Description

Technical Field

[0001] The present application relates to the technical field of wind power tower installation welding, and in particular to a high-efficiency and intelligent submerged arc welding device for wind power towers. Background Art

[0002] Wind turbine tower is the tower pole of wind power generation. It mainly plays a supporting role in wind turbine generator sets and absorbs the vibration of the set. Wind turbine tower is generally composed of multiple sections. In order to facilitate installation, two small sections are usually welded into a large section in the workshop (usually using submerged arc welding, which is a method of welding with arc burning under the flux layer, and has stable inherent welding quality and high welding productivity). The large section is then transported to the preset location for tower installation, and then installed in sequence. Because the large section is connected in sections by small sections, as more small sections are connected, the weight of the large section increases, and the friction resistance between the section and the roller increases, which may cause the roller to be unable to drive the section to rotate;

[0003] After searching the invention with patent publication number CN117206770A, it is disclosed that a wind power tower barrel section welding auxiliary device is provided, wherein a main rotating part and an auxiliary rotating part are rotatably arranged on a workbench, and the auxiliary rotating part comprises an outer ring of a bearing and an inner ring of a bearing, wherein the outer ring of the bearing is fixedly arranged on the workbench, and the inner ring of the bearing is rotatably arranged in the outer ring of the bearing, and the inner ring of the bearing is matched with the outer ring of the bearing, and the traction is carried out by the matching of the traction motor, the gear and the gear ring, thereby driving the tower barrel to rotate, although it can meet the requirements of the inner wall and the outer wall There is a need for ring welding, but the placement and removal of the tower require the tower to pass coaxially through the main rotating part and the auxiliary rotating part. Since the tower itself is large in size and its own material is heavy, the tower moving slot is hoisted by a gantry, which makes it difficult to pass coaxially from the main rotating part and the auxiliary rotating part during installation or removal, and it is also necessary to overlap and align the two ends of the cylinder to be welded during placement, which has the problem of inconvenient installation and affects its welding efficiency.

DETAILED DESCRIPTION

[0034] In order to make the purpose, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application.

[0035] like Figure 1-Figure 10 As shown, an embodiment of the present application proposes a wind power tower submerged arc welding efficient intelligent welding device, comprising:

[0036] A base 1, with brackets 2 at both ends of the top, two supporting columns 3 are rotatably arranged on the two brackets 2, the two supporting columns 3 are arranged horizontally and parallel, the distance between the two supporting columns 3 is smaller than the diameter of the tower to be welded, and the tower can be placed horizontally on the two supporting columns 3;

[0037] Two moving seats 4 are provided with a slide rail 5 on the base 1. The two moving seats 4 are slidably sleeved on the slide rail 5. The base 1 is provided with a driving member 13 for driving the two moving seats 4 to slide synchronously in the opposite direction. A mounting cylinder 6 is rotatably provided on the moving seat 4. An inner support member 7 is provided on the mounting cylinder 6. The inner support member 7 is used to fix or release the tower. When welding the tower, the two towers are placed on the two supporting columns 3 through the gantry crane device. The setting of the supporting column 3 can not only support the tower, but also quickly align the two towers to be welded coaxially. When the two towers are placed, The driving member 13 drives the two moving seats 4 to move synchronously in opposite directions. When the two moving seats 4 are close to each other and respectively contact the two towers, the towers are fixed by the inner support member 7. The two supporting columns 3 mainly support the towers. The inner support member 7 only connects the towers with the mounting tubes 6. The two mounting tubes 6 are fixed with gear rings 8. A guide rod 9 is rotatably arranged on the base 1. Two first gears 10 are fixed on the guide rod 9 and the two first gears 10 are respectively meshed with the teeth of the two gear rings 8. One end of the guide rod 9 is connected to a first motor 11 arranged on the base 1. Preferably, as Figure 3 As shown, the axial length of the first gear 10 is longer than the axial length of the gear ring 8. Therefore, even if the moving seat 4 slides horizontally, the first gear 10 and the gear ring 8 always remain in a meshing state. When the inner support members 7 on both sides are respectively fixed to the two towers, the first motor 11 works, and its output shaft drives the guide rod 9 to rotate, and the teeth of the two first gears 10 and the two gear rings 8 are meshed, thereby driving the two installation cylinders 6 to rotate synchronously. Since the two supporting columns 3 are rotatably connected and support the two towers, the two inner support members 7 connect the two towers to the two installation cylinders 6 respectively, thereby driving the two towers to rotate synchronously.

[0038] The welding member 12 is arranged on the base 1 through the adjusting member 22. Under the driving of the adjusting member 22, the welding member 12 can perform girth welding on the inner wall or outer wall of the tower. The two towers are supported by the supporting column 3. The ends of the two towers that are away from each other are fixed by the inner support member 7, so that the inner and outer walls of the ends of the two towers that overlap each other are not blocked. Under the driving of the adjusting member 22, the welding member 12 can be placed on the outer wall of the overlapped ends of the two towers or on the inner wall of the overlapped ends of the two towers. When the two towers rotate synchronously, the inner wall or the outer wall can be girth welded;

[0039] In this solution, two horizontally parallel supporting columns 3 are used to support the tower. The tower can be directly hoisted on the supporting columns 3 by a gantry crane. There is no obstruction around during hoisting. After the hoisting is placed, the two moving seats 4 are adjusted to be close to each other, and the ends of the two towers that are away from each other are fixed to the two mounting tubes 6 respectively by the inner support 7. The first motor 11 drives the guide rod 9 to rotate. Under the rotation support of the supporting column 3 and the meshing of the first gear 10 and the gear ring 8, the two towers are driven to rotate synchronously. The tower not only rotates stably, thereby ensuring the quality of the ring welding, but also the tower is more convenient to install before or after welding, which reduces the time delayed by installation, improves welding efficiency, and thus improves practicality.

[0040] like Figure 5 and Fig.10As shown, in some embodiments, the inner support member 7 includes an adjusting ring 701 coaxially sleeved on the mounting tube 6, a plurality of annularly distributed oblique grooves 702 are provided on the adjusting ring 701, a support plate is configured on the outer side wall of the adjusting ring 701, the oblique grooves 702 are provided on the support plate, a plurality of annularly distributed straight grooves 703 are provided on the mounting tube 6, a slider 704 is slidably provided in the straight groove 703, an inner support plate 705 is provided on one side of the slider 704, and a support rod 706 whose end portion movably passes through the oblique groove 702 is provided on the other side, and the outer side of the adjusting ring 701 is provided with a plurality of annularly distributed straight grooves 703, and a plurality of annularly distributed straight grooves 703 are provided on the mounting tube 6, and a plurality of annularly distributed straight grooves 703 are provided with a slider 704. An arc-shaped rack 707 is arranged on the peripheral side, and a second motor 708 is arranged on the mounting tube 6. The output shaft of the second motor 708 is provided with a second gear 709 meshing with the teeth of the arc-shaped rack 707. When fixing the tower, the moving seat 4 is first slid close to the tower, and a plurality of inner support plates 705 are inserted into the tower. The second motor 708 works, and its output shaft drives the second gear 709 to rotate. Under the meshing of the teeth of the second gear 709 and the arc-shaped rack 707, the adjusting ring 701 is driven to rotate. When the adjusting ring 701 rotates, The inclined groove 702 applies a certain oblique resistance force to the support rod 706, thereby forcing the support rod 706 to slide obliquely along the inclined groove 702, thereby driving the slider 704 to slide along the straight groove 703. The plurality of sliders 704, the straight groove 703 and the inclined groove 702 are all distributed in an annular shape. Therefore, when the adjusting ring 701 rotates, the plurality of sliders 704 are driven to synchronously slide close to the center of the mounting tube 6 or synchronously slide away from the center of the mounting tube 6. When the plurality of sliders 704 synchronously slide away from the center of the mounting tube 6, the plurality of inner support plates 7 05 expands away synchronously, thereby abutting and overlapping the inner wall of the tower, and utilizing the abutting friction force to fix the tower and the mounting tube 6. When a plurality of sliders 704 slide synchronously close to the center of the mounting tube 6, a plurality of inner support plates 705 contract synchronously close to each other, thereby releasing the abutting and overlapping against the inner wall of the tower, thereby releasing the fixation of the tower and the mounting tube 6. It should be noted that the mounting tube 6 is coaxial with the tower placed on the supporting column 3. Therefore, when fixing or releasing the fixation, the tower does not need to move non-axially, which makes it easier for the two towers to dock.

[0041] like Figure 6 , Figure 7 and Fig. 9As shown, in some embodiments, an outer sleeve 14 is sleeved on the supporting column 3, and a plurality of rolling grooves 15 distributed in an annular shape are opened on the outer surface of the supporting column 3. A plurality of groups of balls 16 are rollingly inserted on the inner wall of the outer sleeve 14, and the plurality of groups of balls 16 are rollingly inserted in the plurality of rolling grooves 15 respectively. Through the sleeved outer sleeve 14, the balls 16 are set and the balls 16 and the rolling grooves 15 are rollingly matched, so that the outer sleeve 14 can not only rotate synchronously with the supporting column 3, but also the outer sleeve 14 can slide axially on the supporting column 3, and the sliding is smooth, so that when hoisting the tower, the tower can be directly placed on the two outer sleeves 14, even if the two towers are not overlapped during the placement process, it will not be affected (in the hoisting process, in order to facilitate the removal of hoisting ropes or hooks, it is better to reserve a little gap between the two towers). When the two movable seats 4 are close to each other, the outer sleeve 14 can slide along the supporting column 3, and the two towers can be quickly docked to ensure the subsequent ring welding quality.

[0042] like Fig. 9 As shown, in some embodiments, both ends of the supporting column 3 are coaxially connected with a third gear 17, and the two third gears 17 are respectively meshed with the teeth of the two gear rings 8. Preferably, the axial length of the third gear 17 is longer than the axial length of the gear ring 8, so that when the two movable seats 4 are approaching or moving away from each other (referring to the distance when fixing the tower or releasing the tower), the third gear 17 and the gear ring 8 can maintain a meshing state, and when the mounting cylinder 6 rotates, the teeth of the third gear 17 and the gear ring 8 are meshed, thereby driving the supporting column 3 to rotate, so that the rotation of the supporting column 3 is not only dependent on the rotation of the tower (passive rotation), it can actively rotate and actively apply a rotational thrust to the tower, so that the rotation of the tower is more stable and stable, so as to ensure the quality of the ring welding.

[0043] like Figure 1 and Figure 8 As shown, in some embodiments, a mounting seat 18 is provided on the base 1, and pressure arms 19 are hinged at both ends of the mounting seat 18, and pressure wheels 20 are rotatably provided at the ends of the two pressure arms 19 away from the hinge point, and a driving member 21 for driving the two pressure arms 19 to rotate synchronously in the opposite direction around the hinge point is provided on the mounting seat 18. When the tower is placed on the two supporting columns 3, the two supporting columns 3 apply a supporting resistance force to the tower from the bottom, and the two pressure arms 19 are driven by the driving member 21 to rotate around the hinge point through the two pressure arms 19. The two pressure wheels 20 roll against the two sides of the tower by synchronously rotating in opposite directions. The two pressure wheels 20 and the supporting column 3 form a three-point rolling contact, and the three points form a triangle. It should be noted that the two pressure wheels 20 just come into contact with the overlapping points of the two towers. The rolling pressure of the pressure wheels 20 not only presses the overlapping points of the two towers, but also presses one end of the two towers away from the inner support member 7 to ensure that when the two towers rotate, their overlapping ends rotate smoothly and the two towers are neatly butted to ensure the ring welding effect.

[0044] like Figure 8 As shown, in some embodiments, the driving member 21 includes a first bidirectional screw rod 2101 rotatably arranged on the mounting seat 18, and both ends of the first bidirectional screw rod 2101 are threadedly sleeved with movable blocks 2102. Preferably, the movable blocks 2102 overlap the mounting seat 18, and the two movable blocks 2102 are fixedly provided with spur racks 2103. The hinge shafts of the two pressure arms 19 are fixedly provided with fourth gears 2104, and the two fourth gears 2104 are respectively meshed with the teeth of the two spur racks 2103. One end of the first bidirectional screw rod 2101 is connected to a screw rod 2102 arranged on the base 18. The third motor 2105 on the tower does work, and its output shaft drives the first bidirectional screw rod 2101 to rotate. Under the action of the bidirectional thread, the two movable blocks 2102 are driven to move synchronously in opposite directions, so that the two fourth gears 2104 are respectively engaged with the teeth of the two spur racks 2103, thereby driving the pressure arm 19 to rotate along its hinge axis. When placing the tower, the two pressure arms 19 are spread apart and will not affect the normal lifting of the tower. After the lifting, the two pressure arms 19 are brought closer together, so that the two pressure wheels 20 roll on the tower.

[0045] like Figure 3 As shown, in some embodiments, the driving member 13 includes a second bidirectional screw rod 1301 rotatably disposed on the base 1, one end of the second bidirectional screw rod 1301 is connected to a fourth motor 1302 disposed on the base 1, and the two moving seats 4 are respectively threadedly sleeved on the two ends of the second bidirectional screw rod 1301. The fourth motor 1302 performs work, and its output shaft drives the second bidirectional screw rod 1301 to rotate. Under the action of the bidirectional thread and the sliding limit of the slide rail 5, the two moving seats 4 are driven to slide synchronously in the opposite directions.

[0046] like Figure 2 and Figure 4As shown, in some embodiments, the adjustment member 22 includes a translation plate 2201, a plug-in slot is provided on one side of the base 1, the translation plate 2201 is slidably inserted in the plug-in slot, two vertical rods 2202 are provided on the translation plate 2201, and a lifting plate 2203 is slidably sleeved on the two vertical rods 2202. A multi-stage hydraulic rod 2204 is connected between the lifting plate 2203 and the translation plate 2201, and a cross bar 2205 is connected to one side of the lifting plate 2203. The weldment 12 is connected to the free end of the cross bar 2205. When hoisting the tower, the translation plate 2201 is first slid to move the weldment 12 away from the supporting column 3. When the tower is hoisted, the translation plate 2201 is moved to reset. According to the welding requirements of internal or external welding, the height of the lifting plate 2203 can be adjusted by the multi-stage hydraulic rod 2204. When welding externally, the translation plate 2201 is directly slid so that the welding piece 12 is directly located above the overlapping ends of the two towers, and the height of the lifting plate 2203 is adjusted so that the welding gun head of the welding piece 12 is close to the tower. When welding internally, the height of the lifting plate 2203 is also adjusted, and the welding piece 12 and the cross bar 2205 are placed into the tower from one of the mounting tubes 6, and the inner ring welding can be carried out.

[0047] like Figure 4 As shown, in some embodiments, a threaded rod 23 is rotatably provided on the base 1, one end of the threaded rod 23 is connected to a fifth motor 24 provided on the base 1, and a translation plate 2201 is threadedly sleeved on the threaded rod 23, and a wheel 25 is connected to the bottom end of the translation plate 2201. The fifth motor 24 performs work, and its output shaft drives the threaded rod 23 to rotate. Under the action of the thread and the sliding limit of the plug-in slot, the translation plate 2201 is driven to translate, making it more convenient and quick to adjust the position of the welding gun. Preferably, the wheel 25 is located at one end of the translation plate 2201 away from the base 1 and below the vertical rod 2202. When the translation plate 2201 is moving, the wheel 25 rolls and overlaps with the ground, thereby supporting the translation plate 2201 to ensure the stability of the translation plate 2201 after movement.

[0048] like Fig.10 As shown, in some embodiments, the inner support plate 705 is constructed as an arc-shaped plate and a rubber pad 26 is provided on its outer wall. A reinforcing rib is connected between the inner support plate 705 and the slider 704. The inner support plate 705 is in an arc-shaped structure for increasing its contact area with the inner wall of the tower. The rubber pad 26 is provided for increasing the friction between the inner support plate 705 and the inner wall of the sleeve. The reinforcing rib is connected for increasing the supporting strength of the inner support plate 705, thereby improving the stability of the inner support plate 705 in fixing the tower, ensuring that it is not easy to slip after internal support, thereby ensuring the stability of the tower rotation, and ensuring the quality of the ring welding.
