[0037] The stabilizing support unit 300 includes a support plate 301 arranged on the movable clamping assembly 201, which is used to support the adjustment activity of the movable clamping assembly 201, a rotating support assembly 302 arranged on the support plate 301, which is used to drive the support plate 301 to rotate, thereby driving the marine propeller 100 on the movable clamping assembly 201 to rotate, so as to facilitate the processing and maintenance of the marine propeller 100, and a support frame 303 arranged on the rotating support assembly 302, which plays a supporting role and is used to enhance the stability of the device.

[0038] In summary, when the lifting tool brings the marine propeller 100 close to the movable clamping assembly 201, the support assembly 202 is controlled to shrink the movable clamping assembly 201 to a state much smaller than the current hub diameter of the marine propeller 100, so that the movable clamping assembly 201 can be quickly passed through the hub of the marine propeller 100. When the marine propeller 100 is hung on the movable clamping assembly 201 to the tail end, the movable clamping assembly 201 is driven to open by pushing the support assembly 202 until the outer wall of the movable clamping assembly 201 is tightly fitted with the inner wall of the hub of the marine propeller 100. At this time, the movable clamping assembly 201 completes the support and clamping of the marine propeller 100. The position of the marine propeller 100 on the movable clamping assembly 201 is relatively fixed. At this time, the centers of the marine propeller 100 and the movable clamping assembly 201 coincide. At this time, the clamping stabilizing assembly 203 is clamped onto the movable clamping assembly 201 and is in close contact with the marine propeller 100, thereby further enhancing the stability of the marine propeller 100 on the movable clamping assembly 201, preventing the marine propeller 100 from sliding on the movable clamping assembly 201, and improving the safety of clamping the marine propeller 100. At this time, the marine propeller 100 is driven to rotate by the support plate 301 in cooperation with the rotating support assembly 302, so that the marine propeller 100 can be quickly processed and repaired, thereby improving the maintenance efficiency.

The button 203b-6 and the closing ring 203b-1 are used to close the tightening strip 203b-2 to prevent the popping out of the tightening strip 203b-2 from affecting the processing and maintenance of the marine propeller 100. The connecting seat 203b-3 is used to support the gear shaft 203b-4. The gear shaft 203b-4 rotates and cooperates with the tooth groove 203b-5 to drive the tightening strip 203b-2 to firmly fasten all the fixing blocks 203a-1 on the supporting claw 201a. The knob 203b-6 is used to drive the gear shaft 203b-4 to rotate.

[0049] The fixing block 203a-1 is provided with a tightening groove b which matches the tightening strip 203b-2 and is used to limit the position of the tightening strip 203b-2, so as to facilitate adjustment of the tension of the tightening strip 203b-2.

[0050] The abutment member 203c includes a fixing strip 203c-1 disposed on the fixing block 203a-1, a friction strip 203c-2 disposed on the fixing strip 203c-1 close to the marine propeller 100, a guide column 203c-3 disposed on the friction strip 203c-2 and slidably connected to the fixing strip 203c-1, a threaded column 203c-4 disposed on the friction strip 203c-2 and slidably connected to the fixing strip 203c-1, and an adjusting nut 203c-4 disposed on the threaded column 203c-4 by a thread. -5, the fixing strip 203c-1 is used to cooperate with the guide column 203c-3 to limit the movement of the friction strip 203c-2, the guide column 203c-3 is used to abut against the hub of the marine propeller 100 to increase the stability of the marine propeller 100, the threaded column 203c-4 and the adjusting nut 203c-5 cooperate to drive the friction strip 203c-2 to move through the guide column 203c-3, fill the gap between the marine propeller 100 and the fixing block 203a-1, and improve the stability of the marine propeller 100 on the supporting claw 201a;

[0052] The rest of the structure is the same as that of Example 1.

[0053] In summary, when the lifting equipment moves the marine propeller 100 close to the supporting claw 201a, the electric cylinder 202a is started to drive the movable supporting shaft 202b to move backward, and the supporting claw 201a is gathered by the movable supporting rod 201c-4. At this time, the outer diameter of the supporting claw 201a is much smaller than the inner diameter of the hub of the marine propeller 100. At this time, the supporting claw 201a can easily pass through the hub of the marine propeller 100. At this time, the marine propeller 100 is moved to the innermost part of the supporting claw 201a and the supporting plate 301 by the lifting equipment.

At this time, the annular tensioning spring 203a-5 is stretched, pulling the fixing block 203a-1 tightly onto the supporting claw 201a. At this time, the card block 203a-2 passes through the approaching arc surface a, and when passing through the card slot 201a-1, it is squeezed and drives the card block 203a-2 to leave the current card slot 201a-1 until it moves to the card slot 201a-1 closest to the marine propeller 100. At this time, the annular tensioning spring 203 Under the action of a-5, the clamping block 203a-2 is firmly clamped with the clamping slot 201a-1. At this time, the knob 203b-6 is turned to drive the tightening strip 203b-2 to be tightened in the tightening slot b through the gear shaft 203b-4, and the fixed block 203a-1 is firmly fixed on the supporting claw 201a.

[0061] The rest of the structure is the same as that of Example 2.

[0062] In summary, after the marine propeller 100 is fixed to the supporting claw 201a, the marine propeller 100 can be processed and repaired. When the maintenance personnel have finished repairing the current area and need to repair the next area, the servo motor 302a-1 is started.
