Abstract
The invention belongs to the technical field of metallurgical steel rolling, and relates to replacing tools of tension rollers between rolling mill frames, in particular to a device for fast replacing a tension roller between rolling mill frames and a roller replacing method. According to the roller replacing method and the device, the tension roller between the rolling mill frames can be fast replaced. Compared with the prior art, the device and the roller replacing method have the advantages that the tension roller between the rolling mill frames can be fast replaced, the roller replacing time is shortened by more than 50 percent, and maintenance or repair time is greatly saved; the previous history without a tool special for roller replacing is finished, the phenomenon that a crane and a hoist crane are used previously for roller replacing to cause inclined pulling and drawing is eliminated, the occurrence probability of safety accidents is reduced, serious personal and equipment safety accident potential is reduced, and the problem of difficult roller replacing is solved; the structure is simple, implementation is easy, and operation is convenient.
Description
Technical field
The invention belongs to metallurgical technical field of steel rolling, relate to the replacing instrument of jockey pulley between mill stand, especially relate to the method and apparatus of jockey pulley between a kind of quick-replaceable mill stand.
Background technology
Certain steel mill is owing to limiting by production operation scene, there is no specific purpose tool, maintainer not easily nearby, changing jockey pulley between rolling mill production line frame very difficult, between each replacing frame during jockey pulley, is all at fore side with crane, the inside play, turnover back and forth between frame is hung in 4 cucurbits, change a jockey pulley and about need more than 6 hour, time-consuming, effort inefficiency, and there is the great person and device security hidden danger.
Summary of the invention
For overcoming the deficiencies in the prior art, the invention provides device and the roll-changing method of jockey pulley between a kind of quick-replaceable mill stand, adopt this changing rig and method, jockey pulley between quick-replaceable mill stand can be realized, overcome previous roll change crane and cucurbit to hang askew skewing and drag phenomenon, shorten roll changing time, reduce security incident probability of happening, decrease the great person and device security accident potential, solve the problem of roll change difficulty.
For achieving the above object, the present invention is achieved through the following technical solutions:
A device for jockey pulley between quick-replaceable mill stand, is made up of roll change buggy, track, it is characterized in that, described roll change buggy comprises vehicle frame and wheel, and vehicle frame is by structure steel fabrication, and wheel is connected as one by the wheel bearing on bolt and vehicle frame; Described track comprises channel-section steel one, channel-section steel two, adopts welding method to make; The wheel of described roll change buggy can roll back and forth in the groove of the channel-section steel one of track.
Described vehicle frame is provided with handspike and wheel bearing, and described wheel bearing bottom has groove.
The channel-section steel one of described track adopts back-to-back welding with channel-section steel two, and the groove of channel-section steel one upward.
The roll-changing method of jockey pulley between a kind of quick-replaceable mill stand, it is characterized in that, actual according to operation field, design roll change carriage special and track, when maintenance or repairing, its roll-changing method is: the first step is good and be lifted on track by roll change buggy track laying, roll change buggy advances between operation field mill stand by second step, 3rd step is removed jockey pulley and is placed on roll change buggy, old jockey pulley unloads and installs new jockey pulley by the 4th step pull-out roll change buggy, the roll change buggy that new jockey pulley is housed to advance between mill stand and installs jockey pulley by the 5th step again, 6th step pull-out roll change buggy, withdraw from track, roll change terminates.
Compared with prior art, the invention has the beneficial effects as follows:
1) adopt this roll-changing method and device, jockey pulley between quick-replaceable mill stand can be realized, shorten roll changing time more than 50%, greatly save maintenance or emergency repair time;
2) this roll-changing method and device is adopted, finish the history previously not having roll change specific purpose tool, overcome previous roll change crane and cucurbit and hang askew skewing and drag phenomenon, reduce security incident probability of happening, decrease the great person and device security accident potential, solve the problem of roll change difficulty;
3) structure is simple, is easy to realize, convenient operation.
