The invention discloses a lifting machine oil cylinder system which is characterized in that one end of a main oil cylinder is communicated with a power component through a main oil inlet pipe, the other end of the main oil cylinder is communicated with one end of an auxiliary oil cylinder through a main oil return pipe and an auxiliary oil inlet pipe, and the other end of the auxiliary oil cylinder is communicated with the power component through an auxiliary oil return pipe; the main oil return pipe is arranged at the other end of the main oil cylinder and communicated with the auxiliary oil inlet pipe, the auxiliary oil inlet pipe is arranged at one end of the auxiliary oil cylinder, a first step is arranged at the other end of the main oil cylinder, and the diameter of an inner cavity at one end of the main oil cylinder is smaller than that of an inner cavity at the other end of the main oil cylinder. The other end of the auxiliary oil cylinder is provided with a second step, and the diameter of an inner cavity of one end of the auxiliary oil cylinder is smaller than that of an inner cavity of the other end of the auxiliary oil cylinder, so that oil at one end of the auxiliary oil cylinder can enter the other end of the auxiliary oil cylinder. The system can automatically exhaust and supplement oil, is convenient to operate and safer, and avoids waste and pollution of oil during exhaust.

    本发明公开一种举升机油缸系统,包括:主油缸的一端通过主进油管与动力部件相连通,主油缸的另一端通过主回油管、副进油管与副油缸的一端相连通,副油缸的另一端通过副回油管与动力部件相连通,其中主回油管设置在主油缸的另一端,主回油管与副进油管相连通,副进油管设置在副油缸的一端,主油缸的另一端设置有第一台阶,主油缸的一端的内腔直径小于主油缸的另一端的内腔直径,以使得主油缸的一端的油能够进入主油缸的另一端,副油缸的另一端设置有第二台阶,副油缸的一端的内腔直径小于副油缸的另一端的内腔直径,以使得副油缸的一端的油能够进入副油缸的另一端。该系统可以自动排气补油,操作方便,更加安全,避免排气时造成油液的浪费与污染。
