Description

本発明は、トレーラーの荷台に積載した鋼管や鋼板コイル等の円筒状の物体（以下、円筒体という）の転落を防止するために、荷台に装着されるスタンションに関するものである。   The present invention relates to a stanchion mounted on a cargo bed in order to prevent the fall of a cylindrical object (hereinafter referred to as a cylindrical body) such as a steel pipe or a steel plate coil loaded on a cargo bed of a trailer.

トレーラーに円筒体を積載して運搬するにあたって、荷台から円筒体が転落するのを防止するために、スタンションと呼ばれる柱体のストッパーが荷台に装着される。その例を図２に断面図として示す。以下では円筒体の例である鋼管について説明する。
図２に示すように、スタンション１は、荷台２に設けた挿入孔４に下部を挿入して固定し、上部を荷台２上に起立させることによって、鋼管３の転落を防止するものである。鋼管３の転落を防止するためには、スタンション１に鋼管３が接触した状態で、鋼管３の荷重によってスタンション１の脱落や破損を生じさせないように、スタンション１を固定する必要がある。そのため、荷台２の側縁から所定の距離の内側に挿入孔４を設けることによって、挿入孔４の強度を保ち、その変形を防止している。 In order to prevent the cylindrical body from falling from the loading platform when carrying the cylindrical body on the trailer, a column stopper called a stanchion is attached to the loading platform. The example is shown as a cross-sectional view in FIG. Below, the steel pipe which is an example of a cylindrical body is demonstrated.
As shown in FIG. 2, the stanchion 1 prevents the steel pipe 3 from falling by inserting and fixing a lower portion into an insertion hole 4 provided in the loading platform 2 and raising the upper portion on the loading platform 2. In order to prevent the steel pipe 3 from falling, it is necessary to fix the stanchion 1 so that the stanchion 1 is not dropped or damaged by the load of the steel pipe 3 in a state where the steel pipe 3 is in contact with the stanchion 1. Therefore, by providing the insertion hole 4 inside a predetermined distance from the side edge of the cargo bed 2, the strength of the insertion hole 4 is maintained and its deformation is prevented.

ところが図２に示すような棒状のスタンション１を用いた場合は、スタンション１の外側に位置する荷台２上には鋼管３を積載できないので、積載量の低下を招く。そこでスタンション１を荷台２の側縁近辺に十分な強度をもって固定することによって、積載量の低下を抑制する技術が種々検討されている。
たとえば特許文献１には、荷台上に設置する横梁に幅調整用の溝を設け、その溝にスタンションをピンで固定する技術が開示されている。 However, when the rod-like stanchion 1 as shown in FIG. 2 is used, the steel pipe 3 cannot be loaded on the loading platform 2 located outside the stanchion 1, which causes a reduction in the loading capacity. Therefore, various techniques for suppressing the decrease in the loading amount by fixing the stanchion 1 near the side edge of the loading platform 2 with sufficient strength have been studied.
For example, Patent Document 1 discloses a technique in which a width adjusting groove is provided in a horizontal beam installed on a cargo bed, and a stanchion is fixed to the groove with a pin.

また特許文献２には、荷台上に設置する横梁にガイドレールを設け、積荷の重量によってスタンションを自動的に移動させて鋸状ストッパで固定する技術が開示されている。
これらのスタンションは、いずれも複雑な構造を有しており、スタンションの製造コストが上昇するばかりでなく、メンテナンスの負荷が増大する。
また、荷物の長さや形状に合わせてスタンションを取外したり、長手方向の取付け位置を変更する場合もあるため、スタンションは容易に取付けと取外しを行なえる構成にする必要がある。しかし特許文献１、２に開示されたスタンションは、構造が複雑であるから、取付け、取外しに長時間を要するという問題がある。 Patent Document 2 discloses a technique in which a guide rail is provided on a horizontal beam installed on a loading platform, and a stanchion is automatically moved according to the weight of the load and fixed with a saw-shaped stopper.
Each of these stanches has a complicated structure, which not only increases the manufacturing cost of the stanchions but also increases the load of maintenance.
Further, since the stanchion may be removed according to the length and shape of the load or the longitudinal attachment position may be changed, the stanchion needs to be configured so that it can be easily attached and removed. However, the stanchions disclosed in Patent Documents 1 and 2 have a complicated structure, and thus have a problem that a long time is required for attachment and removal.

As a result, the stanchion is bent into a crank shape, the lower part of the bent part is inserted into the insertion hole of the loading platform, and the upper portion is raised near the side edge of the loading platform, so that the cylindrical body (for example, steel pipe, steel plate coil, etc.) It has been found that the load can be increased and that the load of the cylindrical body applied to the stanchion can be sufficiently supported by bringing the bent portion into contact with the loading platform.

本発明は、このような知見に基づいてなされたものである。
すなわち本発明は、円筒体を搬送するトレーラーの荷台に取付けるスタンションであって、荷台に設けられた挿入孔に挿入される基底部、および荷台の上方に起立して円筒体の転落を防止する支柱部、および基底部と支柱部とをクランク状に連結する接続部を有し、支柱部の上部領域に厚みを基底部よりも薄くした薄肉領域を設け、支柱部の下部領域に厚みを薄肉領域から接続部へ傾斜させた傾斜領域を設け、かつ基底部下面と接続部下面との距離を挿入孔の深さに一致させ、薄肉領域の下端を荷台上の円筒体の中心より低い位置に設定するスタンションである。 The present invention has been made based on such knowledge.
That is, the present invention is a stanchion that is attached to a loading platform of a trailer that transports a cylindrical body, and a base portion that is inserted into an insertion hole provided in the loading platform, and a column that stands above the loading platform and prevents the cylindrical body from falling. And a connecting portion that connects the base portion and the column portion in a crank shape, a thin region having a thickness thinner than that of the base portion is provided in the upper region of the column portion, and a thin region is provided in the lower region of the column portion. An inclined area inclined from the connection part to the connection part is provided, and the distance between the bottom surface of the base part and the connection part bottom surface is made to match the depth of the insertion hole, and the lower end of the thin area is set to a position lower than the center of the cylindrical body on the loading platform. It is a stanchion to do.

本発明によれば、トレーラーで円筒体を運搬するための、簡素な構成を有し簡便に取付けでき、かつ積載量を増加できるスタンションを得ることができる。しかも、そのスタンションは、円筒体の荷重を十分に支持できるので円筒体の運搬に好適であり、産業上格段の効果を奏する。   ADVANTAGE OF THE INVENTION According to this invention, the stanchion which has a simple structure for conveying a cylindrical body with a trailer, can be simply attached, and can increase a load capacity can be obtained. Moreover, the stanchion is suitable for transporting the cylindrical body because it can sufficiently support the load of the cylindrical body, and has a remarkable industrial effect.

図１は、本発明のスタンションを荷台に取付けた例を模式的に示す断面図である。なお、以下では円筒体の例として鋼管について説明する。
本発明のスタンション１は、荷台に設けられた挿入孔に挿入される基底部11、および荷台の上方に起立して鋼管３の転落を防止する支柱部12、および基底部11と支柱部12とをクランク状に連結する接続部13を有する。 FIG. 1 is a cross-sectional view schematically showing an example in which the stanchion of the present invention is attached to a cargo bed. Hereinafter, a steel pipe will be described as an example of a cylindrical body.
The stanchion 1 of the present invention includes a base portion 11 inserted into an insertion hole provided in the loading platform, a support column portion 12 that stands above the loading platform to prevent the steel pipe 3 from falling, and the base portion 11 and the support column portion 12. Has a connecting portion 13 for connecting the two in a crank shape.

トレーラー（図示せず）の荷台２には挿入孔４が設けられており、基底部11は挿入孔４に挿入される。基底部11の上端は、接続部13を介して支柱部12の下端とクランク状に連結される。
ここで、基底部11の下面と接続部13の下面との距離Ｌは、挿入孔４の深さＬと同一である。つまり、スタンション１の基底部11を挿入孔４に挿入することによって、基底部11の下面を挿入孔４の底面に当接させ、かつ接続部13の下面を荷台２の上面に当接させて、スタンション１を固定する。このようにして、荷台２上の鋼管３の荷重がクランク状に屈曲した部位に集中して加わるのを抑制し、スタンション１の脱落や破損を防止する。 An insertion hole 4 is provided in the loading platform 2 of the trailer (not shown), and the base portion 11 is inserted into the insertion hole 4. The upper end of the base portion 11 is connected to the lower end of the support column portion 12 via the connecting portion 13 in a crank shape.
Here, the distance L between the lower surface of the base portion 11 and the lower surface of the connection portion 13 is the same as the depth L of the insertion hole 4. That is, by inserting the base portion 11 of the stanchion 1 into the insertion hole 4, the lower surface of the base portion 11 is brought into contact with the bottom surface of the insertion hole 4 and the lower surface of the connection portion 13 is brought into contact with the upper surface of the loading platform 2. , Stanchion 1 is fixed. In this way, the load of the steel pipe 3 on the loading platform 2 is prevented from being concentrated and applied to the portion bent in a crank shape, and the stanchion 1 is prevented from falling off or being damaged.

しかも図１に示すように、支柱部12を荷台２の側縁近辺に起立させることができるので、従来の棒状のスタンション（図２参照）よりも１対のスタンション１の間隔を広げて、積載量を増加することが可能となる。
支柱部12を安定して起立させるために、支柱部12の下端部の厚みは、基底部11の厚みＷAと同一とすることが好ましい。 Moreover, as shown in FIG. 1, the column portion 12 can be raised in the vicinity of the side edge of the loading platform 2, so that the interval between the pair of stanchions 1 is wider than the conventional bar-like stanchions (see FIG. 2). The amount can be increased.
To erect the struts 12 stably, the thickness of the lower end portion of the support portion 12 is preferably the same as the thickness W A of the base portion 11.

支柱部12の上部領域の厚みＷBは、基底部11の厚みＷAよりも薄く（ＷB＜ＷA）する。厚みを薄くした領域12a（以下、薄肉領域という）は、図１に示すように、支柱部12の外側面を平坦とし、内側面を外側面に接近させて形成する。このようにして薄肉領域12aを支柱部12に設けることによって、１対のスタンション１の間隔をさらに広げて、積載量を一層増加することが可能となる。 The thickness W B of the upper region of the support column 12 is thinner than the thickness W A of the base 11 (W B <W A ). As shown in FIG. 1, the region 12a having a reduced thickness (hereinafter referred to as a thin region) is formed by flattening the outer surface of the support column 12 and bringing the inner surface closer to the outer surface. By providing the thin region 12a in the support column 12 in this way, the distance between the pair of stanchions 1 can be further widened to further increase the loading capacity.

支柱部12の下端は、基底部11と同じ厚みＷAを有するので、接続部13と薄肉領域12aとの間に、厚みを傾斜させた領域12b（以下、傾斜領域という）を設ける。傾斜領域12bにおいても、支柱部12の外側面を平坦とする。つまり傾斜領域12bの内側面を傾斜させる。この傾斜領域12bを設けることによって、荷台２上の鋼管３の荷重がクランク状に屈曲した部位に集中して加わるのを抑制し、スタンション１の脱落や破損を防止する効果が得られる。 The lower end of the strut 12, so has the same thickness W A and base portion 11, between the connecting portion 13 and the thin region 12a, the region 12b which is inclined thickness (hereinafter, referred to as the inclined region) provided. Also in the inclined region 12b, the outer surface of the support column 12 is made flat. That is, the inner surface of the inclined region 12b is inclined. By providing the inclined region 12b, it is possible to suppress the load of the steel pipe 3 on the loading platform 2 from being concentrated on the portion bent in a crank shape and to prevent the stanchion 1 from falling off or being damaged.

薄肉領域12aの下端（すなわち傾斜領域12bの上端）は、荷台２上の鋼管３の中心Ｃよりも低く設定する。トレーラーで運搬する鋼管の直径が複数種類ある場合は、その最小径の鋼管の中心よりも低い位置に、薄肉領域12aの下端を配置する。このようにして、鋼管３の積載量を増加するという薄肉領域12aの効果を有効に発揮することができる。
また、薄肉領域12aの上端部は、図１に示すように、平坦な外側面に近づけるように傾斜させても良い。その結果、スタンション１の軽量化を図ることが可能となり、かつ鋼管３を上方からクレーン等で積載するときにガイドの役割を果たす。 The lower end of the thin region 12a (that is, the upper end of the inclined region 12b) is set lower than the center C of the steel pipe 3 on the loading platform 2. When there are a plurality of diameters of the steel pipes transported by the trailer, the lower end of the thin region 12a is arranged at a position lower than the center of the steel pipe having the smallest diameter. In this way, the effect of the thin region 12a that increases the loading capacity of the steel pipe 3 can be effectively exhibited.
Further, as shown in FIG. 1, the upper end portion of the thin region 12a may be inclined so as to approach the flat outer surface. As a result, it is possible to reduce the weight of the stanchion 1 and to serve as a guide when the steel pipe 3 is loaded from above with a crane or the like.

このようにして支柱部12の外側面を平坦としたスタンション１を対向して取付けることによって、支柱部12の外側面同士の間隔を、道路交通法で制限される車幅の最大値まで広げることが可能となる。
なお、本発明のスタンションを用いると、荷台２上に緩衝材５（たとえば枕木等）を設置することも可能である。 In this way, by mounting the stanchions 1 having the flat outer surface of the support column 12 facing each other, the distance between the outer surfaces of the support columns 12 is increased to the maximum vehicle width limited by the Road Traffic Law. Is possible.
In addition, if the stanchion of this invention is used, it is also possible to install the buffer material 5 (for example, sleepers etc.) on the loading platform 2. FIG.

図３に示すように、トレーラーの荷台２（幅2490mm）にスタンションを取付けて、鋼管３を積載した。図３(a)は本発明のスタンション１を取付けて鋼管３（直径800mm）を積載した例（発明例１）、図３(b)は従来の棒状のスタンションを取付けて鋼管３（直径800mm）を積載した例（比較例１）、図３(c)は本発明のスタンション１を取付けて鋼管３（直径1200mm）を積載した例（発明例２）、図３(d)は従来の棒状のスタンションを取付けて鋼管３（直径1200mm）を積載した例（比較例２）である。なお荷台２上には緩衝材として枕木５を設置した。また、通常の運搬と同様に、滑り止め６を併用した。挿入孔４の位置はいずれも同じである。   As shown in FIG. 3, the stanchion was attached to the loading platform 2 (width 2490 mm) of the trailer, and the steel pipe 3 was loaded. Fig. 3 (a) shows an example (invention example 1) in which a steel pipe 3 (800 mm in diameter) is loaded with the stanchion 1 of the present invention, and Fig. 3 (b) shows a steel pipe 3 (800 mm in diameter) with a conventional rod-like stanchion attached 3 (c) is an example of mounting a stanchion 1 of the present invention and loading a steel pipe 3 (diameter 1200 mm) (invention example 2), and FIG. 3 (d) is a conventional rod-like shape. This is an example (Comparative Example 2) in which a stanchion is attached and a steel pipe 3 (diameter 1200 mm) is loaded. A sleeper 5 is installed on the loading platform 2 as a cushioning material. Moreover, the anti-slip | skid 6 was used together like normal conveyance. The positions of the insertion holes 4 are the same.

直径800mmの鋼管３を積載する場合は、発明例１では５本を俵積みすることができたのに対して、比較例１では３本の俵積みであった。つまり、本発明のスタンションを取付けることによって、鋼管３の積載量を増加することができた。
直径1200mmの鋼管３を積載する場合は、発明例２では３本を俵積みすることができたのに対して、比較例２では１本の平積みであった。つまり、本発明のスタンションを取付けることによって、鋼管３の積載量を増加することができた。荷台２が地面から高い位置にあるトレーラーを使用して直径1200mmの鋼管３を俵積み（３本）すると、道路交通法の高さ制限を超える惧れが生じるが、その場合は２本を平積みすれば良い。２本の平積みであっても、比較例２よりも積載量を増加できる。 In the case where the steel pipes 3 having a diameter of 800 mm are loaded, in Example 1 of the invention, 5 pieces could be piled up, whereas in Comparative Example 1, there were 3 pieces of piled up. In other words, the loading capacity of the steel pipe 3 could be increased by attaching the stanchion of the present invention.
When the steel pipes 3 having a diameter of 1200 mm were loaded, three pieces could be piled up in the invention example 2, whereas in the comparative example 2, it was one flat pile. In other words, the loading capacity of the steel pipe 3 could be increased by attaching the stanchion of the present invention. If a steel pipe 3 with a diameter of 1200 mm is piled up (three) using a trailer with the loading platform 2 at a high position from the ground, the height limit of the Road Traffic Act may be exceeded. Just stack. Even with two flat stacks, the load capacity can be increased as compared with Comparative Example 2.
