In the following detailed description, numerous specific details are set forth in order to provide a thorough understanding of embodiments of the present invention. However, it will be apparent that one or more embodiments may be practiced without such specific details. In other instances, well-known structures and devices are schematically shown in order to simplify the drawing.
<First Embodiment>
[Composition of ten thousand sticks]
First, with reference to FIGS. 1-3, the structure of the ten thousand sticks 1 for steel materials which concerns on 1st Embodiment of this invention is demonstrated. As shown in FIGS. 1 to 3, the wand 1 includes a lower member 11, a pair of intermediate members 12a and 12b, and a pair of upper members 13a and 13b. Moreover, 1st Embodiment demonstrates the case where the bloom S shown in FIG. 4 is stored as steel materials.

  The lower member 11 is an iron plate-like rectangular member. In the following description, as shown in FIGS. 1 to 3, the longitudinal direction of the lower member 11 will be described as the x-axis direction, the width direction as the y-axis direction, and the thickness direction as the z-axis direction. The length of the lower member 11 in the y-axis direction is longer than twice the width of the bloom S to be stored. Further, the length of the lower member 11 in the x-axis direction is shorter than the length of the stored bloom S, and is a length that can be stably supported by intermediate members 12a and 12b described later. It is preferable that the lower member 11 has flexibility so as to bend according to the weight of the steel material stacked as described later.

  The pair of intermediate members 12a and 12b is a member having a prismatic shape made of iron, and extends in the y-axis direction on the upper surfaces (surfaces on the z-axis positive direction side) at both ends in the x-axis direction, which is the longitudinal direction of the lower member 11. Each provided. The length in the y-axis direction, which is the longitudinal direction of the pair of intermediate members 12a, 12b, is the same as the length of the lower member 11 in the y-axis direction. As shown in FIG. 1, the pair of intermediate members 12 a and 12 b are arranged such that the intermediate member 12 a is arranged at the edge of the lower member 11 on the x-axis negative direction side, and the intermediate member 12 b is on the x-axis positive direction side of the lower member 11. By being welded in a state of being arranged at the edge, each is fixed to the lower member 11. Further, as shown in FIG. 3, the pair of intermediate members 12a and 12b is fixed to the lower member 11, and the height h in the z-axis direction of the lower member 11 is greater than the thickness of the claw portion of the forklift described later. Is also formed to be large. Further, the width d in the x-axis direction of the pair of intermediate members 12a and 12b is appropriately set to an optimal length according to the weight of the steel material so as to withstand the weight of the steel material to be stacked.

  The pair of upper members 13a and 13b are iron plate-like rectangular members, and are provided on the upper surfaces of the pair of intermediate members 12a and 12b, respectively. The length of the pair of upper members 13a and 13b in the y-axis direction is the same as the length of the lower member 11 in the y-axis direction. The length of the pair of upper members 13a and 13b in the x-axis direction is shorter than the length obtained by subtracting the width of the claw portion of a forklift described later from the half length of the lower member 11 in the x-axis direction. It is formed so as to be longer than the length obtained by adding the width d of 12a and 12b and the width of the claw portion of the forklift. The pair of upper members 13a and 13b are arranged such that the edge of the upper member 13a on the x-axis negative direction side overlaps with the intermediate member 12a, and the edge of the upper member 13b on the x-axis positive direction side overlaps with the intermediate member 12b. In this state, the intermediate members 12a and 12b are fixed by being welded to each other. Furthermore, it is preferable that the upper members 13 a and 13 b have flexibility like the lower member 11.

  Since the wand 1 has the above configuration, gaps 14a and 14b corresponding to the height h of the intermediate members 12a and 12b are formed between the lower member 11 and the pair of upper members 13a and 13b. Further, as described above, the upper members 13a and 13b are spaced apart in the x-axis direction, whereby the opening 15 is formed on the central upper surface of the wand 1.

[Steel storage method]
Next, a method for storing the bloom S, which is a steel material, using the tens of thousands of sticks 1 according to the first embodiment will be described. In the storage method of Bloom S using tens of thousands of sticks, Bloom S is stored in two types: a method in which it is stored in one stage without being stacked, and a method in which it is stored in multiple stages. Is done.

  When the bloom S is stored in one stage, the bloom S is stored by placing two blooms S1 and S2 on the wand 1 as shown in FIG. At this time, tens of thousands of sticks 1 are placed directly on the ground. By placing the blooms S1 and S2 with the ten thousand sticks 1 between them without directly placing the blooms S1 and S2 on the ground, the stored blooms S1 and S2 can be easily handled as will be described later.

  On the other hand, when the bloom S is stacked and stored, the tens of sticks 1 and the two blooms S1 and S2 shown in FIG. Stacking is performed by stacking at least one other set of ten thousand sticks 1 and bloom S on the side. In the example shown in FIG. 5, two sets of ten thousand sticks 1B and 1C and blooms S3 to S6 are placed on a set of ten thousand sticks 1A and blooms S1 and S2 placed on the ground, so that bloom S1. ~ S6 are stacked in three stages.

  Handling of the wand 1 and the bloom S is performed using a forklift 2 as shown in FIG. The forklift 2 has a pair of claw portions 21a and 21b that protrude in front of the forklift 2 and are provided side by side in the horizontal direction. The pair of claw portions 21a and 21b are provided so as to be movable in the horizontal direction and to be vertically movable. In the first embodiment, the handling of the wand 1 and the bloom S is performed by placing the wand 1 and the bloom S on the pair of claw portions 21a and 21b and handling them. For example, when handling the wand 1, the pair of claw portions 21a, 21b are inserted into the gaps 14a, 14b of the wand 1, respectively, and the pair of claw portions 21a, 21b support the pair of upper members 13a, 13b, respectively. Then lift the wand 1 and handle it.

  With reference to FIG. 7, a method of separately handling the wand 1 and the bloom S and placing the bloom S on the wand 1 will be described. First, as shown in FIG. 7A, the claw portions 21a and 21b of the forklift 2 are inserted into the gaps 14a and 14b of the wand 1, and the pair of claw portions 21a and 21b support the pair of upper members 13a and 13b. Then, the wand 1 is transported to a predetermined installation position. When the wand 1 is conveyed to a predetermined installation position, the pair of claws 21a and 21b are lowered in the negative z-axis direction, and the wand 1 is lowered to the ground G. FIG. 7B shows a state in which the pair of claw portions 21a and 21b are lowered and the wand 1 is lowered to the ground. Next, by moving the forklift 2, the pair of claw portions 21a and 21b are moved in the y-axis direction, and the pair of claw portions 21a and 21b are removed from the gaps 14a and 14b.

  After that, the forklift 2 is used to move the bloom S1 from a transport cart / trailer (not shown) or other tens of sticks 1 to the upper part of the center of the wand 1 as shown in FIG. When the bloom S1 is moved, the pair of claw portions 21a and 21b of the forklift 2 are moved so that the claw portions 21a and 21b come closer to each other in the horizontal direction (x-axis direction) from the state of FIGS. Let At this time, the pair of claw portions 21a so that the length from the x-axis negative direction side end of the claw portion 21a to the x-axis positive direction side end of the claw portion 21b is shorter than the length of the opening 15 in the x-axis direction. , 21b are adjusted. Hereinafter, a state where the claw portions 21a and 21b are separated from each other as shown in FIG. 7A is referred to as a state in which the pair of claw portions 21a and 21b are opened, and the claw portion 21a as shown in FIG. 7C. , 21b are referred to as a state in which the pair of claw portions 21a, 21b are closed. After adjusting the positions of the pair of claws 21a and 21b, the pair of claws 21a and 21b is inserted below the center of the bloom S1, and the center of the lower surface of the bloom S1 (the surface on the negative z-axis side) is paired. The forklift 2 handles the bloom S1 by supporting and lifting the claw portions 21a and 21b. After the bloom S1 is moved above the ten thousand sticks 1, the pair of claws 21a and 21b are lowered and the bloom S1 is placed on the ten thousand sticks 1. At this time, since the pair of claw portions 21 a and 21 b are in a closed state, they are lowered through the opening 15. Therefore, the bloom S1 can be placed on the 10000 bar 1 without the claw portions 21a, 21b coming into contact with the 10000 bar. FIG. 7D shows a state in which the pair of claws 21 a and 21 b are lowered and the bloom S 1 is placed on the ten thousand sticks 1. After the bloom S1 is placed on the wand 1, the forklift 2 is moved to move the pair of claw portions 21a, 21b in the y-axis direction and remove the pair of claw portions 21a, 21b from the inside of the wand 1 .

  In the example shown in FIG. 7, the operation of placing one bloom S1 on the wand 1 is shown. However, the two blooms S1 and S2 are transported simultaneously and placed on the wand 1 as shown in FIG. May be. At this time, the blooms S1 and S2 are arranged in the direction in which the pair of claws 21a and 21b extend and are placed on the pair of claws 21a and 21b for handling. Thereby, the time concerning handling of bloom S1, S2 can be shortened.

  Next, with reference to FIG. 8, the method of handling in the state which mounted the bloom S on the ten thousand stick 1 is demonstrated. In the example illustrated in FIG. 8, as shown in FIG. 4, the tens of thousands of sticks 1 on which the blooms S <b> 1 and S <b> 2 are placed are handled. First, as shown in FIG. 8B, the blooms S1 and S2 are placed and inserted into the gaps 14a and 14b of the wand 1 on which the ground G is placed with the pair of claws 21a and 21b opened. To do. Here, although not shown in FIG. 8B, the bloom S2 exists on the back side of the bloom S1, which is the y-axis negative direction side. Next, the pair of claws 21a and 21b are raised, and as shown in FIG. 8A, the wand 1 is bloomed S1 so that the pair of claws 21a and 21b support the pair of upper members 13a and 13b, respectively. , S2 is lifted together. Further, the wand 1 and the blooms S1 and S2 are moved to a predetermined position while being lifted. After the wand 1 and the blooms S1 and S2 move to predetermined positions, the pair of claw portions 21a and 21b are lowered, the wand 1 is lowered to the ground G, and the state shown in FIG. After the wand 1 is lowered to the ground G, the forklift 2 is moved to move the pair of claw portions 21a and 21b in the y-axis direction, and the pair of claw portions 21a and 21b are removed from the inside of the wand 1 . As shown in the example shown in FIG. 8, by using tens of thousands of sticks 1, not only tens of thousands of sticks 1 and bloom S but also handling tens of thousands of sticks 1 with bloom S on top of tens of thousands of sticks 1 It becomes possible to do.

  Here, in FIG. 7 and FIG. 8 described above, the operation of placing the bloom S on the ground G has been described, but a plurality of blooms S may be stacked using the operation described in FIG. 7 and FIG. it can. For example, the bar 1A and the blooms S1, S2 are placed on the ground G by the operation shown in FIG. 7 and FIG. 8, and the blooms S1, S2 are further performed in the same manner as the operation shown in FIG. By placing tens of thousands of sticks 1B and blooms S3 and S4 on the top, blooms S1 to S4 can be stacked in two stages as shown in FIG. Although not shown in FIG. 9A, the blooms S2 and S4 exist on the back side of the blooms S1 and S3 on the negative y-axis side. Further, the bloom S can be stacked in a plurality of stages of three or more by repeating the same operation.

  Next, with reference to FIG. 9 and FIG. 10, the operation | movement which takes out the upper bloom S from the bloom S piled up in multiple steps is demonstrated. Although not shown in FIGS. 9 and 10, blooms S2 and S4 exist on the back side of the blooms S1 and S3 on the negative side of the y-axis. In the example illustrated in FIG. 9, the upper blooms S3 and S4 are taken out from the blooms S1 to S4 stacked in two stages. First, as shown in FIG. 9A, the pair of claw portions 21a and 21b of the forklift 2 are inserted into the opening 15 position of the wand 1B corresponding to the second step from the bottom. At this time, the pair of claw portions 21a and 21b are inserted in a closed state. Next, by raising the pair of claws 21a and 21b, the blooms S3 and S4 are lifted as shown in FIG. 9B. Thereby, upper bloom S3, S4 can be taken out from bloom S1-S4 stacked in multiple steps. In the example illustrated in FIG. 9, the case where the stacked upper blooms S3 and S4 are taken out together has been described. However, the bloom S3 can be changed by changing the depth and direction in which the pair of claws 21a and 21b are inserted. , S4 can be taken out.

In the example illustrated in FIG. 10, the upper blooms S3 and S4 are taken out from the blooms S1 to S4 stacked in two stages as in FIG. 9. First, as shown in FIG. 10 (A), the pair of claw portions 21a and 21b of the forklift 2 are inserted into the inside of the wand 1B corresponding to the second step counted from the bottom and overlapped with the pair of upper members 13a and 13b. To do. At this time, the pair of claw portions 21a and 21b are inserted in positions corresponding to the pair of upper members 13a and 13b in an open state. Next, by raising the pair of claws 21a and 21b, the wand 1B and the blooms S3 and S4 are lifted as shown in FIG. Thereby, upper blooms S3 and S4 and ten thousand sticks 1B can be taken out collectively from the blooms S1 to S4 stacked in a plurality of stages.
In the first embodiment, the lower member 11 has flexibility. Therefore, even when the bloom S is warped, the lower member 11 is elastically deformed according to the shape of the warp, so that the bloom S can be stably stacked.

Next, with reference to FIG. 11 and FIG. 12, the structure of the wand 1 which concerns on 2nd Embodiment of this invention is demonstrated. As shown in FIG. 11, the wand 1 according to the second embodiment includes a lower member 11, a pair of intermediate members 12a and 12b, and a pair of upper members 13a and 13b. Unlike the first embodiment, the wand 1 according to the second embodiment includes a lower member 11 and a pair of upper members 13a and 13b made of a plurality of members and having holes 16a to 16h.

  The lower member 11 is an iron plate-like rectangular member, and includes three first plate-like members 111 to 113 and three second plate-like members 114 to 116 as shown in FIG. The three first plate members 111 to 113 extend in the x-axis direction and are spaced apart in the y-axis direction. The three second plate-like members 114 to 116 extend in the y-axis direction so that the second plate-like members 114 and 115 at both ends overlap with both longitudinal ends of the first plate-like members 111 to 113. They are spaced apart in the x-axis direction. Further, the three second plate members 114 to 116 are provided on the lower surface side of the three first plate members 111 to 113 and are welded to the three first plate members 111 to 113.

[Modification]
Although the present invention has been described above with reference to specific embodiments, it is not intended that the present invention be limited by these descriptions. From the description of the invention, other embodiments of the invention will be apparent to persons skilled in the art, along with various variations of the disclosed embodiments. Therefore, it is to be understood that the claims encompass these modifications and embodiments that fall within the scope and spirit of the present invention.

  For example, the shape and dimensions of the wand 1 are not limited to the example of the above embodiment. The lower member 11 and the pair of upper members 13a and 13b may not be rectangular as long as they are substantially plate-like members. Further, the length of the wand 1 in the y-axis direction may be a length capable of mounting one or three or more blooms S. Further, when the length of the bloom S in the longitudinal direction is extremely longer than the length of the wand 1 in the x-axis direction, the bloom S is placed on the tens of sticks 1 arranged in the x-axis direction. It may be stored.

  Moreover, although the said embodiment demonstrated the case where the bloom S was stored as a steel material stored using the ten thousand sticks 1, this invention is not limited to this example. For example, the steel material may be a billet or a slab. FIG. 13 shows a state in which the slab Sa is stored using a tens of thousands of sticks 1. In most cases, the slab Sa is wider than the bloom S. For this reason, as shown in FIG. 13, for example, two ten thousand bars 1A and 1C may be used side by side in the y-axis direction. Further, when the length of the slab Sa is long, two tens of bars 1B and 1D arranged in the y-axis direction are further arranged in the x-axis direction, and the slab Sa is stored using a total of four tens of bars 1A to 1D. To do. Similarly, a plurality of slabs Sa can be stacked by sequentially placing tens of thousands of sticks 1A to 1D and a slab Sa on the slab Sa. Normally, when the slab Sa is stored outdoors, cylindrical refractory cylinders 3A to 3F are used as shown in FIG. And the cylindrical tens of thousands of sticks 3A-3F are conveyed and installed by human power. However, when the temperature of the slab Sa is high, it becomes difficult to install the cylindrical rods 3A to 3F on the slab Sa, so that the slab Sa can be stacked only with the slab Sa cooled to less than 400 ° C. could not. On the other hand, when the ten thousand sticks 1 according to the above embodiment are used, since the ten thousand sticks 1 are transported and installed by the forklift 2, the slab Sa is stacked even when the temperature of the slab Sa is as high as 400 ° C. or higher. be able to. In the example illustrated in FIG. 13, when another slab Sa is placed on the second stage between the slab Sa and the ground, four tens of bars 1A to 1D are placed between the two slabs Sa. Although it was set as the structure provided, the number of the ten thousand sticks 1 provided is not limited. The number of tens of sticks 1 to be provided is appropriately selected according to the size of the slab Sa and the tens of thousands of sticks 1 so that the slab Sa can be stably stored.

  Furthermore, in the said embodiment, although the lower member 11, the pair of intermediate members 12a and 12b, and the pair of upper members 13a and 13b that constitute the wand 1 are made of iron, the present invention is not limited to such an example. The lower member 11, the pair of intermediate members 12a, 12b, and the pair of upper members 13a, 13b are members made of other metals or refractories as long as they have heat resistance and strength to support steel. Also good. For example, by making at least one part of the lower member 11, the pair of intermediate members 12a and 12b, and the pair of upper members 13a and 13b refractory, the weight of the wand 1 can be reduced. The manufacturing cost of the wand 1 can be reduced and the ease of handling can be improved.

Furthermore, in the said embodiment, although the lower member 11 was set as the structure which has flexibility, this invention is not limited to this example. The lower member 11 may not have flexibility as long as steel materials can be stably stacked.
Moreover, although the said embodiment demonstrated the example which conveys steel materials step by step using the forklift 2, this invention is not limited to this example. A plurality of stacked steel materials may be transported simultaneously. For example, from the state in which the blooms S are stacked in three stages as shown in FIG. 5, the four blooms S3 to S6 in the upper two stages may be taken out simultaneously using the method described in FIG. 9 or FIG.

  Furthermore, in the second embodiment, the lower member 11 and the pair of upper members 13a and 13b are composed of a plurality of plate-like members 131a to 135a and 131b to 135b, so that the gaps 16a to 16h are formed. The present invention is not limited to such an example. For example, a hole may be formed in the lower member 11 and the pair of upper members 13a and 13b of the first embodiment to form a hole.

  According to the above configuration, the gaps 14a and 14b are formed between the lower member 11 and the pair of upper members 13a and 13b, respectively, and the claw portions 21a and 21b of a heavy machine such as the forklift 2 are inserted into the gaps 14a and 14b. By lifting, the wand 1 can be easily handled. Further, as shown in FIG. 8, the steel material can be handled together with the tens of thousands of bars even when the steel is placed on the tens of thousands of bars. Moreover, since the tens of thousands of sticks 1 have heat resistance, even when the temperature of the steel material is as high as 400 ° C. or higher, the tens of thousands of bars 1 can be installed on the steel material, and the steel material can be stacked. Furthermore, by forming the opening in the wand 1, only the steel material can be removed from the state where the steel material is placed on the wand 1 as shown in FIGS. 1 and 9. Therefore, even when storing a plurality of steel materials having different steel types and dimensions, the steel materials can be handled individually.

(2) Holes 16a to 16h are formed on the inner surface of at least one of the lower member 11 and the pair of upper members 13a and 13b. According to the above configuration, since the weight of the wand 1 can be reduced, the wand 1 can be manufactured at a low cost and the ease of handling can be further improved.
(3) At least one of the lower member 11 and the pair of upper members 13a and 13b includes a plurality of plate-like members 131a to 135a and 131b to 135b. According to the said structure, the holes 16a-16h as described in said (2) can be formed easily. Moreover, since the dimension of the raw material of the lower member 11 and a pair of upper member 13a, 13b can be made small, the ten thousand stick 1 can be manufactured at low cost.
(4) The lower member 11 has flexibility. According to the said structure, it can pile up stably about the steel material which the curvature produced.
