Hydraulic power pack of three-dimensional adjusting machine

Abstract

The invention discloses a hydraulic pump station for a three-dimensional adjusting machine, which includes a fuel tank, a high-pressure pump and a low-pressure pump, the high-pressure pump and the low-pressure pump are respectively arranged on the fuel tank; it includes a high-pressure oil pump system and a low-pressure oil pump system, and the high-pressure oil pump The system is composed of a high-pressure pump, a Z-direction vertical jacking circuit, and two horizontal moving circuits; the low-pressure oil pump system is composed of a low-pressure pump, a walking circuit, and a jacking action circuit; the present invention combines the high-pressure pump station and the low-pressure pump station integrated together. Low-pressure pump station: low-pressure valve group controls the lifting of the jacking cylinder and the forward and reverse rotation of the hydraulic motor; high-pressure pump station: Z-direction valve is equipped with a balance valve to control the rise and fall of the Z-direction jack, and the valve group can make the weight drop smoothly And it has the function of maintaining pressure; the X﹑Y valve group controls the forward and backward of the horizontal cylinder.

Description

technical field [0001] The invention relates to a hydraulic pump station, in particular to a hydraulic pump station for a three-dimensional adjustment machine, and belongs to the technical field of hydraulic equipment. Background technique [0002] With the improvement of the manufacturing capacity of the shipbuilding industry, there have been more and more seam welding of large components ranging from hundreds of tons to thousands of tons. However, the current lifting capacity of large cranes cannot meet the requirements of the above working conditions, so there is a problem of seam welding of large components. For large components that exceed the range of lifting capacity, manufacturers usually use three-dimensional adjustment machines for cost and feasibility considerations to adjust and position large components up and down, front and back, and left and right. As a ship lifting equipment, the three-dimensional adjustment machine has the advantages of scalable lifting ca...

AI Technical Summary

Problems solved by technology

Due to the limitations of the site environment, the three-dimensional adjustment machine must not only have the function of walking, but also often require the component to maintain a certain height within a certain period of time during the lifting and positioning process of the component, and the horizontal direction has the function of adjustment. Ordinary It is difficult for the hydraulic pump station to realize all the above functions at the same time
