The invention discloses a power assisting carrying mechanical hand. A first mechanical arm, a second mechanical arm, a first telescopic drive piece, a second telescopic drive piece, an installing base, a rotation drive piece and a winding wheel around which a drive rope is wound are included. One end of the first mechanical arm is provided with a hoisting mechanism, and the other end is hinged toone end of the second mechanical arm. The other end of the second mechanical arm is hinged to the installing base, the installing base is arranged on the rotation drive piece, one end of the first telescopic drive piece and one end of the second telescopic drive piece are connected with the installing base, and the other end of the first telescopic drive piece drives the second mechanical arm to swing up and down. The winding wheel is pivoted to the installing base. The other end of the second mechanical arm drives the winding wheel to rotate, and the drive rope is in transmission connection with the first mechanical arm. The first mechanical arm of the power assisting carrying mechanical hand is driven by the winding wheel around which the drive rope is wound, accordingly, the drive pieceis arranged on the installing base, the additional weight exerted on the first mechanical arm and the second mechanical arm which serve as cantilever structures is avoided, and meanwhile the swingingangle of the first mechanical arm is enlarged.
本发明公开了一种助力搬运机械手,包括第一机械臂、第二机械臂、第一伸缩驱动件、第二伸缩驱动件、安装座、旋转驱动件和卷绕有驱动绳的卷轮,第一机械臂的一端设置有起重机构,另一端与第二机械臂的一端铰接,第二机械臂的另一端与安装座铰接,安装座设置在旋转驱动件上,第一伸缩驱动件和第二伸缩驱动件的一端均与安装座连接,第一伸缩驱动件的另一端驱动第二机械臂上下摆动,卷轮与安装座枢接,第二机械臂的另一端驱动卷轮转动,驱动绳与第一机械臂传动连接。本发明的第一机械臂采用卷绕有驱动绳的卷轮驱动,从而,将驱动件设置到安装座上,避免避免第一机械臂和第二机械臂作为悬臂结构所承受的额外重量,同时,扩大了第一机械臂的摆动角度。
