Description

Technical Field

[0001] This utility model relates to the technical field of cantilever beam lubrication systems, specifically an alternating lubricating oil filter assembly based on a cantilever beam sliding system. Background Technology

[0002] The lubrication system of a jack-up drilling platform's cantilever beam skid system, as a core subsystem ensuring efficient equipment operation, generally employs a circulating lubricating oil mode to cope with the challenges of high salt spray, high humidity, and frequent mechanical wear in the marine environment. In this system, the lubricating oil needs to undergo multi-stage filtration to remove metal debris (such as iron and copper particles) and contaminants (such as silt and colloidal deposits), thereby reducing the wear rate of key components such as the skid rails, hydraulic cylinders, and gearboxes, and extending the overall service life of the equipment. In existing technologies, lubricating oil filtration typically employs a graded treatment process: coarse filtration stage: using a metal filter screen to intercept larger particles and construction residues; fine filtration stage: using a polymer material filter element for deep purification to ensure that the oil cleanliness meets or exceeds the requirements of ISO 4406 standards 18 / 16 / 13.

[0003] However, in practical applications, the metal filter screen in the coarse filtration stage is prone to rapid clogging due to long-term exposure to highly polluted environments (such as drilling mud infiltration and metal wear debris accumulation). Specifically, this manifests as: flow rate reduction: filter screen clogging leads to increased oil circuit pressure differential, resulting in a 30%-50% decrease in system flow rate; shutdown maintenance: traditional flushing methods require cutting off the lubrication system's oil supply circuit, disassembling the filter screen for high-pressure water jet backwashing or chemical solvent soaking, with each maintenance session taking 2-4 hours, causing platform operation interruption; secondary pollution risk: manual disassembly and assembly may introduce external pollutants, exacerbating the deterioration of system cleanliness.

At the same time, the alternating operation can also facilitate online backwashing of filters when they are not in operation without interrupting the operation.

Detailed Implementation

[0017] 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.

[0018] Please see Figure 1-3 This utility model provides a technical solution: an alternating lubricating oil filter pipe assembly based on a cantilever beam sliding system, including a parallel pipe 1, one end of the parallel pipe 1 is provided with an oil inlet pipe 2, and the other end of the parallel pipe 1 is provided with an oil outlet pipe 3. Two filters are provided on the parallel pipe 1. Externally returned lubricating oil enters the oil inlet pipe 2, is filtered by one of the filters, and then flows back to the oil tank through the oil outlet pipe 3.

[0019] The filter includes a spherical shell 4 installed on a parallel pipeline 1. A spherical valve core 5 is rotatably installed inside the spherical shell 4. The spherical valve core 5 has an installation hole inside, allowing lubricating oil in the parallel pipeline 1 to flow through the installation hole. A filter screen 51 is provided on the side of the installation hole near its outlet end. A flushing pipe is provided on the top of the spherical shell 4, and a drain pipe 9 is provided at the bottom of the spherical shell 4 corresponding to the flushing pipe. A geared motor 41 is provided on the side of the spherical shell 4 to drive the spherical valve core 5 to rotate. The geared motor 41 can drive the spherical valve core 5 to rotate, which facilitates the flushing pipe to flush the filter screen 51.

[0020] Furthermore, an oil inlet three-way valve 21 is provided at the connection between the oil inlet pipe 2 and the parallel pipeline 1 to facilitate control of the flow direction of the lubricating oil.

[0021] Furthermore, an oil outlet three-way valve 31 is provided at the connection between the oil outlet pipe 3 and the parallel pipeline 1.

[0022] Furthermore, the flushing fitting includes a flushing pipe 6 connecting two spherical shells 4. The flushing pipe 6 is provided with a water outlet pipe 7 and a water outlet valve 71. When the water outlet valve 71 is opened, the water outlet pipe 7 is connected to an external high-pressure water pipe. The external high-pressure water backwashes the filter screen 51 through the water outlet pipe 7 and the flushing pipe 6, and discharges the sewage containing impurities through the drain pipe 9.

[0023] Furthermore, the flushing pipe 6 is also equipped with an air outlet pipe 8, which is equipped with an air outlet valve 81. When the air outlet valve 81 is opened, the air outlet pipe 8 is connected to an external air compressor, and the high-pressure air washes and dries the filter screen 51 again.

[0024] Furthermore, a sealing ring 52 is provided on the peripheral side of the spherical valve core 5, which can improve the sealing between the ball shell 4 and the spherical valve core 5.

[0025] The oil inlet three-way valve 21, oil outlet three-way valve 31, geared motor 41, water outlet valve 71, and air outlet valve 81 used in this utility model are all common electrical components in the prior art. Their working methods and circuit structures are well-known technologies and will not be described in detail here. Furthermore, the oil inlet three-way valve 21, oil outlet three-way valve 31, water outlet valve 71, and air outlet valve 81 all adopt solenoid valves commonly used in this field.

[0026] When using:

[0027] by Figure 3 For example, under normal circumstances, the returned lubricating oil enters the oil inlet pipe 2. The lubricating oil in the oil inlet pipe 2 is filtered by the filter on the left side of the parallel pipeline 1 and then flows back to the oil tank through the oil outlet pipe 3.

[0028] When the filter on the left is blocked, control the inlet three-way valve 21 and the outlet three-way valve 31 to work, so that the lubricating oil is filtered through the filter on the right side of the parallel pipeline 1 and flows back to the oil tank through the outlet pipe 3.

[0029] At the same time, the left-side geared motor 41 is controlled to work, and the left-side geared motor 41 drives the corresponding ball valve core 5 to rotate 90 degrees, and makes the oil outlet end of the mounting hole in the ball valve core 5 face upward and the oil inlet end face downward.

[0030] Open the water outlet valve 71, and external high-pressure water backwashes the filter screen 51 through the water outlet pipe 7 and the flushing pipe 6, and discharges the sewage containing impurities through the drain pipe 9.

[0031] After rinsing for a period of time, close the water outlet valve 71 and open the air outlet valve 81. High-pressure air will rinse and dry the filter screen 51 again.

[0032] After the filter screen 51 is rinsed, the corresponding reduction motor 41 is controlled to work, and the reduction motor 41 drives the ball valve core 5 to reset.

[0033] This invention employs a parallel and alternating filtration method to ensure that one filter is working stably at all times, thereby ensuring stable oil pressure. At the same time, the alternating operation also allows for convenient online backwashing of filters when they are not in operation, without interrupting the operation. It also avoids the introduction of external contaminants and is easy to use.

[0034] The parts not disclosed in this utility model are all prior art, and their specific structures, materials, and working principles will not be described in detail. Although embodiments of this utility model have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of this utility model, the scope of which is defined by the appended claims and their equivalents.
