Abstract
The utility model relates to the technical field of concrete conveying pipelines, in particular to a detachable hinge elbow, which comprises a detachable hinge elbow, an outer pipe made of low-carbon steel, a liner pipe made of wear-resistant material, the liner pipe is tightly attached to the inner wall of the outer pipe and comprises a bent liner pipe and a linear liner pipe, the bent end of the outer pipe is provided with a fixed seat, the straight end of the outer pipe is provided with an installation disc, the outer pipe, the fixed seat and the installation disc are of an integrated structure processed by casting, the fixed seat is provided with a detachable flange, and a movable ring is arranged between the flange and the bending liner tube, the utility model changes the traditional manufacturing method of the hinge elbow, when the inner pipe of the hinge elbow pipe is abraded, the hinge elbow pipe can be disassembled, only the damaged inner pipe is replaced, and the enterprise cost is saved.
Description
Technical Field
The utility model relates to a concrete conveying pipeline technical field especially relates to a but hinge return bend of split.
Background
The concrete is prepared by mixing stone aggregate, cement, water and other additives according to a certain proportion. Concrete pumping equipment such as concrete trailer pumps, pump trucks, vehicle-mounted pumps, wet jet machines and the like are generally communicated with a conveying pipe through a hinge elbow in the process of pumping concrete.
The hinge elbow comprises an elbow part, a mounting seat and connecting flanges at two ends, wherein the elbow part comprises an outer pipe and an inner pipe, the outer pipe is made of low-carbon steel, the inner pipe is made of wear-resistant materials, in the prior art, the hinge elbow is welded by the inner pipe and the outer pipe, and then the flanges at two ends and the mounting seat are welded, but in the operation process, when concrete is conveyed, the hinge elbow is subjected to material wear and impact wear at the same time, wherein the faults of wear-through in the middle of an outer arc of an inner layer of the elbow part and breakdown in the middle of the outer arc account for 95% of the faults. Because each part is processed through the welding mode, the hinge return bend all is whole change after wearing and tearing, causes the welding inhomogeneous easily among the welding process, appears welding crack, and the cost of welding is also very high simultaneously.
Disclosure of Invention
An object of the utility model is to prior art not enough, and provide a but hinge return bend of split, its particularity according to the easy damaged position of hinge return bend, when hinge return bend inner tube wearing and tearing, but split hinge return bend, only change damaged inner tube, practiced thrift the cost of enterprises.
The utility model provides a technical scheme that its technical problem adopted is: the utility model provides a but hinge return bend of split, includes the outer tube of low carbon steel material, wear-resisting material's bushing pipe, the bushing pipe with the inner wall of outer tube closely laminates, the bushing pipe includes crooked bushing pipe and sharp bushing pipe, the crooked end of outer tube is provided with the fixing base, outer tube straight line end is provided with the mounting disc, the outer tube the fixing base with the mounting disc is the integral type structure through casting processing, the fixing base is provided with the detachable flange, the flange with be provided with the expansion ring between the crooked bushing pipe.
Preferably, the linear liner is an interference fit or an over fit with the inner wall of the outer tube.
Preferably, the curved liner is a clearance fit with the inner wall of the outer tube.
Preferably, the end of the linear liner is provided with a wear sleeve.
Preferably, the outer circumference of the end of the linear liner is provided with a fixing ring.
The utility model has the advantages that: the utility model provides a but hinge return bend of split, its includes the hinge return bend of a split, outer tube, the bushing pipe of wear-resisting material including low-carbon steel material, the bushing pipe with the inner wall of outer tube closely laminates, the bushing pipe includes crooked bushing pipe and sharp bushing pipe, the crooked end of outer tube is provided with the fixing base, outer tube sharp end is provided with the mounting disc, the outer tube the fixing base with the mounting disc is the integral type structure through casting processing, the fixing base is provided with the detachable flange, the flange with be provided with the loose ring between the crooked bushing pipe, the utility model discloses change the preparation method of traditional hinge return bend, when hinge return bend inner tube wearing and tearing, but split hinge return bend only changes damaged inner tube, practiced thrift the cost of enterprises.
