Description

Technical Field

[0001] This utility model belongs to the technical field of highway safety protection equipment, specifically relating to a filler guardrail. Background Technology

[0002] Highway guardrails are safety facilities installed on the edge of roads or in the median strip. Their main purpose is to prevent vehicles from running off the road after losing control and to reduce collision damage in the event of a traffic accident. Most existing guardrails are made of inelastic iron, which cannot absorb kinetic energy when colliding with a car and cannot buffer the impact force. The dynamic shear force experienced by the colliding vehicle is significant, easily causing serious damage and even injury or death to the occupants.

[0003] Chinese patent document CN221345396U (202323178773.2) discloses a guardrail structure. This utility model's protective barrier includes an iron shell and a filler material within the iron shell. During use, it is not anchored to the ground and is unaffected by the foundation. When a vehicle collides, the weight of the guardrail components increases ground friction, preventing further impact. Simultaneously, the guardrail components can also shift to cushion the vehicle and guide the absorption of collision energy. After the collision, the displaced guardrail structure can be quickly repositioned manually or using a lifting device, resulting in low maintenance costs. However, the aforementioned protective barrier requires pre-filled concrete within the shell, increasing manufacturing and transportation costs. Utility Model Content

[0004] The purpose of this invention is to design a filler guardrail. By setting a filler shell, it is used to fill the guardrail with counterweights such as sand or soil on site, thereby reducing transportation and manufacturing costs. By setting a protective frame on the outside of the filler shell, the impact resistance of the protective unit is further improved. By using connecting components to connect two adjacent protective frames together, rapid assembly is achieved.

[0005] The technical problem to be solved by this utility model is achieved by the following technical solution: a filler guardrail, including a protective unit and a connecting component;

[0006] The plurality of the protective units are arranged in a linear manner, and the protective unit includes a filling shell and a protective frame disposed outside the filling shell;

[0007] The protective frame is provided with mounting positions that match the filling shell;

[0008] The connecting component is used to connect two adjacent protective frames together.

[0009] In a preferred embodiment of this invention, the protective frame comprises a rectangular frame arranged at intervals on the left and right sides and transverse anti-collision bars located on the front and rear sides of the rectangular frame.

[0010] The two ends of the transverse anti-collision bar are detachably mounted on the rectangular frame by bolts;

[0011] The filling shell is provided with a limiting groove that matches the lateral anti-collision bar;

[0012] The connecting assembly includes a connecting strip, the two ends of which are respectively connected to the transverse anti-collision bars of two adjacent protective frames. The transverse anti-collision bars are connected to the rectangular frame to form the main body of the protective frame. Limiting grooves matching the transverse anti-collision bars are provided on the filling shell, thereby connecting the filling shell and the protective frame together, facilitating the overall transportation of the protective unit.

[0013] Preferably, in this invention, the protective frame further includes a movable rod located above the filling shell, with both ends of the movable rod detachably mounted on the rectangular frame. Because the movable rod is positioned above the filling shell, force can be applied to the protective unit via the movable rod, thereby facilitating the movement of the protective unit's position.

[0014] In a preferred embodiment of this invention, the protective frame further includes a vertical protective rod disposed between the movable rod and the rectangular frame;

[0015] The vertical guardrails are connected to the movable pole and the rectangular frame, respectively. The vertical guardrails allow the movable pole to be erected, increasing the overall protective height of the infill fence.

[0016] In a preferred embodiment of this utility model, the protective frame further includes a limiting rod arranged parallel to the rectangular frame, with both ends of the limiting rod respectively disposed on the transverse anti-collision rod;

[0017] There are two or more installation positions, and the two or more infill shells are respectively arranged between the rectangular frame and the limiting rod or between two limiting rods. When there are two or more installation positions, by setting a limiting rod between two adjacent infill shells, the infill shell can be arranged between the rectangular frame and the limiting rod or between two limiting rods, thereby supporting and protecting the infill shell and enhancing the overall strength of the infill guardrail.

[0018] The limiting rod is slidably fitted onto the transverse anti-collision bar at both ends. By slidably fitting the limiting rod onto the transverse anti-collision bar at both ends, the position of the limiting rod can be easily adjusted according to the size of the filling shell.

[0019] In a preferred embodiment of this invention, the filling shell comprises a base plate and side plates formed by stamping sheet metal, and the base plate and side plates are connected by bolts. The base plate and side plates are formed by stamping and bending sheet metal, and then bolts are used to connect the base plate and side plates to form the filling shell. The overall structure is simple and easy to assemble.

[0020] Preferably, in this invention, there are two or more mounting positions, with adjacent infill shells spaced apart within their respective mounting positions. To reduce costs, the sheet metal is typically thin, thus limiting the size of the base plate and side plates. To improve the impact resistance of the protective unit, each protective unit has two or more infill shells made of sheet metal. Given the limited space of a single infill shell, increasing the number of infill shells increases the overall weight of the protective unit, thereby improving its impact resistance.

[0021] In a preferred embodiment of this invention, the filling shell comprises a base plate and side plates made of corrugated plates, which are connected by bolts. The corrugated plates have a relatively large thickness and overall strength. Using discarded corrugated plates directly to manufacture the base plate and side plates saves on the processing cost of the filling shell and enables the recycling of waste corrugated plates.

[0022] In this invention, there is only one mounting position, and the length of the side plate of the filling shell along the arrangement direction of the protective units is greater than the length of the side plate perpendicular to the arrangement direction of the protective units. Because the corrugated plate has high overall strength, each protective unit is provided with only one filling shell. The length of the side plate of the filling shell along the arrangement direction of the protective units is greater than the length of the side plate perpendicular to the arrangement direction of the protective units, ensuring the impact resistance of the protective units while avoiding excessive weight that would make movement difficult.

[0023] In a preferred embodiment of this utility model, the filling shell includes a flexible square bag body, a folding support plate, and a connecting support plate;

[0024] Two foldable support plates are foldably connected and disposed on the front and rear side walls of the flexible square bag body, and the connecting support plates are disposed on the left and right side walls of the flexible square bag body.

[0025] The folding support plate and the connecting support plate are foldably connected together. By foldably connecting two folding support plates on the front and rear side walls of the flexible square bag, and setting the connecting support plate on the left and right side walls of the flexible square bag, and foldably connecting the folding support plates and the connecting support plates together, the filling shell can be folded together along the folding axis of the two folding support plates. During construction, it can be opened to fill the flexible square bag, which saves storage and transportation space for the filling shell. In addition, the use of folding support plates and connecting support plates can also further increase the overall impact resistance of the infill guardrail.

[0026] In a preferred embodiment of this invention, the filling shell comprises multiple flexible square bags arranged side by side, with adjacent flexible square bags sharing a connecting support plate. By arranging multiple flexible square bags side by side, a single filling shell can be divided into multiple filling units, resulting in better impact resistance.

[0027] Preferably, the sidewall of the filling shell is an airbag structure. The sidewall of the filling shell is designed as an airbag structure using a flexible material, and gas is injected into the sidewall of the filling shell on-site to form a filling cavity.

[0028] Compared with existing technologies, the advantages of this utility model are as follows: The infill guardrail of this utility model includes protective units and connecting components. Multiple protective units are arranged linearly. Each protective unit includes a filling shell and a protective frame disposed on the outside of the filling shell. The protective frame is provided with mounting positions that match the filling shell for fixing the filling shell. The impact resistance performance can be met by filling the filling shell with counterweights such as sand or soil on site. Furthermore, since the protective frame is disposed on the outside of the filling shell, its structure further improves the strength and impact resistance of the protective unit. Adjacent protective frames are connected together using the connecting components to form an integrated guardrail structure, which is convenient to install. Attached Figure Description

[0040] The technical solutions in the embodiments of this utility model will now be clearly and completely described in conjunction with the accompanying drawings.

[0041] Example 1

[0042] like Figure 1 and Figure 2 As shown, a type of infill guardrail includes a protective unit 1 and a connecting component 2.

[0043] Multiple protective units 1 are arranged linearly, each protective unit 1 including a filling housing 11 and a protective frame 12 disposed outside the filling housing 11. In this embodiment, the opening of the filling housing 11 is oriented upwards.

[0044] The protective frame 12 is provided with a mounting position 100 that matches the filling shell 11.

[0046] The protective frame 12 includes rectangular frames 121 spaced apart on the left and right sides and transverse anti-collision bars 122 located on the front and rear sides of the rectangular frames 121. In this embodiment, a reinforcing bar is also provided in the middle of the rectangular frames 121 to improve the overall strength of the protective frame 12.

[0047] The transverse anti-collision bar 122 is detachably mounted on the rectangular frame 121 at both ends by bolts.

[0048] The filling shell 11 is provided with a limiting groove 111 that matches the lateral anti-collision bar 122, and the lateral anti-collision bar 122 is engaged in the limiting groove 111. In this embodiment, the filling shell 11 has two parallel limiting grooves 111 on its front and rear sides respectively.

[0049] The connecting component 2 includes a connecting strip 21, the two ends of which are connected to the transverse anti-collision bars 122 of two adjacent protective frames 12 by bolts.

[0050] The protective frame 12 also includes a movable rod 123 located above the filling shell 11. The movable rod 123 is detachably mounted at both ends above the rectangular frame 121. The movable rod 123 forms a basket-like structure by connecting with the rectangular frame 121. Since the filling shell 11 is fixedly connected to the protective frame 12 via the transverse anti-collision bar 122, the movable rod 123 can apply force to the filling shell 11, thereby lifting the filling shell 11 and moving it to a corresponding position.

[0051] The protective frame 12 also includes a limiting rod 124 arranged parallel to the rectangular frame 121, with both ends of the limiting rod 124 respectively arranged on the transverse anti-collision rod 122.

[0052] In this embodiment, there are two mounting positions 100, and the two filling shells 11 are respectively disposed between the rectangular frame 121 and the limiting rod 124.

[0053] The limiting rod 124 is slidably mounted on the transverse anti-collision rod 122 at both ends.

[0054] The protective frame 12 also includes a vertical protective rod 125 disposed between the movable rod 123 and the rectangular frame 121.

[0055] The vertical protective rod 125 is connected to the movable rod 123 and the rectangular frame 121 respectively. In this embodiment, the vertical protective rod 125 is a pad tube with a rectangular cross-section, and the movable rod 123 and the vertical protective rod 125 are fixed together to the upper end of the rectangular frame 121 by bolts.

[0060] There is one mounting position 100, and the length of the side plate of the filling shell 11 along the arrangement direction of the protective unit 1 is greater than the length of the side plate perpendicular to the arrangement direction of the protective unit 1.

[0061] In this embodiment, the vertical guard rod 125 is a bent piece made of sheet metal. The lower end of the vertical guard rod 125 is welded to the upper end of the rectangular frame 121. The movable rod 123 is connected to the vertical guard rod 125 by bolts.

[0062] Example 3

[0063] like Figure 4 and Figure 5 As shown, the difference from Embodiment 1 is that the filling shell 11 includes a flexible square bag body 3, a folding support plate 4, and a connecting support plate 5.

[0064] Two folding support plates 4 are foldably connected together via a hinge shaft and are disposed on the front and rear side walls of the flexible square bag body 3. The connecting support plate 5 is disposed on the left and right side walls of the flexible square bag body 3. Alternatively, the two folding support plates 4 can be directly fixed to the side walls of the flexible square bag body 3 without connecting them.

[0065] In this embodiment, the flexible square bag 3 is made of high-strength polymer material to ensure service life and further improve the impact resistance of the guardrail.

[0066] In this embodiment, the folding support plate 4 and the connecting support plate 5 are made of wire mesh.

[0067] The folding support plate 4 and the connecting support plate 5 are foldably connected together via a hinge shaft. Alternatively, the folding support plate 4 and the connecting support plate 5 can be directly fixed to the side wall of the flexible square bag body 3 without connecting them.

[0068] The filling shell 11 includes a plurality of flexible square bags 3 arranged in parallel, with two adjacent flexible square bags 3 sharing a connecting support plate 5.

[0069] Example 4

[0070] like Figure 6 As shown, the difference from Embodiment 1 is that the sidewall of the filling shell 11 is an airbag structure. Specifically, the filling shell 11 is a high-strength polymer material airbag.
