More Information
Summary:The utility model relates to the technical field of three-dimensional jacks, and discloses a three-dimensional jack for jacking and twisting a frame structure box bridge, which comprises a bottom plate, a support plate is mounted at the front end of the upper surface of the bottom plate, a first hydraulic cylinder is mounted on the front surface of the support plate, and a support seat is slidably connected to the upper surface of the bottom plate and positioned behind the support plate. A second hydraulic cylinder is slidably connected into the supporting seat, and a third hydraulic cylinder is mounted on the surface of the left side of the supporting seat. By arranging the protection assembly, lubricating oil is added into a protection pad in the protection assembly, and the protection pad is tightly attached to sliding rods of the three hydraulic cylinders under the action of the extrusion pad and lubricates the sliding rods; the jack can be lubricated for a long time after oil is added once, an electric p
