Problems solved by technology

For common cargo ships, the size of each hatch circumference is relatively large. Generally, it is divided into 8 pieces for hoisting. The construction intensity is high, which affects the berth cycle, high construction cost and low efficiency.

Embodiment Construction

[0027] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0028] This embodiment takes a 15,000-ton bulk carrier as an example, which has three cargo holds in total, and the opening size of each cargo hold is 19,000X33,400. Each side of the hatch enclosure is divided into two pieces, each cabin has 8 pieces in total, and the weight is about 55 tons (except for pipe and outfitting electrical parts); after the hatch enclosure is hoisted as a whole, each hatch enclosure only needs to be hoisted once, which can reduce 23 hoisting times. Reduced berth cycle.

[0029] The hatch enclosure closing and hoisting method of the present invention comprises the following steps:

[0030] Measurement steps, measuring various data of the hatch coaming and the deck on which it is located, these data include: the actual length, width, height, diagonal line of the hatch coaming and the distance between the ribs of the closing mouth, t...

Abstract

The invention discloses a hatch coaming closing and hoisting method. The hatch coaming closing and hoisting method comprises the following steps: measurement: measuring various data of a hatch coaming and a deck and preparing a hatching datasheet; hatch coaming final assembly: manufacturing a hatch coaming final assembly jig frame, hoisting longitudinal sections and transverse sections of the hatch coaming onto the hatch coaming final assembly jig frame, conducting measurement and adjustment and conducting spot welding for fixation after preset final assembly accuracy is satisfied; accessory installation: installing pipe fittings, cables and outfitting on the assembled hatch coaming structure; integral hoisting: hoisting the assembled hatch coaming structure and accessories thereof as an integral body according to preset hoisting accuracy. The hatch coaming closing and hoisting method has the advantages that one step of hoisting is only needed after integral closure and the time on a building berth and the construction strength are effectively reduced.

Description

technical field [0001] The invention relates to ship building technology, in particular to a method for closing and hoisting a hatchway. Background technique [0002] At present, in the traditional ship construction process, the construction of the hatch coaming mainly adopts the method of segmental hoisting, that is, firstly build in segments, and then hoist to the general assembly on the ship. For common cargo ships, the size of each hatch circumference is relatively large, and it is generally selected to be divided into 8 pieces for hoisting. The construction intensity is high, which affects the cycle of the berth, and the construction cost is high and the efficiency is low. Contents of the invention [0003] The purpose of the present invention is to provide a hatch enclosure closing and hoisting method, after the overall closing only needs to be hoisted sequentially, which effectively reduces the berth period and construction intensity, so as to solve one or more prob...
