The invention discloses an integral self-lifting device for upper equipment of a tower crane. The device comprises a tower body that is fixed on the ground through fixing anchors and composed of a plurality of standard sections, wherein the outer side of the tower body is sleeved with a jacking sleeve frame, and the upper part is connected to the lower part of a rotary assembly through a hinge pin; the upper part of the rotary assembly is connected to a tower head through a hinge pin; the outer side of the tower head is sleeved with an enveloping tower head that is connected to the tower headthrough a hinge pin, both sides of the enveloping tower head are respectively connected to a balance arm and an arm frame assembly through hinge pins, and the lower end is placed on the upper part ofthe jacking sleeve frame. The integral self-lifting device for the upper equipment of the tower crane can prevent the superstructure of the tower crane from instability and tilting when the tower crane is in strong wind, bad weather and other conditions during the construction, and achieve the integral self-lifting requirements of the upper part of the tower crane. The integral self-lifting deviceis simple in structure, reasonable in resign and humanized in the integral structure, and greatly improves the safety of the tower crane.
本发明公开了一种塔式起重机上部设备整体自升降装置,包括通过固定地脚固定在地面上、由多个标准节构的塔身,该塔身外侧套装有顶升套架,上部通过销轴与回转总成的下部连接;回转总成的上部通过销轴与塔头连接;在塔头外侧套装有通过销轴与其连接的外包塔头,该外包塔头两侧分别通过销轴连接平衡臂及臂架总成,下端置于顶升套架上部。本发明能够满足塔式起重机在施工中遇大风及恶劣天气等情况下,避免塔式起重机上部结构失稳倾翻,实现塔机上部整体自升降要求。本发明结构简单、设计合理,整体结构人性化,大幅度增加了塔式起重机的安全性。
