Description

Technical Field

[0001] The invention belongs to the technical field of ship engineering, and in particular relates to a quick oil discharge device for an intermediate bearing and a use method thereof. Background Art

[0002] In certain types of ship propulsion systems, the shaft length can reach tens of meters. To ensure the stable operation of the system, the designer configures an intermediate bearing at an appropriate position of the shaft to support the intermediate shaft to ensure the smooth operation of the intermediate shaft. To ensure the normal operation of the intermediate bearing, an oil cavity is provided inside the intermediate bearing to store oil to lubricate the bearing. The daily maintenance of the intermediate bearing has an important impact on improving the service life and reliability.

[0003] When the intermediate bearing is in use, according to the ship maintenance regulations and the actual operating conditions of the intermediate bearing, it is a vital maintenance measure to regularly replace the lubricating oil in the lubricating oil cavity. Usually, the oil change operation is mainly drained through the oil drain port at the bottom of the side of the intermediate bearing, and the oil is collected in a collection container such as a small bucket at the bottom.

[0004] However, since the intermediate bearing is often located in a small space, the oil draining operation usually requires the collaboration of multiple people. First, the container must be fixed below the oil drain port of the intermediate bearing to ensure that the lubricating oil flows smoothly into the container, and then other operators are responsible for removing the drain plug of the oil drain port; when the amount of lubricating oil in the lubricating oil cavity is large, it is necessary to disassemble and install the plug multiple times, and drain and connect the oil multiple times to complete the oil change. This makes the intermediate bearing oil change operation process cumbersome and complicated, not only requiring the collaboration of multiple people, but also the oil is prone to splashing during the oil draining process, which poses certain safety hazards.

[0036] In order to better understand the purpose, structure and function of the present invention, the technical scheme in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0038] Example 1

[0039] like Figure 1 and Figure 2 As shown, this embodiment provides a quick oil discharge device for an intermediate bearing and a method for using the same. The oil discharge device includes an oil collecting pan 1, a discharge assembly 2, an adjustment mechanism 3, a fixing assembly 4 and an auxiliary support member.

[0040] The oil collecting pan 1 is used to receive the lubricating oil flowing out from the discharge screw plug 62 of the intermediate bearing; the oil collecting pan 1 is ellipsoidal and the upper edge of the oil collecting pan 1 is elliptical, which is convenient for collecting the lubricating oil, so that the oil collecting pan 1 can more efficiently collect the oil discharged from the intermediate bearing, thereby ensuring that the oil will not splash everywhere, effectively maintaining the cleanliness and tidiness of the working environment; a discharge hole 11 is opened at the lowest point of the lower end of the oil collecting pan 1, and the oil collecting pan 1 is fixedly connected to the discharge component 2 through the discharge hole 11, and the discharge component 2 is used to guide and control the discharge of the lubricating oil to a designated position or container.

[0041] The discharge assembly 2 includes a discharge valve 21, a discharge pipe 22 and a hose 23. The discharge valve 21 is fixedly connected to the discharge hole 11 located at the lowest point of the lower end of the oil collecting pan 1; in this embodiment, the discharge hole 11 is a threaded hole, and the upper end of the discharge valve 21 is threadedly connected to the threaded hole. The lower end of the discharge valve 21 is flange-connected to the upper end of the discharge pipe 22, and the discharge valve 21 is used to control the on and off of the discharge pipe 22. The upper end of the hose 23 is sleeved and fixed on the lower end port of the discharge pipe 22, and the lower end of the hose 23 is connected to a designated position or a collection container. The length of the hose 23 is determined according to the actual use scenario and use requirements, and the appropriate length can be flexibly selected to adapt to different working environments; through the flexibility of this design, the discharged lubricating oil can be effectively guided to a predetermined position or a collection container to prevent the oil from being scattered in the workplace, thereby avoiding pollution to 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 adjusting mechanism 3 is symmetrically arranged on the left and right sides of the oil collecting pan 1, and the front end of the adjusting mechanism 3 is movably connected to the upper edge position of the center of the side wall of the oil collecting pan 1 near the rear end through a first hinge, so that the adjusting mechanism 3 can rotate along the central axis of the first hinge and flip relative to the upper edge of the oil collecting pan 1.

[0043] A universal joint 411 is fixed to the front end of the fixing component 4, and 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 freely rotate around the universal joint 411 to adjust the angle, thereby adjusting the rear end position of the fixing component 4, and 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 is symmetrically arranged on the left and right sides of the oil collecting pan 1, and the rear end of the auxiliary support is movably connected to the upper edge position of the center of the side wall of the oil collecting pan 1 near the rear end through a second hinge, so that the auxiliary support can rotate around the central axis of the second hinge and the front end of the auxiliary support can be expanded to the left and right outer sides of the oil collecting pan 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, and the cylindrical support rods are connected in pairs to form a telescopic structure, and the rotating plate 32 has a certain thickness; the fixing assembly 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 member adopts a support rod 5; the first hinge adopts a first pin 7, and the second hinge adopts a second pin 8.

[0046] The upper edge of the oil collecting pan 1 is provided with an adjusting positioning groove, and a transverse hole is provided on the groove walls on the front and rear sides of the adjusting positioning groove respectively. The first pin shaft 7 transversely penetrates the front and rear end faces of the rotating plate 32, and the two ends of the first pin shaft 7 are respectively installed in the transverse holes on the groove walls on both sides of the adjusting positioning groove, so that the rotating plate 32 is hinged and fixed on the oil collecting pan 1; the length of the adjusting positioning groove is greater than the length of the rotating plate 32, and the depth of the adjusting positioning groove is greater than the depth of the lower end of the rotating plate 32 embedded in the oil collecting pan 1, thereby ensuring that the rotating plate 32 will not interfere with the oil collecting pan 1 during the rotation operation, thereby 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 on the rotating plate 32, and the universal joint 411 is set 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 with the locking nut 42, so as to fix the oil drain device on the intermediate bearing. Through the telescopic rod 31 and the rotating plate 32, the rear end position of the connecting rod 41 and the center distance of the connecting rods 41 on both sides can be flexibly adjusted. At the same time, since the universal joint 411 has the functions of free rotation and tilt, the flexibility and stability of the adjustment mechanism 3 during connection adjustment can be further ensured, and the connecting rod 41 can be allowed to rotate and swing freely in multiple directions, so as to adapt to the different positions and angles of the lifting hole 61 on the intermediate bearings of different sizes and shapes, and ensure the horizontality of the rear end of the connecting rod 41 after adjustment. It can be smoothly inserted into the lifting hole 61, which not only ensures the stability and reliability of the device, but also significantly improves the flexibility and scope of application of the adjustment mechanism 3 in actual operation, enhances the flexibility of the use of the device, and simplifies the installation process steps of the device on the intermediate bearing.

[0048] The upper edge of the oil collecting pan 1 is also provided with a supporting positioning groove, and a longitudinal hole is provided at the bottom of the supporting positioning groove near the groove wall on one side, and the lower end of the second pin shaft 8 is installed in the longitudinal hole, and the second pin shaft 8 longitudinally penetrates the upper and lower end surfaces of the support rod 5, and a limiting piece is fixed on the upper end of the second pin shaft 8 exposed on the upper end surface of the support rod 5, so that the support rod 5 is hingedly fixed to the oil collecting pan 1.

[0049] The connection length of the support rod 5 with the oil collecting pan 1 through the first shaft pin is shorter than the connection length of the rotating plate 32 with the oil collecting pan 1 through the second shaft pin, so that the rotating plate 32 plays a main supporting role, and the support rod 5 only plays an auxiliary supporting role. Therefore, in actual operation, according to the amount of oil discharged, the support method of the oil collecting pan 1 can be flexibly selected. When the amount of lubricating oil discharged is small, it is sufficient to use only the rotating plate 32 as the support of the oil collecting pan 1; when the amount of lubricating oil discharged is large, the support rod 5 is deployed as an auxiliary support for the oil collecting pan 1, which not only improves the flexibility of the oil discharge operation, can adapt to the oil discharge maintenance operation of the intermediate bearing in different narrow spaces, but also ensures the overall stability and safety reliability of the oil discharge device under different working conditions.

[0050] Example 2

[0051] like Figures 1 to 3 As shown, this embodiment provides a method for using a quick oil discharge device for an intermediate bearing using embodiment 1, comprising the following steps:

[0052] S1, measure the center distance L1 of the lifting holes 61 on both sides of the intermediate bearing, and synchronously adjust the rotation angle of the rotating plates 32 on both sides of the oil discharge 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 between the two connecting rods 41 is adjusted, the two connecting rods 41 are respectively inserted into the corresponding hoisting holes 61 on both sides of the intermediate bearing, and then the locking nuts 42 are installed at the outer ends of the connecting rods 41 passing through the hoisting holes 61. By tightening the locking nuts 42, the connecting rods 41 and the hoisting holes 61 of the intermediate bearing are locked and fixed, thereby fixing the oil drain 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 collecting pan 1, the height of the oil collecting pan 1 and the position of the oil collecting pan 1 relative to the intermediate bearing are adjusted until the oil collecting pan 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 collecting pan 1, thereby effectively preventing the lubricating oil from flowing out of the oil collecting pan 1 during the oil draining operation;

[0055] S4. Check the discharge valve 21 at the bottom of the oil collecting pan 1 to ensure that the discharge valve 21 is in a closed state; then open the discharge screw plug 62 at the bottom of the intermediate bearing to allow the lubricating oil to flow into the oil collecting pan 1;

[0056] S5. Check and ensure that the upper end of the hose 23 is firmly connected to the outlet of the discharge pipe 22 on the oil collecting pan 1, and connect the lower end of the hose 23 to the designated discharge position or collection container, and open the discharge valve 21 until the lubricating oil in the intermediate bearing is completely discharged through the oil discharge device;

[0057] S6. After the oil is drained, close the drain screw 62 at the bottom of the intermediate bearing, remove the oil drain device, and the entire oil drain process is completed.

[0058] When the amount of lubricating oil to be discharged is large, the following steps are also included between step S3 and step S4: rotating the support rods 5 located on both sides of the oil collecting pan 1, and erecting the support rods 5 on both sides on the nearby hull structure. In this embodiment, the support rods 5 are unfolded and erected on the adjacent intermediate bearing base to provide support for the oil collecting pan 1, thereby ensuring the stability of the oil collecting pan 1 during the oil discharge operation and effectively avoiding the problem of tilting or collapse caused by the excessive weight of the oil collecting pan 1; wherein, the amount of lubricating oil to be discharged can be known based on the specification data of the intermediate bearing.

[0059] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. It is known to those skilled in the art that various changes or equivalent substitutions may be made to these features and embodiments without departing from the spirit and scope of the present invention. In addition, under the teachings of the present invention, these features and embodiments may be modified to adapt to specific circumstances and materials without departing from the spirit and scope of the present invention.
