Description
Technical field
The present invention relates to the maintenances of sour rolling plant, roll loop steel rope replacing more particularly to acid.
Background technique
Cold rolling horizontal loop is to be applied to cold rolling acid rolling line, is that whole sour rolling line realizes quantity-produced important equipment, base
There are 3 loops on every sour rolling line in sheet, loop capital equipment includes loop trolley, wirerope, hydraulic cylinder, loop door, bottom roller
Etc. equipment composition.Its major function is storage strip, is entrance change of lap, and welding provides sufficient buffer time.Loop is cold rolling
One of important equipment, since wirerope possesses sufficiently large tensile force for a long time, wirerope is caused to be chronically at tight state, steel
Cord is easy to fracture of wire occur, it is therefore desirable to according to live wirerope concrete condition, carry out irregular replacement to wirerope.This
It is a large labor intensity, the process of low efficiency during upkeep operation.
Summary of the invention
The present invention is directed to improve working efficiency, a kind of acid is provided and rolls loop steel rope replacing method.The present invention improves acid
The replacement efficiency for rolling loop wirerope, reduces labor intensity.
In order to solve the above-mentioned technical problem, the present invention is implemented as follows:
A kind of acid rolls loop steel rope replacing method, includes the following steps:
Step 1: loop trolley is parked in full set position；
Step 2: tripartite confirms, has a power failure, is listed；
Step 3: loop trolley is fixed on extreme position with wirerope with jack, prevent in replacement and fastening steel wire rope
When trolley it is mobile；
Step 4: being fixed hydraulic steel wire rope cylinder head with jack, blocked after tension with clamp；Hydraulic cylinder is slowly returned
It puts, is put into the position of the limit, the clamp of fixed wirerope is unclamped, and the tongue of the hydraulic cylinder head is got with sledgehammer,
Wirerope is taken out, slowly unclamps jack, wirerope is unloaded into tension completely, the clamp of fixed jack is removed；
Step 5: one directive wheel of production, another fixing end of wirerope is removed, and be passed through fixing in advance
Directive wheel pulls out loop；Old rope and new rope welding are finished with gas welding；
Step 6: notice point inspection and operation, crawl rotate rope sheave driving, wirerope are slowly pulled out loop with fork truck, in
Between special messenger follow pad to walk, checking wirerope, whether there is or not scratch place, the old wire rope directive wheel, by its several times change side
To export loop, smoothly fork truck can be allowed to draw, take loop out of until all old wire rope wholes；
Step 7: old wire rope is cut off with gas welding, new wirerope is fixed on fixing end；The other end is drawn with jack
Tightly, and by steel wire penetrating hydraulic cylinder cylinder head, wirerope is fixed, jack is unclamped, is tensed wirerope with hydraulic cylinder, and will be fallen
Chain tenses, and wirerope is put rope by the hydraulic cylinder that comes up outward again；It fixes, tenses loop wirerope with hydraulic cylinder again,
Jack is unclamped, until tightness of steel wire rope is suitable；Wirerope is fixed；
Step 8: the wirerope for closing trolley is removed, pack up, live 6S work；
Step 9: tripartite confirms that delisted, power transmission send pressure, test run.
The acid rolls loop steel rope replacing method, directive wheel described in step 5, including two 12mm thick steel plates
The C-shaped frame that is welded is sub, fixes two dish axle of band in an idler wheel among C-shaped frame and holds, be accompanied with lifting lug device above shelf, uses
In stator ring.
The acid rolls loop steel rope replacing method, during steel rope replacing described in step 6, utilizes self-control
Pulley wirerope deflecting is exported into loop, and pull it loop with fork truck.
The present invention improves the replacement efficiency that cold rolling acid rolls Horizontal type loop wire rope, reduces because the reason of replacing options makes
At site environment pollution, save cost of labor when replacement, reduce labor intensity.
Specific embodiment
