Description
Technical field
The invention belongs to the robotization Non-Destructive Testing of narrow space pipeline and container welding, technical field, is specifically related to a kind of narrow space pipeline and container welding checking tool
Background technology
Large pressurized vessel in nuclear power station is as steam generator, voltage stabilizer etc., large scale core level pipeline, if main pipeline, peace note pipe, fluctuation pipe etc. are before the operation of power station and all need its butt-weld to carry out regular Non-Destructive Testing in operational process, there will not be leakage with the heat eliminating medium that ensures the High Temperature High Pressure in circuit system.
Because the large pressurized vessel of nuclear power station all exists radiation in various degree, and size is very large, for reducing personnel's radioactive dose, improves the efficiency detecting, and needs to adopt automation equipment to implement automatically to detect to it.And nuclear power station inner space is limited, and there is possibly arm, step, elbow isostructuralism obstacle near container, pipe welding seam, cause weld seam both sides only to have very narrow passage, hinder the enforcement of weld seam self-verifying.
Therefore, need a kind of narrow space pipeline of development and container welding checking tool structure badly, thereby be applicable to the butt-weld enforcement detection automatically of used in nuclear power station pressure vessel, large scale pipeline.
Summary of the invention
The technical problem to be solved in the present invention is: provide a kind of narrow space pipeline and container welding checking tool, for nuclear power station narrow space pipeline and container butt-weld self-verifying.
In order to realize this purpose, the technical scheme that the present invention takes is:
A kind of narrow space pipeline and container welding checking tool, by forming with lower component: installation base plate, axial stop, circumferential driven unit, circumferential positioning component, probe assembly, axial driven unit, magnet-wheel assembly, scrambler, drive motor;
Installation base plate is the foundation of checking tool, and its two ends connect respectively circumferential driven unit and circumferential positioning component, and intermediate connecting shaft is to driven unit;
Circumferentially driven unit is made up of magnet-wheel assembly and drive motor, and circumferentially positioning component is made up of magnet-wheel assembly and scrambler, and magnet-wheel assembly is used for being with power driven tools along checked container/pipeline outer wall circumferential movement, and testing tool is adsorbed on to container/pipeline outer wall; Drive testing tool circumferentially to walk by drive motor, by scrambler, the circumferential position of testing tool is detected;
Above installation base plate corresponding connect circumferential driven unit and circumferentially the position of positioning component two axial stop are set, and gap between magnet-wheel assembly is across being stuck on circumferential guided way, the instrument that prevents in motion process along checked container/pipeline axial play;
Axially on driven unit, slide block is set, driven unit axially slides up and down vertically, on slide block, arrange and implement the probe assembly that weld seam detects automatically, probe assembly is along the axial enforcement scanning of checked container/pipeline, and by realizing and drive probe assembly along the circumferential scanning of checked container/pipeline with being connected of installation base plate.
Instrument in technical solution of the present invention has very compact structure in the axial direction, can be by only slightly wide than probe scanning stroke scanning passage; Meanwhile, can directly be adsorbed on checked container/pipeline outer wall by magnet-wheel assembly and implement to check, install easily; Can realize Fast Installation and location by aid by the circumferential guided way laying in advance, and the instrument that ensures there will not be in motion process along the undesirable condition of checked container/pipeline axial play; Instrument can be realized by changing the installation base plate of different size (flexibility) the automatic detection of the container/Sizing In Butt Welded Pipes of different-diameter; With checked container/pipeline matched well in the situation that, can, by only exceed the gap of about 100mm than checked container/pipeline outer wall, realize the welding inspection that radially narrow space is pressed.
