Detailed description of the invention
A kind of roll change bracket of the present utility model, comprises and is placed in ground lower roller change bracket 1, is positioned at the lower displacement apparatus on lower roller change bracket 1 and is positioned at the upper deflector roll bearing of lower roller change bracket 1 top.
On lower roller change bracket 1, welding or bolt are bolted to the earrings 2 on milling train while having work, utilize earrings 2 to be bolted on milling train thereby accomplish to change lower roll 7 to be replaced, and while not needing to change, lower roller change bracket 1 are removed, thereby ensured field activity environment spaciousness.
Lower displacement apparatus is arranged at the end face of lower roller change bracket 1, and this lower displacement apparatus comprises the snub pulley 4 that at least 2 groups that are positioned on lower roller change bracket 1 are arranged side by side, and lower roll 7 to be replaced is placed on snub pulley 4.When concrete operations, by the earrings 2 on lower roller change bracket 1 is bolted on milling train, now lower roll to be replaced is hauled out gently and make it to be partly held on the snub pulley 4 on lower roller change bracket 1, the snub pulley 4 that these at least 2 groups that arrange on roller change bracket 1 are at present arranged side by side is equivalent to provide a confession lower roll 7 to be replaced friction of rolling thereon, do not need thereby drag for lower roll 7 to be replaced the strength that costs a lot of money, thereby can easily lower roll to be replaced be taken out.
On lower roller change bracket 1, be provided with the upper roller change bracket being bolted to directly over lower roller change bracket 1, on this, roller change bracket comprises upper bracket 5, is positioned at the upper supporting roller 6 that at least 2 groups on upper bracket 5 are arranged side by side, the lower roller change bracket base cross members 3 that welding is arranged at upper bracket 5 belows, and top roll 8 to be replaced is placed on upper supporting roller 6.When concrete operations, by the earrings 2 on lower roller change bracket 1 is bolted on milling train, now upper deflector roll is hauled out gently and make it to be partly held on the upper supporting roller 6 on upper bracket 5, the upper supporting roller 6 that at least 2 groups that now arrange on upper bracket 5 are arranged side by side is equivalent to provide a confession upper deflector roll to be replaced friction of rolling thereon, do not need thereby drag for upper deflector roll to be replaced the strength that costs a lot of money, thereby can easily upper deflector roll be taken out.
Due to higher apart from ground, therefore can there is the risk of toppling in above-mentioned upper deflector roll bearing, therefore improved by spacing and overturn-preventing structure is set on upper bracket 5.Concrete: upper bracket 5 is provided with overturn-preventing structure near welding in upper bracket 5 left end of top roll 8 to be replaced, this overturn-preventing structure comprises the overturn-preventing bearing and the guide wheel that is positioned at this overturn-preventing bearing top of vertically placing of vertical placement, and guide wheel is against on top roll 8 to be replaced.Upper bracket 5 is provided with position limiting structure near the upper bracket 5 right-hand end welding of top roll 8 to be replaced, and this position limiting structure comprises and is hinged on the limiting stopper of described upper bracket 5 right-hand end and is fastened to the screw on described upper bracket 5 through limiting stopper.Above-mentioned position limiting structure is in work time-division two steps, when in first step, top roll 8 to be replaced is not placed on top base completely, by screw, limiting stopper is fastened on top base, in second step, top roll 8 to be replaced is placed on top base completely and is, by taking off this screw, thereby make limiting stopper around itself and top base hinge-point moving, directly go out from position limiting structure one side-draw thereby be convenient to top roll 8 to be replaced.
In order to realize single unit system stress equalization, on the lower roller change bracket bottom surface between lower roller change bracket and ground, be at least provided with 4 feets, if four, these 4 feets are distributed on four jiaos of lower roller change bracket bottom surfaces.
For the ease of regulating the height up and down of upper roller change bracket, make it concordant with top roll to be replaced, between upper bracket 5 up and down roller change brackets 1, be provided with lift adjustment part 10, this lift adjustment part 10 is for being vertically arranged on the bolt on lower roller change bracket 1 and being threaded in the nut on this bolt, and this nut is connected on upper bracket 5.
To topple when preventing from changing top roll 8 to be replaced, to be provided with guide frame 11 on upper bracket 5, guide frame 11 is positioned at the same side with earrings 2.Guide frame 11 comprises and is the guiding trestle of door type and is fixedly installed on the guide wheel 12 on guiding trestle, and top roll 8 to be replaced is through the guiding trestle that is door type, and guide wheel 12 props up on the periphery of this top roll 8 to be replaced.
In order to change easily top roll 8 to be replaced, upper roll change is propped up, hingedly on 5 be provided with rotatable limiting stopper 13, rotatable limiting stopper 13 is arranged at upper bracket 5 ends away from guide frame 11, and rotatable limiting stopper 13 props up top roll 8 to be replaced in the time just changing top roll to be replaced completely.
Specific works principle and process are as follows: while changing lower roll 7 to be replaced, utilize earrings 2 that the lower roller change bracket 1 in the utility model device is fixedly installed on mill.Then lower roll 7 to be replaced is pulled out, lower roll 7 to be replaced can be hung away afterwards.And new lower roll to be replaced 7 is winched on snub pulley 4, complete roll change.
While changing top roll to be replaced, upper bracket 5 is placed on lower roller change bracket 1, control 10 liftings of lift adjustment part, ensure that upper bracket 5 is concordant with top roll to be replaced, now top roll 8 to be replaced is drawn out on upper bracket 5, opens rotatable limiting stopper 13 hinged on upper bracket 5, afterwards top roll 8 to be replaced is hung away, new top roll to be replaced 8 is winched on carrying roller, complete top roll 8 to be replaced and change.
Above the invention embodiment is had been described in detail, but described content is only for the preferred embodiment of the invention, can not be considered to the practical range for limiting the invention.All equalization variation and improvement etc. of doing according to the invention application range, within all belonging to the patent covering scope of the invention.
