Description

Technical Field

[0001] The present invention relates to the technical field of tower cutting, and in particular to a wind power tower cutting device and a cutting method. Background Art

[0002] As a crucial supporting structure for wind turbines, wind turbine towers have grown in response to rising global energy demand and the crisis facing traditional fossil fuels. Furthermore, to address environmental pollution and climate change associated with traditional energy use, wind power generation has garnered widespread attention as a clean energy source. Early wind turbine towers featured simple designs, often employing steel truss structures. Limited by the materials and manufacturing processes available at the time, these structures resulted in poor overall performance and reliability, and low production efficiency. Advances in wind power technology and the increased capacity of individual units have placed higher demands on wind turbine tower performance. This, coupled with policy support from various countries and growing market demand, has driven the development of wind turbine tower technology. However, current wind turbine tower technology still faces numerous challenges, including adapting to complex environments like mountainous and offshore environments, as well as addressing transportation and installation challenges. This is particularly true of offshore wind turbine towers, which face high costs and significant construction risks.

[0003] Currently, when cutting a specific part of a wind turbine tower, a cutting machine is a commonly used tool. However, when the cutting machine cuts the surface of the wind turbine tower, the gap created by the cutting machine is likely to clamp the cutting blade.

At the same time, the operator needs to expend greater effort to control the movement and cutting speed of the cutting machine, affecting cutting efficiency. Therefore, this does not meet existing needs. In response to this, we have proposed a wind turbine tower cutting device and cutting method. Summary of the Invention

[0014] This solution also proposes a wind turbine tower cutting method, comprising the following steps: S1. An operator holds a cutting device and cuts a wind turbine tower. During the cutting process, the drive motor operates, and the shaft of the drive motor drives the blade to rotate via the connecting sleeve. S2. During the rotation of the drive motor shaft, the centrifugal block, under the influence of centrifugal force, presses the first interference rod, causing the first interference rod to interfere with the connecting sleeve.

[0015] The present invention has the following beneficial effects: 1. This wind turbine tower shell cutting and cutting method: During the cutting operation, the drive motor starts to rotate the shaft, generating a centrifugal force field. Under the action of this centrifugal force field, the conical block on the shaft swings upward along the shaft. The conical upper end of the block fits into the docking groove to form a dynamic support structure, and the bottom end retains a radial gap with the sliding groove to allow the connecting sleeve to move. The centrifugal block moves away from the drive motor on the shaft, and its convex arc surface gradually contacts the conical end face of the first contact rod, pushing the first contact rod to move, and then pushing the connecting sleeve, driving the blade to move. The reset spring cooperates to make the blade move back and forth laterally. Under this working principle, the blade can cover a wider area in a single cutting action, effectively reducing the number of cuts required, and also minimizes the risk of the cutting object getting stuck in the blade, making cutting smoother and further improving overall cutting efficiency.

[0016] 2. The wind turbine tower shell cutting and cutting method: When the cutting equipment is in operation, the centrifugal force generated by the driving motor causes the centrifugal block to move away from the rotating shaft, and during its movement, it abuts against the second abutment rod, causing the blade connected to the connecting sleeve through the spherical seat to tilt; and the tilted blade covers a wider area, reducing the number of cutting and movement times, and improving efficiency; the cutting force is dispersed; local wear of the blade is reduced, the equipment life is extended, the knife is avoided as much as possible, the cutting smoothness is improved, and the overall cutting efficiency is further improved.

[0017] 3. The wind turbine tower shell cutting and cutting method realizes the extension and contraction of several second resistance rods in different states through the cooperation of the driving motor, the centrifugal block and the cylinder, and utilizes the centrifugal motion of the eccentrically arranged cylinder and the centrifugal block, as well as the sliding cooperation between the rib and the annular groove, so as to make the blade tilt smoothly; the tilted blade can change the cutting angle, increase the flexibility and diversity of cutting, avoid the knife from getting stuck as much as possible, improve the cutting smoothness, and further improve the overall cutting efficiency.

DETAILED DESCRIPTION

[0026] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0027] Example 1: This example aims to solve the problem that the cutting machine is often used for cutting wind turbine towers, but the gaps created during cutting can easily clamp the blade. When the blade is clamped, the motor needs to output a greater torque or cause overload, and the operator has difficulty controlling it, which affects the cutting efficiency. Figure 1-Figure 7 A wind turbine tower cutting device and cutting method include a cutting shell 10 and a blade 11 for cutting, and a drive motor 12 for driving the blade 11. An adjusting mechanism 20 for adjusting the movement of the blade 11 is provided inside the cutting shell 10. The adjusting mechanism 20 includes a connecting sleeve 21 sliding on the rotating shaft of the drive motor 12, and a centrifugal block 22 provided on the rotating shaft of the drive motor 12. A first interference rod 23 is provided at the end of the centrifugal block 22 away from the blade 11. The centrifugal block 22 is used to drive the movement of the first interference rod 23. Sliding grooves 24 are symmetrically provided on the rotating shaft of the drive motor 12. A docking groove 30 adapted to the sliding groove 24 is provided on the inner wall of the connecting sleeve 21. A conical block 25 is slidably fitted between the sliding groove 24 and the docking groove 30. A first spring 31 is installed between the conical block 25 and the docking groove 30.

[0028] The adjustment mechanism 20 also includes a support shell 32 installed on the rotating shaft of the drive motor 12. There are several support shells 32, and the several support shells 32 are installed in a circular row on the rotating shaft of the drive motor 12. A support column 33 is installed on the inside of the support shell 32. A movable groove 34 adapted to the support column 33 is opened on the centrifugal block 22. The support column 33 slides inside the movable groove 34. A second spring 35 is installed between the centrifugal block 22 and the support shell 32.

[0029] A first slide groove 40 is provided on the surface of the support shell 32, and a first slider 41 is installed on the first resistance rod 23. The first slider 41 slides and fits inside the first slide groove 40. A No. 1 spring 42 is sleeved on the surface of the first resistance rod 23. One end of the No. 1 spring 42 is connected to the first slider 41, and the other end of the No. 1 spring 42 is connected to the inner wall of the first slide groove 40.

[0030] A groove 43 is provided on the rotating shaft of the driving motor 12, and a protrusion 44 is installed on the inner wall of the connecting sleeve 21. The protrusion 44 slides in the groove 43, and a return spring 45 is installed between the groove 43 and the protrusion 44. Through the cooperation of the return spring 45, the connecting sleeve 21 is reset by the pulling force of the return spring 45 after moving. At the same time, several centrifugal blocks 22 are provided, so when the driving motor 12 is running, the connecting sleeve 21 can drive the blade 11 to move back and forth. When the driving motor 12 is running, the first contact rod 23 contacts the connecting sleeve 21, so the protrusion 44 slides from one end of the groove 43 to the other end, and the connecting sleeve 21 is displaced.

[0031] See Figure 2 and Figure 3 In specific implementation, during the cutting process, the driving motor 12 runs and generates centrifugal force. Therefore, the conical block 25 located on the rotating shaft of the driving motor 12 is swung upward, and its upper end enters the docking groove 30. At this time, there is a gap between the bottom end of the conical block 25 and the sliding groove 24, so that the connecting sleeve 21 has a certain range of movement; at the same time, the centrifugal block 22 is away from the rotating shaft of the driving motor 12 under the action of centrifugal force, so that during the movement of the centrifugal block 22, the shape of its surface is used to interfere with the first interference rod 23. Therefore, during the movement of the first interference rod 23, the connecting sleeve 21 is pushed. At this time, the connecting sleeve 21 slides on the rotating shaft of the driving motor 12, and the blade 11 is driven to move while the connecting sleeve 21 slides. See Figure 2 and Figure 3Therefore, during the cutting process, the blade 11 generates a lateral reciprocating motion. This lateral reciprocating motion of the blade 11 can expand the effective area of a single cut. For example, when cutting a wide plate, if the blade 11 only cuts vertically downward, it can only cut a very narrow strip at a time. However, by slightly reciprocating lateral motion, a wider width can be covered in a single cut, and the number of cuts can be reduced. At the same time, the possibility of the blade 11 being pinched by the cutting object can be minimized, thereby significantly improving the overall cutting efficiency.

[0032] In this embodiment, during the cutting operation, after the drive motor 12 is started, the shaft rotates to generate a centrifugal force field. At this time, the conical block 25 located on the shaft is swung upward in the axial direction due to the centrifugal force, and its conical upper end is embedded in the pre-designed docking groove 30, forming a dynamic support structure. At the same time, a certain radial gap is maintained between the bottom end of the conical block 25 and the sliding groove 24, so that the connecting sleeve 21 has a certain range of movement. At the same time, the centrifugal block 22 moves away from the driving motor 12 on the rotating shaft under the action of centrifugal force, and its convex arc surface forms asymptotic contact with the conical end face of the first interference rod 23. As the driving motor 12 continues to run, the centrifugal block 22 pushes the first interference rod 23 to produce displacement, so the first interference rod 23 pushes the connecting sleeve 21, causing the connecting sleeve 21 to slide while driving the blade 11 to move. At the same time, with the cooperation of the reset spring 45, the blade 11 can move back and forth laterally during the cutting process; through the slight lateral reciprocating movement of the blade 11, the blade 11 can cover a wider area in a single cutting action, effectively reducing the number of cutting times required. At the same time, this movement method can also minimize the risk of the cutting object getting stuck in the blade 11, thereby greatly improving the overall cutting efficiency.

[0033] Example 2: This example is intended to further solve the problem of preventing the cutting blade 11 from being clamped by the gap generated by cutting. This example is an improvement made on the basis of Example 1. For details, please refer to Figure 1-Figure 7 A connecting rod 50 is installed on the inner ring of the blade 11, and a ball head seat 51 is installed on the end of the connecting rod 50. The ball head seat 51 is set so that the blade 11 can be tilted smoothly. A circular groove 52 is provided on the surface of the connecting sleeve 21 to match the ball head seat 51, and the ball head seat 51 is movably fitted inside the circular groove 52.

[0034] See Figure 2 and Figure 3A transverse groove 53 is symmetrically provided in the inner wall of the connecting sleeve 21, and a plurality of transverse grooves 53 are provided. A plurality of transverse grooves 53 are arranged in a ring on the connecting sleeve 21. A transverse rod 54 is slidably fitted inside the transverse groove 53. The upper end of the transverse rod 54 contacts the inner ring of the blade 11. A push spring 55 is installed between the transverse rod 54 and the transverse groove 53. A trapezoidal rod 60 is installed on the conical block 25. A notch 61 is provided on the surface of the transverse rod 54 to match the end of the trapezoidal rod 60. The transverse groove 53 is communicated with the inside of the docking groove 30.

[0035] See Figure 2 and Figure 3 In specific implementation, during the cutting process, the drive motor 12 runs and generates centrifugal force. At the same time, the centrifugal block 22 moves away from the rotating shaft of the drive motor 12 under the action of centrifugal force, so that during the movement of the centrifugal block 22, the shape of its surface is used to interfere with the second interference rod 62. Therefore, during the movement of the second interference rod 62, the blade 11 is interfered with. Since the blade 11 is connected to the connecting sleeve 21 through the spherical seat, the blade 11 is tilted when it is interfered with; during the cutting operation, the blade 11 can cover a wider area by cutting in the inclined direction, which can significantly improve the cutting efficiency, reduce the number of cutting times and the moving path, and at the same time avoid the risk of the cutting object getting stuck in the blade 11 as much as possible, making the cutting smooth and further improving the overall cutting efficiency.

[0036] In this embodiment: During the cutting process, the driving motor 12 operates to generate centrifugal force, and the centrifugal block 22 moves away from the rotating shaft of the driving motor 12 under the action of the centrifugal force. When the centrifugal block 22 moves, its surface shape will interfere with the second interference rod 62, causing the second interference rod 62 to move and interfere with the blade 11. Because the blade 11 is connected to the connecting sleeve 21 through a spherical seat, the blade 11 will tilt when it is interfered with. At the same time, the inclined cutting blade 11 can cover a wider area, which can significantly improve the cutting efficiency, reduce the number of cuts and the moving path; it can also avoid the risk of the cutting object getting stuck in the blade 11 as much as possible, ensure a smooth cutting process, and further improve the overall cutting efficiency.

[0037] Embodiment 3: This embodiment is intended to promote the solution of the problem that since the centrifugal blocks 22 are provided in several groups, when the several groups of centrifugal blocks 22 move simultaneously, several second conflicting blocks will conflict with the blade 11 at the same time, which may cause the blade 11 to not tilt smoothly. This embodiment is an improvement made on the basis of embodiment 2. For details, please refer to Figure 1-Figure 7 A second interference rod 62 is movably inserted into the support shell 32 . The length of the second interference rod 62 is greater than the length of the first interference rod 23 , and the second interference rod 62 has the same specifications as the first interference rod 23 .

[0038] See Figure 2 、 Figure 3 and Figure 6In a specific implementation, a cylinder 70 is installed on the cutting shell 10. The cylinder 70 is eccentrically arranged on the outside of the rotating shaft of the driving motor 12. A convex rib 71 is installed on the upper side of the centrifugal block 22. An annular groove 72 is opened on the inner wall of the cylinder 70. The convex rib 71 slides with the annular groove 72 to make the movement of the centrifugal block 22 more powerful, and to avoid as much as possible the centrifugal force that causes the centrifugal block 22 to be unable to be thrown out smoothly. At the same time, several centrifugal blocks 22 are in sliding contact with the cylinder 70.

[0039] When the drive motor 12 is started, the centrifugal blocks 22 rotate accordingly, and the ribs 71 cooperate with the annular grooves 72 on the inner wall of the cylinder 70, so that several centrifugal blocks 22 contact the inner wall of the cylinder 70. When one of the centrifugal blocks 22 moves to the lower end of the cylinder 70, the inner wall of the bottom side of the cylinder 70 is close to the rotating shaft of the drive motor 12, so that the centrifugal block 22 is restricted and will not be thrown out, causing the second interference rod 62 corresponding thereto not to extend; when one of the centrifugal blocks 22 rotates to the upper side of the rotating shaft, since the rotating shaft of the drive motor 12 is at a certain distance from the inner wall of the cylinder 70, the centrifugal block 22 has a certain space for movement, and at the same time, the centrifugal block 22 uses centrifugal force to cooperate with the annular grooves 72 and the ribs 71, wherein the centrifugal block 22 is away from the rotating shaft of the drive motor 12, so the second interference rod 62 corresponding thereto extends and interferes with the blade 11, so that the blade 11 tilts smoothly.

[0040] This solution also proposes a wind turbine tower cutting method, comprising the following steps: S1. The operator holds the cutting device and cuts the wind turbine tower. During the cutting process, the drive motor 12 is operated, and the shaft of the drive motor 12 drives the blade 11 to rotate via the connecting sleeve 21. S2. During the rotation of the shaft of the driving motor 12, the centrifugal block 22 exerts centrifugal force on the first abutting rod 23, causing the first abutting rod 23 to abut against the connecting sleeve 21. At this time, the connecting sleeve 21 is displaced, so that the blade 11 is in a moving state, thereby expanding the cutting range. S3. When the centrifugal block 22 is affected by the centrifugal force, the centrifugal block 22 will simultaneously resist the second resisting rod 62. Therefore, the second resisting rod 62 resists the blade 11, causing the blade 11 to tilt, thereby increasing the cutting angle and facilitating cutting.

[0041] In this embodiment, when the drive motor 12 is activated, the centrifugal masses 22 rotate accordingly. The ribs 71 engage the annular grooves 72 on the inner wall of the cylinder 70, maintaining contact with the inner wall of the cylinder 70. When a centrifugal mass 22 reaches the lower end of the cylinder 70, the lower inner wall of the cylinder 70 is close to the rotating shaft of the drive motor 12, restricting the centrifugal mass 22 from being ejected, and the corresponding second abutment rod 62 does not extend. However, when a centrifugal mass 22 reaches the upper side of the rotating shaft, the upper inner wall of the cylinder 70 is farther from the rotating shaft of the drive motor 12, allowing the centrifugal mass 22 to move away from the rotating shaft. Centrifugal force, the annular grooves 72, and the ribs 71 allow the centrifugal mass 22 to move away from the rotating shaft, causing the corresponding second abutment rod 62 to extend and abut the blade 11, allowing the blade 11 to tilt smoothly.

[0042] It should be noted that, in this document, relational terms such as first and second, etc., are used only to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the terms "comprises," "comprising," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that includes a list of elements includes not only those elements but also other elements not explicitly listed, or elements inherent to such process, method, article, or apparatus.

[0043] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.

The wind turbine tower cutting device according to claim 8, characterized in that: A cylinder (70) is mounted on the cutting housing (10), the cylinder (70) being eccentrically arranged on the outside of the rotating shaft of the driving motor (12), a convex rib (71) being mounted on the upper side of the centrifugal block (22), an annular groove (72) being formed on the inner wall of the cylinder (70), the convex rib (71) being in sliding engagement with the annular groove (72), and a plurality of the centrifugal blocks (22) being in sliding contact with the cylinder (70).

10. A wind turbine tower cutting method, according to the wind turbine tower cutting device according to claim 9, characterized in that: The steps include: S1. The operator holds the cutting device and cuts the wind turbine tower. During the cutting process, the drive motor (12) operates, and the shaft of the drive motor (12) drives the blade (11) to rotate using the connecting sleeve (21); S2. During the rotation of the shaft of the driving motor (12), the centrifugal block (22) exerts influence on the first abutting rod (23) under the influence of centrifugal force, causing the first abutting rod (23) to abut against the connecting sleeve (21). At this time, the connecting sleeve (21) is displaced, so that the blade (11) is in a moving state, thereby expanding the cutting range. S3. When the centrifugal block (22) is affected by the centrifugal force, the centrifugal block (22) will simultaneously resist the second resisting rod (62), so that the second resisting rod (62) resists the blade (11), causing the blade (11) to tilt, thereby increasing the cutting angle and facilitating cutting.
