[0002] With the rapid development of rail transit, various types of subway track doors have been applied in rail transit engineering. Generally, subway track doors can be divided into electric and pneumatic types according to their power source. Common subway track doors include concealed doors, external doors, sliding doors, and outward swing doors. With the development of technology, the intelligentization of subway track doors is becoming increasingly popular.

[0003] Currently, subways, as an important part of urban public transportation, carry a massive daily passenger flow, making their safe operation crucial. Existing subway track safety doors mostly use infrared or contact sensors to achieve anti-pinch functions. However, infrared sensors are easily interfered with by strong light and obstructions from foreign objects, resulting in blind spots. Contact sensors can only trigger the anti-pinch mechanism after an obstacle comes into direct contact with the door, failing to provide early warnings. This seriously affects passenger safety and significantly reduces subway operating efficiency. Therefore, we propose a subway track safety door to solve the above problems. Utility Model Content

[0022] A subway track safety door includes a door body 7. Two limiting grooves 18 are formed on the inner wall of the door body 7. Two sets of moving wheels 20 are slidably connected to the inner walls of each limiting groove 18. A mounting seat 19 is engaged on the outer surface of each moving wheel 20. A door body 11 is mounted on one side of each set of mounting seats 19 that is close to each other. A groove 13 is formed on the outer surface of the door body 7. A mounting sealing gasket 14 is engaged on the inner wall of the groove 13. Two mounting slots 21 are formed inside the door body 7. Two electro-hydraulic telescopic rods 22 are connected to one side of each mounting slot 21 that is close to each other. After receiving an opening command, the main controller 1 controls the electro-hydraulic telescopic rods 22 to retract, pushing the adapter plate 23 to slide the door body 11 to both sides to open. At this time, the status indicator light 3 turns green. When the light illuminates and the train prepares to leave the station, the main controller 1 controls the electric hydraulic telescopic rod 22 to retract, pushing the adapter plate 23 to slide the door 11 towards the center to close. After closing, the status indicator light 3 turns red. During the closing process, the pressure sensor 10 on the back of the door 11 monitors the resistance in real time. Once abnormal pressure caused by trapping a person or object is detected, a signal is transmitted to the main controller 1. The main controller 1 then controls the electric hydraulic telescopic rod 22 to extend in the opposite direction, causing the door 11 to reopen. At the same time, the status indicator light 3 flashes as an alarm. In case of an emergency, staff or passengers can press the emergency stop switch 4 on the front of the main controller 1 to cut off the power to the electric hydraulic telescopic rod 22, causing the door 11 to stop immediately. This ensures that the door 11 slides smoothly and is accurately positioned, reducing jamming and wear.

[0023] In this embodiment, a main controller 1 is connected to the front of the protective door body 7, a potential board 2 is connected to the front of the main controller 1, a set of status indicator lights 3 is connected to the front of the potential board 2, an emergency stop switch 4 is embedded in the front of the main controller 1, and the status indicator lights 3 make it easy for staff to understand the operating status of the equipment. A sign 6 is connected to the front of one of the door bodies 11, and an emergency escape window 5 is opened on the front of both door bodies 11. A latch slot 12 is opened on the back of each door body 11. The sign 6 can provide guidance and evacuation for passengers. A lamp holder 8 is connected to the front of the protective door body 7, and a lighting lamp 9 is connected to the front of the lamp holder 8. The lighting lamp 9 can provide lighting for passengers.

[0024] In this embodiment, two sets of electro-hydraulic telescopic rods 22 are connected to a common adapter plate 23 on their adjacent sides. Each of the two adapter plates 23 is connected to a pressure sensor 10 on its adjacent side. The pressure sensor 10 can monitor the closing resistance. The adjacent sides of the two pressure sensors 10 are connected to the door body 11. Each of the two door bodies 11 is connected to a connecting plate 15 on its adjacent side. The connecting plate 15 allows the pressure sensor 10 to be directly connected to the adjacent sides of the door body 11. Each of the two connecting plates 15 is connected to a sensor base 16 on its adjacent side. Each of the two sensor bases 16 is connected to a set of sensor lights 17 on its adjacent side. The warning system formed by the sensor lights 17 and the sensor bases 16 can light up a warning light in time when the door body 11 is about to close.

[0025] Working principle: The subway track safety door uses the door body 7 as the overall frame. When the electric hydraulic telescopic rod 22 extends or retracts, the door body 11 can smoothly slide within the limit groove 18 with the assistance of the moving wheels 20. During daily operation, the main controller 1 acts as the core hub, setting the operating parameters of the electric hydraulic telescopic rod 22 via the potentiometer 2. When the train arrives at the station, the main controller 1 receives the door opening command and controls the electric hydraulic telescopic rod 22 to retract, pushing the adapter plate 23 to drive the door body 11 to slide open to both sides. At this time, the status indicator light 3 lights up green. When the train is about to leave the station, the main controller 1 controls the electric hydraulic telescopic rod 22 to retract. 2. Extend and push the adapter plate 23 to make the door 11 slide towards the middle to close. After closing, the status indicator light 3 turns red. During the closing process, the pressure sensor 10 on the back of the door 11 monitors the resistance in real time. Once abnormal pressure caused by trapping a person or object is detected, the signal is transmitted to the main controller 1. The main controller 1 then controls the electric hydraulic telescopic rod 22 to extend in the opposite direction, so that the door 11 reopens. At the same time, the status indicator light 3 flashes an alarm. In case of emergency, staff or passengers can press the emergency stop switch 4 on the front of the main controller 1 to cut off the power of the electric hydraulic telescopic rod 22 and make the door 11 stop moving immediately.
