Embodiment 1

[0018] Embodiment 1, a highway guardrail, comprising a lower crossbar 2 and an upper crossbar 1, both of which are horizontally placed bar-shaped structures, and a lower crossbar 2 is formed on the upper surface along the length direction of the bar. Horizontal groove 3, the upper crossbar 1 is installed in the horizontal groove 3 and can slide up and down in the horizontal groove 3, a compression spring 4 is installed between the bottom of the horizontal groove 3 and the bottom surface of the upper crossbar 1; each side of the lower crossbar 2 is installed There is a side wing plate 5 parallel to it, the upper part of each side wing plate 5 is hinged with the side wall of the lower cross bar 2, and each side wing plate 5 is fixedly connected with a gear 6 that can rotate around its hinged side, and the upper cross bar 1 There is a vertical rack 7 on the side wall of the rack, the inner side of the gear 6 cuts into the horizontal groove 3 and meshes with the rack 7 on the corre...

Embodiment 2

[0019] Embodiment 2, on the basis of Embodiment 1, a plurality of water storage grooves 8 are provided on the bottom surface of the horizontal groove 3, and a plurality of water storage grooves 8 are arranged on the bottom surface of the upper cross bar 1. Each raised block 9 has a vertical through hole 10, and the downward movement of the upper cross bar 1 will press the raised block 9 into the water storage groove 8 below it, so that the storage The water in the water groove 8 is squeezed and sprayed from the upper surface of the upper cross bar 1 through the through hole 10 .

Embodiment 3

[0020] Embodiment 3, on the basis of Embodiment 1, a support leg 11 is provided at both ends of the lower cross bar 2, and a horizontal connecting rod 12 is connected between the lower ends of the two support legs 11. A plurality of vertical grids 13 are evenly distributed between the legs 11, the upper end of each grid 13 is connected with the lower cross bar 2, and the lower end is connected with the connecting rod 12, and the plurality of grids 13 form a railing-like structure.

Abstract

The invention relates to a highway guardrail. The currently ubiquitous problem that pedestrians cross over a guardrail is effectively solved. According to the technical scheme, the highway guardrail comprises a lower cross bar and an upper cross bar. The two cross bars are each of a horizontally and transversely arranged bar-shaped structure. A transverse groove is formed in the upper surface of the lower cross bar in the bar length direction. The upper cross bar is installed in the transverse groove and can slide up and down in the transverse groove. Compressed springs are installed between the bottom of the transverse groove and the bottom face of the upper cross bar. The two sides of the lower cross bar are each provided with a side wing plate parallel to the lower cross bar. The upperportion of each side wing plate is hinged to the side wall of the lower cross bar. Each side wing plate is fixedly connected with a gear capable of rotating around the hinging edge of the side wing plate. Vertical racks are arranged on the side walls of the upper cross bar. The inner sides of the gears cut in the transverse groove to be engaged with the racks on the corresponding sides of the gears. The lower cross bar is pressed downwards so that the gears can be driven by the racks to rotate, the gears drive the side wing plates to rotate around the hinging edges of the side wing plates, andtherefore the two side wing plates are expanded. The highway guardrail is ingenious in structure, capable of effectively preventing guardrail crossing behaviors and high in practicability.

Description

technical field [0001] The invention relates to the field of public facilities, in particular to a highway guardrail. Background technique [0002] On the current urban highways, guardrails are often installed in the middle of the road to isolate two-way traffic flow. Road guardrails play a very important role in guiding and guiding traffic and ensuring vehicle safety; the height of such guardrails is generally around 1.2m. However, for convenience, some pedestrians arbitrarily climb over the protective fence in the middle of the road, which brings great hidden dangers to traffic safety. Effectively preventing pedestrians from overriding at will, maintaining traffic order, and ensuring the safety of driving and pedestrians have become serious problems to be solved urgently by relevant departments. Increasing the height of the guardrail, although it can increase the difficulty of climbing over, seriously affects the driving sight and the beauty of the road, and if the fence ...
