Vertical transportation device for materials in elevator shaft

Abstract

The utility model discloses a vertical transportation device for materials in an elevator shaft, which relates to the technical field of constructional engineering and comprises elevator shaft walls, sliding rails are mounted on adjacent sides of the elevator shaft walls, a plurality of clamping grooves are formed in the sliding rails, a transportation frame is arranged between the elevator shaft walls, the transportation frame comprises a first tray and a second tray, and the first tray and the second tray are arranged in parallel. The lower side of the first tray is fixedly connected with two groups of fixing frames, a spring plate is fixedly connected between the fixing frames, the lower side of the spring plate is provided with a limiting rod, and the limiting rod is hinged to the fixing frames; when a spring plate is bent, pressure is applied to a limiting rod through a threaded rod, so that one end of the limiting rod moves downwards, the limiting rod moves towards the direction of a sliding rail until one end of the limiting rod is clamped into a clamping groove, the downward moving conveying frame is clamped, and the position of the conveying frame on the sliding rail is fixed; and the transportation frame cannot fall to the bottom of the elevator shaft, so that personal safety and materials are protected.
