Abstract

一种公路跨线桥梁桥墩防护装置，包括桥墩本体，所述桥墩本体的底端横向设有方钢，所述方钢的表面长度方向设有滑槽，所述滑槽内镶嵌有滑块，所述滑块的顶端设有纵向孔，所述纵向孔内设有立轴，所述立轴上焊接有防撞板，还包括套管，所述套管内设有碟簧，所述碟簧的两端设有支撑杆，所述支撑杆的一端与桥墩本体固定连接，所述支撑杆的另一端通过转轴与防撞板铰接。本发明通过防撞板避免车辆直接撞到桥墩本体上，通过立轴与转轴的配合使防撞板斜向设置后，车辆顺着防撞板的斜向滑出，避免车内的人员严重受伤。

Description

一种公路跨线桥梁桥墩防护装置
技术领域
本发明涉及一种公路跨线桥梁桥墩防护装置。
背景技术
由于跨线桥梁桥墩立于公路中间或是两侧，极易造成车辆撞击桥墩的事故，产生严重的经济损失和人员伤亡，同时也严重影响桥梁的安全性。
发明内容
本发明的目的是针对上述的不足，提供一种公路跨线桥梁桥墩防护装置。
所述目的是通过如下方案实现的：
一种公路跨线桥梁桥墩防护装置，包括桥墩本体，所述桥墩本体的底端横向设有方钢，所述方钢的表面长度方向设有滑槽，所述滑槽内镶嵌有滑块，所述滑块的顶端设有纵向孔，所述纵向孔内设有立轴，所述立轴上焊接有防撞板，还包括套管，所述套管内设有碟簧，所述碟簧的两端设有支撑杆，所述支撑杆的一端与桥墩本体固定连接，所述支撑杆的另一端通过转轴与防撞板铰接，所述支撑杆两侧设有支臂，所述支臂设置在桥墩本体上。
本发明具有以下优点：本发明通过防撞板避免车辆直接撞到桥墩本体上，通过立轴与转轴的配合使防撞板斜向设置后，车辆顺着防撞板的斜向滑出，避免车内的人员严重受伤。
附图说明
图1是本发明的结构示意图。
其中，1-桥墩本体，2-方钢，3-滑槽，4-滑块，5-纵向孔，6-立轴，7-防撞板，8-套管，9-碟簧，10-支撑杆，11-转轴，12-支臂。
具体实施方式
下面结合附图详细阐述本发明优选的实施方式。
一种公路跨线桥梁桥墩防护装置，包括桥墩本体1，所述桥墩本体1的底端横向设有方钢2，所述方钢2的表面长度方向设有滑槽3，所述滑槽3内镶嵌有滑块4，所述滑块4的顶端设有纵向孔5，所述纵向孔5内设有立轴6，所述立轴6上焊接有防撞板7，还包括套管8，所述套管8内设有碟簧9，所述碟簧9的两端设有支撑杆10，所述支撑杆10的一端与桥墩本体1固定连接，所述支撑杆10的另一端通过转轴11与防撞板7铰接。所述支撑杆10两侧的桥墩本体1上设有支臂12。
方钢2的端头与桥墩本体1固定连接，防撞板7为不锈钢板，支臂12防止防撞板7斜向设置时与桥墩本体1贴合，当车辆失控撞击到防撞板7上时，滑块4在滑槽3内向后滑动，防撞板7推动支撑杆10、碟簧9在套管8内回缩，通过碟簧9减小撞击力，当滑块4滑到滑槽3内的端头与滑槽3内壁撞击时，通过车辆的撞击力防撞板7带动立轴6在纵向孔5内转动，通过转轴11的配合使防撞板7斜向设置，同时车辆顺着防撞板7斜向滑出，完全将撞击力化解，避免撞到桥墩本体1上。
本实施方式只是对本专利的示范性说明而并不限定它的保护范围，本领域人员还可以对其进行局部改变，只要没有超出本专利的精神实质，都视为对本专利的等同替换，都在本专利的保护范围。
