The embodiment of the invention provides a portal frame. The portal frame comprises a plurality of supporting leg mechanisms and a main beam mechanism; the supporting leg mechanisms comprises a plurality of supporting leg splicing units which are used for supporting the main beam mechanism; and the main beam mechanism is constructed to bear an object to be hoisted. Therefore, the dependence on special equipment in the installation process is reduced, and the cost consumed in the transportation and installation process is saved. Meanwhile, according to the requirements of different users for different spans and lifting heights of portal frame products, different numbers of supporting leg splicing units are selected for splicing, and portal frames with different spans and lifting heights can be spliced, so that the requirements of different users are met, the supporting leg mechanisms does not need to be redesigned and produced, the overall design and production difficulty of the portal frame is reduced, large-scale assembly line work can be formed in the production process of a factory, and therefore the production efficiency of the portal frame is improved.
本申请一实施例提供的一种龙门架,多个支腿机构,包括多个支腿拼接单元,用于支持主梁机构;以及所述主梁机构,构造为承载待吊运的物体。以此减少安装过程中对特种设备的依赖,从而节省在运输和安装过程中所消耗的成本;同时根据不同用户对龙门架产品的不同跨度和起升高度的要求,选择不同数量支腿拼接单元拼接,即可拼装形成不同跨度和起升高度的龙门架,从而满足不同用户的需求,因此不需要重新对支腿机构进行重新设计和生产,降低了龙门架整体的设计和生产难度,有利于工厂在生产过程中形成规模化的流水线作业,从而提高龙门架的生产效率。
