Description

Technical Field

[0001] This invention relates to the field of distributor technology, and more particularly to a modular intelligent distributor. Background Technology

[0002] In current industrial intelligent centralized lubrication systems, traditional grease distributors are mostly integrated fixed valve body structures with a fixed number of branches at the factory. They cannot be flexibly expanded according to the increase or decrease of lubrication points on site or changes in equipment operating conditions, resulting in poor product versatility and high design and inventory costs.

[0003] Existing distributors have significant drawbacks: their integrated structure means that when a single branch is damaged, the entire unit must be disassembled and replaced, resulting in high maintenance costs and long downtime; most products lack independent single-line precise metering structures, making it difficult to accurately control the oil output and easily leading to problems such as insufficient lubrication wear or over-lubrication leakage; and they lack real-time pressure monitoring and abnormal warning functions, making it impossible to predict faults such as pipeline blockage, insufficient pressure, and media leakage in advance, thus reducing the service life of the equipment.

[0004] Existing modular products suffer from poor splicing and positioning accuracy, weak sealing performance, and are prone to oil leakage under high-pressure conditions, resulting in insufficient reliability. Currently, there is no integrated distributor that can achieve standardized modular splicing, independent single-channel electric control drive, precise quantitative oil dispensing, and online pressure monitoring throughout the entire process, making it difficult to meet the actual application needs of multi-point intelligent lubrication in engineering machinery, metallurgy, CNC machine tools, rail transportation, mining machinery, and other industries. Summary of the Invention

[0005] The main technical problem solved by this invention is to provide a modular intelligent allocator, thereby solving one or more of the problems in the prior art.

[0006] To solve the above-mentioned technical problems, the present invention adopts a technical solution as follows: a modular intelligent distributor, the innovation of which is that it includes multiple independent standardized valve block units, a drive coil module, a metering module, a pressure detection module, and a modular splicing and locking structure; The multiple standardized valve block units are detachably connected in series to form a modular base. Each valve block unit has an interconnected main oil supply channel and an independent branch oil outlet channel. The drive coil module is independently installed on each valve block unit and is used to independently control the opening and closing of the corresponding branch valve core; The metering module is mounted on the main oil supply channel and is used to precisely control the single oil output volume of each branch oil outlet channel. The pressure detection module is installed on the distributor and is used to collect pressure data at the end of the oil circuit in real time. Adjacent valve block units are assembled into a detachable and sealed combination through the modular splicing and locking structure.

[0007] In some implementations, the standardized valve block unit has standardized concave and convex positioning stops and centering pin holes on its side, and adjacent valve block units achieve precise alignment through the concave and convex positioning stops and positioning pins.

[0008] In some implementations, the modular splicing locking structure includes a through-type long locking bolt and an end nut, through which the through-type long locking bolt passes through all the series valve block units and cooperates with the end nut to complete the overall locking.

[0009] In some implementations, the mating contact surfaces of adjacent valve block units are provided with high-pressure sealing grooves, and annular high-pressure seals are installed in the high-pressure sealing grooves to achieve coaxial sealing of the oil circuit after splicing.

[0010] In some implementations, each valve block unit is independently configured with one or two sets of drive coil modules, and each set of drive coil modules controls a single branch valve core, so as to realize independent electronic control and time-sharing oil supply for each lubrication branch.

[0011] In some embodiments, the metering module includes a metering valve body, a quantitative metering chamber disposed within the metering valve body, and a precision metering valve core assembled within the quantitative metering chamber, for accurately limiting the volume of oil dispensed in a single lubrication cycle.

[0012] In some implementations, the pressure detection module includes a pressure sensor located at the outlet of the main oil circuit and / or branch oil circuit at the end of the distributor, for online monitoring and early warning of oil circuit blockage, pressure deficiency, and leakage faults.

[0013] In some implementations, standardized valve block units can be extended in series in any number of cases according to the lubrication point requirements, and individual valve block units can be disassembled and replaced individually.

[0014] The beneficial effects of this invention are: This technical solution adopts standardized valve block unit modular splicing, which can increase or decrease the number of lubrication branches as needed, greatly reducing product design, customization and inventory costs, and has strong versatility.

[0015] Convenient and efficient maintenance: Individual valve block units can be disassembled and replaced separately if they fail, without the need to disassemble the entire equipment, thus reducing downtime and improving maintenance efficiency.

[0016] This technical solution uses a single-channel independent drive coil module for control, in conjunction with a metering module, to precisely control the oil dosage and supply cycle, eliminating under-lubrication wear and over-lubrication leakage waste.

[0017] The pressure detection module of this technical solution collects oil circuit pressure in real time, can identify abnormalities such as pipeline blockage, insufficient pressure, and medium leakage, and provide online warnings to reduce the risk of equipment failure.

[0018] The concave-convex stop centering and matching annular high-pressure seal of this technical solution have high coaxiality and strong pressure resistance after splicing, and are suitable for high and low pressure lubrication media and various working conditions, with no risk of leakage.

[0019] This technical solution is compatible with various lubrication media such as thin oil and grease, and is suitable for intelligent centralized lubrication systems in multiple scenarios such as engineering machinery, metallurgical equipment, CNC machine tools, rail transportation, and mining machinery.

[0023] The technical solutions in the embodiments of the present invention will be clearly and completely described below. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0024] like Figures 1 to 3 As shown, the embodiments of the present invention include: a modular intelligent distributor applied to an intelligent lubrication system, comprising multiple independent standardized valve block units 100, a drive coil module 200, a metering module 300, a pressure detection module 400, a modular splicing locking structure, and an end cap assembly.

[0025] The standardized valve block unit 100 is an independent standard modular unit. Multiple standardized valve block units 100 are detachable and connected in series to form a modular base. Each valve block unit 100 has a pre-fabricated main oil supply channel 110 and an independent branch oil outlet channel 120. The side is provided with a standardized concave and convex positioning stop 130 and a centering pin hole. The mating contact surface is provided with a high-pressure sealing groove 140 to ensure the splicing positioning accuracy and sealing performance.

[0026] Each drive coil module 200 is independently installed on each standardized valve block unit 100. Each valve block unit 100 can be independently configured with one or two sets of drive coil modules 200. Each set of drive coil modules 200 individually controls the opening and closing action of a single branch valve core, realizing independent electronic control and time-sharing oil supply for each lubrication branch without interference.

[0027] The metering module 300 is mounted on the main oil supply channel 110 and includes a metering valve body 301, a metering chamber 302 disposed in the metering valve body 301, and a precision metering valve core 303 mounted in the metering chamber 302. It is used to precisely limit the volume of oil dispensed in a single lubrication cycle, control the volume of oil dispensed in a single cycle, and achieve precise oil injection at fixed points and in fixed quantities.

[0028] The pressure detection module 400 includes a pressure sensor, which is installed at the oil outlet of the main oil circuit and / or branch circuit at the end of the distributor. It is used to collect oil circuit operating pressure data in real time and realize online monitoring and early warning of oil circuit blockage, pressure shortage and leakage faults.

[0029] The modular splicing locking structure includes a through-type long locking bolt 150 and an end nut 160; adjacent standardized valve block units 100 are precisely aligned with positioning pins through concave and convex positioning stops 130. The through-type long locking bolt 150 passes through all the series valve block units 100 and works with the end nut 160 to complete the overall locking, realizing a detachable and sealed combination.

[0030] The high-pressure seal is installed in the high-pressure sealing groove 140 of the mating contact surface of the adjacent standardized valve block unit 100. It is a ring-shaped high-pressure seal, which makes the oil circuit coaxially sealed after splicing. It can withstand long-term operation of high-pressure lubricating medium without oil seepage or leakage problems.

[0031] The end cap assembly is located at both ends of the distributor. The end cap assembly is equipped with a main oil inlet connector, a plug and an external detection interface for lubricating medium access, oil circuit sealing and external connection of pressure detection module 400.

[0032] The standardized valve block unit 100 can be extended in series in any number according to the lubrication point requirements. A single valve block unit 100 can be disassembled and replaced individually without the need for overall shutdown, disassembly, and recalibration.

[0033] The beneficial effects of this technical solution are as follows: This technical solution adopts standardized valve block units in a modular fashion, which can increase or decrease the number of lubrication branches as needed, greatly reducing the cost of product design, customization and inventory preparation, and has strong versatility.

[0034] Convenient and efficient maintenance: Each valve block unit can be disassembled and replaced individually if 100% of the faults occur, without the need to disassemble the entire equipment, thus shortening downtime and improving maintenance efficiency.

[0035] The single-channel independent drive coil module 200 of this technical solution, together with the metering module 300, accurately controls the oil dosage and oil supply cycle, eliminating under-lubrication wear and over-lubrication leakage waste.

[0036] The pressure detection module 400 of this technical solution collects oil circuit pressure in real time, can identify abnormalities such as pipeline blockage, insufficient pressure, and medium leakage, and provides online early warning, thereby reducing the risk of equipment failure.

[0037] The concave-convex stop centering and matching annular high-pressure seal of this technical solution have high coaxiality and strong pressure resistance after splicing, and are suitable for high and low pressure lubrication media and various working conditions, with no risk of leakage.

[0038] This technical solution is compatible with various lubrication media such as thin oil and grease, and is suitable for intelligent centralized lubrication systems in multiple scenarios such as engineering machinery, metallurgical equipment, CNC machine tools, rail transportation, and mining machinery.

[0039] Example This embodiment provides a modular intelligent distributor with 100 standardized valve block units connected in series and a total of 6 oil outlet branches. The specific assembly and operation process is as follows: 1. Assembly and splicing process 1) The first basic standardized valve block unit 100 and the two middle sets of extended standardized valve block units 100 are aligned and fitted with the positioning pins through the side concave and convex positioning stops 130 in sequence, so as to ensure that the main oil supply channel 110 and the branch oil outlet channel 120 inside each valve block unit 100 are completely coaxial.

[0040] 2) Install an annular high-pressure seal in the high-pressure sealing groove 140 of the mating contact surface of adjacent valve block units 100 to ensure sealing performance.

[0041] 3) A modular splicing locking structure is adopted. The through-type long locking bolt 150 is passed through all 3 sets of standardized valve block units 100 connected in series in sequence, and the locking nut is tightened at the end of the distributor to complete the overall sealing and locking.

[0042] 4) Install end cap assemblies at both ends of the distributor and assemble the main oil inlet connector, plug and external detection interface in place.

[0043] 2. Component Pre-assembly Process 1) An independent drive coil module 200 is installed above each standardized valve block unit 100 to ensure that the drive coil module 200 and the corresponding branch valve core are precisely matched.

[0044] 2) Install the metering module 300 on the main oil supply channel 110, and assemble the valve body 301, precision metering valve core 303 and quantitative metering chamber 302 in place to ensure accurate oil metering.

[0045] 3) Install a pressure detection module 400 pressure sensor at the main oil line position at the end of the distributor to complete the detection line connection.

[0046] 3. Intelligent Operation Process 1) The lubricating medium enters the main oil supply channel 110 inside the distributor through the main oil inlet joint of the end cap assembly.

[0047] 2) The external control system triggers the corresponding branch drive coil module 200 to power on as needed, and drives the branch valve core to open.

[0048] 3) The lubricating medium flows through the metering module 300 in the branch oil outlet channel 120. After the oil volume is precisely limited by the metering chamber 302, it is delivered from the branch oil outlet channel 120 to the designated lubrication point of the equipment.

[0049] 4) After a single quantitative oil supply is completed, the drive coil module 200 is de-energized, the valve core is reset under the action of the reset spring, and the corresponding branch oil circuit is closed.

[0050] 4. Intelligent monitoring and expansion process 1) Throughout the entire operation, the pressure detection module 400 collects oil circuit pressure data in real time and transmits it back to the control system; when the pressure value continues to rise, it is determined that the pipeline is blocked; when the pressure drops suddenly, it is determined that the medium is leaking, and the system immediately issues a fault warning.

[0051] 2) If additional lubrication points are required, simply add a standardized valve block unit 100 to the end of the existing distributor, reinstall the through-type long locking bolt 150 and tighten the nut to complete the branch expansion. There is no need to redesign or calibrate the entire distributor.

Any equivalent structural or procedural transformations made based on the content of the present invention specification, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of the present invention.
