Description

technical field [0001] The invention relates to equipment for a welded pipe process, in particular to a traverse trolley for a UOE welded pipe process production line. Background technique [0002] UOE welded pipe process production line, LOT1 and LOT2 have a total of 109 traverse trolleys, which are responsible for transporting large-diameter welded pipes. In the production process of the welded pipe, the position deviation of the traversing trolley for reclaiming and feeding plays a crucial role in the correct transportation of large-diameter welded pipes, so the positioning accuracy of the traversing trolley is particularly important and meaningful. At present, the traverse trolley mainly drives the wheels to move on the track through the inverter-controlled motor. In order to ensure the accuracy requirements of each station, the traverse trolley is generally equipped with a positioning device, and the common working principle of the positioning device is generally: the ...

AI Technical Summary

Problems solved by technology

[0003] With the acceleration of production rhythm, the currently commonly used traversing trolleys may cause slippage due to factors such as active wheels and track wear, which increases the positioning failure of traversing trolleys

Although the positioning ability can be improved to a certain extent through the program clearing and zeroing functions, it also reduces the on-site production rhythm. The site often reduces slippage failures by spreading flux or welding the surface of the guide rail (the processing time is 2 hours) left and right), but in the water flushing, diameter expansion area and water pressure area of ​​the UOE welded pipe production line, due to the presence of more liquid corrosive media, the wear of the active wheels and tracks of the traversing trolley may be significantly increased

Therefore, it is difficult to reduce the positioning failure rate by a single method of clearing and zeroing

At the same time, because the existing encoder is fixed on the driving wheel, it is also difficult to distinguish electromechanical faults, and often requires multiple checks to confirm
