Description

Technical Field

[0001] The present invention relates to the technical field of steel cage welding, and particularly to a building steel cage welding device. Background Art

[0002] A building steel cage welding device is a professional equipment for welding steel cages in construction projects. The steel cage is mainly composed of main reinforcement bars, stirrups and other steel bars. This device can weld these steel bars into an integral cage-like structure according to the design requirements, and is an indispensable equipment in the construction process of building foundations (such as pile foundations).

[0003] The types of building steel cage welding devices are divided into manual welding devices, semi-automatic welding devices and fully automatic welding devices. Among them, the fully automatic steel bar welding machine is a fully automatic welding equipment. When the fully automatic steel bar welding machine is working, first, place the main reinforcement bars on the rack of the main reinforcement bar feeding system, and through the conveying device, arrange the main reinforcement bars in sequence and fix them at the welding position; then install the spiral reinforcement bars on the rack of the spiral reinforcement bar feeding system, and the steel bar feeding device unfolds and conveys the spiral reinforcement bars to the position where they contact the main reinforcement bars; finally, start the control system, and the welding system starts to work. The welding electrodes rotate driven by the motor, and at the same time, the steel cage slowly rotates driven by the transmission system. The welding electrodes contact the main reinforcement bars and the spiral reinforcement bars. Under the set welding parameters (such as current, time, etc.), the steel bars are locally melted by resistance heat to form welding spots, and the spiral reinforcement bars are welded to the main reinforcement bars in sequence to form the spiral stirrup structure of the steel cage.

[0004] However, during the use of the welding electrodes, they will gradually wear due to long-term contact and friction with the steel bars. After the electrode columns are worn, the contact area with the steel bars increases, and the current density decreases, resulting in insufficient heat obtained at the welding area, unable to fully melt and fuse the steel bars, making the weld surface uneven and of different widths, and defects such as undercut and pores appear, affecting the forming quality of the weld. This leads to the need for workers to regularly inspect the welds of the welded steel cages, to repair the unqualified welding spots, and to adjust the welding time in time after finding weld defects to ensure the subsequent welding strength, resulting in a slowdown in the overall welding speed and affecting the production efficiency of the steel cages. Therefore, we propose a building steel cage welding device. Summary of the Invention

Detailed implementation manners

[0019] 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. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0020] Embodiment 1 Please refer to Figures 1 to 12 , the present invention provides a technical solution: a building steel cage welding device, including a frame 1, a main reinforcement feeding system 2 and a spiral reinforcement feeding system 3. The main reinforcement feeding system 2 and the spiral reinforcement feeding system 3 are respectively installed on the surface of the frame 1. The main reinforcement feeding system 2 and the spiral reinforcement feeding system 3 are both existing structures of the steel cage welding device. The main reinforcement feeding system 2 is used to place the main reinforcement and pull the main reinforcement to move in the horizontal direction; it further includes a fixing frame 4, which is installed above the frame 1 and is located between the main reinforcement feeding system 2 and the spiral reinforcement feeding system 3; a rotating frame 5, which is connected to the spiral reinforcement feeding system 3, and the spiral reinforcement feeding system 3 drives the rotating frame 5 to rotate regularly; a spiral reinforcement conveying mechanism 6, which is respectively connected to the fixing frame 4 and the rotating frame 5, and the rotating frame 5 drives the spiral reinforcement conveying mechanism 6 to rotate regularly. The rotating spiral reinforcement conveying mechanism 6 conveys the spiral reinforcement to be welded onto the main reinforcement; a welding mechanism 7, which is located outside the rotating frame 5, and the welding mechanism 7 welds the spiral reinforcement onto the surface of the main reinforcement; an inspection mechanism 8, which is located outside the rotating frame 5, and the inspection mechanism 8 inspects the welding joint of the spiral reinforcement and the main reinforcement and controls the welding time of the welding mechanism 7 or replaces the welding electrode of the welding mechanism 7 according to the inspection result.

[0021] During use, first, place the main reinforcement on the rack of the main reinforcement feeding system 2, and use the conveying device of the main reinforcement feeding system 2 to arrange and fix the main reinforcement at the welding position in sequence. Then install the spiral reinforcement in the spiral reinforcement conveying mechanism 6, and use the spiral reinforcement conveying mechanism 6 to unfold and convey the spiral reinforcement to the position in contact with the main reinforcement. Weld the spiral reinforcement and the main reinforcement through the welding mechanism 7. The spiral reinforcement feeding system 3 drives the rotating frame 5 to rotate by a preset angle, so that the spiral reinforcement contacts the adjacent main reinforcement. Detect the quality of the weld seam after the previous welding through the inspection mechanism 8, and adjust the welding time of the welding mechanism 7 or replace the welding electrode of the welding mechanism 7 during subsequent welding according to the weld seam quality detection result, so as to avoid the welding electrode being gradually worn due to long-term contact and friction with the steel bar during use and affecting the weld seam forming quality. And through the self-detection of the inspection mechanism 8, the workload of the staff is reduced, the welding steps of the steel cage are simplified, and the welding quality and production efficiency of the steel cage are improved. After the inspection mechanism 8 detects, the welding mechanism 7 continues to weld the spiral reinforcement and the main reinforcement, and then repeat the above operations until the steel cage is welded.

[0022] The stirrup conveying mechanism 6 includes a stirrup rack 60 rotatably connected to the fixed frame 4. A placing groove 61 is formed on the surface of the stirrup rack 60. A plurality of bolts 62 are installed on the surface of the stirrup rack 60, and the bolts 62 are inserted into the placing groove 61. A guiding frame 63 is provided between the stirrup rack 60 and the rotating frame 5, and the guiding frame 63 is fixedly connected to the rotating frame 5.

[0023] When the staff places the stirrups, first place the coiled stirrup coil on the surface of the stirrup rack 60, and insert the shell of the stirrup coil into the placing groove 61. The staff uses tools to turn the bolts 62, so that the plurality of bolts 62 jointly press the surface of the stirrup coil to cooperate to fix the stirrup coil. Pull out the stirrups on the surface of the stirrup coil and pass them through the guiding frame 63. The guiding frame 63 is spiral to facilitate the unfolding of the stirrups. After the stirrups pass through the guiding frame 63, they are pressed outside the main bars to cooperate with the welding mechanism 7 to weld the stirrups and the main bars.

[0024] The welding mechanism 7 includes a pressing block 70 located inside the rotating frame 5. A limiting rod 71 is fixedly connected to the outside of the pressing block 70. The limiting rod 71 penetrates the rotating frame 5 and is slidably connected to the inner wall of the rotating frame 5. A first compression spring 72 is fixedly connected to the outside of the limiting rod 71, and the first compression spring 72 is fixedly connected to the surface of the rotating frame 5. Welding grooves 73 are respectively formed on both sides of the bottom end of the pressing block 70. A plurality of conductive seats 74 are arranged in the welding grooves 73, and welding electrodes are placed in the conductive seats 74. An adjusting member 75 for adjusting the positions of the plurality of conductive seats 74 is arranged in the welding grooves 73. An energy supply member 76 for supplying power to the conductive seats 74 is arranged on the surface of the pressing block 70. A control member 77 for controlling the contact time of the welding electrodes with the stirrups is arranged outside the energy supply member 76.

[0025] In this device, the adjusting member 75, the energy supply member 76 and the control member 77 are all provided in two groups to cooperate in welding both sides of the stirrups.

[0026] Before use, the staff installs a plurality of conductive seats 74 fixed with welding electrodes in the adjusting member 75. When the stirrup feeding system 3 drives the rotating frame 5 to rotate, the rotating frame 5 drives the pressing block 70 to rotate. When the pressing block 70 rotates, it presses the stirrups so that the stirrups are attached to the surface of the main bars. Power is supplied to the conductive seats 74 through the energy supply member 76, so that the two welding electrodes located on both sides of the stirrups are powered on and heated. The resistance heat locally melts the steel bars and forms welding spots.

[0027] And according to the detection results of the calibration mechanism 8, if the surface of the weld is uneven, the width is different, and there are defects such as undercut and pores, the calibration mechanism 8 generates a log alarm to remind the staff to repair weld at this place. At the same time, the calibration mechanism 8 sends a signal to the control member 77, and the control member 77 increases the contact time of the welding electrodes with the steel bars by one unit time. The length of this unit time is set in advance by the staff; If, after a single adjustment is completed, the weld condition detected by the subsequent verification mechanism 8 improves but still has defects, the verification mechanism 8 generates a log alarm to remind the staff to perform repair welding at this location, and continues to send a signal to the control member 77. The control member 77 increases the contact time between the welding electrode and the steel bar by one unit of time until the weld detected by the verification mechanism 8 is qualified.

[0028] If the weld does not improve after a single adjustment by the control mechanism, the verification mechanism 8 generates a log alarm to remind the staff to perform repair welding at this location, and sends a signal to the adjusting member 75. The adjusting member 75 drives a plurality of conductive seats 74 to rotate, so that the unused welding electrodes are rotated to the welding stations.

[0029] The adjusting member 75 includes an insulating rod 78 fixedly connected to the conductive seat 74. A rotating disk 79 is provided in the welding groove 73. Threads 710 are provided on the outer surface of the insulating rod 78. The insulating rod 78 is threadedly connected to the inner wall of the rotating disk 79 by the threads 710. A rotating shaft 711 is fixedly connected to the center of the rotating disk 79. The rotating shaft 711 is rotatably connected to the inner wall of the pressing block 70. A rotating motor 712 is fixedly connected to one end of the rotating shaft 711 away from the rotating disk 79. The rotating motor 712 is installed on the surface of the pressing block 70.

[0030] When the adjusting member 75 works, the rotating motor 712 drives the rotating shaft 711 to rotate. The rotating shaft 711 drives the rotating disk 79 to rotate. The rotating disk 79 drives the insulating rod 78 to rotate, so that the unused welding electrodes replace the used welding electrodes, avoiding the over - wear of the welding electrodes and affecting the use of the steel cage welding.

[0031] The energy supply member 76 includes a conductive rod 713 slidably connected to the inner wall of the insulating rod 78. The conductive rod 713 penetrates through the insulating rod 78 and is fixedly connected to the conductive seat 74. A support frame 714 is fixedly connected to the bottom of the pressing block 70. An electrode rod 715 is slidably connected to the inner wall of the support frame 714. One end of the electrode rod 715 is connected to a power supply 716 through a wire. The power supply 716 is installed outside the support frame 714.

[0032] When the energy supply member 76 is in use, the wire connected to the electrode rod 715 is coiled inside the insulating rod 78. The power supply 716 supplies power to the electrode rod 715 through the wire. When the welding electrode heats the steel bar, the control member 77 makes the electrode rod 715 slide on the inner wall of the support frame 714 and squeeze the conductive rod 713. The conductive rod 713 pushes the conductive seat 74. The conductive seat 74 drives the welding electrode to squeeze the contact position between the spiral stirrup and the main bar. The electrode supplies power to the wire, and the wire supplies power to the electrode rod 715. The electrode rod 715 is made of a conductive material, so that the current is transmitted to the welding electrode through the conductive rod 713 and the conductive seat 74. The welding electrode is energized and heated, and the resistance heat melts the steel bar locally to form a welding point.

[0033] The control member 77 includes a piston plate 717 fixedly connected to the outside of the electrode rod 715. The end of the support frame 714 is communicated with a Y-shaped air pipe 718. An air pump one 719 and an air pump two 720 are respectively installed on the surface of the pressing block 70. The air pump one 719 and the air pump two 720 are respectively communicated with the two air inlet ends of the Y-shaped air pipe 718. A reset member 721 for pushing the conductive rod 713 to reset is arranged outside the conductive rod 713.

[0034] During use, the air pump one 719 is a conventional working air pump, and the working duration of the air pump one 719 is a fixed duration. The working duration of the air pump two 720 is controlled by the calibration mechanism 8. When the calibration mechanism 8 detects poor weld quality, the calibration mechanism 8 sends a signal to the air pump two 720, so that the air pump two 720 takes over the air pump one 719 after the air pump one 719 works for a fixed duration and continues to output gas for one unit time, ensuring that the contact time between the welding electrode and the steel bar increases by one unit time; if it receives a signal sent by the calibration mechanism 8 again, the air pump two 720 continues to output gas for two unit times after the air pump one 719 finishes working, so that the contact time between the welding electrode and the steel bar increases by one unit time; if the calibration mechanism 8 does not send a signal in the next cycle, the air pump two 720 works for two unit times during the next welding operation; until it receives a signal sent by the calibration mechanism 8 again, it continues to increase the working time; if the rotating motor 712 is working, the working time of the air pump two 720 is reset to zero.

[0035] The gas output by the air pump one 719 or the air pump two 720 enters the inner wall of the insulating rod 78 through the Y-shaped air pipe 718, increasing the air pressure inside the inner wall of the insulating rod 78, thereby pushing the piston plate 717 to drive the electrode rod 715 to move. Since the wire is coiled inside the insulating rod 78, the wire does not limit the movement of the electrode rod 715. The movement of the electrode rod 715 causes it to contact and squeeze the conductive rod 713, so that the conductive rod 713 pushes the conductive seat 74 to move, and the conductive seat 74 drives the welding electrode to squeeze the contact position between the stirrup and the main reinforcement. When both the air pump one 719 and the air pump two 720 stop working, the reset member 721 drives the conductive rod 713 to reset. While the conductive rod 713 drives the welding electrode to reset, it squeezes the electrode rod 715 to reset.

[0036] The reset member 721 includes an insulating plate 722 fixedly connected to the outside of the conductive rod 713. A limiting groove 723 slidably connected to the insulating plate 722 is formed on the inner wall of the insulating rod 78. An insulating plate 722 is fixedly connected to the outside of the insulating plate 722, and a reset spring 724 is fixedly connected to the inner wall of the limiting groove 723.

[0037] When the gas output by air pump 1 (719) or air pump 2 (720) enters the inner wall of the insulating rod 78 through the Y-shaped gas pipeline 718, the conductive rod 713 moves, driving the insulating plate 722 to slide on the inner wall of the limiting groove 723. The insulating plate 722 presses the return spring 724. After both air pump 1 (719) and air pump 2 (720) stop working, the compressed return spring 724 pushes the insulating plate 722 to reset, and the insulating plate 722 drives the conductive rod 713 to reset.

[0038] The calibration mechanism 8 includes a mounting frame 80 fixedly connected to the rotating frame 5. Two industrial cameras 81 are installed inside the mounting frame 80, and the two industrial cameras 81 are located on both sides of the mounting frame 80 respectively.

[0039] The industrial camera 81 is a camera specially designed for industrial applications in the prior art. Compared with ordinary civilian cameras, it has characteristics such as higher image stability, high transmission ability, and high anti-interference ability. Its main function is to convert optical images into digital signals so that the computer can process and analyze them.

[0040] After the stirrup feeding system 3 drives the rotating frame 5, the two industrial cameras 81 take pictures of the welds on the stirrups twice respectively, and send the taken pictures to the computer. The computer compares the pictures with the weld pictures in the picture library to judge the weld quality, and the computer sends a working signal to air pump 2 (720) or the rotating motor 712 according to the comparison result.

[0041] Embodiment 2 In this second embodiment, other structures remain unchanged. Different from the first embodiment, a weld surface treatment mechanism 9 is provided between the mounting frame 80 and the pressing block 70. The weld surface treatment mechanism 9 includes a plurality of impellers 90 located between the mounting frame 80 and the pressing block 70. The impellers 90 are rotatably connected to the rotating frame 5. A plurality of racks 91 are installed on the surface of the stirrup feeding system 3, and a transmission member 92 for driving the plurality of impellers 90 to rotate when the rotating frame 5 rotates is provided on the inner wall of the rotating frame 5.

[0042] In this embodiment, the position of the industrial camera 81 is separated from the working position of the welding electrode by multiple main bars, avoiding the welding slag generated during steel bar welding from flying onto the surface of the industrial camera 81 lens. When the rotating frame 5 rotates, the weld surface treatment mechanism 9 processes the just-welded weld to avoid the welding slag adhering to the weld surface and affecting the shooting effect of the industrial camera 81.

[0043] When the weld surface treatment mechanism 9 works, the rotating frame 5 drives the transmission member 92 to rotate. The transmission member 92 rotates under the action of the rack 91, and the transmission member 92 drives the impellers 90 to rotate. The airflow generated by the rotation of the impellers 90 flows towards the weld position to cooperate with cleaning the welding slag adhering to the weld surface and improving the shooting effect of the industrial camera 81.

[0044] The transmission member 92 includes a driving gear 93 rotatably connected to the inner wall of the rotating frame 5. The driving gear 93 meshes with the rack 91. A plurality of driven gears 94 are rotatably connected to the inner wall of the rotating frame 5. A toothed ring 95 is meshed inside the plurality of driven gears 94. The shaft rod of one of the driven gears 94 is fixedly connected to the shaft rod of the driving gear 93. The shaft rods of the two impellers 90 respectively penetrate through the rotating frame 5 and are fixedly connected to the shaft rods of the corresponding driven gears 94.

[0045] When the rotating frame 5 rotates, it drives the driving gear 93 to rotate around the rack 91. When the driving gear 93 meshes with the rack 91, the rotating frame 5 drives the driving gear 93 to perform epicyclic motion, which will cause the driving gear 93 to rotate self - axially. The driving gear 93 rotates self - axially to drive the driven gear 94 fixedly connected to it to rotate coaxially. The driven gear 94 drives the remaining plurality of driven gears 94 to rotate synchronously through the toothed ring 95. When the driven gear 94 rotates, it drives the impeller 90 fixedly connected to it to rotate synchronously. And because the number of teeth of the rack 91 is much larger than the number of teeth of the driving gear 93, when the rotating frame 5 drives the driving gear 93 to perform epicyclic motion by a fixed angle, the driving gear 93 rolls on the surface of the rack 91, causing the driving gear 93 to rotate self - axially for multiple turns. Furthermore, when the rotating frame 5 rotates by a fixed angle, the impeller 90 will rotate synchronously for multiple turns, thereby generating an air flow to cooperate with the cleaning of the steel bar weld.

[0046] Embodiment Three Please refer to Figure 13 , in this Embodiment Three, other structures remain unchanged. Different from Embodiment One, detection members 82 are respectively installed on both sides of the inner wall of the mounting frame 80. The detection members 82 are used to detect whether there are pore defects at the welding position of the spiral bar and the main bar. The detection member 82 includes a probe rod 83 slidably connected to the inner wall of the mounting frame 80. One end of the probe rod 83 close to the mounting frame 80 is fixedly connected with a limiting plate 84. The limiting plate 84 is slidably connected to the inner wall of the mounting frame 80. A connecting rod 85 is fixedly connected to the outside of the limiting plate 84. A second compression spring 86 is sleeved outside the connecting rod 85. Both ends of the second compression spring 86 are fixedly connected with the limiting plate 84 and the inner wall of the mounting frame 80 respectively. One end of the connecting rod 85 away from the limiting plate 84 is fixedly connected with a switch 87. The switch 87 is connected to the controller 88. The controller 88 is connected to the second air pump 720 and the rotation motor 712.

[0047] The switch 87 is a normally open switch. A normally open switch is an electrical switch. In its normal state (when no external force is applied), its contacts are open, the circuit is in an open state, and current cannot pass through.

[0048] When the welded stirrups and main bars pass by the inner side of the mounting frame 80, the probe rod 83 located on the inner side of the mounting frame 80 is pressed by the second compression spring 86 to fit the surface of the welding position of the stirrups and main bars. If there are porosity defects at the weld, the second compression spring 86 will push the probe rod 83 to move outwards. The probe rod 83 pulls the limit plate 84 to slide on the inner wall of the mounting frame 80. The limit plate 84 pulls the connecting rod 85, and the connecting rod 85 pulls the switch 87, causing the switch 87 to close, so that the circuit where the controller 88 is located is connected. Thus, the controller 88 operates and sends a working signal to the second air pump 720 to cooperate with adjusting the contact time between the welding electrode and the steel bars during the subsequent welding of the stirrups and main bars.

[0049] In this embodiment, the mechanical contact method of the probe rod 83 is used to judge whether there are porosity defects at the weld. Compared with the judgment method of taking and uploading the weld photos of the industrial camera 81 to the computer and comparing them with the photo library, although the detected defect type is single, the judgment by mechanical means is more stable. The shooting effect of the industrial camera 81 is easily affected by light. Too strong or too weak light, uneven light distribution, etc. may all lead to a decline in image quality and affect the accuracy of the detection result. The contact detection of the probe rod 83 does not depend on external light. Under any light conditions, it can stably detect, is less interfered by environmental factors. Moreover, when the steel cage is welded, the temperature is high and the welding slag is easy to splash. The working environment of the industrial camera 81 is poor and its service life is easily affected.
