DETAILED DESCRIPTION

[0027] In order to make the objectives, technical solutions and advantages of this application more clear, this application is further described in detail below in combination with specific embodiments and with reference to the accompanying drawings.

[0028] It should be noted that, unless otherwise defined, the technical terms or scientific terms used in the embodiments of the present application should have the usual meanings understood by people with ordinary skills in the field to which this application belongs. The "first", "second" and similar words used in the embodiments of the present application do not indicate any order, quantity or importance, but are only used to distinguish different components. "Include" or "comprise" and similar words mean that the elements or objects appearing before 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 may 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.

[0029] As mentioned in the background, the gap between the platform and the train is the result of a combination of factors, including the physical properties of the train and platform structures, thermal expansion and contraction, track adjustment requirements, and the accuracy of train stops. To prevent passengers from stepping on air when getting on and off the train, anti-aircraft devices are installed on the platform to fill the gap. However, these devices can only narrow the gap, not completely eliminate it. Therefore, passengers' shoes may still get stuck in the gap, which not only causes discomfort and panic for passengers, but may also affect the normal operation of the train.

[0030] The installation and maintenance of existing anti-skid devices is often complex and requires specialized tools and skills. In emergencies like shoe jams, there's often a wait for specialized personnel to arrive, significantly delaying service resumption. During peak hours, these delays can severely impact the travel of numerous passengers.

[0031] In order to solve the above problems, the present application provides a quick-detachable anti-stepping device for platform doors.

[0032] The following is combined with Figure 1-6 The embodiments of the present application will be described in detail.

[0033] 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:

[0034] The rubber strip 1 is provided between the train and the platform, and has a clamping portion 11 at its bottom;

[0035] The rubber strip bracket 2 is used to connect to the platform. Part of the rubber strip bracket 2 is provided 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.

[0036] The locking plug plate 3 is provided on the 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 to 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 disengaged 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.

[0037] Specifically, the rubber strip 1, rubber strip bracket 2, and locking plate 3 are all designed in a long, strip-like shape and installed in the gap between the train and the platform. For example, the rubber strip 1 is 1100mm long, 71.6mm high, and 40mm wide. The width of the rubber strip 1 can be further reduced as needed. The rubber strip 1 can be directly attached to the side wall of the subway platform via the rubber strip bracket 2, or it can be attached to the threshold 02 located at the edge of the subway platform. The rubber strip bracket 2 and threshold 02 are connected by bolts, facilitating installation and removal of the rubber strip bracket 2. The rubber strip 1 is made of a low-smoke, halogen-free, flame-retardant, insulating, wear-resistant, and aging-resistant rubber material, ensuring that the rubber strip 1 maintains its shape over time despite train vibrations and passenger traffic, reducing replacement frequency. The rubber strip bracket 2 and locking plate 3 are made of Q235B carbon steel and are hot-dip galvanized to extend their service life. The rubber strip 1 also features a light strip assembly 9 to alert passengers to the gap and prevent them from stepping on it. When the locking 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 engaged with the locking plate 3, thereby achieving the fixation of the rubber strip 1 and the rubber strip holder 2; and when the locking plate 3 continues to slide, the hook is released from the locking plate 3, and when the first through-hole 211 and the second through-hole 31 are concentric, 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 holder 2.

[0038] In this embodiment, a quick-release anti-stepping device for a platform door 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 fixed to 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 engaging portion 11 is disengaged from the locking plate 3 until the first through-hole 211 and the second through-hole 31 are concentric. 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 passenger, shorten the rescue time, and avoid affecting the normal operation of the train.

[0039] In some embodiments, as 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 clamped with the locking plate 3, the latch 4 passes through the rubber strip bracket 2 and the locking plate 3 to lock the clamping effect of the clamping portion 11 on the locking plate 3.

[0040] Specifically, the rubber strip bracket 2 is provided with a first insertion hole 212 that passes through it, and the locking plate 3 is provided with a second insertion hole 32 that passes through it. 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, and the clamping portion 11 is clamped with the locking plate 3; when the latch 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 removed from the first through-hole 211 and the second through-hole 31.

[0041] In this embodiment, after the engaging portion 11 is successfully engaged with the locking plate 3, the latch 4 provides an additional locking mechanism for the engaging action, preventing the rubber strip 1 from being unlocked due to external forces 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, the latch 4 can be simply pulled out from the first socket 212 and the second socket 32 ​​to restore the first perforation 211 and the second perforation 31 to a concentric state. At this time, the engaging portion 11 can be easily removed from the perforation, thereby achieving the purpose of quickly disassembling the rubber strip 1. Therefore, when rescuing passengers, the anti-stepping device does not require tools for disassembly, and no professional personnel are required. Station staff can independently complete the disassembly after simple training, which buys valuable rescue time for operating staff, reduces injuries to passengers who stepping in the air, quickly resumes operations, and avoids causing stampedes.

[0042] In some embodiments, as Figure 4 、 Figure 5 and Figure 6 As shown, a quick-release 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 installed at the bottom of the rubber strip bracket 2, and the second mounting block 52 is installed 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 rebound force of the spring 53 causes the locking plug plate 3 to slide relative to the rubber strip bracket 2 to the clamping portion 11 and to release the clamping action from the locking plug plate 3.

[0043] Specifically, the latch 4 is located at one end of the rubber strip bracket 2, and the spring assembly 5 is located at the end of the rubber strip bracket 2 away from the latch 4. To facilitate installation of the first mounting block 51, the first mounting block 51 is bolted to the underside of the rubber strip bracket 2. To facilitate installation of the second mounting block 52, the second mounting block 52 is bolted to the underside of the locking plate 3. The spring 53 is located between the first mounting block 51 and the second mounting block 52, with one end of the first mounting block 51 extending into the spring 53, while one end of the second mounting block 52 extends into the spring 53, guiding 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 from 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.

[0044] In this embodiment, when the latch 4 locks the engagement of the locking portion 11 with the locking plate 3, the spring 53 is in a compressed state. At this time, after the latch 4 is inserted into the first hole 212 and the second hole 32 and locked, the spring 53 stores a certain amount of energy. When unlocking is required, it is only necessary to pull out the latch 4. The rebound force of the spring 53 can automatically push the locking plate 3 to slide, so that the engagement of the locking portion 11 and the locking plate 3 are released, and the first through-hole 211 is concentric with the second through-hole 31, so that the locking portion 11 is easily removed from the first through-hole 211 and the second through-hole 31, thereby allowing the rubber strip 1 to be separated from the rubber strip bracket 2. The spring assembly 5 automatically unlocks and locks the locking plate 3 with respect to the locking portion 11 by cooperating with the latch 4, thereby improving the installation and removal efficiency of the rubber strip 1.

[0045] In some embodiments, as Figure 4 As shown, a sliding groove 33 is provided on the length direction of the locking plug plate 3, and the rubber strip bracket 2 is fixedly connected with a connecting piece 331 passing through the sliding groove 33 for connecting the locking plug plate 3 and the rubber strip bracket 2.

[0046] Specifically, the connecting member 331 is a bolt, which is fixedly connected to the rubber strip bracket 2 . The bolt passes through the slide groove 33 , and the bolt head abuts against the locking plate 3 to achieve a sliding connection between the locking plate 3 and the rubber strip bracket 2 .

[0047] In this embodiment, the connecting member 331 serves as a guide for the sliding of the locking plate 3, and the connecting member 331 connects the locking 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 plate 3, ensuring that the locking and unlocking processes of the locking plate 3 on the clamping portion 11 are carried out normally.

[0048] In some embodiments, as 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 located on one side of the second bracket 22 for connecting to the threshold 02 on the platform.

[0049] In this embodiment, the first bracket 21 is located at the bottom of the rubber strip 1. Its primary function is to mount and support the rubber strip 1, ensuring that it is securely fixed to the edge of the platform door to prevent passengers from stepping on it. The second bracket 22 is located on one side of the first bracket 21. Its primary function is to connect to the platform threshold 02, securing the rubber strip bracket 2 to the station structure and enhancing the stability and safety of the entire structure.

[0050] In some embodiments, as 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 rubber strip bracket 2 is provided with a first socket 212, and the locking plate 3 is provided with a second socket 32. When the latch 4 locks the clamping effect of the clamping part 11 on the locking plate 3, the insertion rod 41 passes through the first socket 212 and the second socket 32.

[0051] In addition, a limiting block 6 is fixedly connected to the first bracket 21 . The limiting block 6 is located on the 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 .

[0052] Specifically, when the latch 4 locks the locking action of the locking portion 11 on the locking plate 3, the insertion rod 41 passes through the first insertion hole 212 and the second insertion hole 32, and the plug 42 is arranged above the insertion rod 41 and abuts against the first bracket 21 to prevent the insertion rod 41 from falling out of the first insertion hole 212 and the second insertion hole 32, thereby improving the stability of the insertion rod 41. The first insertion hole 212 and the second insertion hole 32 are set as square holes, and the insertion rod 41 is also set as a rectangular parallelepiped to limit the shaking of the insertion rod 41 when subjected to external vibration, thereby further improving the stability of the insertion rod 41.

[0053] In this embodiment, the rod 41 serves as the primary connecting component, extending through the first and second insertion holes 212, 32 to lock the engaging portion 11 with the locking plate 3. The plug 42 prevents the rod 41 from falling out of the first and second insertion holes 212, 32, thereby improving the stability of the rod 41 within the first and second insertion holes 212, 32. The pull ring 43 is located on the side of the plug 42 away from the rod 41, providing a convenient grip point for the operator, making the insertion and removal of the latch 4 easier and more efficient. When the latch 4 is inserted into the first and second insertion holes 212, 32, the protrusion 421 engages with the retaining groove 61, forming a locking mechanism for the latch 4, limiting the range of movement of the plug 42, improving the stability of the latch 4, and preventing the latch 4 from accidentally falling out when subjected to external forces.

[0054] In some embodiments, as Figure 4 As shown, a quick-release anti-stepping device for subway platform doors also includes a detection component 7 and an alarm component. The detection component 7 is installed on the locking 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 operating personnel and passengers.

[0055] Specifically, the detection assembly 7 includes a detector body 71, a swing arm 72 and a roller 73. A first connecting hole 34 is provided on the locking plate 3, and a second connecting hole 213 is provided on the rubber strip bracket 2. 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 press 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 assembly does not issue a warning signal to the passenger, the roller 73 abuts the rubber strip 1 and the swing arm 72 presses the press switch 711; when the alarm assembly issues a warning signal to the operator and passengers, the press 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 content such as "There is a passenger stepping on air here, do not approach, please move away in an orderly manner and make way for the rescue passage" during rescue to maintain order, reducing the pressure on station staff to shout, so that station staff can focus more on rescue work and quickly resume operations.

[0056] In this embodiment, the detection assembly 7 is mounted on the first bracket 21 and the locking plate 3, enabling real-time monitoring of the status of the rubber strip 1, ensuring prompt detection of any detachment of the rubber strip 1 from the first bracket 21. This real-time monitoring mechanism significantly reduces the potential safety hazards caused by the detachment of the rubber strip 1. Once the detection assembly 7 detects that the rubber strip 1 has detached from the first bracket 21, the alarm assembly immediately issues a warning signal to passengers. This timely warning effectively reminds passengers to pay attention to their footing and avoid accidents involving stepping on empty space. Through the synergistic effect of the detection assembly 7 and the alarm assembly, the device can detect and alert passengers as soon as the rubber strip 1 is detached, effectively preventing platform door accidents caused by the detachment of the rubber strip 1.

[0057] In some embodiments, as 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 .

[0058] Specifically, a first placement groove is provided at one end of the rubber strip 1 close to the pin 4 , and an isolation block 8 is provided 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 pin 4 .

[0059] 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 prolonged contact with the latch 4 , thereby hindering the corresponding pulling-out action of the latch 4 .

[0060] In some embodiments, as 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 pin 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.

[0061] Specifically, a second mounting groove is provided at the end of the rubber strip 1 away from the latch 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.

[0062] In this embodiment, the limiting column 81 positions the rubber strip 1 during the installation process of the rubber strip 1. During the use of the rubber strip 1, the relative position between the rubber strip 1 and the rubber strip bracket 2 is restricted, thereby enhancing the stability of the rubber strip 1. The isolation pad 82 prevents the rubber strip 1, whose main body is made of rubber material, from becoming sticky due to long-term contact with the limiting column 81, thereby hindering the corresponding pulling-out action of the rubber strip 1.

[0063] In summary, the present application provides a quick-release anti-stepping device for platform doors, 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. The rubber strip 1 has two through-holes 31 and a second insertion hole 32. A latching portion 11 is fixed to the bottom of the rubber strip 1. The latching portion 11 extends through the first through-hole 211 and the second through-hole 31. When the locking plate 3 slides, the second through-hole 31 moves with it until the hook engages with the locking plate 3. The latch 4 then inserts into the first insertion hole 212 and the second insertion hole 32, providing an additional locking mechanism for the latching action. This prevents the rubber strip 1 from being unlocked due to external forces or accidents, thereby improving the stability of the installation and use of the rubber strip 1 and securing the rubber strip 1 to the rubber strip bracket 2. If a passenger's shoe becomes stuck in the gap between the rubber strip 1 and the train, simply pull the latch 4 out of the first insertion hole 212 and the second insertion hole 32. The spring assembly 5 drives the locking plate 3 to slide, restoring the first through-hole 211 and the second through-hole 31 to their concentric state. The latching portion 11 can then be easily removed from the through-holes, thus achieving the purpose of quickly removing the rubber strip 1, facilitating the rapid rescue of passengers, shortening rescue time, and preventing disruption to the normal operation of the train.
