新型悬挂起重机防倾翻装置的设计

Design of new underslung crane anti-tipping device

介绍了新型防倾翻装置设计,即采用反滚轮在轨道下平面上运行的形式,不但能够实现防倾翻,而且解决了起重机在大车负轮压时正常运行的问题,论述了该装置的原理、结构及稳定性的验算方法,指出了设计新型防倾翻装置的注意点,具有实用价值,供同行业参考。

The paper introduces design of new anti-tipping devi ce,which uses the form that the reaction wheel runs on the lower surface of the r ail,not only achieving anti-tipping,but also solving the issue concerning nor mal operation of crane in case of negative wheel pressure,discusses the princip les,structure and stability checking method of the device,and offers the ideas for the design of new anti-tipping device.It has practical value for industry reference.
