| 摘 要： | 为了消除电梯用钢丝绳在使用中的结构伸长,将成品钢丝绳在捻制后施加一定的张力.预张拉管式捻股机能使钢丝绳在通过第1牵引轮后,再经过1组测力装置和第2牵引轮,调节第2牵引轮的速度给钢丝绳一定的张力,即可实现钢丝绳的预张拉.分析2组牵引轮之间钢丝绳恒张力的电气控制原理及张力过载保护措施,给出张力自动控制的框图和张力检测的示意...

| Abstract: | To eliminate structure elongation of wire rope in use for lift,finished wire rope is added certain tension after spinning.Pretension tubular strander can realize pretension of wire rope through the following process: after wire rope passed the first traction wheel,then passed through a set of force testing system and the second traction wheel,to adjust the speed of the second traction wheel to give certain tension on wire rope.The electric control principle and tension overload protection measure of wire ro... |
