Screw elevator

Abstract

The invention discloses a screw elevator. The screw elevator comprises a machine frame and a screw conveying line, wherein the screw conveying line is arranged in the machine frame and ascends in a screw mode in the axial direction of the machine frame; the screw conveying line comprises motors, rollers, a controller and screw side plates, wherein the controller is fixed to the machine frame or the screw side plates and is electrically connected to the motors, the motors are connected to the rollers in a driving mode, the rollers are connected through a driving belt, and the two ends of each roller are fixed to the screw side plates; the screw conveying line is divided into an upper port conveying section, a screw conveying section and a lower port conveying section, wherein the upper port conveying section, the screw conveying section and the lower port conveying section are sequentially connected, and the screw conveying section adopts the multi-section design and is formed by splicing a plurality of single screw conveying bodies. According to the screw elevator, the sectional design is adopted so that the movement of material can be controlled, and individual control over the motors is adopted so that the material can be accumulated.

Description

technical field [0001] The invention relates to the technical field of elevators, in particular to a spiral elevator used for material transmission. Background technique [0002] The hoist is a large-scale mechanical equipment that is transported by changing the potential energy. It is used in various fields, and the main applications in the field of logistics and storage include non-powered screw conveyors and plate chain screw hoists. [0003] The structure of the unpowered screw conveyor is limited to one-way conveying, and the conveyed material slides from a high place to a low place. The disadvantages of this unpowered screw conveyor: it can only transport empty or light-weight boxes, and the pause control cannot be performed during the operation, and the movement speed of the material is uncontrollable. In addition, the height of the overall conveying line should not be too high . [0004] The plate chain screw elevator drives the plate to lift through the mechanical...

Problems solved by technology

The disadvantages of this unpowered screw conveyor: it can only transport empty or light-weight boxes, and the pause control cannot be performed during the operation, and the movement speed of the material is uncontrollable. In addition, the height of the overall conveying line should not be too high

[0004] The plate chain screw elevator drives the plate to lift through the mechanical chain, so that the material is transported from the ground to a certain height in the vertical space. It saves labor and space when used, and is widely used in the field of conveyors. However, this plate The defects of the chain screw elevator: the plate chain equipment is expensive, the manufacturing cost is high, the equipment manufacturing precision is high, and the maintenance is troublesome; in addition, the plate chain screw hoist adopts an integrated design, and once an emergency occurs, the entire conveying Line stops and paralysis greatly reduces work efficiency
