Description

Jig structure [

The present invention relates to a jig structure.

In the manufacture of ships, it is common practice to manufacture blocks or modules individually and then use a method of joining the respective blocks or modules together. Here, the module may be a specific part of the ship or a unit having a specific function.

In the process of combining these modules, a method of transferring from the ground to another using a crane can be used. Among ships, the drill ship knuckle boom is relatively heavy in weight compared to other modules. When such a knuckle boom is to be fed, a plurality of lugs are welded to the upper side of the knuckle boom. Then, wire the lift wire to the lug.

Here, since the lug is discarded after the transfer operation is completed, there is a problem that it can not be reused. Also, during the welding of the lugs to the knuckle boom, they must be formed avoiding the existing equipment and equipment installation location. Therefore, the force generated by the tension of the wire during the lifting process can not be efficiently distributed to the plurality of lugs, so that the force can be concentrated on the specific lug. As a result, there is a problem that deformation occurs in a specific portion of the knuckle boom where the lug is deformed or the lug is welded.

One embodiment of the present invention is intended to provide a jig structure that not only can be reused, but also allows the tension of the wire to be efficiently dispersed.

A jig structure according to one aspect of the present invention is a jig structure used for conveying a knuckle boom by a crane, comprising: a body member formed to correspond to an upper surface of the knuckle boom; a body member penetrating a part of the body member, And at least one fixing member formed on the upper side of the body member and having a first hole to which the wire of the lift is coupled.

At this time, the body member includes a frame portion formed of a closed curve of a quadrangle, a support portion connecting edges facing each other in the frame, and a frame portion formed to surround an outer side of each corner of the frame portion, And a second hole formed in the second hole.

At this time, the second holes may be formed at a predetermined interval along the edge of the detachable portion.

At this time, the fixing member is composed of four, and each of the four fixing members may be located at the same distance from the center of the frame portion, adjacent to the edge of the frame portion.

In the case of transporting the knuckle boom to the jig structure according to an embodiment of the present invention, the body member can be brought into close contact with the knuckle boom, fastened with the fastening member, and then the wire can be transferred to the fastening member. Accordingly, since the lug welding process is not performed, the working time can be saved by the welding time.

After the transfer operation of the knuckle boom is completed, the fastening member is released to separate the body member from the knuckle boom, and the knuckle boom can be reused when the transfer is required. Therefore, unlike the prior art, there is no need to weld the lug to the knuckle boom and dispose of it. In addition, since the jig structure according to one embodiment of the present invention can be reused many times, the cost due to lug consumption can be reduced.

Also, when a part is referred to as "including " an element, it does not exclude other elements unless specifically stated otherwise.

Before explaining the core structure of the jig structure according to the present invention, the overall structure of the jig structure according to the present invention will be schematically described.

FIG. 1 is a view showing a state where a knuckle boom is transferred to a crane using a jig structure according to an embodiment of the present invention, and FIG. 2 is a perspective view showing a jig structure according to an embodiment of the present invention.

1 and 2, a jig structure 100 according to an embodiment of the present invention is a jig structure 100 used for conveying a knuckle boom 20 by a crane. The jig structure 100 includes a body member 110, A member 120, and a fixing member 130.

Here, the knuckle boom 20 is a cylindrical member. In a general ship, a crane is installed to move a heavy object, and the knuckle boom 20 is installed to use a function such as a crane in a drill ship.

The body member 110 is formed to correspond to the upper surface of the knuckle boom 20. The size of the body member 110 may be similar to the size of the upper side of the knuckle boom 20. When the jig structure 100 according to one embodiment of the present invention is coupled to the knuckle boom 20, the lower side of the body member 110 is brought into close contact with the upper surface of the knuckle boom 20, The knuckle boom 20 can be transported in a stable manner. The detailed structure of the body member 110 for this purpose will be described later.

The fastening member 120 is formed to be coupled to the knuckle boom 20 through a portion of the body member 110. The fastening member 120 allows the body member 110 to be detachably attached to the knuckle boom 20. The fastening member 120 for this purpose may be, for example, a bolt. The bolt passes through the body member 110 and is coupled to the knuckle boom 20. Here, the fastening member 120 is not limited to being a bolt, and any member may be used as long as the body member 110 can be detached from the knuckle boom 20.

The fixing member 130 is formed on the upper side of the body member 110. The fixing member 130 has a first hole 131 formed therein. The wire 11 of the crane 10 is coupled to the first hole 131.

Meanwhile, the detailed structure of the body member 110 may include a frame part 111, a support part 112, and a detachable part 113, for example.

The frame part 111 is formed of a closed curve of a quadrangle. For example, the frame portion 111 may be one in which the four steel beams are sequentially connected at their ends. The steel beam constituting the frame portion 111 may be, for example, an H-shaped beam. However, the present invention is not limited thereto.

The supports 112 connect the opposing edges in the frame. The supporting portion 112 connects two pairs of opposite edges among the four corners of the rectangular frame portion 111. [ The support 112 for this purpose may be made of two steel beams. The steel beam constituting the support portion 112 may be, for example, an H-shaped beam. The supporting portion 112 may be integrally formed with the frame portion 111. The supporting part 112 may be made of the same material as the frame part 111, but is not limited thereto. The support portion 112 can keep the frame portion 111 in an initial shape without being deformed by an external force.

The detachable portion 113 is formed so as to surround the outer sides of the respective corners of the frame portion 111. A second hole 114 is formed in the detachable portion 113. The fastening member 120 passes through the second hole 114 from the upper side to the lower side. That is, when the frame portion 111 is formed in a square shape, the detachable portion 113 can be formed every 90 degrees with respect to the center of the frame portion 111. [

The shape of the detachable portion 113 will be described in more detail. The detachable portion 113 may have an opening that opens laterally. A plurality of barrier ribs 115 may be formed in the openings to divide the openings into a plurality of unit spaces 116. Here, the second holes 114 may be formed on the respective bottom surfaces of the unit spaces 116.

The mechanical strength of the detachable portion 113 can be improved by such a partition wall 115. Thus, even if an external force is generated in the detachable portion 113, the detachable portion 113 may not be deformed.

The second holes 114 may be formed at a predetermined interval along the edge of the detachable portion 113. With this structure, the coupling force between the body member 110 and the knuckle boom 20 can be improved. This makes it possible to more stably maintain the state where the knuckle boom 20 is engaged with the jig structure 100 in a state where the jig structure 100 according to one embodiment of the present invention is coupled to the knuckle boom 20.

Meanwhile, as shown in FIG. 3, in the jig structure 100 according to one embodiment of the present invention, four fixing members 130 may be formed. Each of the four fixing members 130 may be located at the same distance from the center of the frame portion 111, adjacent to the edge of the frame portion 111. [

With this structure, since uniform tension can be applied to the plurality of wires 11 of the crane 10, the tensile force is efficiently dispersed in the plurality of fixing members 130, and the force is concentrated on any one of the fixing members 130 Can be prevented. Accordingly, it is possible to prevent the jig structure 100 or the knuckle boom 20 according to one embodiment of the present invention from being deformed.

Conventionally, the lug was welded to the knuckle boom 20, and then the wire 11 was coupled to the lug and transferred. However, when the knuckle boom 20 is transferred to the jig structure 100 according to an embodiment of the present invention having the above structure, the body member 110 is brought into close contact with the knuckle boom 20, The wire 11 can be coupled to the fixing member 130 and transported. As a result, it is not necessary to carry out the process of welding the lug to the knuckle boom, so that the working time can be saved by the welding time.

In the jig structure 100 according to one embodiment of the present invention, after the transfer operation of the knuckle boom 20 is completed, the fastening member 120 is released to separate the body member 110 from the knuckle boom 20 And the knuckle boom 20 can be reused in the case where transport is required. Therefore, unlike the prior art, there is no need to weld the lug to the knuckle boom 20 and dispose of it. In addition, since the jig structure 100 according to one embodiment of the present invention can be reused many times, the cost of lug consumption can be reduced.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, the drawings and description are to be regarded as illustrative in nature and not restrictive. And is not used to limit the scope of the present invention described in the claims. Therefore, those skilled in the art will appreciate that various modifications and equivalent embodiments are possible without departing from the scope of the present invention. Therefore, the true scope of technical protection of this invention should be determined by the technical idea of the appended utility model registration claim scope.
