The invention discloses a cement pier road transportation trailer with an emergency danger avoiding function. The cement pier road transportation trailer comprises a road emergency brake cargo limiting and fixing device, a combined upper end shielding device and a road transportation trailer body mechanism. The invention belongs to the technical field of road transportation trailers, and particularly relates to a cement pier road transportation trailer with an urgent danger avoiding function. The characteristic that the density of liquid is larger than the density of air is utilized to reduce the potential energy of forward movement generated when goods are braked suddenly, the Pascal's law is utilized to convert the potential energy of the forward movement of the goods into movement kinetic energy which extends from the side edge and increases resistance to the side edge of the goods, and the movement distance of the goods is further reduced under the condition that a truck is braked suddenly; through the layer-by-layer decreasing type shielding plates formed by combining and splicing the upper ends and the arc-shaped flow guide plates at the front ends, the Bernoulli air flow guide characteristic is achieved, the probability that water and dust are accumulated on the surface of the trailer is reduced, and therefore the safety of the trailer under the emergency braking condition is guaranteed.
本发明公开了具有紧急避险功能的水泥墩道路运输挂车,包括道路急刹货物限位固定装置、组合式上端遮挡装置和道路运输挂车车体机构。本发明属于道路运输挂车技术领域,具体是指具有紧急避险功能的水泥墩道路运输挂车;本发明首先利用液体密度大于空气密度的特点,降低货物急刹时产生的向前移动的势能,利用帕斯卡定律,将货物向前移动的势能转化为侧边延伸、并对货物的侧边进行增加阻力的移动动能,进一步降低货车急刹条件下,货物的移动距离;通过上端组合拼接而成的逐层递减式的遮挡板,以及前端的弧形导流板,顺势实现伯努利空气导流特性,降低了遇水和尘土在挂车表面积聚的几率,以此保证了挂车在急刹条件下的安全性。
