[0043] Embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0044] The following describes the submarine cable armor wire anchoring device according to an embodiment of the present invention with reference to the accompanying drawings. Figures 1 to 7 As shown, the submarine cable armored steel wire anchoring device according to an embodiment of the present invention includes a fixing portion, a first anchoring assembly 6 and a second anchoring assembly 7. The fixing portion, the first anchoring frame 61 and the second anchoring frame 71 are sequentially arranged at intervals in the first direction. For example, the fixing portion, the first anchoring frame 61 and the second anchoring frame 71 are sequentially arranged at intervals from front to back.

[0045] like Figures 1 to 5 As shown, the first anchoring assembly 6 includes a first anchoring frame 61 and a plurality of first anchoring parts 62. The first anchoring frame 61 is connected to the fixing part. Specifically, the fixing part includes a fixing plate 1 and a hook 3, the hook 3 is fixed to the first side of the fixing plate 1 through a fixing block 2, and the second side of the fixing plate 1 is connected to the first anchoring frame 61 through a connecting column 4. Thus, the first anchoring assembly 6 can be connected to the fixing part, and the hook 3 is convenient for hanging the submarine cable armored steel wire anchoring device on the cable laying device.

[0046] A plurality of first anchoring portions 62 are fixed on the first anchoring frame 61, and each first anchoring portion 62 is used to fix a steel wire 5. Specifically, a plurality of first anchoring portions 62 are arranged on the first anchoring frame 61 at intervals (evenly) along the circumferential direction.

[0047] like Figure 4 As shown, in some embodiments, the first anchoring portion 62 includes an anchoring tube 622 and a locking ring 624 .

[0048] The anchor tube 622 extends in the first direction, and at least one end of the anchor tube 622 in the first direction is provided with a claw portion 625. The claw portion 625 includes a plurality of claws arranged at intervals in the circumferential direction, and the claws are arranged inwardly and tilted in the first direction away from the anchor tube 622. The steel wire 5 can be passed through the anchor tube 622 and the claw portion 625, and the claws of the claw portion 625 can be elastically deformed. The plurality of claws of the claw portion 625 are arranged at intervals in the circumferential direction, so that when the plurality of claws are elastically deformed (tilted) toward the axial center position of the anchor tube 622, the steel wire 5 can be clamped.

[0049] The locking ring 624 is sleeved on the outer side of the claw part 625, and the locking ring 624 moves in the first direction in the direction adjacent to the anchor tube 622, so that the locking ring 624 can abut against the outer sides of the multiple claws of the claw part 625 and move the claws toward the axial position of the anchor tube 622, so that the multiple claws of the claw part 625 contract and clamp the steel wire 5. For example, the anchor tube 622 extends in the front-to-back direction, and the first anchor frame 61 has a plurality of circular holes 621 extending in the front-to-back direction, and the anchor tube 622 is arranged in the circular holes 621. The inner and outer surfaces of the claws of the claw part 625 are both part of a conical surface, and the multiple claws of the claw part 625 when abutting against each other (substantially) form a conical tube structure, so as to clamp the steel wire 5. The locking ring 624 moves in the direction adjacent to the anchor tube 622 in the front-to-back direction so that the multiple claws of the claw part 625 clamp the steel wire 5.

[0050] like Figures 1 to 4 As shown, in some embodiments, both ends of the anchor tube 622 are provided with claws 625, and the claws 625 at both ends of each anchor tube 622 are located on both sides of the first anchor frame 61 in the first direction, and the claws 625 at both ends of each anchor tube 622 have locking rings 624 matched therewith. Thus, the claws 625 at both ends of the anchor tube 622 can be used to clamp the steel wire 5, thereby further facilitating the anchoring of the steel wire 5.

[0051] In some embodiments, the first anchoring portion 62 includes a first drive screw 623 and a first telescopic rod 626. The axial directions of the first drive screw 623 and the first telescopic rod 626 are both in the first direction. The first drive screw 623 is threadedly connected to the locking ring 624 (the connecting block on it). The telescopic portion of the first telescopic rod 626 is connected to the locking ring 624 (the connecting block on it). The fixed portion of the first telescopic rod 626 is arranged on the first anchoring frame 61. When the first drive screw 623 rotates, it can drive the locking ring 624 to move in the first direction. Specifically, the first telescopic rod 626 is used for limiting, and the first drive screw 623 is rotatably arranged on the first anchoring frame 61. The two ends of the first drive screw 623 are located on both sides of the first anchoring frame 61 in the first direction, and the two ends of the first drive screw 623 are respectively threadedly connected to a locking ring 624. When the first driving screw 623 rotates, it can drive the two locking rings 624 connected to it to move in directions adjacent to each other in the first direction. When the first driving screw 623 rotates in the opposite direction, it can drive the two locking rings 624 connected to it to move in directions away from each other in the first direction. Therefore, the first driving screw 623 can simultaneously make the claw parts 625 at both ends of the anchor tube 622 clamp or loosen the steel wire 5.

[0052] like Figure 3 and Figure 4 As shown, the first anchor assembly 5 includes a first driving part 63, and the first driving part 63 can drive the locking ring 624 to move in the first direction. Specifically, the first driving part 63 includes a gear ring 632 and a plurality of gears 633, and the plurality of gears 633 are arranged on the plurality of first driving screws 623 in a one-to-one correspondence, and the gear ring 632 is meshed with the plurality of gears 633. As a result, when the gear ring 632 rotates, the plurality of gears 633 can be driven to rotate, thereby driving the plurality of first driving screws 623 to rotate, and then the claw parts 625 at both ends of the anchor pipe 622 can clamp or loosen the steel wire 5. For example, the clockwise rotation of the gear ring 632 can drive the claw part 625 to clamp the steel wire 5, and the counterclockwise rotation of the gear ring 632 can drive the claw part 625 to loosen the steel wire 5.

[0053] like Figure 3 As shown, in some embodiments, the first anchoring frame 61 is a circular disk, and the outer peripheral surface of the first anchoring frame 61 has an annular groove 631 with an opening facing outward, and the annular groove 631 is annular and has an opening facing outward. A plurality of gears 633 are located in the annular groove 631, and a gear ring 632 is slidably connected to the outer peripheral surface of the first anchoring frame 61 and covers the annular groove 631. Therefore, when the gear ring 632 rotates relative to the first anchoring frame 61, the gear 633 can be driven to rotate in the annular groove 631. For example, a rotating rod is provided on the outer peripheral surface of the gear ring 632, so that the rotating rod can be manually operated to drive the gear ring 632 to rotate.

[0054] like Figure 5As shown, the first anchoring frame 61 has a plurality of locking holes 638, and the plurality of locking holes 638 are arranged at intervals in the circumferential direction, and a preset distance exists between two adjacent locking holes 638. A fixing groove 634 is provided on one side of the gear ring 632 in the first direction (the side facing the locking holes 638). A slide bar 635 and a clamping block 636 are provided in the fixing groove 634, and the clamping block 636 is slidably provided on the slide bar 635 along the first direction, and a first spring 637 is sleeved on the slide bar 635. The two ends of the first spring 637 are respectively in contact with the bottom wall surface of the fixing groove 634 and the clamping block 636, and the clamping block 636 can be clamped in the clamping hole 638, and the clamping block 636 can be pressed so that the clamping block 636 is separated from the clamping hole 638.

[0055] Specifically, a clamping hole 638 is provided on one side surface of the first anchoring frame 61 in the first direction, the toothed ring 632 is located between two side surfaces of the first anchoring frame 61 in the first direction, and the opening of the fixing groove 634 faces the clamping hole 638. The clamping hole 638 is a circular through hole, and the outer peripheral surface of the clamping hole 638 is a conical surface. The clamping block 636 can be pressed so that the clamping block 636 is disengaged from the clamping hole 638, so that the clamping block 636 can be slidably connected to the inner side surface of the first anchoring frame 61, so that the toothed ring 632 can rotate relative to the first anchoring frame 61. For example, the first anchoring frame 61 has two clamping holes 638, one clamping hole 638 is the loose position of the steel wire 5, and the other clamping hole 638 is the clamping position of the steel wire 5. After the clamping block 636 is separated from the clamping hole 638 in the loose position, the gear ring 632 can be rotated to move the clamping block 636 to the clamping position. At this moment, the first anchoring part 62 clamps the steel wire 5, and the clamping block 636 is pushed into the clamping hole 638 in the clamping position under the elastic force of the first spring 637, thereby fixing the gear ring 632 and making the clamping state of the steel wire 5 stable.

[0056] like Figure 1 , Figure 2 , Figure 6 and Figure 7As shown, the second anchoring assembly 7 includes a second anchoring frame 71 and a plurality of second anchoring parts 73. The second anchoring frame 71 has a plurality of anchoring holes 722 penetrating the second anchoring frame 71 along the first direction. The plurality of anchoring holes 722 are evenly spaced and arranged on the second anchoring frame 71 along the circumferential direction. The plurality of anchoring holes 722 correspond to the plurality of first anchoring parts 62 one by one in the first direction. After passing through the anchoring holes 722, the steel wire 5 can be fixed by the corresponding first anchoring parts 62. The plurality of second anchoring parts 73 can extend into the plurality of anchoring holes 722 one by one. The second anchoring parts 73 can press the steel wire 5 against the wall surface of the anchoring holes 722. That is, the second anchoring assembly 7 can lock the steel wire 5, and the cooperation between the second anchoring assembly 7 and the first anchoring assembly 6 can facilitate further anchoring of the steel wire 5. Moreover, a plurality of anchor holes 722 are evenly spaced along the circumferential direction on the second anchor frame 71, so that after a plurality of steel wires 5 are respectively inserted into the plurality of anchor holes 722, the plurality of steel wires 5 are separated at equal distances. The equally spaced steel wires 5 can more effectively disperse external pressure or tension, thereby improving the structural stability of the entire submarine cable armor layer, ensuring that each steel wire 5 can be evenly stressed, avoiding local stress concentration caused by uneven stress, which helps to extend the service life of the submarine cable and reduce the maintenance and replacement costs caused by fatigue or damage.

[0057] like Figure 6 As shown, in some embodiments, the second anchoring frame 71 has a second driving groove 721 at the center thereof.

[0058] A plurality of second anchoring parts 73 are arranged on the second anchoring frame 71 at intervals along the circumferential direction. The second anchoring part 73 includes a connecting rod 731, a driving block 732 and a fixing plate 734. The fixing plate 734 is connected to the connecting rod 731. The connecting rod 731 is slidably arranged in the second anchoring frame 71 along the radial direction of the anchoring hole 722. The fixing plate 734 is located in the corresponding anchoring hole 722. The driving block 732 is located in the second driving groove 721. The driving block 732 is connected to one end of the connecting rod 731 away from the fixing plate 734. The driving block 732 has a driving inclined surface. The connecting rod 731 is sleeved with a second spring 733. The two ends of the second spring 733 are respectively in contact with the driving block 732 and the wall surface of the second driving groove 721. Specifically, a plurality of connecting rod holes are provided in the second anchoring frame 71, and the extending direction of the connecting rod holes is perpendicular to the first direction. The two ends of the connecting rod holes are respectively connected to the second driving groove 721 and the corresponding anchoring hole 722, and the connecting rod 731 is slidably provided in the connecting rod hole. The second spring 733 can drive the fixing plate 734 to move in the direction adjacent to the second driving groove 721, so that the fixing plate 734 is attached to the wall surface of the anchoring hole 722, and then the steel wire 5 is conveniently inserted into the anchoring hole 722.

[0059] like Figure 6 and Figure 7As shown, the second anchor assembly 7 includes a second driving part 72, and the second driving part 72 can drive the connecting rod 731 to move in the second anchor frame 71. Specifically, the second driving part 72 includes a second driving shaft 645 and a pressing plate 723. The pressing plate 723 is arranged on the second driving shaft 645, and the pressing plate 723 is located in the second driving groove 721. The pressing plate 723 has an annular pressing slope, and the pressing slope and the driving slope are arranged opposite to each other in the first direction. The pressing slope is inclined in the first direction from the direction away from the fixing part to the direction adjacent to the second driving shaft 645, and the driving slope is inclined in the first direction from the direction away from the fixing part to the direction adjacent to the second driving shaft 645. Therefore, when the pressing plate 723 moves in the first direction toward the direction adjacent to the driving block 732, the pressing slope can slide and rub with the driving slope and make the driving block 732 move in the direction away from the second driving shaft 645.

[0060] The axial direction of the second drive shaft 645 is the first direction, and the plurality of second anchoring portions 73 are located on the circumference of the second drive shaft 645. The outer surface of the second drive shaft 645 has threads, and the second drive shaft 645 is inserted through the second anchoring frame 71 and is threadedly connected with the second anchoring frame 71. Thus, the second drive shaft 645 can move in the first direction when rotating, so as to drive the extrusion disk 723 on the second drive shaft 645 to move in the first direction. The second drive shaft 645 can drive the extrusion disk 723 to move in the first direction so that the extrusion disk 723 has a loose position and an extrusion position. In the process of the extrusion disk 723 moving from the loose position to the extrusion position, the extrusion inclined surface extrudes the driving inclined surface so as to drive the second anchoring portion 73 to move in the direction away from the second drive shaft 645, so that the second anchoring portion 73 (fixing plate 734) can press the steel wire 5 against the wall surface of the anchoring hole 722, and at this moment, the second spring 733 is in a compressed state.

[0061] like Figure 6 As shown, in some embodiments, the outer peripheral contour of the cross section of the anchor hole 722 is rectangular, that is, the anchor hole 722 is a rectangular hole. The fixing plate 734 is a rectangular plate, and the shape and size of the fixing plate 734 are adapted to the shape and size of one wall surface of the anchor hole 722. A rubber block 735 is provided on the side of the fixing plate 734 facing away from the connecting rod 731. Specifically, the opening of the connecting rod hole opened in the second anchor frame 71 is opened on the innermost wall surface of the anchor hole 722, and the extension direction of the connecting rod hole opened in the second anchor frame 71 is perpendicular to the innermost wall surface of the anchor hole 722. The rubber block 735 can facilitate the fixing of the steel wire 5.

[0062] In some embodiments, there is at least one second anchoring component 7. For example, there are multiple second anchoring components 7, and the multiple second anchoring components 7 are spaced apart in the first direction.

[0063] In some embodiments, the second anchoring frame 71 is connected to at least one of the fixing portion and the first anchoring frame 61. Specifically, the second anchoring assembly 7 includes a connecting portion 64, and the connecting portion 64 includes at least one connecting threaded rod 644 and at least one connecting threaded sleeve 643. The first anchoring frame 61 is provided with a first anchoring screw 641, and the first anchoring screw 641 and the second driving shaft 645 are connected through the connecting threaded rod 644 and the connecting threaded sleeve 643, so that the distance between the first anchoring assembly 6 and the anchoring assembly in the first direction is adjustable, and does not affect the rotation of the second driving shaft 645, and the distance between the first anchoring assembly 6 and the anchoring assembly in the first direction can be adjusted by adjusting the number of the connecting threaded rod 644 and the connecting threaded sleeve 643. For example, the connecting part 64 includes two stud bolt blocks 642, and the two stud bolt blocks 642 are provided with connecting threaded rods 644 at both ends of the first direction. The first anchoring screw 641 is connected to a connecting threaded rod 644 of the first stud bolt block 642 through a connecting threaded sleeve 643, the connecting threaded rod 644 between the two stud bolt blocks 642 is connected through a connecting threaded sleeve 643, and the second driving shaft 645 is connected to a connecting threaded rod 644 of the second stud bolt block 642 through a connecting threaded sleeve 643.

[0064] According to the submarine cable armored steel wire anchoring device of the embodiment of the present invention, one end of a plurality of steel wires 5 is inserted into the anchoring hole 722 of the second anchoring assembly 7, so that the plurality of steel wires 5 are separated and fixed at equal distances, and then the first anchoring assembly 6 is used for secondary fixation, so that the plurality of steel wires 5 can be fixed at equal distances in the fixing plate 1, and the relevant equipment for laying the cable lays the cable by pulling the hook 3. Through the first anchoring assembly 6 and the second anchoring assembly 7, a plurality of steel wires 5 can be anchored and locked uniformly, and there is no need to anchor a single steel wire separately, thereby improving the work efficiency of the user and reducing the difficulty of operation.

[0065] The first anchoring assembly 6 and the second anchoring assembly 7 of the submarine cable armored steel wire anchoring device according to the embodiment of the present invention can separate the steel wires 5 at equal distances.
