Description

Technical Field

[0001] The utility model relates to the technical field of wind power tower processing, in particular to a wind power tower welding auxiliary processing device. Background Art

[0002] A wind turbine tower is a tower for wind power generation, which mainly plays a supporting role in a wind turbine generator set. The height of a wind turbine tower is generally high. When in use, each single section needs to be welded and fixed before being transported to the installation site for installation and use. In the process of welding the wind turbine tower, due to its large size, auxiliary tools are required for auxiliary welding processing.

[0003] To address this issue, Chinese patent number CN116586890A proposes a wind turbine tower welding auxiliary processing device. By arranging support rods, frame rods, and sliding rods, the tower section can be directly slid horizontally outside the welding machine during welding. This eliminates the need to re-laser-position the welding machine along the length of the tower after each lifting of the section, which reduces operational accuracy and saves a certain amount of time.

[0004] However, the volume of the wind turbine tower is too large. During the butt welding process between single sections, although the above technical solution can realize the automatic rotation of the cylinder section, thereby facilitating the welding equipment to perform circular trajectory welding on the surface, when welding the next cylinder section after welding, in addition to rotating the cylinder section, the cylinder section also needs to be displaced to make it butt-jointed. Since the cylinder section is too heavy and supported by a rotating structure, it is very inconvenient to move. Using external equipment to forcefully push it to move and join may cause wear on the outer paint surface. If two sets of auxiliary tools with rotational supports are used, it cannot be guaranteed that the two sets of auxiliary devices maintain the same rotation speed when rotating the cylinder section, which is easy to cause dislocation during welding and affect the welding effect. In this regard, this design proposes an auxiliary processing device for wind turbine tower welding. Utility Model Content

[0027] The docking mechanism 2 includes a first slide 201 opened in the middle position of the top of the welding base 1, a connecting groove 202 is opened on one side of the outer wall of the welding base 1, and a plurality of support pads 203 are slidably provided on the inner wall of the first slide 201. Arc-shaped connecting frames 204 are fixed on both sides of the top of each support pad 203. A first roller 205 is rotatably provided on the top of each arc-shaped connecting frame 204. A second roller 206 is rotatably provided at the middle position of the top of each support pad 203. The inner wall of each second roller 206 passes through the inner walls of both ends of each support pad 203 and is connected to a connecting shaft 207. A card hole 208 is opened at one end of each connecting shaft 207, and a card hole 208 is opened at the other end of each connecting shaft 207. A first clamping shaft 209 is fixed at one end, and both sides of the top of each supporting pad 203 are rotatably connected to the first roller 205 through an arc-shaped connecting frame 204. An arc-shaped dislocation is formed between the first rollers 205 on both sides and the second roller 206 in the middle, which facilitates the contact and support of the cylinder section of the cylindrical wind turbine tower. When the second roller 206 actively rotates and rotates with the cylinder section, the first rollers 205 on both sides contact the outer wall and rotate together, making the rotation of the cylinder section smoother. The middle position of the outer wall of the connecting shaft 207 is fixedly connected to the inner wall of the second roller 206. When the first clamping shaft 209 rotates with the clamping hole 208, the connecting shaft 207 rotates with the second roller 206.

[0028] A U-shaped bracket 210 is fixed to one side of each support pad 203, and the outer wall of each U-shaped bracket 210 is respectively connected to the inner wall of the connecting groove 202, and a limiting piece 211 is threadedly connected to one side of each U-shaped bracket 210. A handle 212 is fixed to one end of each limiting piece 211. When the support pads 203 are pulled together tightly by the U-shaped bracket 210 and the cylinder section at the upper end is contacted and squeezed together, the handle 212 is rotated to make the limiting piece 211 penetrate the U-shaped bracket 210 and squeeze the outer wall of the welding base 1, thereby fixing the position of the support pad 203, so that the cylinder section will not move away during welding, causing the gap to be too large;

[0029] Furthermore, a first motor 3 is mounted on the upper edge of one side of the inner wall of the first chute 201. A second clamping shaft 4 is fixed to the output end of the first motor 3. The first clamping shaft 209 and the second clamping shaft 4 are both limited after being clamped into the clamping hole 208, so that when they rotate, they can rotate with the connecting shaft 207.

[0030] Furthermore, the welding mechanism 5 includes a movable bracket 501 mounted on one side of the welding base 1. An electric telescopic rod 502 is fixed to the top of the movable bracket 501. A support frame 503 is fixed to the output end of the electric telescopic rod 502. During welding, the electric telescopic rod 502 is extended and retracted to move the support frame 503 up and down, thereby facilitating contact with the cylinder section for welding.

[0031] Furthermore, a limiting groove 504 is provided on the top of the support frame 503 , and a gear 505 is rotatably provided at the bottom of the inner wall of the limiting groove 504 . One end of the gear 505 passes through the outer wall of one side of the support frame 503 and is connected to a second motor 506 .

[0032] The inner wall of the limiting groove 504 is interspersed with a connecting plate 507, and a rack 508 is fixed to the bottom of the connecting plate 507, and the outer wall of the rack 508 is meshed with the outer wall of the gear 505. An electric welding gun 509 is installed at one end of the connecting plate 507. When welding, the electric telescopic rod 502 is started to lower the support frame 503 and the electric welding gun 509 so that they contact the connecting area of ​​the cylinder segment and weld the connecting area evenly as the cylinder segment rotates. When the welded wind turbine tower needs to be removed later, the second motor 506 is started to rotate the gear 505 to mesh with the rack 508, and then the connecting plate 507 is driven to slide in the limiting groove 504, so that the connecting plate 507 and the electric welding gun 509 are moved to one side, so that they will not be blocked when dismantling the wind turbine tower.

[0033] Furthermore, a second slide groove 6 is provided on one side of the top of the welding base 1, and a third slide groove 7 is provided on the other side of the outer wall of the welding base 1, and the outer walls of the two ends of the movable bracket 501 are slidingly connected with the inner walls of the second slide groove 6 and the inner walls of the third slide groove 7 respectively. The inner wall of the third slide groove 7 is rotatably provided with a screw rod 8, and the outer wall of the screw rod 8 is threadedly connected to the inner wall of one side of the movable bracket 501. One end of the screw rod 8 passes through the outer wall of one side of the welding base 1 and is connected to a third motor 9. According to the actual length of a single cylinder section, the third motor 9 is started to rotate the screw rod 8 and then the threaded rotating movable bracket 501 drives the entire welding mechanism 5 to slide and adjust the position in the second slide groove 6 and the third slide groove 7, so that the welding gun 509 can always be welded in the connection area, thereby improving the welding quality and accuracy.

[0034] Working principle: When using the wind turbine tower welding auxiliary processing device in this design, it is first necessary to place the cylinder section of the single-section wind turbine tower on the top of the corresponding support pad 203, and then pull the two adjacent support pads 203 in the connecting groove 202 through the U-shaped bracket 210 so that it slides with the support pads 203 in the first slide groove 201 so that they are close together, and then the first clamping shaft 209 on one side of one of the support pads 203 is clamped into the clamping hole 208 on the side of the other support pad 203, and the support pad 203 on the side is moved to the edge of the first slide groove 201 and clamped with the clamping hole 208 on one side through the second clamping shaft 4. At this time, the cylinder sections above the two support pads 203 are docked together, and the first motor is started. While the second clamping shaft 4 is rotating, the second rollers 206 above the two supporting pads 203 are driven by the connecting shaft 207, the clamping hole 208 and the first clamping shaft 209 to rotate, and the two second rollers 206 rotate at the same speed, and they are in contact with the cylinder segments and drive the two cylinder segments to rotate in the same direction and at the same speed, and cooperate with the welding mechanism 5 above to perform welding. After welding is completed, the other supporting pads 203 are pushed in turn to fit tightly against the supporting pad 203 below the welded cylinder segment, so that the first clamping shaft 209 on them is locked with the clamping hole 208 on one side of the rear supporting pad 203 in turn, so as to realize the sequential docking of the cylinder segments, and all of them can rotate in the same direction and at the same speed, which not only facilitates the docking of the cylinder segments, but also ensures the welding quality between the cylinder segments and improves the auxiliary welding effect of the device.
