Description

TECHNICAL FIELD

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

[0002] The wind power tower is a tower pole for wind power generation, mainly serving as support in a wind turbine generator unit and absorbing vibration of the unit. The wind power tower is generally composed of multiple tower sections. In order to facilitate installation, two small tower sections are usually welded into a large tower section in a workshop (submerged arc welding is usually adopted, which is a welding method in which an electric arc burns under a layer of flux, and has inherent stable welding quality and high welding productivity). Then, the large tower section is transported to a preset installation position of the tower section, and then the large tower section is installed in sequence. Since the large tower section is connected by small tower sections in sections, the more small tower sections are connected, the greater the weight of the large tower section, and the frictional resistance between the tower section and the roller also increases, which may result in the situation that the roller cannot drive the tower section to rotate.

[0003] According to the search of the patent with the publication number CN117206770A, a wind power tower section welding auxiliary device is disclosed, which is provided with a main rotating part and a secondary rotating part rotatingly arranged on a workbench. The secondary rotating part includes a bearing outer ring and a bearing inner ring. The bearing outer ring is fixed on the workbench, and the bearing inner ring is rotatingly arranged in the bearing outer ring. The tower section is driven to rotate through the cooperation of the bearing inner ring and the bearing outer ring, the cooperation of the traction motor, the gear and the gear ring. Although the device can meet the demand for girth welding of the inner side wall and the outer side wall, the placement and removal of the tower section need to pass through the coaxial main rotating part and secondary rotating part. Since the tower section has a large volume and is heavy in material, the tower section is moved through the gantry crane. This makes it difficult to pass through the coaxial main rotating part and secondary rotating part during installation or removal. In addition, the two ends of the tower section to be welded need to be overlapped and aligned during placement. Therefore, the device has the problem of inconvenient installation, which affects the welding efficiency. Therefore, the application provides a high-efficiency intelligent welding device for submerged arc welding of a wind power tower. SUMMARY

[0040] As Figure 5 and Figure 10As shown, in some embodiments, the inner support 7 comprises an adjusting ring 701 coaxially sleeved on the mounting cylinder 6, a plurality of annularly distributed inclined grooves 702 are formed on the adjusting ring 701, the outer side wall of the adjusting ring 701 is configured with a support plate, the inclined grooves 702 are formed on the support plate, a plurality of annularly distributed straight grooves 703 are formed on the mounting cylinder 6, a sliding block 704 is slidingly arranged in the straight grooves 703, an inner support plate 705 is arranged on one side of the sliding block 704, and a support rod 706 movably penetrating the inclined grooves 702 is arranged on the other side of the sliding block 704, an arc-shaped rack 707 is arranged on the outer periphery of the adjusting ring 701, a second motor 708 is arranged on the mounting cylinder 6, an 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 cylinder, first slide the moving seat 4 close to the tower cylinder, and insert the plurality of inner support plates 705 into the tower cylinder, the second motor 708 works, the output shaft drives the second gear 709 to rotate, under the meshing of the second gear 709 and the teeth of the arc-shaped rack 707, the adjusting ring 701 is driven to rotate, when the adjusting ring 701 rotates, the inclined grooves 702 exert a certain inclined resistance on the support rod 706, so as to force the support rod 706 to slide obliquely in the inclined grooves 702, thereby driving the sliding block 704 to slide in the straight grooves 703, the plurality of sliding blocks 704, straight grooves 703 and inclined grooves 702 are annularly distributed, therefore, when the adjusting ring 701 rotates, the plurality of sliding blocks 704 are driven to synchronously slide close to or away from the center of the mounting cylinder 6, when the plurality of sliding blocks 704 synchronously slide away from the center of the mounting cylinder 6, the plurality of inner support plates 705 synchronously expand away, thereby resisting and lapping the inner wall of the tower cylinder, and the resistance friction is utilized, so as to achieve the effect of fixing the tower cylinder and the mounting cylinder 6, when the plurality of sliding blocks 704 synchronously slide close to the center of the mounting cylinder 6, the plurality of inner support plates 705 synchronously contract close, thereby removing the resistance and lapping of the inner wall of the tower cylinder, so as to remove the fixing of the tower cylinder and the mounting cylinder 6, it should be noted that the mounting cylinder 6 is coaxial with the tower cylinder placed on the supporting column 3, therefore, when fixing or removing the fixing, the tower cylinder does not need to move non-axially, which is more convenient for the butt joint of two tower cylinders.

[0041] As Figure 6 , Figure 7 and Figure 9As shown in the drawings, in some embodiments, the outer sleeve 14 is sleeved on the supporting column 3, the outer surface of the supporting column 3 is provided with a plurality of annularly distributed rolling grooves 15, the inner wall of the outer sleeve 14 is rollingly provided with a plurality of groups of rolling balls 16, and the plurality of groups of rolling balls 16 are respectively rollingly provided in the plurality of rolling grooves 15. Through the sleeved outer sleeve 14 and the rolling balls 16 and the rolling grooves 15, the outer sleeve 14 can not only rotate synchronously with the supporting column 3, but also can slide along the supporting column 3 in the axial direction, and the sliding is smooth. When hoisting the tower drum, the tower drum can be directly placed on the two outer sleeves 14, and even if the two tower drums are not overlapped during the placement process (in the hoisting process, a little gap is reserved between the two tower drums for the convenience of taking and placing the hoisting rope or hook), it does not affect the hoisting. When the two moving seats 4 are close to each other, the outer sleeve 14 can slide along the supporting column 3, and the two tower drums can be quickly butt-jointed to ensure the quality of the girth welding.

[0042] As shown in the drawings, Figure 9 In some embodiments, the third gear 17 is coaxially connected to the two ends of the supporting column 3, the two third gears 17 are respectively in gear engagement with the two toothed rings 8, and the axial length of the third gear 17 is preferably longer than the axial length of the toothed ring 8. When the two moving seats 4 are close to or away from each other (referring to the distance between the fixed tower drum and the released tower drum), the third gear 17 and the toothed ring 8 can remain in the gear engagement state. When the installation drum 6 rotates, the third gear 17 and the toothed ring 8 are in gear engagement, thereby driving the supporting column 3 to rotate. The rotation of the supporting column 3 is not only dependent on the rotation of the tower drum (passive rotation), but also can be actively rotated to actively apply a rotating thrust to the tower drum, so that the tower drum rotates more stably to ensure the quality of the girth welding.

After the tower drum is placed on the two supporting columns 3, the two supporting columns 3 apply supporting and abutting forces to the tower drum from the bottom. Through the two pressing arms 19, the driving member 21 drives the two pressing arms 19 to synchronously and reversely rotate around the hinge points, so that the two pressing wheels 20 rollingly abut the two sides of the tower drum. The two pressing wheels 20 and the supporting column 3 form three-point rolling abutment, and the three points form a triangle. It should be noted that the two pressing wheels 20 just abut the overlap points of the two tower drums, and the rolling pressing of the pressing wheels 20 not only presses the overlap points of the two tower drums, but also presses the ends of the two tower drums away from the inner supporting member 7, so as to ensure that the overlap ends rotate stably when the two tower drums rotate, and the two tower drums are butt-jointed in order to ensure the girth welding effect.

[0044] As Figure 8 shown in some embodiments, the driving piece 21 comprises a first bidirectional screw rod 2101 rotatably arranged on the mounting base 18, both ends of the first bidirectional screw rod 2101 are threadedly sleeved with movable blocks 2102, preferably, the movable blocks 2102 are overlapped with the mounting base 18, both the two movable blocks 2102 are fixedly provided with straight racks 2103, both the hinging shafts of the two pressing arms 19 are fixedly provided with fourth gears 2104, the two fourth gears 2104 are respectively engaged with the teeth of the two straight racks 2103, one end of the first bidirectional screw rod 2101 is connected with a third motor 2105 arranged on the base 1, the third motor 2105 works, its output shaft drives the first bidirectional screw rod 2101 to rotate, under the action of the bidirectional thread, thereby driving the two movable blocks 2102 to synchronously and reversely move, thereby making the two fourth gears 2104 respectively engaged with the teeth of the two straight racks 2103, thereby driving the pressing arms 19 to rotate along the hinging shafts, in the process of placing the tower drum, the two pressing arms 19 are away from each other, which does not affect the normal hoisting of the tower drum, when hoisted, the two pressing arms 19 are close to each other, thereby making the two pressing wheels 20 roll-press the tower drum.

According to the welding requirements of internal welding or external welding, the height of the lifting plate 2203 is adjusted through the multi-stage hydraulic rod 2204. When external welding, the translation plate 2201 is directly slid, so that the welding piece 12 is directly above the lap joint end of the two tower drums, 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 drum. When internal welding, the height of the lifting plate 2203 is adjusted, and the welding piece 12 and the cross rod 2205 are placed in the tower drum from one of the mounting drums 6, so that the internal girth welding can be performed.
