Description

Technical Field

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

[0002] The working rolls and backup rolls of the rolling mill need to withstand huge alternating load pressure during the rolling process. Under the influence of alternating load pressure, cracks are easily generated on the roll surfaces of the working rolls and backup rolls. When the rolling mill is hot-rolled, the roll surface will also be affected by thermal stress, making it more likely to crack. If the working rolls and backup rolls are not replaced in time after crack defects occur on the working rolls and backup rolls, the cracks on the roll body will further expand, thereby affecting the quality of the rolled product and even causing the roll surface to detach and the roll to break.

[0003] Since the working rolls and backup rolls are set at different positions, in order to improve the efficiency of roll changing, two sets of independent roll changing devices are usually used in the prior art to change the working rolls and backup rolls respectively. However, in the actual production process, depending on the type, quality and output of the rolled products, the working rolls of large hot rolling mills sometimes need to be replaced once a day, and sometimes once every three days. The backup rolls are replaced about once a month or one and a half months.

[0004] Due to the difference in replacement frequency between the working roll and the backup roll, the roll changing equipment used to replace the backup roll is used less frequently, which makes the roll changing equipment idle for a long time, wasting a lot of equipment investment. In addition, the installation of two sets of roll changing equipment also increases the subsequent maintenance workload and maintenance costs. Summary of the invention

[0041] The technical solution of the present invention has the following significant beneficial effects:

[0042] When the track-type roll-changing system of the present invention is used, the transverse roller device can drive the roll body to move along the transverse track mechanism, which is used to transport or temporarily store the new and old roll bodies. The roller feeding drive device can drive the rolling mill roller feeding device to move along the roll-changing track mechanism, wherein the roll-changing track mechanism can extend to the rolling mill, so that the roller feeding 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; or, the roll body can be placed on the rolling mill roller feeding device, and the rolling mill roller feeding device is pushed by the roller feeding drive device to send 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 shifting track mechanism, interaction can be generated between the transverse shifting 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 shifting roller device and the rolling mill roll feeding device and the roll feeding drive device, thereby conveniently realizing the pushing in of new rolls and the pulling out of old rolls to complete the roll changing operation.

[0044] The track-type roll changing system of the present invention cooperates with the track roll changing device through the transverse shift roll changing device, and the support rolls and working rolls on the rolling mill can be replaced respectively through the same roll feeding drive device, which significantly improves the utilization rate of the roll feeding drive device. When performing the roll changing operation, the roll feeding drive device transports the new roll body to the transverse shift roller device, and the transverse shift roller device can temporarily store and transport the new and old roll bodies, and cooperates with the roll feeding drive device to perform reciprocating motion along the roll changing track mechanism to complete the roll changing operation of pushing in the new roll and pulling out the old roll, which greatly improves 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, thereby reducing the deflection deformation of the rotating transverse track, 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 described embodiments 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 creative work are within the scope of protection of the present invention.

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

[0076] On the whole, when the track-type roll-changing system is in use, the transverse roller device 2 can drive the roll body to move along the transverse track mechanism 1, which is used to transport or temporarily store the new and old roll bodies. The roller feeding drive device 5 can drive the rolling mill roller feeding device 4 to move along the roll-changing track mechanism 3. Among them, the roll-changing track mechanism 3 can extend to the rolling mill 500, so that the roller feeding drive device 5 can push the roll body into the rolling mill 500 or pull it out of the rolling mill 500, thereby completing the roll-changing operation. Alternatively, the roll body can be placed on the rolling mill roller feeding device 4, and the rolling mill roller feeding device 4 is pushed by the roller feeding drive device 5 to send the roll body into the rolling mill 500 or pull it out of the rolling mill 500, thereby completing the roll-changing operation. By connecting the roll changing track mechanism 3 and the transverse moving track mechanism 1, interaction can be generated between the transverse moving roller device 2 and the rolling mill roll feeding device 4 and the roll feeding drive device 5, so that the roll body can be temporarily stored and transported between the transverse moving roller device 2 and the rolling mill roll feeding device 4 and the roll feeding drive device 5, so as to conveniently realize the pushing in of the new roll and the pulling out of the old roll to complete the roll changing operation.

[0077] In the embodiments of the present invention, 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 working roll changing track 31 can be used to transport the working roll 91, and the backing roll changing track 32 can be used to transport the backing roll 92. By arranging the working roll changing track 31 and the backing roll changing track 32 at intervals in the height direction, it is possible to avoid interference between the working roll changing track 31 and the backing roll changing track 32 during use, so that the working roll 91 and the backing roll 92 in the rolling mill 500 can be changed by the roll changing track mechanism 3.

[0079] Specifically, the working roll changing track 31 can be arranged along the center line direction of the mill 500 entrance and exit, so as to facilitate the transportation of the working rolls 91 in and out of the mill 500. The backup roll changing track 32 can be arranged parallel to the lower side of the working roll changing track 31 for transporting 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 part arranged on the working roll body, and the supporting roll 92 may include a supporting roll body and an assembly part arranged 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 arranged in sequence, 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] By setting the turning track section 33, a space can be formed for the support roller 92 to enter and exit the support roller changing track 32. By turning the track section 33, the working roll changing track 31 and the support roller changing track 32 will not interfere with each other during use, and the track-type roll changing system can be used to realize the roll changing operation of the working roll 91 and the roll changing operation of the support roll 92 respectively.

[0084] When replacing the working roll 91, the turning 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 turning track section 33 is turned 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 hoisted into or out of the support roll changing track 32 by the hoisting equipment.

[0085] In the embodiments of the present invention, Figure 4 and Figure 5The fixed track segment 34 includes two fixed guide rails 37 arranged side by side, and the flipping track segment 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 segment 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 turning guide rail 35 around the extension direction of the turning track section 33, a space for the support roller 92 to enter and exit the support roller changing track 32 can be quickly and conveniently formed. When the support roller 92 is replaced, the two turning guide rails 35 are moved away from each other by controlling the swing angle of the turning guide rail 35, 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 by a lifting device.

[0087] In the embodiments of the present invention, 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 flip driving device 362 can be a telescopic device, such as a hydraulic cylinder or a gas cylinder, which is not limited here. The telescopic rod of the telescopic device is connected to one end of the crank structure 361, and the crank structure 361 is pushed by the telescopic rod to drive the flip guide rail 35 to flip. The telescopic device can quickly and efficiently drive the flip guide rail 35 to achieve flipping or falling operations.

[0089] Of course, the designer can also use a crane to drive the flip guide 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 35, and a motor or a hydraulic motor is used to drive the flip guide 35 to rotate, thereby realizing the flip or fall operation.

[0090] In the embodiments of the present invention, Figure 5 and Figure 6 The roller feeding driving 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 at both sides of the rolling mill 500. The roll changing vehicle 51 can push the roll body into or out of the rolling mill 500 along the support roll changing rails 32, thereby completing the roll changing operation.

[0092] The roll-changing vehicle 51 can be driven by a motor and a reducer driving gear. The roll-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 roll-changing vehicle 51 is running.

[0093] In order to enable the roll changing vehicle 51 to better pull the support roll 92 or the working roll 91, a hook structure may be provided on the roll changing vehicle 51, and no limitation is made here. For example, two hooks of different heights may be provided at the front end of the roll changing vehicle 51, the upper hook being used to replace the working roll 91, and the lower hook being used to replace the support roll 92.

[0094] Furthermore, a guide structure 8 may be provided between the roll-changing vehicle 51 and the supporting roll-changing track 32 to ensure the smooth operation of the roll-changing vehicle 51, and an anti-rollover structure may be provided between the roll-changing vehicle 51 and the supporting roll-changing track 32, which are not limited here. Among them, an audible and visual alarm may be provided on the roll-changing vehicle 51 to issue an operation warning when the roll-changing vehicle 51 moves to ensure safe operation.

[0095] In the embodiments of the present invention, 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, and 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 car. A hook can be provided at one end of the roll-changing transition car 41 close to the rolling mill 500 and at one end away from the rolling mill 500. The hook at the side of the roll-changing transition car 41 away from the rolling mill 500 can be combined with the upper hook of the roll-changing car 51 to transmit power and realize the roll-changing action.

[0097] When replacing the working roll 91 , the end of the roll-changing transition car 41 close to the rolling mill 500 is connected to the hook on the operating side bearing seat of the new and old working rolls 91 through the hook 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 vehicle 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 end of the roll-changing transition car 41 close to the rolling mill 500 can also be combined with the hook on the maintenance platform through a hook, which is not limited here.

[0100] Of course, as another alternative embodiment of the hook, an independent support roller trailer 95 can be provided in the rolling mill 500 for transporting the support roller 92. A hook can be provided on the support roller trailer 95, while no hook is provided on the bearing seat of the support roller 92. This is not limited here. When the roll changing operation is performed, the bearing seat of the support roller 92 is seated on the support roller trailer 95, and the support roller 92 is transported by the support roller trailer 95. Among them, rollers or slides can be provided under the support roller trailer 95, so that the support roller trailer 95 can move on the support roller change track 32, and is used to transport the support roller 92 in and out of the rolling mill 500.

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

[0102] The roller changing bracket 300 can be used to replace or overhaul and maintain the support roller 92. Specifically, the roller changing bracket 300 may have an operating side and a transmission side, and the lower parts of the operating side and the transmission side are provided with a lower plane structure, which can be placed on the plane of the bearing seat of the lower support roller 92, and has better working stability. Among them, stoppers can be provided on both sides of the lower plane structure to match with the bearing seat of the lower support roller 92, which has the advantages of accurate positioning and reliable matching. Furthermore, a V-shaped keyway can be provided in the middle of the lower plane structure to match with the V-shaped key on the bearing seat of the lower support roller 92, which has the advantages of accurate positioning and reliable matching.

[0103] An upper plane structure is provided on the upper part of the operation side and the transmission side of the roller changing bracket 300, and the bearing seat of the upper supporting roller 92 is provided on the upper plane structure, which has better working stability. A positioning pin is provided in the middle of the upper plane structure, which is used to cooperate with the pin hole provided on the bearing seat of the upper supporting roller 92, and has the advantages of accurate positioning and reliable cooperation.

[0104] In the embodiments of the present invention, 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, the platform telescopic cover plate 7 can be arranged above the roll-changing vehicle 51. The platform telescopic cover plate 7 can cover the closed operation passage plane of the roll-changing track mechanism 3. Further, a step ladder can be arranged on the roll-changing vehicle 51 to facilitate the operator to enter the roll-changing vehicle 51.

[0106] In the embodiments of the present invention, 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 can controllably connect 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 transverse track 11 and the second transverse track 12 are arranged at intervals in the same direction, and the rotating transverse track 13 controllably connects 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 transverse roller device 2 can move along the transverse track mechanism 1 for roller replacement. When the rotating transverse track 13 disconnects the first transverse track 11 and the second transverse track 12, the rotating transverse track 13 can make way for the support roller 92 to pass through, thereby avoiding interference between the support roller 92 and the transverse track 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, Fig.13 and Fig.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, and 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 moving between the first transverse rail 11, the rotating transverse rail 13 and the second transverse rail 12.

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

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

[0113] In the embodiments of the present invention, Fig.15 The track support structure 14 also includes at least one third support portion 143 arranged between the first support portion 141 and the second support portion 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 portion 143.

[0114] By setting 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 moving track 13 can be supported by the third support portion 143, thereby reducing the track span of the rotating and transverse moving track 13, and further reducing the deflection deformation of the rotating and transverse moving track 13.

[0115] Specifically, a support that matches the third support portion 143 may be provided on the rotation and transverse movement track 13, and the support may be detachably mounted on the rotation and transverse movement track 13. When the support is worn, the support may be disassembled and replaced. Of course, the support may also be fixedly mounted on the rotation and transverse movement device, which is not limited here.

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

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

[0118] Specifically, the support roll changing track 32 can be arranged along the arrangement direction of the roll bodies in the rolling mill 500. And by vertically connecting the rotating and traversing track 13 with the support roll changing track 32, it is convenient to control the movement direction of the roll bodies, so that the roll bodies transported on the support roll changing track 32 can be arranged in the same direction as the roll bodies in the rolling mill 500, which is convenient for the subsequent installation of the roll bodies on the rolling mill 500.

[0119] Furthermore, when the roller changing vehicle 51 transports the support roller 92, the rotation and transverse track 13 can be controlled to avoid interference with the support roller 92, thereby improving the convenience of transporting the support roller 92. Furthermore, when the support roller 92 is transported to the rotation and transverse track 13, the support roller 92 can also be transferred to the transverse roller device 2 in a translational manner.

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

[0121] In an embodiment of the present invention, the rotating and transverse moving track 13 includes two rotating and transverse moving guide rails 131 , wherein one of the rotating and transverse moving guide rails 131 is hinged to the first transverse moving track 11 , and the other rotating and transverse moving guide rail 131 is hinged to the second transverse moving 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, the designer may 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, Fig.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 driving device 132 may include a telescopic device, such as a hydraulic cylinder or a pneumatic cylinder, which drives the rotational transverse guide rail 131 to rotate around the hinge point through a telescopic rod. The rotational transverse guide rail 131 is driven to rotate around the hinge point by starting the telescopic device, thereby making the rotational transverse guide rail 131 form a connected state or a disconnected state.

[0126] In an embodiment of the present invention, 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 are movable on the transverse track mechanism 1 .

[0127] Specifically, a roller table can be provided on the first transverse roller vehicle 21 and the second transverse roller vehicle 22, and the roller body can be placed on the roller table for transportation. Of course, the designer can also provide a roller changing bracket 300 on the roller table according to the use requirements, and the roller body can be placed or replaced by the roller changing bracket 300.

[0128] Further, the first transverse roller trolley 21 is movably arranged on the first transverse track 11, and the second transverse roller trolley 22 is movably arranged on the second transverse track 12. When the rotating transverse track 13 connects the first transverse track 11 and the second transverse track 12, the first transverse roller trolley 21 can move along the first transverse track 11 and the rotating transverse track 13 to the second transverse track 12, and the second transverse roller trolley 22 can move along the second transverse track 12 and the rotating transverse track 13 to the first transverse track 11. Designers can control the movement modes of the first transverse roller trolley 21 and the second transverse roller trolley 22 according to the needs of use, and no specific restrictions are made here.

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

[0130] Specifically, the first guide slide 81 may be disposed at the lower portion of the first transverse roller trolley 21, and the first transverse roller trolley 21 slidably cooperates with the transverse guide slide 83 disposed on the transverse track mechanism 1 through 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 disposed at the lower portion of the second transverse roller trolley 22, and the second transverse roller trolley 22 slidably cooperates with the transverse guide slide 83 disposed on the transverse track mechanism 1 through 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 may be arranged between the rolling mill 500 and the transverse track mechanism 1, and a platform track may be arranged 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 may be detachably arranged to prevent the roller body from being affected when 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 a 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, Fig.10 The transverse shift roller changing device 100 also includes a first transverse shift driving device 23 and a second transverse shift driving device 24 . The first transverse shift driving device 23 is connected to the first transverse shift roller vehicle 21 , and the second transverse shift driving device 24 is connected to the second transverse shift 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 second transverse roller trolley 22 to move along the transverse track mechanism 1.

[0137] In the embodiments of the present invention, Fig. 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, and the first connecting portion 25 and the second connecting portion 26 are detachably connected.

[0138] Specifically, the first connection portion 25 and the second connection portion 26 can be detachably connected by bolts. Of course, the first connection portion 25 and the second connection portion 26 can also be detachably connected by buckles, 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, 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, and 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, and 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 one end of the first transverse track 11 away from the second transverse track 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 track mechanism 1, the first transverse roller trolley 21 can drive the first telescopic cover plate 61 to cover the first transverse track 11. One end of the second telescopic cover plate 62 is fixedly arranged at one end of the second transverse track 12 away from the first transverse track 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 track mechanism 1, the second transverse roller trolley 22 can drive the second telescopic cover plate 62 to cover the second transverse track 12.

[0142] The first telescopic cover plate 61 and the second telescopic cover plate 62 can protect the first transverse track 11 and the second transverse track 12, and can prevent foreign matter from entering the transverse track mechanism 1 and affecting the operation stability of the first transverse roller vehicle 21 and the second transverse roller vehicle 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, which can be used in conjunction with Figure 1 and Figure 2 , comprising a rolling mill 500, the track-type roll changing system in the above-mentioned embodiment and a transition track structure, wherein the track-type roll changing system is connected to the rolling mill 500 via the transition track structure. The specific structure, working principle and beneficial effects of the track-type roll changing system are the same as those described in the above-mentioned embodiment, and are not described in detail here. The rolling mill system can improve the roll changing efficiency and the utilization rate of the roll changing equipment through the track-type roll changing system.

[0144] In an embodiment of the present invention, the rolling mill 500 includes a frame 9, and working rolls and supporting rolls arranged on the frame 9, the transition track structure includes an in-machine working roll track 93 arranged below the working roll and an in-machine supporting roll track 94 arranged below the supporting roll, the track-type roll changing system is connected to the in-machine working roll track 93 through the working roll changing track 31, and the track-type roll changing system is connected to the in-machine supporting roll track 94 through the supporting roll changing track 32.

[0145] The working roll track 93 in the machine facilitates the working roll 91 to enter and exit the rolling mill 500, which is beneficial to improving the roll changing efficiency of the working roll 91. The supporting roll track 94 in the machine facilitates the supporting roll 92 to enter and exit the rolling mill 500, which is beneficial to improving the roll changing efficiency of the supporting roll 92.

[0146] Furthermore, the frame 9 can be raised and lowered. The frame 9 can be driven to rise and fall by a hydraulic device, so that the support roller 92 or the working roller 91 can be easily removed from the frame 9. The designer can adjust the lifting height of the frame 9 according to the installation method of the support roller 92 and the working roller 91 to facilitate the removal of the roller body, and no specific restrictions are made here.

[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.
