Description

Technical Field

[0001] This utility model relates to the field of road safety technology, and in particular to a protective canopy and protective canopy belt for bridges spanning operating highways. Background Technology

[0002] When constructing and using bridges across operating highways, the operating highways are not closed but are open to traffic. Pedestrians and vehicles traveling on the operating highways are at high risk of being injured by falling debris from the bridge when passing through dangerous sections of the operating highway directly under the bridge. Therefore, it is necessary to build protective sheds in the dangerous sections of the operating highway directly under the bridge to allow pedestrians and vehicles to pass safely under the protection of the sheds. However, the dangerous sections are large, and if only one large protective shed is set up, the shed will be too bulky, making it inconvenient to transport and difficult to build.

[0003] In existing technologies, multiple protective canopies are often spliced ​​together to form a large protective canopy belt, thereby reducing the difficulty of transporting and constructing individual canopies. However, the connection between two adjacent protective canopies is unreliable. When pedestrians and vehicles pass through the protective canopies in dangerous sections of the operating highway directly under bridges, they are prone to hitting the canopy's support pillars, causing adjacent canopies to misalign and creating gaps. Consequently, objects falling from heights can easily fall through these gaps into the dangerous sections of the operating highway directly under bridges, posing a significant safety hazard. Utility Model Content

[0004] The purpose of this utility model is to provide a protective canopy and protective canopy belt for bridges spanning operating highways, which can prevent relative misalignment between adjacent protective canopies when the pillars of the protective canopy are impacted, thereby improving the safety of pedestrians and vehicles traveling on dangerous sections of operating highways located under bridges.

[0005] To achieve this objective, the present invention adopts the following technical solution:

[0006] Firstly, a protective canopy for bridges spanning operational highways is provided, comprising:

[0007] The roof can prevent objects from falling from heights;

[0008] The support column has one end fixedly connected to one side of the roof and the other end fixed to the ground.

[0009] A first connector and a second connector are connected to the roof of the canopy. The first connector is fixedly connected to the roof of the canopy. The first connector can be plugged into and matched with the second connector of the protective canopy for another adjacent cross-operational highway bridge. The shape of the first connector is adapted to the shape of the second connector.

[0010] Preferably, the first connector is slidably connected to the roof, and the first connector can switch between a retracted position inside the roof and a plugged position extending out of the roof; when the first connector is in the plugged position, the first connector can be plugged into and cooperate with the second connector of another adjacent protective canopy for an operating highway bridge.

[0011] Preferably, one of the first connector and the second connector is provided with a snap-fit ​​portion and the other is provided with a snap-fit ​​groove, so that when the first connector is in the plug position, the snap-fit ​​portion and the snap-fit ​​groove engage.

[0012] Preferably, the protective canopy for bridges spanning operating highways also includes auxiliary support columns, one end of which is pivotally connected to the first connector, and the other end of which can be fixed to the ground. The auxiliary support column can switch between a supporting position on the canopy roof and a folded position away from the ground.

[0013] Preferably, the auxiliary support includes a support body and a foot pad. One end of the support body is pivotally connected to the first connector, and the other end is coaxially connected to the foot pad. The foot pad can increase the contact area between the auxiliary support and the ground.

[0014] Preferably, the auxiliary support also includes an elastic element, and the foot pad is elastically connected to the support body through the elastic element.

[0015] Preferably, the protective canopy for bridges spanning operating highways also includes a baffle plate fixed to the support column. When the first connector is in the retracted position, the baffle plate can limit the maximum rotation angle of the auxiliary support column.

[0016] Preferably, the protective canopy for bridges spanning operating highways also includes a display panel, and at least two pillars are arranged parallel to each other and spaced apart; one end of the display panel is fixedly connected to one of the pillars, and the other end is fixedly connected to the other pillar.

[0017] Preferably, the canopy roof has a rounded top, which is located on the side of the canopy roof away from the support pillar.

[0018] Secondly, a protective canopy for cross-operational highway bridges is provided, wherein at least two of the above-mentioned protective canopies for cross-operational highway bridges are arranged sequentially and continuously, and a first connector is inserted and engaged with a second connector of another adjacent protective canopy for cross-operational highway bridges.

[0019] The beneficial effects of this utility model are:

[0020] The protective canopy for bridges spanning operational highways provided by this utility model uses the canopy roof to block falling objects from the bridge, protecting pedestrians and vehicles traveling on the dangerous section of the operational highway directly beneath the bridge. One end of a support pillar is fixed to one side of the canopy roof, while the other end is fixed to the ground, thus supporting the roof and providing space for pedestrians and vehicles to pass. A first connector is provided that engages with a second connector of an adjacent protective canopy. The shapes of the first and second connectors are adapted to each other, ensuring that no displacement occurs between the first and second connectors when pedestrians or vehicles collide with the support pillar. This prevents misalignment between adjacent protective canopies, thus preventing falling objects from entering the dangerous area of ​​the operational highway directly beneath the bridge through the gap created by such misalignment. This greatly improves the safety of the protective canopy, protecting pedestrians and vehicles traveling on the dangerous section of the operational highway directly beneath the bridge from injury by falling objects.

Detailed Implementation

[0027] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0028] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0029] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0030] In the description of this embodiment, the terms "upper," "lower," "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0031] In existing technologies, the connection between two adjacent protective canopies is unreliable. When pedestrians and vehicles pass through the protective canopies in dangerous sections of operating highways located under bridges, they are prone to colliding with the canopy's supports, causing adjacent canopies to misalign and creating gaps between them. Therefore, even with protective canopies installed, safety hazards remain in dangerous sections of operating highways located under bridges. The key to solving this technical problem is ensuring that adjacent protective canopies do not misalign upon impact. The following section will discuss this further. Figures 1 to 4 This utility model provides a detailed description of the protective canopy for cross-operational highway bridges.

[0032] Figure 1 This embodiment shows a structural schematic diagram of the protective canopy for bridges spanning operational highways provided in this embodiment. Figure 2 It shows Figure 1 A cross-sectional diagram in one direction. (See example) Figures 1 to 2As shown, the protective canopy for bridges spanning operational highways provided in this embodiment includes a canopy roof 1, a support column 2, a first connector 3, and a second connector 4. The canopy roof 1 can block falling objects from heights; one end of the support column 2 is fixedly connected to one side of the canopy roof 1, and the other end is fixed to the ground; the first connector 3 is connected to the canopy roof 1, and the second connector 4 is fixedly connected to the canopy roof 1. The first connector 3 can be plugged into and cooperate with the second connector 4 of another adjacent protective canopy, and the shape of the first connector 3 is adapted to the shape of the second connector 4. Specifically, the second connector 4 can be a trapezoidal groove, a T-shaped groove, or a linear rail, and the first connector 3 is a slider. The slider is adapted to the trapezoidal groove, T-shaped groove, or linear rail, so that when the support column 2 is hit by a pedestrian or vehicle, the two adjacent protective canopies will not be misaligned.

[0033] The protective canopy for bridges spanning operational highways provided in this embodiment uses the canopy roof 1 to block falling objects from the bridge, protecting pedestrians and vehicles traveling on the dangerous section of the operational highway directly beneath the bridge. One end of a support pillar 2 is fixed to one side of the canopy roof 1, while the other end is fixed to the ground, thus supporting the canopy roof 1 and providing space for pedestrians and vehicles to pass. A first connector 3 is provided to engage with a second connector 4 of an adjacent protective canopy. The shapes of the first connector 3 and the second connector 4 are compatible, ensuring that when pedestrians or vehicles collide with the support pillar 2, there is no displacement between the first connector 3 and the second connector 4. This prevents misalignment between adjacent protective canopies, thus preventing falling objects from entering the dangerous area of ​​the operational highway directly beneath the bridge through the gap created by such misalignment. This greatly improves the safety of the protective canopy, protecting pedestrians and vehicles traveling on the dangerous section of the operational highway directly beneath the bridge from injury by falling objects.

[0034] Continue as Figures 1 to 2 As shown, the first connector 3 is slidably connected to the roof 1, and the first connector 3 can switch between a retracted position inside the roof 1 and a plugged position extending out of the roof 1. When the first connector 3 is in the plugged position, it can engage with the second connector 4 of another adjacent protective shed. Therefore, when transporting the protective shed for the bridge spanning an operational highway, the first connector 3 can be retracted inside the roof 1, reducing the volume of a single protective shed and thus reducing the difficulty of transporting it. When assembling the protective shed, the first connector 3 can be switched to the plugged position to engage with the second connector 4 of another adjacent protective shed, thereby reducing the assembly difficulty of the protective shed for the bridge spanning an operational highway. Specifically, the roof 1 has a sliding groove, within which the first connector 3 can slide, thus achieving a sliding connection relative to the roof 1.

[0035] Figure 3 It shows Figure 1In a cross-sectional view from another direction, after the first connector 3 and the second connector 4 are inserted and engaged, and two adjacent protective canopies are spliced ​​together, after prolonged use, vibration or other reasons inevitably cause the first connector 3 and the second connector 4 to move relative to each other and no longer engage. This results in the loosening of the splicing of the two adjacent protective canopies. Consequently, when the support column 2 of the protective canopy across the operating highway bridge is impacted, the two adjacent protective canopies misalign, creating a gap between them. To solve the above technical problem, such as... Figures 1 to 3 As shown, the first connector 3 is provided with a snap-fit ​​part 31, and the second connector is provided with a snap-fit ​​groove 41. When the first connector 3 is in the insertion position, the snap-fit ​​part 31 engages with the snap-fit ​​groove 41, thereby preventing relative displacement between the first connector 3 and the second connector 4 and thus preventing them from engaging. Specifically, the snap-fit ​​part 31 is a snap-fit ​​block, and the snap-fit ​​groove 41 is a groove that matches the shape of the snap-fit ​​block. The snap-fit ​​block and the groove engage with each other, thereby preventing relative movement between the first connector 3 and the second connector 4. It is worth noting that in this embodiment, the snap-fit ​​part 31 only engages with the snap-fit ​​groove 41 when the first connector 3 is in the insertion position. When it is necessary to disassemble the protective canopy, the worker can separate the snap-fit ​​part 31 from the snap-fit ​​groove 41, and normally allow the first connector 3 and the second connector 4 to move relative to each other and no longer engage, thereby enabling the normal disassembly of the protective canopy.

[0036] In other embodiments, the first connector 3 is provided with a snap-fit ​​groove 41, and the second connector 4 is provided with a snap-fit ​​part 31. When the first connector 3 is in the plugged position, the snap-fit ​​part 31 engages with the snap-fit ​​groove 41, thereby preventing the first connector 3 and the second connector 4 from moving relative to each other and no longer engaging.

[0037] like Figures 1 to 2 As shown, the protective canopy for bridges spanning operational highways also includes auxiliary support pillars 5. One end of the auxiliary support pillar 5 is pivotally connected to the first connector 3, and the other end can be fixed to the ground, thereby supporting the canopy roof 1 and increasing the number of supporting components for the roof 1. This better supports the roof 1, improves the stability of the protective canopy, and prevents it from collapsing during use. It is worth noting that the number of auxiliary support pillars 5 in this embodiment is not limited and can be one, two, three, or even more, as long as they can stably support the roof 1. Further details will not be elaborated here.

[0038] Preferably, the auxiliary support column 5 can switch between its supporting position on the roof 1 and its folded position away from the ground, so that the auxiliary support column 5 can be in the folded position during the transportation of the protective shed, thereby reducing the space volume of the protective shed and reducing the difficulty of transporting the protective shed.

[0039] Continue as Figures 1 to 2As shown, the auxiliary support 5 includes an auxiliary support body 51 and a foot pad 52. One end of the auxiliary support body 51 is pivotally connected to the first connector 3, and the other end is coaxially connected to the foot pad 52. The foot pad 52 can increase the contact area between the auxiliary support 5 and the ground, so that the auxiliary support 5 can more stably support the roof 1, thereby improving the stability of the protective shed.

[0040] Optionally, the auxiliary support body 51 includes a first auxiliary support body 511 and a second auxiliary support body 512. One end of the first auxiliary support body 511 is pivotally connected to the first connector 3, and the other end is pivotally connected to the second auxiliary support body 512. The second auxiliary support body 512 can contact the ground so that the auxiliary support body 51 supports the first connector 3 and indirectly supports the canopy 1.

[0041] Continue as Figures 1 to 2 As shown, the auxiliary support column 5 also includes an elastic element 53. The foot pad 52 is elastically connected to the auxiliary support column body 51 through the elastic element 53. When the auxiliary support column 5 is in the supported position, the elastic force provided by the compression elastic element 53 is used to increase the friction between the foot pad 52 and the ground, thereby enabling the auxiliary support column 5 to more stably support the canopy 1, thus improving the stability of the protective canopy. Specifically, the elastic element 53 is a spring. The auxiliary support column body 51 has a receiving groove for accommodating the elastic element 53 at one end adjacent to the ground. The spring is accommodated in the receiving groove, with one end of the spring fixedly connected to the auxiliary support column body 51 and the other end fixedly connected to the foot pad 52.

[0042] Continue as Figures 1 to 2 As shown, the protective canopy for bridges spanning operating highways also includes a display board 7. At least two pillars 2 are set parallel to each other and spaced apart. One end of the display board 7 is fixedly connected to one of the pillars 2, and the other end is fixedly connected to the other pillar 2, so that warning information can be posted on the display board 7 to remind pedestrians and vehicles traveling on the dangerous section of the operating highway directly under the bridge that the current section is a dangerous section and they should slow down and pass safely.

[0043] Continue as Figures 1 to 2 As shown, the roof 1 has an arc-shaped top 11, which is located on the side of the roof 1 away from the support column 2. This allows rainwater to drain from the roof 1 through the arc-shaped top 11 in a timely manner, preventing rainwater from accumulating on the roof 1 and collapsing the protective shed.

[0044] Figure 4 This diagram illustrates the structure of the protective canopy for bridges spanning operational highways provided by this invention from another direction. (See diagram below.) Figure 4 Combination Figures 1 to 2As shown, the protective canopy for bridges spanning operational highways also includes a baffle 6, which is fixed to the support column 2. When the first connector 3 is in the retracted position, the baffle 6 can limit the maximum rotation angle of the auxiliary support column 5. This prevents the auxiliary support column 5 from rotating and falling and injuring workers before the first connector 3 is in the insertion position during the assembly of the protective canopy, thus protecting the personal safety of the workers assembling the protective canopy. Specifically, the baffle 6 can spatially interfere with the foot pad 52 when the auxiliary support column 5 rotates, thereby limiting the maximum rotation angle of the auxiliary support column 5.

[0045] This embodiment also provides a protective canopy belt, such as Figures 1 to 4 As shown, at least two protective canopies for cross-operating highway bridges are installed sequentially. The first connector 3 of one protective canopy for cross-operating highway bridge is connected to the second connector 4 of another adjacent protective canopy for cross-operating highway bridge. The shape of the first connector 3 is adapted to the shape of the second connector 4, so that multiple protective canopies can be spliced ​​into a large protective canopy strip to increase the protective area of ​​the protective canopy, reduce the assembly difficulty of the protective canopy, and when the protective canopy is hit by a collision, there will be no relative misalignment between adjacent protective canopies, thereby improving the safety of pedestrians and vehicles passing through dangerous sections of the operating highway that are located under the bridge.

[0046] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
