Bracket for smoke exhaust pipe of main generator of semisubmersible drilling platform and setting method thereof

Abstract

The invention discloses a bracket for a smoke exhaust pipe of a main generator of a semisubmersible drilling platform which comprises a T-shaped component welded by two pieces of plates; a vertical plate in the T-shaped component is arranged at the upper part and a flat plate is arranged at the lower part; the top end of the vertical plate is welded in the middle of an arch web plate and the lower end surface of the flat plate is arranged on rollers arranged side by side; the rollers are perpendicular to the smoke exhaust pipe to be supported, and the bottom parts thereof are welded on a main structure of the drilling platform or a hull; the flat plate and the end surfaces at both side of the roller are provided with a guiding device formed by two lateral bending irons; vertical plates of the two lateral bending irons are welded and fixed on the main structure of the drilling platform or the hull by the lower end, and transverse plates are limited on the upper end surface of the flat plate of the T-shaped component. The bracket can effectively support the weight of the smoke exhaust pipe, ensures the smoke exhaust pipe to slide in a certain amplitude range, is characterized by simple structure, convenient installation, reliable supporting performance, and small occupying space, and is suitable for being used in occasions that the main generator of the semisubmersible drilling platform or the hull structure has larger quantities of smoke exhaust pipe and the smoke exhaust pipe has larger caliber.

Description

technical field [0001] The invention relates to a bracket, more specifically, to a bracket used to support the exhaust pipe of a generator on a semi-submersible drilling platform; the invention also relates to an installation method of the bracket. Background technique [0002] The number and diameter of exhaust pipes of the main generator of the semi-submersible drilling platform are large, and the layout of the exhaust pipes is very compact due to the limitation of platform space. The conventional smoke exhaust pipe sliding support is usually connected by bolts, and the support is "wrapped" outside the smoke exhaust pipe, thus occupying a large space. When the distance between the smoke exhaust pipes is narrow, or even double-layered, the manufacture and installation of conventional smoke exhaust pipe sliding brackets becomes more complicated, which cannot satisfy the effective support of the smoke exhaust pipes. Contents of the invention [0003] In view of the above p...
