When the roller set is maintained and replaced in the later period, each upright post does not need to be lifted independently for dismounting, and the labor degree is greatly reduced.
In actual use, through erecting stand 13, through two setting elements one 5 socket joint on stand 13 and with base 2 butt, stand 13 will remain vertical state throughout afterwards, can greatly reduce the load of round pin axle 6 department through two setting elements one 5 on stand 13, prevent that this department from appearing warping, hoist frame entablature 10 to the top of stand 13 afterwards to through a fixing piece 9 with frame entablature 9 and stand 13 fixed mounting as an organic whole.
Example 2:
as shown in fig. 1 to 2, a further improvement is provided on the basis of embodiment 1, wherein a first positioning groove is formed on an upper surface of the base 2, and the first positioning groove is adapted to a first positioning element 5. Install through positioning groove one on the base 2 and setting element 5, guarantee the stability of setting element 5 for setting element 5 only bears vertical load, and the vertical state of stand 13 when greatly guaranteeing the later stage to change the maintenance to the roller set, the dismouting effect of the device of being convenient for.
Example 3:
as shown in fig. 1 to 2, a further improvement scheme is provided on the basis of embodiment 2, two opposite side walls of the upright column 13 are respectively provided with a second fixing member 7, the second fixing member 7 is preferably a bolt, the upright column 13 is detachably connected with a second positioning plate 4 through the second fixing member 7, one side of the second positioning plate 4, which is opposite to the base 2, is provided with a second positioning groove, and the second positioning groove is adapted to the first positioning member 5. Through being stand 13 under the vertical condition, utilize locating plate 4 and base 2 butt on it, can further eliminate the load of round pin axle 6 to shift to base 2 and stand 13 completely on, utilize positioning groove two to carry out position with setting element 5 and prescribe a limit to, can also guarantee the area of contact of locating plate 4 and base 2 simultaneously, guarantee its stability and reliability.
Example 5:
as shown in fig. 1 to fig. 2, based on embodiment 4, in a further improved manner, a third fixing member 8 is mounted on the positioning plate 4, the third fixing member 8 is preferably a bolt, and the positioning plate 4 is detachably mounted to the base 2 through the third fixing member 8. The positioning plate 4 and the base 2 are installed through bolts, so that the upright post 13 and the base 2 form a whole body
Example 6:
as shown in fig. 1 to 2, based on the embodiment 5, a third positioning groove is formed on one side of the upright column 13 opposite to the upper frame beam 10, and a second positioning element 12 is installed inside the third positioning groove located on the upright column 13 and the upper frame beam 10 and opposite to each other.
Example 7:
as shown in fig. 1 to fig. 2, based on the embodiment 6, a limit plate 1 is fixedly installed on one side of the upright column 13 relative to the area between the upper frame beam 10 and the base 2, and when the limit plate 1 contacts with the upper surface of the base 2.
In this embodiment, it is further preferable that a hanging ring 11 is mounted on an upper surface of the upper frame beam 10. The hoisting of the upper frame beam 10 and the fixed installation of the upper frame beam and the upright post 13 are facilitated through the hoisting ring 11.
When the high-pressure roller mill works, the movable roller group and the fixed roller group respectively apply transversely outward great acting force on the stand columns, and the stand columns 13 transmit the acting force to the whole frame, so that the whole stress is balanced and stable. Wherein the base 2 is stressed as follows: the upright column 13 firstly transmits most acting force to the base 2 through the first positioning part 5, then transmits a small acting force to the positioning plate 4 through the second fixing part 7, and then the positioning plate 4 transmits the acting force to the base 2 through the first positioning part 5. The upper frame beam 10 directly receives the acting force transmitted by the upright post 13 through the positioning piece two 12 and the fixing piece one 9. Through the structural design, the whole force transmission and stress state of the frame are kept better, and the pin shaft 6 of the hinge structure is basically free from acting force.
When the roller set is maintained and replaced, firstly, a second positioning piece 7 and a first fixing piece 9 between an upper beam 10 and a vertical column 13 of the rack are removed, meanwhile, an ejector rod of the feeding device is also removed, a lifting ring 11 is installed on the upper beam 10 of the rack, and the upper beam 10 of the rack and the feeding device are lifted upwards by a small distance by using a lifting device. The connecting members of the uprights 13 to the sets of rollers are then removed. And then the second fixing piece 7 and the third fixing piece 8 on the positioning plates 4 on the two sides of the single upright column 13 are removed, and then the positioning plates 4 and the first positioning pieces 5 on the single upright column 13 are removed. The stable upright column 13 needs to be supported in the dismantling process, and the flat upright column 13 is slowly rotated after the dismantling is finished, as shown in fig. 2. According to the method, the second fixing piece 7, the third fixing piece 8, the positioning plate 4 and the first positioning piece 5 on the remaining 3 stand columns 13 are respectively removed and are rotated and laid flat. And finally, respectively pushing the movable and fixed roller sets outwards along the slide rails 3, and carrying away by using a roller changing trolley to finish the roller set dismantling.
And then, mounting the roller sets, and respectively transporting the movable and fixed roller sets from two sides of the rack by using roller changing trolleys and pushing the movable and fixed roller sets to a target position along the slide rails 3. The upright post 13 is rotated and erected, and the fixing piece II 7, the fixing piece III 8, the positioning plate 4 and the positioning piece I5 are respectively installed. And integrally putting down the upper frame beam 10 and the feeding device, and using the second positioning piece 12 and the first fixing piece 9 for mounting and limiting. And after the ejector rod of the feeding device is installed, the roller set is maintained and replaced. Wherein, only the installation of the upper beam 10 of the frame needs to be repositioned in the installation process, and the whole installation and positioning process of the frame is obviously simplified. The hinge pin 6 does not bear heavy load when the high-pressure roller mill works, and compared with a completely hinged rack structure, the structure is stable in bearing, and the hinge pin 6 cannot deform and is difficult to disassemble and assemble.
Example 8: a high pressure roller mill comprising the frame structure according to embodiment 7.
The above description is only a preferred embodiment of the present invention, but the scope of the present invention is not limited thereto. The substitution may be of partial structures, devices, method steps, or may be a complete solution. The technical solution and the practical idea of the present invention should be covered by the protection scope of the present invention.
