The invention discloses a device for preventing a diversion sheave from disengaging from a groove. The device comprises a safety grating generating device, a safety grating receiving device and a fixed mounting seat, the fixed mounting seat is fixed on the diversion sheave housing; the safety grating generating device and the safety grating receiving device are respectively mounted at preset positions on two sides of the lower part of the diversion sheave through the fixed mounting seat; the safety grating receiving device is in communication connection with the elevator control cabinet and sends a monitoring signal to the elevator control cabinet in real time; due to the preset position, when a traction steel wire rope does not exist in a wheel groove of the diversion sheave, infrared light emitted by the safety grating generating device can be received by the safety grating receiving device; when the traction steel wire rope normally works in the wheel groove of the diversion sheave, infrared light emitted by the safety grating generating device is blocked by the traction steel wire rope, and the safety grating receiving device cannot receive the infrared light. The device for preventing the diversion sheave from disengaging from the groove is low in cost, convenient to install and low in misjudgment rate.

    本发明公开了一种反绳轮防脱槽装置,包括:安全光栅发生装置、安全光栅接收装置和固定安装座;所述固定安装座固定在反绳轮罩壳上,安全光栅发生装置与安全光栅接收装置通过固定安装座分别安装于反绳轮下部两侧的预设位置;安全光栅接收装置与电梯控制柜通讯连接,实时向电梯控制柜发送监测信号;所述预设位置使得,当反绳轮的轮槽中没有曳引钢丝绳时,安全光栅发生装置发射的红外光能够被安全光栅接收装置接收到;当曳引钢丝绳在反绳轮的轮槽中正常工作时,安全光栅发生装置发射的红外光被曳引钢丝绳阻挡,安全光栅接收装置无法接收到所述红外光。本发明的反绳轮防脱槽装置低成本、安装便利、误判率低。
