Description

Technical Field

[0001] This invention relates to the field of steel wire mesh processing technology for ballastless tracks, specifically to a fully automatic steel wire mesh welding machine for ballastless tracks. Background Technology

[0002] Ballastless track refers to a track structure that uses a monolithic foundation of concrete, asphalt mixture, etc., instead of loose gravel track. Also known as ballastless track, it represents the world's most advanced track technology. During the construction of ballastless track, welded steel mesh is added to the concrete to increase its strength. The load-bearing strength of the steel mesh directly affects the structural strength and stability of the track concrete.

[0003] As the core structure of high-speed railway lines, the welding quality of the steel welded mesh of ballastless track directly determines the service life of the track structure and the safety of train operation. The industry has almost stringent standards for weld strength, welding consistency, and processing efficiency, but existing technologies still face bottlenecks that cannot be overcome. The welding mode is limited and the adaptability to working conditions is poor: Most existing equipment can only perform single arc welding (MIG / TIG) or laser welding, which cannot meet the welding needs of different specifications of steel bars and different welding point conditions (flat welding, vertical welding, lap welding) of ballastless track. The problems of insufficient penetration of thick bars and easy burn-through of thin bars have existed for a long time.

[0004] Inefficient welding head replacement and insufficient positioning accuracy: Welding mode switching requires machine shutdown and manual disassembly and assembly of the welding head, which is time-consuming and inefficient. In addition, manual operation is prone to problems such as welding head coaxiality deviation and insecure locking, resulting in unstable welding pool and substandard weld strength, which cannot meet the requirement of 100% pass rate of ballastless track welds.

[0005] Pipeline residues are difficult to clean, resulting in poor welding stability: During the welding process, debris in the wire channel, slag and oxide scale in the gas channel, and dust residue in the laser channel can directly cause wire feeding jams, protective gas leaks, and laser energy loss. Current technology can only stop the machine and manually disassemble and clean it, which is not only extremely inefficient but also very easy to damage precision pipelines. Real-time cleaning cannot be achieved, and the residue problem can never be completely solved.

[0006] Multi-media transmission interference and weak attitude adaptability: The welding wire, shielding gas and laser beam channels of existing composite welding equipment are mostly distributed externally. When the welding torch performs welding at multiple angles, the pipe is prone to twisting, bending and misalignment, which leads to fluctuations in the medium supply. In particular, there are a large number of three-dimensional spatial welding points in the ballastless track steel mesh. Existing equipment simply cannot guarantee the stability of welding in all attitudes.

[0007] Low level of automation and uncontrollable human error: Existing equipment requires multiple steps of manual intervention, from welding head selection and posture adjustment to welding execution and pipeline cleaning. This not only results in low production efficiency but also makes it easy for welding quality to fluctuate due to human error, failing to meet the needs of standardized and mass production of ballastless track prefabricated components.

[0008] Therefore, we propose a fully automatic steel wire mesh welding machine for ballastless tracks. Summary of the Invention

[0019] Compared with existing technologies: This invention integrates a three-mode welding torch mechanism with a welding wire mixing inlet, a gas mixing inlet, and a high-energy laser beam mixing inlet arranged coaxially in layers from the outside to the inside of the welding torch head. Combined with a circumferentially distributed welding head drive component, a flip-type welding head replacement component, and a fully automatic welding head replacement mechanism with an L-shaped locking block and an L-shaped self-locking hole rotational self-locking structure, it achieves fully automatic and rapid switching between three welding modes: laser welding, MIG welding, and TIG welding. It also features micron-level coaxiality installation of the welding head and highly reliable mechanical locking. This invention solves the defects of existing ballastless track steel mesh welding equipment, such as single welding mode, manual replacement requiring machine stoppage, poor welding head installation accuracy leading to insufficient adaptability to working conditions, poor weld strength consistency, and inability to meet the welding needs of ballastless tracks in all scenarios. This invention utilizes a linkage drive assembly consisting of a single first motor, drive gear, and rotating gear ring within the installation mechanism.

Combined with a guide cone with a spiral block and a rotating first cleaning assembly and a linear moving second cleaning assembly adapted to the spiral groove on the outer wall of the laser beam tube, as well as an automatic sewage discharge structure with a movable valve and sewage discharge cone triggered by the cleaning stroke, this invention achieves real-time cleaning and automatic discharge of impurities from the entire path of the welding pipeline without stopping or disassembling under a single power source drive. This solves the industry problems of existing welding equipment pipeline cleaning requiring manual disassembly and stopping, low cleaning efficiency, wire feeding jamming caused by pipeline residue, unstable media transmission, and cross-contamination during multi-mode switching. This invention integrates a multi-medium transmission pipeline into a layered coaxial integrated pipeline assembly, consisting of a laser beam tube, a gas tube, an outer casing tube, and a welding wire channel arranged sequentially from the inside out. This multi-medium transmission pipeline is fully integrated into the fixed tube of the welding head replacement mechanism. Combined with the centralized input port docking structure of the installation mechanism, this invention achieves independent isolation and stable coaxial transmission of the three major welding media: welding wire, shielding gas, and laser beam. This solves the technical bottlenecks of existing composite welding equipment, such as dispersed external pipelines, easy pipe twisting and bending during welding torch posture adjustment, medium supply fluctuations caused by multi-medium transmission interference, and poor stability of welding at all angles. This invention uses a robotic arm mechanism and an angle adjustment mechanism as the core of execution, and integrates the welding head replacement mechanism, welding torch mechanism, pipeline and linkage mechanism, and cleaning components into a complete system. It realizes closed-loop collaborative control of the entire process, including automatic selection and installation of welding heads, automatic cleaning of pipelines, automatic adjustment of welding torch posture, automatic execution of the welding process, and automatic disassembly and replacement of welding heads. This solves the defects of existing ballastless track welding equipment, such as many manual intervention links, uncontrollable human error, long waiting time for process connection, and inability to achieve large-scale standardized continuous welding production.

[0023] In practical use, those skilled in the art will place the processing platform 1 on a level surface, check the platform's flatness, place the steel mesh to be welded on the surface of the processing platform 1, and clamp the steel mesh from all sides using the platform's built-in pneumatic clamps to ensure that the steel mesh is free from warping or displacement. The external gas pipe at the left end of the angle adjustment mechanism 4 will be connected to the input port 512 of the first mounting plate 511 of the installation mechanism 5. The central fiber optic channel will be connected to the central hole of the input port 512. The welding wire external pipe 813 will be connected to the welding wire pump group. The appropriate welding wire will be selected according to the welding requirements. The robotic arm mechanism 3 will be activated, and the control system will drive the robotic arm to move the angle adjustment mechanism 4 above the processing platform 1. The angle adjustment mechanism 4 will then be activated, and the installation mechanism 5, welding head replacement mechanism 6, and welding torch mechanism 7 will be adjusted. The robot arm is positioned by scanning the weld seam of the welded wire mesh using a vision sensor to ensure the center of the welding torch is aligned with the center of the weld seam. Based on the welding process requirements of the welded wire mesh, the control system issues a command to activate the welding head drive assembly 62, moving the required first welding head 641. Simultaneously, the welding head replacement assembly 63 causes the arc rod 635 to rotate the first welding head 641, connecting it to the welding torch head 711. At this point, the locking block 643 slides into the left end of the self-locking hole 718. The self-locking assembly 72 is then activated, rotating the welding torch head 711 and inserting the locking block 643 into the self-locking hole 718. Continuous rotation causes the arc rod 635 to disengage from the clamping seat 645, and the welding head drive assembly is activated again. The drive assembly 62 and welding head replacement assembly 63 are reset to their initial positions. The external gas valve and welding wire pump are opened to test the shielding gas flow rate and welding wire delivery speed, ensuring stable media transmission. The linkage drive assembly 52 is activated, causing the second lead screw 831 to drive the first cleaning assembly 91 to move and rotate. This allows the first cleaning assembly 91 to remove residual impurities and oxide scale from the inner wall of the gas pipe 814. Simultaneously, the third lead screw 841 drives the second cleaning assembly 92 to clean the inner walls of the outer casing 811 and the welding wire pipe 812. During cleaning, the second cleaning ring 921 presses the inclined block of the movable valve 817, opening the valve. Impurities are discharged through the drain trough 819 and the slag discharge valve 614. Exhausting from the fixed tube 611, if a laser welding head is selected: The external laser is activated, and the laser beam is focused onto the surface of the welded wire mesh through the laser beam tube 821, the high-energy laser beam mixing inlet 716 of the welding torch head 711, and the mixing inlet 642 of the first welding head 641. Simultaneously, helium gas is activated, passing through the gas tube 814, the gas mixing inlet 715, and then through the mixing inlet 642, forming a gas curtain that envelops the molten pool. The robotic arm mechanism 3, in conjunction with the angle adjustment mechanism 4, drives the welding torch head 711 to move along the weld path. The laser beam melts the welded wire mesh to form a molten pool, completing the self-fusion welding. During the process, the weld offset is monitored in real time by a visual sensor, and the angle adjustment mechanism 4 dynamically corrects the welding torch posture.If a MIG welding head is selected, the welding wire pump assembly is started. The welding wire is delivered through the welding wire outer tube 813, outer sheath 811, welding wire tube 812, and welding torch head 711, and then through the mixing inlet 714 to the contact nozzle of the MIG welding head. Argon and helium gases are then introduced and ejected through the mixing inlet 642. The contact nozzle is connected to an external power source. When the welding wire contacts the steel mesh, an arc is ignited, forming an arc pool. The robotic arm moves the welding torch head 711 along the weld seam, and the welding wire continuously melts and fills the molten pool until the welding is completed. If a TIG welding head is selected, pure argon gas is introduced and ejected through the mixing inlet 642 to protect the tungsten electrode. The contact nozzle of the TIG welding head is connected to an external high-frequency arc-ignition power source, generating a non-contact arc between the tungsten electrode and the steel mesh. The welding wire is melted by the electric arc and fills the molten pool. The robotic arm moves the welding torch head 711 along the joint. The angle adjustment mechanism 4 maintains a 30° angle between the welding torch head 711 and the joint to ensure arc stability, thus completing the welding operation. A cleaning operation is required when using different welding torch heads 711 to clean the inner walls of the outer casing tube 811, the welding wire tube 812, and the gas tube 814, ensuring that these inner walls remain clean.
