摘　　要：通过数学建模、推导链长偏差与摆杆倾斜角度的解析关系以及几何作图和现场试验,确认导致摆杆接车失败的首要原因是左右链条从出口到入口的长度偏差,此偏差导致摆杆底部支撑杆在接车位偏斜。偏斜量超过橇体支撑碗宽度一半时,承载杆将不能插入橇体支撑碗内导致上件失败。提出了快速调整链长偏差、避免接车故障的多种技术措施及对链条磨损进行预测性维护的技术方案:通过传感器监测配重箱高度差和左右链条在出口和入口的同步性、推算链条长度偏差和阈值比较。Through mathematical modeling and deducing the analytical relationship between the chain length deviation and the tilt angle of the pendulum during operation,as well as geometric drawing and field test,it is confirmed that the main reason leading to the failure of picking up a car is the length deviation of the left and right chain from the exit to the entrance,which leads to the deflection of the support rods at the bottom of the pendulum at loading position.When the deviation exceeds half of the width of the skid carrying bowl,the bearing rod will not be inserted into the bowls,resulting in failure of a car picking-up.A variety of technical measures to quickly adjust the chain length deviation,avoid the loading failure and the technical scheme for predictive maintenance of chain wear are put forward:sensors are used to monitor the height difference of the weight boxes and the synchronization of the left and right chain at the exit and entrance,the chain length deviation is calculated and compared with the threshold value in real time.
