ZL50型装载机在矿山使用中铲斗常出现:斗齿螺栓折断;斗齿螺栓孔和铲斗螺栓孔变形,甚至裂开;铲斗缘卷边、开裂等损伤。 螺栓折断、螺栓孔变形、裂开的原因是,装载机在对爆破后的原矿作业时,会遇到阻力大的大块矿石,铲斗斗齿受到左、右、前3个方向的力,随着作业的延续,螺栓、螺栓孔受到反复作用的剪切力,导致螺栓折断,螺栓孔变形 ZL50 loaders in the mining mines often appear: bucket teeth bolts broken; bucket tooth bolt hole and bucket bolt hole deformation, or even split; edge of the bucket edge curling, cracking and other damage. Bolt breakage, bolt hole deformation, split reason is that the loader in the blasting of ore operations, will encounter a large resistance large ore, bucket bucket teeth by left, right, the first three directions of force, With the continuation of the operation, the bolts and bolt holes are repeatedly subjected to shearing forces, causing the bolts to break and the bolt holes to deform
