A universal support suitable for fixing a portable indenter in a pipeline structure

Abstract

The invention discloses a universal bearer for fixing a portable indenter in a pipeline type structure. The universal bearer includes a bear panel, an axial fixing assembly for fixing a surface of the pipeline type structure, radial guide assemblies, connection members for connecting a base of the portable indenter, and a controller; an opening for testing the pipeline type structure is formed in the center of the bearer panel; the connection members are symmetrically arranged on the upper surface of the bearer panel at the front side and the back side of the opening; the radial guide assemblies are symmetrically arranged on the left side and the right side of the bearer panel; the controller is arranged on the bearer panel; and each radial guide assembly includes a guide rail, a clamping claw connector, a clamping claw, a horizontal driving mechanism for driving the clamping claw to move horizontally, and a vertical telescoping mechanism for allowing the clamping claw to stretch vertically. The universal bearer for fixing the portable indenter in the pipeline type structure can meet the environment demands of different project sites.

Description

technical field [0001] The invention relates to a universal support suitable for fixing a portable indenter in pipeline structures. Background technique [0002] Instrumented indentation is a microscale mechanical testing system. With nearly 30 years of development, instrumented indentation testing technology has achieved great results. Micro / nano indentation / scribing instruments suitable for laboratory conditions have achieved high precision and can meet the needs of testing. At the same time, portable indenters that can be applied to in-situ testing at engineering sites have also appeared, and have been applied in online testing of large structural parts, bridges, tracks, oil and gas pipelines, oil storage tanks and other projects, and have broad development prospects. [0003] However, when the currently existing portable indentation instruments are tested for pipeline structures, because the size and diameter of the pipelines are different, the pipeline structures with ...

Problems solved by technology

[0003] However, when the currently existing portable indentation instruments are tested for pipeline structures, because the size and diameter of the pipelines are different, the pipeline structures with different diameters are tested for different engineering sites or the same engineering site. When it is necessary to replace or redesign a new fixed support to meet the engineering requirements, this not only wastes huge resources but also affects the progress of engineering testing and reduces work efficiency
