Problems solved by technology

When the equipment enters and leaves the cabin, if it is hoisted in and out according to the vertical direction of the conventional large opening of the structure, it will cause great damage to the hull structure, the workload of assembly and welding is huge, and sometimes it will affect the layout of deck machinery. It is often difficult to carry out the method of lifting in and out in the vertical direction of the opening

Embodiment 1

[0033] Such as Figure 1-Figure 6 As shown, this embodiment provides a method for entering the cabin of minimally invasive equipment in the general section of the ship, including the following steps:

[0034] Step 1. Open several hoisting round holes 9 at designated positions on the deck surface. The center line of several hoisting round holes 9 coincides with the centerline of the travel track of the equipment 7 to be hoisted, defining the hoisting from one side of the cabin to the other side. The round holes 9 are the first hoisting round hole to the Nth hoisting round hole, and the Nth hoisting round hole is located directly above the installation position of the equipment 7 to be hoisted. The diameter of the hoisting circular holes 9 is 300mm, and the distance between the centers of two adjacent hoisting circular holes 9 is 2-2.5m.

[0035] Step 2: Install semi-circular steel 2 on the edge of hoisting round hole 9, the arc surface of semi-circular steel 2 faces the center...

Embodiment 2

[0042] This embodiment provides a method for leaving the cabin of minimally invasive equipment in the general section of the ship. This method is the opposite of the hoisting process in Embodiment 1. The steps are as follows:

[0043]Step 1. Open several hoisting round holes 9 at designated positions on the deck surface. The center line of several hoisting round holes 9 coincides with the centerline of the travel track of the equipment 7 to be hoisted, defining the hoisting from one side of the cabin to the other side. The round holes 9 are the first hoisting round hole to the Nth hoisting round hole, and the Nth hoisting round hole is located directly above the installation position of the equipment 7 to be hoisted.

[0044] Step 2: Install a semi-circular steel 2 on the edge of the hoisting round hole 9, the arc surface of the semi-circular steel 2 faces the center of the hoisting round hole 9, and the semi-circular steel 2 and the edge of the hoisting round hole 9 are fixed ...

Abstract

The invention discloses a cabin entry method and cabin exit method for minimally invasive equipment for a ship block. The cabin exit method comprises the following steps: 1, hoisting round holes, namely a first hoisting round hole to an Nth hoisting round hole are formed in a specified position on a deck surface; 2, half-round steel is additionally arranged on the edge of each hoisting round hole;3, a lifting hook of a first crane is connected with a first sling, and the first sling hoists to-be-hosted equipment to one side of a cabin; 4, the lifting hook of a second crane is connected with asecond sling, and the second sling enters the cabin from the first hoisting round hole and is connected with the to-be-hosted equipment; 5, the first crane and the second crane work alternately to move the to-be-hoisted equipment; and 6, the fifth step is repeated till the to-be-hoisted equipment moves to the position over the Nth hoisting round hole, and the to-be-hoisted equipment is hoisted inplace. According to the cabin entry method and cabin exit method for the equipment, the equipment enters and exits the cabin from the side surface of the cabin, and the equipment is hoisted in placein a relay advancing mode, so that the cabin entry and cabin exit workload of the equipment is obviously reduced.

Description

technical field [0001] The invention belongs to the technical field of shipbuilding, and in particular relates to a method for entering and leaving a cabin of minimally invasive equipment in a general section of a ship. Background technique [0002] At present, China has become a major shipbuilding country in the world. All kinds of ships will choose the advanced production method of general block construction in order to increase the construction speed. However, due to various reasons during the construction process, such as the pre-installed equipment needs to be out of the cabin for repair, and the equipment needs to enter the cabin due to late arrival. When the equipment enters and leaves the cabin, if it is hoisted in and out according to the vertical direction of the conventional large opening of the structure, it will cause great damage to the hull structure, the workload of assembly and welding is huge, and sometimes it will affect the layout of deck machinery. It i...
