Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a three-dimensional structure in which long materials such as steel bars, steel pipes, shaped steels, etc. are stacked in a plurality of stages without relying on a costly means such as a three-dimensional warehouse. The long material carrier that can be stored in the long material carrier and can easily and quickly take out the long material to be delivered from any length of the long material carrier, and the length that can be achieved thereby. BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for handling a scale material and a long material conveying system.

[0002]

2. Description of the Related Art Conventionally, various methods have been put to practical use for storing and carrying long products such as long steel products and long pipes. For example, Japanese Examined Patent Publication No. 56-13436 discloses a plurality of long U-shaped products formed by a longitudinal member and a pair of longitudinal members for storing and carrying long products such as long steel products and long pipes. Place a long object over the cargo bed of the above, and suspend and support the suspending tool suspended and supported by the overhead traveling crane to each cargo bed, and lift the long object together with the cargo bed by the overhead traveling crane. After that, the long object is lowered together with the loading platform to ground the loading platform, and then the lifting device is detached from the loading platform. In this way, in order to store and transport a long object using the loading platform, it is necessary to disengage the loading platform and the suspenders, that is, sling it. Conventionally, a downward U-shaped hook is attached to a pair of vertical members of the loading platform. A pair of hanging shafts are horizontally attached to the mounting and hanging devices, and the loading platform and the hanging device are slung by locking and releasing the hanging shafts from the hooks.

However, in the one disclosed in Japanese Patent Publication No. 56-13436, it is necessary to finely operate the crane while visually observing the hook and the hanging shaft in order to disengage the hanging shaft of the hanging device from the hook of the bed. The operation becomes very troublesome. FIG. 7 is a perspective view showing a transportation mode using a conventional hanging tool. In the transportation mode using the conventional hanging tool shown in FIG. 7, there is a problem that the hanging shaft 26 must be visually hooked on the hook 20 of the cradle 24.

Therefore, in Japanese Unexamined Patent Publication No. 6-26337, a hook 20 having a downward concave portion is formed in the vertical member 4 on both sides by the longitudinal member 28 and the vertical members 4 on both sides as shown in FIG. The invention using a cradle 24 fitted with is disclosed. Using two cradle 14 shown in FIG.
In the meantime, as shown in FIG. 8, the long material 22 is loaded, slid and transported by a crane to a predetermined steel material storage location. FIG. 9 shows a group of long members 22 transported and stacked in a storage location. The longitudinal direction of the cradle 24 and the longitudinal direction of the long material 22 are orthogonal to each other. Further, Japanese Patent No. 2836013 also discloses Japanese Patent Laid-Open No. 6-2.
A cradle 24 similar to the one described in Japanese Patent No. 6337, a dedicated suspending tool 25 that is moved in two directions orthogonal to each other by a crane and is moved up and down, and a downward recess of the hook 20 attached to the dedicated suspending tool 25. Hanging shaft 26 to be engaged
And the hanging shaft 26, which is mounted over the mounting surface on which the cradle 24 is mounted and the dedicated suspending tool 25.
A sling device for engaging and disengaging the hook with the downward recess of the hook 20 is disclosed.

[0005]

However, Japanese Unexamined Patent Publication (Kokai) No. 6-2
The inventions described in Japanese Patent No. 6337 and Japanese Patent No. 2836013 have at least one or more of the following problems. Dedicated suspenders are required. In general, various kinds of actual long materials having different kinds and different sizes are handled such as storage and shipping. In many cases, long materials with uneven lengths are mixed. Therefore, the fixed hanging device 15 having the fixed size shown in FIG. 4 is unsuitable for handling long and short uneven steel materials. This is because it is necessary to have a size that allows for the longest steel material. Further, the suspending tool 15 is a heavy object, and the weight corresponding to that is wasted each time, resulting in loss of power energy of the crane. Further, there is a problem that the cradle 24 shown in FIG. 8 that can be hung by the hanger 25 is limited to only one stage. Since it has to be transported step by step, there is a problem that the process becomes long and the transportation system becomes stagnant. (2) It is difficult to handle arbitrary stacked cradle. As shown in FIG. 5, when the desired long material cradle 245 to 241 is stacked in multiple stages (in FIG. 5, five stages are stacked), when only the desired long material cradle is to be taken out, for example, five stacked When it is desired to take out the second cradle 242 from the above, in the conventional case, the fifth stage (245), the fourth stage (244), the third stage (243),
As schematically shown in FIGS. 5A to 5F, there is a problem that the second stage cradle 242 must be transported only after being sequentially removed by the crane. (3) Handling of the stacked bottom cradle is troublesome. In addition to the problem described in (2) above, if the stacked bottom cradle is to be transported to another place, the fifth stage (2
45) The fourth stage (244), the third stage (243), the second stage (242), and after removing the cradle, the lowermost cradle (241) must be transported to another place. There are challenges. That is, there is a problem that handling is complicated. Therefore, the present invention is that the above-mentioned special hanging device is essential,
A long material carrier that can solve at least one or more of the problems of the prior art such as the difficulty of handling stacked arbitrary long material carriers and the trouble of handling the lowest cradle, and handling of long material using the same The purpose is to provide a legal and long material transportation system.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 shows an example in which the long material carrier 1 according to the present invention is stacked in four stages. The long material loading platform 1 is a loading platform that has an upward U-shape due to the longitudinal members 2, the widthwise members 3, the vertical members 4, and the columns 5 that are arranged parallel to the longitudinal direction of the long material. The long material carrier 1 is stacked in the order of an initial stage carrier 11, a second stage carrier 12, a third stage carrier 13, and a fourth stage carrier 14. The depth direction of the paper is the longitudinal direction,
A long material (not shown), such as a long steel material having a different diameter, kind, length, etc., is held. A link member 7 rotatably attached around a connecting pin 6 is disposed at both ends of the long material carrier, and a connecting rod 8 is rotatably attached to the other end of the link member 7. ing. For example, the connecting rod 8 of the fourth-stage loading platform 14 is loosely inserted into the hook 20 of the third-stage loading platform 13 stacked on the lower stage. In the present invention, the connecting rod 8 and the hook 20 may be engaged with each other, but may be loosely inserted. When slinging the stacks of stacked long materials with a crane, even if it is loosely inserted with a clearance, it will follow the self-weight and align properly.
At an actual work site, it is difficult to accurately stack each of the long material loading platforms at a fixed position, and it is possible to absorb a positioning error if loosely inserted. The link member 7 rotates and the hook 20 of the lower long material carrier is rotated.
The desired long material loading platform (long material loading platform group) is integrated into one, and the hook 20 of the uppermost long material loading platform is hooked with a wire and lifted by a crane, so The loading platform for the scale material is taken out at the same time. In addition,
In the example of FIG. 1, the first-stage loading platform 11 is fixed to the warehouse floor with three anchor bolts 30.

FIG. 2 is a perspective view showing a state in which the three-stage long material carriers 11 to 13 are connected and integrally suspended by a crane. Since the lower two steps 12 and 11 are integrated by the connecting means, the wire may be passed through the hook 20 of the long material carrier 13 at the uppermost step and hung from the hanging hook 29 of the crane. According to the present invention, it is possible to carry out multi-stage suspension, as compared with the conventional case where only one stage can be carried. That is, the present invention is a long material loading platform that can be stacked in multiple stages to form a loading platform 11, 12, 13 that is upwardly U-shaped for loading a long material (not shown). A longitudinal member 2 parallel to the direction, a pair of vertical members 4 standing upright at both ends of the longitudinal member 2, pins 6 standing upright on the vertical member 4, and arranged on the vertical member 4. Two hooks 20 each having a downwardly facing concave portion, and a hook 20 for a long material carrier which is rotatably attached to the pin 6 and whose other end is a free end and is placed on the lower stage when stacked in multiple stages. And a link member 7 that engages with the long material carrier. However, in the present invention, the connecting means for connecting the multi-stage long material carrier 1 is shown in FIG.
The connection means is not limited to the one illustrated in FIG. 2, and a mechanically known connection means or, in some cases, an electromagnet or the like can be used. Further, it is also possible to use a hybrid type connecting means of an electromagnet and a mechanical connecting means, that is, a composite type connecting means.

The guide guide 21 illustrated in FIG. 2 is integrally attached to the long material carrier 1, and guides and guides when stacking the columns 5 of the lower long material carrier 1 without any deviation. It is designed to be stackable. In the actual work, it is difficult to stack properly because it sways when stacking with a crane. However, when the guide guide is added in the present invention, the link members can be more easily inserted into the hook even when they are stacked in a shifted state. No precision is required due to this play.

FIG. 3 (a) is a plan view of the long material carrier 1 according to the present invention. The long material carrier 1 includes a longitudinal member 2, a width member 3, and a longitudinal member 2, which are arranged parallel to the longitudinal direction of the elongated material.
The vertical member 4 and the column 5 form an upward U-shape. Figure 3
FIG. 3B shows a state in which the connection is suspended as shown in FIG. 2, and FIG. 3C shows a state in which the connection is released by unloading the floor surface.

According to the present invention, it is possible to construct a long-material transport system for simultaneously taking out one or more arbitrary long-material cargo beds 1 from the multi-tiered long-material cargo bed group simultaneously and more quickly than in the conventional case. . In the conventional long material transport system, FIG.
As shown for each process in (a) to FIG. 5 (f), for example, when it is desired to take out the cradle 242, it is necessary to take out the upper cradle 245, 244, 243 one by one. Further, according to the present invention, since each long material carrier 1 can be connected and disconnected by the detachable connecting means 17 as required, it is possible to take out in multiple stages at the same time. For example, in the case of stacking 5 layers, the 3rd and 4th layers from the top can be taken out at the same time. Also, in the case of stacking 5 layers, after moving all 5 layers to a predetermined place, remove the upper link member connected to the lowermost loading platform and leave only the lowermost loading platform in place, leaving the remaining 4 It is also possible to put the steps together and restore them.

FIG. 4 (a) shows 2 from the bottom when stacking 5 layers.
An example of a method for taking out the stage for the long material of the stage is shown. FIG. 4B shows another embodiment. In FIG. 4 (a), (a) is 5
Stacked state, (b) a state in which the upper three stages are connected and integrated by the connecting means 17 and hoisted by a crane, (c) is an integrated and hoisted long material platform group that is hoisted by the crane and is lowered to the floor FIG. 3 shows a state in which the target long material carrier at the bottom is taken out. In (b) of FIG. 4 (b), the upper three stages are connected and integrated and hoisted by a crane, and the target long material carrier is left stacked in the lowermost long material carrier, and (c). Shows the state where the target long material carrier is taken out. The transportation can be simplified as compared with the conventional takeout method shown in FIG.

Incidentally, in the conventional long material storage system shown in FIG. 9, if a special hanging tool (not shown) is not used, a certain cradle 24, for example, 2 from the bottom.
When you want to take out the cradle of the third stage, hook the hanging hook (not shown) of the crane on the hook 20 of the cradle 18 of the third stage from the bottom and pull up the top three stages at once, It is possible to leave.
However, in addition to the necessity of the visual positioning described in the above-mentioned problems, it is unstable and unsafe because two cradle 24 are arranged in a direction orthogonal to the longitudinal direction of the long material 22. In some cases, problems such as load collapse, load slip during crane transportation, and load sway occur. Also, in the case of stacking in 5 stages, it is not possible to take out the 3rd and 4th stages from the top together. This is because the handling is limited to each step. On the other hand, according to the present invention, there is an advantage that the degree of freedom in handling the long material is improved. This is because multiple stages can be taken out at the same time. This is also because it is possible to take out freely as illustrated in FIG.

FIG. 6 shows a schematic view of a long material conveying system according to the present invention. Requester 36 for long material 22 from warehouse 31
