[0026] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, rather than 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 efforts belong to the scope of protection of the present utility model.
[0027] Such as Figures 1 to 6As shown in the figure, a high-strength mobile guardrail includes a first anchoring bracket 1, a second anchoring bracket 2, an upper cross beam 41, a baffle group 42, and a support frame 3 arranged between the first anchoring bracket 1 and the second anchoring bracket 2; the upper cross beam 41 is respectively connected to the upper sides of the first anchoring bracket 1, the support frame 3, and the second anchoring bracket 2, and the baffle group 42 is installed on the sides of the first anchoring bracket 1 and the second anchoring bracket 2; both the first anchoring bracket 1 and the second anchoring bracket 2 are provided with anchoring components 5 for fixed installation, the first anchoring bracket 1 is further provided with a first docking component 6, the second anchoring bracket 2 is provided with a first docking structure 7, and the first anchoring bracket 1 cooperates with the first docking structure 7 on the second anchoring bracket 2 of another high-strength mobile guardrail through the first docking component 6 to realize the docking of two high-strength mobile guardrails. The utility model provides a high-strength mobile guardrail, which uses a first anchoring bracket, a second anchoring bracket, and a support frame to connect the upper cross beam and the baffle group arranged horizontally on both sides to form a single mobile guardrail, and then enables multiple mobile guardrails to be spliced and used through the first anchoring bracket and the second anchoring bracket that can be connected to each other to reach the required length. Moreover, there is a certain connection between multiple mobile guardrails to balance each other, preventing large displacements or damages when there is a local collision. In addition, the first anchoring bracket and the second anchoring bracket are directly installed on the ground through the anchoring components during use, greatly increasing the stability performance after installation.
[0028] By adopting the above structure, the length of a single mobile guardrail can reach 34.6 meters, which is suitable for use on long isolation belts on roads.
[0029] In this solution, two adjacent mobile guardrails are connected by docking the first anchoring bracket with the second anchoring bracket of another mobile guardrail. The structure can adopt that the first docking component 6 is a connecting pipe group, and the first docking structure 7 is a socket hole into which the connecting pipe group can extend. Of course, it can also be adopted that both the first docking component and the first docking structure are connecting pipes, and the splicing is completed by docking the two connecting pipes with each other.
[0030] Specifically, the first docking component 6 includes a first connecting pipe 61. A first docking hole 101 is provided on the first anchoring bracket 1. The first connecting pipe 61 is slidably disposed in the first docking hole 101, and a first retaining pin 91 is further provided on the first anchoring bracket 1 and extends into the first docking hole 101 to limit the movement of the first connecting pipe 61. A second retaining pin 92 is provided on the second anchoring bracket 2 and is inserted into the socket hole. The first retaining pin 91 and the second retaining pin 92 are used to limit the movement of the first connecting pipe 61. Before splicing, by removing or moving the first retaining pin 91, the first connecting pipe 61 can move relative to the first docking hole 101, so as to extend outwards and enter the socket hole. After splicing, the second retaining pin 92 is inserted into the socket hole to connect with the extending end of the first connecting pipe 61, thus completing the docking. Its structure is simple and the operation is convenient. Moreover, on the frontmost or rearmost moving guardrail, the first connecting pipe 61 can be completely retracted into the first docking hole 101 to keep its end from protruding.
[0031] In this solution, in order to increase the splicing strength, a group of connecting pipes is also added. Specifically, the first docking component 6 further includes a second connecting pipe 62. A second docking hole 102 is provided on the first anchoring bracket 1. The second connecting pipe 62 is slidably disposed in the second docking hole 102. The first retaining pin 91 can extend into the second docking hole 102 to limit the movement of the second connecting pipe 62, and the second connecting pipe 62 is located above the first connecting pipe 61.
[0032] In order to achieve better limiting and locking effects, a plurality of limiting holes 60 for the first retaining pin 91 and the second retaining pin 92 to be inserted are respectively provided on the first connecting pipe 61 and the second connecting pipe 62 along the length direction. The plurality of limiting holes are equivalent to multiple locking positions. It can be understood that the first retaining pin 91 is inserted into different limiting holes to limit the first connecting pipe 61 and the second connecting pipe 62 in different postures.
[0033] In this solution, the first anchoring bracket 1 is in the shape of being narrower at the top and wider at the bottom, and the two outer sides are respectively concave inclined surfaces or arcs. The anchoring component 5 is installed at the bottom of the first anchoring bracket 1. Moreover, the anchoring points are concentrated and located on both sides of the first anchoring bracket, which is convenient for drilling construction and saves the construction period. In addition, the bracket is designed with a small top and a large bottom structure, which effectively reduces the center of gravity of the guardrail, making the guardrail not easy to overturn during the collision process and increasing the collision protection ability. The two ends of the first anchoring bracket are designed with arc structures, so that the support frame of the guardrail will not insert into the road surface during the collision process, causing jamming and affecting the guardrail protection ability. In this solution, the first anchoring bracket is made of steel structure.
[0034] In this solution, the anchoring component 5 uses self-tapping screws. After use, it can be normally screwed out after removal, without leaving bolts in the roadbed, and there is no need to process the anchored road surface subsequently.
[0035] In the embodiment of the present utility model, the baffle group 42 is a double-wave plate and is respectively installed on the outer sides of the first anchoring bracket 1 and the second anchoring bracket 2. The guardrail in this solution is designed with a double-beam structure, and a double-wave plate is arranged in the middle, which not only ensures the strength of the guardrail but also has a good light-shielding effect, preventing the vehicle lights from interfering with the driving of the oncoming lane.
[0036] In addition, a number of profiling connectors 93 are provided on the two outer side surfaces of the first anchoring bracket 1, the second anchoring bracket 2 and the support bracket 3. The profiling connectors 93 are adapted to the inner side surface of the double-wave plate, and connectors are also provided at the overlapping positions of the double-wave plate and the profiling connectors 93. This effectively improves the connection strength and maintains the strength of the double-wave plate.
[0037] In this solution, the upper cross beam 41 is sleeved on the upper end of the first anchoring bracket 1, and the first pin 91 penetrates downward from the upper side of the upper cross beam 41. Its structure is simple and convenient for installation.
[0038] Moreover, vertical baffles 94 are provided between the first anchoring bracket 1 and the support bracket 3 and between the support bracket 3 and the second anchoring bracket 2. The vertical baffles 94 connect the upper cross beam 41 and the baffle groups 42 on both sides. This is applicable to the relatively long movable guardrail in this solution. In the length direction, multiple vertical baffles 94 are used to support the double-wave plates on both sides, effectively improving the strength.
[0039] The present utility model provides a high-strength movable guardrail, which uses a first anchoring bracket, a second anchoring bracket, and a support bracket to connect the upper cross beams and baffle groups arranged horizontally on both sides to form a single movable guardrail. Then, the first anchoring bracket and the second anchoring bracket that can be connected to each other are used to enable multiple movable guardrails to be spliced and used to reach the required length. Moreover, there is a certain connection between multiple movable guardrails to balance each other, preventing large displacements or damages from occurring during local collisions. In addition, the first anchoring bracket and the second anchoring bracket are directly installed on the ground through the anchoring components during use, greatly increasing the stability performance after installation.
[0040] It should be understood that in the present utility model, terms such as "first" and "second" are used to describe various information, but such information should not be limited to these terms, and these terms are only used to distinguish information of the same type from each other. For example, without departing from the scope of the present utility model, "first" information may also be referred to as "second" information, and similarly, "second" information may also be referred to as "first" information. In addition, the orientation or positional relationship indicated by terms such as "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present utility model.
[0041] The above is the preferred embodiment of the present utility model. It should be pointed out that for those of ordinary skill in the art, without departing from the principle of the present utility model, several improvements and modifications can be made, and these improvements and modifications are also regarded as the protection scope of the present utility model.
