1.制作原因履带式挖掘机在我港口装卸作业中使用频率高、作业负荷大、作业工况较差,其链轨磨损比较严重。挖掘机链轨磨损严重后,在作业和行走过程中就会发生链轨脱出故障,造成挖掘机无法继续作业和行走。链轨磨损部位主要是轴套及销轴,因此需要进行更换。然而磨损严重的轴套可造成轴销无法拆卸,没有专用工具拆卸比较困难,一般需要工人用乙炔火焰烘烤,甚至割断磨损的链轨节,这样容易造成链轨节退火、材质发生变化,导致使用性能下降。为了使链轨销轴拆装简单方便、安全
1. Production reasons Crawler excavator in my port loading and unloading operations in the use of high frequency, large operating load, poor working conditions, the chain track wear more serious. Excavator chain track after serious wear and tear, in the process of operation and walking will occur chain link failure, resulting in excavators can not continue their operations and walking. The wear parts of the chain track are mainly bushings and pins, so they need to be replaced. However, serious wear sleeve can cause the shaft pin can not be disassembled, there is no special tool to disassemble more difficult, generally require workers with acetylene flame baking, or even cut off the worn chain link, so easy to cause the chain link annealing, material changes, resulting in Degraded performance. In order to make it easy and safe to dismount the chain link pin
