そして、補強板部２６ａ，２６ｂの第１辺と斜辺との角部には、たとえば２５ｍｍの長さ寸法を有する接続片部２６ｄが設けられている。接続片部２６ｄは、例えば３０ｍｍの幅寸法を有している。接続片部２６ｄは、補強板部２６ａ，２６ｂの第１辺に対して垂直に屈曲させて設けられている。すなわち、接続片部２６ｄは、補強板部２６ａ，２６ｂの端部を垂直に屈曲等させて一体的に設けられている。 And the connection piece part 26d which has a length dimension of 25 mm, for example is provided in the corner | angular part of the 1st edge | side and oblique side of reinforcement board part 26a, 26b. The connecting piece 26d has a width of 30 mm, for example. The connecting piece portion 26d is provided so as to be bent perpendicularly to the first sides of the reinforcing plate portions 26a and 26b. That is, the connection piece 26d is integrally provided by bending the end portions of the reinforcing plate portions 26a and 26b vertically.
さらに、補強板部２６ａは、接続片部２６ｄを屈曲片部２４ａ，２４ｂの内側面に接触させつつ、接続片部２６ｄに対向する補強板部２６ａ，２６ｂの第２辺を側板部２２ａ，２２ｂの外側面に接触させ、第１辺および第２辺のそれぞれを上板部２３ａ，２３ｂおよび側板部２２ａ，２２ｂそれぞれの幅方向に沿わせた状態とされて、これら屈曲片部２４ａ，２４ｂおよび側板部２２ａ，２２ｂに対して溶接等されて取り付けられている。さらに、補強板部２６ａ，２６ｂは、第１辺を上板部２３ａ，２３ｂの下面に接触させ、上板部２３ａ，２３ｂの長手方向の中心から等間隔、例えば８７．５ｍｍほど離間させた位置に２枚ずつ取り付けられている。さらに、補強板部２６ａ，２６ｂは、それぞれの接続片部２６ｄを相対する方向に向けた状態とされて取り付けられている。また、各補強板部２６ａ，２６ｂは、図２に示すように、底板部２１の底部補強材２１ｄに沿った位置、すなわち底板部２１の幅方向に沿って直線状に並ぶ位置に取り付けられている。 Further, the reinforcing plate portion 26a makes the second side of the reinforcing plate portions 26a and 26b facing the connecting piece portion 26d while the connecting piece portion 26d is in contact with the inner side surfaces of the bent piece portions 24a and 24b. The first side and the second side are in contact with the upper plate portions 23a, 23b and the side plate portions 22a, 22b, respectively, and the bent piece portions 24a, 24b, The side plate portions 22a and 22b are attached by welding or the like. Further, the reinforcing plate portions 26a and 26b are arranged such that the first sides are in contact with the lower surfaces of the upper plate portions 23a and 23b and are spaced apart from the longitudinal center of the upper plate portions 23a and 23b by an equal interval, for example, 87.5 mm. Two pieces are attached to each. Further, the reinforcing plate portions 26a and 26b are attached in a state in which the connection piece portions 26d are directed in the opposite directions. Further, as shown in FIG. 2, each of the reinforcing plate portions 26 a and 26 b is attached to a position along the bottom reinforcing member 21 d of the bottom plate portion 21, that is, a position aligned linearly along the width direction of the bottom plate portion 21. Yes.
ここで、これら補強板部２６ａ，２６ｂは、直線状に並ぶ底部補強材２１ｄに対して一体的に構成されている。すなわち、一対の補強板部２６ａ，２６ｂと底部補強材２１ｄとは、一枚の平板状の板材にて形成されている。具体的に、各補強板部２６ａ，２６ｂの第２辺の下部が底部補強材２１ｄの長手方向の端部に接続している。そして、この底部補強材２１ｄの長手方向の端部は、底板部２１から側板部２２ａ，２２ｂおよび補強底板材２１ｂの補強辺部２１ｃまでに亘って形成された切欠溝部２１ｅに嵌合させつつ、各側板部２２ａ，２２ｂの外側に突出し、この突出した部分が補強板部２６ａ，２６ｂの第２辺の下部に接続されている。したがって、一対の補強板部２６ａ，２６ｂと底部補強材２１ｄとにて一体的な補強部材２７を構成している。 Here, these reinforcement board parts 26a and 26b are comprised integrally with the bottom part reinforcement material 21d located in a line. That is, the pair of reinforcing plate portions 26a and 26b and the bottom reinforcing member 21d are formed of a single flat plate material. Specifically, the lower part of the second side of each reinforcing plate part 26a, 26b is connected to the end of the bottom reinforcing member 21d in the longitudinal direction. Then, the end portion in the longitudinal direction of the bottom reinforcing member 21d is fitted into a notch groove portion 21e formed from the bottom plate portion 21 to the side plate portions 22a and 22b and the reinforcing side portion 21c of the reinforcing bottom plate material 21b. The side plate portions 22a and 22b protrude to the outside, and the protruding portions are connected to lower portions of the second sides of the reinforcing plate portions 26a and 26b. Therefore, the pair of reinforcing plate portions 26a and 26b and the bottom reinforcing member 21d constitute an integral reinforcing member 27.
一方、各上板部２３ａ，２３ｂの下面には、複数、例えば計３台ずつキャスター３が、少なくとも荷台本体２の長手方向に沿って荷台本体２を移動可能とさせて取り付けられている。これらキャスター３は、各上板部２３ａ，２３ｂの長手方向の中心位置と、この中心位置から等間隔、例えば１９０ｍｍ離れた位置に取り付けられている。そして、各キャスター３は、転動輪３１と、この転動輪３１を周方向に回転可能に支持するキャスター本体３２と、このキャスター本体３２を水平方向に回転可能に支持する取付台３３とを備えている。取付台３３は、平面視略矩形平板状に形成され、各角部にねじ穴が形成され、取付台３３の上面を上板部２３ａ，２３ｂの下面に接触させた状態で、各ねじ穴にボルトを挿通させる等して上板部２３ａ，２３ｂの下面に取り付けられて固定されている。 On the other hand, a plurality of, for example, a total of three casters 3 are attached to the lower surfaces of the upper plate portions 23 a and 23 b so that the load carrier body 2 can move at least along the longitudinal direction of the load carrier body 2. The casters 3 are attached to the center positions of the upper plate portions 23a and 23b in the longitudinal direction and at positions spaced apart from the center positions at an equal interval, for example, 190 mm. Each caster 3 includes a rolling wheel 31, a caster body 32 that supports the rolling wheel 31 so as to be rotatable in the circumferential direction, and a mounting base 33 that supports the caster body 32 so as to be rotatable in the horizontal direction. Yes. The mounting base 33 is formed in a substantially rectangular flat plate shape in plan view, screw holes are formed at each corner, and the upper surface of the mounting base 33 is in contact with the lower surfaces of the upper plate parts 23a and 23b. The bolts are inserted and fixed to the lower surfaces of the upper plate portions 23a and 23b.
各取付台３３の下側には、この取付台３３の長手方向および幅方向、すなわち水平方向に沿って回転可能にキャスター本体３２がそれぞれ取り付けられている。よって、キャスター本体３２は、上板部２３ａ，２３ｂの下面に沿って、すなわち底板部２１の法線方向を中心軸として回転可能とされている。キャスター本体３２の下部には、タイヤである転動輪３１が回転可能に支持されて取り付けられている。転動輪３１は、荷台本体２を水平方向に移動可能にさせる。ここで、各転動輪３１は、この転動輪３１の外周面が、荷台本体２の底板部２１の下面よりも下方に、例えば２０ｍｍほど突出するように取り付けられている。 The caster main body 32 is attached to the lower side of each mounting base 33 so as to be rotatable along the longitudinal direction and the width direction of the mounting base 33, that is, the horizontal direction. Therefore, the caster main body 32 is rotatable along the lower surfaces of the upper plate portions 23a and 23b, that is, with the normal direction of the bottom plate portion 21 as the central axis. A rolling wheel 31 that is a tire is rotatably supported and attached to the lower part of the caster body 32. The rolling wheels 31 make the cargo bed body 2 movable in the horizontal direction. Here, each rolling wheel 31 is attached so that the outer peripheral surface of this rolling wheel 31 protrudes below the lower surface of the bottom plate portion 21 of the cargo bed body 2 by, for example, about 20 mm.
さらに、各キャスター３が取り付けられた状態で、荷台本体２の上板部２３ａ，２３ｂの上側面には、例えば１０ｍｍの厚さ寸法を有するゴムマット４が取り付けられている。このゴムマット４は、上板部２３ａ，２３ｂの長さ寸法に等しい、例えば５１０ｍｍの長さ寸法を有するとともに、上板部２３ａ，２３ｂの幅寸法に等しい、例えば１５０ｍｍの幅寸法を有する矩形平板状に形成され、上板部２３ａ，２３ｂの上面全体を覆っている。 Further, with each caster 3 attached, a rubber mat 4 having a thickness of 10 mm, for example, is attached to the upper side surfaces of the upper plate portions 23a, 23b of the cargo bed body 2. The rubber mat 4 has a rectangular flat plate shape having a length dimension equal to the length dimension of the upper plate portions 23a and 23b, for example, 510 mm, and a width dimension equal to the width dimension of the upper plate portions 23a and 23b, for example, 150 mm. And covers the entire upper surface of the upper plate portions 23a, 23b.
次に、上記一実施形態に係る荷台装置１の作用効果について説明する。 Next, the effect of the loading platform apparatus 1 which concerns on the said one Embodiment is demonstrated.
まず、例えばＨ鋼にて形成された構造物等の被搬送物の下端部（Ｈ鋼の部分）等が、荷台装置１の一対の側板部２２ａ，２２ｂ間の幅寸法より小さな幅寸法である場合には、荷台装置１の上板部２３ａ，２３ｂ上のゴムマット４上に被搬送物の下端部等を載置させずに、この被搬送物の下端部を荷台装置１の一対の側板部２２ａ，２２ｂ間に嵌合させて底板部２１の補強底板材２１ｂ上に載置させる。このとき、荷台装置１は、キャスター３の転動輪３１の外周面が底板部２１の下面よりも、２０ｍｍほど下方に突出しており、底板部２１の補強底板材２１ｂの上面までの厚さが、約２５ｍｍほどであるため、被搬送物の設置面から、約４５ｍｍほど搬送物を持ち上げるだけで、被搬送物を荷台装置１にて搬送可能な状態にできる。 First, for example, a lower end portion (H steel portion) of a transported object such as a structure formed of H steel has a width dimension smaller than a width dimension between the pair of side plate portions 22a and 22b of the loading platform apparatus 1. In this case, the lower end portion of the object to be conveyed is not placed on the rubber mat 4 on the upper plate portions 23 a and 23 b of the loading platform device 1, and the lower end portion of the conveyed object is used as a pair of side plate portions of the loading platform device 1. It fits between 22a and 22b, and is mounted on the reinforcement bottom board material 21b of the baseplate part 21. As shown in FIG. At this time, in the loading platform device 1, the outer peripheral surface of the rolling wheel 31 of the caster 3 protrudes downward by about 20 mm from the lower surface of the bottom plate portion 21, and the thickness of the bottom plate portion 21 to the upper surface of the reinforcing bottom plate material 21b is Since the distance is about 25 mm, the object to be conveyed can be conveyed by the loading platform device 1 by only lifting the object by about 45 mm from the installation surface of the object to be conveyed.
すなわち、被搬送物を余り持ち上げることなく、言い換えると被搬送物を余り高くすることなく、被搬送物を搬送することが可能となるため、例えば天井までの高さや、出入口の扉の高さが低い場合等の狭いスペースであっても、重量物である被搬送物を適切に搬送することができる。特に、複数のキャスター３の転動輪３１の外周面における、荷台本体２の底板部２１の下面からの下方への突出量を必要最小限にすることによって、被搬送物をより持ち上げずに搬送することが可能となるから、例えば、被搬送物の高さに略等しい狭いスペースであっても、被搬送物を適切に搬送することができる。また同時に、被搬送物を重心が低い位置で搬送できるので、搬送時における被搬送物の重心を安定でき、搬送時の被搬送物の転倒等をより適切に抑制することができる。 That is, since it is possible to transport the transported object without lifting the transported object too much, in other words, without increasing the transported object too much, for example, the height to the ceiling or the height of the door of the entrance / exit Even in a narrow space such as when it is low, it is possible to appropriately convey a heavy object to be conveyed. In particular, the object to be transported is transported without being lifted by minimizing the amount of protrusion of the outer peripheral surface of the rolling wheels 31 of the plurality of casters 3 downward from the bottom surface of the bottom plate portion 21 of the cargo bed body 2 to the necessary minimum. Therefore, for example, the object to be conveyed can be appropriately conveyed even in a narrow space substantially equal to the height of the object to be conveyed. At the same time, since the object to be conveyed can be conveyed at a position where the center of gravity is low, the center of gravity of the object to be conveyed at the time of conveyance can be stabilized, and the fall of the object to be conveyed at the time of conveyance can be more appropriately suppressed.
また、荷台装置１の上板部２３ａ，２３ｂ上のゴムマット４までの高さが、約１４５ｍｍであるため、被搬送物の下端部等が、荷台装置１の一対の側板部２２ａ，２２ｂ間の幅寸法より小さな幅寸法ではない場合であっても、被搬送物の設置面から、約１４５ｍｍほど被搬送物を持ち上げ、荷台装置１のゴムマット４上に載置させることによって、被搬送物を搬送可能にすることができる。よって、比較的高さが低いスペースであっても被搬送物を適切に搬送することができる。 Moreover, since the height to the rubber mat 4 on the upper plate portions 23a and 23b of the loading platform device 1 is about 145 mm, the lower end portion of the object to be conveyed is between the pair of side plate portions 22a and 22b of the loading platform device 1. Even if the width dimension is not smaller than the width dimension, the conveyed object is conveyed by lifting the conveyed object from the installation surface of the conveyed object by about 145 mm and placing it on the rubber mat 4 of the loading platform device 1. Can be possible. Accordingly, the object to be conveyed can be appropriately conveyed even in a space having a relatively low height.
また同時に、荷台装置１の荷台本体２の底板部２１から、一対の側板部２２ａ，２２ｂ、および一対の上板部２３ａ，２３ｂまでを、一枚の鉄板を屈曲等させて一体的に形成し、荷台本体２の一対の上板部２３ａ，２３ｂの下面に複数のキャスター３を取り付けた構成としている。この結果、荷台本体２の底板部２１上に下端部等を載置させた被搬送物の荷重に伴う応力が、荷台本体２の底板部２１から一対の側板部２２ａ，２２ｂおよび一対の上板部２３ａ，２３ｂまでに亘って分散するようになり、例えば、これら底板部２１、一対の側板部２２ａ，２２ｂ、および一対の上板部２３ａ，２３ｂを別部材にて形成して溶接等にて接続した構成の場合に比べ、比較的大きな重量を有する被搬送物であっても適切に搬送することができる。 At the same time, the bottom plate portion 21 of the loading platform body 2 of the loading platform device 1 to the pair of side plate portions 22a and 22b and the pair of upper plate portions 23a and 23b are integrally formed by bending one iron plate or the like. The plurality of casters 3 are attached to the lower surfaces of the pair of upper plate portions 23a, 23b of the cargo bed body 2. As a result, the stress accompanying the load of the object to be transported with the lower end or the like placed on the bottom plate portion 21 of the cargo bed main body 2 is changed from the bottom plate portion 21 of the cargo bed main body 2 to the pair of side plate portions 22a and 22b and the pair of top plates. For example, the bottom plate portion 21, the pair of side plate portions 22a, 22b, and the pair of upper plate portions 23a, 23b are formed by separate members and welded or the like. Compared with the connected configuration, even a transported object having a relatively large weight can be transported appropriately.
さらに、荷台装置１の荷台本体２の上板部２３ａ，２３ｂの下面に取付台３３を取り付け、この取付台３３の下側に水平方向に沿って回転可能にキャスター本体３２を取り付けた構成としている。よって、複数のキャスター３のキャスター本体３２が、荷台本体２の底板部２１の法線方向を中心軸として回転可能となり、荷台装置１が底板部２１に沿う方向、すなわち水平方向のいずれの方向にも移動可能となる。よって、荷台装置１の使い勝手を向上することができる。 Furthermore, the mounting base 33 is attached to the lower surface of the upper plate portions 23a and 23b of the base body 2 of the base device 1, and the caster body 32 is rotatably attached to the lower side of the mounting base 33 along the horizontal direction. . Therefore, the caster main bodies 32 of the plurality of casters 3 can be rotated with the normal direction of the bottom plate portion 21 of the loading platform main body 2 as the central axis, and the loading platform device 1 is in a direction along the bottom plate portion 21, that is, in any horizontal direction. Can also be moved. Therefore, the usability of the cargo bed apparatus 1 can be improved.
また、補強板部２６ａ，２６ｂの接続片部２６ｄを荷台本体２の屈曲片部２４ａ，２４ｂの内側面に接触させつつ、これら補強板部２６ａ，２６ｂの第２辺を荷台本体２の側板部２２ａ，２２ｂの外側面に接触させ、第１辺および第２辺のそれぞれを上板部２３ａ，２３ｂおよび側板部２２ａ，２２ｂそれぞれの幅方向に沿わせた状態として、これら屈曲片部２４ａ，２４ｂおよび側板部２２ａ，２２ｂに対して溶接等して取り付けた構成としている。さらに、これら補強板部２６ａ，２６ｂと底部補強材２１ｄとを一体にし、補強底板材２１ｂ上に係る負荷を底部補強材２１ｄから各補強板部２６ａ，２６ｂへ分散する構成としている。 Further, the connecting plate portion 26d of the reinforcing plate portions 26a and 26b is brought into contact with the inner side surfaces of the bent piece portions 24a and 24b of the loading platform body 2, and the second sides of these reinforcing plate portions 26a and 26b are set to the side plate portions of the loading platform body 2. The bent piece portions 24a and 24b are brought into contact with the outer surfaces of 22a and 22b, and the first side and the second side are arranged in the width direction of the upper plate portions 23a and 23b and the side plate portions 22a and 22b, respectively. And it is set as the structure attached by welding etc. with respect to the side-plate parts 22a and 22b. Further, the reinforcing plate portions 26a, 26b and the bottom reinforcing member 21d are integrated, and the load on the reinforcing bottom plate member 21b is distributed from the bottom reinforcing member 21d to the reinforcing plate portions 26a, 26b.
この結果、荷台本体２の上板部２３ａ，２３ｂの下面と側板部２２ａ，２２ｂの外側面との間、および底板部２１の上側のスペースを有効活用しつつ、荷台本体２の底板部２１または上板部２３ａ，２３ｂ上のゴムマット４上に被搬送物を載置させた場合に生じる被搬送物の荷重に伴う応力が、底板部２１と一対の側板部２２ａ，２２ｂとの間や、一対の側板部２２ａ，２２ｂと一対の上板部２３ａ，２３ｂとの間へ集中することをより適切に抑制することができる。よって、搬送する被搬送物の荷重に伴う応力の荷台本体２に対する分散をより適切にできるため、比較的大きな重量を有する被搬送物であってもより適切に搬送することができる。 As a result, while effectively utilizing the space between the lower surface of the upper plate portions 23a, 23b and the outer surface of the side plate portions 22a, 22b and the upper side of the bottom plate portion 21 of the load carrier body 2, the bottom plate portion 21 of the load carrier body 2 or The stress accompanying the load of the object to be conveyed that occurs when the object to be conveyed is placed on the rubber mat 4 on the upper plate parts 23a and 23b, the stress between the bottom plate part 21 and the pair of side plate parts 22a and 22b, Concentration between the side plate portions 22a and 22b and the pair of upper plate portions 23a and 23b can be more appropriately suppressed. Therefore, since the stress accompanying the load of the conveyed object to be conveyed can be more appropriately distributed to the bed body 2, even a conveyed object having a relatively large weight can be conveyed more appropriately.
また、これら補強板部２６ａ，２６ｂを平面視略直角三角形状とし、これら補強板部２６ａ，２６ｂが上板部２３ａ，２３ｂと側板部２２ａ，２２ｂとの間から余り外側に突出しない構造としている。このため、被搬送物を搬送する際に、補強板部２６ａ，２６ｂが周辺の障害物等に接触等することを少なくでき、被搬送物の搬送をより適切に行うことができる。 Further, the reinforcing plate portions 26a and 26b have a substantially right-angled triangular shape in plan view, and the reinforcing plate portions 26a and 26b do not protrude outwardly between the upper plate portions 23a and 23b and the side plate portions 22a and 22b. . For this reason, when conveying a to-be-conveyed object, it can reduce that the reinforcement board part 26a, 26b contacts a surrounding obstruction, etc., and can convey a to-be-conveyed object more appropriately.

本発明は、狭いスペースでも重量を有する被搬送物を搬送することができる荷台装置に関する。 The present invention relates to a cargo bed apparatus capable of transporting a transported object having a weight even in a narrow space.
従来、この種の荷台装置としては、例えば下記特許文献１に記載の構成の搬送具が知られている。本搬送具は、「荷役用パレット(５)を載置可能な載置台(２)と、載置台(２)を床面の上方位置に支持する支持脚(３)と、載置台(２)に連結した移送用ハンドル(４)とを備える。支持脚(３)は搬送用キャスター(７)を備える。載置台(２)はパレット収容部(10)を備える。パレット収容部(10)は、収容底部(11)と、この収容底部(11)の幅方向両端部に立設したパレット保持部(12)とを有する。」構成となっている（要約参照。）。 Conventionally, as this type of loading platform device, for example, a conveying tool having a configuration described in Patent Document 1 below is known. This transporting tool includes a “mounting table (2) on which a cargo handling pallet (5) can be mounted, a support leg (3) that supports the mounting table (2) at an upper position on the floor surface, and a mounting table (2). The support leg (3) includes a transfer caster (7), the mounting table (2) includes a pallet storage section (10), and the pallet storage section (10) includes a pallet storage section (10). And a pallet holding portion (12) erected on both ends in the width direction of the storage bottom (11) ”(see summary).
上記特許文献１に記載の搬送具は、載置台(２)を構成するパレット収容部(10)が、収容底部(11)と、この収容底部(11)の幅方向両端部に立設したパレット保持部(12)とで構成されており、パレット収容部(10)と支持脚(３)とが別体の板材にて形成されている。そして、支持脚(３)の下方に屈曲させた部分をパレット収容部(10)のパレット保持部(12)に接続した構成となっている。このため、パレット収容部(10)の収容底部(11)に荷役用パレット(５)を載置させて搬送する場合においては、支持脚(３)の下方に屈曲させた部分とパレット収容部(10)のパレット保持部(12)との接続箇所に、荷役用パレット(５)の荷重に伴う応力が集中してしまう。よって、大きな重量を有する荷役用パレット(５)を搬送する際に、支持脚(３)の下方に屈曲させた部分とパレット収容部(10)のパレット保持部(12)との接続箇所が損傷等してしまうおそれがあり、大きな重量を有する荷役用パレット(５)については、使用することができないという問題を有している。 The transport tool described in Patent Document 1 includes a pallet housing portion (10) that constitutes a mounting table (2), the pallet housing portion (10), and a pallet that is erected on both ends in the width direction of the housing bottom portion (11). The holding part (12) is comprised, and the pallet accommodating part (10) and the support leg (3) are formed with the board | plate material of a different body. And it has the structure which connected the part bent below the support leg (3) to the pallet holding | maintenance part (12) of a pallet accommodating part (10). For this reason, when the cargo handling pallet (5) is placed on the storage bottom (11) of the pallet storage part (10) and transported, the part bent below the support leg (3) and the pallet storage part ( The stress associated with the load on the cargo handling pallet (5) is concentrated at the connection part of the pallet holding part (12) of 10). Therefore, when the heavy handling pallet (5) is transported, the connection portion between the bent part of the support leg (3) and the pallet holding part (12) of the pallet receiving part (10) is damaged. There is a problem that the cargo handling pallet (5) having a large weight cannot be used.

一方、各上板部２３ａ，２３ｂの下面には、複数、例えば計３台ずつキャスター３が、少なくとも荷台本体２の長手方向に沿って荷台本体２を移動可能とさせて取り付けられている。これらキャスター３は、各上板部２３ａ，２３ｂの長手方向の中心位置と、この中心位置から等間隔、例えば１９０ｍｍ離れた位置に取り付けられている。そして、各キャスター３は、転動輪３１と、この転動輪３１を周方向に回転可能に支持するキャスター本体３２と、このキャスター本体３２を水平方向に回転可能に支持する取付台３３とを備えている。取付台３３は、平面視略矩形平板状に形成され、各角部にねじ穴が形成され、取付台３３の上面を上板部２３ａ，２３ｂの下面に接触させた状態で、各ねじ穴にボルトを挿通させる等して上板部２３ａ，２３ｂの下面に取り付けられて固定されている。 On the other hand, a plurality of, for example, a total of three casters 3 are attached to the lower surfaces of the upper plate portions 23 a and 23 b so that the load carrier body 2 can move at least along the longitudinal direction of the load carrier body 2. The casters 3 are attached to the center positions of the upper plate portions 23a and 23b in the longitudinal direction and at positions spaced apart from the center positions at an equal interval, for example, 190 mm. Each caster 3 includes a rolling wheel 31, a caster body 32 that supports the rolling wheel 31 so as to be rotatable in the circumferential direction, and a mounting base 33 that supports the caster body 32 so as to be rotatable in the horizontal direction. Yes. The mounting base 33 is formed in a substantially rectangular flat plate shape in plan view, screw holes are formed at each corner, and the upper surface of the mounting base 33 is in contact with the lower surfaces of the upper plate parts 23a and 23b. The bolts are inserted and fixed to the lower surfaces of the upper plate portions 23a and 23b.
各取付台３３の下側には、この取付台３３の長手方向および幅方向、すなわち水平方向に沿って回転可能にキャスター本体３２がそれぞれ取り付けられている。よって、キャスター本体３２は、上板部２３ａ，２３ｂの下面に沿って、すなわち底板部２１の垂直方向を回転軸Ａとして回転可能とされている。キャスター本体３２の下部には、タイヤである転動輪３１が水平方向を回転軸Ｂとして回転可能に支持されて取り付けられている。転動輪３１は、荷台本体２の長手方向に直交する水平軸回りに回転可能であり、荷台本体２を水平方向に移動可能にさせる。ここで、各転動輪３１は、この転動輪３１の外周面が、荷台本体２の底板部２１の下面よりも下方に、例えば２０ｍｍほど突出するように取り付けられている。 The caster main body 32 is attached to the lower side of each mounting base 33 so as to be rotatable along the longitudinal direction and the width direction of the mounting base 33, that is, the horizontal direction. Therefore, the caster main body 32 is rotatable along the lower surface of the upper plate portions 23 a and 23 b, that is, with the vertical direction of the bottom plate portion 21 as the rotation axis A. A rolling wheel 31, which is a tire, is supported and attached to the lower portion of the caster main body 32 so as to be rotatable about the horizontal direction as the rotation axis B. The rolling wheels 31 are rotatable about a horizontal axis orthogonal to the longitudinal direction of the cargo bed main body 2 and make the cargo bed main body 2 movable in the horizontal direction. Here, each rolling wheel 31 is attached so that the outer peripheral surface of this rolling wheel 31 protrudes below the lower surface of the bottom plate portion 21 of the cargo bed body 2 by, for example, about 20 mm.
さらに、各キャスター３が取り付けられた状態で、荷台本体２の上板部２３ａ，２３ｂの上側面には、例えば１０ｍｍの厚さ寸法を有するゴムマット４が取り付けられている。このゴムマット４は、上板部２３ａ，２３ｂの長さ寸法に等しい、例えば５１０ｍｍの長さ寸法を有するとともに、上板部２３ａ，２３ｂの幅寸法に等しい、例えば１５０ｍｍの幅寸法を有する矩形平板状に形成され、上板部２３ａ，２３ｂの上面全体を覆っている。 Further, with each caster 3 attached, a rubber mat 4 having a thickness of 10 mm, for example, is attached to the upper side surfaces of the upper plate portions 23a, 23b of the cargo bed body 2. The rubber mat 4 has a rectangular flat plate shape having a length dimension equal to the length dimension of the upper plate portions 23a and 23b, for example, 510 mm, and a width dimension equal to the width dimension of the upper plate portions 23a and 23b, for example, 150 mm. And covers the entire upper surface of the upper plate portions 23a, 23b.
次に、上記一実施形態に係る荷台装置１の作用効果について説明する。 Next, the effect of the loading platform apparatus 1 which concerns on the said one Embodiment is demonstrated.
まず、例えばＨ鋼にて形成された構造物等の被搬送物の下端部（Ｈ鋼の部分）等が、荷台装置１の一対の側板部２２ａ，２２ｂ間の幅寸法より小さな幅寸法である場合には、荷台装置１の上板部２３ａ，２３ｂ上のゴムマット４上に被搬送物の下端部等を載置させずに、この被搬送物の下端部を荷台装置１の一対の側板部２２ａ，２２ｂ間に嵌合させて底板部２１の補強底板材２１ｂ上に載置させる。このとき、荷台装置１は、キャスター３の転動輪３１の外周面が底板部２１の下面よりも、２０ｍｍほど下方に突出しており、底板部２１の補強底板材２１ｂの上面までの厚さが、約２５ｍｍほどであるため、被搬送物の設置面から、約４５ｍｍほど搬送物を持ち上げるだけで、被搬送物を荷台装置１にて搬送可能な状態にできる。 First, for example, a lower end portion (H steel portion) of a transported object such as a structure formed of H steel has a width dimension smaller than a width dimension between the pair of side plate portions 22a and 22b of the loading platform apparatus 1. In this case, the lower end portion of the object to be conveyed is not placed on the rubber mat 4 on the upper plate portions 23 a and 23 b of the loading platform device 1, and the lower end portion of the conveyed object is used as a pair of side plate portions of the loading platform device 1. It fits between 22a and 22b, and is mounted on the reinforcement bottom board material 21b of the baseplate part 21. As shown in FIG. At this time, in the loading platform device 1, the outer peripheral surface of the rolling wheel 31 of the caster 3 protrudes downward by about 20 mm from the lower surface of the bottom plate portion 21, and the thickness of the bottom plate portion 21 to the upper surface of the reinforcing bottom plate material 21b is Since the distance is about 25 mm, the object to be conveyed can be conveyed by the loading platform device 1 by only lifting the object by about 45 mm from the installation surface of the object to be conveyed.
すなわち、被搬送物を余り持ち上げることなく、言い換えると被搬送物を余り高くすることなく、被搬送物を搬送することが可能となるため、例えば天井までの高さや、出入口の扉の高さが低い場合等の狭いスペースであっても、重量物である被搬送物を適切に搬送することができる。特に、荷台装置１の複数のキャスター３の転動輪３１の外周面における、荷台本体２の底板部２１の下面からの下方への突出量を、荷台装置１に載置される被搬送物が搬送可能な必要最小限の量にすることによって、被搬送物をより持ち上げずに搬送することが可能となるから、例えば、被搬送物の高さに略等しい狭いスペースであっても、被搬送物を適切に搬送することができる。また同時に、被搬送物を重心が低い位置で搬送できるので、搬送時における被搬送物の重心を安定でき、搬送時の被搬送物の転倒等をより適切に抑制することができる。 That is, since it is possible to transport the transported object without lifting the transported object too much, in other words, without increasing the transported object too much, for example, the height to the ceiling or the height of the door of the entrance / exit Even in a narrow space such as when it is low, it is possible to appropriately convey a heavy object to be conveyed. In particular, on the outer peripheral surface of the rolling wheels 31 of the plurality of casters 3 of the loading platform device 1, the amount of the object to be transported placed on the loading platform device 1 conveys the downward projection amount from the lower surface of the bottom plate portion 21 of the loading platform body 2. By making the necessary minimum amount possible, it becomes possible to transport the object to be transported without further lifting. For example, even in a narrow space substantially equal to the height of the object to be transported, Can be transported appropriately. At the same time, since the object to be conveyed can be conveyed at a position where the center of gravity is low, the center of gravity of the object to be conveyed at the time of conveyance can be stabilized, and the fall of the object to be conveyed at the time of conveyance can be more appropriately suppressed.
また、荷台装置１の上板部２３ａ，２３ｂ上のゴムマット４までの高さが、約１４５ｍｍであるため、被搬送物の下端部等が、荷台装置１の一対の側板部２２ａ，２２ｂ間の幅寸法より小さな幅寸法ではない場合であっても、被搬送物の設置面から、約１４５ｍｍほど被搬送物を持ち上げ、荷台装置１のゴムマット４上に載置させることによって、被搬送物を搬送可能にすることができる。よって、比較的高さが低いスペースであっても被搬送物を適切に搬送することができる。 Moreover, since the height to the rubber mat 4 on the upper plate portions 23a and 23b of the loading platform device 1 is about 145 mm, the lower end portion of the object to be conveyed is between the pair of side plate portions 22a and 22b of the loading platform device 1. Even if the width dimension is not smaller than the width dimension, the conveyed object is conveyed by lifting the conveyed object from the installation surface of the conveyed object by about 145 mm and placing it on the rubber mat 4 of the loading platform device 1. Can be possible. Accordingly, the object to be conveyed can be appropriately conveyed even in a space having a relatively low height.
また同時に、荷台装置１の荷台本体２の底板部２１から、一対の側板部２２ａ，２２ｂ、および一対の上板部２３ａ，２３ｂまでを、一枚の鉄板を屈曲等させて長手方向に直交する任意の断面が逆ハット型形状の一枚の板材からなる一体構造とし、荷台本体２の一対の上板部２３ａ，２３ｂの下面に複数のキャスター３を取り付けた構成としている。この結果、荷台本体２の底板部２１上に下端部等を載置させた被搬送物の荷重に伴う応力が、荷台本体２の底板部２１から一対の側板部２２ａ，２２ｂおよび一対の上板部２３ａ，２３ｂまでに亘って分散するようになり、例えば、これら底板部２１、一対の側板部２２ａ，２２ｂ、および一対の上板部２３ａ，２３ｂを別部材にて形成して溶接等にて接続した構成の場合に比べ、比較的大きな重量を有する被搬送物であっても適切に搬送することができる。 At the same time, from the bottom plate portion 21 of the loading platform body 2 of the loading platform device 1 to the pair of side plate portions 22a and 22b and the pair of upper plate portions 23a and 23b, a single iron plate is bent or the like to be orthogonal to the longitudinal direction. An arbitrary cross-section has an integrated structure made of a single plate material having an inverted hat shape, and a plurality of casters 3 are attached to the lower surfaces of a pair of upper plate portions 23a and 23b of the cargo bed body 2. As a result, the stress accompanying the load of the object to be transported with the lower end or the like placed on the bottom plate portion 21 of the cargo bed main body 2 is changed from the bottom plate portion 21 of the cargo bed main body 2 to the pair of side plate portions 22a and 22b and the pair of top plates. For example, the bottom plate portion 21, the pair of side plate portions 22a, 22b, and the pair of upper plate portions 23a, 23b are formed by separate members and welded or the like. Compared with the connected configuration, even a transported object having a relatively large weight can be transported appropriately.
さらに、荷台装置１の荷台本体２の上板部２３ａ，２３ｂの下面に取付台３３を取り付け、この取付台３３の下側に水平方向に沿って回転可能にキャスター本体３２を取り付けた構成としている。よって、複数のキャスター３のキャスター本体３２が、荷台本体２の底板部２１の垂直方向を中心軸として回転可能となり、荷台装置１が底板部２１に沿う方向、すなわち水平方向のいずれの方向にも移動可能となる。よって、荷台装置１の使い勝手を向上することができる。 Furthermore, the mounting base 33 is attached to the lower surface of the upper plate portions 23a and 23b of the base body 2 of the base device 1, and the caster body 32 is rotatably attached to the lower side of the mounting base 33 along the horizontal direction. . Therefore, the caster main bodies 32 of the plurality of casters 3 can rotate about the vertical direction of the bottom plate portion 21 of the loading platform main body 2 as the central axis, and the loading platform device 1 is in a direction along the bottom plate portion 21, that is, in any horizontal direction. It becomes possible to move. Therefore, the usability of the cargo bed apparatus 1 can be improved.
また、補強板部２６ａ，２６ｂの接続片部２６ｄを荷台本体２の屈曲片部２４ａ，２４ｂの内側面に接触させつつ、これら補強板部２６ａ，２６ｂの第２辺を荷台本体２の側板部２２ａ，２２ｂの外側面に接触させ、第１辺および第２辺のそれぞれを上板部２３ａ，２３ｂおよび側板部２２ａ，２２ｂそれぞれの幅方向に沿わせた状態として、これら屈曲片部２４ａ，２４ｂおよび側板部２２ａ，２２ｂに対して溶接等して取り付けた構成としている。さらに、これら補強板部２６ａ，２６ｂと底部補強材２１ｄとを一体にし、補強底板材２１ｂ上に係る負荷を底部補強材２１ｄから各補強板部２６ａ，２６ｂへ分散する構成としている。 Further, the connecting plate portion 26d of the reinforcing plate portions 26a and 26b is brought into contact with the inner side surfaces of the bent piece portions 24a and 24b of the loading platform body 2, and the second sides of these reinforcing plate portions 26a and 26b are set to the side plate portions of the loading platform body 2. The bent piece portions 24a and 24b are brought into contact with the outer surfaces of 22a and 22b, and the first side and the second side are arranged in the width direction of the upper plate portions 23a and 23b and the side plate portions 22a and 22b, respectively. And it is set as the structure attached by welding etc. with respect to the side-plate parts 22a and 22b. Further, the reinforcing plate portions 26a, 26b and the bottom reinforcing member 21d are integrated, and the load on the reinforcing bottom plate member 21b is distributed from the bottom reinforcing member 21d to the reinforcing plate portions 26a, 26b.
この結果、荷台本体２の連続する上板部２３ａ，２３ｂの下面と側板部２２ａ，２２ｂの外側面との間、および底板部２１の上側のスペースを有効活用しつつ、荷台本体２の底板部２１または上板部２３ａ，２３ｂ上のゴムマット４上に被搬送物を載置させた場合に生じる被搬送物の荷重に伴う応力が、底板部２１と一対の側板部２２ａ，２２ｂとの間や、一対の側板部２２ａ，２２ｂと一対の上板部２３ａ，２３ｂとの間へ集中することをより適切に抑制することができる。よって、搬送する被搬送物の荷重に伴う応力の荷台本体２に対する分散をより適切にできるため、比較的大きな重量を有する被搬送物であってもより適切に搬送することができる。 As a result, while effectively utilizing the space between the lower surface of the continuous upper plate portions 23a and 23b and the outer side surfaces of the side plate portions 22a and 22b and the upper side of the bottom plate portion 21 of the loading platform body 2, the bottom plate portion of the loading platform body 2 is used. 21 or the upper plate portion 23a, the stress caused by the load of the carried object caused when mounting the transported object on the rubber mat 4 on 23b, the bottom plate portion 21 and a pair of side plate portions 22a, between the 22b Or it can suppress more appropriately concentrating between a pair of side-plate part 22a, 22b and a pair of upper-plate part 23a, 23b. Therefore, since the stress accompanying the load of the conveyed object to be conveyed can be more appropriately distributed to the bed body 2, even a conveyed object having a relatively large weight can be conveyed more appropriately.
また、これら補強板部２６ａ，２６ｂを平面視略直角三角形状とし、これら補強板部２６ａ，２６ｂが上板部２３ａ，２３ｂと側板部２２ａ，２２ｂとの間から余り外側に突出しない構造としている。このため、被搬送物を搬送する際に、補強板部２６ａ，２６ｂが周辺の障害物等に接触等することを少なくでき、被搬送物の搬送をより適切に行うことができる。 Further, the reinforcing plate portions 26a and 26b have a substantially right-angled triangular shape in plan view, and the reinforcing plate portions 26a and 26b do not protrude outwardly between the upper plate portions 23a and 23b and the side plate portions 22a and 22b. . For this reason, when conveying a to-be-conveyed object, it can reduce that the reinforcement board part 26a, 26b contacts a surrounding obstruction, etc., and can convey a to-be-conveyed object more appropriately.
