Description

Technical Field

[0002] Currently, in industrial production processes, speed reducers, as core transmission equipment for transmitting power and regulating speed, are crucial to the efficiency and reliability of the entire production line due to their stable operation. The lubricating oil inside the speed reducer plays a key role in reducing friction and wear, dissipating heat, and preventing corrosion. The condition of the lubricating oil (cleanliness, viscosity, and oil quantity) directly determines the speed reducer's transmission efficiency, operating temperature, noise level, and ultimate service life. Regular and standardized lubricating oil replacement and maintenance are fundamental to ensuring long-term trouble-free equipment operation and reducing the risk of unexpected downtime.

[0052] The following reference Figures 1 to 4This application describes an integrated gearbox lubricating oil replacement device according to embodiments of the present application.

[0053] See Figures 1 to 4 As shown, an embodiment of this application provides an integrated gear reducer lubricating oil replacement device. This integrated gear reducer lubricating oil replacement device includes: a working platform, a new oil filling system, and a waste oil recovery system. Both the new oil filling system and the waste oil recovery system are installed on the working platform. The waste oil recovery system includes at least a recovery container 12 and a recovery connector 17. The recovery connector 17 is connected to the recovery container 12 and is used to connect to the oil drain port of the gear reducer, so that the waste oil to be discharged in the gear reducer can flow into the recovery container 12 through the recovery connector 17. The new oil filling system includes at least an oil storage container 13, which stores new oil to be replaced. The oil storage container 13 can be connected to the oil inlet of the gear reducer to inject new oil into the gear reducer. As can be seen, the integrated reducer lubricating oil replacement equipment provided in this application recycles the waste oil of the reducer through a waste oil recycling system. The waste oil flows directly into the recycling container 12 through the recycling connector 17. Compared with the traditional method of manually discharging waste oil, this method is not only inefficient, but also prone to polluting the working environment. The emptying of waste oil is entirely based on the subjective judgment of the operator, which is prone to errors. Closing the drain port before the old oil is completely drained will result in old oil residue.

[0054] Specifically, the working platform includes: a mobile chassis 1, a wheel assembly 2, and a drive unit. The wheel assembly 2 is mounted on the mobile chassis 1, and the drive unit can be a motor mounted on the mobile chassis 1. The drive unit is connected to the wheel assembly 2 via an axle, thereby driving the wheel assembly 2 to move. This allows the integrated reducer lubrication oil replacement equipment to be moved to the working position to change or add oil to the designated reducer. The wheel assembly 2 specifically includes a combination of a steering wheel and a directional wheel with locking function. The tires of the steering wheel and the directional wheel are made of anti-skid rubber to meet the requirements of workshop application scenarios.

[0055] The mobile chassis 1 is equipped with a support platform 3 and an operating table 4. The support platform 3 and the operating table 4 are arranged adjacent to each other on the mobile chassis 1. The operator can stand on the support platform 3 to operate the operating table 4 or perform oil change operations. Preferably, the support platform 3 is located at the rear of the mobile platform, and the operating table 4 is semi-enclosed and surrounds the support platform 3 to ensure the safety of the operator when standing on the support platform 3. More preferably, the support platform 3 is hinged to the rear of the mobile chassis 1, and the upper surface of the support platform 3 is provided with an anti-slip surface after it is unfolded.

[0056] The control panel 4 includes a color touch screen 7 and a control cabinet 19. The touch screen 7 serves as a human-machine interface platform. The control cabinet 19 is mounted side-by-side with the control panel 4 on the mobile chassis 1. The control cabinet 19 houses a main control unit, which integrates a control system. Specifically, the control system can be a PLC, a common technology in the prior art. The touch screen 7 is electrically connected to the control cabinet 19 and can display the platform's operating status, oil change progress curve, equipment alarm information, and the human-machine interface. The control panel 4 also includes a start / stop control button 5, which is electrically connected to the drive unit. The start / stop control button 5 is used to control the movement or stop of the mobile chassis 1. The control panel 4 also includes a control device 6, which includes at least a direction lever, a brake device, and an accelerator pedal. The control device is connected to the wheel assembly 2 via a transmission mechanism. The control device 6 is used to control the direction and speed of travel of the mobile chassis 1. It should be noted that the connection between the control device 6 and the wheel assembly 2, as well as the control of the wheel assembly 2, are mature technologies used in existing electric vehicles, which are fully understood by those skilled in the art and will not be elaborated further here.

[0057] Preferably, a protective railing 8 is provided on the back of the touch screen 7.

[0058] Preferably, the bearing platform 3 is equipped with a weight detection unit, which can be a weight sensor. The weight detection unit is electrically connected to the main control unit, and the drive device is also electrically connected to the main control unit. The drive device is only allowed to be unlocked when the weight detection unit detects the effective load, forming a safety interlock mechanism to ensure the safety of operators and equipment.

[0059] Furthermore, this integrated reducer lubricating oil replacement equipment also includes a power supply, which can be a storage battery. The operating platform 4 has a closed shell with an internal storage space. The power supply is located in the storage space of the operating platform 4 and supplies power to the control cabinet 19, the drive device, and the electrical devices mentioned below. As the core power supply, the power supply supplies power to all platform equipment through a distributed cable network.

[0060] Furthermore, the recovery connector 17 is equipped with a heating device, which adopts an electric heating mode. The heating device heats the recovery connector 17, thereby improving the flow performance of the high-viscosity lubricating oil through electric heating.

[0061] Furthermore, the waste oil recycling system also includes a recycling hose and a recycling device 9, wherein the recycling device 9 can be a vacuum pump. The recycling device 9 acts on the recycling container 12, enabling a stable negative pressure environment to be formed inside the recycling container 12. Waste oil is extracted by negative pressure suction. One end of the recycling hose is connected to the recycling container 12, and a recycling connector 17 is located at the other end of the recycling hose. During operation, waste oil is drawn into the recycling container 12 through the recycling connector 17 and the recycling hose under the action of pressure difference. The heating device and the recycling device 9 are respectively connected to the power supply of the main control unit. The start and stop of the heating device and the recycling device 9 can be controlled by operating the touch screen 7, thereby controlling the temperature of the heating device and the duration of the waste oil recycling operation.

[0062] Furthermore, the waste oil recycling system also includes a pipeline storage device 15, which is mounted on the mobile chassis 1. The recycling hose is wound around the pipeline storage device 15, which can organize and store the recycling hose.

[0063] Furthermore, the new oil filling system also includes a filling device 10 and a delivery hose 14. The filling device 10 is preferably a frequency-controlled oil filling device commonly used in the prior art. The filling device 10 is connected to and communicates with the oil storage container 13. One end of the delivery hose 14 is connected to the filling device 10, and the other end of the delivery hose 14 is detachably connected to the oil inlet of the reducer. After the old oil in the reducer is drained, the filling device 10 is started, and the filling device 10 delivers the new oil from the oil storage container 13 to the reducer. In the initial stage, a high flow rate is used to quickly fill the reducer's oil chamber volume with new oil. In the final stage, the flow rate is switched to a low flow rate to finely adjust the final oil level, ensuring the accuracy of the new oil filling amount and preventing overfilling that could lead to overflow. Preferably, the end of the delivery hose 14 furthest from the filling device 10 is provided with a connecting joint 141 with a sealing structure to ensure no leakage during operation.

[0064] Preferably, the delivery hose 14 and the recovery hose are respectively equipped with overflow valves. When the pressure of the oil injection line and / or oil replacement line exceeds the preset limit, the corresponding overflow valve can be opened to release the pressure.

[0065] Furthermore, the new oil filling system also includes another pipeline storage device 15. The two pipeline storage devices 15 are spaced apart on the mobile chassis 1. The delivery hose 14 is wrapped around the other pipeline storage device 15, which can organize and store the delivery hose 14.

[0066] The pipe storage device 15 includes a support bracket 151, a winding motor 154, and a movable back plate 155. The support bracket 151 has a central shaft 153 and a base 152. The base 152 is bolted to the movable back plate 155. The central shaft 153 passes through the base 152 and is coaxial with it. The winding motor 154 is located on the side of the movable back plate 155 away from the support bracket 151. The shaft of the winding motor 154 is connected to the central shaft 153, allowing the support bracket 151 to rotate bidirectionally after the winding motor 154 is started, thus releasing and rewinding the delivery hose 14 / recovery hose. The winding motor 154 is electrically or communicatively connected to the main control unit, and its start / stop and winding speed can be controlled via a touch screen 7.

[0067] Preferably, each of the two pipe storage devices 15 is equipped with an overload protection device. The overload protection device can be an axial force sensor. The overload protection device is used to detect the torque of the rotating shaft or central shaft 153. The detection result of the overload protection device can reflect the winding resistance of the winding motor 154. The detection result can be transmitted to the main control unit and displayed on the touch screen 7, so that the operator can know it in time.

[0068] Furthermore, this integrated reducer lubricating oil replacement equipment also includes a purging system. The purging system includes a purging air tank, a purging connector 18, and a control valve. The purging air tank is located on the mobile chassis 1 and stores inert gas or clean air. The purging connector 18 is connected to the purging air tank, and the control valve is located on the purging connector 18. The purging connector 18 can be adapted to and detachably connected to the connection connector 141 of the delivery hose 14. After the oil change operation is completed, the delivery hose 14 is connected to the purging connector 18 so that the purging system can deliver gas to the delivery hose 14 to purge the delivery hose 14 and remove residual oil from the inner wall of the hose using airflow pressure.

[0069] Furthermore, this integrated reducer lubricating oil replacement device also includes a tool cabinet 11, which is mounted on a mobile chassis 1. The tool cabinet 11 includes multiple compartments, preferably of various sizes, to accommodate tools of different sizes. An oil storage container 13 is located in one compartment, and a recovery container 12 is located in another compartment. The tool cabinet 11 includes a work surface, and two pipe storage devices 15 are spaced apart on the work surface.

[0070] This integrated gearbox lubricating oil changing device also includes a tool rack 20, which is installed on one side wall panel of the tool cabinet 11. Preferably, the tool rack 20 is magnetically fixed to the tool cabinet 11. The tool rack 20 can hold commonly used tools for the oil change process, such as complete disassembly tool sets, oil stain cleaning kits, emergency sealing components, and spare quick connectors, as well as many other tools and accessories. All tool bags adopt a customized compartmentalized design for quick access. Preferably, each tool is equipped with a micro electronic tag, which can be an RFID tag.

[0071] Furthermore, this integrated reducer lubricating oil replacement equipment also includes an RFID reader 16, which is installed on the table of the tool cabinet 11. In the workshop, each reducer housing is fixedly equipped with an electronic tag, which stores the unique code and lubrication parameters of the equipment. Before changing the oil, the operator actively scans the electronic tag information on the reducer housing using the RFID reader 16 on the table, obtains the data, and transmits it to the main control unit. The unit can then match and set control parameters such as the suction time threshold, the filling flow curve, and the heating temperature range based on the relevant data.

[0072] Preferably, each tool on the tool rack 20 is equipped with an RFID reader 16. When working, after each tool is used, the RFID reader 16 at the corresponding position on the tool rack 20 scans it again to verify the tool. The RFID reader 16 is electrically or communicatively connected to the main control unit. The verification result can be transmitted to the main control unit and displayed on the touch screen 7 so that the staff can determine whether the tool has been returned to its place after use, reducing the probability of tool loss.

[0073] Furthermore, this integrated reducer lubricating oil replacement device also includes an emergency stop button, which is located on the control panel 4 and connected to the power supply. In case of an emergency, the power supply to the entire platform can be cut off with one click.

[0074] When this integrated gearbox lubricating oil replacement equipment is in operation, the operator stands on the extended support platform 3 to activate the system and drives the equipment to the target workstation via the operating device 6. The RFID reader 16 scans the electronic tag on the gearbox, and the touchscreen 7 loads the preset oil replacement parameters and generates a work confirmation interface. The pipeline storage device 15 releases the delivery hose 14. After opening the gearbox's oil inlet / outlet port using the appropriate disassembly tools from the tool cabinet 11 or tool rack 20, the operator inserts the hose connected to the recovery connector 17 into the drain port and starts the waste oil recovery process via the touchscreen 7. The main control unit activates the vacuum pump and heating functions. After the recovery device 9 runs for the set time or the gearbox's flow sensor sends a signal indicating oil evacuation, the equipment stops the drain process. The drain port is then sealed using a special tool. The new oil filling process is then performed. Following similar steps, the gearbox's oil inlet port is opened and the delivery hose 14 is inserted. The filling device 10 injects new lubricating oil into the gearbox. After the oil change process is completed, the purging connector 18 is installed at the head of the delivery hose 14 to purge any residual oil from the pipeline. The delivery hose 14 is then stored away by the pipeline storage device 15. The operator uses the RFID reader 16 to verify the integrity of the tools on the tool rack 20, and finally, the operator maneuvers the platform back into place.

[0075] In summary, the integrated gearbox lubricating oil replacement equipment provided in this application integrates the oil filling system, oil replacement system, and mobile platform into one unit. It requires only simple operation by staff. The waste oil recovery system and the new oil filling system are connected to the gearbox. The waste oil recovery system recovers waste oil, and the new oil filling system adds new oil to the gearbox. Compared to the traditional operation mode that relies entirely on manual oil replacement, this significantly improves oil replacement efficiency, reduces the workload of staff, effectively reduces the risk of waste oil pollution to the working environment, and avoids incomplete oil drainage due to human error, which affects the quality of oil replacement. This integrated gearbox lubricating oil replacement equipment significantly improves oil replacement efficiency and quality, maximizes the protection of the gearbox's core components, extends equipment lifespan, reduces lubrication management costs, and reduces the risk of production interruptions due to poor lubrication, providing a solid guarantee for the stable and efficient operation of the production line.
