The invention relates to a double-layer forklift based on double four-link mechanisms. The double-layer forklift comprises an underframe, a linear driving device mounted on the underframe, a lower-layer lifting swing frame, and an upper-layer lifting swing frame. Two pairs of walking wheels which are symmetrical left and right are mounted on the two sides of the underframe, two vertical symmetrical stand columns are fixed to the rear end of the underframe, and vertical plates which are symmetrical left and right are fixed to the outer sides of the stand columns. The lower end of a fixed rod ofthe linear driving device is hinged to a first connecting base fixed to the underframe. The upper-layer lifting swing frame is mounted on the vertical plates and driven by the stretching and retracting of the linear driving device to swing up and down so as to complete the lifting action, the linear driving device can swing by a certain angle in the stretching and retracting process, and in the swinging process, the lower-layer lifting swing frame is driven to swing so as to complete the lifting action at the same time. One power device drives the two lifting swing frames to work, the completed work is doubled through one-time operation, the working efficiency is high, use is convenient, and operation is easy.

    本发明涉及一种基于双四连杆机构的双层叉车,包括底架、安装在底架上的直线驱动装置、下层举升摆架、上层举升摆架,底架的两侧安装有两对左右对称的行走轮,在底架的后端固定有两根竖直对称的立柱,每根立柱的外侧均固定有左右对称的立板,直线驱动装置固定杆的下端铰接在与底架固定的第一连接座上,上层举升摆架安装在立板上,通过直线驱动装置的伸缩驱动其上下摆动,进而完成举升动作,直线驱动装置在伸缩的过程中同时会产生一定角度的摆动,在摆动的过程中带动下层举升摆架摆动,使其同时完成举升动作,一个动力装置带动两套举升摆架工作,单次操作完成两倍的工作量,工作效率高,使用方便,操作简单。
