SCRAPER RECLAIMER Russian patent published in 2022 - IPC B65G65/28 

FIELD: transport machine building.

SUBSTANCE: invention relates to handling machine building and can be used in conveyor lines when unloading warehouses of loose materials. Scraper reclaimer includes a bridge on portal structures equipped with a running gear in the form of two bogies made with possibility of movement along rails laid along the longitudinal axis of the warehouse, loading scraper conveyors fixed on portal structures, made in the form of arrows with scraper chains, equipped with lifting equipment, unloading chute. Portal structure on the side of the unloading chute is rigidly fixed on the support post of the corresponding bogie, and the opposite portal structure is pivotally fixed on the support post of the other bogie by a spherical support consisting of a sphere fixed in guides in the lower part of the portal structure and installed in a thrust bearing with a spherical insert fixed on the support post of the bogie. Each bogie includes a traverse made in the form of a longitudinally arranged rectangular beam, on which a support post is rigidly fixed, two lugs are fixed on the edges of the post, in which either balancers are hinged, containing two running wheels with drives and thrust rollers fixed with the possibility of covering the head of said rail from the sides, or intermediate balancers, in the lugs of which two said balancers with running wheels are fixed; or balancers containing one running wheel with a drive and thrust rollers on one side and an lug on the other side, in which the said balancer with two running wheels is hinged.

EFFECT: higher reliability of running gear elements and the portal structures attachment points to it, reduced wear intensity of under-reclaimer runways, prevention of deformations of their base, as well as exclusion of the possibility of running wheels derailing.
