[0049] Reference Figure 2The turntable 11 is an annular structure. The turntable 11 is horizontally arranged and rotatably connected to the operating table. The turntable 11 is driven to rotate on the operating table by installing a driving motor under the operating table. A central tube 5 is installed at the center of the turntable 11. The upper top of the central tube 5 is provided with a V-shaped opening for placing the rope.

[0050] The rotating wire clamp assembly 12 includes a mounting frame 121, a fixed block 122, a blocking block 123, a clamping block 124, a spring 125 and a push cylinder 14.

The fixed end 6 of the wire rope is located above the turntable 11. Figure 2 and Figure 5First, the driving motor drives the turntable 11 to rotate, and the rotating clamping assembly 12 is rotated to the top of the suction assembly 13. The blocking block 123 is pushed by the pushing cylinder 14. After the forward pushing force of the pushing cylinder 14 overcomes the elastic force of the spring 125, the connecting rod is pushed toward the direction close to the center tube 5, thereby driving the clamping block 124 and the fixing block 122 to separate. At this time, the lifting cylinder pushes upward to push the suction pipe 131 out from between the clamping block 124 and the fixing block 122. At the same time, the suction fan is turned on. When the free end of the wire rope is above the suction pipe 131, the suction force generated by the suction fan sucks the free end of the wire rope into the suction pipe through the suction pipe 131. 131, and then move the fixed end 6 of the rope to the attachment of the central tube 5, and the fixed end 6 is located above the turntable 11. At this time, the lifting cylinder is controlled to descend, and the suction pipe 131 descends to below the fixed block 122 and the clamping block 124, so that the rope is pulled through between the fixed block 122 and the clamping block 124 under the action of the suction force of the suction pipe 131. At this time, the pushing cylinder 14 is withdrawn, and under the action of the spring 125, the clamping block 124 and the fixed block 122 clamp one end of the rope, and then the turntable 11 can be controlled to drive the rope to rotate clockwise around the tube below the fixed end 6 for one circle and 90°, that is, the turntable 11 stops after rotating 450° to form a rope loop.

[0055] Reference Figure 4The automatic knotting device also includes a wire-pulling mechanism 4, which includes a guide rod 41, a movable seat 42, an adjusting cylinder 43 and a lever 44. The guide rod 41 is installed on the operating table and is located on the side of the threading mechanism 2 away from the suction assembly, and the installation direction of the guide rod 41 is perpendicular to the pushing direction of the extension cylinder 211. The movable seat 42 is fixed by bolts and slides on the guide rod 41. The adjusting cylinder 43 is installed on the movable seat 42 by bolts, and its pushing end faces the end away from the guide rod 41 and is perpendicular to the guide rod 41. The lever 44 is welded to the pushing end of the adjusting cylinder 43, and the length direction of the lever 44 is parallel to the length direction of the guide rod 41.

[0056] Reference Figure 2-Figure 5 When the wire rope is in front of the flip motor 221, the translation assembly drives the extension cylinder 211 and the flip motor 221 to move, so that the wire clamp 212 is located above the rotating wire clamp assembly 12, and the rotating wire clamp assembly 12, the center tube 5 and the wire clamp 212 are aligned in the radial direction of the turntable 11, and the wire rope is in the opening position of the front end of the clamp rod 2122 of the wire clamp 212, and the extension cylinder 211 pushes the wire clamp 212 toward the side of the center tube 5. As the wire clamp 212 moves, the wire rope enters between the two clamp rods 2122 of the wire clamp 212, and the front end of the wire clamp 212 is close to the center tube 5; at this time, the turntable 1 is controlled. 1 is rotated 45° counterclockwise, and the blocking block 123 is pushed by another pushing cylinder 14 to release the wire rope, and then the translation assembly drives the extension cylinder 211 and the flip motor 221 to move to the side away from the wire suction position along the extension direction perpendicular to the extension cylinder 211, so that the wire clamp 212 avoids the central tube 5, and the extension cylinder 211 continues to drive the wire to extend forward, so that the wire clamp 212 is located on the side of the central tube 5 away from the wire suction position. At this time, the moving seat 42 is controlled to move along the guide tube toward the direction close to the rotating motor, and at the same time, the lever 44 is driven by the adjusting cylinder 43 to move the wire rope until the wire rope is aligned with the V-shaped opening on the top of the central tube 5.

[0057] The initial position of the wire clamp 212 is outside the range of the wire rope driven by the rotating wire clamp assembly 12, and the wire clamp 212 does not affect the winding of the wire rope.

[0058] Reference Figure 2 The line hooking mechanism 3 includes a dragging hook 31 and a telescopic tube 32. The telescopic tube 32 is located at the center of the turntable 11 and is sleeved on the outside of the central tube 5 and is slidably connected to the central tube 5. The dragging hook 31 is installed at the center of the central tube 5. The central tube 5, the telescopic tube 32 and the dragging hook 31 are all individually connected to the bottom with a control cylinder. An extrusion block that is embedded with the dragging hook 31 is welded on the inner wall of the central tube 5.

[0059] Reference Figure 2 , Figure 3 , Figure 4 and Figure 6, the lever 44 moves the wire rope to the front of the opening of the drag hook 31 and aligns it with the V-shaped opening. The flip motor 221 drives the wire clamp 212 to rise from one side of the center tube 5 and pass directly above the center tube 5. The wire rope clamped by the wire clamp 212 moves to the top of the rope loop and then flips to the other side of the center tube 5 and then descends, so that the wire rope bypasses the V-shaped opening of the center tube 5 and is placed on the V-shaped opening. Then the wire clamp 212 is controlled to release the wire rope and retreat. At the same time, the lever 44 also retreats under the action of the adjusting cylinder 43. Then the drag hook 31 pulls the wire rope down to the extrusion block, and the wire rope is fixed by the drag hook 31 and the extrusion block to pass through the rope loop formed by the wire rope. Then the center line tube is controlled to sink, and the telescopic tube 32 is controlled to push upward, thereby completing the entire knotting process of the wire rope. Among them, the towing hook 31 is on the side of the central tube 5 close to the flip motor 221, the opening side of the towing hook 31 covers the lowest position of the V-shaped opening, and the top end of the towing hook 31 is conically set, that is, the towing hook 31 and the top end of the central tube 5 away from the flip motor 221 have sufficient space to allow the rope to pass through the towing hook 31 easily, ensuring that the towing hook can fall into the V-shaped opening.
