Warning and protection device for road surface maintenance engineering

Abstract

The invention discloses a warning protection device for road surface maintenance engineering, which comprises a bottom plate (1), a side support bar (2), a slider bar (4), a hanging assembly, a fixed frame (5), a bottom rotating assembly, and a warning Panel assembly and positioning assembly; the side support bar is installed on the bottom plate to form an inverted T-shaped support seat structure, and the bottom plate is installed on the ground through the positioning assembly; there is a chute (3) on the side support bar, and one end of the slider bar is connected to the fixed frame And the chute, the fixed frame is set between a pair of inverted T-shaped support seat structures through a pair of slider rods to form the main body of the protective device; the hanging component is embedded in the chute, and the slider rod is connected with the hanging component Bouncing; the bottom of the fixed frame is rotatably connected to the side support rod through the bottom rotating component, and the warning panel component is installed in the fixed frame. The invention can realize the rotation and quick reset of the fixed frame, avoid the external force load being transmitted to the inverted T-shaped support seat structure and affect the stability of the protection device body, and ensure effective protection effect.

Description

technical field [0001] The invention relates to municipal engineering auxiliary equipment, in particular to a warning protection device for road maintenance engineering. Background technique [0002] The road maintenance project is to maintain and maintain the road, maintain the road and the structures and facilities on the road, maintain the performance of the road as much as possible, restore the damaged part in time, ensure the driving safety, comfort and smoothness, and save the transportation cost and time. In order to avoid unnecessary safety hazards to pedestrians and vehicles in the construction area, protective fences are usually used to fence the construction area during road maintenance works. [0003] Most of the guardrails in the prior art are of plate-like or fence-like structures and are supported at the construction area through a base, and have poor stability. When subjected to harsh environments such as collisions or strong winds, the guardrails are prone t...

Problems solved by technology

[0003] Most of the guardrails in the prior art are plate-like or fence-like structures and are supported at the construction area through the base, which has poor stability. When subjected to harsh environments such as collisions or strong winds, the guardrails are easy to topple over, affecting the protection effect

At the same time, there are usually warning slogans or fluorescent strips on the surface of the guardrail to increase the eye-catching effect, but the warning effect is not good in places and time periods with poor light, and the warning content is single and cannot be replaced, so it cannot be flexibly used in various construction situations
