Universal bearing device for connecting steel cable and outboard surveying device and manufacturing method thereof

Abstract

The invention discloses a universal bearing device for connecting a steel cable and an outboard surveying device. The universal bearing device for connecting the steel cable and the outboard surveying device comprises a distorting-resistant portion, a bearing portion, a rotating portion and a device mechanical connecting portion and is further provided with a junction box and an oil compensator. A manufacturing method of the universal bearing device for connecting the steel cable and the outboard surveying device comprises the steps that (1) an operation cable is pretreated; (2) the bearing portion is manufactured; (3) the rotating portion is manufactured and installed; (4) the junction box is manufactured and installed. The universal bearing device for connecting the steel cable and the outboard surveying device is suitable for connecting the steel structural operation steel cable used in the marine surveying process and the outboard marine surveying device. The bearing device is provided with a mechanical connecting bearing connector, a power source connecting bearing connector and a signal connecting bearing connector, connection is safe and reliable, the failure rate of the marine surveying device and losses caused by fracture of the steel cable are reduced, the universal bearing device for connecting the steel cable and the outboard surveying device is suitable for all the steel structural operation steel cables such as the armor photoelectric composite cable, the armor coaxial cable and the steel cable, the universality is extremely high, the universal bearing device for connecting the steel cable and the outboard surveying device is particularly suitable for connecting the large-scale deep marine surveying device and the steel cable and is an excellent device for connecting various marine surveying devices and the tail end of the steel cable.

Description

technical field [0001] The invention belongs to the technical field of marine detection equipment, in particular to an armored photoelectric composite cable, armored coaxial cable, steel cable and other steel structure working cables used in marine surveys, referred to as steel cables connected to outboard survey equipment. A universal connection and load-bearing device, referred to as a universal load-bearing device, and a manufacturing method of the device. Background technique [0002] In the ocean, especially in deep sea and ocean survey operations, various steel cables and outboard survey equipment are the most important and indispensable equipment in survey operations. Due to the many types of survey equipment involved, the connection devices between steel cables and various survey equipment often do not have unified mechanical, power and signal interfaces, and there are many problems in the process of using and replacing different survey equipment. For example, the l...

AI Technical Summary

Problems solved by technology

Such as: the load-bearing capacity of the connection device is insufficient, causing the equipment to be lost or cannot be recovered; the watertight connectors of the connection head are inconsistent, thus restricting the scope of use of the outboard survey equipment

In addition, when the investigation equipment is working underwater, in order to ensure that it works in a stable state after landing on the seabed, it is necessary to release a certain length of steel cable, which often causes the long steel cable to bend and accumulate, which is easy to generate torsional force. During the retraction period, the steel cable will vibrate, and because the movement of the traditional connection load-bearing device is limited, the impact force received is relatively large, and the connection part is continuously in a state of fatigue motion, which is very easy to damage or break

At the same time, it also seriously affects the operation safety of the investigation equipment.
