The invention relates to the technical field of power transmission line construction, in particular to a movable self-folding and self-lifting derrick which comprises a crawler-type vehicle body and a derrick body. Wherein the derrick is arranged on the crawler-type vehicle body in a horizontal state after being folded, and the crawler-type vehicle body is used for transporting the derrick to a working place; the derrick comprises a folding driving mechanism, an inverted frame, a heightening assembly, a lifting driving device, a rotating mechanism, an overturning driving mechanism, a mast section, a main arm, an unfolding driving mechanism and other structural parts, and the structural parts are assembled together to form the novel derrick. The power transmission line construction trolley is simple in structure and small in occupied space, is provided with the crawler-type trolley body, is more convenient to transport, can be unfolded when being used again, is simple and convenient to operate, saves time and labor, greatly improves the power transmission line construction efficiency, saves human input, and is of great significance in power transmission line construction.

    本申请涉及输电线路施工技术领域,尤其是涉及一种移动式自折叠自升降抱杆,包括:履带式车体以及抱杆;其中,抱杆折叠后呈卧式状态设置在履带式车体上,且履带式车体用于将抱杆运输到工作地;抱杆包括折叠驱动机构、倒装架、加高组件、升降驱动装置、回转机构、翻转驱动机构、桅杆节、主臂以及展开驱动机构等结构件,上述结构件组装在一起,形成了一种新型的抱杆,本申请提供的移动式自折叠自升降抱杆在使用结束后可折叠收纳,占用空间小,而且配设有履带式车体,更加便于运输,再次使用时又可展开,操作简单、方便,省时省力,极大地提升了输电线路施工的效率,并且节省了人力投入,这在输电线路施工中是具有重要意义的。
