Description

Technical Field

[0001] This utility model relates to the technical field of motor horizontal coring and leveling devices, and in particular to a horizontal water pump unit motor horizontal coring and leveling device. Background Technology

[0002] As water pump units age, they require regular overhauls. When disassembling the motor of a horizontal water pump unit, horizontal core removal is necessary. For vertical axial flow pumps, the rotor can be lifted out for core removal. However, for horizontal units, the stator needs to be moved horizontally to complete the core removal. Because the motor shaft and impeller shaft are coaxial without a coupling, the rotor weighs about 15 tons, and the air gap between the motor stator and rotor is about 3 mm on each side, after the motor tail bearing is removed, the rotor is no longer supported and will no longer remain horizontal. Placing it on the stator windings can easily damage the motor insulation. Common core removal devices lack leveling functions, making it inconvenient to initially adjust the motor center.

[0003] To address this issue, a horizontal core sampling and leveling device for the motor of a horizontal water pump unit was designed. Utility Model Content

[0004] To address the problems mentioned in the background art, this utility model provides a horizontal water pump unit motor horizontal core-taking and leveling device, which features rapid adjustment of the motor's horizontal center and convenient maintenance.

[0006] A horizontal water pump unit motor horizontal coring and leveling device includes a base, a bracket installed on the top surface of the base, a top plate fixedly installed on the top surface of the bracket, a jack fixedly installed on the top surface of the top plate, a threaded rod installed on the top surface of the top plate, a support plate fixedly installed at the top end of the threaded rod, a bracket fixedly installed on the top surface of the support plate, and a leveling component installed on the surface of the support plate.

[0007] The leveling assembly includes a fixed groove, a level, a first gear, a second gear, a limiting block, and a double-headed rack. The fixed groove is horizontally formed on the surface of the support plate. The level and the fixed groove are matched in shape and size.

It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0024] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0025] Example 1

[0026] This application incorporates existing technologies, such as Figures 1 to 4 As shown, this utility model provides a technical solution: a horizontal water pump unit motor horizontal core leveling device, including a base 1, a bracket 2 installed on the top surface of the base 1, a top plate 3 fixedly installed on the top surface of the bracket 2, a jack 4 fixedly installed on the top surface of the top plate 3, a threaded rod 5 installed on the top surface of the top plate 3, a support plate 6 fixedly installed at the top end of the threaded rod 5, a bracket 7 fixedly installed on the top surface of the support plate 6, and a leveling component 8 installed on the surface of the support plate 6;

[0027] The leveling assembly 8 includes a fixed groove 801, a level 802, a first gear 803, a second gear 804, a limiting block 805, and a double-headed rack 806. The fixed groove 801 is horizontally opened on the surface of the support plate 6. The level 802 and the fixed groove 801 are matched in shape and size. The first gear 803 and the second gear 804 are rotatably connected to the surface of the support plate 6. The limiting block 805 is fixedly installed on the surface of the support plate 6. The surface of the double-headed rack 806 is opened with a limiting groove 807. The limiting block 805 is slidably connected to the inside of the limiting groove 807. A baffle 808 is fixedly installed on the surface of the first gear 803.

[0028] In this implementation scheme: the jack 4 is fixed by the bracket 7 and the support plate 6. The level of the support plate 6 is adjusted according to the level 802. The motor spindle is lifted by the jack 4. The height of the spindle can be quickly determined by the vertical scale 10. The center of the motor is adjusted to make the gap between the stator and the rotor uniform. A leveling component 8 is set up so that the horizontal center of the motor can be quickly adjusted by the level 802, avoiding the inability to control the gap between the stator and the rotor, which could cause damage to the motor insulation when the stator is removed. The level 802 can also be fixed by the first gear 803, the second gear 804 and the double-headed rack 806, which facilitates the disassembly and maintenance of the level 802 and prevents the level 802 from malfunctioning during long-term use, which would cause display errors and affect the core extraction operation.

[0029] Combining the above solutions:

[0030] Furthermore:

[0031] like Figures 1 to 4 As shown;

[0032] In an optional embodiment, to fix the level 802, there are two sets of first gears 803, which are symmetrically installed at both ends of the fixing groove 801.

[0033] In this embodiment, two sets of first gears 803 are provided and symmetrically installed at both ends of the fixing groove 801. This allows the baffles 808 on the surfaces of the two sets of first gears 803 to simultaneously fix both ends of the level 802, preventing the level 802 from falling out of the fixing groove 801 and causing damage.

[0034] Combining the above solutions:

[0035] Furthermore:

[0036] like Figures 3 to 4 As shown;

[0037] In an optional embodiment, to facilitate the rotation of the first gear 803, a rotating block 809 is fixedly mounted on the surface of the baffle 808 on which one set of first gears 803 is mounted.

[0038] In this embodiment, a rotating block 809 is installed on the surface of a baffle 808 mounted on the surface of one of the first gears 803, so as to facilitate the rotation of the first gear 803 and thus facilitate the fixation of the baffle 808 on the level 802.

[0039] Combining the above solutions:

[0040] Furthermore:

[0041] like Figures 3 to 4 As shown;

[0042] To facilitate the synchronous movement of the baffle 808, in an optional embodiment, one end of the double-ended rack 806 is meshed with a first gear 803 on which the baffle 808 is mounted, and the other end of the double-ended rack 806 is meshed with a second gear 804.

[0043] In this embodiment: one end of the double-ended rack 806 is meshed with the first gear 803 on which the baffle 808 is installed, and the other end of the double-ended rack 806 is meshed with the second gear 804. When the rotating block 809 is rotated, the rotating block 809 can drive one set of the first gear 803 to rotate. Since the first gear 803 is meshed with one end of the double-ended rack 806, it can drive the double-ended rack 806 to move. At the same time, the double-ended rack 806 can drive the second gear 804 meshed with its other end to rotate, thereby driving the other set of first gears 803 to rotate, so as to realize the synchronous movement of the baffles 808 on both sides of the fixed groove 801.

[0044] Combining the above solutions:

[0045] Furthermore:

[0046] like Figures 3 to 4 As shown;

[0047] In an optional embodiment, to drive another set of first gears 803 to rotate, the second gear 804 and one of the sets of first gears 803 are meshed together.

[0048] In this embodiment, the second gear 804 is meshed with another set of first gears 803. When the double-headed rack 806 moves, it can drive the second gear 804 to rotate. Since the second gear 804 and the first gear 803 are meshed, the second gear 804 can drive the first gear 803 to rotate.

[0049] Combining the above solutions:

[0050] Furthermore:

[0051] like Figures 3 to 4 As shown;

[0052] In order to limit the movement of the double-headed rack 806, in an optional embodiment, there are two sets of limiting grooves 807 and two sets of limiting blocks 805, and the two sets of limiting blocks 805 are slidably connected inside the two sets of limiting grooves 807 respectively.

[0053] In this embodiment, two sets of limiting blocks 805 and two sets of limiting grooves 807 are provided, and the two sets of limiting blocks 805 are slidably connected in the limiting grooves 807 respectively. When the double-headed rack 806 moves, the two sets of limiting blocks 805 can slide in the limiting grooves 807 respectively, avoiding excessive rotation of the rotating block 809, which would cause the double-headed rack 806 to move too much and fall off.

[0054] Combining the above solutions:

[0055] Furthermore:

[0056] like Figures 1 to 2 As shown;

[0057] In an optional embodiment, to protect the motor spindle, the bracket 7 is U-shaped and a rubber pad 9 is mounted on the top surface of the bracket 7.

[0058] In this embodiment: the bracket 7 is set as U-shaped, and a rubber pad 9 is installed on the U-shaped bracket 7 to protect the main shaft. The jack 4 is fixed by the U-shaped bracket 7 and the support plate 6. The level of the support plate 6 is adjusted according to the level instrument 802. The motor main shaft is lifted by the jack 4 to adjust the center of the motor.

[0059] Combining the above solutions:

[0060] Furthermore:

[0061] like Figures 1 to 2 As shown;

[0062] To quickly determine the height of the motor spindle, in an optional embodiment, a vertical scale 10 is mounted on the surface of the jack 4.

[0063] In this embodiment: A vertical scale 10 is installed on the surface of the jack 4. The height of the motor spindle can be quickly determined by the vertical scale 10, and the center of the motor can be adjusted to make the stator and rotor gap uniform.

[0064] Combining the above solutions:

[0065] Furthermore:

[0066] like Figures 3 to 4 As shown;

[0067] In an optional embodiment, a magnetic block 11 is fixedly installed on the inner wall of the fixing groove 801 to pre-fix the level 802, and the level 802 is pre-fixed inside the fixing groove 801 by the magnetic block 11.

[0068] In this embodiment, a magnetic block 11 is installed inside the fixing groove 801 to pre-install the level 802, preventing the level 802 from falling off when the baffle 808 is moved.

[0069] Working principle: In use, a U-shaped bracket 7 is set up, and a rubber pad 9 is installed on the U-shaped bracket 7 to protect the motor spindle. The jack 4 is fixed by the U-shaped bracket 7 and the support plate 6. According to the indication of the level 802, the level of the support plate 6 can be adjusted by the threaded rod 5. The motor spindle is lifted by the jack 4, and the height of the spindle can be quickly determined by the vertical scale 10. The center of the motor is adjusted to make the stator and rotor gap uniform. When it is necessary to disassemble and maintain the level 802, the rotating block 809 is manually rotated. The rotating block 809 will drive one set of first gears 803 to rotate, and the first gears will rotate simultaneously. Wheel 803 drives double-headed rack 806 to move. At this time, limit block 805 slides in limit groove 807. Double-headed rack 806 then drives the second gear 804 at its other end to rotate. The second gear 804 can then drive another set of first gears 803 to rotate. At this time, both sets of first gears 803 rotate. Simultaneously, the rotation of the first gears 803 drives the baffle 808 to rotate until the fixing groove 801 is opened. At this time, pull the level 802 to separate the level 802 from the magnetic block 11, so that it can be completely removed from the fixing groove 801 and then replaced.

Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
