Steering rope guider

Abstract

The invention discloses a steering rope guider, which comprises a fixing supporting base, a rotary pulley frame and a pulley group; the fixing supporting base is installed at an installing face. The rotary pulley frame is rotationally installed on the fixing supporting base, and the rotary pulley frame is rotated in a first plane. The pulley group comprises two pulleys, and the pulley group is rotationally installed on the rotary pulley frame, and rotated in a second plane; rope grooves of two pulleys are aligned mutually to form a steel rope channel; a steel rope is located in the steel rope channel, wherein the installing face, the first plane and the second plane are perpendicular to each other. In the steering rope guider, the steel rope can cross through a pair of pulley groups which form a balance couple; the pulley group can freely rotate so that the rope grooves are synchronous to the direction of the steel rope, so as to adapt to the angle change of the steel rope.

Description

technical field [0001] The present invention relates to marine mechanical equipment, more specifically, to a marine positioning anchor winch. Background technique [0002] Various large-scale engineering ships, such as pipe-laying ships and crane ships, are equipped with multiple ship-moving anchor winches. The ship-moving positioning anchor winch is used to position the ship. Every time the steel wire rope of the ship-moving positioning anchor winch is thrown into the water from the ship, the direction is uncertain, and as the anchor winch retracts and unwinds the steel wire rope, the engineering ship starts to move , the direction angle of the wire rope is also changing all the time. The angles of the pulleys of the existing ship-moving anchor winches are all fixed. If the angle of the wire rope changes, there will be an offset between the wire rope and the pulley, and the offset may cause friction. Unnecessary wear and tear on wire ropes and pulleys.

AI Technical Summary

Problems solved by technology

However, this method does not solve the problem fundamentally. The pulley itself is still fixed, and the limit of the angle of the wire rope by the idler is relatively limited. It can only be applied to wire ropes with basically fixed angles or wire ropes with small angle changes. Heavy-duty anchor winches with large variation range and large load are not suitable

The steel wire rope of the heavy-duty anchor winch changes greatly in the angle of the rope in the water, resulting in serious axial friction between the steel wire rope and the idler roller. When the roller deformation is large, it will affect the normal work and even damage the roller
