Description

Technical Field

[0001] The invention relates to the technical field of lubrication equipment, and in particular to a mechanical multi-channel dry oil lubrication intelligent controller. Background Art

[0002] A lubricating oil distributor is a device that can automatically, regularly and quantitatively deliver lubricants (such as lubricating oil and grease) to various lubrication points of mechanical equipment. It achieves accurate distribution and supply of lubricants through a built-in pumping system, a control valve group and a precise metering mechanism, effectively avoiding problems such as uneven, excessive or insufficient lubrication caused by manual lubrication, and ensuring good lubrication of mechanical equipment. Existing lubricating oil distributors mainly include single-line distributors, dual-line distributors and lubrication solenoid valve boxes.

[0003] For example, a patent document with authorization announcement number CN218914524U discloses a single-line distributor of lubricating grease, which includes a shell, a joint, a one-way valve, a core shaft, a gasket, a compression spring, a first sealing ring and a sleeve. One end of the shell is threadedly connected to the joint, and the other end is slidingly connected to the one-way valve located inside it. The core shaft is inserted into the joint and placed in the shell. The outer surface of the core shaft is sequentially ringed with a compression spring, a first sealing ring and a gasket from top to bottom. The sleeve is located between the first sealing ring and the compression spring. The core shaft is convexly provided with a clamping portion near the outer side wall of the joint, and the ground connection portion of the sleeve is located at one end of the sleeve near the compression spring. When in use, after the pressure on the one-way valve is cut off, the one-way valve moves toward the oil outlet under the action of the pressure difference, opens the oil suction chamber in the core shaft and seals the oil inlet, and the compression spring begins to reset without continuous application of oil pressure, pushing the sleeve, the first sealing ring and the gasket toward the oil inlet at the same time until the abutting part on the sleeve is clamped onto the clamping part of the core shaft, thereby realizing the distribution and delivery of lubricating grease.

[0004] However, for a single-line distributor, it can only supply oil point by point in sequence, and during the refueling process, it is easy for a certain lubrication point of the refueling equipment to fail or the distributor to be stuck due to clogging by foreign particles, causing the entire distributor to stop working; for a dual-line distributor, the principle of single-side refueling is that pressure drives multiple plungers to move for oiling. The failure of one plunger does not affect the operation of other plungers, resulting in an inability to determine whether each oil outlet has completed the refueling process, affecting the lubrication effect; for the lubrication solenoid valve box, its control cost is high, and the temperature in the north of the Yangtze River is low in winter, and the grease kinematic viscosity is prone to accumulate and increase, resulting in frequent solenoid valve on and off and then stuck, affecting the normal lubrication. Summary of the invention

[0005] The invention provides a mechanical multi-channel dry oil lubrication intelligent controller to solve the technical problems in the prior art that a lubricating oil distributor is easily stuck during oil distribution and has a high control cost.

[0006] In order to solve the above problems, the mechanical multi-channel dry oil lubrication intelligent controller provided by the present invention adopts the following technical solutions:

[0007] Mechanical multi-channel dry oil lubrication intelligent controller, including:

[0008] The valve body has a mounting position for mounting a plunger on its top, and two adjacent sides of the valve body are respectively provided with an oil inlet passage and an oil outlet, both of which are connected to the mounting position;

[0009] A plunger, comprising a plunger rod and a plunger body installed at the lower end of the plunger rod, the plunger body comprising a small diameter section and a large diameter section coaxially arranged and connected in sequence from bottom to top, a first oil passage extending upward to the large diameter section is opened at the bottom of the small diameter section, a second oil passage connected to the first oil passage is opened in the circumference of the small diameter section, an oil outlet passage connected to the first oil passage is opened in the circumference of the large diameter section, and the opening height of the oil outlet passage is the same as the opening height of the oil outlet;

[0010] a driving mechanism, which is drivingly connected to an end of the plunger rod away from the plunger body, so as to drive the plunger rod to rotate;

[0011] The height of the mounting position matches the height of the plunger body, and the radial dimension thereof matches the radial dimension of the large diameter section;

[0012] A control host is connected to the drive mechanism signal to control the start and stop of the drive mechanism.

[0013] The beneficial effects of the mechanical multi-channel dry oil lubrication intelligent controller provided by the present invention are:

[0014] 1. By installing the plunger in the installation position of the valve body, and designing the plunger body of the plunger to include a small diameter section and a large diameter section connected in sequence from bottom to top, the radial size of the installation position is adapted to the radial size of the large diameter section, thereby forming a storage chamber for accommodating lubricating oil between the installation position and the small diameter section, ensuring that after the lubricating oil enters the installation position from the oil inlet passage, it can sequentially pass through the second oil passage and the first oil passage opened on the small diameter section, and the oil outlet passage opened on the large diameter section, and finally flow out from the oil outlet. By controlling the start and stop of the driving mechanism by the control host, the rotation of the plunger in the installation position can be precisely controlled, and the correspondence between the oil outlet passage and the oil outlet can be changed, so that the flow path of the lubricating oil can be accurately changed. In this process, only the outer surface of the small diameter section contacts the lubricating oil, and the outer surface of the large diameter section (i.e., the rotating surface) does not contact the flowing lubricating oil, thereby avoiding the situation where the impurities carried in the lubricating oil jam the plunger, and ensuring the smoothness of the flow of the lubricating oil;

[0015] 2. The rotation of the plunger in the installation position is controlled by controlling the start and stop of the driving mechanism of the host. The manufacturing cost is lower, the stability is better, and it is not easily affected by the working environment. It can effectively avoid the opening and recovery failure of the plunger due to the increase in grease viscosity in winter, and ensure the stability of lubricating oil distribution. The manufacturing and maintenance costs are low and the cost performance is high.

[0016] Through the above arrangement, the present invention effectively solves the technical problems in the prior art that the lubricating oil distributor is easy to get stuck during oil distribution and has high control cost.

[0017] Furthermore, the oil outlet comprises a first oil outlet, a second oil outlet and a third oil outlet which are opened on the side of the valve body and are evenly spaced in the horizontal direction.

[0018] Furthermore, the interior of the valve body is provided with a first connecting channel, a second connecting channel and a third connecting channel extending horizontally, the first connecting channel is used to connect the first oil outlet with the installation position, the second connecting channel is used to connect the second oil outlet with the installation position, and the third connecting channel is used to connect the third oil outlet with the installation position.

[0019] Further, the first connecting channel and the third connecting channel are coaxially arranged, and an extending direction of the second connecting channel is perpendicular to an axial direction of the first connecting channel.

[0020] Furthermore, the oil outlet channel includes oil outlet channel one, oil outlet channel two, oil outlet channel three and oil outlet channel four, which are arranged at circumferential intervals in the large diameter section, oil outlet channel one and oil outlet channel three are respectively located on two opposite sides of the first oil channel, the extension direction of oil outlet channel two is perpendicular to the axial direction of oil outlet channel one, and the angle between oil outlet channel four and oil outlet channel one is an acute angle or an obtuse angle.

[0021] Beneficial effect: by opening three oil outlets connected to the mounting position on the valve body, four oil outlet channels are arranged on the large diameter section, and oil outlet channel one and oil outlet channel three are respectively located on two opposite sides of the first oil channel, the extension direction of oil outlet channel two is perpendicular to the axial direction of oil outlet channel one, and the angle between oil outlet channel four and oil outlet channel one is an acute angle or an obtuse angle, the correspondence between the oil outlet channels and the oil outlets can be changed by rotating the plunger, thereby controlling the number and position of the oil outlets that can discharge oil, realizing refueling of any lubrication point, refueling of any two lubrication points, and refueling of three lubrication points at the same time, and the refueling time can be flexibly controlled.

[0022] Furthermore, the driving mechanism is a stepping motor or a servo motor.

[0023] Furthermore, the control host is a PLC control host.

[0024] Beneficial effects: By using PLC to control the start and stop of the drive mechanism, the reliability is higher, and no matter how the type of drive mechanism and control requirements change, it can be quickly adapted by modifying the PLC program, which is more flexible and can effectively ensure the accuracy and stability of lubricating oil refueling.

[0025] Furthermore, the number of the mounting positions is two, the two mounting positions are connected by a connecting oil channel, and the oil inlet channel is connected to the connecting oil channel for supplying oil to the two mounting positions at the same time; or the number of the mounting positions is two, and each mounting position is connected to one oil inlet channel.

[0026] Furthermore, the first oil channel extends vertically upward from the center of the bottom surface of the small-diameter section.

[0027] Furthermore, the number of the second oil passages is two. BRIEF DESCRIPTION OF THE DRAWINGS

[0042] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Those skilled in the art should know that the embodiments described below are part of the embodiments of the present disclosure, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0043] It should be noted that the main concept of the mechanical multi-channel dry oil lubrication intelligent controller provided by the present invention is: by setting a plunger including a plunger body and a plunger rod 4, and making the plunger body include a small diameter section 5 and a large diameter section 6 connected in sequence from bottom to top, the radial size of the mounting position 2 opened on the valve body 1 is adapted to the radial size of the large diameter section 6 of the plunger, so that after the plunger is installed in the mounting position 2, a storage chamber for containing lubricating oil is formed between the mounting position 2 and the small diameter section 5. When the lubricating oil enters the mounting position 2 from the oil inlet channel 3, it passes through the second oil channel 8 and the first oil channel 7 opened on the small diameter section 5 in sequence, and then flows through the oil outlet channel opened on the large diameter section 6, and finally flows out from the oil outlet opened on the valve body 1 and connected to the mounting position 2, and the start and stop of the drive mechanism are controlled by the control host. By using a driving mechanism to drive the plunger to rotate in the installation position 2, the correspondence between the oil outlet channel and the oil outlet can be changed, so that the flow path of the lubricating oil can be accurately changed to achieve precise control of the lubricating oil filling; during the rotation of the plunger, only the outer surface of the small diameter section 5 is in contact with the lubricating oil, and the outer surface of the large diameter section 6 (i.e., the rotating surface) is not in contact with the lubricating oil, which can avoid the impurities carried in the lubricating oil from jamming the plunger and ensure the smooth flow of the lubricating oil; by controlling the start and stop of the driving mechanism by the control host to control the rotation of the plunger in the installation position 2, the manufacturing and maintenance costs are lower, and it can adapt to changes in various working environments. It can effectively avoid the opening and recovery failures of the plunger due to the increase in grease viscosity in winter, and ensure the stability of the lubricating oil distribution.

[0044] After introducing the basic principle of the present invention, various non-limiting embodiments of the present invention are described in detail below. The number of any element in the drawings is for illustration and not for limitation, and any naming is only for distinction and does not have any limiting meaning.

[0045] The principle and spirit of the present invention are explained in detail below with reference to several representative embodiments of the present invention.

[0046] Embodiment 1 of the mechanical multi-channel dry oil lubrication intelligent controller provided by the present invention:

[0047] like Figures 1 to 11 As shown, the mechanical multi-channel dry oil lubrication intelligent controller includes a valve body 1, the top of the valve body 1 has a mounting position 2 for mounting a plunger, the lower end of the plunger is mounted in the mounting position 2, and the upper end is transmission-connected to a driving mechanism so that the plunger is driven to rotate by the driving mechanism, and the driving mechanism is signal-connected to a control host so that the start and stop of the driving mechanism can be controlled by the control host.

[0048] About the valve body 1. An oil inlet passage 3 is provided on the front side of the valve body 1, and the axis where the oil inlet passage 3 is located divides the valve body 1 into a left unit and a right unit which are symmetrical about the axis. Next, the structural composition of the left unit of the valve body 1 and the connection relationship between the oil inlet passage 3 and the left unit and the right unit are introduced.

[0049] A mounting position 2 for mounting a plunger is provided at the top of the left unit, and a first oil outlet 9, a second oil outlet 10 and a third oil outlet 11 are provided on the left side thereof, which are evenly spaced in the horizontal direction from front to back. A first connecting channel 12, a second connecting channel 13 and a third connecting channel 14 extending horizontally are provided in the left unit. The first connecting channel 12 is used to connect the first oil outlet 9 and the mounting position 2, the second connecting channel 13 is used to connect the second oil outlet 10 and the mounting position 2, and the third connecting channel 14 is used to connect the third oil outlet 11 and the mounting position 2, and the first connecting channel 12 and the third connecting channel 14 are coaxially arranged, and the extension direction of the second connecting channel 13 is perpendicular to the axial direction of the first connecting channel 12.

[0050] The right unit is a mirror image of the left unit, having the same geometric shape, component layout and functional features as the left unit (but in opposite directions), which will not be described in detail here.

[0051] The left unit is connected to the right unit via a connecting oil passage 19, and the oil inlet passage 3 is connected to the connecting oil passage 19 so as to supply oil to the left and right mounting positions 2 simultaneously.

[0052] About the plunger. The plunger includes a plunger rod 4 and a plunger body installed at the lower end of the plunger rod 4, the plunger body includes a small diameter section 5 and a large diameter section 6 which are coaxially arranged and connected in sequence from bottom to top, the bottom of the small diameter section 5 is provided with a first oil passage 7 extending upward to the large diameter section 6, the axial direction of the small diameter section 5 is provided with a second oil passage 8 connected with the first oil passage 7, the circumferential direction of the large diameter section 6 is provided with an oil outlet passage connected with the first oil passage 7, the opening height of the oil outlet passage is the same as the opening height of the first oil outlet 9, the second oil outlet 10 and the third oil outlet 11; the height of the mounting position 2 matches the height of the plunger body, and its radial dimension matches the radial dimension of the large diameter section 6.

[0053] Specifically, a first oil passage 7 extending vertically upward to the large diameter section 6 is opened at the center of the bottom of the small diameter section 5 ; and the number of the second oil passages 8 is two.

[0054] Specifically, the oil outlet channels include oil outlet channel 1 15, oil outlet channel 2 16, oil outlet channel 3 17 and oil outlet channel 4 18 which are arranged at circumferential intervals in the large diameter section 6, wherein oil outlet channel 15 and oil outlet channel 3 17 are respectively located on two opposite sides of the first oil channel 7, the extension direction of oil outlet channel 2 16 is perpendicular to the axial direction of oil outlet channel 1 15, and the angle between oil outlet channel 4 18 and oil outlet channel 1 15 is an acute angle.

[0055] Specifically, the angle between the oil outlet passage 4 18 and the oil outlet passage 1 15 is 45°.

[0056] About the driving mechanism. The driving mechanism is a stepper motor or a servo motor, which is mounted on the valve body 1, and its output end is downward and drivingly connected to the top end of the plunger rod 4, so as to drive the plunger rod 4 to rotate.

[0057] About the control host. The control host is a PLC control host, that is, a programmable logic control host, which is connected to the drive mechanism signal to control the start and stop of the drive mechanism, thereby controlling the rotation of the plunger, and further realizing the control of lubricating oil delivery.

[0058] It should be noted that the single-line and double-line distributors commonly used in the prior art use a plunger to push the grease to transport and distribute the lubricating oil. During use, the plunger is prone to get stuck. Compared with this distributor, the present invention changes the way the plunger pushes the grease to transport the grease to the axial rotation of the plunger. The active surface of the plunger (i.e., the outer surface of the large-diameter section 6) does not contact the flowing grease, thereby avoiding the phenomenon that impurities in the grease get stuck in the plunger; the solenoid valve commonly used in the prior art controls the on-off of the pipeline to control the distribution of lubricating oil. The solenoid valve used is a general hydraulic industry solenoid valve, which is not completely suitable for the dry oil lubrication method. The on-off force of the solenoid valve is greatly affected by the environment in winter, and the plunger is prone to opening and returning failures, and the movement of the solenoid valve plunger is easily affected by impurities and causes jamming. Compared with this distribution method, the present invention uses a stepper motor or a servo motor as a driving mechanism to directly drive the plunger to rotate. The plunger is not affected by the season during the rotation process, and it can be ensured that the driving mechanism is not affected by the sharp increase in the viscosity of the low-temperature grease when driving the plunger to move in winter.

[0059] In addition, the existing single-line progressive distributor can only supply oil point by point in sequence, and the existing double-line distributor can only supply oil to the other side in the same way after the pressure pushes all the plungers on one side to move together. The present invention adopts a dedicated oil channel based on mechanical principles, and controls the rotation of the driving mechanism through the PLC control host. After the radial oil channel port of the plunger corresponds to the oil channel port of the valve body 1, the purpose of refueling each lubrication point one by one and controlling the refueling time individually can be achieved; the driving mechanism drives the plunger to rotate at different angles to achieve simultaneous refueling of any single lubrication point, any two lubrication points or multiple lubrication points.

[0060] The mechanical multi-channel dry oil lubrication intelligent controller provided by the present invention has the following innovations:

[0061] 1. The present invention is a new oil distribution method added on the basis of the original solenoid valve oil distribution method, the double-line distributor oil distribution method and the single-line progressive distributor oil distribution method, and the plunger is directly driven to rotate by a driving mechanism such as a stepping motor or a servo motor, thereby avoiding the situation that the plunger in the oil channel is stuck during use, and can realize simultaneous oil discharge from any oil outlet, with a simple structure and stable and reliable performance;

[0062] 2. The present invention can effectively replace the use of lubricating solenoid valve boxes and reduce the use cost by reducing the use of multiple high-performance solenoid valves;

[0063] 3. The present invention can effectively replace the use of a lubricating solenoid valve box. By rotating the plunger, the grease oil channel is connected to the oil channel of the valve body 1. The rotating surface of the plunger (i.e., the outer surface of the large diameter section 6) does not contact the grease, which can avoid the stuck phenomenon caused by the movement of the plunger and avoid the abnormal operation of the plunger in winter.

[0064] 4. The present invention opens the grease oil circuit by rotating the plunger, and the rotating surface of the plunger (i.e., the outer surface of the large diameter section 6) does not contact the grease, which can replace the use of single-line and double-line distributors in the dry oil lubrication industry, and can effectively avoid the phenomenon that the single-line distributor does not move as a whole due to a single point failure, and can also avoid the situation that the double-line distributor does not lubricate a single point and the plunger does not move into place;

[0065] 5. The structure of the present invention is simple, and only includes the valve body 1 and the plunger. In the process of processing the plunger, only the processing accuracy of the large diameter section 6 is required to be high. The radial dimension of the large diameter section 6 is large, and the processing technology is simple. The processing accuracy requirement for the plunger rod 4 connected to the driving mechanism is low. In the process of processing the valve body 1, only the part that matches the large diameter section 6 has a high processing accuracy requirement, but this part is a through hole, and its processing technology is simple and the cost is low. Therefore, the processing technology and processing cost of the present invention are much lower than the processing difficulty and production cost of the existing distributor.

[0066] 6. In the present invention, when there is no failure in the driving mechanism, the stable operation of each oil outlet can be absolutely guaranteed;

[0067] 7. The present invention can realize the independent oil supply of each oil outlet, and can also realize the simultaneous oil supply of multiple lubrication points or the simultaneous oil supply of any designated points. After confirming that the lubrication points are fault-free at each independent oil outlet, the lubrication points to be refueled can be opened at the same time to refuel at the same time, thereby reducing the overall refueling time required for all lubrication points;

[0068] 8. Compared with the single-line and double-line lubrication distributor, the technical solution provided by the present invention has a simple principle and is easy to operate. Lubrication is performed by controlling the stepper motor or servo motor to rotate the plunger through the PLC control host. The oil channel is simple in form, the processing difficulty is low, and the later maintenance is simple.

[0069] 9. The present invention can accurately add oil to each lubrication point, avoiding the waste of oil and the pollution of the environment caused by oil overflow due to the same oil output from the oil outlets of single-line and double-line distributors, and saving the cost of hazardous waste treatment in the later stage.

[0070] The working principle of the mechanical multi-channel dry oil lubrication intelligent controller provided by the present invention is:

[0071] First, install the plunger in the installation position 2, then supply lubricating oil to the mechanical multi-channel dry oil lubrication intelligent controller through the oil inlet channel 3, and the lubricating oil enters the large diameter section 6 through the connecting oil channel 19, the second oil channel 8, and the first oil channel 7 in sequence. According to the lubrication needs, the PLC control host controls the drive mechanism to start, so as to control the plunger to rotate in the installation position 2, change the connection between the oil outlet channel and the oil outlet, so that the three oil outlets can be refueled at the same time (such as Figure 5 As shown), the first oil outlet 9 and the third oil outlet 11 are refueled at the same time (as shown Figure 6 As shown), the first oil outlet 9 and the second oil outlet 10 are refueled at the same time (as shown Figure 7 As shown), the second oil outlet 10 and the third oil outlet 11 are refueled at the same time (as shown Figure 8 As shown), the third oil outlet 11 is refueled separately (as shown Fig. 9 As shown), the second oil outlet 10 is refueled separately (as shown Fig.10 As shown) and the first oil outlet 9 for refueling (as shown) Fig.11 As shown in the figure, the lubrication position and refueling time can be flexibly changed, and finally accurate refueling of different lubrication points can be achieved.

[0072] Embodiment 2 of the mechanical multi-channel dry oil lubrication intelligent controller provided by the present invention:

[0073] The main difference between it and Example 1 is:

[0074] In Example 1, the left unit and the right unit are connected via a connecting oil passage, and the oil inlet passage is connected to the connecting oil passage, so as to supply oil to both the left and right installation positions at the same time.

[0075] In this embodiment, the left unit and the right unit are each connected to an oil inlet passage.

[0076] Embodiment 3 of the mechanical multi-channel dry oil lubrication intelligent controller provided by the present invention:

[0077] The main difference between it and Example 1 is:

[0078] In Example 1, the angle between the oil outlet passage 4 and the oil outlet passage 1 is an acute angle.

[0079] In this embodiment, the angle between the oil outlet passage 4 and the oil outlet passage 1 is an obtuse angle.

[0080] Embodiment 4 of the mechanical multi-channel dry oil lubrication intelligent controller provided by the present invention:

[0081] The main difference between it and Example 1 is:

[0082] In Example 1, the number of oil outlets is three, and the number of oil outlet channels is four.

[0083] In this embodiment, the number of the oil outlets is any number, and the number of the oil outlet passages is greater than the number of the oil outlets.
