Description

Technical Field

[0001] The present invention relates to the technical field of subway evacuation platforms, and in particular to a subway safety evacuation platform. Background Art

[0002] Subways are an essential part of urban transportation, boasting high transport efficiency. When an emergency occurs in a long and narrow tunnel and disrupts normal subway operations, evacuation platforms within the tunnel are needed to quickly and safely guide people to nearby platforms or adjacent safety tunnels.

[0003] The installation and maintenance of evacuation platforms is crucial for safe subway operation. When safety hazards are discovered during routine inspections, timely and adequate maintenance can be performed. This includes replacing cracked or corroded platforms and securing supporting structures. Although evacuation platforms are not frequently used, their safety must be considered from the perspective of emergencies. Emergencies present uncertain timing and damage levels, yet large numbers of passengers must be evacuated as quickly as possible. During emergencies, the platforms may be damaged or exacerbated by a stampede, necessitating urgent maintenance to ensure safe evacuation. Existing evacuation platforms are not conducive to timely and rapid replacement or repair of the platforms. Furthermore, during past emergencies, most people in the crowd are in a state of panic, making stampedes highly likely, causing additional injuries and significantly reducing evacuation efficiency. Compared to emergencies with lower casualties, shoving and trampling can cause more injuries. This is especially true when individuals in panic are unable to move quickly or move slowly, leading to increased shoving and crowding. This can lead to jams or falls in the crowd, hindering rapid evacuation.

[0004] The existing technology is not conducive to timely platform maintenance and repair in emergencies, which easily leads to low evacuation efficiency and needs to be solved. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to provide a subway safety evacuation platform in response to the above-mentioned technical deficiencies. It solves the problem in the existing technology that it is not conducive to timely maintenance and repair of the platform in emergencies, which easily leads to low evacuation efficiency. It is conducive to reducing pushing incidents and ensuring quick and safe evacuation.

[0006] The technical solution adopted by the present invention is to provide a subway safety evacuation platform, wherein a support beam and a handrail are provided on the wall, and the handrail is located above the support beam, comprising:

[0007] There are a plurality of first support plates, which are horizontally laid on the support beam, and the upper ends of the first support plates have a plurality of anti-slip protrusions, and the upper ends of the first support plates have at least one slideway arranged parallel to the evacuation direction;

[0008] A hook is movably arranged on the handrail;

[0009] The second support plate is vertically arranged and movably arranged above the first support plate on the side close to the wall. The second support plate is used to be horizontally laid on the upper end of the first support plate or for being horizontally laid on the support beam. The second support plate is detachably connected to the hook and the hook moves with the second support plate. The second support plate has at least one limit plate on the side away from the wall. When the second support plate is horizontally laid on the upper end of the first support plate, the limit plate slides in the slide parallel to the evacuation direction.

[0010] Further optimization of this technical solution also includes:

[0011] The sliding seat is sleeved on the lower part of the second supporting plate, and the sliding seat is slidably abutted against the upper end of the first supporting plate on the side close to the wall.

[0012] To further optimize the technical solution, the hook is movably arranged relative to the second support plate, and there is an adjustment gap between the anti-slip protrusion close to the wall and the wall. The sliding seat slides away from or close to the wall within the adjustment gap, and the lower part of the sliding seat has a limit baffle and a space-occupying baffle. The limit baffle is used to abut against the side of the anti-slip protrusion close to the wall, and the space-occupying baffle is perpendicular to the limit baffle. The space-occupying baffle is used to be inserted between two adjacent anti-slip protrusions in the evacuation direction.

[0013] Further optimization of this technical solution also includes:

[0014] The sleeve is slidably sleeved on the upper part of the second support plate parallel to the evacuation direction, and the sleeve is movable relative to the upper part of the second support plate. The sleeve is hinged at the lower end of the hook.

[0015] To further optimize this technical solution, the limit plate is located at the upper part of the second support plate away from the wall, one side of the housing is provided with a reinforcement plate, the reinforcement plate has an avoidance groove, and one of the limit plates moves in the avoidance groove.

[0016] To further optimize the technical solution, the second support plate has an anti-slip column on the side opposite to the wall, and the sliding seat has a socket for plugging and connecting with the anti-slip column.

[0017] Further optimization of this technical solution also includes:

[0018] A connecting plate is provided between every two adjacent support beams.

[0019] To further optimize the technical solution, a positioning block is provided on the support beam, and both the first support plate and the second support plate have a positioning groove that is plugged into and cooperates with the positioning block.

[0020] The beneficial effects of the present invention are:

[0021] 1. The second support plate is arranged vertically and connected to the hook. It can be more stably slid above the first support plate and against the wall. It is convenient to minimize the impact on the movement of evacuated personnel in an emergency. The staff quickly moves the nearby second support plate to the first support plate that needs to be replaced and maintained, covers the first support plate or replaces it to ensure support safety.

[0022] 2. The second support plate is in a vertical state and can be laid down to cover the first support plate, which makes the operation safer and more convenient. After the second support plate covers the first support plate, it can also be slid and adjusted to the specified position along the evacuation direction. The limit plate is in the slideway and can play a limiting role to prevent the second support plate from sliding outward from the first support plate.

[0023] 3. The second support plate is in a vertical position, close to the wall, to reduce space occupation, but it can still serve as a barrier. Slow-moving individuals can, on their own or under the guidance of staff, stick to one side of the second support plate and use the second support plate as a barrier to reduce the risk of being pushed and falling, ensure their own personal safety, and reduce the impact on evacuation efficiency. After the number of occupants is reduced, they can safely leave in the evacuation direction. BRIEF DESCRIPTION OF THE DRAWINGS

[0034] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0035] To simplify the drawings, only portions relevant to the invention are schematically depicted in each figure; they do not represent the actual structure of the product. Furthermore, to simplify the drawings and facilitate understanding, in some figures, only one component with the same structure or function is schematically depicted or labeled. In this document, "one" not only means "only one" but also "more than one," and "several" includes "two" and "more than two."

[0036] It should be noted that, unless otherwise specified or limited, the terms "mounted," "connected," and "connected" should be understood broadly. For example, they can refer to fixed, detachable, or integral connections; mechanical or electrical connections; direct or indirect connections through an intermediary; and internal communication between two components. Those skilled in the art will understand the specific meanings of these terms in the present invention based on specific circumstances.

[0037] In addition, in the description of the present application, the terms "first", "second", etc. are only used to distinguish the description and cannot be understood as indicating or implying relative importance.

[0038] like Figure 1-9As shown, a subway safety evacuation platform is provided with a support beam 101 and a handrail 102 on the wall 1, and the handrail 102 is located above the support beam 101, comprising: a first support plate 2, having a plurality of stems, horizontally laid on the support beam 101, the upper end of the first support plate 2 having a plurality of anti-slip protrusions 201, and the upper end of the first support plate 2 having at least one slide 202 arranged parallel to the evacuation direction; a hook 3, movably arranged on the handrail 102; a second support plate 4, vertically arranged and movably arranged on the handrail 102; The first support plate 2 is located above the side close to the wall 1, and the second support plate 4 is used to be horizontally laid on the upper end of the first support plate 2 or for being horizontally laid on the support beam 101. The second support plate 4 is detachably connected to the hook 3 and the hook 3 moves with the second support plate 4. The second support plate 4 has at least one limit plate 401 on the side away from the wall 1. When the second support plate 4 is horizontally laid on the upper end of the first support plate 2, the limit plate 401 slides in the slide 202 parallel to the evacuation direction.

[0039] When using, such as Figure 1 As shown, several first support plates 2 are laid side by side, supported by support beams 101, and secured above them with handrails 102. Second support plates 4, serving as backup, can be arranged parallel to the evacuation direction and spaced apart. In emergencies, they can be used to replace or cover first support plates 2, enabling rapid maintenance and repair. Furthermore, they act as barriers, providing a safe space for slower-moving individuals and reducing the risk of shoving. The second support plates 4 and first support plates 2 can have the same structure.

[0040] like Figure 2As shown, when the second support plate 4 is arranged vertically, it can be in an inclined state. The wall 1 in the tunnel is generally arc-shaped. The upper part of the second support plate 4 leans against or abuts against the wall 1. The second support plate 4 is heavy and can be stably maintained in an inclined state by gravity without tilting toward the side of the first support plate 2. The obtuse angle between the second support plate 4 and the first support plate 2 can be 100° (inclusive) to 115° (inclusive), maintaining a stable inclined state. When an emergency occurs and the second support plate 4 needs to be used, the staff can move the second support plate 4 nearby. The second support plate 4 is close to the wall 1. The staff pushes the second support plate 4 to move close to the wall 1, reducing space occupancy and enabling transportation in an emergency. The occupants can still evacuate (Note: the first support plate 2 that needs to be replaced or maintained is in a state of potential safety hazard. To ensure safety, maintenance is carried out, but evacuation is still possible at this time. The staff just needs to pay attention; if the first support plate 2 is completely unusable, the occupants on one side stop moving and cannot cross over, and the occupants who have passed can continue to move. The prepared second support plate 4 may be located on the side that stops moving or on the side that can continue to move). The hook 3 moves with the second support plate 4, which can improve the safety of movement and avoid the problem of the second support plate 4 tipping over.

[0041] When the first support plate 2 gradually develops small cracks or small damages, the overall structure is relatively complete. To improve safety and prevent passengers from stepping on it and falling, the second support plate 4 can be directly covered on the first support plate 2, and the anti-slip protrusions 201 abut against the second support plate 4. Figure 5-7 As shown, after the second support plate 4 is detached from the hook 3, the second support plate 4 is directly flipped down and placed on the first support plate 2, and the limit plate 401 is inserted into the slide 202 to prevent the second support plate 4 from sliding outward. After the complete second support plate 4 is covered, the whole is strengthened and there will be no collapse or falling problems. It is worth noting that during installation, the height difference between adjacent first support plates 2 is generally required to be no more than 3mm. The second support plate 4 covers the first support plate 2, that is, a small step appears. It serves as an emergency measure to prevent falling during emergency evacuation. It takes less maintenance time and can be used temporarily. The staff can provide lighting and reminders.

[0042] If the secondary hazards of the emergency are minor and there is ample time for evacuation, and the first support plate 2 is damaged, the first support plate 2 can be removed and replaced with the second support plate 4. The second support plate 4 is moved to a position adjacent to the damaged first support plate 2, flipped down and placed on the first support plate 2. At the same time, the damaged first support plate 2 is removed or cleaned. Then, the second support plate 4 can be slid onto the support beam 101 to complete the replacement.

[0043] like Figure 2As shown, the second support plate 4 is tilted against the wall 1, allowing slow-moving people to hide beside it, reducing the risk of falling due to shoving. Multiple sides of the second support plate 4 can be painted with a warning color. Even if a single person is standing, others may misjudge or move quickly, potentially pushing into the standing person and causing shoving. Compared to standing directly against the wall 1, the heavier second support plate 4 acts as a barrier, significantly reducing the amount of people crowding into the area, improving safety and reducing shoving.

[0044] The anti-skid protrusions 201 can be cylindrical or square in shape, and a plurality of anti-skid protrusions 201 are arranged in a square array, and a slideway 202 can be formed between two adjacent rows of anti-skid protrusions 201. The anti-skid protrusions 201 can also be arranged randomly, and the slideway 202 can be formed by grooving. Figure 7 As shown, two parallel, spaced-apart limiting plates 401 can also be provided. These plates 401 clamp onto the sides of a row of anti-slip protrusions 201 to provide position control. For clarity, the anti-slip protrusions 201 are exaggerated and do not represent their actual density or size. The evacuation direction is parallel to the axis of the handrail 102 shown in the diagram.

[0045] The hook 3 can be C-shaped, and the handrail 102 is fixed to the wall 1 through a bracket. The hook 3 can slide on the handrail 102. The inner diameter of the hook 3 is larger than the outer diameter of the handrail 102 and can pass through the bracket.

[0046] Furthermore, it also includes: a slide 5, which is sleeved on the lower part of the second support plate 4, and the slide 5 is slidably abutted against the upper end of the first support plate 2 on the side close to the wall 1.

[0047] The hook 3 is movably arranged relative to the second support plate, and there is an adjustment gap 2011 between the anti-slip protrusion 201 close to the wall 1 and the wall 1. The slide 5 slides away from or close to the wall 1 within the adjustment gap 2011. The lower part of the slide 5 has a limiting baffle 501 and a space-occupying baffle 502. The limiting baffle 501 is used to abut against the side of the anti-slip protrusion 201 close to the wall 1. The space-occupying baffle 502 is perpendicular to the limiting baffle 501. The space-occupying baffle 502 is used to be inserted between two adjacent anti-slip protrusions 201 in the evacuation direction.

[0048] When in use, the sliding seat 5 is detachably mounted on the lower portion of the second support plate 4, which can reduce the sliding resistance of the second support seat and protect the second support plate 4 to reduce damage during sliding.

[0049] like Figure 2-3As shown, the hook 3 is movably arranged relative to the second support plate, and can adapt to changes in the inclination angle of the second support plate. Moving the lower end of the second support plate and the slide 5 away from the wall 1 can enhance the blocking and occupying effect of the second support plate, increase the space occupied, provide better blocking and occupying space for slow-moving people, and improve safety. The second support plate 4 still tilts against the wall 1 and is stable. When equipment such as emergency escape lights are installed on the wall 1 below the handrail 102, the second support plate 4 can be moved by tilting and adjusting to avoid them.

[0050] like Figure 3 、 4 As shown, the slide 5 is away from the wall 1, and the limit baffle 501 abuts against the side of the anti-slip protrusion 201 close to the wall 1. The row of anti-slip protrusions 201 close to the wall 1 constitutes the travel limit of the slide 5, limiting the maximum space occupied by the second support plate 4 and preventing excessive encroachment on the evacuation channel. The occupying baffle 502 can be arranged perpendicular to the limit baffle 501, and multiple occupying baffles 502 can be provided. The occupying baffle 502 is inserted between two adjacent anti-slip protrusions 201 in the evacuation direction to limit the movement of the slide 5 in the evacuation direction, thereby preventing it from being pushed away by the crowd and providing greater stability. The anti-slip protrusions 201 can be a square array of rectangular arrays, which is convenient for use with the occupying baffle 502, the limit baffle 501 and the limit plate 401.

[0051] Furthermore, it also includes: a shell 6, which is slidably mounted on the upper part of the second support plate 4 parallel to the evacuation direction, and the shell 6 is movable relative to the upper part of the second support plate 4, and the shell 6 is hingedly mounted on the lower end of the hook 3.

[0052] The limiting plate 401 is located at the upper part of the second supporting plate 4 away from the wall 1 . A reinforcing plate 601 is provided on one side of the casing 6 . The reinforcing plate 601 has an avoidance groove 602 . One limiting plate 401 moves in the avoidance groove 602 .

[0053] During use, the hook 3 can move relative to the second support plate 4 through the housing 6, cooperating with the change in the tilt angle of the second support plate 4. When the slide 5 moves away from the wall 1, the obtuse angle between the second support plate 4 and the first support plate 2 increases, the upper part of the second support plate 4 descends, and the second support plate 4 moves downward relative to the housing 6.

[0054] like Figure 2As shown, the reinforcing plate 601 is on the side of the casing 6 away from the wall 1, and the avoidance groove 602 is covered on the limiting plate 401. The limiting plate 401 moves in the avoidance groove 602. When the second support plate 4 moves downward relative to the casing 6, the limiting plate 401 remains in the avoidance groove 602. When the second support plate 4 and the hook 3 move simultaneously, the limiting plate 401 is in the avoidance groove 602, which can prevent the limiting plate 401 from vertically disengaging from the limit groove, strengthen the casing 6 to limit the second support plate 4, prevent disengagement, and improve movement safety. The anti-dumping safety redundancy of the second support plate 4 allows the evacuation platform to prepare the second support plate 4, and in case of emergency, the second support plate 4 can be moved for emergency disposal with safety and reliability, which is feasible.

[0055] When the second support plate 4 needs to be laid down, the cover 6 can be removed by sliding it out parallel to the evacuation direction.

[0056] Furthermore, the second support plate 4 has an anti-skid column 402 on a side opposite to the wall 1 , and the sliding seat 5 has a socket 503 for plugging and connecting with the anti-skid column 402 .

[0057] When using, such as Figure 8 、 9 As shown, the slide 5 can have an L-shaped cross-section, half-wrapped under the second support plate 4. The insertion holes 503 are mounted on the anti-slip posts 402, allowing the slide 5 to be removably connected to the second support plate 4. During sliding, the second support plate 4 will not separate from the slide 5. When the second support plate 4 is laid down, the slide 5 can be pulled upward to complete the disassembly. If there is sufficient space between the second support plate and the wall 1, the slide 5 does not need to be removed.

[0058] Furthermore, it also includes: a connecting plate 7, and a connecting plate 7 is provided between every two adjacent support beams 101.

[0059] When using, such as Figure 5 As shown, when a damaged first support plate 2 is removed and a vacant space is created, the second support plate 4 is positioned above the adjacent first support plate 2. The second support plate 4 slides toward the vacant space, and the connecting plate 7 supports the second support plate 4, allowing it to slide until it fills the vacant space, making replacement and installation of the second support plate 4 more convenient and labor-saving. The provision of the connecting plate 7 also enhances the strength and stability of the adjacent support beams 101.

[0060] Furthermore, the support beam 101 has a positioning block 1011 , and both the first support plate 2 and the second support plate 4 have a positioning groove 403 that is plugged into and fits with the positioning block 1011 .

[0061] During use, the first support plate 2 or the second support plate 4 can be stably installed through the plug-in cooperation between the positioning groove 403 and the positioning block 1011 to prevent it from slipping.

[0062] It will be understood that the present invention is described by way of some embodiments, and it will be appreciated by those skilled in the art that various changes or equivalent substitutions may be made to these features and embodiments without departing from the spirit and scope of the present invention. In addition, under the teachings of the present invention, these features and embodiments may be modified to adapt to specific circumstances and materials without departing from the spirit and scope of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed herein, and all embodiments falling within the scope of the claims of this application are intended to be protected by the present invention.
