Self-loading and self-unloading type crawler chassis
2017
A self-loading and self-unloading type crawler chassis comprises a right crawler beam, a left crawler beam and a middle frame; the middle frame is connected with a main machine structure needing bearing; the middle frame is arranged between the right crawler beam and the left crawler beam and keeps an interval with the ground; the right crawler beam and the left crawler beam are detachably connected with the middle frame; the middle frame is provided with a supporting device having a folding state and an unfolding state; when in the folding state, the supporting device draws back to the middle frame and does not make contact with the ground; and when in the unfolding state, the middle frame is supported on the ground through the supporting device, the supporting device supports the whole crawler chassis and the weight of the upper portion, and the original space between the middle frame and the ground is kept. The crawler chassis and the upper main machine structure are loaded onto or unloaded from a transportation flat car through the self structure, and the self-loading and self-unloading type crawler chassis has the characteristics of being simple in structure, convenient to dismount, high in mechanism stability, low in manufacturing cost and the like.
