Embodiment Construction

[0039] The present invention adopts following steps:

[0040] The first step: if figure 1 As shown, after the large upper block 1 has the conditions for installing large equipment 2, a lifting beam 3 is arranged on one side of the large upper block 1;

[0041] Such as figure 2 As shown, the lifting beam 3 is divided into three sections for disassembly and transportation. One end of the lifting beam 3 is designed to match the pin riveting structure of the lifting corbel 6, and the other end is convenient for the fixed anchor hole of the steel strand 9.

[0042] The second step: if image 3 — Figure 4 As shown, a sliding track 11 is fixed by welding on the lifting beam 3, and a slider is placed on the sliding track 11; then, the large equipment 2 is transported as a whole with a hydraulic flatbed transport vehicle and placed on the lifting beam 3 At the same time, a lifting corbel 6 is installed on the top deck girder of the large upper block 1; the lifting corbel 6 is a p...

Abstract

The invention relates to a lifting and sliding mounting technology for platform large equipment. The lifting and sliding mounting technology comprises the following steps of 1, arranging a lifting transverse beam at one side of a large topside; fixing a sliding rail on the lifting transverse beam, and arranging the large equipment on the lifting transverse beam; arranging a lifting corbel; 3, arranging a lifting tower frame at one side of the lifting transverse beam, and arranging lifting jacks on the lifting tower frame and the lifting corbel; 4, arranging a tower frame oblique brace and a guy cable wind rope at one side of the lifting tower frame, and tightening; 5, lifting the lifting transverse beam to the setting height; 6, fixing the lifting corbel and the lifting transverse beam; 7, paving the sliding rail and a slide block on the large topside, arranging a sliding pull jack on the large topside, and sliding the large equipment to the proper position; 8, removing the slide block and the sliding rail, so as to complete the mounting operation. The lifting and sliding mounting technology has the advantages that the large equipment can be mounted on the platform topside without using large floating cranes and large crawler cranes, the operation cost is greatly reduced, and the quality of engineering construction is improved.

Description

technical field [0001] The invention relates to a lifting and sliding installation process for large equipment, in particular to a lifting and sliding installation process for large-scale equipment on offshore oil platform blocks such as oil and gas treatment, living buildings, drilling and workover machines, etc., and belongs to the field of offshore oil engineering . Background technique [0002] Going to deep water is an inevitable trend in the development of the world's petroleum industry. The development of offshore oil engineering to deep water will inevitably make the upper block of the offshore oil platform larger and larger. Then, the large oil and gas processing equipment, living buildings, drilling and workover installed on the platform block The size and weight of machines and other equipment are also increasing, and such large equipment often needs to be installed on land as a whole. [0003] At present, there are the following methods for the land installation...
