[0001] The present invention relates to the technical field of flange production, in particular to a device for producing wind power tower flanges by continuously casting large round billets. Background Art

[0002] At a time when the new energy industry is booming, wind power, as an important component of clean energy, has attracted much attention in the production and manufacturing of its core component, wind turbine towers. Wind turbine tower flanges are key components that connect the various sections of the tower. In the production of continuous casting large round billets, the lifting process is an essential and important step. It runs through multiple stages of flange production, from the transportation of raw materials to the transportation after processing and forming. The accuracy and stability of lifting directly affect the continuity of the production process and product quality. Regarding the above-mentioned related technologies, the inventor believes that the current traditional wind turbine tower flange lifting devices have many problems in practical applications. Most lifting devices have simple structural designs, and the flange fixing effect is poor during the lifting process.

As a result, the flange is prone to shaking, tilting, or even falling off due to uneven force during lifting, posing serious safety hazards. At the same time, the lack of safety protection measures means that once the structure has loose or broken components, it is very likely to cause safety accidents, and it is impossible to provide reliable safety guarantees for lifting operations. Therefore, a device for continuously casting large round billets to produce wind turbine tower flanges is proposed to solve the above problems.

[0016] The following is combined with Figure 1 - Figure 6 The present invention application is described in further detail.

[0017] A device for continuously casting large round billets to produce wind turbine tower flanges includes a gantry frame 1, a fixed ring 8, and a stabilizing component installed on the fixed ring 8. An electric hoist 2 is slidably installed on the outer wall of the gantry frame 1, and a hook 6 is fixedly installed on the outer wall of the electric hoist 2. The hook 6 is used to connect other components to realize the lifting function. The electric hoist 2 slides on the gantry frame 1, and the position of the hook 6 can be flexibly adjusted to meet the lifting requirements of the wind turbine tower flange under different working conditions. A connecting cover 7 is provided between the hook 6 and the fixed ring 8. The outer wall of the fixed ring 8 is fixedly connected to a base frame 18, and the base frame 18 provides an installation foundation for other components. The outer wall of the base frame 18 is fixedly connected to a sliding column 11, and the outer wall of the sliding column 11 is slidably connected to a sliding sleeve 9. The sliding sleeve 9 can slide along the sliding column 11. It slides up and down, and a plurality of support rods 10 are provided between the sliding sleeve 9 and the connecting cover 7. The two ends of the plurality of support rods 10 are fixedly connected to the connecting cover 7 and the sliding sleeve 9. The support rods 10 play the role of supporting and stabilizing the connecting cover 7 and the sliding sleeve 9. When the hook 6 is connected to the connecting cover 7, the electric hoist 2 drives the hook 6 to move up, so that the hook 6 drives the connecting cover 7 to move up synchronously, and then the connecting cover 7 drives the sliding sleeve 9 to move up synchronously through the plurality of support rods 10, so as to ensure the stability and fixation of the subsequent flange lifting. The gantry frame 1, electric hoist 2, hook 6, connecting cover 7, fixing ring 8, base frame 18, sliding column 11, sliding sleeve 9 and support rods 10 cooperate with each other to build a stable lifting infrastructure. The stabilizing assembly includes a plurality of external fixing blocks 23. The outer wall of the fixing ring 8 is provided with a plurality of external grooves 22 in a circumferential array, and the plurality of external fixing blocks 23 are rotatably connected to the plurality of external grooves 22 so that the external fixing blocks 23 can rotate around the connection point. The outer walls of the plurality of external fixing blocks 23 are rotatably connected to a circular shaft 30. A plurality of connecting iron chains 12 are provided between the plurality of external fixing blocks 23 and the sliding sleeve 9, and the two ends of the plurality of connecting iron chains 12 are respectively connected to the sliding sleeve 9 and the connecting iron chain 12. The outer groove 22 of the outer wall of the ring 8 is opened in a circumferential array for rotation connection, and the outer fixing block 23 is connected to the sliding sleeve 9 through the connecting iron chain 12. When the sliding sleeve 9 moves upward during lifting, the connecting iron chain 12 pulls the outer fixing block 23 to rotate around the outer groove 22, so that the outer fixing block 23 clamps and fixes the flange, providing support and fixing from the outside of the flange. The outer wall of the base frame 18 is opened with a plurality of sliding grooves 21 in a circumferential manner, and the outer walls of the plurality of sliding grooves 21 are slidably connected to a plurality of sliding seats 20. The plurality of sliding seats 20 are connected to the outer wall of the plurality of sliding seats 20. The outer walls are all fixedly connected with internal fixing blocks 19, and the base frame 18 serves as the basic supporting component, and the slide groove 21 opened on it provides a sliding track for the sliding seat 20. When the sliding sleeve 9 moves on the sliding column 11, the multiple sliding seats 20 are driven to slide in the slide groove 21 through the linkage of the connecting components. The internal fixing blocks 19 fixed on the outer wall of the sliding seat 20 can contact the flange from the inside of the flange, and the internal fixing blocks 19 can flexibly adjust their positions and fit tightly against the inner wall of the flange, exerting a stable supporting force on the flange from the inside. The sliding sleeve 9 and the multiple sliding seats 20 are provided with a connecting component, and the connecting component is used to realize the linkage between the sliding sleeve 9 and the sliding seat 20, and the internal stabilizing structure and the external stabilizing structure cooperate with each other to exert force from the inner and outer sides of the flange at the same time to form a full-scale stable fixing system. The device can effectively reduce the displacement and shaking of the flange during the lifting process through the coordinated stability of the inside and outside, greatly improving the safety and stability of the lifting, and ensuring the smooth progress of the lifting link in the process of continuous casting large round billets to produce wind turbine tower flanges.

[0018] The connecting assembly includes a sliding sleeve 2 16, which is slidably sleeved on the outer wall of the sliding column 11, and the outer walls on both sides of the sliding column 11 between the sliding sleeve 2 16 and the sliding sleeve 1 9 are rotatably connected to the rotating rod 13, the rotating rod 13 can rotate around the connection point, and the outer walls on both sides of the rotating rod 13 are rotatably connected to the driven rod 14 and the driven rod 2 15, respectively. One end of the driven rod 14 and the driven rod 2 15 are rotatably connected to the sliding sleeve 1 9 and the sliding sleeve 2 16 respectively. A plurality of connecting rods 17 are provided between the sliding sleeve 2 16 and the plurality of sliding seats 20, and the two ends of the plurality of connecting rods 17 are respectively hinged to the sliding sleeve 2 16 and the plurality of sliding seats 20. When the sliding sleeve 1 9 slides up and down along the sliding column 11, it drives the driven rod 14 to rotate, and the driven rod 14 drives the driven rod 14 to rotate through the rotating rod 13. The movable rod 15 rotates, so that the sliding sleeve 16 slides on the sliding column 11. A plurality of connecting rods 17 are provided between the sliding sleeve 16 and the plurality of sliding seats 20. The two ends of the plurality of connecting rods 17 are respectively connected to the sliding sleeve 16 and the plurality of sliding seats 20 in a hinged manner. The sliding of the sliding sleeve 16 drives the plurality of sliding seats 20 to slide in the slide groove 21 through the connecting rod 17, thereby realizing the linkage between the various components, enhancing the stability and coordination of the device, and realizing the linkage between the sliding sleeve 9 and the sliding seat 20. Through this linkage mode, during lifting, the plurality of external fixing blocks 23 can fix the flange stably from the outside, and at the same time drive the plurality of sliding seats 20 to drive the internal fixing block 19 to stably fix the flange from the inside, thereby enhancing the overall stability of the flange lifting.

[0019] The gantry frame 1 is located on both sides of the electric hoist 2 and is symmetrically connected to the outer walls with two slides 3. The outer walls of the connecting cover 7 on both sides are fixedly connected to the connecting seat 4, and the two slides 3 and the two connecting seats 4 are respectively provided with a stabilizing rod 5. The two ends of the stabilizing rod 5 are respectively hinged to the slide 3 and the connecting seat 4, and a hydraulic rod is installed between the slide 3 and the electric hoist 2. The two ends of the hydraulic rod are respectively fixedly connected to the slide 3 and the electric hoist 2. When the electric hoist 2 starts to lift the hook 6 and the connecting cover 7, the hydraulic rod starts synchronously, and its internal hydraulic system generates a push force, helping the electric hoist 2 to share the load, reducing the workload of the electric hoist 2, reducing its mechanical wear, and extending the service life of the equipment. At the same time, the auxiliary rising function makes the lifting process smoother, avoids shaking caused by sudden force, and improves the safety of lifting. The hydraulic rod, stabilizer bar 5 and connecting cover 7 form a triangular stabilization component. The triangle has the characteristic of stability. This component enables the connecting cover 7 to be stably supported from three directions during movement. When the connecting cover 7 is subjected to external forces such as wind force and shaking of the hoisted workpiece, the connection cover 7 is kept balanced.

[0020] The outer walls of the chassis 18 on both sides of the sliding column 11 are provided with stable grooves 29, and the outer walls of the two sides of the sliding sleeve 16 are symmetrically fixedly connected with stable blocks 31. The two stable blocks 31 correspond to the two stable grooves 29, and the outer walls of the two stable blocks 31 are provided with square grooves 32, and the chassis 18 is provided with a safety protection component adapted to the square grooves 32 on one side of the two stable grooves 29. The safety protection component includes an inner groove 25, and the two inner grooves 25 are respectively provided on one side of the stable groove 29. The outer walls of the two inner grooves 25 are slidably connected with sliding plates 27, and the outer walls of the two sliding plates 27 are fixedly connected with a control rod 26, and the control rod 26 slides through the inner groove 25 and extends to the outside. The outer wall of the sliding plate 27 away from the control rod 26 is fixedly connected with a trapezoidal block 28, and the trapezoidal block 28 and the square groove 32 are fixedly connected. The groove 32 is adapted. When the flange is fixed, when the sliding sleeve 2 16 slides to the set position, the trapezoidal block 28 is automatically inserted into the square groove 32 to form a mechanical lock, limiting the movement of the sliding sleeve 2 16, and preventing the sliding sleeve 1 9 from sliding due to the breaking of the connecting iron chain 12, which drives the sliding sleeve 2 16 to slide and cause the flange to be disengaged. The safety accident provides double protection for the operation of the device. When it is necessary to move the sliding sleeve 2 16, the operator pulls the control rod 26 to disengage the trapezoidal block 28 from the square groove 32. The operation is simple and convenient. The design of this safety protection component significantly improves the safety of the device, avoids equipment damage or casualties due to accidental sliding of components, and is particularly suitable for the lifting scenario of continuous casting large round billets to produce wind power tower flanges with extremely high safety requirements.

[0021] The outer walls of the plurality of external fixing blocks 23 are all rotatably connected with auxiliary plates 24 , which are first docked with the flange through the auxiliary plates 24 , thereby facilitating the fixing of the flange by the plurality of external fixing blocks 23 .

[0022] The outer wall of the control rod 26 is sleeved with a spring member 33, and the two sides of the spring member 33 are fixedly connected to the inner groove 25 and the sliding plate 27 respectively. When the trapezoidal block 28 is inserted into the square groove 32, the spring member 33 is in a compressed state, providing a pre-tightening force for the connection between the trapezoidal block 28 and the square groove 32, making the connection between the two tighter, effectively preventing the trapezoidal block 28 from detaching from the square groove 32 due to factors such as vibration and external force impact, further enhancing the stability and reliability of the safety protection component. When the control rod 26 is pulled to detach the trapezoidal block 28 from the square groove 32, the elastic restoring force of the spring member 33 can push the sliding plate 27 to reset, so that the safety protection component quickly returns to its initial state, which is convenient for next use, improves the convenience and efficiency of operation, and reduces the workload of the operator.

[0023] The top outer wall of the connecting cover 7 is fixedly connected with a hanging block 34, and the hanging block 34 is connected to the hook 6. The hanging block 34 and the hook 6 are connected by hooks or the like. Compared with direct connection, the connection is more convenient and quick, and the connection and separation of the hook 6 and the connecting cover 7 can be quickly realized, thereby improving the efficiency of the lifting work.

[0024] The implementation principle of a device for continuously casting large round billets to produce wind turbine tower flanges in an embodiment of the present invention is as follows: before lifting, the operator needs to perform an appearance inspection on core components such as the gantry frame 1, the electric hoist 2, the hook 6, the connecting cover 7, the fixing ring 8, and the base frame 18 to confirm that there are no cracks, deformation, and other damages; check whether the connection parts of the hydraulic rod and the stabilizer bar 5 are firm, there is no leakage in the hydraulic system pipeline, and the telescopic function of the hydraulic rod is normal; test the elastic performance of the spring part 33 in the safety protection assembly to ensure that the trapezoidal block 28 can be normally detached from and inserted into the square groove 32; check the electronic control system of the electric hoist 2 to ensure its sensitive operation and stable operation.

[0025] Thus, by starting the electric hoist 2 and controlling it to slide horizontally on the gantry frame 1, the hook 6 is moved to the top of the hanging block 34 on the connecting cover 7, and the connection between the hook 6 and the hanging block 34 is completed. Subsequently, the electric hoist 2 and the hydraulic rod are started synchronously. The electric hoist 2 provides the main lifting force, and the hydraulic rod starts the internal hydraulic system to generate auxiliary thrust. The two work together to lift the connecting cover 7, the fixing ring 8 and the base frame 18 and other components steadily. In this process, the hydraulic rod shares part of the load of the electric hoist 2, reduces its mechanical wear, and ensures the stability of the lifting. As the connecting cover 7 rises, the sliding sleeve 9 moves up synchronously along the sliding column 11, and the lifting force is increased by 10%. The linkage of the rotating rod 13, the driven rod 14, the driven rod 2 15 and the connecting rod 17 drives the sliding sleeve 2 16 to slide on the sliding column 11, and then drives multiple sliding seats 20 to slide in the sliding groove 21 of the base frame 18. The inner fixing block 19 on the outer wall of the sliding seat 20 gradually fits the inner wall of the flange, exerting a stable supporting force on the flange from the inside, limiting the radial movement and shaking of the flange. The movement of the sliding sleeve 1 9 drives the outer fixing block 23 to rotate around the outer groove 22 through the connecting iron chain 12, and the auxiliary plate 24 on the outer fixing block 23 rotates to fit the outer surface of the flange, providing support and fixation for the flange from the outside to prevent the flange from tilting or flipping. In the process, the triangular stabilizing assembly composed of the hydraulic rod, the stabilizing rod 5 and the connecting cover 7 plays a key role. When the connecting cover 7 is disturbed by external forces such as wind and workpiece shaking, the hydraulic rod and the stabilizing rod 5 automatically adjust the angle and the size of the supporting force according to the force conditions, disperse the external force, maintain the balance and stability of the connecting cover 7, and ensure that the lifting operation is safe and efficient. During the lifting process, when the sliding sleeve 16 slides to the set position, the stabilizing block 31 on the sliding sleeve 16 is connected to the stabilizing groove 29, and the trapezoidal block 28 is automatically inserted into the square groove 32 of the stabilizing block 31, and the sliding sleeve 16 is mechanically locked. This locking action can prevent the hydraulic Unexpected factors such as system failure and abnormal connection components may cause the sliding sleeve 2 16 to slide, thereby avoiding instability of the entire lifting system caused by the loss of control of the sliding sleeve 2 16, and even serious safety accidents such as workpiece falling. When the flange drops to the specified position, the operator pulls the control rod 26 to overcome the elastic force of the spring member 33, so that the sliding plate 27 moves, and the trapezoidal block 28 disengages from the square groove 32, releasing the lock on the sliding sleeve 2 16 and preparing for the next lifting. Subsequently, the hook 6 is separated from the lifting block 34, and the electric hoist 2 and the hydraulic rod are turned off to complete the lifting operation. This operation ensures that the safety protection components can be recycled and continuously guarantees the safety of lifting.
