Description

Technical Field

[0001] The present invention relates to the technical field of ship gearboxes, and in particular to a mooring machine gearbox. Background Art

[0002] Bulk carriers are vessels designed specifically to transport large quantities of dry bulk cargo (such as coal, ore, grain, and cement). They are characterized by a single-deck structure, direct stowage of unpackaged cargo, and cargo hold designs tailored to the physical characteristics of the cargo (such as volume and fluidity). Because cargo requires no packaging, bulk carriers eliminate the compartments typically found in general cargo ships, resulting in greater cargo capacity and improved loading and unloading efficiency. A bulk carrier's mooring winch gearbox is a core component of the ship's deck machinery, primarily responsible for controlling the retraction and tensioning of the mooring rope, ensuring stability during berthing, mooring, and navigation.

[0003] When the gearbox is insufficiently lubricated, an effective oil film cannot be formed at key locations, resulting in wear and tear, which in turn reduces transmission efficiency. Poor lubrication will lead to additional energy consumption costs. In severe cases, it may cause gear breakage or bearing seizure, which in turn causes the mooring winch to lose control and threaten the safety of deck operations. Manual lubrication is based on experience, and each lubrication requires a long downtime. The annual accumulated downtime is long, affecting the turnover efficiency of the ship. Dedicated personnel are required to operate regularly, which increases labor costs. Summary of the Invention

The lubrication mechanism works regularly to deliver lubricating oil to the key parts of the gearbox, automatically lubricating the key parts of the gearbox instead of manual lubrication. It can automatically adjust the temperature to ensure that the temperature of the lubricating oil is always within the optimal range. The filter component filters out solid particle contaminants in the lubricating oil to ensure the cleanliness of the lubricating oil. The material is easy to configure and the cost is low. The actual processing and production cycle of the gearbox is short, which solves the technical problems mentioned in the background technology.

Before the lubricating oil enters the lubricating oil channel of the gearbox, the lubricating oil passes through the filter assembly on the oil path and is filtered and impurities are removed by the filter assembly.

[0008] In one possible implementation, the other end of the central tube is connected to a second oil pipe, on which a pressure sensor is installed. The second oil pipe is connected to the lubricating oil channel of the gearbox through a pipeline.

[0010] In one possible implementation, a base is provided at the bottom of the cylinder, and the base is fixedly connected to the cylinder by threads.

The lubricating oil after heat exchange enters the oil return pipe and flows back to the oil pan through the return pipe, completing a cycle.

[0015] Compared with the prior art, the present invention has the following beneficial effects: The present invention adds a lubrication mechanism at the bottom of the gearbox. The lubricating oil for lubricating the gearbox is stored in the oil pan of the lubrication mechanism.

DETAILED DESCRIPTION

[0022] The embodiment of the present application provides a mooring machine gearbox, adds a lubrication mechanism at the bottom of the gearbox, and the lubrication mechanism works regularly to deliver lubricating oil to the key parts of the gearbox, automatically lubricating the key parts of the gearbox instead of manual lubrication. It can automatically adjust the temperature to ensure that the temperature of the lubricating oil is always within the optimal range. The filter component filters out solid particle contaminants in the lubricating oil to ensure the cleanliness of the lubricating oil. The material is easy to configure and the cost is low. The actual processing and manufacturing cycle of the gearbox is short, thereby solving the technical problems mentioned in the background technology.

[0023] The technical solution in the embodiments of the present application is to solve the problems of the above-mentioned background technology, and the overall idea is as follows: Example 1: See also Figure 1-11 The present invention provides a technical solution: a mooring machine gearbox, comprising a gearbox 1, a gearbox cover 2 and a lubricating mechanism 3, the gearbox cover 2 is installed at the top of the gearbox 1, and the lubricating mechanism 3 is installed at the bottom of the gearbox 1, the lubricating mechanism 3 comprises an oil pan 31, one side of the oil pan 31 is provided with a first oil pump 32, a filter assembly 34, an oil level sensor 38 and an oil replenishing pipe 39, the other side of the oil pan 31 is provided with a second oil pump 36 and a heat exchange assembly 37, a temperature sensor 35 is installed on the side of the oil pan 31, both ends of the first oil pump 32 are connected to a first oil pipe 33, one group of first oil pipes 33 is embedded in the oil pan 31, and the other group of first oil pipes 33 is connected to the filter assembly 34, the gearbox 1 comprises a lubricating oil channel, and the filter assembly 34 is connected to the lubricating oil channel of the gearbox 1 through a pipeline.

[0024] The lubricating oil for lubricating the gearbox 1 is stored in the oil pan 31 of the lubricating mechanism 3. The lubricating mechanism 3 works regularly to deliver lubricating oil to the key parts of the gearbox 1, automatically lubricating the key parts of the gearbox 1 instead of manual lubrication, reducing downtime, and being able to automatically adjust the flow of lubricating oil to avoid excessive waste of lubricating oil in traditional manual lubrication. The lubricating oil is delivered to the lubricating oil channel of the gearbox 1 through the lubricating mechanism 3, and then diverted to various key parts through the lubricating oil channel of the gearbox 1 to ensure that the lubricating oil accurately covers key areas such as the gear meshing surface and the bearing raceway, thereby improving the oil film coverage rate and thus improving the lubrication quality. The oil pan 31 is set at the bottom of the gearbox 1, and the excess lubricating oil will flow back to the oil pan 31 under the action of gravity and be reused, so as to avoid waste caused by excessive filling of lubricating oil.

[0025] The probe of the oil level sensor 38 extends into the oil to monitor the oil level of the lubricating oil in the oil pan 31 in real time. The oil replenishing pipe 39 is connected to the oil replenishing system. The oil replenishing system includes an oil storage tank and a pump body. When the lubricating oil in the oil pan 31 is insufficient, the oil level sensor 38 collects the oil level data in real time and transmits it to the controller through the digital bus. The controller determines whether the oil replenishing condition is triggered. If triggered, the pump body is turned on to transport the lubricating oil to the oil pan 31 through the pipeline to achieve oil replenishment. The flow meter accumulates the oil replenishment amount and closes the actuator when the upper limit or the preset oil replenishment amount is reached. The oil level sensor 38 cooperates with the oil replenishing system to realize automatic oil replenishment of the lubricating mechanism 3 without manual oil replenishment.

[0026] The temperature of the lubricating oil in the oil pan 31 is monitored in real time by the temperature sensor 35, and the oil temperature data is collected. The PLC converts the analog signal into a digital value to determine whether the temperature exceeds the preset upper limit. When the oil temperature is too high, the actuator is driven to cool the lubricating oil to ensure that the temperature of the lubricating oil is always within the optimal range to avoid the occurrence of insufficient oil film thickness due to excessively high oil temperature. An electric heating pipe assembly can be added to the oil pan 31. In cold weather, the lubricating oil can be heated by the electric heating pipe assembly to bring its temperature to the optimal temperature range to meet lubrication requirements.

[0027] In some examples, mounting lugs 311 are provided at the corners of the upper end surface of the oil pan 31 , mounting holes are provided on the mounting lugs 311 , and the oil pan 31 is fixedly connected to the gearbox 1 by bolts.

[0028] The oil pan 31 is detachably connected to the gearbox 1 , which makes it easy to install and remove the oil pan 31 and replace the lubricating oil. The oil pan 31 can be removed separately for cleaning, or replaced separately, which is convenient for maintenance.

[0029] In some examples, the filter assembly 34 includes a cylinder 341, which has a filter cartridge 342 built in it. The filter cartridge 342 includes a filter layer. A center tube 343 is provided on the cylinder 341. One end of the center tube 343 extends into the cylinder 341. The filter cartridge 342 is covered on the outside of the center tube 343. An annular flow channel is formed between the filter cartridge 342 and the inner wall of the cylinder 341.

[0030] Before the lubricating oil enters the lubricating oil channel of the gearbox 1, it passes through the filter assembly 34 on the oil channel and is filtered and cleaned by the filter assembly 34 to remove solid particle contaminants, prevent mechanical wear and failure, and avoid oil channel blockage. If contaminants enter key areas such as the gear meshing surface and the bearing raceway, they will destroy the integrity of the lubricating oil film in key positions, thereby causing friction failure. In the process of reusing the lubricating oil, the solid particle contaminants in the lubricating oil are filtered out by the filter assembly 34 on the oil channel to ensure the cleanliness of the lubricating oil and improve the lubrication quality.

[0031] like Figure 11 As shown, the lubricating oil, driven by the first oil pump 32, enters the annular flow channel of the cylinder 341 through the first oil pipe 33, and the solid particulate contaminants in the lubricating oil are intercepted by the filter layer of the filter cylinder 342. The lubricating oil is filtered and impurities are removed by the filter layer of the filter cylinder 342. The lubricating oil after filtering and impurities removal enters the central pipe 343 and enters the second oil pipe 344 through the central pipe 343.

[0032] In some examples, the other end of the central tube 343 is connected to a second oil delivery pipe 344 , on which a pressure sensor 345 is installed. The second oil delivery pipe 344 is connected to a lubricating oil passage of the gearbox 1 through a pipeline.

[0033] The pressure at the oil outlet of the filter assembly 34 is monitored in real time through the pressure sensor 345. When the filter cartridge 342 is not blocked, the pressure difference between the inside and outside of the filter assembly 34 is stable, and the ratio of the oil outlet pressure to the oil inlet pressure is close to 1. When the filter cartridge 342 is blocked, the oil flow resistance will increase sharply and the oil outlet pressure will drop significantly. The pressure sensor 345 outputs a signal to the PLC, and the value fed back by the pressure sensor 345 is used to determine whether the filter cartridge 342 is blocked, so that the filter cartridge 342 can be replaced and cleaned in time.

[0034] In some examples, a connecting seat 347 is provided inside the cylinder 341, and the filter cartridge 342 and the connecting seat 347 are threadedly fixedly connected. The filter cartridge 342 and the connecting seat 347 are detachably connected. By applying a certain external force to rotate the filter cartridge 342, the filter cartridge 342 can be disassembled, making it convenient to replace the filter cartridge 342.

[0035] In some examples, a base 346 is provided at the bottom of the cylinder 341, and the base 346 and the cylinder 341 are fixedly connected by threads. The base 346 and the cylinder 341 are detachably connected. By applying a certain external force to rotate the base 346, the base 346 can be disassembled. When the filter cartridge 342 needs to be replaced, the base 346 at the bottom of the cylinder 341 is first removed, and then the filter cartridge 342 is removed. After cleaning or replacing the new filter cartridge 342, the base 346 is reinstalled, which makes the installation and disassembly of the filter cartridge 342 convenient and facilitates maintenance.

[0036] In some examples, a small bearing hole 11 and a large bearing hole 12 are provided on the gearbox 1, and a mounting base 13 is provided at the bottom of the gearbox 1. The large bearing hole 12 is used to fix the large gear shaft of the cable machine, and the small bearing hole 11 is used to fix the small gear shaft of the motor.

[0037] By adopting the above technical solutions: A lubrication mechanism 3 is added to the bottom of the gearbox 1. The lubricating oil for lubricating the gearbox 1 is stored in an oil pan 31 of the lubrication mechanism 3. The lubrication mechanism 3 works regularly to deliver lubricating oil to key parts of the gearbox 1. The key parts of the gearbox 1 are automatically lubricated instead of manual lubrication, which reduces downtime. The lubricating oil flow rate can be automatically adjusted to avoid excessive waste of lubricating oil in traditional manual lubrication. The lubricating oil is delivered to the lubricating oil channel of the gearbox 1 through the lubrication mechanism 3, and then diverted to various key parts through the lubricating oil channel of the gearbox 1, ensuring that the lubricating oil accurately covers key areas such as the gear meshing surface and the bearing raceway, thereby improving the oil film coverage rate and thus improving the lubrication quality.

[0038] The temperature of the lubricating oil in the oil pan 31 is monitored in real time by the temperature sensor 35, and the oil temperature data is collected. When the oil temperature is too high, the actuator is driven to cool the lubricating oil to ensure that the temperature of the lubricating oil is always within the optimal range, avoiding the occurrence of insufficient oil film thickness due to excessively high oil temperature. The oil level sensor 38 collects oil level data in real time. The oil level sensor 38 cooperates with the oil replenishment system to realize automatic oil replenishment of the lubricating mechanism 3 without manual oil replenishment.

[0039] Before the lubricating oil enters the lubricating oil passage of the gearbox 1, it passes through the filter assembly 34 on the oil passage, where it is filtered to remove impurities and solid particle contaminants, thereby preventing mechanical wear and failure and avoiding blockage of the oil passage. During the reuse of the lubricating oil, the filter assembly 34 on the oil passage removes solid particle contaminants from the lubricating oil, thereby ensuring the cleanliness of the lubricating oil and improving the lubrication quality.

[0040] The material used in manufacturing the gearbox 1 is the commonly used Q235A steel plate, which is easy to configure and has low cost. The actual processing and manufacturing cycle of the gearbox 1 is short, which meets the requirements of the ship repair manufacturing cycle.

[0041] Example 2: Based on Example 1, this example introduces a specific structure of a heat exchange component 37 in a mooring machine gearbox. The heat exchange component 37 is fixedly connected to the oil pan 31 through a mounting frame 376. The heat exchange component 37 includes a frame 371, a heat exchange bend 372 and heat exchange fins 373. Multiple groups of heat exchange fins 373 increase the heat transfer area. Multiple groups of heat exchange fins 373 are mounted on the heat exchange bend 372. Multiple groups of heat exchange fins 373 are evenly spaced along the axial direction of the heat exchange bend 372.

[0042] The temperature of the lubricating oil in the oil pan 31 is monitored in real time by the temperature sensor 35, and the oil temperature data is collected. The PLC converts the analog signal into a digital value to determine whether the temperature exceeds the preset upper limit. When the oil temperature is too high, the second oil pump 36 works to extract the lubricating oil inside the oil pan 31 and transport it to the heat exchange elbow 372 of the heat exchange component 37. The heat flows in the heat exchange elbow 372, and the heat is conducted to the multiple groups of heat exchange fins 373 through the pipe wall. The multiple groups of heat exchange fins 373 then exchange heat with the surrounding air. The second oil pump 36 drives the lubricating oil in the oil pan 31 to circulate, thereby cooling the lubricating oil until the lubricating oil is cooled to a specified temperature range, and then put it into use to ensure the lubrication effect.

[0043] In some examples, a mounting hole is opened on the frame 371, and the frame 371 and the mounting frame 376 are fixedly connected by bolts. The heat exchange component 37 is detachably connected, which facilitates the installation and disassembly of the heat exchange component 37 and facilitates maintenance.

[0044] In some examples, one end of the heat exchange elbow 372 is connected to the oil inlet pipe 374, and the other end of the heat exchange elbow 372 is connected to the oil return pipe 375. One end of the second oil pump 36 is connected to the oil inlet pipe 374, one end of the return oil pipe 375 is connected to the heat exchange elbow 372, and the other end of the return oil pipe 375 is embedded in the oil pan 31.

[0045] When the second oil pump 36 is working, the lubricating oil inside the oil pan 31 is pumped out through the pipeline, the lubricating oil enters the oil inlet pipe 374, enters the heat exchange elbow 372 through the oil inlet pipe 374, and flows in the heat exchange elbow 372. The lubricating oil after heat exchange enters the return oil pipe 375 and flows back to the oil pan 31 through the return oil pipe 375, completing a cycle.

[0046] Finally, it should be noted that the above embodiments are merely examples for the purpose of illustrating the present invention and are not intended to limit the embodiments. Those skilled in the art will readily appreciate that other variations or modifications based on the above description are possible. It is not necessary and impossible to provide an exhaustive list of all embodiments. However, obvious variations or modifications arising therefrom remain within the scope of protection of the present invention.
