新型高速铁路专用桥梁检测车的设计方案

Design scheme of bridge-inspection vehicle applies for new high-speed railway bridge

为了解决新型高速铁路桥梁取消人行便道、受"天窗"时间限制等传统桥梁检测维护设备不能达到检测要求的问题,提出了一种新型高速铁路专用桥梁检测车的机械设计方案。该检测车设计采用门式梁固联、导向梁和驱动梁交替行走结构形式;利用图像采集技术实施对高铁桥梁下表面及桥墩的检测;可在不影响列车正常通行的情况下,实现自动过墩。最后,用Solidworks完成了三维建模及动画仿真,并进行了虚拟样机试验。研究结果表明,该设计方案是可行的,为更多高速铁路桥梁检测维护设备研发提供了借鉴和参考。

In order to solve the problems of new high-speed railway bridge cancel human pavement,the skylight time limit and other characteristics that traditional bridge test equipment maintenance can＇t reach the detection requirements, a mechanical design plan of new high-speed railway bridge-detection vehicle was investigated. This bridge-detection vehicle uses the structure of fixed gate-type girder,its guiding girder and drive girder walk alternately. This vehicle can detect the onderkant of the bridge and bridge piers with image acquisition technology and can pass the bridge pier automatically without affect the normal train traffic. And its 319 modeling and simulation animation was completed by Solidworks, the virtual prototype was tested. The experimental results show that this design scheme is feasible. This plan will provide reference to more testing and maintenance of railway bridge equipment research and development.
