[0024] like Figure 1 As shown, the gripping mechanism of the present invention includes a fixed frame 1, a support rod 2, a gripper bracket body 3, a top shaft 4, and a bottom support plate 5. The gripper bracket body 3 and the bottom support plate 5 are connected to the fixed frame 1 through the support rod 2. The top shaft 4 is connected and fixed to the bottom support plate 5. The gripper bracket body 3 is sleeved between the bottom support plate 5 and the fixed frame 1, and can move and buffer during gripping to prevent excessive contact force from damaging the pulp.

[0025] like Figure 2 As shown, the gripper support body 3 includes a gripper support 31, a rotating plate 32, a connecting rod 33, a guide rod 34, a guide sleeve 35, and grippers 36. The rotating plate 32 is mounted on the gripper support body 3, and the connecting rod 33 connects the rotating plate 32 and the grippers 36. The guide rod 34 is fixed on the gripper support body 3, and the grippers 36 are fixed on the guide rod 34 through the guide sleeve 35. The rotation of the rotating plate 32 drives the grippers 36 on both sides to move closer or further apart to grasp and release the pulp, ensuring the stability of the gripping during the movement.

[0026] like Figure 4 As shown, the gripper 36 includes a structure 361, a gripping tip 362, and a roller 363. The gripping tip 362 is fixed to the structure 361 by a pin and can automatically float according to the height of the pulp during gripping to ensure that it is always in contact with the pulp. The roller 363 is connected to the structure 361 by a pin to prevent the structure 361 from damaging the pulp. When the pulp attachment is working, the entire gripping mechanism rests on the pulp. The rotating plate 32 drives the connecting rod 33 to rotate under the drive of the power source. The connecting rod 33 is connected to the rotating plate 32 and the gripper 36 by a pin. Under the drive of the connecting rod 33, the left and right grippers 36 will move inward. Under the action of the guide rod 34, the gripper 36 can only move inward in the horizontal direction. Therefore, the height of the gripper remains unchanged throughout the entire movement.

[0027] like Figure 3As shown in the diagram of the pulp gripping mechanism, rollers 363 are installed on the grippers 36. The contact surface of the rollers 363 is lower than that of the bottom support plate, and the gap between the two grippers 36 is large. During hoisting operations, the rollers 363 contact the pulp first, ensuring that the grippers 36 can grip the wire rope. In addition, the support rod 2 adopts a stepped shaft form, and the gripper bracket body 3 can float up and down. Therefore, during the gripping process, it can ensure that the bottom support plate is in contact with the pulp, making the entire mechanism grip more stable. At the same time, under the action of gravity, the gripper bracket body 3 keeps the rollers 363 in contact with the pulp, which ensures both smooth rotation and complete gripping of the wire rope.

[0028] like Figure 5 As shown, a top shaft 4 is installed on the bottom support plate 5. The top shaft 4 is fixed to the bottom support plate 5 by a return spring 42. The bottom of the top rod 43 is at the lowest position of the entire mechanism, and a limit plate 41 is installed on top of it. Figure 6 As shown, when the gripping mechanism is not working, the limiting plate 41 of the top shaft 4 contacts the rotating plate 32. The rotating plate 32 has a locking block 321, and the limiting plate 41 contacts the locking block 321. At this time, the rotating plate 32 cannot rotate, and the movement of the entire gripping mechanism is restricted; Figures 7~9 As shown, when the gripping mechanism is completely placed on the pulp, the top shaft 4 is lifted upwards. At this time, the limiting plate 41 separates from the rotating plate 32, and the rotating plate 32 can drive the entire mechanism to work normally. During the transfer of pulp, it can prevent accidental operation and falling, and at the same time, it can help the operator ensure that the pulp has been completely placed.
