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 described below in conjunction with the drawings, which is apparent from the accompanying drawings. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art are in the range of the present invention without making creative labor premise.

[0019] One kind of large marine device mounting method no margin base, see in particular figure 1 , Which differs from the prior art in that: steps are as follows: a, large equipment manufacturing precision measurement of the base itself, determine the basic size of the apparatus base; B, the position of the base platform mounting base shown and machine centerline mounting line of the base web and the toggle plate, at the intersection of the web and the toggle plate adhesive sheet as a target marker; C, using the total station scanner, the coordinate system is determined, on the base mounting surface for scanning measure...

Abstract

The invention relates to a method for installing a large-scale marine equipment base without margin. A total station scanner is used to measure the installation position of the deck where the equipment base is located, and coordinate system transformation is performed by using marked points, and the measured point cloud data and the design model are compared. After matching, slice the point cloud data of the base web and bracket plane, and calculate the data of the installation allowance line connecting the lower end of the base with the deck; according to the calculated installation allowance line, execute the base Each web plate and bracket at the lower end shall be cut for allowance; finally, the base without allowance shall be directly positioned and installed, and the welding of the base shall be completed after retesting the base panel and confirming that the flatness meets the accuracy requirements. The invention effectively solves the influence of the base installation deck flatness error, enables the installation intersecting line at the lower end of the large equipment base to be accurately measured, and the installation margin is accurately cut at one time.

Description

Technical field [0001] The present invention relates to the technical field of equipment installation, in particular a large marine apparatus of the base is no remaining mounting method. Background technique [0002] Currently ship construction, the mounting base for large equipment are used with the test installation, i.e. the base for the remainder of the manufacturing site crane to manual measurement, scribing, cutting artificial repair, repeatedly adjusted positioning to ensure yl method seat mounting accuracy, a large workload, the construction accuracy is completely dependent on the experience of workers, resulting in the base and the mounting surface of the tolerance gap, the welding installation is easy to form the base of the secondary deformation, so that the base panel sagging or bend is not conducive to installation of equipment. With particular ship ship vibration and noise reduction requirements of the power plant more strict mounting accuracy is increasingly high b...
