Abstract

PROBLEM TO BE SOLVED: To provide a wing body packing method and a wing body packing set, which enable a wing body to be rapidly and inexpensively packed with proper workability.SOLUTION: In a wing body packing method of the present invention, a front edge of a wing body is detachably covered with a recess of a front edge cover member; a back edge of the wing body is detachably covered with a recess of a back edge cover member; and a tip of the wing body and wing surfaces on both sides are detachably covered with the whole cover member. This makes it unnecessary to preform urethane assuming a dedicated special shape corresponding to each of front, rear, right, left, upper and lower shapes of the wing body, so as to elastically hold the wing body, and also makes it unnecessary to manually pack the wing bodies with a bubble cushioning material on a one-by-one basis.

Description

  The present invention relates to a blade body packing method and a blade body packing set for packing a blade body used as a moving blade or a stationary blade of a compressor or a gas turbine.

  A blade body used as a moving blade or a stationary blade of a compressor, a gas turbine, or the like uses a dedicated blade body container for its transportation. The wing body accommodation container has, for example, a plurality of cuboid-like wing body accommodation spaces corresponding to the wing bodies, and the wing bodies are individually accommodated in these wing body accommodation spaces. These wing body accommodation spaces are generally partitioned by wing body partition walls.

  However, when the wing body is simply accommodated in the wing body accommodating space, a gap is generated between the wing body and the wing body partition. When the wing body container is transferred in such a state, the wing body may collide with the wing body partition wall due to vibration or the like, and may be damaged.

  In view of this, there has been a proposal for elastically holding the wing body by arranging urethane, which is a plurality of elastic bodies, in the gap between the wing body and the wing body partition (see, for example, Patent Document 1).

  However, since the front edge cover member 110 and the rear edge cover member 120 detachably attached to the front edge 230 and the rear edge 240 of the wing body 200 are fastened by the cover fastening member 130, the substantially vertical front edge 230 and rear edge 240 are fixed. The cover fastening member 130 can prevent the front edge cover member 110 and the rear edge cover member 120 attached to the cover from falling off.

  In particular, since the cover fastening member 130 is elastically stretchable, the front edge cover member 110 and the rear edge cover member 120 can be easily fastened to the front edge 230 and the rear edge 240. Moreover, the cover fastening member 130 is formed in an annular shape, and for example, a commercially available rubber band can be used.

  Then, when such a cover fastening member 130 is manually expanded, if it is disposed and released from above around the wing body 200 on which the front edge cover member 110 and the rear edge cover member 120 are mounted, an annular shape is obtained. The cover fastening member 130 contracts elastically. For this reason, the front edge cover member 110 and the rear edge cover member 120 can be easily and elastically fixed to the wing body 200 by the cover fastening member 130.

  Furthermore, in the wing body packing method using the wing body packing set 100 of the present embodiment, a plurality of wing bodies 200 each covered by the front edge cover member 110, the rear edge cover member 120, and the entire cover member 140 are provided. The blade housing members 150 are individually housed in a plurality of cuboid blade housing spaces 156 defined by blade body partition walls 154 and 155. The wing body 200 is restricted from moving in the front-rear direction in the wing body housing space 156 by the front edge cover member 110 and the rear edge cover member 120. Further, the movement in the left-right direction within the wing body accommodating space 156 is restricted by the reaction force of the entire cover member 140 that has warped. For this reason, the plurality of wing bodies 200 can be accommodated and transferred in one wing body accommodating member 150 without causing damage due to vibration or the like.

  The present invention is not limited to the present embodiment, and various modifications are allowed without departing from the scope of the present invention. For example, in the above embodiment, a moving blade of a compressor is exemplified as the blade body. However, such a blade body may be a compressor stationary blade, a gas turbine moving blade, a gas turbine stationary blade, or the like.

  Further, in the above embodiment, the wing body housing member 150 of the wing body packaging set 100 includes the housing member base 151 and the housing member cover 152, and a plurality of upper spaces of the flat wing body holding bottom plate 153 of the housing member base 151 are provided. The wing body partitioning spaces 154 and 155 are divided into a plurality of rectangular parallelepiped wing body housing spaces 156 for individually housing the wing bodies 200, and the entire body is covered with the housing member cover 152.

  However, as in the wing body packing set 300 illustrated in FIG. 7, the wing body housing member 310 includes the housing member box 311 and the housing member cover 312, and the interior space of the housing member box 311 having the upper surface opening includes a plurality of wing bodies. The wing body housing spaces 156 each containing the body 200 may be partitioned by wing body partition walls 154 and 155, and the upper surface opening may be sealed with a flat plate-shaped housing member cover 312.

  Furthermore, the cover fastening member 130 is illustrated as being made of an elastic rubber ring that is elastically stretchable. However, such a cover fastening member may comprise, for example, a binding band that can be adjusted tightly and loosely (not shown).

  In this case, for example, the front edge cover member 110 and the rear edge can be obtained simply by surrounding and binding the wing body 200 to which the front edge cover member 110 and the rear edge cover member 120 are mounted with a cover fastening member made of a binding band. The cover member 120 can be fixed to the wing body 200. For this reason, the front edge cover member 110 and the rear edge cover member 120 can be reliably fixed to the wing body 200 simply and quickly.

  In the above embodiment, after the front edge cover member 110 and the rear edge cover member 120 of the wing body 200 are fastened by the cover fastening member 130, the tip 220, the positive pressure surface 250, and the negative pressure surface 260 of the wing body 200 are fixed. The cover with the whole cover member 140 is exemplified. However, after covering the wing body 200 with the front edge cover member 110, the rear edge cover member 120, and the whole cover member 140, the whole body may be fastened with the cover fastening member 130.

  Moreover, in the said form, although the leading edge cover member 110 and the trailing edge cover member 120 showed what has substantially the same length as the blade height H in the wing body 200, the length is 30% or more of the blade height H. If it has, it is expected that the effect of shock relaxation can be exhibited considerably.

  Needless to say, the above-described embodiment and a plurality of modifications can be combined within a range in which the contents do not conflict with each other. Further, in the above-described embodiments and modifications, the structure of each part has been specifically described, but the structure and the like can be changed in various ways within a range that satisfies the present invention.
