Abstract
The present invention relates to a kind of method for dismounting of the tangential keys for converter trunnion ring trunnion, include the following steps：1) through-hole is processed, in-site installation boring machine, boring bar faces trunnion end face, boring bar is retracted away from 600 650mm of trunnion end face, and left and right stroke ensures to process two groups of tangential keys simultaneously, and a drilling point two level performs, first 3 through-holes are bored respectively in tangential keys faying face with small diameter drill bit, reaming is to being dimensioned again, i.e., the distance between through-hole and through-hole are 1~3mm, and the distance between through-hole and tangential keys outer rim are 1~3mm；2) using through-hole as removal hole, drawing bar is welded in through-hole, drawing bar is pulled and takes out tangential keys.Advantage is：It is easy to operate, the other component in addition to tangential keys will not be damaged.This method for dismounting welds drawing bar only in 3 through-holes of tangential keys end face drilling in through hole, facilitates taking-up tangential keys, through overtesting, such mode is laborsaving, safe, and does not injure trunnion ontology.
Description
Technical field
The invention belongs to maintaining converter technical fields, are related to a kind of dismounting side of the tangential keys for converter trunnion ring trunnion
Method.
Background technology
There are 2 groups of tangential keys on the backing ring transmission side trunnion set on the converter installation of steel-making, work after a certain period of time, is cut
It to key and ontology fault, can not take out, use self-made tool steel plate, stud welding in the past, then pulled out by force with jack, there are people
Body is dangerous, injures trunnion ontology.To solve the problems, such as this, steel mill uses divided bearing, greatly reduces bearing use in this way
Service life and precision is bad.
Invention content
In order to overcome the deficiencies of the prior art, the object of the present invention is to provide a kind of tangential keys for converter trunnion ring trunnion
Method for dismounting facilitates tangential keys to dismantle, and does not damage trunnion ontology when tangential keys take out.
To achieve the above object, the invention is realized by the following technical scheme：
A kind of method for dismounting of tangential keys for converter trunnion ring trunnion, includes the following steps：
1) through-hole, in-site installation boring machine are processed, boring bar faces trunnion end face, and boring bar is retracted away from trunnion end face 600-650mm,
Left and right stroke ensures two groups of tangential keys of processing simultaneously, and a drilling point two level performs, first with small diameter drill bit in tangential keys faying face point
Not Zuan 3 through-holes, then reaming is to being dimensioned, i.e., the distance between through-hole and through-hole are 1~3mm, through-hole and tangential keys outer rim
The distance between be 1~3mm；
2) using through-hole as removal hole, drawing bar is welded in through-hole, drawing bar is pulled and takes out tangential keys.
The distance between the through-hole and through-hole and the distance between through-hole and tangential keys outer rim are equal.
Compared with prior art, the beneficial effects of the invention are as follows：
This method for dismounting is easy to operate, will not damage the other component in addition to tangential keys.This method for dismounting is only in tangential keys
3 through-holes of end face drilling, and drawing bar is welded in through hole, facilitate taking-up tangential keys, through overtesting, such mode is laborsaving, peace
Quan Xinggao, and trunnion ontology is not injured, it is economic and practical.
Description of the drawings
Fig. 1 is the working state figure of the present invention.
Fig. 2 is the structure diagram of tangential keys.
Fig. 3 is the structure diagram of wedge key.
In figure：1- tangential keys 2- trunnion 3- trunnion block 4- through-hole 5- wedge keys.
Specific embodiment
The present invention is described in detail with reference to the accompanying drawings of the specification, it should be noted that the implementation of the present invention is unlimited
In following embodiment.
See Fig. 1-Fig. 3, a kind of method for dismounting of tangential keys for converter trunnion ring trunnion, tangential keys are by two wedge keys 5
Rectangular parallelepiped structure is formed, through-hole 4 is processed at the faying face between wedge key 5, the distance between through-hole 4 and through-hole 4 b are 1~3mm,
The distance between through-hole 4 and 1 outer rim of tangential keys a are 1~3mm.The distance between through-hole 4 and through-hole 4 b and through-hole 4 and tangential keys 1
The distance between outer rim a is equal or │ a-b │≤1mm.After processing through-hole 4, the welding drawing bar in welding in through-hole 4,
And extend to outside tangential keys, it pulls drawing bar and can be taken off tangential keys 1.Whole operation process will not be damaged in addition to tangential keys 1
Other component.
Embodiment
For tangential keys 1 for 260 tons of converter trunnion ring transmission side trunnions 2：
See Fig. 1, there is 2 groups of tangential keys, 1,120 degree of direction arrangements, every group of tangential keys 1 between transmission side trunnion 2 and trunnion block 3
A cuboid is formed by two wedge keys 5, size is 144 × 200 × 1400mm.
See Fig. 2, Fig. 3, for the method for dismounting of the tangential keys of converter trunnion ring trunnion, include the following steps：
1) through-hole 4 is processed：In-site installation boring machine, boring bar face 2 end face of trunnion, and boring bar is retracted away from 2 end face 600- of trunnion
650mm (ensure 600 long drill bits can be loaded), left and right stroke guarantees to process two groups of tangential keys 1 simultaneously, boring machine boring bar and
Dial gauge presses 2 end face centering of trunnion, and error≤0.1mm is firm by boring machine pad with gasket, is fixed lathe and steel billet with bolt.It bores
Hole point two level performs, and first bores 3 through-holes 4 respectively in 1 faying face of tangential keys with small diameter drill bit, then reaming is to desired sizeThree are processed at 2 tangential keys of trunnion, 1 edge seam successivelyThrough-hole 4, make between through-hole 4 and through-hole 4
Distance b, the wall thickness a between through-hole 4 and edge is 2mm, then 1 part of tangential keys is hollow, stress change, the lapping-in with ontology
Power reduces, and can just be pulled out tangential keys 1 with the power of very little again in this way；
2) using through-hole 4 as removal hole, the welding drawing bar in through-hole 4, drawn stem divides stretching tangential keys 1, pulls and draws
Dead man takes out tangential keys 1.
During practical operation, according to the size of converter trunnion ring trunnion 2, the size to drill is needed also to change, but must assure that a with
The value of b is 2 ± 1mm.
