[0015] A wind power tower welding method, using the wind power tower welding device described above, comprises the following steps:

[0016] S1: When the tower needs to be welded, the first motor is started. The rotation of the first motor drives the rotation of the rotating rod and the rotating plate, so that the push rod slides in the slide groove and pushes the support block and the first ball to move downward. At the same time, the first spring is compressed. At this time, the downward tilt angle of the rotating plate can be determined by observing the angle mark indicated by the pointer, and it can be ensured that it is the same as the taper of the tower. Then, the tower is placed on the first ball for support, which can ensure that it is in a horizontal state, so that the two sections of the tower can be aligned, so as to facilitate adjustment according to the taper of the tower, so that the support positioning of the tower is more convenient and the effect is better, thereby ensuring the efficiency and quality of subsequent welding;

[0017] S2: After the tower is positioned, the second moving assembly drives the second slider to move toward the first support plate. When the inclined surface abuts against the end of one of the tower sections, the moving block is pushed to move downward. At the same time, the second spring is compressed, so that the visual sensor moves to the bottom of the tower. Then, the first moving assembly drives the first slider to move toward the first support plate, thereby driving the second support plate and the second disc to move synchronously, thereby pushing the tower to move, and clamping the tower between the first disc and the second disc, and the two ends of the tower abut against the second ball and the third ball, so that the tower can be clamped and fixed;

[0018] S3: The second slider is moved again by the second moving assembly, so as to adjust the position of the moving block, so that the visual sensor is aligned with the welding point of the two tower sections, and when the second support plate moves, the moving plate is driven to move by the reset mechanism, thereby driving the mounting plate and the irradiation lamp to move, and when the moving plate moves, the sliding plate and the connecting rod are driven to move, and when the connecting rod is against the limit plate, the moving plate no longer moves, and at the same time, the fourth spring is gradually compressed, so as to ensure that the irradiation lamp is aligned with the visual sensor;

[0019] S4: Turn on the irradiation lamp and start the second motor at the same time. The rotation of the second motor drives the rotation of the roller, and then drives the two tower sections to rotate. Therefore, the visual sensor can detect whether there are defects in the welding position to ensure the quality of subsequent welding;

[0020] S5: After the inspection is completed, the moving block is moved to one side and away from the welding position by the second moving assembly, and then the tower is driven to continue to rotate by the driving mechanism, and the first welding robot and the second welding robot are used to perform double-sided welding on the tower respectively;

[0021] S6: After the welding is completed, the first slider is moved by the first moving assembly, and the second slider is moved by the second moving assembly, that is, the positions of the second disc and the moving block are adjusted to facilitate subsequent welding.

[0022] Compared with the prior art, the present invention has the following beneficial effects:

[0023] (1) This wind turbine tower welding device and method, by setting a pushing mechanism, etc., when the tower needs to be welded, the first motor is started, and the rotation of the first motor drives the rotation of the rotating rod, thereby driving the rotating plate to rotate downward, so that the pushing rod slides in the slide groove and pushes the support block and the first ball to move downward. At the same time, the first spring is compressed. At this time, the downward tilt angle of the rotating plate can be determined by observing the angle mark indicated by the pointer, and it can be ensured that it is the same as the taper of the tower. Then, the tower is placed on the first ball for support, which can ensure that it is in a horizontal state, which is convenient for the two sections of the tower to be aligned, so as to facilitate adjustment according to the taper of the tower, making the support positioning of the tower more convenient and more effective, thereby ensuring the efficiency and quality of subsequent welding.

[0024] (2) This wind power tower welding device and method, by setting up a detection mechanism, etc., after the tower is positioned, the second moving component drives the second slider to move in the direction close to the first support plate. When the inclined surface abuts against the end of one of the tower sections, the moving block is pushed to move downward. At the same time, the second spring is compressed, so that the visual sensor moves to the bottom of the tower. Then, the first moving component drives the first slider to move in the direction close to the first support plate, thereby driving the second support plate and the second disc to move synchronously, thereby pushing the tower to move, and clamping the tower between the first disc and the second disc, and the two ends of the tower abut against the second ball and the third ball, so that the tower can be clamped and fixed. Then, the first moving component is used again to move the first slider in the direction close to the first support plate, thereby driving the second support plate and the second disc to move synchronously, thereby pushing the tower to move, and clamping the tower between the first disc and the second disc, and the two ends of the tower abut against the second ball and the third ball, so that the tower can be clamped and fixed. The second moving assembly moves the second slider, thereby adjusting the position of the moving block so that the visual sensor is aligned with the welding point of the two tower sections, and when the second support plate moves, the moving plate is driven to move by the resetting mechanism, thereby driving the mounting plate and the irradiation lamp to move. When the moving plate moves, it drives the sliding plate and the connecting rod to move. When the connecting rod and the limit plate are against each other, the moving plate no longer moves. At the same time, the fourth spring is gradually compressed, thereby ensuring that the irradiation lamp is aligned with the visual sensor. Finally, the irradiation lamp is turned on, and at the same time, the second motor is started. The rotation of the second motor drives the rotation of the roller, thereby driving the two tower sections to rotate. Therefore, the visual sensor can be used to detect whether there are defects in the welding point, thereby ensuring the quality of subsequent welding. BRIEF DESCRIPTION OF THE DRAWINGS

[0045] A wind power tower welding method, using the above-mentioned wind power tower welding device, comprises the following steps:

[0046] S1: When the tower needs to be welded, the first motor 402 is started. The rotation of the first motor 402 drives the rotation of the rotating rod 401 and the rotating plate 302, so that the push rod 304 slides in the slide groove 303, and pushes the support block 10 and the first ball 11 to move downward.

Then, the tower is placed on the first ball 11 for support, which can ensure that it is in a horizontal state, so that the two sections of the tower can be aligned, so as to facilitate adjustment according to the taper of the tower, so that the support positioning of the tower is more convenient and the effect is better, thereby ensuring the efficiency and quality of subsequent welding;

[0047] S2: After the tower is positioned, the second moving assembly 27 drives the second slider 25 to move toward the first support plate 12. When the inclined surface 502 abuts against the end of one section of the tower, the moving block 501 is pushed to move downward. At the same time, the second spring 603 is compressed, so that the visual sensor 503 moves to the bottom of the tower. Then, the first moving assembly 26 drives the first slider 16 to move toward the first support plate 12, thereby driving the second support plate 17 and the second disc 18 to move synchronously, thereby pushing the tower to move, and clamping the tower between the first disc 13 and the second disc 18, and the two ends of the tower abut against the second ball 14 and the third ball 19, so that the tower can be clamped and fixed;

[0048] S3: The second slider 25 is moved again by the second moving assembly 27, so as to adjust the position of the moving block 501, so that the visual sensor 503 is aligned with the welding point of the two tower sections, and when the second support plate 17 moves, the moving plate 22 is driven to move by the reset mechanism 8, and then the mounting plate 23 and the irradiation lamp 504 are driven to move. When the moving plate 22 moves, the sliding plate 802 and the connecting rod 901 are driven to move. When the connecting rod 901 abuts against the limiting plate 902, the moving plate 22 no longer moves. At the same time, the fourth spring 803 is gradually compressed, so as to ensure that the irradiation lamp 504 is aligned with the visual sensor 503.

[0049] S4: Turn on the irradiation lamp 504, and at the same time, start the second motor 703. The rotation of the second motor 703 drives the rotation of the roller 704, and then drives the two tower sections to rotate, so that the visual sensor 503 can detect whether there are defects in the welding position, thereby ensuring the quality of subsequent welding;

[0050] S5: After the inspection is completed, the moving block 501 is moved to one side and away from the welding position by the second moving assembly 27, and then the tower is driven to continue to rotate by the driving mechanism 7, and the first welding robot 21 and the second welding robot 24 are used to perform double-sided welding on the tower respectively;

[0051] S6: After the welding is completed, the first moving assembly 26 moves the first slider 16, and the second moving assembly 27 moves the second slider 25, that is, the positions of the second disc 18 and the moving block 501 are adjusted to facilitate subsequent welding.

A method for welding a wind turbine tower, using a wind turbine tower welding device as claimed in any one of claims 1 to 8, characterized in that: The following steps are involved: S1: When the tower needs to be welded, the first motor (402) is started. The rotation of the first motor (402) drives the rotation of the rotating rod (401) and the rotating plate (302), so that the push rod (304) slides in the slide groove (303) and pushes the support block (10) and the first ball (11) to move downward. At the same time, the first spring (203) is compressed. At this time, the downward tilt angle of the rotating plate (302) can be determined by observing the angle mark (2803) indicated by the pointer (2801), and it can be ensured that it is the same as the taper of the tower. Then, the tower is placed on the first ball (11) for support, which can ensure that it is in a horizontal state, so that the two sections of the tower can be aligned, so as to facilitate adjustment according to the taper of the tower, so that the support positioning of the tower is more convenient and the effect is better, thereby ensuring the efficiency and quality of subsequent welding; S2: After the tower is positioned, the second moving assembly (27) drives the second slider (25) to move toward the first support plate (12). When the inclined surface (502) abuts against the end of one of the tower sections, the moving block (501) is pushed to move downward. At the same time, the second spring (603) is compressed, so that the visual sensor (503) moves to the bottom of the tower. Then, the first moving assembly (26) drives the first slider (16) to move toward the first support plate (12), thereby driving the second support plate (17) and the second disc (18) to move synchronously, thereby driving the tower to move and clamping the tower between the first disc (13) and the second disc (18), and the two ends of the tower abut against the second ball (14) and the third ball (19), so that the tower can be clamped and fixed. S3: The second sliding block (25) is moved again by the second moving assembly (27), thereby adjusting the position of the moving block (501), so that the visual sensor (503) is aligned with the welding point of the two tower sections, and when the second support plate (17) is moved, the moving plate (22) is driven to move by the reset mechanism (8), thereby driving the mounting plate (23) and the irradiation lamp (504) to move. When the moving plate (22) moves, the sliding plate (802) and the connecting rod (901) are driven to move. When the connecting rod (901) and the limiting plate (902) are in contact, the moving plate (22) no longer moves. At the same time, the fourth spring (803) is gradually compressed, thereby ensuring that the irradiation lamp (504) and the visual sensor (503) are aligned. S4: Turn on the irradiation lamp (504), and at the same time, start the second motor (703), the rotation of the second motor (703) drives the roller (704) to rotate, and then drives the two tower sections to rotate, so that the visual sensor (503) can detect whether there are defects in the welding position, thereby ensuring the quality of subsequent welding; S5: After the inspection is completed, the moving block (501) is moved to one side and away from the welding position by the second moving assembly (27), and then the tower is driven to continue rotating by the driving mechanism (7), and the first welding robot (21) and the second welding robot (24) are used to perform double-sided welding on the tower respectively; S6: After the welding is completed, the first moving component (26) is used to move the first slider (16), and the second moving component (27) is used to move the second slider (25), that is, the positions of the second disc (18) and the moving block (501) are adjusted to facilitate subsequent welding.
