Description

  The present invention relates to an improvement of a long article packaging box used for transporting a long article. In this specification, the long article includes not only a long insulator made of a brittle material such as a large steel tube and a bushing but also an article having a length of several meters such as a long metal structure which is easily bent. It is.

  For example, when a long insulator having a length of 5 m is transported by ship or truck, a long packaging box is used to protect the long article being transported from damage. As shown in FIG. 5, a conventional box for a long article insulator is generally a wooden box having a pine-like wood as a bottom frame 1. A large number of support plates 2 sandwiching the trunk (the valley between the caps) of the long insulator placed horizontally from above and below are arranged inside.

  However, since the long insulator is heavy, the packaging box is also required to have strength. In particular, the bottom frame 1 has a large cross-sectional area in order to avoid deformation, and large wood having a length of 5 m to 6 m or more is required. . However, such large timber is expensive because it is made from an old tree, and the cost of the packaging box increases. In addition, in the case of export, depending on the export destination, a wooden packaging box may be required to be heat-treated to prevent pests such as pine worms, which also increases the cost.

  In addition, when a wooden packing box containing a heavy insulator, which is a heavy object, is lifted by a crane, the entire packing box may be greatly bent into a bow shape. For this reason, the number of support plates 2 sandwiching the body of the long insulator from above and below is increased to disperse the load of the long insulators, and these support plates 2 are manufactured on the spot and fixed with nails. There is a problem that the number of packing operations is increased.

In addition, there are few patent documents regarding the packing of long insulators, and the packaging technique as shown in Patent Documents 1 and 2 is only slightly known. Patent Document 1 relates to a hanging insulator packaging frame, and Patent Document 2 relates to a packaging box for a gas-filled capacitor bushing. Patent Document 2 discloses a similar one to the packaging box shown in FIG.

  SUMMARY OF THE INVENTION To solve the above-mentioned problems of the prior art, the present invention provides a long article packaging box that can eliminate expensive large timber and can reduce the packaging cost by reducing the number of packaging operations. It was made.

  The long article packaging box of the present invention made to solve the above-mentioned problems is a wooden or a top part of a vertically long metal pallet that receives the lower half of the long article placed horizontally on the metal pallet. The resin-made support bodies are erected at appropriate intervals, and the entire upper part of the metal pallet is covered with a lid.

  It is preferable that the wooden or resin support is attached to vertical guides provided on the metal pallet at appropriate intervals, and the wooden or resin support is made of plywood. be able to. Moreover, it is preferable that the support body made from wood or resin is provided with the recessed part corresponding to the shape of a long article.

  Since the long article packaging box of the present invention is constructed by standing up a wooden or resin support for receiving the lower half of the long article on the upper surface of the metal pallet at appropriate intervals, it is expensive as in the past. Large wood is not required, and the contact part with a long article is made of wood or resin, so that even if the long article is a brittle material such as a porcelain long insulator, it is transported without being damaged. be able to. Further, since the entire upper part of the metal pallet is covered with a lid, the long article is protected even if there is a fallen object from above.

  Furthermore, since the metal pallet can have high rigidity by using a steel mold such as an angle, it is difficult to bend even when the packaging box is lifted by a crane. For this reason, the number of supports can be reduced as compared with the conventional wooden box, and in particular, replacement can be facilitated by using a built-in support plate as shown in the embodiment. Costs can be significantly reduced.

Hereinafter, preferred embodiments of the present invention will be described with reference to the drawings.
FIG. 1 is an overall perspective view showing an embodiment of a long article packaging box according to the present invention, FIG. 2 is a perspective view of a state in which the lid is opened, FIG. 3 is an enlarged view of a main part, and FIG. FIG. In this embodiment, the long article W is a long insulator (a porcelain bushing) having a length of about 5.5 m provided with a number of shades.

  In FIGS. 1 and 2, 10 is a metal pallet constituting the bottom surface of the long article packaging box of the present invention, and 11 is a wooden lid covering the entire upper part. The metal pallet 10 is made by welding steel materials such as L-shaped steel, C-shaped steel, and square pipes in a frame shape, and a forklift fork can be inserted by welding an appropriate number of steel shapes (channels) 12 to the bottom surface. It has become. The metal pallet 10 is vertically long, and in this embodiment has a total length of about 6 m and a width of about 1 m. Such a metal pallet 10 is lighter, less likely to bend, and cheaper than a conventional wood bottom pedestal of the same size.

  On the upper surface of the metal pallet 10, vertical guides 13 are erected at appropriate intervals. The vertical guide 13 is a structure in which a total of four L-shaped steels are welded facing the left and right sides of the metal pallet 10 as shown in an enlarged view in FIG. It has become. The interval between the vertical guides 13 is narrow on the base side where the bushing diameter is large and heavy, and is wide on the tip side. However, since the metal pallet 10 has high rigidity, the number of the vertical guides 13 is smaller than that of the wooden box shown in FIG. There is no problem.

  The support plate 14 includes an outer frame portion 15 including both side walls and a bottom plate, and a flat plate portion 16 that receives a lower half portion of the long article W. These are all made of wood or resin, and consideration is given so as not to damage the long article W even if the long article W made of porcelain is supported. In a preferred embodiment, the support plate 14 is made of plywood such as poplar material. Plywood is inexpensive and strong, and has the advantage of satisfying the quarantine standards of the export destination because it is pressed at high temperature in the manufacturing process. The flat plate portion 16 of the support plate 14 is formed with a semicircular concave portion 17 corresponding to the valley shape of the cap of the long article W. The depth is naturally deep on the base side of the bushing and shallow on the tip side.

  The support plate 14 is used by fitting the outer frame portion 15 to the vertical guide 13 of the metal pallet 10. However, the porcelain long article W may be fired in the firing process and may not be fired as designed. For this reason, even if the position of the vertical guide 13 is determined according to the design drawing and welded, the flat plate portion 16 of the support plate 14 may not be accurately positioned in the trough between the caps of the long article W in units of several millimeters. There is. For this reason, the flat plate portion 16 of the support plate 14 is separated from the outer frame portion 15, and the position of the flat plate portion 16 is adjusted on the spot and can be fixed to the outer frame portion 15 from the side by nailing. It is preferable.

  In this way, the support plates 14 are respectively fitted to the vertical guides 13 of the metal pallet 10, and the long article W lifted horizontally by the crane is placed on the support plate 14. At this time, the semicircular concave portion 17 of each support plate 14 is fitted into a trough between the caps of the bushing which is the long article W so as to support the trough. Accordingly, it is possible to prevent the long article W from being displaced in the axial direction during transportation. The long article W is preferably wrapped in advance with a resin sheet or the like.

  In this state, the lower side of the long article W is fitted between the support plates 14, but the upper side remains exposed on the support plate 14. Therefore, it is firmly fixed to the metal pallet 10 with a rubber band or the like, and further covered with a wooden lid 11 to prevent dust during transportation or damage by falling objects from above. Since the wooden lid 11 does not require strength, it can be manufactured from inexpensive wood. If the lid 11 is divided into two in the longitudinal direction as shown in FIG. It is preferable to pack an appropriate filler in the space between the lid 11 and the long article W.

  In the embodiment described above, the long article W is a long insulator (bushing), but a large metal structure that is easily deformed can be similarly packed. Thus, the long article packaging box of the present invention is suitable for safely transporting long insulators and other long articles W, and does not require expensive large-scale wood as in the prior art. In addition, since the metal pallet can have high rigidity, it is difficult to bend even when the packing box is lifted by a crane, and the number of supports can be reduced as compared with the conventional wooden box. As described above, the present invention can greatly reduce the packaging cost.

It is a whole perspective view which shows embodiment of the elongate article packing box of this invention. It is a perspective view in the state where a lid was opened. It is an expansion perspective view of the principal part. It is a perspective view in the state where a long article was packed. It is a whole perspective view of the conventional wooden box.
