Description

Technical Field

[0001] The present invention relates to the technical field of welding, and specifically to a welding tool for steel structure production based on a boiler lifting platform. Background Art

[0002] In the construction of building steel structure projects, welding technology is a very important connection method in steel structure projects. With the continuous development of engineering technology, people's requirements for the quality of construction projects are also getting higher and higher. In steel structure projects where welding connection is the main connection method, welding quality is an important indicator for evaluating the quality of steel structure projects. The welding process of steel structures is a process of uneven heating and cooling. During welding, the temperature of the weld and its vicinity is very high, while most of the metal in the distance is not heated. The expansion and contraction of the main body metal are uneven. After cooling, the weld produces different degrees of shrinkage and internal stress (longitudinal and transverse), resulting in various deformations of the welded structure.

[0003] When welding steel materials, especially for the welding of steel structures of the frame type, since the frame is composed of multiple steel bars, it is necessary for workers to manually align each steel bar to the welding position during welding, and then weld it by machine. And if the length of the steel bar is too long during welding, it is necessary for workers to hold it by hand during welding. Therefore, doing so for a long time is likely to cause harm to the eyes and skin, endangering human health.

[0004] In view of this, the present invention proposes a welding tool for steel structure production based on a boiler lifting platform to solve the above technical problems. Summary of the Invention

[0010] As a preferred technical solution of the present invention, a plum blossom-shaped card slot is provided at the bottom of the threaded rod. The bottom of the sliding rod is designed as a plum blossom-shaped card block. The plum blossom-shaped card block on the upper part of the sliding rod is engaged with the plum blossom-shaped card slot.

[0011] As a preferred technical solution of the present invention, a slider I is slidably connected to the top of the fixing rod I through a chute. A push rod is fixed to the surface of the slider I.

[0028] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0029] Please refer to Figure 1-2 and Figure 4-5 As shown, a welding tool for steel structure production based on a boiler lifting platform includes a steel body 1. A steel bar 101 is welded on the surface of the steel body 1, and a clamping assembly is provided on the surface of the steel body 1. The clamping assembly includes a clamping block I 201. The clamping block I 201 clamps on the surface of the steel body 1. A pushing block 207 is fixed on one side of the clamping block I 201. A fixed rod I 2071 is slidably connected inside the pushing block 207. The end of the fixed rod I 2071 is slidably connected with a clamping frame 202. A threaded rod 2103 is rotatably provided inside the clamping frame 202. A slide block II is slidably connected inside the clamping frame 202. The slide block II is fixed to the end of the fixed rod I 2071. The threaded rod 2103 passes through the middle of the slide block II and is threadedly connected thereto. A vertical block 2011 is slidably connected at the middle position of the clamping block I 201. A fixed rod III 212 is fixed to the bottom of the vertical block 2011. The end of the fixed rod III 212 is hinged with a tensile frame 205. The end of the tensile frame 205 is hinged with a base 203. Two clamping blocks II 204 are slidably connected to the top of the base 203. The bottom of the clamping block II 204 passes through the adjusting rod 211 inside through a fixed block, and a rotating block is fixed to the end of the adjusting rod 211.

[0030] The steel bar 101 is clamped at the top of the base 203 by the clamping block II 204. The pushing block 207 and the fixing rod I 2071 are respectively connected to the upper and lower sides of the clamping block I 201 and the clamping frame 202. The bottom of the pushing block 207 is fixed to the pushing block 207 on the lower surface of the clamping block I 201 through the connecting rod II 206. A set of oppositely arranged thread grooves are provided on the surface of the adjusting rod 211; a sliding rod 210 is slidably connected inside the threaded rod 2103. A sleeve handle 208 is slidably connected to the upper surface of the sliding rod 210. Two symmetrically arranged U-shaped rods 2081 are fixed on the surface of the sleeve handle 208. A rotating ring 209 is rotatably connected to the surface of the fixing rod I 2071; the upper end surface of the sliding rod 210 is provided with sliding grooves 2106 of different lengths. The bottom of the sleeve handle 208 is fixed with a U-shaped rod 2081. The bottom of the U-shaped rod 2081 is elastically connected with a plug block. A plug slot I corresponding to the plug block is provided inside the shorter sliding groove 2106; a plum blossom-shaped clamping slot is provided at the bottom of the threaded rod 2103. The bottom of the sliding rod 210 is designed with a plum blossom-shaped clamping block. The plum blossom-shaped clamping block on the upper sliding part of the sliding rod 210 is engaged with the plum blossom-shaped clamping slot.

[0031] When welding the steel bar 101, the sleeve handle 208 slides upward on the top of the sliding rod 210. When sliding to the short slot position of the sliding groove 2106, then rotate the sleeve handle 208 so that the U-shaped rod 2081 is inserted into the short slot. Then continue to slide upward and at the same time lift the sliding rod 210 upward. When the sliding rod 210 moves upward, the plum blossom-shaped clamping block at the bottom is engaged with the plum blossom-shaped clamping slot at the bottom of the threaded rod 2103. Then rotate the sleeve handle 208 and drive the threaded rod 2103 to rotate at the same time. The threaded rod 2103 rotates to adjust the distance between the two clamping blocks I 201 through the slider II. Adjust the clamping distance between the clamping blocks I 201 according to the thickness of the steel body 1, so that the clamping blocks I 201 can adapt to the thickness of the steel body 1 when clamping; at the same time, stretch the stretching frame 205 to push the base 203 forward to the middle position at the bottom of the steel bar 101. The stretching length of the stretching frame 205 can be adjusted through the setting of the stretching frame 205, and it is adjusted according to the length of the steel bar 101, so that the center of gravity of the steel bar 101 can be stabilized when supporting the bottom of the steel bar 101 and it can be kept stable during welding; then rotate the adjusting rod 211 through the rotating block. The fixing block at the bottom of the clamping block II 204 is located inside the adjusting rod 211. The adjusting rod 211 rotates to make the two clamping blocks II 204 move on the top of the base 203, clamp the steel bar 101 to ensure the stability of the steel bar 101 during welding, and slide on the surface of the steel body 1 through the clamping block I 201 to adjust the welding position of the steel bar 101.

[0032] Embodiment 2, on the basis of Embodiment 1,

[0033] As a specific implementation manner of the present invention, please refer to Figure 3 and Figure 6-8As shown in the figure, a slider I 2102 is slidably connected to the top of the fixed rod I 2071 through a chute. A push rod 2101 is fixed on the surface of the slider I 2102. The end of the push rod 2101 is fixed to the top of the push block 207. A fixed rod II 2091 is fixed to the top of the rotating ring 209. The fixing position of the fixed rod II 2091 corresponds to the U-shaped rod 2081 and is stuck inside it. A moving rod 2132 is slidably connected inside the fixed rod III 212. The end of the moving rod 2132 is slidably connected to a moving plate 213. A spring is fixed on one side of the moving plate 213, and the spring is fixed to the bottom of one of the vertical blocks 2011. The moving plate 213 is of a special-shaped structure. The other inclined surface of the moving plate 213 contacts a roller 2131. The bottom of the sliding rod 210 is fixed to the roller 2131 through a connecting rod I.

[0034] By sliding the sleeve handle 208 down at the top of the sliding rod 210, when it slides to the bottom of the long slot of the sliding slot 2106 and continues to slide down, the sliding rod 210 slides inside the threaded rod 2103 to separate the plum blossom-shaped clamping block from the plum blossom-shaped clamping slot. Then the U-shaped rod 2081 penetrates through the fixed rod II 2091, making the fixed rod II 2091 located in the middle of the U-shaped rod 2081. Then rotate the sleeve handle 208, and at the same time, the fixed rod II 2091 and the rotating ring 209 rotate simultaneously. The position of the convex block on the surface of the rotating ring 209 contacts the slider I 2102 and pushes the slider I 2102 to move towards the position of the push block 207. The push block 207 and the clamping block I 201 are pushed to move simultaneously through the push rod 2101, which can be adjusted according to the width of the steel bar 101, avoiding the narrow spacing between the two groups of clamping blocks I 201 causing obstacles when the steel bar 101 is supported and clamped at the bottom. Through the setting of the long and short slots of the sliding slot 2106, when the spacing of the clamping blocks I 201 is adjusted, then move the sleeve handle 208 upwards to the position of the short slot and rotate it so that the U-shaped rod 2081 is located in the short slot. Then continue to move the sleeve handle 208 upwards and drive the sliding rod 210 to move upwards at the same time so that the plum blossom-shaped clamping block engages with the plum blossom-shaped clamping slot, making the U-shaped rod 2081 withdraw from the fixed rod II 2091. Then rotate the sleeve handle 208 and drive the sliding rod 210 and the threaded rod 2103 to rotate simultaneously to adjust the height of the clamping block I 201, so as to avoid rotating the rotating ring 209 at the same time when adjusting the height of the clamping block I 201, which affects the spacing of the clamping blocks I 201. Through the setting of the U-shaped rod 2081 and the insertion block at the bottom of the U-shaped rod 2081, when the U-shaped rod 2081 is located inside the short slot, the insertion block can be inserted into the slot I at the bottom of the short slot, which can fix the sleeve handle 208 when it moves upwards and prevent it from sliding down when released.
