Description
Technical Field
[0001] This invention relates to the field of subway station platform technology, specifically to a subway station platform safety protection device. Background Technology
[0002] The subway platform is located between the up and down train lines. This layout makes the platform area highly utilized, can regulate passenger flow, makes it convenient for passengers to change their travel direction midway, centralizes station management, and provides a spacious platform. For example, passengers can board the train from both sides of the island platform, which is suitable for stations with high passenger flow. It also occupies a small area, allows for same-platform transfers, and has a lower construction cost.
[0003] For example, the authorization announcement number "CN211107387U" describes a subway station platform safety protection device. This device uses two locking frames to secure a locking plate. When the user needs to remove the plate, they simply pull a lever to move the plate upwards, separating it from the frames and completing the removal. This makes the device easy to assemble and disassemble later. However, existing subway station platform safety protection devices have limitations. Because subway trains enter the platform at high speeds, and the airflow generated by the train is also significant, people and items near the platform can be swept into the subway tracks, posing a danger. Therefore, the current subway station platform safety protection devices have relatively poor protective capabilities.
[0004] Meanwhile, the existing platform safety protection devices in subway stations have limitations. In subway operation, passengers need to wait for the subway to come to a smooth stop before the subway doors open and they can board. A single subway train may have many doors, but there are no pedestrian and passenger restraint or guidance structures in front of the subway doors. As a result, some passengers will push forward to catch the subway, and passengers getting off the subway will also push outward, which will cause conflicts, collisions, trampling and other dangers, which will greatly affect the safety of the subway station platform safety protection devices. Summary of the Invention
[0005] The purpose of this invention is to solve the problems of poor protection capability and low safety of existing subway station platform safety protection devices, and to propose a subway station platform safety protection device.
[0006] To achieve the above objectives, the present invention provides the following technical solution: Design a subway station platform safety protection device, including a subway platform, a platform door frame and a top plate. The platform door frame is fixedly installed at one end of the subway platform. The top plate is fixedly installed at the top of the platform door frame. The inner side of the platform door frame is provided with a subway car door protection opening structure. The inside of the platform door frame is provided with a platform door opening drive structure. The inner side of the subway platform is provided with a lifting passenger guidance structure.
[0007] Preferably, the subway door protective opening structure includes a sliding groove and a storage groove. The storage groove is fixedly opened on the inner side of the platform door frame, and the sliding groove is fixedly opened on the top of the subway platform. Two platform doors are slidably connected to the inner side of the sliding groove. Sealing gaskets are fixedly fitted on the outer walls of the two platform doors. Multiple pulleys are rotatably installed at the lower ends of the two platform doors, and the multiple pulleys are slidably connected to the bottom end of the sliding groove. Preferably, a stop indicator is fixedly installed at the front end of the two platform doors, and the sides of the two platform doors are slidably connected to the inner side of the storage slot.
[0008] Preferably, the platform door opening drive structure includes a reserved cavity and cylinders. The reserved cavity is fixedly opened on the inner side of the top of the platform door. Cylinders are fixedly installed on both sides of the inner wall of the reserved cavity. Connecting blocks are fixedly installed at the front ends of the two cylinders. The lower ends of the two connecting blocks are fixedly connected to one side of the top of the platform door.
[0009] Preferably, the lifting passenger guidance structure includes electric push rods and protrusions. Multiple electric push rods are fixedly installed on the inner side of the subway platform, and protrusions are fixedly installed on the top of the multiple electric push rods. Lights are fixedly installed on the side walls of the multiple protrusions, and horizontal handrails are fixedly installed on the other side of the outer wall of the multiple protrusions.
[0010] Preferably, a subway train number display screen is fixedly installed at the front end of the top plate.
[0011] The present invention proposes a subway station platform safety protection device, which has the following advantages: the pulleys connected to the lower end of the platform door by bearings can slide left and right in the sliding groove. This sliding pulley reduces the friction between the platform door and the sliding groove, making the opening smoother. The sealing gasket is made of rubber material and is wrapped around the edge of the platform door. This fills the gap in the middle after the platform door is closed. When the subway enters the platform, the two platform doors are in a closed state, thus separating passengers from the subway and reducing the risk of being pulled into the subway tracks, thereby improving the protective capability of the subway station platform safety protection device.
[0012] Multiple electric push rods are arranged side by side, with protrusions fixedly installed at their tops. When there are few passengers, the push rods will pull the protrusions back into the subway platform. When there are many passengers and conflicts are likely to occur when getting on and off the subway, the push rods will be connected to the power source and activated. The push rods will push the protrusions up, and the protrusions, together with the horizontal handrails on both sides, will form a passage corresponding to the platform door. Passengers getting on and off the subway will walk along the planned passage on the right side. This can reduce the occurrence of pedestrian congestion and conflicts and improve the safety performance of the subway station platform safety protection device. Attached Figure Description

[0017] The subway car door protective opening structure 5 includes a sliding groove 51 and a storage groove 52. The storage groove 52 is fixedly opened on the inner side of the platform door frame 2. The size of the storage groove 52 is larger than the width of the platform door 54, so that the platform door 54 will slide into the storage groove 52 after opening. The sliding groove 51 is fixedly opened on the top of the subway platform 1. Two platform doors 54 are slidably connected to the inner side of the sliding groove 51. The lower end of the platform door 54 is connected to a pulley 55 by a bearing, which can slide left and right in the sliding groove 51.
[0018] The sliding pulleys 55 reduce the friction between the platform door 54 and the slide rail 51, making the opening smoother. The outer walls of the two platform doors 54 are fixedly fitted with sealing gaskets 53, which are made of rubber material. The rubber sealing gaskets 53 are wrapped around the edges of the platform doors 54, so that they can fill the gap in the middle after the platform doors 54 are closed. Multiple pulleys 55 are rotatably installed at the lower end of the two platform doors 54, and the multiple pulleys 55 are slidably connected to the bottom end of the slide rail 51. Since the size of the storage slot 52 is larger than the width of the platform door 54, the platform door 54 will slide into the storage slot 52 after it is opened. The pulley 55 connected to the lower end of the platform door 54 by the bearing can slide left and right in the slide groove 51. The sliding pulley 55 reduces the friction between the platform door 54 and the slide groove 51, making the opening smoother. The sealing gasket 53 is made of rubber material.
[0019] The rubber sealing gasket 53 is wrapped around the edge of the platform door 54, so that it can fill the gap in the middle after the platform door 54 is closed. When the subway enters the platform, the two platform doors 54 are closed, thus separating passengers from the subway, reducing the danger of being pulled into the subway tracks, and improving the protective capability of the subway station platform safety protection device.
[0020] Stop signs 8 are fixedly installed at the front ends of the two platform screen doors 54. The stop signs 8 are made of bright red prohibition signs. After the two platform screen doors 54 are closed, the stop signs 8 will prompt passengers to stay away from the platform screen doors 54 to avoid accidents. The sides of the two platform screen doors 54 are slidably connected to the inside of the storage slot 52. The platform door opening drive structure 6 includes a reserved cavity 61 and cylinders 62. The reserved cavity 61 is fixedly opened on the inner side of the top of the platform door 2. Cylinders 62 are fixedly installed on both sides of the inner wall of the reserved cavity 61. After the cylinders 62 are connected to the power supply, they can slide left and right in the internal space of the reserved cavity 61. The front end of the cylinder 62 pulls the connecting block 63 to separate or move together at the same time. In this way, the connecting block 63 drives the lower platform door 54 to realize the opening and closing operation. The front end of the two cylinders 62 is fixedly installed with the connecting block 63, and the lower end of the two connecting blocks 63 is fixedly connected to one side of the top of the platform door 54.
[0021] The lifting passenger guidance structure 7 includes electric push rods 71 and protrusions 72. Multiple electric push rods 71 are fixedly installed on the inner side of the subway platform 1. Multiple electric push rods 71 are arranged in parallel side by side. Protrusions 72 are fixedly installed on the top of multiple electric push rods 71. When there are few passengers, multiple electric push rods 71 will pull the top protrusions 72 back into the subway platform 1. When there are many passengers and conflicts may occur when getting on and off the subway, multiple electric push rods 71 are connected to the power supply and activated. The electric push rods 71 can push multiple protrusions 72 to the top.
[0022] The protrusion 72, together with the horizontal handrails 74 on both sides, can form a passage corresponding to the platform door 54. Passengers getting on and off the subway can walk along the planned passage on the right side, which can reduce the occurrence of pedestrian congestion and conflict. The side walls of the multiple protrusions 72 are fixedly installed with light lamps 73, which can be LED lamp beads, and can emit brightness to guide pedestrians to pass. The other side of the outer wall of the multiple protrusions 72 is fixedly installed with a horizontal handrail 74. Multiple electric push rods 71 are arranged in parallel side by side. Each electric push rod 71 has a protrusion 72 fixedly installed at its top. When there are few passengers, the multiple electric push rods 71 will pull the top protrusion 72 back into the subway platform 1. When there are many passengers and conflicts are likely to occur when getting on and off the subway, the multiple electric push rods 71 are connected to the power supply and activated. The electric push rods 71 can push the multiple protrusions 72 to the top. The protrusions 72, together with the horizontal handrails 74 on both sides, can form a passage corresponding to the platform door 54. Passengers getting on and off the subway can walk along the planned passage on the right side. This can reduce the occurrence of pedestrian congestion and conflicts and improve the safety performance of the subway station platform safety protection device.
[0023] Working principle: The platform safety protection device of the subway station is installed on the side of the subway station platform closest to the subway track.
