The invention discloses a wind power hoisting tower crane truss type underframe suitable for all-terrain weak ground pressure and tilt resistance, and belongs to the technical field of hoisting machinery. The underframe comprises a cross-shaped underframe body, four inclined supports, four sets of supports and base distance wide-face supporting legs, wherein the cross-shaped underframe body is supported below the bottom of a tower bottom foundation section, the two ends of the four inclined supports are hinged to the upper portion of the tower bottom foundation section and the top face of thecross-shaped underframe body respectively, four sets of supports are supported below the four farthest ends of the cross-shaped underframe body, and each support is combined with the cross-shaped underframe body through a height adjusting type spherical hinge assembly. The underframe can meet the construction requirements of all-terrain geological foundations with low foundation bearing capacity requirements, tilt resistance and simple foundations, can be compatible with the differences of various geological foundations, and has the advantages of being reasonable in stress, light in structure,light in dead-weight, low in construction cost, convenient to mount and dismount, convenient to transfer and transport and convenient to operate, and the wind power hoisting tower crane truss type underframe is especially suitable for being matched with a wind power hoisting tower crane with short construction period and frequent transition.
本发明公开一种适用于全地形弱地压抗倾斜的风电吊装塔机桁架式底架,属于起重机械技术领域。所述底架包括支撑在塔底基础节底下方的十字形底架,两端分别铰接在塔底基础节上部和十字形底架顶面的四根斜支撑,支撑在十字形底架四个最远端下方的四组支座和基距阔面支腿,每个支座与十字形底架之间均通过高度调节式球铰组件相结合。本发明的底架能够满足地基承载力要求低、抗倾斜、基础简单的全地形地质基础的施工要求,能够兼容多种地质基础的差异性,具有受力合理、结构轻巧、自重轻、造价低、便于安装和拆卸、方便转场和运输、操作方便的优点,尤其适合与工期短、转场频繁的风电吊装塔机配用。
