The invention belongs to the technical field of hoisting machinery, and particularly relates to a hoisting machinery lifting hook group and a safe replacement method thereof. Comprising a bearing shaft, the bearing shaft is sleeved with a plurality of pulleys and an upper yoke plate, a steel wire rope is hung on the pulleys, a protective cover is bolted to the upper yoke plate, lower yoke plates are inserted into the bottom of the upper yoke plate, a lifting hook is installed between the lower yoke plates, and one side of the upper yoke plate and one side of the lower yoke plate are connected with a first vertical plate through fixing bolts. The other side of the upper yoke plate and the other side of the lower yoke plate are connected with a second vertical plate through fixing bolts. Gaps are formed in the middle of the bottom of the upper yoke plate and the two ends of the upper side of the lower yoke plate. The steel wire rope is moved out to the lifting hook set through the gap by staggering the upper yoke plate and the lower yoke plate, the operation of replacing the lifting hook set can be completed by a single person, the whole steel wire rope does not need to be pulled out through manual traction and then installed, the working intensity is greatly relieved, the replacement time is shortened, and the working efficiency is improved.

    本发明属于起重机械技术领域,尤其涉及一种起重机械吊钩组及其安全更换方法。包括承重轴,所述承重轴上套接有若干滑轮、上轭板,滑轮上挂接有钢丝绳,上轭板上栓接有护罩,上轭板底部插接有下轭板,下轭板之间安装有吊钩,上轭板、下轭板的一侧通过固定螺栓连接有第一立板,上轭板、下轭板的另一侧通过固定螺栓连接有第二立板,上轭板底部中间位置及下轭板上侧两端设有空隙。本发明通过上轭板和下轭板的错位来将钢丝绳通过空隙移出到吊钩组,单人即可完成更换吊钩组的操作,无需通过人工牵引将整个钢丝绳抽出后再安装,大大减轻了工作强度,缩短了更换时间,提高了作业效率。
