Problems solved by technology

[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 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 Support for lighter objects with a narrower surface

Embodiment Construction

[0015] The center line is different from the center line. The center line is the geometric center axis of the entire array. There are two geometric center lines in a rectangular array, which are perpendicular to each other. The specially emphasized "court center line" refers to the line between the left and right service areas, and the unemphasized center line refers to the ball. The line where the net is located, the two areas separated by the midline are called field areas, and their sizes are equal. The midline is the dividing line between the two supported objects, and its position can be adjusted near the midline. The area divided by the midline is Two, called the work area, the work area includes the front area, the rear left area, and the rear right area. The size of the work area depends on the size of the supported object, and the area connected by the connector is called the action area.

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.
