Description
Technical Field
[0001] The utility model relates to the technical field of cleaning of ship zero bearings, in particular to a ship zero bearing hoisting cleaning tool. Background Art
[0002] The ship's main engine needs to be equipped with a No. 0 bearing at the front end of the crankshaft due to torsional vibration calculations. The appearance of the No. 0 bearing reduces the static and dynamic loads of the front bearing, but the No. 0 bearing is large in size. At the same time, when the No. 0 bearing is in use, stains will adhere to the outside of the No. 0 bearing. Therefore, the stains on the outside of the No. 0 bearing need to be cleaned regularly. In order to facilitate the staff to clean the high position of the bearing, a hoisting structure is used to drive the cleaning tools to clean the outside of the bearing.
[0003] In order to facilitate the cleaning of the outside of the bearing, it is necessary to control the rotation of the lifting structure around the outside of the bearing, which leads to high technical requirements for lifting. Lifting deviation will lead to a series of chain problems such as the front-end bearing gear throw-off, wear of the No. 0 bearing bushing, and increased vibration of the main engine under high load. The existing lifting and installation process is to use two slings to bind and lift. After lifting, it is easy to shake and cause the slings to slip, and it is not easy to adjust. There are safety risks in this process, which affects the alignment. To avoid such problems, we have developed a marine No. 0 bearing lifting and cleaning tool. Utility Model Content

The support frame 3 limits the feeding of the rolling shaft 4. The rolling shaft 4 is movably sleeved inside the support frame 3. The rolling shaft 4 limits the positions of the washer 5 and the rolling bearing 6. The washer 5 and the rolling bearing 6 are sequentially sleeved on the outside of the inner side of the rolling shaft 4. The washer 5 reduces the friction when the equipment rotates. The outside of the rolling bearing 6 is sleeved with a support roller 7. The support roller 7 contacts the outside of the No. 0 bearing 1. At the same time, the support plate 2 can rotate around the outside of the No. 0 bearing 1. That is, through the axial circular motion, the cleaning tool can be driven to accurately clean the outside of the No. 0 bearing 1. Lifting lugs 8 are movably sleeved on both sides of the support plate 2. Traction ropes 10 are fixedly connected to both sides of the lower part of the support plate 2. The traction ropes 10 hoist and traction the position of the cleaning structure 11. A cleaning structure 11 is sleeved on the outside of the support plate 2. A cleaning roller 12 is sleeved in the middle of the cleaning structure 11. When the cleaning roller 12 rotates around the outside of the No. 0 bearing 1, the cleaning roller 12 can clean the outside of the No. 0 bearing 1.
[0023] Please refer to Figure 5 , two groups of support frames 3 are installed on the inner side of the support plate 2. A gasket is installed between the connection of the support frame 3 and the rolling shaft 4. By installing a gasket between the support frame 3 and the rolling shaft 4, the gasket protects the rolling shaft 4 during installation.
[0024] Please refer to Figure 5, the washer 5 is clamped between the support frame 3 and the rolling bearing 6. At the same time, the support roller 7 is sleeved outside the washer 5 and the rolling bearing 6. By clamping the washer 5 between the support frame 3 and the rolling bearing 6, the washer 5 plays a role in filling the gap and improving the sealing performance. And the support roller 7 is arranged outside the washer 5 and the rolling bearing 6, reducing the friction when the support roller 7 rotates.
[0025] Please refer to Figure 5 , the outside of the support roller 7 bulges, and the support roller 7 is fitted and installed outside the No. 0 bearing 1. Through the bulging state of the outside of the support roller 7, when controlling the two groups of support rollers 7 to be in contact with the outside of the No. 0 bearing 1, the contact area of the parts is reduced. It ensures that the hoisted cylindrical part can rotate easily, to a certain extent ensuring the safety and reliability of hoisting and facilitating the operation of the hoisting personnel.

Through the towing of the cleaning structure 11 by the towing rope 10, and the cleaning structure 11 drives the cleaning roller 12 to be fitted and installed outside the No. 0 bearing 1. When the cleaning roller 12 rotates around the outside of the No. 0 bearing 1, the cleaning roller 12 can scrape off the impurities on the outside of the No. 0 bearing 1, thereby cleaning the outside of the No. 0 bearing 1.
[0028] Please refer to Figure 3 , a jacket 13 is fixedly connected to the side of the cleaning structure 11. A fastening bolt 14 is installed inside the side of the jacket 13. An auxiliary wheel 15 is arranged inside the jacket 13. Two groups of auxiliary wheels 15 are installed inside the jacket 13. By installing a jacket 13 outside the cleaning structure 11 and controlling the jacket 13 to be sleeved outside the No. 0 bearing 1, tightening the fastening bolt 14, and controlling the auxiliary wheel 15 to contact the outside of the No. 0 bearing 1, the cleaning roller 12 can be driven to closely fit outside the No. 0 bearing 1. At the same time, when controlling the support plate 2 to rotate around the No. 0 bearing 1, the cleaning roller 12 can be driven to rotate synchronously outside the No. 0 bearing 1, that is, the cleaning roller 12 can scrape and clean the impurities outside the No. 0 bearing 1.
[0029] Working principle: When in use, the traction device is used to drive the support plate 2 to be arranged on the side of the No. 0 bearing 1. At the same time, the support roller 7 is controlled to be in contact with the outside of the No. 0 bearing 1. The middle part of the support roller 7 bulges outwards, so that the contact surface between the support roller 7 and the No. 0 bearing 1 can be reduced, avoiding scratches on the outside of the No. 0 bearing 1. Moreover, a cleaning structure 11 is installed outside the lifting lug 8. The cleaning structure 11 drives the cleaning structure 11 to be hoisted outside the No. 0 bearing 1. By tightening the fastening bolt 14, the fastening bolt 14, that is, the cleaning roller 12, is arranged outside the No. 0 bearing 1. When the traction device drives the support plate 2 to rotate, the support plate 2 can drive the cleaning roller 12 to clean the outside of the No. 0 bearing 1.
