Description

この発明は、荷役用に利用するパレットに装着する装置で、パレット表面が撓むことなく吊り下げることができる支持装置に関するものである。   BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a support device that is mounted on a pallet used for cargo handling and that can be hung without bending the pallet surface.

荷役用パレットとしては、表裏面には並列に配した長方形状の平板と、表裏面の中間部に桁材を打ち付けた基本的構造が広く知られている。そして、桁材によって形成された空間部にフォークリフトの2本のフォークを挿入し、パレットを上下させて移動させるのが一般的である。また、パレットを構成する素材としても重量物を積載する必要があるため、合成樹脂やアルミ材などより強い素材を用いた構造も提案されている。   As a cargo handling pallet, a rectangular flat plate arranged in parallel on the front and back surfaces, and a basic structure in which a girder material is struck at an intermediate portion between the front and back surfaces are widely known. In general, two forks of a forklift are inserted into a space formed by the girder material, and the pallet is moved up and down. Further, since it is necessary to load a heavy material also as a material forming the pallet, a structure using a stronger material such as a synthetic resin or an aluminum material has been proposed.

ところで、荷役用パレットの利用法としてはフォークリフトによって搬送するだけでなく、フォークリフトでは届かない高い位置まで搬送するために、パレットの四隅にリング状の取付部を取り付け、この取付部に先端にフックを設けたワイヤロープを引っ掛け、クレーン装置で懸吊するような用法も広く採用されている。   By the way, in order to use a pallet for cargo handling, not only the pallet is transported by a forklift, but also the pallet is transported to a high position that cannot be reached by a forklift. A method of hanging the provided wire rope and suspending it with a crane device has also been widely adopted.

特開2000−159474号公報JP 2000-159474 A

特許文献1は出願人が先に発明したものであり、パレットの両側に各パイプなどの支持材を通し、その両端に設けられた回転自在な掛止リングにワイヤ先端のフックを掛けて懸吊する構成である。そして、支持材がワイヤによる懸吊時に中央部に寄らないように2本の支持材の距離を固定するための寄り止め材を支持材に架け渡している。   Patent Literature 1 is an invention invented by the applicant earlier, in which a support member such as each pipe is passed on both sides of a pallet, and a hook at the end of a wire is hung on rotatable locking rings provided at both ends thereof. It is a configuration to do. Then, a non-stop member for fixing the distance between the two support members is provided over the support members so that the support members do not move toward the center when suspended by the wire.

しかしながら、特許文献1に記載の構成では比較的軽量の積載物であれば確実に支持材間の距離を固定することができるが、重量物を積載した場合にはパレットが撓み、これによって支持材がその撓みに応じて幾分内側方向に傾いてしまう。そうすると、両側の支持材の傾きによって寄り止め材が外れてしまうという問題があった。   However, in the configuration described in Patent Document 1, although the distance between the support members can be reliably fixed if the load is relatively light, the pallet bends when a heavy load is loaded, thereby causing the support member to flex. Are slightly inclined inward according to the deflection. Then, there has been a problem that the stopper material comes off due to the inclination of the support members on both sides.

本発明はこのような従来の問題を解決するもので、パレットに重量物を積載した場合でも安定してパレットを搬送することができるパレットの支持装置を提供することを目的とするものである。   An object of the present invention is to solve such a conventional problem, and an object of the present invention is to provide a pallet supporting device capable of stably transporting a pallet even when a heavy object is loaded on the pallet.

上述した目的を達成するために本発明では、荷役用パレットの通孔に2本の角パイプを平行に挿通し、前記2本の角パイプの両端にワイヤを設けて前記荷役用パレットを懸吊する際に、前記荷役用パレットから飛び出ている前記角パイプに挿通して使用する支持装置であり、この支持装置はパレットの通孔に挿通した2本の角パイプの両端が挿通する位置決め孔を両側に複数並列に並べ、これら両側の位置決め孔を上下から一対の鋼板で挟み込んで一体とすることによって、目的を達成する。2本の角パイプはパレットを懸吊する際のパレットの両側を均等の引き上げ力によって持ち上げるためのものであり、位置決め孔は2本の角パイプが偏らない位置に設定するための構成である。また、一対の鋼板は各位置決め孔を確実に固定するための構成であると同時に、パレット表面に積載した荷物によってパレットが撓む方向に変形することを矯正する作用を行う。すなわち、位置決め孔は一対の鋼板によって挟み込まれて回転方向の位置規制をされているので、この位置決め孔に挿通した角パイプもこれによって回転方向の動きが規制される。 In order to achieve the above object, according to the present invention, two square pipes are inserted in parallel into through holes of a cargo pallet, and wires are provided at both ends of the two square pipes to suspend the cargo pallet. A supporting device to be used by being inserted into the square pipe projecting from the cargo handling pallet, the supporting device having a positioning hole through which both ends of two square pipes inserted through the through holes of the pallet are inserted. The object is achieved by arranging a plurality of side-by-side arrangements on both sides and sandwiching the positioning holes on both sides from above and below with a pair of steel plates and integrating them. The two square pipes are used for lifting both sides of the pallet with a uniform lifting force when suspending the pallet, and the positioning holes are configured to set the two square pipes at a position where they are not biased. Further, the pair of steel plates is configured to securely fix the respective positioning holes, and at the same time, has a function of correcting deformation of the pallet in a direction in which the pallet is bent by the load loaded on the pallet surface. That is, since the positioning hole is sandwiched between a pair of steel plates to regulate the position in the rotation direction, the rectangular pipe inserted into the positioning hole is also restricted from moving in the rotation direction.

さらに、各位置決め孔の上部に鋼板を含んでビス孔を穿孔するという手段を選択的に用いた。これによって、角パイプは挿通方向の動きを規制され、不用意に脱落することがないだけでなく、2本の角パイプと一対の支持装置によって強固なフレームを構成することになり、ねじれなどに対しても強い耐力を有する。上面の鋼板の中央部にハンドルを設ける手段を採用する場合には、比較的重量がある支持装置の運搬を容易とする。 Further, a means of drilling a screw hole including a steel plate above each positioning hole was selectively used. As a result, the movement of the square pipe in the insertion direction is restricted, and not only does not fall out carelessly, but also a solid frame is constituted by the two square pipes and the pair of supporting devices, and torsion etc. It has a high proof stress. When the means for providing the handle at the center of the steel plate on the upper surface is adopted, the relatively heavy supporting device can be easily transported.

さらに、両側の位置決め孔の中間部には鋼板の補強壁面をさらに設けるという手段を用いた。この補強壁面は支持装置の撓み方向に対する応力を受けるように作用し、支持装置の撓みを確実に防止する。 Further, a means was used in which a reinforcing wall surface of a steel plate was further provided at an intermediate portion between the positioning holes on both sides. The reinforcing wall acts to receive a stress in the bending direction of the support device, and reliably prevents the support device from bending.

本発明によれば、パレットの支持装置は両側に複数個並列に設けられた通孔を上下2枚の鋼板で挟み込んでいるので重量物を積載した場合でもパレットに挿通した角材を確実に固定することができ、パレット自体の撓みに対する補強とすることができるとともに、支持装置が角材から外れることがない。したがって、安全なパレットの支持装置を提供することができた。   According to the present invention, since the pallet support device has a plurality of through holes provided in parallel on both sides sandwiched between the upper and lower two steel plates, even when a heavy object is loaded, the square member inserted into the pallet is securely fixed. This can provide reinforcement against the deflection of the pallet itself and prevent the support device from coming off the square bar. Therefore, a safe pallet support device could be provided.

以下、本発明の好ましい実施の形態を添付した図面に従って説明する。図1は本発明の一実施形態を示す斜視図、図2は分解斜視図であって、公知のパレットに本発明の支持装置を取り付けた状態を示す。ここで、1はパレット本体で、表裏面板2・3、及び桁材4によって構成されている。なお、パレット本体は本発明においては構成要素ではないので、公知のパレットであって表裏面材2・3の間に奥行方向に通孔5が形成されているものであれば足りる。6・6はパレット本体1の通孔5に挿通する角パイプであり、2本を並行してパレット本体1の通孔5に差し込んでいる。7は角パイプ6の両端に設けられたワイヤの係止部として機能するリング状の掛止輪であって、回転自在、あるいは回転しないいずれの構成であってもよい。そして、四隅に出現する掛止輪7にワイヤ8〜8を掛け、クレーン装置(図示せず)などによって懸吊する。   Hereinafter, preferred embodiments of the present invention will be described with reference to the accompanying drawings. FIG. 1 is a perspective view showing an embodiment of the present invention, and FIG. 2 is an exploded perspective view showing a state in which a supporting device of the present invention is mounted on a known pallet. Here, reference numeral 1 denotes a pallet body, which is constituted by front and back plates 2 and 3 and a beam member 4. Since the pallet body is not a constituent element in the present invention, any known pallet having a through hole 5 in the depth direction between the front and back members 2 and 3 is sufficient. Reference numeral 6.6 denotes a square pipe inserted into the through hole 5 of the pallet body 1, and two pipes are inserted into the through hole 5 of the pallet body 1 in parallel. Reference numeral 7 denotes a ring-shaped retaining ring which functions as a wire locking portion provided at both ends of the square pipe 6, and may be either rotatable or non-rotatable. Then, wires 8 to 8 are hung on the retaining rings 7 appearing at the four corners, and suspended by a crane device (not shown) or the like.

角パイプ6・6は、パレット1の通孔5の両側に平行に挿通したうえで、本発明の支持装置9によって位置決めされる。支持装置9の構成は、図3および図4に詳細に示したように、両側にそれぞれ4個の位置決め孔10…10が設けられている。より具体的には、位置決め孔10は引き抜きで成形した角パイプを均等幅で切断して得る。ただし、位置決め孔10を製造する方法はこれに限定するものではなく、角パイプ6を密に挿通することができる内側口径を有する構造であれば公知の方法で製造することが可能である。そして、位置決め孔10をそれぞれ両側に4個並べた状態で、上下を鋼板11・11で挟み込んで接続し、一例として溶接などで固定している。なお、位置決め孔10は本実施形態では両側に4個ずつ設けているが、位置決め孔10を設ける意味は角パイプ6を挿通する位置によって角パイプ6・6間の距離を適宜決定するためであるから、4個に制限する必要はない。また、位置決め孔10とは、単に「孔」を意味するのではなく、この孔を形成するための周囲のフレーム部を含んだ概念を指し、物理的に幅を有しているものである。また、鋼板11についても、位置決め孔10の幅に見合った幅を有する鋼板を採用する。ただし、位置決め孔10の幅と鋼板11の幅を正確に一致させる必要はない。12は持ち運びのためのハンドルである。基本的な構成としては、両側に設けられた位置決め孔10と、鋼板11・11で十分であるが、撓み強度を補強するために、本実施形態では一番内側の位置決め孔10a間に鋼材の補強壁面13を前後側に設けている。したがって、支持装置9の中央部は断面が縦長の矩形になっている。14は各位置決め孔10に対応して位置決め孔10の上部に鋼板11を含んで穿孔されたビス孔であり、角パイプ6を挿通した状態でビス15をビス孔14に羅合して角パイプ6を締め付けることによって、角パイプ6が動かないように固定している。   The square pipes 6, 6 are inserted in parallel on both sides of the through hole 5 of the pallet 1 and are positioned by the support device 9 of the present invention. As shown in detail in FIGS. 3 and 4, the support device 9 has four positioning holes 10 on each side. More specifically, the positioning hole 10 is obtained by cutting a square pipe formed by drawing at an equal width. However, the method for manufacturing the positioning hole 10 is not limited to this, and a known method can be used as long as the structure has an inner diameter through which the square pipe 6 can be densely inserted. Then, in a state where four positioning holes 10 are arranged on both sides, the upper and lower sides are sandwiched and connected by steel plates 11 and 11, and are fixed by welding or the like as an example. Although four positioning holes 10 are provided on both sides in this embodiment, the purpose of providing the positioning holes 10 is to appropriately determine the distance between the square pipes 6 depending on the position where the square pipe 6 is inserted. Therefore, there is no need to limit the number to four. The positioning hole 10 does not simply mean a “hole” but refers to a concept including a surrounding frame portion for forming the hole, and has a physical width. Also, as the steel plate 11, a steel plate having a width corresponding to the width of the positioning hole 10 is employed. However, it is not necessary that the width of the positioning hole 10 and the width of the steel plate 11 match exactly. Reference numeral 12 denotes a handle for carrying. As a basic configuration, the positioning holes 10 provided on both sides and the steel plates 11 are sufficient. However, in order to reinforce the bending strength, in the present embodiment, the steel material is inserted between the innermost positioning holes 10a. Reinforcing wall surfaces 13 are provided on the front and rear sides. Therefore, the center of the support device 9 has a vertically long rectangular cross section. Reference numeral 14 denotes a screw hole formed in the upper part of the positioning hole 10 corresponding to each of the positioning holes 10 and including the steel plate 11. A screw 15 is joined to the screw hole 14 while the square pipe 6 is inserted, and a square pipe is formed. By tightening 6, the square pipe 6 is fixed so as not to move.

このように構成された装置を用いる場合には、先ずパレット1の内部の通孔5に角パイプ6・6を挿通し、それぞれをパレット1の幅方向両側に据え置く。次に本発明装置の支持装置9を角パイプ6・6がパレット1から飛び出ている場所に適応し、位置決め孔10に角パイプ6・6を挿通する。この場合、角パイプ6を4個の位置決め孔10の何れに挿通するかについては、角パイプ6・6をワイヤなどによって懸吊した際に傾かないように均等位置になる位置決め孔10を決定する。両側の支持装置9・9の位置決め孔10に角パイプ6・6を挿通した後に、ビス15をビス孔14に予め形成された内ネジに羅合することによって完成する。その後は角パイプ6の両側端部に設けられた掛止輪7にワイヤを引っ掛けて作業が完了する。   In the case of using the apparatus configured as described above, first, the square pipes 6 are inserted into the through holes 5 inside the pallet 1, and the pipes 6 are respectively set on both sides in the width direction of the pallet 1. Next, the supporting device 9 of the apparatus of the present invention is adapted to a place where the square pipes 6.6 protrude from the pallet 1, and the square pipes 6.6 are inserted into the positioning holes 10. In this case, regarding which of the four positioning holes 10 the square pipe 6 is to be inserted into, the positioning holes 10 which are positioned evenly so as not to be inclined when the square pipes 6 are suspended by wires or the like are determined. . After the square pipes 6.6 are inserted into the positioning holes 10 of the support devices 9.9 on both sides, screws 15 are engaged with internal screws formed in the screw holes 14 in advance to complete the process. Thereafter, the wire is hooked on the retaining rings 7 provided at both ends of the square pipe 6 to complete the work.

本実施形態では、パレット1の表面板2に荷物を積載した場合、これらの荷物が比較的重量物である場合でも一対の支持装置9・9と一対の角パイプ6・6によってフレームを形成しているので、パレット1に加わる荷重はこのフレームで受けることになるから、パレット1が不必要に撓むことがない。   In this embodiment, when a load is loaded on the surface plate 2 of the pallet 1, even if the load is relatively heavy, a frame is formed by the pair of support devices 9.9 and the pair of square pipes 6.6. Since the load applied to the pallet 1 is received by this frame, the pallet 1 is not unnecessarily bent.
