Description

Technical Field

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

[0002] In the construction of steel structure buildings, steel beam welding is a key link, and its quality directly affects the safety and stability of the overall building. Traditional steel beam welding methods mostly rely on manual operation, which has high requirements for welders' skills. The welding quality is easily affected by human factors, and the efficiency is relatively low. At the same time, some simple welding equipment is difficult to accurately control welding parameters, resulting in uneven weld quality. Therefore, a steel beam welding device is now used for steel beam welding.

[0003] During the use of the existing steel beam welding device, first, through a hoisting device, two channel steels to be welded are hoisted to the welding platform. After being hoisted to the welding platform, the operator cleans the end faces to be welded. After the cleaning is completed, a welding flux is coated on the end faces of the two channel steels. After the cleaning and coating of the welding flux are completed, the two channel steels are aligned and abutted. At this time, the six-axis welding arm on the surface of the machine body is started to weld the butt joint of the channel steel.

[0004] The above solution still has some problems in actual application. In the actual application of the above steel beam welding device, during the process of manually coating the welding flux with a brush by the operator, it is difficult to ensure the uniformity of the welding flux coating. The coating amount in different areas may vary greatly, which will lead to uneven heat distribution during welding and affect the weld quality. Some areas may have welding defects such as pores and slag inclusions due to insufficient welding flux; on the other hand, the manual operation speed is slow, which will prolong the entire welding preparation time, reduce the welding efficiency, increase the time cost, and moreover, it is difficult to accurately control the coating range during manual coating, and the welding flux may be coated on non-welding areas, which not only causes waste of the welding flux, but also increases the workload of subsequent cleaning and may even cause unnecessary pollution to the surface of the channel steel.

[0005] Therefore, the present invention provides a steel beam welding device for steel structure building construction. Summary of the Invention

[0009] Preferably, during the process of the slider driving the fixing box to move downward, the fixing gear rotates along the fixing rack plate, thereby driving the rotating ring to rotate. The rotation of the rotating ring drives the push rod to move up and down under the limitation of the limiting ring. During the upward movement, the push rod drives the fixing disk to lift the steel ball, so that the storage cavity opened inside the storage box is communicated with the infiltration cavity to perform the work of adding the soldering flux. A protection plate is arranged inside the fixing box.

[0010] Preferably, during the process of the fixing disk lifting the steel ball, a mixing component inside the storage box will be triggered to work. The mixing component inside the storage box is used for stirring the soldering flux inside the storage box.

[0011] Preferably, the mixing component includes a card slot opened on the fixing disk. A card board is slidably arranged inside the storage box. One end of the card board fits with the card slot.

[0012] Preferably, when the rotating ring rotates to drive the fixed disk to jack up the steel ball, the clamping grooves on both sides of the fixed disk are clamped with the clamping plates in the storage box, so that the fixed disk drives the clamping plates to move upward. During the upward movement of the clamping plates, the connecting frame is driven to move upward. During the upward movement of the connecting frame, the auxiliary gears at both ends of the rotating paddle inside it will rotate along the auxiliary toothed plates, so as to stir the flux in the storage box.

[0013] Preferably, a telescopic spring is fixedly connected to the top wall of the storage box. A telescopic column is arranged inside the telescopic spring. The bottom ends of the telescopic spring and the telescopic column are both fixedly connected to the steel ball.

[0017] The beneficial effects of the present invention are as follows: 1. For the steel beam welding device used in the construction of steel structure buildings of the present invention, the flux is coated through the special sponges on both sides of the fixed box. During the downward movement of the slider, the push rod in the fixed box will be indirectly driven to move upward. The upward movement of the push rod will penetrate through the partition plate and push the elastically arranged steel ball in the storage box. The steel ball is the hole structure that seals the storage box and the fixed box. After the steel ball is jacked up, the storage box and the fixed box are connected, and then the storage box replenishes the flux to the fixed box. Because the flux in the fixed box may not be enough during the subsequent horizontal coating of the channel steel, replenishment is carried out during the downward movement, which plays a better role in flux coating work. In addition, when the steel ball is jacked up, it will also trigger the mixing assembly to stir the flux in the storage box to ensure its uniformity.

[0018] 2. For the steel beam welding device used in the construction of steel structure buildings according to the present invention, when the rotating ring drives the fixed disk to jack up the steel ball, the fixed disk is clamped with the clamping plate, so that the fixed disk drives the clamping plate and the connecting frame to move upward. During the upward movement of the connecting frame, the auxiliary gear of the rotating paddle inside it rotates along the auxiliary toothed plate, and the flux in the storage tank can be automatically stirred, avoiding the precipitation or uneven distribution of the flux, ensuring its stable performance, guaranteeing the quality of subsequent processes, and improving production efficiency.

[0019] 3. For the steel beam welding device used in the construction of steel structure buildings according to the present invention, side plates are fixedly connected to both sides of the sliding block. When coating work is carried out, the fixed box is located between the ends of the channel steel by driving the sliding block. At this time, the one-way inclined plates on both sides of the side plates are in contact with the inclined grooves on both sides of the convex plate, so that the two channel steels are separated. Then, after the flux coating is completed, the one-way inclined plates are separated from the inclined grooves of the convex plate. At this time, the two positioning frames approach and abut against each other under the action of their respective positioning springs, so as to butt the channel steels. After the butting is completed, the six-axis welding head is used for welding work, achieving the effect of automatic positioning. After welding is completed, the one-way inclined plates are used to squeeze the inclined grooves, so that the two positioning frames move away, but the welded channel steels can still be butted together and slide inside the two positioning frames, improving the welding efficiency.

[0022] In order to make the technical means, creative features, achieved purposes and functions of the present invention easy to understand, the present invention will be further described below in conjunction with specific implementation manners.

[0023] Example 1: As Figures 1 to 9 shown, a steel beam welding device for steel structure building construction described in an embodiment of the present invention includes a machine body 1. A base 5 is fixedly connected to the upper surface of the machine body 1. A six-axis welding head 51 is fixedly connected above the base 5. A positioning component is arranged on the upper surface of the machine body 1. The positioning component includes a positioning plate 3 fixedly connected to the upper surface of the machine body 1. A positioning frame 32 is slidably connected to one side of the positioning plate 3. A channel steel 4 is placed inside the positioning frame 32; A coating component is slidably arranged on the upper surface of the machine body 1. The coating component includes a sliding groove 231 opened on the upper surface of the machine body 1. A sliding block 2 is slidably connected in the sliding groove 231. A fixed frame 22 is fixedly connected to the upper surface of the sliding block 2. A lead screw 24 is rotatably connected inside the fixed frame 22. A slide block 25 is slidably connected to the circumferential surface of the lead screw 24. A fixed box 26 is fixedly connected to one side of the slide block 25 through a fixed shaft 211. Special sponges are arranged on both sides of the fixed box 26 for coating the soldering flux; The upper surface of the fixed box 26 is fixedly connected with a storage box 27 through a partition plate 219. A dosing component is arranged in the fixed box 26. The dosing component includes a rotating ring 210 rotatably arranged on one side of the fixed box 26. A rotating rod 212 is fixedly connected to the circumferential surface of the rotating ring 210. A push rod 214 is fixedly connected to the circumferential surface of the rotating rod 212. The top end of the push rod 214 is fixedly connected with a fixed disk 222. A limiting ring 213 is arranged in the fixed box 26 to limit the rotating rod 212. The top wall of the storage box 27 is elastically connected with a steel ball 217. The steel ball 217 abuts against the fixed disk 222. After the steel ball 217 is lifted, the storage box 27 is communicated with the fixed box 26, and a mixing component is triggered during the lifting process of the steel ball 217 to stir the flux in the storage box 27.

[0024] Specifically, in the actual application of the above steel beam welding device, during the process of manually applying flux with a brush by the operator, it is difficult to ensure the uniformity of flux application manually. The application amounts in different areas may vary greatly, which will lead to uneven heat distribution during welding, affecting the weld quality. Welding defects such as pores and slag inclusions may occur in some areas due to insufficient flux; on the other hand, the manual operation speed is slow, which will lengthen the entire welding preparation time, reduce the welding efficiency, increase the time cost, and moreover, it is difficult to accurately control the application range manually, and the flux may be applied to non-welding areas, which not only causes waste of flux, but also increases the workload of subsequent cleaning, and may even cause unnecessary pollution to the surface of the channel steel 4; Therefore, the present invention solves the above problems by setting the above structure. First, the channel steel 4 is placed in the positioning frame 32, and precise positioning is achieved by using the positioning component. Subsequently, the sliding block 2 is driven to slide along the sliding groove 231 for the coating work. During the sliding process of the sliding block 2, the fixed frame 22 fixedly connected to its upper surface will be started to slide at the same time. After the fixed frame 22 moves between the two channel steels 4, the screw rod 24 is rotated to make the slider 25 move downward for the coating work. The flux is applied through the special sponges on both sides of the fixed box 26. During the downward movement of the slider 25, the push rod 214 in the fixed box 26 will be indirectly driven to move upward. The upward movement of the push rod 214 will penetrate the partition plate 219 and push the elastically arranged steel ball 217 in the storage box 27. The steel ball 217 is a hole structure that seals between the storage box 27 and the fixed box 26. After the steel ball 217 is lifted, the storage box 27 is communicated with the fixed box 26, and then the storage box 27 replenishes the flux to the fixed box 26. Because during the subsequent horizontal coating of the channel steel 4, the flux in the fixed box 26 may not be enough, replenishment is carried out during the downward movement, which plays a better role in the flux coating work. In addition, when the steel ball 217 is lifted, the mixing component will also be triggered to stir the flux in the storage box 27 to ensure its uniformity; The position of the channel steel 4 is ensured to be accurate through the positioning component, improving the welding precision and quality. The coating component can flexibly adjust the coating position through structures such as the sliding groove 231 and the lead screw 24, and the special sponge coats evenly, ensuring the welding effect. The dosing component can control the flux flow rate, timely supplement the flux, and at the same time trigger the mixing component to stir the flux to prevent it from precipitating and stratifying, ensuring the stable performance of the flux and improving the welding quality. The overall equipment integrates the functions of welding and coating, has a high degree of automation, is easy to operate, can effectively improve production efficiency, reduce labor costs, and has high practical value in the field of welding processing.

[0025] As Figures 5 to 7 shown, the dosing component of this embodiment further includes a fixed gear 28 fixedly connected to one side of the rotating ring 210. The rotating ring 210 is sleeved on the circumferential surface of the fixed shaft 211, and a fixed rack plate 29 is fixedly connected to the fixed frame 22 corresponding to the position of the fixed gear 28.

[0026] Specifically, during the process of the slider 25 driving the fixed box 26 to move downward, the fixed gear 28 rotates along the fixed rack plate 29, thereby driving the rotating ring 210 to rotate. The rotation of the rotating ring 210 drives the push rod 214 to move up and down under the limitation of the limiting ring 213. During the upward movement, the push rod 214 drives the fixed disk 222 to lift the steel ball 217, so that the storage cavity 221 opened inside the storage tank 27 is communicated with the infiltration cavity 220, and the work of filling the flux is carried out. A protection plate 218 is arranged inside the fixed box 26. By driving the dosing component during the process of coating the flux, the flux is timely supplemented, the welding efficiency is improved, and the output is increased.

[0027] As Figure 7 shown, during the process of the fixed disk 222 of this embodiment lifting the steel ball 217, it will trigger the mixing component inside the storage tank 27 to work. The mixing component inside the storage tank 27 is used for stirring the flux inside the storage tank 27. The mixing component includes clamping grooves 223 opened on both sides of the fixed disk 222. A clamping plate 224 is slidably arranged inside the storage tank 27. One end of the clamping plate 224 fits with the clamping groove 223. A connecting frame 225 is fixedly connected to the surface of the clamping plate 224. A rotating paddle 226 is rotatably connected inside the connecting frame 225. Auxiliary gears 228 are fixedly connected to both ends of the rotating paddle 226. The auxiliary gears 228 are fixedly connected to the rotating paddle 226 through auxiliary shafts 229. Auxiliary rack plates 227 are fixedly connected to the storage tank 27 corresponding to the positions of the auxiliary gears 228.

[0028] Specifically, when the rotating ring 210 rotates to drive the fixed disk 222 to lift the steel ball 217, the clamping grooves 223 on both sides of the fixed disk 222 are clamped with the clamping plates 224 in the storage box 27. Then, the fixed disk 222 drives the clamping plates 224 to move upward. During the upward movement of the clamping plates 224, the connecting frame 225 is driven to move upward. During the upward movement of the connecting frame 225, the auxiliary gears 228 at both ends of the rotating paddle 226 inside it will rotate along the auxiliary toothed plates 227, thereby stirring the flux in the storage box 27; When the rotating ring 210 drives the fixed disk 222 to lift the steel ball 217, by using the clamping connection between the fixed disk 222 and the clamping plate 224, the fixed disk 222 drives the clamping plate 224 and the connecting frame 225 to move upward. During the upward movement of the connecting frame 225, the auxiliary gears 228 of the rotating paddle 226 inside it rotate along the auxiliary toothed plates 227, which can automatically stir the flux in the storage box 27, avoid the precipitation or uneven distribution of the flux, ensure its stable performance, guarantee the quality of subsequent processes, and improve production efficiency.

[0029] As Figure 7 shown, a telescopic spring 216 is fixedly connected to the top wall of the storage box 27 in this embodiment. A telescopic column 215 is arranged inside the telescopic spring 216. The bottom ends of the telescopic spring 216 and the telescopic column 215 are both fixedly connected to the steel ball 217. A number of groups of limiting strips 230 are also fixedly connected to the inner wall of the storage box 27 to assist the sliding of the clamping plate 224.

[0030] Specifically, when the rotating ring 210 rotates to drive the fixed disk 222 to lift the steel ball 217, the steel ball 217 receives an upward acting force. At this time, the telescopic spring 216 and the telescopic column 215 fixedly connected to the steel ball 217 will be compressed. The telescopic column 215 plays a guiding role inside the telescopic spring 216 to ensure the stable movement of the steel ball 217 along a specific direction. At the same time, a number of groups of limiting strips 230 on the inner wall of the storage box 27 provide a track for the sliding of the clamping plate 224. When the clamping plate 224 moves upward driven by the fixed disk 222, it will slide along the limiting strips 230, thereby ensuring the smoothness and accuracy of the movement of the clamping plate 224; making the operation of the entire device more smooth and reliable, improving the working precision and stability of the equipment, and guaranteeing the smooth progress of the production process.

[0031] Embodiment 2: As Figures 1 to 9 shown, compared with Embodiment 1, another implementation manner of the present invention is as follows: Side plates 21 are fixedly connected to both sides of the surface of the sliding block 2. One-way inclined plates 23 are fixedly connected to both sides of the side plates 21. A positioning spring 31 is fixedly connected to one side of the positioning plate 3. A positioning rod 33 is fixedly connected inside the positioning spring 31. A convex plate 34 is fixedly connected to one end of the positioning spring 31 and the positioning rod 33. The upper surface of the convex plate 34 is fixedly connected to the positioning frame 32. An inclined groove 35 is opened at one end of the convex plate 34.

[0032] Specifically, side plates 21 are fixedly connected to both sides of the sliding block 2. When performing the coating work, the fixed box 26 is positioned between the ends of the channel steel 4 by driving the sliding block 2. Specifically, as shown in the appendix Figure 2 As shown, at this time, the one-way inclined plates 23 on both sides of the side plate 21 are in contact with the inclined grooves 35 on both sides of the convex plate 34, causing the two channel steels 4 to be separated. Then, after the flux coating is completed, the one-way inclined plates 23 are disengaged from the inclined grooves 35 of the convex plate 34. At this time, the two positioning frames 32 approach and contact each other under the action of their respective positioning springs 31, thereby docking the channel steels 4. After the docking is completed, the six-axis welding head 51 performs the welding work, achieving the effect of automatic positioning. After the welding is completed, the one-way inclined plates 23 squeeze the inclined grooves 35, causing the two positioning frames 32 to move away. However, the welded channel steels 4 can still be docked together and slide within the two positioning frames 32, improving the welding efficiency.

[0033] As Figure 4 As shown, a sealing assembly is provided inside the body 1 of this embodiment. The sealing assembly includes a sealing plate 14 elastically arranged inside the body 1. The splicing of the two sealing plates 14 seals the sliding groove 231. A first cavity 11 and a second cavity 12 are formed inside the body 1. A first spring 13 and a second spring 15 are fixedly connected inside the first cavity 11 and the second cavity 12 respectively. The first spring 13 is fixedly connected to the sealing plate 14, and the second spring 15 is fixedly connected to the auxiliary plate 16.

[0034] Specifically, in the normal state, the first spring 13 elastically arranges the sealing plate 14 inside the body 1 by virtue of its own elastic force. The two sealing plates 14 are spliced together to seal the sliding groove 231. When the conical sliding block 2 moves along the sliding groove 231 and then pushes the sealing plate 14 to move to change the sealing state of the sliding groove 231, the sealing plate 14 compresses the first spring 13 and thus changes its position. At the same time, the auxiliary plate 16 is arranged at both ends of the sliding groove 231. Under the support of the second spring 15, the conical opening between the sealing sliding block 2 and the sealing plate 14 is sealed. Specifically, as shown in the appendix Figure 4 As shown, when welding, the sliding groove 231 is sealed to prevent welding slag from falling into the sliding groove 231, ensuring the sealing effect while extending the service life of the equipment.

[0035] Working principle: First, place the channel steel 4 in the positioning frame 32, and use the positioning component to achieve precise positioning. Subsequently, drive the sliding block 2 to slide along the sliding groove 231 for coating work. During the sliding process of the sliding block 2, the fixed frame 22 fixedly connected to its upper surface will be started to slide simultaneously. After the fixed frame 22 moves between the two channel steels 4, rotate the lead screw 24 to make the slider 25 move downward for coating work. The special sponges on both sides of the fixed box 26 are used for flux coating. During the process of the slider 25 driving the fixed box 26 to move downward, the fixed gear 28 rotates along the fixed rack plate 29, thereby driving the rotating ring 210 to rotate. The rotation of the rotating ring 210 drives the push rod 214 to move up and down under the limitation of the limiting ring 213. During the upward movement, the push rod 214 drives the fixed disk 222 to jack up the steel ball 217. The steel ball 217 is a hole structure between the sealed storage box 27 and the fixed box 26, so that the storage cavity 221 opened inside the storage box 27 is communicated with the infiltration cavity 220 for adding flux work. A protection plate 218 is arranged inside the fixed box 26. By driving the dosing component during the flux coating process, the flux is replenished in time, improving the welding efficiency and increasing the output; because during the subsequent horizontal coating of the channel steel 4, the flux in the fixed box 26 may not be enough, so replenishment is carried out during the descent process, which plays a better role in flux coating work; When the steel ball 217 is jacked up, it will also trigger the mixing component to stir the flux in the storage box 27 to ensure its uniformity. Specifically, during the process of the rotating ring 210 rotating to drive the fixed disk 222 to jack up the steel ball 217, the card slots 223 on both sides of the fixed disk 222 are clamped with the clamping plates 224 in the storage box 27, so that the fixed disk 222 drives the clamping plates 224 to move upward. During the upward movement of the clamping plates 224, the connecting frame 225 is driven to move upward. During the upward movement of the connecting frame 225, the auxiliary gears 228 at both ends of the rotating paddle 226 inside it will rotate along the auxiliary toothed plate 227, thereby stirring the flux in the storage box 27; When the rotating ring 210 drives the fixed disk 222 to jack up the steel ball 217, by using the clamping of the fixed disk 222 and the clamping plate 224, the fixed disk 222 drives the clamping plate 224 and the connecting frame 225 to move upward. During the upward movement of the connecting frame 225, the auxiliary gears 228 of the rotating paddle 226 inside it rotate along the auxiliary toothed plate 227, which can automatically stir the flux in the storage box 27, avoid flux precipitation or uneven distribution, ensure its stable performance, guarantee the quality of subsequent processes, and improve production efficiency; In addition, side plates 21 are fixedly connected to both sides of the sliding block 2. When coating work is carried out, the fixed box 26 is located between the ends of the channel steel 4 by driving the sliding block 2. Specifically, as shown in the appendix Figure 2As shown, at this time, the one-way inclined plates 23 on both sides of the side plate 21 are in contact with the inclined grooves 35 on both sides of the convex plate 34, so that the two channel steels 4 are separated. Then, after the flux coating is completed, the one-way inclined plates 23 are disengaged from the inclined grooves 35 of the convex plate 34. At this time, the two positioning frames 32 approach and contact each other under the action of their respective positioning springs 31, so as to butt the channel steels 4. After the butting is completed, the welding work is carried out by the six-axis welding head 51, achieving the effect of automatic positioning. After the welding is completed, the one-way inclined plates 23 are used to squeeze the inclined grooves 35, so that the two positioning frames 32 move away. However, the welded channel steels 4 can still be butted together and slide within the two positioning frames 32, improving the welding efficiency.

[0036] The foregoing shows and describes the basic principles, main features and advantages of the present invention.
