Description

Technical Field

[0001] This utility model relates to the technical field of emergency avoidance devices for bridge sound barrier sections, and in particular to an emergency avoidance platform for bridge sound barrier sections. Background Technology

[0002] In highway operation, due to the special structure of bridge sections (such as enclosed space, limited load-bearing capacity, and the presence of sound barriers or bridge railings on both sides), people often find themselves in a predicament of "no evacuation route and no space to avoid danger" after a traffic accident. Their emergency escape capabilities have long been a shortcoming. Among the existing emergency facilities, the emergency lanes of bridge sound barrier sections are often compressed or eliminated due to the limitation of bridge width, making it impossible for people on them to quickly escape from their high-risk environment after an accident occurs nearby.

[0003] In existing technologies, emergency escape facilities (such as emergency lanes and emergency parking areas) on ordinary road sections are difficult to directly adapt to bridge sound barrier sections. On highway bridge sound barrier sections, due to the narrow space between the sound barrier and the lane and the fact that the sides are mostly enclosed structures, in the event of a multi-vehicle collision or loss of vehicle control, trapped personnel lack a dedicated space to move them away from the lane. This raises the question of how to quickly transfer personnel from the accident scene to a safe area completely free from the threat of traffic. This significantly increases the risk of secondary injury, especially in some long-distance sound barrier sections where there is no escape space. Current emergency measures for this section mainly focus on bridge surface warnings or temporary parking.

[0004] Therefore, given the special environment of bridge sound barrier sections, there is an urgent need for an emergency refuge platform that can utilize limited space, adapt to bridge structures, and have basic protective functions to solve the problems of lack of refuge space, poor facility adaptability, and insufficient protection in existing technologies for bridge sound barrier sections. Utility Model Content

[0005] To overcome the above deficiencies, this utility model provides an emergency escape platform for bridge sound barrier sections, aiming to improve the existing technology on how to quickly transfer personnel from the accident scene to a safe area completely free from the threat of traffic when a multi-vehicle chain-reaction accident or vehicle loss of control occurs on a bridge sound barrier section.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: The bridge includes a bridge body, with piers connected to the bottom of the bridge body, sound barrier panels installed on the bridge body, and safety doors installed on the sound barrier panels. It also includes: The protective components are installed on the outside of the sound barrier panels to provide shelter for people in case of danger on the bridge and to protect the people taking shelter. The protective components include a safety platform located outside the safety gate, a connecting plate connected to the safety platform, a supporting toothed plate slidably connected to the connecting plate, and a safety fence connected to the safety platform. The lifting assembly, mounted on the connecting plate, is used to lift the refuge platform, allowing personnel on it to be transferred to a safe area. The safety drive component, located on the connecting plate, is used to safely drive the lifting component, enabling the safety platform to rise and fall stably.

[0007] As a further description of the above technical solution: The protective assembly also includes a stabilizing frame connected to the bottom of the supporting toothed plate, and a mounting plate connected to the stabilizing frame, which is mounted on the bridge pier.

[0008] As a further description of the above technical solution: The lifting assembly includes a fixed plate connected to a connecting plate. A fixed rod is movably connected to the inner side of the connecting plate. A drive gear that meshes with a support gear plate is connected to the fixed rod. A worm gear is connected to the fixed rod, and a worm is meshed on the worm gear.

[0009] As a further description of the above technical solution: The safety drive assembly includes a geared motor, which is fixedly mounted on a connecting plate. The output end of the geared motor is connected to a bevel gear. A transmission gear is connected to the worm gear and meshes with the bevel gear. A support plate is movably connected to the worm gear and is fixedly mounted on the connecting plate. The output end of the geared motor is movably connected to the bottom of the support plate.

[0010] As a further description of the above technical solution: A protective cover is connected to the support plate, and the protective cover is located outside the meshing point of the bevel gear and the transmission gear.

[0011] As a further description of the above technical solution: A speed reducer is connected to the fixed rod. The speed reducer includes a speed belt, which is connected to the fixed rod. The other side of the speed belt is connected to a support toothed plate. A limit wheel is connected to the support toothed plate, and the speed belt is slidably connected to the limit wheel.

[0012] As a further description of the above technical solution: A cross-shaped limiting plate is connected to the support tooth plate, and the cross-shaped limiting plate is slidably connected inside the connecting plate.

[0013] As a further description of the above technical solution: A left sliding frame is slidably connected to the safety platform, and a right sliding frame is slidably connected to the safety platform and inserted into the left sliding frame.

[0014] This utility model has the following beneficial effects: 1. In this utility model, through the setting of the protective component structure, the stabilizing frame connects the support plate and the bridge pier through the mounting plate, so that the emergency escape platform can be set on the side of the bridge body. By setting a set of safety doors on the sound barrier plate, personnel can take emergency escape in the event of a multi-vehicle chain accident or vehicle loss of control on the bridge, avoiding secondary injuries. This realizes the ability to evacuate from the bridge body and avoid the risk of secondary collisions in the event of a car accident or loss of control on a highway bridge sound barrier section.

[0015] 2. In this utility model, with the cooperation of the lifting component and the safety drive component, the safety drive component drives the bevel gear transmission to rotate the transmission gear and worm through the reduction motor. The worm can drive the worm wheel and the drive gear, so that the avoidance platform can move up and down on the support tooth plate. This solves the problem that the avoidance platform can only avoid danger outside the sound barrier plate, but there is still a low risk of parts flying after a collision. The lowered avoidance platform can transfer the personnel to the safe area of ​​the bridge pier to completely avoid the risk of collision. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Reference Figure 1-3 One embodiment of this utility model provides an emergency escape platform for bridge sound barrier sections, including a bridge body 1, a pier 2 connected to the bottom of the bridge body 1, a sound barrier panel 3 installed on the bridge body 1, a safety door 4 installed on the sound barrier panel 3, and further including: The protective component 5 is located on the outside of the sound barrier panel 3 and is used to provide shelter for people in case of danger on the bridge, and to protect the people taking shelter. The protective component 5 includes a safety platform 51, located outside and aligned with the safety gate 4 to allow personnel to pass through and log in. A connecting plate 52 is connected to the safety platform 51, and a support toothed plate 53 is slidably connected to the connecting plate 52. A safety fence 54 is also connected to the safety platform 51. The protective component 5 further includes a stabilizing frame 55, connected to the bottom of the support toothed plate 53. A mounting plate 56 is connected to the stabilizing frame 55 and mounted on the pier 2. A cross-shaped limiting plate 10 is connected to the support toothed plate 53 and slidably connected inside the connecting plate 52, maintaining a continuous connection. The stability of the connecting plate 52 sliding on the supporting toothed plate 53 is ensured by the sliding connection of a left sliding frame 11 and a right sliding frame 12 that is inserted into the left sliding frame 11. By setting the left sliding frame 11 and the right sliding frame 12, personnel can be blocked after entering to prevent them from falling. The left sliding frame 11 and the right sliding frame 12 are connected and fixed by a rectangular metal block on the right sliding frame 12 inserted into a groove on the left sliding frame 11. There is also a circular plug above the right sliding frame 12 to further connect and fix the rectangular metal block inserted between the left sliding frame 11 and the right sliding frame 12, so that the connection stability of the left sliding frame 11 and the right sliding frame 12 is guaranteed during the use of the safety platform. The lifting assembly 6 is mounted on the connecting plate 52 and is used to lift the refuge platform 51 so that the personnel on it can be transferred to a safe area. The safety drive component 7 is mounted on the connecting plate 52 and is used to safely drive the lifting component 6 so that the safety platform 51 can be raised and lowered stably. Specifically, a set of safety doors 4 installed on the sound barrier panel 3 allows two people to enter at the same time, enabling people to quickly enter for emergency evacuation in the event of a multi-vehicle collision or vehicle loss of control on the bridge, thus avoiding secondary injuries. The multi-person safety standing platform composed of the evacuation platform 51 and the evacuation fence 54 allows multiple people to stand and use for evacuation.

[0020] Reference Figure 3-5The lifting assembly 6 includes a fixed plate 61 connected to a connecting plate 52. A fixed rod 62 is movably connected to the inner side of the connecting plate 52. A drive gear 63 that meshes with a support gear plate 53 is connected to the fixed rod 62. A worm gear 64 is connected to the fixed rod 62, and a worm 65 meshes with the worm gear 64. Specifically, the lifting assembly 6 can control the lifting and lowering of the safety platform 51, allowing personnel to selectively avoid danger as needed. A speed reducer 9 is connected to the fixed rod 62, including a speed reduction belt 91 connected to the fixed rod 62. On the fixed rod 62, the other side of the speed bump 91 is connected to the support toothed plate 53. The support toothed plate 53 is connected to the limit wheel 92. The speed bump 91 is slidably connected to the limit wheel 92. The speed bump 91 rotates / winds with the fixed rod 62, so that the speed bump 91 provides tension when the emergency platform 51 is raised and lowered, which assists the raising and lowering of the emergency platform 51. By setting the limit wheel 92, the speed bump 91 can provide a limiting effect during use, prevent the speed bump 91 from deviating, and keep the speed bump 91 wound up.

[0021] Reference Figure 3-5 The safety drive assembly 7 includes a geared motor 71, which is fixedly mounted on a connecting plate 52. A bevel gear 72 is connected to the output end of the geared motor 71. A transmission gear 73 is connected to a worm gear 65, meshing with the bevel gear 72. A support plate 74 is movably connected to the worm gear 65, and the support plate 74 is fixedly mounted on the connecting plate 52. The output end of the geared motor 71 is movably connected to the bottom of the support plate 74. Specifically, the safety drive assembly 7 drives the bevel gear 72 via the geared motor 71, which in turn drives the transmission gear 73 and the worm gear 65 to rotate. The wheel 64 forms a double-locking control for the stable lifting and lowering of the emergency platform 51. The worm gear 65 safely drives the worm wheel 64 and the drive gear 63, enabling the emergency platform 51 to move stably up and down on the support tooth plate 53. The geared motor 71 can be connected to an external power source or a mobile power source can be installed on the connecting plate 52 for its use, depending on the installation environment. A protective cover 8 is connected to the support plate 74. The protective cover 8 is located outside the meshing point of the bevel gear 72 and the transmission gear 73. By setting the protective cover 8, the meshing point of the bevel gear 72 and the transmission gear 73 can be protected to prevent external debris and rainwater from affecting its rotation.

[0022] Working principle: In use, when a multi-vehicle collision or vehicle loss of control occurs on bridge body 1, personnel on bridge body 1 need to pass through safety door 4 to enter the evacuation platform 51. Firstly, safety door 4 can isolate the evacuation personnel from the vehicle accident on bridge body 1, which can further avoid flying debris. Secondly, safety door 4 can allow personnel to quickly evacuate from the accident on bridge body 1. When there is a multi-vehicle collision on bridge body 1, the evacuation personnel need to further avoid risks. The bevel gear 72 driven by the geared motor 71 drives the transmission gear 73 and the worm 65 to rotate, causing the worm 65 to rotate relative to the worm wheel 64, the fixed rod 62, and the drive gear 63. The drive gear 63 engages with the support tooth plate 53 to control the descent of the emergency platform 51. After the emergency platform 51 descends, it is flush with the bridge pier 2. Personnel can enter the platform of the bridge pier 2 to completely avoid the flying debris from vehicle collisions and accidental collisions caused by loss of vehicle control, and wait for rescue. This achieves the goal of allowing personnel to evacuate from the bridge body 1 to a safe area in the event of a car accident or loss of control in the sound barrier section of the highway bridge, thus avoiding the risk of secondary collisions.

[0023] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
