Problems solved by technology

The existing traffic guardrails can basically meet the above requirements, but there are still some shortcomings. For example, when a vehicle hits the guardrail, the guardrail often cannot be automatically disconnected, which increases the number of damaged guardrails and increases the workload of traffic guardrail repair. Some guardrails have complex structures and high production costs. The market needs a traffic guardrail that can reduce costs, has a simple structure, and is easy to install and apply.

Abstract

The invention discloses an adjustable type traffic guardrail. The adjustable type traffic guardrail comprises a base, main stand columns and a protection frame, wherein the base is in bolt connection with the main stand columns; fixed lugs are arranged on the two sides of each of the main stand columns; top plates are arranged in the fixed lugs; clamping blocks are arranged on the top plates and are semi-spherical; the protection frame comprises transverse beams, vertical beams, grid plate base plates and grid plates; one side, close to the main stand columns, of each vertical beam is provided with iron plates corresponding to the positions of the fixed lugs; fixed holes are formed in the iron plates; the protection frame is arranged in the fixed lugs by the iron plates to be movably connected with the main stand columns; a slide way is arranged on the side wall of the lower part of each main stand column and a bayonet is arranged at the side part of each slide way; universal wheel adjusting rods are arranged in the slide ways; adjusting transverse rods are arranged on the universal wheel adjusting rods; universal wheels are arranged at the lower parts of the universal wheel adjusting rods. According to the adjustable type traffic guardrail, the traffic guardrail is easier to break after being fiercely impacted and the whole guiderail is prevented from large-area displacement; the maintenance difficulty is reduced and the installation is more convenient; the damage state of the traffic guiderail can be monitored and the traffic guiderail can be maintained in time.

Description

technical field [0001] The invention relates to the technical field of traffic guardrails, in particular to an adjustable traffic guardrail. Background technique [0002] The traffic guardrail has a variety of functions. First, the separation function. The traffic guardrail separates motor vehicles, non-motor vehicles and pedestrian traffic, so that motor vehicles, non-motor vehicles and pedestrians can travel in separate lanes, which improves road traffic safety and ensures traffic order. Improved road utilization. The traffic barrier is followed by a blocking function. The traffic barrier will block possible bad traffic behaviors and block pedestrians, bicycles or motor vehicles attempting to cross the road. According to the function of the traffic guardrail, it needs to have a certain height, certain density, and necessary strength. The third function of the traffic guardrail is the warning function. The form of the guardrail should be simple to warn traffic participant...
