The invention discloses a shaft segment hoisting anti-twisting device. The shaft segment hoisting anti-twisting device comprises a fixing frame used for fixed connection with a shaft segment hoistinginstallation seat and a limiting frame connected with the fixing frame, and a limiting groove used for being in concave-convex matching with a siding block on a segment ring to prevent the entire segment ring from twisting and at least two guide wheels used for being in clearance fit with the outer side wall of the segment ring to position and guide the entire segment ring. According to the shaftsegment hoisting anti-twisting device, the outer side wall of the segment ring is positioned and guided through the guide wheels so as to ensure the centring degree of the segment ring, 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 to prevent the segmentring from rotating in the circumferential direction, and the entire segment ring is prevented from twisting and eccentric loading. The invention further discloses a shaft segment hoisting anti-twisting system including the shaft segment hoisting 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。
