Problems solved by technology

[0002] At present, in ship construction, the installation of large-scale equipment bases adopts a trial-fitting installation, that is, the base is manufactured in excess, and it is hoisted to the site for manual measurement, marking, manual trimming, and repeated positioning adjustments to ensure that the base The installation accuracy of the seat is heavy, and the construction accuracy depends entirely on the experience of the workers, which will lead to the gap between the base and the installation surface being out of tolerance. equipment installation
As ships, especially ships, have stricter requirements for vibration and noise reduction of power equipment, the installation accuracy of the base is also getting higher and higher. It is difficult to guarantee the installation accuracy with the traditional trial installation, and the construction environment is harsh. , the construction efficiency is low, and it does not conform to the development direction of lean shipbuilding

Embodiment Construction

[0018] The technical solutions of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Apparently, the described embodiments are some of the embodiments of the present invention, but not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0019] A method for installing the base of large-scale marine equipment without margin, for details, see figure 1 , which differs from the prior art in that: the installation steps are as follows: a. measure the manufacturing accuracy of the large-scale equipment base itself, and determine the basic size of the equipment base; b. draw the center line of the base and the For the installation line of the seat web and the bracket, paste the target piece at the intersection of the web and the bracket as a mark poi...

Abstract

The invention relates to a no-allowance installing method for a marine large equipment base. The installing position of the equipment base on a deck is measured by a full-station scanner, coordinate system transformation is conducted through gauge points, measured point cloud data are matched with a design model, slicing is conducted on the point cloud data with base webs and a bracket plane, anddata of an installing allowance line for butt joint of the lower end of the base and the deck are calculated; according to the installing allowance line obtained through calculation, allowance cuttingis conducted on all webs and brackets at the lower end of the base; and finally the no-allowance base is directly located and installed, and base welding work is completed after a base panel is retested and the effect that flatness meets precision requirements is determined. Through the no-allowance installing method, the problem of the influence of deck flatness error on base installation is solved effectively, an installing intersecting line at the lower end of the large equipment base can be measured precisely, and precise cutting of the installing allowance is conducted once.
