected with the connecting block 401, and the other end of the spring 406 is fixedly connected with the magnetic metal block 404.

[0036] Referring to Figures 1-6 As shown, the outer active sleeve of the magnetic metal block 404 is provided with a positioning ring 407, the lower end of the positioning ring 407 is fixedly connected with a flagpole 408, and the outer end of the flagpole 408 is fixedly connected with a red flag 409.

[0037] By setting the flag hanging assembly 4, the induction card is in contact with the corresponding card swiping induction switch 2, the opening and closing of the electromagnet 402 is controlled, when the electromagnet 402 is powered on, a strong magnetic field is generated, the positioning ring 407 is aligned with the electromagnet 402, the strong magnetic field attracts the magnetic metal block 404 out of the connecting block 401 and stretches the spring 406, the positioning ring 407 is matched with the magnetic metal block 404, so that the magnetic metal block 404 can penetrate the positioning ring 407, and then is firmly adsorbed with the electromagnet 402, that is, the flag hanging is completed, when the electromagnet 402 is powered off, the magnetic metal block 404 loses the magnetic attraction, and under the action of the spring 406, the magnetic metal block 404 is retracted into the connecting block 401 along the guide rod 403, the positioning ring 407 loses the support of the magnetic metal block 404, and can be separated from the lamp holder 303, so as to automatically take down the red flag 409 when the red flag 409 is damaged or needs to be replaced, and the limiting sheet 405 can prevent the magnetic metal block 404 from separating from the guide rod 403.

[0038] Specific implementation process: the electric control box 1 is fixed on the lower side of the two-layer platform at a predetermined position, the power supply is connected and the communication link is debugged, the operator triggers the lamp holder 303 to expand through the induction card, the LED red light flashes, and the red flag 409 is hung well;

[0039] The induction card is in contact with the card swiping induction switch 2, the driving motor 301 is turned on, the driving motor 301 drives the transmission shaft 302, the lamp holder 303 and the safety protection lamp body 304 to rotate counterclockwise by ninety degrees, and the lamp holder 303 and the safety protection lamp body 304 can be expanded;

[0040] Then the interlocking is effective, the vehicle control system receives the interlocking signal and prohibits movement, the track signal displays "stop", and after the maintenance is completed, the induction card is in contact with another card swiping induction switch 2, so that the driving motor 301 drives the transmission shaft 302, the lamp holder 303 and the safety protection lamp body 304 to rotate clockwise by ninety degrees, the lamp holder 303 and the safety protection lamp body 304 are automatically retracted, the safety protection lamp body 304 is turned off, and the interlocking is released;

[0041] In addition, by setting the monitoring camera 307, the on-duty room can remotely confirm the protection lamp state through the video image, and the infrared proximity sensor 308 can detect the approach of the locomotive.

[0042] The induction card contacts the corresponding card swiping induction switch 2 to control the opening and closing of the electromagnet 402. When the electromagnet 402 is powered, a strong magnetic field is generated to align the positioning ring 407 with the electromagnet 402. The strong magnetic field attracts the magnetic metal block 404 from the connecting block 401 and stretches the spring 406. The positioning ring 407 is matched with the magnetic metal block 404, so that the magnetic metal block 404 can penetrate the positioning ring 407 and be firmly adsorbed with the electromagnet 402, that is, the flag hanging is completed. When the electromagnet 402 is powered off, the magnetic metal block 404 loses the magnetic attraction, and under the action of the spring 406, it is retracted into the connecting block 401 along the guide rod 403. The positioning ring 407 loses the support of the magnetic metal block 404, and can be separated from the lamp holder 303, so as to automatically take down the red flag 409 when the red flag 409 is damaged or needs to be replaced.
