Problems solved by technology
[0004] For the design of the hydraulic control system of this equipment, some manufacturers at home and abroad currently design the working pressure below 31.5MPa, so the volume of the vertical main jacking cylinder is huge, resulting in a large and cumbersome machine, resulting in great labor intensity for operators. The cost tonnage ratio is low, and at the same time, the operation is not flexible, resulting in a decline in production efficiency; in view of this situation, the existing domestic manufacturers use high and low pressure double pumps as power sources, and the ultrahigh pressure of the pump reaches 70MPa, and is equipped with ultrahigh pressure components at the same time , to realize the vertical jacking cylinder working under ultra-high pressure, so as to reduce the turning radius of the vertical jacking cylinder and reduce the volume and weight of the whole machine
However, in my country, the quality of ultra-high pressure hydraulic components is far less mature than that of medium and high pressure hydraulic components, and the supply of goods is scarce, the price is expensive, and the service life and failure rate cannot satisfy users.
At the same time, compared with conventional valves, ultra-high pressure valves are more difficult to seal, have stricter requirements on the use environment, have a high relative failure rate, and cannot guarantee safety

Embodiment Construction
[0014] The present invention will be further described below in conjunction with accompanying drawing:
[0015] as attached figure 1 As shown, the hydraulic system of the three-dimensional adjustment machine includes a hydraulic pump 2, an unloading circuit, a vertical lifting circuit (Z direction), two horizontal adjustment translation circuits (X direction and Y direction), a total of four parallel hydraulic branches .
[0016] The hydraulic pump 2 has an oil suction port and an oil pressure port. The oil suction port extends into the oil tank 13 to absorb the oil source through the oil suction filter. The inlets of the four parallel hydraulic branches are all connected to the oil pressure port of the hydraulic pump 2. The hydraulic pump 2 The oil discharge provides working fluid to each branch circuit, and the return oil of all hydraulic branch circuits flows back to the oil tank 13 through the oil return filter 12 .
[0017] The unloading circuit is composed of an electr...

Description
technical field [0001] The invention relates to a hydraulic control system of a three-dimensional adjusting machine, in particular to a hydraulic control system of an ultra-high pressure three-dimensional adjusting machine. Background technique [0002] The three-dimensional adjustment machine is specially designed for the segmental closing process of the hull of the "Segmented General Shipbuilding Method". The three-dimensional adjustment system, under the control of the computer and the hydraulic system, adjusts the pose of the hull segment from three dimensions and six degrees of freedom, and realizes precise positioning and closure between segments and between segments and the hull. Improve the traditional segmental closing and loading method. This equipment can significantly improve work efficiency, reduce the occupation time of large gantry cranes, reduce labor intensity, and promote occupational health. [0003] It can also be widely used in the butt joint assembly ...
