The lower ring 120 is rotatably supported by a plurality of roller fixing pins 141 And a lower roller installation groove (115) for installing the lower roller is formed on the lower roller installation groove (115).

Generally, the gas turbine has a structure in which a top hat (not shown) provided with a combustion nozzle, as disclosed in "a method of separating a combustor of a combustor and a gas turbine, and a mounting method (Korean Patent Registration No. 10-1213525) " (Top Hat).

In this case, it is often necessary to separate the top hat for maintenance and maintenance / inspection. However, the top hats are generally mounted in a plurality of rktm turbines, and the respective installation positions are also different.

Therefore, in order to separate the top hat by lifting equipment, the position of each top hat is different. Therefore, lifting equipment capable of moving the center of the lift to match the center of the lifting center of the lifting equipment and the top hat of the gas turbine Since it is necessary to frequently move the center of the lifting, it is troublesome to work, and there is a restriction on the required equipment and a lot of work space.

Patent Document 1: Korean Patent No. 10-1213525

The present invention solves the above problems of the conventional equipment, so that even when the lifting center of the lifting equipment and the center of the top hat of the gas turbine do not coincide precisely, the top hat can be freely moved to the center axis It is possible to avoid the restriction on the installation and operation position of the lifting equipment as well as the gas turbine top hat which can be easily attached to and detached from the top hat, And to provide a rotary coupling structure for lifting.

In order to achieve the above object, the present invention provides a structure for fastening a turbine top hat for lifting a gas turbine top hat, the structure being coupled to and joined to the gas turbine top hat, The upper ring 110 includes a top ring 110 and a bottom ring 120 and a top and bottom fastening means 130 coupling the top ring 110 and the bottom ring 120 to each other, And a plurality of roller installation slots 115 in which a plurality of binding rotation rollers 140 are installed via roller fixing pins 141 are formed in the lower ring 120. The binding rotation rollers 140 are fixed to the roller fixing pins 141 A plurality of lower roller mounting grooves 115 are formed through the lower roller mounting grooves 115.

The upper ring 110 is formed with an upper binding portion 111 having upper binding holes 112 formed at both ends thereof,

The lower ring 120 is formed with a lower coupling part 121 having lower coupling bolt holes 122 at both ends thereof,

The upper and lower fastening means 130 is composed of a fastening bolt that passes through the upper fastening hole 112 and is coupled to the lower fastening bolt hole 122.

In addition, at least one lifting attachment part 150 provided on the upper ring 110 and having an eye bolt installation hole 151 to which the lifting eye bolt can be coupled; And further comprising:

According to the present invention, even when the lifting center of the lifting equipment and the center of the top hat of the gas turbine do not exactly coincide with each other, it is possible to freely adjust the center of the top hat while rotating the top hat against the central axis , It is possible to avoid the restriction on the installation or operation position of the lifting equipment, and it is possible to easily attach and detach it to the top hat, thereby eliminating the troublesome operation of joining the chain block and the like.

1 is a schematic view showing the structure of a gas turbine top hat according to one embodiment of the present invention;
2 is a front view showing a configuration of a rotary coupling structure for lifting a gas turbine top hat according to one embodiment of the present invention;
3 is a perspective view showing a configuration of a rotary coupling structure for lifting a gas turbine top hat according to one embodiment of the present invention;
4 is a front view showing the state of use of the rotary coupling structure for lifting the gas turbine top hat according to one embodiment of the present invention;

Hereinafter, a rotary coupling structure for lifting a gas turbine top hat according to an embodiment of the present invention will be described.

As shown in FIG. 2, the structure for fastening a gas turbine top hat for lifting a gas turbine top hat includes a structure that is coupled to and joined to the gas turbine top hat, An upper ring 110 and a lower ring 120 each having a semicircular shape and upper and lower coupling means 130 coupling the upper ring 110 and the lower ring 120 to each other.

In this case, the upper ring 110 is rotated by a plurality of (not shown) through the roller fixing pins 141, so that the turbine top hatch 10 can freely rotate as shown in FIG. 4 in the lifting process. And a lower roller installation groove 115 in which a plurality of binding rotation rollers 140 are installed via roller fixing pins 141 is formed in the lower ring 120 . Accordingly, the turbine top hat 10 can be freely rotated while being supported by a plurality of the binding rotation rollers 140.

In this case, the configuration in which the binding rotation roller 140 is installed via the roller fixing pin 141 makes it possible to replace the binding rotation roller 140 as necessary, if necessary.

Although the upper and lower fastening means 130 for coupling the upper ring 110 and the lower ring 120 to each other can be used in various embodiments, a tool such as a wrench, which is widely used in a work process, The upper ring 110 is formed with an upper binding portion 111 having upper binding holes 112 at both ends thereof as shown in FIGS. 2 and 3 And the lower ring 120 is formed with a lower coupling part 121 having lower coupling bolt holes 122 at both ends thereof and the upper coupling device 130 is connected to the upper coupling hole 121 112), and is fastened to the lower fastening bolt hole (122).

4, at least one ring is installed on the upper ring 110 so that the lifting eye bolt 30 can be coupled to the upper ring 110, And a lifting gear engagement portion 150 in which a ball 151 is formed.

Hereinafter, the operation of the rotary coupling structure for lifting the gas turbine top hat according to one embodiment of the present invention will be described.

The upper ring 110 and the lower ring 120 are installed in the top hat 10 in a state where the upper ring 110 and the lower ring 120 are separated from each other and then the upper ring 110 and the lower ring 120 are connected to each other using the upper and lower fastening means 130 Thereby coupling the upper ring 110 and the lower ring 120 to the top hat 10.

In this case, the top hat 10 is firmly supported by the coupled upper ring 110 and the lower ring 120, but is supported and coupled in a rotatable state as shown in FIG.

Therefore, even when the lifting center is deviated to some extent with respect to the top hat 10, the top hat 10 can be rotated and the lifting center or the fastening position can be adjusted so as to lift or join.

On the other hand, as shown in FIG. 4, by providing a plurality of pendant fitting portions 150 (generally, it is preferable that the pendant fitting portions 150 are provided so as to have an angular interval of about 45 degrees with respect to the central axis) It is possible to effectively lift it even when the position of the side is slightly out of the side. In other words, while the fastening / installation positions of the top hat 10 (for example, corresponding positions and angles between the fastening holes 22 corresponding to the top hat fastening holes 12 in Fig. 1) This is possible.

It will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention as defined by the appended claims.
