[0002] In modern rolling mill operations, the hot rolling work roll balance cylinder weighs up to 2.7 tons and is a key component to ensure stable operation during the rolling process.

The reinstallation process is equally difficult. Due to the large weight of the balance cylinder, replacing spare parts on either side requires a lot of manpower and resources, and the maintenance time is long.

The term "two or more" includes two or more cases.

[0018] In modern rolling mill maintenance and repair, it is necessary to disassemble and assemble the balance cylinder blocks. The balance cylinder blocks are very heavy, especially for large rolling mill balance cylinders. Therefore, most rolling mill balance cylinder blocks are fixed on the archway. At present, during the maintenance process, it is often necessary to manually enter the rolling mill space. The rolling mill space is not only small, but also requires the use of different tools, including hoisting equipment. Therefore, the operation is not only cumbersome and the disassembly and assembly work cycle is long, but it also requires the use of hoisting equipment. In addition, the movement of personnel in the confined space poses a significant safety hazard.

[0019] To address the aforementioned issues, this application discloses a balance cylinder block disassembly and assembly device for replacing balance cylinder blocks in rolling mills. The disassembly and assembly device includes a movable base 1, a first drive mechanism 2, a second drive mechanism 3, and a replacement mechanism 4.

[0020] Please refer to the instruction manual appendix. Figure 1-5 The first drive mechanism 2 is located on the movable base 1. The replacement mechanism 4 is connected to the first drive mechanism 2 and the second drive mechanism 3. The first drive mechanism 2 can drive the replacement mechanism 4 to move along the first direction so that the replacement mechanism 4 is aligned with the installation position. The second drive mechanism 3 can drive the replacement mechanism 4 to move along the second direction so that the replacement mechanism 4 enters or separates from the installation position. The replacement mechanism 4 can be connected to or separated from the balance cylinder block. The first direction is the height direction of the rolling mill stand, and the second direction is perpendicular to the first direction.

[0021] During implementation, the mobile base 1 serves as the supporting foundation for the equipment, enabling the entire equipment to move in and out of the mill's maintenance space, bringing the equipment close to the installation position of the balance cylinder block. The mobile base 1 also acts as a support for transporting the mill's balance cylinder block. The mobile base 1 serves as a support platform on which the first drive mechanism 2, the second drive mechanism 3, and the replacement mechanism 4 are mounted. The first drive mechanism 2, as a powered sliding device, can slide the replacement mechanism 4 along a first direction, allowing the replacement mechanism 4 to slide relative to the mobile base 1. The mobile base 1 can be adjusted in the horizontal direction, and the first drive mechanism 2 can be perpendicular to the direction of movement of the mobile base 1. The second drive mechanism 3 can drive the replacement mechanism 4 to slide along a second direction, ensuring that the position of the replacement mechanism 4 corresponds to the installation position of the balance cylinder block in the mill, facilitating adjustment and alignment.

[0022] Meanwhile, the second drive mechanism 3 allows the replacement mechanism 4 to be detachably connected to the balance cylinder block. By connecting the balance cylinder block to the replacement mechanism 4, the replacement mechanism 4 can drive the balance cylinder block to move, thereby disassembling the balance cylinder block. Then, the first drive mechanism 2 places the balance cylinder block onto the movable base 1, and the movable base 1 drives the balance cylinder block to slide into / out of the rolling mill. During the process, only the fixing rods of the balance cylinder block need to be disassembled and the replacement mechanism 4 needs to be aligned. No hoisting equipment is required, so the operation is convenient and relatively safe.

[0023] The mobile base 1 is moved to the installation position of the balance cylinder block inside the rolling mill. The first drive mechanism 2 and the second drive mechanism 3 mounted on the mobile base 1 can adjust the replacement mechanism 4 so that the replacement mechanism 4 corresponds to the installation position of the balance cylinder block. The replacement mechanism 4 can be detachably connected to the balance cylinder block. The balance cylinder block can be removed by connecting the replacement mechanism 4, or the balance cylinder block can be pushed onto the stand of the rolling mill to complete the installation. This greatly simplifies the disassembly and assembly process of the balance cylinder block, reduces the operating pressure of the staff, and makes the operation safer and more reliable without the need for hoisting ropes.

[0024] For some embodiments of this application, please refer to the appendix to the specification. Figure 1-3 It is known that the mobile base 1 includes a mobile chassis 1, multiple load-bearing wheels 11 mounted on the mobile chassis 1, and an adjustment handle 12 rotatably connected to the mobile chassis 1. The mobile chassis 1 can be a heavy-duty steel chassis. The multiple load-bearing wheels 11 distribute the overall weight, improve the load-bearing capacity, and provide a moving function. The adjustment handle 12 is used to pull and control the movement of the mobile chassis 1 and adjust its direction.

[0025] For some embodiments of this application, please refer to the appendix to the specification. Figure 1 , 4And 5, the replacement mechanism 4 includes a support member 41 and multiple connecting members 42, the multiple connecting members 42 are slidably disposed on the support member 41, and the connecting members 42 are connected to or separated from the balance cylinder block; the support member 41 is drivenly connected to the first drive mechanism 2, the second drive mechanism 3 is disposed on the support member 41, the second drive mechanism 3 is drivenly connected to the multiple connecting members 42 to drive the multiple connecting members 42 to move along the second direction; wherein, the balance cylinder block has multiple mounting holes, the multiple connecting members 42 are correspondingly disposed to the multiple mounting holes, and the second drive mechanism 3 can drive the connecting members 42 to connect to the corresponding mounting holes.

[0026] During implementation, the support member 41 is slidably connected to the first drive mechanism 2, and the sliding direction of the support member 41 is perpendicular to the moving surface of the moving base 1. As the main body for the installation of the replacement mechanism 4, the support member 41 can drive the second drive mechanism 3 and multiple connecting members 42 to slide synchronously. The second drive mechanism 3 can synchronously transmit the movement of multiple connecting members 42, so that the connecting members 42 slide relative to the support member 41, so that the multiple connecting members 42 are detachably connected to the balance cylinder block. Specifically, the multiple connecting members 42 correspond to the multiple mounting holes of the balance cylinder block. The second drive mechanism 3 is used to make the multiple connecting members 42 slide to connect the multiple mounting holes, so as to achieve the purpose of supporting and moving the balance cylinder block.

[0027] For some embodiments of this application, please refer to the appendix to the specification. Figure 2-5 The second drive mechanism 3 includes a mounting housing 31, a drive assembly 32, and multiple adjusting members 33. The mounting housing 31 is mounted on the support member 41, the drive assembly 32 is mounted on the mounting housing 31, the drive assembly 32 is connected to the multiple adjusting members 33, the multiple adjusting members 33 are rotatably mounted on the mounting housing 31, the multiple adjusting members 33 correspond one-to-one with the multiple connecting members 42, the adjusting members 33 are connected to the corresponding connecting members 42, and the drive assembly 32 can drive the multiple connecting members 42 to move along the second direction by driving the adjusting members 33 to rotate.

[0028] During implementation, the second drive mechanism 3 is integrated into the mounting housing 31. The mounting housing 31 is fixedly connected to the support member 41, enabling the first drive mechanism 2 to synchronously adjust the positions of the support member 41 and the mounting housing 31. The drive assembly 32 provides power for the transmission of the second drive mechanism 3. The drive assembly 32 drives multiple adjusting members 33 to rotate. The adjusting members 33 are tubular structures. The multiple adjusting members 33 and multiple connecting members 42 are connected by a sliding fit, so that the multiple connecting members 42 can slide relative to the support member 41. After the multiple connecting members 42 slide into the mounting holes of the counterweight cylinder, the mounting holes and the connecting members 42 are used to complete the disassembly and assembly of the counterweight cylinder.

[0029] Specifically, the mounting hole can be an internal threaded hole, and the connector 42 can be a screw. When the connector 42 engages with the mounting hole, the counterweight cylinder block can slide or the connector 42 can enter the configuration cylinder block.

[0030] In some embodiments of this application, the drive assembly 32 includes a power component 321 and a plurality of transmission components 322, with each of the plurality of transmission components 322 corresponding to a plurality of adjustment components 33. The power component 321 is disposed on the mounting housing 31 and is connected to the plurality of transmission components 322 in a transmission manner to synchronously drive the plurality of transmission components 322.

[0031] During implementation, the power component 321 serves as the core power source for disassembly and assembly operations. Through cooperation with multiple transmission components 322, it distributes power to multiple adjustment components 33. The multiple transmission components 322 are connected to the multiple adjustment components 33, enabling the multiple transmission components 322 to synchronously drive the multiple adjustment components 33 to rotate. A single power component 321 can simultaneously drive the movement of multiple transmission components 322, which facilitates control and saves space in the equipment.

[0032] In some embodiments of this application, the power component 321 includes a power unit 3211, a circulation unit 3212, and a transfer unit 3213. The power unit 3211 is connected to the circulation unit 3212, the transfer unit 3213 is connected to the circulation unit 3212, and the transfer unit 3213 is connected to a plurality of transmission components 322.

[0033] During implementation, the power unit 3211, in cooperation with the circulating unit 3212, as shown in the appendix to the instruction manual... Figure 4 As shown, the power unit 3211 is composed of a central gear and a planetary gear. The circumferential part 3212 has internal teeth that mesh with the planetary gears, causing the circumferential part 3212 to rotate. The output torque of the circumferential part 3212 is increased by utilizing the enlarged gear ratio. The circumferential part 3212 also has external teeth, which drive multiple transmission components 322. The transmission components 322 are also gears. Under the meshing action of the gears, the transmission components 322 rotate, thereby distributing the torque to multiple transmission components 322 to achieve the purpose of synchronously driving multiple adjusting components 33 to rotate.

[0034] In some embodiments of this application, the power unit 321 further includes an operation part 3214, which is installed on the power unit 3211 and used to operate the power unit 3211. The operation part 3214 can be manual or automatic. When the operation is manual, the operation part 3214 can be a knob or a crank.

[0035] In some embodiments of this application, the adjusting member 33 is provided with a guide portion 34, and the connecting member 42 is provided with a guide groove 44. The guide groove 44 is provided along the length direction of the connecting member 42. Since the guide portion 34 and the guide groove 44 are slidably engaged, the adjusting member 33 can drive the connecting member 42 to rotate. The mounting hole is a threaded hole, and the connecting member 42 is threadedly connected to the mounting hole. The power member 321 drives the transmission member 322 to move, and the transmission member 322 in turn drives multiple adjusting members 33 to rotate, so that the adjusting member 33 and the connecting member 42 are threadedly engaged, thereby causing the connecting member 42 to rotate within the adjusting member 33. The connecting member 42 can also be slidably connected to the support member 41. When the adjusting member 33 drives the connecting member 42 to rotate, since the connecting member 42 is threadedly engaged with the mounting hole, the connecting member 42 will slide relative to the support member 41, causing the connecting member 42 to screw into or out of the balance cylinder block.

[0036] For example, when the balance cylinder block needs to be disassembled, the connector 42 is slid to the contact mounting hole position, and the adjusting member 33 is rotated to one side to make the connector 42 engage with the mounting hole position, thereby causing the connector 42 to move into the mounting hole position. After the connector 42 abuts against the mounting block of the balance cylinder block, the connector 42 can continue to rotate. Due to the thread action, the balance cylinder block will slide towards the support member 41 side, thereby pushing the balance cylinder block out of the mounting block of the installation position, thus completing the disassembly of the balance cylinder block. When the balance cylinder block needs to be installed, the balance cylinder block is connected to multiple connectors 42, and the position is adjusted by the moving base 1 and the first drive mechanism 2 so that the balance cylinder block corresponds to the installation position in the archway. Then, the connector 42 is pushed so that the balance cylinder block is engaged with the mounting block of the installation position, so that the balance cylinder block fits the installation position. Then, the adjusting member 33 is driven to rotate to the other side, so that the connector 42 engages with the mounting hole position of the balance cylinder block in the opposite direction. Under the action of the reverse thrust, the connector 42 will slide out from the mounting hole position, thus completing the installation of the balance cylinder block.

[0037] In some embodiments of this application, the support member 41 includes a support portion 411 and a reinforcing portion 412 connected together; the support portion 411 is connected to the first drive mechanism 2, a plurality of connecting members 42 are slidably disposed on the support portion 411, and the second drive mechanism 3 is disposed on the support portion 411.

[0038] During implementation, the support part 411 is the main body of the support member 41. It is connected to the first drive mechanism 2 and serves as the support and installation body of the entire replacement mechanism 4. The reinforcing part 412 is set on the side of the support part 411 facing away from the balance cylinder block, which strengthens the main structure of the support part 411. The support part 411 and the first drive mechanism 2 can be detachably connected, which makes it easy to remove the entire first drive mechanism 2 for maintenance and repair. Multiple through parts 43 allow the connecting member 42 to pass through. On the one hand, they guide the sliding of the connecting member 42, and on the other hand, they provide auxiliary support for the connecting member 42, thereby enhancing the support effect of the connecting member 42 on the balance cylinder block.

[0039] In some embodiments of this application, the first driving mechanism 2 includes a guide 21 and a driving member 22. The guide 21 is disposed on the movable base 1, and the support member 41 has a guide groove. The guide 21 is slidably engaged with the guide groove. The driving member 22 is disposed on the movable base 1 and is connected to the support member 41 to drive the support member 41 to slide along a first direction.

[0040] During implementation, the guide member 21 is supported by the movable base 1. The guide groove can be set on the reinforcing part 412 of the support frame. The cross-sectional thickness of the support member 41 at the reinforcing part 412 is large, which can better withstand the torque. The guide member 21 slides with the guide groove and the sliding direction is the first direction, which restricts the movement direction of the support member 41. After the support frame is equipped with the balance cylinder block, the guide member 21 forms a limit through the restriction, which increases the load-bearing capacity and shares the lateral load on the drive member 22. The drive member 22 is the power part 3211 that realizes the sliding of the support member 41. The drive member 22 can be a hydraulic cylinder / pneumatic cylinder or an electric push rod. The drive member 22 needs to be able to bear the weight of the balance cylinder block. The drive member 22 can control the sliding position of the support member 41, and then correspond to the installation position of the balance cylinder block to carry out the disassembly and assembly of the balance cylinder block.

[0041] For some embodiments of this application, please refer to the appendix to the specification. Figure 6 The balance cylinder block disassembly and assembly device also includes a construction platform 5, which is used to insert into the rolling mill. The rolling mill has a roll changing track. The construction platform 5 is slidably set on the roll changing track, and the movable base 1 is slidably set on the construction platform 5. During implementation, the construction platform 5 is first pushed into the rolling mill. The construction platform 5 has its own positioning rollers and moves by being pushed and pulled by the roll changing trolley. One side of the positioning rollers is a V-shaped positioning roller 51 to prevent the construction platform 5 from deviating during the operation and to ensure the accuracy of movement. With the help of the rolling mill roll changing track (common roll changing tracks have a locking position that matches the V-shaped positioning roller 51) and the mutual limiting of the positioning rollers, a stable operating platform is provided for the construction personnel, making the construction personnel safer to work inside the rolling mill. Moreover, the construction platform 5 moves by being pushed and pulled by the roll changing trolley. During use, the balance cylinder block can be disassembled multiple times. By pushing and pulling the construction platform 5 with the roll changing trolley, the balance cylinder block can be taken out in one go without manual pushing and pulling, which is more convenient and labor-saving.

[0042] In other embodiments of this application, a method for disassembling and assembling a balance cylinder block is also disclosed, implemented based on the aforementioned balance cylinder block disassembly and assembly device. The method includes: Step S100: Equipment arrival and construction platform positioning. Step S110: Push the construction platform into the mill maintenance space, and use its V-shaped positioning rollers to cooperate with the locking position of the mill roll changing track. The roll changing trolley pulls the platform to achieve precise positioning, prevent the platform from shifting, and ensure construction safety.

[0043] Step S120: The mobile base slides into the mill along the construction platform. The direction of the mobile chassis is controlled by adjusting the handle so that the mobile base is close to the installation position of the balance cylinder block. At this time, the load-bearing rollers distribute the weight of the equipment to ensure load-bearing stability.

[0044] Step S200: The first drive mechanism positions and replaces the mechanism.

[0045] Step S210: Start the drive component of the first drive mechanism. Through the sliding cooperation between the guide component and the guide groove of the reinforcing part, control the support component to slide in a direction perpendicular to the moving surface of the moving base, so that the replacement mechanism is initially aligned with the installation area of ​​the balance cylinder block.

[0046] Step S220: Based on the specific mounting hole positions of the balance cylinder block, fine-tune the output of the drive component, and ensure the accurate sliding direction of the support component through the limiting effect of the guide component to avoid deviation affecting the subsequent connection accuracy.

[0047] Step S300: The second replacement mechanism adjusts the connection between the replacement mechanism and the balance cylinder block.

[0048] Step S310: After the support of the replacement mechanism slides to the vicinity of the balance cylinder block, the guide part in the adjusting part slides into the guide groove of the connecting part, so that the connecting part slides along the through part toward the mounting hole of the balance cylinder block.

[0049] Step S320: When the connector contacts the threaded mounting hole of the balance cylinder block, the power component of the second drive mechanism drives multiple adjusting components to rotate synchronously. The connector is screwed into the mounting hole by thread engagement until the connector and the balance cylinder block form a stable and detachable connection. At this time, the support component provides auxiliary support for the connector through the through part to enhance the connection stability.

[0050] Step S400: Balance block disassembly or installation operation.

[0051] Step S410: When disassembling the balance cylinder block, after the connector is fully screwed into the mounting hole, the second drive mechanism rotates the adjusting component in the forward direction. The connector engages with the mounting hole of the balance cylinder block and moves into the balance cylinder block. When the connector contacts the mounting block on the archway, the connector continues to rotate. Under the action of the thread, it applies a pushing force to the balance cylinder block, pushing the balance cylinder block out of the archway mounting block. At this time, the movable base supports the weight of the balance cylinder block, completing the disassembly.

[0052] Step S420: When installing the balance cylinder block, after connecting the balance cylinder block to be installed through the connector, move the base and adjust the position in coordination with the first drive mechanism so that the balance cylinder block is aligned with the archway installation position. Push the connector to make the balance cylinder block snap into the installation block. Then, the second drive mechanism rotates the adjusting component in the opposite direction so that the connector is screwed out from the installation hole to complete the installation.

[0053] Step S500: Equipment exit and balance block transport.

[0054] Step S510: After disassembly, the movable base carries the disassembled balance cylinder block and slides out of the mill maintenance space along the construction platform. The balance cylinder block is transported to the designated storage area by the cooperation of the positioning rollers of the construction platform and the roll changing track.

[0055] Step S520: After installation, once the balance cylinder block is confirmed to be in place, the moving base is removed from the rolling mill, and the construction platform is moved out by the roll changing trolley, completing the entire disassembly and assembly process. At this time, all parts of the equipment can be disassembled for maintenance, ensuring the reliability of subsequent use.
