[0046] As described in the background, at present, the platform door is an important facility to ensure the safety of passengers waiting for trains, and is crucial for realizing the bus operation of high-speed railway stations, improving train operation efficiency and waiting service quality, and is also a key factor for realizing multi-network integration. In the related art, the platform door includes two spaced apart support columns, a door body arranged between the two support columns, and a driving assembly. The two support columns are both vertically arranged on the platform, and the door body can slide on the support columns in the vertical direction. The driving assembly includes a driving motor and a rack. The driving motor is fixedly installed on the support column, and the output shaft of the driving motor is fixedly sleeved with a gear. The rack is fixedly installed on the door body in the vertical direction, and the door body slides on the support column through the meshing gear and rack. In order to normally use the above-mentioned platform door, the gear and the rack need to be kept in engagement when the platform door is assembled, and at this time, the door body and the support column need to keep a precise fit relationship, so that the door body can slide on the support column. However, the above-mentioned fitting mode makes the assembly of the platform door very cumbersome, greatly reducing the assembly efficiency.

[0047] Reference Figures 1 to 3 In order to solve the above-mentioned problems, according to one aspect of the present application, the embodiment of the present application provides a platform lifting door, which is arranged on a platform 100. The platform 100 has a transition area 110 adjacent to a train track and a waiting area 120 arranged away from the train track and connected to the transition area 110. The platform lifting door includes a support part 200, a door body 300 and a driving part 400. The support part 200 includes two support columns 210 spaced apart and arranged in the waiting area 120, and a reinforcing member 220 arranged between the two support columns 210. The two ends of the reinforcing member 220 are respectively connected to the two support columns 210. The door body 300 is slidingly installed between the two support columns 210 and can slide up and down in a predetermined direction. The driving part 400 is arranged on the support column 210. The driving part 400 is drivingly connected to the door body 300 and is used to drive the door body 300 to slide up and down in the predetermined direction.

[0048] In the embodiment of the present application, the platform 100 is a platform 100 of a high-speed railway station. In other embodiments, the platform 100 can also be a platform 100 of a common train station, which can be selected according to actual conditions, and is not limited here. The transition area 110 is located between the waiting area 120 and the train track. The waiting area 120 can be used for passengers to stay.

[0049] The two support columns 210, the platform 100 and the door body 300 jointly form an entrance 130, which is connected to the waiting area 120 and the transition area 110; the driving part 400 drives the door body 300 to slide downward to close the entrance 130, and drives the door body 300 to slide upward to open the entrance 130. At the same time, a high-speed train can be parked on the train track, so that passengers in the waiting area 120 can get on the train through the entrance 130, and passengers on the train can get off the train and enter the waiting area 120 through the entrance 130.

[0050] The material of the support column 210 can be metal, such as cast iron or metal steel, and the support column 210 is arranged in a vertical manner and is arranged close to the transition area 110. The reinforcing member 220 can be a reinforcing rod or a reinforcing frame, and the two ends of the reinforcing member 220 are fixedly connected to the two support columns 210, respectively. The main material of the door body 300 can be glass, so that external light can enter the waiting area 120; the preset direction is parallel to the vertical direction, and in other embodiments, the preset direction can also have an included angle greater than 0° and less than 90° with the vertical direction. The driving part 400 can be a screw rod assembly, a synchronous belt assembly, or a cylinder assembly.

[0051] In the present application, since the driving part 400 is arranged on the support column 210, the cooperation relationship between the door body 300 and the support column 210 is no longer limited by the driving part 400; when assembling the platform sliding door, only the driving part 400 arranged on the support column 210 needs to ensure that the door body 300 can smoothly slide up and down along the preset direction, without the need to maintain a precise cooperation relationship between the door body 300 and the support column 210. This structural design not only simplifies the assembly process, but also makes it more convenient and fast to assemble the platform sliding door, saving assembly time; at the same time, it also makes the sliding of the door body 300 only affected by the driving part 400, so that the sliding of the door body 300 becomes more smooth and stable, providing a safer and more convenient travel environment for passengers and improving the passenger's riding experience. In addition, the reinforcing member 220 arranged strengthens the structural strength and stability of the support part 200, which not only helps to improve the stability of the platform sliding door, but also helps to prolong the service life of the platform sliding door.

[0052] Referring to Figure 3 In one embodiment, the reinforcing member 220 includes at least two first reinforcing rods 221 arranged at intervals, and the two ends of the first reinforcing rod 221 are connected to the two support columns 210, respectively.

[0053] In the embodiment, the number of the first reinforcing rods 221 is two, both of which are arranged horizontally and are spaced apart in the vertical direction; meanwhile, both ends of the first reinforcing rods 221 are fixedly connected with the two support columns 210. In other embodiments, the first reinforcing rods 221 can also be replaced by reinforcing frames and are arranged non-horizontally, which can be selected according to actual conditions, and are not limited here. The first reinforcing rods 221 arranged strengthen the structural strength and stability of the support part 200.

[0054] With reference to Figure 2 and Figure 3 In an embodiment, the lower first reinforcing rod 221 of the plurality of first reinforcing rods 221 is connected with the surface of the support column 210 close to the waiting area 120.

[0055] In the embodiment, the lower first reinforcing rod 221 of the two first reinforcing rods 221 is fixedly connected with the surface of the support column 210 close to the waiting area 120, and the upper first reinforcing rod 221 of the two first reinforcing rods 221 is fixedly connected with the top end of the support column 210. The above structure design avoids the interference of the first reinforcing rod 221 to the sliding door body 300, and ensures the smooth operation of the door body 300 sliding operation.

[0056] With reference to Figure 3 In an embodiment, the number of the first reinforcing rods 221 is two, and a mounting space 223 is formed between the two first reinforcing rods 221; the reinforcing member 220 further comprises at least one second reinforcing rod 222, the second reinforcing rod 222 is located in the mounting space 223, and both ends of the second reinforcing rod 222 are connected with the two first reinforcing rods 221, respectively.

[0057] In the embodiment, the number of the second reinforcing rods 222 is two, both of which are arranged in the vertical direction and are spaced apart in the horizontal direction; meanwhile, both ends of the second reinforcing rods 222 are fixedly connected with the two first reinforcing rods 221. In other embodiments, the number of the second reinforcing rods 222 can also be one, three or other numbers, and the second reinforcing rods 222 can also be arranged non-vertically, which can be selected according to actual conditions, and are not limited here. The second reinforcing rods 222 arranged further strengthen the structural strength and stability of the support part 200; meanwhile, the second reinforcing rods 222 arranged in the mounting space 223 help to reduce the overall volume of the platform sliding door.

[0058] With reference to Figure 3 and Figure 10In an embodiment, at least one of the controller 600, the strong current wire, the weak current wire and the signal wire is arranged in the mounting space 223; the mounting space 223 has two oppositely arranged mounting openings, and the support part further comprises two oppositely arranged protective baffle plates which respectively seal the two mounting openings.

[0059] In the embodiment, the controller 600, the strong current wire, the weak current wire and the signal wire are all arranged in the mounting space 223; the direction from one mounting opening to the other mounting opening is perpendicular to the preset direction and is also perpendicular to the direction from one support column 210 to another support column 210. The protective baffle plates are fixedly arranged on the two first reinforcing rods 221 and are also fixedly arranged on the two support columns 210; in addition, the protective baffle plates completely seal the corresponding mounting openings. The arranged mounting space 223 plays a role of mounting and accommodating components, which helps to reduce the volume of the platform lift door; in cooperation with the protective baffle plates, the mounting space 223 can effectively protect the components arranged in the mounting space 223 and can also improve the overall aesthetic appearance of the platform lift door. In addition, the lamp strip is fixedly arranged on the lower first reinforcing rod 221.

[0060] Referring to Figures 1 to 3 In an embodiment, the platform 100 is provided with a downwardly extending mounting hole, and the lower end of the support column 210 is fixedly arranged in the mounting hole, so as to enhance the stability of the support column 210 arranged on the platform 100.

[0061] Referring to Figures 1 to 3 In an embodiment, the platform 100 has a ceiling, and the upper end of the support column 210 is fixedly connected with the ceiling, so as to enhance the stability of the support column 210 arranged on the platform 100.

[0062] Referring to Figure 1 , Figure 2 and Figure 4 In an embodiment, the driving part 400 comprises a driving member 410 and a transmission member 420, and the driving member 410 is drivingly connected with the transmission member 420; the transmission member 420 is drivingly connected with the door body 300, and is used to drive the door body 300 to slide up and down along the preset direction.

[0063] In the embodiment, the driving member 410 is a servo motor which is fixedly arranged on the support column 210; the servo motor changes the turning direction, so as to change the sliding direction of the door body 300, such as forward rotation to drive the door body 300 to close the entrance and exit 130 or reverse rotation to drive the door body 300 to open the entrance and exit 130. In other embodiments, the driving member 410 can also be a servo motor. The transmission member 420 can be a chain, and the chain is fixedly connected with the door body 300, while the driving member 410 is drivingly connected with the chain, so as to drive the chain and the door body 300 to reciprocally slide along the vertical direction.

[0064] The driving member 410 and the transmission member 420 used in cooperation not only enable the door body 300 to smoothly slide reciprocally on the support column 210, but also facilitate the separate maintenance and replacement of the driving member 410 and the transmission member 420, effectively reducing the maintenance and replacement costs.

[0065] In addition, the servo motor is provided with a common electromagnetic brake accessory, which can be braked and locked at any door stopping position in the power-on state to avoid passengers manually pushing the door body 300; and the electromagnetic brake is released in the power-off state, so that the door body 300 can be freely pushed by passengers.

[0066] With reference to Figure 1 and Figure 5 In an embodiment, the driving part 400 further comprises a sliding block 310 connected to the edge of the door body 300 and a guide rail 211 connected to the support column 210 and arranged in a preset direction, and the door body 300 slides on the support column 210 through the sliding cooperation of the sliding block 310 and the guide rail 211.

[0067] In the embodiment, the sliding block 310 is fixedly installed on the edge of the door body 300, and the guide rail 211 is fixedly installed on the support column 210. The guide rail 211 arranged can guide the sliding block 310 to slide along the guide rail 211, thereby guiding the door body 300 to slide along the guide rail 211, which not only improves the stability of the reciprocating sliding of the door body 300 and avoids the shaking and instability of the door body 300, but also improves the operation precision and safety of the door body 300.

[0068] In addition, the sliding block 310 can also be arranged at intervals in a preset direction, and in other embodiments, three or more than three can also be arranged, which is not limited here and can be selected according to actual conditions.

[0069] With reference to Figure 1 and Figure 4 In the first embodiment, the transmission member 420 is a synchronous belt, and the synchronous belt is rotatably installed on the support column 210; the driving member 410 has a driving wheel, and the driving wheel drives the synchronous belt to rotate through meshing cooperation with the synchronous belt.

[0070] In the embodiment, a rolling bearing is installed on the support column 210, a pulley is fixedly sleeved on the rolling bearing, the pulley is penetrated into the synchronous belt and remains in meshing with the synchronous belt, so that the synchronous belt is rotatably installed on the support column 210. An installation table 212 is fixedly installed on the support column 210, the driving member 410 is fixedly installed on the installation table 212 and located on the side of the synchronous belt away from the support column 210; the structure of the driving wheel is basically the same as that of the pulley, and the driving wheel is drivingly connected with the output end of the driving member 410.

[0071] On one hand, the transmission member 420 and the driving member 410 used in cooperation can ensure that the door body 300 moves at a preset position and speed, so that the door body 300 realizes high-precision motion control and improves the safety of the platform lifting door. On the other hand, when the driving wheel drives the synchronous belt to rotate, the synchronous belt can smoothly drive the door body 300 to slide up and down, and does not have the shaking or jumping phenomenon that may occur due to chain link loosening as in chain transmission. Moreover, the synchronous belt itself has a certain elasticity and can buffer external impact force to a certain extent, so that the door body 300 can still maintain a relatively stable running state when subjected to external force interference (such as accidental collision by a passenger).

[0072] With reference to Figure 1 and Figure 4 In the first embodiment, the platform lifting door further comprises a counterweight part 500, both ends of the synchronous belt are connected to the counterweight part 500 and the door body 300 respectively, and the counterweight part 500 slides synchronously with the door body 300 and in the opposite direction.

[0073] In the present embodiment, the counterweight part 500 is fixedly connected to the synchronous belt. The sliding direction of the counterweight part 500 is opposite to the moving direction of the door body 300; specifically, when the door body 300 descends, the counterweight part 500 ascends, and the gravitational potential energy of the door body 300 is transferred to the counterweight part 500; when the door body 300 ascends, the counterweight part 500 descends, and the gravitational potential energy of the counterweight part 500 is transferred to the door body 300. The counterweight part 500 provided plays a balancing role, not only effectively reducing the load of the driving member 410, thereby effectively reducing the energy consumption of the driving member 410, but also reducing the wear of the platform lifting door and improving the durability and reliability of the platform lifting door.

[0074] With reference to Figure 6 and Figure 7 In the second embodiment, the transmission member 420 further comprises a lead screw 421 and a nut block 422, wherein the lead screw 421 is rotationally installed on the support column 210, and the driving member 410 drives the lead screw 421 to rotate through a driving connection belt 423; the nut block 422 is threadedly sleeved on the lead screw 421 and is used to drive the door body 300 to slide up and down along a preset direction.

[0075] In the present embodiment, the lead screw 421 is arranged along a preset direction and is rotationally installed on the support column 210; the nut block 422 is sleeved on the lead screw 421 and threadedly cooperates with the lead screw 421 to slide on the lead screw 421 along the preset direction; at the same time, the nut block 422 drives the door body 300 to reciprocally slide along the preset direction through direct or indirect connection with the door body 300.

[0076] With reference to Figure 6In a specific embodiment of the second embodiment, the transmission member 420 further comprises a connecting belt 423 rotatably mounted on the support column 210; the door body 300 is connected with the nut block 422; the platform 100 further comprises a counterweight 500, and the two ends of the connecting belt 423 are connected with the counterweight 500 and the nut block 422 respectively, and the counterweight 500 and the nut block 422 slide synchronously and in opposite directions.

[0077] In the embodiment, the nut block 422 is directly connected with the door body 300; specifically, a guide wheel is rotatably mounted on the support column 210, and the connecting belt 423 is sleeved on the guide wheel and rotates on the support column 210 by contacting the guide wheel.

[0092] Referring to Figure 1 and Figure 4In an embodiment, two driving parts 400 are provided, and the two driving parts 400 are respectively arranged on the two support columns 210. The above-mentioned double driving design improves the stability of the operation of the door body 300, and ensures that the door body 300 can smoothly open or close the doorway 130 in any case. It can be understood that the counterweight part 500 includes two counterweight blocks 510, and the two counterweight blocks 510 are respectively arranged in one-to-one correspondence with the two groups of driving parts 400, and the weights of the two counterweight blocks 510 remain the same.

[0093] With reference to Figure 1 , Figure 4 and Figures 6 to 10 In an embodiment, the platform lifting door further comprises a controller 600 and a laser emitter-receiver 610 electrically connected with the controller 600, and the controller 600 is electrically connected with the driving part 410; the laser emitter-receiver 610 comprises an infrared emitter 611 and an infrared receiver 612, and the infrared emitter 611 and the infrared receiver 612 are respectively arranged on the two support columns 210 and form an induction light curtain at the doorway 130, which can sense whether there is a passenger staying at the doorway 130.

[0094] With reference to Figure 1 , Figure 2 and Figures 4 to 10 In an embodiment, the platform lifting door further comprises a detection sensor 620 arranged on the support column 210 and electrically connected with the controller 600, and when the detection sensor 620 detects that the high-speed train enters the station and stops at the platform 100, the laser emitter-receiver 610 on the side of the platform 100 facing away from the transition area 110 is turned on to form a parallel light curtain in front of the door body 300. If the passenger in the waiting area 120 is too close to the door body 300, the induction light curtain will be blocked, and at this time the controller 600 controls the voice alarm 630 electrically connected with the controller 600 to issue a voice warning to remind the passenger that the door body 300 is about to open, and please keep a distance from the door body 300.

[0095] When the induction light curtain confirms that there is no person staying near the door body 300, and the induction light curtain is all realized to be shot, the light curtain is closed, the driving part 410 is started, and drives the driving wheel to rotate, the driving wheel drives the synchronous belt to rotate on the support column 210, so that the door body 300 is lifted upwards along the preset direction, thereby opening the doorway 130.

[0096] After the passengers in the waiting area 120 and the train have finished boarding, the train compartment door is closed, the track-side detection sensor 620 detects that the train door has been closed, the laser beam barrier 610 is turned on again, and when the detection sensor 620 detects that there are passengers remaining in the transition area 110, the passengers are prompted by voice to enter the waiting area 120 from the entrance 130 as soon as possible, and the voice prompts that the entrance 130 will be closed soon. When the detection sensor 620 detects that there are no passengers remaining in the transition area 110, and the induction light curtain senses that there are no passengers remaining at the entrance 130, the voice prompts that the entrance 130 will be closed soon. At this time, the driving part 410 is reversed, and the door body 300 is lowered with the assistance of the counterweight part 500. After the door body 300 is closed in place, the induction light curtain is closed. If the induction light curtain detects passengers in the descending space during the descent of the door body 300, the driving part 410 will immediately reverse again and drive the door body 300 to rise to the open door position. When the induction light curtain detects that there are no passengers, the door closing action is restarted. After the door is closed, a cycle of opening and closing the door is completed, and the next train is waiting for arrival.
