Description

Technical Field

[0001] This utility model belongs to the field of pipe pile steel mold technology, specifically, it relates to a replaceable roller structure for pipe pile steel mold. Background Technology

[0002] Pipe pile steel molds are standardized molds made of high-strength steel through welding and processing. They are mainly used for pouring concrete and producing prestressed concrete pipe piles with circular cross-sections that meet national standards through prestressing tensioning. Their core function is to ensure that the concrete maintains its designed shape and dimensions during the forming process and withstands the external forces exerted during tensioning, centrifugation, and steam curing. The rollers on the outer ring of the pipe pile steel mold are components that facilitate mounting on centrifugal equipment to drive its rotation. These rollers are usually welded to the outer ring of the pipe pile steel mold, making them non-removable and unable to be repositioned. Welding pipe pile steel molds of varying lengths to accommodate centrifugal equipment also increases costs. To improve ease of use and reduce costs, a replaceable roller structure for pipe pile steel molds is provided. Utility Model Content
