The invention discloses a lifting chain blocking prevention device for a lifting chain. The lifting chain blocking prevention device includes a chain block, the chain block is provided with a blockingprevention part, and the blocking prevention part is connected with the chain block through bolts; the blocking prevention part includes a horizontal V-shaped supporting frame, and horizontal flat steel is connected below the V-shaped supporting frame; and the two ends of the flat steel are bent downwards, and a chain inlet pipe and a chain outlet pipe are arranged on the inner side of the bending position. According to the lifting chain blocking prevention device, the blocking prevention part is arranged on the chain block, the blocking prevention part is composed of the V-shaped supportingframe and the flat steel, the two ends of the flat steel are bent downwards, the chain inlet pipe and the chain outlet pipe are respectively arranged on the inner side of the bending position, that is, the chain inlet pipe and the chain outlet pipe are respectively located at the two ends of the flat steel, a chain enters from the chain inlet pipe and exits from the chain outlet pipe, and the direction of the chain inlet pipe and the chain outlet pipe is along the tangential direction of the two sides where the chain enters and goes out of the chain block, so that the blocking of the lifting chain in the use process is avoided, the work efficiency is improved, and the service life of the chain is prolonged.

    本申请公开了一种用于吊链的防吊链卡堵装置,包括手拉葫芦,所述手拉葫芦上设置有防卡堵部件,所述防卡堵部件通过螺栓与手拉葫芦连接,所述防卡堵部件包括水平设置的V型支撑架,所述V型支撑架下方连接有水平设置的扁钢,所述扁钢两端向下弯折并且在弯折处的内侧设置有进链管、出链管。本申请通过在手拉葫芦上设置防卡堵部件,防卡堵部件由V型支撑架、扁钢组成,扁钢的两端向下弯折,在弯折处的内侧分别设置进链管、出链管,即进链管、出链管分别位于扁钢的两端,链条自进链管进入、出链管出去,进链管、出链管的方向沿着链条进出手拉葫芦两侧的切线方向,避免了吊链在使用过程中出现卡堵,加快了工作效率,延长了链条的使用寿命。
