Protective guardrail for municipal isolation

Abstract

The invention relates to the technical field of guardrails, in particular to a municipal isolation protective guardrail which comprises two frame bodies and a plurality of guardrail columns, protective rods are arranged in the guardrail columns, the top ends of the protective rods penetrate out of the guardrail columns, the height of the protective rods is adjusted through pop-up assemblies arranged in the guardrail columns, and sliding rods are horizontally arranged above the guardrail columns and located between the two frame bodies. Sliding blocks are arranged at the two ends of the sliding rod, sliding grooves are formed in the opposite side walls of the two frame bodies, and the sliding blocks longitudinally slide in the sliding grooves and adjust the height of the sliding rod; the height of a sliding rod is adjusted by releasing the elastic force of a second spring, when a pedestrian climbs over the guardrail, the height of the sliding rod is increased, at the moment, a protection rod can stretch out of a guardrail column under the elastic force of a pop-up spring, the height of the guardrail is integrally increased, the climbing difficulty of the pedestrian is further increased, and then the pedestrian is protected.

Description

technical field [0001] The invention relates to the technical field of guardrails, in particular to a protective guardrail for municipal isolation. Background technique [0002] Municipal road guardrail, also known as urban traffic galvanized plastic-sprayed steel guardrail, is suitable for urban traffic arteries and green belts in the middle of expressways, and is used to protect and protect personal safety and equipment and facilities in public places and other occasions. Some of the current Due to the low height of the isolation guardrail, pedestrians often climb over the guardrail, which endangers traffic and poses a very high safety hazard. [0003] The current conventional measure to prevent pedestrians from climbing over is to increase the height of the protective guardrail to increase the difficulty of pedestrians when they climb over. Another measure is to set the top of the guardrail as a sharp structure. When pedestrians see the sharp guardrail, they will be aware...

AI Technical Summary

Problems solved by technology

[0004] However, some problems are still exposed during the use of the above two guardrails. Increasing the height of the guardrail will increase the wind resistance of the guardrail and increase the swing at the top of the guardrail, which will affect the driving safety on the road. To a certain extent, it increases the difficulty of pedestrian climbing, but it will also cause climbers to stay in the guardrail area for a long time, causing pedestrians to stay on the road for a long time, which virtually increases the risk of pedestrians

[0005] However, if the top of the guardrail is set as a sharp structure, it will also cause the climbing pedestrians to be scratched. The guardrail itself is a facility for protecting pedestrians, but the method of increasing illegal costs prevents pedestrians from climbing over the guardrail, which deviates from the original design intention of the facility. , will also lead to citizens' distrust of municipal law enforcement and affect social management
