The handrail structure comprises a stand column profile and a handrail rod, the stand column profile is integrally a right-angle plate, buckling structures facilitating connection are arranged on the two sides of the stand column profile, and the buckling structures are arranged at the corners of end plates at the connecting channel of adjacent carriages and the protruding side of the stand column profile. Three sections of arc-shaped grooves are coaxially formed along the right-angle side of the stand column profile, the diameter of the two sections of arc-shaped grooves located at the two ends is matched with the diameter of the handrail rod, the diameter of the section of arc-shaped groove located in the middle is located between the diameter of the handrail and the shortest side length of the stand column profile, and the two ends of the handrail rod are embedded and fixed into the two sections of arc-shaped grooves located at the two ends. The corners of the end plates at the connecting channels of the adjacent carriages are connected through the stand column sectional materials, and the handrail rods are installed on the stand column sectional materials, so that installation of the handrail structure is achieved, and the problem that in the prior art, no protective handrail exists at the connecting channels of the adjacent carriages, and potential safety hazards exist is solved.
本发明公开了一种轨道车辆通道处扶手结构及加工方法,包括立柱型材和扶手杆,立柱型材整体为直角板材,立柱型材两边设置有便于连接的扣合结构,且其设置在相邻车厢连接通道处的端板拐角处,立柱型材的突出侧,沿立柱型材的直角边同轴设置有三段弧形槽,处于两端的两段弧形槽的直径与扶手杆的直径相匹配,处于中间的一段弧形槽的直径处于扶手的直径和立柱型材的最短边长之间,扶手杆的两端嵌入并固定在处于两端的两段弧形槽内;本申请在相邻车厢的连接通道处端板的拐角处通过立柱型材进行连接,并在立柱型材上安装扶手杆,从而实现扶手结构的安装,解决现有技术中相邻车厢连接的通道处没有可防护的扶手,存在安全隐患的问题。
