[0035] See also Figures 1 to 3 The embodiment of the present application provides a platform lift door 100 and a platform hall 201 having the same. The platform lift door 100 is arranged on the platform 10. The platform 10 can be a platform of a high-speed railway station, a platform of a railway station, or a platform of an intercity train. There is no restriction here and you can choose according to actual conditions.

[0036] Platform 10 includes a transition area 101 adjacent to the train tracks and a waiting area 102 connected to transition area 101 and away from the train tracks. It is understood that transition area 101 is located between waiting area 102 and the train tracks, and waiting area 102 can accommodate passengers. In this embodiment, platform 10 is a high-speed rail station platform. In other embodiments, other platforms can be selected based on actual circumstances and are not limited here. A high-speed train may be parked on the train tracks to allow passengers in waiting area 102 to board the train and / or passengers on the high-speed train to disembark and enter waiting area 102.

[0037] The platform hall 201 of the present application is set up on platform 10. It can utilize the existing area and area of ​​platform 10 and convert the area originally belonging to platform 10 into a waiting area, thereby expanding the total waiting area of ​​the high-speed railway station and improving the convenience and comfort of passengers waiting.

[0038] See also Figures 1 to 3 The platform lifting door 100 includes: a support assembly 21, a door body assembly 22 and a drive assembly 23.

[0039] See also Figures 1 to 3 The support assembly 21 includes support columns 211 erected on the platform 10, and two support columns 211 are arranged at intervals; the material of the support columns 211 can be metal, such as steel sections or welded steel plates, and the support columns 211 are arranged in a vertical direction and close to the transition zone 101.

[0040] See also Figures 1 to 3 The door body assembly 22 includes a first door body 221 and a second door body 222. The first door body 221 is located at the upper end of the supporting column 211, and the two ends of the first door body 221 are respectively connected to the two supporting columns 211, and the two ends of the second door body 222 are respectively slidably connected to the two supporting columns 211; it can be understood that the main material of the first door body 221 and the second door body 222 can be glass, so that external light can enter the waiting area 102, and the first door body 221 is fixed at the upper end of the two supporting columns 211, and the second door body 222 is movably arranged in the vertical direction and can slide back and forth in the vertical direction under the action of external force.

[0041] The driving assembly 23 is used to drive the second door body 222 to slide back and forth along the axial direction of the support column 211;

[0042] See also Figures 2 to 4, wherein the two supporting columns 211, the platform 10 and the first door body 221 together form the entrance and exit 103, which connects the waiting area 102 and the transition area 101. When there is no high-speed train parked on the train track, the drive component 23 drives the second door body 222 to slide downward to close the entrance and exit 103. At this time, passengers can only move in the waiting area 102 and cannot enter the transition area 101. When a high-speed train is parked on the train track, the drive component 23 drives the second door body 222 to slide upward and open the entrance and exit 103, and the first door body 221 and the second door body 222 at least partially overlap. At this time, passengers can enter the waiting area 102 from the transition area 101 through the entrance and exit 103, or enter the transition area 101 from the waiting area 102. The transition area 101 is adjacent to the high-speed railway. Therefore, any passenger in the transition area 101 can enter the high-speed railway through any carriage door of the high-speed railway, or passengers getting off from any carriage door of the high-speed railway can pass through the transition area 101 and enter the waiting area 102 from the entrance and exit 103. There is no need to align the entrance and exit 103 with the carriage door, which can adapt to different types of high-speed railways, thereby improving the applicability of the waiting door of platform 10.

[0043] See also Figures 2 to 4 Optionally, by setting a platform lifting door 100 in the waiting area 102 of the platform 10, the passage between the waiting area 102 and the transition area 101 can be effectively controlled. By the movable setting of the second door body 222, the second door body 222 slides to a structure that partially overlaps with the first door body 221, thereby enhancing the safety and isolation of the platform 10, and allowing passengers to enter the transition area 101 from the entrance and exit 103 and then enter the high-speed rail from any car door. When the second door body 222 closes the entrance and exit 103, it can effectively prevent passengers from mistakenly entering the train track area, thereby improving safety. In addition, the platform lifting door 100 can adapt to different train heights and sizes, thereby increasing the versatility and adaptability of the system.

[0044] See also Figures 2 to 4 In some embodiments, the driving assembly 23 includes a first rack 233, a first gear 232 meshing with the first rack 233, and a driver 231 connected to one of the supporting columns 211 and used to drive the first gear 232 to rotate, and the first rack 233 is arranged at the side edge of the second door body 222.

[0045] See also Figures 2 to 4Alternatively, the driver 231 may be a servo motor. The driver 231 drives the first gear 232 to rotate, thereby driving the rack and sliding the second door body 222. The servo motor changes direction, thereby changing the sliding direction of the second door body 222. For example, forward rotation drives the second door body 222 to close the entrance 103, or reverse rotation drives the second door body 222 to open the entrance 103. The rack and pinion transmission method provides precise and stable control of the second door body 222, ensuring smooth operation of the platform lift door 100, reducing mechanical wear, and increasing service life.

[0046] See also Figures 2 to 4 In some embodiments, the drive assembly 23 also includes a slider 236 connected to the edge of the second door body 222 and a guide rail 237 connected to the support column 211 and arranged axially thereof. The first rack 233 is connected to the slider 236, and the slider 236 slides in conjunction with the guide rail 237.

[0047] Optionally, through the guide rail 237 on the support column 211, the slider 236 is connected to the edge of the second door body 222 and slides with the guide rail 237. The first rack 233 is connected to the slider 236, so that when the first gear 232 drives the first rack 233, the guide rail 237 can guide the slider 236 to slide along the guide rail 237, thereby improving the stability of the up and down movement of the second door body 222, avoiding the shaking and instability of the second door body 222, and improving the operation accuracy and safety of the second door body 222.

[0048] Optionally, two sliders 236 are arranged at intervals. In other embodiments, three or more sliders 236 may be provided. There is no limitation here and the selection can be made according to actual conditions.

[0049] See also Figures 3 to 5 In some embodiments, the driving assembly 23 further includes a connecting belt 234 and a counterweight 240 slidably connected to one of the support columns 211. The counterweight 240 and the driver 231 are connected to the same support column 211. The two ends of the connecting belt 234 are respectively connected to the counterweight 240 and the second door body 222, and the counterweight 240 and the second door body 222 slide synchronously and in opposite directions.

[0050] See also Figures 3 to 5Optionally, by adding a counterweight 240 and a connecting belt 234, the counterweight 240 and the driver 231 are connected to the same support column 211, and are connected to the second door body 222 through the connecting belt 234. The sliding direction of the counterweight 240 is opposite to the moving direction of the second door body 222. When the second door body 222 descends, the counterweight 240 rises, and the gravitational potential energy of the second door body 222 is transferred to the counterweight 240; when the second door body 222 rises, the counterweight 240 descends, and the gravitational potential energy of the counterweight 240 is transferred to the second door body 222, which plays a balancing role, reduces the load on the driver 231, can effectively reduce the energy consumption of the driver 231, and at the same time reduces the wear of the system, thereby improving the durability and reliability of the system.

[0051] See also Figures 3 to 5 Optionally, the connecting belt 234 is made of rubber, such as a rubber belt, or metal, such as a steel wire rope. A fixing seat 239 is provided on the side of the second door body 222, and the slider 236 is connected to the fixing seat 239. One end of the connecting belt 234 is also connected to the fixing seat 239.

[0052] In some embodiments, the weight of the counterweight 240 is greater than the weight of the second door 222 .

[0053] Optionally, by setting the weight of the counterweight 240 to be greater than the weight of the second door body 222, the counterweight 240 can more effectively balance the weight of the door body, further reducing the workload of the driver 231 and extending the service life of the drive assembly 23. In addition, if an accident occurs to the driver 231, such as a power outage, the driver 231 unlocks the control of the second gear 243, the counterweight 240 descends, and the second door body 222 ascends, and the entrance 103 is opened.

[0054] See also Figures 3 to 5 In some embodiments, a first receiving groove 2111 and a second receiving groove 2112 are respectively provided on two opposite surfaces of the support column 211, the driver 231 is located in the first receiving groove 2111, and the counterweight block 240 is slidably set in the second receiving groove 2112.

[0055] See also Figures 3 to 5Optionally, the support column 211 can be made of H-shaped steel with an H-shaped cross-section. The first receiving groove 2111 and the second receiving groove 2112 are arranged opposite each other. An angle steel 238 can also be arranged in the first receiving groove 2111, and the driver 231 is fixed to the angle steel 238. The counterweight 240 is provided with a rolling bearing 241 for guiding the sliding of the counterweight 240. The rolling bearings 241 are provided on the corresponding surfaces of the counterweight 240 relative to the side walls of the second receiving groove 2112 and the bottom of the second receiving groove 2112, thereby improving the convenience and smoothness of the sliding of the counterweight 240 in the second receiving groove 2112 and ensuring the smooth operation of the counterweight 240. The H-shaped steel also improves the compactness of the overall structure and reduces the sliding resistance of the counterweight 240 through the rolling bearings 241, further improving the operating efficiency of the system.

[0056] See also Figures 3 to 5 In some embodiments, the first accommodating groove 2111 and the second accommodating groove 2112 are provided with a connecting port 2351 at one end of the supporting column 211, and a guide wheel 235 is rotatably provided at the position of the connecting port 2351, and the connecting belt 234 passes through the connecting port 2351 and wraps around the guide wheel 235.

[0057] See also Figures 3 to 5 Optionally, when the support column 211 is set vertically, the connecting port 2351 is located at the top of the support column 211, and the guide wheel 235 is rotated at the connecting port 2351 through the rotating shaft, and the guide wheel 235 passes through the connecting port 2351, so that the guide wheel 235 is partially located in the first accommodation groove and at least partially located in the second accommodation groove 2112, and the connecting belt 234 passes through the connecting port 2351 and wraps around the guide wheel 235, thereby changing the movement direction of the connecting belt 234, so as to optimize the sliding path of the counterweight block 240 and the second door body 222, reduce the wear of the connecting belt 234, and enable the counterweight block 240 and the second door body 222 to achieve synchronous and reverse sliding, while improving the reliability of the system.

[0058] In some embodiments, two driving assemblies 23 are provided, and the two driving assemblies 23 are respectively connected to the two supporting columns 211 .

[0059] See also Figures 3 to 5Optionally, two drive assemblies 23 are provided on the platform lift door 100, each connected to the two support columns 211. This dual-drive arrangement improves the operational stability of the second door body 222, ensuring that the second door body 222 can smoothly open or close the entrance and exit 103 under any circumstances. It is understood that in this embodiment, two counterweights 240 are provided, and the total weight of the two counterweights 240 is slightly greater than the weight of the second door body 222. Thus, the two counterweights 240 can pull the second door body 222 upward by their own gravity, so that in unexpected circumstances such as power outages, the second door body 222 can open the entrance and exit 103, thereby preventing accidents.

[0060] Optionally, the servo motor is provided with a common electromagnetic brake accessory, which can lock the door at any stop position when powered on to prevent passengers from pushing the door by themselves, and release the electromagnetic brake when powered off, so that the second door 222 can be pushed freely by passengers.

[0061] See also Figures 5 to 7 In some embodiments, the door body assembly 22 also includes a third door body 223, and the two ends of the third door body 223 are respectively slidably connected to the two support columns 211. The driving assembly 23 also includes a second rack 242 connected to the edge of the third door body 223 and a second gear 243 engaged with the second rack 242. The first gear 232 and the second gear 243 are coaxially arranged, and the radius of the second gear 243 is twice the radius of the first gear 232. The length of the second rack 242 is twice the length of the first rack 233. The connecting belt 234 connects the second door body 222 or the third door body 223.

[0062] It is understandable that a guide rail 237 and a slider 236 may also be provided on the third door body 223 to guide the third door body 223 to slide smoothly.

[0063] See also Figures 5 to 7 Optionally, the height of the second door body 222 is the same as that of the third door body 223, and the structure is basically the same, which facilitates mass production. And for the entrance and exit 103 at the same height, the size of the second door body 222 and the third door body 223 can be reduced by closing or opening the second door body 222 and the third door body 223, and the small-sized door body is easy to process. By adding the third door body 223, the two ends of the third door body 223 are respectively slidably connected to the support column 211, and driven by the second rack 242 and the second gear 243. The radius of the second gear 243 is twice the radius of the first gear 232, ensuring that the second door body 222 and the third door body 223 can rise to the extreme position at the same time and overlap with the first door body 221, or fall to the limit at the same time and close the entrance and exit 103 together.

[0064] Optionally, the platform lift door 100 further includes a laser beam emitter, which comprises a transmitter and a receiver. The transmitter and receiver are located on two support columns 211, respectively, and form a sensing light curtain at the entrance and exit 103. The sensing light curtain can sense whether there are any passengers stranded at the entrance and exit 103. The transmitter and receiver can be infrared transmitters and infrared receivers, respectively. The infrared transmitter transmits infrared light to the infrared receiver, and the infrared receiver receives infrared light from the infrared transmitter. The transmitter can also be a transmitter that transmits visible light to the receiver, and the receiver receives visible light from the transmitter. This is not a limitation and can be selected based on actual circumstances.

[0065] See also Figures 5 to 8 In one embodiment, the platform lift door 100 further includes a detection sensor mounted on the support column 211. When the detection sensor detects that the high-speed train has not stopped, it indicates that the train is passing through the station and is ignored. When the detection sensor detects that the high-speed train has entered the station and stopped at the platform 10, it waits for 5 seconds before the laser beam is turned on, forming a parallel light curtain in front of the second door body 222. If a passenger in the waiting area 102 gets too close to the second door body 222, the sensor light curtain will be blocked. At this time, the controller will control the voice alarm to issue a voice warning, reminding passengers that the second door body 222 is about to open and to keep a distance from the second door body 222 until no one approaches the second door body 222.

[0066] See also Figures 5 to 8 When the sensing light curtain confirms that no one is staying near the second door body 222 and the sensing light curtain has fully achieved shooting, the light curtain is closed, the driver 231 is started, and drives the first gear 232 and the second gear 243 to rotate, the first gear 232 and the second gear 243 respectively drive the first rack 233 and the second rack 242 to slide, and make the second door body 222 and the third door body 223 synchronously lift upward along the linear guide rail 237 installed on the support column 211, and both overlap with the first door body 221, so that the second door body 222 and the third door body 223 open the entrance and exit 103.

[0067] See also Figures 5 to 8After the waiting area 102 and the train exchange passengers, the train's car doors close. The detection sensors on the track side detect that the train doors have closed. After waiting for 3 seconds, the laser beam emitters activate the light curtain again. When the detection sensors detect that there are passengers stranded in the transition area 101, a voice prompt is given to urge passengers to enter the waiting area 102 from entrance 103 as soon as possible, and a reminder is given that entrance 103 is about to close.
