Light-boat-hanging, raft-hanging and goods-hanging three-purpose reel cart for ship

Abstract

The invention discloses a three-use winch for hoisting a boat, a raft and goods on a ship, which includes a hydraulic motor, an over-speed governor, an idle gear box, a reducer, a main drum, a slidingbearing, a sliding bearing support, a base, a small drum and a clutch of the small drum, wherein, the main drum and the small drum are bore on the same axis and are connected with each other throughthe clutch of the small drum. An output shaft of the hydraulic motor is connected with an input terminal of the reducer which is connected with the main drum; the hydraulic motor is connected with aninput shaft of the over-speed governor via a pair of idle gears. When the boat and the raft are landed by gravity, rotation speed of the main drum is decreased under the function of the friction resistance moment of the reducer and the boat and the raft are safely landed. When the goods are hoisted, the main drum and the small drum are disconnected by the clutch of the small drum; the main drum rotates to hoist the goods without rotation of the small drum. The three-use winch for hoisting the boat, the raft and the goods on the ship combines an existing boat and raft winch and a goods winch into one winch, simplifies the structure of a ship hoisting machine and reduces the manufacture cost of the ship hoisting machine, thereby having favorable promotion prospect.

Description

technical field [0001] The invention relates to a marine crane, in particular to a crane capable of taking off and landing lifeboats and rafts and lifting cargo, and belongs to the technical field of marine outfitting equipment. Background technique [0002] At present, the lifeboats, raft cranes and cranes equipped with various domestic ships are equipped with two winches, one is a winch for lifting and landing lifeboats and rafts, and the other is a cargo winch for lifting cargo. The reason why it cannot be combined with the cargo winch is that the winch can only realize electric lifting, or remote control manual lifting, and the lowering of the raft is realized by the gravity of the raft itself, so the raft winch cannot lift cargo. The hoisting winch drives the reel to rotate through the electric motor or hydraulic motor to drive the reducer, so as to control the lifting and lowering of the cargo. Since the motor, the reducer and the reel work synchronously, it cannot be ...

AI Technical Summary

Problems solved by technology

[0004] The technical problem to be solved by the present invention is: in view of the existence of existing marine lifesaving, rescue and lifting cranes, two hoisting winches must be installed at the same time to realize the lifting and landing of lifeboats, rafts and lifting goods respectively. The marine crane has the disadvantages of huge structure, cumbersome operation and high equipment cost. A three-purpose winch for marine davit, raft and cargo hoist is proposed, which combines the boat winch and the cargo winch into one. The three-purpose winch is adopted , can simplify the structure of the marine crane and reduce the manufacturing cost of the marine crane
