The invention discloses a crane steel wire rope groove disengaging fault detection protection device and method, and relates to the technical field of cranes. The crane comprises a crane arm arranged on a crane main body, a steel wire rope is arranged between the crane main body and the crane arm, the detection unit comprises a protection assembly and a trigger assembly, and a contact extrusion wheel used for carrying out groove disengaging protection on the steel wire rope is arranged in the protection assembly; a driving shaft matched with the steel wire rope is arranged in the triggering assembly; the locking unit comprises a synchronizing assembly and a clamping and locking assembly. The device has the advantages that by adopting the mode of limiting the two ends of the hoisting fixed pulley and limiting the middle of the steel wire rope, the steel wire rope can be effectively prevented from disengaging from a groove, normal take-up and pay-off of the steel wire rope cannot be affected, and the running state of the steel wire rope can be monitored in real time; and when abnormal conditions such as wire breakage are detected, the steel wire rope can be quickly locked and stopped, so that the operation safety of the crane is effectively improved.

    本发明公开了一种起重机钢丝绳脱槽故障检测防护装置及方法,涉及起重机的技术领域。本发明包括设置在起重机主体上的起重机臂,且起重机主体与起重机臂之间设置有钢丝绳,还包括:检测单元,包括防护组件与触发组件,其中防护组件内设置有用于对钢丝绳进行脱槽防护的接触挤压轮,触发组件内设置有与钢丝绳相配合的主动轴;锁定单元,包括同步组件与卡锁组件。优点在于:本发明通过采用对起重定滑轮进行两端限位与钢丝绳进行中部限位的方式,可有效避免钢丝绳脱槽,也不会影响到钢丝绳的正常收放线,并可对钢丝绳的运行状态进行实时监控,当检测到断线等异常情况时可实现钢丝绳的快速卡锁截停,有效提高起重机的运行安全性。
