The invention discloses a road protective fence capable of assisting in forcibly stopping by collision and relates to the traffic field. The road protective fence comprises a protective guard, a roadmain body and a roadbed; the protective guard comprises a limiting column, a segmented groove, an adaptive groove, a bottom fixing block, a top fixing block and a handrail arc block; the limiting column is an arc-shaped cylinder with the wide upper portion, the wide lower portion and the narrow middle portion. According to the road protective fence capable of assisting in forcibly stopping by collision, the protective guard is made to move towards the rear side under the collision extrusion force of a vehicle, and when the protective guard moves towards the rear side, the protective guard canbe contracted through the telescopic rods; meanwhile, adaptive extrusion cushion block at the bottoms of retracting rods on the telescopic rods extrude each other, the limiting force during vehicle collision is improved through corresponding extrusion of the cambered surfaces; and the adaptive counter-braking springs are synchronously contracted under the vehicle collision, and the adaptive counter-braking springs and the handrail arc blocks are matched to perform counter-braking force on the vehicle; therefore, the effect of counteracting vehicle impact to timely control the vehicle to perform auxiliary forced stop is achieved.
本发明公开了一种可冲撞辅助强制迫停的道路防护栏，涉及交通领域，该一种可冲撞辅助强制迫停的道路防护栏，包括护栏、道路主体和路基，护栏包括限制柱、分段槽、适变槽、底固定块、顶固定块和扶手弧块，其中限制柱为上下宽中间窄的弧形圆柱状，在本发明中，该可冲撞辅助强制迫停的道路防护栏，从而使得护栏受车辆冲撞挤压力向后侧进行移动，当护栏向后侧进行移动时，护栏会通过伸缩杆进行收缩，同时伸缩杆上收杆底部的适配挤压垫块会相互挤压，通过弧面对应挤压提高车辆冲撞时限制力，同时适配反制弹簧受车辆冲撞进行同步收缩，配合多组适配反制弹簧和扶手弧块对车辆进行反制力，从而达到反制车辆冲击及时控制车辆进行辅助迫停的效果。
