Technical scheme also comprises more specifically: described base is provided with base wheel.
Further: described lifting mechanism comprises the jack that is fixed on main platform support column, the piston of described jack is fixedly connected with lifting platform.
Further: described transverse sliding mechanism comprise be fixed on lifting platform surface transverse shifting guide rail, be connected in the pinch roller of hold-down cylinder fixed head lower end, described pinch roller and transverse shifting guide rail connect into transverse sliding mechanism.
Further: described jack is fixed on the middle part of main platform gripper shoe.
Further: to be at least provided with hoisting guide mechanism at described jack two ends.
Further: described transverse sliding mechanism comprise be fixed on lifting platform surface transverse shifting guide rail, be connected in the anti-tipping pinch roller of hold-down cylinder fixed head lower end, described transverse shifting guide rail is I-steel guide rail, the fixing pinch roller seat of described anti-tipping pinch roller is hinged, curved in both sides, described pinch roller seat bottom, be stuck in and in the both sides I-shaped steel tank of described transverse shifting guide rail, prevent that hold-down cylinder fixed head from tumbling.
The utility model has the advantages that:
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 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 together has not occurred;
5, stop the pollutions such as dust, arc light, steam, noise, protected the healthy of worker, and provide more sturdy basis for environment protection health system optimization.
