Description
Technical field
The utility model relates to a kind of steel rolling equipment field, specifically a kind of roll-changing equipment with positioner.
Background technology
At present, in cold-rolled strip enterprise, in steel band Rolling Production process, often because working roller abrasion, damage or steel band change, roll specification, need dismounting and change working roll.General enterprises is changed working roll, still adopts manual operation balance sling, or the method such as crane, crowbar cooperation.These roll-changing methods, inefficiency, labour intensity is large, and roll changing time is long, influence of rolled production output.In the prior art, having the patent No. is the utility model patent of 201120143136.X, and a kind of simple in structure, roll-changing equipment of shortening roll changing time, easy to operate, practical operation roll of mill is provided.Improve maintenance of equipment speed, alleviated workman's amount of labour.But in use, because bottom is provided with roller, when roll change, frame easily moves, make location inaccurate.Particularly when mounted, easily produce and rock, and because the weight of working roll is large, when rocking, be difficult to stablize, brought certain difficulty therefore to roll change operation.
Summary of the invention
The purpose of this utility model, is exactly the problem existing for solving prior art, and has designed a kind of roll-changing equipment with positioner, has guaranteed the stable of when changing working roll equipment, improves roll change speed.
The technical solution of the utility model is: a kind of roll-changing equipment of operation roll of mill, include traversing carriage, on support, by roller, connect an elevating mechanism, on elevating mechanism, level is equipped with support bar, and the free end of support bar is provided with hook, and hook is installed in rolling-mill housing, support is provided with the lifting hydraulic cylinder that drives elevating mechanism, elevating mechanism is provided with the telescopic hydraulic cylinder that drives support bar, in the bottom of support, is provided with walking roller, and the bottom of described support is provided with positioner.
Described positioner is positioning support leg or roller positioner.
Described roller positioner is the disc brake device being arranged on roller shaft.
Described positioning support leg is hydraulically extensible supporting leg, includes outer tube, is provided with hydraulically extensible bar in outer tube, and the external part of expansion link is provided with supporting seat.
Described supporting seat is comprised of two mutual cross support bars, and one end of support bar and expansion link is hinged.
The outside of described support bar is provided with anti-slip rubber layer.
Described positioner is at least provided with three.
The beneficial effects of the utility model can draw by such scheme: owing to being provided with positioner in frame bottom, make the stable of when changing working roll equipment, improve roll change speed.Described positioner is selected disc brake device, and it is simple for structure, and control dynamics is good, easy to use.When positioner choice for use positioning support leg, the advantage such as positioning support leg has accurate positioning, and support degree is large.And this programme adopts the supporting seat of positioning support leg to have supporting & stablizing, shrink feature easily, be very easy to the installation of working roll.The utility model is simple in structure, easy to operate, and roll change process stabilization is quick.
As can be seen here, the utility model compared with prior art has substantive distinguishing features and progress, and the beneficial effect of its enforcement is also apparent.
