Description
Technical field
The utility model relates to the roller-way roller that uses in a kind of steel rolling equipment roller-way transportation, belongs to the steel rolling equipment technical field.
Background technology
Roller-way transportation is one of main mode of metallurgy industry material transportation, and its maximum characteristics transportation range is long, and roller quantity is many, tens at least of roller-ways, at most tens up to a hundred individual.In the prior art, the design of roller all is the body of roll of tubular, and two ends are supported with disc, middle axle, three kinds of rollers that part is welded to form, refill mix the bearing shaft bearing after, form the roller build-up member, be installed on the roller bed frame.This design characteristic is: simple in structure, for the first time the input expense is lower, and roll surface, axle, disc, bearing etc. should same Life Design, and integral body is scrapped when roll surface wearing is scrapped.And in real work, on-the-spot various working conditions change are very big, and the roll surface wear situation varies; Especially in the steel rolling industry, a large amount of roller roll surfaces and the contact wear of high temperature steel, the roll surface life-span is generally low; That have even have only several days time, just grind groove, played rib; Cause steel surface to scratch, influence product quality.Serious become quality accident, cause quality objection.In this case, the roll surface of wearing and tearing need be changed by a large amount of subsequent use rollers, and must have big time to change.But because steel rolling production has the successional production characteristics of serial; Do not allow again and remove large batch of replacing roller long downtime, at this moment, can only utilize technology to change the on-the-spot polishing of the hand-held abrasive machine of pass arrangement of time personnel; Do interim processing temporarily, but poor effect.
Through field investigation and analysis, the roller that uses at present exists following abrasion condition and handling characteristics:
1, at the scene under the working condition, roller roller surface wear position is relatively concentrated the fixed position mostly, and how other part roll surface weares and teares hardly, also can continue to use, if replacing will cause waste comprehensively;
2, axle, disc, bearing etc. far do not reach service life, must just can take off axle and disc from former weld bond with gas welding but will reuse, and life size is replied in processing again again; When with gas welding the roasting heat of bearing being taken off equally, axle temperature distortion, bearing life greatly reduces; Simultaneously, repair input material, compare roughly suitable like this with new manufacturing cost with artificial more; Therefore in most cases no longer repair, whole roller is done and is scrapped processing.
3, replacing is wasted time and energy, and can only overhaul integral replacing, can not make full use of technology and do effective processing downtime, and grinder buffing etc. are helpless interim measure, can not solve root problem.
Therefore, press for a kind of roll surface of design can make things convenient for fast change, be convenient to repair, roller that expense is lower, to reduce reserve level, reduce the replacing time, to improve operating rate, meet the needs of production.
The utility model content
But the utility model technical problem to be solved provides a kind of roller-way roller that can be convenient to dismounting and on-line replacing, minimizing shutdown polishing time, cut the waste and reduce cost, improve the split replacing roll surface of operation rate and production operational availability.
The technical scheme that solves the problems of the technologies described above is:
But the roller-way roller of roll surface is changed in a kind of split, and it comprises the body of roll, roll shaft, two ends disc, and the two ends disc is set in the roll shaft two ends; Its improvements are, the described body of roll be identical four semicircle bodies of roll according to rearranging up and down, on roll shaft, increased middle interradial plate; Middle interradial plate is positioned at two ends disc central authorities; Parallel with the two ends disc, two semicircle bodies of roll are up and down arranged respectively between middle interradial plate and right ends disc, at the two ends of the body of roll end cap is installed also; End cap is evenly distributed in screw; Have a plurality of screws and end cap screw to be complementary on the disc lateral wall of two ends, four semicircle body of roll framves on the disc of two ends, four semicircle body of roll two ends respectively with middle interradial plate and two ends end cap for removably connecting.
But the roller-way roller of roll surface is changed in above-mentioned split; There is arc groove the both sides of the edge of interradial plate circumference in said; There is arc groove the inboard of two ends end cap circumference; There is arc-shaped convex at the two ends of each semicircle body of roll, and the arc-shaped convex at four semicircle body of roll two ends is complementary with the arc groove of middle interradial plate, two ends end cap respectively.
But the roller-way roller of roll surface is changed in above-mentioned split; The edge of interradial plate circumference and two ends disc circumference has keyway respectively in said; There is keyway at the two ends of each semicircle body of roll, and the keyway at four semicircle body of roll two ends is complementary with the keyway of middle interradial plate, two ends disc circumference respectively.
The usefulness of the utility model is:
The body of roll is the dismantled and assembled structure of split, can carry out the part roll surface and change, and realize changing between all right 180 degree of roll surface itself and left and right sides roll surface and use, and has significantly reduced the consumption of roll surface spare part like this, has practiced thrift expense, has reduced cost;
With the disassembly process design simplification is the dismounting of several bolts, has reduced workload, has improved replacing speed; Utilize roller to turn characteristics; Assembling-disassembling bolt turns only angle, is convenient to operation, shortens the dismounting time and can realize utilizing technology downtime; The indivedual replacing reduced the big concentrated replacing time of section;
The utlity model has technical scheme structure reasonable, simple and practical, fully adapt to the advantage of on-site actual situations, compare with common roller of past and have a good application prospect and economic benefit.
