Description

Technical Field

[0001] The present invention relates to the technical field of line connection systems, and in particular to a line connection system for an electric welding machine. Background Art

[0002] Electric welders are essential tools for repairing metal parts. For example, in typical harsh working conditions like the rolling and heating furnace areas of steel mills, maintenance personnel must tailor their work to the specific needs of the on-site repair location. For example, repairing cracks in rolled can bodies in the rolling area and welding worn elbows in the heating furnace area are crucial. Because components like rolled can bodies and elbows are immovable, maintenance personnel must use connecting cables to connect the welders in the repair area to the junction box at the work site. During this operation, maintenance personnel drag a connecting cable of appropriate length between the welder and the junction box, ultimately inserting the cable's plug into the corresponding jack in the junction box to complete the wiring process for a single welder.

[0003] However, when simultaneous operations in the rolling area of ​​a steel mill involve overhauling multiple rolling tank tilting devices and welding multiple burner components in the heating furnace area, multiple welding machines are often required to operate simultaneously, with each device independently completing these wiring operations. However, these specialized work areas are often subject to harsh working conditions such as dust, oil, and mechanical vibration. These include oil contamination from leaks in the heating furnace hydraulic system and high-frequency mechanical vibrations from the continuous operation of equipment such as the crusher and heating furnace fan in the rolling area. Of particular concern is the frequent presence of surface water in the rolling area due to the rapid cooling process during furnace rolling. Furthermore, the maintenance platforms in the heating furnace area often harbor water accumulation from leaks in the equipment cooling system. Therefore, long-term use of connecting cables in these work areas accelerates the aging and breakdown of their insulation. If conductive media such as standing water remain on the ground, the damaged connecting cables can come into direct contact with the water, posing a potential electric shock hazard. Consequently, if maintenance personnel or other on-site workers accidentally come into contact with standing water or exposed cables, they are at high risk of electric shock, a serious threat to personal safety.

[0004] In addition, since each welding machine requires a separate connecting cable for wiring operations, a large number of criss-crossing connecting cable lines will be formed at the work site, resulting in a messy maintenance area, which in turn leads to management difficulties and low troubleshooting efficiency. It cannot meet the needs of modern industrial safety production for high-reliability and high-safety connections.

[0005] Therefore, the above problems need to be solved urgently. Summary of the Invention

[0006] The purpose of the present invention is to provide a welding machine line connection system to reduce the mechanical damage caused by the movement of the cable, thereby delaying the aging of the insulation layer, reducing the risk of skin breakage, and further reducing the possibility of personnel contacting live media, thereby significantly improving the safety of electricity use.

[0007] To achieve this object, the present invention adopts the following technical solutions:

[0032] Before any embodiments of the present application are explained in detail, it is to be understood that the application is not limited in its application to the details of construction and the arrangement of components set forth in the following description or illustrated in the foregoing drawings.

[0033] In this application, the terms "comprises," "includes," "has," or any other variations thereof are intended to encompass non-exclusive inclusion, such that a process, method, article, or apparatus that includes a list of elements includes not only those elements but also other elements not explicitly listed, or elements inherent to such process, method, article, or apparatus. In the absence of further limitations, an element defined by the phrase "comprising a ..." does not preclude the presence of additional identical elements in the process, method, article, or apparatus that includes the element.

[0034] In this application, the term "and / or" is a description of the association relationship between related objects, indicating that three relationships can exist. For example, a centrifugal vortex magnetic pump and / or a centrifugal vortex magnetic pump can represent three situations: the existence of a centrifugal vortex magnetic pump alone, the existence of a centrifugal vortex magnetic pump and a centrifugal vortex magnetic pump at the same time, and the existence of a centrifugal vortex magnetic pump alone. In addition, the character " / " in this application generally indicates that the related objects are in an "and / or" relationship.

[0035] In this application, the terms "connect," "combine," "couple," and "install" may refer to direct connection, combination, coupling, or installation, or indirect connection, combination, coupling, or installation. For example, a direct connection refers to two parts or components being connected together without an intermediary, and an indirect connection refers to two parts or components being connected to at least one intermediary, with the two parts or components being connected via the intermediary. Furthermore, "connect" and "couple" are not limited to physical or mechanical connections or couplings and may include electrical connections or couplings.

[0036] In this application, it will be understood by those skilled in the art that relative terms (e.g., "about," "approximately," "substantially," etc.) used in conjunction with quantities or conditions include the values ​​and have the meaning indicated by the context. For example, the relative terms include at least the degree of error associated with the measurement of a specific value, the tolerance caused by manufacturing, assembly, use, etc. associated with a specific value. Such terms should also be considered to disclose a range defined by the absolute values ​​of the two endpoints. Relative terms may refer to plus or minus a certain percentage (e.g., 1%, 5%, 10% or more) of the indicated value. Numerical values ​​that do not use relative terms should also be disclosed as specific values ​​with tolerances. In addition, "substantially" may refer to plus or minus a certain degree (e.g., 1 degree, 5 degrees, 10 degrees or more) on the basis of the indicated angle when expressing a relative angular position relationship (e.g., substantially parallel, substantially perpendicular).

[0037] In this application, it will be understood by those skilled in the art that the function performed by an assembly can be performed by one assembly, multiple assemblies, one part, or multiple parts. Similarly, the function performed by a part can also be performed by one part, one assembly, or a combination of multiple parts.

[0038] In the present application, the terms "upper", "lower", "left", "right", "front", "back" and other directional words are described based on the orientation and positional relationship shown in the accompanying drawings, and should not be understood as limiting the embodiments of the present application. In addition, in the context, it is also necessary to understand that when it is mentioned that an element is connected to another element "upper" or "lower", it can not only be directly connected to the other element "upper" or "lower", but also be indirectly connected to the other element "upper" or "lower" through an intermediate element. It should also be understood that directional words such as upper side, lower side, left side, right side, front side, back side, etc. not only represent the positive orientation, but can also be understood as the lateral orientation. For example, below can include directly below, lower left, lower right, lower front and lower back, etc.

[0039] See also Figures 1 to 3 This embodiment provides a welding machine line connection system for enabling welding machines in multiple maintenance areas 100 to be connected to a junction box. The welding machine line connection system includes a transmission cable 1, a plurality of positive terminal posts 2, and a plurality of negative terminal posts 3.

[0040] Specifically, one end of a transmission cable 1 is connected to a junction box, and the transmission cable 1 passes through several maintenance areas 100 along a pre-set path. Several positive terminal posts 2 and several negative terminal posts 3 are connected to the transmission cable 1. These positive terminal posts 2 and negative terminal posts 3 are distributed throughout the multiple maintenance areas 100, with a one-to-one correspondence between the positive terminal posts 2 and the negative terminal posts 3 within any maintenance area 100. The positive input line of a welding machine can be connected to the transmission cable 1 via the positive terminal post 2, and the negative input line of the welding machine can be connected to the transmission cable 1 via the negative terminal post 3.

[0041] In this arrangement, the transmission cable 1 replaces the traditional independent connection cables of multiple welding machines. One end of the transmission cable 1 is connected to the junction box and passes through each maintenance area 100 along a preset path. In each maintenance area 100, a number of positive terminal posts 2 and a number of negative terminal posts 3 connected to the transmission cable 1 are set, and the positive terminal posts 2 and negative terminal posts 3 in the same maintenance area 100 correspond one to one. The positive input line and negative input line of the welding machine are connected to the transmission cable 1 through the positive terminal post 2 and negative terminal post 3 of the maintenance area 100 respectively. Therefore, the welding machines in multiple maintenance areas 100 can be connected to the junction box through the transmission cable 1, forming a power supply circuit.

[0042] It can be understood that by sharing the transmission cable 1, the number of on-site connection cables used is greatly reduced. The transmission cable 1 is arranged along a preset path to avoid wear and tear caused by frequent dragging of the cable by maintenance personnel, and the positive terminal post 2 and the negative terminal post 3 are fixedly installed in the maintenance area 100. The electric welder only needs to connect the positive input line to the positive terminal post 2 and the negative input line to the negative terminal post 3 over a short distance, which reduces the mechanical damage to the cable caused by movement, thereby slowing down the aging of the insulation layer and reducing the risk of skin breakage, thereby reducing the possibility of personnel contacting live media and significantly improving the safety of electricity use.

[0043] It can also be understood that by replacing multiple independent connecting cables with transmission cable 1, combined with the fixedly distributed positive and negative terminal posts 2 and 3, the line layout is clear and regular, avoiding the messy situation caused by the random pulling of connecting cables in traditional wiring methods. When troubleshooting is necessary, it is only necessary to conduct inspections around transmission cable 1 and the positive and negative terminal posts 2 and 3 in the corresponding maintenance area 100, without having to identify each of the numerous independent connecting cables one by one. This reduces the scope and complexity of the inspection, allows for rapid location of the fault point, improves management efficiency and the timeliness of fault handling, and meets the requirements of modern industrial production safety for high connection reliability and high safety.

[0044] In particular, the welding machine line connection system further includes a plurality of cover plates 4, which are distributed within a plurality of maintenance areas 100. Within any maintenance area 100, a cover plate 4 is provided corresponding to a positive terminal post 2 and a negative terminal post 3, such that the corresponding positive terminal post 2 and negative terminal post 3 correspond to the same cover plate 4. The cover plate 4 can be provided over the positive terminal post 2 and the negative terminal post 3 to isolate and insulate the positive terminal post 2 and the negative terminal post 3 from the external environment.

[0045] It is understandable that the cover plate 4 completely isolates the terminal post from pollutants in the external environment such as dust and oil through physical isolation, which can prevent pollutants from adhering to the conductive contact surface or gap of the terminal post. Combined with actual application scenarios, dust accumulation may cause the contact resistance of the terminal post to increase and heat up, and oil penetration may corrode the metal conductor or soften the insulation layer. The closed structure of the cover plate 4 can significantly delay such aging process. For example, in an environment with long-term metal processing dust, traditional exposed terminal posts may cause short circuits due to the formation of conductive paths due to dust accumulation. After adding the cover plate 4, the dust cannot contact the terminal post, which can reduce the incidence of such failures and extend the actual service life of the equipment.

[0046] It should be noted that the transmission cable 1 can be suspended using a bracket, and the transmission cable 1 can be fixed to the bracket, so as to avoid direct contact between the transmission cable 1 and conductive media such as ground water. The structure and size of the bracket are designed according to the actual application scenario. The design of the bracket is well known to those skilled in the art, so it will not be elaborated on.

[0047] It should also be noted that the cover 4 can be installed to the corresponding position of the bracket through a fixed snap-on, hinged or other structures. The specific installation method can be selected according to the actual application scenario. This embodiment does not make specific requirements and restrictions on this.

[0048] To improve ease of use, a positive pole marker 41 is provided at the position of the cover plate 4 corresponding to the positive terminal post 2, and a negative pole marker 42 is provided at the position of the cover plate 4 corresponding to the negative terminal post 3. By clearly marking the positive pole marker 41 and the negative pole marker 42 at the corresponding positions of the cover plate 4 in this manner, maintenance personnel can quickly complete polarity matching through intuitive visual guidance when wiring, avoiding the risk of internal circuit burnout, abnormal heating, or even short circuit fire caused by incorrect polarity connection. For example, if the negative input line is mistakenly connected to the positive terminal post 2, it may cause reverse breakdown of the rectifier element of the welding machine. The presence of the positive pole marker 41 and the negative pole marker 42 can greatly reduce the probability of such human error, thereby improving system reliability from the source of operation.

[0049] Furthermore, in traditional scenarios where multiple interconnected cables are interwoven, the chaotic routing of cables can easily lead to management difficulties such as misconnections, missed connections, and duplicate connections. The positive and negative pole markers 41 and 42 form standardized wiring nodes. That is, each cover plate 4 and its positive and negative pole markers 41 and 42 form an independent connection unit. Maintenance personnel do not need to memorize complex cable routings; they simply need to find the corresponding cover plate 4 based on the welder's location to complete the wiring, significantly reducing pre-operation line verification time.

[0050] It should be pointed out that an electric welder is a device that uses the high-temperature energy generated by arc discharge to melt the welding rod and the workpiece, thereby achieving welding of metal parts. From the perspective of line connection, the electric welder contains two sets of key cables, one of which is the input side cable and the other is the output side cable. The input side cable includes a positive input line and a negative input line, which serve as power lines for obtaining external power from the junction box to form a power supply circuit for the equipment. The output side cable includes a positive output line and a negative output line. The positive output line is used to connect the welding clamp, and the negative output line needs to be connected to the workpiece through a ground. When the welding clamp contacts the workpiece or an arc is generated, the current flows from the positive output line through the welding clamp, the arc, the workpiece, and the negative output line (ground end) to form a complete welding circuit, using arc heat or resistance heat to melt the metal to achieve welding.

[0051] During this process, reliable grounding of the negative output line is key to ensuring loop conduction and stable welding current. Poor grounding may lead to arc instability, abnormal heating of the equipment, and even safety hazards. To this end, in this embodiment, the welding machine line connection system also includes a plurality of grounding members 5, which are distributed in multiple maintenance areas 100, and the negative output line of the welding machine is connected to the grounding members 5.

[0052] When traditional multi-electric welding machines are in operation, the negative output line is often pulled arbitrarily due to the need for "grounding nearby", resulting in a messy ground cable and severe wear and tear from trampling. Therefore, the grounding piece 5 preset in each maintenance area 100 provides a unique or designated connection point for the negative output line. Maintenance personnel do not need to find the grounding location by themselves. They only need to connect the negative output line to the grounding piece 5 through a short-distance cable, avoiding surface wear and aging of the insulation layer caused by dragging the cable over long distances. It should be noted that the specific structure and position of the grounding piece 5 are well known to those skilled in the art, and need to be designed by those skilled in the art according to the actual application scenario, so it will not be described in detail.

[0053] To improve the safety of the welding machine, the welding machine line connection system also includes an adapter 6. The positive input line of the welding machine is detachably connected to the positive terminal post 2 through the adapter 6, and the negative input line of the welding machine is detachably connected to the negative terminal post 3 through the adapter 6. It can be understood that the detachable structure supports tool-free quick disconnect. When the welding machine needs to be moved or the power needs to be turned off urgently, maintenance personnel can instantly disconnect the power connection, avoiding the risk of arcing and ignition caused by dragging the cable in the live state.

[0054] To further enhance the safety of the welding machine, the welding clamp of the welding machine is detachably connected to the positive output line of the welding machine via an adapter 6. This arrangement allows the welding clamp to be detachably connected to the positive output line via the adapter 6, meaning that in a non-operating state, the connection between the welding clamp and the welding machine can be quickly disconnected, preventing the welding clamp from accidentally contacting a conductive medium (such as accumulated water or metal components) to form a charged circuit, thereby reducing the risk of electric shock caused by accidental contact. Furthermore, when it is necessary to replace welding clamps of different specifications, the detachable adapter 6 allows for rapid assembly and disassembly of the welding clamp, eliminating the need to repeatedly plug and unplug cables or adjust the wiring of the welding machine itself, thereby shortening downtime and improving maintenance efficiency.

[0055] In this embodiment, adapter 6 includes a terminal clamp 61, which can clamp or release the conductor. It is understood that terminal clamp 61 can quickly clamp or release the conductor, adapting to conductors of different diameters. It is convenient and efficient to operate, making it particularly suitable for scenarios requiring frequent plugging and unplugging. It should be noted that terminal clamp 61 is prior art and will not be described in detail.

[0056] Furthermore, the adapter 6 also includes a wire 62 and a magnetic connector 63, and the magnetic connector 63 and the wiring clamp 61 are respectively located at both ends of the wire 62. The magnetic connector 63 includes two magnetic parts 631 that can be attracted or separated, and the two magnetic parts 631 can be attracted and wrapped around the conductor to make the conductor conductive with the wire 62. It can be understood that the two magnetic parts 631 are automatically attracted when they are close to each other, without the need to press or rotate with the hands, and the operation is more convenient. At the same time, when separating, only a slight external force (such as lateral translation) needs to be applied to disconnect the magnetic adsorption, which is more convenient for use in emergency power outages. Specifically, the magnetic part 631 can be designed to be an arc-shaped or U-shaped opening, which can wrap a variety of conductive forms such as round cables, flat copper busbars, metal components, etc., without the need to match a specific interface shape, such as traditional terminals that need to correspond to screw holes.

[0057] In particular, the magnetic connector 63 further includes a connecting line 632 connecting the two magnetic parts 631. The two magnetic parts 631 are fixedly connected by the connecting line 632 (such as a flexible cable, a steel wire rope or a nylon rope) to form an inseparable whole to prevent one of the magnetic parts 631 from being lost.

[0058] In an emergency, such as when the welding tongs accidentally touch a conductive object other than the base metal, or when the insulation layer of wire 62 breaks, a high instantaneous current may flow through the circuit, potentially leading to serious consequences. Therefore, a fuse 64 is provided in the middle of wire 62. Fuse 64 can melt in the event of a high instantaneous current, thereby cutting off the power input and improving safety.

[0059] It should be noted that the fuse 64 is set in the middle of the wire 62 and can adopt a plug-in structure, embedded in the fuse seat inside the insulation layer of the wire 62, which is convenient for quick replacement by hand. A magnetic part 631 in the magnetic connector 63 is crimped or welded to one end of the wire 62 through a connecting wire 632 with a conductive core. The two magnetic parts 631 can attract and wrap the conductor. The other end of the wire 62 is hinged or bolted to the wiring clamp 61 and is connected. The clamp clamps the conductor through two clamps, thereby forming a complete conductive link of the magnetic connector 63, the wire 62 (including the fuse 64), and the wiring clamp 61.

[0060] Obviously, the above embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention and are not intended to limit the embodiments of the present invention. A person skilled in the art would be able to make various obvious changes, readjustments, and substitutions without departing from the scope of protection of the present invention. It is not necessary and impossible to enumerate all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the claims of the present invention.
