It includes.

Step S100 cuts the wire rope, step S110 checks the wire rope damage, step S120 binds both ends of the wire rope cutting part with wire, and step S130, if there is a wire rope damage part, the upper part of the damage part is the primary part. Cut. At this time, care should be taken as the wire may be loosened when cutting.

Step S200 inserts a new socket into the wire rope.

In step S300, to process the wire rope end, step S310 allows the depth of the socket to be about 80 mm. S320 step is to tie the wire 70mm ~ 100mm from the end of the wire rope. Step S330 is a second cut wire rope. Step S340 by using a pliers, loosen the strand and the wire twist of 70mm wire rope end. S350 step is to bend the end of the loose wire 10mm 90 degrees using a pliers.

Step S400 is to put the zinc rod in the container and heat it with a torch to melt. The container is continuously heated in the middle of the operation to remove impurities.

Step S500 processes the chemicals in the wire area. The drug is hydrochloric acid (HYDROCHLORIC ACID 36.4%) zinc chloride (ZINC CHLOLIDE), step S510 is first washed with hydrochloric acid. Step S520 is a second wash with fresh water. S530 step is washed three times with thinner. Step S540 dissolves zinc chloride in water.

S770 step is cooled slowly at room temperature when the heated zinc at the top end of the socket is raised convexly.

Referring to Figure 11 (a) to Figure 12 (h) it will be described in detail the wire socket operation sequence as follows.

The wire socket work takes about 3 ~ 4 hours, and the wire socket working condition should be very calm at sea and less fluctuations of the ship during berthing.

Wire rope is an element made by gathering wires drawn from carbon steel material, twisting them into strands, and winding the strands at a constant pitch around the core.

The terminal processing of the wire rope includes a socket, a timble, a wedge, an eye splice, a clip, and the like. The terminal processing of the present invention corresponds to a socket processing method. do.

The wire socket is provided with a hole through which the wire rope can penetrate, and a pullable hanger (Fig. 11 (a)).

First, the wire rope cut part is aged (Fig. 11 (b)), the wire rope end is cut first (Fig. 11 (c)), and the wire rope secondary cut part is aged (Fig. 11 (d)). ), The wire rope is cut twice (FIG. 11 (e)). Loosen the strand of cut and insert it into the wire socket (FIG. 11 (f)).

It is desirable to check for damage to the cut after cutting the wire rope. If the diameter reduction of the wire rope exceeds 7% of the nominal diameter it may be considered damaged. If a damaged part is present, there is a possibility that a large tensile force is generated in the joining and coupled sockets of a subsequent step, so that it is vulnerable, and it is necessary to cut the damaged part beforehand.

The wire socket is preferably in the form of a closed socket. Although the specific size of the closed socket is not limited, it is preferable to use a socket in which an inverted truncated conical hole in which the diameter gradually decreases toward the bottom of the socket inner hole is created. The wire socket may be carbon steel and may be forged or cast.

After cutting the wire rope, the cut may be first wound through a linear material, and then the insertion may be first performed in the socket so that the wire rope end portion remains to some extent, and then the winding step to be described below may be performed. After cutting the wire rope, the method may further include winding a predetermined spaced portion from the cut portion in the wire rope length direction through the linear material. The linear material may be wire, thread, rope, rope, etc., preferably galvanized wire. The winding step is preferably wound in a portion 7 to 10 times the distance from the cut in the wire rope length direction relative to the wire rope diameter. Winding is made in this range can be securely fastened between the wire rope and the socket through the heat treatment and melt injection of the next step.

Before the wire socket is inserted into the wire rope, the strand of the wire rope cut may be bent at an angle of 40 ° to 90 ° with respect to the wire (FIG. 12 (a)). The wire rope cut in this angle range can be stably fixed in the wire socket. At this time, it is preferable to bend the strand region 1 to 2 times the diameter of the wire rope from the cut portion.

Before the wire socket is inserted into the wire rope, the wire rope cut may be subjected to acid treatment, distilled water washing, and organic solvent washing ((Fig. 12 (b)).) The acid treatment may use hydrochloric acid or nitric acid, and the like. The hydrochloric acid may be used at a concentration of 30% to 40% The organic solvent may include at least one selected from the group consisting of acetate ester, toluene, butanol and combinations thereof. To remove foreign substances in the wire rope, to facilitate the bonding with the zinc melt to be made in the next step, and to be resistant to impact and corrosion during bonding (Fig. 12 (c)).

Insertion of the wire socket of the wire rope (Fig. 12 (d)) may be performed so that the unfolded strand of the wire rope is fully inserted into the hole in the wire socket (Fig. 12 (e)).

Next, the inserted socket is heat treated (FIG. 12 (f)), and a zinc melt is introduced into the inserted portion (FIG. 12 (i)).

Before the heat treatment, the stretched strand ends of the wire rope inserted through the heating means may be heat treated so that the strand ends are rounded. The heating means may be means for injecting a flame such as a burner or a torch.

Heat treatment is preferably carried out at a temperature of 300 ℃ to 400 ℃. If the heat treatment temperature is less than 300 ℃, there is a fear that the bonding force with zinc to be made in the subsequent step is lowered, and if the heat treatment temperature is more than 400 ℃, there is a fear that the cut portion of the wire rope.

The heat treatment means is preferably carried out through a burner, torch or the like.

After the heat treatment, the method may further include performing a zinc chloride solution treatment of the portion where the wire rope is inserted (FIG. 12 (g)). Specifically, the zinc chloride treatment is performed simultaneously with the heat treatment, or the zinc chloride treatment is performed immediately after the heat treatment, so that impurities remaining in the wire socket and the wire rope can be easily removed and evaporated, and the zinc melt and Make it easy to join the wire rope.

After the heat treatment, before the zinc melt is added, the wire socket and the wire rope are combined to finish the outer portion through the mud composition to prevent the zinc melt from flowing out (FIG. 12 (h)). Specifically, in the wire socket is provided with a hanger at the top and a through hole toward the top at the bottom, the upper end can be formed to form a dam to surround the insertion portion through the mud, the bottom through hole portion mud Can be finished through.

Before the zinc melt is added, heat treatment of the wire socket may be further performed.

Injecting the zinc melt may be performed such that a portion in which the wire rope is inserted into the wire socket is formed with a convex protrusion (Fig. 12 (i)).

The zinc melt may be melted at a temperature of 1000 ° C to 1200 ° C. Referring to the melting point of zinc at 419.73 ° C., it can be maintained at the above zinc melt temperature range in order to easily remove impurities in zinc.

It is preferable to air-cool at normal temperature after zinc zinc melt injection.

After the zinc melt is added, concave grooves may occur, not completely filled with holes in the wire socket, and the grooves are heat-treated at a temperature of 300 ° C. to 400 ° C. through heating means, and then the zinc melt is reloaded. It can be air cooled at room temperature (Fig. 12 (j)).

The wire rope socket terminated by the above-described method has an effect of stably maintaining the socket coupling even with a strong tensile force compared to the socketing method through the conventional wire lock due to the unique processing method.

In addition, in consideration of the flow on the line has a simple structure that can be adjusted by using a turnbuckle the tensile force of the wire rope has the advantage of ease of use.

In addition, it can be applied to combine the seabed probe, there is an advantage that can maintain the bonding force in the seabed environment.

In addition, the cost of socketing work is inexpensive, and there is an advantage in that the socketing work is possible only with the equipment of a general marine facility without adding special equipment.
