Description

Technical Field

[0001] The utility model relates to the technical field of seamless steel pipe sorting devices, and more specifically to an online detection and quality control device for seamless steel pipes. Background Art

[0002] Seamless steel pipe is made by perforating a whole round steel. There is no weld on the surface of the steel pipe, which is called seamless steel pipe.

[0003] At present, seamless steel pipes are subjected to non-destructive testing and outer diameter testing during the production and transportation process. However, unqualified steel pipes must be transported to the sorting device for centralized sorting. Not only do the staff need to wait for the sorted unqualified steel pipes to be processed, but the steel pipes that fail the outer diameter test must also be sent to the non-destructive testing device for testing, which wastes time and reduces work efficiency.

[0004] For example, announcement number CN205436343U discloses an online steel pipe inspection and sorting device, which includes: a loading mechanism for stacking and loading steel pipes to be inspected, a sorting mechanism for stacking and sorting inspected steel pipes, a conveying mechanism for conveying the steel pipes from the loading mechanism to the sorting mechanism, and a control mechanism.

[0005] It can be seen from the above-mentioned public scheme that the sorting mechanism is located at the end of the conveying mechanism, so the steel pipes with unqualified sizes need to enter the eddy current flaw detector for inspection, and then be conveyed to the sorting mechanism for centralized sorting and stacking. During the operation of the device, the staff cannot deal with the sorted unqualified steel pipes in time, which reduces work efficiency. Utility Model Content
