Flexible support method of curve surface

Abstract

The invention adopts hydraulic support columns to form an array to support a curved object. The hydraulic support columns in the array are partitioned and supported by three points to apply a static balance principle; the hydraulic support columns within a supporting range are partitioned into areas according to a three-point support principle; bearing work cavities of all hydraulic cylinders in each area are mutually communicated through pipelines, and the communicated support columns are like a ball hinge, namely a total pivot, to the ground although the support columns support a supported object at a plurality of points, so that the independent three sub-areas are like three points to support. The support columns in the array are divided into two large areas like a badminton court; each large area is divided into three small areas and respectively supports two curve steel plates, and the total volume of the hydraulic support columns in each sub-area is controlled to adjust the gesture, so that the butted edges are aligned. The area division is controlled by a control valve and is carried out according to the size and position of the supported object, and the middle and boundary positions can be conveniently adjusted.

Description

technical field [0001] The invention relates to a supporting method for large-scale object operations, in particular to the supporting of curved steel plates in the segmental manufacturing of large-scale ship hull curved surfaces. Background technique [0002] At present, it is easiest to use 3-point support for supports similar to curved surfaces when the rigidity of the supported body is good. For large-area curved steel plates, the length and width dimensions are much larger than the thickness, and the deformation of 3-point supports is relatively large. Multi-point support is often used. Support, the height adjustment of the support point is adjusted manually, which is very inconvenient. The published invention application "multi-point floating flexible support device" (CN2011101072535) is a relatively convenient support, but due to the buoyancy of the pillar, it is only suitable for The support of lighter objects has a narrower use area.
