Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of cable processing, and particularly relates to a cage type cabling device. BACKGROUND

[0002] China's new energy is developing rapidly, especially in wind and solar power generation, which is growing significantly. According to incomplete statistics, 14388 new installations were added in 2024, with a capacity of 8699 million kilowatts, an increase of 9.6% year on year. Among them, the land wind power added 8137 million kilowatts of installed capacity, accounting for 93.5% of the total installed capacity, and the offshore wind power added 561.9 million kilowatts of installed capacity, accounting for 6.5% of the total installed capacity. With the rapid development of new energy, the cable products used are also constantly updated and iterated, and multi-functional integration has become an important technical development direction of cables, that is, more line cores with special functions need to be integrated in one cable.

[0003] At present, the related equipment for cable core cabling basically only has six first cradles, and six first cradles are provided on the six first cradles, such as a commonly used cage type cabling machine, a disc stranding machine, etc. Figure 1 As shown in a top view of a commonly used cage type cabling machine, the cage type cabling machine is provided with six first cradles. The commonly used first cradle has a single-arm cradle, a double-arm cradle, etc., Figure 1 The double-arm cradle is adopted. The cage type cabling machine is sequentially provided with a front section winch, a middle section winch and a rear section winch along the length direction, and three first cradles are arranged between the front section winch and the middle section winch and between the middle section winch and the rear section winch, and the connecting shafts at both ends of the first cradle are respectively rotationally connected with the winches on the left and right sides. The device is also provided with an external pay-off rack, and the most central shaft of the external pay-off rack is hollow and can pass through a line core. The cage type cabling machine can produce seven-core cables. Under the driving of the driving device, the front section winch, the middle section winch and the rear section winch rotate together. The front section winch is provided with a planetary gear untwisting system, and the planetary gear untwisting system is connected with the connecting shafts of the first cradles. While the first cradles rotate with the winches, the planetary gear untwisting system drives the first cradles to rotate, so that the pay-off discs of the first cradles are always in a horizontal state during the rotation of the winches, thereby enabling the first cradles to have an untwisting function. The connecting shafts of the first cradles are each provided with a pay-off hole, the pay-off hole penetrates the winch on the downstream side thereof, and the wires on the pay-off discs of the first cradles penetrate the pay-off hole and extend into the downstream side of the distribution disc. However, the commonly used cage type cabling machine currently only has six cradles, and cannot meet the cabling processing needs of more than seven-core cables. SUMMARY

[0004] In view of the existing technical problems, the present application aims to provide a cage type cabling device which can solve the technical problem that the cage type cabling machine in the prior art cannot meet the cabling processing needs of more than seven-core cables.

[0005] To achieve the above object, the technical scheme adopted by the present application is:

[0007] The cage type cabling device of the present application is improved on the basis of the existing cage type cabling machine. According to the requirements of the number of cable cores to be processed and the installation space limitation on the rear section winch, one or more second cradles are added to the rear section winch, and the second cradles will rotate with the existing rear section winch. If nine-core cables need to be processed, and the existing cage type cabling machine can process seven-core cables, two second cradles need to be added. By arranging a first sprocket on the connecting shaft of the existing first cradle and a second sprocket on the connecting shaft of the added second cradle, and connecting the second sprocket and the first sprocket through a chain transmission, the added second cradle is linked with the planetary gear untwisting system of the existing cage type cabling machine, so that the added second cradle and the existing first cradle both have untwisting functions. When the cage type cabling device of the present application works, the wires on the wire reel of the second cradle penetrate through the second cradle wire feeding hole into the downstream side of the wire distribution disc. In the process of rotating with the rear section winch, the existing planetary gear untwisting system of the cage type cabling machine drives the first cradle to rotate at the same time, and drives the second cradle to rotate through the first sprocket, the chain and the second sprocket, so that the wire reels of the second cradle and the existing first cradle always maintain a horizontal state during cabling, thereby making the movement of the second cradle consistent with that of the existing first cradle. The cage type cabling device of the present application, without affecting the functions and performance of the existing equipment, can meet the cabling needs of special core cable products by adding a second cradle, which is more practical and cost-effective than the standard large cradle. The cage type cabling device of the present application realizes the untwisting function of the second cradle through the sprocket transmission system, and the second cradle and the existing first cradle untwist synchronously, ensuring the consistency of the untwisting effect and meeting the core technical requirements of the cabling process of special cable products.
