A marine power-assisted rotating cable guide device

Abstract

The invention provides a marine power assisted rotary cable guide device. The device comprises a hollow shaft assembly, a swing pulley assembly, a roller bracket (11), a roller (12) and a drive motor,the device is characterized in that the hollow shaft assembly comprises a fixed frame (6) and a hollow shaft (8) rotatably mounted on the fixed frame (6), the swinging pulley assembly comprises a rotating frame (1) and a pulley (2) rotatably mounted on the rotating frame (1), the roller bracket (11) is fixedly mounted on a deck, one end of the rotating frame (1) is fixed at one end of the hollowshaft (8), the rotating frame (1) can be rotated along with the hollow shaft (8), after passing through a through hole of the hollow shaft (8), a cable bypasses a rope groove of the pulley (2) to enter into the sea, and the rotation axis of the hollow shaft (8) is located on the symmetrical center plane of the rope groove of the pulley (2). The marine power assisted rotary cable guide device is provided with the pulley capable of deflecting with a guiding cable, the water entry direction of the cable is dynamically adjusted and rotated to reduce the friction of the cable, and device has the advantages of being convenient to maintain, flexible in rotation, simple and practical.

Description

technical field [0001] The invention belongs to the technical field of marine equipment, and more specifically relates to a marine power-assisted rotating cable guide device. Background technique [0002] China is rich in offshore oil and gas resources and seabed mineral resources. Going into the ocean is a key strategic decision of the country, and it is also an inevitable need to become a maritime power. The development of marine deep-water geophysical exploration, drilling, logging and marine engineering equipment urgently needs to solve various related problems. Positioning control is required for construction operations such as semi-submersible platforms, multi-cable geophysical exploration vessels, and large offshore operating vessels. In terms of positioning methods, DP dynamic positioning and mooring positioning are generally used. For the mooring and positioning operation method, it involves mooring and positioning anchor winch equipment, mooring and positioning a...

Problems solved by technology

With long-term ship navigation and offshore engineering operations, the fairlead equipment is subjected to various sea waves and moisture erosion, so that the cable is constantly affected by the irregular swinging lateral force during work, thereby compressing the fairlead equipment and making the guidewire The phenomenon of deflection, corrosion and increased frictional resistance of the cable equipment makes the rotation inflexible, resulting in long overall operation time and low work efficiency, which affects the anchor positioning effect and the safety of the mooring positioning system
