Description

Technical Field

[0001] The present invention relates to the technical field of steel structure welding, and specifically to a steel structure welding device for industrial plant construction. Background Art

[0002] The main load-bearing components of the plant are made of steel, including steel columns, steel beams, steel structure foundations, steel roof trusses and steel roofs. Due to the increase in China's steel production, most plants are steel structure plants, which can be further divided into light and heavy steel structure plants. A steel structure is a building structure composed of components such as steel beams, steel columns, and steel trusses made of steel sections and steel plates. Therefore, it is particularly suitable for building large-span, ultra-high, and ultra-heavy buildings. However, when welding equipment is used, the contact surfaces of the two steel materials to be welded are inclined, resulting in insecure welding of the steel materials during welding, reducing the welding effect of the equipment on the steel materials, making the steel materials prone to dislocation when placed on the equipment, and causing uneven stress during the welding of the steel materials. It is not easy to adjust the welding angle and position during the welding process of the steel materials, making it easy to have missed welding during the welding of the steel materials by the equipment, resulting in easy fracture at the welding position during the subsequent use of the steel materials, and it is not easy to control the placement position when the steel materials are placed.

[0003] Publication No. CN118371909B discloses a steel structure welding device for industrial plant construction, which is provided with a support plate, an adjustment arm, and a welding torch. By arranging two support plates on the base, it is convenient to keep the adjustment assembly horizontally installed on the support plate. The adjustment arm moves driven by a driver, so that the adjustment arm moves to adjust the position of the welding torch, facilitating the welding work of the welding torch at different positions of the steel materials driven by the adjustment arm. The clamping assembly is on the installation table and is at the same horizontal plane as the position where the adjustment assembly places the steel materials, facilitating the situation where the two steel materials are not prone to dislocation when they come into contact, preventing voids from occurring during the clamping of the steel materials and affecting the welding effect of the welding torch. However, the following problems still exist in the actual use of this patent:

[0004] Although the steel structure welding device for industrial plant construction can achieve the welding of steel materials, when welding a steel structure plant, since most steel structure plants are large-span, ultra-high, and ultra-heavy buildings, the steel structure steel materials used are long and heavy. This steel structure welding device for industrial plant construction cannot weld steel materials with large spans and heights and cannot adapt to the welding of steel structure plants.

[0005] Therefore, a steel structure welding device for industrial plant construction is proposed to solve the problems mentioned above. Summary of the Invention

By climbing, it can adapt to the welding of steel structure factories with large spans and heights. The specific content is as follows:

[0022] 1. By setting the positioning welding machine mechanism, not only can the inclined motor drive the first sprocket transmission assembly and the inclined threaded rod to rotate, enabling the inclined threaded sleeve to move up and down on the outer side of the inclined threaded rod while driving the inclined rotating rod to rotate, and under the action of the first connecting hinge, the rotation of the support bracket can be realized. At the same time, by utilizing the characteristic of the sliding connection between the clamping sliding rod and the clamping sliding sleeve inside the support bracket, when supporting the steel structure cross beam, the steel structure cross beam can extrude the clamping support tray, drive the clamping support rod and the clamping lifting plate to descend. Under the action of the clamping rotating rod, the clamping sliding sleeve drives the clamping sliding bracket to move relatively. Through the support spring and the clamping inclined plate, the steel structure cross beam is initially clamped and limited. The second connecting hinge and the clamping support plate on one side of the clamping top plate are used to limit the steel structure cross beam. At the same time, by utilizing the elastic force of the compression spring inside the pressing bracket, the rotating support of the clamping support plate can be realized, and the two sides of the steel structure cross beam can be clamped and limited, improving the clamping stability of the steel structure cross beam. By driving the longitudinal bidirectional threaded rod to rotate through the longitudinal motor, the two longitudinal threaded sleeves drive the longitudinal brackets to move relatively, and the longitudinal positions of the two welding devices can be adjusted. At the same time, starting the transverse motor to drive the transverse threaded rod to rotate, the transverse threaded sleeve drives the welding bracket to move horizontally, and starting the adjustment motor to drive the welding device to rotate, the splicing and welding of the steel structure column and the steel structure cross beam can be carried out, improving the welding accuracy. By adjusting the angle of the support bracket, it can adapt to steel structures at different angles, facilitating the steel structure welding of industrial buildings;

[0023] 2. By setting up the climbing mechanism, not only can the climbing motor drive the second sprocket transmission component and the climbing threaded rod to rotate, enabling the climbing threaded sleeve to drive the climbing support plate to move up and down, but also when the clamping motor is started to drive the clamping bidirectional threaded rod to rotate, the two clamping threaded sleeves drive the clamping limit plate and the clamping arms to move relative to each other, enabling the clamping and fixing of the steel structure column. When the clamping arm on one side of the first clamping bracket clamps and fixes the steel structure column, the clamping arm on one side of the second clamping bracket releases; when the clamping arm on one side of the first clamping bracket releases, the clamping arm on one side of the second clamping bracket clamps and fixes the steel structure column. Thus, the climbing function of the installation bracket can be realized, facilitating the movement of the installation bracket to the top of the steel structure column and cooperating with the tower crane for the positioning welding of the steel structure beam. There is no need for manual climbing to the top of the steel structure column, improving the safety and convenience of operation. By driving the rotating worm to rotate through the rotating motor and utilizing the meshing connection between the rotating worm and the rotating worm wheel, the rotation of the rotating plate can be realized, thereby adjusting the angle of the clamping arm on one side of the first clamping bracket and facilitating the welding of steel structures at different angles. The climbing method can adapt to the welding of steel structure workshops with large spans and heights. Description of the Drawings

A climbing mechanism 2 is arranged on one side of the positioning welding machine mechanism 1, and a second clamping bracket 213 is arranged on the outer side of the climbing mechanism 2. The positioning welding machine mechanism 1 includes an installation bracket 101. On one side of the bottom of the installation bracket 101, support blocks 102 are symmetrically installed. A first motor cover 103 is fixedly installed at the bottom of the installation bracket 101. Among them, an inclined motor 104 is fixedly installed on one side inside the first motor cover 103. The output end of the inclined motor 104 is fixedly connected to a first sprocket transmission assembly 105. Among them, on one side of the first sprocket transmission assembly 105, inclined threaded rods 106 are symmetrically connected. On the outer sides of the two inclined threaded rods 106, inclined threaded sleeves 107 are threadedly connected. On the tops of the two inclined threaded sleeves 107, inclined rotating rods 108 are rotatably connected. On the tops of the two inclined rotating rods 108, a support bracket 109 is rotatably connected. On one side of the support bracket 109, first connection hinges 110 are symmetrically installed. The first connection hinges 110 are rotatably connected to the support bracket 109. The support bracket 109 is fixedly installed on one side of the top of the installation bracket 101. By driving the first sprocket transmission assembly 105 and the inclined threaded rods 106 to rotate by the inclined motor 104, the inclined threaded sleeves 107 are lifted and moved on the outer sides of the inclined threaded rods 106 while driving the inclined rotating rods 108 to rotate, and under the action of the first connection hinges 110, the rotation of the support bracket 109 is realized.

[0038] The inner periphery of the support bracket 109 is fixedly installed with clamping sliding rods 111. The outer side of the clamping sliding rods 111 is slidably connected with clamping sliding sleeves 112. One side of the clamping sliding sleeves 112 is fixedly installed with clamping springs 113.

The top of one clamping sliding sleeve 112 is fixedly installed with a clamping sliding bracket 118. One side of the clamping sliding bracket 118 is symmetrically installed with support springs 119. The end of the support spring 119 is fixedly installed with a clamping inclined plate 120. One side of the top of the clamping inclined plate 120 is fixedly installed with a clamping top plate 121. One side of the bottom of the clamping top plate 121 is symmetrically installed with second connecting hinges 122. The outer sides of the two second connecting hinges 122 are rotatably connected with a clamping support plate 123. Both sides of the bottom of the clamping top plate 121 are symmetrically installed with pressing brackets 124. The inside of the pressing brackets 124 is fixedly installed with pressing sliding rods 125. The outer side of the pressing sliding rods 125 is slidably connected with pressing sliding sleeves 126.

By utilizing the sliding connection characteristics of the clamping sliding rods 111 and the clamping sliding sleeves 112 inside the support bracket 109, when supporting the steel structure crossbeam, the steel structure crossbeam can squeeze the clamping support tray 117 and drive the clamping support rods 116 and the clamping lifting plate 115 to descend. Under the action of the clamping rotating rod 114, the clamping sliding sleeve 112 drives the clamping sliding bracket 118 to move relatively. The steel structure crossbeam is initially clamped and limited by the support spring 119 and the clamping inclined plate 120. The steel structure crossbeam is limited by the second connecting hinge 122 and the clamping support plate 123 on one side of the clamping top plate 121. At the same time, by utilizing the elastic force of the pressing spring 127 inside the pressing bracket 124, the rotational support of the clamping support plate 123 can be realized, and the two sides of the steel structure crossbeam can be clamped and limited, improving the clamping stability of the steel structure crossbeam.

[0039] A longitudinal motor 129 is fixedly installed at the top of the installation bracket 101. The output end of the longitudinal motor 129 is fixedly connected to a longitudinal double-threaded rod 130. Symmetrically threaded sleeves 131 are threadedly connected to the outside of the longitudinal double-threaded rod 130. The top of the longitudinal threaded sleeve 131 is fixedly installed with a longitudinal bracket 132. One end of the longitudinal bracket 132 is fixedly installed with a transverse motor 133.

The welding device 138 is fixedly connected to the output end of the adjustment motor 137. The welding device 138 is rotatably connected to the welding bracket 136. By driving the longitudinal double-threaded rod 130 to rotate through the longitudinal motor 129, the two longitudinal threaded sleeves 131 drive the longitudinal bracket 132 to move relatively, and the longitudinal positions of the two welding devices 138 can be adjusted. At the same time, the transverse motor 133 is started to drive the transverse threaded rod 134 to rotate, so that the transverse threaded sleeve 135 drives the welding bracket 136 to move horizontally, and the adjustment motor 137 is started to drive the welding device 138 to rotate, so that the steel structure column and the steel structure cross beam can be spliced and welded, improving the welding accuracy. By adjusting the angle of the support bracket 109, steel structures at different angles can be adapted, facilitating the steel structure welding of industrial factories.

[0040] The climbing mechanism 2 includes a second motor cover 201. The second motor cover 201 is fixedly installed on one side of the bottom of the mounting bracket 101. On one side inside the second motor cover 201, a climbing motor 202 is fixedly installed. The output end of the climbing motor 202 is fixedly connected to a second sprocket drive assembly 203. At the top of the second sprocket drive assembly 203, climbing threaded rods 204 are symmetrically installed. On the outer sides of the two climbing threaded rods 204, climbing threaded sleeves 205 are threadedly connected. On the outer sides of the two climbing threaded sleeves 205, a climbing support plate 206 is fixedly installed. On one side of the middle of the climbing support plate 206, rotating brackets 207 are symmetrically installed. By driving the second sprocket drive assembly 203 and the climbing threaded rods 204 to rotate with the climbing motor 202, the climbing threaded sleeves 205 drive the climbing support plate 206 to move up and down. At the same time, starting the clamping motor 214 to drive the clamping double-threaded rod 215 to rotate, so that the two clamping threaded sleeves 216 drive the clamping limit plates 217 and the clamping arms 218 to move relatively, and the clamping and fixing of the steel structure column can be realized. When the clamping arm 218 on one side of the first clamping bracket 212 clamps and fixes the steel structure column, the clamping arm 218 on one side of the second clamping bracket 213 is loosened. When the clamping arm 218 on one side of the first clamping bracket 212 is loosened, the clamping arm 218 on one side of the second clamping bracket 213 clamps and fixes the steel structure column. Thus, the climbing function of the mounting bracket 101 can be realized, which is convenient for the mounting bracket 101 to move to the top of the steel structure column and cooperate with the tower crane for the positioning welding of the steel structure beam. There is no need for manual climbing to the top of the steel structure column, which improves the safety and convenience of the operation.

[0041] On the outer side of one side rotating bracket 207, a rotating motor 208 is fixedly installed. The output end of the rotating motor 208 is fixedly connected to a rotating worm 209. On one side of the rotating worm 209, a rotating worm gear 210 is meshed and connected. On one side of the rotating worm gear 210, a rotating plate 211 is fixedly installed. On the outer side of the rotating plate 211, first clamping brackets 212 are symmetrically installed. The second clamping bracket 213 is fixedly installed on one side of the top and bottom of the mounting bracket 101. At one end of each of the first clamping bracket 212 and the second clamping bracket 213, a clamping motor 214 is fixedly installed. The output end of the clamping motor 214 is fixedly connected to a clamping double-threaded rod 215. On the outer side of the clamping double-threaded rod 215, clamping threaded sleeves 216 are symmetrically and threadedly connected. On the outer side of the clamping threaded sleeve 216, a clamping limit plate 217 is fixedly installed. On the outer side of the clamping limit plate 217, a clamping arm 218 is fixedly installed. By driving the rotating worm 209 to rotate with the rotating motor 208, and using the meshing connection characteristic between the rotating worm 209 and the rotating worm gear 210, the rotation of the rotating plate 211 can be realized, so as to adjust the angle of the clamping arm 218 on one side of the first clamping bracket 212, which is convenient for steel structure welding at different angles.

[0042] Working principle: Before using a steel structure welding device for industrial plant construction, it is necessary to first check the overall condition of the device to ensure that it can work properly. According to Figure 1 - Figure 11 As shown, first, drive the second sprocket drive assembly 203 and the climbing threaded rod 204 to rotate by the climbing motor 202, so that the climbing thread sleeve 205 drives the climbing support plate 206 to move up and down. At the same time, start the clamping motor 214 to drive the clamping bidirectional threaded rod 215 to rotate, so that the two clamping thread sleeves 216 drive the clamping limit plate 217 and the clamping arm 218 to move relatively, and the clamping and fixing of the steel structure column can be realized. When the clamping arm 218 on one side of the first clamping bracket 212 clamps and fixes the steel structure column, the clamping arm 218 on one side of the second clamping bracket 213 is loosened. When the clamping arm 218 on one side of the first clamping bracket 212 is loosened, the clamping arm 218 on one side of the second clamping bracket 213 clamps and fixes the steel structure column, so that the climbing function of the mounting bracket 101 can be realized, which is convenient for the mounting bracket 101 to move to the top of the steel structure column and cooperate with the tower crane for the positioning welding of the steel structure beam. There is no need for manual climbing to the top of the steel structure column, which improves the safety and convenience of operation. By driving the rotating worm 209 to rotate by the rotating motor 208, and using the characteristic of the meshing connection between the rotating worm 209 and the rotating worm wheel 210, the rotation of the rotating plate 211 can be realized, so as to adjust the angle of the clamping arm 218 on one side of the first clamping bracket 212, which is convenient for steel structure welding at different angles.

[0043] Secondly, drive the first sprocket drive assembly 105 and the tilting threaded rod 106 to rotate by the tilting motor 104, so that the tilting thread sleeve 107 moves up and down outside the tilting threaded rod 106 and drives the tilting rotating rod 108 to rotate at the same time. Under the action of the first connecting hinge 110, the rotation of the support bracket 109 is realized. At the same time, by using the characteristic of the sliding connection between the clamping sliding rod 111 and the clamping sliding sleeve 112 inside the support bracket 109, when supporting the steel structure cross beam, the steel structure cross beam squeezes the clamping support tray 117 and drives the clamping support rod 116 and the clamping lifting plate 115 to descend. Under the action of the clamping rotating rod 114, the clamping sliding sleeve 112 drives the clamping sliding bracket 118 to move relatively. The steel structure cross beam is preliminarily clamped and limited by the support spring 119 and the clamping inclined plate 120. The steel structure cross beam is limited by the second connecting hinge 122 and the clamping support plate 123 on one side of the clamping top plate 121. At the same time, by using the elastic force of the compression spring 127 inside the pressing bracket 124, the rotational support of the clamping support plate 123 can be realized, and the two sides of the steel structure cross beam can be clamped and limited, improving the clamping stability of the steel structure cross beam.

[0044] Finally, the longitudinal motor 129 drives the longitudinal double-threaded rod 130 to rotate, causing the two longitudinal thread sleeves 131 to drive the longitudinal bracket 132 to move relatively, so as to adjust the longitudinal positions of the two welding devices 138. At the same time, the transverse motor 133 is started to drive the transverse threaded rod 134 to rotate, causing the transverse thread sleeve 135 to drive the welding bracket 136 to move transversely, and the adjustment motor 137 is started to drive the welding device 138 to rotate, so as to splice and weld the steel structure column and the steel structure cross beam, improving the welding accuracy. By adjusting the angle of the support bracket 109, it is possible to adapt to steel structures at different angles, facilitating the steel structure welding of industrial plants. By climbing, it is possible to adapt to the welding of steel structure plants with large spans and heights.
