Description

一种防护能力强的金属栏杆 技术领域
本发明涉及金属栏杆领域，特别涉及一种防护能力强的金属栏杆。
背景技术
一般在道路中间会安装护栏进行防护，用来保证交通安全，但是目前的金属护栏都是硬性安装的，如果车辆出现故障而撞向栏杆的时候，由于栏杆的阻挡，会将车辆撞坏，严重的可能会造成人员的伤亡，比较危险，在车辆撞向金属护栏的时候，不能够保证车辆和驾驶人员的安全，这样的护栏虽然可以在道路中间起到防护的功能，但是在车辆撞击的时候不能够对汽车和驾驶员进行防护，不能够及时对车辆进行调整，而且在车辆对栏杆撞击的时候，也不能够及时对对向车道的车辆进行提醒，也不易对对向车道的车辆进行控制，而且在行人通过护栏的时候，如果距离红路灯路口较远，一般会选择跨栏杆，跨栏杆的时候，如果对向车道的车辆没有及时发现，就会比较危险，于是，发明人就针对护栏发生的危险，对护栏进行创造，发明了一种防护能力强的金属栏杆来解决金属护栏的防护问题。
发明内容
本发明的目的是为了解决现有技术的不足，提供了一种防护能力强的金属栏杆。
本发明是通过以下技术方案实现：
一种防护能力强的金属栏杆，包括第一框架、第二框架、第三框 架和对称设置的底板，所述第二框架处在第一框架和第三框架之间，所述第一框架顶面固定安装有第一定位杆，所述第一定位杆顶端固定安装有第一电机，所述第一电机右侧装有第二转轴，所述第二转轴表面右端固定套装有第二链轮，所述第一框架内部均匀套有第一辊筒，所述第一辊筒与第一框架之间装有第一转轴，所述第一转轴表面右端固定套装有第一链轮，所述第一链轮与第二链轮之间连接有第一链条，所述第二框架顶端固定安装有第二定位杆，所述第二定位杆顶端固定安装有第二电机，所述第二电机左侧装有第三转轴，所述第三转轴表面固定套装有第三链轮，所述第二框架内部均匀套有第二辊筒，所述第二辊筒与第二框架之间装有第四转轴，所述第四转轴表面左端固定套装有第四链轮，所述第三链轮与第四链轮之间连接有第二链条，所述第三框架内部对称装有液压缸，所述液压缸顶端装有导轨，所述导轨内部均匀装有滚筒，所述滚筒与导轨之间装有第五转轴，所述底板上表面中部固定安装有支撑块，所述底板上表面背面固定安装有支撑台，所述支撑台上表面固定安装有第二接触片，所述支撑块上方设有顶板，所述顶板与支撑块之间对称装有支撑架，所述支撑架与支撑块之间装有第六转轴，所述顶板后面固定安装有第一接触片，所述顶板上表面固定安装有金属栏杆，所述金属栏杆与支撑块之间对称连接有螺旋弹簧，所述金属栏杆之间均匀连接有连接带，所述金属栏杆两侧面对称套有套管，所述套管内侧面均匀装有插杆，所述套管表面均匀安装有警示灯，所述金属栏杆顶端固定安装有蜂鸣器。
作为优选，所述第一链条与第一链轮和第二链轮啮合配合，第一 转轴与第一框架之间装有轴承。
作为优选，所述第二链条与第三链轮和第四链轮啮合配合，第四转轴与第二框架之间装有轴承。
作为优选，所述导轨为弧形结构。
作为优选，所述插杆为塑料材料制成。
作为优选，所述第一接触片和第二接触片均为铜质材料制成。
与现有技术相比，本发明的有益效果是：
本发明通过第一接触片和第二接触片的控制，可以对蜂鸣器和警示灯进行控制，用来对对向车道的车辆进行提醒，同时对第一电机和第二电机进行控制，就会带动第一辊筒和第二辊筒进行转动，通过第一辊筒和第二辊筒的转动对对向车道的车辆进行平移，就可以实现对对向车道内车辆的移动，为车辆提供足够的空间进行转向，通过对液压缸的控制，可以对导轨进行适当提升，进而通过导轨实现对金属栏杆碰撞车辆的导向，便于使车辆向对向车道进行转向，减少对金属栏杆碰撞而造成的损伤，通过将金属栏杆的底部设置成活动式的，在对金属栏杆撞击的时候会使金属栏杆倾斜，通过设置插杆，起到了阻挡的作用，并且也不会对跨栏杆的行人造成伤害，虽然跨栏杆的行为是不对的，但是还会有人跨越栏杆，在跨越栏杆的时候可以对行人进行保护。本发明通过对第一辊筒和第二辊筒的控制，可以实现对对向车道内车辆的平移，为撞击金属栏杆的车辆提供足够的空间进行转向，通过导轨实现对车辆的转向，保证了车辆和人员的安全。

具体实施方式
下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本发明保护的范围。
请参阅图1-5，本发明提供一种技术方案：
一种防护能力强的金属栏杆，包括第一框架4、第二框架10、第 三框架19和对称设置的底板25，所述第二框架10处在第一框架4和第三框架19之间，所述第一框架4顶面固定安装有第一定位杆8，所述第一定位杆8顶端固定安装有第一电机9，所述第一电机9右侧装有第二转轴7，所述第二转轴7表面右端固定套装有第二链轮6，所述第一框架4内部均匀套有第一辊筒1，所述第一辊筒1与第一框架4之间装有第一转轴2，所述第一转轴2表面右端固定套装有第一链轮3，所述第一链轮3与第二链轮6之间连接有第一链条5，所述第二框架10顶端固定安装有第二定位杆13，所述第二定位杆13顶端固定安装有第二电机12，所述第二电机12左侧装有第三转轴14，所述第三转轴14表面固定套装有第三链轮15，所述第二框架10内部均匀套有第二辊筒11，所述第二辊筒11与第二框架10之间装有第四转轴18，所述第四转轴18表面左端固定套装有第四链轮17，所述第三链轮15与第四链轮17之间连接有第二链条16，所述第三框架19内部对称装有液压缸20，所述液压缸20顶端装有导轨21，所述导轨21内部均匀装有滚筒22，所述滚筒22与导轨21之间装有第五转轴23，所述底板25上表面中部固定安装有支撑块35，所述底板25上表面背面固定安装有支撑台38，所述支撑台38上表面固定安装有第二接触片37，所述支撑块35上方设有顶板29，所述顶板29与支撑块35之间对称装有支撑架28，所述支撑架28与支撑块35之间装有第六转轴27，所述顶板29后面固定安装有第一接触片36，所述顶板29上表面固定安装有金属栏杆33，所述金属栏杆33与支撑块35之间对称连接有螺旋弹簧26，所述金属栏杆33之间均匀连接有连 接带24，所述金属栏杆33两侧面对称套有套管32，所述套管32内侧面均匀装有插杆30，所述套管32表面均匀安装有警示灯31，所述金属栏杆33顶端固定安装有蜂鸣器34。
所述第一链条5与第一链轮3和第二链轮6啮合配合，第一转轴2与第一框架4之间装有轴承。
所述第二链条16与第三链轮15和第四链轮17啮合配合，第四转轴18与第二框架10之间装有轴承。
所述导轨21为弧形结构。
所述插杆30为塑料材料制成。
所述第一接触片36和第二接触片37均为铜质材料制成。
操作步骤：首先对底板25进行安装，就是安装在道路中间安装护栏的位置，使用该护栏来取代现有的护栏，并且在道路上安装多组该装置，每组装置附近都对应装有第一框架4、第二框架10和第三框架19，而底板25安装的时候是倾斜安装的，并且彼此两个底板25是交错的，将第一接触片36接通附近的电源，将第二接触片37接通蜂鸣器34、警示灯31、第一电机9、第二电机12和液压缸20，第一框架4、第二框架10和第三框架19都是平铺在道路上的，平时就相当于减速带，并不影响车辆的行驶，而液压缸20抬升的高度是有限制的，最高为10cm，当车辆失控后会撞向金属栏杆33，此时会使金属栏杆33发生倾斜，就会使第一接触片36和第二接触片37进行接触，此时，就会将蜂鸣器34和警示灯31的开关打开，对对向车道的车辆进行提醒，同时也会将第一电机9和第二电机12的开关打开， 就会带动第一辊筒1和第二辊筒11转动，对对向车道的车辆向外平移，这样在失控车辆通向对向车辆的时候会留出足够的空间，失控的车辆会碾压金属栏杆33到导轨21上，使用导轨21对车辆进行导向，车辆碾压金属栏杆33的时候会对车辆进行减速，并且也减少车辆对金属栏杆33的硬性冲击，通过弧形的导轨21，使车辆在对向车道转向，就防止与对向车道的车辆发生碰撞，保证了车辆行驶的安全。
本具体实施例仅仅是对本发明的解释，并不是对本发明的限制，本领域技术人员在阅读完本说明书后可以根据需要对本实施例做出没有创造性贡献的修改，但只要在本发明的权利要求范围内都受到专利法的保护。
