Probe tray clinging structure for ultrasonically inspecting inner walls of containers

Abstract

The invention relates to the field of technologies for ultrasonically inspecting the insides of nuclear power plants, and particularly discloses a probe tray clinging structure for ultrasonically inspecting the inner walls of containers. The probe tray clinging structure comprises connecting rod supports A, sliders, guide shafts, connecting rods and two extension arms. The two extension arms are symmetrically arranged at a 180-degree angle, and each extension arm is connected with the corresponding connecting rod support A by a hinge pin A and can swing around the connecting rod support A; one end of each connecting rod is connected with a connecting rod support B in the middle of the lower end of the corresponding extension arm by a hinge pin B, the other end of each connecting rod is connected with the corresponding slider which sleeves the corresponding guide shaft, the sliders can linearly move along the guide shafts to drive the connecting rods to swing, and the extension arms further can be driven to rotate around the connecting rod supports A to be unfolded. The probe tray clinging structure has the advantages that the extension arms are symmetrically arranged, accordingly, radial reacting force which is applied onto equipment by the walls of the containers via probe trays can be offset, working conditions of the equipment can be improved, and the stability of the equipment can be enhanced.

Description

technical field [0001] The invention belongs to the technical field of ultrasonic inspection inside a nuclear power plant, and in particular relates to a bonding structure of a probe tray for ultrasonic inspection on the inner wall of a container. Background technique [0002] In industrial production, metal containers of various specifications are more and more widely used. On the one hand, the weld on the metal container is prone to defects such as bubbles, cracks, and slag inclusions after welding, and the defective weld is prone to corrosion at the defect, and the corrosion slowly expands to cause leakage of the medium in the container; on the other hand, the container is long Time running is prone to aging and degradation. Thereby affecting industrial production, serious accidents will occur, so the container must be checked regularly. [0003] When performing ultrasonic inspection on the inner wall of the container, the bonding effect of the probe tray is directly re...
