A ship plays a role of moving long-distance by loading large-capacity cargo or personnel, and in order to perform this role, countless devices are installed inside and outside the ship in consideration of the long-term movement time.

The domestic shipbuilding industry has the world's leading design and production technology due to the existence of large shipbuilders that build large ships, and in terms of production technology, the most efficient way to install the above-mentioned innumerable devices A lot of development is going on.

Along with the hull work that constitutes the ship's skeleton, the electric field work of supplying electric power to operate various devices and laying cables for signal transmission constitutes a major axis of ship construction.

In particular, in recent years, the types of ships built in large domestic shipyards are changing from general crude oil carriers or container ships to special ships such as LNG carriers and drillships. Instrumentation is becoming more and more important.

However, despite these changes, the electric field work follows the existing method and its improvement is urgently required. It can be said that the typical method of supplying it by hand is the work method.

In such a conventional operation, not only the problem of efficiency in which a plurality of workers must be arranged, but also the cable is often damaged due to the impact of the cable on the cable tray. Safety accidents involving workers were frequent.

As a part of this improvement, a robot for laying cables or a method for transferring cables using a structure fixed to a cable tray have been developed, but these methods are used when a plurality of cables are installed in one cable tray. There were problems such as mixing or arranging cables even on a cable tray, and installing and removing each structure rather caused additional work.

The jig for cable laying according to a preferred embodiment of the present invention is composed of a support means 100 , a space forming means 200 , a fixing means 300 , and a rolling means 400 as shown in FIG. 1 .

First, look at the cable tray 10 on which the components are installed.

The cable tray 10 may be a generic term for wiring or pipes represented by the cable (C) in the ship to be seated.

In general, the cable tray 10 may be formed to be exposed or buried in the upper portion of the passage formed inside the ship.

The installation of the cable tray 10 is often made before keel laying of the block on the dock where the overall construction of the ship is made, which is a block for the convenience of operation (Turn over) This is because it is easy to work in the state in which the down welding is performed before being installed, the pawl is installed inside, or in the open state before the prior mounting of the block.

The cable tray 10 is perpendicular to the first support 11 and the first support 11 formed in parallel in the longitudinal direction, which is the wiring direction of the cable (C), in order to prevent the cable (C) from falling by being seated on the top. It may be formed of a plurality of second supports 12 .

Due to the shape of the first support 11 and the second support 12 , the cable tray 10 has a ladder-like shape as a whole, and is perpendicular to both the first support 11 and the second support 12 . It can be fixed spaced apart from the surface of the ship by the third support (13) is formed.

To summarize and explain, when the cable (C) is laid in the cable tray (10), the cable (C) is not separated to the left and right by the first support (11), does not fall by the second support (12), 3 may be spaced apart from the surface of the ship by the support (13).

The size of the cable tray 10 can be formed in various ways, and the thickness or material of the first support 11 to the third support 13 varies according to the number and weight of cables C that can be installed. can be formed.

Next, look at the support means (100).

The support means 100 has both ends fixed to the cable tray 10 , in detail, it is formed between the first supports 11 of the cable tray 10 and can be formed parallel to the second support 12 . have.

The support means 100 has both ends fixed between the first supports 11 of the cable tray 10, and spaced apart from the second support 12, thereby impacting the cable C to be installed on the cable tray 10. You can prevent this from happening.

That is, the support means 100 may serve to support the cable C so that it can move in a state spaced apart from the cable tray 10 .

The support means 100 may be made of any material, but preferably a wire made of stainless steel.

As described above, since the cable tray 10 can be formed in various sizes, according to the need to adjust the length of the support means 100 in various ways, a shape such as a wire is adopted, but corrosion resistance and abrasion resistance are taken into consideration. Thus, it may be preferable to be made of stainless steel.

An elastic means 500 may be further provided at one or both ends of the support means 100 .

Since the support means 100 should be installed on the cable tray 10 of various sizes as described above, it can be flexibly installed in various sizes due to the provision of the elastic means 500 and can be easily attached and detached using the hook 530 . do.

Preferably, the support means 100 is formed to be longer than the width of the general cable tray 10 so that the first support 11 of the cable tray 10 is wound at least once more as the load is applied to the rolling means 400 . The portion wound on the support means 100 is further tightened by the first support 11 so that it is fixed by the elastic means 500 formed at both ends, thereby forming a strong tension in the support means 100 so that the cable (C) is connected to the cable. It may serve to maintain so as not to contact the tray 10 .

The elastic means 500 may be formed by coupling the elastic band 510 and the hook 530 .

One end of the elastic band 510 may be coupled to the support means 100 , and may serve to provide tension due to elasticity to the support means 100 , which is made of a stainless steel wire and has no elastic force.

A hook 530 may be coupled to the other end of the elastic band 510 , and the support means 100 is directly installed on the cable tray 10 , and the hook 530 is used to facilitate installation and separation thereof. can be hired

In detail, hooks 530 are formed at both ends of the support means 100 so that when installed on the cable tray 10, one end of the support means 100, which is a wire, is connected to the first support 11 of the cable tray 10. It may be wound on and fixed to the support means 100 or the elastic band 510 using a hook 530 .

The hook 530 may be of any shape, but when installing the support means 100 on the cable tray 10 , it is an elastic hook so that an elastic force can be added to the hook 530 for easy attachment and detachment of the operation. It may be desirable to do so.

Additionally, between the support means 100 and the elastic means 500, that is, the support means 100 and the elastic band 510 is formed on the side to which the hook coupling hole 550 is coupled to the hook 530 is coupled. It may also be possible to facilitate it.

Next, look at the space forming means 200 .

The space forming means 200 may be installed in the support means 100 , and may serve to form a closed space in which the cable C can move through coupling with the support means 100 .

Due to the provision of the space forming means 200, the space in which the cable C can move is limited, so that stable work may be possible.

In addition, the space forming means 200 may serve to limit the area in which the rolling means 400 to be described later should be provided inside the support means 100 .

The space forming means 200 may be in the form of a wire, and may be formed of stainless steel and made of the same material as the above-described support means 100 .

Both ends of the space forming means 200 are coupled to the support means 100 , and may be movable on the support means 100 .

In detail, both ends of the space forming means 200 are coupled to the support means 100 which is a wire, but the support means 100 is not fixed to the support means 100 by being defective using the ring coupler 210 . ) as a guide, both ends of the space forming means 200 can be moved freely.

In addition, the space forming means 200 is fixed to the upper part using an additional binding material such as a string or a cable tie as shown in FIG. The load and friction force can be distributed by widening the contact area of the

The free movement of both ends of the space forming means 200 expands the scope of application of the present invention by adjusting the positions of both ends according to the size of the cable (C) to be installed so that the size of the space can be variously provided. effect can be obtained.

Additionally, the ring coupling hole 210 installed at both ends of the space forming means 200 may also be possible to be fixed to the support means 100 by itself, which in turn includes the fixing means 300 to be described later and It may be formed integrally.

Next, look at the fixing means 300 .

The fixing means 300 may serve to prevent both ends of the space forming means 200 from being separated from the center.

When the side on which the cable (C) is moved relative to the support means 100 is referred to as the inner side and the side fixed to the cable tray 10 is referred to as the outer side, the fixing means 300 are located outside both ends of the space forming means 200 . can be provided.

The fixing means 300 is installed on the support means 100 and can be moved and fixed, so that when the space forming means 200 moves on the support means 100 , it can be moved accordingly, and after the movement is completed By being fixed to the support means 100, it is possible to prevent the space forming means 200 from being separated to the outside.

The fixing means 300 may have various shapes, but may include a fixing nut 310 installed on the support means 100 and a fixing bolt 330 coupled to the side of the fixing nut 310 .

Specifically, the fixing nut 310 is installed so that the supporting means 100 passes through the center through hole, and the fixing bolt 330 is formed to be perpendicular to the side surface of the fixing nut 310, so that the fixing bolt 330 is By pressing the support means 100, the fixing means 300 may be fixed.

Preferably, the fixing bolt 330 may be configured in the form of a butterfly bolt to facilitate fixing and releasing by an operator.

As described above, the fixing means 300 is generally formed separately from the space forming means 200 , but the fixing means 300 is coupled to a part of the space forming means 200 , in particular the ring coupler 210 . A form in which there is may also be possible.

Next, look at the rolling means 400.

The rolling means 400 is coupled to the support means 100 , and may be installed inside both ends of the space forming means 200 .

The rolling means 400 supports the lower portion of the cable (C) passing through the space forming means 200, but allows easy movement by the clouds, thereby obtaining the effect of obtaining easiness of work.

The rolling means 400 may have any form of rotating the support means 100 as an axis, but is preferably formed of a rolling bearing having a through hole in the center, and the support means 100 passes through the through hole. It may be in the form that is formed.

The rolling bearing is not limited to the type such as a needle bearing or a ball bearing, but it may be preferable to use the one having the smallest volume in order to form the space inside the space forming means 200 as wide as possible.

A plurality of rolling means 400 may be installed inside the space forming means 200 , and a plurality of rolling means 400 may be installed so as to be densely formed in the entire inner space of the supporting means 100 formed by the space forming means 200 . can

Additionally, it may be possible to form the plurality of rolling means 400 so that there is no space spaced apart inside the space forming means 200 by magnetically coupling the side surfaces to each other.

Using the above-described components, look at the method of laying the cable (C) using the present invention.

In general, the cable tray 10 is installed during the ship hull work by the third support 13, and the cable C is installed in the space formed by the first support 11 and the second support 12. .

Install the cable installation jig of the present invention before the installation of the cable (C).

The present inventor's jig for cable installation can be installed in the cable tray 10 by fixing both ends of the supporting means 100 to the first supports 11 of the cable tray 10, respectively. Accordingly, a plurality of parallel but spaced apart second support 12 may be installed.

After the one side of the support means 100 is wound around the first support 11 , the hook 530 of the elastic means 500 is coupled to the hook coupler 550 .

At this time, by forming the support means 100 to be sufficiently long, it is possible to make a strong coupling by making it overlappingly wound on the first support 11 .

After pulling the other side of the supporting unit 100 so that the supporting unit 100 does not come into contact with the second supporting unit 12 of the cable tray 10, it is wound around the first supporting unit 11 and then the other side of the hook 530 is connected to the other side. It is coupled to the hook coupler 550 .

Through the above-described process, the support means 100 may be coupled between the first supports 11 , but spaced apart from the second support 12 may be maintained.

Additionally, by making the support means 100 longer than twice the length of the second support 12 , it may be possible to install more firmly.

In detail, as shown in FIG. 6, one side of the support means 100 is wound on the first support 11 on the same side, and then wound on the first support 11 on the other side and fixed to the hook 530 on the other side. form may be possible.

In the case of this installation type, a plurality of supporting means 100 may be cross-installed on the upper and lower portions of the first support 11 so as to be parallel to the second support 12 .

In order to move the position of the space forming means 200 to the position where the cable C is to be installed, both ends of the fixing means 300 and the space forming means 200 can be moved by releasing the butterfly bolt of the fixing means 300 . let it be

At this time, the movement of the space forming means 200 also applies the movement of the rolling means 400 inside the space forming means 200, and when the location of the space forming means 200 is determined, the fixing means 300 is locked. do.

When the fixing means 300 is locked, the rolling means 400 are densely formed inside the space forming means 200 so that there is no spaced apart space, so that when the cable C is installed, the cable C is connected to the support means 100 and Avoid contact.

Additionally, by fixing the upper part of the space forming means 200 to the upper structure using other binding materials such as a string or cable tie, as shown in FIG. 5 , the sagging of the space forming means 200 is prevented, and the rolling means 400 ), the load and friction force can be distributed by widening the contact area.
