Device and method for detecting groove disengaging of steel wire rope of crane pulley block

The invention relates to a crane pulley block steel wire rope groove disengaging detection device which comprises a fixing support and a plurality of detection sensors, the fixing support is arranged above a pulley block base, the detection sensors are arranged on the fixing support, and the number of the detection sensors is the same as that of pulleys. And the plurality of detection sensors respectively and independently face the corresponding pulleys. The invention also relates to a method for detecting groove separation of the steel wire rope of the crane pulley block. Whether the steel wire rope is separated from the groove or not is detected in real time, and the steel wire rope and a transmission part are effectively protected against abrasion caused by vertical movement of the steel wire rope. 本发明涉及一种行车滑轮组钢丝绳脱槽检测装置，包括固定支架和多个检测传感器，所述固定支架设置于滑轮组底座的上方，多个所述检测传感器设置于固定支架处，所述检测传感器的数量与滑轮数量相同，且多个检测传感器分别单独朝向对应的滑轮。本发明也涉及行车滑轮组钢丝绳脱槽的检测方法。本发明实时检测钢丝绳是否脱槽，有效的保护了钢丝绳和传动部件因钢丝绳上下动作导致的磨损。
