能不能介绍一下呀？

改用png文件15kb

谢谢CHENDZ的提醒，下次贴图时注意。该机器是一个升降平台，图示的是一部份，是悬挂在龙门架上的一部份，注意图示上部的两根工字钢，就是安装在龙门架上的，该平台有升降、走行（一个方向）个作用，其中升降的传动装置要求装在平台上，不能装在上部。见另一视图。<img src="attachments/dvbbs/2003618852625850.gif" border="0" onload="if(this.width>screen.width*0.7) {this.resized=true; this.width=screen.width*0.7; this.alt=\'Click here to open new window\nCTRL+Mouse wheel to zoom in/out\';}" onmouseover="if(this.width>screen.width*0.7) {this.resized=true; this.width=screen.width*0.7; this.style.cursor=\'hand\'; this.alt=\'Click here to open new window\nCTRL+Mouse wheel to zoom in/out\';}" onclick="if(!this.resized) {return true;} else {window.open(\'attachments/dvbbs/2003618852625850.gif\');}" onmousewheel="return imgzoom(this);" alt="" />

我想知，可是看不清你做的是什么？

chendz

图样确实太小，
不过挺有创意。

好像是工字钢上行走机构，相当于“小车”，（龙门架相当于“大车”）
四螺杆机械同步升降，相当于“起升”机构，只是起升动力在平台（相当于“吊钩”）上。

不知对否？

能否介绍一下，采取了那些较新技术：
电缆怎样悬垂？
同步怎样控制？
如何防止平台扭摆？

楼主不讨论希望讨论的问题啦？

wearepeopl

看样子6楼是个经验丰富的机械工程师，所说一点不错，提出的三个问题：电缆怎样悬垂？
同步怎样控制？如何防止平台扭摆？也正是我在设计中考虑的三个主要问题。既然楼主不希望讨论这样的问题，那我就不再讨论了，不过这里边没什么新技术，有的只是许多的、繁琐的零件绘制。

到底谁是楼主呀？8楼不是吗？看8楼 帖子好像别人是楼主。

以下是引用wearepeopl在2003-6-21 15:36:07的发言：
不过这里边没什么新技术，有的只是许多的、繁琐的零件绘制。

往往平常之处见真功夫，重在积累，
有多少实用设计不见得用了多少高新技术，
最简单解决问题的方案就是最好的。

关于电缆悬垂：可否考虑用绕线轮，安全美观。特别是提升高度较大时。
关于同步控制：通常实用场合，利用珩架式结构的刚性和弹性自同步足矣，电气同步未必更可靠。
关于平台扭摆：加大平台的宽度满足需要，必要时可加导向柱。

电缆垂悬采用滑轮；
升降同步采用机械刚性同步；
防扭摆采用丝杆外加套刚性伸缩套筒。
平台尺寸为1400*4100，平台荷载按2T集中载荷计算。
选定传动系统各参数：传动锥齿模数、齿数；驱动电机功率等等。<img src="attachments/dvbbs/2003622736248111.gif" border="0" onload="if(this.width>screen.width*0.7) {this.resized=true; this.width=screen.width*0.7; this.alt=\'Click here to open new window\nCTRL+Mouse wheel to zoom in/out\';}" onmouseover="if(this.width>screen.width*0.7) {this.resized=true; this.width=screen.width*0.7; this.style.cursor=\'hand\'; this.alt=\'Click here to open new window\nCTRL+Mouse wheel to zoom in/out\';}" onclick="if(!this.resized) {return true;} else {window.open(\'attachments/dvbbs/2003622736248111.gif\');}" onmousewheel="return imgzoom(this);" alt="" /><img src="attachments/dvbbs/20036227361424117.gif" border="0" onload="if(this.width>screen.width*0.7) {this.resized=true; this.width=screen.width*0.7; this.alt=\'Click here to open new window\nCTRL+Mouse wheel to zoom in/out\';}" onmouseover="if(this.width>screen.width*0.7) {this.resized=true; this.width=screen.width*0.7; this.style.cursor=\'hand\'; this.alt=\'Click here to open new window\nCTRL+Mouse wheel to zoom in/out\';}" onclick="if(!this.resized) {return true;} else {window.open(\'attachments/dvbbs/20036227361424117.gif\');}" onmousewheel="return imgzoom(this);" alt="" /><img src="attachments/dvbbs/20036227364323267.gif" border="0" onload="if(this.width>screen.width*0.7) {this.resized=true; this.width=screen.width*0.7; this.alt=\'Click here to open new window\nCTRL+Mouse wheel to zoom in/out\';}" onmouseover="if(this.width>screen.width*0.7) {this.resized=true; this.width=screen.width*0.7; this.style.cursor=\'hand\'; this.alt=\'Click here to open new window\nCTRL+Mouse wheel to zoom in/out\';}" onclick="if(!this.resized) {return true;} else {window.open(\'attachments/dvbbs/20036227364323267.gif\');}" onmousewheel="return imgzoom(this);" alt="" /><img src="attachments/dvbbs/20036227365293370.gif" border="0" onload="if(this.width>screen.width*0.7) {this.resized=true; this.width=screen.width*0.7; this.alt=\'Click here to open new window\nCTRL+Mouse wheel to zoom in/out\';}" onmouseover="if(this.width>screen.width*0.7) {this.resized=true; this.width=screen.width*0.7; this.style.cursor=\'hand\'; this.alt=\'Click here to open new window\nCTRL+Mouse wheel to zoom in/out\';}" onclick="if(!this.resized) {return true;} else {window.open(\'attachments/dvbbs/20036227365293370.gif\');}" onmousewheel="return imgzoom(this);" alt="" />

不是吧

确实是小车

什么都没有呀

能不能把把原文件上传，

高手

因公司有保密制度，源文件不好上传，不好意思啦！
