Buffer protection system for highway bridge
The buffer protection system for the highway bridge comprises a protection seat and a ramp guardrail, movable grooves are formed in the two sides of the protection seat, protection plates are arranged in the movable grooves, pin shafts are arranged between the protection plates and the protection seat in a penetrating mode, a protection frame is arranged on one side of each protection plate, and the protection frame is arranged on the other side of the protection seat. A rotating shaft is arranged in the protection frame in a penetrating mode, the outer side of the rotating shaft is sleeved with a buffering roller, a connecting base is installed on the outer side wall of the protection plate, and a supporting column is connected to the side, close to the protection plate, of the protection frame. By arranging the buffering air bag, the buffering roller and the pin shaft, buffering, force unloading and protection can be continuously carried out on a collided vehicle, and the ramp guardrail and the vehicle are bidirectionally protected; by arranging the locking part, on one hand, the vehicle can be limited from turning upwards through the limiting effect of the locking part, on the other hand, the buffering part is transferred to be pressed, the situation that the buffering air bag is excessively pressed to be broken due to automobile collision is avoided, and the service life of the buffering air bag is prolonged.
本发明公开了一种公路桥梁用缓冲防护系统，包括防护座与匝道护栏，所述防护座两侧均开设有活动槽，所述活动槽内部设置有防护板，所述防护板与防护座之间贯穿设置有销轴，所述防护板一侧设置有防护架，所述防护架内贯穿设置有转轴，所述转轴外侧套设有缓冲滚筒，所述防护板外侧壁安装有连接座，所述防护架靠近防护板的一侧连接有支柱。本发明通过设置缓冲气囊、缓冲滚筒与销轴，可以达到实现连续对冲撞车辆进行缓冲、卸力以及防护，双向保护匝道护栏与车辆；通过设置抱死部，可以达到一方面由抱死部的限位作用限制车辆向上翻起，另一方面转移缓冲部受压，避免受汽车冲撞造成缓冲气囊受压过重发生破裂的情况，延长缓冲气囊的使用寿命。
