The invention relates to the technical field of pipe piece lifting appliances for tunneling, in particular to a pipe piece lifting appliance which comprises a lifting beam, lifting points used for being connected with lifting hooks of a crane are arranged at the two ends of the lifting beam, a rotating shaft is rotationally assembled in the middle of the lifting beam, and a mounting hole used for mounting the rotating shaft is formed in the lifting beam. A driving mechanism which is in transmission connection with the rotating shaft to drive the rotating shaft to rotate is installed on the hanging beam, the rotating shaft comprises a rotating rod with the axis extending in the vertical direction, and a grabbing head which is used for penetrating through an insertion opening in a duct piece to stretch into a grabbing cavity of the duct piece and rotating is arranged at the lower end of the rotating rod; the grabbing head is provided with a hanging face which is arranged upwards and used for being matched with the upper cavity wall of the grabbing cavity in a stopping mode so that the duct piece can be hung on the grabbing head. According to the duct piece lifting appliance, automatic operation can be achieved, a duct piece bolt does not need to be screwed into a duct piece bolt hole manually, and the duct piece bolt does not need to be hung on the lifting appliance manually, so that the efficiency is higher, and the safety of workers can be effectively guaranteed.
本发明涉及隧道掘进用的管片吊具技术领域,具体涉及一种管片吊具,管片吊具,包括吊梁,吊梁的两端设置有用于与吊机的吊钩进行连接的吊点,吊梁的中部转动装配有转轴,吊梁上设置有用于安装转轴的安装孔,吊梁上安装有与转轴传动连接以驱动转轴旋转的驱动机构,转轴包括轴线沿上下方向延伸的转动杆,转动杆的下端设置有用于穿过管片上的插入口伸入管片的抓取腔中并进行转动的抓取头,抓取头具有朝上设置的用于与抓取腔的上腔壁挡止配合以使管片挂接在抓取头上的挂接面。本发明的管片吊具可以实现自动化操作,不需要人工先将管片螺栓旋入管片螺栓孔中,也不需要人工再将管片螺栓挂在吊具上,因此效率更高,并且能够有效保障工人安全。
