Abstract
Description
Technical Field
[0001] This invention relates to the field of railway locomotive maintenance equipment technology, and in particular to a traction motor cleaning device. Background Technology
[0002] With the continuous upgrading and development of electrified railway technology, locomotive operating speeds and service frequencies have been significantly improved. This has also placed higher demands on the operational reliability and maintenance quality of core locomotive components. Traction motors, as the core and critical component for locomotive power output, operate under complex and harsh conditions such as rain, snow, sandstorms, and oil contamination. Various pollutants easily accumulate and adhere to hidden critical locations such as stator winding gaps and rotor surfaces. This not only accelerates the aging and wear of internal components and shortens the traction motor's lifespan but also directly threatens locomotive operating safety. Therefore, cleaning and maintenance of traction motors has become a crucial aspect of ensuring locomotive operational safety.
[0003] Currently, traction motor cleaning is typically done manually, relying on forklifts for loading, unloading, and transferring the motors. This method is not only inefficient and costly in terms of labor, making it unsuitable for large-scale cleaning operations, but also susceptible to variations in cleaning quality due to differences in human skill levels, leading to over-cleaning or contaminant residue, and making it difficult to guarantee consistent cleaning quality.
[0004] Therefore, there is an urgent need to develop a traction motor cleaning device to solve the above-mentioned technical problems. Summary of the Invention
[0005] The purpose of this invention is to provide a traction motor cleaning device that helps ensure consistent cleaning quality, reduces labor costs, and improves cleaning efficiency.
[0006] Based on the above concept, the technical solution adopted by this invention is as follows: This invention provides a traction motor cleaning device, including a feeding mechanism, a cleaning mechanism, and a discharging mechanism. The feeding mechanism is disposed at the feeding end of the cleaning mechanism and is used to transport the motor to be cleaned to the cleaning mechanism. The discharging mechanism is disposed at the discharging end of the cleaning mechanism and is used to receive and transport the cleaned motor. The cleaning mechanism includes a cleaning fluid storage tank and a working component. The working component includes a rotary table and a multi-axis robotic arm. The rotary table is used to support the motor to be cleaned and can rotate in a vertical direction to drive the motor to be cleaned to rotate together. The multi-axis robotic arm is connected to the cleaning fluid storage tank and has a liquid outlet. The cleaning fluid in the cleaning fluid storage tank can flow out from the liquid outlet to clean the motor to be cleaned.
[0007] In some embodiments, the working assembly further includes an isolation chamber, a first lifting door, and a second lifting door. The first lifting door is movably disposed in the isolation chamber and can switch the feed inlet of the isolation chamber between an open state and a closed state. The second lifting door is movably disposed in the isolation chamber and can switch the discharge outlet of the isolation chamber between an open state and a closed state. The rotary table and the multi-axis robotic arm are both disposed inside the isolation chamber.
[0008] In some embodiments, the working assembly further includes a top sprayer disposed on the inner top wall of the isolation chamber, the spray nozzle of the top sprayer facing the rotary table, the top sprayer being connected to the cleaning fluid storage tank, and the cleaning fluid in the cleaning fluid storage tank being able to flow out from the spray nozzle of the top sprayer to clean the motor to be cleaned on the rotary table.
[0009] In some embodiments, multiple working components are provided, arranged in a straight line along the direction from the feed end to the discharge end of the cleaning mechanism. The discharge port of the upstream isolation chamber is aligned with the feed port of the downstream adjacent isolation chamber and can communicate with each other. The motor to be cleaned can be sequentially transported to the rotating table in each working component for step-by-step cleaning.
[0010] In some embodiments, the isolation chamber has a transparent viewing window on its side wall and a condenser on its top, the condenser being connected to the interior of the isolation chamber.
[0011] In some embodiments, the feeding mechanism includes a first support frame and a first transmission component. The first transmission component includes a first bearing body, a first moving component, and a buffer platform. The first bearing body is movably connected to the first support frame in a vertical direction to vertically rise and fall between a first position and a second position. The bearing surface of the first bearing body at the first position is at the same height as the bearing surface of the rotary table in the vertical direction. The second position is below the first position. The bearing surface of the first bearing body at the second position is at the same height as the bearing surface of the buffer platform in the vertical direction. The buffer platform is used to support the motor to be cleaned and can transfer the motor to be cleaned to the first bearing body at the second position. The first moving component is movably disposed on the first bearing body and can abut against the bottom of the motor to be cleaned. When the first bearing body is at the first position, the movement of the first moving component relative to the first bearing body can drive the motor to be cleaned from the first bearing body to the rotary table.
[0012] In some embodiments, the first transmission member further includes a stop member and a pressing member. The stop member is movably disposed at one end of the first support body near the cleaning mechanism and can extend or retract relative to the first support body. When the stop member extends relative to the first support body, the motor to be cleaned can stop against the stop member. The pressing member is movably disposed on the first support body and can extend or retract relative to the first support body. When the pressing member extends relative to the first support body, the pressing member presses against the bottom of the motor to be cleaned.
[0013] In some embodiments, the first support frame is further equipped with two sets of position sensors, one set of which is set to the first position and is used to sense and detect the first support body being raised and lowered to the first position; the other set of which is set to the second position and is used to sense and detect the first support body being raised and lowered to the second position.
[0014] In some embodiments, a visual recognition device is also installed on the first support frame. The visual recognition device is used to identify and collect the model information of the motor to be cleaned before entering the cleaning mechanism, and transmit the model information of the motor to be cleaned to the control system. The control system can call the corresponding cleaning program according to the model information of the motor to be cleaned and apply it to the working component.
[0015] In some embodiments, the discharge mechanism includes a second support frame and a second transmission component. The second transmission component includes a second bearing body and a second moving component. The second bearing body is movably connected to the second support frame in the vertical direction. The second moving component is movably disposed on the second bearing body and can abut against the bottom of the cleaned motor. When the bearing surface of the second bearing body and the bearing surface of the rotary table are at the same height in the vertical direction, the movement of the second moving component relative to the second bearing body can drive the cleaned motor to move from the rotary table to the second bearing body.
[0016] The beneficial effects of this invention are: The traction motor cleaning equipment provided by this invention uses a rotary table to rotate the motor to be cleaned, thereby changing the cleaning surface. At the same time, a multi-axis robotic arm can flexibly align and clean from multiple angles. The combination of these two features enables comprehensive cleaning of the motor, allowing for precise removal of contaminants from exposed surfaces and hidden corners. This effectively avoids over-cleaning or contaminant residue problems caused by individual differences in manual operation, ensuring consistent cleaning quality. Furthermore, this traction motor cleaning equipment integrates automated production line operations for feeding, cleaning, and discharging, which not only reduces labor costs but also improves cleaning efficiency, meeting the needs of batch cleaning operations.

Furthermore, the terms "first," "second," and "third," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0026] Embodiments of the present invention are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.
[0027] like Figures 1-9 As shown, this embodiment provides a traction motor cleaning device, including a feeding mechanism 100, a cleaning mechanism 200, and a discharging mechanism 300. The feeding mechanism 100 is disposed at the feeding end of the cleaning mechanism 200 and is used to transport the motor to be cleaned to the cleaning mechanism 200. The discharging mechanism 300 is disposed at the discharging end of the cleaning mechanism 200 and is used to receive and transport the cleaned motor.
[0028] The cleaning mechanism 200 includes a cleaning fluid storage tank 1 and a working component 2. The working component 2 includes a rotary table 21 and a multi-axis robotic arm 22. The rotary table 21 is used to carry the motor to be cleaned. The rotary table 21 can rotate in the vertical direction to drive the motor to be cleaned to rotate together. The multi-axis robotic arm 22 is connected to the cleaning fluid storage tank 1 and has a liquid outlet. The cleaning fluid in the cleaning fluid storage tank 1 can flow out from the liquid outlet to clean the motor to be cleaned.
[0029] In practice, the motor to be cleaned is fed to the rotary table 21 of the cleaning mechanism 200 via the feeding mechanism 100. Then, the rotary table 21 and the multi-axis robotic arm 22 are started, causing the rotary table 21 to rotate vertically to drive the motor to be cleaned to rotate synchronously. At the same time, the multi-axis robotic arm 22, which has multiple degrees of freedom adjustment, flexibly adjusts its posture and working position according to the preset cleaning path, so that the liquid outlet of the multi-axis robotic arm 22 can achieve real-time dynamic alignment with the part of the motor to be cleaned. The liquid outlet sprays the cleaning liquid in the cleaning liquid storage tank 1 at an appropriate pressure. With the synergistic effect of the rotation of the motor to be cleaned, the contaminants on the part to be cleaned are efficiently flushed away. After cleaning is completed, the rotary table 21 stops rotating, and the unloading mechanism 300 receives the cleaned motor and transports it to the next process.
[0030] The traction motor cleaning equipment provided in this embodiment can rotate the motor to be cleaned by means of a rotary table 21 to change the cleaning surface, while the multi-axis robotic arm 22 can achieve flexible positioning and cleaning at multiple angles. The two work together to complete the all-round cleaning of the motor to be cleaned, and can accurately remove dirt from the exposed surface and hidden dead corners of the motor. This effectively avoids the problem of over-cleaning or residual contaminants caused by individual differences in manual operation, which helps to ensure the consistency of cleaning quality. In addition, the traction motor cleaning equipment integrates automated production line operation of feeding, cleaning and discharging, which not only reduces labor input costs, but also helps to improve cleaning efficiency and meet the needs of batch cleaning operations.
[0031] Optionally, the multi-axis robotic arm 22 may include, but is not limited to, being configured as a six-axis robot.
[0032] like Figures 1-4 As shown, in some embodiments, the working component 2 further includes an isolation chamber 23, a first lifting door 24 and a second lifting door 25. The first lifting door 24 is movably disposed in the isolation chamber 23 and can switch the feed inlet of the isolation chamber 23 between an open state and a closed state. The second lifting door 25 is movably disposed in the isolation chamber 23 and can switch the discharge outlet of the isolation chamber 23 between an open state and a closed state. The rotary table 21 and the multi-axis robotic arm 22 are both disposed inside the isolation chamber 23.
[0033] Specifically, when the feeding mechanism 100 delivers the motor to be cleaned to the cleaning mechanism 200, the first lifting door 24 rises vertically, opening the inlet of the isolation chamber 23 to allow the motor to pass through. After the motor moves to the rotary table 21 via the inlet of the isolation chamber 23, the first lifting door 24 descends vertically to close the inlet of the isolation chamber 23. Simultaneously, the second lifting door 25 is also positioned to close the outlet of the isolation chamber 23. Subsequently, the rotary table 21 and the multi-axis robotic arm 22 are activated, allowing the motor to be cleaned inside the closed isolation chamber 23. After cleaning, the second lifting door 25 rises vertically, opening the outlet of the isolation chamber 23, allowing the cleaned motor to be transferred to the discharge mechanism 300 via the outlet of the isolation chamber 23.
[0034] With this setup, the isolation chamber 23, the first lifting door 24, and the second lifting door 25 can form a closed cleaning space, allowing the cleaning of the motor to be cleaned to be completed in an isolated environment. This effectively prevents the cleaning fluid from splashing or evaporating and causing physical harm to the on-site operators, while also preventing the cleaning fluid from splashing or evaporating and polluting the surrounding working environment. This balances the safety of personnel and the cleanliness of the site, and helps to further improve the practicality and safety of the traction motor cleaning equipment.
[0035] Further optional, such as Figures 1-4As shown, a transparent window is provided on the side wall of the isolation chamber 23, and a condenser 3 is provided on the top of the isolation chamber 23, which is connected to the interior of the isolation chamber 23. With this configuration, the operator can observe the cleaning operation and motor cleaning status inside the isolation chamber 23 in real time through the transparent window. At the same time, the condenser 3 can eliminate the mist and steam generated during the cleaning operation, preventing the mist from obstructing the transparent window and affecting the field of vision.
[0036] like Figure 6 and Figure 7 As shown, in some embodiments, the working component 2 further includes a top spray member 26, which is disposed on the inner top wall of the isolation chamber 23. The spray nozzle of the top spray member 26 is disposed facing the rotary table 21. The top spray member 26 is connected to the cleaning fluid storage tank 1, and the cleaning fluid in the cleaning fluid storage tank 1 can flow out from the spray nozzle of the top spray member 26 to clean the motor to be cleaned on the rotary table 21.
[0037] For example, after the motor to be cleaned is transferred to the rotary table 21, the rotary table 21 and the top spray component 26 can be started at the same time, so that the motor to be cleaned rotates together with the rotary table 21 while being sprayed and cleaned by the top spray component 26. After the spray cleaning is completed, the top spray component 26 is turned off, and then the multi-axis robotic arm 22 is started to clean from multiple angles.
[0038] With this setup, the top spray unit 26 can spray and rinse the motor to be cleaned, which can remove most of the floating dust and attached oil stains on the surface of the motor in advance. Then, it can be used in conjunction with the multi-axis robotic arm 22 to perform multi-angle precise point cleaning, which helps to improve the comprehensiveness and overall quality of cleaning.
[0039] like Figures 1-5 As shown, in some embodiments, multiple working components 2 are provided. Along the direction from the feed end of the cleaning mechanism 200 to the discharge end of the cleaning mechanism 200, multiple working components 2 are arranged in a straight line. The discharge port of the upstream isolation chamber 23 is aligned with the feed port of the downstream adjacent isolation chamber 23 and can communicate with each other. The motor to be cleaned can be sequentially transported to the rotary table 21 in each working component 2 for step-by-step cleaning.
[0040] like Figures 1-5As shown, taking an example with two working components 2, the motor to be cleaned, conveyed by the feeding mechanism 100, first enters the first isolation chamber 23 through the inlet for the first stage of cleaning. After the first stage of cleaning, the motor is removed from the outlet of the first isolation chamber 23 and then enters the second isolation chamber 23 through the inlet for the second stage of cleaning. After the second stage of cleaning, the cleaned motor is removed from the outlet of the second isolation chamber 23 and subsequently transported by the discharge mechanism 300. Of course, in other embodiments, three or four working components 2 can also be provided, depending on the actual situation.
[0041] With this setup, the motor to be cleaned can enter each level of the working components 2 sequentially to complete the cleaning process step by step. In practical applications, the cleaning process at each level can be reasonably allocated according to the degree of contamination of the motor to be cleaned, avoiding the problem of excessive load and incomplete cleaning in a single cleaning cycle, which is conducive to further improving the cleaning quality.
[0042] Optionally, two adjacent isolation chambers 23 are interconnected, and the connection between the two adjacent isolation chambers 23 can share the same side wall. Taking two operating components 2 as an example, each operating component 2 includes an isolation chamber 23, a first lifting door 24 located at the inlet of the isolation chamber 23, and a second lifting door 25 located at the outlet of the isolation chamber 23. If the connection between the two adjacent isolation chambers 23 shares the same side wall, the outlet of the upstream isolation chamber 23 and the inlet of the downstream isolation chamber 23 can be merged into a single passageway. In this way, only one lifting door needs to be installed at this passageway to achieve communication or isolation between the two adjacent isolation chambers 23. Figure 3 and Figure 4 As shown, it can be understood that in two adjacent isolation chambers 23, the second lifting door 25 at the discharge port of the upstream isolation chamber 23 is the same as the first lifting door 24 at the inlet of the downstream isolation chamber 23.
[0043] like Figure 2 As shown, in some embodiments, the cleaning fluid storage tank 1 includes a clean water tank 11 and a cleaning agent tank 12. The multi-axis robotic arm 22 and the top spray component 26 can be independently connected to the clean water tank 11 and the cleaning agent tank 12, respectively. In this way, the clean water and the cleaning agent each form an independent conveying path, and the supply mode can be flexibly switched according to the cleaning process requirements. It can supply clean water alone or supply clean water and cleaning agent mixed together.
[0044] Taking the two-stage cleaning process of the motor as an example, the first stage can use a mixture of water and cleaning agent for overall cleaning, while the second stage can use pure water for rinsing. Alternatively, both stages can use a mixture of water and cleaning agent, but the cleaning can be performed in stages, targeting different parts of the motor. This allows for greater flexibility in process adjustments and a wider range of applicable scenarios.
[0045] like Figure 8 As shown, in some embodiments, the feeding mechanism 100 includes a first support frame 4 and a first transmission component 5. The first transmission component 5 includes a first bearing body 51, a first moving component 52, and a buffer platform 53. The first bearing body 51 is movably connected to the first support frame 4 in the vertical direction so that it can vertically rise and fall between a first position and a second position. The bearing surface of the first bearing body 51 in the first position is at the same height as the bearing surface of the rotary table 21 in the vertical direction. The second position is below the first position. The bearing surface of the first bearing body 51 in the second position is at the same height as the bearing surface of the buffer platform 53 in the vertical direction. The buffer platform 53 is used to support the motor to be cleaned and can transfer the motor to be cleaned to the first bearing body 51 in the second position. The first moving component 52 is movably disposed on the first bearing body 51 and can abut against the bottom of the motor to be cleaned. When the first bearing body 51 is in the first position, the movement of the first moving component 52 relative to the first bearing body 51 can drive the motor to be cleaned from the first bearing body 51 to the rotary table 21.
[0046] In practice, the first supporting body 51 is first vertically raised and lowered to the second position, and the motor to be cleaned temporarily stored in the buffer platform 53 is transferred to the first supporting body 51. Then, the first supporting body 51 carrying the motor to be cleaned is vertically moved to the first position, and then the first moving part 52 is activated to transfer the motor to be cleaned onto the rotary table 21.
[0047] With this setup, the feeding mechanism 100 can achieve an orderly connection between low-level buffer receiving and high-level precise feeding of the motor to be cleaned. The transfer process is stable and controllable, eliminating the need for manual lifting and alignment, effectively reducing labor intensity, and preventing collision damage to the motor during transfer.
[0048] The first moving part 52 includes, but is not limited to, a conveying roller. When the conveying roller rotates, it can drive the motor to be cleaned on it to move. When the conveying roller is stationary, the motor to be cleaned on it is also stationary at the current position.
[0049] Furthermore, conveyor rollers can also be installed on the bearing surface of the buffer platform 53. Through the cooperation of the conveyor rollers on the bearing surface of the buffer platform 53 with the first moving part 52, the motor to be cleaned on the buffer platform 53 can be transferred to the first bearing body 51. In addition, a transition bearing platform with conveyor rollers can also be installed between the first bearing body 51 and the rotary table 21. Conveyor rollers can also be installed on the bearing surface of the rotary table 21. A transition bearing platform with conveyor rollers can also be added between the rotary table 21 and the second bearing body 81 of the subsequent discharge mechanism 300 to form a smooth and continuous conveying path, ensuring continuous and reliable material loading, unloading and station flow processes.
[0050] like Figure 8 As shown, in some embodiments, the first transmission member 5 further includes a stop member 54 and a pressing member 55. The stop member 54 is movably disposed at one end of the first supporting body 51 near the cleaning mechanism 200 and can extend or retract relative to the first supporting body 51. When the stop member 54 extends relative to the first supporting body 51, the motor to be cleaned can be stopped by the stop member 54. The pressing member 55 is movably disposed on the first supporting body 51 and can extend or retract relative to the first supporting body 51. When the pressing member 55 extends relative to the first supporting body 51, the pressing member 55 presses against the bottom of the motor to be cleaned.
[0051] After the first supporting body 51 is vertically raised and lowered to the second position, before the motor to be cleaned, temporarily stored on the buffer platform 53, is transferred to the first supporting body 51, the stop member 54 extends relative to the first supporting body 51. Thus, when the motor to be cleaned is transferred from the buffer platform 53 to the first supporting body 51, the extended stop member 54 can stop the motor, preventing excessive movement. After the motor to be cleaned is stopped by the stop member 54, it indicates that the motor has been transferred to the correct position. At this time, the conveying action of the first moving member 52 is stopped, and the pressing member 55 extends relative to the first supporting body 51 to press against the bottom of the motor to be cleaned, forming a reliable clamping and limiting position, preventing the motor to be cleaned from shifting or tipping over during the subsequent vertical raising and lowering of the first supporting body 51. After the stop member 54 and the pressing member 55 have completed their limiting, the first carrier body 51 carrying the motor to be cleaned can be raised to the first position. When it is necessary to transfer the motor to be cleaned from the first carrier body 51 to the rotary table 21, the stop member 54 and the pressing member 55 are controlled to retract to release the limiting.
[0052] like Figure 8 As shown, in some embodiments, the first support frame 4 is also equipped with two sets of position sensors 6. One set of position sensors 6 is set to the first position and is used to sense and detect the first support body 51 rising and falling to the first position. The other set of position sensors 6 is set to the second position and is used to sense and detect the first support body 51 rising and falling to the second position.
[0053] With this setup, the two sets of position sensors 6 can accurately detect the position status of the first supporting body 51 in real time and promptly feed back the position signal, making it easy for the equipment to automatically control start and stop based on the position signal, thus avoiding excessive lifting of the first supporting body 51.
[0054] In some embodiments, a visual recognition device (not shown in the figure) is also installed on the first support frame 4. The visual recognition device is used to identify and collect the model information of the motor to be cleaned before entering the cleaning mechanism 200, and transmit the model information of the motor to be cleaned to the control system. The control system can call the corresponding cleaning program according to the model information of the motor to be cleaned and apply it to the operation component 2.
[0055] By adding a visual recognition device, the model parameters of the motor to be cleaned can be automatically identified and the information uploaded to the control system in real time. The control system automatically matches and calls up a dedicated cleaning program based on the motor model, enabling the operating component 2 to adapt to the cleaning conditions of different traction motor models. This allows the traction motor cleaning equipment to be adapted to the cleaning operations of motors of various specifications, improving the equipment's intelligence and versatility.
[0056] like Figure 9 As shown, in some embodiments, the discharge mechanism 300 includes a second support frame 7 and a second transmission component 8. The second transmission component 8 includes a second bearing body 81 and a second moving component 82. The second bearing body 81 is movably connected to the second support frame 7 in the vertical direction. The second moving component 82 is movably disposed on the second bearing body 81 and can abut against the bottom of the cleaned motor. When the bearing surface of the second bearing body 81 and the bearing surface of the rotary table 21 are at the same height in the vertical direction, the movement of the second moving component 82 relative to the second bearing body 81 can drive the cleaned motor to move from the rotary table 21 to the second bearing body 81.
[0057] For example, the second supporting body 81 can be adjusted vertically between the third position and the fourth position. The third position is where the bearing surface of the second supporting body 81 is flush with the bearing surface of the rotary table 21, which is convenient for receiving the cleaned motor. The fourth position is located below the third position and is a low-position discharge position. When the second supporting body 81 is lowered to the fourth position, it is convenient to remove the cleaned motor on the second supporting body 81 from the cleaning equipment and adapt it to subsequent transfer operations.
[0058] With this setup, the discharge mechanism 300 can smoothly receive and transfer the cleaned motor without the need for manual lifting, which helps reduce the intensity of manual labor and avoids damage to the cleaned motor from bumps.
[0059] Optionally, such as Figure 9As shown, two sets of position sensors 6 are installed on the second support frame 7. One set of position sensors 6 is set to the third position and is used to sense and detect the second support body 81 rising and falling to the third position. The other set of position sensors 6 is set to the fourth position and is used to sense and detect the second support body 81 rising and falling to the fourth position.
