Problems solved by technology

[0002] Jack is a common tool used in the installation, disassembly, and adjustment of mechanical equipment. At present, the mechanical and split hydraulic jacks provided by tool manufacturers have the disadvantages of large size, heavy weight, and inapplicability for narrow space operations. Moreover, nuclear power plants There are a lot of equipment, and the space for installation and maintenance of many equipment is narrow. The required jacks are of various types, and the purchased finished jacks cannot meet the needs of some equipment during installation and maintenance.

Embodiment

[0023] Such as figure 1 As shown, a simple jack device for a nuclear power plant includes a nut base 1, a screw jack 2 and a spherical top bead 3, one end of the screw jack 2 is threadedly connected to the nut base 1, and the other end is provided with a spherical jack 3 for placing spherical groove.

[0024] The screw jack 2 is provided with an external thread, and the nut base 1 is provided with an internal thread corresponding to the external thread of the jack screw. Both the external thread and the internal thread are trapezoidal threads.

[0025] The spherical groove is arranged at the center of the end face of the screw mandrel 2 . The center of the spherical top bead 3 is located inside the groove. The vertical distance between the center of the ball and the end face of the screw mandrel 2 is 0.5mm.

[0026] There is a gap between the spherical groove and the spherical top bead 3 . Lubricant is filled in the gap. The spherical top ball 3 is a bearing ball.
