Description

Technical Field

[0001] This utility model relates to the field of work roll unloading frame technology, specifically a work roll unloading frame. Background Technology

[0002] Hot rolling is an important process in the production of strip steel in modern steel plants. During the hot rolling process, the mill needs to be stopped once for a roll change operation after each batch of slabs is rolled. In the production of hot-rolled strip steel, the work rolls of the finishing mill need to be changed frequently (3-4 times per shift). The roll change efficiency directly affects the output and cost of the production line.

[0003] Traditional work roll storage and transfer usually rely on simple frames. The work rolls are simply placed on the frame without a fixing mechanism. When moving or picking up the rolls, the axial displacement can easily cause the roll body to shake and collide, resulting in scratches on the roll surface or deformation of the journal, which affects the subsequent rolling accuracy. At the same time, manual assistance is required to align and fix the work rolls when picking them up or picking them up. This is not compatible with the high efficiency requirements of modern fully automatic roll changing systems, which prolongs non-production time and restricts the improvement of rolling line efficiency.

[0004] In view of this, we propose a working roll release frame. Summary of the Invention

[0005] The purpose of this utility model is to provide a work roll unloading frame to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A work roll unloading frame, comprising:

[0008] The main frame has several roll-laying frames fixedly installed from top to bottom. Each roll-laying frame has an installation groove on its top. The top of each roll-laying frame and the left and right sides of the installation groove have corresponding work roll shaft placement grooves. Several work roll bodies are fixedly installed in the installation grooves. The two output shafts of each work roll body are located in the corresponding work roll shaft placement grooves. The inner wall of the roll-laying frame has symmetrical sliding grooves. A sliding plate is symmetrically slidably installed between two sliding grooves. The bottom of the sliding plate has a work roll shaft clamping groove corresponding to the several work roll shaft placement grooves.

[0009] A drive assembly located on the roll release frame and used to drive two slide plates toward or away from each other.

[0010] Preferably, the driving component includes:

[0011] A bidirectional threaded rod is rotatably installed in one of the slide grooves. One end of the bidirectional threaded rod passes through two slide plates. A motor is fixedly installed on one side of the roll release frame. The output end of the motor passes through one side of the roll release frame, extends into one of the slide grooves, and is coaxially connected to the bidirectional threaded rod.

[0012] Preferably, the output shaft of the motor is rotatably connected to the roll unloading frame, and both slide plates are threadedly connected to a bidirectional threaded rod.

[0013] Preferably, electric actuators are fixedly installed on both the left and right sides of the main frame, and support plates are fixedly installed on the top of each of the two electric actuators. The output end of the support plate passes through the top of the electric actuator and is fixedly installed with a lifting plate. An anti-slip pad is fixedly installed on the bottom of the lifting plate, and the output shaft of the support plate is slidably connected to the electric actuator.

[0014] Preferably, casters are fixedly installed at the bottom of the main frame and at the four corners, and handrails are fixedly installed at the rear of the main frame.

[0015] Preferably, reinforcing ribs that are fixed to the inner wall of the main frame are fixedly installed at the bottom of several of the roller release frames and near the four corners.

[0016] Preferably, the size of the working roller shaft clamping groove is adapted to the size of the working roller shaft placement groove.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] This work roll placement frame, through the cooperation of the placement frame, mounting groove, work roll shaft placement groove, slide groove, sliding plate, work roll shaft clamping groove, reinforcing rib, and drive assembly, uses a motor-driven bidirectional threaded rod to slide the sliding plate, so that the work roll shaft clamping groove and the work roll shaft placement groove are precisely closed, tightly clamping the work roll shaft journal axially, avoiding displacement or slippage during movement or storage, reducing the risk of roll surface damage, and ensuring the accuracy of the work roll. At the same time, the automated clamping mechanism reduces the operation time of manual alignment and fixing, matching the speed requirements of the fully automatic roll changing system of the finishing mill, and indirectly shortening non-production time.

[0027] Please see Figures 1-5 As shown, this utility model provides a technical solution:

[0028] A work roll unloading frame, comprising:

[0029] The main frame 1 contains several roll-laying frames 2 fixedly installed from top to bottom. Each roll-laying frame 2 has a mounting groove 3 on its top. Corresponding work roller shaft placement grooves 4 are located on the top of each roll-laying frame 2 and on the left and right sides of the mounting groove 3. Several work roller bodies 17 are fixedly installed in the mounting grooves 3, with their two output shafts located within their respective work roller shaft placement grooves 4. Sliding grooves 5 are symmetrically provided on the inner wall of each roll-laying frame 2. Sliding plates 8 are symmetrically slidably installed between two sliding grooves 5. The bottom of each sliding plate 8 has a work roller shaft clamping groove 9 corresponding to the work roller shaft placement grooves 4. A drive assembly is located on the roll-laying frame 2 and is used to drive the two sliding plates 8 to move closer or further apart. When it is necessary to place a work roller body 17, the work roller body 17 is placed on the target placement groove. Above the roller frame 2, align the roller body with the mounting groove 3, and align the journals at both ends with the corresponding working roller shaft placement grooves 4. Slowly lower the working roller, ensuring that the journals are fully embedded in the working roller shaft placement grooves 4. The roller body falls smoothly into the mounting groove 3. Drive the two slide plates 8 to move through the drive assembly. At this time, the two slide plates 8 slide along the slide groove 5 to both sides. The working roller shaft clamping groove 9 and the working roller shaft placement groove 4 approach each other. At this time, the working roller shaft clamping groove 9 at the bottom of the slide plate 8 and the working roller shaft placement groove 4 are completely closed, and the journal of the working roller body 17 is tightly clamped, thereby completing the fixation of the working roller body 17. When the working roller body 17 needs to be used, drive the slide plates 8 to slide to both sides again through the drive assembly. The working roller shaft clamping groove 9 and the working roller shaft placement groove 4 separate, releasing the working roller body 17 for easy access.

[0030] In this embodiment, the driving component includes:

[0031] A bidirectional threaded rod 6 is rotatably mounted in one of the slide grooves 5. One end of the bidirectional threaded rod 6 passes through two slide plates 8. A motor 7 is fixedly mounted on one side of the roller placement frame 2. The output end of the motor 7 extends through one side of the roller placement frame 2 into one of the slide grooves 5 and is coaxially connected to the bidirectional threaded rod 6. When the motor 7 is powered on and started, the output shaft of the motor 7 rotates, driving the bidirectional threaded rod 6 to rotate. Under the action of the thread, the rotating bidirectional threaded rod 6 drives the two slide plates 8 to move, thereby causing the working roller shaft clamping groove 9 and the working roller shaft placement groove 4 to move closer or further apart.

[0032] In this embodiment, the output shaft of the motor 7 is rotatably connected to the roll release frame 2, and both slide plates 8 are threadedly connected to the bidirectional threaded rod 6, ensuring that the motor 7 can operate normally on the roll release frame 2. Under the action of the thread, the rotating bidirectional threaded rod 6 drives the two slide plates 8 to move.

[0033] In this embodiment, electric push rods 11 are fixedly installed on both the left and right sides of the main frame 1. Support plates 12 are fixedly installed on the top of the two electric push rods 11. The output end of the support plate 12 passes through the top of the electric push rod 11 and is fixedly installed with a lifting plate 13. An anti-slip pad 14 is fixedly installed at the bottom of the lifting plate 13. The output shaft of the support plate 12 is slidably connected to the electric push rod 11. When the electric push rods 11 on both sides of the main frame 1 are activated, the output end of the electric push rod 11 pushes the support plate 12 to drive the lifting plate 13 down until the anti-slip pad 14 is in close contact with the ground, ensuring that the entire device is fixed on the ground.

[0034] In this embodiment, casters 15 are fixedly installed at the bottom of the main frame 1 and at the four corners. Handrails 16 are fixedly installed at the rear of the main frame 1. By pushing the handrails 16, the entire device can be moved to the target area via the casters 15.

[0035] In this embodiment, reinforcing ribs 10, which are fixed to the inner wall of the main frame 1, are fixedly installed at the bottom of several roll release frames 2 and near the four corners. The reinforcing ribs 10 enhance the load-bearing capacity of the roll release frames 2 and prevent deformation.

[0036] In this embodiment, the working roller shaft clamping groove 9 is matched with the working roller shaft placement groove 4 in size, ensuring that the journal of the working roller body 17 is tightly clamped, avoiding axial displacement and shaking during placement or movement, and improving the fixing stability.

[0037] In this embodiment, when a working roller release frame is in use, the handle 16 is pushed and the pile device is moved to the target area via the casters 15. The electric push rods 11 on both sides of the main frame 1 are activated. The output end of the electric push rod 11 pushes the support plate 12 to drive the lifting plate 13 down until the anti-slip pad 14 is in close contact with the ground, ensuring that the entire device is fixed to the ground.

[0038] When it is necessary to place the work roll body 17, place the work roll body 17 above the target roll placement frame 2, align the roll body with the mounting groove 3, and align the journals at both ends with the corresponding work roll shaft placement grooves 4. Slowly lower the work roll, ensuring that the journals are fully embedded in the work roll shaft placement grooves 4, and the roll body falls smoothly into the mounting groove 3. The reinforcing ribs 10 enhance the load-bearing capacity of the roll placement frame 2 and prevent deformation. Connect the power supply to the motor 7 on one of the roll placement frames 2 and start it. The output shaft of the motor 7 rotates, driving the bidirectional threaded rod 6 to rotate. Under the action of the thread, the rotating bidirectional threaded rod 6 drives the two slide plates 8 to move. At this time, the two slide plates 8 slide along the slide groove 5 to both sides, and the working roller shaft clamping groove 9 and the working roller shaft placement groove 4 approach each other. At this time, the working roller shaft clamping groove 9 and the working roller shaft placement groove 4 at the bottom of the slide plate 8 are completely closed, and the journal of the working roller body 17 is tightly clamped, thereby completing the fixation of the working roller body 17. When the working roller body 17 needs to be used, the motor 7 is started again, the output shaft of the motor 7 rotates in the opposite direction, and the bidirectional threaded rod 6 drives the slide plate 8 to slide to both sides, the working roller shaft clamping groove 9 separates from the working roller shaft placement groove 4, and the working roller body 17 is released, making it convenient to take out the working roller body 17.
