Central plate link chain of chain bucket type hoister

Abstract

The invention provides a central plate link chain used for a chain bucket elevator, comprising a mandrel, a sleeve sheathed on the outside of the mandrel, and outer scraping belts and inner scraping belts which are sheathed on the sleeve. The central plate link chain is characterized in that a central sleeve is sheathed in the middle of the mandrel; side sleeves which are respectively arranged atthe two sides of the central sleeve are sheathed on the mandrel, clearance matching is preserved both between the mandrel and the central sleeve and between the mandrel and the side sleeves, one outer scraping belt is sheathed on each side sleeve by interference fit and the inner scraping belts are sheathed on the two ends of the central sleeve by the interference fit; a limiting chuck which is positioned at the inner side of the outer scraping belt and pivoted with the middle of the outer scraping belt suppresses the inner scraping belts at the two sides of the limiting chuck so as to limit the inner scraping belts; the limiting chuck which is positioned at the outer side of the inner scraping belt and pivoted with the middle of the inner scraping belt suppresses the outer scraping beltsat the two sides of the limiting chuck so as to limit the outer scraping belts; an annular groove which is concentric with a through-hole threaded by the side sleeve is arranged at the inner side of the outer scraping belt, and one annular groove which is concentric with the through-hole threaded by the central sleeve is arranged at the outer side of the inner scraping belt. The central plate link chain has long service life, high strength, convenient loading-unloading process, stable running and low limit of the characteristics of materials.

Description

Technical field [0001] The invention relates to a component structure of a transportation machine, in particular to a structure of a plate chain used in a chain bucket elevator. Background technique [0002] The chain bucket elevator adopts the plate chain running in a closed cycle as the conveying equipment. The chain bucket fixed on the plate chain is filled with materials to be transported. The chain bucket runs to the top of the plate chain circle and then turns over to throw the material out of the chain bucket. . [0003] The existing traditional NE plate chain adopts the structure type of sleeve roller chain, which is composed of two thin-walled sleeves inside and outside, that is, the middle sleeve and the roller sleeve. Such as figure 1 , figure 2 As shown: the outer chain plate 1' is sleeved on the mandrel 5' and is positioned on the steps at both ends of the mandrel 5' by the bolt and nut structure 6'. The mandrel 5' is sleeved with an intermediate sleeve 4', ...

AI Technical Summary

Problems solved by technology

NE plate chain chain speed is low (V≤0.7m / s), gravity unloading, that is, the chain bucket 8' turns over the apex and the material flows out with its own gravity, so that the fluid and viscous material cannot be unloaded
