Description

Technical Field

[0001] The utility model relates to the technical field of guardrails, in particular to a set of movable guardrails for highway seasonal freezing areas. Background Technique

[0002] Guardrail - here refers to the industrial "guardrail" or collision guardrail, mainly used for the protection and safeguarding of equipment and facilities between factories, workshops and warehouses. Commonly made of steel, such as round steel pipes, square steel pipes or profiled steel plates. Surface treatment process: full-automatic electrostatic powder spraying (i.e., powder coating) or painting. The raw materials used for the surface treatment of outdoor anti-collision guardrails are waterproof materials. The anti-collision guardrails are made to be beautiful in appearance and not easy to rust.

[0003] After retrieval, a movable traffic guardrail with traffic signs disclosed in the Chinese utility model patent with the publication number CN214939698U includes a plurality of main brackets. A plurality of uniformly distributed sub-rods are fixedly connected inside the main brackets. Universal wheels are fixedly connected to the lower ends of the main brackets. A sliding groove is opened at the outer end of the lower side of the main brackets. An annular slider is slidably connected in the sliding groove. A cross plate is fixedly connected to the outer end of the annular slider. A bottom plate is arranged below the cross plate. A plurality of support columns are fixedly connected between the bottom plate and the cross plate. Through holes corresponding to the universal wheels are opened on the bottom plate. Two pairs of docking blocks are fixedly connected to the outer end of the lower side of the main brackets. A fixing device is arranged at the upper end of the cross plate. The fixing device includes a clamping plate, a rotating shaft and a clamping block. This solution can facilitate the movement of the traffic guardrail, save the movement time, and reduce the possibility of traffic congestion caused by the inconvenient movement of the traffic guardrail.
