摘　　要：用位移传感器测量出起重机车架相对于轨道的偏斜量,以此量作为控制信号,通过变频器调整驱动电动机的转速,而自动修正车架的偏斜,并加强车架的水平刚性,使起重机"啃道"现象得以基本消除。The deviating distance of crane frame from track is measured by displacement sensor and taken as the control signalBy adjusting the rotational speed of electromotor with frequency converter,the deviation of crane frame from track is automatically corrected and the horizontal rigidity of crane frame strengthenedWith these measures,the trackgnawing by crane in operation can be avoided

关 键 词：起重机 啃道 治理 变频调整
