[0018] In order to make the objectives, technical solutions and advantages of the present application more clearly understood, the present application is further described in detail below in combination with specific embodiments and with reference to the accompanying drawings.

[0019] It should be noted that, unless otherwise defined, the technical terms or scientific terms used in the embodiments of the present application should be the usual meanings understood by people with ordinary skills in the field to which the present application belongs. The "first", "second" and similar words used in the embodiments of the present application do not represent any order, quantity or importance, but are only used to distinguish different components. "Including" or "comprising" and similar words mean that the elements or objects appearing in front of the word cover the elements or objects listed after the word and their equivalents, without excluding other elements or objects. "Connect" or "connected" and similar words are not limited to physical or mechanical connections, but can include electrical connections, whether direct or indirect. "Up", "down", "left", "right" and the like are only used to indicate relative positional relationships. When the absolute position of the described object changes, the relative positional relationship may also change accordingly.

[0020] Based on the background, the gap between the platform and the train is the result of multiple factors, including the physical characteristics of the train and platform structures, thermal expansion and contraction effects, track adjustment requirements, and the accuracy of train stops. In order to prevent passengers from stepping on empty space when getting on and off the train, an anti-stepping device is installed on the platform to fill the gap. However, the anti-stepping device can only reduce the gap, but cannot completely eliminate it. Therefore, passengers' shoes may still get stuck in the gap, which not only causes discomfort and panic to passengers, but may also affect the normal operation order of the train.

[0021] The disassembly and maintenance process of current anti-stepping devices is usually complicated and requires professional tools and skills. When an emergency occurs, such as a shoe being stuck, it is often necessary to wait for professionals to arrive for rescue, which greatly prolongs the time to resume operations. During peak hours, such delays can have a serious impact on the travel of a large number of passengers.

[0022] In order to solve the above problems, the present application provides a quick-detachable anti-stepping device for platform doors.

[0023] The following is combined with Figure 1-6 The embodiments of the present application will be described in detail.

[0024] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the present application provides a quick-detachable anti-stepping device for platform doors, comprising: The rubber strip 1 is provided between the train and the platform, and a clamping portion 11 is provided at the bottom thereof; The rubber strip bracket 2 is used to connect with the platform. Part of the rubber strip bracket 2 is arranged at the bottom of the rubber strip 1 and is provided with a first through hole 211 therethrough. The clamping portion 11 passes through the first through hole 211. The locking plug plate 3 is arranged on a side of the rubber strip bracket 2 away from the rubber strip 1. The locking plug plate 3 is provided with a second through hole 31. The clamping portion 11 passes through the second through hole 31. The locking plug plate 3 is slidably connected with the rubber strip bracket 2 in the length direction, so as to slide until the clamping portion 11 is clamped with the locking plug plate 3; or slide until the clamping portion 11 is unclamped from the locking plug plate 3, so that the clamping portion 11 is removed from the first through hole 211 and the second through hole 31.

[0025] Specifically, the rubber strip 1, the rubber strip bracket 2 and the locking plug plate 3 are all set in a long strip shape and are set in the gap between the train and the platform. For example, the length of the rubber strip 1 is 1100mm, the height is 71.6mm, and the width is 40mm. The width of the rubber strip 1 can be further reduced according to demand. The rubber strip 1 can be directly connected to the side wall of the subway platform through the rubber strip bracket 2, or it can be connected to the threshold 02 set on the edge of the subway platform through the rubber strip bracket 2. The rubber strip bracket 2 and the threshold 02 can be connected by bolts to facilitate the installation and removal of the rubber strip bracket 2. The rubber strip 1 is made of low-smoke halogen-free flame retardant, insulating, wear-resistant, and anti-aging rubber material to ensure that the rubber strip 1 can maintain a stable shape for a long time under the vibration of train operation and the trampling of passengers, reducing the frequency of replacement. The rubber strip bracket 2 and the locking plug plate 3 are made of Q235B carbon steel and are hot-dip galvanized to increase their service life. A light strip assembly 9 is also provided on the rubber strip 1 to remind passengers to pay attention to the gap here to avoid stepping on the air. The clamping portion 11 is a hook, which is fixed on the rubber strip 1. The hook passes through the first through hole 211 and the second through hole 31 to achieve the connection between the rubber strip 1, the rubber strip bracket 2 and the locking plug plate 3. The rubber strip bracket 2 and the rubber strip 1 are fixed in position, and the locking plug plate 3 slides under the rubber strip bracket 2. Since the rubber strip bracket 2 and the rubber strip 1 are fixed in position, the first through hole 211 and the hook are fixed in position. When the locking plug plate 3 slides, the second through hole 31 moves accordingly, and the first through hole 211 and the second through hole 31 are misaligned. At this time, the hook is clamped with the locking plug plate 3, thereby achieving the fixation of the rubber strip 1 and the rubber strip bracket 2; and when the locking plug plate 3 continues to slide, the hook is unclamped from the locking plug plate 3, and when the first through hole 211 is concentric with the second through hole 31, the hook can be removed from the first through hole 211 and the second through hole 31, thereby facilitating the rapid separation of the rubber strip 1 and the rubber strip bracket 2.

[0026] In this embodiment, a quick-release anti-stepping device for platform doors includes a rubber strip 1, a rubber strip bracket 2 and a locking plug plate 3. The rubber strip 1 is used to narrow the gap between the train and the platform. The rubber strip bracket 2 is used to receive the rubber strip 1. The rubber strip 1 is arranged on the rubber strip bracket 2, and the positions of the two are relatively fixed. The locking plug plate 3 is located at the bottom of the rubber strip bracket 2 and slides on the rubber strip bracket 2. The rubber strip bracket 2 is provided with a first through hole 211, and the locking plug plate 3 is provided with a second through hole 31. A clamping portion 11 is fixedly provided at the bottom of the rubber strip 1, and the clamping portion 11 passes through the first through hole 211 and the second through hole 31. When the locking plug plate 3 slides, the second through hole 31 moves accordingly until the clamping portion 11 is clamped with the locking plug plate 3, thereby achieving the fixation of the rubber strip 1 and the rubber strip bracket 2. When a passenger's shoe is stuck in the gap between the rubber strip 1 and the train, the locking plate 3 is controlled to slide, and the clamping portion 11 is released from the locking plate 3 until the first through hole 211 is concentric with the second through hole 31. At this time, the hook is removed from the first through hole 211 and the second through hole 31, thereby realizing the rapid disassembly of the rubber strip 1, so as to quickly rescue the passengers, shorten the rescue time, and avoid affecting the normal operation of the train.

[0027] In some embodiments, Figure 3 and Figure 4 As shown, a quick-release anti-stepping device for platform doors also includes a latch 4. When the clamping portion 11 is in clamping connection with the locking plug plate 3, the latch 4 penetrates the rubber strip bracket 2 and the locking plug plate 3 to lock the clamping effect of the clamping portion 11 on the locking plug plate 3.

[0028] Specifically, the rubber strip bracket 2 is provided with a first insertion hole 212 that penetrates therethrough, and the locking plug plate 3 is provided with a second insertion hole 32 that penetrates therethrough. When the latch pin 4 is inserted into the first insertion hole 212 and the second insertion hole 32, the clamping portion 11 penetrates the first through hole 211 and the second through hole 31, the first through hole 211 and the second through hole 31 are misaligned, and the clamping portion 11 is clamped with the locking plug plate 3; when the latch pin 4 is not inserted into the first through hole 212 and the second through hole 32, the first through hole 211 and the second through hole 31 are concentric, so that the clamping portion 11 can be taken out of the first through hole 211 and the second through hole 31.

[0029] In this embodiment, when the clamping portion 11 is successfully clamped with the locking plug plate 3, the latch 4 provides an additional locking mechanism for the clamping action, which prevents the rubber strip 1 from being unlocked due to external force or unexpected circumstances, thereby improving the stability of the installation and use of the rubber strip 1. When the rubber strip 1 needs to be unlocked, it is only necessary to simply pull out the latch 4 from the first plug hole 212 and the second plug hole 32, so that the first perforation 211 and the second perforation 31 can be restored to a concentric state. At this time, the clamping portion 11 can be easily removed from the perforation, thereby achieving the purpose of rapid disassembly of the rubber strip 1. Therefore, the anti-stepping device does not require tools for disassembly when rescuing passengers, and does not require the presence of professionals. Station staff can independently operate and complete the disassembly after simple training, which saves precious rescue time for operating staff, reduces the damage to passengers who step on the air, quickly resumes operations, and avoids causing stampedes.

[0030] In some embodiments, Figure 4 , Figure 5 and Figure 6 As shown, a quick-detachable anti-stepping device for a subway platform door also includes a spring assembly 5, including a first mounting block 51, a second mounting block 52 and a spring 53. The first mounting block 51 is mounted at the bottom of the rubber strip bracket 2, and the second mounting block 52 is mounted on one side of the locking plug plate 3. The spring 53 is fixedly connected between the first mounting block 51 and the second mounting block 52. When the latch 4 locks the locking action of the locking plug plate 3 by the clamping portion 11, the spring 53 is in a compressed state, so that when the latch 4 is pulled out from the locking plug plate 3, the locking plug plate 3 slides relative to the rubber strip bracket 2 to the clamping portion 11 and releases the locking plug plate 3 through the rebound force of the spring 53.

[0031] Specifically, the latch 4 is arranged at one end of the rubber strip bracket 2, and the spring assembly 5 is arranged at the end of the rubber strip bracket 2 away from the latch 4. In order to facilitate the installation of the first mounting block 51, the first mounting block 51 is installed below the rubber strip bracket 2 by bolts, and in order to facilitate the installation of the second mounting block 52, the second mounting block 52 is installed below the locking plug plate 3 by bolts. The spring 53 is located between the first mounting block 51 and the second mounting block 52, and one end of the first mounting block 51 extends into the spring 53, and one end of the second mounting block 52 extends into the spring 53, which guides the expansion and contraction of the spring 53. When the latch 4 is inserted into the first insertion hole 212 and the second insertion hole 32, the clamping portion 11 passes through the first through hole 211 and the second through hole 31, the first through hole 211 and the second through hole 31 are misaligned, the clamping portion 11 is clamped with the locking plug plate 3, and the spring 53 is in a compressed state; when the latch 4 is pulled out of the first insertion hole 212 and the second insertion hole 32, the rebound force of the spring 53 causes the locking plug plate 3 to slide relative to the rubber strip bracket 2 until the first through hole 211 is concentric with the second through hole 31, and the clamping portion 11 is released from the locking plug plate 3, so that the rubber strip 1 is separated from the rubber strip bracket 2.

[0032] In the present embodiment, when the latch 4 locks the engagement of the locking plate 3 with the engaging portion 11, the spring 53 is in a compressed state. At this time, after the latch 4 is inserted into the first insertion hole 212 and the second insertion hole 32 and locked, the spring 53 stores a certain amount of energy. When unlocking is required, only the latch 4 needs to be pulled out, and the rebound force of the spring 53 can automatically push the locking plate 3 to slide, so that the engaging portion 11 is released from the locking plate 3, and the first through hole 211 is concentric with the second through hole 31, so that the engaging portion 11 is conveniently removed from the first through hole 211 and the second through hole 31, so that the rubber strip 1 can be separated from the rubber strip bracket 2. The spring assembly 5 automatically realizes the unlocking and locking of the locking plate 3 with respect to the engaging portion 11 by cooperating with the latch 4, thereby improving the installation and disassembly efficiency of the rubber strip 1.

[0033] In some embodiments, Figure 4 As shown, a slide groove 33 is provided on the locking plug plate 3 in the length direction, and the rubber strip bracket 2 is fixedly connected with a connecting piece 331 penetrating the slide groove 33 for connecting the locking plug plate 3 and the rubber strip bracket 2 .

[0034] Specifically, the connecting member 331 is a bolt, which is fixedly connected to the rubber strip bracket 2 , passes through the slide slot 33 , and the bolt head abuts against the locking plug plate 3 to achieve a sliding connection between the locking plug plate 3 and the rubber strip bracket 2 .

[0035] In this embodiment, the connecting member 331 guides the sliding of the locking plug plate 3, and the connecting member 331 connects the locking plug plate 3 and the rubber strip bracket 2 to improve the structural stability of both. At the same time, the connecting member 331 does not affect the sliding of the locking plug plate 3, ensuring that the locking process and unlocking process of the locking plug plate 3 on the clamping part 11 are carried out normally.

[0036] In some embodiments, Figure 3 As shown, the rubber strip bracket 2 includes a first bracket 21 and a second bracket 22. The first bracket 21 is located at the bottom of the rubber strip 1 for installing the rubber strip 1. The second bracket 22 is arranged on one side of the second bracket 22 for connecting to the threshold 02 on the platform. In this embodiment, the first bracket 21 is located at the bottom of the rubber strip 1, and its main function is to install and support the rubber strip 1, ensuring that the rubber strip 1 can be firmly fixed to the edge of the platform door to prevent passengers from stepping on it. The second bracket 22 is arranged on one side of the first bracket 21, and its main function is to connect the threshold 02 on the platform, fix the rubber strip bracket 2 as a whole to the station structure, and enhance the stability and safety of the entire structure.

[0037] In some embodiments, Figure 3 and Figure 4 As shown, the latch 4 includes an insertion rod 41, a plug 42 and a pull ring 43. The plug 42 is arranged on one side of the insertion rod 41, and the pull ring 43 is arranged on the side of the plug 42 away from the insertion rod 41; the strip bracket 2 is provided with a first plug hole 212, and the locking plug plate 3 is provided with a second plug hole 32. When the latch 4 locks the clamping effect of the clamping part 11 on the locking plug plate 3, the insertion rod 41 passes through the first plug hole 212 and the second plug hole 32.

[0038] In addition, a limiting block 6 is fixedly connected to the first bracket 21 . The limiting block 6 is located at a side of the plug 42 away from the rubber strip 1 and is provided with a limiting groove 61 . The plug 42 is provided with a protrusion 421 . The limiting groove 61 is plugged into the protrusion 421 .

[0039] Specifically, when the latch 4 locks the locking action of the locking portion 11 on the locking plate 3, the plug 41 passes through the first socket 212 and the second socket 32, and the plug 42 is arranged above the plug 41 and abuts against the first bracket 21 to prevent the plug 41 from falling out of the first socket 212 and the second socket 32, thereby improving the stability of the plug 41. The first socket 212 and the second socket 32 ​​are configured as square holes, and the plug 41 is also configured as a rectangular parallelepiped to limit the shaking of the plug 41 when subjected to external vibrations, thereby further improving the stability of the plug 41.

[0040] In this embodiment, the plug rod 41 is the main connecting component, which passes through the first plug hole 212 and the second plug hole 32 to achieve the locking of the clamping part 11 and the locking plug plate 3. The plug 42 prevents the plug rod 41 from falling out of the first plug hole 212 and the second plug hole 32, thereby improving the stability of the plug rod 41 in the first plug hole 212 and the second plug hole 32. The pull ring 43 is arranged on the side of the plug 42 away from the plug rod 41, providing a convenient grip point for the operator, making the insertion and removal process of the plug 4 easier and more efficient. When the plug 4 is inserted into the first plug hole 212 and the second plug hole 32, the protrusion 421 will be inserted into the limit groove 61, forming a locking mechanism for the plug 4, limiting the movement range of the plug 42, improving the stability of the plug 4, and preventing the plug 4 from accidentally falling out when subjected to external force.

[0041] In some embodiments, Figure 4 As shown, a quick-detachable anti-stepping device for a subway platform door also includes a detection component 7 and an alarm component. The detection component 7 is installed on the locking plug plate 3 to detect whether the rubber strip 1 is detached from the first bracket 21. The alarm component is connected to the detection component 7. When the detection component 7 detects that the rubber strip 1 is detached from the first bracket 21, the alarm component sends a warning signal to the operator and passengers.

[0042] Specifically, the detection component 7 includes a detector body 71, a swing arm 72 and a roller 73. The locking plate 3 is provided with a first connecting hole 34, and the rubber strip bracket 2 is provided with a second connecting hole 213. The first connecting hole 34 is connected to the second connecting hole 213. The detector body 71 is installed at the bottom of the locking plate 3, and its top extends into the first connecting hole 34. The swing arm 72 and the roller 73 extend into the second connecting hole 213. A push switch 711 is provided on the top of the detector body 71. The swing arm 72 and the roller 73 are rotatably connected to one side of the detector body 71. When the alarm component does not send a warning signal to the passenger, the roller 73 abuts against the rubber strip 1, and the swing arm 72 presses the push switch 711; when the alarm component sends a warning signal to the operator and the passenger, the push switch 711 is in a natural state. The alarm component is an audible and visual alarm, which can be installed on the side end face of the column platform. The cable is connected to the audible and visual alarm through the tube of the platform door column. The sound content and display mode of this audible and visual alarm can be customized. When the rubber strip 1 is 1.5mm away from the upper end face of the rubber strip bracket 2, the detection switch component is triggered, and the signal is transmitted to the door control unit. The door control unit controls the audible and visual alarm to broadcast and display the sound according to the predefined content and mode, so that the station staff can find the loose anti-stepping device and deal with it in time. At the same time, this audible and visual alarm can also broadcast order-maintaining content such as "There is a passenger stepping on the air here, do not approach, please move away in an orderly manner and make way for the rescue passage" during rescue, reducing the pressure on the station staff to shout, so that the station staff can concentrate more on the rescue work and quickly resume operations.

[0043] In this embodiment, the detection component 7 is installed on the first bracket 21 and the locking plug plate 3, and can monitor the status of the rubber strip 1 in real time to ensure timely detection of whether the rubber strip 1 is detached from the first bracket 21. This real-time monitoring mechanism greatly reduces the safety hazards caused by the detachment of the rubber strip 1. Once the detection component 7 detects that the rubber strip 1 is detached from the first bracket 21, the alarm component will immediately send a warning signal to the passenger. This timely warning can effectively remind the passenger to pay attention to the safety of his feet and avoid accidents of stepping into the air. Through the synergistic effect of the detection component 7 and the alarm component, the device can detect and warn passengers as soon as the rubber strip 1 falls off, thereby effectively preventing platform door accidents caused by the detachment of the rubber strip 1.

[0044] In some embodiments, Figure 3 and Figure 4 As shown, an isolation block 8 is provided on a side of the plug 42 away from the limiting block 6 , and the isolation block 8 is used to separate the plug 42 and the rubber strip 1 to prevent the rubber strip 1 from adhering to the pin 4 .

[0045] Specifically, a first placement groove is provided at one end of the rubber strip 1 close to the plug 4 , and the isolation block 8 is arranged in the first placement groove. A plug 42 is provided on one side of the isolation block 8 . The isolation block 8 is a metal block used to separate the rubber strip 1 and the plug 4 .

[0046] In this embodiment, the isolation block 8 prevents the rubber strip 1 , whose main body is made of rubber material, from becoming sticky due to long-term contact with the latch 4 , thereby hindering the corresponding pulling-out action of the latch 4 .

[0047] In some embodiments, Figure 4 and Figure 5 As shown, a limiting column 81 is provided on the side of the rubber strip bracket 2 away from the latch 4 to limit the relative position of the rubber strip 1 and the rubber strip bracket 2, and an isolation pad 82 is provided between the limiting column 81 and the rubber strip 1 to prevent the limiting column 81 from adhering to the rubber strip 1.

[0048] Specifically, a second mounting groove is provided at one end of the rubber strip 1 away from the latch pin 4, and a limiting column 81 is provided in the second mounting groove. During the installation of the rubber strip 1, the limiting column 81 is inserted into the second mounting groove, and the rubber strip 1 is abutted against the limiting column 81 to limit the relative position between the rubber strip 1 and the rubber strip bracket 2 and accurately position the rubber strip 1, thereby keeping the end of the rubber strip 1, the rubber strip bracket 2 and the end of the locking plate 3 flush to improve the regularity of the anti-stepping device.

[0049] In this embodiment, the limiting column 81 positions the rubber strip 1 during the installation process of the rubber strip 1. When the rubber strip 1 is in use, the relative position between the rubber strip 1 and the rubber strip bracket 2 is limited, thereby enhancing the stability of the rubber strip 1. The isolation pad 82 prevents the rubber strip 1, which is mainly made of rubber material, from becoming sticky due to long-term contact with the limiting column 81, thereby hindering the corresponding removal action of the rubber strip 1.

[0050] In summary, the present application provides a platform door quick-release anti-stepping device, which mainly includes a rubber strip 1, a rubber strip bracket 2, a locking plug plate 3, a latch 4 and a spring assembly 5. The rubber strip 1 is used to narrow the gap between the train and the platform. The rubber strip bracket 2 and the locking plug plate 3 are used to install the rubber strip 1. The rubber strip 1 is arranged on the rubber strip bracket 2, and the positions of the two are relatively fixed. The locking plug plate 3 is located at the bottom of the rubber strip bracket 2 and slides on the rubber strip bracket 2. The rubber strip bracket 2 is provided with a first through hole 211 and a first plug hole 212. The locking plug plate 3 is provided with a first through hole 211 and a first plug hole 212.
