Embodiment Construction

[0025] Below in conjunction with accompanying drawing, the installation method of a kind of ship chimney general section water cannon platform of the present invention is described further, in order to understand the application process of the present invention method more clearly, but can not limit protection scope of the present invention with this.

[0026] like figure 1 As shown, the height of the chimney general section is 30 meters, and the height of the chimney general section 1 is 80 meters from the bottom of the dock after hoisting to the ultra-large container ship, and the four water cannon platforms 2 are respectively fixed on the chimney general At the protruding position of the end walls on both sides of the top deck of the chimney at the top of the section 1, the four water cannon platforms 2 protrude to the outside of both sides after being fixed and installed on the general section 1 of the chimney. Since the highest point of the chimney section 1 is as high as...

Abstract

The invention relates to a method for installing a water cannon platform on a chimney block in an ultra-large container ship, which mainly comprises the following steps that: (1) a structural designer correspondingly optimizes a slab joint corresponding to the water cannon platform to ensure that the structure of the water cannon platform protruding out of a chimney top deck and the slab joint are correspondingly optimized; (2) making a corresponding water cannon platform structure into a complete bulk piece; (3) the water cannon platform is assembled in place in the block stage, and the water cannon platform falls down towards the deck surface of the chimney top and is fixed through angle steel; (4) mounting the hinge on a chimney top deck and a water cannon platform; and (5) after the chimney block is carried in place, dismounting the fixed angle steel by a constructor, putting the water cannon platform to a corresponding position by using a hoist, and welding. According to the method, the double completeness of the chimney block structure and fitting-out is guaranteed, the scattered hoisting work of the uppermost layer of chimney segments is avoided, most of the high-altitude operation amount is avoided, and meanwhile the dock period is shortened.

Description

technical field [0001] The invention relates to ship building, in particular to a method for installing a water cannon platform on the general section of a chimney in an ultra-large container ship. Background technique [0002] At present, in order to improve the structural integrity and outfitting integrity of the chimney general section of ultra-large container ships, reduce the amount of high-altitude operations in the later period, and improve the welding quality. In the general ship construction process, the general chimney is completed in the form of a complete hoist. However, since the total height of the chimney section of the ultra-large container ship is nearly 80 meters, this height is close to the limit lifting height of the gantry crane. And the section structure of the chimney on the uppermost floor is relatively weak, so the hoisting rings of the whole section of the chimney are generally arranged on the lower deck, which not only meets the requirements of ho...
