The invention relates to a novel driving device for a storage base plate magnetic leakage scanning detector, which mainly solves the problems that the driving device on the prior magnetic leakage scanning detector causes that the detector has low detection precision, manual detections cannot be realized and detection blind zones are large. The novel driving device is characterized by consisting of a motor (20), a worm and worm wheel reducer (18), a driving wheel (19), a main connecting frame (21) and a pneumatic hold-down mechanism, wherein the motor (20), the worm and worm wheel reducer (18)and the driving wheel (19) are fixed on a retaining plate of a Z-shaped reducer fixedly connected with the main connecting frame (21), and the retaining plate can move up and down along with the pneumatic hold-down mechanism. The driving device has the characteristics of ensuring high detection precision for the detector, realizing the manual detections and reducing the detection bind zones.
Description
Technical field: [0001] The invention relates to a power part used in a magnetic flux leakage scanning detector in the field of non-destructive testing, in particular to a new driving device used in a magnetic flux leakage scanning detector on a storage tank bottom plate. Background technique: [0002] In the petroleum and petrochemical industry, storage tanks are important tools for containing crude oil, intermediate oil and refined oil, petrochemical products, various gases and petrochemical raw materials. Due to the complex physical and chemical properties of the medium contained in the storage tank, it will have a great corrosion effect on the material of the storage tank and the pipeline, which will cause one or another defect in the production and operation of the storage tank, which will affect the safety of the storage tank and the entire production system. The safe operation of the system poses a major threat. Moreover, a large proportion of storage tanks in servic...
