Sealing device for lifting drum of mining excavator
The invention relates to the technical field of sealing, and provides a sealing device for a lifting drum of a mining excavator, which comprises a sealing bracket arranged on a speed reduction box body of a lifting machine, and a penetrating hole is formed in the middle of the sealing bracket; the multiple mounting grooves are formed in the sealing support at intervals along the axis of the sealing support, and the mounting grooves communicate with the penetrating hole; the sealing ring is arranged in the mounting groove and is positioned in the mounting groove close to one side of the speed reduction box body of the elevator; the felt strip is arranged in the mounting groove and is positioned in the mounting groove on one side far away from the speed reduction box body of the elevator; the first elastic piece is arranged in the mounting groove, one end of the first elastic piece abuts against the sealing ring or the felt strip, the other end of the first elastic piece abuts against the mounting groove, and the first elastic piece is used for providing force for the sealing ring or the felt strip to be close to the elevator drum shaft. By means of the technical scheme, the problem that in the prior art, a mining excavator lifting drum sealing ring is poor in sealing effect is solved.
本发明涉及密封技术领域，提出了一种用于矿用挖掘机提升卷筒密封装置，包括密封支架设置在提升机减速箱体上，且密封支架中间具有穿过孔；安装槽具有若干个，沿密封支架轴线间隔设置在密封支架上，安装槽与穿过孔连通；密封圈设置在安装槽内，密封圈位于靠近提升机减速箱体一侧的安装槽内；毛毡条设置在安装槽内，毛毡条位于远离提升机减速箱体一侧的安装槽内；第一弹性件设置在安装槽内，第一弹性件一端与密封圈或毛毡条抵接，第一弹性件另一端与安装槽抵接，第一弹性件用于提供密封圈或毛毡条靠近提升机卷筒轴的力。通过上述技术方案，解决了现有技术中矿用挖掘机提升卷筒密封圈密封效果不好的问题。
