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. Example

[0012] like Figure 1 , Figure 2 and Figure 3As shown in one embodiment of this utility model, an online replacement device for a marine loading and unloading boom slewing bearing includes a support member 1 and a lifting member 2. A fixing clamp 102 is rotatably connected to the mounting seat 101 of the support member 1, facilitating the stable installation of the entire device on the support column of the loading and unloading boom. This allows for effective lifting of the boom during the replacement of the slewing bearing components, enabling smooth disassembly and replacement and improving work efficiency. A lead screw 103 is fixedly connected to a support plate 104 on the other side of the mounting seat 101, and a worm gear 207 of the lifting member 2 is threadedly connected to the lead screw 103. The worm gear 207 is rotatably mounted on the housing 201. The internal cavity is connected to the worm gear 206, which is also connected to the drive motor 202. This allows the drive motor 202 to operate when the boom needs to be lifted during use. The worm gear 206 drives the worm wheel 207 to rotate on the lead screw 103, thereby driving the entire lifting component 2 to move on the lead screw 103 and complete the lifting of the boom. This allows the slewing bearing component to be easily disassembled and replaced, improving the convenience of operation. Furthermore, a lifting rod 204 is fixedly connected to the support rod 203 on the housing 201, and a hook 205 is installed on the lifting rod 204, facilitating smooth lifting operations of the boom.

[0013] like Figure 1 and Figure 3 As shown, in some embodiments, the connecting seat 2031 integrally provided at the lower end of the support rod 203 is fixedly connected to the housing 201, which facilitates the stable installation of the support rod 203 on the housing 201, so that it can move together with the housing 201 on the lead screw 103 during use. A sliding sleeve 2032 is fixedly connected to the support rod 203 through a connecting rod. The sliding sleeve 2032 is slidably connected to the lead screw 103, which improves the stability of the support rod 203 moving on the lead screw 103 and ensures stable use. In addition, the housing 201 is provided with a through hole for inserting the lead screw 103, which ensures that the housing 201 is stably installed on the lead screw 103 and ensures smooth movement on the lead screw 103 during use. One end of the boom 204 is fixedly connected to a fixing sleeve 2041, which is fixedly connected to the body of the support rod 203. This facilitates the stable installation of the boom 204 on the support rod 203, allowing the support rod 203 to move along with the boom 204 during vertical movement. The other end of the boom 204 is equipped with an anti-detachment baffle 2042, which effectively prevents the hook 205 from sliding off the boom 204. The hook 205 is fixedly connected to a connecting sleeve 2051, which is fitted onto the body of the boom 204. This facilitates the stable installation of the hook 205 on the boom 204, enabling effective lifting of the boom. After the connecting bolts of the slewing bearing are removed, the boom can be separated from the support column, thus smoothly completing the disassembly and replacement of the slewing bearing and improving operational convenience. The worm gear 207 is rotatably mounted in the internal cavity of the housing 201 via a bearing seat. The bearing seat is fixedly connected to the inner wall of the housing 201, facilitating the smooth rotation of the worm gear 207 within the housing 201. This allows the housing 201 and its components to move smoothly on the lead screw 103.

One end of the drive shaft is connected to the output shaft of the drive motor 202. The drive motor 202 is fixedly connected to the outer wall of the housing 201. This allows the drive motor 202 to operate when the boom needs to be detached from the support column during use. The drive motor 202 drives the worm gear 207 to rotate on the lead screw 103 via the worm gear 206, thereby moving the worm gear 207 on the lead screw 103. This enables the entire lifting component 2 to move on the lead screw 103, ensuring smooth lifting operations of the boom.

[0014] like Figure 1 and Figure 2 As shown, in some embodiments, a reinforcing rib 105 is fixedly connected between the mounting base 101 and the support plate 104 to enhance the strength of the connection between the two and ensure stable use. A stop 107 is installed at the top of the lead screw 103 on the support plate 104 to form a stable and effective limiting stop, preventing the lifting component 2 from sliding off the lead screw 103 during the upward movement, thus ensuring stable use. Furthermore, one end of the fixing clamp 102 is rotatably connected to the mounting base 101 via a rotating shaft, and the other end is integrally bent to form a connecting... The connecting part has a mounting hole on which a fastening bolt 106 is inserted, and an anti-slip block is placed on the inner side of the fixing clamp 102 to facilitate smooth rotation on the mounting base 101 during use. After unfolding, it can be smoothly installed on the support column of the loading and unloading arm together with the mounting base 101. The fastening bolt 106 and the anti-slip block work together to stably install the fixing clamp 102 on the support column of the loading and unloading arm, ensuring stable installation and preventing it from sliding on the support column during use.
