[0025] Please see Figures 1-4 As shown, this utility model provides a technical solution:

[0026] A spindle lifting device for a vertical rolling mill includes:

[0027] A horizontal plate 1 is provided. U-shaped plates 2 are fixedly installed on both sides of the horizontal plate 1. Fixing plates 4 are fixedly installed inside the two U-shaped plates 2. Two connecting plates 6 are provided on one side of each of the two fixing plates 4. Fixing blocks 5 are fixedly installed on one side of each fixing plate 4. One end of the fixing blocks 5 passes through the two connecting plates 6 and extends to the outside. Mounting plates 8 are fixedly installed on the top of each of the two connecting plates 6. Clamps 7 are fixedly installed on the bottom of each of the two connecting plates 6. Rotary wheels 13 are provided on the front side of each of the two mounting plates 8. Round blocks 10 are provided on the side of each of the two mounting plates 8 that are far apart from each other. A sliding rod 11 is fixedly installed on one side of the inner wall of the U-shaped plate 2. One end of the sliding rod 11 passes through the two round blocks 10 and the two mounting plates 8 and is fixed to the other side of the inner wall of the U-shaped plate 2.

[0028] Two springs 9 are mounted on the slide bar 11, and the two springs 9 are located on opposite sides of the circular block 10.

[0029] Two electric push rods 3 are fixedly installed on the top of two U-shaped plates 2 respectively. The output end of the electric push rod 3 passes through the U-shaped plate 2 and is provided with a protrusion 12. The protrusion 12 is located between two rotating wheels 13. A circular ring 14 is fixedly installed on the top of each of the two U-shaped plates 2. The two circular rings 14 are located on one side of the two electric push rods 3 respectively. Through the cooperation of the horizontal plate 1, U-shaped plate 2, electric push rod 3, fixed plate 4, fixed block 5, connecting plate 6, clamp 7, mounting plate 8, spring 9, circular block 10, sliding rod 11, protrusion 12, rotating wheel 13 and circular ring 14, this device adopts an adjustable structural design, which can adjust the lifting height and force according to actual needs, thereby adapting to the rolling requirements of steel plates of different specifications and materials. This improvement not only enhances the flexibility of the device, but also significantly enhances its adaptability and market competitiveness.

[0030] In this embodiment, the fixing block 5 is rotatably connected to the connecting plate 6 to ensure that the fixing block 5 can rotate normally on the connecting plate 6.

[0031] In this embodiment, the slide rod 11 is slidably connected to the circular block 10 and to the mounting plate 8, ensuring that the slide rod 11 can slide normally on the circular block 10 and that the slide rod 11 can slide normally within the mounting plate 8.

[0032] In this embodiment, the slide rod 11 is tightly welded to the U-shaped plate 2, and the output end of the electric push rod 3 is slidably connected to the U-shaped plate 2 to ensure the structural stability of the slide rod 11 and the U-shaped plate 2, and to ensure that the output end of the electric push rod 3 can slide normally on the U-shaped plate 2.

[0033] In this embodiment, the output end of the electric push rod 3 is tightly welded to the protrusion 12 to ensure the structural stability of the output end of the electric push rod 3 and the protrusion 12.

[0034] In this embodiment, the surface of the clamp 7 is provided with anti-slip texture to ensure that the clamp 7 has a large friction force during the clamping process.

[0035] In this embodiment, the two ends of the spring 9 are tightly welded to the circular block 10 and the U-shaped plate 2 respectively, to ensure the structural stability of the spring 9, the circular block 10 and the U-shaped plate 2.

[0036] In this embodiment, the vertical roll mill spindle lifting device is first connected to two rings 14 on the top of the device via hooks on the overhead crane, suspending and fixing the entire lifting device. At this time, the overhead crane can be adjusted to move the entire device directly above the vertical roll mill spindle, preparing for subsequent spindle clamping operations. This process utilizes the load-bearing capacity of the rings 14 to ensure the device remains stable during movement and lifting.

[0037] After the device moves to the main shaft clamping position, the electric push rods 3 on the top of the two U-shaped plates 2 are activated. The output end of the electric push rod 3 extends downward, driving the protrusion 12 to move down. Since the protrusion 12 is located between the two rotating wheels 13, the downward-moving protrusion 12 will exert a squeezing force on the rotating wheels 13 on both sides. Because the mounting plate 8 is rotatably connected to the rotating wheels 13, the rotating wheels 13 will push the two mounting plates 8 to slide away from each other along the slide rod 11 after being subjected to force. At the same time, the mounting plate 8 drives the round block 10 to slide synchronously. During this process, the round block 10 will compress the spring 9 on its outer side, so that the spring 9 stores elastic potential energy. Since the mounting plate 8 is fixedly connected to the connecting plate 6, the sliding of the mounting plate 8 will drive the connecting plate 6 to rotate around the fixed block 5 as the fulcrum, and finally make the two clamps 7 at the bottom of the connecting plate 6 move away from each other, realizing the opening action of the clamps 7.

[0038] While clamp 7 remains open, the height of the overhead crane adjusting device is used to position the main shaft of the vertical rolling mill to be lifted between the two clamps 7, completing the alignment operation between the main shaft and clamp 7. During this stage, it is essential to ensure that the main shaft is within the clamping range of clamp 7, providing a foundation for subsequent clamping actions.

[0039] After the main shaft is aligned, the output end of the control electric push rod 3 retracts upward, and the protrusion 12 moves upward accordingly, relieving the squeezing force on the roller 13. At this time, the compressed spring 9 releases its elastic potential energy, pushing the round block 10 to slide along the slide rod 11 towards each other. The round block 10 drives the mounting plate 8 to move synchronously. When the mounting plate 8 moves, it drives the connecting plate 6 to rotate again around the fixed block 5 as the fulcrum, so that the two clamps 7 move closer to each other. Since the surface of the clamp 7 is provided with anti-slip texture, it can finally clamp the main shaft of the vertical roll mill tightly, preventing the main shaft from slipping during the lifting process. This device adopts an adjustable structural design, which can adjust the lifting height and force according to actual needs, thereby adapting to the rolling requirements of steel plates of different specifications and materials. This improvement not only enhances the flexibility of the device, but also significantly enhances its adaptability and market competitiveness.

[0040] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments.
