Technical Field

[0002] Lubrication management of port machinery is an important part of port machinery equipment management, one of the main contents of improving and consolidating the good condition of port machinery equipment, and an indispensable link in the port production process. While modern equipment achieves high productivity, the wear of parts is also quite large. Good equipment lubrication can ensure the normal operation of port machinery equipment, prevent accidents, extend the service life of equipment, and reduce energy consumption. Lubricating oil is commonly used in the lubrication system of mechanical transmission parts, hydraulic transmission and engines. At present, gear transmission and bearing room are important components of mechanical equipment. The power of tire container gantry cranes and most forklifts is diesel engines. Many parts are rubbing at high speed or under heavy load. If the friction parts are not properly lubricated, dry friction will occur between metal and metal. The force generated by this friction is very large, which not only consumes a lot of power, but also the heat generated will melt the metal on the friction surface in a very short time, and even cause the parts to get stuck. Therefore, lubrication is essential.

[0003] At present, the lubrication schemes of major ports at home and abroad include manual lubrication and centralized lubrication. First, the quality and efficiency of manual replenishment are restricted by factors such as the technical proficiency and mood of the personnel, which is easy to cause replenishment omissions.

[0029] Embodiment 1

[0030] As Figure 1-7 shown, an intelligent flow control and distribution device for a lubrication system includes the following modules:

[0031] Positioning module, used to position the positioning spool 12, including a valve body 1 fixed on the base, the positioning spool 12 of the valve body 1 is in transmission connection with a first driving motor 3, and a first detection switch 2 is provided on the first driving motor 3;

[0032] Distribution module, used to control the distribution spool 11, including the distribution spool 11 of the valve body 1 is in transmission connection with a second driving motor 5, and a second detection switch 6 is provided on the second driving motor 5;

[0033] Detection module, used to detect the amount of grease entering the valve body 1, including a flow sensor 7 provided on the valve body 1;

[0034] Control module, connected to the positioning module, distribution module and detection module, used to realize the control and distribution of the flow rate according to a preset program. The control module includes a flow controller 4. The first detection switch 2, the second detection switch 6 and the flow sensor 7 are all electrically connected to the flow controller 4, and are used to transmit the detection signals of each part to the flow controller 4.

[0035] In this embodiment, the control module is connected to the positioning module, distribution module and detection module. Through the coordinated action of each module, the lubrication area is reasonably subdivided, and the flow rate of the lubricating grease is accurately controlled and distributed, ensuring that the machine or equipment can obtain appropriate lubrication during operation, and improving the efficiency and service life of the equipment.

[0036] As Figure 5 shown, the intelligent centralized lubrication system in this embodiment conducts system partitioned intelligent control application and research, abandons the oil supply method of distributing the long-distance main oil circuit to each branch oil circuit, and divides all lubrication points into several small local lubrication areas according to the distribution of oil injection points in each area according to the principle of centralized proximity. Each lubrication area is provided with an independent oil storage and oil supply device and sensors such as pressure, temperature and flow rate, becoming an independent area lubrication unit. The lubrication system is provided with a PLC central processor, which collects all the information transmitted by each area lubrication unit, and after program analysis and processing, intelligently sends various execution instructions to each area lubrication unit according to the user settings, realizing the automatic interactive intelligent operation of the whole machine lubrication system.

[0037] Principle: As Figure 1-4As shown in the figure, connect the interface of the main oil pipe to the oil inlet joint 9 of the valve body 1, so that the oil inlet joint 9 is interconnected with the main oil pipe. The intelligent flow control distributor and the main controller use serial 485 bus communication technology for data communication. When receiving the refueling command for a certain lubrication point of the host, the flow controller 4 energizes the first drive motor 3 and the second drive motor 5 to drive the distribution valve core 11 and the positioning valve core 12. At this time, the first detection switch 2 and the second detection switch 6 detect the distribution valve core 11 and the positioning valve core 12. The oil supply piston 13 reciprocates to continuously press a fixed amount of lubricating oil into the bearing. Since the stroke of the oil supply piston 13 is constant, the oil supply is quantitative. Because a magnetic steel is inlaid on the piston head, the flow sensor 7 can isolate and detect the number of piston movements. For example, Figure 6 The figure shows the actual appearance of the intelligent distributor. Each time it operates, it emits a pulse signal. The flow controller 4 controls the opening and closing of the valve body 1 according to the preset flow rate, realizing the flow control of grease. Figure 7 The figure shows the appearance of a suitable intelligent flow control distributor. The grease automatically circulates and refuels through this lubrication point according to the preset oil volume and interval time without manual intervention. If there is a refueling failure, the controller automatically sends the fault information to the host, and the host touch screen displays the fault information.

[0038] For example Figure 1-2 As shown in the figure, the intelligent distributor adopted in this embodiment is composed of a flow controller 4, a flow sensor 7, a valve body 1, two drive motors, two detection switches, etc. It mainly executes the instructions transmitted by the main control system and controls the oil supply volume of the pipeline.

[0039] For example Figure 3-4 As shown in the figure, the valve body 1 is internally designed with an oil passage. The front end of the valve body 1 is the grease inlet, and the grease inlet is connected to the internal oil passage of the valve body 1. The front end of the valve body 1 is threadedly connected with a grease inlet joint. The side end of the valve body 1 is provided with 4 grease outlets, and the grease outlets are connected to the internal oil passage of the valve body 1. The side end of the valve body 1 is threadedly connected with a grease outlet joint, and the outlet joint is connected to the external pipeline. The second drive motor is threadedly connected to the shaft of the valve body 1, and the motor is driven by a 24V power supply to control the 4 oil outlets inside the valve body. Among them, the second detection switch will determine whether the oil outlet is consistent with the set program. When the program is inconsistent, it will feedback a fault signal to the system, and regulate the grease to flow out from the 1-4th oil outlets as needed.

[0040] In the preferred solution, a power module is also provided, including arranging a terminal block 8 on the base, and the terminal block 8 is connected to an external power supply;

[0041] Among them, the flow controller 4, the first drive motor 3, and the second drive motor 5 are all connected to the terminal block 8.

[0042] In this embodiment, the terminal block 8 transmits power to the flow controller and the drive motor through cables, signal lines or other electrical connection means to ensure the stability and adaptability of the power supply to meet the power requirements of each component of the system.

[0043] In a preferred solution, the control module is connected to the positioning module to implement the positioning function, which specifically includes: the flow controller 4 controls the first drive motor 3, and the first drive motor 3 drives the positioning valve core 12 to communicate the positioning valve core 12 with the oil passage inside the valve body 1.

[0044] The power supply module provides power to each electric drive and controller in the system. The terminal block 8 transmits the power of the external power supply to the flow controller 4 and the drive motors (the first drive motor 3 and the second drive motor 5) to ensure normal operation and coordinated operation.

[0045] In a preferred solution, the detection module detects the amount of grease entering the valve body 1, which specifically includes: the flow sensor 7 detects and calculates the grease amount data flowing into the valve body 1 and transmits the grease amount data to the flow controller 4, and the flow controller 4 performs statistical summarization.

[0046] In this embodiment, the flow sensor 7 realizes the real-time monitoring and measurement of the amount of grease entering the valve body 1. The flow controller 4 makes a judgment according to the preset flow rate and controls the opening and closing of the valve body 1, realizing the flow control of grease, ensuring that the lubrication system can provide an appropriate amount of lubricating grease according to actual needs, thereby optimizing the performance and lifespan of the equipment.

[0047] In a preferred solution, the control module is connected to the distribution module to implement the distribution function, which specifically includes: according to the current control signal, the flow controller 4 controls the second drive motor 5, and the second drive motor 5 drives the valve body positioning valve core 12 to communicate the distribution valve core 11 with the oil passage inside the positioning valve core 12.

[0048] In this embodiment, the oil passage inside the distribution valve core 11 is controlled by the movement of the positioning valve core 12, thereby realizing the distribution of grease. According to the instruction of the flow controller 4, the distribution valve core 11 can adjust its opening and closing state to ensure the correct grease flow direction and distribution.

[0049] Function implementation process:

[0050] 1) Control signal generation: The external main device generates a control signal.

[0051] 2) Motor drive: The first drive motor 3 receives the control signal sent by the flow controller 4.

[0052] 3) Valve body positioning: The first drive motor 3 adjusts the position of the valve body positioning valve core 12 according to the control signal.

[0053] 4) When the valve body positions the spool 12 to rotate, the oil passages inside the distribution spool 11 and the positioning spool 12 are made to communicate or separate, and the flow sensor 7 controls the distribution of grease. This ensures that the lubrication system can accurately control and distribute grease according to real-time requirements, guaranteeing the lubrication effect of each part of the equipment, thereby enhancing the operation efficiency and lifespan of the equipment.

[0054] In a preferred solution, in the distribution module, the distribution spool 11 has multiple oil outlets, and according to the corresponding control signal of the flow controller 4, it controls the grease to pass through the corresponding oil outlets of the distribution spool 11.

[0055] In this embodiment, there are 4 oil outlets, and each oil outlet can be connected to different lubrication points. The on-off state and grease flow rate of each oil outlet can be independently controlled to meet the lubrication requirements of different parts. Precise grease distribution not only improves the lubrication effect but also reduces grease waste and enhances the overall efficiency of the system.

[0056] The flow controller 4 generates corresponding control signals according to the real-time requirements and monitoring data of the system, controls the opening and closing states and grease flow rates of different oil outlets of the distribution spool 11. The grease enters the distribution spool 11 from the valve body 1 and flows to different lubrication points according to the opened oil outlets.

[0057] In a preferred solution, the detection signals of each part are transmitted to the flow controller 4, including:

[0058] The position of the distribution spool 11 is detected by the second detection switch 6 on the second drive motor 5, and the detection signal is transmitted to the flow controller 4; the position of the positioning spool 12 is detected by the first detection switch 2 on the first drive motor 3, and the detection signal is transmitted to the flow controller 4.

[0059] In this embodiment, the first detection switch 2 is used to monitor the position of the positioning spool 12, and the second detection switch 6 is used to monitor the position of the distribution spool 11. When the position of the spool changes, a detection signal is generated and transmitted to the flow controller 4 for real-time evaluation, thereby adjusting the control signal to ensure the accuracy of grease distribution and flow direction. By monitoring the spool position, the system can maintain stable grease distribution at any time, reducing the risk of failure; the flow controller 4 can make dynamic adjustments according to the detection signal, improving the efficiency and reliability of the entire lubrication system, thereby enhancing the intelligence level of the lubrication system and ensuring the efficient operation and long-term reliability of the equipment.

[0060] In a preferred solution, it further includes a feedback module, which is used to, when the oil outlet signal received by the second detection switch 6 is inconsistent with the preset program, feedback to the flow controller 4 and perform relevant processing.

[0061] In this embodiment, the feedback module monitors the oil outlet signal received by the second detection switch 6, compares the received signal with the preset program or the desired grease flow rate / distribution mode. If they are inconsistent, the feedback module will issue a warning or an abnormal signal to ensure the normal operation of the system.

[0062] In the preferred solution, the flow controller 4 is also provided with a manual / automatic switching button and a control switch for the device.

[0063] This embodiment uses a 24V power supply. The flow controller 4 is driven by the 24V power supply. The flow controller 4 is provided with two buttons for manual / automatic and start / stop. Press and hold the manual / automatic button for 3 - 5S to complete the switching between the manual mode and the automatic mode. In the manual mode, quickly press the button twice to select the oil outlets No. 1 - 4. Select the automatic button, and the lubrication system will enter the automatic operation state. Select the manual button, determine the oil outlet, click the start / stop button to start the lubrication system. When the oil outlet pipeline is filled with grease or the lubrication point is filled with grease, click the start / stop button again to close the lubrication system. In the manual mode, the operator should not leave.

[0064] During use, as Figure 5 shown, for the overall lubrication system, the flow controller 4 energizes the first drive motor 3 and the second drive motor 5 to drive the distribution valve core 11 and the positioning valve core 12. At this time, the first detection switch 2 and the second detection switch 6 detect the distribution valve core 11 and the positioning valve core 12. The oil supply piston 13 reciprocates to continuously press a fixed amount of lubricating oil into the bearing; the flow controller 4 controls the opening and closing of the valve body 1 according to the preset flow rate, realizing the flow control of grease. The grease automatically circulates and refuels at the lubrication point according to the preset oil volume and interval time without manual intervention. If there is a refueling fault, the controller automatically sends the fault information to the host computer, and the host computer touch screen displays the fault information.

The protection scope of the present invention should be the technical solutions recorded in the claims, including the equivalent replacement solutions of the technical features in the technical solutions recorded in the claims.
