The invention relates to the technical field of light portal frames, in particular to a light modular fast-assembly portal frame which comprises vertical rod trusses, fixing joints, cross beam trusses and guardrail mechanisms. The bottoms of the vertical rod trusses are connected to the bearing platform through bases and located on the two sides of a railway. Each group of vertical rod trusses comprises a plurality of vertical rod truss sections which are sequentially connected end to end, and the fixed section is fixedly connected to the vertical rod truss section at the top; and two ends of the cross beam truss are respectively connected between the two fixed knots. According to the light modular fast-splicing portal frame and the mounting process thereof, the overall structure of the portal frame uses an aluminum hollow material as a main body, and the truss subjected to oxidation treatment has the characteristics of corrosion resistance and strong acid and alkali resistance in nature, so that long-term maintenance-free can be realized; the device is composed of the vertical rod trusses, the fixing joints, the cross beam trusses, the guardrail mechanisms and the lifting outer sleeves, on one hand, the transportation cost is reduced, and meanwhile the installation cost is reduced.

    本发明涉及轻型龙门架技术领域,具体为一种轻型模块化快拼龙门架,包括:竖杆桁架、固定节、横梁桁架和护栏机构;竖杆桁架设置有两组,且其底部分别通过底座连接在承台上位于铁路的两侧;每组竖杆桁架包括有若干个竖杆桁架节,且依次首尾连接,固定节固定连接在顶部的竖杆桁架节上;横梁桁架的两端分别连接在两个固定节之间。该轻型模块化快拼龙门架及其安装工艺,通过将龙门架整体结构使用铝制中空材质作为主体,经过氧化处理后的桁架可以在自然界中耐腐蚀、耐酸碱性强的特点,可以实现长期免维护,同时进行模块化设计,由竖杆桁架、固定节、横梁桁架、护栏机构、升降外套组成,一方面降低了运输成本,同时安装成本也会降低。
