The invention relates to a swing guide pulley with swing angle range limiting and braking functions. The swing guide pulley comprises a pulley body, an electromagnetic brake, a rotating frame and a limiting plate. The pulley body is mounted at the front end of the rotating frame through a pin shaft; the upper end of the rotating shaft is connected with an electromagnetic brake rotor of the electromagnetic brake; a friction plate of the electromagnetic brake sleeves the lower end of the electromagnetic brake rotor and is fixed on the mounting device; when the electromagnetic brake is electrified, the electromagnetic brake rotor rotates to contact with the friction plate to generate friction force, and the rotating shaft stops rotating through the friction force; the limiting plate is installed on the electromagnetic brake rotor, a limiting groove is formed in the limiting plate, and the limiting bolt penetrates through the limiting groove to be fixed to the installation device. When the pulley body swings, the limiting bolt is limited through the limiting groove, and the swinging range of the pulley body is limited. The cable guiding device can limit the swing allowable range during working, can brake safely during non-working, can meet the cable guiding requirement, and ensures the safety of operation and storage.

    本发明涉及一种具有摆角范围限定及制动功能的摆动导向滑轮,包括滑轮本体、电磁制动器、旋转架和限位板;滑轮本体通过销轴安装在旋转架前端;旋转架包括转轴,转轴上端与电磁制动器的电磁制动器转子相连接;电磁制动器的摩擦板套接在电磁制动器转子下端并固定在安装装置上;电磁制动器通电时,电磁制动器转子转动与摩擦板接触产生摩擦力,通过摩擦力转轴停止转动;限位板安装在电磁制动器转子上,限位板上设有限位槽,限位螺栓穿过限位槽固定在安装装置上;当滑轮本体摆动时,通过限位槽对限位螺栓的限位,限制滑轮本体的摆动范围。本发明在工作时可限定摆动允许范围,非工作时能安全制动,同时能够满足缆索导向需求,保证作业及存放的安全性。
