[0019] The technical solution of the utility model will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] In the description of the present invention, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the present invention. In addition, the terms "first", "second", and "third" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.

[0021] In the description of the present utility model, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected" and "connected" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal connection of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances. In addition, the technical features involved in the different embodiments of the present utility model described below can be combined with each other as long as they do not conflict with each other.

[0022] See also Figure 1 and Figure 2 A low-speed shaft 4 auxiliary assembly device shown in a preferred embodiment of the present application includes a support frame 1, a connecting column 2 and at least one lifting ring 3. The support frame 1 is provided with a supporting cross frame 11 and a supporting vertical frame 12 connected to the supporting cross frame 11. One end of the connecting column 2 is rotatably arranged at the end of the supporting vertical frame 12, and the other end of the connecting column 2 is provided with a thread groove 21 for screwing with a stud 41 at the end of the low-speed shaft 4. The at least one lifting ring 3 is arranged on the supporting cross frame 11.

[0023] Since the low-speed shaft 4 workpiece is heavy, two operators are required to lift the two ends of the low-speed shaft 4 workpiece from one side of the gearbox volute during the existing assembly process. When inserting one end of the low-speed shaft 4 workpiece into the gearbox volute, one of the operators needs to change hands for a second time and continue to lift the one end of the low-speed shaft 4 workpiece that has just been inserted from the other side of the gearbox volute until the low-speed shaft 4 workpiece is assembled in place. The assembly process not only requires two workers, but is also time-consuming, labor-intensive, and troublesome.

[0024] Therefore, according to the solution of the embodiment of the utility model, the low-speed shaft 4 is auxiliary fixed by screwing the stud 41 on the low-speed shaft 4 into the threaded groove 21 in the connecting column 2, and then the lifting ring 3 on the supporting cross frame 11 is hung with the help of a crane. Only a single operator is required to push the auxiliary assembly device to drive the low-speed shaft 4 to pass through the gear box volute to complete the workpiece assembly.

[0025] The following is a detailed description with specific embodiments:

[0026] See also Figure 1 and Figure 2, the connecting column 2 is perpendicular to the central axis of the supporting vertical frame 12, and the central axes of the connecting column 2, the supporting vertical frame 12 and the supporting horizontal frame 11 are located on the same vertical plane. The connecting column 2 is perpendicular to the central axis of the supporting vertical frame 12, which can ensure that the low-speed shaft 4 remains horizontal when it is auxiliary fixed, so that it can be subsequently assembled through the gear box volute. The central axes of the connecting column 2, the supporting vertical frame 12 and the supporting horizontal frame 11 are located on the same vertical plane, which can ensure that the center of gravity of the auxiliary assembly device can still be maintained on the same vertical plane after auxiliary fixing of the low-speed shaft 4, preventing the center of gravity of the device from tilting after auxiliary fixing of the low-speed shaft 4, affecting the subsequent assembly process of the low-speed shaft 4.

[0027] See also Figure 2 The other end face of the connecting column 2 can fit with the end face of the impeller 42 on the low-speed shaft 4, which can increase the contact area between the connecting column 2 and the end face of the impeller 42, making the auxiliary fixation of the low-speed shaft 4 more stable and preventing the low-speed shaft 4 from being deformed at the stud 41 due to excessive deadweight after auxiliary fixation.

[0028] See also Figure 1 and Figure 2 A connecting plate 13 is provided between the supporting cross frame 11 and the supporting vertical frame 12, and the connecting plate 13 is used to connect and fix the supporting cross frame 11 and the supporting vertical frame 12. Specifically, in this embodiment, the supporting vertical frame 12 is located below the supporting cross frame 11, and the supporting frame 1 composed of the supporting vertical frame 12 and the supporting cross frame 11 is an L-shaped structure as a whole. Connecting plates 13 are provided on both sides of the connection between the supporting cross frame 11 and the supporting vertical frame 12 for connection and reinforcement. The supporting cross frame 11 and the supporting vertical frame 12 are made of channel steel.

[0029] See also Figure 2 The end of the support frame 12 is provided with a rotating shaft 14, and one end of the connecting column 2 is rotatably arranged on the support frame 12 through the rotating shaft 14. Figure 1 and Figure 2 , a number of connection handles 22 are arranged around the connection column 2. When in use, first use the crane to hang the lifting ring 3 at a suitable position on the supporting horizontal frame 11, move the device as a whole to the stud 41 at one end of the low-speed shaft 4, and align the stud 41 with the thread groove 21 on the connection column 2, and then rotate the connection handle 22 on the connection column 2 so that the stud 41 is screwed into the bottom of the thread groove 21, and the end face of the other end of the connection column 2 fits with the end face of the impeller 42 on the low-speed shaft 4. Then use the crane to move the low-speed shaft 4 to the gearbox volute, and a single operator holds the supporting vertical frame 12 to drive the low-speed shaft 4 to move, and the low-speed shaft 4 passes through the gearbox volute to complete the workpiece assembly.

[0030] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0031] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
