Abstract

The invention discloses a road guardrail buffer device for coal mine safety in the technical field of road guardrail, the right side of the rigid adjusting device is provided with a concave plate, a concave groove is arranged on the right side of the concave plate, a limited block is arranged at the left end of the concave groove, a limited cylinder is arranged on the right side of the limited block, a connecting rod is sleeved on the right side of the limited cylinder, a convex block is arranged at the right end of the connecting rod, a compression spring matched with the limited cylinder isarranged between the limited block and the convex block, and the compression spring is sleeved on the outer wall of the limit cylinder and the connecting rod, the right side of the convex block is provided with a buffer column, the right end of the buffer column is provided with an anti-C template, the right side of the anti-C template is provided with a wave-shaped plate. The rigid adjusting device can adjust the rigidity of the guardrail according to the danger level of the road to improve the anti-collision grade of the guardrail and increase the buffer performance of the guardrail, and theright end buffer device of the rigid adjusting device further improves the buffer performance.

Description

technical field [0001] The invention relates to the technical field of road guardrails, in particular to a road guardrail buffer device for coal mine safety. Background technique [0002] With the rapid development of traffic, in the process of coal mine transportation, on the one hand, the drug actively prevents the occurrence of traffic accidents, on the other hand, when traffic accidents occur, the harm should be minimized as much as possible, such as the setting of safe lanes and guardrails Wait. [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, but the guardrails currently used do not have good cushioning performance , it is impossible to reduce the impact force generated by the collision when the driving and the guardrail collide, and it is not convenient to use, and the anti-collision level of the guardr...
