矿山生产用的挖掘机部件磨损很快,日常维护和检修工作是延长挖掘机使用寿命的重要环节之一。挖掘机铲杆由于频繁的受到冲击、振动和各方向的负荷,经常产生铲杆侧向弯曲和垂直弯曲以及扭曲等变形。如不及时处理,变形逐渐增大,最后迫使停产检修。这种变形的修复可以在日常维修和检修工作中进行,这样才能保证挖掘机正常工作。过去在挖掘机
Excavator parts for mine production wear quickly, and routine maintenance and overhaul work is an important part of extending the service life of excavators. Excavator shovels are often subjected to shock, vibration and load in all directions, often resulting in shovels lateral bending and vertical bending and distortion and other deformation. If not handled in time, deformation gradually increased, and finally forced to stop production and overhaul. This deformation of the repair can be carried out in the routine maintenance and repair work, so as to ensure the excavator to work properly. Past excavator
