The segment assembly anti-falling device limits the position of the segment by matching the pull plate, spring A, protrusion, hinged plate, spring B, and limiting head, so that the segment is adsorbed by the sucking disc. The positioning rod is flipped by the cooperation of the positioning block, through hole A, and insertion hole, to fix the position of the pull plate. This technical solution requires two steps to achieve the purpose of constraint and fixation, including adjustment of the pull plate on both sides and positioning of the positioning rod. The structure is relatively complex, the steps are cumbersome, and the speed is slow. Chinese patent CN217421220U discloses a segment assembly machine for small-diameter shield machines. The segment assembly anti-falling device assists in fixing the segment by setting a gripper device beside the vacuum adsorption device, to prevent the segment from falling and causing casualties to a certain extent. The gripper fixation of this technology is achieved by friction force, and the function of segment anti-falling is limited. In summary, the existing anti-falling device usually uses the screwing bolt method to limit the segment, but the operation method is cumbersome and the construction efficiency is low.
