Description

  The present invention relates to a load support device for a load storage rack in which a pair of left and right load receiving members that are long in the front-rear depth direction of the load storage section are horizontally installed inside the left and right partition walls of the load storage section.

In this type of load storage rack, when the rack swings in the front / rear depth direction (unloading / unloading direction) of the load storage section, the load being stored can be placed on the aisle side of the rack (the loading / unloading provided along the rack). There is an accident that the load receiving member slides and falls to the side of the traveling crane. As one means for preventing such an accident, a pair of left and right load receiving members included in each load storage section is considered to have a seismic isolation structure. For example, as described in Patent Document 1, the seismic isolation structure in the load support device of this type of load storage rack is configured such that each load receiving member is attached to a support member provided continuously from both left and right partition walls of the load storage section. An urging means for supporting the load receiving member in a fixed position within the slidable region and supporting the load receiving member in a slidable direction in the length direction (the front and rear depth direction of the load storage section) is provided.
Japanese Patent No. 3729316 (Japanese Patent Laid-Open No. 2000-226111)

  In the seismic isolation structure in the conventional configuration described in Patent Document 1, since the biasing means including a coil spring is used, the effect of quickly attenuating the swing of the load (load receiving member) with respect to the rack (support member) is achieved. It was scarce and impractical.

  The object of the present invention is to provide a load support device for a load storage rack capable of solving the conventional problems as described above, and the load support device for a load storage rack according to claim 1. A pair of left and right support members 10 are installed inside the left and right bulkhead frames 2 of the load storage compartment 1, and the load receiving members 3 are fixed to both the support members 10 in the front-rear depth direction (X direction) of the load storage compartment 1. A load support device for a load storage rack that is supported so as to be movable back and forth within a range, and between the load receiving member 3 and the support member 10, the load receiving member 3 is biased to a fixed position within the forward and backward moving region. A gas damper 25 to be held is interposed, and the load receiving member 3 is configured to be movable forward from at least the fixed position against the biasing force of the gas damper 25. Before constructing the bulkhead frame 2 Pair of struts 4a, has a configuration which is arranged in the longitudinal direction between 4b.

  In carrying out the present invention having the above-described configuration, specifically, as described in claim 2, the load receiving member 3 is composed of a gate member having a lower open side, and the support member 10 is connected to the load receiving member 3 in a plan view. Support members 11a to 11d that are arranged in overlapping positions and that enter the inside of the load receiving member 3 and support the top plate portion 3a of the load receiving member 3 so as to be movable in the front-rear direction are supported on the support member 10 by the length of the support member. A columnar body that is disposed at a plurality of locations in the direction and is provided with a movement region regulating means 13 for the load receiving member 3 relative to the support member 10, and hangs down to the lateral position of the support member 10 on the side of the load receiving member 3 adjacent to the partition frame 2. 29, and the gas damper 25 can be interposed between the columnar body 29 on the load receiving member 3 side and the support member 10 at a position just beside the support member 10.

  Further, as described in claim 3, each of the supports 11a to 11d includes a bearing member 15 mounted on the support member 10 and horizontal shaft rollers 17a and 17b pivotally supported by the bearing member 15, and receives the load. The top plate portion 3a of the member 3 can be provided with strip-shaped rail plates 18a and 18b with which the horizontal axis rollers 17a and 17b abut. In this case, as described in claim 4, the support member 10 includes a pair of left and right vertical shaft rollers 19 a and 19 b adjacent to the left and right side plate portions 3 b and 3 c of the load receiving member 3, and the inner side of the load receiving member 3. The steady-prevention roller units 12a and 12b that are fitted into the support member can be disposed at a plurality of locations in the length direction of the support member.

  As a support tool, as described in claim 5, the flat support surface 36 parallel to the top plate portion 3a of the load receiving member 3 and the flat side surfaces 37a and 37b adjacent to the left and right side plate portions 3b and 3c of the load receiving member 3 are provided. It can also comprise from the block material 38 which has these.

  Further, as described in claim 6, the moving region restricting means 13 includes long holes 21 a and 21 b provided in the left and right side plate portions 3 b and 3 c of the load receiving member 3 along the length direction of the load receiving member. A horizontal shaft 22 that penetrates the long holes 21 a and 21 b and a bearing member 23 that supports both ends of the horizontal shaft 22 on the left and right outer sides of the load receiving member 3 and is attached to the support member 10 can be used.

  Furthermore, as described in claim 7, the pair of front and rear strut members 4a and 4b constituting the left and right partition wall frames 2 of the load storage section 1 have a cross-sectional shape with the inner sides facing each other open, and the support The member 10 can support both ends in the length direction on the arm members 7a and 7b attached to the side wall plate portions 4c of the front and rear support columns 4a and 4b.

  According to the load supporting device for a load storage rack according to the present invention, when the rack swings back and forth in the depth direction (length direction of the load receiving member) of the load storage section when an earthquake occurs, the support member swings back and forth integrally with the rack. And a load receiving member supporting the load, a relative movement in the front-rear direction occurs, and the load receiving member supporting the load does not swing in the front-rear direction at the same speed and with the same amplitude as the rack. For example, when the load receiving member is biased and held by the biasing force of the gas damper at the rear end position of the front and rear movement region with respect to the support member, the rack (support member) is forward (the passage in which the load storage section is open). When the rack (supporting member) swings backward, the load receiving member on which the load is loaded is subject to inertia. Since it tries to stay in the position, the load receiving member moves relatively forward against the urging force of the gas damper as viewed from the support member. In other words, the load on the load receiving member slides forward on the load receiving member due to inertia when the rack (supporting member) swings backward as in the case where the load receiving member is fixed on the support member. Since the load receiving member itself moves integrally with the load mounted on the load receiving member, the load receiving member itself moves forward relative to the support member, so that the load does not slide forward with respect to the load receiving member. Then, after the rack (support member) starts to swing backward, the load is loaded when the biasing force of the gas damper wins over the forward inertial force acting on the load receiving member carrying the load. The load receiving member is moved rearwardly on the support member by the biasing force of the gas damper, and returns to the original retreat limit position.

  By repeating the above action, when the rack swings in the longitudinal direction of the load storage section (the length direction of the load receiving member) when an earthquake occurs, the load on the load receiving member and the load receiving member swings forward integrally. Due to inertia, there is no risk that the load slides on the load receiving member to the passage side, and in some cases, drops to the passage side, and the desired seismic isolation effect is obtained. Of course, after the relative movement in the front-rear direction between the support member and the load receiving member, the urging force of the gas damper automatically returns the load receiving member to the origin position (retreat limit position), so that the load does not slide on the load receiving member. The position of the load does not change unexpectedly in the front-rear direction, and the load can be safely stored continuously.

  Thus, according to the configuration of the present invention described in claim 1, the load receiving member supported so as to be movable in the front-rear direction with respect to the support member is placed at a fixed position in the front-rear movement region, for example, after the front-rear movement region. Since the gas damper is used as the biasing means for biasing and holding at the end position, the load (load receiving member) sways quickly with respect to the rack (support member) as compared with the conventional configuration using a coil spring. A damping effect can be expected, and it can be put to practical use as a highly safe load supporting device. In addition, according to the configuration of the present invention, while using a long and large gas damper, the gas damper is arranged between the front and rear support members of the partition wall frame of the rack adjacent to the load receiving member in plan view. Since it is arranged in the front-rear direction, it is not necessary to increase the space between the bulkhead frames and the vertical space (height of the load storage section) of the load receiving member in order to use the gas damper, which can reduce the storage efficiency of the rack. Absent. Of course, there is no risk of damaging the gas damper by accidentally colliding a load or transfer device with the gas damper during loading / unloading work into the load storage compartment, and safely loading and unloading work without being aware of the gas damper. Yes.

  In addition, according to the structure of Claim 2, the whole support apparatus containing a cargo receiving member, a supporting member, and a gas damper can be comprised compactly. In this case, according to the configuration described in claim 3, the load receiving member itself can be smoothly moved back and forth with respect to the support member while the load receiving member itself is made of a relatively thin plate material, and the function of the gas damper can be achieved. Can be fully exhibited. Furthermore, according to the structure of Claim 4, the load receiving member which moves back and forth with respect to the support member is prevented from swinging in the lateral direction, and the load receiving member can be moved back and forth more smoothly with respect to the support member. . Of course, the support tool for supporting the load receiving member is not limited to the one using a horizontal axis roller, and when configured as in claim 5, an expensive and low durability horizontal axis roller is not used. At the same time, since the roller unit for preventing the lateral movement of the load receiving member is not necessary, the cost can be greatly reduced.

  Further, according to the configuration of the sixth aspect, not only can the forward / backward movement region of the load receiving member with respect to the support member be restricted within a predetermined range, but also inconvenience that the load receiving member is lifted with respect to the support member can be avoided. Can be further enhanced.

  Furthermore, according to the structure of Claim 7, it utilizes the elastic deformation of the side wall board part of the support | pillar material which comprises the partition wall frame of a rack for the horizontal deformation of the rack at the time of the occurrence of an earthquake. On the other hand, since the load receiving member carrying the load together with the support member can be moved relative to the rack in the lateral direction, the seismic isolation effect can be further enhanced.

  FIG. 1 shows a basic configuration of a rack to which the load supporting apparatus of the present invention can be applied. Reference numeral 1 denotes a load storage section arranged in a grid pattern in both the upper, lower, left and right directions, and adjacent loads in the left and right lateral directions. A partition frame 2 is erected vertically between the storage compartments 1, and the load storage compartments 1 adjacent to each other in the vertical direction are separated by a pair of left and right load receiving members 3.

  Each partition frame 2 has a lattice structure in which a pair of front and rear support members 4a and 4b are connected to each other by a connecting member 5. On the back side of the load storage compartment 1, the rear support members 4b of each partition frame 2 are On the front side of the load storage section 1, that is, on the traveling passage side of the loading / unloading crane that loads and unloads the load storage section 1, the load is stored in the load storage section 1. It is known that the front strut members 4a of the partition wall frames 2 are connected to each other by a horizontal connecting material (not shown) at a level that does not interfere with loading and unloading. The pair of left and right load receiving members 3 are rod-shaped members that are long in the loading / unloading direction of the load storage section 1, that is, the front-rear depth direction (X direction) of the load storage section 1, and the front and rear ends thereof are partition walls adjacent to the outside. It is supported by both front and rear support members 4a and 4b of the frame 2.

  Hereinafter, the first embodiment of the present invention will be described in detail. As shown in FIGS. 2 to 4, the front and rear strut members 4 a and 4 b of the partition wall frame 2 have a cross-sectional shape in which the inner sides facing each other open. The mounting member 8 to which the arm members 7a and 7b protruding laterally corresponding to the heights supporting the front and rear ends of the load receiving member 3 are fixed to the support members 4a and 4b as shown in FIG. 3B. The pin 9 engages with the side wall plate 4c having a square cross section projecting sideways. Thus, between the pair of front and rear arm members 7 a and 7 b, the front and rear end portions of the support member 10 positioned in parallel with the load receiving member 3 are attached at positions that overlap directly below the load receiving member 3.

  The detailed structure will be described with reference to FIGS. 2 to 6. As shown in detail in FIG. 5, the support member 10 has an outer side that is not adjacent to the top plate portion 10 a and the partition frame 2 of the top plate portion 10 a. It has an inverted L-shaped cross section having an outer vertical plate portion 10b depending from the side, and both front and rear ends of the top plate portion 10a are placed on the arm members 7a and 7b and attached with bolts and nuts 10c. As shown in detail in FIG. 5, the load receiving member 3 is formed of a gate material that is open on the lower side, and includes a top plate portion 3 a and left and right side plate portions 3 b and 3 c that are suspended from the left and right sides of the top plate portion 3 a. And has almost the same width as the support member 10.

  As shown in FIGS. 2 to 4, four support tools 11 a to 11 d and two steadying roller units 12 a and 12 b are provided on the upper side of the top plate portion 10 a of the support member 10 in the length direction. ing. The support tools 11a and 11b are arranged at both front and rear end positions of the support member top plate portion 10a, and the support tool 11c is sufficiently closer to the support tool 11b on the rear end side than the center position between the support tools 11a and 11b at both front and rear ends. The support tool 11d is arranged at a central position between the front end side support tool 11a and the rear end support tool 11c, and the steadying roller units 12a and 12b are arranged at the front end side support tool 11a and the rear end. It arrange | positions in the position adjacent to the intermediate support tool 11d side of the slip support tool 11c. In addition, between the load receiving member 3 and the support member 10, the length of the forward and backward movement region of the load receiving member 3 with respect to the support member 10 is regulated at a position between the intermediate support tool 11 d and the rear end support tool 11 c. A moving area regulating means 13 is provided.

  Each support tool 11a-11d has the same structure, and as shown in detail in FIG. 6, a pair of left and right bearings are mounted on the top plate portion 10a of the support member 10 with two front and rear bolt nuts 14. A U-shaped bearing member 15 having plate portions 15a and 15b, and left and right shafts that are concentrically supported by horizontal support shafts 16a and 16b on the outer sides of a pair of left and right bearing plate portions 15a and 15b of the bearing member 15, respectively. A pair of horizontal shaft rollers 17a and 17b is configured to freely move back and forth through the top plate portion 3a of the load receiving member 3 by the pair of left and right horizontal shaft rollers 17a and 17b while being fitted inside the load receiving member 3. To support. Note that two strip-like rail plates 18a and 18b are laid on the load receiving member top plate portion 3a at locations where the pair of left and right horizontal shaft rollers 17a and 17b abut. Note that one wide horizontal axis roller may be used instead of the pair of left and right horizontal axis rollers 17a and 17b, and one wide band rail plate is used instead of the two belt-like rail plates 18a and 18b. May be used. Of course, the load receiving member 3 itself can be made of a thick plate material, and the strip-shaped rail plate can be omitted.

  The steadying roller units 12a and 12b have the same structure. As shown in detail in FIG. 7, two vertical shaft rollers 19a and 19b are respectively provided on the top plate portion 10a of the support member 10 as roller support shafts. The vertical bolt rollers 19a and 19b are erected by dual-purpose bolts and nuts 20a and 20b, and are fitted inside the load receiving member 3 so that both vertical shaft rollers 19a and 19b are adjacent to the inner side surfaces of the left and right side plate portions 3b and 3c of the load receiving member 3. It is out.

  As shown in FIGS. 2 to 4 and 8, the movement region regulating means 13 is a pair of left and right elongated holes 21 a and 21 b provided in the left and right side plate portions 3 b and 3 c of the load receiving member 3 along the length direction. And a horizontal shaft 22 using one bolt and nut that penetrates both the long holes 21a and 21b in the lateral direction and a pair of left and right bearing plates 23a and 23b that support both ends of the horizontal shaft 22 of the load receiving member 3. The U-shaped bearing member 23 is provided on the top plate portion 10a of the support member 10 and is attached with two bolts and nuts 24. As shown in FIGS. Is in a fixed position (home position) overlapping with the support member 10, the horizontal shaft 22 is configured to be adjacent to the front ends of the long holes 21 a and 21 b. Accordingly, the load receiving member 3 is supported in a state in which it can move back and forth only within the range of the length of the long holes 21a and 21b in front of the fixed position.

  A gas damper 25 that biases and holds the load receiving member 3 in the fixed position is interposed between the load receiving member 3 and the support member 10. The gas damper 25 is also called a gas spring, and has a cylinder body 25a and a piston rod 25b extended from one end of the cylinder body 25a, and an external force exceeding a certain level causes the piston rod 25b to retract. The piston rod 25b is allowed to retract with respect to the cylinder body 25a when acting in the direction, and the piston rod 25b is extended with a built-in spring force when the external force stops working or becomes smaller. However, the speed of expansion and contraction movement of the piston rod 25b is regulated by the built-in gas pressure.

  The gas damper 25 is disposed in a front-rear direction, that is, in a direction parallel to the support member 10 at a position just beside the partition wall 2 of the support member 10, and the free end portion of the cylinder body 25a is shown in detail in FIG. As shown, the bolt nut 26 is provided on the outer side of the inner vertical plate piece 10d continuously provided downward from the inner side of the top plate portion 10a of the support member 10 (the side opposite to the side having the outer vertical plate portion 10b). As shown in detail in FIG. 10, the free end portion of the piston rod 25 b is pivoted on the gas damper mounting member 27 mounted on the vertical support shaft 28, and the upper end portion is on the side plate portion 3 b on the inner side of the load receiving member 3. It is supported by a vertical damper shaft 32 on a gas damper mounting member 31 that is fixed to a columnar body 29 using a grooved member that is fixed to a position just beside the support member 10 with a bolt nut 30. The gas damper mounting member 27 for mounting the free end portion of the cylinder body 25a has a structure in which the mounting position can be slightly adjusted in the front-rear direction by loosening the bolt and nut 26, and the gas damper mounting member 27 after the mounting position adjustment is An adjustment bolt nut 33 for receiving the gas damper mounting member 27 is attached to the angle member 34 on the inner vertical plate piece 10d on the support member 10 side so as not to be displaced forward by an external force acting in the compression direction on the gas damper 25. Is attached through.

  According to the above configuration, the load receiving member 3 is pressed rearward by the urging force of the gas damper 25, and the retreat limit position is regulated by the contact between the front ends of the long holes 21 a and 21 b of the moving region regulating means 13 and the horizontal shaft 22. That is, when a forward external force that overcomes the rearward urging force by the gas damper 25 is applied to the load receiving member 3 while being held in place, the load receiving member 3 is supported as shown in FIG. The member 10 can be slid forward. When the forward external force acting on the load receiving member 3 disappears, or when the forward external force is smaller than the backward biasing force by the gas damper 25, the load receiving member 3 moves backward on the support member 10 To automatically return to the original fixed position. The back-and-forth movement of the load receiving member 3 on the support member 10 is performed in a state where the lateral movement in the lateral direction is prevented by the steadying roller units 12a and 12b, and the horizontal axis rollers 17a and 11b of the respective support tools 11a to 11d. It is light and smooth with relative rolling of the strip-like rail plates 18a, 18b on 17b.

  Therefore, when the rack swings in the longitudinal depth direction (X direction) of the load storage section 1 due to an earthquake or the like, the support member 10 integrated with the rack swings in the same direction with respect to the load receiving member 3 supporting the load. However, relative movement in the front-rear direction occurs between the load receiving member 3 supporting the load and the support member 10, and the load mounted on the load receiving member 3 slides forward with respect to the load receiving member 3 due to inertia. Expected seismic isolation effect that avoids dangerous situations such as loss or sliding distance is shortened and the load falls from the load receiving member 3 to the front passage side (the open side of the load storage section 1). Is obtained. The load receiving member 3 slid forward with respect to the support member 10 returns to the original fixed position by the urging force of the gas damper 25, and the front ends of the long holes 21 a and 21 b of the moving region restricting means 13 and the horizontal shaft 22 It is conceivable that the load is slid backward on the load receiving member 3 due to inertia when the load receiving member 3 is restrained by the contact, but since the urging means is the gas damper 25, the load receiving member 3 is moved backward when the load receiving member 3 is moved backward. There is almost no shock when the speed is adjusted and the load receiving member 3 is stopped at a fixed position. Accordingly, it is not considered that the load slides vigorously backward on the load receiving member 3, and even if there is a slight backward slide, as described at the beginning, The side opposite to the passage side is closed by a connecting member 6 having a lattice structure, a wall plate material, or a wall of a building depending on the installation position of the rack (at least the load jumps out from the load storage section 1 to the rear). Since this is normal, there is no practical problem.

  In the above embodiment, the pair of front and rear support members 4a and 4b of the partition wall frame 2 supporting the front and rear ends of the support member 10 via the arm members 7a and 7b and the mounting member 8 have a cross-sectional shape. As shown in FIG. 3B, the side wall plate 4c having a square cross section projecting sideways of the column members 4a and 4b to which the mounting member 8 is attached can be elastically deformed in the inner and outer horizontal directions as shown in FIG. 3B. Therefore, the horizontal relative movement between the support member 10 and the partition frame 2 is to some extent as long as the side wall plate portion 4c having a square cross section of the column members 4a and 4b is in the direction accompanied by the elastic deformation in the inner and outer horizontal directions. Is allowed. Therefore, depending on the swinging direction of the rack (partition wall frame 2) due to an earthquake or the like, in addition to the horizontal front-rear direction relative movement between the support member 10 and the cargo receiving member 3, the left and right between the support member 10 and the partition frame 2 The relative movement in the horizontal direction also enhances the seismic isolation effect for the load supported by the load receiving member 3.

  In addition, according to the arrangement | sequence of the support tools 11a-11d of the said embodiment, as shown in FIG.2 and FIG.3, as usual, the load receiving member 3 is hold | maintained at the fixed position which is a rear-end position of the front-back movement area | region. In addition, a total of four places including the front and rear end portions and the middle two places are supported by the support tools 11a to 11d, and safely supports even a load whose center of gravity is biased near the front and rear ends of the load receiving member 3. Even if the load receiving member 3 moves forward as shown in FIG. 4 and the load receiving member 3 is disengaged forward from the rear end support 11b, the rear end of the load receiving member 3 can be used. Since the portion is supported by the rear-end support tool 11c, for example, compared with the case where it is supported by the support tool at a total of three positions, for example, the front and rear end positions of the load receiving member at a fixed position and one intermediate position, one rear Just add the end support 11c Stability when timber 3 is moved forward is remarkably improved.

  11 and 12 show another embodiment of a support provided between the load receiving member 3 and the support member 10. The support members 35a to 35c in this embodiment are the top plate portion of the support member 10 at a total of three positions: a front end position of the load receiving member 3 at a fixed position, a slightly forward position near the rear end, and an intermediate position between both positions. 10a, each support tool 35a-35c is a flat side surface adjacent to the left and right side plate portions 3b, 3c of the load receiving member 3 and a flat support surface 36 parallel to the top plate portion 3a of the load receiving member 3. 37a and 37b. In the illustrated example, the block member 38 is divided into a pair of left and right block pieces 38a and 38b, but the left and right side plate portions 3b and 3c of the load receiving member 3 are separated. It is also possible to constitute from one wide block material having a width slightly smaller than the inner width of the first block. This block member 38 (each block piece 38a, 38b) is preferably made of a material having a low frictional resistance such as hard synthetic resin, which is attached to the top plate portion 10a of the support member 10 by a plurality of bolts and nuts 39. is there. With the support tools 35a to 35c having such a configuration, the length of the flat support surface 36 is appropriately increased so that the load receiving member 3 is always stably supported even if it is disposed at three locations as shown in the figure. In addition, the load receiving member 3 can also serve as a steady rest in the lateral direction.

  In FIG. 11, the movement region regulating means 13 is arranged at two places in the longitudinal direction of the load receiving member 3. However, as a matter of course, at one place in the length direction of the load receiving member as in the previous embodiment. Can be configured.
