Description

本発明は、荷収納区画の左右両隔壁枠の内側に、当該荷収納区画の前後奥行き方向に長い左右一対の荷受け部材が水平に架設された荷保管用ラックの荷支持装置に関するものである。   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.

この種の荷保管用ラックにおいて、地震時にラックが荷収納区画の前後奥行き方向（荷出し入れ方向）に揺れることによって、保管中の荷が当該ラックの通路側（ラックに沿って設けられた入出庫用クレーンの走行通路のある側）へ荷受け部材上を滑動して落下する事故が発生している。このような事故を未然に防止する一つの手段として、各荷収納区画が備える左右一対の荷受け部材を免震構造とすることが考えられている。例えば特許文献１に記載されるように、この種の荷保管用ラックの荷支持装置における免震構造は、荷収納区画の左右両隔壁枠から連設された支持部材に対して各荷受け部材をその長さ方向（荷収納区画の前後奥行き方向）にスライド可能に支持し、荷受け部材をスライド可能領域内の定位置に付勢保持する付勢手段として、支持部材の横側方に荷受け部材長さ方向と平行向きのコイルバネを設けるものであった。
特許第３７２９３１６号公報（特開２０００−２２６１１１号公報） 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. As a biasing means for supporting the load receiving member slidably in its length direction (the front and rear depth direction of the load storage section) and biasing and holding the load receiving member at a fixed position in the slidable region, the length of the load receiving member is lateral to the support member. A coil spring parallel to the vertical direction was provided.
Japanese Patent No. 3729316 (Japanese Patent Laid-Open No. 2000-226111)

特許文献１に記載された従来の構成における免震構造では、荷受け部材の全長と同一長さのレール状の支持部材と荷受け部材側に軸支されたローラーとで荷受け部材を水平前後方向にスライド可能に支持する必要があり、荷支持装置全体が大型でコスト高になる問題点があった。特に付勢手段として、特許文献１に記載されるような荷受け部材と平行な水平向きのコイルバネを利用する付勢手段を採用したのでは、十分な揺れの減衰効果が得られないばかりでなく、更に部品点数が多くなり、荷支持装置全体がより大型でコスト高になるため、実用的ではない。   In the conventional seismic isolation structure described in Patent Document 1, the load receiving member is slid in the horizontal front-rear direction by a rail-like support member having the same length as the entire length of the load receiving member and a roller pivotally supported on the load receiving member side. There is a problem that the entire load supporting device is large and expensive. In particular, when the biasing means using a horizontal coil spring parallel to the load receiving member as described in Patent Document 1 is used as the biasing means, not only a sufficient vibration damping effect cannot be obtained, Furthermore, since the number of parts increases and the whole load supporting device becomes larger and expensive, it is not practical.

It is the structure fixed to the opposite side (link 9a in the embodiment) from the side to which is fixed .

上記構成の本発明を実施するについて、具体的には請求項２に記載のように、前記支持部材７と吊下用平行リンク９ａ，９ｂとを垂直な滑りプレート１６を介して互いに当接させるように構成することができる。   In carrying out the present invention with the above configuration, specifically, as described in claim 2, the support member 7 and the suspension parallel links 9 a and 9 b are brought into contact with each other via a vertical sliding plate 16. It can be constituted as follows.

又、請求項３に記載のように、前記付勢ユニット１１Ａの角柱状の水平支点軸１２は支持部材７から水平横向きに固定突設して前記リンク９ａを貫通させ、前記保持用筒状体１５は前記リンク９ａの支持部材７のある側とは反対側に固定突設することができる。この場合、請求項４に記載のように、前記リンク９ａは、当該リンク９ａの揺動方向に平坦な垂直板材から構成し、当該リンク９ａと荷受け部材３とを軸支する水平支点軸１３は、前記リンク９ａから固着突設した丸パイプ材１３ａから構成し、この丸パイプ材１３ａの先端部に荷受け部材３を相対回転自在に支承することができる。更に、請求項５に記載のように、前記荷受け部材３は、前記隔壁枠２のある側が開放したコ形材から構成し、この荷受け部材３と前記リンク９ａとの軸支位置には、前記水平支点軸１３の丸パイプ材１３ａの先端部が相対回転自在に貫通する角パイプ材１７を荷受け部材３の内側空間に嵌合固定し、当該角パイプ材１７からの前記丸パイプ材１３ａの抜け止め具１７ｅを設けることができる。 According to a third aspect of the present invention, the prismatic horizontal fulcrum shaft 12 of the urging unit 11A is fixedly projected horizontally from the support member 7 so as to penetrate the link 9a, and the holding cylindrical body. 15 can be fixedly provided on the side of the link 9a opposite to the side where the support member 7 is located. In this case, as described in claim 4 , the link 9 a is formed of a vertical plate that is flat in the swinging direction of the link 9 a, and a horizontal fulcrum shaft 13 that pivotally supports the link 9 a and the load receiving member 3 is The round pipe member 13a fixedly projecting from the link 9a can be used, and the load receiving member 3 can be supported on the tip of the round pipe member 13a so as to be relatively rotatable. Further, as described in claim 5 , the load receiving member 3 is formed of a U-shaped material that is open on the side where the partition wall frame 2 is located, and the shaft support position between the load receiving member 3 and the link 9a includes A square pipe member 17 through which the tip of the round pipe member 13a of the horizontal fulcrum shaft 13 penetrates in a relatively rotatable manner is fitted and fixed in the inner space of the load receiving member 3, and the round pipe member 13a is removed from the square pipe member 17. A stop 17e can be provided.

又、請求項６に記載のように、荷収納区画１の左右両隔壁枠２には、前後一対の支柱材４ａ，４ｂを設け、各支柱材４ａ，４ｂは互いに対向する内側が開放した横断面形状に構成し、前記支持部材７は、前後両支柱材４ａ，４ｂの側壁板部４ｃに取り付けることができる。 Further, as described in claim 6 , the left and right partition wall frames 2 of the load storage compartment 1 are provided with a pair of front and rear support members 4a and 4b, and the support members 4a and 4b are crossed with the inner sides facing each other open. The supporting member 7 can be attached to the side wall plate portion 4c of the front and rear support members 4a and 4b.

本発明に係る荷保管用ラックの荷支持装置によれば、ラックが地震発生時に荷収納区画の前後奥行き方向（荷受け部材の長さ方向）に揺れ動いたとき、ラックと一体に前後に揺れ動く支持部材と荷を支持している荷受け部材との間に、当該荷受け部材を支持している前後一対の吊下用平行リンクの前後方向の平行揺動運動を伴って、付勢手段の付勢力に抗しての相対移動が生じ、荷を支持している荷受け部材がラックと一体に同一速度、同一振幅で前後方向に揺れ動くことがなくなる。従って、開放された通路側（前方）にラックが揺れ動いたときに荷受け部材及び当該荷受け部材上の荷が一体に前方に揺れ動くことにより、慣性で荷が荷受け部材上を通路側へ滑動し、場合によっては通路側へ落下してしまう恐れがなくなり、所期の免震効果が得られる。この支持部材と荷受け部材との間の前後方向の相対移動は、付勢手段の付勢力に抗しての吊下用平行リンクの平行揺動運動で実現しており、相対移動後は当該付勢手段の付勢力が荷受け部材を原点位置に自動復帰させるので、荷受け部材上で荷が滑動しない限り荷の位置が前後方向に不測に変動することはなく、安全に荷を継続保管することができる。   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 (the 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. The pair of front and rear suspension parallel links supporting the load receiving member is opposed to the urging force of the urging means with a parallel swinging motion in the front / rear direction between the load receiving member supporting the load and the load receiving member supporting the load. As a result, the load receiving member supporting the load does not swing in the front-rear direction at the same speed and the same amplitude as the rack. Therefore, when the rack swings to the opened passage side (forward), the load receiving member and the load on the load receiving member swing forward together, and the load slides on the load receiving member due to inertia. Depending on the situation, there is no risk of falling to the aisle side, and the desired seismic isolation effect can be obtained. The relative movement in the front-rear direction between the support member and the load receiving member is realized by a parallel swinging motion of the suspension parallel link against the urging force of the urging means. Since the urging force of the urging means automatically returns the load receiving member to the origin position, the load position will not change unexpectedly in the front-rear direction unless the load slides on the load receiving member, and the load can be safely stored continuously. it can.

而して、上記請求項１に記載の本発明の構成によれば、荷受け部材を荷収納区画の前後奥行き方向に移動可能に支持する手段として、垂直面に沿って前後方向に揺動する前後一対の吊下用平行リンクを利用したので、従来のような荷受け部材と同一長さのレール状の支持部材のような大型の部品やこの支持部材上に荷受け部材を移動自在に支持する複数のローラーなどが不要になり、荷支持装置全体をシンプル且つ軽量に構成することができる。しかも付勢手段により荷受け部材を、前記吊下用平行リンクが垂直に垂下する定位置に付勢保持するように構成したので、単に荷受け部材を前後方向に揺動自在に吊り下げたものと比較して、荷受け部材（荷）の前後方向の揺れを速やかに減衰させて免震効果を高めることができる。勿論、水平に前後揺動する平行リンクで荷受け部材を支持する場合と比較して、リンクに作用する曲げ力がゼロか又は格段に小さく、大重量の荷を取り扱える荷支持装置としも容易に実施することができると共に、荷受け部材が前後揺動したときに当該荷受け部材上の荷と荷受け部材との間で相対摺動が生じないので、不要な磨耗を生じさせないで済む。
更に本発明の構成によれば、付勢手段を吊下よう平行リンクの水平支点軸部分に組み込むことができ、しかも当該水平支点軸部分に捩じりコイルバネを組み込んで付勢手段とする場合よりも粘弾性体の振動減衰効果が期待でき、更に吊下用平行リンクと支持部材又は荷受け部材との間にガスダンパーを介装する場合と比較して、荷支持装置全体をコンパクトに、そして安価に構成することができる。 Thus, according to the configuration of the present invention as set forth in claim 1, as a means for supporting the load receiving member so as to be movable in the front-rear depth direction of the load storage section, the front and rear rocking in the front-rear direction along the vertical plane. Since a pair of hanging parallel links is used, a large part such as a rail-like support member having the same length as the conventional load receiving member, or a plurality of load receiving members that are movably supported on the support member are supported. A roller or the like is not necessary, and the entire load supporting device can be configured to be simple and lightweight. Moreover, the load receiving member is configured to be biased and held by the biasing means at a fixed position where the suspension parallel link hangs vertically, so that the load receiving member is simply suspended swingably back and forth. Thus, the seismic isolation effect can be enhanced by quickly attenuating the shaking of the load receiving member (load) in the front-rear direction. Of course, compared to the case where the load receiving member is supported by a parallel link that swings back and forth horizontally, the load force acting on the link is zero or much smaller, and it can be easily implemented as a load support device that can handle heavy loads. In addition, when the load receiving member swings back and forth, relative sliding does not occur between the load on the load receiving member and the load receiving member, so that unnecessary wear does not occur.
Furthermore, according to the configuration of the present invention, the urging means can be incorporated into the horizontal fulcrum shaft portion of the parallel link so as to be suspended, and the torsion coil spring is incorporated into the horizontal fulcrum shaft portion to form the urging means. The vibration damping effect of the viscoelastic body can be expected, and the entire load support device is more compact and inexpensive compared to the case where a gas damper is interposed between the parallel link for suspension and the support member or load receiving member. Can be configured.

尚、吊下用平行リンクは、その上端部がリンク一側方の支持部材に軸支されると共に下端部がリンク他側方の荷受け部材に軸支されるので、荷受け部材に載置される荷の重量を受けて当該リンクには外向き（支持部材のある側）に曲げ力が働くのであるが、請求項２に記載の構成によれば、前記リンクに作用する外向きの曲げ力を滑りプレートを介して支持部材で受け止めさせることができる。従って、リンクを曲げ強度の大きな太い角パイプ材などで構成する必要がなく、コストダウンを図ることができる。   In addition, since the upper end part of the parallel link for suspension is pivotally supported by the support member on one side of the link and the lower end part is pivotally supported by the load receiving member on the other side of the link, it is placed on the load receiving member. In response to the weight of the load, a bending force acts outward (on the side where the support member is provided) on the link. According to the configuration of claim 2, the outward bending force acting on the link is increased. It can be received by the support member via the sliding plate. Therefore, it is not necessary to form the link with a thick square pipe material having a large bending strength, and the cost can be reduced.

又、請求項３に記載の構成によれば、付勢ユニットの構成がリンク外側の広い空間を利用して容易に構成することができると共に、リンクを支持部材に隣接させることができるので、請求項２に記載の構成を採用する場合に、薄い板材から成る滑りプレートを支持部材の側面又はリンクの側面に直付けすることができ、構造をシンプルにして安価に実施することができる。又、請求項４に記載の構成を採用した場合、リンクと荷受け部材とが水平横方向に大きく離れることになるが、請求項５に記載の構成によれば、当該リンクと荷受け部材との軸支構造を頑丈に構成することができ、しかも荷受け部材そのものは、軽量安価なコ形材で構成できる。 Further , according to the configuration of the third aspect , the configuration of the urging unit can be easily configured using a wide space outside the link, and the link can be adjacent to the support member. In the case of adopting the configuration described in item 2, the sliding plate made of a thin plate material can be directly attached to the side surface of the support member or the side surface of the link, and the structure can be simplified and implemented at low cost. In addition, when the configuration described in claim 4 is adopted, the link and the load receiving member are greatly separated in the horizontal lateral direction. According to the configuration described in claim 5 , the shaft between the link and the load receiving member is used. The support structure can be constructed robustly, and the load receiving member itself can be constructed of a light and inexpensive U-shaped material.

又、請求項６に記載の構成によれば、地震力（振幅）が大きく、支持部材に対する許容スライド領域内での荷受け部材の相対移動だけでは十分な免震効果が期待できないような場合でも、支持部材に吊下用平行リンクを介して吊り下げられている荷受け部材そのものを、ラックの隔壁枠を構成する支柱材の側壁板部の左右横方向の弾性変形を利用して、ラックに対して前後水平方向に相対移動させることにより、免震効果を補わせることができる。従って、付勢手段の付勢ユニットに使用される粘弾性体の小型化にも役立つ。
Further, according to the configuration of claim 6 , even when the seismic force (amplitude) is large and a sufficient seismic isolation effect cannot be expected only by relative movement of the load receiving member within the allowable slide region with respect to the support member, The load receiving member itself suspended from the support member via the suspension parallel link is attached to the rack by utilizing the elastic deformation in the lateral direction of the side wall plate portion of the column member constituting the partition wall frame of the rack. By making relative movement in the front-rear and horizontal directions, the seismic isolation effect can be supplemented. Therefore, the viscoelastic body used in the urging unit of the urging means is useful for downsizing.

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.

As shown in FIGS. 2 and 3, the front and rear strut members 4a and 4b of the partition wall frame 2 have a cross-sectional shape in which the inner sides facing each other open. Thus, as shown in FIG. 2C, a pair of front and rear support members 7 for supporting both front and rear end portions of the load receiving member 3 are externally fitted to the side wall plate portion 4c having a square cross section projecting sideways of the column members 4a and 4b. In this state, the pins 8 are locked at the same height. The front and rear end portions of the load receiving member 3 are connected to the vertical plate portion 7a facing the load storage compartment 1 of each support member 7 via the parallel suspension links 9a and 9b, and the front and rear depth direction (X direction) of the load storage compartment 1 The suspended parallel receiving links 9a and 9b are attached to the suspended parallel receiving links 9a and 9b by urging and holding the suspended load receiving members 3 at fixed positions where the suspended parallel links 9a and 9b hang vertically. Energizing units 11A and 11B constituting the energizing means 10 are provided side by side.

The suspension parallel links 9 a and 9 b are made of a vertical plate that is flat in the front-rear swing direction, and the upper end portion thereof is supported by the upper horizontal fulcrum shaft 12. The vertical plate portion 7 a of the member 7 is pivotally supported on the upper end portion, and the lower end portion is pivotally supported on the load receiving member 3 by the lower horizontal fulcrum shaft 13. The urging units 11A and 11B are configured using the upper horizontal fulcrum shaft 12 on the outer side of the suspension parallel links 9a and 9b (the side opposite to the side where the support member 7 is provided).

吊下用平行リンク９ａ，９ｂを支持部材７に軸支する上側水平支点軸１２は、支持部材７の垂直板部７ａに溶接などで固着された円柱軸部１２ａと、この円柱軸部１２ａの端面に２本の取付ボルト１２ｃで同心状に連結された、円柱軸部１２ａの周囲に張り出す太さの四角軸部１２ｂとから構成され、板状の吊下用平行リンク９ａ，９ｂは、四角軸部１２ｂが連結される前の円柱軸部１２ａに相対回転自在に嵌合し、当該円柱軸部１２ａの周りで前後に揺動自在に吊り下げられる。付勢ユニット１１Ａ，１１Ｂは、前記上側水平支点軸１２の四角軸部１２ｂと、この四角軸部１２ｂに相対回転不能に外嵌する四角筒状の粘弾性体１４と、この粘弾性体１４に相対回転不能に外嵌する四角筒状の保持用筒状体１５とから構成されたもので、保持用筒状体１５は、その外端に蓋板１５ａが溶接などで固着されると共に、内端には外側にのみ張り出す取付板部１５ｂが溶接などで連設され、当該保持用筒状体１５に粘弾性体１４を嵌め込んだ状態で、当該粘弾性体１４の中央角孔に上側水平支点軸１２の四角軸部１２ｂが嵌まり込むように吊下用平行リンク９ａ，９ｂの外側に当て付け、取付板部１５ｂを複数本の取付ボルト１５ｃで吊下用平行リンク９ａ，９ｂに固定している。   The upper horizontal fulcrum shaft 12 that pivotally supports the suspension parallel links 9a and 9b on the support member 7 includes a cylindrical shaft portion 12a fixed to the vertical plate portion 7a of the support member 7 by welding or the like, and the cylindrical shaft portion 12a. The plate-like suspension parallel links 9a and 9b are composed of a square shaft portion 12b having a thickness projecting around the cylindrical shaft portion 12a concentrically connected to the end surface by two mounting bolts 12c. The cylinder shaft portion 12a is connected to the cylindrical shaft portion 12a before being connected to the square shaft portion 12b so as to be rotatable relative to the cylindrical shaft portion 12b, and is suspended swingably back and forth around the cylindrical shaft portion 12a. The urging units 11A and 11B include a rectangular shaft portion 12b of the upper horizontal fulcrum shaft 12, a rectangular tube-like viscoelastic body 14 fitted on the rectangular shaft portion 12b so as not to be relatively rotatable, and the viscoelastic body 14. The holding cylindrical body 15 has a rectangular cylindrical shape that is fitted so as to be relatively non-rotatable. The holding cylindrical body 15 has a cover plate 15a fixed to the outer end thereof by welding or the like, A mounting plate portion 15b that protrudes only outward is connected to the end by welding or the like, and the viscoelastic body 14 is fitted into the holding cylindrical body 15, and the upper side of the central square hole of the viscoelastic body 14 It is applied to the outside of the suspension parallel links 9a, 9b so that the square shaft portion 12b of the horizontal fulcrum shaft 12 is fitted, and the mounting plate portion 15b is attached to the suspension parallel links 9a, 9b with a plurality of attachment bolts 15c. It is fixed.

而して、吊下用平行リンク９ａ，９ｂが上側水平支点軸１２から真下に垂下する姿勢にあるとき、上側水平支点軸１２の四角軸部１２ｂの各垂直外側面と四角筒状の保持用筒状体１５の各垂直内側面とが互いに平行となるように構成されており、従って、粘弾性体１４周方向の応力が作用していない初期状態では、吊下用平行リンク９ａ，９ｂが上側水平支点軸１２から真下に垂下する姿勢に保持されると共に、荷受け部材３が荷収納区画１の前後奥行き方向（Ｘ方向）の揺動領域の中央定位置に保持される。   Thus, when the suspension parallel links 9a, 9b are in a posture to hang down from the upper horizontal fulcrum shaft 12, each vertical outer surface of the rectangular shaft portion 12b of the upper horizontal fulcrum shaft 12 and the rectangular cylindrical holding The vertical inner side surfaces of the cylindrical body 15 are configured to be parallel to each other. Therefore, in the initial state where the stress in the circumferential direction of the viscoelastic body 14 is not applied, the suspension parallel links 9a and 9b are While being held in a posture that hangs down directly from the upper horizontal fulcrum shaft 12, the load receiving member 3 is held at the center fixed position of the swing region in the front-rear depth direction (X direction) of the load storage section 1.

上側水平支点軸１２の円柱軸部１２ａは板状の吊下用平行リンク９ａ，９ｂの板厚よりも軸方向長さが適当に長いもので、吊下用平行リンク９ａ，９ｂを上側水平支点軸１２の四角軸部１２ｂの内端に隣接させるように配置したとき、当該吊下用平行リンク９ａ，９ｂと支持部材７の垂直板部７ａとの間に形成される空間を埋める厚さの、摩擦抵抗の小さな素材から成る滑りプレート１６が、吊下用平行リンク９ａ，９ｂの下半部の支持部材７に対面する側に、複数本の取付ネジ１６ａと吊下用平行リンク９ａ，９ｂ側に設けられたネジ孔とにより取り付けられている。従って、吊下用平行リンク９ａ，９ｂは、支持部材７の垂直板部７ａと平行な垂直姿勢を保って上側水平支点軸１２（円柱軸部１２ａ）の周りで前後に揺動することができ、このとき滑りプレート１６が支持部材７の垂直板部７ａに摺接する。従って、滑りプレート１６を取り付ける取付ネジ１６ａは、当該滑りプレート１６の滑り面から突出しない皿ネジが使用されている。   The cylindrical shaft portion 12a of the upper horizontal fulcrum shaft 12 has an axial length appropriately longer than the plate thickness of the plate-like suspension parallel links 9a, 9b, and the suspension parallel links 9a, 9b are connected to the upper horizontal fulcrum shaft. When arranged so as to be adjacent to the inner end of the 12 rectangular shaft portions 12b, the thickness of the space formed between the suspension parallel links 9a, 9b and the vertical plate portion 7a of the support member 7 is filled, A plurality of mounting screws 16a and the suspension parallel links 9a and 9b side are provided on the side where the sliding plate 16 made of a material having small frictional resistance faces the support member 7 in the lower half of the suspension parallel links 9a and 9b. It is attached with the screw hole provided in. Accordingly, the suspension parallel links 9a and 9b can swing back and forth around the upper horizontal fulcrum shaft 12 (cylindrical shaft portion 12a) while maintaining a vertical posture parallel to the vertical plate portion 7a of the support member 7. At this time, the sliding plate 16 is in sliding contact with the vertical plate portion 7 a of the support member 7. Therefore, the mounting screw 16a for attaching the sliding plate 16 is a countersunk screw that does not protrude from the sliding surface of the sliding plate 16.

下側水平支点軸１３は、吊下用平行リンク９ａ，９ｂの支持部材７のある側とは反対側に溶接などで固着突設された丸パイプ材１３ａから構成され、吊下用平行リンク９ａ，９ｂに対する丸パイプ材１３ａの取付強度と丸パイプ材１３ａ自体の曲げ強度とを高めるために、当該丸パイプ材１３ａと吊下用平行リンク９ａ，９ｂとの間に上下一対の補強板１３ｂ，１３ｃが溶接などで固着されている。   The lower horizontal fulcrum shaft 13 is composed of a round pipe material 13a fixedly projected by welding or the like on the side opposite to the side where the support member 7 of the suspension parallel links 9a, 9b is provided, and the suspension parallel link 9a. In order to increase the mounting strength of the round pipe member 13a to the round pipe member 13a and the bending strength of the round pipe member 13a itself, a pair of upper and lower reinforcing plates 13b, between the round pipe member 13a and the suspension parallel links 9a, 9b, 13c is fixed by welding or the like.

一方、荷受け部材３は、支持部材７のある側が開放したコ形材（溝形鋼）から成るもので、その前後両端部には、上下両側面が荷受け部材３の上下両側板部３ａ，３ｂの内側面に隣接するサイズの角パイプ材１７が嵌合されると共に、荷受け部材３の上側板部３ａと角パイプ材１７とを複数本の取付ネジ１７ａにより互いに結合している。この取付ネジ１７ａには、荷受け部材３の上面（上側板部３ａの上側荷支持面）から突出しない皿ネジが使用されている。而して、前記角パイプ材１７の左右両側板部１７ｂ，１７ｃには、吊下用平行リンク９ａ，９ｂから突設された下側水平支点軸１３の丸パイプ材１３ａが相対回転自在に貫通する貫通孔１７ｄが設けられ、この貫通孔１７ｄに前記丸パイプ材１３ａを挿通し、当該丸パイプ材１３ａの抜け止めとして、角パイプ材１７の外側の側板部１７ｂの内側に隣接して丸パイプ材１３ａに割りピンなどの抜け止め具１７ｅが装着されている。   On the other hand, the load receiving member 3 is made of a U-shaped material (grooved steel) that is open on the side where the support member 7 is provided, and both upper and lower side surfaces of the load receiving member 3 are upper and lower side plates 3a and 3b. A square pipe member 17 having a size adjacent to the inner surface of the load receiving member 3 is fitted, and the upper plate portion 3a of the load receiving member 3 and the square pipe member 17 are coupled to each other by a plurality of mounting screws 17a. The mounting screw 17a is a countersunk screw that does not protrude from the upper surface of the load receiving member 3 (the upper load supporting surface of the upper plate portion 3a). Thus, the round pipe material 13a of the lower horizontal fulcrum shaft 13 projecting from the suspension parallel links 9a, 9b penetrates the left and right side plate portions 17b, 17c of the square pipe material 17 in a relatively rotatable manner. A through hole 17d is formed, and the round pipe member 13a is inserted into the through hole 17d so as to prevent the round pipe member 13a from coming off. The round pipe is adjacent to the inside of the side plate portion 17b outside the square pipe member 17. A retaining member 17e such as a split pin is attached to the material 13a.

以上の構成の荷支持装置において、荷が左右一対の荷受け部材３上に跨がって載置されたとき、荷受け部材３側の荷重は、角パイプ材１７、下側水平支点軸１３（丸パイプ材１３ａ）、吊下用平行リンク９ａ，９ｂ、及び上側水平支点軸１２の円柱軸部１２ａを介して支持部材７で受け止められる。而して、各荷受け部材３を前後方向に動かすように外力を作用させたときは、前後一対の吊下用平行リンク９ａ，９ｂが荷受け部材３の運動方向に前後平行揺動するのを伴って荷受け部材３が前後方向に平行運動することになるが、このとき、前後２つの付勢ユニット１１Ａ，１１Ｂにおいて、支持部材７に固定されている上側水平支点軸１２の四角軸部１２ｂに対して、前後平行揺動する吊下用平行リンク９ａ，９ｂに固定されている保持用筒状体１５が相対的に回転し、内周面が上側水平支点軸１２の四角軸部１２ｂに固定状態で且つ外周面が保持用筒状体１５に固定状態の粘弾性体１４に周方向の捩じり変形が生じる。換言すれば、荷受け部材３と支持部材７との間の前後方向の相対移動は、前後２つの付勢ユニット１１Ａ，１１Ｂの付勢力、即ち、粘弾性体１４の周方向の捩じり弾性に抗して行われる。   In the load supporting device having the above-described configuration, when the load is placed across the pair of left and right load receiving members 3, the load on the load receiving member 3 side is the square pipe material 17, the lower horizontal fulcrum shaft 13 (round The pipe member 13 a), the suspension parallel links 9 a and 9 b, and the cylindrical shaft portion 12 a of the upper horizontal fulcrum shaft 12 are received by the support member 7. Thus, when an external force is applied so as to move each load receiving member 3 in the front-rear direction, the pair of front and rear suspension parallel links 9a, 9b are accompanied by a back-and-forth parallel swing in the movement direction of the load receiving member 3. Thus, the load receiving member 3 moves in parallel in the front-rear direction. At this time, in the two front and rear urging units 11A and 11B, with respect to the square shaft portion 12b of the upper horizontal fulcrum shaft 12 fixed to the support member 7. Thus, the holding cylindrical body 15 fixed to the suspension parallel links 9a and 9b that swing back and forth in parallel is relatively rotated, and the inner peripheral surface is fixed to the square shaft portion 12b of the upper horizontal fulcrum shaft 12. In addition, circumferential torsional deformation occurs in the viscoelastic body 14 whose outer peripheral surface is fixed to the holding cylindrical body 15. In other words, the relative movement in the front-rear direction between the load receiving member 3 and the support member 7 is caused by the urging force of the two urging units 11A and 11B, that is, the torsional elasticity of the viscoelastic body 14 in the circumferential direction. Done against.

従って、地震などによりラックが荷収納区画１の前後奥行き方向（Ｘ方向）に揺れ動いたとき、荷を支持している荷受け部材３に対してラックと一体の支持部材７が、付勢ユニット１１Ａ，１１Ｂの粘弾性体１４の周方向の捩じり弾性に抗する吊下用平行リンク９ａ，９ｂの前後揺動運動を伴って同方向に揺動し、荷を支持している荷受け部材３と支持部材７との間で前後方向の相対移動が生じ、荷受け部材３上の荷は殆ど揺れ動かないか又は、支持部材７の揺れよりも遅れて小さな振幅で揺れ動くことになり、揺れの速度や振幅が想定範囲内であれば所期の免震効果が得られる。   Therefore, when the rack swings in the front-rear depth direction (X direction) of the load storage section 1 due to an earthquake or the like, the support member 7 integrated with the rack is supported by the biasing unit 11A, the load receiving member 3 supporting the load. A load receiving member 3 that supports the load by swinging in the same direction along with the back and forth swing motion of the suspension parallel links 9a and 9b that resist the torsional elasticity in the circumferential direction of the viscoelastic body 14 of 11B; A relative movement in the front-rear direction occurs between the support member 7 and the load on the load receiving member 3 hardly swings or swings with a small amplitude later than the swing of the support member 7. If the amplitude is within the expected range, the desired seismic isolation effect can be obtained.

又、上記実施形態では、支持部材７を支持している隔壁枠２の前後一対の支柱材４ａ，４ｂが横断面形状が開放断面であって、図２Ｃに示すように、支持部材７を取り付けている支柱材４ａ，４ｂの横向きに突出する横断面角形の側壁板部４ｃが内外水平方向に弾性変形できるものであるから、この支柱材４ａ，４ｂの横断面角形の側壁板部４ｃの内外水平方向の弾性変形を伴う方向であれば、支持部材７と隔壁枠２との間の水平方向の相対移動がある程度許容されている。従って、地震などによるラック（隔壁枠２）の揺れ方向によっては、支持部材７と荷受け部材３との間の水平前後方向の相対移動に加えて、支持部材７と隔壁枠２との間の水平方向の相対移動が、荷受け部材３で支持されている荷に対する免震効果を高めることにもなる。   In the above embodiment, the pair of front and rear support columns 4a and 4b of the partition wall frame 2 supporting the support member 7 has an open cross section, and the support member 7 is attached as shown in FIG. 2C. Since the side wall plate portion 4c having a square cross section projecting sideways of the supporting column members 4a and 4b can be elastically deformed in the horizontal direction inside and outside, the inside and outside of the side wall plate portion 4c having a square cross section shape of the column materials 4a and 4b. If the direction is accompanied by elastic deformation in the horizontal direction, the relative movement in the horizontal direction between the support member 7 and the partition frame 2 is allowed to some extent. Therefore, depending on the swing direction of the rack (partition wall frame 2) due to an earthquake or the like, the horizontal movement between the support member 7 and the partition wall frame 2 in addition to the relative movement in the horizontal front-rear direction between the support member 7 and the load receiving member 3 is possible. The relative movement in the direction also increases the seismic isolation effect for the load supported by the load receiving member 3.

付勢ユニット１１Ａ，１１Ｂの粘弾性体１４は、その周方向の捩じり弾性復元力で吊下用平行リンク９ａ，９ｂを真下に垂下する初期姿勢に自動復帰させるように作用しているので、ラックの揺れが収まったときには、当該粘弾性体１４の周方向の捩じり弾性復元力で荷受け部材３は所期の定位置に自動的に戻される。   Since the viscoelastic body 14 of the urging units 11A and 11B acts so as to automatically return the suspension parallel links 9a and 9b to the initial position depending on the torsional elastic restoring force in the circumferential direction. When the swing of the rack is settled, the load receiving member 3 is automatically returned to the intended fixed position by the torsional elastic restoring force in the circumferential direction of the viscoelastic body 14.

又、上記構成では、吊下用平行リンク９ａ，９ｂと上側水平支点軸１２との嵌合部と、当該吊下用平行リンク９ａ，９ｂから左右横方向に突出した下側水平支点軸１３と荷受け部材３との嵌合部とが、左右水平方向に大きく離れていることにより、板状の吊下用平行リンク９ａ，９ｂには、その下半部が支持部材７側に接近する方向の曲げ力を受けることになるが、この曲げ力は、当該吊下用平行リンク９ａ，９ｂに取り付けられた滑りプレート１６を介して支持部材７の垂直板部７ａで受け止められ、吊下用平行リンク９ａ，９ｂの変形は防止される。一方この構成では、吊下用平行リンク９ａ，９ｂの前後揺動は、滑りプレート１６と支持部材７の垂直板部７ａとの摺接を伴って行われるが、一方の摺接面が滑りプレート１６の表面であるから、吊下用平行リンク９ａ，９ｂの前後揺動時の摩擦抵抗は、当該滑りプレート１６の材質により小さくすることができる。勿論、滑りプレート１６は、支持部材７の垂直板部７ａ側に取り付けても良いし、両方に取り付けて滑りプレート１６どうしが互いに摺接するように構成しても良い。   Further, in the above configuration, the fitting portion between the suspension parallel links 9a and 9b and the upper horizontal fulcrum shaft 12, and the lower horizontal fulcrum shaft 13 protruding in the lateral direction from the suspension parallel links 9a and 9b, Since the fitting portion with the load receiving member 3 is greatly separated in the horizontal direction, the lower half of the plate-like suspension parallel links 9a, 9b approaches the support member 7 side. The bending force is received by the vertical plate portion 7a of the support member 7 via the sliding plate 16 attached to the suspension parallel links 9a and 9b, and the suspension parallel links. The deformation of 9a and 9b is prevented. On the other hand, in this configuration, the swinging parallel links 9a, 9b swing back and forth with sliding contact between the sliding plate 16 and the vertical plate portion 7a of the support member 7, but one sliding contact surface is the sliding plate. 16, the frictional resistance when the suspended parallel links 9 a and 9 b swing back and forth can be reduced by the material of the sliding plate 16. Of course, the sliding plate 16 may be attached to the vertical plate portion 7a side of the support member 7, or may be attached to both so that the sliding plates 16 are in sliding contact with each other.

尚、付勢ユニット１１Ａ，１１Ｂの介装位置は上記実施形態で示した位置に限定されない。例えば、上記実施形態のように、付勢ユニット１１Ａ，１１Ｂを吊下用平行リンク９ａ，９ｂと支持部材７との間に介装する場合でも、上側水平支点軸１２を吊下用平行リンク９ａ，９ｂに固定するときは、保持用筒状体１５を支持部材７側に固定して付勢ユニット１１Ａ，１１Ｂを構成することもできる。又、付勢ユニット１１Ａ，１１Ｂを吊下用平行リンク９ａ，９ｂと荷受け部材３との間に介装することも可能である。例えば、図示のように下側水平支点軸１３が吊下用平行リンク９ａ，９ｂに固定されているときは、保持用筒状体１５を荷受け部材３側に固定して付勢ユニット１１Ａ，１１Ｂを構成することができるし、この逆に、下側水平支点軸１３が荷受け部材３に固定されるときは、保持用筒状体１５を吊下用平行リンク９ａ，９ｂ側に固定して付勢ユニット１１Ａ，１１Ｂを構成することも可能である。勿論、付勢力を高めるために、吊下用平行リンク９ａ，９ｂと支持部材７との間と吊下用平行リンク９ａ，９ｂと荷受け部材３との間との両方に付勢ユニット１１Ａ，１１Ｂを介装することもできる。更に、前後一対の吊下用平行リンク９ａ，９ｂの内、何れか一方にのみ、付勢ユニットを併設しても良い。   The interposition positions of the urging units 11A and 11B are not limited to the positions shown in the above embodiment. For example, even when the urging units 11A and 11B are interposed between the suspension parallel links 9a and 9b and the support member 7 as in the above embodiment, the upper horizontal fulcrum shaft 12 is attached to the suspension parallel link 9a. , 9b, the urging units 11A, 11B can be configured by fixing the holding cylindrical body 15 to the support member 7 side. Further, the urging units 11 </ b> A and 11 </ b> B can be interposed between the suspension parallel links 9 a and 9 b and the load receiving member 3. For example, when the lower horizontal fulcrum shaft 13 is fixed to the suspension parallel links 9a and 9b as shown in the drawing, the holding cylindrical body 15 is fixed to the load receiving member 3 side and the urging units 11A and 11B. Conversely, when the lower horizontal fulcrum shaft 13 is fixed to the load receiving member 3, the holding cylinder 15 is fixed to the suspension parallel links 9a and 9b. It is also possible to configure the force units 11A and 11B. Of course, in order to increase the urging force, the urging units 11A and 11B are provided both between the suspending parallel links 9a and 9b and the support member 7 and between the suspending parallel links 9a and 9b and the load receiving member 3. Can also be installed. Furthermore, an urging unit may be provided only on either one of the pair of front and rear suspension parallel links 9a and 9b.

又、上記実施形態では、荷受け部材３は、付勢手段１０で付勢保持される定位置（吊下用平行リンク９ａ，９ｂの揺動を伴う荷受け部材３の揺動可能領域内の定位置）から前後何れの方向にも揺動できるように構成したが、前記定位置から後方（ラックの入出庫用クレーンの走行通路のある側とは反対側）には揺動できないように構成することもできる。更に、左右一対の荷受け部材３は、入出庫用クレーンの荷移載用フォークなどによる荷の出し入れに影響しない箇所、例えば荷受け部材３の後端部や、前記荷移載用フォークの出退空間より下側で、荷受け部材３どうしを連結部材で互いに連結することも可能である。   Moreover, in the said embodiment, the load receiving member 3 is fixed position in the rockable | fluctuable area | region of the load receiving member 3 accompanying rocking | fluctuation of the parallel links 9a and 9b for suspension with the biasing means 10 biasing-maintaining. ) From the fixed position to the rear (the side opposite to the side where the traveling path of the rack loading / unloading crane is located). You can also. Further, the pair of left and right load receiving members 3 are located at locations that do not affect loading / unloading by the load transfer fork of the crane for loading and unloading, for example, the rear end portion of the load receiving member 3 and the space for moving the load transfer fork. On the lower side, the load receiving members 3 can be connected to each other by a connecting member.
