DETAILED DESCRIPTION

[0029] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0030] For example, see Figure 1-Figure 4 A welding device for a wind power tower comprises a welding table 1, on which a plurality of supporting members 101 are fixedly arranged, the supporting members 101 are used to support the tower to be welded, and a positioning sleeve 201 in a positioning assembly 2 is fixedly arranged at the center of the welding table 1, and a welding assembly 3 is also movably arranged inside the positioning sleeve 201, and a fourth movable slide groove 208 is provided at the inner wall of the positioning sleeve 201, and one end of a movable connecting rod 303 is slidably arranged inside the fourth movable slide groove 208, and the other end of the movable connecting rod 303 is slidably arranged inside a welding head 304, and the welding head 304 is rotatably arranged inside a limiting groove 306 through a corresponding rotating rod, and the limiting groove 306 is provided inside a moving block 301, and the moving block 301 is movably arranged inside the positioning sleeve 201; A connecting slot 308 is also provided inside the moving block 301 , and a knocking piece 305 is provided inside the connecting slot 308 through a rotating rod and a torsion spring for rotation. The knocking piece 305 is used to knock the tower tube that has been welded.

[0031] A connecting shaft 307 is provided on the moving block 301, and both ends of the connecting shaft 307 are fixedly sleeved with a first gear 302, each first gear 302 is meshed with the corresponding moving ring gear 207, the moving ring gear 207 is fixedly set on the inner wall of the positioning sleeve 201, and the moving ring gear 207 is symmetrically arranged on both sides of the fourth moving slide groove 208, and a first sliding block 311 is also provided inside the limiting groove 306, and a second sliding block 312 is slidably arranged inside the first sliding block 311.

[0032] A connecting plate 202 is also provided on one side of the positioning sleeve 201. The positioning sleeve 201 and the connecting plate 202 are connected by a plurality of fixed connecting rods. A first movable groove 204 is also provided on the surface of the positioning sleeve 201 on one side close to the connecting plate 202, and a movable slider 203 is slidably provided inside the first movable groove 204.

[0033] A second movable sliding groove 205 and a third movable sliding groove 206 are respectively formed on the inner walls of both sides of the positioning sleeve 201 .

[0034] In this embodiment: before the user welds the wind power tower, the tower to be welded needs to be transported to the corresponding supporting member 101. As the supporting member 101 supports the tower, the user only needs to use a pushing device commonly used by people in the field to transport the tower to the inside of the positioning sleeve 201. When the two towers are spliced, the user can start the external motor set on the moving slider 203. Since the output end of the external motor is fixedly connected to one end of the connecting shaft 307, the connecting shaft 307 will rotate accordingly as the external motor is started. On the one hand, since the corresponding first gear 302 is fixedly sleeved on the connecting shaft 307, and the first gear 302 and the corresponding moving ring gear 207 are meshed with each other, and the connecting shaft 307 is also provided with a moving block 301, when the connecting shaft 307 rotates, through the meshing between the first gear 302 and the corresponding moving ring gear 207, the moving block 301 will move accordingly in a circular trajectory inside the positioning sleeve 201. It should be noted that the two side surfaces of the moving block 301 are also provided with corresponding connecting slide bars 328, and the positioning sleeve 201 is also provided with a connecting slide groove 209 for the connecting slide bar 328 to slide in the shape of the corresponding slide bar, and this setting is to prevent the moving block 301 from shifting when moving, thereby affecting the subsequent welding effect, and since a welding head 304 is also provided inside the limiting groove 306, the welding head 304 can complete the welding effect of the spliced ​​tower tube with the movement of the moving block 301; On the other hand, since one end of the moving link 303 is slidably arranged inside the welding head 304, and a connecting spring is arranged between the moving link 303 and the welding head 304, and the other end of the moving link 303 is slidably arranged inside the fourth moving groove 208 through a corresponding ball bearing, when the moving block 301 moves, the moving link 303 will also slide accordingly inside the fourth moving groove 208.

[0035] Since the fourth moving slot 208 is in a wave shape, the sliding of the moving link 303 in the fourth moving slot 208 can make the moving link 303 swing left and right, and the welding head 304 is arranged in the limiting slot 306 by the corresponding rotation of the rotating rod. Therefore, when the moving link 303 swings left and right, the welding head 304 also swings left and right, and this swinging also allows the welding head 304 to complete the welding effect of the spliced ​​tower in a Z-shaped trajectory, and this Z-shaped trajectory welding method also makes the welding of the tower more compact, thereby improving the welding effect of the tower; It should be noted that the welding head 304 can be divided into a welding end and a positioning end, and a connecting spring is arranged between the welding end and the positioning end. This arrangement is to allow the welding head 304 to perform swing welding on the tower. Since the welding head 304 will swing in the left and right directions, when the welding end of the welding head 304 faces the welding point, the connecting spring can be used to adjust the length of the welding end of the welding head 304 adaptively, so as to better achieve the welding effect.

[0036] It should be noted that one end of the connecting shaft 307 is slidably set inside the second movable groove 205, and the other end of the connecting shaft 307 passes through the third movable groove 206 to form a fixed connection with the output end of the external motor. This connection method also makes the movement of the moving block 301 more stable, thereby making the welding of the welding head 304 more stable.

[0037] It should be noted that, due to the opening of the third movable slot 206, part of the positioning sleeve 201 is in a suspended state. Therefore, by setting the connecting plate 202 and the corresponding fixed connecting rod, the fixed connection effect of this part of the suspended positioning sleeve 201 can be effectively achieved.

[0038] Through the above-mentioned arrangement, not only the welding effect of the spliced ​​tower is effectively completed, but also through the arrangement of the fourth movable slide groove 208, the moving block 301 can be moved so that the welding head 304 arranged inside the moving block 301 can complete the welding effect in a left-right swinging manner, thereby making the welding effect tighter, thereby improving the overall welding effect of the spliced ​​tower.

[0039] Embodiment 2: This embodiment is an improvement made on the basis of Embodiment 1. Figure 1-Figure 10 As shown, the first sliding block 311 is slidably set inside the limiting groove 306, and the bottom surface of the first sliding block 311 is in contact with the connecting ring 321, and the connecting ring 321 is fixedly sleeved on the moving connecting rod 303, and the fourth gears 318 are rotatably set on the arc surfaces on both sides of the first sliding block 311, and each fourth gear 318 is meshed with the corresponding third rack 317, and the third rack 317 is fixedly set on the inner wall of the limiting groove 306.

[0040] Each fourth gear 318 is also meshed with a corresponding fourth rack 319 . The fourth rack 319 is fixedly disposed on the arc surface of the second sliding block 312 , and the second sliding block 312 is slidably disposed inside the first sliding block 311 . An accommodating cavity 316 is also provided inside the second sliding block 312 .

[0041] A plurality of elastic limiting plates 320 are fixedly arranged on the inner wall of the accommodating cavity 316 . A movable slide bar 315 is also slidably arranged inside the accommodating cavity 316 , and a limiting slide bar is also fixedly arranged on the movable slide bar 315 .

[0042] Both ends of the movable slide rod 315 are provided with extrusion slopes, and at least one end of the movable slide rod 315 is slidably set inside the corresponding fifth movable slide groove 322, and the fifth movable slide groove 322 is opened on the inner wall of the limiting groove 306, and a corresponding extrusion block 323 is also set inside the fifth movable slide groove 322.

[0043] The movable slide rod 315 is also fixedly connected to one end of the first connecting rod 324 and the second connecting rod 325 respectively, the other end of the first connecting rod 324 is fixedly connected to the positioning plate 326, and the second rack 314 is fixedly provided on the positioning plate 326, and the other end of the second connecting rod 325 is fixedly connected to the first rack 313, and the first rack 313 and the second rack 314 are respectively meshed with the corresponding second gear 309.

[0044] The two second gears 309 are arranged at the connection between the connecting slot 308 and the limiting slot 306, and the two second gears 309 are fixedly sleeved on the corresponding rotating rod, and the second gear 309 meshing with the first rack 313 is also meshed with the third gear 310, and the third gear 310 is fixedly sleeved on the rotating rod of the knocking member 305.

[0045] In this embodiment: on the one hand, since one end of the moving link 303 is slidably disposed inside the fourth moving slot 208, and the opening trajectory of the fourth moving slot 208 is a wave shape, the moving link 303 will swing leftward or rightward under the restriction of the fourth moving slot 208. It should be noted that the opening horizontal depth of the fourth moving slot 208 is the same; On the other hand, the other end of the movable link 303 is slidably set inside the welding head 304, so the welding head 304 will move synchronously with the movable link 303, and the welding head 304 is set inside the limiting groove 306 by rotating the corresponding rotating rod. Therefore, when the movable link 303 slides to the left or right inside the fourth movable slide groove 208, under the left and right swing of the welding head 304, the movement trajectory of the movable link 303 will be an arc trajectory, and the horizontal depth of the fourth movable slide groove 208 is the same. This arc trajectory movement will allow the movable link 303 to extend a distance outward from the inside of the welding head 304.

[0046] When the movable link 303 moves out of the welding head 304, since the movable link 303 is also fixedly sleeved with the connecting ring 321, and the top surface of the connecting ring 321 is in contact with the first sliding block 311, it should be noted that the first sliding block 311 is slidably arranged on the inner wall of the limiting groove 306 by the third sliding block 327, and a corresponding spring is also arranged between the third sliding block 327 and the sliding groove opened by the limiting groove 306. This arrangement is to allow the first sliding block 311 squeezed by the movable link 303 to be quickly reset when the movable link 303 is reset, so that the subsequent movable link 303 can still drive the first sliding block 311 to move accordingly, which makes the first sliding block 311 move synchronously with the movable link 303 after the movable link 303 moves; Since fourth gears 318 are rotatably arranged at both ends of the first sliding block 311, on the one hand, the fourth gear 318 is meshed with the third rack 317 arranged on the inner wall of the accommodating chamber 316, and on the other hand, the fourth gear 318 is also meshed with the fourth rack 319 arranged on the surface of the second sliding block 312. Therefore, when the first sliding block 311 moves, it can not only drive the second sliding block 312 arranged inside the first sliding block 311 to move accordingly, but also when the first sliding block 311 moves, the fourth gear 318 is driven to rotate through the meshing between the fourth gear 318 and the third rack 317, thereby driving the same Similarly, the second sliding block 312 meshing with the fourth gear 318 through the fourth rack 319 performs a corresponding movement, and this movement is based on the movement of the first sliding block 311. Therefore, the first sliding block 311 only needs to move a small distance, and the second sliding block 312 can move a larger distance. The movement of the second sliding block 312 also completes the meshing effect between the first rack 313 and the second rack 314 connected to the second sliding block 312 and the corresponding second gear 309, thereby driving the knocking piece 305 to complete the corresponding rotation effect, so that the knocking piece 305 can smoothly perform the knocking effect on the welding point.

[0047] Since a movable slide bar 315 is slidably arranged inside the second sliding block 312, on the one hand, the movable slide bar 315 is slidably arranged inside the groove body opened at the bottom of the accommodating chamber 316 through the corresponding slide bar, and a limit rod is fixedly arranged on the movable slide bar 315, and a plurality of elastic limit plates 320 are arranged at the inner wall of the accommodating chamber 316 at the position corresponding to the limit rod, and at the same time, corresponding extrusion inclined surfaces are opened at both ends of the movable slide bar 315, and at least one end of the movable slide bar 315 is slidably arranged inside the corresponding fifth movable slide groove 322, so that when the second sliding block 312 moves, one end of the movable slide bar 315 will be in the corresponding fifth movable slide groove 322. The movable slide bar 315 slides inside the fifth movable slide groove 322, and since each fifth movable slide groove 322 is provided with a corresponding extrusion block 323, when the second sliding block 312 moves, the movable slide bar 315 will be squeezed by the corresponding extrusion block 323, so that the movable slide bar 315 can perform a corresponding movement effect inside the second sliding block 312, and due to the setting of the limit rod and the elastic limit plate 320, the movable slide bar 315 can be stably located inside the second sliding block 312 after stopping moving, so that the subsequent second rack 314 or the first rack 313 can smoothly mesh with the corresponding second gear 309; On the other hand, the movable slide rod 315 is respectively connected to one end of the first connecting rod 324 and the second connecting rod 325, and the other end of the first connecting rod 324 is fixedly connected to the positioning plate 326, and the second rack 314 is staggered on the positioning plate 326, and the tooth mouth of the second rack 314 is opened in the direction of the second sliding block 312, and the other end of the second connecting rod 325 is fixedly connected to the first rack 313, and the first rack 313 is meshed and connected with the corresponding second gear 309, and the second gear 309 is meshed with the third gear 310, and the third gear 310 is fixedly sleeved on the rotating rod connected to the knocking member 305. Therefore, when the second sliding block 312 moves, the movable slide rod 315 squeezed by the squeezing block 323 will drive the first connecting rod 324 and the second connecting rod 325 to follow the second sliding block 312 to perform a corresponding movement effect.

[0048] Since the first rack 313 is meshed with the corresponding second gear 309 in the initial state, when the second sliding block 312 moves, the first rack 313 will drive the second gear 309 to rotate accordingly, and then drive the third gear 310 to rotate in the opposite direction, so that the knocking piece 305 can complete a certain rotation effect. As the second sliding block 312 continues to move, the first rack 313 will eventually separate from the corresponding second gear 309. At the moment when the second gear 309 is disengaged from the first rack 313, the third gear 310, the second gear 309 and the knocking piece 305 will all perform corresponding reset rotations through the reset force of the torsion spring, and the knocking piece 305 will rotate a short distance more due to the influence of inertia, and this short distance allows the knocking piece 305 to complete the corresponding knocking effect on the welding point that has been completed, thereby realizing the knocking removal of welding slag.

[0049] When the second sliding block 312 continues to move, the moving slide rod 315 will eventually contact the extrusion block 323 inside the corresponding fifth moving slide groove 322, and under the extrusion action of the extrusion block 323, a corresponding movement effect is performed. On the one hand, this movement causes the position of the first rack 313 and the corresponding second gear 309 to be misaligned, so that when the second sliding block 312 is reset, there will be no meshing effect between the first rack 313 and the second gear 309, so as to prevent the meshing between the two from affecting the subsequent knocking of the welding point by the knocking piece 305.

[0050] On the other hand, when the movable slide bar 315 moves, the second rack 314 will also move synchronously with the movable slide bar 315, and the reset trajectory of the second rack 314 will make the second rack 314 and the corresponding second gear 309 mesh with each other, and because the second gears 309 are connected by corresponding rotating rods, when the second sliding block 312 is reset and moves downward, the second gear 309 meshing with the second rack 314 rotates, and the second gear 309 meshing with the third gear 310 also rotates The second rack 314 and the second gear 309 are moved upwards to move the second sliding block 312 downwards, thereby causing the knocking piece 305 to rotate accordingly. When the second rack 314 moving downwards is separated from the corresponding second gear 309, the knocking piece 305 will reset and rotate to knock. As the second sliding block 312 continues to move downwards, the moving slide bar 315 will eventually come into contact with the inside of the fifth moving slide groove 322 and the extrusion block 323 on the other side, causing the second rack 314 to be offset from the second gear 309, thereby facilitating the subsequent upward movement of the second sliding block 312, thereby achieving a corresponding knocking effect on the welded welding point.

[0051] It should be noted that both the first sliding block 311 and the second sliding block 312 are provided with through slots for the movable connecting rod 303 to swing left and right, and this arrangement also allows the movable connecting rod 303 to swing smoothly to avoid being stuck; Through the above-mentioned arrangement, not only can the movable connecting rod 303 complete the reciprocating movement inside the welding head 304 during the sliding process inside the fourth movable slide groove 208, but also this reciprocating movement allows the first rack 313 and the second rack 314 connected to the second sliding block 312 to perform a synchronous reciprocating movement effect inside the limiting groove 306, and the movement of the first rack 313 and the second rack 314 will also drive the corresponding second gear 309 to rotate, and then drive the knocking member 305 to complete the corresponding rotation effect, so that when the knocking member 305 is reset, it can effectively perform the corresponding knocking effect on the welding point that has been completed, and this knocking also makes the welding point after welding tighter, so as to effectively improve the welding effect of the tower.

[0052] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.

[0053] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
