VERTICAL BELT CONVEYOR

摘要

FIELD: transport; conveyers. ^ SUBSTANCE: square flat slabs (17, 18) are located one under the other in the upper part of the conveyor between load-carrying (8) and return (9) runs of the first round with gaps relative to them. The width of the slabs equals to the width of the belt, the height is more than the step of shelves (12) position. The side edges on the top and underneath of the slabs are gimbal-fixed with ends of the slope and parallel located to each other double-arm levers (23). The levers are gimbal-mounted on the brackets of the support frame creating a parallel crank mechanism possible to turn in the vertical cavity together with the slabs and support frame. The bottom double-arm levers are equipped with balance weights (35) installed on the opposite ends of the levers. The upper levers of each slab are located with the possibility to rest against rods located below them. The rods are cantilever-fixed on the armature of electromagnets (39) with the possibility of moving rods in horizontal cavity. The electromagnets are electrically connected with electromotor of belt drive roll of the second round. In the initial position the levers of the upper slab are sloped down relative to the horizon and the levers of the bottom slab are sloped up. ^ EFFECT: provision the possibility oa capture and fixation of the load-carrying and return runs of the first round of belt at break off. ^ 3 dwg
