The invention discloses a tractor rear suspension double-layer arm lifting platform device which comprises an operating system and a lifting mechanism. The tractor rear suspension double-layer arm lifting platform device is characterized in that a platform and a platform stand column fixed to the platform are sequentially hinged to a second-layer arm, a first-layer arm and a main machine stand column, and then are connected and fixed to the rear portion of a tractor through a three-point suspension upper connecting rod and a three-point suspension lower connecting rod; the second-layer arm and the first-layer arm are respectively pushed and lifted by a second-layer arm oil cylinder and a first-layer arm oil cylinder; and a balance pull rod a and a balance pull rod b are arranged to control the platform plane to be parallel to the ground all the time in the lifting process. The design of the lifting mechanism is simple, the tractor provides hydraulic power to complete lifting and the walking process, the cost is low, and the device is safe and reliable.

    一种拖拉机后悬挂双层臂升降平台装置,包括操作系统和升降机构,其特征在于,站台及与之固定一起的站台立柱通过依次铰接二层臂、一层臂、主机立柱,在通过三点悬挂上连接杆、三点悬挂下连接杆连接固定于拖拉机后面;二层臂、一层臂分别由二层臂油缸、一层臂油缸推动举升;设置平衡拉杆a、平衡拉杆b控制升降过程中站台平面始终与地面保持平行。本发明升降机构的设计做到了应简尽简,靠拖拉机提供液压动力完成升降及行走过程成本低,安全可靠。
