[0023] The protective lamp mounting seat 3 and the light flag socket 4 are both arranged on the top of the support cover 2. When performing maintenance work at night, the protective lamp 8 is used for warning. At this time, the protective lamp mounting seat 3 is used to load the protective lamp 8, and the warning effect is more obvious. When performing maintenance work during the day, the light flag 7 can be plugged into the light flag socket 4. Compared with the protective lamp 8, it has lower energy consumption and is more conspicuous.

[0024] The top of the support cover 2 is provided with a mounting groove 23, and the protective lamp mounting seat 3 is arranged in the mounting groove 23, specifically, it is screwed on the support cover 2 by screws. The protective lamp mounting seat 3 is provided with a wire groove, and the power line drawn from the inside of the support cover 2 passes through the wire groove and is connected to the socket on the protective lamp mounting seat 3. The protective lamp 8 can be connected to the protective lamp mounting seat 3 by magnetic attraction, or it can be installed on the protective lamp mounting seat 3 by buckle or screw.

[0025] A cover plate 21 is provided at the notch of the installation slot 23, and the cover plate 21 is hinged to the support cover 2. When the cover plate 21 is closed, the notch of the installation slot 23 is sealed. Furthermore, a sealing strip or the like can be used to achieve sealing. When the protective lamp 8 is not needed, it is removed and the cover plate 21 is closed.

[0026] The light flag socket 4 includes a column base 401 , a telescopic rod 402 and a column sleeve 403 .

[0027] The column base 401 is arranged on the top of the support cover 2. The telescopic rod 402 can realize telescopic and positioning after telescopic, and any telescopic positioning rod structure in the prior art can be adopted, and the telescopic rod 402 is arranged on the column base 401. The column sleeve 403 is arranged at the end of the telescopic rod 402, that is, by adjusting the length of the telescopic rod 402, the height of the column sleeve 403 can be adjusted, so that the height of the light flag 7 can be adjusted according to actual conditions. Among them, the column sleeve 403 is adapted to the flagpole of the light flag 7, and the adaptation means that the flagpole of the light flag 7 can be completely inserted into the column sleeve 403, and preferably, the two are interference fit.

[0028] An extension platen 22 is provided at the opening of the support cover 2, and screw holes are provided on the extension platen 22 and the suction base 1, so that the support cover 2 and the suction base 1 can be connected as a whole by bolts, and the extension platen 22 and the suction base 1 are fitted after the connection. In order to ensure the sealing, a sealing gasket 24 is sandwiched between the extension platen 22 and the suction base 1, and the design of the extension platen 22 enables the sealing gasket 24 to have an installation position, that is, there is enough contact area between the support cover 2 and the suction base 1 to place the sealing gasket 24. The above structural design has the following advantages: first, it can ensure the sealing of the internal space of the support cover 2; second, it improves the convenience of assembling the support cover 2 and the suction base 1; third, the stability of the two after assembly is also higher, which can cope with the impact force when falling to the ground.

[0029] The inner space of the support cover 2 is provided with a time controller 5, a micro control unit 9, a voltage inverter 10, a lithium battery 11, and basic circuit structures such as a drive board and a circuit board.

[0030] The power-off type electromagnet 6 is arranged at the bottom of the suction base 1, and can be sucked on the side of the front and rear bodies of the railway vehicle when it is not powered. The time controller 5 is arranged on the power supply circuit of the power-off type electromagnet 6, and specifically, the time controller 5 is arranged on the power supply circuit between the power supply and the power-off type electromagnet 6. The power supply includes: a voltage inverter 10 and a lithium battery 11, the input side of the voltage inverter 10 is connected to the lithium battery 11, and the voltage inverter 10 converts the voltage output by the lithium battery 11, converts it into a voltage value that can be used by other devices and outputs it. The micro control unit 9, the time controller 5, the protective light 8, and the parameter setting keyboard 12 are connected to the output side of the voltage inverter, that is, the voltage inverter provides the working voltage for the above-mentioned devices.

[0031] The time controller 5 can be any existing functional device that can perform timing and trigger a certain action when the timing is reached. The functional device is connected to a switch, and the switch is set on the power supply circuit of the power-off type electromagnet 6.

[0032] The parameter setting keyboard 12 is connected to the signal input end of the micro control unit 9, and the time controller 5 is connected to the control output end of the micro control unit 9. The timing time of the time controller 5 is set through the parameter setting keyboard 12.

The train inspection operation time is divided into the main train inspection station. The total technical maintenance operation time for the arrival and departure of the train is 1h in principle; the maintenance time for the transit train without adjustment is 35min; the maintenance time for the transit train with adjustment is 40min. According to different operations and different needs on site, different time controllers 5 are set. After 35 minutes or 40 minutes of use, the power-off type electromagnet 6 is automatically energized, the magnetism fails, and it automatically falls off the car body, effectively solving the problem of railway accidents caused by the omission of light flags, better ensuring the driving safety and personal safety of railway trucks, and ensuring smooth and orderly truck transportation.

[0033] Due to frequent automatic falling off, the structural strength needs to be ensured. Based on the design of the support cover 2 and its connection method, this embodiment sets a buffer mechanism at the outer corner of the support cover 2 to avoid problems such as structural looseness and poor contact of components caused by frequent falling. It has the advantages of stable structure, high strength, and suitable for use in harsh environments. The buffer mechanism is composed of a folding plate 111 and an elastic member 222, one end of the elastic member 222 is connected to the support cover 2, and the other end is connected to the folding plate 111.

[0034] The side cover on one side of the support cover 2 is recessed inward to form a sinking groove 25, and a through groove is provided at the bottom of the sinking groove 25. The parameter setting keyboard 12 is located in the through groove, which can avoid damage to the parameter setting keyboard 12 caused by frequent falling and facilitate personnel to set parameters.

[0035] A railway train inspection safety protection red light device of this embodiment also includes: an external charging socket 13, an external power switch 14 and an external indicator light 15. The external charging socket 13 is connected to the lithium battery 11, and is used to connect an external power source to charge the lithium battery 11. The external power switch 14 and the time controller 5 are both arranged on the power supply circuit between the power supply and the power-off type electromagnet 6. Pressing the external power switch 14 can directly connect the power supply circuit of the power-off type electromagnet 6 to prevent the defect that the safety protection red light device cannot be removed due to the early completion of the inspection. The external indicator light 15 is connected to the output side of the voltage inverter 1 to reflect the power supply status.

[0036] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed by the utility model should be included in the protection scope of the utility model.
