Description

防撞防越界圆柱万向球体墙 技术领域
本发明一种防撞防越界圆柱万向球体墙，用于公路、高速公路、桥梁、隧道等易发生交通事故路段，阻止失控车辆越出界线，防止重大事故的发生。
背景技术
目前，作为一种道路安全防护手段，我国及其它国家公路、高速公路两侧及中间都使用护栏板，桥梁和隧道基本使用水泥阶梯防护墩，桥梁上一般会加上一些扶手。上述防护装置，对于低速行驶的失控车辆有一定的防护和保护作用，但对于高速行驶的失控车辆，防护板的耐冲击性不堪一击，桥梁和隧道的水泥阶梯防护墩也无法阻止高速车辆事故的发生。每年全世界在公路、高速公路、桥梁、隧道行驶的失控车辆因没有完全阻挡车轮机构，造成大量人员伤亡和财产损失。
发明内容
为了解决现有技术存在的上述问题，本发明提供一种防撞防越界圆柱万向球体墙，其安装在公路、高速公路、桥梁、隧道等事故多发路段，可依据现场条件设置，可以有效防止失控车辆、车速过快撞击到防护栏，同时车辆前部及前轮与防撞防越界万向球体墙接触，防撞防越界圆柱万向球体墙能够阻挡和吸收失控车辆的动能，并与车的行进方向车轮的转向作相对和万向运动，从而保证车轮不会越界防撞防越界圆柱万向球体墙,避免了造成车辆损坏和人身伤亡。本发明整体结构紧凑，既可以防止高冲撞力，又可以防止车辆翻越防护栏。
本发明的目的是通过以下技术方案实现的：
一种防撞防越界圆柱万向球体墙，包括防护栏总成以及安装在防护栏总成上的圆柱万向球体机构；所述圆柱万向球体机构包括多个圆柱万向球外壳体6，多个圆柱万向球外壳体6之间依次通过中间支承座8同轴连接，且每个圆柱万向球外壳体6可以单独绕其中轴转动，圆柱万向球体机构两端分别通过弹簧预紧机构与防护栏总成连接；圆柱万向球外壳体6圆周表面上分布镶嵌若干小球体7。
所述圆柱万向球体机构在垂直面上的外表面比防护栏总成外表面更靠近车辆行进方向的左侧或右侧。
进一步地，所述小球体7可相对圆柱万向球外壳体6转动。
进一步地，所述小球体7为橡胶材质或工程塑料。
进一步地，所述弹簧预紧机构包括外壳体支座9、限位连接绳2、导向轮3、回位弹簧10，外壳体支座9固定在防护栏立柱总成上，导向轮3安装在外壳体支座9上，回位弹簧10一端连接在防护栏立柱总成上，回位弹簧10另一端连接限位连接绳2，限位连接绳2另一端连接圆柱万向球体机构外端的中间支承座8上。
进一步地，所述防护栏总成包括防护栏立柱1、固定防撞水泥墩4以及防护栏5，防护栏5固定在防护栏立柱1前端，固定防撞水泥墩4固定在防护栏立柱1后端。
本发明的有益效果是：
当车辆失去控制时，车辆的保险杠或前轮首先撞击到防护栏5或防撞、圆柱万向球外壳体6上，此时车辆的保险杠和防护栏5会吸收车辆的一大部分动能；同时，车辆的车轮与圆柱万向球外壳体6接触，圆柱万向球外壳体6会环绕限位连接绳在360°范围内自身转动。当车辆的前轮先与防撞防越界圆柱万向球体墙接触，车轮带动接触的圆柱万向球外壳体6进行相对转动并和小球体7做万向运 动，此时行进车辆的速度会逐渐降低直至车辆停止。因此，在最大程度下减轻车辆受损的程度，同时可以更好地保护车上人员的人身安全，防止人员伤亡。
由于圆柱万向球外壳体6的特殊结构设计，在壳体的外圆周表面上镶嵌着高强度小球体7，该小球体7可在360°范围内自身转动。当车辆的车轮接触到圆柱万向球外壳体6时，小球体做万向转动并具有防撞击性，减小失控车辆速度和防越界的功能。
同时由于在两个防护栏立柱1之间，多组圆柱万向球外壳体6和小球体7通过限位连接绳2、导向轮3、中间支承座8、外壳体支座9、回位弹簧10固定在两个防护栏立柱水泥墙上，当车辆的前轮先与防撞防越界圆柱万向球体墙接触时，高强度的限位连接绳2通过导向轮3拉伸回位弹簧10，并最大程度减少车辆行进时的动能，使车辆平缓减速，减小撞击；当车辆继续行进时，中间支承座8和固定防撞水泥墩4接触，会进一步阻止车辆前行，最大程度减小车辆损失和人身安全，为驾驶员制动刹车提供宝贵的时间。
