Lifting structure for building section bar storage

Abstract

The invention discloses a lifting structure for building section bar storage. The lifting structure comprises a cabinet body, two motors and two chain wheel sets including driving chain wheels and driven chain wheels, wherein a rotary shaft is composed of a main body located in a middle section and fixed sections at two ends, a hopper is fixed to the main body, a movable cavity with an oval crosssection is arranged in each fixed section, reduced sections are arranged at two ends of the main body in an outward extending mode, two limiting blocks incremental in the circumference directions of the reduced sections in thickness are symmetrically arranged on the outer walls of the reduced sections along their axes, the vertical distances from the maximum ends of the limiting blocks to the outer walls of the reduced sections is a, the a are greater than the semi-minor axes of cross sections of the movable cavities and meanwhile are smaller than the semi-major axes of cross sections of the movable cavities. When the maximum ends of the limiting blocks slide through the tail ends of the semi-major axes of cross sections of the movable cavities, the maximum ends of the limiting blocks arein contact with the walls of the movable cavities so as to prevent continuous rotation of the limiting blocks, the rotary shaft and the hopper, and the phenomenon is avoided that the shaking range ofthe hopper continuous to increase and accordingly the hopper bumps against a hopper adjacent or close to it.

Description

technical field [0001] The invention relates to the field of building construction, in particular to a lifting structure for storing building profiles. Background technique [0002] On the construction site, the cost of some components is relatively high, and they need to be managed intensively and finely to control the cost of raw materials during the construction process. However, the existing storage of valuable accessories basically adopts the traditional storage management method-ordinary open shelf storage. The main disadvantages of this management method are: the height and area of ​​the existing house cannot be fully utilized; it is necessary to frequently pick up the items placed on the upper shelf, use ladders to climb up and down, and carry them over long distances. The labor intensity of the staff is high and the efficiency is low. The items on the open shelves are polluted by dust and are not suitable for the storage of some precision spare parts; it is impossi...

However, the existing storage of valuable accessories basically adopts the traditional storage management method - common open shelf storage

The main disadvantages of this management method are: the height and area of ​​the existing house cannot be fully utilized; it is necessary to frequently pick up the items placed on the upper shelf, use ladders to climb up and down, and carry them over long distances. The labor intensity of the staff is high and the efficiency is low. The items on the open shelves are polluted by dust and are not suitable for the storage of some precision spare parts; it is impossible to restrict irrelevant personnel from accessing items on the shelves, which makes the management chaotic; it is difficult to adopt the first-in first-out management method, inventory, clear The warehouse is difficult; the warehouse looks messy, untidy and beautiful, which hinders the appearance of the warehouse
