[0018] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of the technical features being referred to. Thus, a feature specified as "first" or "second" may explicitly or implicitly include one or more of such features. In the description of this utility model, "plurality" means two or more, unless otherwise specifically defined.

[0019] In this utility model, unless otherwise specified or limited, the terms "installed," "connected," "connect," "fixed," etc. should be understood in a broad sense. For example, they can refer to fixed connection, detachable connection, or integration; mechanical connection, electrical connection; direct connection, indirect connection through an intermediate medium, internal communication between two components, or interaction between two components. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on specific circumstances.

[0020] In the present invention, unless otherwise expressly specified or limited, when a first feature is "above" or "below" a second feature, it may mean that the first and second features are in direct contact, or the first and second features are in indirect contact through an intermediary. Furthermore, when a first feature is "above," "above," or "above" a second feature, it may mean that the first feature is directly above or diagonally above the second feature, or simply means that the first feature is at a higher level than the second feature.

[0021] Example 1:

[0022] like Figure 1 -2 shows a large nut 2 installation tool, including a rotating shaft 4 and a lifting assembly, one end of the rotating shaft 4 extends into the inner hole of the nut 2 and is used to support the nut 2; the lifting assembly is located above the supporting assembly, and the lifting assembly includes a suspension rod 7, a connecting rod 6 and a mounting frame 8, the suspension rod 7 is horizontally arranged, the connecting rod 6 connects the suspension rod 7 and the mounting frame 8, the mounting frame 8 is located below the suspension rod 7, and the rotating shaft 4 is arranged on the side of the mounting frame 8 facing the nut 2.

[0023] When assembling the nut 2, you only need to put the sling on the suspension rod 7, lift the nut 2 to the end of the pull rod 1 by the crane, manually align the nut 2 and the pull rod 1 accurately, and rotate the nut 2 to make the internal thread of the inner hole of the nut 2 screw into the external thread of the pull rod 1, so as to realize the rapid assembly of the nut 2. When the nut 2 enters a certain length, the rotating shaft 4 can be withdrawn.

[0024] The large nut 2 installation tool of this embodiment supports the nut 2 through the rotating shaft 4, and cooperates with the lifting assembly to lift the nut 2 to the end of the pull rod 1 so that the nut 2 can rotate in the air, thereby realizing rapid assembly of the large nut 2 and the pull rod 1.

[0025] The rotating shaft 4 is sleeved with a sleeve 3, and bearings 5 are provided at both ends of the rotating shaft 4. The inner wall of the bearing 5 is fixed to the rotating shaft 4, and the outer wall of the bearing 5 is fixed to the inner wall of the sleeve 3; the sleeve 3 can rotate around the rotating shaft 4 to avoid thread wear of the inner hole of the nut 2.

[0026] There are swing arms hinged on both sides of the mounting frame 8. The swing arm is provided with a spring at one end relative to the mounting frame 8. The top of the spring is set in the middle of the suspension rod 7. The swing arm is provided with an auxiliary shaft. One end of the auxiliary shaft extends into the inner hole of the nut 2. The other end of the auxiliary shaft is provided with an auxiliary bearing 5. The inner wall of the auxiliary bearing 5 is fixed to the auxiliary shaft, and the inner wall of the bearing 5 is fixed to the swing arm; the swing arm can swing downward around the mounting frame 8 so that the auxiliary shaft adapts to the inner hole of the nut 2, and the auxiliary rotating shaft 4 supports the nut 2 to prevent the nut 2 from shaking when rotating.

[0027] The outer wall of the sleeve 3 is provided with a rubber buffer sleeve; the provision of the rubber buffer sleeve can prevent the thread of the inner hole of the nut 2 from directly contacting the outer wall of the sleeve 3, thereby preventing the thread of the inner hole of the nut 2 from wearing.

[0028] The suspension rod 7 is provided with a stopper at one end relative to the connecting rod 6, and the stopper is fixed below the suspension rod 7; the setting of the stopper can prevent the suspension rope from detaching from the suspension belt.

[0029] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any form. Any simple modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention are within the scope of the technical solution of the present invention.
