Mooring winch with emergency quick cable release device

Abstract

The invention discloses a mooring winch with an emergency quick cable release device. The mooring winch with the emergency quick cable release device comprises a mooring winch body, a connecting device, and a hook body locking and releasing device, wherein the hook body locking and releasing device is coupled with a cable hook, and the connecting device is provided with a connecting vertical shaftwhich is vertically distributed; the connecting vertical shaft is externally sleeved with a shaft sleeve, and a connecting plate is fixedly arranged on the shaft sleeve; the hook body locking and releasing device also comprises a shell, and the back end of the shell is connected with the connecting plate through a first hinge pin; the front end of the shell is connected with a cable hook througha second hinge pin, and a first transmission part and a second transmission part are arranged in the shell; the first transmission part is provided with a first cam block and a push rod, and the second transmission part is provided with a second cam block and a rod-shaped portion; the upper end of the rod-shaped portion is provided with a locking roller, and a third rotating shaft is coupled witha locking sleeve; a locking tongue is arranged on the locking sleeve. The mooring winch with the emergency quick cable release device disclosed by the invention can realize the requirement of quick mooring and quick release, and has the advantages of saving space, saving working time and improving work efficiency.

Description

technical field [0001] The invention relates to the technical field of ship equipment, in particular to a mooring winch with an emergency quick release cable device. Background technique [0002] Liquefied natural gas carriers (LNG carriers) are very cold. Since the filling arms of the LNG carrier are made of rigid materials, the relative displacement between the filling ship and the receiving ship should be as small as possible during the filling operation to ensure that the filling arm will not be subject to a large load. For this reason, during the bunkering operation, the bunkering ship and the bunkering ship are fixed to each other by mooring cables, and the number of mooring cables is relatively large. [0003] At present, during bunkering operations, the conventional mooring mode is to tie the mooring cables of the bunkering ship to the mooring bollards of the bunkering ship. During the mooring operation, the mooring cable connected to the mooring cable needs to be ...

AI Technical Summary

Problems solved by technology

[0005] 1. The boarding and fastening of the mooring cables of the receiving ship is done manually by the crew, and the preparation time before the bunkering operation is relatively long

[0006] 2. Rely on the crew to untie the cable manually, which takes a long time

[0007] 3. In an emergency, the cable cannot be removed quickly, and the risk of filling operations is high

[0008] 4. Each mooring cable needs to be equipped with a cable pile for fastening, which requires a large space for the mooring deck, which is not conducive to the overall layout of the ship
