Lining defect removal device of cast iron pipe

Abstract

The invention discloses a lining defect removal device of a cast iron pipe. The lining defect removal device comprises a supporting drive assembly, an inserting rod connected with a beating assembly and a rod body drive assembly, a supporting sleeve arranged on the inserting rod in a sliding and sleeving manner, a sliding sleeve arranged on the supporting sleeve in a sleeving manner and a sleeve body drive assembly. A limiting part is arranged on the inserting rod. An abutting connection plate used for being in abutting connection with the limiting part is arranged on the supporting sleeve. Multiple swing parts in abutting connection with the edge of the abutting connection plate are arranged on the sliding sleeve in a hinged manner. When a lining is cleaned, the sliding sleeve is driven by the sleeve body drive assembly to slide, so that the swing parts swing around the hinged point; then, a shaft body drive assembly and the sleeve body drive assembly are used for driving the swing parts to move till the end of each swing part is in abutting connection with a bellmouth, and the inserting rod and the center axis of a pipe body are coaxial; and the pipe body is driven by the supporting drive assembly to rotate, the lining beaten by the beating assembly, the inserting rod is driven by the rod body drive assembly to move, lining defects are removed thoroughly, manual removal is avoided, and product production efficiency and product quality are improved.

Description

Technical field [0001] The invention belongs to the technical field of cast iron pipe production, and more specifically, relates to a cast iron pipe lining defect cleaning device. Background technique [0002] According to the standard requirements of "Nodular cast iron pipes, pipe fittings, accessories and joints for water and gas transmission" and "Nodular cast iron pipes, pipe fittings and accessories for water and gas pipelines", the production of centrifugal nodular cast iron pipes (including sockets and pipes) The inner surface of the pipe body must be coated, and those skilled in the art refer to the coated surface layer as an inner liner. [0003] During the production process, affected by factors such as technology, equipment, and personnel operations, the aforementioned lining surface is prone to defects such as protrusions, dripping, wrinkles, sand leakage, peeling, and blistering, which adversely affect product quality. Reduce the performance of the product. [0004] In...
