[0028] In a specific application scenario, the axis positioning module 8 is mainly suitable for the axis positioning link in the axis positioning process, that is, the axis positioning module 8 uses the displacement sensor 831 and the slide bar 830 to record the trajectory of the support bracket 823 that is in contact with the inner wall of the knife ring body 4 along the rotation trajectory with the axis rod 7 as the axis, thereby calculating the offset between the axis of the axis rod 7 and the axis of the knife ring body 4 according to the trajectory, so that the device can quickly and accurately measure the axis offset between the axis rod 7 and the knife ring body 4, thereby greatly reducing the workload of the operator, improving the efficiency of the axis positioning of the knife ring body 4, and thus improving the overall efficiency of disassembling the knife ring body 4.

[0030] Specifically, after the axis positioning of the knife ring body 4 is completed, the hydraulic rod 4 907 is started, and the output end of the hydraulic rod 4 907 is extended to push the disc 904 to drive the connecting plate 906 to move on the rectangular opening 905 to the side of the rectangular opening 905 away from the knife ring body 4, so that the connecting plate 906 pushes the mounting ring 901 to move to the outermost side of the knife ring body 4, and the hydraulic rod 5 910 is started. The hydraulic rod 5 910 pushes the extrusion ring 908 to approach the rotating seat 902, so that the extrusion ring 908 lifts the rotating seat 902, and the rotating seat 902 drives the hollow rod 4 917 to rotate in the direction of the knife ring body 4. After the extrusion ring 908 is completely fitted with the mounting ring 901, the rotating The seat 902 will maintain a vertical posture with the axial rod 7 on the mounting ring 901, and the hydraulic rod four 907 will be started. The output end of the hydraulic rod four 907 will be retracted, so that the hydraulic rod five 910 can continue to push the extrusion ring 908 and the mounting ring 901 to move toward the position of the knife ring body 4. After the rotating seat 902 and the edge of the knife ring body 4 are located on the same plane, the motor three 914 is started. The motor three 914 drives the screw rod 915 to rotate, so that the screw rod 915 pushes the hollow rod four 917 connected to the sleeve 916 to extend from the hollow rod three 913, so that the rubber pad 912 on the contact frame 911 fits with the edge of the knife ring body 4, thereby completing the three-point support of the knife ring body 4.

[0031] In specific application scenarios, the supporting and stabilizing module 9 is mainly suitable for the supporting and stabilizing link in the supporting and stabilizing process, that is, the supporting and stabilizing module 9 uses the mounting ring 901 and the extrusion ring 908 to keep the rotating seat 902 in a folded state when the axial rod 7 enters the knife ring body 4, thereby avoiding the contact frame 911 from hooking the blade 5 on the knife ring body 4, ensuring the stability of the device and the knife ring body 4, and using the rotating rotating seat 902 to drive the retractable hollow rod four 917, so that the contact frame 911 can stably support the knife ring bodies 4 of different sizes, so that the knife ring body 4 can remain in a relatively stable state when being removed from the body 1, avoiding damage and deformation of the knife ring body 4 and the blade 5 thereon.

[0032] Working principle: After the knife ring body 4 in the machine body 1 is pushed out of the machine body 1 by the propulsion rod 3 on the machine body 1, the universal wheel 10 is used to move the installation frame 6 to a position roughly aligned with the knife ring body 4, and the installation frame 6 is supported by the hydraulic rod 6 11 and the load-bearing plate 12, and the hydraulic rod 807 is started.

Under the elastic force of the spring 826, the hollow rod 828 extends from the hollow rod 1 825, so that the roller 824 on the support bracket 823 can be aligned with the inner of the knife ring body 4. The outer gear ring 815 meshing with the gear 2 816 rotates, so that the outer gear ring 815 drives the push ring 814 to rotate. During the rotation of the push ring 814, since the shaft rod 7 is not at the rotation axis of the knife ring body 4, the support bracket 823 that is in contact with the inner wall of the knife ring body 4 moves telescopically on the hollow rod 1 825 during the movement of the shaft rod 7.

After coincidence, start the hydraulic rod 3 822, and the output end of the hydraulic rod 3 822 pulls the embedded ring 820 into the embedded groove 818, so that the embedded ring 820 is engaged with the rectangular block 819, so that the push ring 814 no longer rotates, and tightens the fixing bolt 829 to prevent the hollow rod 2 828 from sliding. After the axis positioning of the knife ring body 4 is completed, Start the hydraulic rod 4 907, the output end of the hydraulic rod 4 907 extends to push the disc 904 to drive the connecting plate 906 to move on the rectangular opening 905 to the side of the rectangular opening 905 away from the knife ring body 4, so that the connecting plate 906 pushes the mounting ring 901 to move to the outermost side of the knife ring body 4, start the hydraulic rod 5 910, the hydraulic rod 5 910 pushes the extrusion ring 908 to approach the rotating seat 902, so that the extrusion ring 908 tilts the rotating seat 902, so that the rotating seat 902 drives the hollow rod 4 917 to rotate in the direction of the knife ring body 4, after the extrusion ring 908 is completely fitted with the mounting ring 901, the rotating seat 902 will maintain a vertical posture with the axial rod 7 on the mounting ring 901, start the hydraulic rod 4 907,The output end of hydraulic rod 4 907 is retracted, so that hydraulic rod 5 910 can continue to push extrusion ring 908 and mounting ring 901 to move to the position of knife ring body 4. After the rotating seat 902 and the edge of knife ring body 4 are located on the same plane, motor 3 914 is started, and motor 3 914 drives screw 915 to rotate, so that screw 915 pushes hollow rod 4 917 connected to sleeve 916 to extend from hollow rod 3 913, so that rubber pad 912 on contact frame 911 fits with the edge of knife ring body 4, so as to complete three-point support for knife ring body 4, and hydraulic rod 1 804 is started, and hydraulic rod 1 804 lifts axial rod 7, so that knife ring body 4 is separated from propulsion rod 3, so that knife ring body 4 is disassembled from machine body 1.
