The invention relates to an anchor chain constraint device. The anchor chain constraint device comprises a rolling wheel and a support used for fixing the rolling wheel to a main deck, wherein a groove is formed in the circumferential edge of the rolling wheel, an anchor chain penetrates through the groove, and a shaft hole is formed in the center of the rolling wheel. The anchor chain constraint device further comprises a constraint structure. The constraint structure comprises a camber beam, a shaft lever and nuts, wherein the camber beam is arranged across the rolling wheel, round holes through which the shaft lever can penetrate are formed in the two ends of the camber beam, external threads in screwing fit with the internal threads of the nuts are formed in the outer surface of the shaft lever, and the shaft lever penetrates through the shaft hole of the rolling wheel. The anchor chain constraint device is provided with the constraint structure, and the constraint structure can limit the sliding space of the anchor chain in the groove of the rolling wheel so that the anchor chain is prevented from escaping from the rolling wheel when an anchor is weighed or dropped.
