The portal frame comprises an outer portal frame body vertically arranged on a frame, a middle portal frame body embedded in the outer portal frame body in a liftable mode and an inner portal frame body embedded in the middle portal frame body in a liftable mode, the outer portal frame body and the middle portal frame body are each of a rectangular frame box structure, and reinforcing structures are arranged on the outer portal frame body and the middle portal frame body in the transverse direction and the longitudinal direction. Therefore, the strength and rigidity of the outer door frame and the middle door frame in the transverse direction and the longitudinal direction are improved. The narrow door frame design is adopted, meanwhile, the outer door frame adopts the ladder-shaped cross beam structure, the view boundary of a driver is approximately overlapped with the two sides of the ladder-shaped cross beam, blocking of the corners of the two sides of the cross beam is reduced, and the view range of the left side and the right side of the door frame is effectively widened; and meanwhile, the upper and lower cross beams of the outer gantry and the middle gantry are connected through wrapping plates to form an integral frame box type structure, the structure is integrated, the longitudinal and transverse rigidity of the gantry is enhanced, and the stability of the gantry during stacking at a rising position is improved.

    本发明公开了一种门架,包括垂直设置在车架上的外门架、可升降的嵌设在外门架内的中门架、可升降的嵌设在中门架内的内门架,所述外门架、中门架均为矩形框架箱体结构,且外门架、中门架在横向和纵向方向上均设置有加强结构,以增加外门架、中门架在横向和纵向上的强度和刚性。本发明采用窄体门架设计,同时外门架应用“梯”字型横梁结构,使驾驶员的视野边界与“梯”字型横梁两边近似重合,减小横梁两侧边角遮挡,有效提升门架左右两侧视野范围;同时外门架和中门架上下各个横梁之间用包板连接,形成一个整体框架箱型结构,结构一体化,增强门架纵向和横向刚性,提高升高位堆垛时门架稳定性。
