Description

Technical Field

[0001] This utility model relates to the field of lubrication equipment, and in particular to an intelligent monitoring and control oil pump, such as a grease pump. Background Technology

[0002] A grease pump (also known as a lubricating grease pump) is a grease injection device powered by compressed air. It uses the pump to generate high pressure for grease injection and is widely used in lubrication systems in machinery manufacturing, automotive industry, metallurgical equipment and other fields.

[0003] like Figure 1 As shown, a traditional grease pump typically includes a base, a lifting drive frame, a pneumatic pump, a suction pipe, a pressure plate, and a control system. The lifting drive frame generally consists of two columns and a crossbeam. The columns house a lifting device (such as a hydraulic cylinder or lead screw) that drives the crossbeam to move up and down. The pneumatic pump is mounted on the crossbeam, and its suction port is connected to the pressure plate via a suction pipe. The pressure plate is placed in a grease container (such as a 200-liter plastic bucket). The negative pressure generated by the pneumatic pump draws in the grease, which is then delivered to the grease dispenser or lubrication point via an outlet pipe.

[0004] However, existing grease pumps have many design limitations:

[0005] 1. In terms of liquid level monitoring, traditional equipment typically uses a simple mechanical trigger alarm system. For example, a pressure plate is installed on the side of the crossbeam; when the grease is depleted, the pressure plate contacts an alarm on the top of the controller. This method relies entirely on physical contact and is a passive monitoring system. Operators cannot know the remaining grease level in advance, which can easily lead to sudden interruptions in production and affect continuous operation efficiency. Furthermore, the phenomenon of dry pumping not only reduces the equipment's lifespan but can also damage pneumatic pump components, increasing maintenance costs and production losses.

[0006] 2. Regarding lifting, positioning, and sealing, existing equipment relies on manual observation and adjustment of the alignment between the pressure plate and the barrel opening. This often results in misalignment between the pressure plate and the barrel opening, leading to poor sealing, air intake, reduced oil extraction efficiency, and even pump damage. Furthermore, traditional pressure plate designs are simple, often planar, and do not match the shape of the barrel bottom, resulting in excessive grease residue and material waste. The suction pipe is easily compressed by external atmospheric pressure when the grease is drawn to the bottom, affecting flow stability. The pneumatic system has high energy consumption, high compressed air consumption, and lacks intelligent adjustment functions.

[0007] Therefore, a new technical solution needs to be researched to address the above problems. Utility Model Content

[0008] In view of this, the present invention addresses the deficiencies of the existing technology and its main purpose is to provide an intelligent monitoring and control oil pump that integrates intelligent liquid level monitoring to achieve active monitoring, and uses a through-beam photoelectric sensor to improve the situation of easy misalignment during centering, effectively solving the problems of passive liquid level monitoring, low positioning accuracy and poor oil suction efficiency in the existing technology.

[0009] To achieve the above objectives, the present invention adopts the following technical solution:

[0010] An intelligent monitoring and control oil pump includes a base, a lifting drive frame, a pneumatic pump, an oil suction pipe, a pressure plate, and a controller. The lifting drive frame includes two columns and a crossbeam. A first lifting device is provided inside the columns, which drives the crossbeam to rise and fall. The pneumatic pump is mounted on the crossbeam. The oil suction port of the pneumatic pump is connected to the oil suction pipe. The bottom of the oil suction pipe is connected to the pressure plate.

[0014] As a preferred embodiment, the pneumatic pump, the oil suction pipe, and the pressure plate are configured as a single component, the position of which on the crossbeam is adjustable. This component is also connected to an XY-axis automatic translation mechanism. The controller is configured to control the XY-axis automatic translation mechanism to automatically adjust the position of the component on the crossbeam based on the signal from the photoelectric sensor, so that the pressure plate is aligned with the center of the grease container opening.

[0015] As a preferred embodiment, the pressure plate has an inflatable sealing ring on its outer periphery at the bottom, and the controller has a sealing ring inflation switch. The controller is electrically connected to the sealing ring inflation switch to control the inflation of the sealing ring.

[0016] As a preferred embodiment, the bottom of the pressure plate is flat or curved, and a one-way valve is integrated inside the oil suction port of the pressure plate.

[0017] As a preferred embodiment, the pressure plate is equipped with an electromagnetic pressure relief valve, and the controller is electrically connected to the electromagnetic pressure relief valve to automatically control the pressure relief.

[0018] As a preferred embodiment, the pneumatic pump is equipped with an electro-proportional valve and a flow sensor on its air supply line, and the controller is electrically connected to the electro-proportional valve and the flow sensor to dynamically adjust the air pressure and flow rate.

[0019] As a preferred embodiment, the controller is an intelligent human-machine interface (HMI), which includes a touch screen and a data recording module. The data recording module is used to record the amount of oil injected, the working time, and the number of alarms.

[0020] As a preferred embodiment, a replaceable filter module is provided between the oil suction pipe and the oil outlet pipe.

[0021] Compared with the prior art, this utility model has significant advantages and beneficial effects. Specifically, as can be seen from the above technical solution, it mainly achieves active liquid level monitoring and corresponding multi-level early warning through a liquid level sensor and controller, avoiding production interruptions and equipment idling, and improving production efficiency and equipment reliability.

[0029] Please refer to Figures 2 to 5 As shown, it illustrates the specific structure of an embodiment of the present invention.

[0030] In the description of this utility model, it should be noted that the terms "upper", "lower", "left", "right", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0031] An intelligent monitoring and control oil pump, which is related to Figure 1 The basic structure of the existing oil pump shown is similar to that of the prior art. Based on this, improvements are made to enhance its intelligence and automation. It includes a base 11, a lifting drive frame 12, a pneumatic pump 14, an oil suction pipe 15, a pressure plate 16, and a controller 30. The lifting drive frame 12 includes two columns 121 and a crossbeam 122. The controller 30 is located on the side of one of the columns 121. A first lifting device 13 (such as an electric screw or hydraulic cylinder) is provided inside the column 121. The first lifting device 13 drives the crossbeam 122 to rise and fall. The pneumatic pump 14 is located on the crossbeam 122. The oil suction port of the pneumatic pump 14 is connected to the oil suction pipe 15. The bottom of the oil suction pipe 15 is connected to the pressure plate 16. The output end of the oil suction pipe 15 is also connected to an oil outlet pipe 17. A switch valve 171 is provided on the oil outlet pipe 17.

[0032] The pressure plate 16 integrates a liquid level sensor 161, which can be a capacitive liquid level sensor, an ultrasonic liquid level sensor, or a mechanical pressure plate switch. The controller 30 is electrically connected to the liquid level sensor and the pneumatic pump 14. The controller 30 is configured to implement multi-level early warning control based on the liquid level signal fed back by the liquid level sensor; providing a graded early warning mechanism to enable operators to respond promptly, reduce downtime, and optimize the production process. The multi-level early warning control includes issuing a first early warning signal when the liquid level is below a first threshold, issuing a second early warning signal when the liquid level is below a second threshold, and stopping the pneumatic pump 14 and issuing a third early warning signal when the liquid level is below a third threshold. Specifically: when the liquid level is below 30%, a yellow warning signal is displayed on the screen; when the liquid level is below 10%, the controller 30 triggers an alarm that flashes regularly and sounds a buzzer; when the liquid level is below 2%, the controller 30 automatically stops the pneumatic pump 14 and issues a continuous high-frequency alarm, thereby achieving intelligent liquid level monitoring and multi-level early warning, avoiding production interruptions and equipment idling, and improving production efficiency and equipment reliability.

[0033] A through-beam photoelectric sensor 1221 is provided at the bottom of the crossbeam 122. The controller 30 is electrically connected to the photoelectric sensor and is used to detect the position of the edge of the grease container opening. The controller 30 is connected to an indicator alarm unit 31. The controller 30 is configured to control the indicator alarm unit to give position indications based on the signals fed back by the photoelectric sensor, such as: sound alarms indicating "center", "move left", "move right", "move forward", "move backward", etc. Center indicates that the position is qualified, and other indications prompt the user to move the grease container.

[0034] In another embodiment, the pneumatic pump 14, the oil suction pipe 15, and the pressure plate 16 are configured as a single component, the position of which on the crossbeam 122 is adjustable. This component is also connected to an XY-axis automatic translation mechanism 123. The XY-axis automatic translation mechanism 123 is a complete module, comprising an X-axis automatic translation mechanism and a Y-axis automatic translation mechanism. The X-axis automatic translation mechanism is mounted on the crossbeam 122 and is driven by the X-axis automatic translation mechanism connected to the Y-axis automatic translation mechanism to generate X-axis translation. The Y-axis automatic translation mechanism is driven by the component to generate Y-axis translation. Both the X-axis and Y-axis automatic translation mechanisms can be driven by electric or pneumatic cylinders. The XY-axis automatic translation mechanism 123 is mounted on the crossbeam and electrically connected to the controller 30. It can drive the component to translate along the XY axes as needed. The controller 30 is configured to automatically adjust the position of the component on the crossbeam 122 based on signals from the photoelectric sensor, so that the pressure plate 16 is aligned with the center of the grease container's opening. This achieves automatic centering, reducing manual adjustment and improving positioning accuracy and operational efficiency. Furthermore, an auxiliary positioning mechanism 111 can be added to the base 11. After successful centering, the auxiliary positioning mechanism 111 elastically presses against the outer periphery of the grease container 20 for positioning.

[0035] Furthermore, an inflatable sealing ring 162 is provided on the outer periphery of the bottom of the pressure plate 16, and a sealing ring inflation switch (which can be integrated into the air blowing switch) is provided on the controller 30. The controller 30 is electrically connected to the sealing ring inflation switch to control the inflation of the sealing ring, which helps to ensure a good seal between the pressure plate 16 and the barrel opening, prevent air intake, and improve oil extraction efficiency and system stability.

[0036] Furthermore, the bottom of the pressure plate 16 is flat or curved, and a one-way valve is integrated inside the oil suction port of the pressure plate 16. This reduces residual oil waste, prevents grease backflow, and improves oil suction efficiency and material utilization.

[0037] Furthermore, the pressure plate 16 is equipped with an electromagnetic pressure relief valve, and the controller 30 is electrically connected to the electromagnetic pressure relief valve to automatically control pressure relief. The original pressure relief switch is replaced with an electromagnetic pressure relief valve, which is automatically controlled by the controller 30. It automatically opens to relieve pressure when work stops, ensuring safety; and automatically closes before work begins. This achieves automatic pressure relief control, improving safety and ease of operation, and reducing manual intervention.

[0038] Furthermore, the pneumatic pump 14 is equipped with an electric proportional valve and a flow sensor on its air supply line. The controller 30 is electrically connected to the electric proportional valve and the flow sensor. The controller 30 can dynamically adjust the air pressure and flow rate supplied to the pneumatic pump 14 according to the needs of the oil injector at the end of the oil outlet pipe 17 (through pressure feedback), thereby achieving on-demand energy supply. In this way, intelligent air circuit control is achieved, energy saving and consumption reduction are realized, and the air source is adjusted according to demand, which is conducive to reducing operating costs.

[0039] Furthermore, the controller 30 is an intelligent human-machine interface (HMI), which includes a touchscreen and a data recording module. The data recording module is used to record the amount of oil injected, working time, and number of alarms. This improves the user-friendliness of the interface, facilitates data management and remote monitoring, and enables digital equipment management.

[0040] Furthermore, a replaceable filter module is provided between the oil suction pipe 15 and the oil outlet pipe 17 to filter out tiny particulate impurities in the grease, protecting downstream equipment and extending the system's service life. Additionally, the oil suction pipe 15 is an oil-resistant composite hose with embedded steel wire, externally wrapped with a spiral steel armor layer. This ensures flexibility for easy lifting and positioning while preventing the grease from being crushed by atmospheric pressure when it reaches the bottom, ensuring stable flow and extending the pipeline's service life.

[0041] Furthermore, heavy-duty swivel casters are installed under the base 11, two of which are equipped with brakes, facilitating flexible movement and positioning of the equipment within the workshop and improving ease of use. The lifting area of ​​the lifting drive frame 12 is equipped with a safety protection device, which is a telescopic protective cover or a light grating sensor, providing reliable area protection to prevent operators' hands or other objects from entering the hazardous area, improving operational safety, preventing accidental injuries, and complying with industrial safety standards.

[0042] During operation, the operator pushes the equipment next to the new grease tank, roughly places the tank under the pressure plate 16, and presses the automatic operation button on the controller 30. The crossbeam 122 automatically descends, and the photoelectric sensor assists in centering, ensuring that the pressure plate 16 is precisely aligned with the tank opening. Once the pressure plate 16 is in position, the sealing ring automatically inflates and seals. The pneumatic pump 14 starts, beginning oil extraction. The controller 30 screen displays the liquid level and cumulative flow in real time. When the liquid level drops to the warning threshold, the system issues a warning of the corresponding level, allowing the operator to prepare a new grease tank in time. When the liquid level drops to the lowest threshold, the system automatically stops and sounds an alarm. When changing an empty tank, the operator presses the "Change Tank" button, the sealing ring automatically deflates, and the crossbeam 122 automatically rises to its highest position, completing the tank changing process.

[0043] Specifically, in combination Figure 2 and Figure 3 As shown, where, Figure 3 The improved intelligent workflow of the oil pump was demonstrated, featuring automation, intelligence, and high efficiency.

[0048] Phase 3: Intelligent Oil Extraction and Monitoring

[0049] Pneumatic pump starts → efficient oil pumping operation begins; real-time monitoring → continuously collects liquid level, flow rate, and pressure data; multi-level early warning → issues different levels of alarms based on liquid level status;

[0050] In Phase 4: Bucket Swapping Cycle

[0051] Emergency shutdown → Automatic protection when liquid level is too low; Drum changing operation → One-button drum changing process; Cyclic operation → Return to the feeding stage to continue operation.

[0052] The key design feature of this invention lies in its proactive liquid level monitoring and corresponding multi-level early warning system achieved through a liquid level sensor and controller. This prevents production interruptions and equipment idling, thereby improving production efficiency and equipment reliability. Furthermore, the inclusion of a through-beam photoelectric sensor at the bottom of the crossbeam for detecting the edge position of the grease tank opening enhances positioning accuracy.

[0053] Secondly, the alarm prompts and automatic centering both improve the centering and rotation efficiency of the grease tank; the inflatable sealing ring improves the sealing performance, which is conducive to improving the oil extraction efficiency; the bottom shape of the pressure plate and the integration of the one-way valve reduce residual oil waste, prevent grease backflow, and save material costs; intelligent air circuit control enables on-demand energy supply, effectively reducing energy consumption and operating costs.
