Abstract
The utility model discloses a furnace door lifting device for a quenching furnace, relating to the technical field of thermal treatment furnaces. The furnace door lifting device comprises a furnace, a furnace door and a frame arranged on the top of the furnace, wherein the frame is provided with a rolling shaft; cable wheels and a chain wheel are fixedly arranged on the rolling shaft; a motor is fixedly arranged on the top of the furnace; the left side of the motor is provided with a speed reducer; the speed reducer is connected with the chain wheel through a chain; limiting rollers and hoisting buckles are welded on both sides of the furnace door; the hoisting buckles are positioned above the limiting rollers. The furnace door lifting device has the advantages that the limiting rollers are welded on both sides of the furnace door, and friction between the furnace door and the furnace is reduced in the presence of a limiting gear, so that shake of the furnace door is reduced, and the service life of the furnace door is prolonged.
Description
Technical field
The utility model relates to heat treatment furnace technical field, relates in particular to a kind of quenching furnance furnace door lifting device.
Background technology
Steel ball is important base parts and components, and the lifting in the national economic development of especially accurate industrial ball acts on greatly under some special conditionss, usually needs the steel ball of special substance, completes the lower function that reaches of requiring of varying environment.Conventionally, after steel ball casting completes, need to quench, before steel ball quenching, need to heat-treat, heat-treat and just need stove.
In prior art, the Chinese utility model patent application that publication number is CN202915715U discloses a kind of furnace door lifting device, comprises stove and fire door; Also comprise be arranged on stove top frame, be arranged on drive unit, the follow-up pulley being connected with the output driving wheel of drive unit by driving chain in frame, be connected with follow-up pulley and rotate the driven shaft that is arranged in frame, be arranged on driven shaft
At least one sprocket wheel and one end are fixed on the other end on sprocket wheel and are fixed on the chain on fire door.It has mainly solved the problem of fire door slow start.
