GRIPPING MECHANISM OF SHAFT CONSTRUCTION MACHINE AND SHAFT CONSTRUCTION MACHINE
To provide a gripping mechanism of a shaft construction machine and a shaft construction machine that maintains sufficient strength of split portions even when assembled and used, and allows safe shaft construction.SOLUTION: A gripping mechanism 10 of a shaft construction machine comprises an arcuate bearing piece divided into a plurality of pieces, each of which is connected at both ends to form an annular geared bearing 11, an arcuate bearing mounting seat piece divided into a plurality of pieces, each of which is connected at both ends to form an annular bearing mounting seat 12, and to which the geared bearing 11 is fixed, and a fixed band member 131 that is a band member 13 that grips a cylindrical member, and that is fixed to the bearing mounting seat 12. At least one arcuate bearing mounting seat piece among the plurality of divided arcuate bearing seat pieces is fixed across at least one of the connection surfaces between the plurality of divided arcuate bearing pieces.SELECTED DRAWING: Figure 5
【課題】組み立てて使用する際も分割部分の強度が十分に保たれ、安全に立坑工事を行うことができる立坑構築機の把持機構および立坑構築機の提供。【解決手段】立坑構築機の把持機構１０は、それぞれの両端部を各々接続して環状の歯車付ベアリング１１を構成する複数に分割された円弧状ベアリング片と、それぞれの両端部を各々接続して環状のベアリング取付座１２を構成する複数に分割された円弧状ベアリング取付座片であり、歯車付ベアリング１１が固定される円弧状ベアリング取付座片と、円筒状部材を把持するバンド部材１３であり、ベアリング取付座１２に固定される固定バンド部材１３１とを備え、複数に分割された円弧状ベアリング取付座片のうちの少なくとも一つの円弧状ベアリング取付座片は、複数に分割された円弧状ベアリング片同士の接続面のうちの少なくとも一つの接続面を跨いで固定される。【選択図】図５
