[0022] Example 1:

[0023] like Figures 1 to 4 As shown, an auxiliary installation tool for a giant nut includes a lifting pile 2, a giant nut bearing mechanism 1, and a counterweight mechanism 4; the axis of the lifting pile 2 is perpendicular to the horizontal plane; the giant nut bearing mechanism 1 and the counterweight mechanism 4 are respectively installed on opposite sides of the lifting pile 2 in the horizontal direction.

[0024] In this embodiment, the giant nut bearing mechanism 1 includes a main shaft 101, ball bearings 102, and a sleeve 103. The main shaft 101 has a cylindrical structure, and several annular grooves 105 are evenly distributed and coaxially formed on the side wall of the main shaft 101 along its axial direction. Several ball bearings 102 are evenly distributed and rolled in the annular grooves 105 along their circumferential direction. The hollow part of the sleeve 103 has a cylindrical structure, and the sleeve 103 is coaxially sleeved on the outside of the main shaft 101. The inner side wall of the sleeve 103 is in contact with the ball bearings 102. One end of the main shaft 101 is mounted on the pile 2, and the axis of the main shaft 101 is perpendicular to the axis of the pile 2.

[0025] Specifically, retaining rings 104 are provided on the inner sidewalls of both ends of the sleeve 103, and the ball bearing 102 is located between the retaining rings 104 at both ends of the sleeve 103, which can prevent the sleeve 103 from falling off the main shaft 101; the sidewall of the annular groove 105 fits against the sidewall of the ball bearing 102.

[0026] In addition, the sleeve 103 is made of metal. In this embodiment, the metal is copper, that is, the sleeve 103 in this embodiment is a copper sleeve, which enables the sleeve 103 to protect the internal thread of the giant nut and at the same time increase the friction of the outer surface of the sleeve 103 to prevent the giant nut from shifting laterally.
