Description

Technical Field

[0001] This invention relates to the field of cold rolling production technology, and in particular to a submerged roll replacement device for the cleaning section. Background Technology

[0002] Cold rolling uses hot-rolled steel coils as raw materials, and after pickling to remove oxide scale, it is continuously cold rolled. The finished product is hard-rolled coil. Due to the work hardening caused by continuous cold deformation, the strength and hardness of the hard-rolled coil increase and the toughness and plasticity decrease. Therefore, the stamping performance will deteriorate, and it can only be used for parts with simple deformation. At the entrance of the cold rolling cleaning and unloading line, the submerged roll can guide the cold-rolled raw materials passing through it.

[0003] In current technology, the outer wall of the submerged roll and the cold-rolled raw material are squeezed and rubbed against each other, which means that the submerged roll, as a consumable part, needs to be replaced regularly. The maintenance and replacement of the submerged roll requires disassembly and relocation, which requires structures such as overhead cranes and clamps. After the clamps are engaged with the shaft of the submerged roll, the overhead crane is connected to the clamps through hooks. The displacement of the submerged roll can be controlled by controlling the overhead crane, so as to realize the disassembly and relocation of the submerged roll.

[0004] However, in the existing technology, during the replacement of the submerged roller by the mobile trolley, the connection between the trolley and the hook is made by steel wire, which makes it difficult to transfer force. In addition, the process of clamping the clamp to the submerged roller shaft also takes a certain amount of time. As a result, the disassembly and relocation of the submerged roller takes a lot of time, resulting in low efficiency in the replacement of the submerged roller.

[0005] Therefore, a submerged roller replacement device for the washing section is proposed to address the above problems. Summary of the Invention

[0006] Therefore, the technical problem to be solved by the present invention is to overcome the problems existing in the prior art.

[0007] To solve the above-mentioned technical problems, the present invention provides a submerged roller replacement device for a washing section, including a base. A moving track is parallel to the top surface of the base. A U-shaped replacement seat is slidably connected above the base. A roller shaft bracket is fixedly connected to the center of the top surface of the U-shaped replacement seat. A clamping seat is provided inside the roller shaft bracket. Clamping fixing plates are fixedly connected to the inner walls of both sides of the clamping seat near the center by bolts. A first through hole is opened on one side of the upper part of the two clamping fixing plates. A second through hole is opened on the other side of the upper part of the two clamping fixing plates. A first inclined wall pressure block is installed inside one side of the two clamping fixing plates. A first pressure block shaft is fixedly connected to the inside of the first inclined wall pressure block near the center. The first inclined wall pressure block is hinged to the first through hole via the first pressure block shaft. A second inclined wall pressure block is installed inside the other side of the clamping fixing plate. A second pressure block shaft is fixedly connected to the inside of the second inclined wall pressure block near the center. The second inclined wall pressure block is hinged to the second through hole via the second pressure block shaft.

[0008] In one embodiment of the present invention, a roller mounting lug is fixedly connected to the upper part of one end of the roller bracket, and a straight groove opening is provided on the adjacent side wall of the two roller mounting lugs. Clamping seat shafts are fixedly connected to both sides of the clamping seat corresponding to the roller mounting lugs, and the outer walls of the two clamping seat shafts are respectively engaged with the two straight groove openings.

[0009] In one embodiment of the present invention, the inner wall of the clamping seat is provided with retaining ring tracks on both sides, and retaining ring sliders are slidably connected to the inner walls of the two retaining ring tracks. A semi-circular retaining ring is fixed between the two retaining ring sliders, and a guide bevel is provided on one side of the inner ring of the semi-circular retaining ring.

[0010] In one embodiment of the present invention, a retaining plate is fixedly connected to the center of the other side of the inner ring of the semicircular retaining ring, and a contact seat is fixedly connected to the lower side of one side of the retaining plate, and one side of the contact seat is in contact with the side wall of the first inclined wall pressure block.

[0011] In one embodiment of the present invention, a clearance slot is provided on one side of the first inclined wall pressure block, and a semi-circular retaining ring is fixedly connected to the top surface of the semi-circular retaining ring, wherein the outer wall of the semi-circular retaining ring engages with the inner wall of the clearance slot.

[0012] In one embodiment of the present invention, connecting brackets are fixedly connected to the outer wall of the clamping seat near both ends. A hydraulic jack is mounted on one end of each of the two connecting brackets via a shaft. A fixing cross plate is fixedly connected to the bottom of each of the two hydraulic jacks. The two fixing cross plates are respectively fixed to the inner sides of the roller support.

[0013] In one embodiment of the present invention, an oil pump bracket is fixedly connected to one side of the outer wall of the roller bracket, and a manual hydraulic pump is fixedly connected above the oil pump bracket. One end of the manual hydraulic pump is connected to a control valve through a pipeline.

[0014] In one embodiment of the present invention, control handles are fixedly connected to the inside of the control valve near both ends, and oil pipe interfaces are provided on one side of each of the two control handles.

[0015] In one embodiment of the present invention, roller sliders are fixedly connected to the bottom of the U-shaped replacement seat near the corner, and the four roller sliders are respectively located inside the two moving tracks.

[0016] In one embodiment of the present invention, a track scraper is fixedly connected to one side of the roller slider, and the outer wall of the track scraper engages with the inner wall of the moving track.

[0017] The technical solution of the present invention has the following advantages compared with the prior art:

[0018] 1. In this invention, as the clamping seat gradually moves towards the submerged roller, one end of the submerged roller's shaft first contacts one side of the first inclined wall pressure block. As it gradually approaches, it continuously drives the first inclined wall pressure block to flip upwards. During this process, the second inclined wall pressure block also gradually flips upwards under the transmission of the first inclined wall pressure block. When the submerged roller's shaft moves to a state where the first inclined wall pressure block is flush with the clamping seat, it stops moving. At this time, the first inclined wall pressure block fixes the submerged roller by contacting the outer wall of the shaft. The method of the first and second inclined wall pressure blocks cooperating with each other to squeeze and limit the submerged roller eliminates the process of installing clamps. Moreover, the method of removing the submerged roller as a whole by the U-shaped replacement seat is less difficult to operate than the connection method of the overhead crane wire, thereby increasing the work efficiency during the removal and relocation of the submerged roller.

[0019] 2. In order to prevent the semi-circular locking block from interfering with the first inclined wall pressing block during the flipping process, the present invention uses a semi-circular retaining ring to engage with the clearance slot through the semi-circular locking block. This ensures that the semi-circular locking block does not interfere with the first inclined wall pressing block during the flipping process without affecting the flipping of the first inclined wall pressing block.

[0030] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand and implement the present invention. However, the embodiments described are not intended to limit the present invention.

[0031] Please see Figures 1-8As shown, a submerged roller replacement device for a washing section includes a base 1. A moving track 11 is parallel to the top surface of the base 1. A U-shaped replacement seat 2 is slidably connected above the base 1. A roller shaft support 21 is fixedly connected to the center of the top surface of the U-shaped replacement seat 2. A clamping seat 3 is provided inside the roller shaft support 21. Clamping fixing plates 31 are fixedly connected to the inner walls of both sides of the clamping seat 3 near the center by bolts. A first through hole 312 is opened on one side of the upper part of each of the two clamping fixing plates 31, and a second through hole 312 is opened on the other side of the upper part of each of the two clamping fixing plates 31. Two through holes 312, a first inclined wall pressure block 33 is installed inside one side of the two clamping and fixing plates 31, a first pressure block shaft 331 is fixedly connected to the inside of the first inclined wall pressure block 33 near the center, the first inclined wall pressure block 33 is hinged to the first through hole 312 via the first pressure block shaft 331, a second inclined wall pressure block 34 is installed inside the other side of the clamping and fixing plates 31, a second pressure block shaft 341 is fixedly connected to the inside of the second inclined wall pressure block 34 near the center, the second inclined wall pressure block 34 is hinged to the second through hole 312 via the second pressure block shaft 341;

[0032] To increase efficiency during the removal of the submerged roll, when removal is required, the submerged roll is first disconnected from all connections to the cold rolling equipment, exposing one end of the roll's shaft. At this point, the movable U-shaped replacement seat 2 moves closer to the submerged roll, allowing the clamping seat 3 to gradually approach the roll's shaft, thus fitting the roll's shaft into the clamping seat 3. Due to the structural features of the inclined walls of the first inclined wall pressure block 33 and the second inclined wall pressure block 34, the first and second inclined wall pressure blocks 33 and 34 can withstand external forces. In a vertical position with the heavier end at the bottom, as the clamping seat 3 gradually moves towards the submerged roller, one end of the submerged roller's shaft first contacts one side of the first inclined wall pressure block 33. As it approaches, it causes the bottom of the first inclined wall pressure block 33 to flip upwards. During this process, the bottom of the second inclined wall pressure block 34 also gradually flips upwards under the transmission of the first inclined wall pressure block 33. The movement stops when the shaft of the submerged roller reaches a state where the first inclined wall pressure block 33 is flush with the clamping seat 3. At this point, the first inclined wall pressure block 33, through its contact with the submerged roller... The contact between the outer wall of the shaft provides support. When the bottom surface of the first inclined wall pressure block 33 is parallel to the submerged roller, the inclined wall of the second inclined wall pressure block 34 can press against it, so that the first inclined wall pressure block 33 has a certain inclination angle to press against the outer wall of the shaft of the submerged roller, thus achieving relative fixation between the clamping seat 3 and the submerged roller. When it is necessary to separate the clamping seat 3 and the submerged roller, the lighter end of the first inclined wall pressure block 33 and the second inclined wall pressure block 34 is pressed down to remove the pressure from the heavier end of the first inclined wall pressure block 33 and the second inclined wall pressure block 34 on the output shaft of the submerged roller. Pressure is applied, and the U-shaped replacement seat 2 moves in the opposite direction, causing the clamping seat 3 to detach from the shaft casting of the submerged roller. At this time, under the action of gravity, the first inclined wall pressure block 33 and the second inclined wall pressure block 34 are reset, and the submerged roller can also detach from the device. The method of squeezing and limiting the submerged roller by the cooperation between the first inclined wall pressure block 33 and the second inclined wall pressure block 34 omits the process of installing the clamp. Moreover, the method of removing the submerged roller as a whole by the U-shaped replacement seat 2 is less difficult to operate than the connection method of the overhead crane steel wire, thereby increasing the work efficiency in the process of removing and moving the submerged roller.

[0033] Furthermore, such as Figure 2 and Figure 6 As shown, roller mounting ears 22 are fixedly connected to the top of one end of the roller bracket 21. Straight groove openings 221 are opened on the adjacent side walls of the two roller mounting ears 22. Clamping seat shafts 35 are fixedly connected to the two sides of the clamping seat 3 corresponding to the roller mounting ears 22. The outer walls of the two clamping seat shafts 35 are respectively engaged with the two straight groove openings 221.

[0034] In order to adjust the relative angle and relative height of the clamping seat 3, the roller support 21 cooperates with the clamping seat shaft 35 on the clamping seat 3 through the straight groove opening 221. This allows the clamping seat 3 and the roller support 21 to be fixed to each other, while also enabling the clamping seat 3 to be moved up and down and the relative angle between it and the base 1 to be adjusted within a certain range after the clamping seat 3 and the submerged roller are fixed to each other.

[0035] Furthermore, such as Figure 2 and Figure 5 As shown, the inner wall of the clamping seat 3 is provided with retaining ring tracks 36 on both sides, and retaining ring sliders 37 are slidably connected to the inner walls of the two retaining ring tracks 36. A semi-circular retaining ring 371 is fixed between the two retaining ring sliders 37, and a guide angle 372 is provided on one side of the inner ring of the semi-circular retaining ring 371.

[0036] When the casting of the submerged roller shaft is inserted into the clamping seat 3, it can first contact the semi-circular retaining ring 371, thereby increasing the relative contact area between the outer wall of the submerged roller shaft and the first inclined wall pressure block 33. This increases the pressing stability of the first inclined wall pressure block 33 on the outer wall of the submerged roller shaft. When there is a certain deviation between the submerged roller shaft and the semi-circular retaining ring 371, the guide angle 372 can also guide the submerged roller shaft to prevent the semi-circular retaining ring 371 and the submerged roller shaft from having a hard collision and causing damage.

[0037] Furthermore, such as Figure 2 and Figure 5 As shown, a baffle plate 373 is fixedly connected to the center of the other side of the inner ring of the semicircular retaining ring 371. A contact seat 374 is fixedly connected to the lower side of one side of the baffle plate 373. One side of the contact seat 374 is in contact with the side wall of the first inclined wall pressure block 33.

[0038] In order to reduce the compression of the first through hole 311 during the flipping process of the first inclined wall pressure block 33, which would cause the first through hole 311 to become entangled and deformed, the shaft of the submerged roller is engaged and positioned with the inner wall of the semi-circular retaining ring 371 and then abuts against the baffle plate 373. This allows the semi-circular retaining ring 371 to follow the submerged roller in applying an upward flipping force to the first inclined wall pressure block 33. During this process, the contact seat 374, which protrudes slightly from the baffle plate 373, first contacts the side wall of the first inclined wall pressure block 33. This reduces the upward compression of the contact surface of the first inclined wall pressure block 33 by the submerged roller and prevents the first through hole 311 from being squeezed and deformed.

[0039] Furthermore, such as Figure 2 and Figure 6 As shown, a clearance slot 332 is provided on one side of the first inclined wall pressure block 33, and a semi-circular retaining ring 371 is fixedly connected to the top surface of the semi-circular retaining ring 371. The outer wall of the semi-circular retaining ring 375 and the inner wall of the clearance slot 332 are engaged with each other.

[0040] To prevent motion interference between the first inclined wall pressing block 33 and the semi-circular engaging block 375 during the flipping process, the semi-circular retaining ring 371 engages with the clearance slot 332 through the semi-circular engaging block 375. This ensures that the semi-circular engaging block 375 does not interfere with the first inclined wall pressing block 33 during the flipping process without affecting the flipping of the first inclined wall pressing block 33.

[0041] Furthermore, such as Figure 3 and Figure 6 As shown, the outer wall of the clamping seat 3 is fixedly connected to the connecting brackets 38 near the two ends. One end of the two connecting brackets 38 is equipped with a hydraulic jack 4 through a shaft. The bottom of the two hydraulic jacks 4 is fixedly connected to a fixing plate 23. The two fixing plates 23 are respectively fixed to the inner sides of the roller bracket 21.

[0042] To facilitate the lifting or angle adjustment of the submerged roller, a hydraulic jack 4 is used to connect and fix the horizontal plate 23 and the clamping seat 3. This allows the horizontal height of the clamping seat 3 and its angle with the horizontal direction to be controlled within a certain range under the synchronous or asynchronous extension and retraction of the hydraulic jacks 4 on both sides, thus facilitating the lifting or angle adjustment of the submerged roller. The connecting bracket 38 serves as the intermediate connecting structure, ensuring that the connection between the hydraulic jack 4 and the clamping seat 3 is not adversely affected during the angular deflection of the clamping seat 3.

[0043] Furthermore, such as Figure 6 As shown, an oil pump bracket 24 is fixedly connected to one side of the outer wall of the roller bracket 21, and a manual hydraulic pump 5 is fixedly connected above the oil pump bracket 24. One end of the manual hydraulic pump 5 is connected to a control valve 51 through a pipe.

[0044] In order to provide hydraulic lifting force to the hydraulic jack 4, the manual hydraulic pump 5 is installed through the oil pump bracket 24. The control valve 51 is a connection structure set at the output end of the manual hydraulic pump 5 to connect with the hydraulic jack 4. After the manual hydraulic pump 5 is connected to the hydraulic jack 4, it provides hydraulic lifting force to the hydraulic jack 4.

[0045] Furthermore, such as Figure 6 As shown, control handles 52 are fixedly connected to the inside of the control valve 51 near both ends. Each of the two control handles 52 has an oil pipe interface 53 on one side. The two oil pipe interfaces 53 are respectively connected to two hydraulic jacks 4 through oil pipes.

[0046] To control the lifting and deflection angle of the clamping seat 3, oil pipe interfaces 53 and hydraulic jacks 4 are connected by oil pipes to achieve oil circuit linkage between manual hydraulic pump 5 and hydraulic jacks 4. This allows manual hydraulic pump 5 to provide hydraulic lifting force to hydraulic jacks 4, while two control handles 52 can control the oil circuits of the two oil pipe interfaces 53 respectively. Thus, the device can control the lifting and deflection angle of the clamping seat 3 by rotating the two control handles 52.

[0047] Furthermore, such as Figure 1 and Figure 7 As shown, roller sliders 25 are fixedly connected to the bottom of the U-shaped replacement seat 2 near the corner, and the four roller sliders 25 are respectively located inside the two moving tracks 11;

[0048] In order to reduce the resistance at one end of the U-shaped replacement seat 2, the U-shaped replacement seat 2 slides with the moving track 11 through the roller slider 25, so that the U-shaped replacement seat 2 as a whole can be displaced under the restriction of the moving track 11, so as to realize the disassembly and relocation of the submerged roller. The roller slider 25 can reduce the resistance at one end of the U-shaped replacement seat 2 by reducing the contact area through the interaction between the roller and the moving track 11.

[0049] Furthermore, such as Figure 1 and Figure 7 As shown, a track scraper 26 is fixedly connected to one side of the roller slider 25, and the outer wall of the track scraper 26 is engaged with the inner wall of the moving track 11.

[0050] To prevent foreign objects from entering the moving track 11 and affecting the rotation of the roller slider 25, the scrapers 26 on both sides of the track are in contact with the inner wall of the moving track 11. This prevents foreign objects from entering the moving track 11 and affecting the rotation of the roller slider 25 when the U-shaped changing seat 2 moves, without affecting the rolling of the roller slider 25.

[0051] Working Principle: To increase the efficiency of dismantling and moving the submerged roll, when it is necessary to dismantle and move the submerged roll, first disconnect all connections between the submerged roll and the cold rolling equipment, exposing one end of the submerged roll's shaft. At this time, the movable U-shaped replacement seat 2 moves towards the submerged roll, allowing the clamping seat 3 to gradually approach the shaft of the submerged roll, so that the shaft of the submerged roll is sleeved in the clamping seat 3. Due to the structural characteristics of the inclined walls of the first inclined wall pressure block 33 and the second inclined wall pressure block 34, the first inclined wall pressure block 33 and the second inclined wall pressure block 34 are in a vertical state without external force, with the heavier end at the bottom. As the clamping seat 3 gradually moves towards the submerged roll, one end of the submerged roll's shaft can first engage with one side of the first inclined wall pressure block 33. The two sides come into contact and gradually approach each other, causing the bottom of the first inclined wall pressure block 33 to flip upwards. During this process, the bottom of the second inclined wall pressure block 34 can also gradually flip upwards under the drive of the first inclined wall pressure block 33. When the shaft of the submerged roller moves to a state where the first inclined wall pressure block 33 is flush with the clamping seat 3, it stops moving. At this time, the first inclined wall pressure block 33 supports the submerged roller shaft by contacting the outer wall of the submerged roller shaft. When the bottom surface of the first inclined wall pressure block 33 is parallel to the submerged roller, the inclined wall of the second inclined wall pressure block 34 can press against it, so that the first inclined wall pressure block 33 has a certain inclination angle to press against the outer wall of the submerged roller shaft, thus achieving relative fixation between the clamping seat 3 and the submerged roller. When it is necessary to separate the clamping seat 3 and the submerged roller, The lighter ends of the first inclined wall pressure block 33 and the second inclined wall pressure block 34 are pressed down, removing the squeezing force on the output shaft of the submerged roller from the heavier ends of the first inclined wall pressure block 33 and the second inclined wall pressure block 34. At this time, the U-shaped replacement seat 2 moves in the reverse direction, causing the clamping seat 3 to disengage from the shaft casting of the submerged roller. Under the action of gravity, the first inclined wall pressure block 33 and the second inclined wall pressure block 34 return to their original positions, and the submerged roller can also disengage from the device. The method of squeezing and limiting the submerged roller by the cooperation between the first inclined wall pressure block 33 and the second inclined wall pressure block 34 omits the process of installing the clamps. Moreover, the method of removing the submerged roller by the U-shaped replacement seat 2 as a whole is easier to operate than the connection method of the overhead crane wire, thereby increasing the work efficiency during the dismantling and relocation of the submerged roller. In order to make the clamping seat 3 relatively The angle and relative height can be adjusted by the roller support 21 cooperating with the clamping seat shaft 35 on the clamping seat 3 through the straight groove opening 221. This allows the clamping seat 3 and the roller support 21 to be fixed together, while also enabling the clamping seat 3 to move up and down within a certain range and adjust its relative angle with the base 1 after the clamping seat 3 and the submerged roller are fixed together. When the submerged roller shaft casting is inserted into the clamping seat 3, it can first contact the semi-circular retaining ring 371, thereby increasing the relative contact area between the outer wall of the submerged roller shaft and the first inclined wall pressure block 33, thus increasing the pressing stability of the first inclined wall pressure block 33 on the outer wall of the submerged roller shaft. When there is a certain deviation between the submerged roller shaft and the semi-circular retaining ring 371, the shaft of the submerged roller can also be guided by the guide angle 372.To prevent hard collisions and damage between the semicircular retaining ring 371 and the shaft of the submerged roller, and to reduce the deformation of the first through hole 311 caused by the compression of the first inclined wall pressure block 33 during its flipping process, the shaft of the submerged roller is positioned to fit against the inner wall of the semicircular retaining ring 371 and then abut against the baffle plate 373. This allows the semicircular retaining ring 371 to follow the submerged roller in applying an upward flipping force to the first inclined wall pressure block 33. During this process, the contact seat 374, which slightly protrudes from the baffle plate 373, first contacts the side wall of the first inclined wall pressure block 33, thereby reducing the upward compression of the contact surface of the first inclined wall pressure block 33 by the submerged roller and preventing deformation of the first through hole 311 due to compression. The semi-circular retaining ring 371 engages with the semi-circular retaining block 375 and the clearance slot 332 through the semi-circular retaining block 375. This ensures that the semi-circular retaining block 375 does not interfere with the first inclined wall pressure block 33 during its rotation, without affecting the rotation of the first inclined wall pressure block 33. To facilitate the lifting or angle adjustment of the submerged roller, the horizontal plate 23 and the clamping seat 3 are connected and fixed by the hydraulic jack 4. This allows the horizontal height of the clamping seat 3 and its angle with the horizontal direction to be controlled within a certain range under the synchronous or asynchronous extension and retraction of the hydraulic jacks 4 on both sides, thus facilitating the lifting or angle adjustment of the submerged roller. The connecting bracket 38 serves as the intermediate connecting structure, causing the clamping seat 3 to deflect at an angle. The process will not adversely affect the connection between the hydraulic jack 4 and the clamping seat 3. To provide hydraulic lifting force to the hydraulic jack 4, the manual hydraulic pump 5 is installed through the oil pump bracket 24. The control valve 51 is a connection structure set at the output end of the manual hydraulic pump 5 to connect with the hydraulic jack 4. After being connected to the hydraulic jack 4, the manual hydraulic pump 5 provides hydraulic lifting force to the hydraulic jack 4. To control the lifting and deflection angle of the clamping seat 3, oil pipes are connected to the oil pipe interface 53 and the hydraulic jack 4 respectively, realizing the oil circuit linkage between the manual hydraulic pump 5 and the hydraulic jack 4. This allows the manual hydraulic pump 5 to provide hydraulic lifting force to the hydraulic jack 4, and the two control handles 52 can respectively control the two oil pipe interfaces 53. The oil circuit is controlled, enabling the device to control the lifting and deflection angle of the clamping seat 3 through the rotation of two control handles 52. To reduce resistance at one end of the U-shaped changing seat 2, the U-shaped changing seat 2 slides against the moving track 11 via roller slider 25, allowing the U-shaped changing seat 2 to move under the constraint of the moving track 11, thus enabling the device to remove and move the submerged roller. The roller slider 25 reduces resistance at one end of the U-shaped changing seat 2 by reducing the contact area through the interaction between the roller and the moving track 11. To prevent foreign objects from entering the moving track 11 and affecting the rotation of the roller slider 25, the scrapers 26 on both sides of the track are in contact with the inner wall of the moving track 11.To prevent foreign objects from entering the moving track 11 and affecting the rotation of the rollers in the roller slider 25 during the movement of the U-shaped changing seat 2, without affecting the rolling of the roller slider 25.

Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.
