Embodiment Construction

[0016] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0017] like figure 1 , figure 2 As shown: the non-destructive testing ultrasonic probe universal joint tray is composed of probe carrier 1 and probe tray 2. The main body of probe carrier 1 is a sphere with a square hole in the middle for installing probe 8. The square hole is in the same shape as probe 8 Matching, the probe 8 is fixed to the probe carrier 1 through two rotating set screws 4 symmetrically arranged on the probe carrier 1. There is a probe tray 2 outside the probe carrier 1, and the probe tray 2 is a semi-closed structure composed of a cylinder. The probe carrier 1 is installed at the opening of its upper end, and the lower end of the probe carrier 1 has a certain distance from the bottom surface of the probe tray 2. The probe carrier 1 cooperates with the cylindrical side of the probe tray 2 to form a universal structure, so that the probe 8...

Abstract

The invention belongs to the field of ultrasonic nondestructive inspection of nuclear power station small-inner diameter tubular equipment, and discloses a nondestructive inspection ultrasonic probe universal joint pallet. The nondestructive inspection ultrasonic probe universal joint pallet is characterized in that a probe carrier and a probe pallet compose a universal structure so that a probe can rotate with the probe carrier towards all directions in the probe pallet to adapt to the change of a detected surface; through a spacing structure of the probe carrier and the probe pallet, the probe carrier can move up and down in the probe pallet along a probe pallet guide groove and can also rotate around a rotating fastening screw as a rotating shaft; and a compacting force produced by a spring is power for realizing the probe carrier universal function, and through the power, the probe carrier can automatically adapt to the change of the detected surface thereby closely clinging to the detected surface. The nondestructive inspection ultrasonic probe universal joint pallet overcomes the defect that the prior art cannot be utilized for small-diameter connection pipes and other similar tubular equipment, and improves detection accuracy and reliability.

Description

technical field [0001] The invention belongs to the technical field of ultrasonic non-destructive testing of small-diameter tubular equipment in a primary circuit system of a nuclear power plant, and in particular relates to a universal joint tray of a non-destructive testing ultrasonic probe. Background technique [0002] In the primary circuit system of a nuclear power plant, there are many small-diameter connecting pipes. Because this area is in a state of high temperature and high pressure for a long time, and a cooling medium with high radioactivity flows through it, if there is leakage in this area, a serious safety accident will occur. Therefore, The takeover welds and safety end welds of these takeovers must be inspected regularly. Ultrasonic inspection of these welds using automated equipment is a common and important means. In the process of implementing ultrasonic automatic inspection, the bonding and pressing condition of the probe and the surface to be inspecte...
