Description

Technical Field

[0001] This invention relates to the field of subway tunnel rescue equipment technology, and in particular to an evacuation platform for subway tunnels. Background Technology

[0002] Subways are high-speed, high-capacity, electrically powered rail transit systems built in cities. Lines located in the city center are mostly located in underground tunnels. Tunnels are engineering structures buried in the earth's strata, and evacuation platforms are installed on the inner walls of the tunnels, providing safe spaces for passengers to take emergency shelter.

[0003] The existing evacuation platform consists of supports, platforms, and support rods. Multiple platforms are installed, all positioned on the same horizontal line. Each platform is horizontally placed, and the supports are fixedly connected to the platforms and the tunnel. The support rods are bolted to the tunnel wall and the platform at both ends, respectively. In the event of an emergency in the subway, evacuees stand on the upper surface of the platforms, and the evacuation platform, formed by the interconnected platforms, provides ample escape space.

[0004] Regarding the aforementioned technologies, the inventors believe that the following drawbacks exist: the evacuation platform fixed in the above manner is cumbersome to assemble and disassemble, consumes a lot of manpower and time, and increases the difficulty of later maintenance, reducing the construction efficiency of evacuation platforms for subway tunnels; the platform is too narrow, and when the evacuated personnel are densely packed, some people may slip off the platform due to crowding and get injured. If the platform is widened, the distance between the end of the platform away from the support and the support will be too large, causing the platform to shake. In addition, the environment inside the tunnel is humid, and the bolts are prone to corrosion, which may lead to the platform breaking, reducing the safety of the platform. Summary of the Invention

[0005] To address the aforementioned shortcomings in the existing technology, this invention aims to provide an evacuation platform for subway tunnels, thereby improving the construction efficiency and safety of the evacuation platform.

[0006] To achieve the above objectives, the technical solution adopted by the present invention is as follows: it includes supports, platforms, and support rods for connecting with the tunnel, with multiple supports and platforms provided, and each platform being fixed between two adjacent supports; the top end of the support rod is provided with a connecting component for connecting the support and the support rod, and / or the bottom end of the support rod is provided with a connecting component for connecting the support rod and the tunnel.

[0007] As a limitation of the present invention, the connecting assembly includes a connecting cylinder and a connecting column. The connecting cylinder is fixedly installed at the bottom end of the support, the connecting cylinder and the connecting column are plugged into each other, and the connecting column is rotatably connected to the support rod.

[0008] As another limitation of the present invention, the connecting column is composed of at least two connecting parts spliced ​​together. Each connecting part includes a fixedly connected plug and a shaft cylinder, with the plug inserted into the connecting cylinder. A connecting shaft is fixedly mounted on the support rod, and a rotating groove is provided on the shaft cylinder to facilitate the rotation of the support rod around the connecting shaft.

[0009] As a further limitation of the present invention, a limiting plate for restricting the lateral movement of the platform is fixed at the end of the support away from the connection position with the tunnel, and a limiting component for fixing and restricting the longitudinal movement of the platform is provided between adjacent platforms.

[0010] As a further limitation of the present invention, the limiting component includes a pressure plate, a plug-in block and a limiting block. The two ends of the plug-in block are fixedly connected to the pressure plate and the limiting block. The side wall of the support is provided with a plug-in hole. The plug-in block is slidably inserted into the plug-in hole. The upper surface of the limiting block abuts against the bottom surface of the support. The bottom surface of the pressure plate abuts against the upper surface of the platform.

[0011] As a third limitation of the present invention, a limiting post is fixed on the upper surface of the support at both ends of the tunnel longitudinal direction, and the side wall of the limiting post abuts against the platform.

[0012] As a further limitation of the present invention, the cross-sectional area of ​​the limiting block gradually increases from the end away from the pressure plate to the end closer to the pressure plate; the upper surface of the pressure plate is an arc-shaped structure; and a reinforcing rib is provided between the support and the inner wall of the tunnel, and the reinforcing rib is fixedly connected to the support.

[0013] As another limitation of the present invention, a protrusion is provided on the upper surface of the platform, and the protrusion is fixedly connected to the platform.

[0014] As another limitation of the present invention, a raised strip is provided on the upper surface of the platform, the raised strip is fixedly connected to the platform, and the raised strip is made of fluorescent material.

[0015] As another limitation of the present invention, an adjustment gap is provided between adjacent platform plates.

[0016] By adopting the above-described technical solution, the beneficial effects achieved by this invention compared to the prior art are as follows:

[0017] (1) The support rod and the support of the present invention are connected by a connecting component, which facilitates installation and improves the construction efficiency of the evacuation platform. The detachable support rod and support avoid safety accidents caused by corrosion of bolts in humid environments, thus improving the safety of the evacuation platform for subway tunnels.

[0018] (2) The connection column and the connection cylinder of the present invention are inserted into each other, which makes the connection component easy to install. The support rod and the connection column are rotatably connected, which makes the support rod adjustable and adaptable to various different installation environments, thus improving the applicability of the connection component.

[0019] (3) The plug-in column of the present invention is located inside the connecting cylinder, and the end face of the shaft cylinder connected to the plug-in column abuts against the connecting cylinder. When the platform is subjected to gravity, the platform will slightly dent downwards. At this time, the rotating shaft will drive the support rod to rotate slightly to adapt to the new equilibrium state. At this time, the connecting cylinder will be more tightly abutted against the shaft cylinder due to gravity, which improves the stability of the platform and thus improves the safety of the evacuation platform.

[0020] (4) The limiting component and the limiting plate of the present invention are used together to assemble the platform and the support, so that the position of the platform is fixed, the installation is simple and the safety of the evacuation platform is improved.

[0021] (5) After the adjacent platform is placed on the upper surface of the support, the limiting block drives the plug block to be inserted into the plug hole until the limiting block is close to the side wall of the pressure plate and abuts against the lower surface of the support. At this time, the lower surface of the pressure plate abuts against the upper surface of the platform. The limiting component is used to assemble the platform and the support, making the platform easy to disassemble, easy to disassemble and repair, thereby improving the construction efficiency of the evacuation platform for subway tunnels.

[0022] (6) The limiting columns of the present invention reinforce the platform position from both ends of the tunnel length direction to prevent the platform from shaking and improve the stability of the evacuation platform.

[0023] (7) The inclined structure of the limiting block of the present invention provides a guiding function for the insertion, which improves the ease of use of the limiting block and facilitates installation, thereby improving the construction efficiency of the evacuation platform for subway tunnels; the upper surface of the arc-shaped pressure plate is convenient for users to walk on, and it is not easy to fall due to the protrusion of the pressure plate, which reduces the possibility of user injury and thus improves the safety of the evacuation platform for subway tunnels; the reinforcing ribs are used in conjunction with the support to improve the load-bearing capacity of the support, improve the stability of the platform, and thus improve the stability of the evacuation platform for subway tunnels.

[0024] (8) The protrusions of the present invention are used in conjunction with the platform to increase the friction between the platform and the user, making it less likely for the user to slip and get injured, thus improving the safety of the platform and the safety of the evacuation platform in the subway tunnel.

[0025] (9) Since the evacuation platform is used in a dark environment, the fluorescent material protrusions provide users with a way to determine their direction of movement, which improves the ease of use of the evacuation platform in the subway tunnel.

[0026] (10) Since the subway tunnel has an arc-shaped structure, the adjustment joint provides adjustment space for fine adjustment between the platform, which facilitates installation and improves the ease of use of the platform. Attached Figure Description

[0032] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustrative purposes only and are not intended to limit the scope of the invention.

[0033] Example 1: An evacuation platform for a subway tunnel

[0034] like Figures 1 to 3 As shown, this embodiment includes a support 1, a platform 2, and a support rod 3.

[0035] refer to Figure 1 Multiple sets of supports 1 and platforms 2 are provided. Each platform 2 is fixedly installed between two adjacent supports 1. The platforms 2 are placed horizontally, and the upper surfaces of each platform 2 are located in the same plane. One end of the support 1 is fixedly connected to the inner wall of the tunnel. To improve the construction efficiency during the installation of supports 1 and platforms 2, a limiting component 6 is provided between the support 1 and the platform 2. The top end of the support rod 3 is provided with a connecting component 5 for connecting the support 1 and the support rod 3, and / or the bottom end of the support rod 3 is provided with a connecting component 5 for connecting the support rod 3 and the tunnel; that is, a connecting component 5 can be provided at the top end of the support rod 3 and a connecting component 5 can be provided at the bottom end of the support rod 3. In this embodiment, both the top and bottom ends of the support rod 3 are provided with connecting components 5.

[0036] refer to Figure 1 and Figure 2The limiting component 6 includes a pressure plate 61, a plug-in block 62, and a limiting block 63. Both the plug-in block 62 and the limiting block 63 are block-shaped structures, and the two ends of the plug-in block 62 are fixedly connected to the limiting block 63 and the pressure plate 61, respectively. A plug-in hole 11 is provided on the side wall of the support 1, and the plug-in block 62 is slidably inserted into the plug-in hole 11. The upper surface of the limiting block 63 abuts against the bottom surface of the support 1, and the bottom surface of the pressure plate 61 abuts against the upper surface of the platform 2. The pressure plate 61 is a strip-shaped structure, and its upper surface has an arc-shaped structure to facilitate smooth passage for the user. The cross-sectional area of ​​the limiting block 63 gradually increases from the end furthest from the pressure plate 61 to the end closest to the pressure plate 61. To ensure the stability of the platform 2 during use, a limiting plate 4 is provided at the end of the support 1 furthest from the tunnel wall, and the limiting plate 4 is vertically fixedly connected to the support 1.

[0037] refer to Figure 1 and Figure 3 To improve the stability of support 1, reinforcing ribs 8 are installed between support 1 and the tunnel wall, and the reinforcing ribs 8 are fixedly connected to support 1. Protrusions 9 are fixedly provided on the upper surface of platform 2, increasing the friction between the user and platform 2 and reducing the possibility of slipping. Due to the dim lighting inside the tunnel, raised strips 10 are fixedly provided on the upper surface of platform 2, and these raised strips 10 are made of fluorescent material, providing accurate direction for evacuated personnel to leave the tunnel, thus improving the ease of use of platform 2. Because the tunnel contains curved structures, adjusting joints 21 are provided between adjacent platform 2, allowing platform 2 to be assembled to adapt to tunnels of different curvatures, thus improving the adaptability of platform 2.

[0038] refer to Figure 3 The connecting component 5 includes a connecting cylinder 51 and a connecting post 52. The connecting post 52 is a split structure and is formed by splicing at least two connecting parts. In this embodiment, the connecting post 52 is formed by splicing two connecting parts. Each connecting part includes a fixedly connected insertion post 521 and a shaft cylinder 522. The insertion post 521 is inserted into the connecting cylinder 51. The end face of the insertion post 521 is fixedly connected to the end face of the shaft cylinder 522. A connecting shaft 31 is fixedly mounted on the support rod 3. The side wall of the connecting shaft 31 is fixedly connected to the end face of the support rod 3, and the connecting shaft 31 is slidably inserted into the shaft cylinder 522. The side wall of the shaft cylinder 522 is provided with a rotating groove 5221 to facilitate the rotation of the support rod 3 around the connecting shaft 31. The insertion post 521 is slidably inserted into the connecting cylinder 51.

[0039] The connection structure between the support rod 3 and the tunnel is the same as that of the connecting assembly 5 described above. The difference is that one end of the connecting cylinder 51 in the connecting assembly 5 between the support 1 and the support rod 3 is fixedly connected to the bottom surface of the support 1, and the connecting shaft 31 at the top of the support rod 3 is used to fix the connecting cylinder 51 in the connecting assembly 5 between the support rod 3 and the tunnel to the tunnel. This greatly reduces the use of bolts during installation, avoids safety accidents caused by bolt corrosion, and improves the safety of the evacuation platform.

[0040] Work process

[0041] When using this embodiment, the support 1 is first fixedly connected to the inner wall of the tunnel. The platform 2 is then placed sequentially by adjusting the adjusting joint 21. The limiting block 63 drives the insertion block 62 to slide into the insertion hole 11 until the upper surface of the limiting block 63 abuts against the bottom surface of the support 1. At this time, the lower surface of the pressure plate 61 abuts against the upper surface of the platform 2. The connecting shaft 31 is rotated so that the shaft cylinder 522 drives the insertion column 521 to rotate around the axis of the connecting shaft 31 until the insertion column 521 is inserted into the connecting cylinder 51. At this time, the support column is installed. The operation is simple and the structure is stable, which improves the construction efficiency and safety of the evacuation platform for subway tunnels.
