[0018] Example 1

[0019] Referring to FIG1, which is the first embodiment of this application, this embodiment provides a tool for disassembling a water pump bearing, which includes an installation unit 100 movably disposed on the outer surface of a deep well pump coupling, and a disassembly unit 200 mounted on the outer surface of the deep well pump coupling via the installation unit 100; the disassembly unit 200 disassembles the bearing disposed on the deep well pump coupling.

[0020] It should be noted that the disassembly unit 200 is mounted on the exterior of the deep well pump coupling via the mounting unit 100. This not only facilitates the installation of the disassembly unit 200, but also allows for quick disassembly after the deep well pump coupling is disassembled, effectively improving work efficiency and reducing preparation work during disassembly.

[0021] In summary, the advantages of the tool for disassembling water pump bearings proposed in this application are that by adopting an externally mounted disassembly unit, not only can the preparation work before disassembly be reduced, but the disassembly work can also be simplified, avoiding the problem of equipment damage caused by violent disassembly, and greatly improving work efficiency.

[0022] Example 2

[0023] Referring to Figures 2 to 5, this is the second embodiment of the present application. This embodiment provides a tool for disassembling water pump bearings, which includes an installation unit 100 movably disposed on the outer surface of a deep well pump coupling, and a disassembly unit 200 mounted on the outer surface of the deep well pump coupling via the installation unit 100; the disassembly unit 200 disassembles the bearings disposed on the deep well pump coupling.

[0024] In one embodiment, the disassembly unit 200 is mounted on the exterior of the deep well pump coupling via the mounting unit 100. This not only facilitates the installation of the disassembly unit 200, but also allows for quick disassembly after the deep well pump coupling is disassembled, effectively improving work efficiency and reducing preparation work during disassembly.

[0025] In one embodiment, the installation unit 100 includes a limiting frame assembly 101 and a positioning component 102 disposed on the outside of the limiting frame assembly 101; the positioning component 102 is used to limit and fix the limiting frame assembly 101.

[0026] In one embodiment, the disassembly unit 200 includes an outer casing assembly 201 and an extension assembly 202 disposed at one end of the outer casing assembly 201; the mounting unit 100 is used to position and limit the disassembly unit 200.

[0027] It should be noted that the disassembly unit 200 is movably installed on the outside of the installation unit 100, which facilitates the assembly and disassembly between the disassembly unit 200 and the installation unit 100, and can effectively reduce the preparation work before disassembly. The outer sleeve assembly 201, together with the extension assembly 202, can quickly complete the disassembly and assembly, which can effectively avoid the problem of equipment damage caused by violent disassembly.

[0028] In one embodiment, the disassembly unit 200 includes an outer casing assembly 201 and an extension assembly 202 disposed at one end of the outer casing assembly 201.

[0029] The outer casing 201 is used to adjust the position of the extension 202.

[0030] It should be noted that the outer casing component 201 facilitates the adjustment of the extension component 202, and the outer casing component 201 can also serve as a positioning tool to avoid increasing the difficulty of disassembly due to positional deviation.

[0031] In one embodiment, the outer sleeve assembly 201, in conjunction with the extension assembly 202, can be used as a disassembly tool for deep well pump couplings with different spacings.

[0032] In one embodiment, the limiting frame assembly (101) includes a support member (101a) and an anti-slip member (101b) disposed at the bottom of the support member (101a);

[0033] The bracket 101a includes an arc-shaped ring 101a-1 and limiting members 101a-2 provided on both sides of the arc-shaped ring 101a-1, wherein one side of the limiting member 101a-2 is provided with an arc shape.

[0034] It should be noted that the arc-shaped ring 101a-1 is arc-shaped in order to better fit on the output shaft, and the limiting member 101a-2 is arc-shaped in order to better limit the disassembly unit 200.

[0035] Furthermore, the positioning component 102 includes a first threaded hole 102a opened on the outer side of the arc-shaped ring 101a-1, and a fixing bolt 102b threadedly connected to the first threaded hole 102a, wherein at least two sets of the first threaded holes 102a are provided, and the first threaded holes 102a are symmetrically opened.

[0036] It should be noted that the first threaded hole 102a is provided to facilitate the installation of the fixing bolt 102b. The first threaded hole 102a, together with the fixing bolt 102b, can limit and fix the arc ring 101a-1 installed on the output shaft, so as to prevent the arc ring 101a-1 from shifting during use and reduce the impact on disassembly.

[0037] Furthermore, the outer sleeve assembly 201 includes a sleeve 201a, a positioning post 201b disposed at one end of the sleeve 201a, a second threaded hole 201c opened at one end of the sleeve 201a, and a hexagonal block 201d fixedly connected to the sleeve 201a; the center of the positioning post 201b is located on the central axis of the sleeve 201a.

[0038] It should be noted that positioning pin 201b and sleeve 201a are at the same level, which ensures that the direction of force is consistent during disassembly, reduces the impact on disassembly, and improves disassembly efficiency. Furthermore, the setting of hexagonal block 201d can greatly facilitate the rotation of sleeve 201a, making it easier for users to rotate sleeve 201a with other auxiliary tools.

[0039] In one embodiment, the extension assembly 202 includes a threaded rod 202a threadedly connected to a second threaded hole 201c, a first hexagonal nut 202b disposed outside the threaded rod 202a, and a second hexagonal nut 202c disposed outside the threaded rod 202a.

[0040] It should be noted that the threaded rod 202a facilitates the connection with the sleeve fitting 201a and allows for adjustment according to different spacings, thus enhancing practicality.

[0041] In one embodiment, the positioning post 201b and the sleeve 201a are at the same level, which ensures that the direction of force is consistent during disassembly, reduces the impact on disassembly, and improves disassembly efficiency. Furthermore, the hexagonal block 201d greatly facilitates the rotation of the sleeve 201a, making it easier for the user to rotate the sleeve 201a with other auxiliary tools. At the same time, it can also be used in conjunction with the threaded rod 202a to achieve a storage effect, reduce the size of the tool, and make it easy to carry.

[0042] It should be noted that the threads of the first hexagonal nut 202b and the second hexagonal nut 202c are opposite to the threads inside the second threaded hole 201c.

[0043] During installation, the arc-shaped ring 101a-1 is placed on the output shaft of the deep well pump coupling, and then the arc-shaped ring 101a-1 is fixed on the output shaft of the deep well pump coupling by the fixing bolt 102b. Finally, the sleeve fitting 201a is placed on the limiting member 101a-2.

[0044] In use, place the arc-shaped ring 101a-1 on the output shaft of the deep well pump coupling. After connecting it to the first threaded hole 102a with the fixing bolt 102b, fix the arc-shaped ring 101a-1 on the output shaft of the deep well pump coupling. Place the sleeve fitting 201a on the limiting part 101a-2. Adjust the first hexagonal nut 202b with a wrench, and adjust the second hexagonal nut 202c with a wrench so that the end of the second hexagonal nut 202c away from the threaded rod 202a is at a suitable length. Rotate the hexagonal block 201d with a wrench, and clamp the second nut 202c with another wrench. When the sleeve fitting 201a rotates, the second hexagonal nut 202c does not move due to the obstruction of the first hexagonal nut 202b, thus playing a limiting role. At the same time, the threaded rod 202a moves outward, pushing out the deep well pump coupling.

[0045] In summary, the beneficial effects of the tool for disassembling water pump bearings proposed in this application are as follows: as a disassembly tool, it does not bear excessive radial force, thus requiring lower material rigidity and strength. It is suitable for locations with narrow spaces and many obstacles, saving space and avoiding the inconvenience caused by hard tools such as jacks and copper rods or hot disassembly methods. It can effectively reduce labor costs, improve work efficiency while ensuring disassembly quality, and allow the motor and pump body to be evenly stressed. When the yield limit of the coupling rust is reached, the pump and motor can be separated, avoiding mechanical damage and equipment damage caused by striking tools. It saves time and effort for deep well pump maintenance.

[0047] Referring to FIG6, a third embodiment of this application is provided, which provides a method for using a tool for disassembling a water pump bearing, including supporting and limiting the disassembly unit 200 by means of the mounting unit 100;

[0048] After the outer casing assembly 201 is adjusted to the required position, the extension assembly 202 is further adjusted to disassemble the bearing.

[0049] It should be noted that the disassembly unit 200 is mounted on the exterior of the deep well pump coupling via the mounting unit 100. This not only facilitates the installation of the disassembly unit 200, but also allows for quick disassembly after the deep well pump coupling is disassembled. In addition, the mounting unit 100 also provides a load-bearing function for the disassembly unit 200, making it convenient for users to use.

[0050] In summary, the advantages of the tool for disassembling water pump bearings proposed in this application are that it is suitable for locations with narrow spaces and many obstacles, saves space, avoids the inconvenience caused by hard tools such as jacks and copper rods or hot disassembly methods, effectively reduces labor costs, improves work efficiency while ensuring disassembly quality, and allows the motor and pump body to be evenly stressed. When the yield limit of the coupling rust is reached, the pump and motor can be separated, avoiding mechanical damage and equipment damage caused by striking tools.

[0051] The beneficial effects of this application are as follows: As a disassembly tool, it does not bear excessive radial force, thus requiring lower material rigidity and strength. It is suitable for locations with narrow spaces and many obstacles, saving space and avoiding the inconvenience caused by hard tools such as jacks and copper rods or hot disassembly methods. It can effectively reduce manpower and improve work efficiency while ensuring disassembly quality. It can make the motor and pump body bear force evenly. When the yield limit of the coupling rust is reached, the pump and motor can be separated, avoiding mechanical damage and equipment damage caused by striking tools. It saves time and effort for deep well pump maintenance.
