Tool for detecting shape and position dimension of U-shaped groove of super-large-diameter foundation ring plate

Abstract

The invention relates to a tool for detecting the shape and position size of a U-shaped groove of a super-large-diameter foundation ring plate. The base ring plate is arranged on one side of the container, and the detection part is located on one side of the base ring plate. A plurality of U-shaped grooves are formed in the peripheral side of the basic annular plate; the detection part comprises a base and an angle scale hinged to the top of the base. The base is placed on the plane, the angle ruler is rotated to enable the centering round rod to be inserted into the U-shaped groove, the scale distance L of the center of the centering round rod on the angle ruler is read, meanwhile, the angle ruler is used for measuring the included angle A between the angle ruler and the base, data are recorded, and the whole circle of U-shaped groove of the foundation ring plate is measured. By means of the detection mode, errors caused by manual measurement are reduced, waste of equipment resources caused by detection through a machine tool is avoided, and the detection cost is greatly reduced.

Description

technical field [0001] The invention relates to the technical field of detection tools, in particular to a detection tool for the shape and size of a U-shaped groove of an ultra-large-diameter foundation ring plate. Background technique [0002] There are generally two detection methods for the shape, position and size of the U-shaped groove on the existing foundation ring plate. Manual detection: manual use of a tape measure or a tape measure, two people stretch the tape measure, directly read data and machine tool detection: the pressure vessel is placed on the On the machine tool table, the basic ring plate faces the main shaft of the boring machine, and the shape and size of the U-shaped groove on the basic ring plate are measured by the machine tool walking. [0003] At present, manual detection: Since the center point of the circumferential hole is a spatial point, it cannot be actually determined, which will cause the diameter center point of each measurement to fail ...

AI Technical Summary

Problems solved by technology

[0003] At present, manual detection: since the center point of the circumferential hole is a spatial point, it cannot be actually determined, which will cause the diameter center point of each measurement to fail to coincide during manual detection, resulting in inaccurate shape and size of the U-shaped groove

Machine tool inspection: Since the diameter of the super-large-diameter base ring plate is usually greater than 5 meters, or even 10 meters, the overall tonnage of the corresponding pressure vessel is overweight and the size is too large, so that the vessel cannot be lifted and placed on the machine tool table; and it is suitable for this kind of measurement tool However, the resources of the machine tool equipment in the situation are less, and even if there are, the on-site operation workload is heavy and time-consuming, which will also occupy machine tool resources and delay other more important production tasks.
