Energy-absorbing type safety collision-proof fence of an expressway

Abstract

The invention relates to the technical field of highway, in particular to an energy-absorbing type safety collision-proof barrier of an expressway, including a base, the upper end of the base is symmetrically provided with a support column, the upper end of the supporting column is inserted with a rotating shaft, The outer side of the rotating shaft is hinged with upright posts, the lower side ofthe outer wall of the upright posts is provided with fixing rods, the opposite sides of the two upright posts are respectively provided with sliding grooves, the interior of the sliding grooves is slidably connected with a guard rail frame, the upper end and the lower end of the guard rail frame are fixedly connected with pull rings, and the interior of the guard rail frame is provided with a barbody. The invention is novel in structure and convenient in use, has good protection performance in the event of an accident, can effectively absorb the impact force of the automobile, greatly reducesthe reaction force of the automobile, reduces the harm caused by the accident, avoids the damage of the whole guardrail, prolongs the service life of the device, has strong practicability and is worth popularizing.

Description

technical field [0001] The invention relates to the technical field of highways, in particular to an energy-absorbing safety anti-collision guardrail for highways. Background technique [0002] Highway guardrails are generally blocking facilities set in parallel with the road. Its main function is to prevent traffic accidents caused by driver errors or other reasons that cause vehicles to cross the road or cross the central divider into the opposite lane. The driver and the occupants are safe, and at the same time, it can induce the driver's sight, increase the sense of driving safety and beautify the road environment. According to statistics, there are about 250 incidents of hitting the central guardrail on every 200 meters of expressway every year on average, which is three times as many as other types of traffic accidents on the expressway. [0003] At present, most of the safety guardrails on highways are made of steel or cement, and the structural design is simple. The...

Problems solved by technology

[0003] At present, most of the safety guardrails on expressways are made of steel or cement, and the structural design is simple. They are only in the shape of columns connected with cross bars. The reaction force is easy to cause a huge threat to the occupants of the vehicle, and the protective fence will also be damaged, causing safety hazards and short service life.
