Design of Telescopic Mobile Belt Conveyor

Abstract

This article refers to the general design of the belt conveyor, and analysis of some of the common characteristics of light conveyor,the design of an innovative multi - functional belt conveyor with three functions: telescopic, mobile and variable amplitude is designed. The scheme focuses on the analysis and discussion of the telescopic mechanism.

In this paper, the development situation, future development trend, design purpose, design direction and significance of the domestic and foreign transport aircraft are summarized. The core content analyzes the telescopic form and the transmission form of the telescopic conveyor. The design of this paper is based on the design of the QD80 Belt Conveyor, and it is reasonable to select a part of the available parts in the QD80 Conveyor. The most important telescopic scheme is to design the telescopic mechanism. The telescopic mechanism is the screw between the application screw In order to achieve the scalable design requirements of the conveyor, through the relevant calculation of the corresponding data of the telescopic mechanism for the belt conveyor in a variety of environments are carried out under the corresponding model of the simplified model, and the corresponding circumstances of the force Analysis, through the calculation of the results should ensure that in some extreme transport state of the overall body of the reliability and security. One part of the transmission mechanism is driven by the motor reduction gear, after deceleration and transmission to the nut screw mechanism to form.

In this paper, the design of the telescopic mechanism is designed in the same way as the movable and variable amplitude function, and the calculation of the corresponding data. Some of the parts involved can be obtained by purchasing and factory customization. The multi-purpose, multi-purpose innovation of the transport machine was envisaged.
