Description

Technical Field

[0001] This invention relates to the technical field of continuous casting machine crystallizer maintenance equipment, specifically a maintenance platform for a hydraulic servo vibration device of a continuous casting machine crystallizer. Background Technology

[0002] As the core equipment in continuous casting production, the hydraulic servo vibration device of the continuous casting machine crystallizer directly affects the surface quality of the cast billet and the continuity of production. After long-term operation, the vibration device is prone to failures such as component wear and accuracy deviation, and needs to be disassembled, repaired or replaced regularly.

[0003] In existing maintenance processes, vibration devices are large in size and heavy in weight. Traditional hoisting methods rely on manual labor and simple hoisting tools, which makes it inconvenient to adjust the position during hoisting. Uneven force can easily cause collision damage to the components, and it is difficult to install them accurately. Moreover, there is a lack of dedicated lifting mechanisms. During maintenance, a support platform needs to be built manually, which has low height adjustment accuracy and cannot meet the height requirements of different maintenance procedures. The operation is cumbersome and has poor safety. Summary of the Invention

[0004] In view of the shortcomings of the prior art, the main objective of this invention is to provide a maintenance platform for the hydraulic servo vibration device of the continuous casting machine crystallizer, so as to solve the problems of low hoisting accuracy and poor adjustment flexibility of the existing maintenance equipment mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a maintenance platform for a hydraulic servo vibration device of a continuous casting machine crystallizer, comprising: a repair frame, a support column fixedly connected to the upper surface of the repair frame, a top plate fixedly connected to the upper surface of the support column, a lifting mechanism and a clamping mechanism provided on the upper surface of the repair frame, the lifting mechanism including a placement plate fixedly connected to the upper surface of the repair frame, two pairs of first fixing plates fixedly connected to the upper surface of the placement plate, a pair of first rotating shafts rotatably connected to the two pairs of first fixing plates, and two pairs of first connecting rods rotatably connected to the pair of first rotating shafts. The first connecting rod is rotatably connected to two pairs of second rotating shafts, which are rotatably connected to two pairs of second connecting rods. The two pairs of second connecting rods are rotatably connected to a third rotating shaft. The third rotating shaft is rotatably connected to two pairs of second fixed plates. A placement platform is fixedly connected to the upper surface of the two pairs of second fixed plates. A guide plate is provided on the upper surface of the placement plate. A pair of first slide rails is fixedly connected inside the guide plate. A slider is slidably connected to the outer wall of the first slide rails. A pair of second air pumps is fixedly connected to the upper surface of the placement plate. A pair of second air rods are fixedly connected to the upper surface of the pair of second air pumps. The clamping mechanism includes a pair of connecting plates fixedly connected to the upper surface of the placement platform. A pair of first guide rods are slidably connected to the pair of connecting plates. A first air pump is fixedly connected to one side of the connecting plates. A first air rod is fixedly connected to one side of the first air pump. A clamping plate is fixedly connected to one side of the first air rod.

[0006] As a further improvement of the present invention, one side of the slider is connected to one side of the second rotating shaft, and one side of the pair of first guide rods is connected to one side of the clamping plate.

[0007] As a further improvement of the present invention, the lower surface of the top plate is also provided with an adjustment mechanism, the adjustment mechanism including a pair of second slide rails fixedly connected to the lower surface of the top plate, a third air pump fixedly connected to the lower surface of the top plate, a third air rod fixedly connected to one side of the third air pump, and a sliding plate fixedly connected to one side of the third air rod.

[0008] As a further improvement of the present invention, the outer wall of the second slide rail is slidably connected to the inside of the slide plate.

[0009] As a further improvement of the present invention, the lower surface of the sliding plate is also provided with a hoisting mechanism. The hoisting mechanism includes a first adjusting frame fixedly connected to the lower surface of the sliding plate. The first adjusting frame is rotatably connected to an adjusting shaft. The adjusting shaft is rotatably connected to a pair of connecting blocks. The lower surface of the pair of connecting blocks is fixedly connected to a second adjusting frame. The second adjusting frame is rotatably connected to a connecting shaft. The connecting shaft is rotatably connected to a pair of arc-shaped lifting rods.

[0010] The beneficial effects of this invention are as follows: This invention, through the setting of an adjustment mechanism, uses a third air pump to drive the extension and retraction of a third air rod, which in turn moves the sliding plate and the lower hoisting mechanism smoothly along the second slide rail. This allows for precise adjustment of the horizontal position of the hoisting mechanism, achieving accurate alignment between the vibration device and the maintenance station and assembly reference. This avoids damage to components due to positional deviations caused by manual hoisting. Through the hoisting mechanism, the first adjustment frame and the adjustment shaft work together to finely adjust the installation angle of the connecting block, adapting to the hoisting requirements of different parts of the vibration device. The second adjustment frame, the connecting shaft, and the arc-shaped lifting rod form a flexible hoisting structure. The arc-shaped lifting rod fits against the outer wall of the vibration device, increasing the contact area, dispersing hoisting stress, and preventing excessive local stress from causing component deformation.

[0011] With the lifting mechanism, the second air pump drives the second air rod to extend and retract, and the slider slides along the first slide rail, causing the scissor structure to unfold or retract, realizing the vertical lifting and lowering of the placement platform. The height of the vibration device can be flexibly adjusted according to the maintenance procedure, replacing the manual construction of the support platform. With the clamping mechanism, the first air pump drives the first air rod to extend and retract, causing the clamping plate to flexibly clamp the vibration device, avoiding excessive clamping force that could cause scratches or deformation on the surface of the parts.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0015] In one embodiment, see Figure 1-3The present invention discloses a maintenance platform for a hydraulic servo vibration device of a continuous casting machine crystallizer, comprising: a repair frame 1, a support column 2 fixedly connected to the upper surface of the repair frame 1, a top plate 3 fixedly connected to the upper surface of the support column 2, a lifting mechanism and a clamping mechanism provided on the upper surface of the repair frame 1, the lifting mechanism comprising a placement plate 4, a first fixed plate 5, a first rotating shaft 6, a first connecting rod 7, a second rotating shaft 8, a second connecting rod 9, a third rotating shaft 10, a second fixed plate 11, a placement platform 12, a guide plate 18, a first slide rail 19, a slider 20, a second air pump 21, and a second air rod 22; the upper surface of the repair frame 1 is fixedly connected to the placement plate 4, two pairs of first fixed plates 5 are fixedly connected to the upper surface of the placement plate 4, and a pair of first rotating shafts 6 are rotatably connected to one side of each pair of first fixed plates 5; the pair of first rotating shafts 6... Two pairs of first connecting rods 7 are rotatably connected to the outer wall. Two pairs of second rotating shafts 8 are rotatably connected inside the two pairs of first connecting rods 7. Two pairs of second connecting rods 9 are rotatably connected inside the two pairs of second rotating shafts 8. A third rotating shaft 10 is rotatably connected to the outer wall of the two pairs of second connecting rods 9. A second fixed plate 11 is rotatably connected to one side of the third rotating shaft 10. A placement platform 12 is fixedly connected to the upper surface of the two pairs of second fixed plates 11. A guide plate 18 is provided on the upper surface of the placement plate 4. A pair of first slide rails 19 are fixedly connected inside the guide plate 18. A slider 20 is slidably connected to the outer wall of the first slide rails 19. A pair of second air pumps 21 are fixedly connected to the upper surface of the placement plate 4. A pair of second air rods 22 are fixedly connected to the output end of the pair of second air pumps 21. One side of the slider 20 is rotatably connected to one side of the second rotating shaft 8. The second air pump 21 outputs power to drive the second air rod 22 to extend and retract, causing the slider 20 to slide along the first slide rail 19, which in turn links the scissor structure composed of the first rotating shaft 6, the first connecting rod 7, the second rotating shaft 8, the second connecting rod 9, and the third rotating shaft 10 to extend or retract, thereby realizing the vertical lifting and lowering of the placement platform 12 and the vibration device clamped above it.

[0016] Furthermore, such as Figure 2 As shown, the clamping mechanism includes a connecting plate 13, a first guide rod 14, a first air pump 15, a first air rod 16, and a clamping plate 17. A pair of connecting plates 13 are fixedly connected to the upper surface of the placement platform 12. A pair of first guide rods 14 are slidably connected to the pair of connecting plates 13. A first air pump 15 is fixedly connected to one side of the connecting plate 13. A first air rod 16 is fixedly connected to one side of the first air pump 15. A clamping plate 17 is fixedly connected to one side of the first air rod 16. One side of the pair of first guide rods 14 is connected to one side of the clamping plate 17. The output from the first air pump 15 is transmitted to the clamping plate 17 via the first air rod 16, driving the two clamping plates 17 to move relative to or in opposite directions, thereby achieving precise positioning and stable clamping of the hydraulic servo vibration device of the continuous casting machine crystallizer on the placement platform 12.

[0017] Furthermore, such as Figure 3 As shown, an adjustment mechanism is also provided on the lower surface of the top plate 3. The adjustment mechanism includes a second slide rail 23, a third air pump 24, a third air rod 25 and a sliding plate 26. A pair of second slide rails 23 are fixedly connected to the lower surface of the top plate 3. A third air pump 24 is fixedly connected to the lower surface of the top plate 3. A third air rod 25 is fixedly connected to one side of the third air pump 24. A sliding plate 26 is fixedly connected to one side of the third air rod 25. The outer wall of the second slide rail 23 is slidably connected to the inside of the sliding plate 26. The air output from the third air pump 24 is transmitted to the sliding plate 26 via the third air rod 25, driving the sliding plate 26 to move horizontally and linearly along the second slide rail 23, thereby driving the lower hoisting mechanism to move synchronously and achieve precise lateral adjustment of the hoisting position.

[0018] Furthermore, such as Figure 3 As shown, a hoisting mechanism is also provided on the lower surface of the sliding plate 26. The hoisting mechanism includes a first adjusting frame 27, an adjusting shaft 28, a connecting block 29, a second adjusting frame 30, a connecting shaft 31, and an arc-shaped lifting rod 32. The first adjusting frame 27 is fixedly connected to the lower surface of the sliding plate 26. The adjusting shaft 28 is rotatably connected inside the first adjusting frame 27. A pair of connecting blocks 29 are rotatably connected to the outer wall of the adjusting shaft 28. The second adjusting frame 30 is fixedly connected to the lower surface of the pair of connecting blocks 29. The connecting shaft 31 is rotatably connected inside the second adjusting frame 30. A pair of arc-shaped lifting rods 32 are rotatably connected to the connecting shaft 31. The first adjusting frame 27 and the adjusting shaft 28 work together to achieve fine adjustment of the horizontal angle, and the second adjusting frame 30 and the connecting shaft 31 drive the arc-shaped lifting rod 32 to achieve adaptive adjustment of the clamping angle.

[0019] When using this invention, the operator moves the hydraulic servo vibration device to be repaired to the side of the repair frame 1, the hoisting mechanism is started, the arc-shaped lifting rod 32 rotates and opens around the connecting shaft 31 under its own weight, and fits against the outer wall of the vibration device. The first adjusting frame 27 and the adjusting shaft 28 finely adjust the horizontal angle so that the arc-shaped lifting rod 32 is completely adapted to the lifting point position of the vibration device, and the inner rubber pad tightly fits against the surface of the component to form a stable clamp. The third air pump 24 of the adjustment mechanism is started, and the output power is transmitted to the sliding plate 26 through the third air rod 25, driving the sliding plate 26 to move horizontally along the second slide rail 23, which drives the hoisting mechanism and the vibration device to move synchronously until the center of the vibration device is aligned with the center of the lifting mechanism placement platform 12, thus completing the lateral alignment. The vibration device is slowly lowered above the placement platform 12. The second air pump 21 of the lifting mechanism is started, driving the second air rod 22 to extend and retract, causing the slider 20 to slide along the first slide rail 19. The scissor structure composed of the first connecting rod 7 and the second connecting rod 9 slowly unfolds, and the placement platform 12 rises vertically until the surface of the placement platform 12 contacts the bottom of the vibration device, completing the stable support and avoiding hard impact that could damage the components. The first air pump 15 of the clamping mechanism is started, and the output power is transmitted to the clamping plate 17 through the first air rod 16. The clamping plate 17 moves along the first guide rod 14 towards the vibrating device. If the side parts of the vibrating device need to be repaired, the adjustment mechanism drives the hoisting mechanism to move and reset, making room for operation. The lifting mechanism can finely adjust the height of the placement platform 12 to suit the operating view of the maintenance personnel. If the bottom parts need to be repaired, the lifting mechanism drives the placement platform 12 to a high position, making it convenient for maintenance personnel to work from below. If the angle of the vibrating device needs to be adjusted, the clamping mechanism is loosened appropriately, the hoisting mechanism re-clamps and cooperates with manual fine-tuning of the angle, the lifting mechanism provides auxiliary support, and the clamping mechanism is tightened again after the adjustment is completed. After the vibration device is repaired, the first air pump 15 of the clamping mechanism exhausts air in reverse, the first air rod 16 retracts, the clamping plate 17 moves away from the vibration device, the release component is released, the scissor structure of the lifting mechanism retracts, the placement platform 12 is lowered to the lowest height to provide space for the hoisting mechanism to unload the material, the arc-shaped lifting rod 32 of the hoisting mechanism is once again attached to the vibration device and clamped, the adjusting mechanism drives the sliding plate 26 to move horizontally, and the vibration device is transferred to the storage position outside the repair area, or handed over to external hoisting equipment, thus completing the entire repair process.
