The invention relates to the field of heat treatment equipment, in particular to a lifting device for the quenching process of rail wheels, which comprises a base, a lifting cylinder, a connecting rod, a waterproof mechanism and a guide mechanism, the lifting cylinder, the waterproof mechanism and the guide mechanism are respectively fixed on the base, and the lifting cylinder is used for providing lifting driving force; the waterproof mechanism comprises a waterproof lower cover and a waterproof upper cover, the lower portion of the waterproof lower cover is fixed to the base, the upper portion of the waterproof lower cover is provided with a step, the step comprises a waterproof lower cover vertical plate and a waterproof lower cover transverse plate, the waterproof lower cover vertical plate can stretch into the waterproof upper cover, and an opening of the waterproof upper cover faces downwards. The waterproof upper cover is connected with a piston rod of the lifting air cylinder through a connecting rod and moves up and down along with the piston rod, and the waterproof upper cover and the waterproof lower cover vertical plate coincide in the height direction when the rail wheel is cooled by spraying water. Furthermore, an included angle is formed between the waterproof lower cover transverse plate and the horizontal plane. By arranging the waterproof mechanism, the problem that the cylinder is damaged due to the fact that metal oxide skin enters the cylinder along with cooling liquid is solved; by arranging the guide mechanism, stable lifting of the workpiece is guaranteed.

    本发明涉及热处理设备领域,具体是一种用于轨道车轮淬火冷却过程的升降装置,包括底座、升降气缸、连接杆、防水机构和导向机构,升降气缸、防水机构和导向机构分别固定在底座上,升降气缸用于提供升降驱动力,连接杆用于连接升降气缸和防水机构,防水机构包括防水下罩和防水上罩,防水下罩下部固定于底座,上部设有台阶,台阶包括防水下罩立板和防水下罩横板,防水下罩立板能够伸入防水上罩内,防水上罩开口朝下,通过连接杆与升降气缸的活塞杆连接,跟随活塞杆上下运动,当轨道车轮被喷水冷却时,防水上罩和防水下罩立板在高度方向重合。进一步地,防水下罩横板与水平面有夹角。本发明通过设置防水机构,解决了金属氧化皮随冷却液进入气缸而造成气缸损坏的问题;通过设置导向机构,保证工件升降平稳。
