The invention provides a ceiling hoisting structure for a railway vehicle, which comprises small hoisting parts, sliding chutes and longitudinal beams connected to two sides of a ceiling camber beam, the longitudinal beams are connected with the sliding chutes, the small hoisting parts are connected to the sliding chutes on two sides through fasteners, and parts in the vehicle are connected with the small hoisting parts on two sides through fasteners. And the connection between the vehicle interior part and the ceiling structure is realized. According to the invention, the height positioning requirement of equipment can be better met, the use of an adjusting pad is reduced, and the installation of the equipment is more facilitated; and the use of small welding parts is reduced, the adjustment of the equipment in the length direction of the vehicle is facilitated by adopting the small welding parts, and the error-tolerant rate is improved.
本发明提供一种轨道车辆用顶棚吊装结构,包括:吊装小件、滑槽以及连接在顶棚弯梁两侧的纵梁,所述纵梁上连接滑槽,所述吊装小件通过紧固件连接在两侧滑槽上,车内部件通过紧固件与两侧吊装小件连接,实现车内部件与顶棚结构的连接。本发明可保证设备更好的满足高度定位要求,且减少了调整垫的使用,更利于设备的安装;减少了焊接小件的使用,采用把接小件更有利于设备在车长方向上的调整,提高容错率。
