中文摘要：

作为一种新兴运输方式,索道运输正在工程施工中得到越来越多的应用,在一些交通不便或环境恶劣的山区更是如此。当前工程索道普遍存在着自动化程度不高、可靠性不足以及作业效率低下等问题。因此,索道的自动化改造是未来索道发展的必然趋势之一。工程索道通常在强晃动,大偏差的工况下工作,行走小车螺栓的松紧便成为制约索道自动化运行的关键问题。利用三爪伸缩卡盘,通过单电机多传递线路,设计一种具有在强晃动工况下的宽域捕捉能力且扭矩可调的自动化螺栓松紧装置可有效地解决以上问题。实际应用表明,该装置完全能够在强晃动、大偏差的工况下工作,经济高效且安全可靠。

英文摘要：

As a new way of trausportation, cableway transportation is more and more used in the engineering construction, especially in some inaccessible or harsh mountain region, Currently, there are a lot of widespread problems On engineering ropeway, for example, the level of automation is not high, the reliability is not enough and the e Ortciency is low. Therefore, the automation transformation of c~bleway is one of the cableway development trends in the future. Because the engineering ropeway usually works in the conditions of strong shaking or the big deviation, the walk-car＇s hanging or off cable has become the key problem of the engineering ropeway＇s automatic operation, Designs a new torque adjustable automatically loosen and tighten bolt device with the capability of wide domain＇s capturing under the strong shaking condition through single motor transmission lines by the three jaw chuck. Tests show that the device can completely adapt to working condition of strong shaking or the big deviation of the engineering ropeway and own the high economic efficiency and safe reliability.
