Description

Technical Field

[0001] The utility model relates to the technical field of road protection, in particular to a bridge pavement protection fence. Background Art

[0002] Bridge pavement guardrails are protective facilities installed on both sides or along roads and bridges. They are mainly used to prevent vehicles from deviating from the road or falling into the river under the bridge and other dangerous situations.

[0003] However, accidents are inevitable when vehicles are driving. When a vehicle collides with a bridge pavement guardrail and causes it to be damaged, the staff needs to remove the damaged part of the bridge pavement guardrail, and then formulate a specific repair plan based on the damage; including replacing damaged parts, repairing cracks, reinforcing joints or repainting, etc.; during this period, the staff will use temporary guardrails to replace the removed part of the bridge pavement guardrail to provide temporary protection.

[0004] A Chinese patent with publication number CN208563193U proposes a temporary guardrail for a traffic road that is easy to store. The temporary guardrail is formed by combining multiple guardrail units, and the angle between two adjacent guardrail units is adjustable. In addition, the length of each guardrail unit can be adjusted to meet usage requirements while being easy to store.

[0005] Although the above technical solution can connect multiple guardrail units to form a temporary guardrail, it cannot be connected to the bridge pavement guardrail body in actual use. In addition, the movable rollers at the bottom make it extremely unstable when used and can only serve as a temporary warning. It will be displaced or collapsed after a slight collision and has no substantial protective effect.

[0006] As is known from the above, the prior art obviously has inconveniences and defects in practical use, so it is necessary to improve it. Utility Model Content

[0008] In order to achieve the above-mentioned purpose, the utility model provides a bridge road protection barrier, comprising: a first pillar, a second pillar and a scissor rod group;

[0009] The side walls of the pillars 1 and 2 are both installed with buckle assemblies; the buckle assemblies include two mounting plates arranged opposite to each other, the inner walls of the two mounting plates are each provided with an avoidance groove, the inner bottoms of the two avoidance grooves are each connected with an elastic member group, and the free ends of the two elastic member groups are each connected with a limit plate;

[0010] One end of the scissor rod group is connected to the first support column, and the other end is connected to the second support column.

[0011] According to the bridge pavement guardrail described in the utility model, the top of the first pillar is connected with a thorn wire, and the free end of the thorn wire extends to the top of the second pillar and is connected to the second pillar.

[0012] According to the bridge pavement guardrail described in the utility model, the spines are made of a metal material with a high elastic limit.

[0013] According to a bridge pavement guardrail described in the utility model, the pillar one and the pillar two are both composed of a lower pillar and an upper pillar sleeved on the top of the lower pillar; and a driving member is embedded in the top of the lower pillar of the pillar one, and the output shaft end of the driving member is connected to the inner bottom of the upper pillar.

[0014] According to a bridge pavement guardrail described in the utility model, the side wall of the second pillar is rotatably connected with a rotating rod, and the side wall of the first pillar is provided with a limiting column at the same height as the rotating rod; the end of the rotating rod is provided with a notch adapted to the limiting column.

[0015] According to the bridge pavement guardrail described in the utility model, a side of the limiting plate away from the mounting plate is provided with an arc.

[0016] According to the bridge pavement guardrail described in the utility model, universal wheels are installed at the bottom of the first pillar and the second pillar.

[0017] The utility model provides a bridge pavement guardrail, which has the following beneficial effects:

[0018] 1. By using the buckle assembly to quickly install the pillars one and two at the missing part of the bridge pavement guardrail, the damaged part of the bridge pavement guardrail can be temporarily replaced for effective protection.

[0019] 2. By setting up thorns, pedestrians can be prevented from climbing over and the incidence of accidents can be reduced.

[0020] 3. The overall protection height of the guardrail can be adjusted by driving the upper support to increase, so that the height of the guardrail can adapt to the guardrails of bridges and road surfaces of different heights, ensuring that the guardrail is highly adapted to the guardrails of bridges and road surfaces, and having a higher aesthetic appearance.

[0021] 4. The use of the rotating rod and the limit column can prevent the guardrail from being accidentally opened after being folded, making it easier to carry. BRIEF DESCRIPTION OF THE DRAWINGS
