[0002] In the production process of submarine cables, a stranding machine is required for steel wire armoring. In order to ensure the synchronous movement and stranding quality of each wire during the stranding process, a longer synchronous tube is often used in the stranding machine, and the rotation of the synchronous tube is driven by the tail tube.

[0003] The tail tube and the synchronous tube are usually connected by flanges or clamps. For example, in the prior art, a patent application with application number 2023100371477 discloses a cable core anti-twist device, a cage twisting machine, a cable core armoring system and method, and the ends of the synchronous tube are connected and fixed by a clamping mold. Since the length of the synchronous tube is several meters, it is difficult to ensure the concentricity of the synchronous tube and the tail tube during the production process, and radial runout or slight swing is prone to occur. Although the radial runout or slight swing during the rotation of the synchronous tube will not damage the structure of the flange or the clamp, it will cause the synchronous tube to break, which greatly shortens the service life of the synchronous tube and needs to be improved.

[0017] The technical solutions in the embodiments of the present invention are described clearly and completely below. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0018] See also Figure 1 to Figure 6 , the embodiment of the present invention includes: like Figure 1 The stranding machine synchronous pipe adaptive connection assembly shown in the figure is used for the transmission connection between the tail pipe 22 and the synchronous pipe 21, and includes: a synchronous pipe connecting sleeve 1, a tail pipe connecting sleeve 2 and a gear ring 3, as shown in FIG. Figure 4 and Figure 5 As shown, the outer end of the synchronous pipe connecting sleeve 1 is provided with a first separation groove 18 extending axially inward, and the end of the first separation groove 18 is provided with a second separation groove 10 extending 160-200° along the outer circumference of the synchronous pipe connecting sleeve 1. Figure 4 The angle of the synchronous tube connection sleeve is 180°, so as to form a first elastic arc clamping plate 11 at the outer end of the synchronous tube connection sleeve to achieve clamping of the synchronous tube 21 after it is inserted into the synchronous tube connection sleeve 1.

[0019] In addition, one end of the first elastic circular arc clamping plate 11 remains connected to the synchronous tube connecting sleeve 1 to prevent the first elastic circular arc clamping plate 11 from being separated from the synchronous tube connecting sleeve 1 .

[0020] A first screw mounting hole 9 pointing vertically to the first separation groove 18 is provided on the first elastic arc clamping plate 11, and a first threaded hole corresponding to the first screw mounting hole 9 is provided on the outer circle of the synchronous pipe connecting sleeve 1. After the synchronous pipe 21 is inserted into the synchronous pipe connecting sleeve 1, a screw is installed in the first screw mounting hole 9, and the screw cooperates with the first threaded hole to lock the first elastic arc clamping plate 11, thereby clamping the synchronous pipe 21. In this embodiment, a first keyway 19 extending axially is provided in the inner concave of the synchronous pipe connecting sleeve 1, which is convenient for installing a key block, and cooperates with the keyway of the outer circle of the synchronous pipe 21 to avoid the torsion problem of the synchronous pipe 21.

[0021] A third separation groove 15 extending axially inward is provided at the outer end of the tail pipe connecting sleeve 2, and a fourth separation groove 13 extending 160-200° along the outer circumference of the tail pipe connecting sleeve 2 is provided at the end of the third separation groove 15. Figure 5 The angle of the second elastic arc clamping plate 12 is 180°, so that the second elastic arc clamping plate 12 is formed at the outer end of the tail pipe connecting sleeve to clamp the tail pipe 22 after it is inserted into the tail pipe connecting sleeve 2. One end of the second elastic arc clamping plate 12 is connected to the tail pipe connecting sleeve 2 to prevent the second elastic arc clamping plate 12 from separating from the tail pipe connecting sleeve 2.

[0022] A second screw mounting hole 14 pointing vertically to the third separation groove 15 is provided on the second elastic arc clamping plate 12, and a second threaded hole 16 corresponding to the second screw mounting hole 14 is provided on the outer circle of the tail pipe connecting sleeve 2. After the tail pipe 22 is inserted into the tail pipe connecting sleeve 2, a screw connected to the second threaded hole 16 is installed in the second screw mounting hole 14 to lock the second elastic arc clamping plate 12, thereby locking the tail pipe 22 and avoiding the problem of loosening. An axially extending second keyway 17 is provided in the inner concave of the tail pipe connecting sleeve 2 to facilitate the installation of the key block, which cooperates with the keyway on the outer circle of the tail pipe 22 to avoid the torsion problem of the tail pipe 22.

[0023] The tail pipe connecting sleeve 2 is concentrically connected to the gear ring 3, such as Figure 1 and Figure 2 As shown, a first flange 5 is provided at one end of the tail pipe connecting sleeve 2 pointing to the gear ring 1, and a second flange 4 corresponding to the first flange 5 is provided at one end of the gear ring 3 pointing to the tail pipe connecting sleeve 2. In this embodiment, bolts 6 are provided between the first flange 5 and the second flange 4 for fastening, so the structure is stable and easy to disassemble and assemble.

[0024] The synchronous pipe connecting sleeve 1 is arranged in the gear ring 3 and extends to the outside of the gear ring 3 along the axial direction of the gear ring 3. In the present embodiment, the synchronous pipe connecting sleeve 1 is provided with a gear 8 located in the gear ring 3. The synchronous pipe connecting sleeve 1 and the gear 8 adopt an integrated structure and can be made of steel with high structural strength.

[0025] like Figure 6 As shown, the gear ring 3 is provided with tooth grooves 20 corresponding to the gear 8 for synchronous rotation transmission. Figure 3 As shown, the tooth top surface of the gear 8 is an outwardly convex arc surface. The tooth top surface of the arc surface cooperates with the tooth groove 20, which can not only ensure the transmission of the tail pipe 22 and the synchronous pipe 21, but also adapt to the radial runout or slight swing of the synchronous pipe connecting sleeve 1 with the long length of the synchronous pipe 21, reduce the damage of the synchronous pipe 21 during the operation of the stranding machine, and thus extend the service life.

[0026] like Figure 2 As shown, a stop ring 7 is provided on the gear ring 3 and is located outside the gear 8. The stop ring 7 and the gear ring 3 are integrated. In this embodiment, the inner diameter of the stop ring 7 is larger than the outer diameter of the synchronous tube connecting sleeve 1, and the inner diameter of the stop ring 7 is smaller than the outer diameter of the gear. The axial travel of the gear 8 is limited by the cooperation between the stop ring 7 and the first flange 5, which can allow a slight axial movement of the synchronous tube connecting sleeve 1 and prevent the synchronous tube connecting sleeve 1 from falling off, and has high safety in use.

[0027] In summary, the adaptive connection assembly for the synchronous tube of a stranding machine pointed out in the present invention is easy to assemble, realizes the transmission of the tail tube and the synchronous tube, improves the adaptability to the radial runout or slight swing of the synchronous tube, meets the continuous and stable operation of the long length synchronous tube on the stranding machine, reduces the breakage problem of the synchronous tube, reduces the maintenance cost and downtime, thereby improving the production efficiency of the stranding machine for wire armoring.
