Description

多级护密封伸缩轴套往复冲击部 技术领域
本发明涉及采掘机械领域,具体涉及一种多级护密封伸缩轴套往复冲击部。
背景技术
因往复冲击采掘机的落料方式为往复敲击落料,故动能的利用率高,粉尘少,因此往复冲击落料方式倍受欢迎,但由于往复冲击箱体与导向冲击件之间采用单道密封,密封效果差,密封处因往复冲击的反作用力及物料等外力冲击砸撞频繁导致导向冲击件密封伸缩面损坏、箱体密封件等损坏,造成往复冲击箱体内润滑降温介质泄漏,粉尘、泥水、物料等进入往复冲击箱体内,致使往复冲击箱体内动力系统部件损坏,无法长时间连续工作,在采掘矿物、掘进巷道的工作现场维修更换往复冲击箱体内轴承、曲轴、连杆、导向冲击件、导向件等用工用时量大,甚至于难以完成维修工作,为了对导向冲击件、箱体密封件等加以保护,曾在方形往复冲击箱体周围加了防护板,防护板抱在往复冲击箱体外,因防护板比往复冲击箱体还要高还要宽,防护板随导向冲击件往复运动增加了动力消耗,增加了往复冲击头的总体重量,大大增加了对防护板与往复冲击箱体之间密封难度,防护结构总体造价高制造难度大,又因两导向冲击件左右设置在同一曲轴上前后交错往复冲击,前后交错运动的防护板之间必有间隙,物料、粉尘、泥水等从防护板多处间隙进入防护板与往复冲击箱体之间,长时间大量堆积后物料板结在防护板与往复冲击箱体之间形成垫层,板结垫层不断增厚导致阻挡往复冲击头向后回缩致使往复冲头脱落,因此造成了往复冲击采掘机总体结构原理合理,但配套细节结构及部件不能满足往复冲击采掘机长期有效工作的要求,甚至给使用方带来巨大的停产损失,导致往复冲击采掘机至今不能为矿业采掘做出节能环保的贡献,为了解决上述问题,本发明提出了一种多级护密封伸缩轴套往复冲击部。
