Technical Field

[0001] The present invention relates to the technical field of steel bar welding, and particularly to a steel bar welding device for construction engineering construction sites. Background Art

[0002] Steel bar welding technology is an important process in construction engineering and civil engineering, and plays a key role especially in the construction of concrete structures. Steel bars are steel strips, which are indispensable materials in construction. They can mainly be used as the framework of buildings to improve the structural strength and stability of buildings. In order to improve the support stability of steel bars, generally two sections of steel bars need to be welded during use.

[0003] Patent No. CN219484718U discloses a steel bar welding device for construction engineering construction sites, including a support assembly, a steel bar fixing and docking assembly, and a welding assembly. Among them, the support assembly includes a welding table, a horizontal guide rail frame, a moving slide, and a slide rail; the steel bar fixing and docking assembly includes a slide plate, a clamping seat, a partition board, an adaptive fixing ring, a flexible sleeve, a piston rod, and a compression spring; the welding assembly includes a welding torch fixing plate, a welding torch, a multi-head connection board, and a welding head. This patent can quickly fix and weld multiple steel bars, reduce the time for installing and disassembling steel bars, and through the combined use of the steel bar fixing and docking assembly and the welding assembly, it can not only weld multiple steel bars simultaneously, but also weld a single steel bar, greatly improving the applicability of the device, providing multiple welding options, enriching the functions of the welding device, and being adjustable in multiple parts with high operability. However, when the existing steel bar welding device for construction engineering construction sites is actually used, there are still many drawbacks. For example, rust on the surface of steel bars will cause defects such as pores and slag inclusions during the welding process, seriously affecting the density of welding. Removing rust can reduce the occurrence of these defects and improve the overall quality of the weld. Therefore, it is very necessary to design a steel bar welding device for construction engineering construction sites. Summary of the Invention

[0004] The purpose of the present invention is to provide a steel bar welding device for construction engineering construction sites to solve the problems raised in the above background art.

[0005] To solve the above technical problems, the present invention provides the following technical solution: A steel bar welding device for a construction engineering construction site, including a bottom plate, the front and rear ends of the upper surface of the bottom plate are respectively fixedly connected with support plates, the upper surface of the bottom plate is provided with a rust removal mechanism, two fixed ear plates are fixedly connected to the upper surface of the bottom plate, a main shaft is rotatably connected between the two fixed ear plates, two belts are arranged on the outer surface of the main shaft, a welding slag protection and cleaning mechanism is fixedly connected to the middle of the upper surface of the bottom plate, a rust removal mechanism is fixedly connected to the left side of the bottom plate, a threaded steel is arranged on the upper surface of the support plate, the rust removal mechanism includes a bracket, the bracket is fixedly connected to the upper surface of the bottom plate, a threaded rod is rotatably connected inside the bracket, a turntable is fixedly connected to one end of the threaded rod close to the top of the bracket, a drill frame is rotatably connected to the outer surface of the threaded rod, a drill bit is arranged at one end of the drill frame away from the threaded rod, a toothed plate is fixedly connected to the bottom surface of the drill frame, the outer surface of the toothed plate is drivingly connected with a bidirectional screw rod, the outer surface of the bidirectional screw rod is rotatably connected with two inverted ear plates, the two ends of the bidirectional screw rod are respectively rotatably connected with upright ear plates, a rust removal frame is fixedly connected to the top surface of each inverted ear plate, a first rust removal plate is movably connected to the inner wall of the rust removal frame, a fixing plate is fixedly connected to the outer surface of the first rust removal plate, a second rust removal plate is movably connected to the bottom surface of the fixing plate, a sliding rod is fixedly connected to one end of the rust removal frame away from the inverted ear plate, a moving groove is formed inside the bracket, and the moving groove is adapted to the drill frame, a first rust removal spring is arranged on the outer surface of the first rust removal plate, and the two ends of the first rust removal spring are respectively fixedly connected with the first rust removal plate and the first rust removal plate, a second rust removal spring is arranged on the bottom surface of the fixing plate, and the two ends of the second rust removal spring are respectively fixedly connected with the fixing plate and the second rust removal plate. When the threaded steel rotates, the turntable is rotated to make the toothed plate on the drill frame move upward, and at the same time drive the inverted ear plates at both ends of the bidirectional screw rod meshing with the toothed plate to approach each other, and finally make the rust removal frames on the inverted ear plates approach each other in the moving groove. At this time, the inner wall of the first rust removal plate closely adheres to the welding surface of the threaded steel to be welded, and the second rust removal plate closely adheres to the threaded surface of the threaded steel under the action of the second rust removal spring. Under the action of the rotation of the threaded steel, the rust on the surface and inside the thread of the threaded steel can be removed. Rust will cause defects such as pores and slag inclusions during the welding process, seriously affecting the density of welding. This process can remove the rust at the welding point, ensure good contact between the welding metals, and removing rust can reduce the occurrence of these defects and improve the welding quality.

[0006] According to the above technical solution, the rotary welding mechanism includes a support plate fixedly connected to the upper surface of the bottom plate. At both ends of the support plate, semi-threaded columns are rotatably connected. A second gear is fixedly connected to the outer surface of each semi-threaded column. A sleeve is rotatably connected to the inner wall of the support plate. A first gear is fixedly connected to the outer surface of the end of the sleeve close to the support plate. A clamping column is slidably connected to the other end of the sleeve. A push plate is slidably connected to the outside of the sleeve. A sliding column is fixedly connected to the top side of the push plate. The end of the sliding column away from the push plate is slidably connected to a push ring. A clamping block is fixedly connected to the outer surface of the push ring. A sliding block is fixedly connected to the inner wall of the push ring. One end of the clamping column close to the inner wall of the sleeve is fixedly connected to a pressing plate. A clamping groove is formed at the end of the clamping column away from the pressing plate, and the clamping groove is adapted to the clamping block. The first gear and the second gear are meshed with each other. A sliding groove is formed in the front outer surface of the sleeve, and the sliding groove is adapted to the sliding block. A sliding track is formed inside the push ring, and the sliding track is adapted to the sliding column. A rotating groove is formed in the outer surface of the sleeve, and the rotating groove is adapted to the support plate. A moving groove is formed in the outer surface of the sleeve in front of the rotating groove, and the moving groove is adapted to the push plate. A boosting spring is arranged on the outer surface of the pressing plate, and both ends of the boosting spring are fixedly connected to the pressing plate and the sleeve respectively. Both ends of the push plate are rotatably connected to the semi-threaded columns. The threaded steel to be welded is inserted into the sleeves at the left and right ends, and the welding points are aligned. Then, the external motor is started to rotate the main shaft. The main shaft drives the second gear on the semi-threaded column to rotate through the transmission belt. At the same time, the push ring meshed with the second gear moves in the opposite direction following the rotation of the second gear, so that the sleeve connected to the first gear moves synchronously. The sleeve drives the push ring to move synchronously on the sliding column through the sliding block adapted to the sliding groove. When the semi-threaded column rotates, the push plate moves smoothly along the thread direction, so that the sliding column on the push plate pushes the push ring to move synchronously. Finally, the clamping block enters the clamping groove, and the clamping block presses the clamping column so that the pressing plates on the clamping column approach each other to clamp the threaded steel. At this time, the threaded steel can rotate while being clamped, so that the drill bit welds the welded part of the threaded steel evenly. This process realizes the firm connection between the threaded steels, ensures the weld strength of the welding, and improves the product quality at the same time.

[0007] According to the above technical solution, the welding slag protection and cleaning mechanism includes a collection box, which is fixedly connected to the upper surface of the center of the bottom plate, and the front side of the collection box is slidably connected to a concentration box, a vibration spring is provided on the upper surface of the collection box, and the two ends of the vibration spring are respectively fixedly connected to the collection box and the protective cover, the upper surface of the protective cover is fixedly connected to an extrusion rod, the upper surface of the extrusion rod is fitted with a cam, and the axis of the cam is fixedly connected with a connecting shaft, the inner wall of the collection box is fixedly connected with a first inclined plate, and the right side of the first inclined plate is fitted with a second inclined plate, the inside of the collection box is fixedly connected with a pillar, the upper surface of the pillar is fixedly connected with a placement rack, the upper surface of the placement rack is fitted with threaded steel, and both ends of the connecting shaft are fixedly connected with semi-threaded columns, and the upper surface of the collection box is provided with a displacement groove, and the displacement groove is The sliding rods are adapted to each other, and a transmission belt is provided on the outer surface of the semi-threaded column, and the two ends of the transmission belt are respectively connected to the semi-threaded column and the main shaft. When welding, welding slag is easy to splash everywhere, and the splashed welding slag is restricted in its moving trajectory by the protective cover. After the welding slag hits the inner wall of the protective cover, some of it will fall into the collection box along the inner wall of the protective cover, and some of it will adhere to the inner wall of the collection box. The rotating semi-threaded column drives the cam on the connecting shaft to frequently squeeze the extrusion rod on the protective cover, and at the same time, the protective cover vibrates under the action of the vibration spring, so that the welding slag attached to the inner wall of the protective cover enters the collection box, and then falls into the collection box through the inclined surface of the first inclined plate and the second inclined plate. This process can ensure that the welding slag does not splash everywhere. If the welding slag is not cleaned up in time at the welding site, collecting the welding slag can keep the working environment clean and prevent the welding slag from falling into the gap between parts and wearing parts.

The present invention is provided with a support plate, a sleeve, a push ring, a first gear, a second gear, a push plate, a semi-threaded column, a clamping column, a clamping block, a sliding column, a sliding block, and an extrusion plate. At this time, the threaded steel can be rotated while being clamped, so that the drill bit can weld the threaded steel welding part uniformly.

[0013] The welding slag protection and cleaning mechanism 7 includes a collection box 701, which is fixedly connected to the upper surface of the center of the bottom plate 1.

This process can ensure that the welding slag does not splash everywhere. If the welding slag is not cleaned in time at the welding site, collecting the welding slag can keep the working environment clean and prevent the welding slag from falling into the part gaps and wearing the parts.

[0014] Working principle: The threaded steel 9 to be welded is inserted through the sleeve 602 at both left and right ends to align the welding points. Subsequently, the external motor is started to rotate the main shaft 2. The main shaft 2 drives the second gear 605 on the semi-threaded column 607 to rotate through the transmission belt. At the same time, the pushing ring 603 meshing with the second gear 605 moves in the opposite direction following the rotation of the second gear 605, so that the sleeve 602 connected to the first gear 604 moves synchronously. The sleeve 602 drives the pushing ring 603 to move synchronously on the sliding column 610 through the slider 611 adapted to the chute. When the semi-threaded column 607 rotates, the pushing plate 606 moves smoothly along the thread direction, so that the sliding column 610 on the pushing plate 606 pushes the pushing ring 603 to move synchronously. Finally, the clamping block 609 enters the clamping groove, and the clamping block 609 pushes the clamping column 608 to make the pressing plates 612 on the clamping column 608 approach each other to clamp the threaded steel 9. At this time, the threaded steel 9 can rotate while being clamped, so that the drill bit 313 welds the welding part of the threaded steel 9 evenly. This process realizes the firm connection between the threaded steels 9, ensures the welding seam strength, and improves the product quality at the same time; When the ribbed steel bar 9 rotates, the turntable 303 is rotated to move the toothed plate 305 on the drill rig 304 upward. At the same time, the inverted ear plates 306 at both ends of the bidirectional screw 307 meshing with the toothed plate 305 are driven to approach each other, and finally the rust removal frames 309 on the inverted ear plates 306 approach each other in the moving grooves. At this time, the inner wall of the first rust removal plate 310 closely adheres to the welding surface of the ribbed steel bar 9 to be welded, and the second rust removal plate 312 closely adheres to the thread surface of the ribbed steel bar 9 under the action of the second rust removal spring. Under the action of the rotation of the ribbed steel bar 9, the rust on the surface and in the threads of the ribbed steel bar 9 can be removed. Rust will cause defects such as pores and slag inclusions during the welding process, seriously affecting the density of the welding. This process can remove the rust at the welding point, ensure good contact between the welding metals, remove the rust to reduce the occurrence of these defects, and improve the welding quality; The turntable 303 is rotated to move the toothed plate 305 on the drill rig 304 downward. At the same time, the inverted ear plates 306 at both ends of the bidirectional screw 307 meshing with the toothed plate 305 are driven to move away from each other. During welding, the welding slag is likely to splash everywhere. The moving trajectory of the splashing welding slag is restricted by the protective cover 706. After the welding slag hits the inner wall of the protective cover 706, some will fall into the collection box 701 along the inner wall of the protective cover 706, and some will adhere to the inner wall of the collection box 701. The semi-threaded column 607 drives the cam 704 on the coupling shaft 703 to frequently squeeze the extrusion rod 705 on the protective cover 706, and at the same time, the protective cover 706 vibrates under the action of the vibration spring, so that the welding slag adhering to the inner wall of the protective cover 706 enters the collection box 701, and then falls into the concentration box 702 under the action of the inclined surfaces of the first inclined plate 707 and the second inclined plate 708. This process can ensure that the welding slag does not splash everywhere. If the welding slag is not cleaned up in time at the welding site, collecting the welding slag can keep the working environment clean and prevent the welding slag from falling into the part gaps and wearing the parts.
