The invention relates to the field of railway vehicles, and provides a vehicle roof structure, a vehicle body and a railway vehicle. The two sides, extending in the longitudinal direction of the vehicle body, of the top plate are connected with the camber beams in a welded mode; the mounting beam is arranged on the side, opposite to the bent beam, of the top plate and suitable for being connected with roof equipment. According to the mounting beam, mounting bases of all devices are integrated in a unified mode, the number of welding bases is reduced, meanwhile, welding defects caused by large welding amount and large deformation are avoided, the overall structure quality and stability of a car roof and the bearing capacity of the car roof are improved, the utilization efficiency of the car roof space is improved, the mounting process of the car roof devices is simplified, and the cost is reduced. And the installation time and cost are reduced.
本发明涉及轨道车辆领域,提供一种车顶结构、车体及轨道车辆,车顶结构包括弯梁、顶板和安装梁;顶板位于弯梁背向车体内部的一侧,且顶板沿车体纵向方向延伸的两侧与弯梁焊接连接;安装梁设置于顶板背向弯梁的一侧,安装梁适于与车顶设备连接。安装梁将各个设备的安装座统一集成,减少了焊座数量,同时避免了因焊接量大和形变大而产生的焊接缺陷,不仅提高了车顶的整体结构质量和稳定性和车顶的承重能力,还提高了车顶空间的利用效率,简化了车顶设备的安装过程,减少了安装时间和成本。
