FIELD: materials handling equipment; elevators. ^ SUBSTANCE: proposed vertical elevator for lump loads has flexible pull-and-carry loop consisting of two endless laminated chains closed in vertical plane on drive and tension sprockets. Carrying members for load to be transported are secured with equal pitch on chains. Elevator has housing consisting of front, rear and side walls, and charge and discharge branch pipe. Carrying members are made in form of shelves cantilever mounted at angle to chains. Each shelf has edge bent square to plane of chains. Shelves are furnished with stiffening ribs from non-working side of shaft. Chains with shelves secured on carrying run of conveyor are arranged with minimum clearances and possibility of interaction with inner vertical wall installed inside housing. Said wall is secured by ends on side walls of elevator housing and is provided with curvilinear section in zone of drive sprocket. Inner vertical wall can be coated with antifriction and wear-resistant material. ^ EFFECT: increased capacity of elevator, reduced overall dimensions of elevator housing, possibility of transportation of large-size lump loads at reliable discharge in zone of drive sprocket. ^ 4 dwg |
