Description

Technical Field

[0001] The utility model belongs to the technical field of winch wire ropes, and in particular relates to a wire rope recovery and flushing device. Background Art

[0002] In the field of offshore oil and gas development, submarine pipeline laying is an important part of offshore oilfield engineering construction. The A&R winch system is one of the important equipment in the field of deep-sea oil and gas development. It is mainly used for abandoning and recovering submarine pipelines on a lifting pipe-laying vessel. At the beginning and end of the pipe-laying vessel laying the submarine pipeline or when the pipeline needs to be abandoned in bad weather, the steel wire rope on the A&R winch drum needs to be connected to the submarine pipeline head or the starting anchor cable, and the submarine pipeline abandonment and recovery operations are completed as the A&R winch is retracted and released.

[0003] Among them, the steel wire rope used in conjunction with the A&R winch is a key component. It is a multi-layer compacted strand steel wire rope with anti-rotation performance. Depending on the workload of the winch and the laying water depth, the steel wire rope diameter is between 60 and 135 mm, and the length is between 1000 and 3500 meters. The A&R winch steel wire rope is frequently used on pipe-laying vessels, with various load changes and long-term immersion in seawater environments. In the offshore pipeline construction project, the A&R winch steel wire rope will enter the water hundreds of times, and the length of the water entry reaches 2000 meters. Because seawater is highly corrosive to steel materials, steel wire ropes are prone to fatigue, wire breakage and rust due to long-term immersion in seawater, so each time the A&R steel wire rope is recovered from the sea, it will be rinsed with fresh water. Due to the lack of a matching cleaning device, ordinary water pipes are not thorough enough to rinse the surface of the steel wire rope, and the water stuck on the steel wire rope will also drip onto other equipment as the steel wire rope is recovered, causing corrosion to other equipment.

[0004] Therefore, it is urgent to design a wire rope recovery and flushing device to solve the problem that after the wire rope is recovered, the surface of the wire rope is not thoroughly flushed, causing corrosion to the wire rope and other equipment. Utility Model Content

[0006] In order to achieve the above-mentioned purpose, the specific technical scheme of the wire rope recovery and flushing device of the utility model is as follows:

A flushing section and a purge section are arranged in the circular inner wall 2. When the wire rope 9 moves, water is passed through the flushing section to flush the wire rope 9, and air is blown through the air intake section to purge the wire rope 9. In this embodiment, when the wire rope 9 is flushed during the movement of the wire rope 9, the wire rope 9 is firstly treated with water, and then the wire rope 9 is blown. The diameter range of the wire rope 9 applicable to this embodiment is 76 to 108 mm, which basically covers the A&R winch wire rope 9 used in domestic offshore pipe-laying vessels. The moving direction of the wire rope 9 is Figure 2 The direction shown by L1.

[0031] By passing the steel wire rope 9 through the circular inner wall 2, a plurality of through holes are opened on the circular inner wall 2, and a flushing section and a purging section are provided in the circular inner wall 2. When the steel wire rope 9 moves, water is passed through the flushing section to flush the steel wire rope 9, and air is blown through the air intake section to purge the steel wire rope 9. The steel wire rope 9 is flushed and cleaned, and at the same time, water adhering to the steel wire rope 9 will also be blown clean, which plays a role in corrosion protection for the steel wire rope 9 and also ensures that water drops on the uncleaned steel wire rope 9 fall on other equipment and corrode other equipment. Compared with manual water spraying and flushing using a water pipe, the steel wire rope recovery and flushing device has a simple structure and improves the flushing efficiency, especially the corrosion of the tensioner.

[0032] Further, if Figures 1 to 6 As shown, a water hole 3 and an air inlet 4 are provided on the circular housing 1.

[0039] The first shell 11 and the second shell 12 are installed on the wire rope 9 on the recovery path of the stern operation line, and the first shell 11 and the second shell 12 are buckled and connected together through the connector. After the installation is completed, the bracket is adjusted according to the angle of the wire rope 9, and the gap between the circular inner wall 2 of the wire rope recovery and flushing device and the wire rope 9 is adjusted to be uniform, and then the waterway and compressed air are connected. As the wire rope 9 is recovered and moved, the high-pressure water and compressed air in the chamber are evenly sprayed from the water hole and the air hole, and the wire rope 9 passing through is first flushed with water and then purged with compressed air, and the wire rope 9 is cleaned.
