Problems solved by technology
[0004] The purpose of the present invention is to provide a protective barrier with an energy-absorbing device for alleviating road collisions, so as to solve the problem that the protective barrier proposed in the above background technology only plays the role of isolation. When a car hits the protective barrier, the protective barrier will not only fail Play a protective role, and even often cause harm to pedestrians or other vehicles, and then cause secondary accidents

The invention discloses a guardrail with an energy absorbing device for alleviating road collisions, relates to the field of guardrails, and includes a railing frame, on which a rotating frame is rotatably installed, and an impact plate is provided on one side of the rotating frame. The first shaft is rotatably installed on the railing frame, the second shaft and the third shaft are fixedly installed on the railing frame, three first rollers are fixedly installed on the first shaft, and three rollers are installed on the second shaft and the third shaft. a second roller and a third roller. In the present invention, through the setting of the railing frame, the rotating frame, the impact plate, the third shaft, the second shaft, the first shaft, the third roller, the second roller, and the first roller, when the vehicle runs out of control and crashes into the protective railing on the road , the trigger device drives the energy-absorbing device into the preset position, and the guide device guides the vehicle to collide with the energy-absorbing device. Most of the kinetic energy in this process will be absorbed by the energy-absorbing device, thereby reducing the damage of the vehicle and the occupants. casualty rate.
Description
technical field [0001] The invention relates to the technical field of guardrails, in particular to a guardrail with an energy-absorbing device for alleviating road collisions. Background technique [0002] Guardrail, also known as urban traffic galvanized plastic-sprayed steel guardrail, it is beautiful, novel, easy to install, safe and reliable, and the price is favorable. Separation of toll gates, etc. [0003] In the prior art, the guardrail only plays the role of isolation. When the car hits the guardrail, the guardrail will not only fail to protect the car, but will cause serious damage to the vehicle, and even cause casualties to the people in the car. Other vehicles cause injuries, which in turn cause secondary accidents. Therefore, a protective barrier with an energy-absorbing device for alleviating road collisions is needed to meet people's needs. Contents of the invention [0004] The purpose of the present invention is to provide a protective fence with an en...
