Description
Technical field
The present invention relates to the Mill Technology field, particularly relates to a kind ofly press-fiting cylinder change on steel mill carrying out for plate mill, press-fits the milling train hold-down cylinder device that cylinder changes on the milling train that particularly is applied in cut deal carries out and changes system.
Background technology
Existing technology is exactly the suspender provided according to former milling train factory, take full advantage of driving major and minor hook synchronous or asynchronous movement and by the ground staff, command accurately, the overhead traveling crane operating personnel are careful to be observed, meticulously operates, constantly fine setting, find and change the suitable position of hold-down cylinder, when suspender, under overhead traveling crane coordinates, enter in mill housing while removing hold-down cylinder, the hold-down cylinder that dismounting is fixed on to suspender one end exits mill housing and pulls down old hold-down cylinder outward.After new cylinder is fixed by bolts to suspender end place, inferior entering in the memorial archway body, installed, this process will be repeatedly three times, just can complete.In this process, because hold-down cylinder is embedded in suitable little of memorial archway internal clearance, must prizes cylinder body with drill rod by manpower, and follow shaking of suspender, slowly cylinder body is pulled down from memorial archway, and then commander's overhead traveling crane hangs out.Total process approximately 155 minutes.
There are the following problems for above-mentioned prior art:
1) Renewal process is cumbersome, the more and more difficult control of unfavorable factor., there are many uncontrollable factors the aspects such as methods of working in coordination, changing from overhead traveling crane operation, ground staff commander, work.Approximately 14000 meters of suspender length, the about 400Kg of hold-down cylinder, the staff is 9 people approximately, change normal condition all repeated multiple times at every turn, meet hold-down cylinder sometimes in the situation that dress does not advance, and also will do over again, very trouble;
2) unsafe factor is many.When changing, outside memorial archway, suspender counterweight place needs 5 workers to shake suspender, and memorial archway domestic demand 2 people compress cylinder body, approximately 1 square metre of memorial archway inner area with the drill rod sled.
3) one of them link goes wrong, and all will damage personnel, and a lot of hold-down cylinder industrial accidents of changing just once occurred in the past;
4) the replacing time longer, can not adapt to the requirement of rhythm of production.
5) automaticity is lower.In replacing with the whole process of hold-down cylinder, be exactly all to rely on manpowers basically, become physical property technical, worker's labour intensity is very large, and its subjective initiative is subject to larger restriction;
6) owing to inevitably using electric welding, oxyacetylene metal-cutting in the course of work, the dust produced, arc light, steam, noise pollution, not only efficiency is low, and the healthy of worker worked the mischief.
Summary of the invention
Purpose of the present invention just is to provide a kind of efficient, safe, quick higher frock that replaces with hold-down cylinder of automaticity, can solve the drawback that prior art exists after coming into operation fully.The replacing milling train hold-down cylinder device that is highly suitable for hold-down cylinder on existing Heavy Plate Plant milling train is changed system.
Solution of the present invention is such:
The present invention has base, and main platform support column and the main platform gripper shoe of described base are hinged to rotational structure; Described main platform gripper shoe is provided with lifting mechanism, the lifting platform of described lifting mechanism is provided with transverse sliding mechanism, the sliding end of described transverse sliding mechanism is connected with the hold-down cylinder fixed head, forms the structure that the compressed oil cylinder fixed head can laterally slide and upper and lower lifting is moved.
Technical scheme also comprises more specifically: described base is provided with the base wheel.
Further: described lifting mechanism comprises the jack that is fixed in main platform support column, and the piston of described jack is fixedly connected with lifting platform.
Further: described transverse sliding mechanism comprises the transverse shifting guide rail that is fixed on the lifting platform surface, the pinch roller that is connected in hold-down cylinder fixed head lower end, and described pinch roller and transverse shifting guide rail connect into transverse sliding mechanism.
Further: described jack is fixed in the middle part of main platform gripper shoe.
Further: at least at described jack two ends, be provided with hoisting guide mechanism.
Further: described transverse sliding mechanism comprises the transverse shifting guide rail that is fixed on the lifting platform surface, the anti-tipping pinch roller that is connected in hold-down cylinder fixed head lower end, described transverse shifting guide rail is the I-steel guide rail, fixedly the pinch roller seat is hinged for described anti-tipping pinch roller, curved in both sides, described pinch roller seat bottom, be stuck in the both sides I-shaped steel tank of described transverse shifting guide rail and prevent that the hold-down cylinder fixed head from tumbling.
Advantage of the present invention is:
1, this fixture system is directly changed on track and is designed at former rolling mill roll, and floor space is little, and Fixture Design is simple and direct efficient, is applicable to all Heavy Plate Plant;
2, this frock is simple and practical, workable;
3, this fixture system, owing to can realize the synchronization line of installing and changing simultaneously, has significantly reduced the replacing time, boosts productivity; Can realize accurate location, and greatly alleviate workman's labour intensity;
4, because the automaticity degree is higher, the emphasis of worker's work transfers this equipment of operation to, and safety factor improves greatly, since using this frock, the problem of secure context has not together occurred;
5, stop the pollutions such as dust, arc light, steam, noise, protected the healthy of worker, and provide more sturdy basis for the environment protection health system optimization.
