Problems solved by technology

As far as the conventional single winch is concerned, if the retracted cable is too long and the tension is too large, it will inevitably cause chaotic layers and buckle or even crush the cable (if the retracted and retracted armored cable will cause core wire breakage and insulation damage) and water leakage), and it is difficult to provide greater tension

Embodiment Construction

[0020] The present invention will be described in further detail below in conjunction with the accompanying drawings and embodiments.

[0021] The present invention is a self-contained unit, installed between the original winch and retractable equipment, and forms a retractable system together with the original winch. It adopts double drive sheave structure, as shown in Figure 1, its structure consists of base 1, fairlead 2, cantilever support 3, main frame 4, reinforcement frame 5, armored umbilical cable 6 or steel wire rope, drive sheave 7 , an oil motor brake assembly 8, a planetary reducer 9, and a support bearing 10, wherein:

[0022] The base 1, the cantilever bracket 3, the main frame 4, and the reinforcing frame 5 are assembled together by welding process to form an overall frame, and these components all adopt a box-shaped structure; the base 1 is the basic frame of the device, and other purchased The parts are all welded and installed on this basic frame; the main ...

Abstract

The tension magnifying winch consists of pedestal, cable guide device, cantilever rack, main frame, reinforcing frame, armoured umbilical cable, driving grooved pulley, oil motor brake assembly, planetary reducer and support bearing assembly. The pedestal, the cantilever rack, the main frame and the reinforcing frame are assembled to constitute the integral frame; and the driving grooved pulley is connected to the main frame via the planetary reducer and connected to the cantilever rack via the support bearing and is driven with the oil motor via the planetary reducer. The present invention changes the tension magnifying coefficient through altering the annular groove number in the driving grooved pulley, and is set between the single winch and the releasing device for deep sea and heavy load underwater apparatus.

Description

technical field [0001] The invention relates to the retractable technology of underwater equipment and underwater robot umbilical cables, in particular to a tension amplifying winch which is especially suitable for retracting deep sea and heavy-duty underwater equipment. Background technique [0002] The 21st century is a century for human beings to develop and utilize the ocean. As the last undeveloped area that human beings know little about, the deep sea area is rich in resources, so all countries in the world have invested heavily in the investigation and development of deep sea resources, resulting in deep sea underwater robots, deep seabed sampling equipment, etc. High-tech facilities such as mining equipment for deep-sea mineral resources have developed rapidly. These devices have some common characteristics, such as large working depth and heavy weight. For the retraction of these devices, the winch is required to have the ability to retract and retract long armore...
