Description

Technical Field

[0001] This invention relates to the field of welding equipment technology, and in particular to a welding device for the construction of steel structures for cable-stayed bridges. Background Technology

[0002] A cable-stayed bridge, also known as a skeletal bridge, is a type of bridge in which the main beam is directly attached to the bridge towers by numerous cables. It is a structural system composed of pressure-bearing towers, tension-bearing cables, and bending-bearing beams. It can be regarded as a multi-span elastically supported continuous beam in which cables replace piers. Furthermore, it can reduce the bending moment within the beam, lower the building height, reduce the structural weight, and save materials.

[0003] Cable-stayed bridges mainly consist of towers, main beams, and stay cables. During construction, a large amount of steel structure is used, and welding is unavoidable for connecting these structures. It's important to note that welding work on cable-stayed bridges is typically done outdoors, where the construction site itself generates significant dust. This dusty environment easily accumulates on heat sinks and air ducts, leading to a sharp decrease in heat dissipation efficiency. Traditional fixed fans cannot effectively remove dust from the welding machine's exterior. Furthermore, the high power of the welding machine means that internal components are prone to severe localized overheating when heat dissipation is poor, overloaded, or due to component aging. Traditional temperature control protection systems are relatively slow to respond and may fail to accurately locate hot spots, potentially causing expensive core components to burn out. Furthermore, due to the large amount of construction work involved in cable-stayed bridges, the welding machines are used for extended periods, which exacerbates the problem of overheating inside the machines. During the welding process, the welding machines need to be moved according to changes in the welding position, making them prone to tipping over due to being pulled or accidentally bumped. Welding machines are generally quite heavy, and tipping over can not only cause deformation of the outer casing and loosening or damage to internal components, but more fatally, if it falls on a damp, oily, or wet surface, it can easily cause electrical short circuits, corrosion, fires, or complete equipment failure. Summary of the Invention

[0004] The purpose of this invention is to provide a welding device for the construction of steel structures for cable-stayed bridges, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A welding device for the construction of a cable-stayed bridge steel structure includes a welding machine main unit, welding cables and power cables are respectively plugged into both sides of the welding machine main unit, and a cooling fan is installed inside the welding machine main unit.

[0007] It also includes a lifting dust blowing device, which is installed on the welding machine host and is used to blow dust and dissipate heat from the welding machine host; the lifting dust blowing device includes a lifting frame, which is slidably installed on the welding machine host, and multiple dust blowing heads are installed on the inner side of the lifting frame, and a dust blowing motor is installed on one side of the welding machine host, and a dust blowing pipe is connected between the dust blowing motor and the lifting frame;

[0008] The welding machine host is equipped with a high-temperature separation device, which is used to separate the welding machine host from the welding cable and the power cable. The high-temperature separation device includes two separation flip plates, which are rotatably mounted on both sides of the welding machine host. Each of the two separation flip plates is equipped with a separation pusher, which rotates to push the welding cable and the power cable to move. A separation drive frame is movably mounted on the top side of the welding machine host, and the separation drive frame is connected to the two separation flip plates. Active separation pushers are magnetically mounted on both sides of the welding machine host.

[0014] Furthermore, in a preferred embodiment of the present invention, the high-temperature separation device further includes two separation drive frames, which are slidably mounted on both sides of the welding machine host, and the separation drive frame is mounted on the two separation drive frames;

[0015] Separation baffles are installed on both of the separation flip plates, and the two separation drive frames are respectively used to prevent the two separation baffles from rotating.

[0016] Furthermore, in a preferred embodiment of the present invention, mounting seats are rotatably mounted on both sides of the separating flip plate, and the mounting seats are mounted on the welding machine host.

[0017] The mounting base is provided with a separation groove, and a separation shaft is rotatably mounted in the separation groove. The separation shaft is mounted on the separation flip plate, and the separation baffle is mounted on one of the separation shafts.

[0018] A separation torsion spring is installed on the inner wall of the separation groove, and the separation torsion spring is mounted on the separation shaft.

[0019] Furthermore, in a preferred embodiment of the present invention, two limiting seats are installed on the welding machine host, two driven slide grooves are opened on the bottom side of the separation drive frame, a sliding seat is slidably installed in the driven slide groove, and a transition plate is rotatably installed on one of the limiting seats and the sliding seat located on the same side;

[0020] A return spring is installed on the inner wall of the driven slide, and the return spring is mounted on the sliding seat.

[0021] Furthermore, in a preferred embodiment of the present invention, separation grooves are provided on both sides of the welding machine main body, and limit magnets are installed on the inner walls of the top and bottom sides of the separation grooves. A limiting magnetic plate is installed on the active separation pusher, and the limiting magnetic plate is attracted to the two limit magnets.

[0022] A pull-back spring is installed on the limiting magnetic plate, and the pull-back spring is installed on the inner wall of the separation groove.

[0023] Furthermore, in a preferred embodiment of the present invention, the flip-over isolation protection device further includes a plurality of protective rotating shafts, which are respectively mounted on a plurality of rotating isolation frames. A retraction groove is provided on the outer protective frame, and the rotating isolation frame is housed in the retraction groove. A plurality of angle limiting rods are installed on the inner wall of the retraction groove.

[0024] The protective outer frame is provided with multiple mounting slots, and the multiple protective rotating shafts are respectively rotatably installed in the multiple mounting slots;

[0025] A protective torsion spring is installed on the inner wall of the mounting slot, and the protective torsion spring is mounted on the protective rotating shaft.

[0026] Furthermore, in a preferred embodiment of the present invention, two synchronous push-pull plates are movably mounted on the protective outer frame, and a plurality of rectangular inserts are mounted on the synchronous push-pull plates;

[0027] Each of the multiple protective rotating shafts has a rectangular slot, and the multiple rectangular inserts are respectively inserted into the multiple rectangular slots.

[0028] Furthermore, in a preferred embodiment of the present invention, two extrusion pushers are movably mounted on the protective outer frame, and the two extrusion pushers are respectively mounted on the two synchronous push-pull plates;

[0029] The lifting frame has two storage slots, and storage springs are installed on the inner walls of the storage slots. The storage springs are installed on the synchronous push-pull plate.

[0030] The beneficial effects of the welding device for the construction of cable-stayed bridge steel structures proposed in this invention are:

[0031] In this invention, by setting up a lifting dust blowing device, when the welding machine host is in use, the dust blowing motor is started. When the cooling fan is started, it drives the lifting frame to move vertically. When the lifting frame moves, the air blown out by the dust blowing motor enters the lifting frame through the dust blowing pipe, and then blows out through multiple dust blowing heads, thereby achieving the purpose of cooling and dust blowing on the welding machine host. This can not only ensure the cleanliness of the welding machine host, but also further ensure the heat dissipation effect of the welding machine host.

[0032] Furthermore, in this invention, by setting up a high-temperature separation device, when the welding machine host overheats, the limiting magnet is heated and loses its magnetism. At this time, under the pull-back force of the pull-back spring, the limiting magnetic suction plate is pulled to move, causing the limiting magnetic suction plate to pull the active separation pusher to move. The movement of the active separation pusher pushes the transfer plate to rotate, and the rotation of the transfer plate drives the sliding seat to move, thereby driving the separation drive frame to move down. The separation drive frame drives the two separation drive frames to slide down on the welding machine host, causing the separation drive frames to disengage from the separation baffle. At this time, under the rebound force of the two separation torsion springs, the two separation shafts are driven to rotate, and the two separation shafts drive the separation flip plate to rotate, thereby causing the separation flip plate to drive the separation pusher to rotate, thus disengaging the welding cable and power cable from the welding machine host. This enables the power supply and welding cable to be disconnected in time when the welding machine host overheats, preventing the welding machine host from continuing to work when overheated, which could cause the welding machine host to burn out or even catch fire.

[0033] Furthermore, in this invention, by setting up a flip-over isolation protection device, if the welding machine host accidentally flips over during movement, causing the extrusion pusher to be squeezed and moved by the ground, it will drive the synchronous push-pull plate to move. The synchronous push-pull plate will cause multiple rectangular inserts to disengage from multiple rectangular slots, thus releasing the multiple protective rotating shafts from their constraints. At this time, under the torsional force of the protective torsion spring, the protective rotating shafts will drive the rotating isolation frame to rotate and unfold, and the rotation angle will be limited by the angle limiting rod, so that multiple rotating isolation frames located on the same side will unfold in a cross shape, thereby isolating one side of the welding machine host from the ground, preventing the welding machine host from directly contacting the ground when it flips over, and preventing water or impurities from entering the welding machine host and causing damage to the welding machine host. In addition, when the synchronous push-pull plate moves, it can also squeeze and separate the drive frame, achieving the purpose of detaching the welding cable and power cable from the welding machine host, further protecting the safety of the welding machine host.

All other embodiments obtained by those skilled in the art based on the embodiments of the invention without inventive effort are within the scope of protection of the invention.

[0047] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0048] Furthermore, in the description of this invention, it should be noted that the terms "center," "upper," "lower," "vertical," "horizontal," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the product of this invention is in use. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this invention.

[0051] Please refer to the attached instruction manual. Figures 1-10 The present invention provides a welding device for the construction of a cable-stayed bridge steel structure, which includes a welding machine host 1, welding cables 2 and power cables 3 respectively plugged into both sides of the welding machine host 1, and a cooling fan 4 installed inside the welding machine host 1.

[0052] Furthermore, in this embodiment of the invention, a lifting dust blowing device 5 is also included. The lifting dust blowing device 5 is installed on the welding machine host 1 and is used to blow dust and dissipate heat from the welding machine host 1. Specifically, the lifting dust blowing device 5 includes a lifting frame 501, which is slidably installed on the welding machine host 1. Multiple dust blowing heads 502 are installed on the inner side of the lifting frame 501, and a dust blowing motor 503 is installed on one side of the welding machine host 1. A dust blowing pipe 504 connects the dust blowing motor 503 and the lifting frame 501. It should be noted that in this embodiment of the invention, when the welding machine host 1 is in use, the lifting frame 501 moves vertically up and down, allowing the air blown out by the dust blowing motor 503 to enter the lifting frame 501 through the dust blowing pipe 504, and then blown out through the multiple dust blowing heads 502, thereby achieving the purpose of dissipating heat and blowing dust from the welding machine host 1. This ensures the cleanliness of the welding machine host 1 and further guarantees the heat dissipation effect of the welding machine host 1.

[0053] Please refer to the instruction manual attached. Figure 2 and Figures 5-7 Furthermore, the welding device for the construction of a cable-stayed bridge steel structure provided in this embodiment of the invention includes a high-temperature separation device 6 installed on the welding machine host 1. The high-temperature separation device 6 is used to separate the welding machine host 1 from the welding cable 2 and the power cable 3. Specifically, the high-temperature separation device 6 includes two separation flip plates 601, which are rotatably installed on both sides of the welding machine host 1. Each of the two separation flip plates 601 is equipped with a separation pusher 603, which rotates to push the welding cable 2 and the power cable 3 to move. A separation drive frame 604 is movably installed on the top side of the welding machine host 1. The separation drive frame 604 is connected to the two separation flip plates 601 in a transmission manner. Active separation pushers 615 are magnetically installed on both sides of the welding machine host 1. The active separation pushers 615 move to push the separation drive frame 604 to move, thereby driving the separation flip plates 601 to move.

[0054] It should be noted that in this embodiment of the invention, when the welding machine host 1 overheats due to a malfunction, the limiting magnet 618 is heated and loses its magnetism, which causes the separation drive frame 604 to drive the two separation drive frames 605 to slide down on the welding machine host 1. This causes the separation drive frames 605 to disengage from the separation baffle 608, thereby causing the separation flip plate 601 to drive the separation push frame 603 to rotate, disengaging the welding cable 2 and the power cable 3 from the welding machine host 1. This ensures that when the welding machine host 1 overheats, the power supply and welding cable 2 can be disconnected in time, preventing the welding machine host 1 from continuing to work when overheated, which could cause the welding machine host 1 to burn out or even catch fire.

[0055] More specifically, in this embodiment of the invention, a flip-over isolation protection device 7 is installed on the lifting dust blowing device 5. The flip-over isolation protection device 7 is used to isolate and protect the welding machine host 1. The flip-over isolation protection device 7 includes a protective outer frame 701, which is installed on the lifting frame 501. Multiple rotating isolation frames 702 are rotatably installed inside the protective outer frame 701. The rotating isolation frames 702 rotate and unfold to support the welding machine host 1. It should be noted that in this embodiment of the invention, when the welding machine host 1 accidentally flips over, the multiple rotating isolation frames 702 rotate and unfold, and the rotation angle is limited by the angle limiting rod 704. This causes the multiple rotating isolation frames 702 located on the same side to unfold in a cross shape, thereby isolating one side of the welding machine host 1 from the ground and preventing the welding machine host 1 from directly contacting the ground when it flips over, thus preventing water or impurities from entering the welding machine host 1 and causing damage to the welding machine host 1.

[0056] Please continue to refer to the instruction manual appendix. Figures 1-10 Furthermore, the welding device for the construction of a cable-stayed bridge steel structure provided in this embodiment of the invention includes a lifting dust blowing device 5 that further includes multiple lifting restriction bars 505, all of which are installed on the welding machine host 1.

[0057] In addition, a lifting limit groove 506 is provided on the lifting limit bar 505, and a lifting slide 507 is slidably installed in the lifting limit groove 506. The lifting slide 507 is installed on the lifting frame 501. It should be noted that in this embodiment of the invention, the transmission gear 509 rotates on the lifting limit bar 505 via a transmission shaft 508. Simultaneously, the transmission gear 509 rotates via a transmission chain 510, driving another transmission gear 509 to rotate. During the rotation of the transmission chain 510, the lifting drive shaft 511 moves, causing the lifting drive shaft 511 to drive the lifting slide 507 to slide within the lifting limit groove 506, thus achieving vertical movement of the lifting slide 507. In addition, when the transmission chain 510 rotates one revolution, it drives the lifting slide 507 to move vertically once, thereby driving the lifting frame 501 to move vertically. When the lifting frame 501 moves, the air blown by the dust blowing motor 503 enters the lifting frame 501 through the dust blowing pipe 504, and then is blown out through multiple dust blowing heads 502, achieving the purpose of heat dissipation and dust blowing for the welding machine host 1.

[0058] Please refer to the instruction manual attached. Figures 2-4 More specifically, in this embodiment of the invention, two transmission shafts 508 are rotatably mounted on a lifting limit bar 505, and transmission gears 509 are mounted on both transmission shafts 508. Transmission chains 510 mesh on the two transmission gears 509, and lifting drive shafts 511 are mounted on the transmission chains 510. The lifting drive shafts 511 are movably mounted on a lifting slide 507.

[0059] Furthermore, a transfer drive shaft 512 is installed on the cooling fan 4. Both the transfer drive shaft 512 and a transmission shaft 508 are equipped with drive gears 513, and a drive chain 514 meshes with the two drive gears 513. It should be noted that, in this embodiment of the invention, when the cooling fan 4 starts, it drives the transfer drive shaft 512 to rotate, which in turn drives one drive gear 513 to rotate. The rotation of the drive gear 513, through the drive chain 514, drives the other drive gear 513 to rotate, which in turn drives a transmission gear 509 to rotate, thus achieving the purpose of lifting and blowing dust using the cooling fan 4.

[0060] Please refer to the instruction manual attached. Figure 2 and Figures 5-7 Furthermore, the welding device for the construction of a cable-stayed bridge steel structure provided in this embodiment of the invention includes a high-temperature separation device 6 that further includes two separation drive frames 605. The two separation drive frames 605 are slidably installed on both sides of the welding machine host 1, and the separation drive frame 604 is installed on the two separation drive frames 605.

[0061] Furthermore, each of the two separating flip plates 601 is equipped with a separating baffle 608, and two separating drive frames 605 are used to prevent the two separating baffles 608 from rotating. It should be noted that, in this embodiment of the invention, when the welding machine host 1 overheats, the active separating push frame 615 pushes the adapter plate 614 to rotate, which in turn causes the separating drive frame 604 to drive the two separating drive frames 605 to slide downward on the welding machine host 1, thereby causing the separating drive frames 605 to disengage from the separating baffles 608, achieving the purpose of automatically unlocking the separating baffles 608.

[0062] More specifically, in this embodiment of the invention, mounting seats 602 are rotatably mounted on both sides of the separating flip plate 601, and the mounting seats 602 are mounted on the welding machine host 1; a separating rotating groove 606 is opened on the mounting seat 602, and a separating rotating shaft 607 is rotatably mounted in the separating rotating groove 606. The separating rotating shaft 607 is mounted on the separating flip plate 601, and a separating baffle 608 is mounted on one of the separating rotating shafts 607; in addition, a separating torsion spring 609 is installed on the inner wall of the separating rotating groove 606, and the separating torsion spring 609 is mounted on the separating rotating shaft 607. It should be noted that in this embodiment of the invention, when the separating drive frame 605 disengages from the separating baffle 608, the two separating rotating shafts 607 are driven to rotate under the rebound force of the two separating torsion springs 609, so that the two separating rotating shafts 607 drive the separating flip plate 601 to rotate, and then the separating flip plate 601 drives the separating push frame 603 to rotate, thereby achieving the purpose of disengaging the welding cable 2 and the power cable 3 from the welding machine host 1.

[0063] Please continue to refer to the instruction manual appendix. Figure 2 and Figures 5-7 More specifically, in this embodiment of the invention, two limiting seats 610 are installed on the welding machine host 1, and two driven slide grooves 612 are opened on the bottom side of the separation drive frame 604. A sliding seat 611 is slidably installed in the driven slide groove 612, and a connecting plate 614 is rotatably installed on one of the limiting seats 610 and the sliding seat 611 located on the same side.

[0064] Furthermore, a return spring 613 is installed on the inner wall of the driven slide 612, and the return spring 613 is mounted on the sliding seat 611. It should be noted that, in this embodiment of the invention, the active separation pusher 615 moves to push the adapter plate 614 to rotate. The adapter plate 614 rotates on the limiting seat 610. At the same time, the rotation of the adapter plate 614 drives the sliding seat 611 to move, so that the sliding seat 611 slides in the driven slide 612, and the return spring 613 is subjected to force. When the adapter plate 614 rotates, it drives the separation drive frame 604 to move downward through the sliding seat 611, thereby achieving the purpose of the separation drive frame 604 driving the two separation drive frames 605 to slide downward on the welding machine host 1.

[0065] More specifically, in this embodiment of the invention, separation grooves 616 are provided on both sides of the welding machine host 1. Limiting magnets 618 are installed on the inner walls of the top and bottom sides of the separation grooves 616. A limiting magnetic plate 617 is installed on the active separation pusher 615, and the limiting magnetic plate 617 is attracted to the two limiting magnets 618. A pull-back spring 619 is installed on the limiting magnetic plate 617, and the pull-back spring 619 is installed on the inner wall of the separation groove 616. It should be noted that in this embodiment of the invention, when the welding machine host 1 overheats due to a malfunction, the limiting magnets 618 become heated and lose their magnetism. At this time, under the pull-back force of the pull-back spring 619, the limiting magnetic plate 617 is pulled to move, causing the limiting magnetic plate 617 to pull the active separation pusher 615 to move. The movement of the active separation pusher 615 pushes the adapter plate 614 to rotate, thereby achieving the purpose of detaching the welding cable 2 and the power cable 3 from the welding machine host 1.

[0066] Please refer to the instruction manual attached. Figure 2 and Figures 8-10 Furthermore, the welding device for the construction of a cable-stayed bridge steel structure provided in this embodiment of the invention includes a flip-over isolation protection device 7, which further includes multiple protective rotating shafts 706. The multiple protective rotating shafts 706 are respectively installed on multiple rotating isolation frames 702. A retraction groove 703 is provided on the protective outer frame 701. The rotating isolation frame 702 is housed in the retraction groove 703. Multiple angle limiting rods 704 are installed on the inner wall of the retraction groove 703.

[0067] Furthermore, the protective outer frame 701 is provided with multiple mounting slots 705, and multiple protective rotating shafts 706 are rotatably installed in the multiple mounting slots 705 respectively; a protective torsion spring 707 is installed on the inner wall of the mounting slot 705, and the protective torsion spring 707 is installed on the protective rotating shaft 706. It should be noted that, in this embodiment of the invention, when the welding machine host 1 is overturned, the extrusion pusher 711 is squeezed and moved by the ground, which releases the restriction of the multiple protective rotating shafts 706. At this time, under the torsional force of the protective torsion spring 707, the protective rotating shaft 706 drives the rotating isolation frame 702 to rotate and unfold, and the rotation angle is limited by the angle limiting rod 704, thereby causing the multiple rotating isolation frames 702 located on the same side to unfold in a cross shape, thereby isolating one side of the welding machine host 1 from the ground, avoiding the welding machine host 1 from directly contacting the ground when it is overturned, so that water or impurities can enter the welding machine host 1 and cause damage to the welding machine host 1.

[0068] More specifically, in this embodiment of the invention, two synchronous push-pull plates 709 are movably mounted on the protective outer frame 701, and multiple rectangular inserts 710 are mounted on the synchronous push-pull plates 709; multiple protective rotating shafts 706 are each provided with rectangular slots 708, and the multiple rectangular inserts 710 are respectively inserted into the multiple rectangular slots 708. It should be noted that, in this embodiment of the invention, the movement of the synchronous push-pull plates 709 causes the multiple rectangular inserts 710 to disengage from the multiple rectangular slots 708, thereby releasing the multiple protective rotating shafts 706 from restriction, and causing the protective rotating shafts 706 to drive the rotating isolation frame 702 to rotate and unfold, thereby achieving the purpose of actively isolating the welding machine host 1.

[0069] Please continue to refer to the instruction manual appendix. Figure 2 and Figures 8-10 More specifically, in this embodiment of the invention, two extrusion pushers 711 are movably mounted on the protective outer frame 701, and the two extrusion pushers 711 are respectively mounted on two synchronous push-pull plates 709;

[0070] In addition, two storage slots 712 are provided on the lifting frame 501, and storage springs 713 are installed on the inner walls of the storage slots 712. It should be noted that, in this embodiment of the invention, when the welding machine host 1 is tilted to the side, the extrusion pusher 711 is pressed and moved by the ground, which in turn drives the synchronous push-pull plate 709 to move, and causes the storage springs 713 to be stretched by force, thereby achieving the purpose of automatically unlocking the multiple rotating isolation frames 702; in addition, when the synchronous push-pull plate 709 moves, it can also extrude and separate the drive frame 605, which can also achieve the purpose of detaching the welding cable 2 and the power cable 3 from the welding machine host 1, further protecting the safety of the welding machine host 1.

[0071] In summary, the working principle of the welding device for the construction of a cable-stayed bridge steel structure provided in this embodiment of the invention is as follows:

[0072] When the welding machine host 1 is in use, the welding cable 2 and power cable 3 need to be plugged into the welding machine host 1, and the cooling fan 4 is used for heat dissipation. At the same time, the dust blowing motor 503 is started. When the cooling fan 4 is started, it drives the adapter drive shaft 512 to rotate, which in turn drives one drive gear 513 to rotate. The rotation of drive gear 513 drives another drive gear 513 to rotate through the drive chain 514, which in turn drives a transmission gear 509 to rotate. The rotation of transmission gear 509 rotates on the lifting limit bar 505 through a transmission shaft 508. At the same time, the rotation of one transmission gear 509 drives another transmission gear 509 to rotate through the transmission chain 510. It should be noted that during the rotation and transmission process, the transmission chain 510 drives the lifting drive shaft 511 to move, causing the lifting drive shaft 511 to drive the lifting slide 507 to slide within the lifting limit groove 506, thereby realizing the vertical movement of the lifting slide 507. When the transmission chain 510 rotates one revolution, it drives the lifting slide 507 to move vertically once, which in turn drives the lifting frame 501 to move vertically. When the lifting frame 501 moves, the air blown by the dust blowing motor 503 enters the lifting frame 501 through the dust blowing pipe 504, and then blows out through multiple dust blowing heads 502, thereby achieving the purpose of heat dissipation and dust blowing for the welding machine host 1. This ensures both the cleanliness of the welding machine host 1 and further guarantees the heat dissipation effect of the welding machine host 1.

[0073] Furthermore, when the welding machine host 1 overheats due to an unexpected malfunction, environmental factors, or other reasons, the limiting magnet 618 loses its magnetism due to heat. At this time, under the pull-back force of the pull-back spring 619, the limiting magnetic suction plate 617 is pulled to move, causing the limiting magnetic suction plate 617 to pull the active separation pusher 615 to move. The movement of the active separation pusher 615 pushes the transfer plate 614 to rotate. The transfer plate 614 rotates on the limiting seat 610. At the same time, the rotation of the transfer plate 614 drives the sliding seat 611 to move, causing the sliding seat 611 to slide in the driven slide groove 612, and causing the return spring 613 to be stressed. In addition, when the transfer plate 614 rotates, the sliding seat 611 drives the separation... The separation drive frame 604 moves downward, causing the separation drive frame 604 to drive the two separation drive frames 605 to slide downward on the welding machine host 1. This causes the separation drive frames 605 to disengage from the separation baffle 608. At this time, under the rebound force of the two separation torsion springs 609, the two separation rotating shafts 607 are driven to rotate, causing the two separation rotating shafts 607 to drive the separation flip plate 601 to rotate. This causes the separation flip plate 601 to drive the separation push frame 603 to rotate, disengaging the welding cable 2 and the power cable 3 from the welding machine host 1. This allows the power supply and welding cable 2 to be disconnected in time when the welding machine host 1 overheats, preventing the welding machine host 1 from continuing to work when overheated, which could cause the welding machine host 1 to burn out or even catch fire.

[0074] Furthermore, if the welding machine host 1 accidentally overturns during movement, the extrusion pusher 711 is pressed and moved by the ground, which in turn moves the synchronous push-pull plate 709, causing the storage spring 713 to be stretched. The movement of the synchronous push-pull plate 709 causes multiple rectangular inserts 710 to disengage from multiple rectangular slots 708, thereby releasing the multiple protective rotating shafts 706 from their restraints. At this time, under the torsional force of the protective torsion spring 707, the protective rotating shafts 706 cause the rotating isolation frame 702 to rotate and unfold, and are restrained by the angle limiting rod 704. The rotation angle causes multiple rotating isolation frames 702 located on the same side to spread out in a cross shape, thereby isolating one side of the welding machine host 1 from the ground. This prevents the welding machine host 1 from directly contacting the ground when it tipes over, thus preventing water or impurities from entering the welding machine host 1 and causing damage. In addition, when the synchronous push-pull plate 709 moves, it can also squeeze and separate the drive frame 605, which can also achieve the purpose of detaching the welding cable 2 and power cable 3 from the welding machine host 1, further protecting the safety of the welding machine host 1.
