The invention discloses a top rushing falling preventing device, and relates to the technical field of lifter safety protection. According to the technical scheme, the top rushing falling preventing device comprises a steel tower frame, one side of the steel tower frame is provided with a material lifter, and the top of the steel tower frame is provided with a buffering device for buffering the material lifter; the buffering device comprises a supporting plate for abutting against the top of the material lifter; a plurality of supporting springs are connected between the upper surface of the supporting plate and the steel tower frame, and the two ends of the supporting springs are fixedly connected to the supporting plate and the steel tower frame; the top of the steel tower frame is fixedly connected with vertical limiting rods, and the limiting rods are located outside the range over the material lifter; the supporting springs are installed on the limiting rods in a sleeving mode, and the lower ends of the limiting rods penetrate through the supporting plate and are fixedly connected with limiting blocks; and the steel tower frame is further provided with a linkage mechanism which is used for supporting the material lifter when the supporting plate is lifted up. The top rushing falling preventing device is reasonable in structure, and the situation that the material lifter accidently rushes towards the top and falls in the ascending process can be effectively prevented.

    本发明公开了一种防冲顶坠落装置,涉及升降机安全防护技术领域。技术方案为一种防冲顶坠落装置,包括钢塔架,钢塔架一侧安装有物料提升机,钢塔架的顶部设置有用于缓冲物料提升机的缓冲装置,缓冲装置包括用于抵接物料提升机顶部的支撑板,支撑板的上表面与钢塔架之间连接有多个支撑弹簧,支撑弹簧的两端分别固定连接于支撑板和钢塔架,钢塔架的顶部还固定连接有竖直的限位杆,限位杆位于物料提升机正上方范围之外,且支撑弹簧套接在限位杆上,限位杆的下端穿过支撑板并固定连接有限位块,且钢塔架上还设置有于支撑板被顶起时以支撑物料提升机的联动机构。本发明结构合理,能够有效防止物料提升机在上升时意外冲顶而导致坠落。
