The invention provides an automatic leveling system for a working platform. One end of an arm frame is rotationally connected with the upper part of a central column; the other end of the arm frame is rotationally connected with the adjacent end of the working platform; one end of a pitching oil cylinder is rotationally connected with the lower part of the central column, and the other end of the pitching oil cylinder is rotationally connected with the arm frame; one end of a follow-up oil cylinder is rotationally connected with the central column, and the connecting position of the follow-up oil cylinder and the central column is located between the connecting position of the central column and the arm frame and the connecting position of the central column and the pitching oil cylinder; the other end of the follow-up oil cylinder is rotationally connected with the arm frame; one end of a leveling oil cylinder is rotationally connected with the other end of the arm frame; and the other end of the leveling oil cylinder is rotationally connected with the working platform. The automatic leveling system has the advantages that the working platform can reach any height or any depth through pitching of the arm frame, high lifting or downward stretching of people or objects is achieved, and the angle of the working platform is kept unchanged in the action process.

    本发明提供一种作业平台自动调平系统,臂架的一端与中心柱的上部可旋转连接;臂架的另一端与作业平台相邻的一端可旋转连接;俯仰油缸的一端与中心柱的下部可旋转连接,俯仰油缸的另一端与臂架可旋转连接;随动油缸的一端与中心柱可旋转连接,且两者的连接位置位于中心柱与臂架的连接位置和中心柱与俯仰油缸的连接位置之间;随动油缸的另一端与臂架可旋转连接;调平油缸的一端与臂架另一端可旋转连接;调平油缸的另一端与作业平台可旋转连接。其优点在于通过臂架俯仰,使作业平台到达任意高度或任意深度,实现人或物的高举或下探,且在动作过程中,作业平台的角度保持不变。
