AI Technical Summary
Existing large pump and valve box repair devices with center positioning lack stable support during the repair process, which makes the repair tools prone to vibration or displacement. Especially when dealing with large-area wear or high-hardness materials, it is difficult to maintain surface flatness and dimensional accuracy, affecting repair quality and equipment life.
The system employs a linkage mechanism that uses a cylinder to drive a sliding column, which in turn drives a rotating arm and a grinding plate. Combined with a telescopic rod, it provides stable support. A motor-driven gear and rack meshing transmission enables height adjustment of the support column, and a positioner ensures center positioning, guaranteeing repair accuracy and stability.
By providing stable support and precise positioning, vibration and displacement during the repair process are reduced, improving repair quality and equipment lifespan. It is particularly suitable for the repair of large-diameter or different-diameter pump and valve boxes, improving repair efficiency and automation.
