The invention discloses a tower body self-supporting device, a tower crane and a tower body self-supporting method.The tower body self-supporting device comprises a supporting arm, a pull rod tensioning mechanism and a force measurement control assembly, the supporting arm is arranged on a tower body, the pull rod tensioning mechanism comprises a telescopic driving part and a pull rod assembly, the telescopic driving part is arranged on a tower body base, the driving end of the telescopic driving part is arranged upwards, and the pull rod assembly is arranged on the tower body base; the two ends of the pull rod assembly are connected with the driving end of the telescopic driving piece and the supporting arm in a one-to-one correspondence mode, and the force measurement control assembly is used for detecting the tensioning force of the pull rod tensioning mechanism and generating an overrun instruction under the condition that detection data exceed the safety threshold value range. The tension force of the pull rod tensioning mechanism is detected, and the overrun instruction can be generated under the condition that the detection data exceed the safety threshold range, so that corresponding processing is prompted, the phenomenon that the stress of the pull rod assembly exceeds the standard is avoided, and the working safety of the whole tower crane is improved.

    本发明公开了一种塔身自支撑装置、塔式起重机及塔身自支撑方法,塔身自支撑装置包括支撑臂、拉杆张紧机构和测力控制组件,支撑臂设于塔身上,拉杆张紧机构包括伸缩驱动件和拉杆组件,伸缩驱动件设于塔身底座上且驱动端朝上设置,拉杆组件的两端分别与伸缩驱动件的驱动端和支撑臂一一对应连接,测力控制组件用于对拉杆张紧机构的张紧拉力进行检测并在检测数据超出安全阈值范围的情况下生成超限指令,在塔机工作过程中可通过增设的测力控制组件,对拉杆张紧机构的张紧拉力进行检测,并能够在检测数据超出安全阈值范围的情况下生成超限指令,以便于提示进行相应处理,避免拉杆组件出现应力超标的现象,提升整个塔机工作的安全性。
