The invention provides a half cab framework and a railway vehicle. The half-body cab framework comprises a front end cross beam, a left longitudinal beam and a right longitudinal beam, the two ends of the front end cross beam are fixed to the left longitudinal beam and the right longitudinal beam through oblique beams respectively to form a half-body cab middle frame, and the half-body cab middle frame is welded and fixed to a vehicle body chassis through a plurality of stand columns. The semi-body cab framework is formed by installing and welding aluminum profiles and is connected with the underframe through welding, no vehicle body framework is arranged above the semi-body cab framework, and the influence of the framework on the mask shape is greatly reduced. The single-rail welding device has the advantages of being simple in structure, small in welding workload, short in production period, low in cost and the like.
本发明提供的半体司机室骨架及轨道车辆。半体司机室骨架包括:前端横梁、左纵梁和右纵梁,所述前端横梁两端分别通过斜梁与所述左纵梁和右纵梁固定形成半体司机室中部框架,所述半体司机室中部框架通过若干立柱焊接固定于车体底架上。本发明半体司机室骨架由铝型材组焊,通过焊接与底架连接,上方无车体骨架,大大降低骨架对面罩造型的影响。在单轨和同时具有结构简单、焊接工作量小、生产周期短、成本低等特点。
