Embodiment 1

[0028] Such as Figure 1-3 As shown, according to an embodiment of the present invention, a double-machine series twisting method for a large cross-section concentric conductor of a submarine cable, the method includes the following steps:

[0029] 1) Put the ordinary 91-core concentric conductor prepared by stranding machine one 5 into the entrance of stranding machine two 9 through steering mechanism one 6, electrical synchronization controller 7 and steering mechanism two 8 in sequence;

[0030] 2) Set the 6-core stranded body and the 12-core stranded body to the same speed and direction of rotation, put the 6-core stranded body into the 6-core synchronous threading tube 10, and then pass them into the 12-core stranded body's wire-passing tube together , making 18-core combined twisted body;

[0031] 3) Set the 18-core combined stranded body and the 18-core stranded body prepared in step 2) to the same speed and direction of rotation, and put the 18-core combined stranded ...

Embodiment 2

[0039] A double-machine serial twisting method for large-section concentric conductors of submarine cables, said method comprising the following steps:

[0040] 1) Lead out the ordinary 91-core concentric conductor prepared by stranding machine 1 through the traction wheel and store it on the finished wire take-up reel or outer receiving wire tray, and then pull the 91-core concentric conductor to the stranded wire again The entrance of Machine 1 5;

[0041] 2) Set the 6-core stranded body and the 12-core stranded body to the same speed and direction of rotation, put the 6-core stranded body into the 6-core synchronous threading tube 10, and then pass them into the 12-core stranded body's wire-passing tube together , making 18-core combined twisted body;

[0042] 3) Set the 18-core combined stranded body and the 18-core stranded body prepared in step 2) to the same speed and direction of rotation, and put the 18-core combined stranded body into the 18-core synchronous threadi...

Abstract

The invention discloses a two-engined series twisting device and method for a large-section common core conductor for a submarine cable. The device comprises two 91-core wire twisting machines. The two-engined series twisting device is characterized in that the two wire twisting machines are arranged face to face in parallel; workpieces of the two wire twisting machines are opposite in direction; two groups of steering wheels are arranged between the rear surface of a traction wheel of the first wire twisting machine and a wire inlet of the second wire twisting machine; an electrical synchronous controller is arranged between the two groups of steering wheels; a group of 6-core synchronous threading pipes are arranged at the center of a 12-core twisting body of the second wire twisting machine; a group of 18-core synchronous threading pipes are arranged at the center of an 18-core twisting body; and a group of 12-core synchronous threading pipes are arranged at the center of a 30-core twisting body of the second wire twisting machine. The two-engined series twisting device and method have the beneficial effect that the manufacturing problem of over 1,000mm<2> large-section common core conductors for the submarine cable is solved.

Description

technical field [0001] The invention relates to the technical field of manufacturing cable concentric conductors, in particular to a double-machine serial twisting device and method for large-section concentric conductors of submarine cables. Background technique [0002] The conductors of submarine cables at home and abroad have waterproof requirements, and the same-core conductors have more advantages in waterproof performance than split conductors. Conductor 1000mm 2 For the above submarine cables, only single-core submarine cables can use split conductors, and three-core submarine cables must use concentric conductors. The so-called co-core conductor means that each layer is twisted from the same core layer, and the number of cores in the outer layer is 6 more than that of the adjacent inner layer. [0003] At present, the commonly used stranding equipment in China is mostly six-layer 91-core (1+6+12+18+24+30), and the stranding cross-section of the same-core conductor...
