Warning protection device for pavement maintenance engineering

Abstract

The invention discloses a warning protection device for pavement maintenance engineering. The warning protection device comprises a bottom plate (1), side edge supporting rods (2), sliding block rods (4), a hanging assembly, a fixing frame (5), a bottom rotating assembly, a warning panel assembly and a positioning assembly; the side edge supporting rods are installed on the bottom plate to form inverted-T-shaped supporting base structures, and the bottom plate is installed on the ground through the positioning assembly; sliding grooves (3) are formed in the side edge supporting rods, one end of each sliding block rod is connected with the fixing frame and the sliding grooves, and the fixing frame is arranged between the pair of inverted-T-shaped supporting base structures through the pair of sliding block rods to form a protection device body; the hanging assembly is embedded in the sliding grooves, and the sliding block rods are connected with the hanging assembly and bounce along the sliding grooves; and the bottom of the fixing frame is rotationally connected with the side edge supporting rods through the bottom rotating assembly, and the warning panel assembly is installed in the fixing frame. According to the warning protection device, rotation and rapid resetting of the fixing frame can be achieved, the situation that external force loads are transmitted to the inverted-T-shaped supporting base structures, and consequently the stability of the protection device body is influenced is avoided, and the effective protection effect is guaranteed.

Description

technical field [0001] The invention relates to a municipal engineering auxiliary equipment, in particular to a warning and protection device for road surface maintenance engineering. Background technique [0002] The road surface 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 safety, comfort and smoothness of driving, and save transportation costs and time. In order to avoid unnecessary potential safety hazards for pedestrians and vehicles in the construction area, guardrails are usually used to fence the construction area during road surface maintenance projects. [0003] Most of the guardrails in the prior art are plate-shaped 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 s...

AI Technical Summary

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
