The specific embodiment
Fig. 1-2 illustrates the embodiment according to the utility model milling train prestressing combination frame.
Shown in Fig. 1-2, milling train prestressing combination frame of the present utility model comprises entablature 1 and sill 4, and is arranged on the many root posts 2 between the lower and upper cross-member, and lower and upper cross-member is connected by suitable jockey with each column.In Fig. 1-2 illustrated embodiment, combined rack comprises four four root posts that are symmetricly set on place, four bights respectively.
Fig. 2 illustrates an embodiment who realizes that crossbeam is connected with column.As shown in Figure 2, entablature is formed with flange 15 (in order to express easily, directions X is called laterally among Fig. 1, and the Y direction is called vertically among Fig. 2) at its lower end, is formed with through hole 5 on each flange 15 respectively; And sill locates also to be formed with flange 16 in the top, is formed with through hole 6 respectively on each flange 16; In addition, each column also is formed with an axially extending bore 7 respectively.Lower and upper cross-member and column connect by means of bar 8, and bar 8 is formed with external screw thread respectively at its place, axial two ends.
In the assembling process of combined rack, at first the through hole 7 on through hole on the lower and upper cross-member 5,6 and the column is axially aligned, then bar 8 is inserted wherein, by the nut 9 of spinning on bar 8 end external screw threads each building block is coupled together at last.By adjusting the power that screws of nut 9, can adjust the pressurized degree of each column, thereby make column produce predetermined compression, make the integral rigidity of combined rack be improved.
Among the embodiment that addresses in the above, connect by a root post at each place, bight of lower and upper cross-member, but the insider be it is evident that, each place, bight of lower and upper cross-member can connect by some root posts according to actual needs.
In addition, in the above embodiments, column is shaft-like form, but need to prove that here column is not limited to shaft-like form, but can adopt other forms of column.Such as, two columns on two columns in left side and right side can be respectively overall structure among Fig. 1, that is two left columns form a monoblock type sheet-pile shape column, and two right columns form a monoblock type sheet-pile shape column.Under the situation that adopts sheet-pile shape column, two sheet-pile shape columns are oppositely arranged, and by bar 8 and nut lower and upper cross-member and each sheet-pile shape column are coupled together to constitute frame.
Fig. 3 illustrates another embodiment that realizes that crossbeam is connected with column.The difference of connected mode shown in Figure 3 and connected mode shown in Figure 2 is: the nut that is positioned at the top is substituted by a fluid cylinder 10.As shown in Figure 3, fluid cylinder 10 is arranged on the place, bight of entablature, and it comprises a cylinder body 11 and is provided in bar piston 12 8 upper ends, that be arranged in cylinder body.One aperture 13 is formed on the wall of cylinder body in the piston below.When carrying out the assembling of combined rack, by the pressure fluid of predetermined pressure being injected fluid cylinder piston jack-up is linked together each parts, and the compression that produces in column can be regulated by regulating fluid pressure via aperture 13.
In addition, a remodeling embodiment who is connected with column as crossbeam can replace nut in embodiment illustrated in fig. 2 with the hydraulic locking nut.
Adopt milling train prestressing combination frame of the present utility model, at first processing and manufacturing is as lower and upper cross-member and each column of individual components, utilize bolt or fluid cylinder and bar that lower and upper cross-member and each column are interconnected then in composing room or erecting bed and constitute a combined rack, and the prestressing force that column bore can be regulated according to actual needs.After assembling frame,, thereby assemble milling train with being installed in the installing space of lower and upper cross-member and the qualification of each column of milling train such as milling train parts such as working roll, backing rolls.
Fig. 4 and Fig. 5 illustrate another embodiment of the utility model composite machine frame of mill.
As everyone knows, milling train is in the operation of rolling, and the inner surface 22 of lower and upper cross-member sidewall 20 will bear the power F that transmits through roll
1, this power produces a moment M with respect to the roof of crossbeam or the bight C between diapire inner surface 23 and the side wall inner surfaces 22
1, this moment loading is on beam side wall.Because place, described bight is easy to generate stress and concentrates, therefore, if roll-force is bigger, the bigger moment M of Chan Shenging then
1Cause the fracture of crossbeam easily.
In order to improve the force-bearing situation of crossbeam,, on basis embodiment illustrated in fig. 1, set up torque balance device 21 according to the utility model second embodiment.Shown in Figure 4 and 5, on the flange 35 of each side wall lower ends place formation of entablature, be formed with the through hole 25 that is used for equipped torque balance device 21 in addition; And on the flange 36 of each sidewall upper place formation of sill, also be formed with the through hole 26 that is used for equipped torque balance device 21 in addition.Torque balance device comprises a pull bar 28, and pull bar 28 is formed with external screw thread respectively at its place, axial two ends.
After the jockey that described upper and lower crossbeam and each column constitute by bar 8 and nut 9 is connected with each other, with pull bar 28 insert form on the upper and lower beam flange, in the mutual axially aligned through hole 25 and 26, then by spinning on pull bar 28 end external screw threads nut 29 and torque balance device is installed on the combined rack.By adjusting the power that screws of nut 29, can adjust the tension degree of each pull bar, thus will suitably big or small tensile force f
2Put on the flange 35 and 36 of upper and lower beam side wall.Power F
2Bight with respect to crossbeam produces a moment M
2, this moment loading is on the sidewall of crossbeam.Moment M
2With above-mentioned moment M
1Direction is opposite, offsets each other, has therefore improved the force-bearing situation of crossbeam.
Among the embodiment that addresses in the above, torque balance device and the 2 adjacent settings of corresponding column and along the outside that laterally is positioned at corresponding column 2 of crossbeam, but this is not to realize that the utility model purpose is necessary, they can be with corresponding column 2 adjacent settings and along the outside that vertically is positioned at corresponding column 2 of crossbeam, torque balance device can be arranged to the inboard that laterally or vertically is positioned at corresponding column 2 along crossbeam in addition, if its can with respect to the roof of crossbeam or the bight between diapire inner surface and the side wall inner surfaces produce act on the respective side walls, with above-mentioned moment M
1The moment that direction is opposite gets final product.
In the above-described embodiments, torque balance device is arranged between the lower and upper cross-member, but torque balance device also can be arranged between two opposed sidewalls of entablature or sill.Therefore, torque balance device of the present utility model is not limited to the application's description and illustrated particular form, anyly can produce above-mentioned moment M with respect to the bight of crossbeam
2Torque balance device all can adopt.
In addition, be similar to the nut 9 of first embodiment, the nut 29 of torque balance device also can replace with fluid cylinder 10 and hydraulic locking nut.
In conjunction with the accompanying drawings and embodiments the utility model is illustrated above, the insider should be appreciated that under the situation that does not deviate from the utility model spirit and scope, can make various improvement to the utility model.
