Description
Technical Field
The utility model relates to an anchor chain jack belongs to boats and ships equipment technical field.
Background
With the development of technology, ships built by human beings have larger and larger tonnage and increasingly thick anchor chains, which have higher requirements on equipment such as ship cable anchors and the like commonly used at present. The largest vessels in the world today, up to 477 meters in length and 124 meters in width, have a maximum draft of over 30 meters, and their tonnage amounts to a striking 100 ten thousand tons, which corresponds roughly to the sum of 10 ford class aircraft carriers. The anchor chain is a chain connected between the anchor and the ship body and used for transmitting and buffering external force borne by the ship. Ships need to be anchored in a broken down mode under the conditions of cargo loading and unloading, wind sheltering, berthing waiting, tide waiting and the like. After the ship is anchored, the anchor and the anchor chain are dragged to move under the action of external force, and finally the anchor fluke gradually catches the bottom. When the holding force of the anchor and the anchor chain is balanced with the external force acting on the ship body or the inertia force of the ship moving, the ship is moored at the position. After the anchor is firmly held, the anchor chain with proper length is released, and the action of water flow, wind power and waves on the ship can be resisted by the anchor and the holding force generated by the anchor chain. The anchor chain may also be used in a stranded cable vessel.
The traditional mechanical equipment for hoisting and anchoring comprises a chain maker and an anchoring cable machine. The chain stopper is installed between the anchor cable machine and the anchor for clamping the anchor chain. During navigation, the gravity and the inertia force of the anchor are borne; when anchoring, the anchor chain bears the tension of the anchor chain to protect the anchor cable machine. The anchor cable machine is power mechanical equipment for taking up and breaking down the anchor. When the anchor is lifted, the anchor chain is collected into the chain cabin through the anchor cable machine. Instead, the anchor is run into the seafloor.
When the chain maker is installed, the center of the roller of the chain maker and the center of the roller of the anchor cable machine need to be ensured to be on the same line so as to ensure that the anchor chain is on the center lines of the roller of the chain maker, the roller of the anchor cable machine and the anchor chain pipe. The mounting quality of the chain maker and the anchor cable machine directly affects the stability and accuracy of the whole anchor chain reeling and unreeling system. The traditional anchor throwing and lifting equipment is adopted, so that the error is large, the size is large, the operation is difficult, and the cable anchoring machine can generate serious noise, so that the safety and the reliability of the whole anchor chain retracting system are influenced.
