Protective fence with anti-crossing function for municipal engineering

Abstract

The invention relates to the field of municipal engineering, and aims to provide a protective fence with an anti-crossing function for municipal engineering; the protective fence comprises a lower protective fence body and an upper protective fence body, the lower protective fence body comprises a first stand column and a second stand column, a first base is welded to the bottom end of the first stand column, and a second base is welded to the bottom end of the second stand column. The protective fence has the beneficial effects that the lower protective fence body and the upper protective fence body are matched for use, so that the municipal engineering protective fence has a very good anti-crossing function, insertion plates are inserted into insertion grooves, connection between the protective fence bodies is more compact and stable, and through matched use of cylinders, forward threaded rods and reverse threaded rods, the cylinders drive the forward threaded rod and the reverse threaded rod to rotate in the adjusting screw holes, so that the distance between the lower protective fence body and the upper protective fence body can be adjusted according to needs, and the anti-crossing effect of the protective fence is further improved.

Description

technical field [0001] The invention relates to the field of municipal engineering, in particular to a protective fence for municipal engineering with the function of preventing overturning. Background technique [0002] Municipal road guardrail is also called urban traffic galvanized plastic-sprayed steel guardrail. It is beautiful, novel, easy to install, safe and reliable, and the price is favorable. It is suitable for urban traffic arteries, green belts in the middle of expressways, bridges, secondary roads, township roads and various roads. Separation of toll gates, etc. [0003] Through inspection office, Chinese Patent No. CN211973276U provides a kind of municipal road with a protective fence to prevent pedestrians from climbing over. [0004] It includes a left support pile and a right support pile, the bottom of the left support pile and the right support pile are provided with a fixing device, and the top of the left support pile is fixedly connected with a top pl...

AI Technical Summary

Problems solved by technology

The municipal road has a protective fence to prevent pedestrians from climbing over. Through the cooperation between the rotating shaft and the roller, when the pedestrian wants to climb over the protective fence and step on the surface of the roller, the roller will rotate, so that pedestrians cannot climb up through the protective fence. Climb, set rollers on the right side of the roof, so that pedestrians cannot get upward traction by grabbing the guardrail, so that pedestrians cannot climb over the device

[0005] However, road guardrails can only hinder vehicles, causing many pedestrians to cross the road and cross the guardrails in order to save time, which affects normal traffic order and easily causes traffic accidents. At the same time, the guardrail does not have an anti-collision structure, and its impact resistance is poor, which is not conducive to promotion and popularization
