  As a structure for preventing an article loaded on a pallet (loading platform) from dropping off from the pallet, a structure in which an enclosure frame surrounding the load on the loading platform is integrated with the pallet (for example, Patent Documents 1 and 2) There is a structure (for example, Patent Document 3) in which a pallet is fitted into an enclosure frame.

Japanese Patent Laid-Open No. 10-250731 JP-A-6-127548 Japanese Utility Model Publication No.57-28758

  In the conventional example, the structure in which the pallet and the enclosure frame are integrated is used when the article is moved without any trouble by using only the pallet (as a so-called flat pallet) such as when moving by a forklift over a short distance. The enclosure frame is unnecessary and has the disadvantage that it becomes an obstacle when unloading, and the structure with a pallet fitted into the enclosure frame does not adopt a structure in which the enclosure frame receives the load in relation to the pallet. When lifting with a crane, it is necessary to hook the hook of the crane to the pallet side.

  The present invention pays attention to such drawbacks of the conventional example, and can easily make a pallet (flat type) that moves using a forklift into a state in which a crane can be lifted while an article is loaded. The invention was devised for the purpose of providing a crane handling and transporting tool capable of detaching the present transporting tool while an article is loaded on a pallet.

  A rectangular cylindrical frame surrounding a rectangular pallet having a fork insertion port of a forklift and being arranged in a self-supporting manner, and a pallet support for the assembly between the opposing side walls of the enclosure through the insertion port. The basic means is to have a configuration with materials.

  And when it is composed of a pallet made up of upper and lower plates and digits interposed between the upper and lower plates, such as a so-called wooden pallet, the shielding material is placed between the upper and lower plates side by side with the pallet support material. If this is the case, it is possible to prevent the fall of small articles through the gap between the upper plates due to the collapse of the articles on the upper plate by making the gap narrow by the presence of the shielding material as much as possible. Occurrence can be prevented, and there is no problem in using a so-called wooden pallet having an existing structure.

  In addition, if the pallet support material is provided with a cylinder for inserting and removing the fork of the forklift, the forklift can be moved to the lifting work place by the crane while being able to lift the crane. .

  According to the present invention, falling and scattering of articles from the pallet during the lifting operation by the crane can be surely prevented by the presence of the surrounding frame, and the state in which the articles are loaded on the pallet by application of the receiving material. Assembling and separation of the pallet and the enclosure can be done freely. Therefore, lifting work using an existing pallet, moving work with a forklift, or unloading and unloading work on the pallet can be performed smoothly. Providing practically superior products.

  FIG. 1 shows an embodiment of a crane cargo handling equipment according to the present invention. FIG. 1 is a rear view of a state in which an enclosure frame and a receiving material are combined with each other, and FIG. 2 is a part of a state in which the materials are combined with each other. FIG. 3 is a bottom view of FIG.

  The crane cargo handling and transporting device of the embodiment includes an enclosure frame 2 that surrounds a rectangular pallet 1 and is arranged in a self-supporting state (on the floor surface), and opposing side walls 2a and 2a (configured of a shape steel). It is composed of a frame and a perforated sheet stretched around the frame, but the structure is not limited), and it is constituted by a support material 3 that is arranged so as to span through the pallet 1. In the case of the embodiment, the pallet 1 is a so-called wooden pallet (configured by interposing a 1c between the upper plate 1a and the lower plate 1b) (when using the wooden pallet), and the supporting material 3 As in the case of the support material 3, the shielding material 4 (the leg pieces 4 b are arranged on both sides along the longitudinal direction of the main plate 4 a made of a perforated plate) arranged between the side walls 2 a and 2 a through the pallet (wood) 1. A so-called resin pallet provided with a fork insertion port on the side surface of the forklift for preventing the fall of small articles from between the upper plates 1a, 1a of the pallet 1 due to load collapse. In this case, since the gap between the upper plates 1a and 1a is not provided like a wooden pallet, the use of the shielding material is omitted.

  The enclosure frame 2 is composed of a rectangular cylinder composed of a pair of opposing side walls 2a, 2a, 2b, 2b, which is constructed by stretching a wire mesh (or a sheet body such as a metal plate) on the frame body, A pair of opposing side walls 2a, 2a is provided with a retaining ring 7 that is used for retaining a hook of a crane, and a pair of opposite side walls 2b, 2b are projected downward from the other pair of opposing side walls 2b, 2b. The assembly ports 6 and 6 and the support port 8 for the shielding material 4 are provided. The support port 8 is disposed so as to interpose the assembly port 6 and forms the base of the enclosure frame 2 together with the assembly port 6. The groove-shaped support portion pieces 8a and 8a are provided relative to the lower surface of the frame body constituting the side wall 2a, and the assembly port 6 is also formed into a U-shaped receiving portion on the lower surface of the frame body. A piece 6a is provided.

  The support material 3 is configured by setting the width between the forks of the forklift on both sides of the central rod 3a, and by providing side rods 3b and 3b relative to each other between the side walls 2a and 2a (assembly ports 6 and 6). The side rod 3b is formed of a rectangular cylinder having an inner diameter into which the substantially rectangular assembly port 6 is inserted, and the free end side is opened so that the fork can be inserted from the free end.

  In addition, when the through hole 10 is provided in the upper surface of the center rod 3a of the receiving material 3 and the receiving material 3 is assembled to the pallet 1 and the enclosure frame 2 through the assembling port 6, the through hole 10 is formed in the enclosure frame 2. Engage with the lock rod 12 so as to be aligned with the receiving tube 11 provided on one side wall 2a and to be hooked to the receiving tube 11 and the through hole 10 (in a French drop style). The support 3 is prevented from being detached from the enclosure frame 2.

  In the figure, 13 is a handle of the receiving material 3, and 14 is a handle of the shielding material 4.

  Thus, the pallet 1 is encased in such a state that an article is loaded (the article can be moved by inserting a fork into the insertion port between the upper and lower plates 1a and 1b on the pallet 1). The frame 2 is placed in a self-supporting state, and the side flanges 3b, 3b of the support member 3 are respectively installed on the side walls 2a of the pair of opposing side walls 2a, 2a of the enclosure frame 2 in the assembling port 6 When the pallet 1 is engaged with the assembly port 6 of the other side wall 2a through the insertion port between the upper and lower plates 1a and 1b through the pallet 1, the pallet 1 loaded with articles is disposed so as to surround the pallet 1 The enclosed frame 2 is in a state of being assembled with each other via the support material 3, and further, the shielding material 4 is passed from the support port 8 side on the side wall 2a side to the top of the pallet 1 and between the lower plates 1a and 1b. Insert into the support port 8 on the other side wall 2b side. Then, when the shielding member 4 is supported by the support pieces 8a and 8a and lifted by a crane using the retaining ring 7, the load on the pallet 1 side including the article in the receiving member 3 is loaded. Is loaded and the surrounding frame 2 (side wall 2a) receives this, so that the lifting work can be performed stably. Note that, for example, a rod-shaped reinforcing member may be stretched over the upper end of the surrounding frame 2 so as to straddle between the opposing side walls. And even if an article collapses and the article is scattered on the pallet 1, there is a shielding material 4 below the pallet upper plate 1a (the gap a generated between the pallet upper plates 1a and 1a is made as narrow as possible). Thus, it is possible to prevent the article (small article) from falling from the pallet 1 and to prevent an accident caused by the fall.

  Further, in the embodiment, since the side rod 3b of the support member 3 is formed of a rectangular cylindrical body having an open free end, the pallet 1 assembled to the enclosure frame 2 by the support member 3 is The forklift can be moved by inserting a fork into the side rod 3b.

  In any case, since the pallet 1 side and the enclosure frame 2 side are free from each other by removing the support material 3 after the movement of the article, the unloading operation of the article on the pallet 1 by removing the enclosure frame 2 is performed. It is possible to obtain a state where it can be easily performed.
