The structure is simple and the operation is convenient, so it can be used for long-term work.

[0026] Specifically, the slewing bearing is provided with four slewing bearing sub-bodies 1, and the connecting plate 2 and the limit rod 3 are installed through the connecting groove 101 on the outer side of the slewing bearing sub-bodies 1, which are connected and positioned with each other. By inserting the connecting plate 2 outside the plug plate 103 between two adjacent slewing bearing sub-bodies 1, the slewing bearing sub-bodies 1 are quickly fixed for installation and disassembly. The structure is simple and the operation is convenient, so that long-term work can be carried out.

[0027] In order to solve the problem of poor connection position stability of existing segmented slewing bearings in actual use, which affects long-term operation, please refer to Figure 1 - Figure 4 , this embodiment provides the following technical solutions:

[0028] The insert plate 103 is welded to the slewing bearing split 1, and an integrally formed positioning slot 104 is provided on the outer side of the insert plate 103. During the installation work, the limiting rod 3 is kept in a stable position by pushing the two limiting blocks 302 into the interior of the positioning slot 104.

[0029] Limiting blocks 302 are installed at both ends of the limiting rod 3 . The limiting blocks 302 are connected to the limiting rod 3 via fixing screws. The limiting blocks 302 are embedded in the positioning slots 104 and engaged with the inserting plate 103 .

[0030] One end of the limiting rod 3 extends to the connecting sleeve 301 and is threadedly connected to the connecting sleeve 301, and the other end of the limiting rod 3 is rotatably connected to the limiting block 302 through a bearing. An adjusting nut 303 is installed in the middle of the connecting sleeve 301. By adjusting the adjusting nut 303, the adjusting nut 303 drives the connecting sleeve 301 to rotate, and the connecting sleeve 301 adjusts the position of the limiting rod 3 and the spring damper inside the connecting sleeve 301, so that the limiting rod 3 tightly squeezes the inserting plate 103.

[0031] A spring damper is provided inside the limiting rod 3, and the two ends of the spring damper are fixedly connected to the connecting sleeve 301 and the limiting rod 3 respectively. The spring damper can buffer the vibration generated by the slewing bearing during operation, thereby keeping the position between the inserting plate 103 and the connecting plate 2 stable.

[0032] Specifically, during the installation work, the limit rod 3 is installed by pushing the two limit blocks 302 into the interior of the positioning slot 104, and by adjusting the adjusting nut 303, the adjusting nut 303 drives the connecting sleeve 301 to rotate, and the connecting sleeve 301 adjusts the position of the limit rod 3 and the spring damper inside the connecting sleeve 301, so that the limit rod 3 tightly squeezes the plug plate 103, maintaining the position stability between the plug plate 103 and the connecting plate 2, which is conducive to long-term work and further improves the work quality.

[0033] Working principle: When in use, by setting four slewing support splits 1, the cutouts 102 will fit the four slewing support splits 1 tightly for installation and disassembly. The connecting plate 2 and the limit rod 3 are installed through the connecting groove 101 on the outside of the slewing support split 1, connected and positioned with each other. By inserting the connecting plate 2 outside the plug plate 103 between two adjacent slewing support splits 1, the slewing support split 1 is quickly fixed for installation and disassembly. The structure is simple and the operation is convenient, so it can be used for long-term work. During the installation work, the limit rod 3 is installed by inserting the two limit blocks 3 02 is pushed into the interior of the positioning slot 104, and the adjusting nut 303 is adjusted. The adjusting nut 303 drives the connecting sleeve 301 to rotate, and the connecting sleeve 301 adjusts the position of the limit rod 3 and the spring damper inside the connecting sleeve 301, so that the limit rod 3 tightly squeezes the plug plate 103, maintaining the position stability between the plug plate 103 and the connecting plate 2, and the spring damper is used to buffer the vibration generated by the slewing bearing during work, thereby maintaining the position stability between the plug plate 103 and the connecting plate 2, which is conducive to long-term work and further improves the work quality.
