A kind of winch traction wheel disc for marine vessel

Abstract

The invention relates to the winch traction equipment technology field and discloses a winch traction wheel disc used for a marine ship. An installation base is included. Middle portions of two sidesof an inner cavity of the installation base are fixedly connected with two ends of an inner traction disc, the two ends of the inner traction disc movably sleeve a conversion mechanism, and an upper end and a lower end of the conversion mechanism are fixedly connected with an upper side and a lower side of one end of an outer traction disc wrapping a periphery of the inner traction disc. By usingthe winch traction wheel disc used for the marine ship, the inner traction disc and the outer traction disc are arranged so that a wound and dragged rope can be conveniently distributed in a single layer. Compared with an existing winch wheel disc, by using the winch traction wheel disc of the invention, when the rope is used for winding and pulling an object, the ropes on each layer cannot be extruded and scraped; then, a rust-proof coating on a surface of the traction rope can be effectively protected, a corrosion phenomenon caused by seawater corrosion is avoided, connection strength of thetraction rope is ensured and safety is high; and meanwhile a service life of the traction rope is prolonged.

Description

technical field [0001] The invention relates to the technical field of winch traction equipment, in particular to a winch traction wheel for marine vessels. Background technique [0002] The winch traction mechanism is an important device on a marine vessel. It mainly uses the traction rope to drag objects. When dragging objects for long distances such as salvage and rescue, it will inevitably cause a certain section of the traction rope to sink Below the sea surface, therefore, the traction ropes used by marine vessels need to be sprayed with anti-rust paint on their surfaces to prevent seawater erosion and ensure the connection strength and service life of the traction ropes. [0003] However, when the existing winch traction mechanism is pulling an object, since the ropes will all be wound on the wheel disc and will be subject to a huge reaction force from the object, the ropes will squeeze each other and cause scratches when winding around the pulling object. , and lead...

AI Technical Summary

Problems solved by technology

[0005] The invention provides a winch traction sheave for marine ships, which can not squeeze or scratch the anti-rust coating on the surface of the rope when winding the traction object to ensure that the metal structure inside the traction rope will not be eroded by seawater, The advantages of long service life and high safety solve the problem that when the existing winch traction mechanism is pulling the object, because the rope will be completely wound on the wheel and will be subjected to the huge reaction force of the object, which will cause the rope to be wound when pulling the object. The ropes will be squeezed and scratched, and the anti-rust coating on the surface of the traction rope will be damaged, causing the internal metal material to be eroded by seawater and corroded, which greatly affects the traction rope. The connection strength and its service life are high, and the internally corroded traction rope is difficult to be found. If you drag a heavy object without knowing it, there is a great potential safety hazard.
