Self-adjusting double-layer road guardrail

Abstract

The invention belongs to the technical field of road safety, and discloses a self-adjusting double-layer road guardrail which comprises supporting frames, wherein a connecting part is fixedly installed on the side face of the supporting frame; the outer surface of the connecting part is movably sleeved with a damping part; the back face of the damping part is movably connected with a first guardrail; and the front face of the damping part is movably connected with a second guardrail. By arranging a sliding rods, a rectangular groove, a rectangular rod and the damping part, when the guardrails need to be disassembled and moved, a short rod is taken out of a notch firstly, then the rectangular rod is taken out of the rectangular groove, and then the first guardrail, the second guardrail and the damping part can rotate around the sliding rod integrally to between the opposite faces of two when the device is disassembled, the device rotates to the position between the opposite faces of the two supporting frames, then the rectangular rod drive the short rod to be inserted into the rectangular groove, and finally the short rod is inserted into the notch, so that the function of flexible disassembly of the road guardrail can be achieved.

Description

technical field [0001] The invention belongs to the technical field of road safety, in particular to a self-adjusting double-layer road guardrail. Background technique [0002] Highway fence is the most important transportation infrastructure. my country's expressway was developed in the 1980s. It plays an important role in the development of the national economy and society. It is an important maintenance and safety guarantee facility for expressways. At present, road construction personnel often install traffic road guardrails on both sides of the road in order to solve problems such as road traffic safety during road construction operations, and the existing road guardrails can indeed achieve diversion and improve safety when used. Problem, but in order to reduce the damage to people when vehicles hit the guardrail, the existing road guardrail usually uses a guardrail structure that is easily deformed after impact, thereby reducing the service life of the guardrail, so it...

Problems solved by technology

At present, road construction personnel often install traffic road guardrails on both sides of the road in order to solve problems such as road traffic safety during road construction operations, and the existing road guardrails can indeed achieve diversion and improve safety when used. Problem, but in order to reduce the damage to people when vehicles hit the guardrail, the existing road guardrail usually uses a guardrail structure that is easily deformed after impact, thereby reducing the service life of the guardrail, so it needs to be improved

[0003] The Chinese invention patent with the application number CN202020161777.7 discloses a double-layer anti-collision barrier for highway bridges. By setting the first protective plate and the second protective plate, the two-layer anti-collision barrier is located between the two protective plates on the surface of the fixed rod. The first elastic part is set, and when the anti-collision barrier is hit, the impact can be absorbed and buffered by the first elastic part, which greatly improves the stability of the anti-collision barrier and improves the safety of the bridge end of the expressway; but the invention Only the first elastic part absorbs and cushions the impact to a certain extent, and the cushioning effect is poor, which needs to be improved

[0004] The Chinese invention patent with the application number CN201810656683.4 discloses a new type of double-layer guardrail for expressways. By adopting the structure of the inner guardrail and the outer guardrail and adding a buffer spring between the two, the buffering effect of the guardrail is improved; but the The invention absorbs the impact through the buffer spring between the inner guardrail and the outer guardrail. The buffering effect is general and the inner guardrail and the outer guardrail cannot cooperate. It is necessary to further improve the interaction between the double-layer guardrails and improve the impact resistance. At the same time, it should have certain emergency measures after the guardrail is impacted, deformed or damaged, so it is necessary to further improve the existing double-layer highway guardrail
