An R6 class mooring chain underwater guide sprocket

Abstract

The invention provides an R6 class mooring chain underwater guide sprocket, which is characterized by comprising a roller tooth, an arc-shaped folded surface chain groove, a guide chain groove, a baffle plate, a polygonal lightening groove and a center hole in an integral structure; and the R6 class mooring chain underwater guide sprocket comprises a roller tooth, an arc-shaped folded surface chain groove, a guide chain groove, a baffle plate, a polygonal lightening groove and a center hole. The guide chain groove is arranged in the middle of the guide sprocket, and the guide chain groove is structured as an annular groove concave downward on the wheel surface; The wheel surface of the guide sprocket wheel is provided with a plurality of roller teeth with an integral structure and arc-shaped folded surface chain grooves connecting the roller teeth with the integral structure, and the roller teeth and arc-shaped folded surface chain grooves with the integral structure are evenly distributed on the wheel surfaces on both sides of the guide chain grooves; The baffle plate is located on the outside of the roller teeth and the arc-shaped folded surface chain groove which are in an integral structure. On the premise of satisfying the overall strength of the roller, the invention reduces the overall weight of the roller as much as possible, reduces the risks of chain disengagement, tooth breakage and chain clamping of the common anchor chain under the action of the mooring chain, and strengthens the coupling between the anchor chain and the roller. Compared with the traditional sprocket, the sprocket can bear larger load and has stronger adaptability.

Description

technical field [0001] The invention relates to the technical field of large-scale marine engineering equipment, in particular to an underwater guide sprocket of a mooring chain. Background technique [0002] Large-scale marine structures use mooring chains. In order to adjust the angle and direction of the mooring chains and reduce the wear and tear of the mooring chains, it is necessary to install a matching chain guide device on the legs. [0003] At present, there is no manufacturer in China that designs and produces high-standard underwater chain guide devices for mooring chains, and only Rolls-Roycs in the UK and IHC in the Netherlands can design and produce them abroad. Chinese patent CN106379492B discloses a marine positioning and mooring system for marine engineering equipment and its use method, including: main winch, double guide sprocket, auxiliary winch, mobile guide sprocket and several chain outlets; among them, the marine engineering that needs positioning T...
