Abstract

The invention discloses a three-dimensional hydraulic jacking machine and a three-dimensional jacking system. The three-dimensional hydraulic jacking machine comprises a frame, a main oil cylinder located on the top of the frame and suitable for sliding horizontally along the surface of the frame, a first lateral oil cylinder and a second lateral oil cylinder located on the circumferential side face of the main oil cylinder and a walking wheel assembly suitable for driving the frame to walk. One ends of the first lateral oil cylinder and the second lateral oil cylinder far away from the main oil cylinder are connected to the frame; and the main oil cylinder stretches along a Z direction, the first lateral oil cylinder stretches along an X direction and the second lateral oil cylinder stretches along a Y direction. The three-dimensional hydraulic jacking machine is compact in structure and flexible to lift, and multiple three-dimensional hydraulic jacking machines can be matched to operate to improve the lifting tonnage, so that the three-dimensional hydraulic jacking machine is suitable for centering and folding work of subsections of ship bodies and bridges and large steel structural parts.

Description

technical field [0001] The invention relates to special hydraulic equipment, which belongs to the field of installation of ship hull bridge sections and large steel structure parts, and in particular relates to a three-dimensional hydraulic jacking machine and a three-dimensional jacking system. Background technique [0002] The three-dimensional hydraulic jacking machine is mainly used for the lifting and centering of the hull bridge section and the closing operation of large steel structure parts. The cooperation of multiple units can lift and move the hull bridge section and large steel structure parts to complete the hull bridge Centering and closing work of segments and large steel structures. [0003] In recent years, the weight of hull bridge sections and large steel structural parts has been increasing, and the function and lifting capacity of the equipment used for installation have also increased. important factor in development. Traditional hydraulic jacks are o...
