In the present specification, the illustrative description of the above terms does not necessarily refer to the same embodiment or implementation. Furthermore, the specific features, structures, materials or characteristics described can be combined in any one or more embodiments or implementations in a suitable manner.

[0032] Referring to Figure 1 In the related art, the vertical roll mill stand is composed of two pieces of stand, i.e. the upper cross beam 16 and the lower cross beam 17, and is fixed together through the positioning ring 18, has a long processing cycle and high production cost, and needs to first lift the shaft through a special lifting tool and then replace the roller when replacing the roller. In order to solve the technical problem, with reference to Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 , the embodiment of the present application proposes a combined frame type vertical roll mill stand, which comprises a driving side fixed column 1, an operating side fixed column 2, an upper connecting beam 3, a middle connecting beam 4, a lower connecting beam 5 and a pull rod 6. The driving side fixed column 1 and the operating side fixed column 2 are fixedly connected through the upper connecting beam 3, the middle connecting beam 4 and the lower connecting beam 5 respectively. Two groups of the upper connecting beam 3, the middle connecting beam 4, the lower connecting beam 5 and the pull rod 6 are symmetrically distributed on the two sides of the driving side fixed column 1 and the operating side fixed column 2. Thus, the part between the two forms a mounting window 14 for mounting the roller (and other components such as the hydraulic cylinder).

[0033] The pull rod 6 comprises a first pull rod 61 and a second pull rod 62, and each side of the upper connecting beam 3 and the middle connecting beam 4 is fixedly connected by the second pull rod 62, and each side of the middle connecting beam 4 and the lower connecting beam 5 is fixedly connected by the first pull rod 61. The transmission side fixed column 1 and the operation side fixed column 2 are sequentially provided with an AWC hydraulic cylinder mounting hole 10, a balance cylinder mounting hole 11 and a main shaft mounting hole 12 from top to bottom, and the top of the upper connecting beam 3 on both sides is detachably provided with a guide pressing plate 7 through a detachable fixing part 8. The guide pressing plate 7 and the upper connecting beam 3 on each side form a sliding guide groove 22, and the sliding guide grooves 22 on both sides are used for slidingly connecting the roll bearing seat.

[0034] Specifically, the transmission side fixed column 1 and the operation side fixed column 2 are arranged in parallel. Before actual assembly, the transmission side fixed column 1 and the operation side fixed column 2 are fixed on the factory foundation respectively, and the transmission side fixed column 1 and the operation side fixed column 2 constitute the columns of the rolling mill stand. The upper connecting beam 3, the upper connecting beam 3 and the middle connecting beam 4 are sequentially distributed along the columns from top to bottom and are fixed on both sides of the columns. The transmission side fixed column 1, the operation side fixed column 2, the upper connecting beam 3, the middle connecting beam 4 and the lower connecting beam 5 constitute the overall frame of the rolling mill stand. Similarly, the two columns are sequentially provided with the AWC hydraulic cylinder mounting hole 10, the balance cylinder mounting hole 11 and the main shaft mounting hole 12 from top to bottom. The AWC hydraulic cylinder mounting hole 10 is used for mounting the AWC hydraulic cylinder, the balance cylinder mounting hole 11 is used for mounting the balance cylinder, and the main shaft mounting hole 12 is used for mounting the main shaft. The opening degree of the roll (on the roll bearing seat) is adjusted and the roll is reset under the action of the AWC hydraulic cylinder and the balance cylinder. The power of the external motor is transmitted to the roll through the main shaft. The vertical roll is rotatably installed between the roll bearing seats, and the roll bearing seat is slidably installed on the roll stand. Exemplarily, a roller is rotatably installed on the roll bearing seat, and the roller is embedded in the sliding guide groove 22, so as to realize the sliding connection between the roll bearing seat and the rolling mill stand.

[0035] The embodiment is characterized in that the rolling mill stand is composed of the transmission side fixed column 1, the operation side fixed column 2, the upper connecting beam 3, the middle connecting beam 4 and the lower connecting beam 5, the frame is used as the overall stress frame during the rolling of the steel material, the upper connecting beam 3, the middle connecting beam 4 and the lower connecting beam 5 are used as the connecting beams of the rolling mill stand, the transmission side fixed column 1 and the operation side fixed column 2 are tightly connected, the strength and the rigidity of the overall frame are improved, further, the upper connecting beam 3 and the middle connecting beam 4 on each side are fixedly connected through the second pull rod 62, the middle connecting beam 4 and the lower connecting beam 5 on each side are fixedly connected through the first pull rod 61, the first pull rod 61 and the second pull rod 62 can be fixed through, for example, bolts or pins, the rolling force received by the roller stand can be evenly transmitted to the columns and the connecting beams, thereby, the rigidity, the strength and the stability of the overall frame are further improved, under the overall frame, the AWC hydraulic cylinder mounting hole 10, the balance cylinder mounting hole 11 and the main spindle mounting hole 12 distributed along the columns from top to bottom can also ensure the smooth operation of the hydraulic cylinder or the spindle after installation, thereby, the roller stand can be directly assembled into the overall frame by the plurality of cross beams and the columns, and the overall frame and the reinforcing structure (the pull rod 6) of the overall frame are further assembled, due to the simple structure of each part, the processing difficulty of the roller stand is reduced, and the production and transportation costs are effectively reduced, further, the sliding guide grooves 22 on the two sides are used for slidingly connecting the roller bearing seat, the guide pressing plate 7 composed of the sliding guide grooves 22 is installed on the top of the upper connecting beam 3 through the detachable fixing piece 8, the detachable fixing piece 8 is detachable, when the roller is replaced, the overall frame does not need to be disassembled, only the removal of the detachable fixing piece 8 is needed to remove the limitation of the guide pressing plate 7 on the roller bearing seat, and then the roller (and the roller bearing seat as a whole) can be directly lifted out or lifted in from above the upper connecting beam 3 (that is, the top of the installation window 14), so that the roller can be quickly replaced, and the maintenance time is reduced. The present application adopts the lower transmission roller, does not need to remove the main spindle, and directly lifts the roller.

[0036] The present application divides the rolling mill stand into a plurality of independent but interconnected parts, such as columns, connecting beams and pull rods 6, which can be manufactured, processed and transported separately, and then assembled on site, greatly improving manufacturing efficiency and flexibility, adopting the design of upper, middle and lower three-layer connecting beams, and the pull rod 6 further enhances the overall stability of the stand, through reasonable layout and adjustment, the stress condition of the stand can be optimized, deformation and vibration can be reduced, and quick roller replacement can be realized, in summary, the combined frame type roller stand created by the present application overcomes the problems of difficult processing, high cost and difficult roller replacement of the traditional stand through a series of innovative designs, and provides a more efficient, economical and reliable solution for the design and manufacture of the roller stand.

[0037] Referring to Figure 3 As an optional embodiment of the present application, a plurality of first pull rods 61 and a plurality of second pull rods 62 are arranged on each side, and the first pull rods 61 and the second pull rods 62 are arranged in a telescopic manner.

[0038] Specifically, the first pull rod 61 and the second pull rod 62 are not essentially different in structure (both are components of the pull rod 6), and generally only differ in size. The two ends of the pull rod 6 are fixed to the corresponding connecting beams through a connecting pin 15. The two ends of the first pull rod 61 are fixed to the middle connecting beam 4 and the lower connecting beam 5, and the two ends of the second pull rod 62 are fixed to the upper connecting beam 3 and the middle connecting beam 4. The connecting beams are fixed with corresponding ear seats, the connecting pin 15 fixes the end of the pull rod 6 to the ear seat, and the rod body of the pull rod 6 is segmented. For example Figure 3 The middle pull rod 6 is divided into two segments in the middle, the opposite parts of the two segments are provided with connecting ear seats, and the connecting ear seats are connected through bolts. By adding or removing shims 19 between the connecting ear seats, the length of the pull rod 6 can be adjusted.

[0039] The pull rod 6 is a component of the overall frame for stabilizing the rolling mill stand, and plays a role in stabilizing and supporting the upper connecting beam 3 and the middle connecting beam 4 on each side, the middle connecting beam 4 and the lower connecting beam 5 on each side. After the upper connecting beam 3, the middle connecting beam 4 and the lower connecting beam 5 are fixed to the two sides of the drive side fixed column 1 and the operation side fixed column 2 through bolts, there may be a phenomenon of easy loosening and deformation. Through the telescopic arrangement of the pull rod 6, the overall frame can be reinforced by adjusting the length under the conditions of loosening and deformation.

[0040] As shown in Figure 4 As an optional embodiment of the present application, the first pull rod 61 on each side is arranged alternately inclined and vertically between the middle connecting beam 4 and the lower connecting beam 5, and the main shaft mounting hole 12 is arranged centrally (to ensure the center) and close to the middle connecting beam 4 or the lower connecting beam 5 (to ensure the strength and rigidity).

[0041] Preferably, the mounting holes on the two columns are arranged correspondingly. The AWC hydraulic cylinder mounting hole 10 is provided with two pairs (four) of holes. The upper two holes (one is arranged along the positive direction of the X axis and the other is arranged along the negative direction of the X axis) are arranged between the upper connecting beams 3 on both sides, and the lower two holes are arranged between the middle connecting beams 4 on both sides. The two balance cylinder mounting holes 11 are arranged on the drive side fixed column 1 and the operation side fixed column 2 and located between the middle connecting beam 4 and the lower connecting beam 5. In this way, the hydraulic cylinder or the main shaft can be stably installed.

[0042] Specifically, a plurality of first pull rods 61 are arranged between the middle connecting beam 4 and the lower connecting beam 5 on each side, and the first pull rod 61 is arranged Figure 4The alternate arrangement of the inclined and vertical first pull rods 61 can form multi-directional connecting supports between the middle connecting beams 4 and the lower connecting beams 5 in the middle of each side, which can adapt to the forces in different directions during rolling, so that the middle connecting beams 4 and the lower connecting beams 5 remain stably connected without deformation. In addition, the first pull rods 61 are arranged in an extendable manner, so that each first pull rod 61 can stably support the middle connecting beams 4 and the lower connecting beams 5 under the condition of alternate arrangement, so that the relative positions of the middle connecting beams 4 and the lower connecting beams 5 on the transmission side fixed column 1 and the operation side fixed column 2 are not deformed, thereby ensuring the stability of the overall frame of the rolling mill stand, especially for the part close to the bottom, where the lower connecting beams 5 (the main shaft is preferably centrally installed and close to the middle connecting beams 4 or the lower connecting beams 5, and the main shaft mounting hole 12 is close to the lower connecting beams 5 in the middle of the main shaft mounting hole 12) are used to install the main shaft for transmitting the power of the rolling mill, which has higher requirements for strength and rigidity. Therefore, the alternate arrangement of the inclined and vertical first pull rods 61 can better meet such requirements, thereby ensuring the stable transmission of the power of the rolling mill during rolling. Figure 2

[0043] As shown in Figure 7 and Figure 8 As an optional embodiment of the present application, the guide pressing plate 7 includes a first guide part 71 and a second guide part 72, the first guide part 71 is attached to the top surface of the upper connecting beam 3, and the second guide part 72 is fixed to the top of the first guide part 71. The first guide part 71, the second guide part 72 and the upper connecting beam 3 form the sliding guide groove 22, and the detachable fixing part 8 is connected to the upper connecting beam 3 after penetrating the first guide part 71 and the second guide part 72.

[0044] Specifically, by setting the guide pressing plate 7 as the first guide part 71 and the second guide part 72, the first guide part 71 can support the second guide part 72, so that the second guide part 72 can be supported to form the sliding guide groove 22 with the first guide part 71 and the upper connecting beam 3. Correspondingly, the detachable fixing part 8 penetrates the first guide part 71 and the second guide part 72 to detachably fix the guide pressing plate 7 on the upper connecting beam 3. Since the detachable fixing part 8 penetrates the first guide part 71 and the second guide part 72, multiple contact fixings are achieved, which improves the fixing effect.

[0045] As shown in Figure 7 ​As shown, in an optional embodiment of the present invention, the first guide portion 71 is folded, and the folded first guide portion 71 includes a fixedly connected fitting portion and a side portion. The fitting portion of the first guide portion 71 fits against the upper connecting beam 3, and the side portion of the first guide portion 71 is fixedly connected to the second guide portion 72. A reinforcing rib is also provided between the first guide portion 71 and the second guide portion 72. The detachable fastener 8 passes through the fitting portion of the first guide portion 71 and the second guide portion 72.

[0046] Specifically, the first guide portion 71 of the folded type is right-angled (the side and the fitting portion are perpendicular to each other). The fitting portion fits against the surface of the upper connecting beam 3, and the side portion is used to fix the second guide portion 72. Along the length direction of the first guide portion 71, the first guide portion 71 and the middle of the second guide portion 72 are fixed. The reinforcing rib extends along the bottom of the second guide portion 72 to the surface of the first guide portion 71, and is fixedly connected to the side, the fitting portion and the second guide portion 72 of the first guide portion 71 respectively. This improves the mechanical properties of the guide pressure plate 7, so that the guide pressure plate 7 and the upper connecting beam 3 cooperate to firmly confine the roller of the roll bearing in the sliding guide groove 22, thus completing the roll bearing seat ( Figure 7 (Not shown in the diagram) and the sliding connection between the rolling mill stand; it should be noted that a sliding guide groove 22 is formed between the side wall of the first guide part 71 (the side part and the side edge of the fitting part), the bottom of the second guide part 72 and the surface of the upper connecting beam 3. Generally, a concave groove is provided on the surface of the upper connecting beam 3 and the surface opposite to the bottom of the second guide part 72 to limit the roller of the roll bearing seat within it, thereby forming a sliding connection between the roll bearing seat and the rolling mill stand, so as to realize the adjustment of the roll opening degree and the roll pullback reset under the action of the AWC hydraulic cylinder and the balance cylinder (through the roll bearing seat).

[0047] like Figure 7 , Figure 8 As shown, in an optional embodiment of the present invention, the detachable fastener 8 includes a positioning pin 81, a wedge hole 82, a wedge 83, and a washer 84. The bottom end of the positioning pin 81 is fixedly connected to the upper connecting beam 3. The first guide portion 71 and the second guide portion 72 are integrally provided with through holes that are clearance-fitted with the positioning pin 81. The top end of the positioning pin 81 protrudes from the through hole and is fitted with the washer 84. The positioning pin 81 has the wedge hole 82. The wedge 83 is inserted into the wedge hole 82 and presses the washer 84 against the surface of the second guide portion 72.

[0048] Specifically, when fixing the guide pressing plate 7, the first guide part 71 and the second guide part 72 are arranged opposite to each other on the side of the upper connecting beam 3 forming the groove, and then the through hole is aligned with the positioning pin 81 and inserted, so that the abutting part of the first guide part 71 is abutted to the surface of the upper connecting beam 3, and then the washer 84 is sleeved outside the positioning pin 81, and finally the wedge 83 is inserted from the wedge hole 82 until the washer 84 is pressed on the surface of the guide pressing plate 7, and part of the wedge hole 82 needs to be exposed to the through hole, so that the wedge 83 can press the washer 84, and the washer 84 is abutted to the surface of the second guide part 72. It should be noted that the wedge 83 can also be provided with a limiting hole, and a plug pin can be inserted into the limiting hole to prevent the wedge 83 from falling off. When disassembling the guide pressing plate 7, the process is opposite to the installation process, which will not be described here. Compared with the bolt connection, the above connection can realize quick disassembly and assembly, that is, it provides conditions for quickly replacing the roller without disassembling the overall frame.

[0049] As shown in Figure 4 , Figure 6 , Figure 7 and Figure 9 , as an optional embodiment of the present application, a guide assembly is further arranged between the upper connecting beam 3 and the intermediate connecting beam 4, the guide assembly includes an entry and exit guide plate 9, a lower guide roller 20 and an upper guide plate 21 arranged correspondingly, the upper guide plate 21 is detachably arranged between the upper connecting beams 3 on both sides through the detachable fixing part 8, the lower guide roller 20 is rotatably arranged between the intermediate connecting beams 4 on both sides, and the entry and exit guide plate 9 is fixed to the upper connecting beams 3 on both sides and located on the opposite outer side of the upper guide plate 21.

[0050] Specifically, the upper guide plate 21 and the lower guide roller 20 are respectively arranged above and below the inside of the rolling mill stand, for restraining the upper and lower positions of the rolled steel plate, the lower guide roller 20 also plays a guiding role for the rolled steel plate, the lower guide roller 20 is rotatably arranged and plays a guiding role for the rolled steel plate from the entry side to the exit side (in the direction of the Y axis), and is arranged between the intermediate connecting beams 4 on both sides through a seat body, the upper guide plate 21 is arranged fixed between the upper connecting beams 3 on both sides, the upper guide plate 21 is in the shape of “U”, and the two ends of the upper guide plate 21 are also fixed through the detachable fixing part 8, the bottom of the “U” shape is opposite to the lower guide roller 20 and mainly plays a role of restraining the rolled steel plate, for the entry and exit guide plate 9, it is arranged on the entry side and the exit side respectively and located on the bottom of the upper connecting beam 3, the upper guide plate 21 is arranged at the middle position, and the entry and exit guide plate 9 is arranged on the opposite outer side of the upper guide plate 21, that is, fixed at the entry and exit of the rolling mill stand, for preventing the whole rolling mill stand from being impacted by the rolled steel plate, thereby playing a role of protecting the whole rolling mill stand (especially the upper connecting beam 3).

[0051] It should be noted that since the detachable fastener 8 is detachable, its principle for installing the upper guide plate 21 and the guide pressure plate 7 is the same. Both are installed on the upper connecting beam 3. Referring to the description of installing the guide pressure plate 7 in the previous embodiment, when installing the upper guide plate 21, the upper guide plate 21 can be directly replaced with the guide pressure plate 7. The size of the detachable fastener 8 used to install the upper guide plate 21 is generally larger than the size of the detachable fastener 8 used to install the guide pressure plate 7. When changing the roll, the guide pressure plate 7 needs to be removed, and the upper guide plate 21 should also be removed at the same time. It is not necessary to disassemble the overall frame formed by the columns (drive-side fixed column 1 and operation-side fixed column 2) and the connecting beams (upper connecting beam 3, middle connecting beam 4 and lower connecting beam 5) of the mill stand, so that the roll can be changed quickly.

[0052] like Figure 5 As shown, in an optional embodiment of the present invention, along the extraction direction of the AWC hydraulic cylinder on the AWC hydraulic cylinder mounting hole 10, the side walls of the transmission side fixed column 1 and the operation side fixed column 2 are respectively equipped with disassembly and assembly auxiliary brackets 13.

[0053] Specifically, the direction of extraction is also the direction of disassembly and assembly, along... Figure 5 The direction of the X-axis, whether positive or negative, can be selected according to actual needs. The disassembly and assembly auxiliary bracket 13 is installed on at least one side of the transmission-side fixed column 1 and the operation-side fixed column 2.
