An anti-collision guardrail alarm device based on force pressing principle

Abstract

The invention relates to the technical field of guardrail protection, and discloses an anti-collision guardrail alarm device based on a force pressing principle. A pressing spring and a connecting rod are movably connected to the outer side of the pressing spring, a pressing plate is movably connected to one end of the pressing spring away from the mounting block, and a supporting spring and a trigger rod are movably connected to one end of the pressing plate that is far away from the pressing spring. The anti-collision guardrail alarm device based on the pressing principle of force, by installing the guardrail body on the construction site or other construction sites, when the guardrail body is severely collided, the buffer rod is bent, and the buffer rod pulls the buffer spring connected to the outside. . The buffer worm is bent and stretched with the buffer axis as the support point, and the impact force of the guardrail body is buffered and removed, so as to avoid the damage to the guardrail body caused by the rigid impact.

Description

technical field [0001] The invention relates to the technical field of guardrail protection, in particular to an anti-collision guardrail alarm device based on the force pressing principle. Background technique [0002] Guardrails can be seen everywhere in life, and are widely used in the maintenance of municipal engineering, transportation, communities, ports, airports, and storage areas. The development of guardrail products is becoming more and more mature, and the scale is expanding and the styles are increasing. Guardrails are divided by materials, mainly iron guardrails, stone guardrails, plastic guardrails, wooden guardrails, cement guardrails, etc. According to their functions, they are divided into balcony guardrails, stair guardrails, air-conditioning guardrails, community guardrails, anti-theft guardrails, stadium guardrails, etc. [0003] Guardrails are widely used in daily life. In the construction site, guardrails are needed to divide the construction zone, pre...

AI Technical Summary

Problems solved by technology

[0003] Guardrails are widely used in daily life. In the construction site, guardrails are needed to divide the construction zone, prevent unrelated personnel from entering the construction site, and protect the construction site and other unrelated personnel. There are often many projects in the construction site. Vehicles or staff's private cars come in and out, and the construction site environment is complex, and some vehicles will inevitably collide with the guardrail; when the existing building guardrail is in use, those vehicles that collide with the guardrail will have a large gap between the guardrail and the guardrail. impact force, so that the guardrail will be damaged, and it will cause damage to the vehicle. The existing building guardrail has a poor anti-collision effect when it is used. There is no buffer zone, and the rigid impact generated during the collision is too large, which is inconvenient. The use of users reduces the practicability of building guardrails
