Description

Technical Field

[0001] This utility model relates to the field of anchor winch technology, and in particular to a marine anchor winch. Background Technology

[0002] As a core large deck machine of a ship, the anchor winch is widely installed on the main deck at the bow and stern. It undertakes key tasks such as raising and lowering anchors and anchor chains, and securing mooring lines. Its operational stability and safety directly determine the reliability of ship berthing and anchoring operations. It plays an irreplaceable role in ensuring the safety of ship navigation and the efficiency of port operations. With the development of the shipbuilding industry, modern anchor winches generally integrate multiple locking mechanisms. Through optimized braking logic and structural design, the safety performance of the equipment under heavy loads and complex sea conditions has been significantly improved. For example, after the ship has dropped anchor, it can effectively prevent the winch drum from rotating unexpectedly and avoid safety accidents caused by the anchor chain loosening. It has become an indispensable key piece of equipment in the ship deck system. However, existing ship anchor winches still suffer from two major technical pain points in practical applications, which seriously affect their performance and service life. On the one hand, there is a common problem of uneven rope winding during rope (or anchor chain) winding operations. This is illustrated by the "Marine Anchor Winch with Dual Braking Structure" disclosed in Chinese Utility Model Patent Application No. 202122733247.2. For example, although the device enhances braking safety by installing braking components at both ends of the cable drum, it does not optimize the design for the rope winding trajectory. In actual operation, the rope is prone to local accumulation and entanglement on the surface of the cable drum, resulting in uneven force between rope layers and a shift in the center of gravity after winding. This not only increases the risk of jamming during subsequent cable release, but may also cause deformation of the cable drum or wear of the rope due to excessive local load, shortening the service life of the equipment and the rope. At the same time, when the rope is working in water, it is easy to adhere to impurities such as scum, algae, and silt. The existing device lacks an effective impurity cleaning mechanism. After the impurities are wound up with the rope, they will adhere to the inner wall of the cable drum, the gap between the shaft and the support column, etc., which is not only difficult to clean, but also aggravates friction and contamination between components. Long-term accumulation can easily cause transmission jamming and affect the normal operation of the anchor winch. On the other hand, existing anchor winches generally lack automatic lubrication mechanisms. This deficiency is particularly pronounced at the bearings at both ends of the cable drum. During operation, the cable drum must withstand the heavy tension of the anchor chain or rope, and the bearings at both ends are under high-intensity pressure and high-speed rotational friction for extended periods, placing extremely high demands on lubrication performance. In current technology, manual lubrication is typically relied upon periodically, which is not only cumbersome and costly to maintain, but also difficult to precisely control the amount and frequency of lubrication. Obviously, if lubrication is not timely during use, the bearings will lack effective oil film protection, leading to a sharp increase in the coefficient of friction. This can cause abnormal noise and overheating, or even serious malfunctions such as bearing wear, seizure, and shaft deformation. Even with manual lubrication, oil leakage is common. Excessive oil level can lead to oil leakage and heat buildup, while insufficient oil level can prevent the formation of a complete oil film. In addition, increased bearing friction resistance directly increases the load on the drive system, motor, or hydraulic system, resulting in increased energy consumption and accelerated wear of drive components. This further reduces the overall operating efficiency and reliability of the anchor winch, causing numerous inconveniences to daily ship operations. It is evident that existing ship anchor winches have significant technical shortcomings in terms of rope winding uniformity and automatic lubrication of key components. Although some devices have improved safety through optimized braking structures, they have failed to balance operational efficiency with the need for long-term equipment maintenance. There is an urgent need to address these technical pain points through structural improvements and functional innovations to meet the requirements of modern ships for efficient, stable, and low-loss operation of anchor winches. Utility Model Content

[0003] To address the aforementioned problems, this utility model proposes a marine anchor winch to more accurately resolve the problems described above.

[0004] This utility model is achieved through the following technical solution: This utility model proposes a marine anchor winch, including a mounting plate, side plates fixedly mounted on both sides of the top of the mounting plate, a side plate fixedly mounted on the top of the side plate, a bearing rotatably connected to the middle of the side plate, a winding roller fixedly mounted on the inner side of the bearing, a straightening mechanism fixedly mounted in the middle of the top of the mounting plate, a self-lubricating mechanism fixedly mounted on the rear side of the top of the mounting plate, and an external drive device connector provided on the outer side of one bearing. The self-lubricating mechanism includes a support frame, a top seat fixedly installed on the top of the support frame, a tank fixedly installed at the front end of the top seat, a pumping module fixedly installed at the bottom output end of the tank, the output end of the pumping module being located above the bearing, and the pumping module being connected to the straightening mechanism via a transmission.

[0005] Furthermore, a refueling pipe is fixedly connected to one side of the top of the tank, and a sealing cap is threaded onto the top of the refueling pipe.

[0006] Furthermore, the correction mechanism includes a guide rail, a side seat fixedly mounted at one end of the guide rail, a drive motor fixedly mounted on the outer side of the side seat, a lead screw rotatably connected inside the guide rail, the output end of the drive motor being connected to the end of the lead screw via a coupling, a slider threadedly connected to the outer surface of the lead screw, a correction arm fixedly mounted on the outer side of the slider, a correction ring fixedly mounted at the upper end of the correction arm, and a transmission module fixedly mounted on the rear side of the correction arm, the transmission module being drively connected to the pumping module.

[0007] Furthermore, the pumping module includes an oil discharge hopper, which is fixedly installed at the bottom of the tank. An oil discharge pipe is fixedly installed at the bottom of the oil discharge hopper. Oil injection pipes are fixedly installed at both output ends of the oil discharge pipe. The outer output end of the oil injection pipe is located above the bearing. A solenoid valve is fixedly installed at the input end of the oil injection pipe. An auger is rotatably connected inside the oil discharge pipe. A gear is rotatably connected to the bottom of the oil injection pipe. The gear is connected to the bottom of the auger through a coupling. The gear is connected to the transmission module for transmission.

[0008] Furthermore, a horizontal plate is fixedly installed at the upper end of the support frame, and a protective shell is fixedly installed at the front end of the horizontal plate, the protective shell covering the outside of the gear.

[0009] Furthermore, the transmission module includes a connecting arm, which is fixedly connected to the rear side of the correction arm. A rack is fixedly installed at the upper end of the connecting arm, and the rack is slidably connected to the inside of the protective housing. The rack and gear are meshed together.

[0010] The beneficial effects of this utility model are: 1. During the application of this technical solution, the setting of a straightening mechanism enables the straightening ring to move linearly back and forth with the slider during use, guiding the anchor chain or rope to be evenly distributed along the axial direction of the winding roller. At the same time, the straightening ring can perform preliminary sorting on the surface of the rope, reducing the impurities attached to the rope, thereby achieving the effect of uniform winding of the anchor chain or rope and reducing the contamination of impurities inside the equipment. This solves the problems of uneven winding caused by the rope easily getting tangled in one place during the winding of the anchor winch in the prior art, as well as the problem of impurities entering the equipment with the rope and causing contamination. At the same time, the bellows cover on the outside of the guide rail can cover the lead screw, preventing the lead screw from being contaminated by external dust and impurities, ensuring smooth thread connection between the lead screw and the slider, reducing lead screw wear, ensuring stable operation of the straightening mechanism, further improving the overall operational stability of the equipment, and solving the problem of the lead screw being easily affected by impurities, causing the straightening mechanism to malfunction in the prior art. 2. During the application of this technical solution, by setting up a self-lubricating mechanism linked with the straightening mechanism, the straightening mechanism can drive the transmission module to rotate the auger during use. The lubricating oil in the tank is transported to the bearing through the oil injection pipe. At the same time, the oil distribution pipe can transport some lubricating oil to the meshing parts of the gear and rack, thereby achieving the effect of automatic lubrication and continuous lubrication of key components. This solves the problems of cumbersome manual oil injection operation, high maintenance costs, and difficulty in accurately controlling the amount and cycle of oil injection in the existing technology of anchor winches. Continuous lubrication can reduce the frictional loss of bearings and meshing parts, reduce the probability of failures such as bearing jamming and shaft deformation, and reduce the load on the external drive system and reduce energy consumption. This solves the problems of rapid wear of key components and high load on the drive system due to lack of effective lubrication in the existing technology. Attached Figure Description

[0013] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example 1

[0014] A marine anchor winch includes a mounting plate 1, side plates 2 fixedly mounted on both sides of the top of the mounting plate 1, a side disc 3 fixedly mounted on the top of the side plate 2, a bearing 4 rotatably connected to the middle of the side disc 3, a winding roller 5 fixedly mounted on the inner side of the bearing 4, a straightening mechanism 6 fixedly mounted in the middle of the top of the mounting plate 1, a self-lubricating mechanism 7 fixedly mounted on the rear side of the top of the mounting plate 1, and an external drive device connector 8 provided on the outer side of one bearing 4. The self-lubricating mechanism 7 includes a support frame 71, a top seat 72 fixedly mounted on the top of the support frame 71, a tank 73 fixedly mounted on the front end of the top seat 72, and a pumping module 74 fixedly mounted on the bottom output end of the tank 73. The output end of the pumping module 74 is located above the bearing 4. The pumping module 74 and the straightening mechanism 6 are connected by a transmission. During the application of this device, it cooperates with an external drive device by setting an external drive device connector 8, so that external power can be transmitted to the winding roller 5 during use. The winding roller 5 rotates around the bearing 4 in the middle of the side plate 3, thereby realizing the winding operation of the anchor chain or rope. At the same time, the straightening mechanism 6 in the middle of the top of the mounting plate 1 can guide the anchor chain or rope during the winding process to ensure a more regular winding process. The self-lubricating mechanism 7 on the rear side of the top of the mounting plate 1 can provide lubrication for the key parts of the equipment. The self-lubricating mechanism 7 includes a support frame 71 that supports the top seat 72. The tank 73 at the front end of the top seat 72 stores lubricating oil. The pumping module 74 at the bottom of the tank 73 delivers the lubricating oil to the bearing 4. The pumping module 74 is connected to the straightening mechanism 6, enabling simultaneous lubrication during the operation of the straightening mechanism 6. This structural design ensures more stable and orderly winding of the anchor chain or rope, preventing chaotic winding from affecting operational efficiency. Furthermore, the synchronous lubrication of the self-lubricating mechanism 7 reduces frictional wear on components such as the bearing 4 during operation, extends component lifespan, and reduces equipment maintenance frequency. It also eliminates the need for separate lubrication system control, simplifying the operation process and making the entire anchor winch more efficient and reliable, further ensuring the smooth operation of ship anchoring or mooring.

[0015] Combination Figures 1-3 As shown, a refueling pipe 75 is fixedly connected to one side of the top of the tank 73. A sealing cap 76 is threadedly connected to the top of the refueling pipe 75. The straightening mechanism 6 includes a guide rail 61. A side seat 62 is fixedly installed at one end of the guide rail 61. A drive motor 63 is fixedly installed on the outside of the side seat 62. A lead screw 64 is rotatably connected inside the guide rail 61. The output end of the drive motor 63 is connected to the end of the lead screw 64 through a coupling. A slider 65 is threadedly connected to the outer surface of the lead screw 64. A straightening arm 66 is fixedly installed on the outside of the slider 65. A straightening ring 67 is fixedly installed at the upper end of the straightening arm 66. A transmission module 68 is fixedly installed on the rear side of the straightening arm 66. The transmission module 68 and the pumping module 74 are connected in a transmission manner.

[0016] In the above-described embodiments of this application, during the application of this device, by setting up an oil filling pipe 75 and a sealing cap 76, lubricating oil can be added to the tank 73 through the oil filling pipe 75 by opening the sealing cap 76 during use. After replenishment, tightening the sealing cap 76 can prevent lubricating oil leakage or impurities from entering, providing a stable oil source for the self-lubricating mechanism 7. The drive motor 63 in the straightening mechanism 6 is started, and the output end of the drive motor 63 drives the lead screw 64 inside the guide rail 61 to rotate through the coupling. When the lead screw 64 rotates, it drives the slider 65 connected to the outer surface thread to move. The slider 65 drives the outer straightening arm 66 to move synchronously. The straightening ring 67 at the upper end of the straightening arm 66 moves with the straightening arm 66. During the winding operation, it can guide the anchor chain or rope, and at the same time, the straightening arm The transmission module 68 on the rear side of the straightening arm 66 moves with the straightening arm 66, thereby driving the pumping module 74 connected to it. The pumping module 74 delivers the lubricating oil in the tank 73 to the bearing 4, thus lubricating the bearing 4. This design allows the straightening mechanism 6 to guide the anchor chain or rope while simultaneously coordinating with the pumping module 74 to deliver lubricating oil. This ensures the regularity of the anchor chain or rope during winding and provides timely lubrication to the bearing 4, reducing frictional loss during bearing 4 rotation and extending the service life of the bearing 4. At the same time, there is no need to set up a separate drive component for the pumping module 74, which simplifies the structure and reduces energy consumption. The cooperation between the oil filling pipe 75 and the sealing cap 76 also makes the lubricating oil replenishment operation more convenient and avoids the problem of impurities contaminating the lubricating oil during the replenishment process. Example 2

[0017] Combination Figures 2-5As shown, the pumping module 74 includes an oil discharge hopper 741, which is fixedly installed at the bottom of the tank 73. An oil discharge pipe 742 is fixedly installed at the bottom of the oil discharge hopper 741. An oil injection pipe 743 is fixedly installed at both output ends of the oil discharge pipe 742. The outer output end of the oil injection pipe 743 is located above the bearing 4. A solenoid valve 744 is fixedly installed at the input end of the oil injection pipe 743. An auger 745 is rotatably connected inside the oil discharge pipe 742. A gear 746 is rotatably connected to the bottom of the oil injection pipe 743. The gear 746 is connected to the bottom of the auger 745 through a coupling. The gear 746 is connected to the transmission module 68. A horizontal plate 747 is fixedly installed at the upper end of the support frame 71. A protective housing 748 is fixedly installed at the front end of 47. The protective housing 748 covers the outside of the gear 746. The transmission module 68 includes a connecting arm 681, which is fixedly connected to the rear side of the straightening arm 66. A rack 682 is fixedly installed at the upper end of the connecting arm 681. The rack 682 is slidably connected to the inside of the protective housing 748. The rack 682 and the gear 746 are meshed together. An oil injection pipe 743 is located on the side outside the solenoid valve 744 and is fixedly connected to an oil distribution pipe 749. The output end of the oil distribution pipe 749 is connected to the inside of the protective housing 748. An oil guide groove 9 is opened at the upper inner side of the side plate 3. The oil guide groove 9 extends to the bearing 4. The oil injection pipe 743 is located inside the oil guide groove 9.

[0018] In the above-described embodiments of this application, during the application of this device, by setting up a pumping module 74, a transmission module 68, and a protective housing 748, the transmission module 68 can drive the pumping module 74 to complete the lubricating oil delivery during use, while the protective housing 748 can protect key components. When the connecting arm 681 in the transmission module 68 moves with the straightening arm 66, it will drive the upper rack 682 to slide inside the protective housing 748. The rack 682 meshes with the gear 746, driving the gear 746 to rotate. The gear 746 drives the auger 745 inside the oil drain pipe 742 to rotate through the coupling. At this time, the solenoid valve 744 at the input end of the oil injection pipe 743 is opened, and the lubricating oil in the tank 73 will first flow into the oil drain hopper 741, and then enter the oil drain pipe 742 through the oil drain hopper 741. The rotation of the auger 745 pushes the lubricating oil in the oil drain pipe 742 towards the oil injection pipe 743. Part of the lubricating oil passes through the oil injection pipe. The lubricating oil is delivered to bearing 4 via oil supply pipe 743, and another portion is delivered to the interior of protective housing 748 via oil distribution pipe 749 on oil supply pipe 743. Oil supply pipe 743 is located in oil guide groove 9, allowing lubricating oil to flow precisely to bearing 4 along oil guide groove 9. This design allows lubricating oil to be delivered to both bearing 4 and the interior of protective housing 748 simultaneously, achieving lubrication of bearing 4 and the meshing parts of rack 682 and gear 746, reducing frictional losses in these two critical components. Protective housing 748 covers gear 746 to prevent external impurities from affecting the meshing transmission between gear 746 and rack 682. Oil guide groove 9 guides lubricating oil to act precisely on bearing 4, avoiding lubricating oil waste. Solenoid valve 744 controls the on / off of lubricating oil delivery, ensuring that oil is supplied only when lubrication is needed. The overall structure works together to make the lubrication process more precise and efficient, while eliminating the need for a separate drive component for pumping module 74, further simplifying the structure and reducing energy consumption.

[0019] The working principle and advantages of this utility model are as follows: During the application of this device, the sealing cap 76 of the oil filling pipe 75 at the top of the tank 73 is opened, and gear 746 lubricating oil is injected into the tank 73 through the oil filling pipe 75. After the injection is completed, the sealing cap 76 is tightened. Then, the external drive equipment is started, and the power is transmitted to the winding roller 5 through the external drive equipment connector 8. The winding roller 5 rotates around the bearing 4 and begins the winding operation of the anchor chain or rope. At the same time, the drive motor 63 in the straightening mechanism 6 is started. The output end of the drive motor 63 drives the lead screw 64 to rotate through the coupling. The rotation of the lead screw 64 causes the slider 65 with the threaded connection on the outer surface to move linearly back and forth along the guide rail 61. The slider 65 drives the straightening arm 66 to move synchronously, and the straightening arm 66 drives the upper straightening ring 67 to move. The straightening ring 67 is fitted with an anchor chain or rope and moves back and forth with the slider 65. During this process, the mounting plate 1 provides basic support for the entire anchor winch, the side plate 2 supports the side plate 3, the side plate 3 laterally limits the winding roller 5, the bearing 4 reduces the friction when the winding roller 5 rotates, so that the winding roller 5 can rotate stably, and the bellows cover set on the outside of the guide rail 61 covers the lead screw 64 to prevent the lead screw 64 from being contaminated by external dust and impurities, ensures the smooth thread connection between the lead screw 64 and the slider 65, reduces the wear of the lead screw 64, and ensures the stable movement of the straightening mechanism 6. Next, while the straightening mechanism 6 is operating, the self-lubricating mechanism 7 begins to work in conjunction. When the straightening arm 66 moves, it drives the transmission module 68 behind it to move synchronously. The connecting arm 681 in the transmission module 68 moves with the straightening arm 66. The connecting arm 681 drives the rack 682 at its upper end to slide along the inside of the protective shell 748. During the sliding process, the rack 682 meshes with the gear 746, driving the gear 746 to rotate. The gear 746 drives the auger 745 inside the oil drain pipe 742 to rotate through the coupling. At this time, the solenoid valve 744 at the input end of the oil injection pipe 743 is opened, and the lubricating oil at the bottom of the tank 73 enters the oil drain hopper 741. The oil drain hopper 741 guides the lubricating oil into the oil drain pipe 742. The rotation of the auger 745 pushes the lubricating oil in the oil drain pipe 742 towards the oil injection pipe 743. The lubricating oil is delivered to the bearing 4 through the oil injection pipe 743. At the same time, the oil distribution pipe 74 fixed on the oil injection pipe 743... 9. Part of the lubricating oil is delivered to the inside of the protective housing 748. The oil injection pipe 743 is located inside the oil guide groove 9 at the upper end of the inner side of the side plate 3. The lubricating oil flows along the oil guide groove 9 to the bearing 4. The support frame 71 provides support for the top seat 72 and the horizontal plate 747. The tank body 73 is installed on the top seat 72. The protective housing 748 at the front end of the horizontal plate 747 covers the outside of the gear 746 to prevent the gear 746 from contacting external impurities, protect the meshing structure of the gear 746 and the rack 682, and ensure stable transmission. The oil drain hopper 741 guides the lubricating oil in the tank body 73 to the oil drain pipe 742. The solenoid valve 744 controls the opening and closing of the oil injection pipe 743. The oil distribution pipe 749 lubricates the meshing part of the rack 682 and the gear 746, reduces the friction loss of this part, and extends the service life of the transmission structure. The oil guide groove 9 guides the lubricating oil to flow precisely to the bearing 4 to prevent the lubricating oil from being lost and to ensure that the lubricating oil fully acts on the bearing 4. Then, as the winding operation continues, the straightening mechanism 6 and the self-lubricating mechanism 7 operate in coordination. The drive motor 63 continuously drives the lead screw 64 to rotate, and the slider 65 drives the straightening arm 66 and the straightening ring 67 to maintain linear reciprocating motion, ensuring that the anchor chain or rope is always wound evenly along the axial direction of the winding roller 5. The rack 682 slides continuously with the connecting arm 681, driving the gear 746 and the auger 745 to rotate, continuously pushing the lubricating oil through the oil injection pipe 743 and the oil guide groove 9 to the bearing 4. The oil distribution pipe 749 also continuously... Lubricating oil is supplied to the interior of the protective housing 748 to ensure that the meshing parts of the bearing 4 and the gear 746 and rack 682 are always lubricated. During this process, the tank 73 continuously provides lubricating oil to the self-lubricating mechanism 7. The sealing cover 76 ensures the sealing of the tank 73 to prevent the lubricating oil inside the tank 73 from being contaminated or leaking from the outside, thus ensuring the quality of the lubricating oil. If the lubricating oil is insufficient, the sealing cover 76 can be opened again to replenish it through the oil filling pipe 75. Therefore, there is no need to frequently stop the machine to check the oil level, ensuring the continuity of the winding operation. Finally, after the anchor chain or rope winding operation is completed, the external drive equipment, drive motor 63, and solenoid valve 744 are turned off in sequence. After the external drive equipment is turned off, the winding roller 5 stops rotating, and the winding operation is completed. After the drive motor 63 is turned off, the lead screw 64 stops rotating, and the slider 65, straightening arm 66, and straightening ring 67 stop moving. After the solenoid valve 744 is closed, the auger 745 stops rotating, and the lubricating oil delivery stops. At this point, the entire winding operation and lubrication process is completed. This technical solution, by setting the reciprocating motion of the straightening ring 67, can guide the anchor chain or rope to be evenly distributed along the axial direction of the winding roller 5, effectively solving the problem of uneven winding caused by the rope easily getting tangled in one place during the winding of existing anchor winches in the background technology. At the same time, the straightening ring 67 can perform preliminary sorting on the surface of the rope during the rope guiding process, reducing some of the impurities attached to the rope and reducing the probability of impurities entering the equipment with the rope, thus alleviating the equipment contamination problem. Through the linkage between the straightening mechanism 6 and the self-lubricating mechanism 7, the automatic delivery of lubricating oil is realized, eliminating the need for manual periodic oiling, and solving the problem of existing anchor winches. The winch suffers from the problems of cumbersome manual oiling operation and high maintenance costs. The solenoid valve 744 on the oiling pipe 743, combined with the movement rhythm of the straightening mechanism 6, achieves automatic oil replenishment. Each time the straightening mechanism 6 is started, the rack 682 drives the gear 746 and the auger 745 to rotate to pump lubricating oil, ensuring that the bearing 4 receives sufficient lubrication each time it starts, avoiding excessive or insufficient lubrication, and solving the problem of difficulty in accurately controlling the amount and cycle of oiling by manual oiling. Continuous lubrication can reduce the wear of the bearing 4 caused by friction, reduce the probability of failures such as bearing 4 jamming and shaft deformation. The reduced frictional resistance of the bearing 4 can also reduce the load on the external drive system, reduce energy consumption, and solve the problems of high load and rapid component wear of the drive system. The coordinated work of various structures, such as the mounting plate 1, side plate 2, and side plate 3, constitutes a stable support system, ensuring the stable operation of the winding roller 5, the straightening mechanism 6, and the self-lubricating mechanism 7. The additional functions of each structure further improve the stability and service life of the device, and the overall anchor winch achieves efficient, stable, and low-loss winding operation. During application, before each operation, upon the first start of the straightening mechanism 6, the straightening mechanism 6 can drive the auger 745 to perform a forward downward drive pumping, thereby pumping lubricating oil once. Under normal circumstances, only one pumping of lubricating oil is needed each time it is started to achieve the lubrication effect. After one pumping is completed during use, when the rack 682 moves to the other side, the lubricating oil pumping is finished. At this time, simply close the stop solenoid valve 744. Under normal circumstances, the lubricating oil will slowly flow downward to the bottom of the oil drain pipe 742, at which point the lubricating oil enters the oil drain hopper 7. Inside the oil drain pipe 742 and the oil drain pipe 41, each time the straightening mechanism 6 is started, the straightening mechanism 6 will drive the rack 682 to drive the gear 746 to rotate, thereby driving the auger 745 to rotate downwards and pump. Each time it is started, the subsequent pumping is sufficient to meet the addition of lubricating oil. When the rack 682 resets and drives the auger 745 to rotate in the opposite direction, the lubricating oil has been pumped. Therefore, it is only necessary to close the solenoid valve 744. During the application of this device, the outer side of its guide rail 61 is equipped with a bellows cover. By setting the bellows cover, the lead screw 64 can be covered to prevent the lead screw 64 from being affected by external dust and impurities.

[0020] In this technical solution, the controller is an STM32F407 series microcontroller, installed on the top rear side of the mounting plate 1 near the support frame 71. The controller has a display screen for real-time display of equipment operating parameters. The drive motor 63 is a YE2 series three-phase asynchronous motor, model YE2-100L-4, with a rated power of 1.5-3kW, rated voltage of 380V, and rated speed of 1400-2800r / min. The motor is equipped with an E6B2-CWZ6C encoder with a resolution of 1000-2000 pulses / revolution, enabling flexible adjustment of rotation and stepless speed regulation. The motor output is connected to the lead screw 64 via a coupling, and the motor is used in conjunction with a gearbox reducer 746. The gearbox reducer 746 is an RV series worm gear reducer with a reduction ratio of 20-100, used to assist in increasing torque or regulating speed reduction. The solenoid valve 744 is a 2W... The series 2-position 2-way solenoid valve 744, model 2W-160-15, has a rated voltage of DC24V or AC220V and a working pressure of 0.1-1.0MPa. If the transmission module 68 is unsuitable for the pumping module 74 during application, a micro pump can be used to assist in oil delivery. A 12V / 24V DC micro gear pump 746 is selected, with a flow rate of 0.5-2L / min and a rated pressure of 0.2-0.5MPa. The circuit system is powered by marine DC 24V or AC 380V. The controller input is connected to the ship's power supply system via a marine circuit breaker. The controller output is connected to the inverter of the drive motor 63, the coil of the solenoid valve 744, the signal terminal of the encoder, the data line of the display screen, and the power supply terminal of the micro pump. The drive motor 63 is connected to the controller via the inverter. The controller receives the motor speed signal from the encoder and processes it via PWM. The signal controls the output frequency of the frequency converter, thereby adjusting the motor speed. The micro pump is controlled to start and stop by the high and low level signals output by the controller, ensuring that the lubricating oil is delivered as needed. One end of the coil of the solenoid valve 744 is connected to the output pin of the controller, and the other end is grounded. The controller controls the opening and closing of the solenoid valve 744 through high and low level signals. The display screen connects to the controller via an I2C or RS485 communication interface, receiving and displaying parameters such as lubricating oil level, motor speed, solenoid valve 744 status, and micro pump operating status in real time. During use, a DS18B20 can be installed inside the tank 73 according to specific application requirements. A liquid level sensor is used to monitor the lubricating oil level. Proximity sensors (model E2E-X1R5E1) are installed on both sides of the take-up roller 5 to detect the number of rotations of the take-up roller 5 to calculate the winding length. Limit switches (model ME-8108) are installed at both ends of the guide rail 61 to limit the movement of the slider 65 to prevent overtravel. A vibration sensor (model SDJ-2) is installed at the bearing 4 to monitor the operating status of the bearing 4. The signal output terminals of these sensors are all connected to the analog or digital input pins of the controller. After receiving the sensor signals, the controller processes the data. If abnormal parameters are detected (such as low lubricating oil level, excessive vibration of bearing 4, etc.), an alarm is triggered on the display screen or the control equipment is shut down. All electronic components use marine-grade waterproof wires for circuit connections, and waterproof connectors are used at the interfaces to ensure stable operation of the circuit system in humid and salt spray environments.
