The invention relates to the technical field of drilling pile construction tools, in particular to a crawler-type foldable portal frame. The portal frame comprises a portal frame body, and the portal frame body comprises a mounting frame used for lifting the reinforcement cage and a walking device used for consigning the mounting frame. The walking device comprises a supporting plate, crawler wheels are arranged below the supporting plate, and a diesel engine used for driving the crawler wheels to rotate is arranged above the supporting plate. A first hinge block is arranged at one end of the supporting plate, and the first hinge block is hinged to the mounting frame; a winch is further arranged above the supporting plate and used for pulling the mounting frame to rotate along the hinged position. The overall length of the portal can be reduced, and the portal can be conveniently transferred in a small construction site; compared with the prior art, the portal frame can be transferred without the help of a trailer, can be folded to reduce the body length and can be transferred in a construction site, and the construction efficiency of constructors is improved.

    本发明涉及钻孔桩施工工具技术领域,具体地说,涉及一种履带式可折叠门架。其包括门架主体,门架主体包括用于吊放钢筋笼的安装架,以及用于托运安装架的行走装置;行走装置包括支撑板,支撑板下方设有履带轮,支撑板上方设有用于驱动履带轮转动的柴油机;支撑板一端设有第一铰接块,第一铰接块与安装架之间铰接;支撑板上方还设有卷扬机,卷扬机用于拉动安装架沿铰接处转动。能够使门架整体长度减小,便于在较小的施工场地转运;与现有技术相比,该门架无需借助拖车转运,并且可折叠减小体长,并于在施工场地转运,提升了施工人员的施工效率。
