[0036] A kind of three fulcrum measuring method of ship's current school management, when the three fulcrum measuring mechanism 9 adopts the scheme A, the specific steps are as follows:

[0037] 1. Use the first screw, the second screw 5-2 and the appropriate first flange pad and the second flange pad 4-2, through the threaded first slider 3-1, the second slider 3 -2 Connect the measurement base plate 2 to the flange surface to be measured;

[0038] 2. Adjust the position of the measuring base plate 2 so that the scales indicated by the first slide block 3-1 and the second slide block 3-2 are consistent. At this time, the center of the measuring base plate 2 coincides with the center of the flange. Tighten the first screw and the second screw 5-2 to fix the measuring bottom plate 2 well.

Abstract

The invention provides a three-fulcrum measurement method and a measurement device for a ship-straightening tube. A pull rope displacement sensor is arranged. Started from three fixation points of a measurement bottom plate fixed on the surface of a flange, the lengths from the three fixation points to the central points of three screw holes in another flange are measured respectively. Through the calculating process, the relative spatial position between the two flanges can be obtained. The pull rope displacement sensor is fixed on the measurement bottom plate and the measurement bottom plate is fixed on the surface of one flange via two slidable sliding blocks provided with screw threads. A three-fulcrum measurement mechanism is arranged on the measurement bottom plate. A pull rope comes round a steering wheel and a guide wheel to be steered and then passes through grooves in support posts. Clamping rings can be temporarily fixed on three support posts. The central points of the upper ends of the support posts form three fulcrums. The pull rope displacement sensor respectively measures the lengths from the three fulcrums to three screw holes in another flange. The measurement method is simple and high in measurement accuracy. The measurement device is light in weight, convenient to carry about and low in cost.

Description

technical field [0001] The invention relates to the measurement technology of ship's current school management in the field of shipbuilding, in particular to a measurement method and a measuring device for ship's current school management. Background technique [0002] Modern ships are mostly manufactured in sections. When the subsections or total sections are closed, the pipelines between them need to be connected by pipes. Due to errors in both the manufacturing process and the installation process, the connecting pipes processed according to the original design drawings often cannot be installed smoothly. At present, domestic and foreign shipyards generally adopt the method of current school management (also known as on-site sampling pipe, closing pipe, or profiling pipe) for processing. That is, use angle iron to weld and position the matching flange on site, and then move the model to the infield, and have experienced masters take samples and measure them to obtain pr...
