摘 要
本設(shè)計(jì)為QD型帶式輸送機(jī)的設(shè)計(jì),以低制造成本、結(jié)構(gòu)簡便、安全可靠為設(shè)計(jì)宗旨,在采用傳統(tǒng)的QD型帶式輸送機(jī)的設(shè)計(jì)方法、設(shè)計(jì)數(shù)據(jù)的同時(shí)采用了部分先進(jìn)的新型帶式輸送機(jī)的計(jì)算方法及計(jì)算數(shù)據(jù)。
本設(shè)計(jì)在托輥組選型設(shè)計(jì)部分,通過對帶式輸送機(jī)托輥組間距的合理確定及優(yōu)化布置,大大減少了托輥組用量。承載段托輥組由原來的1000組減少到400組,回程段也相應(yīng)地由原來的500組減少到200組,極大地降低了制造成本、維護(hù)成本,簡化了結(jié)構(gòu),提高了運(yùn)行的可靠性。
拉緊裝置設(shè)計(jì)部分,通過分析研究各種拉緊裝置的優(yōu)缺點(diǎn)來設(shè)計(jì)拉緊裝置。把重錘車式拉緊和絞車?yán)o結(jié)合起來使用,在不提高成本的基礎(chǔ)上綜合了兩種拉緊方式的優(yōu)越性。
帶式輸送機(jī)驅(qū)動(dòng)裝置配置過高是一種資源浪費(fèi),而配置過低又會(huì)嚴(yán)重影響輸送機(jī)壽命,所以選擇合理的驅(qū)動(dòng)裝置、降低維修工作量和運(yùn)營成本是選擇驅(qū)動(dòng)裝置的關(guān)鍵。本設(shè)計(jì)綜合分析研究了幾種驅(qū)動(dòng)裝置的優(yōu)缺點(diǎn),合理選配了Y型電動(dòng)機(jī)+調(diào)速型液力偶合器+減速器型驅(qū)動(dòng)裝置。
了解和掌握帶式輸送機(jī)輸送帶跑偏原因及糾偏方法,對保證帶式輸送機(jī)的安全運(yùn)行是非常重要的。本設(shè)計(jì)調(diào)偏裝置設(shè)計(jì)部分就以上問題分析了輸送帶跑偏的原因及調(diào)偏原理并提出了解決跑偏的有效措施。
關(guān)鍵詞:帶式輸送機(jī);托輥間距;拉緊;驅(qū)動(dòng);調(diào)偏
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
