Problems solved by technology

As the assembly of the two takes a long time (at least 2 hours), and there are many workers on site, there is an increase in personal safety hazards; in addition, the disassembly and reassembly of the air cooler will affect the sealing of the contact surface between the two Sexuality, causing scavenging air leakage, and also causing hidden dangers of garbage entering the interior of the air cooler

Embodiment

[0032] The implementation of the method of the present invention will be described in detail below by taking the overall shipping and hoisting process of the main engine cylinder block and air cooler of a 76,000-ton bulk carrier.

[0033] The main engine model in this embodiment is: 5S60MC-C, the gross weight of the cylinder block 01 and the air cooler 02 assembly: 131.8T ​​(with special bracket 03); external dimensions: 8700×7500×7600 (length×width×height); center of gravity Position: 2185mm axially from the centerline of 1# cylinder (toward the thrust end), 291mm laterally from the centerline of the cylinder body (toward the exhaust side), and 4000mm from the bottom of the special bracket 03 (the height of the special bracket 03 is 2500mm); Lifting point layout: 1# cylinder and 5# cylinder (lifting point opening 4080mm).

[0034] In this embodiment, the main engine cylinder block 01 and the air cooler 02 are shipped and hoisted as a whole, as follows:

[0035] Step 1: Disas...

Abstract

The invention discloses a method for integrally hoisting a marine main engine cylinder body and an air cooler. The method includes: (1), when a main engine is disassembled, the cylinder body and an air cooler assembly are placed on a special bracket; (2), oil seal is carried out on the lower flat surface of the main engine cylinder body to be ready for being transported ; (3), integrally, the main engine cylinder body and the air cooler assembly together with the special bracket are hoisted on a flat car; (4), after transported to a slipway, the oil seal of the lower flat surface of the main engine cylinder body is removed and the lower flat surface of the main engine cylinder body is cleaned on the flat car; and (5), the cylinder body and the air cooler assembly are hoisted on a main engine rack to be assembled. The invention further provides the special bracket used for the method. By utilization the special bracket, the whole hoisting and shipping of a main engine are achieved, the processes of disassembling and assembling the cylinder body and the air cooler assembly are saved, the utilization efficiency of a hoisting device is improved, meanwhile the assembling quality of the main engine is guaranteed, the labor intensity of workers is relieved, and safety potential hazards of site work are reduced.

Description

technical field [0001] The invention relates to a method for hoisting a main engine of a ship, in particular to a bracket and a method for integrally hoisting a cylinder body of a main engine of a ship and an air cooler, and belongs to the technical field of ship building. Background technique [0002] After the main engine of the ship is manufactured, it must be hoisted to the berth for installation. For the heavy-duty main engine of a large ship, its hoisting and transportation are difficult tasks. Since the air cooler and the auxiliary blower assembly of the main engine are located below the cylinder block, and they do not have a unified landing plane, the existing means of transportation cannot meet the needs of the overall transportation of the two. Existing methods can only disassemble the air cooler from the main engine in the heavy machinery assembly workshop and transport it separately, and then assemble it by the assembly department after arriving at the assembly s...
