Special bracket applicable to detection on transformer substation hinge pin material

Abstract

The invention relates to a special bracket applicable to detection on a transformer substation hinge pin material. A plurality of support columns are arranged between a surface and a bottom plate; twofixing mechanisms which slide vertically are arranged at an interval in the vertical direction of one support column; a hinge pin to be detected is clamped by the two fixing mechanisms; the upper endof the hinge pin is positioned inside a detection hole; the upper end surface of the hinge pin is parallel to the upper end surface of the surface plate. When the special bracket is used, the hinge pin to be detected is placed inside two clamping rings, a locking bolt is screwed to fix the hinge pin to be detected, the position of a sliding end is adjusted in a vertical direction and fixed by using a fixing bolt, at the moment, the upper end of the hinge pin to be detected is positioned inside the detection hole; the upper end surface of the hinge pin is parallel to the upper end surface of the surface plate, and detection is carried out by using a handheld X-ray direct-reading spectrometer. The problem that the handheld X-ray direct-reading spectrometer is inconvenient in clamping when atransformer substation hinge pin is detected can be solved, hinge pins of multiple different specifications can be fixed and detected, and scientific and effective detection conclusions can be ensured.

Description

technical field [0001] The invention belongs to the technical field of improving the material detection structure of shaft pins, and in particular relates to a special bracket suitable for detection of shaft pin materials in substations. Background technique [0002] Shaft pins are widely used in transmission mechanisms of various substation projects. According to standard requirements, the shaft pins of transmission mechanisms in substations should be made of stainless steel or aluminum bronze. In recent years, the problem of unqualified shaft pin materials has increased. It causes problems such as rusting and fracture, which seriously affects the safety of electric power and has attracted widespread attention. In order to ensure the quality of substation shaft pins, a hand-held X-ray direct-reading spectrometer can be used for detection. However, due to the smooth surface, slender shape and many specifications of the shaft pins, it is extremely inconvenient to detect after...

Problems solved by technology

It caused problems such as rust and fracture, which seriously affected the safety of electric power and attracted widespread attention.

In order to ensure the quality of substation shaft pins, a hand-held X-ray direct-reading spectrometer can be used for detection. However, due to the smooth surface, slender shape and many specifications of the shaft pins, it is extremely inconvenient to detect after on-site disassembly.
