Description

Technical Field

[0001] The invention relates to an improvement of a hose wear reduction technology, belongs to the field of liquid cargo transportation, and in particular to a stern hose recovery and slag discharge device. Background Art

[0002] After the liquid cargo transportation operation is completed, when the winch is performing the pipe retracting operation, a stern hose friction reduction device will be installed in front of the winch. This device has a guiding effect on the hose released or retracted by the liquid cargo transportation winch, and can reduce the friction loss between the hose and the ship's side, thereby effectively improving the use of the hose, extending its service life, and avoiding the occurrence of dangerous operations.

[0003] However, after the liquid cargo delivery winch completes the delivery operation, there will still be residual liquid cargo or air inside the hose. When the hose is recovered, the residual liquid cargo or air in the hose will increase the thickness of the hose wrapped around the liquid cargo delivery winch, which will cause friction between the hose and the deck. In addition, during the hose winch recovery operation, since the hose is generally long, the recovery takes a long time, which further aggravates the friction between the hose and the bottom mounting base of the liquid cargo delivery winch, increasing the risk of damage to the hose, and even causing damage to the hose in severe cases. However, the existing stern hose friction reduction device can only reduce the friction of the hose during the process of dragging the hose back to the winch, but cannot solve the problem of the hose becoming thicker due to residual liquid cargo or air, thereby causing friction with the deck.

[0004] A Chinese patent application with application number CN202311083091.5 and application date August 28, 2023 discloses a hose wear reduction device, comprising a bracket, an upper roller and a lower roller; the bracket comprises a left wall, a bottom wall and a right wall connected vertically in sequence; a locking groove and a step structure are provided at the top of the right wall; the upper roller comprises an upper central axis and an outer surface of the upper roller wrapped around the outside of the upper central axis, a butterfly nut is screwed on one end of the upper central axis passing through the locking groove, and the other end of the upper central axis is movably connected to the top of the left wall; the lower roller is fixedly connected to the left wall and the right wall, the butterfly nut is first loosened so that the upper central axis can be rotated upward to leave the locking groove, and the top of the device is connected to the outside world. After the hose is placed at the connection point, the upper central axis is rotated downward to connect to the locking groove, and then the butterfly nut is tightened to restrain the hose and confine the hose to the device; there is rolling friction between the outer surface of the hose and the roller, which greatly reduces the friction force, but the above scheme does not solve the problem that residual liquid cargo or air causes the hose to become thicker and thus rub against the deck.
