Description

本発明は、重量物を搬送する経路にある段差を容易に通過させる等、種々の用途に使用できるジャッキ装置およびそれを使用する重量物の搬送方法に関する。 The present invention relates to a jack apparatus that can be used for various purposes such as easily passing a step on a path for transporting heavy objects, and a method for conveying heavy objects using the jack apparatus.

従来、図１０（ａ）に示すように、床に例えば１ｍ程度の段差６１がある工場やプラントなどの建屋内で左側の高い床に搬入した重量物Ｗを右側の低い床の所定の位置に搬送する場合、低い床の段差６１の近傍に高い床と同じレベルの搬入用ステージ６２を仮設するとともに、搬入用ステージ６２の上の天井の躯体に４台のチェーンブロック６３を取り付けた後、重量物Ｗをチルローラ６４により搬入用ステージ６２上に横引きする。次に、図１０（ｂ）に示すように、４台のチェーンブロック６３を使用して重量物Ｗを吊り上げ、搬入用ステージ６２を取り除き、続いて、図１０（ｃ）に示すように、チェーンブロック６３により重量物Ｗを吊り降ろし、図１０（ｄ）に示すように、チルローラ６４を使用して横引きし、低い床上の所定の位置まで搬送する。 Conventionally, as shown in FIG. 10 (a), a heavy object W carried into a high floor on the left side in a building such as a factory or a plant having a level difference 61 of about 1 m on the floor is placed at a predetermined position on the low floor on the right side. When transporting, a loading stage 62 at the same level as the high floor is temporarily installed in the vicinity of the step 61 on the low floor, and the four chain blocks 63 are attached to the ceiling frame on the loading stage 62, and then the weight is increased. The article W is horizontally pulled onto the loading stage 62 by the chill roller 64. Next, as shown in FIG. 10B, the heavy object W is lifted using the four chain blocks 63, the loading stage 62 is removed, and then, as shown in FIG. The heavy object W is suspended by the block 63, and is horizontally pulled using a chill roller 64 as shown in FIG. 10D, and conveyed to a predetermined position on a low floor.

しかし、このような重量物搬送方法は、搬入用ステージ６２の組み上げとステージ６２の高さの調整が必要であり、準備作業に時間がかかる。また、チェーンブロック６３の取り付けのため、アンカーを打設したり、壁にスリーブを貫通させる等、躯体を傷つけ作業を伴う。チェーンブロック６３を取り付ける天井の躯体の強度を計算しておく必要があるが、躯体が古い場合には計算が不十分になり、実際に重量物を吊り上げると、強度が不足して、重量物を落下させることになる。搬入用ステージ６２を取り除く際に人が吊り上げた重量物Ｗの下で作業することになるため危険を伴うなどの問題がある。 However, such a heavy material transfer method requires assembly of the loading stage 62 and adjustment of the height of the stage 62, and takes time for preparation work. In addition, the attachment of the chain block 63 involves an operation of damaging the housing such as placing an anchor or passing a sleeve through the wall. It is necessary to calculate the strength of the frame of the ceiling to which the chain block 63 is attached. However, if the frame is old, the calculation will be insufficient. If the heavy object is actually lifted, the strength will be insufficient, It will be dropped. When removing the carrying-in stage 62, there is a problem such as a danger because the work is performed under the heavy object W lifted by a person.

従来、段差を解消して重量物を搬送するための装置として、特許文献１には、昇降レールが敷設された昇降ステージの四角に摺動子を設け、該摺動子を４つのガイド支柱に嵌合して昇降自在にし、天井部分に設置されたジャッキの吊りロッドで昇降ステージを昇降させる重量物搬送機構が開示されている。 Conventionally, as an apparatus for eliminating a level difference and conveying a heavy object, Patent Document 1 provides a slider on a square of an elevating stage on which an elevating rail is laid, and the slider is used as four guide columns. There is disclosed a heavy material transport mechanism that is fitted and can be moved up and down and lifts and lowers a lifting stage with a suspension rod of a jack installed on a ceiling portion.

また、特許文献２には、段差の下段に仮受け台を設置し、エアジャッキと仮受け台を用いて重量物（プレキャストボックスカルバート）を少しずつ持ち上げて重量物の下方にレベル調整材とエアキャスタを配置し、エアキャスタで重量物を仮受け台に移動して、段差の上段を搬送する工法が開示されている。 In Patent Document 2, a temporary cradle is installed at the lower stage of a step, and a heavy object (precast box culvert) is lifted little by little using an air jack and a temporary cradle, and a level adjusting material and an air are placed below the heavy object. A method of disposing a caster, moving a heavy object to a temporary cradle with an air caster, and conveying an upper stage of a step is disclosed.

特許文献３には、縦フレームと上部ブレースからなる門型で、縦フレームの下端にジャッキを介してキャスタ付の支持部材を設け、上部ブレースにスライダーを介して吊り荷を吊り下げるジャッキング装置を、段差の前後に２台配置して、一方のジャッキング装置から他方のジャッキング装置に吊り荷を移し換える装置が開示されている。 Patent Document 3 discloses a jacking device that is a gate type composed of a vertical frame and an upper brace, and is provided with a support member with a caster via a jack at the lower end of the vertical frame and suspends a suspended load via a slider on the upper brace. An apparatus that disposes two loads before and after the step and transfers a suspended load from one jacking apparatus to the other jacking apparatus is disclosed.

特許文献４には、重量物を載置するテーブルと地面に接する基台との間にＸ字形のリンク機構からなる持ち上げ機構を介在させた段差移動装置が開示されている。この段差移動装置では、テーブルに載置した重量物を段差の高い位置に持ち上げた後、テーブルの側辺に支持移動手段を取り付けて、基台を持ち上げ、重量物を載置したまま装置を高い位置に移動させるようになっている。 Patent Document 4 discloses a step moving device in which a lifting mechanism including an X-shaped link mechanism is interposed between a table on which a heavy object is placed and a base in contact with the ground. In this step moving device, after lifting a heavy object placed on the table to a position with a high step, a support moving means is attached to the side of the table, the base is lifted, and the device is raised with the heavy object placed on it. It is designed to move to a position.

しかし、特許文献１では、天井にジャッキを設置して重量物を吊り下げる構造であるため、図１０に示す工法と同様、天井の躯体の強度如何によって引き上げ時の落下の危険性が生じる。また、昇降ステージはレールを敷設するものであるため、実施場所に合わせた大きさに変更することは困難である。特許文献２では、仮受け材とレベル調整材の設置が煩雑で作業に時間がかかる。特許文献３では、門型のジャッキング装置が２台必要であるため作業が大がかりになり、また装置自体が大型であるため、実施現場によっては使用できない。特許文献４では、テーブルと基台がリンク機構で組み立てられているため、重量物の重量や大きさ、実施現場のスペースに合わせた構造の変更が困難であるうえ、テーブルの側辺への支持移動手段の着脱が煩雑で、作業に時間がかかるという問題がある。 However, since Patent Document 1 has a structure in which a heavy object is suspended by installing a jack on the ceiling, there is a risk of dropping when it is pulled up, depending on the strength of the ceiling casing as in the construction method shown in FIG. Moreover, since the elevating stage lays rails, it is difficult to change the size according to the place of implementation. In Patent Document 2, installation of the temporary support material and the level adjusting material is complicated and takes time. In Patent Document 3, since two gate-type jacking devices are required, the work becomes large, and since the device itself is large, it cannot be used depending on the implementation site. In Patent Document 4, since the table and the base are assembled by a link mechanism, it is difficult to change the structure in accordance with the weight and size of the heavy object and the space at the work site, and support to the side of the table is also provided. There is a problem that the moving means is complicated to attach and detach, and it takes time to work.

図１、図２、図３は、それぞれ本発明に係るジャッキ装置１の平面図、側面図、正面図である。ジャッキ装置１は、第１部材２と第２部材３からなる重量物を載置するための水平なステージ４と、該ステージ４を支持する４つの液圧シリンダ５（実施例では油圧シリンダ）からなる脚部６とからなり、油圧装置７により油圧シリンダ５を制御してステージ４を昇降するように構成されている。 1, 2, and 3 are a plan view, a side view, and a front view, respectively, of a jack device 1 according to the present invention. The jack apparatus 1 includes a horizontal stage 4 on which a heavy object composed of a first member 2 and a second member 3 is placed, and four hydraulic cylinders 5 (hydraulic cylinders in the embodiment) that support the stage 4. And the stage 4 is moved up and down by controlling the hydraulic cylinder 5 by the hydraulic device 7.

ステージ４の第１部材２は、２本の真直な形鋼からなり、好ましくは、図３に示すように、Ｈ２００またはＨ３００のＨ形鋼の両端に端板９とその内側にブラケット１０を溶接した山留め材である。第１部材２は、ジャッキ装置１の設置場所に合った長さの山留め材から選択することができる。２本の第１部材２は図１に示すように平行に配設される。 The first member 2 of the stage 4 is made of two straight sections. Preferably, as shown in FIG. 3, end plates 9 and brackets 10 are welded to both ends of an H section steel of H200 or H300. It is a mountain retaining material. The 1st member 2 can be selected from the mountain fastening material of the length suitable for the installation place of the jack apparatus 1. FIG. The two first members 2 are arranged in parallel as shown in FIG.

ステージ４の第２部材３は、少なくとも２本、好ましくは３本の真直な形鋼からなる。第２部材３は、好ましくは、図２に示すように、第１部材２と同様、Ｈ２００またはＨ３００のＨ形鋼の両端に端板１１とその内側にブラケット１２を溶接した山留め材である。第２部材３は、ジャッキ装置１の設置場所に合った長さの山留め材から選択することができる。第１部材２としてＨ２００の山留め材を使用するときは、第２部材３もＨ２００の山留め材を使用する。第１部材２としてＨ３００の山留め材を使用するときは、第２部材３もＨ３００の山留め材を使用するのが好ましいが、Ｈ２００の山留め部材でもよい。 The second member 3 of the stage 4 is made of at least two, preferably three straight sections. As shown in FIG. 2, the second member 3 is preferably a mountain fastening material in which end plates 11 and brackets 12 are welded to both ends of H-shaped steel of H200 or H300 as in the case of the first member 2. The 2nd member 3 can be selected from the mountain fastening material of the length suitable for the installation place of the jack apparatus 1. FIG. When an H200 mountain retaining material is used as the first member 2, the second member 3 also uses an H200 mountain retaining material. When an H300 mountain retaining material is used as the first member 2, it is preferable that the second member 3 also uses an H300 mountain retaining material, but an H200 mountain retaining member may also be used.

第２部材３は、図１に示すように、２本の第１部材２の間に第１部材２と垂直になるように配置される。第２部材３の両端は、連結部材１３を介して第１部材２に着脱可能に連結されている。連結部材１３は、図４、図５に示すように、鋼板からなる溶接構造を有し、第２部材３の幅とほぼ同じ幅を有する上部フランジ１４と、該上部フランジ１４の幅と同じ幅を有し上部フランジ１４より短い下部フランジ１５と、該下部フランジ１５と同じ幅を有し、下部フランジ１５の一端から斜めに立ち上がり水平に屈曲して上部フランジ１４と平行に延伸する下部屈曲フランジ１６と、上部フランジ１４と下部フランジ１５および下部屈曲フランジ１６を連結する逆Ｌ字形の平行な２つのウェブ１７と、上部フランジ１４の一端と下部フランジ１５の一端の間に設けられた基板１８と、上部フランジ１４の他端と下部屈曲フランジ１６の一端の間に設けられた端板１９と、下部屈曲フランジ１６の屈曲部１６ａと上部フランジ１４の間のウェブ１７に設けられたブラケット２０とを溶接により一体に形成したものである。連結部材１３は、全体的にみて、ブラケット２０より先端側の水平部１３ａと、ブラケット２０より基板１８側の垂直部１３ｂとで逆Ｌ字形を有している。垂直部１３ｂの下端すなわち下部フランジ１５の基板１８側の端部は、基板１８よりも水平に突出する突出部（コッタ）２１となっている。 As shown in FIG. 1, the second member 3 is disposed between the two first members 2 so as to be perpendicular to the first member 2. Both ends of the second member 3 are detachably connected to the first member 2 via a connecting member 13. As shown in FIGS. 4 and 5, the connecting member 13 has a welded structure made of a steel plate, and has an upper flange 14 having substantially the same width as that of the second member 3, and the same width as that of the upper flange 14. A lower flange 15 having a width shorter than that of the upper flange 14, a lower bent flange 16 having the same width as the lower flange 15, obliquely rising from one end of the lower flange 15, bending horizontally and extending parallel to the upper flange 14. Two inverted L-shaped webs 17 connecting the upper flange 14, the lower flange 15 and the lower bent flange 16, and a substrate 18 provided between one end of the upper flange 14 and one end of the lower flange 15, An end plate 19 provided between the other end of the upper flange 14 and one end of the lower bent flange 16, and a window between the bent portion 16 a of the lower bent flange 16 and the upper flange 14. It is obtained by integrally formed by welding a bracket 20 provided on the blanking 17. As a whole, the connecting member 13 has an inverted L shape with a horizontal portion 13 a on the tip side from the bracket 20 and a vertical portion 13 b on the substrate 18 side from the bracket 20. The lower end of the vertical portion 13 b, that is, the end portion on the substrate 18 side of the lower flange 15 is a protruding portion (cotter) 21 that protrudes more horizontally than the substrate 18.

連結部材１３の下部フランジ１５の突出部２１には、第２部材３の端板１１が載置されている。連結部材１３の垂直部１３ｂの基板１８は、第２部材３の端板１１にボルト・ナット２２により着脱可能に連結されている。連結部材１３の水平部１３ａは、第１部材２に載置され、連結部材１３の下部屈曲フランジ１６と座金２３とで第１部材２の上部両側縁を挟み、ボルト・ナット２４により第１部材２に着脱可能に連結されている。 The end plate 11 of the second member 3 is placed on the protruding portion 21 of the lower flange 15 of the connecting member 13. The substrate 18 of the vertical portion 13 b of the connecting member 13 is detachably connected to the end plate 11 of the second member 3 by bolts and nuts 22. The horizontal portion 13 a of the connecting member 13 is placed on the first member 2, the upper side edges of the first member 2 are sandwiched between the lower bent flange 16 and the washer 23 of the connecting member 13, and the first member is secured by bolts and nuts 24. 2 is detachably connected.

連結部材１３が逆Ｌ字形であるため、第２部材３を連結部材１３を介して第１部材２に連結した状態では、第２部材３の下面は第１部材２の上面より低くなっている。この結果、第１部材２と第２部材３を組み合わせたステージ４の厚さ（最少高さ）Ｈは、第１部材２より高いが、第１部材２と第２部材３の合計高さより低くすることができる。第１部材２及び第２部材３としてＨ２００の山留め材を使用した場合は、ステージ４の厚さは２８０ｍｍ、Ｈ３００の山留め材を使用した場合は、ステージ４の厚さは３８０ｍｍとすることが好ましい。連結部材１３の垂直部１３ｂの下部フランジ１５を第１部材２の下部フランジ１５と同じ位置まで下げることで、ステージ４の厚さを第１部材２とほぼ同じにすることもできる。 Since the connecting member 13 has an inverted L shape, the lower surface of the second member 3 is lower than the upper surface of the first member 2 when the second member 3 is connected to the first member 2 via the connecting member 13. . As a result, the thickness (minimum height) H of the stage 4 in which the first member 2 and the second member 3 are combined is higher than that of the first member 2 but lower than the total height of the first member 2 and the second member 3. can do. When the H200 mountain retaining material is used as the first member 2 and the second member 3, the stage 4 thickness is preferably 280 mm, and when the H300 mountain retaining material is used, the stage 4 thickness is preferably 380 mm. . The thickness of the stage 4 can be made substantially the same as that of the first member 2 by lowering the lower flange 15 of the vertical portion 13 b of the connecting member 13 to the same position as the lower flange 15 of the first member 2.

油圧シリンダ５からなる脚部６は、ロッド２５の先端が土台に設置されるように土台に垂直に配置されている。図６（ａ）、（ｂ）に示すように、油圧シリンダ５のシリンダ本体２６の下端には、脚部６の支持台２７が取り付けられている。支持台２７は、シリンダ本体２６の端フランジ２８にボルト・ナット２９で固着された上板３０と、該上板３０に垂直に溶接接合された基板３１と、基板３１の両側端に溶接接合された側板３２と、基板３１の下端に溶接接合された下板３３とで箱形に形成されている。基板３１の上部には、三角形のガイド３４が側板３２と反対側に突出している。下板３３の基板３１側の端部は、基板３１よりも水平に突出する突出部（コッタ）３５となっている。両側の側板３２には、コ字形のブラケット３６がボルト・ナット３７により取り付けられ、該ブラケット３７に２つのキャスタ３８が取り付けられている。 The leg 6 composed of the hydraulic cylinder 5 is arranged perpendicular to the base such that the tip of the rod 25 is placed on the base.
