Description

Technical Field

[0001] This invention relates to the technical field of steel structure welding, and in particular to a welding surface treatment device and method for steel structure engineering. Background Technology

[0002] Steel structure engineering is an engineering structural system that uses steel (such as steel plates, steel sections, steel pipes, etc.) as the main load-bearing components. It has the characteristics of high strength, light weight, fast construction speed and recyclability, and is widely used in construction, bridges, industrial facilities and other fields.

[0003] Automatic and semi-automatic arc welding are core welding technologies in steel structure engineering. Both replace the manual wire feeding of traditional manual arc welding with mechanized wire feeding (or semi-automatic control parameters), significantly improving welding efficiency, stability and adaptability.

[0004] Automatic arc welding: During the welding process, the wire feeding, arc movement, and parameter adjustment (current / voltage / speed) are all completed automatically by machinery / robots, which is suitable for the mass production of regular, long straight welds.

[0005] Chinese patent CN120079968B discloses an automatic welding robot for steel structures, including a frame with a movable welding torch and a wire feeding mechanism. The wire feeding mechanism includes a processing box containing a wire cleaning mechanism. The wire cleaning mechanism includes a fixed first support plate, which is fixedly connected to the processing box. A water supply pipe and a brush are located on the upper side of the first support plate, with one end of the brush rotatably connected to the first support plate. This invention improves the cleaning effect by using a brush and water supply pipe to clean the welding wire, significantly enhancing the cleaning efficiency. A nozzle mounting base with a nozzle is used to dry the welding wire by blowing hot air, and the absorbent cotton ring on the water absorption assembly further enhances the drying effect.

[0006] The aforementioned related technologies and existing technologies have the following defects in steel structure welding: After arc welding, the oxide layer generated at the weld joint needs to be cleaned. If the cleaning is carried out after the steel structure is completely welded, the long interval will make the oxide layer difficult to separate. In order to clean in time, the existing technology will knock the weld joint at the same time after the weld joint. However, due to the short inspection time, the weld joint will not be completely solidified. At this time, knocking will reduce the strength of the weld joint and cause damage to the weld joint. Summary of the Invention

The two rod-shaped structures of the fixed frame are rotatably inserted with threaded rods on their inner sides, and the movable frame is threadedly sleeved on the outer surface of the threaded rods.

The other end of the force-bending rod is bent vertically away from the arc welding head and then bent vertically toward the moving block. A vibrating wheel is provided on the side of the force-bending rod that is bent vertically toward the moving block and close to the arc welding head. Multiple evenly distributed V-shaped grooves are opened on the circumference of the vibrating wheel. A drive shaft is coaxially mounted with the vibrating wheel and is rotatably mounted on the side of the moving block.

[0014] Optionally, the driving component further includes: A drive prism, which is coaxially mounted with the drive shaft; A control board, on one side of which is mounted a drive telescopic cylinder, which drives the control board to move relative to the moving block, and the drive telescopic rod is connected to the moving block; The main sleeve prism is slidably sleeved on the outside of the drive prism, and the control plate is rotatably sleeved on the outer surface of the main sleeve prism. The control plate is rotatably sleeved on the outer surface of the secondary sleeve shaft, and the main sleeve shaft and the secondary sleeve shaft are driven by a conveyor belt. The driven prism is coaxially sleeved on the outer surface of the transmission shaft. The driven prism and the inner side of the secondary sleeve prism are matched in shape. The transmission shaft is coaxially located inside the secondary sleeve prism.

[0015] Optionally, two inner disks are coaxially sleeved on the outside of the drive shaft, and the gear parts of the two gear tooth plate meshing assemblies are respectively rotatably sleeved on the outside of the two inner disks. Multiple circumferentially distributed arc-shaped blocks are fixed on the outer circumferential surface of the inner disks, and an arc-shaped limiting groove is opened on the inner ring surface of the gear part of the gear tooth plate meshing assembly. The number of arc-shaped limiting grooves is equal to the number of arc-shaped blocks. Multiple arc-shaped blocks are located one-to-one inside multiple arc-shaped limiting grooves, and the arc angle of the arc-shaped limiting grooves is greater than the arc angle of the arc-shaped blocks.

[0016] Optionally, a supporting bending rod is installed on one side of the stressed bending rod, and a suspended support plate is provided between the supporting bending rod and the stressed bending rod.

[0017] Optionally, an air jet is installed at an angle on one side of the arc welding head, with the air outlet of the air jet facing the welding end of the arc welding head.

[0018] The method for treating welded surfaces in steel structure engineering includes the following steps: S1. Fix the steel structure to be welded to both sides of the welding unit, and at the same time control the contact surface of the two steel structures to be located in the same vertical plane of the two welding units. S2. The welding drive console controls two welding processing units located at two adjacent welding surfaces of the steel structure respectively; S3. The drive component first controls the movement of the arc welding head relative to the corresponding weld seam of the steel structure for welding; S4. After the arc welding head completes welding on one side of the steel structure, control the arc welding head to stop welding, and drive the component to control the arc welding head to reset to the start end of the weld. S5. The control drive component controls the hammering and cleaning component to hammer the weld seam, and at the same time controls the hammering and cleaning component to move again along the weld seam direction during the hammering to clean the surface of the weld seam that was previously passed through.

[0019] In summary, the present invention has the following beneficial technical effects: This invention utilizes the coordinated use of a frame assembly and a hammering and cleaning assembly. When the drive assembly controls the arc welding head to weld, the hammering and cleaning assembly is controlled not to hammer the weld, allowing sufficient time for the weld to solidify. After welding is completed on one side of the steel structure, the arc welding head is reset, and then the drive assembly controls the hammering and cleaning assembly to gradually hammer and clean the weld from the start of the weld along the welding path. This ensures that the weld has solidified when the hammering and cleaning assembly strikes, while also preventing the weld from being left unattended for too long and becoming difficult to clean.

[0020] This invention utilizes the combined use of a support bend and a suspended support plate. When the drive assembly controls the movement of the arc welding head for welding, the support bend is positioned at the horizontal end of the suspended support plate, and the control hammer rod is disengaged from the weld position, so that the hammer rod does not apply external force to the unsolidified weld.

[0021] This invention utilizes the combined use of an inner disc, an arc-shaped limiting groove, and an arc-shaped block. When adjusting the total length between the fixed frame and the movable frame, the corresponding two toothed plate parts move relative to each other. Since misalignment may occur during the movement of the two toothed plate parts, when the gear part meshes with the moved toothed plate part, the arc-shaped block on the inner side of the gear part moves within the arc-shaped limiting groove. This allows the gear part to compensate for the misalignment distance of the toothed plate part through deflection, enabling the gear part to mesh with the corresponding moved toothed plate part without causing misalignment and jamming.

[0022] This invention utilizes a jet nozzle that sprays air onto the welding section during arc welding. The airflow removes impurities from the welding section, reducing internal impurities during welding. Simultaneously, after welding, the airflow carries away heat from the welding section, increasing its cooling rate. When the striking rod strikes the welding section, the airflow blows away the weld slag, further improving the cleanliness of the welding section. Attached Figure Description

[0025] The following is in conjunction with the appendix Figures 1-9 The present invention will be described in further detail below.

[0026] This invention discloses a welding surface treatment device for steel structure engineering. For example... Figure 1 As shown, the welding drive console 1 also includes two welding processing units 2, which are vertically arranged. The welding drive console 1 can drive the two welding processing units 2 to move up and down and left and right.

[0027] In this embodiment, as Figure 2 As shown, the welding processing unit 2 includes a frame assembly 21, a drive assembly 22, an arc welding head 23, and a hammering and cleaning assembly 24.

[0028] The frame component 21 is connected to the welding drive console 1, which can drive the frame component 21 to move up and down and left and right.

[0029] The welding drive control console 1 is equipped with a power source to control the up-down and left-right movement of the two frame components 21. Preferably, the power source is a hydraulic cylinder, an electric cylinder, or a motor-driven threaded shaft and a meshing block that meshes with it. The meshing block and the threaded shaft produce linear movement. By setting lateral and vertical power drives, the frame components 21 are controlled to move up-down and left-right, thus changing the position of the corresponding structures.

[0030] The drive assembly 22 is sleeved and installed on the outside of the frame assembly 21. The drive assembly 22 moves with power on the outside of the frame assembly 21. The arc welding head 23 is connected to the drive assembly 22. The drive assembly 22 drives the arc welding head 23 to move along the path of the frame assembly 21.

[0031] The arc welding head 23 has a welding wire threaded inside, and the arc welding head 23 can control the welding wire to perform welding treatment on the steel structure in contact.

[0032] The hammering and cleaning component 24 is installed on the outside of the arc welding head 23. The hammering and cleaning component 24 slides elastically relative to the arc welding head 23. The driving component 22 can drive the hammering and cleaning component 24 to hammer the welding surface of the weld seam of the arc welding head 23.

[0033] In this embodiment, as Figures 3-5 As shown, the drive assembly 22 includes a moving block 221, a drive shaft 222, and a gear and tooth plate meshing assembly 223.

[0034] The arc welding head 23 is fixed to the movable block 221, which is slidably sleeved on the outside of the frame assembly 21. The drive shaft 222 is rotatably mounted on the surface of the movable block 221 and rotates relative to the movable block 221. In this embodiment, the movable block 221 is equipped with a motor that applies power to the drive shaft 222, thereby generating rotational power to the drive shaft 222.

[0035] Two gear and tooth plate meshing assemblies 223 are provided. Each gear and tooth plate meshing assembly 223 consists of meshing gears and tooth plates. The gear part of the gear and tooth plate meshing assembly 223 is coaxially mounted with the drive shaft 222, and the tooth plate part of the gear and tooth plate meshing assembly 223 is connected to the frame assembly 21.

[0036] As the drive shaft 222 rotates, it drives the connected gear part to rotate. The gear part meshes with the gear plate part, causing the moving block 221 to slide on the outside of the frame assembly 21, thereby changing the position of the arc welding head 23, so that the arc welding head 23 can stably weld the steel structure in a straight line, improving the welding accuracy.

[0037] The frame assembly 21 includes a fixed frame 211 and a movable frame 212. The fixed frame 211 is connected to the welding drive console 1, which can drive the fixed frame 211 to move up and down and left and right.

[0038] The fixed frame 211 has two rod-shaped structures at the end away from the welding drive control console 1. Each rod-shaped structure of the fixed frame 211 has a strip-shaped groove structure at each of its four corners. The movable frame 212 cooperates with the strip-shaped groove structure of the fixed frame 211.

[0039] During the movement of the fixed frame 211 and the movable frame 212, the structure of the movable frame 212 cooperating with the strip-shaped groove structure of the fixed frame 211 supports the inner side of the moving block 221, so that the moving block 221 moves from the fixed frame 211 to the movable frame 212 without displacement or swaying, and moves stably along the straight path formed between the fixed frame 211 and the movable frame 212.

[0040] The two rod-shaped structures of the fixed frame 211 are rotatably connected to threaded rods 213 on their inner sides. The movable frame 212 is threaded onto the outer surface of the threaded rods 213. Rotating the threaded rods 213 engages with the movable frame 212, which can adjust the total length between the movable frame 212 and the fixed frame 211.

[0041] In this embodiment, the threaded rod 213 can be manually controlled, or a motor that drives the threaded rod 213 to rotate can be installed on the fixed frame 211.

[0042] The toothed portions of the two gear toothed plate meshing assemblies 223 are connected to the fixed frame 211 and the movable frame 212 respectively, and the gear portions of the two gear toothed plate meshing assemblies 223 are elastically torsionally mounted on the outside of the drive shaft 222.

[0043] Two inner disks 229 are coaxially sleeved on the outside of the drive shaft 222. The gear parts of the two gear tooth plate meshing assemblies 223 are respectively rotatably sleeved on the outside of the two inner disks 229. Multiple circumferentially distributed arc-shaped blocks 2210 are fixed on the outer circumferential surface of the inner disks 229. An arc-shaped limiting groove 2211 is opened on the inner ring surface of the gear part of the gear tooth plate meshing assembly 223.

[0044] The number of arc-shaped limiting grooves 2211 is equal to the number of arc-shaped blocks 2210. Multiple arc-shaped blocks 2210 are located one-to-one inside multiple arc-shaped limiting grooves 2211. The arc angle of the arc-shaped limiting grooves 2211 is greater than the arc angle of the arc-shaped blocks 2210.

[0045] During use, when adjusting the total length between the fixed frame 211 and the movable frame 212, the corresponding two toothed plate parts move relative to each other. Since the teeth of the two toothed plate parts may misalign during the movement, when the gear part meshes with the moved toothed plate part, the arc-shaped block 2210 on the inner side of the gear part moves within the arc-shaped limiting groove 2211, allowing the gear part to compensate for the misalignment distance of the teeth of the toothed plate part by deflection. This allows the gear part to mesh with the corresponding moved toothed plate part without causing misalignment and jamming. At the same time, the arc-shaped range of the arc-shaped limiting groove 2211 limits the range of movement of the arc-shaped block 2210, preventing the gear part from rotating excessively relative to the drive shaft 222.

[0046] In this embodiment, as Figures 6-9 As shown, the tapping cleaning assembly 24 includes a tapping rod 241, a force-bending rod 242, and a drive shaft 244.

[0047] The striking rod 241 is slidably sleeved on the outside of the arc welding head 23. The striking rod 241 is elastically connected to the arc welding head 23. One end of the striking rod 241 connected to the arc welding head 23 is fixed to the force-bending rod 242. The other end of the force-bending rod 242 is bent vertically away from the arc welding head 23 and then bent vertically toward the moving block 221. A vibrating wheel 243 is provided on the side of the force-bending rod 242 that is bent vertically toward the moving block 221 and close to the arc welding head 23. Multiple evenly distributed V-shaped grooves are opened on the circumferential surface of the vibrating wheel 243. The drive shaft 244 is coaxially installed with the vibrating wheel 243 and is rotatably installed on the side of the moving block 221.

[0048] During use, when the vibrating wheel 243 rotates, the striking rod 241, under the elastic action between itself and the arc welding head 23, causes the bent rod 242 to move alternately between the outer ring surface of the vibrating wheel 243 and the V-groove, causing the striking rod 241 to sway relative to the arc welding head 23. When the striking rod 241 sways, it strikes the weld.

[0049] An air jet head 25 is installed at an angle on one side of the arc welding head 23, with the air outlet of the air jet head 25 facing the welding end of the arc welding head 23.

[0050] In this embodiment, a gas generating device, preferably a fan box or air pump, is provided outside the equipment to provide airflow into the jet head 25. When the arc welding head 23 is welding, the jet head 25 sprays airflow into the welding part. The airflow removes impurities from the welding part and reduces impurities on the inside during welding. At the same time, after the weld is welded, the airflow carries away the heat of the welding part, increasing the cooling rate of the welding part. When the striking rod 241 strikes the welding part, the airflow blows away the weld slag under the strike, improving the cleanliness of the welding part.

[0051] The drive assembly 22 also includes a drive shaft 224, a control board 225, a main sleeve shaft 226, a secondary sleeve shaft 227, and a driven shaft 228.

[0052] The drive shaft 224 is coaxially mounted with the drive shaft 222. A drive telescopic cylinder is mounted on one side of the control board 225. The drive telescopic cylinder drives the control board 225 to move relative to the moving block 221. The drive telescopic rod is connected to the moving block 221.

[0053] The drive telescopic cylinder can preferably be an electric telescopic cylinder or a hydraulic cylinder, and the drive telescopic cylinder drives the control plate 225 to move by telescopic movement.

[0054] The main sleeve prism 226 is slidably sleeved on the outside of the drive prism 224. The control plate 225 is rotatably sleeved on the outer surface of the main sleeve prism 226. The control plate 225 is rotatably sleeved on the outer surface of the auxiliary sleeve prism 227. The main sleeve prism 226 and the auxiliary sleeve prism 227 are driven by the conveyor belt 2212. The driven prism 228 is coaxially sleeved on the outer surface of the transmission shaft 244. The inner shape of the driven prism 228 matches that of the auxiliary sleeve prism 227. The transmission shaft 244 is coaxially located inside the auxiliary sleeve prism 227.

[0055] During operation, when the arc welding head 23 is welding, the control plate 225 drives the secondary sleeve shaft 227 to disengage from the driven shaft 228. At this time, the drive shaft 222 cannot drive the vibrating wheel 243 to rotate through the transmission. When the control plate 225 drives the secondary sleeve shaft 227 to engage with the driven shaft 228, the main sleeve shaft 226, driven by the drive shaft 224, drives the secondary sleeve shaft 227 to rotate through the conveyor belt 2212. The secondary sleeve shaft 227 drives the transmission shaft 244 and the vibrating wheel 243 to rotate.

[0056] A supporting bending rod 245 is installed on one side of the stressed bending rod 242. A suspended support plate 246 is provided between the supporting bending rod 245 and the stressed bending rod 242. The suspended support plate 246 is fixed to the control plate 225. One end of the suspended support plate 246 is set straight, and the other end of the suspended support plate 246 is set at an angle.

[0057] When the secondary sleeve shaft 227 disengages from the driven shaft 228, the support rod 245 is in the horizontal position of the suspended support plate 246, at which point the striking rod 241 disengages from the welding surface. When the striking rod 241 is needed to strike the welding surface, when the secondary sleeve prism 227 and the driven prism 228 are engaged, the support bent rod 245 moves to the inclined part of the suspended support plate 246, so that the stressed bent rod 242 can move to the lowest part of the V-groove.

[0058] The method for treating welded surfaces in steel structure engineering includes the following steps: S1. Fix the steel structure to be welded to both sides of the welding unit 2, and at the same time control the contact surfaces of the two steel structures to be located in the same vertical plane of the two welding units 2.

[0059] S2. The welding drive control console 1 controls two welding processing units 2 located at two adjacent welding surfaces of the steel structure.

[0060] S3. The drive component 22 first controls the arc welding head 23 to move and weld relative to the weld seam of the steel structure.

[0061] S4. After the welding of one side of the steel structure by the arc welding head 23 is completed, the arc welding head 23 is controlled to stop welding, and the drive assembly 22 controls the arc welding head 23 to reset to the beginning end of the weld.

[0062] S5. The control drive component 22 controls the hammering and cleaning component 24 to hammer the weld seam, and at the same time controls the hammering and cleaning component 24 to move again along the weld seam direction during the hammering to clean the surface of the weld seam that was previously passed through.

[0063] The working principle is as follows: The steel structure to be welded is fixed on both sides of the welding processing unit 2, and the contact surfaces of the two steel structures are controlled to be located in the same vertical plane of the two welding processing units 2. The welding drive console 1 controls the two welding processing units 2 to be located at two adjacent welding surfaces of the steel structure. The welding drive console 1 controls the welding end of the arc welding head 23 to contact the part to be welded through the frame component 21, and starts the arc welding head 23 to weld the steel structure. At the same time, the drive component 22 controls the arc welding head 23 to move and weld relative to the corresponding weld seam of the steel structure. After the arc welding head 23 finishes welding one side of the steel structure, the arc welding head 23 stops to continue welding. The drive component 22 controls the arc welding head 23 to reset to the beginning end of the weld seam, and controls the driving component 22 to control the hammering and cleaning component 24 to hammer the weld seam. At the same time, the hammering and cleaning component 24 moves again along the weld seam direction during the hammering to clean the surface of the weld seam that was passed through the previous path.

[0064] The above are all preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Therefore, all equivalent changes made in accordance with the structure, shape and principle of the present invention should be covered within the scope of protection of the present invention.
