Hydraulic machine with multi-housing multi-directional bearing racks

The invention discloses a hydraulic machine with multi-housing multi-directional bearing racks. The hydraulic machine comprises at least two single-housing horizontal racks, at least one single-housing vertical rack, a main working cylinder, return cylinders and horizontal cylinders. Archways of the at least one single-housing vertical rack are arranged in parallel and are fixedly connected to form a multi-housing vertical rack, and the at least two single-housing horizontal racks are arranged on the two sides of the multi-housing vertical rack in parallel and fixedly connected to form a multi-housing horizontal rack. Horizontal loads and vertical loads are loaded on the two completely independent racks of the multi-housing horizontal rack and the multi-housing vertical rack respectively, and accordingly, the requirement for the rigidity of the racks is reduced, the large-tonnage hydraulic machine rack overall weight is reduced effectively, and the hydraulic machine rack own strength is high; horizontal loads transmitted by the horizontal cylinders are born by the multi-archway horizontal rack, so that the bearing capacity is high, and the multi-housing horizontal rack cannot be damaged even if being subjected to huge loads.
