The invention provides a jacking sleeve frame for a tower crane with capability of increasing or decreasing sections on the top and the tower crane, and relates to the field of tower cranes. The jacking sleeve frame for the tower crane with the capability of increasing or decreasing the sections on the top is used for moving along a tower body composed of a plurality of standard sections which are connected in sequence, a supporting frame and a lower supporting frame are arranged up and down and are arranged on the tower body in a sleeving mode, and the two ends of a hydraulic oil cylinder are connected with an upper supporting frame and the lower supporting frame correspondingly; and a jacking fixing assembly is used for driving the upper supporting frame to be disconnected from the correspondingly-connected standard section and then ascend to be connected with the standard section above when an oil cylinder rod of the hydraulic oil cylinder extends out, and driving the lower supporting frame to be disconnected from the correspondingly-connected standard section and then ascend to be connected with the standard section above when the oil cylinder rod of the hydraulic oil cylinder retracts. The jacking sleeve frame for the tower crane with the capability of increasing or decreasing the sections on the top according to an embodiment can stably ascend and descend along the tower body and has the advantages that the structure is stable, and the tower body is fixed firmly.
一种用于顶部加减节塔机的顶升套架及塔机,涉及塔式起重机领域。该用于顶部加减节塔机的顶升套架用于沿多个依次连接的标准节组成的塔身移动,支撑框架和下支撑框架上下布置且分别套设于塔身上,液压油缸的两端分别与上支撑框架和下支撑框架连接;顶升固定组件用于在液压油缸的油缸杆伸出时驱动上支撑框架与对应连接的标准节解除连接后上升至与上方的一个标准节连接,以及在液压油缸的油缸杆收回时,驱动下支撑框架与对应连接的标准节解除连接后上升至与上方的一个标准节连接。本实施例提供的用于顶部加减节塔机的顶升套架能够稳定的沿塔身升降,具有结构稳定和与塔身固定牢固的优点。
