Description

Technical Field

[0001] The present invention relates to the technical field of welding equipment, and in particular to fully automatic welding equipment for high-strength steel towers. Background Art

[0002] In the fields of wind power generation, chemical equipment and large-scale building structures, high-strength steel towers are key supporting structural components, and their quality is directly related to the safety of equipment operation and service life. The welding process is the core link in the manufacture of high-strength steel towers. The welding quality and efficiency have a decisive impact on the performance and production benefits of the towers. With the rapid development of related industries, the demand for high-strength steel towers is increasing, and higher requirements are also placed on their welding quality and production efficiency.

[0003] At present, the common high-strength steel tower welding equipment on the market has significant defects in actual application. Most of the existing welding equipment only has basic welding functions and lacks automatic shifting mechanisms. After completing the welding of a section of the tower, manual operation of a crane or other handling equipment is required to move the welded tower from the welding station and then place the next section of the tower to be welded to the welding station. This process not only consumes a lot of manpower and time, but also manual handling has operational errors and safety risks, which can easily cause bumps and damage to the tower surface and affect the quality of the tower. At the same time, due to the low efficiency of manual handling, the welding equipment is in an idle waiting state for a long time, which seriously reduces the utilization rate of the equipment and makes it impossible to carry out welding work continuously, which greatly affects the production progress of high-strength steel towers. Therefore, improvement is urgently needed. Summary of the Invention

[0066] After the distance between the two supporting parts is adjusted, the two towers to be welded are placed on the two supporting mechanisms respectively, and then the axes of the two towers to be welded are adjusted until the axes of the two towers to be welded coincide. The specific process is as follows: the control device 2 controls the electric push rod 10 to start, so that the electric push rod 10 pushes the supporting platform 13 to move, and then the tower supported by the supporting part on the supporting platform 13 moves until the axes of the towers on the two supporting mechanisms coincide;

[0067] This device is provided with an alignment part, which enables the device to align the axes of the two towers placed on the two supporting mechanisms until the axes of the two towers to be welded coincide, thereby facilitating the subsequent welding of the towers by the device and improving the welding quality of the towers after welding to a certain extent.

[0068] The support mechanism also includes a bearing platform 13 slidably arranged on the fixed block 8, and the surface of the bearing platform 13 close to the return spring 12 is in contact with the return spring 12.

The first double-headed screw 23 cooperates with the threaded transmission between the two sliding carriers 17, thereby making the two sliding carriers 17 on the same carrier 13 move closer to or away from each other, until the support wheel 20 rotatably connected to the upper plate 18 of the sliding carrier 17 can lift the tower to be welded;

[0070] The device is provided with an adjustment part, so that the device can adjust the distance between the two support parts on the same supporting platform 13 according to the size of the tower to be welded, so that the device can be adapted to the support requirements of towers to be welded of different sizes.

[0077] A swing block 28 is fixedly mounted on the swing shaft 26;

[0078] The welding part is provided on the swing block 28 and is electrically connected to the control device 2. The welding part is used to weld the tower to be welded. The welding part includes:

[0079] An electric telescopic shaft 29 is provided on the swing block 28 and is electrically connected to the control device 2;

[0082] A fine-tuning shaft 32 is rotatably mounted on the C-shaped plate 30 , and one end of the fine-tuning shaft 32 close to the fine-tuning motor 31 is fixedly connected to the output end of the fine-tuning motor 31 ;

[0083] The welding gun 33 is fixedly mounted on the fine-tuning shaft 32 and electrically connected to the control device 2 . The welding gun 33 is used for welding the tower.

[0084] After the axes of the two towers to be welded are aligned and overlapped, the control device 2 controls the electric telescopic shaft 29 to start, so that the C-shaped plate 30 provided on the electric telescopic shaft 29 drives the fine-tuning shaft 32 to move toward the splicing of the two towers, and then the welding gun 33 rotatably connected to the fine-tuning shaft 32 moves toward the splicing of the two towers, until the distance between the welding gun 33 and the splicing of the two towers reaches a preset value (pre-set by experienced personnel), and then the control device 2 controls each first motor 21 to start, so that each fixed shaft 19 fixedly connected to the output end of each first motor 21 rotates, thereby rotating the support wheel 20 provided on the fixed shaft 19, so that the towers to be welded placed on the support wheels 20 on both sides of the shift mechanism rotate synchronously, and then the control device 2 controls the welding gun 33 to start, and the welding gun 33 starts to weld the splicing of the two towers until the welding gun 33 completes the welding of the two towers;

[0085] It should be noted that when the welding gun 33 is welding the joint of the two towers, the swing motor 27 is started by the control device 2, so that the swing shaft 26 fixedly connected to the output end of the swing motor 27 rotates, and then the swing block 28 fixedly connected to the swing shaft 26 reciprocates around the axis of the swing shaft 26 at a certain angle, so that the electric telescopic shaft 29 provided on the swing block 28 reciprocates around the axis of the swing shaft 26 at a certain angle, and then drives the C-shaped plate 30 fixedly connected to the electric telescopic shaft 29 to reciprocate around the axis of the swing shaft 26 at a certain angle, so that the fine-tuning shaft 32 rotatably connected to the C-shaped plate 30 reciprocates around the axis of the swing shaft 26 at a certain angle. The reciprocating rotation of the angle drives the welding gun 33 fixedly connected to the fine-tuning shaft 32 to reciprocate at a certain angle around the axis of the swing shaft 26, so that the device can increase the welding width to a certain extent, thereby improving the welding quality of the device to a certain extent; at the same time, when the welding gun 33 rotates away from the bottom of the swing shaft 26, the control device 2 controls the fine-tuning motor 31 to start, so that the welding gun 33 fixedly connected to the output end of the fine-tuning motor 31 rotates at a certain angle around the fine-tuning shaft 32, so that the welding gun 33 can always be aligned with the part to be welded when it reciprocates at a certain angle around the axis of the swing shaft 26, thereby further improving the welding quality of the tower by the device;

The screw 23 rotates, and the two sliding platforms 17 are synchronized to move away from the tower through the threaded transmission between the first double-headed screw 23 and the two sliding platforms 17, until the support wheel 20 above the sliding platform 17 is out of contact with the tower. Then, the control device 2 controls the shift motor 39 to start, thereby rotating the shift roller 38 fixedly connected to the output end of the shift motor 39, so that the welded tower slides along the axis of the pitch-adjusting screw 25 until one end of the welded tower is directly below the welding gun 33, thereby continuously welding the subsequent towers.

[0096] The device is provided with a shifting mechanism, so that the device can automatically move the welded tower, thereby facilitating the subsequent continuous welding work on the tower, thereby improving the welding efficiency of the device to a certain extent.

[0097] Working principle: During operation, the distance between the two supporting parts on the same carrier 13 is adjusted according to the size of the tower to be welded. The specific process is as follows: the first adjusting motor 22 is controlled by the control device 2 to start, thereby rotating the first double-headed screw 23 fixedly connected to the output end of the first adjusting motor 22. The first double-headed screw 23 cooperates with the threaded transmission between the two sliding carriers 17, thereby making the two sliding carriers 17 on the same carrier 13 move closer to or away from each other, until the support wheel 20 rotatably connected to the upper plate 18 of the sliding carrier 17 can lift the tower to be welded;

[0098] After the distance between the two supporting parts is adjusted, the two towers to be welded are placed on the two supporting mechanisms respectively, and then the axes of the two towers to be welded are adjusted until the axes of the two towers to be welded coincide. The specific process is as follows: the control device 2 controls the electric push rod 10 to start, so that the electric push rod 10 pushes the supporting platform 13 to move, and then the tower supported by the supporting part on the supporting platform 13 moves until the axes of the towers on the two supporting mechanisms coincide;

[0099] After the axes of the two towers to be welded are aligned and overlapped, the control device 2 controls the electric telescopic shaft 29 to start, so that the C-shaped plate 30 provided on the electric telescopic shaft 29 drives the fine-tuning shaft 32 to move toward the splicing of the two towers, and then the welding gun 33 rotatably connected to the fine-tuning shaft 32 moves toward the splicing of the two towers, until the distance between the welding gun 33 and the splicing of the two towers reaches a preset value (pre-set by experienced personnel), and then the control device 2 controls each first motor 21 to start, so that each fixed shaft 19 fixedly connected to the output end of each first motor 21 rotates, thereby rotating the support wheel 20 provided on the fixed shaft 19, so that the towers to be welded placed on the support wheels 20 on both sides of the shift mechanism rotate synchronously, and then the control device 2 controls the welding gun 33 to start, and the welding gun 33 starts to weld the splicing of the two towers until the welding gun 33 completes the welding of the two towers;

[0100] It should be noted that when the welding gun 33 is welding the joint of the two towers, the swing motor 27 is started by the control device 2, so that the swing shaft 26 fixedly connected to the output end of the swing motor 27 rotates, and then the swing block 28 fixedly connected to the swing shaft 26 reciprocates around the axis of the swing shaft 26 at a certain angle, so that the electric telescopic shaft 29 provided on the swing block 28 reciprocates around the axis of the swing shaft 26 at a certain angle, and then drives the C-shaped plate 30 fixedly connected to the electric telescopic shaft 29 to reciprocate around the axis of the swing shaft 26 at a certain angle, so that the fine-tuning shaft 32 rotatably connected to the C-shaped plate 30 reciprocates around the axis of the swing shaft 26 at a certain angle. The reciprocating rotation of the angle drives the welding gun 33 fixedly connected to the fine-tuning shaft 32 to reciprocate at a certain angle around the axis of the swing shaft 26, so that the device can increase the welding width to a certain extent, thereby improving the welding quality of the device to a certain extent; at the same time, when the welding gun 33 rotates away from the bottom of the swing shaft 26, the control device 2 controls the fine-tuning motor 31 to start, so that the welding gun 33 fixedly connected to the output end of the fine-tuning motor 31 rotates at a certain angle around the fine-tuning shaft 32, so that the welding gun 33 can always be aligned with the part to be welded when it reciprocates at a certain angle around the axis of the swing shaft 26, thereby further improving the welding quality of the tower by the device;

[0101] After the tower is welded by the device, the second regulating motor 40 is started by the control device 2, so that the second double-headed screw 41 fixedly connected to the output end of the second regulating motor 40 rotates, and the second double-headed screw 41 cooperates with the threaded transmission between the two shifting platforms 36, so that the two shifting platforms 36 move synchronously toward the direction of the tower until the shift roller 38 above the shifting platform 36 is in contact with the surface of the tower, and then the control device 2 is used to control each first regulating motor 22 to start, so that the first double-headed screw 41 fixedly connected to the output end of the first regulating motor 22 rotates. The screw 23 rotates, and through the threaded transmission between the first double-headed screw 23 and the two sliding platforms 17, the two sliding platforms 17 move synchronously in the direction away from the tower until the support wheel 20 above the sliding platform 17 is out of contact with the tower, and then the control device 2 controls the shift motor 39 to start, so that the shift roller 38 fixedly connected to the output end of the shift motor 39 rotates, so that the welded tower slides along the direction of the axis of the pitch adjustment screw 25 until one end of the welded tower is located directly below the welding gun 33, thereby achieving continuous welding of the subsequent tower.
