Description

Technical Field

[0001] This utility model relates to the field of refining and chemical equipment, specifically to a transfer device for transporting water pumps from the air cooler platform of a refining and chemical plant. Background Technology

[0002] In the industrial sector, especially in the various units of oil refining and chemical enterprises, a large number of cooling devices are needed in the process flow to meet the temperature requirements of the medium in the pipeline, so as to ensure the qualification rate and production output of refining and chemical products.

[0003] Evaporative air coolers, also known as closed-circuit cooling towers, are high-efficiency and energy-saving cooling devices that integrate water cooling and air cooling, as well as heat and mass transfer processes, combining the advantages of both. They are widely used in industries such as metallurgy, petrochemicals, and chemicals. The working process involves a vertical circulating water pump delivering cooling water from a tank to a spray system located above the process tube bundle. The spray system sprays the cooling water downwards onto the tube bundle surface, forming a thin water film. Simultaneously, an air-cooling fan above draws in air, causing it to flow upwards across the tilted tube bundle, accelerating the airflow and rapidly evaporating the thin water film, thus cooling the tube bundle. To achieve this, two impeller-type vertical water pump motors are attached to both sides of each evaporative air cooler. The two motors operate in a standby mode, continuously supplying circulating water from the tank to the upper part of the evaporative air cooler.

[0004] The platforms where water pump motors are mounted are often located at high altitudes, with only a single steel plate at the bottom. This results in significant vibration during operation, and the motor's proximity to the water tank exposes it to a humid environment, leading to a relatively high failure rate. Due to its unique location, maintenance work is mostly performed on-site. Space is limited on the air cooler platform, with the vertical water pump motor attached near the water tank. The inlet and outlet circulating water pipes, steel structural frames, and other components are intertwined, leaving very little actual working space for maintenance personnel.

[0005] Currently, maintenance personnel rely solely on one method: using a gantry crane for hoisting. This method is extremely difficult to implement. To accommodate the confined space and numerous pipes in the work environment, the gantry crane often needs to be moved back and forth between pipes, posing a significant safety hazard for mobile gantry cranes. Even after placement, the vertical water pump motor is too close to the water tank casing, making vertical hoisting impossible. The operation is unstable and often requires multiple people to work together. In conclusion, improvements are urgently needed for the maintenance, relocation, and replacement of water pumps on the air cooler platform of the refining and chemical plant. Utility Model Content

[0044] To address the limitations of maintaining, relocating, and replacing the water pump motor 700 on the air cooler platform of a refining and chemical plant, a water pump transfer device for the air cooler platform has been invented. This invention incorporates external support rods 21, designed to fit the actual site environment of the air cooler platform. These rods can be moved vertically to both sides of the air cooler water pump, encircling the water tank at the bottom of both sides. This effectively avoids obstructions such as numerous inlet and outlet circulating water pipes, valves, and steel structural frames, shifting the operation direction to the larger space outside the water tank and completely overcoming the limitations of working in confined spaces. This invention adopts a modular design, allowing for direct assembly on-site according to the actual environment. Compared to traditional gantry cranes, it is more stable, easier to operate, and significantly enhances practicality. This invention is suitable for use in refining and chemical plants with numerous air-cooled platforms. The design includes a load-bearing frame 5, positioned high to ensure the verticality of the chain hoist during initial lifting. This prevents tilting and swaying during lifting. Furthermore, the motor can be moved horizontally inwards and outwards via a movable component without moving the entire unit, significantly enhancing operational safety. The integrated chassis 2 features a separately designed bearing groove C2, allowing the lifted water pump motor 700 to be stably lowered onto the chassis 2 for transfer and maintenance. This invention effectively avoids the drawbacks of previous methods.

After threading the main fixing bolt 6 through the main fixing hole K3 and connecting it to the main fixing groove C3, and threading the two secondary fixing bolts 7 to the secondary fixing holes K1, the assembly of the load-bearing component and the support component is completed.

[0054] The movable component includes a support block 8, a movable baffle 9, a movable baffle mounting bolt 100, a slide rod 200, a drag frame 300, an outer drag nut 400, and an inner drag nut 500. The support block 8 has a T-shaped structure. A flat rectangular fixed baffle 81 is provided at the left end of the support block 8, and the fixed baffle 81 is integral with the support block 8. A square lifting groove C4 is formed inward from the center of the upper end face of the main body of the support block 8. Two circular movable baffle mounting grooves C5 are provided at the right end of the support block 8, and the movable baffle mounting grooves C5 have internal threads. The movable baffle 9 has a flat rectangular structure, and its structure and dimensions are the same as those of the fixed baffle 81. Two circular movable baffle mounting holes K6 are provided on the end face of the movable baffle 9. Two movable baffle mounting bolts 100 are provided. Each movable baffle mounting bolt 100 has a common bolt-like structure and can be threaded into the movable baffle mounting groove C5. For example... Figure 5 As shown, the diameter and arrangement of the two movable baffle mounting slots C5 are the same as the diameter and arrangement of the two movable baffle mounting holes K6. The movable baffle 9 is connected to the bearing block 8 through the movable baffle mounting bolt 100 and the movable baffle mounting slot C5 threaded connection.

[0055] Two slide rods 200 are provided. The main body of each slide rod 200 is a long cylindrical structure with external threads on its outer side. A plug 201 is provided at the rear end of each slide rod 200. The plug 201 is a flat cylindrical structure and is integral with the slide rod 200. A circular drag frame mounting groove C6 with internal threads is provided at the center of the front end face of each slide rod 200. Two drag frames 300 are provided.

[0056] like Figure 10As shown, the dimensions of the main body of the support block 8 match the dimensions of the sliding hole K4; the length of the main body of the support block 8 is the same as the distance between the outer sides of the two sliding holes K4; after the support block 8 is inserted into the two sliding holes K4 at one end, the fixed baffle 81 is engaged with the outer side of one sliding hole K4, and the side end face of the movable baffle mounting groove C5 protrudes from the other sliding hole K4 and is flush with the end face of the sliding frame 52; Figure 11 As shown, after the movable baffle 9 is connected to the bearing block 8 via the movable baffle mounting bolt 100 and the movable baffle mounting groove C5 through a threaded connection, the bearing block 8 can slide within the sliding hole K4. Figure 12 As shown, the size of the bearing block insertion hole K7 matches the size of the main body of the bearing block 8, and the bearing block 8 can be inserted into the bearing block insertion hole K7.

[0057] like Figure 2 As shown, the diameter of the sliding rod insertion hole K2 is slightly larger than the diameter of the main body of the sliding rod 200 but smaller than the diameter of the plug 201. After the main bodies of the two sliding rods 200 are threadedly connected to the two outer drag nuts 400, the two sliding rods 200 are inserted into the two sliding rod insertion holes K2. The two inner drag nuts 500 are then threadedly connected to the main bodies of the two sliding rods 200. The positions of the two outer drag nuts 400 and the two inner drag nuts 500 are adjusted. The outer drag nuts 400 and the inner drag nuts 500 are respectively located on both sides of the fixed adjustment block 51. The outer drag nuts 400 and the inner drag nuts 500 are used to limit and pull the sliding rods 200. The inserted sliding rods 200 are then connected to the drag frame 300 via the sliding rod connector 301 and the threaded connection to the drag frame mounting groove C6. This completes the assembly of this utility model. It should be noted that, for example Figure 12 As shown, after the bearing block 8 is inserted into the sliding hole K4 on one side of the load-bearing frame 5, the two drag frames 300 are fitted onto the bearing block 8 through the bearing block insertion hole K7, and then the connection between the moving baffle 9 and the bearing block 8 is completed.

[0058] A water pump motor 700, connected to an impeller, is mounted on a water pump base. The water pump motor 700 is installed adjacent to the air cooler water tank 600. Inlet and outlet valves and pipelines are connected to both sides of the water pump motor 700 base. After the water pump motor 700 starts, it pumps water from the air cooler water tank 600 to the medium tube bundle housing 800, where the circulating water is sprayed onto the medium tube bundle to achieve a cooling effect. Due to the limited space, it is very difficult to install a conventional hoisting gantry crane nearby when the water pump motor 700 needs to be replaced, repaired, moved, or dismantled.

[0059] like Figure 13 As shown, when using this utility model, simply assemble it as described above, push it into the positive direction of the water pump motor 700, so that the outer support rod 21 spans both sides of the base of the water pump motor 700. At this time, brake the load-bearing universal wheel 1, adjust the outer drag nut 400 and the inner drag nut 500, and then manipulate the two slide rods 200 to drive the drag frame 300 to move the bearing block 8 to the top of the water pump motor 700. At this time, hang the lifting strap at the lifting slot C4, and use a conventional zipper to hang on the lifting strap to vertically lift the water pump motor 700. After the water pump motor 700 is lifted off the base, the inner drag nut 500 is unscrewed from the fixed adjustment block 51, and the outer drag nut 400 is brought close to the fixed adjustment block 51 and twisted, so that the slide rod 200 drives the drag frame 300 to drag the bearing block 8 outward, moving the water pump motor 700 to the outside. At this time, the zipper can be lowered, and the water pump motor 700 can be placed in the bearing groove C2 for maintenance; or the brake of the heavy-duty universal wheel 1 can be released, and the water pump motor 700 can be rotated.

[0060] During reinstallation, the same principle applies. After lifting the water pump motor 700 in the bearing groove C2, unscrew the outer drag nut 400 from the fixed adjustment block 51, and apply force to tighten the inner drag nut 500 close to the fixed adjustment block 51. This causes the slide rod 200 to drive the drag frame 300 to drag the bearing block 8 inward, moving the water pump motor 700 directly above the base. At this point, the water pump motor 700 can be lowered vertically to complete the reinstallation.

[0061] It should be noted that if the water pump motor 700 itself is not very heavy, the outer drag nut 400 and the inner drag nut 500 can be omitted during assembly, and the water pump motor 700 can be moved inward and outward by directly dragging the slide bar 200.

[0062] The above description is only an optional embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
