The invention discloses a novel folding type auxiliary arm structure and an automobile crane. The auxiliary arm structure comprises a main body structure I and a main body structure II, the main body structure I is connected with the main body structure II through a pin shaft, and the main body structure II can be folded to the bottom of the main body structure I. During folding, the front end of the main body structure II is fixedly connected with the main body structure I through a fixing structure. According to the above structure, the working range of an auxiliary arm can be expanded, and functions are improved. In addition, an auxiliary butt joint structure is further arranged on the auxiliary arm structure, and butt joint of the main body structure I and the main body structure II is facilitated. Angles of a middle connecting body and the main body structure I can be adjusted through a variable-angle structure.
本发明公开了一种新型折叠式副臂结构及汽车起重机,副臂结构包括主体结构一和主体结构二,主体结构一与主体结构二通过销轴连接,主体结构二可以折叠到主体结构一底部,折叠时,主体结构二的前端与主体结构一通过固定结构连接固定。上述结构可以副臂工作范围得到扩展,功能得到提高。另外,在副臂结构上还设置有辅助对接结构,方便主体结构一和主体结构二的对接。中间连接体和主体结构一可通过变角结构进行角度调整。
