Description

Technical Field

[0001] This invention belongs to the field of marine engineering technology, and in particular relates to a rapid oil draining device for intermediate bearings and its usage method. Background Technology

[0002] In certain ship propulsion systems, shaft lengths can reach tens of meters. To ensure stable system operation, designers place intermediate bearings at appropriate locations within the shaft system to support and support the intermediate shaft, ensuring its smooth operation. To guarantee the proper functioning of the intermediate bearings, an oil chamber is provided inside to store lubricating oil. Routine maintenance of these intermediate bearings has a significant impact on improving their service life and reliability.

[0003] When using intermediate bearings, regularly changing the lubricating oil in the lubrication chamber is a crucial maintenance measure, based on the ship's maintenance procedures and the actual operating condition of the intermediate bearing. Typically, oil changes are performed by draining the oil through the drain port at the bottom side of the intermediate bearing, and collecting the oil in a small bucket or similar container at the bottom.

[0004] However, due to the often confined space where intermediate bearings are located, draining the oil usually requires the cooperation of multiple people. First, a container must be secured below the drain port of the intermediate bearing to ensure smooth oil flow. Then, other operators are responsible for removing the drain plug from the drain port. When there is a large amount of oil in the lubrication chamber, the plug needs to be removed and reinstalled multiple times, and the oil draining and receiving operations need to be performed repeatedly to complete the oil change. This makes the intermediate bearing oil change process cumbersome and complex, requiring multiple people to work together, and there is a risk of oil splashing during the draining process, posing a certain safety hazard. Summary of the Invention

[0005] To address the problems existing in the prior art, the present invention aims to provide a simple, easy-to-use, low-cost, and widely applicable intermediate bearing quick oil draining device. By adjusting the angles of the connecting rod and telescopic rod, and the rotating plate and oil collection plate, the versatility of the device is improved, making it suitable for intermediate bearings of different specifications. Furthermore, the hose connected at the bottom can flexibly adjust the oil receiving position, further simplifying the operation of draining intermediate bearing oil. At the same time, by utilizing the method of using this device, single-person operation can be achieved for oil draining, avoiding multiple disassembly and assembly of the drain plug, improving efficiency, reducing lubricating oil leakage, lowering safety risks, and reducing manpower consumption.

[0036] To better understand the purpose, structure, and function of this invention, the technical solutions in the embodiments of this invention will be clearly and completely described below with reference to the accompanying drawings.

They are not intended to indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific direction, and therefore should not be construed as a limitation of this invention.

[0038] Example 1

[0039] like Figure 1 and Figure 2 As shown in the figure, this embodiment provides a quick oil draining device for intermediate bearings and its usage method. The oil draining device includes an oil collection tray 1, a draining component 2, an adjusting mechanism 3, a fixing component 4, and an auxiliary support component.

[0040] The oil collecting tray 1 is used to receive lubricating oil flowing out from the drain plug 62 of the intermediate bearing. The oil collecting tray 1 is ellipsoidal and the upper edge of the oil collecting tray 1 is elliptical, which facilitates the collection of lubricating oil and enables the oil collecting tray 1 to collect the oil discharged from the intermediate bearing more efficiently, thereby ensuring that the oil does not splash everywhere and effectively maintaining the cleanliness and tidiness of the working environment. A drain hole 11 is provided at the lowest point of the lower end of the oil collecting tray 1. The oil collecting tray 1 is fixedly connected to the drain assembly 2 through the drain hole 11. The drain assembly 2 is used to guide and control the lubricating oil to be discharged to a designated location or container.

[0041] The venting assembly 2 includes a venting valve 21, a venting pipe 22, and a hose 23. The venting valve 21 is fixedly connected to the venting hole 11 located at the lowest point of the oil collection tray 1. In this embodiment, the venting hole 11 is a threaded hole, and the upper end of the venting valve 21 is threaded onto the threaded hole. The lower end of the venting valve 21 is connected to the upper flange of the venting pipe 22, and the venting valve 21 is used to control the opening and closing of the venting pipe 22. The upper end of the hose 23 is sleeved and fixed to the lower end of the venting pipe 22, and the lower end of the hose 23 connects to a designated location or a collection container. The length of the hose 23 is determined according to the actual usage scenario and requirements, and a suitable length can be flexibly selected to adapt to different working environments. This design flexibility allows the discharged lubricating oil to be effectively guided to a predetermined location or collection container, preventing the oil from spreading disorderly in the workplace, thus avoiding pollution of the working environment, maintaining the cleanliness and safety of the workplace, and making the entire operation process more efficient, safe, and environmentally friendly.

[0042] The adjustment mechanism 3 is symmetrically arranged on the left and right sides of the oil collection plate 1, and the front end of the adjustment mechanism 3 is movably connected to the upper edge of the side wall of the oil collection plate 1 near the rear end through the first hinge, so that the adjustment mechanism 3 can rotate along the central axis of the first hinge and flip relative to the upper edge of the oil collection plate 1.

[0043] The front end of the fixing component 4 is fixed with a universal joint 411. The rear end of the adjusting mechanism 3 is movably connected to the front end of the fixing component 4 through the universal joint 411, so that the fixing component 4 can rotate freely around the universal joint 411 to adjust the angle, thereby adjusting the position of the rear end of the fixing component 4. The rear end of the fixing component 4 is used to be fixedly connected to the lifting hole 61 on the intermediate bearing.

[0044] The auxiliary support members are symmetrically arranged on the left and right sides of the oil collection plate 1, and the rear end of the auxiliary support member is movably connected to the upper edge of the side wall of the oil collection plate 1 near the rear end through the second hinge member, so that the auxiliary support member can rotate around the central axis of the second hinge member and the front end of the auxiliary support member extends to the left and right sides of the oil collection plate 1.

[0045] In this embodiment, the adjusting mechanism 3 includes a telescopic rod 31 and a rotating plate 32. The telescopic rod 31 includes at least three cylindrical support rods, which are connected in pairs to form a telescopic structure. The rotating plate 32 has a certain thickness. The fixing component 4 includes a connecting rod 41 and a fastener. The connecting rod 41 adopts a screw structure, and the fastener adopts a locking nut 42. The auxiliary support component adopts a support rod 5. The first hinge component adopts a first pin 7, and the second hinge component adopts a second pin 8.

[0046] The upper edge of the oil collecting plate 1 is provided with an adjustment and positioning groove. A transverse hole is provided on each of the front and rear side walls of the adjustment and positioning groove. The first pin 7 passes through the front and rear end faces of the rotating plate 32 laterally, and the two ends of the first pin 7 are respectively installed in the transverse holes on the side walls of the adjustment and positioning groove, so that the rotating plate 32 is hinged and fixed to the oil collecting plate 1. The length of the adjustment and positioning groove is greater than the length of the rotating plate 32, and the depth of the adjustment and positioning groove is greater than the depth to which the lower end of the rotating plate 32 is embedded in the oil collecting plate 1, thereby ensuring that the rotating plate 32 will not interfere with the oil collecting plate 1 during the rotation operation, thus ensuring the smoothness of the rotation and the stability of the device installation.

[0047] The front end of the telescopic rod 31 is welded and fixed to the rotating plate 32. The universal joint 411 is provided at the rear end of the telescopic rod 31. The rear end of the telescopic rod 31 is movably connected to the front end of the connecting rod 41 through the universal joint 411. The rear end of the connecting rod 41 passes through the lifting hole 61 and is threadedly connected to the locking nut 42, thereby fixing the oil draining device on the intermediate bearing. The telescopic rod 31 and the rotating plate 32 allow for flexible adjustment of the rear end position of the connecting rod 41 and the center distance between the two connecting rods 41. Furthermore, the universal joint 411's ability to rotate and tilt further ensures the flexibility and stability of the adjustment mechanism 3 during connection adjustments. It allows the connecting rod 41 to rotate and swing freely in multiple directions, adapting to different positions and angles on intermediate bearings of varying sizes and shapes in the lifting hole 61. This ensures that the adjusted rear end of the connecting rod 41 can be smoothly inserted into the lifting hole 61. This not only ensures the stability and reliability of the device but also significantly improves the flexibility and applicability of the adjustment mechanism 3 in actual operation, enhancing the flexibility of the device and simplifying the installation process on the intermediate bearing.

[0048] The upper edge of the oil collecting pan 1 is also provided with a support positioning groove. A longitudinal hole is provided at the bottom of the support positioning groove near one side of the groove wall. The lower end of the second pin 8 is installed in the longitudinal hole. The second pin 8 extends longitudinally through the upper and lower end faces of the support rod 5. A limit member is fixed to the upper end of the second pin 8 that protrudes from the upper end face of the support rod 5, so that the support rod 5 is hinged and fixed to the oil collecting pan 1.

[0049] The connection length between the support rod 5 and the oil collection tray 1 via the first shaft pin is less than the connection length between the rotating plate 32 and the oil collection tray 1 via the second shaft pin. This allows the rotating plate 32 to provide primary support, while the support rod 5 provides only auxiliary support. Therefore, in actual operation, the support method for the oil collection tray 1 can be flexibly selected based on the amount of oil drained. When the amount of drained lubricating oil is small, using only the rotating plate 32 as support for the oil collection tray 1 is sufficient. When the amount of drained lubricating oil is large, the support rod 5 is deployed as auxiliary support for the oil collection tray 1. This not only improves the flexibility of the draining operation, adapting to the draining and maintenance operations of intermediate bearings in various narrow spaces, but also ensures the overall stability and reliability of the draining device under different operating conditions.

[0050] Example 2

[0051] like Figures 1 to 3 As shown, this embodiment provides a method for using the intermediate bearing quick oil draining device of Embodiment 1, including the following steps:

[0052] S1. Measure the center distance L1 of the lifting holes 61 on both sides of the intermediate bearing, and simultaneously adjust the rotation angle of the rotating plates 32 on both sides of the oil draining device so that the center distance of the two connecting rods 41 is the same as the measured center distance L1 of the lifting holes 61 on both sides.

[0053] S2. After the center distance of the two connecting rods 41 is adjusted, the two connecting rods 41 are inserted into the corresponding lifting holes 61 on both sides of the intermediate bearing. Then, a locking nut 42 is installed on the outer end of the connecting rod 41 that passes through the lifting hole 61. By tightening the locking nut 42, the connecting rod 41 is locked and fixed to the lifting hole 61 of the intermediate bearing, thereby fixing the oil draining device on the intermediate bearing.

[0054] S3. By synchronously adjusting the length of the telescopic rod 31, the angle of the universal joint 411 between the telescopic rod 31 and the connecting rod 41, and the rotation angle of the rotating plate 32 relative to the oil collection plate 1, the height of the oil collection plate 1 and the position of the oil collection plate 1 relative to the intermediate bearing are adjusted until the oil collection plate 1 is located at the bottom of the intermediate bearing, ensuring that the drain plug 62 on the intermediate bearing is located directly above the oil collection plate 1, so that during the oil draining operation, the lubricating oil can be effectively prevented from flowing out of the oil collection plate 1.

[0055] S4. Check the drain valve 21 at the bottom of the oil collection pan 1 to ensure that the drain valve 21 is closed; then open the drain plug 62 at the bottom of the intermediate bearing to allow lubricating oil to flow into the oil collection pan 1.

[0056] S5. Check and ensure that the upper end of the hose 23 is securely connected to the outlet of the drain pipe 22 on the oil collection tray 1, and connect the lower end of the hose 23 to the designated drain position or collection container. Open the drain valve 21 until all the lubricating oil in the intermediate bearing is drained through the drain device.

[0057] S6. After draining the oil, close the drain plug 62 located at the bottom of the intermediate bearing, remove the draining device, and the entire draining process is complete.

[0058] When the amount of lubricating oil to be drained is large, the following steps are included between steps S3 and S4: rotating the support rods 5 located on both sides of the oil collection pan 1 and mounting the support rods 5 on the nearby hull structure. In this embodiment, after the support rods 5 are unfolded, they are mounted on the adjacent intermediate bearing base to provide support for the oil collection pan 1, ensuring the stability of the oil collection pan 1 during the oil draining operation and effectively avoiding tilting or collapse caused by the excessive weight of the oil collection pan 1; wherein, the amount of lubricating oil to be drained can be obtained according to the specifications of the intermediate bearing.

[0059] The above description is merely a preferred embodiment of the present invention and is not intended to limit the invention. Those skilled in the art can make various changes or equivalent substitutions to these features and embodiments without departing from the spirit and scope of the invention. Furthermore, under the teachings of this invention, these features and embodiments can be modified to adapt to specific situations and materials without departing from the spirit and scope of the invention. Therefore, the present invention is not limited to the specific embodiments disclosed herein, and all embodiments falling within the scope of the claims of this application are protected by this invention.
