Installation method of large oil cylinder

Abstract

The invention provides a mounting method of a large oil cylinder, which comprises the following steps: S1, placing the large oil cylinder on a supporting seat, and fixing the large oil cylinder, so that the large oil cylinder cannot deviate on the supporting seat; s2, the lifting platform is fixed through a hoisting tool before hoisting; s3, the crane moves the lifting platform to the position over the large oil cylinder through a hoisting tool; s4, the lifting platform is adjusted through a hoisting tool, so that the lifting platform and the large oil cylinder are in an installable posture; and S5, the large oil cylinder is fixed to the installation part of the bottom of the lifting platform, and therefore installation of the large oil cylinder is completed. According to the method, the number of matched work types is small, the number of workers is small, the work such as hanger welding and hanger cleaning is omitted, the overall operation time is shortened, the installation efficiency is greatly improved, and the ship building period is shortened.

Description

technical field [0001] The invention relates to the field of ship construction, in particular to an installation method of a large oil cylinder. Background technique [0002] There are ro-ro equipment on ships of ro-ro equipment. There are many types of ro-ro equipment, including springboards, lifting platforms and inner slopes, movable car decks, large ro-ro doors, etc. Among them, lifting platforms are extremely important ship ro-ro equipment. [0003] The operating cylinders of the existing ro-ro passenger ship lifting platform are installed in the lifting platform. The size of the lifting platform is relatively long, and the length and width are usually between 15-20 meters. The operating cylinders in the lifting platform are all large cylinders. The method of installing the large operating oil cylinder in the lifting platform is as follows: place the lifting platform stably with the support column, then install the corresponding hanging code at the installation position...

AI Technical Summary

Problems solved by technology

[0004] The existing method of installing the oil cylinder requires a lot of preparatory work and takes a long time. It needs to clear a relatively open site, and then build a special support column to erect the lifting platform, so as to facilitate the installation of large oil cylinders on the lifting platform. At the bottom, in order to prevent the lifting platform from being deformed during the erection process, it is necessary to build a specific support column to erect the lifting platform, and then weld the hoisting code at the bottom of the lifting platform to lift the oil cylinder. The disadvantages are:

[0006] 2. Multi-person cooperation is required: 4 lifting workers (responsible for moving the hoist and operating the oil cylinder to the installation position), 4 fitters (responsible for installing and operating the oil cylinder and cooperating with the lifting worker, working together for 8 hours);

[0008] There is a lot of preparatory work in the early stage; there are many types of work that need to be coordinated, a large number of people, long operating hours, and low efficiency. Only the preparation work before hoisting takes about half a month, resulting in a longer ship construction cycle
