Embodiment Construction

[0050] In the following, the present invention will be more clearly and completely described by way of embodiments in conjunction with the accompanying drawings, but the present invention is not limited to the scope of the described embodiments.

[0051] Such as Figure 1-Figure 7 As shown, this embodiment discloses a hoisting method for the general section of the bow of a bulk carrier. The general section of the bulk carrier includes a general forecastle deck section 1, a middle section 2 of the forecastle deck deck, and a bulwark section 3. Lifting methods include:

[0052] Step 100 , splitting the middle segment 2 of the forecastle deck into a segment 21 with an outer plate and a segment 22 without an outer plate.

[0053] Such as Figure 4-Figure 6 As shown, in this embodiment, when splitting the middle section of the forecastle deck, the sum of the weights of the forecastle deck section 1, the section with outer plate 21 and the bulwark section 3 is less than the maximu...

Abstract

The invention discloses a hoisting method of a bulk cargo ship bow block. The bulk cargo ship bow block comprises a forecastle deck block, a forecastle deck middle section and a bulwark section. The hoisting method comprises the steps of S1, splitting the forecastle deck middle section into a section with an outer plate and a section without an outer plate; S2, assembling the section with the outer plate, the bulwark section and the forecastle deck block to form a forecastle deck block with a bulwark; S3, hoisting the forecastle deck block with the bulwark to a dock; and S4, hoisting the section without the outer plate to the forecastle deck block with the bulwark and installing. According to the hoisting method, the forecastle deck middle section is split and then recombined with the forecastle deck block and the bulwark section, so that the maximum hoisting capacity of a workplace is utilized to the maximum extent, the total section number is increased, the hoisting number in the dock is reduced, and economic benefits are improved.

Description

technical field [0001] The invention relates to a hoisting method for the general bow section of a bulk carrier. Background technique [0002] At present, in order to increase the speed of shipbuilding, multiple sections are built at the same time, and then the multiple sections are assembled into a general section, and finally the general section is hoisted to the dock by a gantry crane for final assembly. When hoisting in the general section, it is necessary to consider the hoisting capacity of the workplace, expand the total number of sections, and reduce the number of hoisting in the dock to increase the speed of shipbuilding. Among them, there are less equipment and outfitting parts in the bow area, and a multi-layer segmented general group is adopted to maximize the use of the lifting capacity of the workplace and reduce the number of hoisting. [0003] For example, in order to meet the maximum lifting capacity requirements of two gantry cranes combined hoisting, the ...
