Description

Technical Field

[0001] This application relates to the field of wind power component processing, and in particular to a wind power tower welding auxiliary processing device. Background Technology

[0002] Wind turbine towers, as devices that provide clean energy, are now widely used. Wind turbine towers are relatively tall, typically 70-80 meters, so the tower section is usually welded from multiple sections. During welding, the completed sections are first transported to a positioning device using a specialized hoisting device. The positioning device includes a base with two mounting seats that can slide along the width and vertical directions of the base, and rotating rollers are installed on the mounting seats. Two sections are then placed end-to-end on the rotating rollers, and the mounting seats are adjusted to align the two sections. The welding machine is then moved over, and the welding head is inserted into the joint between the two sections. The inner bevel between the two sections is welded by the welding machine simultaneously rotating the sections driven by the rotating rollers.

[0003] A push roller is also rotatably connected to the base. The rotation axis of the push roller is set along the tangential direction of the cylinder section. The rotation of the push roller can drive the cylinder section to move along its own axis. After the welding between two cylinder sections is completed, the push roller is used to move them apart. Then the welding machine is removed, and another cylinder section is hoisted in by the hoisting device. After the three cylinder sections are aligned and positioned, the welding machine is inserted again for welding. By repeating the above steps, the welding of tall wind turbine towers can be completed quickly.

[0004] Regarding the aforementioned technologies, each insertion of the welding machine requires alignment of the welding bevel. Currently, most welding machines use laser scanning alignment, which offers high precision but takes more time, thus affecting welding efficiency. Summary of the Invention

[0005] In order to enable the rapid installation of wind turbine tower sections, this application provides an auxiliary processing device for welding wind turbine tower sections.

[0006] This application provides a wind turbine tower welding auxiliary processing device, which adopts the following technical solution:

[0007] A wind turbine tower welding auxiliary processing device includes a support rod and a hydraulic cylinder. The support rod is slidably connected to a slide rod in a vertical direction, and the hydraulic cylinder drives the slide rod to slide. Two horizontally parallel support rods are spaced apart on the slide rod. Support wheels for erecting tower sections are rotatably connected to the support rods, and the rotation axis of the support wheels is set along the length of the support rod. The slide rod slides to place the tower section on a positioning device. A first limiting block is provided at one end of the support rod near the slide rod. A welding machine is slidably connected to the slide rod in a vertical direction. The slide rod also has a drive assembly for driving the welding machine to slide. The drive assembly includes a mounting base, a lead screw, and a motor. The lead screw is rotatably connected to the support rod, and the rotation axis of the lead screw is set in a vertical direction. The motor drives the lead screw to rotate. The mounting base is connected to the lead screw via a lead screw nut. The welding machine is connected to the mounting base.

[0008] By adopting the above technical solution, before welding begins, a cylindrical section is hoisted onto the positioning device using a hoisting device. During the welding of the cylindrical section, the hydraulic cylinder is activated to move the slide bar and the support rod upward as a whole. The hoisting device then directly places another cylindrical section onto the two support rods in the horizontal direction. The cavity between the two support rods is just enough to allow the hoisting device to be positioned, so that the cylindrical section can be smoothly placed onto the support rods and ensures that the cylindrical section is pressed against the first limiting block along the length of the support rods. At this time, the welding machine should be aligned vertically with the welding bevel of the cylindrical section.

[0009] Subsequently, the hydraulic cylinder drives the slide bar down and places the cylindrical section on the positioning device. Then, the positioning device's own push roller pushes the existing cylindrical section on the positioning device over, so that the two cylindrical sections come into contact. Then, the motor drives the lead screw to rotate, thereby driving the welding machine to slide up and down and move to the welding bevel. The positioning device drives the two cylindrical sections to rotate, and at the same time, the welding machine starts to work and weld. After welding is completed, the positioning device's own push roller removes the cylindrical section from the frame in a horizontal direction. Then, the hydraulic cylinder raises the slide bar and the frame again, and the hoisting device puts the cylindrical section back onto the frame. Repeating the above steps completes the welding of the tower.

[0010] Optionally, the welding machine is slidably connected to the mounting base along the length of the support rod, and the mounting base is further provided with a welding machine cylinder for driving the welding machine to slide.

[0011] By adopting the above technical solution, the position of the welding machine is changed by driving the welding machine to slide through the cylinder, so that when dealing with cylinder sections of different lengths, the welding machine can always be aligned with the welding bevel in the horizontal direction; and after the cylinder drives the welding machine to adjust once, subsequent cylinder sections of the same length do not need to be adjusted again.

[0012] Optionally, the support rod is provided with a second limiting block. A sliding groove is formed on the support rod along its length direction. A sliding seat is slidably connected in the sliding groove. A rotating shaft is rotatably connected to the sliding seat. The rotation axis of the rotating shaft is set along the width direction of the support rod. The second limiting block is rotatably connected to the rotating shaft. The rotation axis of the second limiting block is set along the length direction of the rotating shaft. A torsion spring is provided on the rotating shaft to limit the rotation of the second limiting block. The second limiting block rotates to be submerged in the sliding groove. A rack is provided in the sliding groove. A gear is fixedly connected to the rotating shaft. The gear is coaxial with the rotating shaft. The rack meshes with the gear. A clamping cylinder is also provided in the sliding groove to drive the sliding seat to slide. When the gear is located at one end of the rack near the support rod, the first limiting block is in a vertical state. A magnet is provided on the sliding seat. When the second limiting block is in a vertical state, the magnet attracts the second limiting block.

[0013] By adopting the above technical solution, considering the difficulty of simultaneously placing the cylinder section against the first limiting block and onto the support wheel in one go, the hoisting device can simply sleeve the cylinder section onto the frame rod. Then, a cylinder drives the sliding seat to slide towards the first limiting block. During the sliding process, the gear meshes with the rack and rotates, causing the second limiting block to gradually rotate and eventually reach a vertical position. Once the second limiting block is vertical, it cannot continue to rotate due to interference between the sliding seat and the magnet, at which point it abuts... The cylinder restarts, causing the second limiting block to push the cylinder section along the frame until it contacts the first limiting block, thus positioning the cylinder section along the length of the frame. Before the cylinder section on the positioning device approaches, the pushing cylinder needs to retract. During the retraction of the pushing cylinder, the second limiting block will retract until the gear and rack mesh. The gear then starts to rotate and the torsion spring starts to compress. When the torsion spring is compressed to a certain extent, the second limiting block disengages from the magnet and begins to rotate until it is submerged in the groove, thus avoiding interference when the two cylinder sections are joined.

[0014] Optionally, the support rod is slidably connected to an offset rod in the vertical direction, and multiple pulleys are rotatably connected to the offset rod. The multiple pulleys are spaced apart along the length of the support rod, and the rotation axis of the pulleys is set along the width of the support rod. The support rod is also provided with a spring, one end of which is fixedly connected to the support rod, and the other end of which is fixedly connected to the offset rod. When the spring is in its natural state, the pulley is higher than the support wheel. The support rod is also provided with a limiting member for restricting the offset rod from sliding in the vertical direction.

[0015] By adopting the above technical solution, considering that the friction force when the cylinder section slides on the support rod may be a bit large, the pulley can reduce the friction force when the cylinder section moves along the length of the support rod. When the cylinder section does not abut against the first limiting block, the offset rod cannot sink, and the height of the pulley is higher than the support wheel. When the cylinder section abuts against the first limiting block, the limiting component releases the restriction on the offset rod, and the offset rod sinks under the action of the cylinder section's gravity until the cylinder section falls on the support wheel and stops sliding. When the cylinder section detaches from the support rod, the offset rod moves upward under the action of spring one. At this time, the height of the pulley is higher than the support wheel again, and the limiting component limits the offset rod again to prepare for receiving the arrival of the next cylinder section.

[0016] Optionally, the limiting member includes a stop bar, the first limiting block is slidably connected to the frame rod along the length direction of the frame rod, and the frame rod is also provided with a spring two for driving the first limiting block away from the support rod; the stop bar is fixedly connected to the first limiting block, and when the spring two is in the natural state, the stop bar abuts against the underside of the bias rod to limit the sliding of the bias rod.

[0017] By adopting the above technical solution, when the cylinder section is not against the first limiting block, the first stop rod is located below the offset rod. At this time, the offset rod cannot move down, and the pulley cannot move down either. When the cylinder section is gradually pushed by the second limiting block and the second spring is compressed, the stop rod initially moves with the first limiting block until the first stop rod disengages from below the offset rod. Then, the offset rod falls due to the weight of the cylinder section, and the pulley falls down. The cylinder section is placed on the support wheel, thus stopping the sliding.

[0018] Optionally, the limiting component further includes a second stop rod, which is fixedly connected to the second limiting block. The second stop rod passes through the offset rod in a vertical direction. A locking block is provided at one end of the second stop rod near the offset rod. An abutment groove for the locking block to slide is provided on the offset rod. An unlocking hole for the locking block to pass through is provided at one end of the abutment groove near the support rod.

[0019] By adopting the above technical solution, the second stop is similar to the first stop. The first stop slides with the second limiting block. At this time, the locking block is below the offset rod, and the offset rod cannot sink. When the second limiting block slides above the unlocking hole, the offset rod slides down under the pressure of the cylinder section, and the locking block passes through the unlocking hole. Limiting is performed at both ends of the offset rod to improve the stability of the limiting component.

[0020] Optionally, the first stop bar is a telescopic bar, which can extend and retract along the length direction of the offset bar; the first stop bar is also provided with bolts for limiting its own extension and retraction.

[0021] By adopting the above technical solutions, it is possible to adapt to cylinder sections of different lengths.

[0022] Optionally, the support pole is also equipped with a counterweight.

[0023] By adopting the above technical solution, the bending moment of the sliding rod and the frame rod on the support rod is reduced, making the support rod more stable.

[0024] In summary, this application includes the following beneficial technical effects:

[0025] 1. By setting up support rods, frame rods and sliding rods, this application allows the tower section to slide directly horizontally onto the outside of the welding machine during welding. This eliminates the need to reposition the welding machine along the length of the tower section using laser after each lifting operation, thus reducing operational precision and saving time.

[0026] 2. This application, through the arrangement of the second limiting block, sliding seat, rotating shaft, gear and rack, enables the cylindrical section to be accurately positioned along the length of the frame after being fitted onto the frame. Attached Figure Description

Detailed Implementation

[0034] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0035] This application discloses an auxiliary processing device for welding wind turbine towers. (Refer to...) Figure 1 and Figure 3 The device includes a support rod 1 and a hydraulic cylinder 11. The support rod 1 is arranged vertically and fitted with a sliding rod 2. The hydraulic cylinder 11 is used to drive the sliding rod 2 to slide vertically. Two horizontally parallel support rods 3 are arranged on the sliding rod 2. A support wheel 31 for supporting the cylindrical section 7 is rotatably connected to the support rod 3. The rotation axis of the support wheel 31 is arranged along the length direction of the support rod 3. A positioning device 5 is placed below the support rod 3. The sliding rod 2 slides downward to place the cylindrical section 7 on the positioning device 5. A first limiting block 33 is provided at one end of the support rod 3 near the sliding rod 2 for the cylindrical section 7 to abut along the length direction of the support rod 3.

[0036] To ensure safety when the cylindrical section 7 is fitted into the support rod 3, the welding machine 62 is slidably connected to the slide rod 2 in the vertical direction. The slide rod 2 is also equipped with a drive assembly for driving the welding machine 62 to slide. In this embodiment, the drive assembly includes a mounting base 61, a lead screw 64, and a motor 65. The lead screw 64 is rotatably connected to the support rod 1, and the rotation axis of the lead screw 64 is set in the vertical direction. The motor 65 is used to drive the lead screw 64 to rotate. The mounting base 61 is connected to the lead screw 64 through a lead screw nut. The welding machine 62 is connected to the mounting base 61. At the same time, to accommodate cylindrical sections 7 of different lengths, the welding machine 62 is slidably connected to the mounting base 61 along the length direction of the support rod 3. Meanwhile, a welding machine cylinder 63 is fixed on the mounting base 61. One end of the welding machine cylinder 63 is fixedly connected to the mounting base 61, and the other end of the welding machine cylinder 63 is connected to the welding machine 62.

[0037] In order to reduce the bending moment exerted by the cylinder section 7 and the frame rod 3 on the support rod 1, there is also a counterweight 8 on the frame rod 3. The counterweight 8 can make the center of gravity of the frame rod 3 closer to the support rod 1.

[0038] Before welding the tower section, one section 7 needs to be placed on the positioning device 5 below the support rod 3 using a hoisting device, and this section 7 needs to maintain a certain distance from the support rod 3. Then, the hydraulic cylinder 11 is activated to move the slide rod 2 and the support rod 3 upward as a whole, and the drive motor 65 drives the lead screw 64 to rotate, so that the welding machine 62 is close to the support rod 3, avoiding the section 7 hitting the welding machine 62 when it is being fitted. Then, the other section 7 is directly fitted onto the support wheel 31 of the two support rods 3 in the horizontal direction using a hoisting device. The cavity between the two support rods 3 is just enough to allow the hoisting device to be positioned, so that the section 7 can be smoothly fitted onto the support rod 3, and ensure that the section 7 is pressed against the first limiting block 33 along the length of the support rod 3. At this time, the welding machine 62 should be aligned with the welding bevel of the section 7 in the horizontal direction, but there is a certain height difference between it and the welding bevel.

[0039] Then, the hydraulic cylinder 11 drives the slide bar 2 to slide down and place the cylinder section 7 on the positioning device 5. The positioning device 5 then uses its own push rollers to push the existing cylinder section 7 onto the positioning device 5, bringing the two cylinder sections 7 into contact. Subsequently, the motor 65 drives the lead screw 64 to rotate, thereby driving the welding machine 62 to slide up and down and move to the welding bevel. The positioning device 5 drives the two cylinder sections 7 to rotate, and simultaneously, the welding machine 62 begins welding. After welding is completed, the push rollers on the positioning device 5 move the two cylinder sections 7 away from the support rod 1. Figure 2 To the right, remove the cylindrical section 7 from the support rod 3 horizontally; then, lift the slide rod 2 and support rod 3 again using the hydraulic cylinder 11, and once again use the hoisting device to put the cylindrical section 7 back onto the support rod 3; repeat the above steps to complete the welding of the tower.

[0040] refer to Figure 3 and Figure 4 Considering the difficulty of placing the cylinder section 7 onto the support wheel 31 simultaneously with the first limiting block 33 using the hoisting device, the frame rod 3 is also equipped with a second limiting block 34. A groove 35 is formed along the length of the frame rod 3, and a sliding seat 341 is slidably connected in the groove 35. A rotating shaft 40 is rotatably connected to the sliding seat 341, and the axis of rotation of the rotating shaft 40 is set along the width of the frame rod 3. The second limiting block 34 is rotatably connected to the rotating shaft 40, and the axis of rotation of the second limiting block 34 is set along the length of the rotating shaft 40. The rotating shaft 40 is equipped with a... A torsion spring 39 restricts the rotation of the second limiting block 34; the second limiting block 34 rotates to be submerged in the slide groove 35; a rack 38 is provided in the slide groove 35, and a gear 37 is fixedly connected to the rotating shaft 40. The gear 37 is coaxial with the rotating shaft 40, and the rack 38 meshes with the gear 37. A clamping cylinder 45 is also provided in the slide groove 35 to drive the sliding seat 341 to slide; when the gear 37 is located at one end of the rack 38 near the support rod 1, the first limiting block 33 is in a vertical state; a magnet 46 is provided on the sliding seat 341, and when the second limiting block 34 is in a vertical state, the magnet 46 attracts the second limiting block 34.

[0041] refer to Figure 4 and Figure 5To enable the hoisting device, the cylindrical section 7 can simply be fitted onto the support rod 3. The sliding seat 341 is driven to slide towards the first limiting block 33 by the abutting cylinder 45. During the sliding of the sliding seat 341, the gear 37 meshes with the rack 38 and rotates. At this time, the second limiting block 34 gradually rotates and eventually reaches a vertical position. After the second limiting block 34 reaches a vertical position, it cannot continue to rotate due to the interference between the sliding seat 341 and the magnet 46. At this point, the abutting cylinder drives the second limiting block 34 to push the cylindrical section 7 along the support rod 3 until it abuts against the first limiting block 33. This completes the positioning of the cylindrical section 7 along the length of the support rod 3. Before the cylindrical section 7 on the positioning device 5 approaches, it needs to retract and tighten the cylinder 45. During the retraction of the cylinder 45, the second limiting block 34 will retract first until the gear 37 meshes with the rack 38. Then the gear 37 starts to rotate and the torsion spring 39 starts to compress. When the torsion spring 39 is compressed to a certain extent, the second limiting block 34 disengages from the magnet 46 and starts to rotate until the second limiting block 34 is submerged in the slide groove 35. This avoids the cylindrical section 7 being sandwiched between the two when they are joined. With this hoisting device, it is only necessary to put the cylindrical section 7 on the frame rod 3 without positioning the frame rod 3 in the length direction, which reduces the operation accuracy and saves operation time.

[0042] Considering that the cylindrical section 7 has a certain mass, if it were to slide directly against the support wheel 31, it might encounter significant frictional resistance, potentially preventing it from moving and causing wear on the support wheel 31. Therefore, a bias rod 32 is slidably connected to the frame rod 3 in the vertical direction. Multiple pulleys 321 are rotatably connected to the bias rod 32, with the rotation axis of the pulleys 321 set along the width direction of the frame rod 3 and the multiple pulleys 321 spaced apart along the length direction of the frame rod 3. The frame rod 3 is also equipped with a spring 332 for driving the bias rod 32 closer to the frame rod 3. When the spring 332 is in its natural state, the pulleys 321 are higher than the support wheel 31. At the same time, the frame rod 3 is also equipped with a limiting member for restricting the sliding of the bias rod 32 in the vertical direction. Therefore, when the limiting member is not released, the cylindrical section 7 is supported by the pulleys 321 and slides along the length direction of the frame rod 3, allowing the cylindrical section 7 to slide more smoothly.

[0043] In this embodiment, the limiting component includes a first stop bar 331 and a second stop bar 41. The first stop bar 331 is fixedly connected to the first limiting block 33, and the first limiting block 33 is slidably connected to the support rod 3 along the length direction of the support rod 3. The support rod 3 is also provided with a second spring 47, one end of which is fixedly connected to the support rod 3, and the other end of which is fixedly connected to the first limiting block 33. When the second spring 47 is in its natural state, the first stop bar 331 is located below the offset rod 32. The second stop bar 41 is fixedly connected to the second limiting block 34, and the second stop bar 41 passes through the offset rod 32 in the vertical direction. The end of the second stop bar 41 near the offset rod 32 is provided with a locking block 42. The offset rod 32 is provided with an abutment groove 43 for the locking block 42 to slide, and the end of the abutment groove 43 near the support rod 1 is provided with an unlocking hole 44 for the locking block 42 to pass through in the vertical direction.

[0044] When the cylinder 45 and the second limiting block 34 push the cylinder section 7 against the first limiting block 33, the second spring 47 is compressed, and the first stop rod 331 begins to disengage from the bias rod 32. When the cylinder section 7 reaches a certain position, the locking block 42 aligns with the unlocking hole 44, and the first stop rod 331 and the second stop rod 41 completely disengage from the bias rod 32. The bias rod 32 begins to descend under the gravity of the cylinder section 7 transmitted from the pulley 321, and then the cylinder section 7 is mounted on the support wheel 31.

[0045] Meanwhile, in order to position the cylinder sections 7 of different lengths, the stop bar 331 is set as a telescopic bar. The stop bar 331 can extend and retract in the length direction of the support bar 3. At the same time, the stop bar 331 is also equipped with bolts to limit its own extension and retraction.

[0046] The implementation principle of the auxiliary processing device for welding wind turbine towers in this application embodiment is as follows: Before welding the tower, a section 7 needs to be placed on the positioning device 5 below the support rod 3 by a hoisting device, and the section 7 needs to maintain a certain distance from the support rod 3; then, another section 7 is directly sleeved on the pulleys 321 of the two support rods 3 in the horizontal direction by the hoisting device; the sliding seat 341 is driven to slide towards the first limiting block 33 by the pressing cylinder 45. During the sliding of the sliding seat 341, the gear 37 meshes with the rack 38 and rotates. Under the action of the torsion spring 39, the second limiting block 34 will also rotate and gradually change to a vertical state. Interference between 341 and magnet 46 prevents it from rotating further; it then continues to move forward to abut against the cylindrical section 7, pushing the cylindrical section 7 towards the first limiting block 33; when the cylindrical section 7 reaches a certain position, the locking block 42 aligns with the unlocking hole 44, and the first stop bar 331 and the second stop bar 41 are completely disengaged from the bias rod 32. The bias rod 32 begins to descend under the gravity of the cylindrical section 7 transmitted from the pulley 321, and then the cylindrical section 7 is mounted on the support wheel 31; then the hydraulic cylinder 11 drives the sliding rod 2 to slide down and places the cylindrical section 7 on the positioning device 5, and then the existing cylindrical section 7 on the positioning device 5 is pushed over by the push roller on the positioning device 5, so that the two cylindrical sections 7 abut against each other.

[0047] Finally, the motor 65 drives the lead screw 64 to rotate, thereby driving the welding machine 62 to slide up and down and move to the welding bevel. The positioning device 5 drives the two cylindrical sections 7 to rotate, and at the same time, the welding machine 62 starts to work and perform welding. After welding is completed, the cylindrical section 7 is taken out from the support rod 3 in the horizontal direction by the push roller on the positioning device 5. Then, the hydraulic cylinder 11 lifts the slide rod 2 and the support rod 3 again, and the lifting device puts the cylindrical section 7 back onto the support rod 3. Repeating the above steps can complete the welding of the tower.

[0048] The above are all preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
