Description

  The present invention relates to a transport protection material and a lifting method for protecting a transported object during transport of the transported object.

  As disclosed in Japanese Patent Application Laid-Open No. 2002-348088, several tools for hanging a cylindrical object with a crane have been proposed. The cylindrical object carrier described here is capable of adjusting the diameter of the ring-shaped main body, and the cylindrical object carrier is mounted on a drum can so that the cylindrical object carrier can be removed from the ring-shaped main body. A pair of flanges projecting outward is hung by hanging a fork of a forklift or a wire of a crane. In the case of a drum can, there is a burr portion on the outer periphery of the upper lid, and the drum can be transported without falling off by hanging the ring-shaped main body of the cylindrical object transporter on the burr portion. In other words, it cannot be used in the case of a cylindrical object having no burr portion. The object to be transported must be cylindrical and cannot be used for anything other than cylindrical.

  FIG. 6 shows an apparatus having a tank made of polyethylene and FRP, which has a conventional frame for crane suspension. Since the tank installed in a vertically long shape does not have a burr like a drum can, the cylindrical object carrier described in JP-A-2002-348088 cannot be used. In FIG. 6, frame members 11 extending in the vertical direction are provided at four locations around the tank, the lower portion of the frame member 11 is fixed to the apparatus base 2, and the upper portion of the frame member 11 is a ring-shaped bunt 12 provided around the tank. Secure to. A lifting bracket 4 is installed at the upper end of the frame member 11 and is lifted by the bracket.

  When lifting a heavy object having a height, the load tends to become unstable if the object to be conveyed is suspended at a position lower than the center of gravity. For this reason, it is often performed that a lifting bracket is installed at the top of the object to be transported and lifted from the top. However, since the lifting tank cannot be installed in the tank portion in the resin tank, in such a case, it is necessary to provide a frame and install the lifting bracket on the frame. Although it can be safely lifted in this way, this frame is necessary only when the apparatus is transported, and it needs to be sufficiently strong even though it is unnecessary during normal use. Therefore, there was a problem that the cost burden was large.

JP 2002-348088 A

  The problem to be solved by the present invention is a structure for lifting a transported object while it can be safely transported without damaging the transported object when transporting a transported object having a height. It is providing the protective material for conveyance which can simplify.

  The invention according to claim 1 is a protective material for protecting a conveyed object during conveyance of the conveyed object, wherein the protective material has a plate shape whose height is smaller than the vertical and horizontal directions, and the center of the protective material It has a device opening which is a through hole for inserting into the columnar part of the object to be transported, and a rope opening which is a through hole through which a lifting rope etc. is passed outside the device opening. It is a protective material for conveyance characterized by being.

  The invention according to claim 2 is characterized in that, in the transport protection material, a plurality of cuts are made from the device opening toward the outer edge of the protection material on the wall surface of the device opening. It is a protective material for conveyance.

    According to a third aspect of the present invention, in the transport protection material, a crack prevention hole for preventing a crack from expanding beyond a previously provided cut portion is provided on the back side of the cut. It is the protective material for conveyance characterized by this.

  According to a fourth aspect of the present invention, in the transport protective material, a convex portion is provided on the wall surface of the opening for the device, and the inner diameter of the opening for the device in the convex portion is that of the columnar portion of the object to be transported. It is a protective material for conveyance characterized by being slightly smaller than the outer diameter.

  The invention according to claim 2 is the carrying protective material, wherein the protective material is formed by stacking a plurality of cardboards.

  In the invention according to claim 6, the columnar portion of the object to which the protective material for conveyance is attached has a cylindrical shape with individual differences in outer diameter, and is conveyed by the notches and convex portions provided in the protective material. It is a protective material for conveyance characterized by absorbing individual differences in the diameter of the columnar part.

  According to the seventh aspect of the present invention, the transport protection material is inserted into the columnar portion of the transported object at a position higher than the center of gravity of the transported object, and the lifting bracket provided at the lower part of the transported object The connected lifting rope or the like is a lifting method characterized in that the object to be transported is lifted through the rope opening.

  Even if the lifted transported object is about to fall down, the transported object can be safely lifted without falling because it is supported by the lifting rope at the rope opening of the protective material. In addition, since the lifting frame is not necessary on the side of the object to be conveyed, the structure can be simplified. In addition, the protective material also serves as a cushioning material, and even if the protective material is arranged densely during transportation, the conveyed material does not directly collide with each other because the protective material is present, and the protective material is transported to absorb the impact. It is possible to prevent the product from being damaged.

Plan view of the protective material in the second embodiment of the present invention Plan view of the protective material in the third embodiment of the present invention Perspective view of conventional device

  An embodiment of the present invention will be described with reference to the drawings. 1 is a perspective view showing a lifted state in one embodiment of the present invention, FIG. 2 is a plan view of the protective material of FIG. 1, and FIG. 3 is a perspective view of FIG. For example, in the case of a water softener that removes magnesium contained in water, a tank 1 made of polyethylene and FRP (fiber reinforced plastic) is placed on a metal base 2 and ion exchange is performed in the tank. Resin is packed, and soft water is taken out through raw water through the ion exchange resin. The tank 1 has a vertically long cylindrical shape, and a water flow control device is provided in the upper part of the tank. The apparatus base 2 is provided with a lifting bracket 4 at a position that is symmetric with respect to the apparatus central axis. The lifting bracket 4 is intended to make it easier to hook a rope when lifting with a crane. A bolt sufficiently long than the plate thickness is passed downward through a plate bent downward or a plate protruding horizontally. The shape such as a thing can be freely selected.

  When the water softener that is the object to be transported is lifted by a crane, a plate-shaped protective material 3 that is smaller in height than in the vertical and horizontal directions is used. The protective material 3 is made of a material that has high vertical and horizontal strengths but is easily crushed at the tip, for example, stacked cardboard. Corrugated cardboard is particularly preferable in that it is low in weight and low in cost. The protective material 3 has a device opening 6 at the center in accordance with the outer diameter of the tank 1, and the rope opening 7 is provided at a position away from both the outer edge of the protective material 3 and the device opening 6. Open. It is necessary to match the opening 7 for the rope with the position where the lifting metal fitting 4 is provided, and this is also provided at least at two positions symmetrical to the central axis of the protective material. When the protective material 3 is a quadrangular shape, a relatively wide portion is formed at the four corners of the protective material 3, so that the rope openings 7 are preferably provided at the four corners.

  The device opening 6 of the protective material 3 is provided with a convex portion 8 on the peripheral wall. The convex portions 8 are arranged at intervals on four sides of the device opening 6, and the inner diameter of the device opening 6 at the portion where the convex portion 8 is provided is slightly smaller than the outer diameter of the tank 1. Keep it like that. In the case of a tank in which a FRP band is wound around a polyethylene container to increase pressure resistance, a relatively large individual difference occurs in the outer diameter of the tank. The inner diameter of the convex portion 8 of the device opening 6 is made smaller than that of a small tank outer diameter. A notch 9 is cut in the convex portion 8 from the device opening 6 toward the outer edge of the protective material 3. The incision extends from the upper surface to the lower surface of the protective material 3, and a crack prevention hole 10 is formed in the back side of the incision 9 so that the incision does not expand beyond the range in which the incision 9 is made. .

  At the time of packaging after manufacturing the water softener, the device opening 6 of the protective material 3 is aligned with the tank 1 of the water softener, and the protective material 3 is inserted so as to be pushed in from above the tank. The inner diameter of the convex portion 8 of the device opening 6 is smaller than the outer diameter of the tank 1, but if the protective material 3 is inserted while applying force, the tip of the convex portion 8 is crushed and pushed in. be able to. In the portion where the tip of the convex portion 8 is crushed, a force to restore is generated, and the force is a force that presses against the tank 1 from the protective material 3, so that the protective material 3 is fixed to the tank 13. Become. Furthermore, when the force is applied in the direction in which the diameter of the device opening 6 is expanded by pushing the protective material 3, the portion of the notch 9 is gradually opened. A force for returning to the original portion is also generated in the notch 9, and this force also acts as a force for fixing the protective material 3 to the tank 1. In addition, by providing the crack prevention hole 10 in the back of the notch 9, even if a force to open the cut 9 is applied, it is possible to prevent the crack from occurring on the back side of the crack prevention hole 10. Yes.

  When lifting with a crane when moving the water softener, the lifting rope 5 is hung on the lifting bracket 4 through the opening 7 for the rope. The lifting rope 5 can be a wire rope, chain, fiber rope, belt sling, or the like. If the two lifting ropes 5 are hung on the two lifting brackets 4 respectively, the water softener is supported at the four lifting brackets 4 and the two rope openings 7. . That is, the lower lifting bracket 4 provides vertical support, and the upper rope opening 7 provides horizontal support. Since the lifting rope 5 passes through the rope opening 7, even if the water softener is lifted at a position lower than the center of gravity, the water softener does not fall down and can be moved safely.

  Further, the protective material 3 plays a role as a cushioning material. The protective material 3 prevents the products from directly colliding with each other when they are arranged in close proximity, such as when they are stored in stock or transported by truck. Therefore, the product can be prevented from being damaged.

  In addition, both the convex part 8 and the notch 9 fix the protective material 3 with a to-be-conveyed object, and you may provide only one. The protective material 3 can be used for products having various shapes by changing the shape of the device opening 6. For example, if the object to be transported is a quadrangular prism shape, the opening 6 for the device may be substantially rectangular as shown in FIG. In FIG. 4, a large number of convex portions 8 having a triangular cross section are provided. The tip of the triangular convex portion 8 is very easily crushed, and becomes gradually less crushed toward the base side of the convex portion 8. The protective material 3 is fixed by crushing the tip of the convex portion 8 provided on the entire circumference. In FIG. 5, a large number of notches 9 are provided on the entire periphery of the opening 6 for the apparatus. In this case, the diameter of the device opening 6 is set to be the same as or slightly smaller than the outer diameter of the columnar portion of the object to be transported, and when the protective material 3 is pushed in, the peripheral wall is formed around the entire circumference of the device opening 6. Expansion of the inner diameter of the opening 6 for the device by crushing and expansion of the diameter by opening the notches 9 provided on the entire circumference little by little occur.
