Problems solved by technology

[0003] However, when the main engine enters the cabin before hoisting the superstructure, because the main engine enters the cabin earlier, it requires an earlier arrival time of the main engine, the order cycle is relatively tight, and the pressure on capital operation is high; in addition, after entering the cabin, due to There are a lot of other component assembly work that needs to be carried out, which can easily cause damage to the main unit

Embodiment

[0038] The traditional method of hoisting the main engine equipment of car-passenger ferries is difficult to operate because of the high hoisting height, and it is easy to cause damage to the main engine due to misoperation. The method for hoisting the main equipment of the car-passenger ferry of the present invention can be applied to the hoisting of the main equipment of small and medium-sized car-passenger ferries such as 50m, 60m, 74m, and 85m, and the weight of the main equipment is generally about 10 tons. The specific hoisting method includes the following steps:

[0039] Step 1, design the host hoisting mast tooling

[0040] like Figure 1-3 As shown, the portal frame tooling 1 adopted in the present invention includes a first horizontal base 101 and a second horizontal base 102 arranged front and back, and the two horizontal bases are preferably channel steel bases; the first horizontal base 101 is provided with The first vertical steel pipe 103, the second vertical...

Abstract

The invention relates to the technical field of ship construction and particularly discloses a hoisting method for main engine equipment of a vehicle passenger ferry. The hoisting method sequentially comprises the steps that a portal frame tool is designed; the main engine equipment is hoisted on the tool; a translation track is laid on an entrance hatch of the main engine equipment; the main engine equipment and the tool are overall moved to a predetermined position through a tank trolley; the translation track and the tank trolley are dismantled in a jacking mode; and the main engine equipment is made to fall inside a cabin. According to the hoisting method, the time of entering the cabin of the main engine equipment can be freely controlled, and operation is easy convenient and efficient.

Description

technical field [0001] The invention relates to the technical field of ship building, in particular to a method for hoisting main equipment of a car-passenger ferry. Background technique [0002] Small and medium-sized car-passenger ferries, the ferry series include 50m, 60m, 74m, 85m and other specifications, the weight of each main engine equipment is generally about 10 tons, generally has four engines and four propellers (that is, four main engines, four propellers), and left and right Symmetrically arranged, this kind of ferry is usually arranged with a superstructure above the main cabin area. The shipbuilding process under the existing technical conditions requires that the main engine needs to be hoisted to advance the superstructure. [0003] However, when the main engine enters the cabin before hoisting the superstructure, because the main engine enters the cabin earlier, it requires an earlier arrival time of the main engine, the order cycle is relatively tight, an...
