The invention relates to an underwater lifting point rooting device which comprises a main shaft, a handle is installed at the top of the main shaft, a clamping groove sleeve is installed in the middle of the main shaft in a matched mode, a connecting base is arranged at the bottom of the main shaft, a plurality of rooting claws are evenly hinged to the outer side of the connecting base, and the inner side of each rooting claw is connected with the clamping groove sleeve through a connecting rod. A plurality of extension springs are arranged between the clamping groove sleeve and the connecting seat, each extension spring is matched with the upper surface of the connecting seat through a first connecting pin, and each extension spring is matched with the clamping groove sleeve through a second connecting pin; a groove is formed in the shaft end of the main shaft, the interior of the groove and an elastic shifting piece are installed in a matched mode through a fastener, a through groove corresponding to the elastic shifting piece is formed in the top of the clamping groove sleeve, and the elastic shifting piece prevents the extension spring from pulling the clamping groove sleeve downwards through the through groove in the initial state. The tensioning and opening of the rooting claws are controlled through the extension springs, so that the underwater lifting point rooting device can root on the wreckage, and the underwater lifting point rooting device is high in reliability and suitable for the deep sea environment.

    本发明涉及一种水下吊点生根装置,包括主轴,主轴的顶部安装有手柄,主轴的中部配合安装有卡槽套筒,主轴的底部设置有连接座,连接座的外侧均匀铰接有数个生根爪,每个生根爪的内侧通过连杆与卡槽套筒连接,卡槽套筒与连接座之间设置有数个拉伸弹簧,每个拉伸弹簧通过第一连接销与连接座的上表面配合安装,每个拉伸弹簧通过第二连接销与卡槽套筒配合安装;主轴的轴端设置有凹槽,凹槽的内部通过紧固件与弹性拨片配合安装,卡槽套筒的顶部设置有与弹性拨片对应的通槽,初始状态时弹性拨片通过通槽阻止拉伸弹簧下拉卡槽套筒。通过拉伸弹簧控制生根爪的收紧与张开,从而实现水下吊点生根装置在残骸上生根,可靠性强,适用于深海环境。
