Description

Technical Field

[0001] This utility model relates to the field of sewage treatment equipment technology, and more specifically, to a tooling for disassembling and assembling a booster pump with a cooling jacket. Background Technology

[0002] In wastewater treatment plants, lift pumps with cooling jackets are core equipment for maintaining wastewater transport and treatment processes. They are widely used in critical stages such as wastewater lifting and sludge return. The cooling jacket and pump body are typically connected with a high-strength sealant via interference fit or high-temperature cured sealant to withstand long-term wastewater corrosion and mechanical wear. However, this tight connection presents significant challenges to traditional disassembly methods: rough operations such as hammering and prying are not only inefficient, but the impact can easily deform the cooling jacket and scratch the sealing surface, leading to increased component scrap rates and soaring maintenance costs. Furthermore, these operations require multiple operators, pose a high risk of tool slippage, and create personal safety hazards, severely hindering the standardized implementation of maintenance work.

[0003] Existing disassembly techniques struggle to balance efficiency and safety, often resulting in prolonged equipment downtime due to lengthy disassembly times. This directly impacts the continuous operation of wastewater treatment systems and can even lead to environmental risks due to reduced treatment capacity. Although some general-purpose disassembly tools exist on the market, they lack designs adapted to the precision structure of the cooling jacket, making it impossible to achieve simultaneous multi-point force application and precise vertical guidance, and making it difficult to avoid off-center load damage. Therefore, to address the aforementioned technical issues, a tooling for disassembling and assembling a booster pump with a cooling jacket is proposed. Utility Model Content

Through the guiding positioning and steel cable winding structure, the power of the drive motor is converted into multi-point synchronous traction, so that the cooling jacket is vertically stressed and evenly detached from the pump body, avoiding damage from impact. At the same time, the detachable drive component and the pre-positioning snap-fit ​​design simplify the assembly process, reduce the operation intensity, and ensure the reusability of the equipment and the safety of maintenance, significantly improving the disassembly efficiency and reliability.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figures 1-4This utility model proposes a tooling for assembling and disassembling a lift pump with a cooling jacket, including a lift pump body 1, a cooling jacket body 2, and a mounting frame 3. A D-shaped buckle 4 is fixedly connected between the lift pump body 1 and the mounting frame 3. A fixing plate 5 is fixedly connected to the inner side of the mounting frame 3. A rotating rod 6 is rotatably connected to the inner side of the fixing plate 5. A winding component 7 is fixedly connected to the outer side of the rotating rod 6. A steel cable 8 is wound around the outer side of the winding component 7. A hook 9 is fixedly connected to the end of the steel cable 8. A hanging ring 10 is fixedly connected to the outer side of the cooling jacket body 2, and the hook 9 and the hanging ring 10 are hooked together. A guide mechanism is installed on the lower side of the fixing plate 5. The top of the rotating rod 6 protrudes from the upper surface of the mounting frame 3 and is fixedly connected to a fixing plate 13. A square groove 14 is opened on the upper side of the fixing plate 13. A fixing cylinder 15 is detachably connected to the upper side of the mounting frame 3. A drive mechanism is installed on the inner side of the fixing cylinder 15.

[0022] The booster pump body 1 and the cooling jacket body 2 are connected by a sealant. The booster pump body 1 is a heavy machine with a weight of up to 10 tons. This connection method can ensure that the two remain stable and sealed during operation to prevent sewage leakage. The external fixed connection of the mounting frame 3 is a lifting ring, which can be used to lift the entire mounting frame 3 with a crane to disassemble the cooling jacket.

[0023] The number of D-type buckles 4 is several sets arranged in a ring. The ring distribution of D-type buckles 4 makes the connection between the mounting bracket 3 and the booster pump body 1 more uniform and firm, improving the overall stability.

[0024] The guiding mechanism includes a through hole 11 and a guide cylinder 12. The through hole 11 is opened on the lower side of the fixed plate 5, and the guide cylinder 12 is fixedly connected to the lower side of the fixed plate 5. The number of through holes 11, guide cylinders 12 and hanging rings 10 are several sets and arranged in a ring. The axes of hanging rings 10, through holes 11 and guide cylinders 12 are all coincident. This coaxial design ensures that the steel cable 8 is subjected to vertical force during the lifting process, avoiding the cooling jacket body 2 from being stuck due to skew. The steel cable 8 passes through the inside of the through hole 11 and the guide cylinder 12, and wear-resistant plates are fixedly connected to the contact parts between the inside of the through hole 11 and the steel cable 8. The wear-resistant plates can effectively prevent the wear of the steel cable 8 during use and avoid the need to replace the steel cable 8 frequently.

[0025] A connecting block is fixedly connected to the bottom of the fixed cylinder 15, and a screw hole is opened on the upper side of the mounting bracket 3. A fixing bolt is threaded between the connecting block and the screw hole. The fixed cylinder 15 and the mounting bracket 3 are detachably connected by the fixing bolt. The bolt connection method facilitates the quick disassembly and assembly of the drive mechanism and improves the flexibility of tooling use.

[0026] The drive mechanism includes a drive motor 16, a rotating shaft 17, a mounting plate 18, and a locking block 19. The drive motor 16 is fixedly connected to the upper side of the fixed cylinder 15, the rotating shaft 17 is fixedly connected to the lower side of the drive motor 16, the mounting plate 18 is fixedly connected to the end of the rotating shaft 17, and the locking block 19 is fixedly connected to the lower side of the mounting plate 18. The locking block 19 matches the square groove 14. The matching design of the locking block 19 and the square groove 14 enables precise power transmission and ensures that the rotating rod 6 rotates smoothly. The drive motor 16 can be a high-torque, low-speed motor to assist in the disassembly of the cooling jacket body 2.

[0027] An elastic pad 20 is fixedly connected to the bottom of the fixing plate 5, and the elastic pad 20 is located directly above the cooling jacket body 2. The elastic pad 20 can prevent the cooling jacket body 2 from being damaged due to impact with the fixing plate 5 when it is disassembled.

[0028] The working principle of a tooling for disassembling and assembling a lift pump with a cooling jacket, based on an embodiment, is as follows: In actual applications at wastewater treatment plants, lift pumps with cooling jackets are subjected to long-term corrosion and mechanical vibration in wastewater environments. The cooling jacket body 2 and the lift pump body 1 are often connected with a high-strength connection via interference fit or high-temperature cured sealant. Traditional disassembly methods rely on hammering or prying, which can easily cause deformation of the cooling jacket, damage to the sealing surface, and safety hazards to personnel. This tooling addresses these issues by using modular design and synchronous lifting technology to achieve safe and efficient disassembly of the cooling jacket. Specifically, during disassembly, the operator first precisely aligns the guide cylinder 12 of the mounting bracket 3 with the hanging ring 10 on the outer wall of the cooling jacket. The mounting bracket 3 and the lift pump body 1 are quickly fixed using the circularly arranged D-shaped buckles 4. Then, the steel cable 8 extending from the winding component 7 is passed through the through hole 11 of the fixing plate 5, ensuring a reliable connection between the hook 9 and the hanging ring 10. The fixing plate 13 at the top of the rotating rod 6 is manually adjusted to pre-position the square groove 14 with the locking block 19 of the drive mechanism, thereby allowing the pump to disassemble. The fixed cylinder 15 is locked to the mounting bracket 3 with bolts, completing the power connection between the drive motor 16 and the rotating rod 6. Then, the mounting bracket 3 is lifted as a whole by the lifting ring for operation. After the motor is started, the rotating shaft 17 drives the locking block 19 to engage with the square groove 14, driving the rotating rod 6 to rotate at a uniform speed, so that the winding part 7 synchronously winds multiple steel cables 8. During this process, the vertical guiding system formed by the through hole 11 and the guide cylinder 12 effectively constrains the movement trajectory of the steel cables 8, ensuring that each hanging point of the cooling jacket is evenly loaded, avoiding scratches on the sealing surface or structural deformation caused by uneven loading. Compared with the traditional violent disassembly method, this tooling uses mechanical transmission and multi-point synchronous traction technology. Since the lifting pump body 1 is heavy machinery, the traction force can be controlled to achieve vertical and stable detachment of the cooling jacket, which not only protects the integrity of the equipment, but also significantly shortens the maintenance time. In addition, the drive mechanism adopts a detachable design. After disassembly, the tooling is compact in size, which is convenient for storage and transportation. It is suitable for the narrow working space of sewage treatment plants, providing a solution for ensuring production continuity and reducing maintenance costs.

[0029] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
