Description

Technical Field

[0001] The utility model relates to the technical field of roll changing equipment, in particular to a track-type roll changing system and a rolling mill system. Background Art

[0002] During the rolling process, the work and backup rolls of a rolling mill are subject to significant alternating loads and pressures. These alternating loads and pressures can easily cause cracks to form on the roll surfaces. Furthermore, during hot rolling, thermal stresses can further increase the risk of cracks on the roll surfaces. Failure to promptly replace cracks on work and backup rolls can lead to further expansion of the cracks, compromising product quality and potentially causing roll surface detachment and breakage.

[0003] Because work rolls and backup rolls are positioned differently, existing technology typically uses two independent roll-changing devices to change each roll, respectively, to improve roll-changing efficiency. However, in actual production, depending on the type, quality, and output of the rolled product, the work rolls of large hot rolling mills sometimes need to be replaced once a day or every three days. Backup rolls, on the other hand, are replaced approximately once a month or every month and a half.

[0004] Due to the difference in replacement frequency between work rolls and backup rolls, the roll-changing equipment used to replace backup rolls was used less frequently, leaving it idle for long periods of time and wasting a significant amount of equipment investment. Furthermore, the installation of two sets of roll-changing equipment increased the subsequent maintenance workload and costs. Utility Model Content

[0041] The technical solution of the utility model has the following significant beneficial effects:

[0042] When the track-type roll-changing system of the present invention is in use, the transverse roller device can drive the roll body to move along the transverse track mechanism for transporting or temporarily storing new and old roll bodies. The feed roller drive device can drive the rolling mill roll feed device to move along the roll-changing track mechanism. The roll-changing track mechanism can extend to the rolling mill, so that the feed roller drive device can push the roll body into the rolling mill or pull it out of the rolling mill, thereby completing the roll-changing operation. Alternatively, the roll body can be placed on the rolling mill roll feed device, and the feed roller drive device can push the rolling mill roll feed device to push the roll body into the rolling mill or pull it out of the rolling mill, thereby completing the roll-changing operation.

[0043] By connecting the roll changing track mechanism and the transverse moving track mechanism, interaction can be generated between the transverse moving roller device and the rolling mill roll feeding device and the roll feeding drive device, so that the roll body can be temporarily stored and transported between the transverse moving roller device and the rolling mill roll feeding device and the roll feeding drive device, thereby conveniently pushing in the new roll and pulling out the old roll to complete the roll changing operation.

[0044] The rail-type roll changing system of the utility model cooperates with the rail roll changing device through the transverse roller changing device. The support rolls and work rolls on the rolling mill can be replaced separately through the same roller feeding drive device, which significantly improves the utilization rate of the roller feeding drive device. During the roll changing operation, the roller feeding drive device transports the new roll body to the transverse roller device. The transverse roller device can temporarily store and transport the new and old roll bodies. The roller feeding drive device cooperates with the reciprocating motion along the roll changing track mechanism to complete the roll changing operation of pushing the new roll in and pulling the old roll out, greatly improving the roll changing efficiency of the rolling mill.

[0045] Furthermore, the transverse track mechanism also includes a track support structure. By arranging the track support structure between the first transverse track and the second transverse track, when the rotating transverse track connects the first transverse track and the second transverse track, the track support structure can support the rotating transverse track. By increasing the number of support points of the rotating transverse track, the track span of the rotating transverse track is reduced, and the deflection deformation of the rotating transverse track is reduced, so that the rotating transverse track can better connect the first transverse track and the second transverse track, thereby improving the operating stability of the transverse roller device on the rotating transverse track.

[0074] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0075] Please refer to Figures 1 to 15 In an embodiment of the utility model, a track-type roll changing system is provided, comprising: a transverse roll changing device 100, wherein the transverse roll changing device 100 comprises a transverse track mechanism 1 and a transverse roller device 2, wherein the transverse roller device 2 is movably arranged on the transverse track mechanism 1; a track roll changing device 200, wherein the track roll changing device 200 comprises a roll changing track mechanism 3, a rolling mill feed roller device 4 and a feed roller drive device 5, wherein the roll changing track mechanism 3 is arranged to intersect with the transverse track mechanism 1, the rolling mill feed roller device 4 and the feed roller drive device 5 are movably arranged on the roll changing track mechanism 3, the feed roller drive device 5 is connected to the rolling mill feed roller device 4, and the feed roller drive device 5 is used to push the rolling mill feed roller device 4 to move along the roll changing track mechanism 3.

[0076] Overall, when this rail-based roll-changing system is in use, the transverse idler device 2 drives the rolls along the transverse track mechanism 1, transporting or temporarily storing new and old rolls. The roll feed drive 5 drives the rolling mill roll feed device 4 along the roll-changing track mechanism 3. The roll-changing track mechanism 3 can extend to the rolling mill 500, allowing the roll feed drive 5 to push the rolls into or out of the rolling mill 500, completing the roll-changing operation. Alternatively, the rolls can be placed on the rolling mill roll feed device 4, which is then pushed by the roll feed drive 5 to move the rolls into or out of the rolling mill 500, completing the roll-changing operation. By connecting the roller changing track mechanism 3 and the transverse track mechanism 1, interaction can be generated between the transverse roller device 2 and the rolling mill roller feed device 4 and the roller feed drive device 5, so that the roller body can be temporarily stored and transported between the transverse roller device 2 and the rolling mill roller feed device 4 and the roller feed drive device 5, thereby conveniently pushing in the new roller and pulling out the old roller to complete the roller changing operation.

[0077] In the embodiments of the present invention, refer to Figure 1 and Figure 2 The roll changing track mechanism 3 includes a working roll changing track 31 and a supporting roll changing track 32 , and the working roll changing track 31 is arranged above the supporting roll changing track 32 at intervals.

[0078] The work roll changing track 31 can be used to transport the work rolls 91, and the backup roll changing track 32 can be used to transport the backup rolls 92. By arranging the work roll changing track 31 and the backup roll changing track 32 at intervals in the height direction, interference between the work roll changing track 31 and the backup roll changing track 32 during use can be avoided, thereby enabling the roll changing operation of the work rolls 91 and the backup rolls 92 in the rolling mill 500 to be performed using the roll changing track mechanism 3.

[0079] Specifically, the work roll changing track 31 can be arranged along the centerline of the mill entrance 500 to facilitate the transportation of the work rolls 91 in and out of the mill 500. The backup roll changing track 32 can be arranged parallel to and below the work roll changing track 31 to transport the backup rolls 92 in and out of the mill 500.

[0080] The working roll 91 may include a working roll body and an assembly provided on the working roll body, and the supporting roll 92 may include a supporting roll body and an assembly provided on the supporting roll body.

[0081] In an embodiment of the present invention, the working roll changing track 31 includes a turning track segment 33 and a fixed track segment 34 which are sequentially arranged, and the turning track segment 33 is controllably connected to the fixed track segment 34 .

[0082] Specifically, the fixed track section 34 can be fixedly arranged on the foundations on both sides of the rolling mill 500. The designer can set the foundation according to the use requirements, such as the ground foundation, which is not limited here.

[0083] The provision of the flip track section 33 creates space for the support roll 92 to enter and exit the support roll changing track 32. The flip track section 33 prevents interference between the work roll changing track 31 and the support roll changing track 32 during use, thereby enabling the track-type roll changing system to perform roll changing operations for the work roll 91 and the support roll 92, respectively.

[0084] When replacing the working roll 91, the flip track section 33 is connected to the fixed track section 34, so that the working roll 91 can be transported by the working roll changing track 31. When replacing the support roll 92, the flip track section 33 is flipped up and disconnected to form a space for the support roll 92 to enter and exit the support roll changing track 32, so that the new and old support rolls 92 can be lifted into or out of the support roll changing track 32 by the lifting equipment.

[0085] In the embodiments of the present invention, refer to Figure 4 and Figure 5The fixed track section 34 includes two fixed guide rails 37 arranged side by side, and the flipping track section 33 includes two flipping guide rails 35 arranged side by side. The flipping guide rails 35 are swingably arranged around the extension direction of the flipping track section 33. A flipping mechanism 36 is correspondingly provided on the flipping guide rails 35. The flipping mechanism 36 is used to push the flipping guide rails 35 to be swingably connected to the fixed guide rails 37.

[0086] By swinging the flip guide rails 35 about the extending direction of the flip track section 33, a space can be quickly and conveniently formed for the support roller 92 to enter and exit the support roller changing track 32. When replacing the support roller 92, the swing angle of the flip guide rails 35 is controlled so that the two flip guide rails 35 are separated from each other, thereby forming a space for the support roller 92 to enter and exit the support roller changing track 32. At this time, the support roller 92 can be hoisted into or out of the support roller changing track 32 using a lifting device.

[0087] In the embodiments of the present invention, refer to Figure 5 The flipping mechanism 36 includes a crank structure 361 and a flipping driving device 362 . One end of the crank structure 361 is connected to the flipping guide rail 35 , and the other end of the crank structure 361 is connected to the flipping driving device 362 .

[0088] Specifically, the tilting drive device 362 can be a telescopic device, such as a hydraulic cylinder or a pneumatic cylinder, without limitation. The telescopic rod of the telescopic device is connected to one end of the crank structure 361. The telescopic rod pushes the crank structure 361, causing the tilting guide rail 35 to tilt. The telescopic device can quickly and efficiently drive the tilting guide rail 35 to tilt or return.

[0089] Of course, the designer can also use an overhead crane to drive the flip guide rail 35 to flip, which is not limited here. Alternatively, the flip drive device 362 can also be a coaxial drive structure, that is, a rotary drive is set at the hinge point of the flip guide rail 35, and an electric motor or hydraulic motor is used to drive the flip guide rail 35 to rotate, thereby achieving the flip or fall operation.

[0090] In the embodiments of the present invention, refer to Figure 5 and Figure 6 The roller feeding drive device 5 includes a roller changing vehicle 51 , and the roller changing vehicle 51 is movably arranged on the supporting roller roller changing track 32 .

[0091] Specifically, the support roll changing rails 32 can be fixedly arranged on the foundations on both sides of the rolling mill 500. The roll changing vehicle 51 can push the roll body into or pull it out of the rolling mill 500 along the support roll changing rails 32, thereby completing the roll changing operation.

[0092] The roller changing vehicle 51 can be driven by a motor and a reducer drive gear. The roller changing vehicle 51 can also be provided with a matching power and cable retracting mechanism, such as a cable reel or an energy chain, for retracting and releasing the cable when the roller changing vehicle 51 is in operation.

[0093] In order to enable the roll changing car 51 to better pull the backup roll 92 or the work roll 91, a hook structure can be provided on the roll changing car 51, and this is not limited here. For example, two hooks of different heights can be provided at the front end of the roll changing car 51, with the upper hook being used for replacing the work roll 91 and the lower hook being used for replacing the backup roll 92.

[0094] Furthermore, a guide structure 8 may be provided between the roll-changing vehicle 51 and the support roller-changing track 32 to ensure smooth operation of the roll-changing vehicle 51, and an anti-rollover structure may be provided between the roll-changing vehicle 51 and the support roller-changing track 32, without limitation. Furthermore, an audible and visual alarm may be provided on the roll-changing vehicle 51 to issue an operating warning when the roll-changing vehicle 51 is in motion, thereby ensuring safe operation.

[0095] In the embodiments of the present invention, refer to Figure 2 The rolling mill roll feeding device 4 includes a roll changing transition car 41, which is movably arranged on the working roll changing track 31. The roll changing transition car 41 is detachably connected to the roll changing car 51, and the roll changing car 51 can push the roll changing transition car 41 to move along the working roll changing track 31.

[0096] Specifically, the roll-changing transition car 41 can be a plate-type platform trolley. A hook can be provided on both the end of the roll-changing transition car 41 that is closer to the rolling mill 500 and the end farther from the rolling mill 500. The hook on the side of the roll-changing transition car 41 farther from the rolling mill 500 can be coupled with the upper hook of the roll-changing car 51 to transmit power and implement the roll-changing operation.

[0097] When replacing the working rolls 91 , the roll-changing transition car 41 , which is close to the rolling mill 500 , is connected to the hooks on the operating side bearing seats of the new and old working rolls 91 through the hooks to drive the new and old working rolls 91 to move.

[0098] When the support rollers 92 are replaced, the end of the roll-changing transition car 41 close to the rolling mill 500 is connected to the hook on the roll-changing bracket 300 of the support roller 92 through the hook to drive the new and old support rollers 92 to move.

[0099] When the rolling mill 500 is under maintenance, the roll-changing transition car 41 close to the rolling mill 500 can also be combined with the hook on the maintenance platform through the hook, which is not limited here.

[0100] Of course, as an alternative embodiment to the hook, an independent support roll trolley 95 can be provided within the rolling mill 500 for transporting the support rolls 92. A hook can be provided on the support roll trolley 95, while no hook is provided on the bearing housing of the support roll 92. This is not a limitation. During roll changing operations, the bearing housing of the support roll 92 is seated on the support roll trolley 95, and the support roll 92 is transported by the support roll trolley 95. Rollers or slides can be provided beneath the support roll trolley 95, enabling the support roll trolley 95 to move on the support roll changing track 32, thereby transporting the support roll 92 in and out of the rolling mill 500.

[0101] In the embodiments of the present invention, refer to Figure 7 The roller changing transition vehicle 41 is detachably provided with a roller changing bracket 300 , and the roller changing bracket 300 is provided with at least one roller body storage station.

[0102] The roller-changing bracket 300 can be used to replace, repair, and maintain the support roller 92. Specifically, the roller-changing bracket 300 may have an operating side and a transmission side. A lower planar structure is provided below each of the operating and transmission sides. The lower planar structure can be placed on the plane of the bearing seat of the lower support roller 92, providing greater operational stability. The lower planar structure may have stoppers on both sides for mating with the bearing seat of the lower support roller 92, resulting in accurate positioning and reliable mating. Furthermore, a V-shaped keyway may be provided in the middle of the lower planar structure for mating with the V-shaped key on the bearing seat of the lower support roller 92, resulting in accurate positioning and reliable mating.

[0103] An upper planar structure is provided above the operating and transmission sides of the roller-changing bracket 300. The bearing seat of the upper support roller 92 is mounted on this upper planar structure, providing greater operational stability. A positioning pin is provided in the middle of the upper planar structure to engage with a pin hole in the bearing seat of the upper support roller 92, ensuring accurate positioning and reliable engagement.

[0104] In the embodiments of the present invention, refer to Figure 1 and Figure 2 The track-type roll changing system also includes a platform telescopic cover plate 7, one end of which is fixedly arranged, and the other end of which is connected to the roll changing vehicle 51. Driven by the roll changing vehicle 51, the platform telescopic cover plate 7 can telescopically cover the working roll changing track 31.

[0105] Specifically, a platform telescopic cover 7 can be set above the roller changing vehicle 51. The platform telescopic cover 7 can cover the closed operating passage plane of the roller changing track mechanism 3. Furthermore, a step ladder can be set on the roller changing vehicle 51 to facilitate operators to enter the roller changing vehicle 51.

[0106] In the embodiments of the present invention, refer to Figures 8 to 12 The transverse track mechanism 1 includes: a first transverse track 11 and a second transverse track 12 arranged at intervals; a rotating transverse track 13 arranged between the first transverse track 11 and the second transverse track 12, and the rotating transverse track 13 controllably connects the first transverse track 11 and the second transverse track 12; and a track support structure 14, which is arranged between the first transverse track 11 and the second transverse track 12, and when the rotating transverse track 13 is in a state of connecting the first transverse track 11 and the second transverse track 12, the track support structure 14 can support the rotating transverse track 13.

[0107] Specifically, the first and second transverse rails 11, 12 are spaced apart in the same direction, and the rotating transverse rail 13 controllably connects the first and second transverse rails 11, 12. When the rotating transverse rail 13 connects the first and second transverse rails 11, 12, the transverse roller assembly 2 can move along the transverse rail mechanism 1 to change rollers. When the rotating transverse rail 13 disconnects the first and second transverse rails 11, 12, the rotating transverse rail 13 clears a passage for the support rollers 92, thereby preventing interference between the support rollers 92 and the transverse rail mechanism 1.

[0108] By setting the track support structure 14 between the first transverse track 11 and the second transverse track 12, when the rotating transverse track 13 connects the first transverse track 11 and the second transverse track 12, the track support structure 14 can support the rotating transverse track 13. By increasing the number of support points of the rotating transverse track 13, the track span of the rotating transverse track 13 is reduced, thereby reducing the disturbance deformation of the rotating transverse track 13, so that the rotating transverse track 13 can better connect the first transverse track 11 and the second transverse track 12, thereby improving the operating stability of the transverse roller device 2 on the rotating transverse track 13.

[0109] In the embodiments of the present invention, refer to Figure 13 and Figure 14 The track support structure 14 includes a first support portion 141 arranged on the first transverse track 11, and a second support portion 142 arranged on the second transverse track 12. When the rotating transverse track 13 is in a state of connecting the first transverse track 11 and the second transverse track 12, the two ends of the rotating transverse track 13 are respectively overlapped on the first support portion 141 and the second support portion 142.

[0110] By means of a first support portion 141 arranged on the first transverse rail 11 and a second support portion 142 arranged on the second transverse rail 12, both ends of the rotating transverse rail 13 can be supported. On the one hand, the deformation of the rotating transverse rail 13 can be reduced. On the other hand, the rotating transverse rail 13 can be better connected with the first transverse rail 11 and the second transverse rail 12, thereby improving the stability of the transverse roller device 2 in moving between the first transverse rail 11, the rotating transverse rail 13 and the second transverse rail 12.

[0111] Specifically, a support surface can be provided on each of the first support portion 141 and the second support portion 142 , and the support surface can be provided in a horizontal direction. The support surface has a larger support range and can better support both ends of the rotating and transversely moving track 13 .

[0112] Furthermore, overlapping end surfaces that match the support surface can be set at both ends of the rotating and lateral movement track 13, so that the rotating and lateral movement track 13 can form a surface match with the support surface through the overlapping end surfaces, thereby improving the support performance.

[0113] In the embodiments of the present invention, refer to Figure 15 The track support structure 14 also includes at least one third support part 143 arranged between the first support part 141 and the second support part 142. When the rotating and transverse track 13 is in a state of connecting the first and second transverse tracks 11 and 12, the rotating and transverse track 13 is overlapped on the third support part 143.

[0114] By arranging at least one third support portion 143 between the first support portion 141 and the second support portion 142, the middle portion of the rotating and transverse track 13 can be supported by the third support portion 143, thereby reducing the track span of the rotating and transverse track 13 and further reducing the deflection deformation of the rotating and transverse track 13.

[0115] Specifically, a support that cooperates with the third support portion 143 can be provided on the rotating and traversing track 13. The support can be detachably mounted on the rotating and traversing track 13. When the support becomes worn, it can be removed and replaced. Of course, the support can also be fixedly mounted on the rotating and traversing device, which is not a limitation here.

[0116] In an embodiment of the present utility model, the supporting roller changing rail 32 is passed through the lower part of the rotating and transverse moving rail 13, and the supporting roller changing rail 32 includes two supporting roller changing guide rails 321 arranged in parallel. The third support part 143 is composed of the supporting roller changing guide rails 321. When the rotating and transverse moving rail 13 is in a state of connecting the first and second transverse moving rails 11 and 12, the rotating and transverse moving rail 13 is overlapped on the two supporting roller changing guide rails 321.

[0117] In the embodiments of the present invention, refer to Figure 2 When the rotating transverse track 13 is in a state of connecting the first transverse track 11 and the second transverse track 12 , the rotating transverse track 13 is arranged to intersect the supporting roller changing guide rail 321 perpendicularly.

[0118] Specifically, the backup roll changing track 32 can be arranged along the arrangement direction of the rolls in the rolling mill 500. Furthermore, by arranging the rotary and transverse track 13 perpendicularly to the backup roll changing track 32, it is easy to control the movement direction of the rolls, so that the rolls transported on the backup roll changing track 32 can be arranged in the same direction as the rolls in the rolling mill 500, facilitating the subsequent installation of the rolls on the rolling mill 500.

[0119] Furthermore, when the roller-changing vehicle 51 is transporting the support roller 92, interference with the support roller 92 can be avoided by controlling the rotational transverse track 13, thereby improving the convenience of transporting the support roller 92. Furthermore, when the support roller 92 is transported to the rotational transverse track 13, the support roller 92 can be transferred to the transverse roller device 2 by translation.

[0120] Among them, the supporting roller changing guide rail 321 can be set below the rotating transverse track 13. When the rotating transverse track 13 is in a state of connecting the first transverse track 11 and the second transverse track 12, the rotating transverse track 13 can be overlapped on the supporting roller changing guide rail 321 through the support.

[0121] In an embodiment of the present invention, the rotating and transverse track 13 includes two rotating and transverse guide rails 131 , wherein one rotating and transverse guide rail 131 is hinged to the first transverse track 11 , and the other rotating and transverse guide rail 131 is hinged to the second transverse track 12 .

[0122] By hingedly connecting the two rotating transverse guide rails 131 to the first transverse rail 11 and the second transverse rail 12 respectively, the stress generated during the installation and use of the rotating transverse guide rail 131 can be avoided from being concentrated on the transverse rail on the same side, thereby improving the use stability of the rotating transverse rail 13.

[0123] Of course, designers can also hinge the two rotating transverse guide rails 131 to the first transverse rail 11 or the second transverse rail 12 at the same time, and there is no limitation here.

[0124] In the embodiments of the present invention, refer to Figure 12 The transverse track mechanism 1 also includes a rotation drive device 132, which is connected to the rotating transverse track 13. The rotation drive device 132 is used to push the rotating transverse track 13 to controllably connect the first transverse track 11 and the second transverse track 12.

[0125] Specifically, the rotation drive device 132 may include a telescopic device, such as a hydraulic cylinder or a pneumatic cylinder, which drives the rotating and transverse guide rail 131 to rotate about a hinge point via a telescopic rod. Activating the telescopic device drives the rotating and transverse guide rail 131 to rotate about a hinge point, thereby connecting or disconnecting the rotating and transverse guide rail 131.

[0126] In an embodiment of the present utility model, the transverse roller device 2 includes a first transverse roller vehicle 21 and a second transverse roller vehicle 22 , and both the first transverse roller vehicle 21 and the second transverse roller vehicle 22 can move on the transverse track mechanism 1 .

[0127] Specifically, a roller table can be provided on each of the first and second transverse roller trolleys 21, 22, on which rollers can be placed for transportation. Of course, designers can also provide a roller replacement bracket 300 on the roller table as needed to place or replace rollers.

[0128] Furthermore, the first transverse roller trolley 21 is movably disposed on the first transverse rail 11, and the second transverse roller trolley 22 is movably disposed on the second transverse rail 12. When the rotating transverse rail 13 connects the first transverse rail 11 and the second transverse rail 12, the first transverse roller trolley 21 can move along the first transverse rail 11 and the rotating transverse rail 13 to the second transverse rail 12, and the second transverse roller trolley 22 can move along the second transverse rail 12 and the rotating transverse rail 13 to the first transverse rail 11. Designers can control the movement modes of the first transverse roller trolley 21 and the second transverse roller trolley 22 according to usage needs, and no specific restrictions are imposed here.

[0129] In the embodiments of the present invention, refer to Figure 12 The transverse roller changing device 100 also includes a guide structure 8, which includes a first guide slide 81 arranged on the first transverse roller trolley 21, a second guide slide 82 arranged on the second transverse roller trolley 22, and a transverse guide slide 83 arranged on the transverse track mechanism 1. The first transverse roller trolley 21 and the transverse track mechanism 1 are slidably matched with each other through the first guide slide 81 and the transverse guide slide 83, and the second transverse roller trolley 22 and the transverse track mechanism 1 are slidably matched with each other through the second guide slide 82 and the transverse guide slide 83.

[0130] Specifically, the first guide slide 81 may be provided at the lower portion of the first transverse roller trolley 21. The first transverse roller trolley 21 slidably cooperates with a transverse guide slide 83 provided on the transverse track mechanism 1 via the first guide slide 81, so that the first transverse roller trolley 21 can move along the setting direction of the transverse track mechanism 1. The second guide slide 82 may be provided at the lower portion of the second transverse roller trolley 22. The second transverse roller trolley 22 slidably cooperates with a transverse guide slide 83 provided on the transverse track mechanism 1 via the second guide slide 82, so that the second transverse roller trolley 22 can also move along the setting direction of the transverse track mechanism 1.

[0131] Of course, as another replaceable setting method of the guide structure 8, a fixed track platform 400 can also be set. The fixed track platform 400 is set along the direction of the transverse track mechanism 1 and is set above the transverse track mechanism 1. The transverse guide skateboard 83 can be set on the fixed track platform 400, and the first transverse roller car 21 is connected to the transverse guide skateboard 83 on the fixed track platform 400 through the first guide skateboard 81, and the second transverse roller car 22 is connected to the transverse guide skateboard 83 on the fixed track platform 400 through the second guide skateboard 82.

[0132] The fixed track platform 400 can be arranged between the rolling mill 500 and the transverse track mechanism 1. A platform track can be provided on the fixed track platform to connect the rolling mill 500 with the transverse roller device 2 on the transverse track mechanism 1. Furthermore, the fixed track platform can be detachably provided to prevent interference with the roller body entering and exiting the rolling mill 500.

[0133] Of course, designers can also set the transverse guide slide 83 at other positions or structures, which is not limited here.

[0134] By cooperating with the first guide slide 81, the second guide slide 82 and the transverse guide slide 83, the first transverse roller trolley 21 and the second transverse roller trolley 22 can move along the preset direction, which also improves the stability of the first transverse roller trolley 21 and the second transverse roller trolley 22 moving along the transverse track mechanism 1.

[0135] In the embodiments of the present invention, refer to Figure 10 The transverse roller changing device 100 also includes a first transverse driving device 23 and a second transverse driving device 24. The first transverse driving device 23 is connected to the first transverse roller vehicle 21, and the second transverse driving device 24 is connected to the second transverse roller vehicle 22.

[0136] Specifically, the first transverse driving device 23 and the second transverse driving device 24 can both adopt telescopic devices, such as hydraulic cylinders or air cylinders. The telescopic devices are connected to the corresponding first transverse roller trolley 21 and second transverse roller trolley 22 through telescopic rods, and are used to push the first transverse roller trolley 21 and the second transverse roller trolley 22 to move along the transverse track mechanism 1.

[0137] In the embodiments of the present invention, refer to Figure 9 The first transverse roller vehicle 21 is provided with a first connecting portion 25, and the second transverse roller vehicle 22 is provided with a second connecting portion 26. The first connecting portion 25 and the second connecting portion 26 are detachably connected.

[0138] Specifically, the first connecting portion 25 and the second connecting portion 26 can be detachably connected by bolts. Of course, the first connecting portion 25 and the second connecting portion 26 can also be detachably connected by snap fasteners, which is not limited here.

[0139] By connecting the first transverse roller trolley 21 with the second transverse roller trolley 22, the first transverse roller trolley 21 and the second transverse roller trolley 22 can move synchronously, so that only the first transverse roller trolley 21 or the second transverse roller trolley 22 needs to be pushed to push the first transverse roller trolley 21 and the second transverse roller trolley 22 to move synchronously along the transverse rail mechanism 1 for placing or transporting the roller body.

[0140] In the embodiments of the present invention, refer to Figure 8 The transverse roller changing device 100 also includes a transverse track cover structure 6, and the transverse track cover structure 6 includes a first telescopic cover 61 and a second telescopic cover 62; one end of the first telescopic cover 61 is fixedly arranged, and the other end of the first telescopic cover 61 is connected to the first transverse roller trolley 21. Driven by the first transverse roller trolley 21, the first telescopic cover 61 can telescopically cover the first transverse track 11; one end of the second telescopic cover 62 is fixedly arranged, and the other end of the second telescopic cover 62 is connected to the second transverse roller trolley 22. Driven by the second transverse roller trolley 22, the second telescopic cover 62 can telescopically cover the second transverse track 12.

[0141] Specifically, one end of the first telescopic cover plate 61 is fixedly arranged at an end of the first transverse rail 11 away from the second transverse rail 12, and the other end of the first telescopic cover plate 61 is connected to the first transverse roller trolley 21, so that when the first transverse roller trolley 21 moves along the transverse rail mechanism 1, the first transverse roller trolley 21 can drive the first telescopic cover plate 61 to cover the first transverse rail 11. One end of the second telescopic cover plate 62 is fixedly arranged at an end of the second transverse rail 12 away from the first transverse rail 11, and the other end of the second telescopic cover plate 62 is connected to the second transverse roller trolley 22, so that when the second transverse roller trolley 22 moves along the transverse rail mechanism 1, the second transverse roller trolley 22 can drive the second telescopic cover plate 62 to cover the second transverse rail 12.

[0142] The first telescopic cover plate 61 and the second telescopic cover plate 62 can protect the first transverse rail 11 and the second transverse rail 12, thereby preventing foreign matter from entering the transverse rail mechanism 1 and affecting the operational stability of the first transverse roller trolley 21 and the second transverse roller trolley 22. Furthermore, the first telescopic cover plate 61 and the second telescopic cover plate 62 can also be used as an operating platform, which is not limited here.

[0143] The present invention also provides a rolling mill system in accordance with the present invention. Figure 1 and Figure 2 The rolling mill 500 includes the track-type roll-changing system described in the aforementioned embodiment, and a transition track structure. The track-type roll-changing system is connected to the rolling mill 500 via the transition track structure. The specific structure, operating principle, and beneficial effects of the track-type roll-changing system are the same as those described in the aforementioned embodiment and are not further described here. The rolling mill system, utilizing the track-type roll-changing system, can improve roll-changing efficiency and utilization of roll-changing equipment.

[0145] The provision of the working roll track 93 inside the machine facilitates the working roll 91 to enter and exit the rolling mill 500, thereby improving the roll changing efficiency of the working roll 91. The provision of the backup roll track 94 inside the machine facilitates the backup roll 92 to enter and exit the rolling mill 500, thereby improving the roll changing efficiency of the backup roll 92.

[0146] Furthermore, the frame 9 is configured to be liftable. A hydraulic device can be used to drive the frame 9 up and down, facilitating removal of the support rolls 92 or the work rolls 91 from the frame 9. Designers can adjust the height of the frame 9 to facilitate roll removal based on the installation method of the support rolls 92 and the work rolls 91, and this is not a specific limitation.

[0147] Of course, designers can also use other lifting structures to drive the frame 9 to move up and down, and there is no limitation here.
