Combined crawler belt walking mechanism with omni-directional movement and platform thereof

The invention provides a combined crawler belt walking mechanism with omni-directional movement and a platform thereof. The combined crawler belt walking mechanism comprises a crawler belt set, a driving wheel set, a main support, an inducer set, a tensioning mechanism, load-bearing wheel sets and belt-supporting wheel sets. The crawler belt set is composed of an outer side sub-crawler belt and aninner side sub-crawler belt, wherein the two independent belts are longitudinally and symmetrically arranged in the center axis of the crawler belt set, and formed by multiple crawler belt plates through hinge pins in a hinged mode, an idler wheel support is design on each crawler belt plate, and two cylindrical idler wheels capable of rotating freely are installed on each idler wheel support, and installed on the two sides of each idler wheel support respectively. Through the combined crawler belt walking mechanism, the problems that in the prior art, an existing crawler belt-type moving platform is too large in dim
