Description
Technical field
The utility model is related to a kind of tools for replacing heat treatment furnace bottom roller, belong to metallurgy industry heat-treatment furnace equipment skill
Art field.
Background technology
In metallurgy industry heat treatment production process, roller hearth heat-treated furnace is current more common equipment.Hearth roll
The phenomenon that usually will appear bulge or fracture in use, it is the frequent of heat-treatment furnace maintenance to hearth roll replace
Property project.It replaces hearth roll and coordinates roll change buggy usually using jack, roll change buggy is erected on two adjacent hearth rolls
Hearth roll is replaced.But can not be used in the neck region roll change buggy close to fire door, hearth roll adjacent rollers are continuous
When fracture, roll change buggy can not be placed.More the changing jobs of hearth roll becomes difficult heavy.
Utility model content
The utility model aim is to provide a kind of tool for replacing heat treatment furnace bottom roller, can be to the neck close to fire door
The hearth roll when hearth roll at place and other position roll change buggies can not use is replaced, and is solved present in background technology
Problem.
The technical solution of the utility model is：
A kind of tool for replacing heat treatment furnace bottom roller, including counterweight roller, thick walled steel tube, end one, end two and keyway,
End one and end two are separately fixed at the both ends of thick walled steel tube, are all provided on the end one and end two there are one keyway, are matched
One end of weight roller is fixed in the keyway of end one.
Fastening screw there are one being all provided on the keyway of the end one and end two.
Keyway on the end one and end two is matched with the roll neck of counterweight roller and hearth roll respectively.
Keyway on the end one and end two is U-shaped structure.
The end one and end two and the integrally welded structure of thick walled steel tube.
Using the utility model, at the neck of fire door hearth roll and other position roll change buggies can not use
When hearth roll when being replaced, it would be desirable to the roll neck of the hearth roll of replacement crosses fastening screw with end two-way and is fixed together,
The replacement of hearth roll can be easily completed by the cooperation of suspender again.
The utility model has the beneficial effects that：Can to close to fire door neck at hearth roll and other position roll changes
Hearth roll when trolley can not use is replaced, simple in structure, easy to use, of low cost, shortens the maintenance work period,
Also significantly reduce the labor intensity of maintenance personal.
Description of the drawings
FIG. 1 is a schematic structural view of the utility model；
Fig. 2 is the utility model use state diagram；
In figure：Counterweight roller 1, thick walled steel tube 2, hearth roll 3 to be replaced, passive end bearing block 4, Partner roller neck lining 5, stove
Body 6, end 1, end 28, fastening screw 9, keyway 10.
Specific implementation mode
Below in conjunction with attached drawing, by example, the utility model is described in further detail.
With reference to attached drawing 1, a kind of tool for replacing heat treatment furnace bottom roller, including counterweight roller 1, thick walled steel tube 2, end 1,
End 28 and keyway, end 1 and end 28 are separately fixed at the both ends of thick walled steel tube 2, the end 1 and end 28
On be all provided with there are one keyway, one end of counterweight roller 1 is fixed in the keyway of end 1.
In the present embodiment, the keyway on end 1 and end 28 is U-shaped, the hole size of end 1 and end 28
It is consistent with hearth roll axle journal, and design suitable fit clearance.Because having dive key, end 1 and end on hearth roll roll neck
28 endoporus processes the corresponding keyway of size therewith.Tool is undesirably fallen off with hearth roll in work progress in order to prevent, end
1 and end 28 on processing one be used for that the threaded hole of fastening screw is installed.
End 1 and end 28 and 2 integrally welded structure of thick walled steel tube, thick walled steel tube 2 will ensure the intensity of steel pipe,
In order to avoid the excessive influence work progress of bending deformation quantity, thick walled steel tube 2 uses welding structure with end 1 and end 28.Abutting end
Head is that plug-in is connect with the hearth roll diameter of axle, is reliably connected using fastening screw and hearth roll.
Counterweight roller 1 is the old hearth roll of same specification, and doing so avoids the making of clump weight, and make center of gravity just in tool
Midpoint, adjustment counterweight and the tedious work using additional suspender leveling when avoiding use.It is reused using finishing to match
Old hearth roll and this tool disintegrate, convenience in transport and storage.
With reference to attached drawing 2, to the hearth roll and the stove that can not use of other position roll change buggies at the neck of fire door
When bottom roller is replaced, it would be desirable to which the roll neck of the hearth roll of replacement is fixed together with end 28 by fastening screw 9, is used
Overhead traveling crane hangs the centre position of thick walled steel tube 2, and the replacement of hearth roll is completed in the case of not contacting hearth roll to be replaced outside stove
Work.
