Technical Field

[0001] The utility model relates to the technical field of traffic facilities, in particular to an isolation guardrail for road traffic. Background Art

[0002] Traffic guardrail is a safety facility used in traffic places such as roads, highways, bridges, tunnels, etc., designed to protect the safety of vehicles and pedestrians. Its main function is protection and guidance.

[0003] In the prior art, the Chinese invention patent application document with publication number CN117822491A discloses an aluminum alloy traffic guardrail that is easy to install. The aluminum alloy traffic guardrail is provided with a connecting mechanism. The plug-in block on the right side of the traffic guardrail is inserted into the plug-in slot. Under the action of the spring, the limit block is engaged with the card slot, which facilitates installation. At the same time, the rotating plate can rotate relative to the connecting block under the action of the main shaft, which facilitates the adjustment of the angle between the traffic guardrails.

[0004] In the above-mentioned aluminum alloy traffic guardrail, although the relative angles between the traffic guardrails can be adjusted, a complex connection structure needs to be set on the inner side of both ends of the traffic guardrail, and the cross-sectional size of the inner side of the guardrail is limited. Therefore, setting a complex connection structure in a limited space leads to high production costs; not only that, the traffic guardrail adopts an integral structure, resulting in a large space occupied during transportation and storage, which increases the transportation and storage costs; in addition, this type of traffic guardrail is heavy, which further increases the transportation cost and the difficulty of construction and installation.

[0005] Therefore, it is necessary to improve the traffic guardrail in the prior art. Utility Model Content

[0006] Therefore, the technical problem to be solved by the present invention is to overcome the technical problems of the prior art such as complex structure, high production, storage and transportation costs, and high installation difficulty.

[0008] A column assembly, the column assembly comprising at least three support columns spaced apart and extending in a vertical direction;

[0009] A guardrail assembly is provided between two adjacent column assemblies, and includes at least two crossbeams arranged side by side, and vertical poles arranged side by side along the length direction of the crossbeams and detachably provided between the adjacent crossbeams;

[0010] A connecting assembly is provided between the end of the beam and the support column in a one-to-one correspondence. The connecting assembly and the beam have a rotating rod and a rotating sleeve that are rotatably connected with each other and the rotation axis extends in the vertical direction. One of the rotating rod and the rotating sleeve is provided on the beam, and the other is detachably provided on the support column.

[0011] As a further improvement of the present invention, in order to realize the relative rotation connection between the support column and the crossbeam, a groove-shaped mounting seat is provided on the side wall of the support column, the mounting seat is facing away from the support column and the two side walls are distributed along the vertical direction, the rotating sleeve is provided at the end of the crossbeam and is located on the inner side of the mounting seat, and the rotating rod is detachably provided on the mounting seat.

[0012] As a further improvement of the present invention, in order to achieve a detachable connection between the rotating shaft and the support column, the connecting assembly also includes a convex cap and a screw rod coaxially connected to the two ends of the rotating rod, the rod body formed by the screw rod and the rotating rod passes through the mounting seat, and the screw rod is threadedly connected with a threaded sleeve.

[0013] As a further improvement of the present invention, in order to facilitate locking the rotation angle position of the crossbeam, a first through hole and a second through hole are respectively provided on the two side walls of the mounting seat, the inner diameter of the first through hole is consistent with the outer diameter of the rotating rod and is smaller than the outer diameter of the convex cap, and the circumferential outer edge of the adjacent end of the screw sleeve and the convex cap is integrally provided with an annular flange, and the inner diameter of the second through hole is consistent with the outer diameter of the flange.

[0014] As a further improvement of the present invention, in order to achieve a detachable connection between the crossbeam and the vertical pole, a surface of the crossbeam adjacent to the vertical pole is provided with a socket that is plugged into and fits with the vertical pole.

[0016] As a further improvement of the present invention, in order to ensure a sealed connection between the vertical pole and the horizontal beam, the vertical pole includes a vertical pole and a sealing cover which is an elastic sealing sleeve provided at both ends of the vertical pole. The end of the vertical pole is sealedly connected to one of the inner side walls of the horizontal tube and the circumferential inner wall of the socket through the sealing sleeve.

[0017] As a further improvement of the present invention, in order to reduce the weight of the vertical rod, lower the production cost and facilitate transportation, the vertical rod is a hollow vertical tube.

[0018] As a further improvement of the present invention, in order to enhance the structural strength of the vertical rod, the inner cavity of the vertical rod is filled with an elastomer.

The terms used herein in the specification of this invention are intended solely for the purpose of describing specific embodiments and are not intended to constrain this invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0034] The terms "first", "second", "third" and the like in the present invention do not represent specific quantities and orders, but are only used to distinguish names.

[0035] Reference Figures 1-8 As shown, the utility model is a road traffic isolation guardrail, comprising:

[0036] The column assembly 1 includes at least three support columns 11 that are spaced apart and extend in a vertical direction.

[0037] A guardrail assembly is provided between two adjacent column assemblies 1. The guardrail assembly includes at least two beams 2 arranged side by side, and upright poles 3 arranged side by side along the length direction of the beams 2 and detachably provided between adjacent beams 2.

[0038] The connecting assembly 4 is arranged one-to-one between the end of the beam 2 and the support column 11. The connecting assembly 4 and the beam 2 have a rotating rod 41 and a rotating sleeve 21 that are rotatably connected and the rotation axis extends along the vertical direction. One of the rotating rod 41 and the rotating sleeve 21 is arranged on the beam 2, and the other is detachably arranged on the support column 11.

[0039] Specifically, four column assemblies 1 are provided, and correspondingly, three guardrail assemblies are provided. The three guardrail assemblies and the four column assemblies 1 are spaced apart in sequence to form a "Z"-shaped structure. Of course, in actual application, the number of column assemblies 1 and guardrail assemblies can also be other. It is only necessary to ensure that the two adjacent column assemblies 1 are connected by the guardrail assembly, that is, the number of guardrail assemblies is one less than the number of column assemblies 1. The distribution method of the two can be adjusted accordingly according to the extension conditions of the road surface.

[0040] In the guardrail assembly, two crossbeams 2 are provided, which are arranged side by side in the vertical direction to reduce the number of crossbeams 2. A plurality of vertical poles 3 are arranged between the two crossbeams 2 and are arranged side by side along the length direction of the two crossbeams 2. The ends of the vertical poles 3 are detachably connected to the two crossbeams 2. After adopting the above structure, the vertical poles 3 and the crossbeams 2 adopt a split splicing structure, that is, during storage and transportation, the vertical poles 3 can be separated from the crossbeams 2, thereby reducing the occupied space and lowering the storage and transportation costs. On site, the vertical poles 3 can be quickly connected to the crossbeams 2 to form a guardrail assembly, and then connected to the support column 11 in the column assembly 1 through the connecting component 4, thereby forming a guardrail assembly as shown in FIG. Figure 1 The isolation guardrail.

[0041] Unlike the prior art, the connecting component 4 is arranged between the end of the beam 2 and the support column 11. Specifically, the connecting component 4 is located on the outside of the support column 11, and the connecting component 4 and the beam 2 have a rotating rod 41 and a rotating sleeve 21 that are rotatably connected. Therefore, compared to setting up a complex mechanism in the limited inner space of the support column 11, the traffic guardrail of the present invention has a simple structure of the connecting component 4 on the basis of satisfying that the guardrail component can adjust the angle with the column component 1 according to the road conditions, thereby reducing production costs.

[0042] A further improvement is that a groove-shaped mounting seat 12 is provided on the side wall of the support column 11, the mounting seat 12 is facing away from the support column 11 and the two side walls are distributed along the vertical direction, the rotating sleeve 21 is provided at the end of the beam 2 and is located on the inner side of the mounting seat 12, and the rotating rod 41 is detachably provided on the mounting seat 12.

[0043] Specifically, two mounting seats 12 distributed along the height direction of the support column 11 are welded and fixed on the two outer side walls opposite to each other. The mounting seat 12 is a U-shaped groove structure, with its groove facing away from the support column 11, and the two side walls are distributed along the vertical direction and arranged horizontally. The rotating sleeve 21 is welded and fixed to the two end positions of the beam 2, and the rotating rod 41 is detachably arranged on the mounting seat 12.

[0044] After adopting the above structure, when connecting the column assembly 1 with the guardrail assembly, the rotating sleeve 21 is placed on the inner side of the mounting seat 12, and the rotating rod 41 is installed on the mounting seat 12, so that the rotating sleeve 21 can rotate around the axis of the rotating rod 41, thereby adjusting the angular position of the guardrail assembly.

[0045] To be more specific, the connecting assembly 4 also includes a convex cap 42 and a screw 43 coaxially connected to the two ends of the rotating rod 41. The rod body formed by the combination of the screw 43 and the rotating rod 41 passes through the mounting seat 12, and the screw 43 is threadedly connected to the screw sleeve 44; a first through hole 121 and a second through hole 122 are respectively provided on the two side walls of the mounting seat 12, the inner diameter of the first through hole 121 is consistent with the outer diameter of the rotating rod 41 and is smaller than the outer diameter of the convex cap 42, and the circumferential outer edge of the screw sleeve 44 adjacent to the convex cap 42 is integrally provided with an annular flange 441, and the inner diameter of the second through hole 122 is consistent with the outer diameter of the flange 441.

[0046] like Figure 7 and Figure 8 As shown, the connecting assembly 4 includes a rotating rod 41, a convex cap 42, a screw 43, a screw sleeve 44 and a washer 45, wherein the convex cap 42, the rotating rod 41 and the screw 43 are connected integrally along the coaxial centerline to form a bolt structure, and the circumferential outer edge of the screw sleeve 44 adjacent to the convex cap 42 is provided with a flange 441. Correspondingly, a first through hole 121 and a second through hole 122 coaxially are provided on the two side walls of the mounting seat 12. The inner diameter of the first through hole 121 and the inner diameter of the rotating sleeve 21 are consistent with the outer diameter of the rotating rod 41, and the inner diameter of the second through hole 122 is consistent with the outer diameter of the washer 45. During on-site assembly, after the vertical pole 3 and the crossbeam 2 are spliced to form a guardrail assembly, the rotating sleeve 21 at the end of the crossbeam 2 is inserted into the inner side of the mounting seat 12 , so that the axis line of the rotating sleeve 21 is aligned with the axis line of the first through hole 121, the rotating rod 41 is inserted into the inner side of the first through hole 121 and the rotating sleeve 21, so that the convex cap 42 rests on one of the outer side walls of the mounting seat 12, and then the washer 45 is inserted into the outer side of the screw rod 43, and then the screw sleeve 44 is screwed in, so that the washer 45 enters the inner side of the second through hole 122 and fits on the flange 441 and the rotating sleeve 21, and then the crossbeam 2 can be rotated to adjust the angular position of the guardrail assembly. After the adjustment is completed, the screw sleeve 44 is tightened so that the rotating sleeve 21 is clamped and fixed on the washer 45 and one of the inner side walls of the mounting seat 12, thereby fixing the position of the rotating sleeve 21 and the crossbeam 2, and then the angular position of the guardrail assembly can be fixed.

[0047] A further improvement is that a socket 221 which is plugged into the upright pole 3 is provided on one side of the crossbeam 2 adjacent to the upright pole 3 . The crossbeam 2 includes a cross tube 22 , and the socket 221 is a through hole provided on the side wall of the cross tube 22 .

[0048] Specifically, such as Figure 5 and Figure 6 As shown, both crossbeams 2 include a cross tube 22 and a rotating sleeve 21 welded to both ends of the cross tube 22. The above design results in a hollow crossbeam 2. This reduces the amount of material used in the production of the crossbeam 2, lowering production costs. Furthermore, it reduces the weight of the crossbeam 2, facilitating transportation, installation, and handling. The cross-sections of the circumferential outer edges and circumferential inner walls of the two cross tubes 22 are concentric squares. One of the side walls of the cross tube 22 is provided with insertion holes 221 spaced evenly along its length. These insertion holes 221 are through holes, facilitating the insertion of the ends of the uprights 3. After splicing, the end faces of the uprights 3 can abut against the inner sidewall of the cross tube 22 opposite the sidewall where the insertion holes 221 are located, ensuring the stability of the guardrail assembly structure.

[0049] A further improvement is that the vertical rod 3 includes a vertical rod 31 and a sealing cover which is an elastic sealing sleeve 32 provided at both ends of the vertical rod 31. The end of the vertical rod 31 is sealedly connected to one of the inner side walls of the horizontal tube 22 and the circumferential inner wall of the socket 221 through the sealing sleeve 32; the vertical rod 31 is a hollow vertical tube; the inner cavity of the vertical rod 31 is filled with an elastomer 33.

[0050] The vertical rod 3 primarily consists of a hollow vertical rod 31, an elastic member 33 filling the interior of the vertical rod 31, and rubber sealing sleeves 32 at each end of the vertical rod 31. The hollow structure of the vertical rod 31, similar to the horizontal tube 22, also reduces the material consumption of the traffic barrier, thereby lowering production costs, reducing weight, and facilitating transportation and installation.

[0051] A sealing sleeve 32 made of rubber is provided at the end of the vertical rod 31, so that when the vertical rod 3 is spliced with the cross beam 2, the sealing sleeve 32 can abut against the inner wall of the cross tube 22 with the side facing away from the vertical rod 31 through its own elastic deformation, and the circumferential outer edge and circumferential inner wall of the sealing sleeve 32 are sealed with the circumferential inner wall of the insertion hole 221 and the circumferential outer edge of the vertical rod 31 respectively, thereby ensuring the sealed connection between the vertical rod 3 and the cross beam 2 and reducing the requirements for the cross-sectional dimensions of the insertion hole 221 and the vertical rod 31.

[0052] The elastomer 33 is pre-installed into the inner side of the vertical rod 31 before the sealing sleeve 32 is covered on the end of the vertical rod 31. There are many options for the elastomer 33, preferably foam or sponge. Of course, particles of the above materials can also be used, so that multiple particles are filled in the inner cavity of the vertical rod 31. On the basis of reducing the weight of the vertical rod 3, when a collision or extrusion occurs, the side walls of the vertical rod 3 transmit the extrusion force through the internal elastomer 33, thereby reducing the possibility of deformation and damage of the vertical rod 3.

[0053] A further improvement is that the support column 11 includes a support tube 111 with an open top and a sealed bottom, and a cover body 112 that is detachably covered on the top of the support tube 111. The support tube 111 and the cover body 112 together form a filling cavity, which is used to inject a filling body to lower the center of gravity of the support column 11.

[0054] Specifically, such as Figure 7 and Figure 8 As shown, the support column 11 also includes a threaded tube 113, and a limit frame 114 is provided on the circumferential outer edge of one end of the threaded tube 113. The size of the cross-section of the circumferential outer edge of the limit frame 114 is consistent with the cross-section size of the circumferential outer edge of the support tube 111. The circumferential outer edge of the limit frame 114 is flush with the circumferential outer edge of the support tube 111, and the circumferential outer edge of the limit frame 114 is welded and fixedly connected to the top of the support tube 111. The threaded tube 113 is located on the inner side of the support tube 111; a threaded column threadedly connected to the threaded tube 113 is provided below the cover body 112.

[0055] After adopting the above structure, the support column 11 has a hollow structure, which further reduces the amount of production materials, lowers production costs, and reduces weight, making it easier to transport and install. During installation, a filler is injected into the interior of the support tube 111. It should be noted that the filler is preferably a fluid such as water, or fine yarn can also be used. The filler is allowed to settle to the bottom of the support tube 111, and then the threaded tube 113 is threadedly connected to the cover body 112 to seal the support tube 111. In this way, the fluid injected into the filling cavity lowers the overall center of gravity of the support column 11, making the support column 111 heavy at the bottom and light at the top, which is beneficial to the stability of the traffic guardrail structure.

[0056] A further improvement is that a positioning tube 13 is provided between the two mounting seats 12 corresponding to the two cross beams 2, and the circumferential inner walls at both ends of the positioning tube 13 are sealed with the circumferential outer edges of the two screw sleeves 44 respectively. The length of the positioning tube 13 is greater than the distance between the two screw sleeves 44 and less than the distance between the two mounting seats 12, so that the positioning tube 13 can slide on one side of the support column 11 along its own length direction, that is, the vertical direction.

[0057] After adopting the above structure, when assembling the column assembly 1 and the guardrail assembly, the two screw sleeves 44 are respectively inserted into the two ends of the positioning tube 13, and after aligning the rotating sleeves 21 at the same end of the two crossbeams 2 in the guardrail assembly and inserting them into the inner sides of the two mounting seats 12 on the same side of the support column 11, the positioning tube 13 is placed between the two mounting seats 12, and then the screw rod 43 and the rotating rod 41 are inserted, keeping the screw rod 43, the positioning tube 13, the first through hole 121, and the screw sleeve 44 coaxial, and tightening the screw sleeve 44 to the screw rod 43, so that the positioning tube 13 can be confined between the two mounting seats 12. After the traffic guardrail is installed, the positioning tube 13 is affected by gravity and slides downward until its bottom end abuts against the mounting seat 12 below, further lowering the overall center of gravity of the column assembly 1, thereby ensuring the stability of the traffic guardrail structure.

[0058] Obviously, the above embodiments are merely examples for clarity of explanation and are not intended to limit the implementation methods. Those skilled in the art will readily appreciate that other variations or modifications based on the above descriptions are possible. It is not necessary and impossible to enumerate all implementation methods here. Obvious variations or modifications arising therefrom remain within the scope of protection of the present invention.
