At this time, the connecting rod 504 rotating at the eccentric part of the eccentric wheel A503 starts to perform circular motion, so that the connecting rod 504 drives the eccentric wheels B505 rotating at both ends thereof to rotate synchronously, thereby driving the scraper 507 fixedly connected thereto to rotate synchronously through the eccentric wheel B505. At the same time, during the linear motion of the pedestal 501, the scraper 507 can cyclically contact the welded steel pipe and scrape off the welding slag thereon.

[0048] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.

[0049] The fixed connection referred to in this application refers to a connection in which a part or component is fixed without any relative movement, which can be divided into detachable connection and non-detachable connection.

[0050] (1) Removable connection: The parts are fixed together by screws, splines, wedge pins, etc. This connection method can be disassembled for maintenance without damaging the parts. However, the specifications of the connectors used must be correct (such as the length of the bolts, keys, and wedge pins) and they must be properly tightened.

[0051] (2) Non-detachable connection: mainly refers to welding, riveting and tenoning. Since forging, sawing or oxygen cutting are required for disassembly during maintenance or replacement, spare parts generally cannot be reused. At the same time, attention should be paid to process quality, technical inspection and remedial measures (such as calibration, polishing, etc.) during connection.

[0052] The sliding connection referred to in the present application means that the component can slide along a linear trajectory, and the hinged connection referred to in the present application means that the component can rotate along an axial constraint.

[0053] In some cases, the sliding connection and hinge referred to in the present application may also be damped so that the components have the ability to maintain a desired position.

[0054] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
