Road construction safety guardrail

Abstract

The invention discloses a road construction safety guardrail, and relates to a road construction protection device. The guardrail comprises two bases, wherein the bases are provided with a pair of tracks, the tracks are connected to vertical columns, the lower ends of the vertical columns are fixedly connected with bottom plates, the lower surfaces of the bottom plates are connected with rolling wheels matched with the tracks, a guardrail body is connected between the two vertical columns, the guardrail body comprises connecting columns arranged at the two ends, a plurality of connecting frames are connected between the two connecting columns, adjacent connecting frames are rationally connected, the connecting frames are in an I shape, each connecting frame comprises connecting pieces arranged at the upper end and the lower end, a connecting rod is connected between the connecting pieces, and the outer surface of the connecting rod is rotationally connected with a protection plate. Thelength of the guardrail can be adjusted by increasing or decreasing the number of the connecting frames, and angles between every two adjacent connecting frames can be adjusted, so that the guardrailcan be suitable for protection of roads with different bending degrees, and the protection effect is improved.

Description

technical field [0001] The invention belongs to the technical field of road construction protection equipment, in particular to a road construction safety protection fence. Background technique [0002] The road construction guardrail plays a good role in isolating and protecting the construction site during the road construction process. At the same time, it can be used to play a good warning role for passing vehicles and pedestrians. It is generally widely used in the isolation and warning of construction sites. The existing The structure of the road construction guardrail is simple and easy to be blown down by the wind, and the existing construction guardrail is usually a continuous connection between the column and the guardrail. The size of the guardrail is fixed, and most of them are planar structures. For road protection, when the road turns or detours, the guardrails are usually arranged at right angles, and cannot be placed along the corners of the road in a relaxed...

Problems solved by technology

[0003] The object of the present invention is to provide a road construction safety guardrail with adjustable length and suitable for curve protection. Connecting columns are connected by rotating on the uprights, and there are several connecting frames connected between the connecting columns. The rotating connection solves the technical problem that the length of the existing guardrail is fixed and is not suitable for curve protection
