Description

Technical Field

[0001] The utility model belongs to the technical field of mechanical tools, and in particular relates to a rotor coupling pin sleeve disassembly and assembly tool. Background Art

[0002] During the reinstallation of the hydro-turbine generator set, the rotor coupling pin sleeve is a difficult link to install. Whether the installation is smooth is affected by many factors, including the existence of high points on the pin sleeve surface, the tilted installation of the pin sleeve, the non-concentricity of the rotor pin hole and the generator shaft pin hole, etc., which will affect the efficiency of the rotor coupling pin sleeve reinstallation; therefore, the pin sleeve needs to be frequently disassembled and assembled during installation to adjust the state of the pin sleeve. In view of this situation, the traditional method is to design a separate tool for the installation and disassembly of the rotor coupling pin sleeve. This method can normally perform the disassembly and top-pressing installation of the pin sleeve, but the operation is cumbersome and requires switching the tool back and forth according to the disassembly or installation process of the pin sleeve. Therefore, it is necessary to design a tool that can complete both the disassembly of the pin sleeve and the top-pressing installation of the pin sleeve, reduce the back-and-forth switching of tools during the installation of the pin sleeve, and improve the efficiency of the pin sleeve installation. Summary of the invention

[0003] In view of the problem that the above-mentioned rotor coupling pin sleeve disassembly and assembly requires two sets of tools and is inefficient, the utility model provides a rotor coupling pin sleeve disassembly and assembly tool, including a top pressure plate, the top pressure plate is a circular ring sheet structure, the inner ring part of which is provided with a top pressure cylinder, and a through hole is opened on the top pressure plate, and the through hole is a threaded hole.

[0004] As a preferred solution, the pressing cylinder is a columnar structure with one end closed and the other end open, and its inner wall is provided with threads.

[0005] As a preferred solution, the thickness of the pressing cylinder is at least 20 mm.

[0006] As a preferred solution, the top pressure plate is also fixedly provided with a reinforcing rib, and the other side of the reinforcing rib is fixedly connected to the top pressure cylinder.

[0007] As a preferred solution, the angle between the reinforcing ribs is 55-65°, the reinforcing ribs are two adjacent reinforcing ribs located on the same side of the through hole, and the thickness of the reinforcing ribs is at least 10 mm.

[0008] As a preferred solution, the inner wall diameter of the open end of the pressure cylinder is the same as the diameter of the rotor coupling bolt.

[0009] Beneficial effects of the utility model:

[0010] The tool can complete the disassembly and installation of the rotor coupling pin sleeve, integrating the functions of two tools into one tool. During the installation process, there is no need to replace the tool, which improves the operating efficiency. The tool is suitable for the disassembly and installation of the rotor coupling pin sleeve of each power station and has strong versatility. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] Furthermore, the pressing cylinder 2 is a columnar structure with one end closed and the other end open, and its inner wall is provided with threads to meet two different usage conditions of installation and disassembly.

[0020] Furthermore, the thickness of the pressing tube 2 is 20 mm, which makes the pressing tube 2 light enough to reduce weight and facilitate carrying while meeting the strength requirements.

[0021] Furthermore, a reinforcing rib 4 is fixedly provided on the top pressure plate 1 , and the other side of the reinforcing rib 4 is fixedly connected to the top pressure cylinder 2 .

While meeting the strength requirements, the reinforcing ribs 4 are light enough to reduce weight and facilitate carrying.

[0023] Furthermore, the inner wall diameter of the open end of the pressure cylinder 2 is the same as the diameter of the rotor coupling bolt, so that the open end can be screwed into the top of the rotor coupling bolt 6.

[0024] The above tool is used in the following way: during the disassembly process, a hydraulic jack 5 is set up on the top of the rotor coupling bolt 6, and then a screw is installed in the through hole 3, and the other end of the screw is connected to the rotor coupling pin sleeve 7, and then the hydraulic jack 5 is raised to complete the disassembly of the rotor coupling pin sleeve 7;

[0025] During the installation process, the open end of the top pressure cylinder 2 is screwed into the rotor coupling bolt 6, and then two hydraulic jacks 5 are symmetrically set up between the top pressure plate 1 and the rotor coupling pin sleeve 7, and then the hydraulic jacks 5 are raised to complete the installation of the rotor coupling pin sleeve 7.
