The invention provides a working arm capable of improving the working range and stroke and an engineering mechanical vehicle. The working arm comprises a base, a first connecting arm, a telescopic arm mechanism, an executing mechanism and a pitching angle adjusting mechanism, one end of the first connecting arm is hinged to the base, and the other end of the first connecting arm is hinged to one end of the telescopic arm mechanism; the other end of the telescopic arm mechanism is connected with an executing mechanism, the pitching angle adjusting mechanism is hinged to the base, the first connecting arm and the telescopic arm mechanism so as to provide a pitching angle for the whole working arm, and then the working range and stroke of the working arm are provided; and the working arms are arranged on the vehicle body to form different types of engineering machinery vehicles. The structure is simple, the pitching angle of the working arm can be increased, and therefore the working range and stroke are increased.

    本发明提供一种提高工作范围、行程的工作臂以及工程机械车,该工作臂包括基座、第一连接臂、伸缩臂机构、执行机构、以及俯仰角度调节机构,第一连接臂的一端与基座铰接、另一端与伸缩臂机构的一端铰接,伸缩臂机构的另一端连接设有执行机构,俯仰角度调节机构分别与基座、第一连接臂、以及伸缩臂机构铰接,以为整个工作臂提供俯仰角度,进而提供工作臂的工作范围和行程;工作臂设置在车体上形成不同类型的工程机械车。本发明结构简单,可以增大工作臂的俯仰角度,从而增大工作范围和行程。
