BRIEF DESCRIPTION OF THE DRAWINGS The advantages and features of the present invention and the manner of achieving it will become apparent with reference to the embodiments described in detail below with reference to the accompanying drawings.

The present invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art. To fully disclose the scope of the invention to those skilled in the art, and the invention is only defined by the scope of the claims.

In the following description, well-known functions or constructions are not described in detail since they would obscure the invention in unnecessary detail.

1 and 2, the jig 100 for installing a crane according to the present invention includes a horizontal frame 110, a first vertical frame 120, and a second vertical frame 130.

First, the horizontal frame 110 is horizontally installed at a temporary assembling position, and functions as a base to which a pinned leg 10 and a gantry crane 20 can be installed.

A plurality of supports 111 connected to the first vertical frame 120 and the second vertical frame 130 may be further provided on both sides of the upper end of the horizontal frame 110.

The lower ends of the supporting frames 111 are coupled to the upper ends of the horizontal frames, and the other ends of the supporting frames 111 are connected to corresponding surfaces of the first vertical frame 120 and the second vertical frame 130, Lt; / RTI >

That is, the first vertical frame 120 and the second vertical frame 130 can be firmly installed around the horizontal frame 110 by the supports 111.

The first vertical frame 120 is vertically installed on one upper end of the horizontal frame 110 and the legs 10 are vertically coupled to one side of the first vertical frame 120.

The first vertical frame 120 supports the leg 10 coupled to the lower end of the gantry crane vertically.

To this end, the first vertical frame 120 and the legs 10 may be provided with fastening portions for mutual coupling.

The second vertical frame 130 is vertically installed at the other upper end of the horizontal frame 110 opposite to the first vertical frame 120.

The other end of the gantry crane 20 is temporarily coupled to the upper end of the second vertical frame 130.

Here, the second vertical frame 130 may further include a plurality of connection portions 131 forming a multi-layered layer along the vertical direction.

The connecting portions 131 may be respectively coupled to the upper and lower longitudinal directions of the legs 10 at different heights.

The horizontal frame 110, the first vertical frame 120, and the second vertical frame 130 may be combined into a frame using a plurality of beams.

The gantry crane 20 may be provided with first and second engaging portions for engaging the legs 10 and the jig 100 at both lower ends thereof.

The gantry crane 20 is provided with various driving devices (driving motors, etc.) for traction.

3 and 4, the jig mounting step S100, the leg mounting step S200, the assembling step S300, the separating step S400, And a field installation step S500.

First, in the step of installing the jig S100, the assembly jig 100 is installed at a temporary assembling position.

At this time, the horizontal frame 110 of the assembly jig 100 is positioned on the ground, and the first vertical frame 120 and the second vertical frame 130 coupled to both ends of the horizontal frame 110 are positioned at a predetermined height .

Here, before the jig installing step S100, a carrying step for moving and positioning the assembly jig 100, the leg 10, and the gantry crane 20 to a temporary assembling position may be further included using the transportation equipment .

Next, the leg installing step S200 temporarily links the leg 10 to one side of the installed assembly jig 100.

That is, the legs 10 are vertically installed at the upper end of the first vertical frame 120 located at one side of the assembly jig 100.

As described above, since the legs are coupled to the first vertical frame of the pre-installed jig in the leg installing step (S200), the gantry crane described later can be stably coupled to the legs.

Next, in the assembly step S300, the lower end of one side of the gantry crane 20 is engaged with the upper end of the leg 10, and the other lower end of the gantry crane 20 is temporarily attached to the upper end of the assembly jig 100 Lt; / RTI >

At this time, in the assembly step S300, the assembly jig 100, the leg 10, and the gantry crane 20 are integrally joined.

The assembling step S300 is a pre-assembling process for carrying the gantry cranes and the legs to a single body in a field installation step to be described later.

That is, the legs 10 and the gantry cranes 20 can be stably assembled using the assembly jig, thereby improving the workability and preventing the equipment damage, and reducing the risk of safety accidents.

Next, in the separation step S400, the lower end of the gantry crane 20 is separated from the upper end of the assembly jig 100, and the legs 10 and the assembly jig 100 are separated.

Finally, the field installation step S500 carries the integrated gantry cranes 20 and the leg together to complete the assembly at the transfer rail installation position.

That is, since the gantry cranes 20 and the legs 10 are integrated with each other in the extended installation step (S500), they can be installed at one time.

As a result, in the pre-assembly process, the legs and the gantry cranes are assembled using the assembly jig, and then the integrated legs 10 and the gantry cranes 20 are transported and installed in the field, Damage can be prevented.

Further, the legs 10 and the gantry cranes 20 can be joined to each other using the assembly jig 100, so that the risk of a safety accident can be reduced.

Although the present invention has been described with respect to specific embodiments for a crane installation jig and a crane installation method using the same, it is apparent that various modifications may be made without departing from the scope of the present invention.

Therefore, the scope of the present invention should not be limited to the above-described embodiments, but should be determined by the scope of the appended claims and equivalents thereof.

It is to be understood that the foregoing embodiments are illustrative and not restrictive in all respects and that the scope of the present invention is indicated by the appended claims rather than the foregoing description, It is intended that all changes and modifications derived from the equivalent concept be included within the scope of the present invention.
