With the adoption of the roll body online grinding device, the labor intensity of a maintenance operator can be greatly reduced, the degree of safety of the maintenance operator can be greatly improved, the efficacy of maintenance and operation can be also greatly improved, and the maintenance cost is lowered; and the roll body online grinding device has a simple structure and is convenient to operate, popularize and implement.
Description
Technical field
The utility model relates to a kind of flight-line maintenance device, and more particularly, the utility model relates to a kind of maintenance unit of metallurgical machinery.
Background technology
The steel plate aligning is the important procedure of hot rolled steel plate factory and office reason steel plate finished product.Because there is residual stress in the steel plate in the operation of rolling, therefore cause steel plate generation plastic deformation, wooden dipper song, to this, must align promptly steel plate by thermal straightening machine: allow steel plate by aligning roll gap default on the thermal straightening machine, just can make steel plate under the aligning repeatedly of smoothing roll, eliminate remaining stress, overcome plastic deformation, recover elastic stage, thereby guarantee the straight of finished product steel plate.
In the aligning process, because smoothing roll frequently contacts with steel plate, the steel plate head sharp edge smoothing roll body of roll of damaging is often arranged, or remaining iron scale is piled up and is caused aligning body surface and impression, salient point occur on the steel plate, and the scratch on the body of roll, playing heap, salient point conversely can the scratch surface of steel plate, causes vicious circle.
Therefore, Heavy Plate Plant has scratch if find steel plate in process of production, productions of all can stopping the very first time, inspection smoothing roll, and impaired smoothing roll carried out reconditioning.Traditional grinding method comprises the steps: the smoothing roll roll gap is risen to maximum height, on four angles of straightener up-down rollers box, place safe cushion block, input and output roller-way before and after the straightener is had a power failure, the hand-held hand frosted turbine of operating personnel is climbed to smoothing roll box middle inspection reconditioning straightener body surface up and down then.Because maintenance environment temperature height, operating condition is abominable, and this inspection reconditioning mode is relatively more dangerous, and labor intensity of operating staff and danger are bigger, in case maloperation is arranged or do not note even can cause the reconditioning personnel casualties.Thereby improve the maintenance security in order to reduce artificial hand-held reconditioning, the technological improvement of the body of roll arrangement for grinding that adopts resilient engagement is arranged, but traditional resilient engagement arrangement for grinding, and its structural design is unreasonable: perhaps too complicated, the operation inconvenience of mechanism; Perhaps adopt the matrix flexibility and the thin reconditioning body of abrasive material, must frequent change the reconditioning body in the operation, cause that grinding efficiency is low, maintenance cost is too high, be difficult to promotion and implementation.
Summary of the invention
Above-mentioned shortcoming at prior art, the purpose of this utility model is to provide a kind of body of roll online arrangement for grinding, it has following advantage: can significantly reduce maintenance operation personnel's labour intensity, significantly improve maintenance operation personnel's safe coefficient, and can significantly improve the effect of maintenance operation, reduce maintenance cost, and simple in structure, easy to operate, be convenient to promotion and implementation.
For this reason, technical solution of the present utility model is the online arrangement for grinding of a kind of body of roll, it comprises the projection of the two cambered surfaces of band, with recessed of single cambered surface, offer the caulking groove of assembling reconditioning body on the described cambered surface, in the described recessed groove that flexibly is slidingly fitted in the projection back side, and described caulking groove is along the two ends that vertically connect described arrangement for grinding as the crow flies of described arrangement for grinding.
The utility model is being faced on the cambered surface of the body of roll to be grinding, along arrangement for grinding the vertical that is body of roll to be grinding vertically, offer the caulking groove of the straight perforation of assembling reconditioning body, thereby, in the caulking groove of straight perforation, both can the thin flexible reconditioning body of scarf abrasive material, the rigidity reconditioning body of the scarf abrasive material richness of being more convenient for.Because rigidity reconditioning body has the rich and continuous advantage of total length of abrasive material, with the utility model arrangement for grinding be placed on up and down in the middle of the smoothing roll, simultaneously when smoothing roll is implemented online reconditioning up and down, can significantly reduce maintenance operation personnel's labour intensity, significantly improve maintenance operation personnel's safe coefficient, and, reconditioning body of the present utility model can treat to do continuous gapless reconditioning on the vertical total length of grinding roller body or the most of length, does not need continually to move in the vertical with balance reconditioning degree difference, fills up the gap of not reconditioning; The rigidity reconditioning body of abrasive material richness not only fully reconditioning treat the grinding roller body, and, a common rigidity reconditioning body can be done repeatedly the body of roll, many reconditionings and needn't changing, and so, the utility model arrangement for grinding just can significantly improve effect, the reduction maintenance cost of maintenance operation; It is evident that in addition the utility model is simple in structure, that operation is adjusted is very convenient, be convenient to promotion and implementation.
For further optimizing structure, improve the convenience and the dismounting efficient of operation, thereby improve effect, the utility model comprises that following concrete structure improves:
Described caulking groove cross section is a T shape: comprise the bottom land of wide spacing and the notch of thin space.
Described arrangement for grinding comprises that also activity is assemblied in the I shape reconditioning body on the described T shape caulking groove total length.
Be further to increase the interchangeability of reconditioning body, improve the convenience of operation and efficient and further reduce cost that the utility model comprises that following concrete structure improves:
Described I shape reconditioning body comprises the reconditioning plate of pair of parallel, and parallel reconditioning board size is identical; The cross section of all T shape caulking grooves of offering on the described arrangement for grinding has identical shaped and size.
For further increasing the adaptability of reconditioning body, improve flexibility, the whole conveniently moving of maintenance operation, the utility model comprises that following concrete structure improves:
Described reconditioning body is that rigidity friction material and/or flexible material are made; Described projection both sides also offer the hanger hole.
For further increasing reliability, the adaptability of the frame for movement of arrangement for grinding, improve grinding quality and operating efficiency, the utility model comprises that following concrete structure improves:
