钢卷运输车

摘要

钢卷运输车是广泛用于轧钢生产线上的一种重要的轧钢辅助设备，其设计特点和工作性能的好坏直接影响到整个轧钢生产线的生产效率。它是将卷取机上的钢卷运输到打捆机的重要运输设备，给轧钢生产带来了极大的方便。本设计主要是对钢卷运输车的行走传动机构和升降机构进行设计和改造。本次设计研究的主要内容包括总体方案设计的选择、行走机构、升降机构的设计、主要零部件的设计与校核等。在本设计中钢卷运输车的行走机构的驱动方式的选择了电机驱动，由于传动比较大，故小车的传动机构选择了二级齿轮蜗轮蜗杆减速器。该减速器有两个输出端通过联轴器联接驱动车轮轴使车轮转动。钢卷运输车的升降动作由液压缸驱动完成。现如今随着我国钢铁行业的迅速发展，轧钢生产相关的设备也向着高效、简单、节能化发展。钢卷运输车在轧钢实现自动化生产方面起到了很大的作用，所以对于钢卷运输车的设计，既要其安全可靠，也要易于检修和维护，适合不同的生产要求同时也要最大程度的降低成本。国外该技术已比较发达，我国在引进国外技术的同时也要根据实际需要不断的创新。促进我国轧钢生产实现更加快速的发展。

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
