Description

Technical Field

[0001] This invention relates to the field of equipment maintenance technology, specifically to an integrated operation platform suitable for water pump maintenance. Background Technology

[0002] As a core fluid transport device in industrial production and municipal water supply, water pumps are prone to impeller wear, bearing failure and other malfunctions after long-term use, requiring regular maintenance. However, the current traditional decentralized maintenance model has many drawbacks.

[0003] Workpiece transfer relies on manual labor and simple tools, resulting in high labor intensity and a high risk of component damage due to collisions, thus extending maintenance cycles. Maintenance involves manual transfer between different workstations for processes such as casing disassembly, impeller separation, and heated installation, leading to poor process continuity and low efficiency. Bearing and impeller installation often uses oil bath heating, which results in uneven temperature distribution and oil leakage. Furthermore, residual oil from disassembling the pump casing can easily spread, polluting the environment and posing safety hazards.

[0004] The existing maintenance methods suffer from low efficiency, high component damage rates, and harsh working environments, necessitating an integrated maintenance platform to address these issues. Therefore, this paper proposes an integrated maintenance platform suitable for water pump repair. Summary of the Invention

[0005] The purpose of this invention is to provide an integrated operation platform suitable for water pump maintenance, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: an integrated operation platform suitable for water pump maintenance, comprising:

[0007] Two gantry frames, with a hanging rail installed between the two gantry frames, and a monorail hoist for transferring water pumps installed on the hanging rail;

[0008] A calibration component, installed below the gantry frame, is used to inspect the assembly quality of the impeller and bearing;

[0009] The mounting assembly is installed below the gantry frame and is used for heating and installing the impeller and bearing.

[0010] An impeller disassembly assembly is installed below the gantry frame and is used for disassembling the impeller.

[0011] An oil collection assembly is installed on one side of the gantry frame and is used to collect oil when the water pump housing is disassembled.

[0012] Preferably, the calibration component includes a calibration table, which is installed on one side of the gantry frame, and a placement groove for placing a water pump is provided on one side of the calibration table.

[0013] Preferably, the installation assembly includes a placement platform, the upper surface of which has a placement through hole for placing a water pump, a support frame is rotatably connected to one side of the upper surface of the placement platform, and a hydraulic cylinder is slidably connected to the support frame.

[0014] Preferably, a heating box for heating the bearings and impeller is installed below the placement platform, and the heating box adopts electromagnetic induction temperature control heating.

[0015] Preferably, the impeller disassembly assembly includes a placement frame and a hydraulic gripper. The placement frame has an arc-shaped groove for placing the water pump, and the hydraulic gripper is located on one side of the placement frame.

[0016] Preferably, the oil collection assembly includes a support platform, which is installed on one side of the gantry frame. An oil storage tank for collecting oil is installed below the support platform, and the upper surface of the support platform is uniformly provided with through holes to facilitate oil collection.

[0017] Preferably, the upper surface of the support platform is equipped with a barrier to prevent oil leakage.

[0018] Compared with existing technologies, the beneficial effects of this invention are as follows: The combination of a hanging rail between two gantry cranes and a monorail hoist enables mechanized transport of water pumps, replacing manual labor and simple tool handling. This reduces labor intensity, avoids component collision damage during transport, and shortens the maintenance cycle. The centralized layout of the calibration, installation, impeller disassembly, and oil collection components eliminates the need for manual workpiece transfer across workstations, significantly improving process continuity and maintenance efficiency. The electromagnetic induction temperature-controlled heating box overcomes the uneven temperature and contamination problems of traditional oil bath heating, ensuring the assembly quality of impellers and bearings. The arc-shaped groove of the impeller disassembly component, combined with hydraulic grippers, enables impeller disassembly, reducing component wear. The oil collection component, through barriers, through-hole guidance, and an oil storage tank, efficiently collects oil from the disassembly of the outer casing, preventing environmental and equipment pollution, improving the working environment, and achieving multiple benefits overall, including improved maintenance efficiency, reduced component damage rate, and optimized working environment.

[0023] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

[0024] Please see Figure 1-3 This invention provides a technical solution: an integrated work platform suitable for water pump maintenance, comprising two gantry frames 1. The two gantry frames 1 provide a stable support foundation for the entire work platform, ensuring the installation and operational stability of each work component. A hanging rail 7 is installed between the two gantry frames 1, laterally connecting the two gantry frames 1 to form a cross-sectional work channel. A monorail crane 2 for transferring water pumps is mounted on the hanging rail 7. The monorail crane 2 can move flexibly along the extension direction of the hanging rail 7, enabling the transfer of water pumps between different work areas of the platform, reducing manual handling and improving the continuity of the work process.

[0025] The calibration component 3 is installed in the lower area of ​​the gantry 1. This component can provide a stable placement and testing environment for manual inspection of impellers and bearings. The testing items include impeller dynamic balance, bearing coaxiality, and inspection of the installation quality of impellers and bearings.

[0026] Mounting component 4 is also located below the gantry 1. This component can heat the impeller and bearing, and assist in the assembly of the two after heating. By heating, the fit effect of the parts during assembly is optimized, the assembly difficulty is reduced, and structural damage to the parts caused by forced assembly is avoided.

[0027] The impeller disassembly assembly 5 is installed at the corresponding working position below the gantry frame 1. It is used to disassemble the impeller on the water pump that needs to be replaced or repaired. It can stably fix the water pump body and apply a uniform disassembly force to the impeller, ensuring that the impeller does not deform or get damaged during the disassembly process, thus ensuring the smooth progress of subsequent maintenance or replacement work.

[0028] The oil collection component 6 is installed on one side of the gantry frame 1. When the water pump housing is disassembled, it can collect and collect the oil that flows out during the disassembly process, preventing the oil from spreading to the work area, keeping the work environment clean, and avoiding the oil from polluting other components of the platform or the surrounding environment.

[0029] like Figure 1 and Figure 2 As shown: The calibration assembly 3 includes a calibration table 31, which is fixedly installed on one side of the gantry frame 1, forming a stable connection with the gantry frame 1. A placement groove 32 for placing a water pump is provided on one side of the calibration table 31, which can stably limit the water pump in the groove, providing stable conditions for accurate testing of the impeller and bearing assembly quality.

[0030] like Figure 1 and Figure 2 As shown: Mounting assembly 4 includes a placement platform 41. The upper surface of the placement platform 41 has a placement through-hole 42 for placing the water pump. The placement through-hole 42 can position the water pump body. A support frame 44 is rotatably connected to one side of the upper surface of the placement platform 41. The support frame 44 can be adjusted in angle around the rotation connection point to adapt to the operational needs of different assembly scenarios. A hydraulic cylinder 45 is slidably connected to the support frame 44. The hydraulic cylinder 45 can move along the extension direction of the support frame 44, adjusting its position to provide appropriate force for the assembly of the impeller and bearing, assisting in the precise docking and assembly of parts.

[0031] like Figure 1 and Figure 2 As shown: A heating box 43 for heating the bearing and impeller is installed below the placement platform 41. The heating box 43 adopts electromagnetic induction temperature control heating method and achieves 360-degree uniform heating through eddy current effect, completely eliminating the pollution and temperature unevenness problems of traditional oil bath heating.

[0032] like Figure 1 and Figure 2 As shown, the impeller disassembly assembly 5 includes a placement frame 52 and a hydraulic gripper 51. The placement frame 52 supports the water pump with the impeller to be disassembled, providing stable support for the disassembly operation. The placement frame 52 has an arc-shaped groove 53 for placing the water pump. The arc-shaped groove 53 is adapted to the shape of the water pump body to prevent the water pump from shifting during disassembly. The hydraulic gripper 51 is located on one side of the placement frame 52 and can adjust its clamping state according to the size and position of the impeller. It applies a stable and uniform clamping force to the impeller, achieving separation of the impeller from the water pump body and preventing the impeller from breaking or deforming during disassembly.

[0033] like Figure 1 and Figure 2As shown: The oil collection assembly 6 includes a support platform 61, which is installed on one side of the gantry 1 and is used to place the water pump whose casing is to be disassembled, providing a working platform for the casing disassembly operation. Below the support platform 61 is an oil storage tank 64 for collecting oil, capable of receiving oil flowing down from the support platform 61. The upper surface of the support platform 61 has evenly spaced through holes 62 to facilitate oil collection. The through holes 62 penetrate the upper and lower surfaces of the support platform 61, allowing oil generated during disassembly to flow smoothly into the oil storage tank 64 below, preventing oil accumulation on the surface of the support platform 61. A valve is installed below the oil storage tank 64.

[0034] like Figure 1 and Figure 2 As shown: The upper surface of the support platform 61 is equipped with a barrier 63 to prevent oil leakage. The barrier 63 is set along the edge of the support platform 61 to form a surrounding barrier structure, which can prevent the oil flowing during the disassembly process from crossing the edge of the support platform 61, ensuring that the oil can flow into the oil storage tank 64 through the through hole 62, further improving the integrity of oil collection, while keeping the work area clean.

[0035] Working principle: The water pump to be repaired is hoisted by a monorail crane 2. The monorail crane 2 can slide laterally along the hoisting rail 7 between the two gantry frames 1, accurately transferring the water pump to the corresponding repair station, such as the casing disassembly or impeller disassembly station. No manual handling is required, which reduces labor intensity and avoids damage to the water pump due to collision during transportation.

[0036] The water pump with the casing to be disassembled is placed on the support platform 61 of the oil collection assembly 6. The perimeter barrier 63 of the support platform 61 can prevent oil from overflowing during disassembly. The oil generated during the disassembly process seeps downwards along the evenly spaced through holes 62 on the surface of the support platform 61 and finally flows into the oil storage tank 64 below the support platform 61 for collection, keeping the working environment clean and preventing oil from contaminating other components.

[0037] After the outer casing is disassembled, the water pump body is moved onto the placement frame 52 of the impeller disassembly assembly 5. The arc-shaped groove 53 on the placement frame 52 is adapted to the shape of the water pump, which can stably limit the water pump and prevent displacement during disassembly. The hydraulic gripper 51 on one side of the placement frame 52 is activated. The hydraulic gripper 51 adjusts the clamping force according to the impeller size, applying a uniform and stable force to the impeller, realizing the non-destructive separation of the impeller from the water pump body, and ensuring the feasibility of subsequent maintenance or replacement of the impeller.

[0038] After maintenance, place the water pump body on the mounting platform 41 of the mounting assembly 4, and position the water pump through the mounting through-hole 42 on the platform 41. Start the heating box 43 below the platform 41. The heating box 43 uses electromagnetic induction temperature control to evenly heat the impeller and bearing. Then, adjust the angle of the support frame 44 rotatably connected to one side of the upper surface of the platform 41, and slide the hydraulic cylinder 45 on the support frame 44 to the appropriate position. Apply precise force through the hydraulic cylinder 45 to assist in the quick and non-destructive assembly of the impeller or bearing.

[0039] Finally, the water pump is moved to the calibration platform 31 of the calibration component 3. Then, the staff checks the impeller dynamic balance, bearing coaxiality and other indicators to determine whether the impeller and bearing assembly meets the maintenance standards and to ensure the quality of subsequent installation.

[0040] Although embodiments of the 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 invention, the scope of which is defined by the appended claims and their equivalents.
