Description

Technical Field

[0001] The present invention relates to the technical field of ship equipment, and in particular to a ship hoisting device and a control method thereof. Background Art

[0002] On various ships equipped with naval guns, for the sake of safety isolation and rapid fire extinguishing, the ammunition compartment is generally set below the waterline of the ship and on the lower deck far away from the gun body. In order to ensure the timely and normal supply of ammunition, it is often necessary to install a hoisting device on the ship to transport ammunition. In order to avoid the ammunition on the conveyor belt from exploding to the ammunition compartment when the gun body is damaged and explodes, causing the ammunition compartment to explode, the ammunition is generally not transported by a conveyor belt type transport mechanism. Unless there is a special need, the automatic delivery / loading method is generally not used, and the ammunition is transported by a hoisting device that completely separates the gun body and the ammunition compartment.

[0003] At present, the electrical control circuit of the ammunition hoisting device mainly adopts the relay control mode, which has complex circuits, single functions and cumbersome operation. Especially in some ships with large ammunition transport capacity, dual channels are set up. The use of relay control requires three people to participate in the operation of the equipment. The operators at the loading position, unloading position and control position communicate with each other. After confirming that the ammunition boxes at the loading position are placed and the empty boxes at the unloading position are in place, the control position operates the ammunition hoisting device to transport ammunition, which has low work efficiency and heavy personnel load.
