Description

  The present invention relates to a stacking rack.

  In the transportation of cargo by a container for cargo transportation, cargo is stacked in a storage space in the container, and the cargo is transported together with the container by a transport vehicle or the like. When stacking cargo, a rack for stacking may be used to efficiently stack the cargo (see Patent Document 1).

Japanese Patent Laid-Open No. 2002-321736

  When cargo is stacked on the rack, the position of the center of gravity of the rack is separated from the floor of the container in the height direction, so that the support of the rack on the floor becomes unstable. In particular, when various types and shapes of cargo are mixedly loaded, the center of gravity of the rack is changed to an irregular position in the height direction, so that the support on the floor surface becomes extremely unstable. Due to the unstable support of the rack, the rack is likely to fall down due to the shaking of the container during transportation.

  An object of this invention is to provide the stacking rack which can prevent suitably falling in a container, when cargo is stacked and conveyed.

In order to achieve the above object, a stacking rack according to the present invention has a placing portion for placing a cargo and leg portions attached to the placing portion and supporting the placing portion on the floor surface. Furthermore, it has a stopper which is pressed against the inner wall side surface of the container and fixes the placing portion to the inner wall side surface of the container. And it has a pressing member which makes a stopper protrude toward the inner wall side surface of a container. The stopper is provided so as to be slidable in the length direction of the container.

  According to the stacking rack of the present invention, the entire rack can be fixed to the container together with the placing portion for placing the cargo by the pressing member protruding toward the inner wall side surface of the container. For this reason, even when a container shakes at the time of conveyance, it can prevent suitably that a rack falls in a container.

It has a box-like outer shape extending in the depth direction of the storage space s (the length direction of the container, indicated by arrows aa ′ in FIG. 8). Although omitted in the drawing, a carry-in / out port that partitions the inside and the outside of the container 200 is provided on one end side in the length direction.

  In the storage space s of the container 200, there are a floor 210 on which the rack 10 is installed, a side wall 220 against which the support plate 90 is pressed, and a ceiling 230 (see FIG. 9). Under the floor 210 of the container 200, a steel bottom side rail 240 is laid along the length direction of the container 200 (see FIG. 10). The bottom side rails 240 are arranged in pairs on both sides of the container 200 in the width direction. The laid bottom side rail 240 constitutes the foundation of the floor 210 of the container 200.

  The bottom side rail 240 has a flooring angle 251 for supporting the iron plate 213 and the wooden plywood 215 constituting the floor 210, a side wall angle 252 for attaching the side wall 220, and a cross for reinforcing the strength of the floor 210. The member 253 is welded (see FIG. 9). An iron plate 213 and a wooden plywood 215 are stacked on the flooring angle 251 welded to the bottom side rail 240 to form the floor 210 of the container 200.

  The cross members 253 are installed at a certain interval in the length direction of the container 200 (indicated by arrows aa ′ in FIG. 10). Each cross member 253 is disposed so as to be orthogonal to the length direction of the container 200. The cross member 253 is made of steel.

  The side wall 220 is welded to the side wall angle 252 so as to be positioned in the vicinity of just above the bottom side rail 240 (see FIG. 9). The side wall 220 uses a flat iron plate processed into a concavo-convex shape, and has a corrugated inner surface that is concavo-convex along the length direction of the container 200 (see FIG. 11).

  Next, the rack according to the embodiment will be described.

  1 to 4, the rack 10 includes a placement portion 30 on which the cargo c is placed and four leg portions 50 that support the placement portion 30. The mounting portion 30 is formed with a flat mounting surface 31 for stably loading the cargo c. The leg portion 50 is formed in a column shape extending from the placement portion 30. The legs 50 are connected to each other by a connecting member (corresponding to a connecting member) 55 extending in the length direction of the container (indicated by an arrow aa ′ in FIG. 1).

  The mounting portion 30 of the rack 10 is formed by welding steel materials arranged in a lattice shape with a certain interval in the vertical and horizontal directions. The weight of the rack 10 is reduced by forming the mounting portion 30 with steel materials arranged in a lattice shape.

  The plurality of steel materials arranged in a lattice form a mounting surface 31 on which the cargo c is placed. A supporting plate 90 is attached to the steel material 41 arranged along the length direction of the container 200 among the steel materials forming the outer peripheral portion of the placement surface 31. As the steel material 41, a grooved steel having a groove 45 formed so as to be recessed from the mounting surface 31 is used (see FIG. 2).

  A part of a slide mechanism 130 for attaching the support plate 90 to the rack 10 so as to be slidable is installed in the groove 45 of the steel material 41 (see FIGS. 2 and 5). A portion of the steel material 41 where the slide mechanism 130 is provided is exposed to the outside by the groove 45. For this reason, the operator can easily adjust and maintain the slide mechanism 130.

  Among the steel materials forming the outer peripheral portion of the mounting surface 31, the steel material 43 disposed along the width direction of the container 200 (the direction of the arrow bb ′ in FIGS. 1 and 2) An L-shaped angle 60 extending toward the floor surface 211 is attached.

  The L-shaped angle 60 constitutes a part of the leg portion 50. The leg part 50 is comprised by the 1st member 60 which consists of an L-shaped angle, the 2nd member 70 connected with the 1st member 60, and the 3rd member 80 connected with the 2nd member 70 (FIG. 3).

  An insertion space 61 for inserting the second member 70 is formed in the first member 60 (see FIG. 6B). An insertion space 81 for inserting the second member 70 is also formed in the third member 80 (see FIG. 7A). With the upper part of the second member 70 inserted into the insertion space 61 of the first member 60 and the lower part of the second member 70 inserted into the insertion space 81 of the third member 80, the second member 70 and the first member 60 and The leg portion 50 is configured to be connected to each of the third members 80. Steel is used for the first member 60, the second member 70, and the third member 80.

  The connection between the first member 60 and the second member 70 is performed using a swinging butterfly bolt 71 and a support block 73 (see FIGS. 6A and 6B).

  A part of the second member 70 is inserted into the insertion space 61 of the first member 60 while the support block 73 is placed along the guide hole 63 provided in the first member 60. By using the guide hole 63 and the support block 73, the connection work can be smoothly performed. With the second member 70 inserted into the insertion space 61 of the first member 60, the anti-swing butterfly bolt 71 is fastened and fixed. In order to prevent loss of the anti-swing butterfly bolt 71, the anti-sway butterfly bolt 71 is connected to a chain fixing portion 67 provided on the first member 60 via a chain 68.

  The anti-swing butterfly bolt 71 for connecting the first member 60 and the second member 70 can be fastened from the inside of the leg portion 50 (see FIG. 4). This is because, when the legs 50 are assembled, it is possible to prevent the cargo c loaded inside the rack 10 from being damaged by the tip portion of the anti-swing butterfly bolt 71.

  The leg part 50 is provided with the folding mechanism 170 for folding the leg part 50 (refer FIG. 6 (A), (B)). The folding mechanism 170 includes a long hole 171 provided in the second member 70, a bolt 173 that guides the second member 70 to move along the long hole 171, and a nut 175 for fastening the bolt 173. It is composed by. As will be described later, a plurality of racks 10 can be stacked in a state in which the legs 50 are folded (see FIG. 13).

  The leg 50 is folded in a state where the fixing by the swing-proof butterfly bolt 71 is loosened. The second member 70 is moved downward (arrow d direction) in FIG. 6 along the long hole 171 along the bolt 173. At this time, the support block 73 is removed from the guide hole 63 provided in the first member 60. The second member 70 is rotated at the end 177 of the elongated hole 171 using the bolt 173 as a fulcrum. When the second member 70 is folded inward, the entire leg portion 50 is folded in a state where the first to third members 60, 70, 80 are connected. In addition, in FIG. 3, the state by which the leg part 50 is folded by the arrow r is shown.

  The placing portion 30 is provided with a rope 35 for lifting the leg portion 50. The rack 10 can be stacked in a state where the legs 50 are lifted, and the workability can be improved.

  The first member 60 constituting the leg portion 50 is provided with a stacking block 180 (corresponding to a guide member) that prevents the rack 10 in which the leg portions 50 are folded and stacked from each other from being displaced. See).

  The stacked block 180 is provided integrally with the steel material 43 constituting the placement unit 30. The stacked block 180 is formed with an inclined surface 181 that exhibits a guide function for determining the stacked position. When the racks 10 a and 10 b are stacked, the lower end portion 65 of the first member 60 of the rack 10 a stacked on the upper stage is disposed in the recess 47 formed by the steel materials 41 and 43. Using the stacked block 180, the inclined surface 181 of the stacked block 180, and the inclined surface 48 of the recess 47, it is possible to perform a stacked operation while positioning the stacked position. After the stacking, the end portion 65 of the first member 60 of the rack 10a stacked in the upper stage can be rested by the stacking block 180 and the inclined surface 48 of the recess 47.

  For the connection between the second member 70 and the third member 80, a height adjusting bolt 151 and a snap pin 155 are used (see FIG. 7).

  The height adjustment bolt 151 is inserted into each of the height adjustment hole 153 provided in the second member 70 and the connection hole provided in the third member 80, and the snap pin 155 is inserted into the height adjustment bolt 151. And consolidate.

  The third member 80 is provided with a chain fixing portion 87. A chain 88 is attached to the chain fixing portion 87. The height adjusting bolt 151 and the connecting pin 155 are connected to the chain fixing portion 87 via the chain 88. This is to prevent the height adjusting bolt 151 and the connecting pin 155 from being lost.

  The height adjusting bolt 151 can also be fitted from the inside of the leg portion 50. When the leg portion 50 is assembled, it is possible to suitably prevent the cargo c loaded inside the rack 10 from being damaged by the tip portion of the height adjusting bolt 151.

  The height adjusting bolt 151 and the height adjusting hole 153 constitute a height adjusting mechanism 150 for adjusting the height of the leg portion 50.

  A plurality of height adjustment holes 153 are provided at regular intervals in the height direction. When changing the height of the leg portion 50, the second member 70 and the third member 80 are connected by shifting the height adjustment hole 153 to be connected. Since the connection position of the third member 80 with respect to the second member 70 is changed, the height of the leg portion 50 and the rack 10 as a whole is changed.

  In the second member 70 in the embodiment, five height adjustment holes 153 are provided at 100 mm intervals at different positions in the height direction (see FIG. 3). Therefore, the height of the leg portion 50 can be adjusted in five steps every 100 mm.

  The legs 50 are connected to each other by a connecting member 55 extending in the length direction of the container 200. The connecting member 55 supports the placing part 30 on the floor surface 211 of the container 200 together with the leg part 50 (see FIG. 4, the length direction of the container 200 is indicated by aa ′ in the figure).

  When the leg part 50 is formed in a column shape, the area of the installation surface of the leg part 50 on the floor surface 211 of the container 200 is relatively small. Since the load concentrates on the place where the leg portion 50 is installed on the floor surface 211 of the container 200, the floor 210 of the container 200 is easily pulled out.

  A plurality of cross members 253 are installed under the floor of the container 200 in order to reinforce the strength of the floor 210 (see FIGS. 9 and 10). In order to effectively prevent the floor 210 of the container 200 from slipping out when the leg portion 50 is formed in a pillar shape, the container 200 is spaced in the length direction so as to straddle more cross members 253. It is necessary to install the leg portion 50 with a gap. For this reason, the installation position of the rack 10 in the container 200 is restricted, or it is necessary to attach a leg portion 50 with a large dimension in the length direction of the container 200.

  The connecting member 55 attached to the leg part 50 supports the mounting part 30 on the floor surface 211 in the container 200 together with the leg part 50 (see FIG. 10). Since the rack 10 can be supported by distributing the load to the plurality of cross members 253 via the connecting members 55, it is possible to effectively prevent the floor 210 of the container 200 from coming off. For this reason, the freedom degree of the installation position of the rack 10 increases. Furthermore, since it is not necessary to make the dimension between the leg parts 50 in the length direction of the container 200 excessively large, the rack 10 can be manufactured with a compact dimension.

  When the rack 10 is stored in the container 200, it is desirable that the connecting member 55 be disposed directly above or around the bottom side rail 240 via the floor surface 211 of the container 200 (see FIG. 10).

  Below the floor of the container 200, there is a bottom side rail 240 laid along the length direction of the container 200. The strength of the floor surface 211 is relatively high in the vicinity of the portion where the bottom side rail 240 is laid on the floor 210 of the container 200 as compared with other portions. By arranging the connecting member 55 extending in parallel with the bottom side rail 240 directly above or around the portion where the bottom side rail 240 is laid, the rack 10 is placed at a portion where the strength of the floor surface 211 of the container 200 is relatively high. It becomes possible to support. As a result, it is possible to more reliably prevent the floor 210 of the container 200 from falling out when the rack 10 is installed. As shown in FIG. 9, when the side wall 220 of the container 200 is disposed immediately above the bottom side rail 240, the connecting member 55 can be installed close to the bottom side rail 240. It is desirable to design the rack 10.

  The supporting plate 90 for fixing the mounting portion 30 to the inner wall side surface 221 of the container 200 and the pressing member 110 for projecting the supporting plate 90 toward the inner wall side surface 221 of the container 200 include the mounting portion 30. It is integrally attached to the steel material 41 which comprises (refer FIG. 5).

  By pressing the support plate 90 against the inner wall side surface 221 of the container 200, the placement unit 30 can be fixed to the inner wall side surface 221 of the container 200 (see FIG. 12B). By fixing the mounting portion 30 to the container 200, the entire rack 10 including the leg portions 50 connected to the mounting portion 30 is fixed to the inner wall side surface 221 of the container 200.

  The support plate 90 includes a pressing surface 91 that is pressed against the inner wall side surface 221 of the container 200, and a connection portion 95 for connecting the pressing bolt 111 (FIGS. 5A and 5B). See).

  The connection part 95 is formed by welding a plate bent into a rectangle to the support plate 90. The connection portion 95 is provided with a holding hole 96 for hooking a nut 112 that can be attached to the pressing bolt 111. A nut 112 is hooked on the holding hole 96 to connect the pressing bolt 111 and the support plate 90. The support plate 90 is held so as to be rotatable independently of the pressing bolt 111 through the holding hole 96. The support plate 90 is prevented from rotating with the rotation of the pressing bolt 111. In addition, the rotation angle of the support plate 90 around the axis of the pressing bolt 111 can be arbitrarily adjusted.

  When the mounting portion 30 is fixed to the inner wall side surface 221 of the container 200, the support plate 90 is pressed against the concave portion 223 of the inner wall side surface 221 of the container 200 (see FIG. 12B).

  Between the concave portion 223 and the convex portion 224 of the inner wall side surface 221 of the container 200 formed in a corrugated shape, there is an inclined portion 225 that is inclined toward the inside of the container 200. The inclined portions 225 adjacent to both sides of the concave portion 223 against which the support plate 90 is pressed exhibit a function of preventing the support plate 90 from being displaced in the length direction of the container 200. Since the support plate 90 is pressed against the concave portion 223 of the inner wall side surface 221 of the container 200, the support plate 90 is pressed as compared with the case where the support plate 90 is pressed against the convex portion 224 of the inner wall side surface 221 of the container 200. It is possible to effectively prevent deformation and dent of the inner wall side surface 221 of the container 200.

  The pressing surface 91 pressed against the inner wall side surface 221 of the support plate 90 is formed in a shape that matches the surface shape of the inner wall side surface 221 of the container 200 (see FIG. 12A).

  The pressing surface 91 of the support plate 90 includes a flat portion 92 that matches the concave portion 223 of the inner wall side surface 221 of the container 200, and a rib portion 93 that matches the inclined portion 225 connected to the concave portion 223.

  The rib portion 93 effectively prevents the support plate 90 from being displaced while the flat portion 92 maintains the pressing against the concave portion 223. Since the displacement of the support plate 90 is prevented, the rack 10 can be more firmly fixed to the inner wall side surface 221 of the container 200.

  The support plate 90 is provided with an anti-slip elastic member 98 (see FIG. 12A).

  A pressing surface 91 of the support plate 90 is formed by the elastic member 98. The elastic member 98 prevents the support plate 90 pressed against the inner wall side surface 221 from slipping and being displaced. The placement unit 30 can be more firmly fixed to the inner wall side surface 221 of the container 200. The elastic member 98 also exhibits a function of suitably preventing the inner wall side surface 221 of the container 200 from being scratched or dented.

  A resin material such as rubber can be used for the elastic member 98. It is possible to appropriately select from resin materials or the like generally used for buffer materials or the like.

  Since the support plate 90 is installed on the placement portion 30, it is possible to fix the support plate 90 at a position relatively close to the place where the cargo c is placed (see FIG. 9). . Since the rack 10 is supported and fixed at a portion close to the position of the center of gravity, the function of preventing the rack 10 from falling or moving can be more effectively exhibited.

  Support plates 90 are installed around the four corners of the placement surface 31 (see FIG. 2). The installation position of the support plate 90 is not particularly limited, but by applying a structure that protrudes from the four corners of the placement surface 31 and presses it, an equal pressing force is applied to the inner wall side surface 221 of the container 200 from both sides. Is possible. It is possible to effectively prevent the rack 10 from being displaced after being fixed.

  The pressing member 110 includes a pressing bolt 111 that is fastened so as to extend toward the inner wall side surface 221 of the container 200, and a pressing nut 113 for attaching the pressing bolt 111 to the second plate 132. (See FIG. 5B).

  By increasing or decreasing the tightening amount of the pressing bolt 111, the amount by which the support plate 90 projects can be adjusted.

  The rack 10 is provided with a slide mechanism 130 that holds the support plate 90 slidably in the length direction of the container 200 (see FIGS. 5A and 5B).

  The slide mechanism 130 includes a first plate 131 disposed in the groove 45 of the steel material 41, a second plate 132 disposed on the back surface side of the groove 45 of the steel material 41 so as to be paired with the first plate 131, and a steel material. 41 has a slide hole 133 and a slide guide hole 135 provided in 41.

  The first plate 131 and the second plate 132 are connected using a fixing bolt 137 and a slide guide bolt 139. A first nut 141 for fastening the fixing bolt 137 and a second nut 142 for fastening the slide guide bolt 139 are attached to the first plate 131 by welding.

  The fixing bolt 137 has a screw portion disposed on the first plate 131 side through the slide hole 133 from the second plate 132 side. A first nut 141 provided on the first plate 131 is fastened to a thread portion of the fixing bolt 137.

  By adjusting the tightening amount of the fixing bolt 137 and the first nut 141, the fixing force of the first plate 131 and the second plate 132 with respect to the steel material 41 can be adjusted. The sliding movement of the first plate 131 and the second plate 132 is performed in a state where tightening by the first nut 141 is weakened. When the slide movement is not performed, the first nut 141 is tightened to be firmly fixed.

  The slide guide bolt 139 has a screw portion disposed on the first plate 131 side through the slide guide hole 135 from the second plate 132 side. A second nut 142 is fastened to the thread portion of the slide guide bolt 139.

  The slide guide bolt 139 exhibits a function of guiding the slide movement so that the first plate 131 and the second plate 132 connected by the fixing bolt 137 move along the slide hole 133 and the slide guide hole 135. .

  The slide hole 133 and the slide guide hole 135 are formed as long holes extending in parallel with the length direction of the container 200 (indicated by an arrow aa ′ in FIG. 5). Therefore, the sliding movement of the first plate 131 and the second plate 132 is a sliding movement along the length direction of the container 200.

  Since the pressing nut 113 of the pressing member 110 is fixed to the second plate 132, the pressing member 110 and the support plate 90 slide in conjunction with the sliding movement of the first plate 131 and the second plate 132. The maximum amount of slide movement is determined according to the length of the slide hole 133 and the slide guide hole 135.

  The surface shape of the inner wall side surface 221 of the container 200 is a concave portion 223, a convex portion 224, and a surface shape having two inclined portions 225 positioned between the concave portion 223 and the convex portion 224 as a unit. (See FIG. 11). It is desirable that the maximum amount of sliding movement of the support plate 90 is smaller than the length of the one unit and that the support plate 90 can be pressed to an arbitrary position of the one unit. When the rack 10 is installed in the container 200, the support plate 90 can be pressed against any position of the concave portion 223, the convex portion 224, and the inclined portion 225 regardless of the arrangement position of the rack 10. Because. The support plate 90 shown in the figure is slidable about 230 mm at the maximum along the length direction of the container 200.

  In order to simplify the maintenance work and the assembly work, the fixing bolt 137 for fixing the first plate 131 and the second plate 132 and the pressing bolt 111 of the pressing member 110 have the same diameter. A bolt with a head is used.

  Next, the operation of the rack according to the embodiment will be described.

  With reference to FIG. 9, the rack 10 is carried into the storage space s of the container 200 from the carry-in / out opening provided in the container 200.

  When carrying in, the height of the leg part 50 of the rack 10 is adjusted according to the size of the cargo c and the height of the container 200. The height of the entire rack 10 is adjusted by a height adjusting mechanism 150 provided on the leg portion 50 (see FIGS. 4 and 7). Since the height of the rack 10 can be adjusted according to the size of the cargo c, cargos c having various shapes can be stacked.
