Ultrasonic automatic checking device of large forging pieces of drum body and sealing head

Abstract

The invention belongs to the technical field of nondestructive detection of large forging pieces such as a nuclear-reactor pressure container, an evaporator and a pressure stabilizer of a nuclear power station and particularly relates to an ultrasonic automatic checking device of large forging pieces of a drum body and a sealing head. The ultrasonic automatic checking device comprises a gate-type guiding rail, a horizontal telescopic rod, a vertical telescopic rod, a rotary platform, a testing-block storage rack, a gong-shaped forging piece, swinging type linear modules and an installation base, wherein the gate-type guiding rail is arranged on the installation base; a sunk round groove is arranged at the middle part of the installation base; the rotary platform is placed in the sunk round groove; the horizontal telescopic rod is arranged in the vertical direction of the gate-type guiding rail and can slide along the vertical direction of the gate-type guiding rail; the vertical telescopic rod is arranged in the horizontal direction of the gate-type guiding rail and can slide along the horizontal direction of the gate-type guiding rail; the swinging type linear modules are respectively arranged at the head parts of the horizontal telescopic rod and the vertical telescopic rod; the gong-shaped forging piece as a detected object is arranged on the rotary platform; and the testing-block storage rack is arranged at the front end in the stroke range of the gate-type guiding rail. The ultrasonic automatic checking device has the advantages that the consistency of data of the processing stage and the following operation-service-inspection procedures of parts is guaranteed and the quality of a product is guaranteed.

Description

technical field [0001] The invention belongs to the technical field of non-destructive testing of large-scale forgings of nuclear reactor pressure vessels, evaporators, and voltage stabilizers of nuclear power plants, and in particular relates to an ultrasonic automatic inspection device for large-scale cylinder and head forgings. Background technique [0002] The primary circuit system of a nuclear power plant contains the high-temperature and high-pressure cooling medium (water) during reactor operation. If the primary circuit system equipment leaks, it will cause unplanned temporary shutdown and cause large economic losses. At the same time, it may cause serious nuclear leakage accidents. Therefore The quality requirements of primary circuit equipment and pipelines are very high. In order to ensure the safety requirements of equipment, a series of relevant inspection specifications have been formulated, and inspection requirements for key equipment have been put forward at...

Problems solved by technology

[0005] Large-scale tubular forgings of nuclear power plants are currently in the factory production stage and are inspected manually. Due to the rapid development of domestic nuclear power plants, large-scale forgings have increased sharply. According to nuclear power-related inspection specifications, these parts need to be inspected during the production and processing stage, and the amount of manual inspection is heavy.

Due to the limitations of manual inspection, there is no data retention, and there are human factors affecting the inspection quality
