Abstract

The invention discloses a hawser winch drum, and belongs to the field of marine hawser winches. The hawser winch drum comprises a first drum body, a second drum body and drum side plates, wherein thefirst drum body and the second drum body are oppositely arranged. The drum side plates comprise the first drum side plate and the second drum side plate, the first drum body and the second drum body have the same structures, the first drum body is of a semi-arc structure, one end of the first drum body and one end of the second drum body are both connected with the first drum side plate, and the other end of the first drum body and the other end of the second drum body are both connected with the second drum side plate. An opening for containing an emergency release device is formed between the first drum body and the second drum body, a first pin shaft mounting hole is formed in the first drum body, a second pin shaft mounting hole is formed in the second drum body, and the first pin shaft mounting hole and the second pin shaft mounting hole are coaxially formed. According to the hawser winch drum, the emergency release device can be integrated in the drum of a hawser winch, so that the mounting space of a deck is saved.

Description

technical field [0001] The invention relates to the field of large cable winches for ships, in particular to a large cable winch drum. Background technique [0002] During the oil transportation process of the crude oil export system, the shuttle tanker is connected with the large cable winch on the FPSO (Floating Production Storage and Offloading) through cables. When the sea condition suddenly deteriorates, the pulling force of the cable will increase sharply, and the excessive pulling force will cause permanent damage to the winch. Therefore, an emergency release device is usually provided on board to protect the safety of the large cable winch. [0003] Both the large cable winch and the emergency release device are arranged on the deck of the ship. In an emergency, the emergency release device can directly transmit the tension transmitted by the cable to the hull, so that the main structure such as the drum support of the large cable winch does not need to bear the moo...
