Embodiment 1

[0019] Firstly, the frame of each layer is made and the frame is fixed into the frame body 1 by using diagonal braces; secondly, the pipe fittings and pipe supports are installed in the frame body to make the chimney unit 3 and transported to the construction site; the chimney unit 3 is transported to the construction site; The whole is hoisted into the chimney section 2 to make a chimney unit module.

[0020] The chimney unit includes a main engine exhaust pipe, a generator exhaust pipe, a boiler exhaust pipe, an oil and gas pipe ladder, a frame and an electrical outfitting. There is a fixing device in the chimney section 2 to connect and fasten the chimney unit 3 .

Embodiment 2

[0022] First, make the frame of each layer and fix the frame into the frame body 1 by using diagonal braces; secondly, install the pipe fittings and pipe brackets into the frame body to make the chimney unit 3 and transport it to the construction site; install the rollers under the chimney unit 3 4. Install a pair of guide rails 5 on the inner surface of the chimney unit 3, first use a crane to hoist the chimney unit 3 onto the guide rails of the chimney section 2, and then slowly pull the chimney unit 3 into the chimney section 2 to form a chimney unit module.

[0023] The chimney unit includes the exhaust pipe of the main engine, the exhaust pipe of the generator, the exhaust pipe of the boiler, the oil and gas pipe ladder, the frame or the electrical outfitting, and there is a fixing device in the chimney section 2 to connect and fasten the chimney unit 3, and the chimney After the unit 3 is pulled into the chimney section 2 through the guide rail 5, the roller 4 is removed...

Abstract

The invention relates to a manufacturing process for a shipping chimney unit module, which comprises the following steps of: manufacturing each layer of frame, and fixing the frames into a frame body by utilizing an inclined strut; arranging a pipe outfitting piece and a pipe support in the frame body to form a chimney unit, and conveying the chimney unit to a construction site; and hoisting the chimney unit in chimney subsections integrally by utilizing a hoist to form a chimney unit module or arranging a roller below the chimney unit, arranging a pair of inner guide rails on the inner surfaces of the chimney subsections, hoisting the chimney unit to the guide rails of the chimney subsections by utilizing the hoist, and pulling the chimney unit in the chimney subsections slowly to form the chimney unit module. The manufacturing process has the advantages that: 1, for iron outfitting pieces in the subsections, the original subsection preassembly is changed into module manufacturing ina workshop, the closed construction environment is changed into the opened construction environment, and the labor environment of workers is improved greatly; 2, the construction efficiency is improved greatly, the original outfitting operation is not started until the cooperation subsections are conveyed to a plant, but the outfitting operation and subsection manufacturing can be constructed simultaneously at present, so the period of subsection integrity is shortened; 3, the construction cost is reduced, the outfitting operation is transferred to the module workshop from an external field, so the time for renting a truck crane on the external field is reduced greatly, and the cost is saved; and 4, processes are advanced, the outfitting pieces are subjected to modular manufacturing, and the preassembly operation is advanced to unit manufacturing.

Description

technical field [0001] The invention relates to a manufacturing process of a ship chimney module unit. Background technique [0002] The ship chimney is a tubular building that guides the smoke generated by the ship to high altitude. During the ship manufacturing process, its overall structure and the volume of the chimney need to be controlled to achieve better exhaust effect. The existing installation method is segmented installation. The construction department installs the pipe base, shelf structure, exhaust pipe and silencer in the chimney respectively for segmental construction. The pre-installation of chimney inner pipes, pipe bundles, mufflers, bases, brackets, etc. in the installation area has the disadvantage of requiring uninterrupted hoisting and coordination. Compared with other types of segmented pipe pre-outfitting, the working conditions are poor. For the hoisted grid shelf, the exhaust pipe must be equipped with multiple hoists at different positions on the...
