Flexible armor structure for protecting cable and assembly method

Abstract

The invention discloses a flexible armor structure for protecting a cable and an assembly method, and the structure mainly comprises a flexible armor interface, a flexible armor outer ring, a flexiblearmor inner tube, a cable structural part, and a flexible armor inner tube and a flexible armor outer ring which are sleeved outside the cable structural part and are hooked and embedded end to end.The two ends of the flexible armor outer ring and the two ends of the flexible armor inner tube are fixed through flexible armor connectors, and the flexible armor connectors are connected with equipment in a butt joint mode. According to the invention, the multiple inner tubes and the multiple outer tubes are buckled, bending and twisting of the flexible armor can be achieved, the bending lengthof the flexible armor can be adjusted, and finally flexible connection is achieved; the manufacturing is simple and can be realized in a common machining workshop; under the condition that bending torsional deformation is met, load acting force in the axial direction can be achieved; and strong cable protection capability is achieved.

Description

technical field [0001] The invention relates to the field of cable protection, in particular to a flexible armor structure and an assembly method for cable protection. Background technique [0002] With the development of society, human beings need to continuously expand their living space, resulting in the need for continuous excavation of natural materials. Therefore, in order to strive for a larger living space, human beings are forced to actively face the extremely harsh external environment. Therefore, along with it, the production equipment needs to accept challenges such as going into the mountains, going up to the sky, going into the ground, and going down to the sea. The cables are an important part of these devices, and the quality of their protection is related to whether the devices can operate reliably. [0003] The insulation layer of the bare cable surface exposed in the water in the marine towing system is often bumped, scratched, and torn by unknown object...

AI Technical Summary

Problems solved by technology

[0005] The shortcoming of prior art has following two points: (1) existing bellows technical structure is complicated, and manufacturing process is complicated

For example: metal corrugated pipes require a special special equipment to process the metal and then wind it. At the same time, the interface treatment is also a complicated process; the corrugated pipes of the braided structure require special braiding machines, which are difficult for general machining workshops.

(2) The bearing capacity in the axial direction is small, and it can be used under normal circumstances, but when force is applied in the axial direction, the interface is easy to disengage, and the metal bellows part is generally thinner in order to achieve bending and torsional deformation , easy to break
