Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of rail transit, in particular to a retractable emergency evacuation platform for a rail transit system. BACKGROUND

[0002] As a widely used public transport mode in modern cities, the rail transit system has the advantages of strong carrying capacity and high safety, and is the preferred means of transportation for the majority of travelers. The safety of the rail transit system is directly related to the vital interests of the general public, so improving the safety of the rail transit system has become the focus of industry research.

[0003] In order to improve the safety of the rail transit system, the industry usually sets up an evacuation platform in a tunnel or on a viaduct. The existing evacuation platform is made of concrete or composite material steps, which are supported by a support and fixed on the tunnel wall or the bridge edge of the viaduct, and the height is flush with the floor of the train carriage. In the event of vehicle failure, power supply system failure, fire, flood, terrorist attack and other accidents during train operation, passengers can quickly evacuate through the evacuation platform to ensure the safety of passengers and their property.

[0004] However, in the existing rail transit system, the actual evacuation platform is not set up at the turnout area of the station after the tunnel or viaduct ends, and due to the limitation of the space structure, the evacuation platform cannot be continuous in the interval of the civil air defense door, the flood prevention door, the distribution line and other sections. It needs to be disconnected and set up an evacuation stairway down to the concrete surface of the track bed to ensure the continuity of personnel evacuation through the concrete surface of the track bed. That is, the existing evacuation platform forms a sunken low-lying area in the case of limited space, which can meet the evacuation needs in ordinary cases, but in the event of a flood and other accidents, the area of the concrete surface of the track bed will be flooded, that is, the sunken low-lying area of the evacuation platform will be flooded, which will interfere with the evacuation of passengers and cause the problem of delayed personnel evacuation. In addition, the disconnected part of the evacuation platform in most of the existing rail transit systems is installed with a large number of cables, cable supports, distribution boxes and other facilities, which have many limitations in the height direction, resulting in the problem of insufficient installation space for the traditional platform plate type evacuation platform, and there is also insufficient space to directly turn the platform plate up and down for storage, so it is difficult to have a suitable evacuation platform structure to realize the continuity of the evacuation platform.

Embodiment

[0031] In order to make the technical means, creative features, purposes and effects of the present application easy to understand, the following embodiments are combined with the accompanying drawings to illustrate the present application. Figure 1 to the accompanying drawings Figure 8 The technical solutions provided by the present application are described in detail below, but the following content is not a limitation of the present application.

[0032] Figure 1 is a structural diagram of an embodiment of the retractable emergency evacuation platform for a rail transit system in use; Figure 2 is a structural diagram of an embodiment of the retractable emergency evacuation platform for a rail transit system when not in use. Figure 1 and Figure 2 As shown in the drawings, the retractable emergency evacuation platform for a rail transit system provided by the present embodiment comprises: a plurality of rotating skeletons 1, a plurality of rolling platform plates 3, and a plurality of binding pieces 4.

[0033] Specifically, the plurality of rotating skeletons 1 are arranged on the tunnel wall surface 2 to be superimposed along the length direction of the tunnel, i.e. the rotating skeletons 1 are installed at the tunnel where the existing evacuation platform is to be superimposed, which provides conditions for setting a retractable evacuation platform at this place subsequently. Moreover, the rotating direction of the rotating skeleton 1 is the length direction of the tunnel in the horizontal plane, i.e. the movement space of the rotating skeleton 1 is only in the horizontal plane and is not affected by the height direction of the tunnel, effectively avoiding the influence of the cable, cable bracket 13, distribution box and other facilities in the tunnel, and also avoiding the influence of the cable, cable bracket 13, distribution box and other facilities in the tunnel on the overturning of the rotating skeleton 1 to realize retraction. At the same time, the plurality of rotating skeletons 1 are arranged at the disconnected place of the original evacuation platform in the tunnel, which provides conditions for supplementing the disconnected place of the original evacuation platform by the retractable emergency evacuation platform provided by the present embodiment subsequently, to realize the continuity of the evacuation platform.

[0034] Specifically, the several coiling platform plates 3 are arranged at the disconnected position of the original evacuation platform in the tunnel, that is, the arrangement position of the coiling platform plate 3 in the tunnel is the same as the arrangement position of the rotating frame 1 in the tunnel, so as to form a new evacuation platform with the coiling platform plate 3 and the rotating frame 1 to supplement the disconnected position of the original evacuation platform. In addition, the several coiling platform plates 3 are laid on the several rotating frames 1 after being turned over, and the coiling platform plates 3 are supported by the rotating frames 1, so as to form a collapsible emergency evacuation platform. In addition, the two ends of each coiling platform plate 3 correspond to a rotating frame 1, that is, the two ends of each coiling platform plate 3 are supported by the rotating frame 1. In addition, one side of each coiling platform plate 3 is installed on the tunnel wall 2 at the corresponding position, that is, one side of the coiling platform plate 3 is installed on the tunnel wall 2 where the rotating frame 1 is installed. At this time, when the coiling platform is coiled, the coiling platform plate 3 is coiled to one side of the tunnel wall 2, so as to realize the shrinkage of the coiling platform plate 3, occupy a very small space in the height direction of the tunnel, and have a smaller influence on other facilities in the tunnel compared with the existing structure of directly turning up and down the whole plate, and have higher adaptability. In addition, when the coiling platform plate 3 is unfolded and laid on the rotating frame 1, the plate surface of the coiling platform plate 3 is flush with the surface of the original evacuation platform, so as to ensure that the surface of the collapsible emergency evacuation platform supplemented in the disconnected position of the original evacuation platform is consistent with the overall surface height of the original evacuation platform, ensure the flatness of the evacuation platform, and have higher safety, which is beneficial to emergency evacuation.

[0035] Specifically, each coiling platform plate 3 corresponds to at least one binding piece 4, preferably two binding pieces 4 corresponding to one coiling platform plate 3, and the two binding pieces 4 are respectively located at the two ends of the corresponding coiling platform. At this time, the binding piece 4 is installed on the tunnel wall 2 where the corresponding coiling platform plate 3 is installed, and the binding piece 4 binds the coiling platform plate 3 when the coiling platform plate 3 is coiled, that is, the coiling platform plate 3 after being coiled can be bound by the binding piece 4, so as to prevent the coiling platform after being coiled from being scattered, and the structure design is more reasonable.

[0036] Figure 3 The installation schematic view of the auxiliary support and the rotating frame in one state of a preferred embodiment of the present application is shown in the figure. Figure 4 The installation schematic view of the auxiliary support and the rotating frame in another state of a preferred embodiment of the present application is shown in the figure. Figures 1 to 4As shown, the rotating frame 1 is further provided with a plurality of auxiliary support members 5, and each rotating frame 1 corresponds to at least one auxiliary support member 5, so that each rotating frame 1 can be supported by the corresponding auxiliary support member 5, thereby improving the carrying capacity of the rotating frame 1. Meanwhile, one end of the auxiliary support member 5 is connected to the end of the rotating frame 1 away from the tunnel wall 2, that is, the auxiliary support member 5 can support the far wall end of the rotating frame 1, and at the same time, the auxiliary support member 5 can also be turned on the rotating frame 1, thereby providing conditions for the subsequent unfolding or folding of the auxiliary support member 5. In addition, the other end of the auxiliary support member 5 is selectively connected to the tunnel wall 2 where the corresponding rotating frame 1 is located, that is, when the auxiliary support member 5 is needed to support the rotating frame 1, the other end of the auxiliary support member 5 is connected to the tunnel wall 2, and when the rotating frame 1 needs to be turned, the auxiliary support member 5 is detached from the tunnel wall 2, thereby ensuring the normal turning of the rotating frame 1 and making the structure design more reasonable.

[0037] More specifically, each auxiliary support member 5 includes a hinge block 51, a connecting rod 52, and a support seat 53. At this time, the support seat 53 is fixedly arranged on the tunnel wall 2 below the corresponding rotating frame 1, thereby providing conditions for the subsequent selective connection of the auxiliary support member 5 to the tunnel wall 2. In addition, the hinge block 51 is fixedly installed on the end of the rotating frame 1 away from the connecting tunnel wall 2, thereby realizing the stable connection of the hinge block 51 and the rotating frame 1 and ensuring that the auxiliary support member 5 provides stable support to the rotating frame 1. In addition, one end of the connecting rod 52 is hingedly connected to the hinge block 51, that is, the hinge block 51 serves as a connecting structure between the connecting rod 52 and the rotating frame 1, thereby realizing the connection between the connecting rod 52 and the rotating frame 1 and also allowing the connecting rod 52 to be deflected on the rotating frame 1, thereby providing conditions for the subsequent folding of the connecting rod 52. In addition, the other end of the connecting rod 52 is selectively connected to or separated from the support seat 53, that is, when the other end of the connecting rod 52 is connected to the support seat 53, the connecting rod 52 can support the rotating frame 1 by means of the support seat 53 installed on the tunnel wall 2, and when the other end of the connecting rod 52 is separated from the support seat 53, the connecting rod 52 is not connected to the tunnel wall 2, thereby allowing the connecting rod 52 to move with the rotating frame 1, thereby realizing the folding of the rotating frame 1.

[0038] More specifically, the support seat 53 in the auxiliary support 5 is provided with a quick-release connecting part 531, which is connected with the connecting part to realize quick connection or separation. At this time, the quick-release connecting part 531 includes two clamping plates 5311 arranged in parallel and spaced apart, and the two clamping plates 5311 are arranged along the height direction of the tunnel, so that when the connecting rod 52 is connected with the quick-release connecting part 531 later, the connecting rod 52 can approach along the height direction of the clamping plate 5311, thereby adapting to the posture change of the unfolded rotating framework 1, and the connection is more convenient. Meanwhile, a connecting hole is formed through each clamping plate 5311, and the connecting holes on the two clamping plates 5311 are coaxially arranged in the length direction of the tunnel, so that the arrangement direction of the connecting holes is perpendicular to the direction in which the connecting rod 52 approaches the clamping plate 5311, thereby providing conditions for limiting the end of the connecting rod 52 in the quick-release connecting part 531 formed by the clamping plate 5311 through the connecting hole later. In addition, a through insertion hole 521 is formed in the other end of the connecting rod 52, and a pin shaft 532 is arranged to pass through the two connecting holes, and the end of the pin shaft 532 is provided with a catch pin 533. When the connecting rod 52 is connected with the support seat 53, the end of the connecting rod 52 extends into the space between the two clamping plates 5311, and when the pin shaft 532 passes through the connecting hole, the pin shaft 532 also passes through the insertion hole 521, so that the connecting rod 52 is limited on the support seat 53 by the pin shaft 532, thereby realizing the connection between the connecting rod 52 and the tunnel wall 2, and meeting the support requirement. When the connecting rod 52 needs to be separated from the quick-release connecting part 531, only the pin shaft 532 needs to be pulled out, and the operation is more convenient and the structure design is more reasonable. It is worth pointing out that the catch pin 533 arranged at the end of the pin shaft 532 can prevent the pin shaft 532 from falling out of the connecting hole, and the reliability is higher.

[0039] More specifically, in order to facilitate the storage of the connecting rod 52, at this time, the auxiliary support 5 further includes an end auxiliary fixing part, and the end auxiliary fixing part is arranged in a hook structure, and the end auxiliary fixing part is installed on the rotating framework 1. When the connecting rod 52 is separated from the support seat 53 and the rotating framework 1 needs to be deflected, the other end of the connecting rod 52 can be hooked by the end auxiliary fixing part after being separated from the support seat 53, thereby realizing the storage of the other end of the connecting rod 52, and the storage effect is better and the safety guarantee is higher. Meanwhile, the end auxiliary fixing part in a hook structure facilitates the storage of the connecting rod 52.

[0040] More specifically, each rotating frame 1 includes a fixed base 11, a rotating shaft 12, and a support 13. The fixed base 11 is fixedly installed on the tunnel wall 2. At the same time, one end of the support 13 is hinged to the fixed base 11 via the rotating shaft 12, allowing the support 13 to swing on the fixed base 11 via the rotating shaft 12. Furthermore, the axis of the rotating shaft 12 is along the height direction of the tunnel, so that the swing direction of the support 13 is circumferential to the rotating shaft 12, that is, swinging along the length direction of the tunnel in the horizontal plane. This avoids occupying space in the height direction of the tunnel, resulting in a more reasonable structural design.

[0041] More specifically, the support 13 has several spaced stiffening plates 14 on its side and along its length. Preferably, the support 13 is made of I-beams, and the stiffening plates 14 are placed on both sides of the I-beams. This means that the structural strength and load-bearing capacity of the support 13 are improved by the stiffening plates 14, making it suitable for emergency evacuation platforms.

[0042] Figure 5 This is a schematic diagram of the installation of the winding platform plate during unfolding according to a preferred embodiment of the present invention; Figure 6 This is a schematic diagram illustrating the installation of the winding platform plate during winding, according to a preferred embodiment of the present invention. Figure 1 , Figure 2 as well as Figure 5 and Figure 6 As shown, each winding platform plate 3 includes several support rods 31, several hinges 32, and a side connecting seat 33. The support rods 31 in the same winding platform plate 3 are arranged parallel and spaced apart, meaning they are arranged side-by-side. Furthermore, the support rods 31 are all arranged along the length of the tunnel, so that the winding platform plate 3 composed of the support rods 31 is also arranged along the length of the tunnel, thus meeting the installation requirements of the emergency evacuation platform. A hinge 32 is provided between adjacent support rods 31, allowing adjacent support rods 31 to rotate relative to each other, thereby enabling the winding and unfolding of the winding platform plate 3 composed of the support rods 31. A side connecting seat 33 is installed on the outermost support rod 31 of the same winding platform plate 3. A hinge 32 is provided between the side connecting seat 33 and the support rod 31, allowing the winding platform plate 3 composed of the support rods 31 to flip on the side connecting seat 33, meeting the winding and unfolding requirements of the winding platform plate 3. Furthermore, the side connecting seat 33 is fixedly installed on the tunnel wall 2, which enables the winding platform plate 3 to be flipped on the tunnel wall 2 and also enables the winding platform plate 3 to be installed on the tunnel wall 2, thus improving the installation stability and reliability of the winding platform plate 3 and providing higher safety assurance.

[0043] In addition, this embodiment also provides a structure of a winding platform plate composed of flat plates. Figure 7This is a schematic diagram illustrating the installation of another winding platform plate during winding, according to a preferred embodiment of the present invention. Figure 7 As shown, each winding platform 3 includes several flat plates 35, several hinges 32, and side connecting seats 33. The flat plates 35 of the same winding platform 3 are arranged parallel and spaced apart, meaning they are arranged side-by-side. Each flat plate 35 is arranged along the length of the tunnel, ensuring that the winding platform 3 composed of these flat plates also follows the length of the tunnel, thus meeting the installation requirements of the emergency evacuation platform. Furthermore, hinges 32 are provided between adjacent flat plates 35, allowing them to rotate relative to each other. This enables the winding platform 3 composed of these flat plates to be folded up or unfolded. Since the flat plates 35 are wider than the support rods 31, fewer flat plates 35 are needed to assemble a winding platform 3 of the same area, reducing the number of folds during folding up or unfolding, resulting in higher folding efficiency and greater ease of use. Similarly, a side connecting seat 33 is also installed on the outermost flat plate 35 of the same winding platform plate 3. A hinge 32 is provided between the side connecting seat 33 and the flat plate 35, allowing the winding platform plate 3, composed of several flat plates 35, to rotate on the side connecting seat 33, meeting the requirements for retracting and unfolding the winding platform plate 3. Furthermore, the side connecting seat 33 is fixedly installed on the tunnel wall 2. This means that the rotation of the winding platform plate 3 on the tunnel wall 2 is achieved through the side connecting seat 33, and the installation of the winding platform plate 3 on the tunnel wall 2 is also realized, improving the installation stability and reliability of the winding platform plate 3 and enhancing safety.

[0044] More specifically, a limiting piece 34 is provided on the outermost support rod 31 or plate 35 of the same retractable platform plate 3. At the same time, the limiting piece 34 is set at both ends of the support rod 31 or plate 35. That is, when the retractable platform plate 3 is unfolded and laid on the rotating frame 1, the limiting piece 34 is located beside the rotating frame 1. At the same time, the limiting piece 34 abuts against the rotating frame 1. That is, when the retractable platform plate 3 is laid on the rotating frame 1, one side of the retractable platform plate 3 is connected to the tunnel wall 2 through the side connecting seat 33, and the other side of the retractable platform plate 3 is mutually limited with the rotating frame 1 through the limiting piece 34. This achieves stable installation of the retractable platform plate 3 and further improves the safety of the emergency evacuation platform.

[0045] Figure 8 This is a schematic diagram illustrating the installation of a binding member according to a preferred embodiment of the present invention. Figure 2 and Figure 8As shown, each binding part 4 for bundling the rolled-up winding platform plate 3 comprises a limiting seat 41, a rope 42 and a hook 43. At this time, the limiting seat 41 is fixedly installed on the tunnel wall 2 and is located above the winding platform, thereby providing a condition for suspending the rolled-up winding platform plate 3 on the tunnel wall 2 after being bundled. In addition, the hook 43 is installed on the limiting seat 41, one end of the rope 42 is connected to the limiting seat 41 or the hook 43, and the other end of the rope 42 is connected to or separated from the hook 43. When the other end of the rope 42 is connected to the hook 43, both ends of the rope 42 are limited, so that the rope 42 forms a loop structure, thereby realizing the bundling of the rolled-up winding platform plate 3. When the other end of the rope 42 is separated from the hook 43, the other end of the rope 42 is in a free state and does not bind the winding platform plate 3, thereby facilitating the unfolding of the rolled-up winding platform plate 3 and making the structure more reasonable. Preferably, the rope 42 is a steel wire rope, which has high structural strength and high carrying capacity. Meanwhile, the hook 43 can be a hook with anti-dropping function on the market, which has higher safety protection.

[0046] As a further preferred embodiment, an end hole 131 is formed at the end of the support 13 of each rotating framework 1 away from the fixed base 11, and a draw hook 6 is also installed on the tunnel wall 2 at a position corresponding to the retracted rotating framework 1. In this way, when the rail transit is normally operated, the end hole 131 of the support 13 can be pulled by the draw hook 6, thereby preventing the rotating framework 1 from being mistakenly unfolded, and the safety protection is higher.

[0047] It is worth noting that, when the retractable emergency evacuation platform provided in the present embodiment is switched from the retracted state to the unfolded state, the unfolding process of the rotating framework 1 only needs to manually remove the draw hook 6 from the end hole 131 and then push the support 13 in the horizontal direction. The unfolding process of the winding platform plate 3 only needs to manually remove one end of the rope 42 from the hook 43 and then turn it up. In addition, after the support 13 in the rotating framework 1 is unfolded, one end of the connecting rod 52 can be manually connected to the support seat 53. At this time, the end of the connecting rod 52 provided with the insertion hole 521 is inserted into the gap between the two clamping plates 5311 of the quick-release connecting part 531, the pin shaft 532 is manually inserted through the insertion hole 521 and the connecting hole in the clamping plate 5311, and the catch 533 is inserted into the end of the pin shaft 532, thereby realizing the manual installation of the auxiliary support 5. That is, when the retractable emergency evacuation platform provided in the present embodiment is switched from the retracted state to the unfolded state, all the operations involved in the process can be completed by hand without the aid of any auxiliary tools, which is more suitable for use in dangerous situations and also conforms to the actual situation that passengers rarely carry tools with them, and the structure is more reasonable.

[0048] The track traffic system retractable emergency evacuation platform provided by the embodiment comprises a plurality of rotating frames 1, a plurality of retractable platform plates 3 and a plurality of binding parts 4; the rotating frames 1 are arranged in the tunnel in the length direction of the horizontal plane at the disconnected part of the original evacuation platform in the tunnel, the retractable platform plates 3 are laid on the rotating frames 1 in the length direction of the tunnel, and the binding part 4 corresponding to each retractable platform plate 3 is arranged on the tunnel wall 2; in case of an unexpected situation, the rotating frame 1 and the retractable platform plate 3 are both unfolded to supplement the disconnected part of the original evacuation platform, ensuring the continuity and integrity of the evacuation platform and providing higher safety protection; when there is no unexpected situation, the rotating frame 1 and the retractable platform plate 3 can be retracted, the retractable platform plate 3 is bound by the binding part 4, and the storage is more stable and reliable; at the same time, the rotating direction of the rotating frame 1 is the length direction of the horizontal plane in the tunnel, effectively avoiding the problem of occupying the space in the height direction of the tunnel, thereby avoiding the influence on the cables and other equipment in the tunnel, and also avoiding the problem of needing a large enough space to directly turn the platform plate up and down for storage, meeting the folding requirement and having higher structural adaptability.

[0049] The above is only the preferred embodiment of the present application, and does not limit the implementation and protection scope of the present application.
