Description

【０００１】
【発明の属する技術分野】
本発明は、複数個のブロック等を同時に吊り上げ可能なブロック等の吊上げ装置に関する。
【０００２】
【従来の技術】
従来、舗装用ブロックのように、外形が比較的単純な方形状のものを運搬用トラックに積み込んだり、これを降ろしたり或いは設置場所を移動する場合、板状のパレット上に複数個のブロックを並べて複数段積み重ね、これをフォークリフトによりパレットごと揚げ降ろし或いは移送している。
【０００３】
しかし、上記のような従来のパレットを使用したブロックの揚げ降ろし或いは移送方法では、パレット上に積載した単位当たりのものしかできない。したがって、ブロックをトラックで運搬しこれを実際の施工現場などに降ろす場合、これを保管できる設置場所を必要とし、更にこの保管場所から必要な数だけを施工現場にその都度人力により運ぶ必要があった。
【０００４】
また、ブロックの揚げ降ろしにはフォークリフトを使用する必要があるため、揚げ降ろし場所が狭いところではフォークリフトの運転ができず、トラックからの手降ろし作業で行わなければならない、といった問題点もある。
【０００５】
【発明が解決しようとする課題】
このような従来の欠点を解消するため、出願人は先に特公平７−９１０２０号公報に示すブロック等の吊り上げ装置を出願した。しかし、この吊り上げ装置には、構造が比較的複雑であること、機構的にブロックを左右から挟む挟持力を余り強くすることができず、図面に示すような係止部を有する特殊形状のブロックでないと吊り上げの過程において滑落する虞があること、積み上げられたブロックを複数段同時に吊り上げることが出来ない、等の問題点があった。
【０００６】
【課題を解決するための手段】
本発明は、前記装置に改良を加えて、任意段数のブロック群を選択して又所望の個数に合わせて分割し、移動することが出来るものを提供することを目的としたものであり、その要旨は、水平に設置した横枠材の左右両端部近傍に、Ｘ型に配設したリンク部材の下端部近傍を夫々回動自在となるよう枢着するとゝもに、該リンク部材の上端に夫々回動自在となるように下端を枢着した連結リンク部材の上端を合一して枢軸部で回動自在に枢着し、前記横枠材の中央に立設したガイド板の上下方向に延びたガイド溝内に両連結リンク部材の前記枢軸部を摺動自在となるよう嵌合した構成からなる一対のリンク体を、所定間隔だけ前後に離間して前記横枠材の左右両端部で連結材により又前記リンク部材の対向する下端間を挟持部材で夫々一体に連結するとゝもに、前記一対のリンク体間に門形の吊り上げ部材を横架し、該吊り上げ部材の脚部を前記枢軸部で回動自在に連結するとゝもに、前後一対のリンク体とこのリンク体を連結する左右一対の連結材とにより囲まれた内部空間の上方に、吊り上げるブロック等の上面と当接して挟持部材によるブロック等の挟持段数を決める棒状のストッパーを前記前後一対の横枠材と平行に且つ水平に架設してなり、該前後一対のストッパーをその両端部近傍において前記左右一対の連結材に夫々立設した取付部材の所望位置の固定部に固定することで、ストッパーの架設高さを調整可能となるように構成したことを特徴とするブロック等の吊上げ装置にある。
【０００７】
【発明の実施の形態】
以下、本発明を第１図乃至第３図に示す実施例により詳細に説明するに、図において、１は水平に設置された横枠材で、その左右両端部近傍が夫々斜め上方へ立ち上がったほぼ船底形の形状をしており、この横枠材１は前後に離間して平行に配設した対の前横枠材１Ａと後横枠材１Ｂとから構成されている。
【０００８】
２は前記横枠材１の中央部に立設したガイド板で、該ガイド板２には夫々上下方向に延びたガイド溝３が形成されている。すなわち、前横枠材１Ａの前ガイド板２Ａには前ガイド溝３Ａが形成されており、他方この前ガイド板２Ａより高さの低い後横枠材１Ｂの後ガイド板２Ｂにも後ガイド溝３Ｂが形成されている。
【０００９】
４，５は互いにＸ型に交差するリンク部材で、各リンク部材４，５の下端部近傍は夫々、前記前後の両横枠材１Ａ及び１Ｂ間にあって、両横枠材１Ａ及び１Ｂの左右両端部において連結軸６Ａ，６Ｂにより回動自在となるように枢着されているとゝもに、このリンク部材４，５の上端には連結リンク部材７，８の下端が枢軸７Ａ，８Ａにより夫々回動自在となるように枢着されている。
【００１０】
そして、前記連結リンク部材７，８の上端は合一して枢軸部９で回動自在に枢着されており、該枢軸部９の前方突出部９Ａは前記前ガイド溝３Ａ内に嵌合していて、この前ガイド溝３Ａに沿って上下方向に摺動可能となるように装着され、前記横枠材１、リンク部材４，５、連結リンク部材７，８によりリンク体１０を構成している。
【００１１】
このリンク体１０は、所定間隔だけ前後に離間して平行に立設しており、この前後一対のリンク体１０，１０は、前記横枠材１の左右両端部において連結材１１，１１により夫々一体に連結され、又前記後横枠材１Ｂに立設した後ガイド板２Ｂ，２Ｂ同士は、その上端部において横梁部材１２により一体に連結されているとゝもに、前記リンク部材４と４，５と５間は、その先端部においてほぼ水平状態に設置した挟持部材１３，１３により一体に連結固定されている。
【００１２】
１４は門型の吊り上げ部材で、山形の吊り部１４Ａの中央にはクレーンにより吊り上げる際のフックを差し込むための穴１５が形成されており、前記吊り部１４Ａの両端部から夫々垂下した前後に対をなす脚部１４Ｂ，１４Ｂの下端部は、この両脚部１４Ｂ，１４Ｂ間に挿入された連結リンク部材７，８の上端部と前記枢軸部９で回動自在となるように連結されている。
【００１３】
１６は固定用フックで、前記山形の吊り部１４Ａの中央から垂下しており、この固定用フック１６と、前記横梁部材１２の中央部上面に立設した取付板１７から水平に突出する前記固定用フック１６と係止する突起１８とにより、前記リンク体１０を収縮状態で固定するための固定手段が構成されている。
【００１４】
１９，１９は前記連結材１１と１１間に橋渡して横架した棒状のストッパーで、前記横枠材１と平行に延びており、前後一対の前記リンク体１０，１０と、このリンク体１０を連結する左右一対の連結材１１，１１とにより囲まれた内部空間Ｓ内の上方に水平状態で架設されており、両脚２０Ａ，２０Ａの下端を前記連結材１１に固定して立設した門形の取付部材２０に装着されている。
【００１５】
２１は前記ストッパー１９を挿入するパイプで、図示の実施例では前記両脚２０Ａの上端部に上下二段に２つ固定されており、上段又は下段のパイプ２１を選択してストッパー１９の両端を挿入することによりこのストッパー１９の高さを自在に調節して、吊り上げるブロックの段数や挟持部材１３，１３によるブロックの挟持位置等を選べるように構成されている。
【００１６】
次に、本発明装置の作用について説明すると、図２に示すように、本装置をその横枠材１の底辺を接地せしめた状態で地面上におくと、リンク体１０はその自重により各枢軸６Ａ，６Ｂ，７Ａ，８Ａ，９等を回転軸として上下方向に縮み、リンク体１０と一緒に下降した吊り上げ部材１４と横枠材１と一体に固定された横梁部材１２とが接近する。
【００１７】
ここで、前記固定用フック１６を前記突起１８に引っかけ、前記リンク体１０が縮んだ状態に固定する。そしてこの状態で、吊り上げ部材１４の穴１５内に図示しないクレーンのフックを挿入して装置全体を持ち上げ、並べて複数段積み重ねられているブロックＷの上方から下ろすと、内部空間Ｓ内を通過したブロックＷの最上段にあるブロックＷ１の上面がストッパー１９と当接する。
【００１８】
ストッパー１９がブロックＷ１の上面と当接したこの位置で本装置の下降を停止し、前記固定用フック１６を前記突起１８から外す。その後、クレーンにより本装置を持ち上げると、吊り上げ部材１４はガイド溝３内に嵌合した枢軸部９の前方突出部９Ａに案内され、ガイド溝３Ａに沿って上昇する。
【００１９】
その結果、図３に示すように、前記リンク体１０は各枢軸６Ａ，６Ｂ，７Ａ，８Ａ，９等を回転軸として上下方向に延び、リンク部材４，５の先端部は互いに接近する方向に移動し、該先端部に装着した挟持部材１３，１３により数段下にあり且つ最も外側に位置する複数個のブロックをその側面から挟み付ける。
【００２０】
そして、更に本装置を上昇させることにより、挟持部材１３，１３によるブロックに対する挟持力が強化し、複数個のブロックが同時に吊り上げられることになるので、これを所望位置まで移動させて降ろす。このとき、吊り上げられたブロックの下面が地表面に接地した後もやや下降せしめると、前記リンク体１０は自重により上下方向に次第に縮み、リンク部材４，５の先端部に装着した挟持部材１３，１３が互いに離反する方向に移動して挟持力が解消し、ブロックはその場に降ろされることになる。
【００２１】
【発明の効果】
本発明に係るブロック等の吊上げ装置は、上記のように、水平に設置した横枠材の左右両端部近傍に、Ｘ型に配設したリンク部材の下端部近傍を夫々回動自在となるよう枢着するとゝもに、該リンク部材の上端に夫々回動自在となるように下端を枢着した連結リンク部材の上端を合一して枢軸部で回動自在に枢着し、前記横枠材の中央に立設したガイド板の上下方向に延びたガイド溝内に両連結リンク部材の前記枢軸部を摺動自在となるよう嵌合した構成からなる一対のリンク体を、所定間隔だけ前後に離間して前記横枠材の左右両端部で連結材により又前記リンク部材の対向する下端間を挟持部材で夫々一体に連結するとゝもに、前記一対のリンク体間に門形の吊り上げ部材を横架し、該吊り上げ部材の脚部を前記枢軸部で回動自在に連結するとゝもに、前後一対のリンク体とこのリンク体を連結する左右一対の連結材とにより囲まれた内部空間の上方に、吊り上げるブロック等の上面と当接して挟持部材によるブロック等の挟持段数を決める棒状のストッパーを前記前後一対の横枠材と平行に且つ水平に架設してなり、該前後一対のストッパーをその両端部近傍において前記左右一対の連結材に夫々立設した取付部材の所望位置の固定部に固定することで、ストッパーの架設高さを調整可能となるように構成したものであるから、任意段数のブロック群を選択して移動することができ、又所望の個数に合わせて分割して移動することが出来る。従って、作業時間を大幅に短縮することができ、作業者の労力負担も低減することができるとゝもに、比較的簡単な構成なので安価に製作できる。また運搬用トラックに付設されているクレーンを利用することが出来るため、作業スペースがない狭い場所でも積み降ろしが可能で、且つフオークリフトの設備投資も不必要であるといった諸効果がある。

[Prior art]
Conventionally, when a block having a relatively simple outer shape, such as a paving block, is loaded on a transport truck, or is moved down or moved, a plurality of blocks are placed on a plate-like pallet. Multiple tiers are stacked side by side, and the pallet is lifted or transferred by a forklift.
[0003]
However, the conventional method of lifting and transferring blocks using the pallet as described above can only perform the unit loaded on the pallet. Therefore, when transporting the block by truck and dropping it to the actual construction site, etc., it is necessary to have an installation place where it can be stored, and it is necessary to transport only the necessary number from this storage place to the construction site manually. It was.
[0004]
In addition, since it is necessary to use a forklift for lifting and lowering the block, there is a problem that the forklift cannot be operated in a place where the lifting and lowering is narrow and must be carried out by hand-off work from the truck.

In order to eliminate such a conventional defect, the applicant previously applied for a lifting device such as a block disclosed in Japanese Patent Publication No. 7-91020. However, this lifting device has a relatively complicated structure, and cannot mechanically increase the clamping force to sandwich the block from the left and right, and has a specially shaped block having a locking portion as shown in the drawing. Otherwise, there are problems such as the possibility of sliding off during the lifting process, and that the stacked blocks cannot be lifted simultaneously in a plurality of stages.
[0006]
[Means for Solving the Problems]
An object of the present invention is to provide an improvement to the above-described apparatus so that a block group having an arbitrary number of stages can be selected, divided into a desired number, and moved. The gist is that when the pivot member is pivotally attached to the vicinity of the left and right ends of the horizontally installed horizontal frame member so that the vicinity of the lower end portion of the link member arranged in the X shape can be freely rotated, The upper ends of the connecting link members pivoted at the lower ends so as to be pivotable are united and pivotally pivoted at the pivot portion, in the vertical direction of the guide plate erected at the center of the horizontal frame member A pair of link bodies having a configuration in which the pivot portions of both connecting link members are slidably fitted in the extended guide grooves are separated from each other by a predetermined distance at the left and right ends of the horizontal frame member. The connecting members also integrally hold the opposing lower ends of the link members with clamping members. When tied, a portal-shaped lifting member is horizontally mounted between the pair of link bodies, and when the legs of the lifting member are pivotally connected to the pivot portion, the pair of front and rear link bodies and Above the internal space surrounded by the pair of left and right connecting members that connect the link bodies, a bar-shaped stopper that determines the number of clamping steps of the block or the like by the clamping member by contacting the upper surface of the lifting block or the like By fixing the pair of front and rear stoppers in parallel with the frame material to the fixing portions at desired positions of the mounting members respectively erected on the pair of left and right connecting members in the vicinity of both ends thereof, the stoppers The lifting device for a block or the like is characterized in that it is configured to be adjustable in height .

Thus, the height of the stopper 19 can be freely adjusted to select the number of blocks to be lifted, the clamping position of the blocks by the clamping members 13 and 13, and the like.
[0016]
Next, the operation of the device of the present invention will be described. As shown in FIG. 2, when the device is placed on the ground with the bottom of the horizontal frame member 1 grounded, the link body 10 is pivoted by its own weight. 6A, 6B, 7A, 8A, 9 and the like are rotated in the vertical direction and the lifting member 14 lowered together with the link body 10 and the cross beam member 12 fixed integrally with the horizontal frame member 1 approach each other.
[0017]
Here, the fixing hook 16 is hooked on the protrusion 18 to fix the link body 10 in a contracted state. In this state, a crane hook (not shown) is inserted into the hole 15 of the lifting member 14 to lift the entire apparatus, and when it is lowered from above the blocks W stacked in a plurality of stages, the block that has passed through the internal space S is passed. The upper surface of the block W1 at the uppermost stage of W comes into contact with the stopper 19.
[0018]
At this position where the stopper 19 is in contact with the upper surface of the block W1, the lowering of the apparatus is stopped, and the fixing hook 16 is removed from the protrusion 18. Thereafter, when the apparatus is lifted by the crane, the lifting member 14 is guided by the forward projecting portion 9A of the pivot 9 fitted in the guide groove 3, and ascends along the guide groove 3A.

[0020]
Further, by further raising the apparatus, the clamping force of the clamping members 13 and 13 on the block is strengthened, and a plurality of blocks are lifted at the same time, so this is moved to a desired position and lowered. At this time, when the lower surface of the suspended block is lowered slightly after contacting the ground surface, the link body 10 gradually contracts in the vertical direction due to its own weight, and the holding members 13 attached to the distal ends of the link members 4 and 5, 13 moves in a direction away from each other, the clamping force is eliminated, and the block is lowered to the spot.
[0021]
【The invention's effect】
As described above, the lifting device such as a block according to the present invention is rotatable in the vicinity of the left and right end portions of the horizontally installed horizontal frame member and in the vicinity of the lower end portion of the link member disposed in the X shape. When the frame is pivotally attached, the upper end of the connecting link member pivotally attached to the upper end of the link member so as to be pivotable is united and pivotally attached at the pivotal portion, and the horizontal frame A pair of link bodies composed of a structure in which the pivot portions of both connecting link members are slidably fitted in guide grooves extending in the vertical direction of a guide plate erected at the center of the material, are moved back and forth by a predetermined distance. When the left and right ends of the horizontal frame member are connected to each other by a connecting member and between the opposing lower ends of the link member are integrally connected by a sandwiching member, a portal-shaped lifting member is formed between the pair of link bodies. The leg part of the lifting member is pivotally connected to the pivot part. At the same time, above the internal space surrounded by the pair of front and rear link bodies and the pair of left and right connecting members that connect the link bodies, the upper surface of the lifting block or the like is brought into contact with the clamping member by the clamping member. A rod-like stopper for determining the number of steps is installed in parallel and horizontally with the pair of front and rear horizontal frame members, and the pair of front and rear stoppers are installed on the pair of left and right connecting members in the vicinity of both ends thereof. Since it is constructed so that the height of the stopper can be adjusted by fixing it to the fixed part at the desired position, it is possible to select and move the block group of any number of stages, and to the desired number It can be divided and moved together. Therefore, the work time can be greatly shortened and the labor burden on the operator can be reduced. In addition, since the structure is relatively simple, it can be manufactured at a low cost. Moreover, since the crane attached to the transport truck can be used, there are various effects that loading and unloading is possible even in a narrow place where there is no work space, and the capital investment of the forklift is unnecessary.
