Description

Technical Field

[0001] The invention relates to the technical field of subways, in particular to a subway door capable of diverting flow. Background Art

[0002] In most subway stations now, the waiting area for boarding the train is divided into waiting areas on both sides of the disembarkation area. At the same time, there are usually slogans such as "get off first and then get on" written on the ground. However, some passengers ignore the passengers getting off and keep squeezing into the car after the subway arrives at the station and the doors open, which causes congestion at the subway door and reduces the efficiency of getting on and off the train.

[0003] In the face of congestion at the doors, some subway stations will have staff at the doors to maintain order, but the large number of staff required increases labor costs. In addition, some subway stations will place isolation barriers at the station entrance to divert passengers waiting to board the train, but such methods mostly solve the problem of crowded passengers boarding the train, and are less effective for passengers who do not abide by the rules. The situation of "getting on and off at the same time" will still often occur, and there is no guarantee that passengers will get off the train first. Summary of the invention

A fixed plate 17 is provided on the upper end surface of the movable plate 19, and a sliding mechanism is provided between the fixed plate 17 and the movable plate 19, and the sliding mechanism can drive the movable plate 19 to slide. The sliding mechanism includes a slider cavity 32 opened in the fixed plate 17 and symmetrical on both sides, and a sliding motor 39 is fixed in the inner wall of the slider cavity 32 on both sides. The two ends of the sliding motor 39 are symmetrical and powered by a rotating shaft 31, and the rotating shafts 31 on both sides extend to the slider cavities 32 on both sides away from the sliding motor 39. The ends are respectively connected to the sliders 40 threadedly connected, and the end surface of the slider 40 close to the subway door 11 is fixedly connected to the end surface of the movable plate 19 away from the subway door 11. The sliding of the slider 40 can drive the subway door 11 to slide through the movable plate 19, that is, turning on the sliding motor 39 can realize the sliding of the subway doors 11 on both sides toward or away from each other.

[0028] An extension cavity 12 is provided in the subway doors 11 on both sides, and an extension plate 13 is slidably provided in the extension cavity 12. A pressure mechanism is provided at one end of the extension plate 13. When the extension plate 13 slides out of the extension cavity 12, the pressure mechanism can pop out, so as to detect the density of people who need to enter the subway from the outside. A power mechanism is provided in the extension plate 13 and on one side of the pressure mechanism. The power mechanism can drive the extension plate 13 to slide in the extension cavity 12. The power mechanism includes a threaded cavity 14 provided in the extension plate 13. A telescopic motor 15 is fixedly provided near one end of the threaded cavity 14 in the subway door 11. The telescopic motor 15 is close to the extension plate 1 The end surface of the pressure chamber 14 is dynamically connected with a threaded shaft 16, and the outer circumferential surface of the threaded shaft 16 can be threadedly connected with the inner wall of the threaded chamber 14.

Of course, the first contact switch 34 and the second contact switch 35 can also be omitted, and the electromagnet 38 can be controlled to start by other means, such as program time. A base 23 is arranged at the lower side of the subway door 11, and a rack mechanism is arranged between the base 23 and the subway door 11. When the subway door 1 When sliding, the rack mechanism can drive the subway door 11 to rotate outward, so as to limit the number of passengers getting off first and getting on later, and prevent crowding. The rack mechanism includes a rack cavity 22 which is opened in the base 23 and is symmetrical on both sides. A spur gear 21 is slidably arranged in the rack cavity 22. The spur gear 21 is fixedly connected to the subway door 11 at one end face close to the subway door 11. A rack 24 is fixedly arranged on the inner wall of the rack cavity 22 at one side away from the center of the base 23. The outer cylindrical surface of the spur gear 21 can be matched with the rack 24. When the spur gear 21 slides to the rack 24, it can drive the spur gear 21 to rotate through meshing connection, thereby realizing the rotation of the subway door 11.

[0029] The following describes the control method for opening and closing a subway door in this embodiment, which specifically includes the following steps:

[0030] Subway door opening steps: When the subway stops, the sliding motor 39 starts to rotate forward, driving the rotating shafts 31 on both sides to rotate synchronously, and then drives the slider 40 to slide away from the sliding motor 39 through the threaded connection. The slider 40 drives the movable plate 19 to slide through the fixed connection. The movable plate 19 can drive the subway door 11 to slide through the fixed shaft 18. At this time, the subway doors 11 on both sides slide away from the sliding motor 39 until they are opened. Here, the rear of the subway door 11 is directly opposite to the passenger disembarkation area in the subway, and the two sides of the disembarkation area are the waiting areas for passengers getting on the subway. The front of the subway door 11 corresponds to the subway car, and the opening of the pressure chamber 20 faces the disembarkation area. Passengers who need to wait for the ride wait to get on the train in the waiting area, and passengers getting off the train wait to get off in the car.

[0031] Subway door unlocking steps: When the subway door 11 slides, the electromagnet 38 is activated, and the magnet 30 is driven to slide through the magnetic connection, and then the lock block 29 is driven to slide into the cavity 36 through the fixed connection, and is out of contact with the inner wall of the lock cavity 28. At this time, the movable plate 19 is unlocked from the subway door 11. Here, the first contact switch 34 is in contact with the second contact switch 35, but the electromagnet 38 will not stop working, because the electromagnet 38 is forced to start.

[0032] Subway door rotation steps: When the subway door 11 slides, the spur gear 21 is driven to slide through a fixed connection. When the spur gear 21 slides to mesh with the rack 24 and contacts one end face of the rack cavity 22, the outer cylindrical surface of the spur gear 21 is meshed with the gear of one end face of the rack 24. When the spur gear 21 continues to slide, it can drive the spur gear 21 to rotate through the gear meshing. The spur gear 21 drives the subway door 11 to rotate toward the disembarkation area near one end of the sliding motor 39 through a fixed connection until the subway doors 11 on both sides are unfolded in an "eight" shape, and the wide openings of the subway doors on both sides face the carriage, and the narrow openings face the disembarkation area, so that passengers in the subway can get off first. Here, when the subway door 11 slides, it can be driven to slide the spur gear 21 through a fixed connection first. When the spur gear 21 moves to the point where it is about to mesh with the rack 24, the electromagnet 38 is activated to unlock the movable plate 19 and the subway door 11.

[0033] Extension plate opening steps: when the subway door 11 slides, the telescopic motor 15 starts to rotate forward, and the telescopic motor 15 drives the threaded shaft 16 to rotate, and then drives the extension plate 13 to slide in the direction away from the corresponding telescopic motor 15 through the threaded connection, and the first contact switch 34 is separated from the second contact switch 35. When the extension plate 13 slides to the maximum distance, the telescopic motor 15 stops rotating. At this time, the extension plates 13 on both sides will reduce the getting-off area to prevent the passengers who get off the middle from getting off the subway while the passengers waiting on both sides get on the subway at the same time, causing chaos. At the same time, the sliding of the extension plate 13 drives the pressure plate 26 to slide. When the pressure plate 26 slides out of the extension cavity 12, the pressure plate 26 is no longer pressed by the inner wall of the extension cavity 12. At this time, the compression spring 27 drives the pressure plate 26 to slide in the direction away from the distance sensor 25 through its own elasticity, and the distance sensor 25 starts When the extension plate 13 moves to the maximum distance, after a period of time, the telescopic motor 15 reverses and drives the extension plate 13 to reset. After the extension plate 13 is reset, the area between the subway doors 11 on both sides becomes larger. At this time, the crowded subway getting on and off is much relieved when the subway door is opened. The larger area between the subway doors 11 on both sides is convenient for passengers to get on and off the subway at this time, thereby improving efficiency.

[0034] Subway door closing steps: When the subway door 11 is to be closed, the sliding motor 39 reverses, driving the subway door 11 to slide toward the sliding motor 39 and reset. When the spur gear 21 passes the rack 24 again, the spur gear 21 rotates and drives the subway door 11 to rotate to reset. At this time, the first contact switch 34 and the second contact switch 35 are against each other, which can control the electromagnet 38 to stop working. The locking spring 37 drives the lock block 29 to slide into the lock cavity 28 through its own elasticity, and locks the subway door 11 and the movable plate 19. When the slider 40 slides to reset, the adjacent end faces of the subway doors 11 on both sides are against each other to complete the closing.

[0035] Example 2: Please refer to Figure 7 In this embodiment, guide plates 41 are fixed at both ends of the pressure plate 26 near the compression spring 27. The guide plates 41 are slidably connected to the pressure chamber 20 and cover the compression spring 27 therein, so that the pressure plate 26 will not completely extend out of the pressure chamber 20 and cannot be reset normally, and also play a role in guiding and protecting the compression spring 27. The guide plate 41 can be provided with a limit block, and the side wall of the pressure chamber 20 is provided with a limit groove, and the limit block extends into the limit groove.

[0036] The above embodiments are only for illustrating the technical concept and features of the present invention, and their purpose is to enable people familiar with the technology in this field to understand the content of the present invention and implement it, and they cannot be used to limit the protection scope of the present invention. Any equivalent changes or modifications made according to the spirit of the present invention should be included in the protection scope of the present invention.
