Abstract

The invention discloses a road guard railing buffer device in the technical field of road guard railings. A concave plate is arranged on the right side of a rigid adjusting device, a groove is formedin the right side of the concave plate, a limit block is arranged at the inner left end of a cavity of the groove, a limit cylinder is arranged on the right side of the limit block, a connecting rod is inserted into the right side of the limit cylinder, a convex block is arranged at the right end of the connecting rod, a compression spring matched with the limit cylinder is arranged between the limit block and the convex block and sleeves the outer walls of the limit cylinder and the connecting rod, a buffer post is arranged on the right side of the convex block, a reverse C-shaped plate is arranged at the right end of the buffer post, a wavy plate is arranged on the right side of the reverse C-shaped plate, the rigidity of the guard railings can be adjusted according to the danger level of a road by the rigid adjusting device to improve the anti-collision level of the guard railings and enhance the buffer performance of the guard railings, and the buffer performance is further improved by the buffer device at the right end of the rigid adjusting device.

Description

technical field [0001] The invention relates to the technical field of road guardrails, in particular to a buffer device for road guardrails. Background technique [0002] With the rapid development of traffic, expressways give us great convenience. However, the accompanying traffic safety problems cannot be ignored. Responding to traffic accidents mainly starts from two aspects: on the one hand, proactively prevent traffic accidents, such as vigorously popularizing the formulation of corresponding traffic regulations and the compliance of drivers with safe driving laws, as well as the establishment of traffic signs; on the other hand, when traffic accidents occur, When it happens, try to minimize its hazards, such as avoidance lanes, setting of guardrails, etc. [0003] At present, the guardrail is the most common traffic safety facility in practice, which helps to reduce the occurrence of single-vehicle accidents and reduce the occurrence of damage to people and vehicles...
