POSITION ADJUSTMENT SYSTEM AND POSITION ADJUSTMENT METHOD FOR HEAVY OBJECT

To provide a position adjustment technique for a long heavy object that can be used in a narrow place, is excellent in portability, and can be remotely operated.SOLUTION: A position adjustment system for a heavy object includes: a plurality of position adjustment devices that are disposed at support points of a long heavy object and are capable of three-dimensional position adjustment; a centralized control device that synchronously controls the position adjustment devices; and communication means that connects them. Each of the position adjustment devices has: two placement tables that are rectangular in shape in a plan view, placed in two tiers on an installation surface, and have upper surface plates translatable in different directions in a horizontal plane; a hydraulic vertical jack that is installed on the placement tables and lifts and lowers the heavy object; and a sensor group. Each placement table includes: a horizontal base; a plurality of cylindrical rollers that are arranged on the horizontal base so as to be translatable; a horizontal jack that is assembled to one of the horizontal base and the upper surface plate and is capable of applying a reciprocating force to the other in a horizontal direction; and an upper surface plate in which movement in a direction orthogonal to the translation is restricted and that is placed on the rollers. The centralized control device is configured to synchronously control the position adjustment devices via the communication means on the basis of information obtained from the sensor group via the communication means.SELECTED DRAWING: Figure 1 【課題】狭隘箇所で使用でき、可搬性に優れ、遠隔操作可能な長尺重量物の位置調整技術を提供する。【解決手段】長尺重量物の支持点に複数配置され、３次元位置調整可能な位置調整装置と、同期制御するための集中制御機器と、それらを連結する通信手段と、を備え、位置調整装置は、平面視矩形状で、設置面に二段重ねで載置され、上面板が水平面内の異なる方向に並進可能な二基の載置台と、載置台上に据え付けられ、重量物を扛上・下降する油圧式の鉛直ジャッキと、センサ群と、を有し、載置台は、水平基台と、その上に並進可能に配列された複数の円柱状転動子と、前記水平基台および上面板のいずれか一方に組付けられ、他方を水平方向に往復加力可能な水平ジャッキと、並進と直交する方向への運動を規制され、転動子上に載置された上面板と、を、持ち、集中制御機器は、通信手段を介してセンサ群から得られた情報に基づいて、通信手段を介して位置調整装置を同期制御するように構成されている、システムである。【選択図】図１
