The invention relates to the technical field of railway vehicles and particularly relates to a folding shed windshield structure of a railway vehicle. A welding column is fixedly connected with a transition plate frame, a fixing bolt is in threaded connection with the transition plate frame, a butt joint plate is detachably connected with the transition plate frame, a clamping piece is fixedly connected with the butt joint plate, a windshield is fixedly connected with the butt joint plate, when installing and connecting the windshield, the transition plate frame is firstly welded and fixed with a carriage through welding columns, then the windshield is connected and fixed with the butt joint plate, a protrusion of the butt joint plate is inserted into a mounting groove of the transition plate frame, the protrusion is clamped with the mounting groove, clamping pieces on the two sides of the protrusion are inserted into clamping grooves in the two sides of the mounting groove respectively, the transition plate frame and the butt joint plate are firmly clamped and fixed, and the fixing bolt is rotated to be inserted into the fixing hole in the butt joint plate. The connecting and fixing effect of the transition plate frame and the butt joint plate is enhanced, and a problem that flash seams are prone to occurring due to the fact that an existing folding shed windshield is not enough in locking force is solved.
本发明涉及轨道车辆技术领域,具体涉及一种轨道车辆的折棚风挡结构;焊接柱与过度板框固定连接,固定螺栓与过度板框螺纹连接,对接板与过度板框拆卸连接,卡接片与对接板固定连接,风挡与对接板固定连接,安装连接风挡时,先将过度板框与车厢通过焊接柱焊接固定,再将风挡与对接板连接固定,将对接板的凸起插入过度板框的安装槽内,凸起与安装槽卡合,凸起两侧的卡接片分别插入安装槽两侧的卡槽中,将过度板框和对接板牢牢地卡合固定,旋转固定螺栓使固定螺栓插入对接板上的固定孔内,加强过度板框和对接板的连接固定效果,解决现有折棚风挡,锁紧力不够容易出现闪缝的问题。
