Description

Technical Field

[0001] This utility model relates to the field of welding equipment technology for power construction, and in particular to a rapid double-sided welding device for grounding round steel. Background Technology

[0002] During power construction, galvanized round steel with a diameter of 10mm to 14mm is commonly used for laying lightning protection grounding networks on power towers. According to construction specifications, the joints between round steel bars must be welded on both sides, and the overlap length must be no less than 6 times the diameter of the round steel bar. However, construction sites (especially in complex terrains such as mountains and paddy fields) often require the transport of large and heavy equipment such as generators and welding machines, making transportation extremely inconvenient.

[0003] Even more challenging is that welding operations using grounding rays are often carried out in narrow tunnels, where the limited space makes traditional double-sided welding operations extremely difficult. Welders struggle to maneuver their welding torches within the tunnel to ensure weld quality, leading to frequent problems such as poor weld formation, insufficient penetration, and slag inclusions, making it impossible to effectively control weld quality. Furthermore, manual welding is inefficient and poses safety hazards such as electric shock and burns.

[0004] Currently, although some automated welding equipment exists, most are designed for factory environments, are bulky, and cannot meet the portability and special space requirements of field power construction. Therefore, there is an urgent need for a specialized device that is highly integrated, portable, and capable of rapid, high-quality double-sided welding of grounding round steel in complex terrain field environments.

[0036] like Figures 1-2 As shown, this utility model embodiment provides a rapid double-sided welding device for grounded round steel, comprising:

[0037] Fixed base plate 1;

[0038] The fixing mechanism 2 is fixedly installed on the fixing base plate 1 and is used to horizontally clamp two parallel round steel bars 6 to be welded and grounded.

[0039] The double-sided welding actuator includes a first welding torch 31 and a second welding torch 32 symmetrically arranged on both sides of the fixing mechanism 2, a lateral movement module for driving the first welding torch 31 and the second welding torch 32 to move laterally, and a longitudinal movement module for driving the first welding torch 31 and the second welding torch 32 to feed longitudinally.

[0040] The motion control module 4 is electrically connected to the first welding torch 31, the second welding torch 32, the lateral movement module, and the longitudinal movement module, respectively; and

[0041] A portable power module is installed inside the mobile housing 5 to supply power to the double-sided welding actuator and motion control module 4.

[0042] It also includes an environmentally adaptable treatment system, which includes a heat-insulating protective cover and a spatter prevention device placed around the welding torch. The spatter prevention device is made of a transparent, high-temperature resistant material and has an anti-stick coating on its surface.

[0043] In this embodiment, the fixed base plate 1 serves as the fundamental load-bearing component of the entire device, providing a stable installation platform for core components such as the fixing mechanism 2 and the double-sided welding actuator. During transportation, the pull rod and rollers on one side of the fixed base plate 1 cooperate to form a handcart-style transportation structure, allowing operators to easily pull the device across complex terrains such as mountains and paddy fields without the need for additional handling equipment, thus solving the problem of difficult transportation of traditional welding equipment. Upon arrival at the construction site, the retractable support legs at the bottom of the fixed base plate 1 and the mobile housing 5 are unfolded, allowing the device to be placed stably on the ground or in narrow tunnels, preventing shaking during welding. The fixing mechanism 2 is fixedly installed on the fixed base plate 1 and is used to horizontally clamp two parallel grounded round steel bars 6 to be welded. The first welding torch 31 and the second welding torch 32 of the double-sided welding actuator are located on both sides of the fixing mechanism 2, respectively. The lateral movement module and the longitudinal movement module provide the motion power for the welding torches. The motion control module 4 is electrically connected to the welding torches and the movement module, coordinating the collaborative work of each component. The portable power module is installed inside the mobile housing 5, continuously supplying power to the entire system. During welding, the round steel bar 6 to be welded is firmly clamped by the fixing mechanism 2. The motion control module 4 issues commands to drive the horizontal and vertical movement modules, which in turn move the first welding torch 31 and the second welding torch 32 along a preset trajectory, simultaneously completing the double-sided welding operation. Throughout the process, the fixed base plate 1, with its robust structural design, ensures the installation accuracy and motion coordination of each component. Combined with a portable transportation structure and a stable power supply system, it enables rapid welding in confined spaces in the field. This not only improves welding efficiency but also avoids problems such as poor weld formation and insufficient penetration during manual welding, while reducing safety hazards such as electric shock and burns.

[0044] The innovation of the environmentally adaptable treatment system lies in its integration of heat insulation and anti-spatter functions. The selection of transparent, high-temperature resistant materials ensures both operational visibility and safety. The application of an anti-stick coating effectively solves the problem of welding spatter adhesion, extending equipment lifespan. This feature has significant practical value in complex field environments, addressing the technical challenge of insufficient protection for traditional welding equipment in harsh conditions. Transparent, high-temperature resistant materials can include quartz glass, borosilicate glass, sapphire glass, polyimide, and transparent ceramics, while the anti-stick coating can be made of polytetrafluoroethylene, ceramic coatings, silicone resins, carbon-based coatings, platinum-catalyzed silica gel, etc.

[0045] In some embodiments, the fixing mechanism 2 includes a fixing slot base 21 and at least a pair of quick-clamping clamps 22. The fixing slot base 21 has a semi-circular slot that matches the diameter of the round steel to be welded. The quick-clamping clamps 22 are mounted on both sides of the base via a rotating shaft and are used to clamp and fix the round steel placed in the slot.

[0046] In this embodiment, the fixing mechanism 2 consists of a fixed slot base 21 and at least one pair of quick-clamping clamps 22. The semi-circular slots on the fixed slot base 21 are precisely matched with the diameter of the round steel to be welded, ensuring that the round steel can be placed snugly. During construction, the operator first places two round steels 6 to be welded side by side in the semi-circular slots of the fixed slot base 21, adjusts the position of the round steels to align the joints, and ensures that the overlap length meets the construction specifications. Then, by rotating the quick-clamping clamps 22 installed on both sides of the base, the round steel placed in the slots is firmly clamped and fixed, preventing displacement of the round steel during welding. This fixing method is convenient to operate, requires no complicated tools, and can quickly complete the clamping and positioning of the round steel, significantly shortening the construction preparation time. Compared with the traditional manual hand-held fixing method, the clamping force provided by the quick-clamping clamps 22 is more uniform and stable, effectively preventing quality problems such as weld misalignment and slag inclusion caused by loosening of the round steel during welding. Meanwhile, the stable clamping state creates conditions for the precise operation of the double-sided welding actuator, enabling the first welding gun 31 and the second welding gun 32 to weld stably according to the preset trajectory, ensuring that the weld formation is beautiful and the penetration rate meets the standards, significantly improving the stability of welding quality and reducing the probability of rework caused by improper fixing.

[0047] The inner surface of the semi-circular slot is textured with wear-resistant and anti-slip patterns, and the edges of the slot are rounded to prevent scratches on the round steel surface. The wear-resistant and anti-slip patterns and rounded edges, through optimization of the slot structure, enhance clamping stability and prevent damage to the round steel surface. The wear-resistant patterns increase friction, preventing displacement of the round steel during welding; the rounded edges demonstrate a user-friendly design for product protection. This seemingly simple improvement effectively solves the practical problem of easily scratched round steel surfaces in existing technologies.

[0048] In some embodiments, the fixed slot base 21 is a detachable modular design, equipped with various specifications of slot bases suitable for round steel of different diameters, and the base is connected to the fixed base plate of the fixed base plate 1 by positioning pins and fastening bolts.

[0049] In this embodiment, the fixed slot base 21 adopts a detachable modular design and is equipped with various specifications to adapt to round steel of different diameters. The base is firmly connected to the fixed base plate 1 through positioning pins and fastening bolts. Before construction, according to the actual diameter of the round steel 6 to be welded for grounding, the corresponding specification of the fixed slot base 21 is selected. The positioning pins are quickly aligned with the installation position on the fixed base plate 1, and then the fastening bolts are tightened to complete the replacement and installation of the base. This design allows the device to flexibly adapt to round steel of different diameters within the range of Φ6 to Φ14mm, eliminating the need to equip welding equipment separately for round steel of different specifications, greatly improving the versatility and applicability of the device. In power construction, the laying of grounding grids often involves galvanized round steel of various diameters. The modular fixed slot base 21 allows operators to meet different welding needs without carrying multiple sets of fixing tools, simply by changing the base. This reduces construction costs and the number and weight of equipment carried, further enhancing the device's portability in the field. Meanwhile, the combination of positioning pins and fastening bolts ensures the accuracy and firmness of the base installation, avoids base displacement during welding which affects welding quality, and ensures that the device can maintain a stable and reliable operating state when welding round steel of different specifications.

[0050] The locating pin features a tapered design and a hardened surface treatment, ensuring a positioning accuracy error of less than 0.1 mm. The tapered locating pin and hardening treatment improve the positioning accuracy and durability during module replacement. The tapered design ensures automatic centering during base installation, while the hardening treatment extends the service life of the locating pin. The accuracy requirement of less than 0.1 mm guarantees the stability of welding quality, reflecting the stringent requirements for equipment precision.

[0051] In some embodiments, the lateral movement module includes a lateral lead screw 331, a lateral lead screw nut seat 332 driven by a first stepper motor 334, and a pair of lateral optical axis slide rails 333; the longitudinal movement module includes a longitudinal mounting plate 341 fixedly connected to the lateral lead screw nut seat 332, two longitudinal lead screws, and a longitudinal lead screw nut seat driven by a second stepper motor; the first welding torch 31 and the second welding torch 32 are respectively fixed to the two longitudinal lead screw nut seats by welding torch holders.

[0052] In this embodiment, the lateral movement module consists of a lateral lead screw 331, a lateral lead screw nut seat 332, a lateral optical axis slide rail 333, and a first stepper motor 334. The longitudinal movement module includes a longitudinal mounting plate 341 fixedly connected to the lateral lead screw nut seat 332, two longitudinal lead screws, a longitudinal lead screw nut seat, and a second stepper motor. The first welding torch 31 and the second welding torch 32 are respectively fixed to the two longitudinal lead screw nut seats by welding torch holders. During welding operations, the motion control module 4 issues a command, the first stepper motor 334 starts, driving the lateral lead screw 331 to rotate. The lateral lead screw nut seat 332 moves laterally along the lateral lead screw 331. At the same time, the lateral optical axis slide rail 333 provides guidance and support for the nut seat, ensuring the smoothness and straightness of the lateral movement. The longitudinal mounting plate 341 moves laterally synchronously with the lateral lead screw nut seat 332, driving the longitudinal movement module and the welding torch mounted on it to move laterally together, realizing the welding feed of the welding torch along the length direction of the round steel. When the distance between the welding torch and the round steel needs to be adjusted, the second stepper motor starts, driving the longitudinal lead screw to rotate. The longitudinal lead screw nut seat drives the welding torch to feed longitudinally, precisely controlling the distance between the welding torch and the weld, ensuring that the welding current and penetration depth meet the requirements. This dual-axis movement structure, driven by a stepper motor and lead screw transmission, has high motion precision and accurate control, enabling the welding torch to move smoothly along a preset trajectory. This avoids problems such as uneven weld width and penetration depth caused by uneven torch movement during manual operation. At the same time, the two longitudinal lead screws control the first welding torch 31 and the second welding torch 32 respectively. Combined with the synchronicity of lateral movement, this ensures that double-sided welding can be performed simultaneously, greatly improving welding efficiency and ensuring consistent weld quality on both sides, further guaranteeing the strength and reliability of the welded joint.

[0053] In addition, a guide groove 11 is provided on the fixed base plate 1, and a guide block 342 adapted to the guide groove 11 is provided on the longitudinal mounting plate 341.

[0054] Both the transverse and longitudinal lead screws employ ball screw structures, and their surfaces are chrome-plated for rust prevention. The ball screw structure and chrome plating improve transmission accuracy and corrosion resistance. Compared to ordinary lead screws, ball screws offer higher transmission efficiency and positioning accuracy, while the chrome plating adapts to the demands of humid outdoor environments. This improvement solves the problems of traditional transmission mechanisms being prone to corrosion and exhibiting poor accuracy retention in outdoor environments.

[0055] In some embodiments, the motion control module 4 includes a microprocessor controller and a motor driver. The microprocessor controller has a pre-stored welding program for controlling the coordinated movement of the first stepper motor 334 of the lateral movement module and the second stepper motor of the longitudinal movement module, so that the first welding torch 31 and the second welding torch 32 maintain synchronous and symmetrical movement during welding.

[0056] In this embodiment, the motion control module 4 includes a microprocessor controller and a motor driver. The microprocessor controller has pre-stored welding programs for round steel of different diameters and different welding requirements. Before welding, the operator selects the corresponding welding program through the control panel 7 according to the specifications of the round steel to be welded and the construction requirements. The microprocessor controller receives the instruction and processes it. During welding, the microprocessor controller sends control signals to the motor driver, driving the first stepper motor 334 of the lateral movement module and the second stepper motor of the longitudinal movement module to move in coordination. The first stepper motor 334 controls the rotation of the lateral lead screw 331, driving the welding torch to move at a constant speed along the length of the round steel. The second stepper motor controls the rotation of the longitudinal lead screw, precisely adjusting the welding feed of the welding torch to ensure uniform penetration. At the same time, the microprocessor controller strictly controls the speed and direction of the two stepper motors, so that the first welding torch 31 and the second welding torch 32 always maintain synchronous and symmetrical movement, that is, the lateral movement speed of the two welding torches is the same and the longitudinal feed is consistent, realizing the double-sided synchronous welding of the round steel joint. This precise collaborative control method completely solves the problem of ensuring synchronous welding on both sides during manual welding, avoiding situations where one side of the weld is too thick and the other side is too thin or incompletely penetrated. Pre-stored welding programs cover various construction scenarios, eliminating the need for operators to manually adjust complex parameters; they simply select the corresponding program to start welding, reducing operational difficulty while ensuring consistent and stable welding quality. High-quality welding can be achieved even in confined spaces, significantly improving construction efficiency and operational safety.

[0057] The microprocessor controller also integrates an adaptive welding parameter adjustment algorithm, which can automatically adjust the welding speed and current parameters according to the diameter of the round steel. This adaptive adjustment algorithm achieves intelligent welding control, automatically matching the optimal welding parameters and reducing the technical requirements on operators. This feature reflects the development of equipment towards intelligence and automation, solving welding quality problems caused by improper manual parameter settings.

[0058] In some embodiments, the grounded round steel rapid double-sided welding device further includes a weld locator, which includes a laser emitter mounted on the longitudinal mounting plate 341 for projecting a light spot onto the joint of the round steel to be welded before welding to assist in positioning.

[0059] In this embodiment, the core component of the weld seam locator is a laser emitter mounted on the longitudinal mounting plate 341, which provides a precise positioning reference for the welding torch before welding. During construction, after the operator fixes the round steel 6 to be welded to the fixing mechanism 2, the laser emitter is activated. The laser emitter projects a clear spot of light onto the joint of the round steel to be welded, visually marking the welding start position and weld path. By observing the position of the spot, the operator fine-tunes the placement of the round steel or the initial posture of the welding torch to ensure that the welding start point of the first welding torch 31 and the second welding torch 32 is precisely aligned with the joint. In narrow tunnels, where the light is dim and the operating space is limited, traditional manual positioning is difficult to accurately locate the joint, easily leading to welding torch deviation and problems such as incomplete welding or off-center welding. Laser spot positioning is intuitive and clear, unaffected by ambient light, and can quickly guide the operator to complete the positioning adjustment, significantly shortening the positioning time and improving the efficiency of construction preparation. At the same time, precise positioning ensures that the welding torch always welds along the joint, preventing the weld from deviating from the joint area, ensuring the continuity and integrity of the weld, improving the reliability of welding quality, and reducing rework and material waste caused by inaccurate positioning.

[0060] This embodiment also includes a weld quality monitoring system, comprising a high-definition camera and an image processing unit mounted next to the welding torch, for real-time monitoring of weld formation quality. The weld quality monitoring system applies visual inspection technology to welding process monitoring, enabling real-time feedback on weld quality. The high-definition camera, combined with image processing algorithms, can promptly identify weld defects, a feature that enhances the automation level of welding quality control.

[0061] In some embodiments, the portable power module includes a built-in 48V DC lithium battery pack and an external 220V AC power interface. The grounded round steel rapid double-sided welding device is equipped with a power management unit for automatically switching and managing the power supply from the built-in battery to the external AC power supply.

[0062] In this embodiment, the portable power module includes a built-in 48V DC lithium battery pack and an external 220V AC power interface. The internal power management unit is responsible for the automatic switching and management of the two power supply modes. In field construction scenarios, when there is no mains power supply, the power management unit automatically switches to the built-in lithium battery pack power supply mode. The 48V DC lithium battery pack provides stable power to all electrical components such as the motion control module 4 and the double-sided welding actuator, meeting the welding operation needs in field environments without external power. Depending on the construction requirements, a single built-in battery pack can support at least 5 welding joints, while an external battery pack can support ≥20 welding joints, meeting the endurance requirements of most field construction projects. When there is mains power supply at the construction site, the operator connects the external 220V AC power supply to the interface. The power management unit automatically detects and switches to the external AC power supply mode, while simultaneously charging the built-in lithium battery pack, enabling simultaneous operation and charging to ensure long-term continuous construction. The power management unit also features overvoltage, overcurrent, and undervoltage protection functions, enabling real-time monitoring of the power supply status. When voltage is abnormal or battery power is too low, it automatically cuts off the power or issues an alarm signal to protect the equipment from damage and prevent welding quality from being affected by unstable power supply. This dual-power supply design completely eliminates the reliance on large generators in traditional welding equipment, reducing equipment carrying capacity, lowering generator noise and fuel consumption, adapting to complex outdoor power supply environments, and improving the applicability and environmental friendliness of the device.

[0063] The power management unit also features intelligent power prediction, which can predict the remaining welding attempts based on historical welding data and provide early warnings. This intelligent power prediction function, through data analysis technology, provides power assurance for field construction. This function can rationally arrange the welding operation sequence, avoiding work interruptions due to insufficient power, demonstrating the intelligent development of power management.

[0064] In some embodiments, the outer wall of the mobile housing 5 is provided with a control panel 7, which integrates a one-button start button, an emergency stop button, a power switch, a battery power display screen, and a welding status indicator light.

[0065] In this embodiment, the control panel 7 integrated on the outer wall of the mobile housing 5 centrally arranges the one-button start, emergency stop, power switch, battery level display, and welding status indicator lights, facilitating intuitive operation and real-time monitoring of the equipment status by the operator. Before construction, the operator starts the device using the power switch. The battery level display shows the remaining power of the built-in lithium battery pack in real time, making it easy to determine whether the battery needs to be replaced or an external power source needs to be connected, avoiding welding interruptions due to insufficient power. After selecting the corresponding welding program and power supply mode, pressing the one-button start button initiates the welding operation according to the preset program, eliminating the need for complex parameter adjustments and lowering the operational threshold. During welding, the welding status indicator lights visually display the equipment's working status using different colored lights, such as green for normal welding, yellow for standby, and red for malfunction, allowing the operator to quickly grasp the equipment's operating status. In case of emergencies, such as personnel approaching the welding torch or abnormal equipment shaking, the operator can immediately press the emergency stop button. The device instantly cuts off all power and welding power, stopping all moving parts and preventing safety accidents. The audible and visual alarm function is automatically triggered when the equipment malfunctions or the battery is too low, promptly reminding the operator to take action and ensuring construction safety and welding quality. The user-friendly design of the control panel 7 simplifies the operation process, allowing even non-professionals to operate it proficiently after simple training. At the same time, real-time status monitoring and convenient emergency control functions further enhance the safety and reliability of the device.

[0066] The control panel 7 is also equipped with a touch screen display, which can display welding parameter curves and fault diagnosis information in real time. The touch screen display and parameter curve display enhance the human-machine interface experience, allowing operators to intuitively grasp the welding process status. The addition of fault diagnosis functionality improves the convenience of equipment maintenance and reduces downtime.

[0067] In some embodiments, the bottom of the fixed base plate 1 and / or the mobile box 5 is fixedly equipped with retractable support legs, and one side of the fixed base plate is provided with a pull rod and rollers for traction, forming a handcart-type transportation structure.

[0068] In this embodiment, the retractable outriggers at the bottom of the fixed base plate 1 and the movable housing 5, along with the pull rod and rollers on one side of the fixed base plate 1, together constitute a convenient integrated structure for transportation and support. During equipment transportation, the operator folds the retractable outriggers upwards, keeping them close to the bottom of the fixed base plate 1 or the movable housing 5 to prevent damage from collisions during transport. Then, the operator pulls the pull rod on one side of the fixed base plate 1, using the rollers at the bottom to move the entire device. This trolley-style design eliminates the need for the operator to carry or lift heavy equipment, allowing for easy transportation even on uneven terrain such as mountains and fields, solving the problems of large size and difficult handling associated with traditional welding equipment. Upon arrival at the construction site, the operator unfolds the retractable outriggers downwards and adjusts their height to keep the fixed base plate 1 level and stable, ensuring the device does not tilt or shift during welding. This structural design balances convenient transportation with operational stability; the entire machine weighs ≤40kg, and with the pull rod and rollers, a single person can complete the transportation and setup of the equipment, significantly reducing labor costs. Meanwhile, the retractable outriggers can adapt to the flatness requirements of different terrains. Even on uneven ground, the device can be placed stably by adjusting the height of the outriggers, providing a stable base environment for welding operations and ensuring that the welding quality is not affected by the terrain.

[0069] The outriggers are equipped with anti-slip pads and a height adjustment mechanism at the bottom, enabling them to adapt to uneven ground. These features enhance the equipment's stability in complex terrain, solving practical problems in field construction through simple mechanical structural innovation. This characteristic reflects a deep focus on user experience.

[0070] In some embodiments, the fixed base plate 1 is made of engineering aluminum alloy material, and its overall dimensions are ≤500mm in length, ≤400mm in width, ≤400mm in height, and the weight of the whole machine is ≤40kg.

[0071] In this embodiment, the fixed base plate 1 is made of engineering aluminum alloy, a material that combines high strength and lightweight, effectively reducing the overall weight of the device while ensuring structural stability. The overall dimensions of the fixed base plate 1 are controlled to be ≤500mm in length, ≤400mm in width, and ≤400mm in height, with a total weight of ≤40kg. Its compact size and light weight allow the device to easily enter narrow tunnels and other construction spaces, solving the problem of traditional welding equipment being too bulky to operate in confined environments. In field construction, the limited space inside tunnels makes it difficult for operators to deploy large equipment. The compact size of this device allows for flexible placement within the tunnel, and the first welding torch 31 and the second welding torch 32 can move smoothly on both sides of the fixed mechanism 2 to complete double-sided welding. Engineering aluminum alloy has excellent corrosion resistance and wear resistance, adapting to harsh environments such as dampness and dust in the field. It is not prone to rust or damage over long-term use, extending the device's service life. Simultaneously, the lightweight design not only facilitates transportation but also reduces the physical exertion of operators moving equipment in complex terrain, improving the ease of construction. The compact structural design allows for a reasonable layout of components, reducing space occupation. Components such as the portable power module and motion control module 4 are integrated into the mobile housing 5, protecting the core components from external collisions and environmental impacts, and further improving the reliability and durability of the device in the field.

[0072] The mobile enclosure 5 features a waterproof and dustproof design, achieving an IP54 protection rating, enabling it to withstand harsh outdoor environments. The IP54 protection rating ensures the equipment's reliability in harsh conditions, while the waterproof and dustproof design expands its applicability. This feature solves the key problem of poor environmental adaptability in traditional welding equipment.

[0073] Those skilled in the art will clearly understand that, for the sake of convenience and brevity, the specific working processes of the devices, apparatuses, and units described above can be referred to the corresponding processes in the foregoing method embodiments, and will not be repeated here.

[0074] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any person skilled in the art can easily conceive of various equivalent modifications or substitutions within the technical scope disclosed in this utility model, and these modifications or substitutions should all be covered within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
