Lifting device of hoist drum wire rope separation of overhead crane

摘要

Wire rope for lifting weight (1),For the crane drum (2) with steel wire ropes,The rotation of the hoist drum (2) is limited in advance according to the rotation number of the Joyce drum,In order to provide the speed reducers (4) and,In order to maintain the steel wire rope more safely, the frame drum groove (9) formed in the Hubei frame drum (2) is prepared,On the crane of the patio crane that moves the weight from the ground,The steel wire rope (1) is prevented from detaching from the host dream home (9), and the rope is tied in the groove in sequence. At the same time, in order to absorb the friction of the steel wire rope, the outer ear steel wire rope of the rolling ring is provided to detach from the protective belt (5),In order to avoid the separation of the wire rope (1) from the drum groove (9), and finally to sense the separation of the wire rope, a left and right movable anti-skid device (6) is used,The signals sensed from the previous ring switch (6) are cables (7) and,In order to support the wire rope disengagement protection belt (5) and the ring switch (6), a crane drum wire rope disengagement protection device including a bracket (8) is included.
