Description

Technical Field

[0001] The invention belongs to the technical field of flange assembly welding and relates to an assembly welding device, in particular to an assembly welding device for a flange of a concrete-steel composite wind power tower. Background Art

[0002] In recent years, the scale of domestic wind power construction has been large and the development has been rapid. The wind power tower industry has gradually developed towards large-scale, heavy-duty and diversified development. Wind power tower is an important component of wind power generation equipment.

[0003] The wind turbine tower is an important supporting and load-bearing component of the wind power generation equipment. This component bears wind disasters, earthquakes, extreme climate conditions and alternating operating loads. The quality of the weld between the wind turbine tower barrel section and the flange ring plays a key role in the service life of the tower. The existing assembly welding device generally directly welds the barrel section to the flange ring. Before welding the barrel section, the weld position needs to be cleaned and some impurities such as oil, paint, water and rust need to be removed. This can effectively ensure the sealing of the weld joint. Summary of the invention

[0004] The purpose of the present invention is to address the above-mentioned problems in the prior art and to propose a concrete steel structure composite wind power tower flange assembly welding device. The technical problem to be solved by the invention is: how to effectively remove impurities from the weld of the cylinder section.

[0005] The purpose of the present invention can be achieved by the following technical solutions:

[0006] A concrete steel structure composite wind power tower flange assembly welding device comprises a base, a first cavity is opened inside the base, a clamping assembly is arranged on the base, a slide groove is opened on the base, a clamping drive assembly is arranged on the slide groove, support columns are fixed on both sides of the base, a connecting box is fixed on the upper end of the supporting column, a sliding column is slidably connected between the two connecting boxes, a first electric telescopic rod is fixed inside the connecting box, the other end of the first electric telescopic rod is fixedly connected to the sliding column, a first opening for the sliding column to move is opened on the connecting box, a welding assembly is arranged on the lower side of the connecting box, a second electric telescopic rod is fixed on the lower side of the sliding column, an assembly assembly is arranged on the other end of the second electric telescopic rod, a grinding assembly is arranged below the assembly assembly, the grinding assembly can interfere with the clamping drive assembly, and a second opening for the grinding assembly to extend into the first cavity is opened on the base.

[0007] The working principle of the present invention is as follows: During use, the cylinder section is horizontally placed on the base, and then the sliding column is moved by the extension of the first electric telescopic rod. The sliding column drives the second electric telescopic rod to move. The second electric telescopic rod drives the grinding assembly to approach the cylinder section through the assembly component, so that the grinding assembly drives the clamping assembly through the clamping drive component, and the clamping assembly fixes the cylinder section. Then, the grinding assembly abuts against the cylinder section, and the weld of the cylinder section is ground. After grinding, the sliding column moves in the reverse direction by the contraction of the first electric telescopic rod, so that the grinding assembly moves away from the cylinder section, and the cylinder section is released from fixation. Then, the assembly component drives the grinding assembly into the first cavity by the extension of the second electric telescopic rod. Then, the flange is placed on the assembly component, and the sliding column is moved by the extension of the first electric telescopic rod, so that the assembly component cooperates with the cylinder section. Then, the flange and the cylinder section are welded by the welding component. In this way, impurities at the weld of the cylinder section are effectively removed, the sealing performance of the weld butt joint is effectively guaranteed, the welding quality of the cylinder section and the flange is improved, the efficiency of subsequent production is improved, and manual grinding is avoided, thus avoiding the waste of labor costs.

[0008] The grinding assembly includes a grinding cylinder, which is connected to the assembly component through a connecting column. A contact rod is fixed at the lower end of the grinding cylinder, and the contact rod can abut against the clamping drive component. A first rotating motor is fixed on the inner wall of the grinding cylinder, and a first turntable is fixed at the output shaft end of the first rotating motor. The first turntable is slidably connected to the inner wall of the grinding cylinder. A second cavity is opened inside the turntable, and a third opening is opened on the first turntable. Two extrusion blocks are slidably connected to the first turntable, and the extrusion blocks extend into the second cavity. Two groups of elastic components are arranged on the inner wall of the first turntable, and the two extrusion blocks are respectively connected to the two groups of elastic components. Two first connecting rods are rotatably connected to the extrusion blocks, and a first grinding block and a second grinding block are respectively rotatably connected to the two first connecting rods. The extrusion block is located between the first grinding block and the second grinding block, and the first grinding block and the second grinding block extend out of the inside of the first turntable and are slidably connected to the first turntable.

[0009] With the above structure, when the grinding cylinder approaches the cylinder section, the contact rod drives the clamping assembly to fix the cylinder section through the clamping drive component. As the grinding cylinder continues to approach the cylinder section, the cylinder section abuts against the extrusion block, causing the extrusion block to move into the second cavity. The extrusion block makes the first grinding block and the second grinding block move relative to each other through the two first connecting rods, so that the first grinding block abuts against the outer circumference of the cylinder section, and the second grinding block abuts against the inner circumference of the cylinder section. Then, the first rotating motor drives the first turntable to rotate, and the first turntable drives the first grinding block and the second grinding block to rotate, so that the weld of the cylinder section is ground. In this way, manual grinding is avoided, labor costs are saved, the grinding efficiency is improved, and the linkage of the device is also improved.

[0010] The clamping assembly includes a connecting seat. A number of groups of arc-shaped clamping seats are slidably connected to the base. Each group of arc-shaped clamping seats includes two arc-shaped clamping seats. The two arc-shaped clamping seats are respectively located on both sides of the sliding groove and correspond to each other one by one. The lower end of the arc-shaped clamping seat extends into the first cavity. The arc-shaped clamping seat is rotatably connected to the third connecting rod through the second connecting rod. The third connecting rod is fixedly connected to the connecting seat. The connecting seat is fixedly connected to the inner wall of the base through the second telescopic rod. A second spring is sleeved on the second telescopic rod. The two ends of the second spring are respectively fixedly connected to the inner wall of the base and the connecting seat. The connecting seat abuts against the clamping driving assembly.

[0011] With the above structure, when the clamping driving assembly abuts against the connecting seat, the connecting seat moves downward, causing the second telescopic rod to contract. The connecting seat drives the second connecting rod to move through the third connecting rod, and the second connecting rod drives the two arc-shaped clamping seats to move relatively, so that the cylinder section is clamped and fixed. In this way, when the cylinder section is polished, the cylinder section will not shift.

[0012] The clamping driving assembly includes a conical abutting block. A sliding rod is slidably connected to the sliding groove. The sliding rod abuts against the abutting rod. The sliding rod is fixedly connected to the conical abutting block. The conical abutting block is located in the first cavity. The conical abutting block abuts against the connecting seat. A elastic force assembly is arranged on the conical abutting block.

[0013] With the above structure, when the polishing cylinder approaches the cylinder section, the abutting rod drives the conical abutting block to move through the sliding rod, making the conical abutting block abut against the connecting seat, so that the arc-shaped clamping seats clamp and fix the cylinder section. When the polishing cylinder moves away from the cylinder section, the polishing cylinder drives the abutting rod to move away from the sliding rod. Under the action of the elastic force assembly, the conical abutting block moves away from the connecting seat, causing the arc-shaped clamping seats to release the fixation of the cylinder section.

[0014] The elastic force assembly includes a third telescopic rod. The conical abutting block is fixedly connected to the third telescopic rod through a connecting plate. The other end of the third telescopic rod is fixedly connected to the second telescopic rod. A third spring is sleeved on the third telescopic rod. The two ends of the third spring are respectively fixedly connected to the second telescopic rod and the connecting plate. A second spring is sleeved on the telescopic end of the second telescopic rod. The two ends of the second spring are respectively fixedly connected to the second telescopic rod and the connecting seat.

[0015] With the above structure, when the abutting rod moves away from the sliding rod, under the action of the third spring, the connecting plate drives the conical abutting block to move towards the abutting rod, making the conical abutting block move away from the connecting seat. At this time, under the action of the second spring, the connecting seat moves upward, so that the arc-shaped clamping seats release the fixation of the cylinder section. In this way, the cylinder section can be quickly released from fixation without manual operation, improving the linkage of the device.

[0016] The assembly component includes an assembly cylinder, which is fixedly connected to the connecting column. The second electric telescopic rod is fixedly connected to the assembly cylinder. A second rotating motor is fixed on the inner wall of the assembly cylinder. The output shaft end of the second rotating motor is fixed with a second turntable. A third cavity is formed inside the second turntable. Two fixed seats are fixed on the inner wall of the second turntable. Each fixed seat is rotatably connected with an L-shaped rod. The adjacent ends of the two L-shaped rods are respectively rotatably connected with two fourth connecting rods. The fourth connecting rod is rotatably connected with a second jaw. A third electric telescopic rod is fixed between the two second jaws. The other end of the L-shaped rod is rotatably connected with a first jaw. A fourth opening is formed on the second turntable. The first jaw and the second jaw extend out of the inside of the second turntable and are slidably connected to the second turntable. A limiting block is fixed on the second turntable, and the limiting block is located between the first jaw and the second jaw.

[0017] With the above structure, when the grinding cylinder completely enters the first cavity, place the flange on the assembly cylinder. Through the cooperation of the first jaw and the limiting block, the flange is preliminarily fixed. Then, the first electric telescopic rod drives the second electric telescopic rod to move through the sliding column, so that the assembly cylinder approaches the cylinder section. When the end face of the cylinder section abuts against the limiting block, the third electric telescopic rod extends, causing the two second jaws to move away from each other, so that the cylinder section is fixed. At the same time, the second jaw drives one end of the L-shaped rod to move towards the second rotating motor through the fourth connecting rod. Under the action of the fixed seat, the other end of the L-shaped rod drives the first jaw to move towards the second jaw, so that the flange abuts against the outer circumference of the cylinder section, and the flange is fixed. Then, the second rotating motor drives the second rotating shaft to drive the second turntable to rotate, so that the flange and the cylinder section rotate together. Then, the flange and the cylinder section are welded through the welding component. In this way, the flange and the cylinder section abut and are relatively fixed, which is convenient for the welding component to weld them when the flange and the cylinder section rotate synchronously, improving the welding efficiency and the quality of the weld seam.

[0018] The elastic component includes a plurality of first telescopic rods, which are fixed between the inner wall of the first turntable and the extrusion block. A first spring is sleeved on the first telescopic rod, and the two ends of the first spring are respectively fixedly connected to the extrusion block and the inner wall of the first turntable.

[0019] With the above structure, when the grinding cylinder moves away from the cylinder section, under the action of the first spring, the extrusion block moves closer to the cylinder section, so that the first grinding block and the second grinding block move away from the cylinder section. In this way, it is convenient for the grinding cylinder to quickly disengage from the cylinder section, saving time for subsequent production and improving work efficiency.

[0020] A plurality of rollers are rotatably connected to the base.

[0021] With the above structure, the setting of the rollers makes it convenient for the cylinder section to rotate when the second turntable drives the cylinder section to rotate.

[0022] Compared with the prior art, the present flange assembly welding device for a concrete steel structure composite wind power tower has the following advantages:

[0023] 1. During use, place the cylinder section horizontally on the base. Then, extend the first electric telescopic rod to move the sliding column. The sliding column drives the second electric telescopic rod to move. The second electric telescopic rod drives the grinding assembly to approach the cylinder section through the assembly component, so that the grinding assembly drives the clamping component through the clamping drive component, enabling the clamping component to fix the cylinder section. Then, the grinding assembly contacts the cylinder section, and the weld of the cylinder section is ground. After grinding, contract the first electric telescopic rod to move the sliding column in the reverse direction, so that the grinding assembly moves away from the cylinder section, and the cylinder section is released from fixation. Then, extend the second electric telescopic rod to drive the assembly component to bring the grinding assembly into the first cavity. Then, place the flange on the assembly component. Then, extend the first electric telescopic rod to move the sliding column, so that the assembly component cooperates with the cylinder section. Then, through the welding component, weld the flange and the cylinder section. In this way, impurities at the weld of the cylinder section are effectively removed, the sealing performance of the weld butt joint is effectively guaranteed, the welding quality of the cylinder section and the flange is improved, the efficiency of subsequent production is increased, and manual grinding is also avoided, thus preventing waste of labor costs.

[0024] 2. When the grinding cylinder approaches the cylinder section, the contact rod drives the clamping component to fix the cylinder section through the clamping drive component. As the grinding cylinder continues to approach the cylinder section, the cylinder section contacts the extrusion block, causing the extrusion block to move into the second cavity. The extrusion block makes the first grinding block and the second grinding block move relative to each other through two first connecting rods, so that the first grinding block contacts the outer circumference of the cylinder section and the second grinding block contacts the inner circumference of the cylinder section. Then, drive the first turntable to rotate through the first rotary motor. The first turntable drives the first grinding block and the second grinding block to rotate, thereby grinding the weld of the cylinder section. In this way, manual grinding is avoided, labor costs are saved, the grinding efficiency is improved, and the linkage of the device is also improved.

[0025] 3. When the contact rod moves away from the sliding rod, under the action of the third spring, the connecting plate drives the conical contact block to move towards the contact rod, causing the conical contact block to move away from the connecting seat. At this time, under the action of the second spring, the connecting seat moves upward, so that the arc-shaped clamping seat releases the fixation of the cylinder section. In this way, the cylinder section can be quickly released from fixation without manual operation, improving the linkage of the device.

[0026] 4. When the grinding cylinder completely enters the first cavity, place the flange on the assembly cylinder. Through the cooperation of the first clamping jaw and the limiting block, the flange is preliminarily fixed. Then, the first electric telescopic rod drives the second electric telescopic rod to move through the sliding column, so that the assembly cylinder approaches the cylinder section. When the end face of the cylinder section abuts against the limiting block, the third electric telescopic rod extends, causing the two second clamping jaws to move away from each other, so that the cylinder section is fixed. At the same time, the second clamping jaw drives one end of the L rod to move towards the second rotating motor through the fourth connecting rod. Under the action of the fixed seat, the other end of the L rod drives the first clamping jaw to move towards the second clamping jaw, so that the flange abuts against the outer circumference of the cylinder section, and the flange is fixed. Then, the second rotating motor drives the second rotating shaft to drive the second turntable to rotate, so that the flange and the cylinder section rotate together. Then, the flange and the cylinder section are welded through the welding assembly. In this way, the flange and the cylinder section abut and are relatively fixed, which is convenient for the welding assembly to weld them when the flange and the cylinder section rotate synchronously, improving the welding efficiency and the quality of the weld seam.

A connection box 6 is fixed at the upper end of the support column 10. A sliding column 8 is slidably connected between the two connection boxes 6. A first electric telescopic rod 7 is fixed inside the connection box 6. The other end of the first electric telescopic rod 7 is fixedly connected to the sliding column 8. A first opening for the sliding column 8 to move is provided on the connection box 6. A welding assembly 9 is arranged below the connection box 6. A second electric telescopic rod 11 is fixed below the sliding column 8. An assembly component is arranged at the other end of the second electric telescopic rod 11. A grinding component is arranged below the assembly component. The grinding component can abut against the clamping driving component. A second opening for the grinding component to extend into the first cavity is provided on the base 1.

[0036] During use, the cylinder section is horizontally placed on the base 1. Then, the first electric telescopic rod 7 extends to move the sliding column 8. The sliding column 8 drives the second electric telescopic rod 11 to move. The second electric telescopic rod 11 drives the grinding component to approach the cylinder section through the assembly component, so that the grinding component drives the clamping component through the clamping driving component, and the clamping component fixes the cylinder section. Then, the grinding component abuts against the cylinder section, and the weld joint of the cylinder section is ground. After grinding, the first electric telescopic rod 7 contracts to move the sliding column 8 in the reverse direction, so that the grinding component moves away from the cylinder section, and the cylinder section is released from fixation. Then, the second electric telescopic rod 11 extends, so that the assembly component drives the grinding component into the first cavity. Then, the flange is placed on the assembly component. Then, the first electric telescopic rod 7 extends to move the sliding column 8, so that the assembly component cooperates with the cylinder section. Then, the flange and the cylinder section are welded through the welding assembly 9. In this way, impurities at the weld joint position of the cylinder section are effectively removed, the sealing performance of the weld joint butt joint is effectively guaranteed, the welding quality of the cylinder section and the flange is improved, the efficiency of subsequent production is improved, and manual grinding is also avoided, resulting in waste of labor costs.

[0037] The grinding assembly includes a grinding cylinder 13, which is connected to the assembly assembly through a connecting column.

A third opening is opened on the first rotating disk 20, and two extrusion blocks are slidably connected to the first rotating disk 20. 15, the extrusion block 15 extends into the second cavity, two groups of elastic components are arranged on the inner wall of the first turntable 20, the two extrusion blocks 15 are respectively connected to the two groups of elastic components, the extrusion block 15 is rotatably connected to two first connecting rods 23, the two first connecting rods 23 are respectively rotatably connected to the first grinding block 14 and the second grinding block 16, the extrusion block 15 is located between the first grinding block 14 and the second grinding block 16, the first grinding block 14 and the second grinding block 16 extend out of the first turntable 20 and are slidably connected to the first turntable 20.

[0038] When the grinding cylinder 13 approaches the cylinder segment, the abutment rod 17 drives the clamping assembly to fix the cylinder segment through the clamping drive assembly. As the grinding cylinder 13 continues to approach the cylinder segment, the cylinder segment abuts against the extrusion block 15, causing the extrusion block 15 to move into the second cavity. The extrusion block 15 causes the first grinding block 14 and the second grinding block 16 to move relative to each other through the two first connecting rods 23, causing the first grinding block 14 to abut against the outer periphery of the cylinder segment, and the second grinding block 16 to abut against the inner periphery of the cylinder segment. Then, the first turntable 20 is driven to rotate by the first rotating motor 22, and the first turntable 20 drives the first grinding block 14 and the second grinding block 16 to rotate, so that the cylinder segment weld is polished. This avoids manual polishing, saves labor costs, improves the efficiency of polishing, and improves the linkage of the device.

The conical abutting block 35 abuts against the connecting seat 32. A elastic force assembly is arranged on the conical abutting block 35.

[0042] When the grinding cylinder 13 approaches the cylinder section, the abutting rod 17 drives the conical abutting block 35 to move through the sliding rod 5, so that the conical abutting block 35 abuts against the connecting seat 32, thereby enabling the arc-shaped clamping seat 2 to clamp and fix the cylinder section. When the grinding cylinder 13 moves away from the cylinder section, the grinding cylinder 13 drives the abutting rod 17 to move away from the sliding rod 5. Under the action of the elastic force assembly, the conical abutting block 35 moves away from the connecting seat 32, so that the arc-shaped clamping seat 2 releases the fixation of the cylinder section.

[0044] When the abutting rod 17 moves away from the sliding rod 5, under the action of the third spring 39, the connecting plate 38 drives the conical abutting block 35 to move towards the abutting rod 17, so that the conical abutting block 35 moves away from the connecting seat 32. At this time, under the action of the second spring 33, the connecting seat 32 moves upward, so that the arc-shaped clamping seat 2 releases the fixation of the cylinder section. In this way, the cylinder section can be quickly released from the fixation without manual operation, improving the linkage of the device.

[0045] The assembly component includes an assembly cylinder 12. The assembly cylinder 12 is fixedly connected to the connecting column. The second electric telescopic rod 11 is fixedly connected to the assembly cylinder 12. A second rotating motor 28 is fixed on the inner wall of the assembly cylinder 12.

A limiting block 25 is fixed on the second turntable 27. The limiting block 25 is located between the first clamping jaw 24 and the second clamping jaw 26.

[0046] When the grinding cylinder 13 completely enters the first cavity, place the flange on the assembly cylinder 12. Through the cooperation of the first clamping jaw 24 and the limiting block 25, the flange is preliminarily fixed. Then, the first electric telescopic rod 7 drives the second electric telescopic rod 11 to move through the sliding column 8, so that the assembly cylinder 12 approaches the cylinder section. When the end face of the cylinder section abuts against the limiting block 25, the third electric telescopic rod 18 extends, causing the two second clamping jaws 26 to move away from each other, so that the cylinder section is fixed. At the same time, the second clamping jaw 26 drives one end of the L-shaped rod 30 to move towards the second rotating motor 28 through the fourth connecting rod. Under the action of the fixed seat 29, the other end of the L-shaped rod 30 drives the first clamping jaw 24 to move towards the second clamping jaw 26, so that the flange abuts against the outer periphery of the cylinder section and the flange is fixed. Then, the second rotating motor 28 drives the second rotating shaft to drive the second turntable 27 to rotate, so that the flange and the cylinder section rotate together. Then, the welding assembly 9 welds the flange and the cylinder section. In this way, the flange and the cylinder section abut against each other and are relatively fixed, which is convenient for the welding assembly 9 to weld them when the flange and the cylinder section rotate synchronously, improving the welding efficiency and the quality of the weld seam.

A first spring 21 is sleeved on the first telescopic rod 19. The two ends of the first spring 21 are respectively fixedly connected to the extrusion block 15 and the inner wall of the first turntable 20.

[0048] When the grinding cylinder 13 moves away from the cylinder section, under the action of the first spring 21, the extrusion block 15 moves closer to the cylinder section, so that the first grinding block 14 and the second grinding block 16 move away from the cylinder section. In this way, it is convenient for the grinding cylinder 13 to quickly disengage from the cylinder section, saving time for subsequent production and improving work efficiency.

[0049] A plurality of rollers 3 are rotatably connected to the base 1.

[0050] The setting of the rollers 3 makes it convenient for the cylinder section to rotate when the second turntable 27 drives the cylinder section to rotate.

[0051] Working principle of the present invention: During use, place the cylinder section horizontally on the roller 3, and then extend the first electric telescopic rod 7 to move the sliding column 8. The sliding column 8 drives the second electric telescopic rod 11 to move. The second electric telescopic rod 11 drives the connecting column to move through the assembly cylinder 12. The connecting column drives the grinding cylinder 13 to approach the cylinder section. The contact rod 17 drives the conical contact block 35 to move through the sliding rod 5, so that the conical contact block 35 contacts the connecting seat 32. The connecting seat 32 moves downward, causing the second telescopic rod 31 to contract. The connecting seat 32 drives the second connecting rod 34 to move through the third connecting rod 36. The second connecting rod 34 drives the two arc-shaped clamping seats 2 to move relatively, so that the cylinder section is clamped and fixed. As the grinding cylinder 13 continues to approach the cylinder section, the cylinder section contacts the extrusion block 15, causing the extrusion block 15 to move into the second cavity. The extrusion block 15 makes the first grinding block 14 and the second grinding block 16 move relatively through the two first connecting rods 23, so that the first grinding block 14 contacts the outer circumference of the cylinder section, and the second grinding block 16 contacts the inner circumference of the cylinder section. Then drive the first turntable 20 to rotate through the first rotating motor 22. The first turntable 20 drives the first grinding block 14 and the second grinding block 16 to rotate, so as to grind the weld of the cylinder section. After grinding, contract the first electric telescopic rod 7 to move the sliding column 8 in the reverse direction, so that the grinding cylinder 13 moves away from the cylinder section. The contact rod 17 moves away from the sliding rod 5. Under the action of the third spring 39, the connecting plate 38 drives the conical contact block 35 to move towards the contact rod 17, so that the conical contact block 35 moves away from the connecting seat 32. At this time, under the action of the second spring 33, the connecting seat 32 moves upward, so that the arc-shaped clamping seat 2 releases the fixation of the cylinder section. Then extend the second electric telescopic rod 11 to make the grinding cylinder 13 completely enter the first cavity. Then place the flange on the assembly cylinder 12 and initially fix the flange through the cooperation of the first clamping jaw 24 and the limiting block 25. Then the first electric telescopic rod 7 drives the second electric telescopic rod 11 to move through the sliding column 8, so that the assembly cylinder 12 approaches the cylinder section. When the end face of the cylinder section contacts the limiting block 25, extend the third electric telescopic rod 18 to make the two second clamping jaws 26 move away from each other, so that the cylinder section is fixed. At the same time, the second clamping jaw 26 drives one end of the L-shaped rod 30 to move towards the second rotating motor 28 through the fourth connecting rod. Under the action of the fixed seat 29, the other end of the L-shaped rod 30 drives the first clamping jaw 24 to move towards the second clamping jaw 26, so that the flange contacts the outer circumference of the cylinder section and the flange is fixed. Then drive the second rotating shaft to drive the second turntable 27 to rotate through the second rotating motor 28, so that the flange and the cylinder section rotate together. Then weld the flange and the cylinder section through the welding assembly 9. After welding, the third electric telescopic rod 18, the first electric telescopic rod 7, and the second electric telescopic rod 11 return to their initial positions in sequence, thus completing the welding.

[0052] In summary, through the cooperation of the grinding assembly and the clamping assembly, the impurities at the weld of the cylinder section are effectively removed.
