The invention discloses a mechanical interlocking safety device for an elevator. The device comprises a main hanging wheel which is arranged in the center of the upper part of a lifting cage, whereina hoisting steel wire rope connected with a traction machine is arranged above the lifting cage and connected with the main hanging wheel, an auxiliary hanging wheel is arranged above the main hangingwheel, is abutted and connected with the hoisting steel wire rope on one side from inside to outside and is rotationally connected with the upper end of an overturning rod, the overturning rod extends to the lower right part, the lower part of the overturning rod is rotationally connected to angle iron at the top of the lifting cage, a spring I is connected with the upper part of the overturningrod, and the other end of the spring I extends to the lower right part and is fixed on the edge of the upper end of the lifting cage. Defects in the prior art are overcome, the structure is reasonable, the mechanical interlocking safety device is added to the lifting cage on the basis that an anti-falling safety device is mounted on the lifting cage, the lifting cage is suspended and clamped on ahorizontal web member of a guiding track bracket by a steel plate hook head and a steel plate arresting device, and the multiple protecting effects are realized.
本发明公开了一种升降机用机械连锁安全装置,包括主吊轮,所述主吊轮设置于吊笼的上部中心处,所述吊笼上方设有连接曳引机的起重钢丝绳,所述起重钢丝绳连接主吊轮,所述主吊轮上方设有副吊轮,且副吊轮从内向外紧靠连接一侧的起重钢丝绳,所述副吊轮转动连接在翻转杆上端,所述翻转杆向右下方延伸且下部转动连接在吊笼顶部的角铁,所述翻转杆上部连接弹簧一,所述弹簧一另一端向右下方延伸且固定在吊笼上端边缘处。本发明克服现有技术缺点,结构合理,在吊笼上在安装防坠安全器基础上增加了机械连锁安全装置,利用钢板钩头和钢板止档将吊笼悬挂和卡在导轨架的水平腹杆上,起到多重保护的效果。
