[0018] The beneficial effects of the present invention are as follows:

[0019] 1. The present invention provides a distance control component. Since the secondary steel bars are wound in the winding mechanism before welding, when the secondary steel bars are wound around the main steel bars and have not yet been welded, tension will be generated between the spiral shape and the axial direction. As a result, the secondary steel bars may separate from the welding groove of the main steel bars during the winding process, making it impossible for the welding mechanism to contact the secondary steel bars and complete the welding. Therefore, before welding, the visual sensor will first visually monitor the position between the main and secondary steel bars. If the secondary steel bars are found to be separated from the welding groove of the main steel bars, the telescopic rod 1 will drive the support block 1 to move to the bottom of the offset secondary steel bars, and then the telescopic rod 2 will extend upward to make the fitting frame contact with the secondary steel bars. Then the telescopic rod 1 moves toward the welding groove and the secondary steel bars are placed into the welding groove by resetting the telescopic rod 2.

[0020] 2. The present invention is provided with a winding mechanism. Since sparks are generated during the welding process and the winding drum is contaminated with dust and oil after long-term operation, these impurities will adhere to the secondary steel bars as they move, thereby affecting the fit between the secondary steel bars and the welding grooves on the main steel bars. Therefore, when the secondary steel bars are removed from the winding drum, they will pass through the side plates. The isolation holes on the side plates will block rust that does not belong to the secondary steel bars and sparks from previous welding.

[0021] 3. The present invention sets a pre-treatment mechanism. After the iron filings and solidified sparks on the secondary steel bars are isolated, the micro motor will also drive the rotating rod and the nylon brush to rotate, so that the nylon brush can penetrate into the gaps between the steel wires and scrape off solid impurities such as rust and dirt attached to the gaps. At the same time, the gas compressor uses compressed air to blow out the gaps between the steel wires and blow out the remaining oil stains or moisture in the gaps. BRIEF DESCRIPTION OF THE DRAWINGS

[0033] The present invention will be described in further detail below with reference to the accompanying drawings and specific embodiments. The embodiments of the present invention are provided for purposes of illustration and description and are not intended to be exhaustive or to limit the invention to the disclosed forms. Many modifications and variations will be apparent to those skilled in the art. The embodiments are chosen and described to better illustrate the principles of the invention and its practical application, and to enable those skilled in the art to understand the invention and design various embodiments with various modifications suitable for specific applications.

[0034] Example 1: Use Figures 1-10 A reinforcement cage welding device for bridge construction according to one embodiment of the present invention is described below.

[0035] like Figure 1-Figure 2 As shown, a steel cage welding device for bridge construction of the present invention includes a welding main plate 1, a support leg 2 is provided at the bottom of the welding main plate 1, a visual sensor 4 for monitoring the position of the welding point is provided on the top of the welding main plate 1, and the visual sensor 4 is fixed to the top of the welding main plate 1 through a support rod 3. A rotating unit 5 is provided on the inner wall of the welding main plate 1, and further includes:

[0036] A guide unit 6 cooperating with the rotation unit 5 and a distance control component 7 provided at one end of the guide unit 6 close to the welding main board 1;

[0037] When the present invention is working, the main steel bar 65 needs to be placed into the conductor 5710 unit first. The guide unit 6 will control the axial movement of the main steel bar 65. At the same time, the rotating unit 5 will start to rotate and wrap the secondary steel bar 583 around the main steel bar 65. Then the distance control component 7 will control the winding distance of the secondary steel bar 583, and welding will be performed when there is no deviation in the distance.

[0038] like Figure 4 As shown, the distance control assembly 7 includes a telescopic rod 1 71, the output end of the telescopic rod 1 71 is fixedly connected to a support block 1 72, a telescopic rod 2 73 is arranged inside the support block 1 72, the output end of the telescopic rod 2 73 is fixedly connected to a support block 2 74, and a fitting frame 75 is symmetrically arranged on the top of the support block 2 74;

[0039] When the visual sensor 4 detects a deviation in the welding point, the telescopic rod 1 71 and the telescopic rod 2 73 will automatically extend and retract to correct the position of the steel bar.

[0040] Since the secondary steel bars 583 are all wound in the winding mechanism 58 before welding, when the secondary steel bars 583 are wound on the main steel bars 65 and have not yet been welded, due to the spiral shape and the tension between the axial directions, the secondary steel bars 583 may be separated from the welding groove 66 of the main steel bars 65 during the winding process, so that the welding mechanism cannot contact the secondary steel bars 583 and complete the welding. Therefore, before welding, the visual sensor 4 will first visually monitor the position between the main steel bars 65 and the secondary steel bars 583. If the secondary steel bars 583 are found to be separated from the welding groove 66 of the main steel bars 65, the telescopic rod 1 71 will drive the support block 1 72 to move to the bottom of the offset secondary steel bars 583, and then the telescopic rod 2 73 will extend upward and make the fitting frame 75 contact the secondary steel bars 583. Then the telescopic rod 1 71 moves toward the welding groove 66 and the secondary steel bars 583 are placed in the welding groove 66 through the resetting of the telescopic rod 2 73.

[0041] like Figure 3 As shown, the guide unit 6 includes a disc 61, and support legs 62 are symmetrically provided at the bottom of the disc 61. A support column 63 is fixedly connected to the side of the disc 61 facing the welding main board 1, and an inner disc 64 is fixedly connected to the end of the support column 63 away from the disc 61. The inner disc 64 is provided with main steel bars 65, and welding grooves 66 are evenly provided on the main steel bars 65. Electrode 1 67 is evenly provided on the side of the inner disc 64 close to the disc 61, and the electrode 1 67 is connected to the main steel bar 65. A clamping mechanism 68 is also provided at the bottom of the disc 61.

[0042] When placing the main steel bars 65, the steel bars need to be placed one by one into the inner plate 64 and connected to the electrode 1 67 to ensure that resistance welding can be performed later;

[0043] Before welding, most of the main steel bars 65 are located inside the frame plate 55 , and one end of the main steel bar 65 is fixed by the clamping mechanism 68 .

[0044] The outer surface of the telescopic rod 71 is fixedly connected to the inner wall of the support column 63, and the outer surface of the main steel bar 65 is slidably connected to the inner wall of the inner plate 64.

[0045] like Figure 5-Figure 6 As shown, the clamping mechanism 68 includes a support plate 1 681, a servo motor 1 682 is provided at the bottom of the support plate 1 681, the output end of the servo motor 1 682 is fixedly connected to a reciprocating screw 683, the outer surface of the reciprocating screw 683 is slidably connected to a moving block 684, the top of the moving block 684 is fixedly connected to a support plate 2 685, the top of the support plate 2 685 is fixedly connected to a disc 2 686, the disc 2 686 is provided with an inner hole 687 corresponding to the position of the main steel bar 65, the inner wall of the disc 2 686 is provided with a hydraulic rod 688, and the output end of the hydraulic rod 688 is fixedly connected to a clamping plate 689 adapted to the main steel bar 65.

[0046] After one end of the main steel bar 65 enters the inner hole 687, the hydraulic rod 688 will extend and cause the clamping plate 689 to squeeze the main steel bar 65, thereby fixing the main steel bar 65 relative to the disc 2 686, so that when the rotating unit 5 works, the servo motor 1 682 drives the reciprocating screw 683 to move, thereby driving the moving block 684, the support plate 2 685, the disc 2 686 and the main steel bar 65 to move, thereby evenly winding the secondary steel bar 583 around the main steel bar 65.

[0047] The center height of disk 2 686 is the same as that of disk 1 61 , and the top of support plate 1 681 is fixedly connected to the outer surface of disk 1 61 .

[0048] The specific workflow is as follows:

[0049] During operation, one end of the main steel bar 65 is inserted into the inner hole 687, and the hydraulic rod 688 is extended to make the clamping plate 689 squeeze the main steel bar 65, so that the main steel bar 65 and the disc 2 686 are relatively fixed, so that when the rotating unit 5 works, the servo motor 1 682 drives the reciprocating screw 683 to move, thereby driving the moving block 684, the support plate 2 685, the disc 2 686 and the main steel bar 65 to move, so that the secondary steel bar 583 is evenly wound on the main steel bar 65. The visual sensor 4 will first check the main steel bar 65 and the The position between the secondary steel bars 583 is visually monitored. If the secondary steel bar 583 is found to be separated from the welding groove 66 of the main steel bar 65, the telescopic rod 1 71 will drive the support block 1 72 to move to the bottom of the offset secondary steel bar 583, and then the telescopic rod 2 73 will extend upward and make the fitting frame 75 contact with the secondary steel bar 583. Then the telescopic rod 1 71 moves toward the welding groove 66 and puts the secondary steel bar 583 into the welding groove 66 through the resetting of the telescopic rod 2 73, and then the welding of the main steel bar 65 and the secondary steel bar 583 is carried out.

[0050] Example 2: Use Figures 1-10 A reinforcement cage welding device for bridge construction according to one embodiment of the present invention is described below.

[0051] like Figure 7 As shown, a steel cage welding device for bridge construction of the present invention is based on the first embodiment, and the rotating unit 5 includes a support seat 51, the top of the support seat 51 is fixedly connected to a support frame 52, the top of the support frame 52 is fixedly connected to a servo motor 2 53, the output end of the servo motor 2 53 is fixedly connected to a rotating shaft 54, the outer surface of the rotating shaft 54 ​​is fixedly connected to a frame plate 55, and a space is provided inside the frame plate 55 for providing a main steel bar 65 for placement, and a rotating ring 56 is fixedly connected to the side of the frame plate 55 away from the rotating shaft 54, the outer surface of the rotating ring 56 is provided with a resistance welding mechanism 57, and the outer surface of the rotating ring 56 is also provided with a winding mechanism 58.

[0052] Servo motor 2 53 drives the rotating shaft 54 ​​and the frame plate 55 to rotate, thereby driving the resistance welding mechanism 57 and the winding mechanism 58 on the rotating ring 56 to rotate. The winding mechanism 58 will wind the secondary steel bar 583 around the main steel bar 65, and then the resistance welding mechanism 57 will weld the connection.

[0053] like Figure 8 As shown, the resistance welding mechanism 57 includes a fixed plate 571, the outer surface of the fixed plate 571 is fixedly connected to a welding platform 572, the outer surface of the welding platform 572 is fixedly connected to an electrical control device 579, and a limit plate 573 is further provided on the welding platform 572. The limit plate 573 is rotatably connected to a movable arm 574, and a clamping arm 575 is provided at one end of the movable arm 574. The clamping arm 575 is fixedly connected to the second electrode 756, and the second electrode 756 is connected to the electrical control device 579 via a wire 5710. The outer surface of the welding platform 572 is fixedly connected to a hydraulic device 577, which drives a telescopic rod 3 578, and the output end of the telescopic rod 3 578 is fixedly connected to the outer surface of the clamping arm 575;

[0054] When welding is required, as the overall resistance welding mechanism 57 rotates close to the welding point, the hydraulic device 577 will control the telescopic rod three 578 to extend and drive the electrode two 756 to fit the welding point. At the same time, the control device 579 will energize the electrode two 756 through the wire 5710. The main steel bar 65 is connected to the energized electrode one 67, and the secondary steel bar 583 is connected to the energized electrode two 756. A large amount of heat will be generated at the moment the two come into contact, causing the contact point to melt and then solidify again, thereby completing the welding.

[0055] A side of the fixing plate 571 away from the welding platform 572 is fixedly connected to the outer surface of the rotating ring 56 .

[0056] like Figure 9 As shown, the winding mechanism 58 includes a fixed block 581, a winding drum 582 is provided on the fixed block 581, the inner ring of the winding drum 582 is wound with secondary steel bars 583, the thickness of the secondary steel bars 583 is adapted to the welding groove 66, the outer surface of the winding drum 582 is fixedly connected to a support rod 2 584, and the end of the support rod 2 584 away from the winding drum 582 is fixedly connected to a pretreatment mechanism 585.

[0057] First, the first section of the secondary steel bar 583 is manually welded to the main steel bar 65 , and then as the overall winding mechanism 58 rotates and the clamping mechanism 68 drives the overall movement of the main steel bar 65 , the secondary steel bar 583 will be wound around the main steel bar 65 .

[0058] like Figure 10As shown, the pretreatment mechanism 585 includes a supporting circular frame 5851, and side panels 5852 are symmetrically arranged on both sides of the supporting circular frame 5851. An isolation hole 5858 that is adapted to the size of the secondary steel bar 583 is arranged in the center of the side panel 5852 to block other impurities on the secondary steel bar 583. A micro motor 5853 is also provided on the outer surface of the side panel 5852, and a rotating rod 5854 is fixedly connected to the output end of the micro motor 5853. Nylon bristles 5855 are provided on the rotating rod 5854. A support plate three 5856 is still provided on the side panel 5852, and a gas compressor 5857 is fixedly connected to the outer surface of the support plate three 5856.

[0059] Since sparks are generated during the welding process, and the winding drum will be covered with dust and oil after working for a long time, these impurities will adhere to the secondary steel bar 583 as the secondary steel bar 583 moves, thereby affecting the fit between the secondary steel bar 583 and the welding groove 66 on the main steel bar 65. Therefore, when the secondary steel bar 583 moves out of the winding drum 582, it will pass through the side plate 5852. The isolation hole 5858 on the side plate 5852 will block the rust that does not belong to the secondary steel bar 583 and the sparks splashed by the previous welding.

[0060] After the iron filings and solidified sparks on the secondary steel bar 583 are isolated, the micro motor 5853 will also drive the rotating rod 5854 and the nylon brush to rotate, so that the nylon brush can penetrate into the gaps between the steel wires and scrape off solid impurities such as rust and dirt attached to the gaps. At the same time, the gas compressor 5857 uses compressed air to blow the gaps between the steel wires to blow out the remaining oil stains or moisture in the gaps.

[0061] The outer surface of the fixed block 581 is fixedly connected to the outer surface of the rotating ring 56 , and the outer surface of the supporting circular frame 5851 is fixedly connected to one end of the second supporting rod 584 .

[0062] The specific workflow is as follows:

[0063] During winding, the first section of the secondary steel bar 583 is manually welded to the main steel bar 65. Then, as the overall winding mechanism 58 rotates and the clamping mechanism 68 drives the overall movement of the main steel bar 65, the secondary steel bar 583 will be wound around the main steel bar 65. Then, during welding, as the overall resistance welding mechanism 57 rotates close to the welding point, the hydraulic device 577 will control the telescopic rod 3 578 to extend and drive the electrode 2 756 to fit the welding point. At the same time, the control device 579 will energize the electrode 2 756 through the wire 5710. The main steel bar 65 is connected to the energized electrode 1 67, and the secondary steel bar 583 is connected to the energized electrode 2 756. , a large amount of heat is generated at the moment the two come into contact, causing the contact point to melt. During the movement of the secondary steel bar 583, it will pass through the side plate 5852. The isolation hole 5858 on the side plate 5852 will block the rust that does not belong to the secondary steel bar 583 and the sparks of the previous welding. At the same time, the micro motor 5853 will also drive the rotating rod 5854 and the nylon brush to rotate, so that the nylon brush can penetrate into the gaps between the steel wires and scrape off the solid impurities such as rust and dirt attached to the gaps. At the same time, the gas compressor 5857 uses compressed air to blow the gaps between the steel wires to blow out the remaining oil stains or moisture in the gaps.
