Wear detection structure for pumping piping in concrete pumping equipment

摘要

PROBLEM TO BE SOLVED: To certainly prevent any cracking or breakage in force feed piping by detecting, in advance, a leakage of fresh concrete from a detector regardless of the kind of another piping unit connected to a linear piping unit.;SOLUTION: In a concrete pump equipment made for force-feeding fresh concrete through force feed piping 4 by a concrete pump, the force feed piping 4 is equipped with a linear piping unit 4S, and a detector 12 is installed on an outer peripheral surface of an end of the piping unit 4S. When fresh concrete flows through the piping unit 4S, the detector 12 is worn down and burst in advance of the remaining portion of the linear piping unit 4S.;COPYRIGHT: (C)2007,JPO&INPIT
