鋼卷運(yùn)輸車

 摘要

鋼卷運(yùn)輸車是廣泛用于軋鋼生產(chǎn)線上的一種重要的軋鋼輔助設(shè)備，其設(shè)計特點(diǎn)和工作性能的好壞直接影響到整個軋鋼生產(chǎn)線的生產(chǎn)效率。它是將卷取機(jī)上的鋼卷運(yùn)輸?shù)酱蚶C(jī)的重要運(yùn)輸設(shè)備，給軋鋼生產(chǎn)帶來了極大的方便。本設(shè)計主要是對鋼卷運(yùn)輸車的行走傳動機(jī)構(gòu)和升降機(jī)構(gòu)進(jìn)行設(shè)計和改造。本次設(shè)計研究的主要內(nèi)容包括總體方案設(shè)計的選擇、行走機(jī)構(gòu)、升降機(jī)構(gòu)的設(shè)計、主要零部件的設(shè)計與校核等。在本設(shè)計中鋼卷運(yùn)輸車的行走機(jī)構(gòu)的驅(qū)動方式的選擇了電機(jī)驅(qū)動，由于傳動比較大，故小車的傳動機(jī)構(gòu)選擇了二級齒輪蝸輪蝸桿減速器。該減速器有兩個輸出端通過聯(lián)軸器聯(lián)接驅(qū)動車輪軸使車輪轉(zhuǎn)動。鋼卷運(yùn)輸車的升降動作由液壓缸驅(qū)動完成?，F(xiàn)如今隨著我國鋼鐵行業(yè)的迅速發(fā)展，軋鋼生產(chǎn)相關(guān)的設(shè)備也向著高效、簡單、節(jié)能化發(fā)展。鋼卷運(yùn)輸車在軋鋼實(shí)現(xiàn)自動化生產(chǎn)方面起到了很大的作用，所以對于鋼卷運(yùn)輸車的設(shè)計，既要其安全可靠，也要易于檢修和維護(hù)，適合不同的生產(chǎn)要求同時也要最大程度的降低成本。國外該技術(shù)已比較發(fā)達(dá)，我國在引進(jìn)國外技術(shù)的同時也要根據(jù)實(shí)際需要不斷的創(chuàng)新。促進(jìn)我國軋鋼生產(chǎn)實(shí)現(xiàn)更加快速的發(fā)展。

The Transport Vehicle Of Rolling Steel

Abstract

  The transport vehicle of rolling steel is an important auxiliary equipment which is widely used in rolling mill production line, its design features and work performance has a direct impact on the productivity of the entire rolling line. It is an important transportation equipment which transports steel roll from recoiling machine to bander, which make it convenient to the production of steel rolling. This design is mainly to design and remould the walking and driving mechanism and lifting mechanism of the transport vehicle of rolling steel. The main content of this design research includes the choice of the overall plan of design, traveling mechanism, the design of lifting mechanism and the design of main components’ design and checking and so on. In this design，the drive mode of traveling mechanism  of transport vehicle of rolling steel is by motor machine. Because of the tachometer drive ratio is big, I choose two stage gear worm reducer for the small one. The reducer has two output ends which connect the wheels by coupler to make the wheels run. The movement of lifting mechanism is driven by the hydraulic cylinder to complete. Nowadays , with the rapid development of China's iron and steel industry, the related equipment of steel rolling production has efficient, simple, and energy saving development. The transport vehicle has played a big role in achieving automation production , so the design must be safe and reliable, easy to repair and preserve, suitable for different production requirements and also to reduce the cost of the big extent. The technology has been developed in other countries, so we should bring in the foreign technology and also innovate according to our actual need. To promote the steel rolling production for China to achieve more rapid development. 

KEY WORDS: rolling steel, transport, lifting mechanism, cold rolling
