Description

【0001】
【発明の属する技術分野】
本発明は、インゴット,ロケット等の大型重量物の設置に係る技術分野に属する。
【0002】
【従来の技術】
一般に、大型重量物は、専用の搬送架台に固定的に支持されて搭載される。大型重量物を搭載した搬送架台は、大型の搬送車両に持ち上げられて搬送される。大型重量物(搬送架台)の設置位置では、搬送車両による搬送架台の持ち上げを解除し搬送架台を降下させて据え付けている。
【0003】
従来、大型重量物の設置技術としては、例えば、図7に示すものが知られている。
【0004】
この従来の大型重量物の設置技術は、大型重量物Pを搭載した門形の搬送架台1の桁部1aを2台の搬送車両2で持ち上げて搬送する。設置位置には、搬送架台1の据え付けの基準となる円錐台形の突起からなる目標物3が設置されている。また、搬送架台1の脚部1bの下端面には、目標物3に対応した円錐台形の溝からなる位置決め手段4が設けられている。
【0005】
この従来の大型重量物の設置技術では、設置位置に到達した搬送車両2の微調整が可能なステアリングによって、目標物3の軸線Xと位置決め手段4の軸線Yとを一致させた後、搬送車両2による搬送架台1の持ち上げを解除し搬送車両2の車高を下げることで搬送架台1を降下させて据え付けている。このとき、目標物3の軸線Xと位置決め手段4の軸線Yとの間にずれSがある場合には、降下する位置決め手段4の円錐台形のテーパを目標物3の円錐台形のテーパで滑らせ、最終的に位置決め手段4の円錐台形と目標物3の円錐台形とを緊密に嵌合させて搬送架台1の据付精度を確保している。即ち、搬送架台1の据え付けのための降下と、設置位置の目標物3に対する搬送架台2の位置の補正とを同時に進行させている。
【0006】
【発明が解決しようとする課題】
前述の従来の大型重量物の設置技術では、降下する位置決め手段4の円錐台形のテーパを目標物3の円錐台形のテーパで滑らせる際に、大型重量物P,搬送架台1の荷重で目標物3,位置決め手段4を損傷してしまい、位置決め手段4の円錐台形と目標物3の円錐台形との緊密な嵌合が得られるなくなることがある。このため、搬送架台1の高度な据付精度を期待することができないという問題点がある。また、目標物3と位置決め手段4の強度を上げれば、搬送架台と搬送台車との接触面を無理矢理滑らせることになり接触面を破損させる。更にはその際の振動などで大型重量物が傾いたり揺れたりするという問題が発生する。
【0007】
本発明は、このような問題点を考慮してなされたもので、大型重量物を搭載した搬送架台を設置位置に高精度に据え付けることのできる大型重量物の設置方法と、この大型重量物の設置方法を実施する好適な大型重量物の設置装置とを提供することを課題とする。
【0008】
【課題を解決するための手段】
前述の課題を解決するため、本発明に係る大型重量物の設置方法は、次のような手段を採用する。
【0009】
即ち、請求項1に記載のように、大型重量物が搭載された搬送架台を搬送車両との相対移動を拘束した状態で持ち上げて搬送し、設置位置で搬送車両による搬送架台の持ち上げを解除して搬送架台を据え付ける際に、設置位置に設けられた据え付けの基準となる少なくとも2箇所の目標物に対する搬送架台の位置を補正する大型重量物の設置方法において、設置位置付近で搬送架台を持ち上げた状態で搬送車両を停止させ、搬送架台の少なくとも2箇所に設けられた案内機構により、それぞれ対応する目標物に対する距離と角度を計測しつつ搬送架台と搬送車両の間に介装され搬送架台と搬送車両の拘束を解除して相対移動を可能にするスライド機構により搬送架台を搬送車両上でスライドさせながら、案内機構に予め記憶させておいたそれぞれの目標物に対する正規の設置位置における距離と角度となるように搬送架台の位置を補正する動作と、搬送車両による搬送架台の持ち上げを解除する動作とを同時におこなわせて、搬送架台を正規の設置位置に精度良く据え付けることを特徴とする。
【0010】
この手段では、設置位置で搬送車両による搬送架台の持ち上げを解除する際、案内機構とスライド機構による搬送架台の位置を補正する動作と、搬送車両による搬送架台の持ち上げを解除する動作とを連動させるため、位置決め手段である案内機構の破損、搬送車両と搬送架台の接触面の破損といった問題は生じない。
【0011】
さらに、前述の課題を解決するため、本発明に係る大型重量物の設置装置は、次のような手段を採用する。
【0012】
即ち、請求項2に記載のように、大型重量物が搭載される搬送架台と、搬送架台の持ち上げ,持ち上げ解除が可能で搬送架台との相対移動を拘束した状態で持ち上げて搬送する搬送車両と、設置位置に設けられ搬送架台の据え付けの基準となる少なくとも2箇所の目標物とを備えた大型重量物の設置装置において、搬送架台と搬送車両の間に介装され搬送架台と搬送車両の拘束を解除して相対移動を可能にするスライド機構と、それぞれの目標物に対する距離と角度を計測しつつ搬送架台をスライド機構によりスライドさせながらそれぞれの目標物に対する正規の設置位置における距離と角度となるように案内する搬送架台の少なくとも2箇所に設けられた予め正規の設置位置における距離と角度を記憶させた案内機構とを備え、案内機構とスライド機構による搬送架台の位置を補正する動作と、搬送車両による搬送架台の持ち上げを解除する動作とを同時におこなわせて、搬送架台を正規の設置位置に精度良く据え付けるようにしたことを特徴とする。
【0013】
この手段では、スライド機構,案内機構によって搬送車両上で搬送架台をスライドさせて設置位置の目標物に対する搬送架台の位置を補正する。この時、案内機構とスライド機構による搬送架台の位置を補正する動作と、搬送車両による搬送架台の持ち上げを解除する動作とを連動させるため前述の方法と同様位置決め手段である案内機構の破損、搬送車両と搬送架台の接触面の破損といった問題は生じない。
【0014】
また、請求項3に記載のように、請求項2の大型重量物の設置装置において、スライド機構は搬送架台をスライド駆動可能であることを特徴とする。
【0015】
この手段では、スライド機構自体がスライド駆動力を備える。
【0016】
また、請求項4では、請求項2または3の大型重量物の設置装置において、スライド機構は空気圧力で搬送架台,搬送車両の一方との摩擦を減少させるものであることを特徴とする。
【0017】
この手段では、空気圧力による摩擦の減少でスライドが可能になる。
【0018】
【発明の実施の形態】
以下、本発明に係る大型重量物の設置方法および設置装置の実施の形態を図1〜図6に基づいて説明する。
【0019】
図1〜図5は、本発明に係る大型重量物の設置方法および設置装置の実施の形態(1)を示すものである。
【0020】
この実施の形態は、前述の従来例と同様の大型重量物P、門形の搬送架台1、2台の搬送車両2からなる構成を採用している。
【0021】
この実施の形態の目標物3は、設置面に堀込まれた丸孔形の軸孔からなる。
【0022】
さらに、この実施の形態は、前述の従来例の位置決め機構4を案内機構5に代替えしている。案内機構5は、搬送架台1の側部に収容,取出し可能に設けられてなるもので、搬送架台1に伸縮,回転可能支持されたアーム5aと、アーム5aに支持され目標物3に嵌合されるシャフト5bとを備えている。アーム5aは、シャフト5bを軸方向へスライド可能に支持している。
【0023】
さらに、この実施の形態は、スライド機構6を追加している。スライド機構6は、搬送架台1,搬送車両2の間に介装され搬送車両2側に固定されてなるもので、空気圧力で搬送架台1,搬送車両2の一方との摩擦を減少させ、搬送車両2上で搬送架台1のスライド移動を可能にする。このスライド機構6は、エアキャスタ等と称せられ、空気の供給形態によって搬送架台1との摩擦を適当部分で減少させ、搬送架台1をスライド駆動することができるようになっている。従って、スライド駆動のための機構を別個に備える必要がなく、スライド機6構周りの構造が簡素化される。
【0024】
この実施の形態によると、案内機構5,スライド機構6を既存装置に追加することで構成することができるため、既存装置について容易に改造実施することができる。
【0025】
この実施の形態を使用するには、図1(A)、(B)に示すように、設置位置付近までは大型重量物Pを搭載した搬送架台1の桁部1aを2台の搬送車両で持ち上げて搬送する。
【0026】
搬送車両2が設置位置付近に到達したならば、目標物3を基準にした搬送車両2の微調整が可能なステアリングによって、搬送架台1を正規の位置に近づける。この後、搬送車両2は、その位置で停止される。
【0027】
続いて、図2(A)に示すように、搬送架台1から案内機構5を取出し、案内機構5のアーム5aを伸張させシャフト5bを目標物3に嵌合して立設する。このとき、案内機構5のアーム5aの伸張長a,bに微小な差がある。なお、搬送時と同様に、搬送架台1の搬送車両2による持ち上げは維持されている。
【0028】
続いて、スライド機構6を駆動させる。スライド機構6は、図2(B)に示すように、空気圧力で搬送架台1を持ち上げるようにして、搬送架台1との摩擦を減少させ、容易,円滑なスライドを可能な状態にしている。この状態では、案内機構5により搬送架台は支持されているため、搬送架台1にわずかな傾きがあった場合あるいは横風などを受けた場合でも搬送車両に対して滑り出すことはない。その後、案内機構5を作動させ、搬送架台1をスライド駆動する。このとき、図5に示すように、案内機構5は搬送架台1の正規の位置における案内機構5のアーム5aの伸張長cと角度θとを予め記憶しており、この伸張長c,角度θとなるように搬送架台1のスライドを誘導する。この結果、案内機構5のアーム5aの伸張長a,bの微小な差を吸収して、搬送架台1は正規の位置に合致するように動く。なお、案内機構5の詳細な構成については特に説明しないが記憶手段やアーム等の駆動を制御する制御手段等の案内機構の作動に必要な構成を備えていることは言うまでもない。
【0029】
続いて、図3(A)に示すように、案内機構5、スライド機構6を作動させた状態で搬送架台の持ち上げを解除する。この時、搬送車両2の車高を下げる過程で横ズレを生じても、搬送架台1は案内機構5、スライド機構6の作動により正規の位置に対し精密に設置される。
【0030】
続いて、図3(C)に示すように、搬送車両2の車高をさらに下げるとともに、スライド機構6の作動を停止する。同時に案内機構5の作動も停止する。この結果、搬送架台1は、設置位置の正規の位置に精密に据え付けられることになる。
【0031】
即ち、この実施の形態では、搬送車両2上で搬送架台1をスライドさせて設置位置の目標物3に対する搬送架台1の位置を補正しながら、搬送車両2による搬送架台1の持ち上げを解除して搬送架台1を据え付けるため、目標物3等を損傷することがなく、大型重量物Pを搭載した搬送架台1を設置位置に素早くに据え付けることができる。
【0032】
図6は、本発明に係る大型重量物の設置方法および設置装置の実施の形態(2)を示すものである。
【0033】
この実施の形態では、案内機構5が光学的手段等によって目標物3を捕捉して距離,角度等を計測するものによって構成される。この案内機構5を用いる場合にはスライド機構6として案内機構5からの指示により搬送架台1をスライド駆動できるものを用いる。
【0034】
この実施の形態によると、前述の実施の形態(1)のような目標物3,案内機構5の機械的結合が回避されるため、搬送架台1の位置の補正を高速に実行することができる。
【0035】
以上、図示した実施の形態の外に、門形以外の搬送架台1に適用することも可能である。
【0036】
さらに、案内機構5のシャフト5bと目標物3とを円錐台形の嵌合構造とすることも可能である。
【0037】
さらに、案内機構5をローラ等の機械的転動構造とすることも可能である。
【0038】
【発明の効果】
以上のように、本発明によれば、大型重量物を搭載した搬送架台を搬送台車で担ぎ上げて所定位置まで運搬して据え付ける(持ち上げを解除する)際に、搬送車両による搬送架台の持ち上げを解除する(据え付ける)動作をスライド機構により据付位置(水平位置)のズレを補正する動作を同時に行わせるため、いわゆる一発動作で搬送架台を精度良く設置することができる。
【0039】
また、本発明に係る大型重量物の設置装置は、前述の本発明に係る大型重量物の設置方法の効果を損なわずに実施することができることに加えて、スライド機構,案内機構によって搬送車両上で搬送架台をスライドさせて設置位置の目標物に対する搬送架台の位置を補正するため、案内機構,スライド機構を既存装置に追加するだけで、既存装置を容易に改造実施することができる効果がある。
【0040】
また、請求項3として、スライド機構自体がスライド駆動力を備えるため、案内機構に駆動力がなくてもスライド駆動のための機構を別個に備える必要がなく、スライド機構周りの構造が簡素化される効果がある。
【0041】
また、請求項4として、空気圧力による摩擦の減少で搬送架台,搬送車両を相対的にスライドさせるため、容易,円滑なスライドが可能になる効果がある。

BACKGROUND OF THE INVENTION
The present invention belongs to a technical field related to installation of large heavy objects such as ingots and rockets.
[0002]
[Prior art]
In general, large heavy objects are fixedly supported and mounted on a dedicated conveyance platform. A transport platform carrying a large heavy object is lifted and transported by a large transport vehicle. At the installation position of the large heavy object (conveyance platform), the lifting of the conveyance platform by the conveyance vehicle is released and the conveyance platform is lowered and installed.
[0003]
Conventionally, as an installation technique of a large heavy object, for example, the one shown in FIG. 7 is known.
[0004]
In this conventional technology for installing large heavy objects, the girder portion 1a of the gate-shaped conveyance platform 1 on which the large heavy objects P are mounted is lifted by two conveyance vehicles 2 and conveyed. At the installation position, a target 3 made of a frustoconical protrusion serving as a reference for installation of the transport frame 1 is installed. In addition, a positioning means 4 including a truncated cone-shaped groove corresponding to the target 3 is provided on the lower end surface of the leg portion 1 b of the transport frame 1.
[0005]
In this conventional technology for installing a large heavy object, after the axis X of the target 3 and the axis Y of the positioning means 4 are made to coincide with each other by steering capable of fine adjustment of the transport vehicle 2 that has reached the installation position, the transport vehicle The lift of the transport stand 1 by 2 is released and the height of the transport vehicle 2 is lowered, so that the transport stand 1 is lowered and installed. At this time, if there is a deviation S between the axis X of the target 3 and the axis Y of the positioning means 4, the frustoconical taper of the descending positioning means 4 is slid by the frustoconical taper of the target 3. Finally, the frustoconical shape of the positioning means 4 and the frustoconical shape of the target 3 are tightly fitted to ensure the installation accuracy of the transport frame 1. That is, the lowering for installation of the transportation platform 1 and the correction of the position of the transportation platform 2 with respect to the target 3 at the installation position are simultaneously performed.
[0006]
[Problems to be solved by the invention]
In the above-described conventional technology for installing large heavy objects, when the truncated cone taper of the descending positioning means 4 is slid with the truncated cone taper of the target object 3, the target object is loaded with the large heavy object P and the load of the transport platform 1. 3. The positioning means 4 may be damaged, and a close fitting between the truncated cone shape of the positioning means 4 and the truncated cone shape of the target 3 may not be obtained. For this reason, there exists a problem that the high installation precision of the conveyance mount frame 1 cannot be expected. Further, if the strength of the target 3 and the positioning means 4 is increased, the contact surface between the transport gantry and the transport cart is forcibly slid to damage the contact surface. Furthermore, there is a problem that a large heavy object is tilted or shakes due to vibration at that time.
[0007]
The present invention has been made in consideration of such problems, and a method for installing a large heavy load that can highly accurately install a transportation platform carrying a large heavy load at an installation position, and It is an object of the present invention to provide a suitable installation device for a large heavy object that implements the installation method.
[0008]
[Means for Solving the Problems]
In order to solve the above-described problems, the following method is employed in the method for installing a large heavy object according to the present invention.
[0009]
That is, as described in claim 1, the transport platform on which a large heavy object is mounted is lifted and transported in a state in which the relative movement with the transport vehicle is restricted, and the lift of the transport platform by the transport vehicle is released at the installation position. When installing the transport platform, the transport platform was lifted in the vicinity of the installation position in the large heavy load installation method that corrects the position of the transport platform relative to at least two targets that are the reference for installation at the installation position. the transfer vehicle is stopped in the state, more guide mechanism provided on at least two positions of the conveying platform, and each interposed between corresponding to the transport platform while measuring the distance and angle to the target transport vehicle conveying platform It is stored in the guide mechanism in advance while sliding the transport frame on the transport vehicle by the slide mechanism that releases the restraint of the transport vehicle and enables relative movement. Les operation and for correcting the position of the transfer platform such that the distance and angles in the normal installation position relative to the target of, by performed the operation for releasing the lifting of the transport frame by the transport vehicle at the same time, the conveying platform of the normal It is characterized by being accurately installed at the installation position.
[0010]
In this means, when releasing the lifting of the transportation platform by the transportation vehicle at the installation position, the operation of correcting the position of the transportation platform by the guide mechanism and the slide mechanism and the operation of releasing the lifting of the transportation platform by the transportation vehicle are linked. Therefore, problems such as breakage of the guide mechanism serving as positioning means and breakage of the contact surface between the transport vehicle and the transport frame do not occur.
[0011]
Furthermore, in order to solve the above-described problems, the large-sized heavy load installation apparatus according to the present invention employs the following means.
[0012]
That is, as described in claim 2, a transport platform on which a large heavy object is mounted, and a transport vehicle that lifts and transports the transport platform in a state in which the transport platform can be lifted and released and the relative movement with the transport platform is restricted. In a heavy-duty heavy equipment installation device provided with at least two targets that are provided at the installation position and serve as a reference for installation of the transportation platform, the restraint between the transportation platform and the transportation vehicle is interposed between the transportation platform and the transportation vehicle. The slide mechanism that enables the relative movement by releasing and the distance and angle at the normal installation position with respect to each target while sliding the transport platform by the slide mechanism while measuring the distance and angle with respect to each target and a guide guiding mechanism stores the distance and angles in the previously normal installation position provided on at least two positions of the conveying platform of such a guide mechanism Operation for correcting the position of the transport platform by Ride mechanism, by performed the operation for releasing the lifting of the transport frame by the transport vehicle at the same time, characterized in that as install accurately conveying platform in the installation position of the normal .
[0013]
In this means, the position of the transport platform relative to the target at the installation position is corrected by sliding the transport platform on the transport vehicle by the slide mechanism and the guide mechanism. At this time, in order to link the operation of correcting the position of the conveyance platform by the guide mechanism and the slide mechanism with the operation of releasing the lifting of the conveyance platform by the conveyance vehicle, the guide mechanism is broken or conveyed in the same manner as described above. There is no problem of damage to the contact surface between the vehicle and the carriage.
[0014]
According to a third aspect of the present invention, in the apparatus for installing a large heavy object according to the second aspect, the slide mechanism is capable of slidably driving the conveyance platform.
[0015]
In this means, the slide mechanism itself has a slide driving force.
[0016]
According to a fourth aspect of the present invention, in the apparatus for installing a large heavy object according to the second or third aspect, the slide mechanism reduces the friction with one of the transport gantry and the transport vehicle by air pressure.
[0017]
With this means, sliding is possible by reducing friction due to air pressure.
[0018]
DETAILED DESCRIPTION OF THE INVENTION
DESCRIPTION OF EMBODIMENTS Hereinafter, embodiments of a large-sized heavy load installation method and installation apparatus according to the present invention will be described with reference to FIGS.
[0019]
FIGS. 1-5 shows Embodiment (1) of the installation method and installation apparatus of the large sized heavy article which concern on this invention.
[0020]
This embodiment employs a configuration composed of a large heavy object P, a portal-shaped transport base 1, and two transport vehicles 2 similar to the conventional example described above.
[0021]
The target 3 in this embodiment is a round hole shaft hole dug into the installation surface.
[0022]
Further, in this embodiment, the above-described conventional positioning mechanism 4 is replaced with a guide mechanism 5. The guide mechanism 5 is provided so as to be housed and taken out from the side of the transport frame 1. The guide mechanism 5 is supported by the arm 5 a that can be expanded, contracted and rotated on the transport frame 1, and is fitted to the target 3 supported by the arm 5 a. Shaft 5b. The arm 5a supports the shaft 5b so as to be slidable in the axial direction.
[0023]
Further, in this embodiment, a slide mechanism 6 is added. The slide mechanism 6 is interposed between the transport platform 1 and the transport vehicle 2 and is fixed to the transport vehicle 2 side. The slide mechanism 6 reduces friction with one of the transport platform 1 and the transport vehicle 2 by air pressure, The sliding movement of the carrier base 1 is made possible on the vehicle 2. The slide mechanism 6 is referred to as an air caster or the like, and can reduce the friction with the carrier base 1 at an appropriate portion depending on the air supply mode, and can slide the carrier base 1. Therefore, it is not necessary to separately provide a mechanism for driving the slide, and the structure around the six slide machines is simplified.
[0024]
According to this embodiment, since the guide mechanism 5 and the slide mechanism 6 can be added to the existing device, the existing device can be easily modified.
[0025]
In order to use this embodiment, as shown in FIGS. 1 (A) and 1 (B), the girder portion 1a of the carrier base 1 on which the large heavy object P is mounted is used by two carrier vehicles up to the vicinity of the installation position. Lift and transport.
[0026]
When the transport vehicle 2 reaches the vicinity of the installation position, the transport base 1 is brought close to the normal position by the steering capable of fine adjustment of the transport vehicle 2 with the target 3 as a reference. Thereafter, the transport vehicle 2 is stopped at that position.
[0027]
Subsequently, as shown in FIG. 2 (A), the guide mechanism 5 is taken out from the carrier base 1, the arm 5a of the guide mechanism 5 is extended, and the shaft 5b is fitted to the target 3 to stand. At this time, there is a slight difference in the extension lengths a and b of the arm 5a of the guide mechanism 5. In addition, the lift by the conveyance vehicle 2 of the conveyance mount frame 1 is maintained similarly to the time of conveyance.
[0028]
Subsequently, the slide mechanism 6 is driven. As shown in FIG. 2 (B), the slide mechanism 6 lifts the carrier base 1 with air pressure to reduce friction with the carrier base 1 so that it can slide easily and smoothly. In this state, since the transport frame is supported by the guide mechanism 5, even if the transport frame 1 is slightly tilted or receives a crosswind, it does not slide out relative to the transport vehicle. Thereafter, the guide mechanism 5 is operated, and the transport frame 1 is slid. At this time, as shown in FIG. 5, the guide mechanism 5 stores in advance the extension length c and the angle θ of the arm 5 a of the guide mechanism 5 at the normal position of the transport frame 1. The slide of the conveyance platform 1 is guided so that As a result, a minute difference between the extension lengths a and b of the arm 5a of the guide mechanism 5 is absorbed, and the transport frame 1 moves so as to match the normal position. Although the detailed configuration of the guide mechanism 5 is not particularly described, it is needless to say that the guide mechanism 5 has a configuration necessary for the operation of a guide mechanism such as a control unit that controls driving of a storage unit, an arm, and the like.
[0029]
Subsequently, as shown in FIG. 3A, the lifting of the conveyance platform is released in a state where the guide mechanism 5 and the slide mechanism 6 are operated. At this time, even if a lateral shift occurs in the process of lowering the height of the transport vehicle 2, the transport mount 1 is precisely installed with respect to the normal position by the operation of the guide mechanism 5 and the slide mechanism 6.
[0030]
Subsequently, as shown in FIG. 3C, the height of the transport vehicle 2 is further lowered and the operation of the slide mechanism 6 is stopped. At the same time, the operation of the guide mechanism 5 is also stopped. As a result, the transport stand 1 is precisely installed at a regular position of the installation position.
[0031]
That is, in this embodiment, while lifting the transportation platform 1 on the transportation vehicle 2 to correct the position of the transportation platform 1 relative to the target 3 at the installation position, the lifting of the transportation platform 1 by the transportation vehicle 2 is canceled. Since the transport platform 1 is installed, the target platform 3 and the like are not damaged, and the transport platform 1 loaded with the large heavy object P can be quickly installed at the installation position.
[0032]
FIG. 6 shows an embodiment (2) of the method and apparatus for installing a large heavy object according to the present invention.
[0033]
In this embodiment, the guide mechanism 5 is configured to capture the target 3 by optical means or the like and measure the distance, angle, and the like. When this guide mechanism 5 is used, a slide mechanism 6 that can slide-drive the conveyance platform 1 according to an instruction from the guide mechanism 5 is used.
[0034]
According to this embodiment, since the mechanical connection of the target 3 and the guide mechanism 5 as in the above-described embodiment (1) is avoided, the position of the transport platform 1 can be corrected at high speed. .
[0035]
As described above, in addition to the illustrated embodiment, the present invention can be applied to the transport platform 1 other than the portal shape.
[0036]
Furthermore, the shaft 5b of the guide mechanism 5 and the target 3 can be formed into a frustoconical fitting structure.
[0037]
Furthermore, the guide mechanism 5 can be a mechanical rolling structure such as a roller.
[0038]
【The invention's effect】
As described above , according to the present invention , when a transport platform carrying a large heavy load is lifted by the transport cart and transported to a predetermined position and installed (release is lifted), the transport platform is lifted by the transport vehicle. Since the release (installation) operation is simultaneously performed by the slide mechanism to correct the displacement of the installation position (horizontal position), the transport frame can be accurately installed by a so-called single operation.
[0039]
In addition, the large heavy load installation device according to the present invention can be implemented without impairing the effects of the large heavy load installation method according to the present invention described above. In order to correct the position of the transportation platform relative to the target at the installation position by sliding the transportation platform, the existing device can be easily modified simply by adding a guide mechanism and slide mechanism to the existing device. .
[0040]
Further, according to the third aspect, since the slide mechanism itself has a slide drive force, it is not necessary to provide a separate slide drive mechanism even if the guide mechanism has no drive force, and the structure around the slide mechanism is simplified. There is an effect.
[0041]
Further, as claimed in claim 4, since the transport frame and the transport vehicle are slid relative to each other due to the reduction of the friction due to the air pressure, there is an effect of enabling easy and smooth sliding.
