The invention discloses a shaft segment hoisting and anti-twisting device. The shaft segment hoisting and anti-twisting device comprises a fixing frame used for fixedly connecting with a shaft segmenthoisting installing base and a limiting frame connected with the fixing frame, wherein a limiting groove used for cooperating with a sliding block on a segment ring to prevent torsion of the whole segment ring and at least two guide wheels for clearance fit with the outer side wall of the segment ring to position and guide the whole segment ring. According to the shaft segment hoisting and anti-twisting device, the outer side wall of the segment ring is positioned and guided by the guide wheels, so that the centering degree of the segment ring is guaranteed and the sliding block slides into the limiting groove more smoothly, after the sliding block is clamped into the limiting groove, the limiting groove plays a limiting role on the segment ring, and the segment ring is prevented from rotating in the circumferential direction, so that the whole segment ring is prevented from being twisted and loaded, and the like. The invention further discloses a shaft segment hoisting and anti-twisting system comprising the shaft segment hoisting and anti-twisting device.
本发明公开了一种竖井管片吊装防扭装置,包括:用于与竖井管片吊装安装座固定连接的固定架;与固定架相连的限位架,限位架设有:用于与管片环上的滑块凹凸配合以防止整个管片环扭转的限位槽;用于与管片环的外侧壁间隙配合以对整个管片环进行定位和导向的至少两个导向轮。该竖井管片吊装防扭装置通过导向轮对管片环的外侧壁进行定位和导向,以保证管片环的对中度,并使滑块更顺畅地滑入限位槽内,滑块卡入限位槽内后,限位槽对管片环起到限位作用,防止管片环周向转动,从而可以防止整个管片环扭转及偏载等。本发明还公开了一种包括上述竖井管片吊装防扭装置的竖井管片吊装防扭系统。
