Description

Technical Field

[0001] The utility model relates to the technical field of pump couplings, in particular to a quick-detachable vertical pump coupling. Background Art

[0002] A vertical pump coupling is a key mechanical component used to connect a vertical pump's drive motor to the pump shaft. Its primary function is to transmit torque while allowing for a certain degree of axial, radial, or angular misalignment. It can also absorb vibration and shock when necessary, protecting the equipment from damage.

[0003] Chinese patent publication number CN215927882U, publication date 20220301, discloses a coupling for a vertical pump, including a pump coupling arranged on the pump shaft, a motor coupling arranged on the motor shaft, and a locking mechanism for fixing the motor coupling to the motor shaft; the pump coupling is locked on the pump shaft by a round nut and a lock washer; the locking mechanism includes a shaft head locking assembly arranged on the motor shaft head and a side locking assembly arranged on the side of the motor shaft; the pump coupling and the motor coupling are fixedly connected by hinged hole bolts.

[0004] The various accessories of the above-mentioned existing vertical pump couplings use an overfitting method to realize the transmission of the pump shaft and the motor shaft. During the specific implementation process, due to the small space between the pump shaft and the motor shaft, it is often necessary to shift or remove the motor before using auxiliary tools to remove the coupling, which is inconvenient. Therefore, it is urgent to propose a corresponding quick-release vertical pump coupling to solve the above problems. Utility Model Content

[0005] The purpose of the utility model is to solve the above problems and to propose a quick-detachable vertical pump coupling.

[0006] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0007] A quick-release vertical pump coupling comprises a motor shaft, a pump shaft, a pump-end coupling and a motor-end coupling. The pump-end coupling and the motor-end coupling are fixedly connected to the pump shaft and the motor shaft respectively. A steel claw is inserted into the side of the pump-end coupling away from the pump shaft, and an intermediate section is fixedly connected between the steel claw and the motor-end coupling. The outer wall of the curved end of the pump-end coupling is integrated with an elastic block and a limiting component for limiting the elastic block.

[0008] Preferably, the outer wall of the arc-shaped end of the pump-end coupling is fixedly connected to a fulcrum, and the elastic block is clamped on the outer wall of the fulcrum.

[0009] Preferably, the limiting assembly includes a protective cover, which is fixedly connected to the pump end coupling by screws, and the inner surface wall of the protective cover abuts against the outer surface wall of the elastic block.

[0010] Preferably, the inner surface wall of the pump end coupling is fixedly connected to a pressure plate, and the pump shaft is fixedly connected to the pressure plate via a hexagonal bolt.

[0011] Preferably, a taper fit is adopted between the outer wall of the pump shaft and the inner wall of the pump end coupling.

[0012] Preferably, the cross section of the middle section is an H-shaped structure, and the motor end coupling and the steel claw are fixedly connected to the vertical end of the middle section through a fastening rod.

[0013] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0014] 1. In the present application, the pump-end coupling and the pump shaft are fixed with hexagonal bolts, and at the same time, a taper is used between the pump shaft and the inner surface wall of the pump-end coupling to ensure stable transmission of the pump-end coupling and the pump shaft while preventing the hexagonal bolts from loosening easily due to being coaxial with the pump shaft. Subsequently, multiple sets of fastening rods are separated to separate the motor-end coupling and the pump-end coupling with the middle section and the steel claws. At this time, an operating space appears between the motor-end coupling and the pump-end coupling. The operator can quickly separate the motor shaft and the pump shaft based on this operating space, thereby ensuring the stability of the pump coupling and the convenience of disassembly and assembly of the pump coupling.

[0015] 2. In this application, the steel claw is inserted into the pump end coupling, and then the middle section is fixed by the tightening rod. The elastic block is combined with the fulcrum on the pump end coupling, and finally the protective cover is fixed to the pump end coupling. The protective cover is mounted on the outside of multiple groups of elastic blocks to prevent the elastic blocks from falling. When the elastic blocks need to be replaced later, it is only necessary to separate the protective cover, thereby ensuring the convenience of replacing the elastic blocks, thereby further improving the convenience of using the pump coupling.

[0021] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] See also Figure 1-3 , the utility model provides a technical solution:

[0023] A quick-release vertical pump coupling includes a motor shaft 6, a pump shaft 7, a pump-end coupling 1, and a motor-end coupling 5. The pump-end coupling 1 and the motor-end coupling 5 are fixedly connected to the pump shaft 7 and the motor shaft 6, respectively. A steel claw 3 is inserted into the side of the pump-end coupling 1 away from the pump shaft 7, and an intermediate section 4 is fixedly connected between the steel claw 3 and the motor-end coupling 5. The outer wall of the curved end of the pump-end coupling 1 is integrated with an elastic block 12 and a limiting assembly for limiting the elastic block 12.

[0024] The pump-end coupling 1 and the pump shaft 7 are fixed with hexagonal bolts 9. At the same time, a taper is used between the pump shaft 7 and the inner surface wall of the pump-end coupling 1 to ensure stable transmission of the pump-end coupling 1 and the pump shaft 7 while preventing the hexagonal bolts 9 from loosening easily due to being coaxial with the pump shaft 7. Subsequently, multiple groups of fastening rods 10 are separated to separate the motor-end coupling 5 and the pump-end coupling 1 with the middle section 4 and the steel claws 3. At this time, an operating space appears between the motor-end coupling 5 and the pump-end coupling 1. The operator can quickly separate the motor shaft 6 and the pump shaft 7 from the motor-end coupling 5 and the pump-end coupling 1 based on this operating space, thereby ensuring the stability of the pump coupling and the convenience of disassembly and assembly of the pump coupling.

[0025] Specifically, such as Figure 2 and Figure 3 As shown, the outer wall of the arc-shaped end of the pump-end coupling 1 is fixedly connected with a fulcrum 11, and the elastic block 12 is clamped on the outer wall of the fulcrum 11. The limiting assembly includes a protective cover 2, which is fixedly connected to the pump-end coupling 1 by screws, and the inner wall of the protective cover 2 is in contact with the outer wall of the elastic block 12. The steel claw 3 is inserted into the pump-end coupling 1, and then the middle section 4 is fixed by the fastening rod 10. After the elastic block 12 is combined with the fulcrum 11 on the pump-end coupling 1, the protective cover 2 is finally fixed to the pump-end coupling 1. The protective cover 2 is mounted on the outside of multiple groups of elastic blocks 12 to prevent the elastic blocks 12 from falling. When the elastic blocks 12 need to be replaced later, it is only necessary to separate the protective cover 2, thereby ensuring the convenience of replacing the elastic blocks 12, thereby further improving the convenience of using the pump coupling.

[0026] Specifically, such as Figure 2 and Figure 3 As shown, the inner wall of the pump-end coupling 1 is fixedly connected to the pressure plate 8, and the pump shaft 7 is fixedly connected to the pressure plate 8 by a hexagonal bolt 9. The outer wall of the pump shaft 7 and the inner wall of the pump-end coupling 1 are tapered, and the pump-end coupling 1 and the pump shaft 7 are fixed by hexagonal bolts 9. At the same time, a taper is adopted between the pump shaft 7 and the inner wall of the pump-end coupling 1 to ensure stable transmission of the pump-end coupling 1 and the pump shaft 7 while preventing the hexagonal bolts 9 from being easily loosened due to being coaxial with the pump shaft 7. The cross-section of the middle section 4 is an H-shaped structure. The motor-end coupling 5 and the steel claw 3 are fixedly connected to the vertical end of the middle section 4 by a fastening rod 10, which realizes the series connection of the motor-end coupling 5 and the steel claw 3. The motor-end coupling 5 and the steel claw 3 can be separated from one side later.

[0027] Working principle: The pump-end coupling 1 and the pump shaft 7 are fixed with hexagonal bolts 9. At the same time, a taper is used between the pump shaft 7 and the inner wall of the pump-end coupling 1 to ensure the stable transmission of the pump-end coupling 1 and the pump shaft 7 while preventing the hexagonal bolts 9 from being easily loosened due to being coaxial with the pump shaft 7. Subsequently, multiple sets of fastening rods 10 are separated to separate the motor-end coupling 5 and the pump-end coupling 1 with the middle section 4 and the steel claw 3. At this time, an operating space appears between the motor-end coupling 5 and the pump-end coupling 1. The operator can use this operating space to quickly separate the motor-end coupling 5 and the pump-end coupling 1 to separate the motor shaft 6 and the pump shaft 7. , thereby ensuring the stability of the use of the pump coupling and the convenience of disassembly and assembly of the pump coupling, inserting the steel claw 3 into the pump end coupling 1, and then completing the fixation of the middle section 4 through the fastening rod 10, and combining the elastic block 12 with the fulcrum 11 on the pump end coupling 1, and finally fixing the protective cover 2 to the pump end coupling 1, and the protective cover 2 is mounted on the outside of multiple groups of elastic blocks 12 to prevent the elastic blocks 12 from falling. When the elastic blocks 12 need to be replaced later, it is only necessary to separate the protective cover 2, thereby ensuring the convenience of replacing the elastic blocks 12, thereby further improving the convenience of using the pump coupling.
