Abstract

The invention relates to a rigid multi-leg supporting and centering structure with the supporting radius being adjustable. The rigid multi-leg supporting and centering structure comprises a supporting leg fixing rack and a plurality of supporting leg assemblies, wherein the supporting leg assemblies are fixed to the outer side of the supporting leg fixing rack in the circumferential direction and spaced at a uniform angle in the circumferential direction. Each supporting leg assembly comprises a worm wheel and worm supporting leg assembly. Each worm wheel and worm supporting leg assembly comprises a supporting leg pipe and a worm wheel and worm assembly. One end of the inner side of each supporting leg pipe is fixed to the outer side of the supporting leg fixing rack. Each worm wheel and worm assembly is arranged at the outer end of the corresponding supporting leg pipe. Each worm wheel and worm assembly comprises a lead screw, a worm wheel and a worm. Each lead screw penetrates into the corresponding supporting leg pipe from the outside of the supporting leg pipe. Each lead screw penetrates through the corresponding worm wheel, the lead screw and the worm wheel are limited in the circumferential direction, and the lead screw and the worm wheel are in sliding fit in the axial direction. Each worm wheel is engaged with the corresponding worm. By the adoption of the rigid multi-leg supporting and centering structure with the supporting radius being adjustable, automatic detection and maintenance of pipelines and containers with different inner diameters can be achieved, and fixation of automatic detection and maintenance equipment in the pipelines and the containers with different inner diameters and the alignment between the equipment and the pipelines are guaranteed.

Description

technical field [0001] The invention relates to the technical field of nuclear engineering, in particular to a rigid multi-leg support centering structure with adjustable support radius. Background technique [0002] In industrial production, pipes and containers of various specifications are more and more widely used. Pipes and containers are prone to defects such as bubbles, cracks, and slag inclusions after metal welding. Defective welds are prone to corrosion at the defect. Slowly expand the medium in the pipeline and the container to leak, and the aging phenomenon of the pipeline and the container is easy to reduce after a long time of use. As a result, industrial production will be affected and serious safety accidents will occur. Therefore, pipelines and containers must be inspected and maintained regularly. [0003] In accordance with the requirements of relevant inspection specifications, in order to realize the automatic inspection and maintenance of pipes and con...
