Abstract
This design is the design of the belt conveyer of QD model, concentrate on low manufacturing costs, simple structure and reliable design which have adopted enumerated data and the design method of advanced belt conveyers while adopting design data and the design method of the belt conveyer of QD model of tradition.
Design in the part of bearing roller selecting , greatly reduced the quantity of bearing roller groups by the reasonably determine and optimization arrange of across block of bearing roller groups. The bearing groups from 1000 groups of original decreasing go to 400 groups, the section of return trip also goes to 200 groups correspondingly by 500 groups of original decreasing. In pull installation design part, select pull installation design by analysis advantages and shortcomings of various pull installation. Combine hammer vehicle pull installation to winch pull without increasing cost, as a result, synthesized the superities of both two.
It’s a kind of resource waste to use high disposition of actuating device for belt conveyer, but low disposition would serious influence conveyer life, so select actuating device reasonably is very important. At last choose the motor of Y model + hydraulic coincidence ware of speed adjustment + gear reducer as actuating devices. Belt conveyer is a main transport equipment, analyses the reasons of conveyer belt off tracking, puts forward improving measures and precautions to ensure the safety operation of belt conveyer.
KeyWords: belt conveyer, span, pull, actuating device, off tracking
