The invention discloses a mechanical grabbing and lifting head, a mechanical grabbing and lifting head type segment crane and a grabbing method of the mechanical grabbing and lifting head type segment crane. The mechanical grabbing and lifting head comprises a box body structure, at least two clamping jaws are hinged to the box body structure, the clamping jaws are opened when colliding with a hoisting bolt, and the clamping jaws grab an end cover of the hoisting bolt under the action of self weight after being opened; or the clamping jaw is driven by the telescopic mechanism to grab and release the end cover of the hoisting bolt; the mechanical grabbing and lifting head type segment crane uses the mechanical grabbing and lifting head. The problem that in the prior art, a mechanical grabbing and lifting head type segment crane cannot automatically grab segments is solved, manual operation is reduced, and safety risks are reduced. A technical foundation is laid for a conventional shield mechanical segment crane to automatically grab segments, and then shield intellectualization is achieved by being used in cooperation with other electrical equipment.
本发明公开了一种机械抓举头、机械抓举头式管片吊机及其抓取方法,所述机械抓举头包括箱体结构,箱体结构铰接有至少两个卡爪,卡爪与起吊螺栓碰撞时张开,卡爪张开后在自重作用下抓取起吊螺栓的端盖;或者卡爪在伸缩机构的驱动下抓取及释放起吊螺栓的端盖;所述机械抓举头式管片吊机使用所述机械抓举头。本发明解决了现有技术中机械抓举头式管片吊机不能自动抓取管片的问题,减少了人工操作,降低了安全风险。本发明为常规盾构机械式管片吊机自动抓取管片打下了技术基础,进而与其他电气设备配套配合使用实现盾构智能化。
