Description
Technical Field
[0001] The utility model relates to the technical field of water pump impeller shafts, and more specifically, to a large water pump impeller shaft maintenance device. Background Art
[0002] The impeller shaft of a water pump is a component that connects the impeller and the water pump shaft. The impeller shaft of a water pump plays a key role in the water pump. In the current industrial field, the impeller shaft of a water pump is an indispensable component of the hydraulic system, and its stability and reliability are directly related to the operating efficiency of the entire hydraulic system. However, due to the wide variety of types and large size differences of the impeller shaft of the water pump, the clamping and fixing of the impeller shaft becomes particularly complicated during the repair and maintenance process. Although the existing large-scale water pump impeller shaft maintenance device can meet the basic maintenance needs to a certain extent, the limitations of its clamping device are gradually highlighted in practical applications. This maintenance device often adopts a unified clamping structure. Although it has a good clamping effect for the impeller shaft size within a fixed range, once it encounters an impeller shaft beyond this range, it seems to be unable to do its job. Specifically, when facing a smaller-sized water pump impeller shaft, the existing clamping device may damage the surface of the impeller shaft due to excessive clamping force, and even cause the shaft body to deform, thereby further affecting the performance of the water pump. For larger impeller shafts, the clamping device may not be able to firmly fix the impeller shaft due to insufficient clamping force, which poses a safety hazard during the maintenance process and reduces the efficiency and accuracy of the maintenance. More seriously, this limitation not only affects the smooth progress of the maintenance, but also limits the scope of use of the maintenance device. In actual applications, due to the wide variety of water pump impeller shafts and large size differences, if the water pump impeller shafts of different sizes cannot be fixed according to the actual situation, the practicality of this maintenance device will be greatly reduced.

When maintenance personnel can perform maintenance from different angles comfortably and stably, they can better control tools and equipment and reduce the risk of accidents, thereby enhancing the safety of maintenance work and ensuring the health and safety of maintenance personnel.

[0023] When in use, the staff starts the motor 9, and the power generated by the motor 9 makes the main gear 8 rotate. Since the main gear 8 is meshed with the slave gear 7, the main gear 8 drives the slave gear 7 to rotate synchronously while rotating. The power of the slave gear 7 makes the threaded rod 3 rotate through the connecting shaft 6, and the sleeve plate 4 on the surface of the threaded rod 3 moves on the surface of the threaded rod 3, so as to adjust the distance between the two shells 5. After adjusting to the appropriate distance, the staff places the water pump impeller shaft on the surface of the lower arc plate 14, and then rotates the handle 17 to make the threaded rod 16 rotate inside the sleeve 15 and move downward, and clamps the top of the water pump impeller shaft through the pressure plate 18 at the bottom, and then the staff repairs the clamped water pump impeller shaft;
[0024] The power generated by the motor 9 causes the slave gear 7 meshing with the main gear 8 to rotate, and the power of the slave gear 7 causes the threaded rod 3 to rotate through the connecting shaft 6, and the socket plate 4 on the surface of the threaded rod 3 moves to adjust the distance between the two shells 5, and then the water pump impeller shaft is placed on the surface of the lower arc plate 14, and then the handle 17 is turned to make the threaded rod 16 move downward and fix the water pump impeller shaft through the pressure plate 18, and then the staff performs maintenance on it.

Compared with the traditional device, this device can make it easier for maintenance personnel to approach and contact the parts that need to be repaired by adjusting the height position of the impeller shaft, thereby increasing the accessibility of maintenance work. At the same time, by adjusting the height position of the impeller shaft, maintenance personnel can more easily find these angles or postures, thereby reducing the difficulty of maintenance, thereby improving the efficiency of maintenance work and shortening maintenance time. When maintenance personnel can perform maintenance from different angles comfortably and stably, they can better control tools and equipment and reduce the risk of accidents, thereby enhancing the safety of maintenance work and ensuring the health and safety of maintenance personnel.

Since the main gear 8 is meshed with the slave gear 7, the main gear 8 drives the slave gear 7 to rotate synchronously while rotating. The power of the slave gear 7 makes the threaded rod 3 rotate through the connecting shaft 6, and the socket plate 4 on the surface of the threaded rod 3 moves on the surface of the threaded rod 3, so as to adjust the distance between the two shells 5. After adjusting to the appropriate distance, the staff places the water pump impeller shaft on the surface of the lower arc plate 14, and then turns the handle 17 to make the threaded rod 16 rotate inside the sleeve 15 and move downward, and clamps the top of the water pump impeller shaft through the pressure plate 18 at the bottom, and then the staff repairs the clamped water pump impeller shaft.
[0042] When the height of the water pump impeller shaft needs to be adjusted, the staff starts the motor 23. The power generated by the motor 23 causes the main gear 22 to rotate. Since the main gear 22 is meshed with the slave gear 21, the main gear 22 drives the slave gear 21 to rotate synchronously while rotating. The power of the slave gear 21 causes the threaded rod 3 19 to rotate through the connecting shaft 20. The rotation of the threaded rod 3 19 drives the socket block 11 on its surface to move, thereby adjusting the position of the water pump impeller shaft.
