This utility model relates to the field of cable winding and unwinding, and in particular to an infrared proximity alarm device for cable reels. It includes a support base, inside which a drive motor is installed. An emergency stop assembly is located at the end of the drive motor furthest from the support base. The emergency stop assembly includes a compression spring, with two compression blocks fixedly connected to both ends of the compression spring. An outer locking tooth and an inner locking tooth are fixedly connected to the side of each compression block furthest from the movable fixed post, respectively. An inner gear disk is engaged with the side of the outer locking tooth furthest from the compression block, and an outer gear disk is engaged with the side of the inner locking tooth furthest from the compression block. This utility model, through the bidirectional engagement and locking design of the inner and outer gear disks and locking teeth, combined with the elastic force of the compression spring, can quickly lock the inertial rotating support sleeve after the drive motor is powered off. This mechanical linkage structure achieves millisecond-level bidirectional self-locking, greatly shortening the emergency stop response time and improving personnel safety protection in high-risk winding scenarios.
