Abstract
The utility model provides a change device of rolling mill roll, it comprises walking running gear, elevating system, horizontal migration mechanism hydraulic press and balancing unit, and elevating system and balancing unit install on walking running gear, and elevating system comprises elevating system, lift platform, and horizontal migration mechanism comprises horizontal migration hydraulic press, roll changing device joint, horizontal track, and horizontal migration hydraulic press and roll changing device joint are installed on horizontal track, and horizontal track is installed on lift platform. Because the utility model discloses a roll changing device of lift and horizontal mechanism, the precision is high when making the change roll, and not fragile equipment improves rolling mill life, and its structure letter, easy and simple to handle, roll change are efficient, save roll change time, adopt hydraulic drive mechanism to make its operate steadily, have increased the security reinforcing factor of safety of roll change.
Description
Technical field
The utility model belongs to the maintenance technique field of steel rolling equipment, specifically is a kind of device that is used to change rolling mill roll.
Background technology
At present, generally all adopt 20 roller sendzimir mills for producing cold rolled silicon steel and stainless steel field, because the special version of this milling train roll shape, adopt 1-2-3-4 type two layered tower rollers system, outermost 8 backing rolls and 6 two intermediate calender rolls need in the very correct plum blossom bore hole that is encased in mill housing.Its internal structure complexity, the wine made of broomcorn millet is in a lot of problems when installation, replacing, the mode that present domestic replacing support roller and two intermediate calender rolls all adopt crane to hang suspender is changed, there is following point: 1, owing to adopt steel cable to be flexible coupling between crane and suspender, appearance swings up and down and left and right sides precision is difficult to reach requirement, easily damage equipment.2, crane is when adjusting, because the required precision of roll change, when adjusting, the amplitude of fluctuation of crane is bigger, makes operating personnel injured easily.3, roll change program complexity, roll changing time is long.When changing support roller and two intermediate calender rolls, approximately need 16-18 hour at present.
The utility model content
The problem that the utility model exists when changing roll at above-mentioned milling train provides a kind of simple to operate easy-to-use, and the device of the replacing rolling mill roll that precision is high to reduce roll changing time, is enhanced productivity, and increases the roll change safety coefficient simultaneously, guarantees production safety.
The purpose of this utility model is to realize like this, a kind of device of changing rolling mill roll, it is characterized in that, it is to be made of running mechanism, elevating mechanism, horizontal mobile mechanism hydraulic press and bascule, elevating mechanism and bascule are installed on the running mechanism, elevating mechanism is made up of lowering or hoisting gear, hoistable platform, horizontal mobile mechanism is formed by moving horizontally hydraulic press, changing rig joint, horizontal rail, translation hydrodynamic press and changing rig joint are installed on the horizontal rail, and horizontal rail is installed on the hoistable platform.
Concrete structure of the present utility model has changing rig joint front end that winding device is installed.
Advantage of the present utility model and effect are, owing to adopt the changing rig of lifting and horizontal mechanism, make precision height when changing roll, be difficult for damage equipment, improve milling train service life, its structure letter, easy and simple to handle, roll change efficient height, save roll changing time, adopt hydraulic gear that it is operated steadily, the security that has increased roll change strengthens safety coefficient.
Description of drawings
Accompanying drawing is a structural representation of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing concrete structure of the present utility model is elaborated.
As shown in the figure, it is to be made of running mechanism 6, elevating mechanism, horizontal mobile mechanism and bascule 7 for the utility model, elevating mechanism and bascule 7 are installed on the running mechanism 6, elevating mechanism is made up of lowering or hoisting gear 4, hoistable platform 5, horizontal mobile mechanism is formed by moving horizontally hydraulic press 1, changing rig joint 2, horizontal rail 3, translation hydrodynamic press 1 and changing rig joint 2 are installed on the horizontal rail 3, and horizontal rail 3 is installed on the hoistable platform 5.
For fastening changing rig joint 2 front ends of the roll of its replacing are installed winding device 8.
Application process of the present utility model is such, when unloading roller, before by running mechanism 6 this changing rig being reached mill housing, make the horizontal rail of changing rig reach balance by bascule 7, by lowering or hoisting gear 4 lift platform 5 is promoted, changing rig joint 2 is aimed at roll, moving horizontally hydraulic press 1 inserts changing rig joint 2 and roll by horizontal rail 3 smoothly, and be fixed by winding device, roll is extracted out smoothly, put down bascule 7, start changing rig roll is placed on the platform, finish and unload roller.
During the dress roller, roll is fixed on the changing rig joint 2, before this changing rig reached milling train, make the changing rig equilbrium position that is up to the standard by bascule 7, by lowering or hoisting gear 4 lift platform 5 is promoted, this changing rig joint 2 is aimed at the milling train bore hole, move horizontally hydraulic press 1 and changing rig joint 2 and roll are packed in the rolling-mill housing smoothly, make the complete interlock of rack-and-pinion, roll is packed into smoothly by rotation by horizontal rail 3, and fastening roll, unclamp winding device 8 changing rig and roll are broken away from, finish roll change, put down bascule 7, changing rig is left, and installation is finished smoothly.
