Description

  The present invention relates to a container transport packaging used for transporting a vertically-long porcelain insulator having a length of 2.3 m or less. In this specification, the term “insulator” includes not only a solid insulator but also a soot tube and a bushing.

  Cargo ships are mainly used to transport the insulators outside the country and remote areas, and in that case, standard containers such as 20-foot containers and 40-foot containers are usually used. In addition to protecting the insulator from damage during transportation, the insulator was stored in a wooden box that also serves as a platform (pallet) and transported by being loaded inside the container for the convenience of cargo handling work such as a forklift.

  However, due to the fact that the price of timber has risen in recent years and that Japan has been designated as a pine weevil pest-contaminated area, it has become costly for chemical treatment of timber, etc. As for packing equipment, replacement of wooden boxes with steel structure boxes is in progress. For example, Patent Documents 1 and 2 of the applicant of the present application disclose a steel container shipping packaging for a large bushing having a length of 5 to 10 m.

  It is common knowledge that such packaging for container transportation is designed to be as small as possible according to the outer diameter of the object to be transported in order to increase the loading efficiency to the container as much as possible. Conventionally, individual designs have been made in accordance with the size of individual insulators, and the sizes have varied.

  In the case of a large bushing having a length of 5 to 10 m as shown in Patent Documents 1 and 2, it is physically impossible to store a plurality of bushings inside the container, so one bushing is stored. The container transporting packing tool is installed in the center of the container, and a spacer is attached to the inner wall surface of the container by on-site alignment work to prevent a shift during transportation.

  On the other hand, in the case of medium to small insulators with a length of 2.3 m or less, many containers are loaded inside the container. In this case, the container is individually designed according to the size of each insulator. Shipping packaging is stacked inside the container.

However, if a container shipping packaging individually designed according to the size of the insulator is loaded in the container without any gaps, gaps are always generated in the width and depth directions. It was necessary to attach a spacer between them to prevent the shift during transportation, and the work cost was not negligible. Moreover, there are inevitably many kinds of container transport packing tools individually designed according to the size of the insulator, and the production cost and the management cost are also increased. In particular, in the case of medium-sized to small-sized insulators, since the shipment quantity is large, cost reduction has been strongly demanded.

  The present invention solves the above-mentioned conventional problems, and can reduce the work required for on-site adjustment when transporting a vertically-long porcelain insulator having a length of 2.3 m or less in a container, as well as manufacturing costs and management costs. An object of the present invention is to provide an insulator container transporting packing tool that can be transported safely as in the case of conventional products.

  The invention of claim 1 made to solve the above problems is a packing tool for storing and transporting porcelain insulators in a standard container, and has a long side corresponding to the lateral width of the container, In the upper surface of the platform having a short side with a length equal to the depth of the container, a plurality of support bases are installed to support the central part of a plurality of horizontally placed insulators. It is characterized by standing up columns for stacking. In addition, as described in claim 2, it is preferable that the support base is made of a concave steel plate and is arranged in parallel with the long side or the short side inside the upper surface of the platform.

  In addition, as described in claim 3, it is preferable to provide a ceiling frame and a lid frame on the upper surface of the support pillars erected on the outer periphery of the platform, and to form a box shape as a whole. According to the fourth aspect of the present invention, the upper surface pressing tool of the lever can be attached to the lid frame, and the pressing tool for preventing the lever from moving in the longitudinal direction can be attached to the lid frame as of the fifth aspect.

  In addition, as described in claim 6, it is possible to fold the stacking struts erected on the outer periphery of the platform so that the packing tool can be returned in a folded state.

  According to the container transport packing tool of claim 1, the long side of the platform on which a plurality of the insulators are loaded is made to coincide with the horizontal width of the container, and the short side has a length obtained by equally dividing the depth dimension of the container. Can be stored without any gaps inside. For this reason, it becomes possible to omit the fixing work by the field alignment for preventing the shift | offset | difference inside a container like the past. Moreover, since the types of platforms can be reduced, production costs and management costs can also be reduced. In addition, since stacking is possible, the loading efficiency to the container is comparable to the conventional product.

  In addition, since most of the vertically-long porcelain insulators having a length of 2.3 m or less are lightweight with a weight of 400 kg or less, the support base is made of a concave steel plate as in claim 2, Even if it is supported by, it will not cause clogging during transportation. However, in the case of a polymer insulator, since the strength of the shade is weak, such a support method is inappropriate.

  If the whole is made into a box shape as in claim 3, the insulator becomes difficult to be damaged from the outside during transportation. In this case, if the upper surface pressing tool of the lever is attached to the lid frame as in claim 4 or the pressing tool for preventing the movement of the lever in the longitudinal direction is attached to the lid frame as in claim 5, Therefore, it is possible to reliably prevent the insulator from shifting.

  In addition, if the structure of the stacking column is made foldable as in claim 6, the packing device can be returned in a state where the column is folded and not bulky, so that the packaging device for container transportation can be recycled. Cost can be reduced.

Hereinafter, preferred embodiments of the present invention will be described with reference to the drawings.
FIG. 1 is an exploded perspective view showing the first embodiment. This container transport packaging tool is for storing two porcelain insulators W having a length of about 2 m and a cap portion diameter of about 50 cm. The container transport packaging tool of the present invention has a platform 1, a support base 2, and a support column 3 for stacking as essential requirements.

  First, the platform 1 is a rectangular bottom frame made of a steel material, and an appropriate number of scraping materials 4 are provided on the bottom surface so that a cargo handling operation by a forklift can be performed to ensure a height from the floor surface. One of the features of the present invention is that the size of the platform 1 is set so as to correspond to the size of the container. The long side a of the platform 1 is matched with the horizontal width of the container, and the short side b of the platform 1 is It is the length which equally divided the depth dimension of the container.

  The inner diameter of the container is substantially constant internationally, and in the case of a 20-foot container, the width, depth, and height are around 2340 mm, 5920 mm, and 2380 mm, respectively. In the case of a 40-foot container, the depth is twice the above. In this embodiment, a 20-foot container is used, and as shown in FIG. 2, the long side a of the platform 1 is 2310 mm, which is substantially matched with the horizontal width of 2340 mm. The short side b of the platform 1 is 1480 mm obtained by dividing the depth of the container into four equal parts. The reason why the above numbers do not exactly match is that a margin for loading with a forklift is required inside the container, and the claims of the present application must be interpreted to include this marginal error. In this embodiment, the short side b has a length obtained by dividing the depth dimension of the container into four equal parts. However, the short side b may be divided into five equal parts or may be divided into three equal parts.

  If the long side “a” and the short side “b” of the platform 1 are set in this way, the container 1 can be loaded exactly inside the container as shown in FIG. This eliminates the need for fixing work on site.

  A support base 2 is installed inside the upper surface of the platform 1. As shown in FIG. 1, the support table 2 supports the central part of a plurality of insulators W placed horizontally. In FIG. 1, two support tables 2 are provided. As shown in FIG. 3, the support base 2 is formed by welding two left and right L-shaped steel members 6 and a thin steel plate 7 (not shown in FIG. 1) on the cross beam 5 of the platform 1 and supports the central portion of the insulator W. The shape prevents rolling in the lateral direction. The insulator W is placed on the support 2 after the resin cushioning material 12 is placed on the L-shaped steel material 6 and the thin steel plate 7.

  Needless to say, the number of support bases 2 should correspond to the number of insulators W. In the second embodiment shown in FIG. 4, three support bases 2 are provided so as to support three insulators W. Yes. In addition, the support stand 2 can also be divided into two in the longitudinal direction of the insulator W, and is not necessarily provided at the center. In this embodiment, the insulator W is supported in parallel with the long side a of the platform 1, but it can also be supported in parallel with the short side b.

  A stacking column 3 is erected on the outer periphery of the platform. In this embodiment, twelve support columns 3 are erected, and a ceiling frame 8 and a lid frame 9 are provided at the upper ends thereof, and the whole is box-shaped. In this way, if the packaging for container transportation is in the form of a box, the risk of the insulator W being damaged during transportation or cargo handling is reduced as compared with the case of the platform 1 alone. In addition, the support | pillar 3 is given sufficient intensity | strength to endure a vertical load, and it is made for the packaging tool for container transportation to be stacked in multiple stages.

  In this embodiment, a presser 10 that prevents the lever W from moving in the longitudinal direction is provided near the end of the lid frame 9. This has a function of hanging downward toward the lid frame 9 and contacting the end portion or end fitting of the lever W to prevent the lever W from moving in the longitudinal direction. 1 are all welded except for the lid frame 9, but each surface constituting the hexahedron has a bolt connection or insertion structure as shown in FIG. 8, and is easy to disassemble and assemble. It can also be used as a container shipping packaging. With such a structure, it is possible to stack and transport the panels on each side after dismantling at the time of return, thereby reducing the transportation cost.

  The second embodiment shown in FIG. 4 is also an application of the first embodiment described above, but it is possible to load three levers W and a flat plate instead of the presser 10 on the end face. The point which used the shape upper surface pressing tool 11 is different. This upper surface pressing tool 11 is also attached to the lower surface of the lid frame 9 and presses the upper surface of the shade of the insulator W to prevent longitudinal movement by friction.

  The container transport packaging device according to the first and second embodiments described above is used when the insulator maker sends the insulator W to the customer. As shown in FIG. Therefore, it is possible to omit the fixing work by the on-site alignment for preventing the displacement inside the container as in the conventional case. In addition, the platform can be standardized and its types can be reduced, so the production cost and management cost can be reduced. Moreover, since the support | pillar 3 for stacking is provided, stacking is possible inside a container.

  Although the container transport packaging tool of the present invention has such many advantages, when it is in the form of a box as in the above-described embodiment, it is bulky and the return cost is high. For this reason, after taking out the insulator W at the customer, it is not returned and discarded. The third embodiment described below further improves this point.

  FIG. 5 and subsequent figures show the third embodiment. The dimensions of the platform 1 and the support base 2 are the same as those of the above embodiment, but the stacking struts erected on the outer periphery of the platform 1 are shown. The difference is that the column 20 is foldable. The support column 20 is supported by a bracket 21 welded on the platform 1 so as to be foldable by a horizontal shaft 22, and has a function of stably maintaining the upright state shown in FIG. 5 and the folded state shown in FIG. Such a folding structure itself is well known.

  In order to increase the storage efficiency inside the container, the container transportation packing tool of the present invention is usually stacked. Since this support | pillar 20 can maintain an upright state stably, several steps | paragraphs can be piled up like FIG. For this reason, the leg part 23 into which the upper end of the column 20 is fitted is provided on the lower side of the platform 1.

  The container transport packaging tool according to the third embodiment can fold the support column 20 as shown in FIG. 6 after the customer W has lowered the insulator W. For this reason, since it can be stacked and returned in a container, it can be used repeatedly, not disposable. As a result, transportation costs can be reduced and resources can be effectively used. Since other advantages are the same as those of the other embodiments, description thereof is omitted.
