Abstract

The invention discloses a tug tail cable lifting device. The invention welds the left support base and the right support base at the ship side positions on both sides of the special cable guide hole,and the left support base and the right support base are respectively provided with bolt holes; The bottom ends of the left bracket and the right bracket are respectively passed through the through bolts 5, through bolt 6 is hinged to the left and right bracket bases, When erection is required, the top ends of the left bracket and the right bracket are connected to form a triangular bracket through a through bolt 1, and the through bolt 2; the pulley is fixed at the top end connection of the left bracket and the right bracket; one end of the steel wire rope is connected with a shackle by bypassing the pulley through a bolt; and the other end of the steel wire rope is connected with the original electric winch on the rear deck of the tug. The invention solves the problem that the tugboat isdifficult to turn in the coastal towing operation process, improves the working efficiency of the ship towing operation, and has the advantages of simple structure, safety and effectiveness.

Description

technical field [0001] The invention relates to a tugboat stern tow cable hoisting device, which belongs to the technical field of ship equipment. Background technique [0002] In addition to top towing large ships entering and leaving the port, port tugboats also have coastal towing operations. The main tows are crane ships, barges and other non-self-propelled or unseaworthy ships. These types of ships generally have a large tonnage. During the towing operation, the tugboat and the object to be towed are connected by a steel wire tail tow cable with a diameter of 5.6 cm and a length of about 700 meters. In order to prevent the stern tow cable from swinging left and right when encountering severe weather such as strong winds and waves or swells during the towing operation, it is necessary to pass the stern tow cable into the special fairlead at the tail of the tugboat, which can also prevent left and right swaying Fray the rope. However, when the tugboat tows the towed obj...
