The cantilever crane structure comprises a built-in oil cylinder with the two ends fixed to a first arm and a second arm respectively, the built-in oil cylinder drives the second arm to stretch out and draw back, the second arm is provided with a connecting wheel penetrating shaft, an extending inhaul cable winds around the connecting wheel penetrating shaft, the two ends of the extending inhaul cable are fixed to the first arm and a third arm respectively, and the action that the third arm is pulled to stretch out is achieved; and the retraction inhaul cable bypasses the extension inhaul cable connecting wheel, so that the retraction action of the three arms is realized. The device is simple and convenient to operate, and can be quickly disassembled, assembled and overhauled to maintain, detect and repair the interior. 本发明公开了一种便于拆装的臂架结构，包括两端分别固定在一臂与二臂的内置油缸，内置油缸驱动二臂进行伸缩动作，二臂设有连接轮穿轴，伸出拉索绕过连接轮穿轴，两端分别固定在一臂与三臂，实现拉动三臂伸出动作；缩回拉索绕过伸出拉索连接轮，实现三臂的缩回动作。本发明操作简便，可进行快速拆装检修，对内部进行保养、检测和维修等工作。
