The invention discloses a lifting steel wire rope breakage preventing device for a tower crane. The crane, end plates and stand columns are included, the upper end of the upper end plate is fixedly connected with the crane, a winding and unwinding assembly is arranged on the outer wall of one end plate, and the winding and unwinding assembly comprises a first support seat, an auxiliary steel wirerope, grooved pulleys, material rollers, a servo motor, bearings, a first vertical plate and a main steel wire rope. The outer side of the grooved pulley on the outer side is connected with the main steel wire rope in an attached mode, and the upper end of the main steel wire rope is connected with an internal winding-unwinding roller of the crane in a winding mode. The lifting steel wire rope breakage preventing device for the tower crane is scientific and reasonable in structure and safe and convenient to use, and is provided with the main steel wire rope, a pulley, the material rollers, a disc, a pawl, a ratchet wheel, a lifting ring, the servo motor and the auxiliary steel wire rope, the material rollers can pull the lifting ring and hoist an object through the auxiliary steel wire rope, and the problem that when the steel wire rope is broken, part of the steel wire rope needs to be clamped on one side to clamp the position of the hoisted object, gravity center shifting and shakingare likely to happen, and potential safety hazards exist is solved.

    本发明公开了一种用于塔吊的起升钢丝绳防断绳装置,包括吊车、端板和立柱,上方所述端板的上端与吊车固定相连,所述端板的外壁设置有收放组件,所述收放组件包括第一支撑座、辅钢丝绳、槽轮、料辊、伺服电机、轴承、第一竖板和主钢丝绳,外侧所述槽轮的外侧与主钢丝绳贴合相连,所述主钢丝绳的上端与吊车的内部收放辊轮缠绕相连。该用于塔吊的起升钢丝绳防断绳装置,结构科学合理,使用安全方便,设置有主钢丝绳、滑轮、料辊、圆盘、棘爪、棘轮、吊环、伺服电机和辅钢丝绳,料辊可通过辅钢丝绳拉住吊环和起吊物品,避免了在钢丝绳断裂时需通过一侧夹持住部分钢丝绳卡住起吊物品位置容易出现重心偏移且晃动导致存在安全隐患的问题。
