立式往复升降设计.doc

摘　要 立式往复升降机是机械行业，建筑行业中用于喷涂的一种机械设备。传统的喷涂工作通常是由手工操作完成的，通过人工的经验或者视觉来进行喷涂工作。这样的工作量大，并且精度很低，工作效率不高，喷涂往往不均匀，难以达到工作要求。随着科学技术的发展，自动化科学的发展，这种手工操作已经可以用机电产品来代替完成。这种手工操作不适合现代发展的需要。 本设计的任务是设计一台机电产品，来进行喷涂，以更好更快的完成喷涂工作。本设计采用链传动，传动比为1：1，链轮在垂直方向上，上下各置一个。在链轮中间连接一个移动小车，移动小车通过链带动，在立柱上滚动。喷涂喷枪就安装在小车上。通过链传动带动小车上下往复运动，从而实现垂直往复喷漆。链传动由交流变频电机驱动链轮以实现，往复运动的位移、速度、启动、停止采用PLC和变频器进行控制。本设备设有专门的控制面板。 关键词：垂直往复喷涂机；链传动；PLC控制 Abstract Vertical reciprocating elevator is a mechanical equipment used for spraying in mechanical industry and architecture industry.Usually, traditional work of spray is complete by handwork,and progress spray work through manual experience and vision. In this way, the quantity of work is great, precision and work efficiency are low, and something spraying is growl or not uniformity. So it is difficult to meet the demand of work. Along with the development of science and technology, automation science; such handwork does not suit the development of modernization and it can be substituted by mechanical-electrical equipment. The mission of this design is to designs a mechanical-electrical equipment to complete the spray work more fine and more rapidly. This equipment adopts chain drive, and the rate of the transmission is one to one. The chain wheel is fixed on the perpendicular direction, the top and bottom is each to place. In the middle of the chain, set a small car which is drive by the chain transmission and roll on the vertical pole. The spray guns install on the small car. Through the chain transmission drives the small car doing top and bottom moving. Just this vertical back and forth spray is complete. And the chain is drived by a direct current frequency conversion electromotor. The displacement, speed startup and halt of the back and forth moving, are controlled by PLC and transducer. And this facility mounts a special control panel. Key words Vertical reciprocating elevator；Chain transmission；PLC 目　录 TOC \o 1-2 \h \z \u HYPERLINK \l _Toc297295342 第1章　绪 论 PAGEREF _To
