Protective barrier for road and bridge safety
The invention belongs to the technical field of road construction, and relates to a protective barrier for road and bridge safety, which is characterized by comprising a main body, a buffer plate and plugs, a plurality of empty cylinders are uniformly arranged on the main body, one end of each empty cylinder is provided with an opening, and the other end is sealed; a plurality of through holes are formed in the sealing end faces of the hollow cylinders; a second spring is fixedly arranged on the inner wall of each through hole, and the tail end of each second spring is fixedly connected with the plug. pistons are slidably arranged in the hollow cylinders, and piston rods are fixedly arranged on the pistons; the buffer plate is elastically arranged at the other end of the piston, and a first spring is fixedly arranged between the buffer plate and the main body. When a vehicle accidentally collides with the protective barrier, the kinetic energy of the vehicle can be converted into elastic potential energy of the first spring and heat energy generated by friction between the piston and the side wall of the empty cylinder through the first spring and the piston, and the vehicle is buffered. The damage to people in the vehicle caused by accidents is reduced, and the damage to a construction site can be greatly reduced when the vehicle is collided.
本发明属于道路施工技术领域，一种用于道路桥梁安全的防护栏杆，其特征在于，包括主体、缓冲板及堵头；主体上均匀设置有多个空筒，空筒的一端设置有开口而另一端密封；空筒的密封端面上开设有多个通孔；通孔的内壁上固定设置有弹簧二，弹簧二的末端和堵头固定连接；空筒内滑动设置有活塞，活塞上固定设置有活塞杆；缓冲板弹性设置于活塞的另一端，缓冲板和主体之间固定设置有弹簧一。在车辆发生意外撞击防护栏杆时，弹簧一与活塞的设计将会使汽车的动能转化为弹簧一的弹性势能及活塞与空筒侧壁摩擦的热能，对车辆进行缓冲。减小因意外而对车内人员的伤害，并且可以在车辆撞击时可以极大程度减少对施工现场的破坏。
