Description

Technical Field

[0001] This utility model relates to the field of subway platform gap treatment technology, and in particular to a device for handling the gap between subway trains and platforms. Background Technology

[0002] The gaps between subway platforms and trains cause considerable inconvenience for passengers getting on and off. During peak hours, when passengers rush in and out, the heels of high heels and children's soft-soled shoes can easily get stuck in the gaps, which can range from disrupting the flow of passengers to causing ankle sprains. Wheelchair wheels and luggage wheels also frequently get stuck in the gaps, adding to the trouble for passengers with mobility impairments and those carrying luggage.

[0003] The current approach only reduces the size of the gap, but the gap still exists. The risk of materials falling or shoes getting stuck when passengers get on and off the vehicle remains, and the overall safety needs to be improved. Utility Model Content

[0004] The purpose of this utility model is to provide a device for handling gaps between subway trains and platforms that can effectively seal gaps, ensuring high safety without affecting subway operation. It can be flexibly and conveniently installed on existing platforms.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A device for handling the gap between a subway train and a platform includes a mounting plate base. A baffle is hinged to the upper edge of the mounting plate base. Two rotating connectors are provided on the outer surface of the mounting plate base and the lower surface of the baffle. A hydraulic cylinder is installed between the two rotating connectors at corresponding positions. A communicating vessel, a mounting seat, and an electric telescopic rod are installed on the outer surface of the mounting plate base. A liquid storage cylinder is fixedly installed in the mounting position of the mounting seat. A piston block is provided inside the liquid storage cylinder, and a piston rod is fixedly connected to the end face of the piston block. The telescopic end of the electric telescopic rod is connected to the end of the piston rod.

[0007] By adopting the above technical solution, the barrier can be flipped up when the subway arrives at the station to seal the gap, and the barrier can be flipped down when the subway leaves the station.

[0008] Furthermore, the communicating vessel is internally connected to the hydraulic cylinder via an oil guide hose, and the reservoir is internally connected to the communicating vessel via a liquid guide pipe. The reservoir contains hydraulic oil.

[0009] By adopting the above technical solution, the effective flow of hydraulic oil is ensured, and the hydraulic cylinder can be effectively driven to extend and retract.

[0010] Furthermore, the outermost end of the baffle is configured as an arc structure with a semi-circular cross-section.

[0011] By adopting the above technical solution, damage to the side of the subway was avoided by the baffle.

[0012] Furthermore, an electrical box is installed on the outer surface of the mounting plate, and a PLC, a motor driver, an intermediate relay, and wiring terminals are installed inside the electrical box. The PLC is electrically connected to the intermediate relay, the intermediate relay is electrically connected to the motor driver, and the motor driver is electrically connected to the electric telescopic rod.

[0013] By adopting the above technical solutions, automatic control operation can be achieved.

[0014] Furthermore, a first proximity switch is installed on the outer surface of the mounting plate, and a second proximity switch is provided on the outside of the mounting plate. The second proximity switch is installed on the top of the protective gate frame by a bracket. Both the first proximity switch and the second proximity switch are electrically connected to the PLC.

[0015] By adopting the above technical solution, the arrival of the subway can be detected by the first proximity switch, and the closure of the external safety gate can be detected by the second proximity switch.

[0016] Furthermore, a linkage plate is provided at the connection between the electric telescopic rod and the piston rod, and two opposite limit switches are installed on the outer surface of the mounting plate base, with the two limit switches distributed on both sides of the linkage plate. The limit switches are electrically connected to the PLC.

[0017] By adopting the above technical solution, the stroke of the electric telescopic pole can be controlled using limit switches.

[0018] In summary, the beneficial technical effects of this utility model are as follows:

[0019] 1. This utility model is installed on the side wall of the platform and located at the gate. When the subway stops at the platform, the electric telescopic rod extends, which drives the piston rod to move axially. This causes the piston block to move inside the liquid storage cylinder. The piston block presses the hydraulic oil inside the liquid storage cylinder into the communicating vessel through the liquid guide pipe, and then into the two hydraulic cylinders through the oil guide hose. The two hydraulic cylinders extend, and under the linkage of the rotating connecting parts, the baffle flips. At this time, the baffle can effectively seal the gap between the subway and the platform, preventing items from falling into the gap between the platform and the subway when passengers get on and off the train, thus effectively improving safety. When the gate closes, the electric telescopic rod retracts, which causes the piston block to move in the opposite position, thereby drawing hydraulic oil from the two hydraulic cylinders. This effectively retracts the hydraulic cylinders, causing the baffle to flip and reset, ensuring that the side of the subway will not be scratched when the subway is running.

[0020] 2. In use, this utility model utilizes a first proximity switch to detect the approach of the subway, then transmits the signal to the PLC. The PLC sends a signal to the intermediate relay, which energizes the motor driver. The motor driver controls the extension of the electric telescopic rod. At this time, the PLC's internal interlock circuit prevents the PLC from responding to the signal sent by the first proximity switch and instead receives the signal from the second proximity switch. After passengers have boarded or alighted, the external safety gate closes first. The second proximity switch, installed on the top of the gate frame, effectively detects the approach of the gate. At this time, the second proximity switch sends a signal to the PLC, which sends a reset command to the intermediate relay. The intermediate relay switches its internal coil circuit, thereby causing the motor driver to control the retraction of the electric telescopic rod. This resets the barrier. The entire control process can be automatically controlled and adjusted according to the actual arrival and departure of the subway, making it highly practical and automated.

[0024] The method of this utility model will be further described in detail below with reference to the accompanying drawings.

[0025] Reference Figure 1 , Figure 2A device for handling the gap between a subway train and a platform includes a mounting plate 1. A baffle 2 is hinged to the upper edge of the mounting plate 1. Two rotating connectors 4 are provided on the outer surface of the mounting plate 1 and the lower surface of the baffle 2. A hydraulic cylinder 3 is installed between the two rotating connectors 4 at corresponding positions. A communicating vessel 5, a mounting base 7, and an electric telescopic rod 12 are installed on the outer surface of the mounting plate 1. A liquid storage cylinder 8 is fixedly installed in the mounting position of the mounting base 7. A piston block is provided inside the liquid storage cylinder 8, and a piston rod 10 is fixedly connected to the end face of the piston block. The telescopic end of the electric telescopic rod 12 is connected to the end of the piston rod 10. The communicating vessel 5 and the hydraulic cylinder 3 are internally connected through an oil guide hose 6. The liquid storage cylinder 8 and the communicating vessel 5 are internally connected through a liquid guide pipe 9. The liquid storage cylinder 8 stores hydraulic oil. The outermost end of the baffle 2 is set as an arc structure with a semi-circular cross-section, which can be easily installed during use. On the side wall of the platform, located at the gate, when the subway stops at the platform, the electric telescopic rod 12 extends. The electric telescopic rod 12 drives the piston rod 10 to move axially, which in turn drives the piston block to move inside the liquid storage tank 8. The piston block pushes the hydraulic oil inside the liquid storage tank 8 into the communicating vessel 5 through the liquid guide pipe 9, and then into the two hydraulic cylinders 3 through the oil guide hose 6. The two hydraulic cylinders 3 extend, and under the linkage of the rotating connecting parts, the baffle 2 flips. At this time, the baffle 2 can effectively seal the gap between the subway and the platform, preventing items from falling into the gap between the platform and the subway when passengers get on and off the train, thus effectively improving safety. When the gate closes, the electric telescopic rod 12 retracts, which causes the piston block to move in the opposite position, thereby extracting the hydraulic oil inside the two hydraulic cylinders 3. This effectively retracts the hydraulic cylinders 3, causing the baffle 2 to flip and reset, ensuring that the side of the subway will not be scratched when the subway is running.

[0026] Reference Figure 1An electrical box 16 is mounted on the outer surface of the mounting base 1. Inside the electrical box 16 are a PLC 17, a motor driver 18, an intermediate relay 19, and terminal blocks 20. The PLC 17 is electrically connected to the intermediate relay 19, which in turn is electrically connected to the motor driver 18. The motor driver 18 is electrically connected to the electric telescopic rod 12. A first proximity switch 14 is mounted on the outer surface of the mounting base 1, and a second proximity switch 15 is installed outside the mounting base 1. The second proximity switch 15 is mounted on the top of the protective gate frame via a bracket. Both the first and second proximity switches 14 are electrically connected to the PLC 17. A linkage plate 11 is installed at the connection between the electric telescopic rod 12 and the piston rod 10. Two opposite limit switches 13 are mounted on the outer surface of the mounting base 1, distributed on both sides of the linkage plate 11. The limit switches 13 are electrically connected to the PLC 17. In use, the first proximity switch 14 can be used to detect subway... The signal is transmitted to the PLC17, which then sends a signal to the intermediate relay 19. The intermediate relay 19 energizes the motor driver 18, which in turn controls the electric telescopic rod 12 to extend. At this time, the interlock circuit inside the PLC17 prevents it from responding to the signal sent by the first proximity switch 14 and instead receives the signal from the second proximity switch 15. After passengers have boarded or alighted, the external safety gate closes first. The second proximity switch 15, installed on the top of the gate frame, effectively detects the approach of the gate and sends a signal to the PLC17. The PLC17 then sends a reset command to the intermediate relay 19, which switches its internal coil circuit, causing the motor driver 18 to retract the electric telescopic rod 12. This resets the baffle 2. The entire control process can be automatically adjusted according to the actual arrival and departure of the subway, making it highly practical and automated.

[0027] Working principle: In use, the device is first installed on the side wall of the platform. The first proximity switch 14 detects the approach of the subway and transmits the signal to the PLC 17. The PLC 17 sends a signal to the intermediate relay 19, which energizes the motor driver 18. The motor driver 18 controls the extension of the electric telescopic rod 12, which drives the piston rod 10 axially. This, in turn, moves the piston block inside the reservoir 8. The piston block forces the hydraulic oil inside the reservoir 8 through the guide pipe 9 into the communicating vessel 5, and then through the guide hose 6 into the two hydraulic cylinders 3. The two hydraulic cylinders 3 extend, and under the linkage of the rotating connector, the baffle 2 flips. At this time, the baffle 2 effectively seals the gap between the subway and the platform, preventing items from falling onto the platform and ground when passengers board and alight. Within the gaps between the metal sections, safety is effectively improved. At this time, the interlock circuit inside PLC17 prevents PLC17 from responding to the signal sent by the first proximity switch 14 and instead receives the signal from the second proximity switch 15. After passengers have finished boarding and alighting, the external safety gate will close first. The second proximity switch 15, installed on the top of the door frame, can effectively detect the approach of the gate. At this time, the second proximity switch 15 sends a signal to PLC17, and PLC17 sends a reset command to the intermediate relay 19. The intermediate relay 19 switches its internal coil circuit, which in turn causes the motor driver 18 to control the electric telescopic rod 12 to retract, thereby causing the piston block to move in the opposite position. This allows the hydraulic oil inside the two hydraulic cylinders 3 to be drawn, effectively retracting the hydraulic cylinders 3 and causing the baffle 2 to flip and reset, ensuring that the side of the subway will not be scratched when the subway is in motion.
