Technical Field
[0001] This utility model belongs to the field of marine engineering technology, and in particular relates to a wire rope washing device. Background Technology
[0002] Currently, marine engineering vessels are equipped with towing and lifting devices, typically large winches, which tow and lift equipment by winding and unwinding steel wire ropes. Because the steel wire ropes come into contact with seawater, their surfaces accumulate salt and dirt over time. Directly winding up the wire ropes can lead to corrosion, affecting their stability and safety, and reducing their lifespan. Furthermore, the contact between the wire rope and mechanisms such as drums and pulleys can also cause corrosion of these components, affecting the normal operation and safety of the winch. Utility Model Content
[0003] This utility model provides a wire rope washing device, which aims to solve the problem that wire ropes come into contact with seawater, and their surfaces become covered with salt and dirt. Long-term use and directly retracting the wire ropes will lead to corrosion.

The inner end of the water inlet pipe is connected to an annular pipe concentric with the shell, and multiple nozzles facing the center are spaced apart on the inner annular surface of the annular pipe.
[0005] A dry gas sealing ring is provided at each end of the inner cavity of the housing. The steel wire rope passes through a set of guide wheels and dry gas sealing rings into the housing and exits from the dry gas sealing ring and guide wheel at the other end.
[0006] Preferably, a water outlet pipe is provided on the side of the shell surface opposite to the water inlet pipe, and the water outlet pipe is connected to the inner cavity of the shell.
[0007] Preferably, a connecting bracket is provided on the surface of the housing.
[0008] Preferably, the housing comprises two semi-cylindrical shells, which are hinged together and locked with bolts.
[0009] Beneficial effects
[0010] Compared with the prior art, the beneficial effects of this utility model are as follows: The wire rope washing device of this utility model, by setting an annular pipe and setting multiple nozzles on the annular pipe to wash the surface of the wire rope, washes away the salt and dirt on the surface of the wire rope, avoids the wire rope from being corroded, extends its service life, and at the same time can avoid damage to the winch components, thus improving the overall safety and stability of the winch.

[0014] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.
[0015] Please see Figure 1-2 This utility model provides a technical solution: a wire rope washing device, including a cylindrical shell 1, a set of guide wheels 2 for guiding the wire rope 3 at both ends of the shell 1, a water inlet pipe 5 extending into the inner cavity of the shell 1 on one side of the shell 1, an annular pipe 6 concentric with the shell 1 connected to the inner end of the water inlet pipe 5, and a plurality of nozzles 7 facing the center arranged at intervals on the inner annular surface of the annular pipe 6.
[0016] Each set of guide wheels 2 includes two guide wheels 2 arranged opposite each other, forming a channel between them for the steel wire rope 3 to pass through, guiding the steel wire rope 3 and reducing friction. Each guide wheel is mounted by a mounting bracket fixed to the surface of the housing, and the guide wheel and the mounting bracket are rotatably connected.
[0017] The annular pipe 6 is an open pipe with both ends sealed, which makes it easy to remove the wire rope 3 from the annular pipe 6 in case of failure.
[0018] There are three nozzles 7, installed at 120° intervals between each pair. More nozzles can also be installed, arranged at even intervals, all facing the center, to ensure that the outer ring surface of the wire rope cross-section is fully rinsed.
[0019] A dry gas sealing ring 4 is provided at each end of the inner cavity of the housing 1. The steel wire rope 3 passes through a set of guide wheels 2 and dry gas sealing ring 4, enters the housing 1, passes through the annular tube 6, and exits from the dry gas sealing ring 4 and guide wheel 2 at the other end.
[0020] In this embodiment, since through holes need to be formed at both ends of the housing 1 for the steel wire rope 3 to pass through, water will flow out from both ends of the housing 1 and cause leakage. Therefore, two dry air sealing rings 4 are set at both ends of the inner cavity of the housing 1. The area between the two dry air sealing rings 4 is the flushing section. The steel wire rope 3 passes through the two dry air sealing rings 4. The dry air sealing rings are ventilated, and an air seal is formed at the joint between the steel wire rope and the dry air sealing ring 4 to prevent water from flowing out from the center of the dry air sealing ring 4. Both dry air sealing rings 4 have an air seal formed at one end inside, and the flushing water is sealed in the flushing section and cannot flow out from both ends.
[0021] The inner cavity of the housing 1 has mounting positions at both ends that are adapted to the dry gas sealing ring 4, so that the dry gas sealing ring 4 fits tightly against the inner wall of the housing 1, and a sealing ring is provided between the outer surface of the dry gas sealing ring 4 and the inner wall of the housing 1 to prevent water from flowing to both ends.
[0022] Furthermore, a water outlet pipe 8 is provided on the side of the surface of the housing 1 opposite to the water inlet pipe 5, and the water outlet pipe 8 is connected to the inner cavity of the housing 1.
[0023] In this embodiment, the water outlet pipe 8 is connected to the rinsing section, and the water after rinsing is discharged through the water outlet pipe 8 to avoid leaving it in the housing 1 and causing salt to re-adhere to the wire rope.
[0024] During installation and use, ensure that the water outlet pipe 8 is at the bottom to facilitate the drainage of water from inside the housing 1 and prevent water accumulation inside the housing 1.
[0025] Both the inlet pipe 5 and the outlet pipe 8 can be connected to a water pump for water supply and drainage. The water used for rinsing should be fresh water or desalinated seawater.
[0026] Furthermore, a connecting bracket 9 is provided on the surface of the housing 1. It can be used in conjunction with the winch rope output component.
[0027] Furthermore, the housing 1 comprises two semi-cylindrical shells, which are hinged together and bolted together. Two dry gas sealing rings 4 are fitted between the inner walls of the two shells at both ends. A water inlet pipe 5 and a water outlet pipe 8 are respectively installed on one of the shells. Two guide wheels from a set of guide wheels 2 can also be installed on the two shells respectively. By opening the two shells, the interior can be cleaned and maintained, preventing salt adhering inside from corroding the components.
[0028] The working principle and usage process of this utility model are as follows: After the utility model is installed, the wire rope 3 passes through a set of guide wheels 2 and a dry air sealing ring 4 at the rear end, and then through an annular pipe 6. The nozzle 7 sprays high-pressure water to evenly rinse the surface of the wire rope, washing away the salt and dirt on the surface of the wire rope and cleaning the wire rope. After rinsing, the wire rope passes through the dry air sealing ring 4 at the front end and a set of guide wheels 2 at the front end, and is wound up by a winch.
[0029] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
