Description

Technical Field

[0001] This utility model relates to the field of steel reinforcement floor decking processing technology, and in particular to an upper electrode mechanism and a template welding machine for welding and forming truss floor decking. Background Technology

[0002] The truss floor deck includes a base slab 100 and a steel truss 200, such as... Figure 7 As shown, the steel truss 200 includes web reinforcement 201, top chord reinforcement 202, and bottom chord reinforcement 203. In a traditional steel truss 200, the web reinforcement 201 has a base 204. During the production of the truss floor slab, after the steel truss 200 is welded, the base 204 is welded to the base slab 100, and finally, cement is poured for molding. When welding the steel truss 200 to the base slab 100, only the up-and-down movement of the welding machine is needed to coordinate with the synchronous horizontal movement of the steel truss 200 and the base slab 100 for sequential welding, resulting in high welding efficiency. For steel trusses 200 where the web reinforcement 201 does not have a base 204 at the bottom, such as... Figure 8 As shown, after the steel truss 200 is welded, multiple connecting seats 205 are installed on the base plate 100. First, the connecting seats 205 are fixedly connected to the base plate 100, generally in a detachable manner, such as bolted connection, so that the base plate 100 can be removed after pouring. Then, the lower chord reinforcement 203 is welded to the connecting seats 205 to obtain the truss floor slab. This scheme transforms the welding of the steel truss 200 to the base plate 100 into welding the lower chord reinforcement 203 to the connecting seats 205, making welding and disassembly of the base plate 100 more convenient. Figure 8 As can be seen, along the length of the steel truss 200, the welding point 300 and the bottom end of the web reinforcement 201 are both located at the lower chord reinforcement 203. Since traditional welding machines can only move up and down to perform multi-point welding, the upper electrode rod of the welding machine needs to rise above the top of the web reinforcement 201 after each welding point 300, and then descend back to the welding point during welding. This results in a large stroke of the upper electrode rod, affecting welding efficiency. If the vertical movement distance of the welding machine is not changed, the steel truss 200 and the base plate 100 will still move horizontally synchronously. This will cause the upper electrode rod of the welding machine to interfere with the position of the web reinforcement 201 in front of the welding point 300 during movement, resulting in a collision. Therefore, manual avoidance is required during the welding process, which is time-consuming and labor-intensive, affecting welding efficiency. Utility Model Content

[0003] The purpose of this utility model is to provide an upper electrode mechanism and a template welding machine to solve the problem of low welding efficiency between steel trusses with no bottom foot and the base plate.

[0004] To achieve this objective, the present invention adopts the following technical solution:

[0006] The upper electrode assembly is provided on the welding frame along the width direction of the base plate. Each set of upper electrode assemblies corresponds one-to-one with the multiple steel trusses to be welded on the base plate. Each set of upper electrode assemblies includes two upper electrode assemblies, and one upper electrode assembly is provided on each side of each steel truss.

[0007] A moving avoidance assembly is configured to drive two of the upper electrode assemblies in each group to move closer to or further away from each other along the width direction of the base plate.

[0008] In some embodiments, the movement avoidance component includes:

[0009] The avoidance rack is provided in two, the two avoidance racks are spaced apart and parallel to each other, and both avoidance racks extend along the width direction of the base plate. The two upper electrode assemblies in each group of upper electrode assemblies are respectively disposed on the two avoidance racks.

[0010] An avoidance gear is rotatably mounted on the welding frame and located between two avoidance racks. The teeth of the two avoidance racks are arranged opposite each other and mesh with the avoidance gear. When the avoidance gear rotates, it can drive the two avoidance racks to move in opposite directions, so that the two upper electrode assemblies in each set of upper electrode assemblies move in opposite directions.

[0011] In some embodiments, the avoidance rack is provided with a plurality of rack segments, and each rack segment is respectively connected to an avoidance gear.

[0012] In some embodiments, the moving avoidance assembly further includes a lateral drive member disposed on the welding frame. The output end of the lateral drive member is connected to any one of the upper electrode assemblies, any one of the avoidance racks, or any one of the avoidance gears. The lateral drive member is configured to drive any one of the upper electrode assemblies or any one of the avoidance racks to move along the width direction of the base plate, or to drive the avoidance gear to rotate, thereby causing two upper electrode assemblies in the same group to move closer to or further away from each other.

[0013] In some embodiments, the movement avoidance component further includes:

[0014] A slide rail extends along the width direction of the base plate and is fixed on the welding frame;

[0015] A slider is slidably mounted on the slide rail, an upper electrode assembly is disposed on the slider, and the output end of the transverse drive is connected to any one of the upper electrode assemblies.

[0016] In some embodiments, two slide rails are provided, which are respectively disposed on both sides of the upper electrode assembly along the length direction of the base plate. Two sliders positioned opposite each other on the two slide rails are provided with transition plates, and the upper electrode assembly is disposed on the transition plates.

[0017] In some embodiments, the upper electrode assembly includes:

[0018] A fixed base, which is slidably mounted on the welding frame and connected to the movable avoidance component;

[0019] A lifting drive component is mounted on the fixed base, and the output end of the lifting drive component passes vertically downward through the fixed base and is capable of telescopic movement.

[0020] An electrode holder is fixedly connected to the output end of the lifting drive component, and a round electrode is provided on the electrode holder for welding.

[0021] In some embodiments, the bottom end of the fixing seat is disposed on the transition plate and fixedly connected to the transition plate; the side of the fixing seat is provided with two mounting positions in the vertical direction, and two clearance racks are selectively installed in one of the mounting positions; the top end of the fixing seat is fixedly connected to the output end of the transverse drive member.

[0022] In some embodiments, the upper electrode mechanism of the template welding machine further includes a transformer, which is disposed on the welding frame and connected to the upper electrode assembly via a flexible wire.

[0023] A template welding machine includes a welding frame and an upper electrode mechanism of the template welding machine disposed on the welding frame.

[0024] The beneficial effects of this utility model are:

[0025] The upper electrode mechanism of the template welding machine provided by this utility model, by setting a moving avoidance component, has two avoidance racks meshing on one avoidance gear of the moving avoidance component. When the avoidance gear rotates, it can drive the two avoidance racks to move in opposite directions. Based on this principle, the two upper electrode components in the same group are respectively set on the two avoidance racks to realize the relative movement of the two upper electrode components in the same group. During welding, the two upper electrode components approach each other to align with the welding points and perform welding operations. After welding multiple welding points on a cross section, the two upper electrode components in the same group move away from each other along the width direction of the base plate to avoid the web reinforcement. The base plate and steel truss can move smoothly along the length direction of the base plate to the next welding section for sequential welding. No manual operation is required, and there is no need to change the lifting action of the existing upper electrode components. This solves the problem of reduced welding efficiency caused by positional interference between the base plate and steel truss during the movement process and the upper electrode components. It is suitable for the welding process of steel trusses with no bottom foot at the bottom of the web reinforcement and the base plate. Attached Figure Description

[0040] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0041] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0042] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0043] In the description of this embodiment, the terms "upper," "lower," "left," and "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, 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. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0044] This invention provides an upper electrode mechanism for a template welding machine, such as... Figures 1-6 As shown, the upper electrode mechanism of the template welding machine is mounted on the welding frame 1 and welds the steel truss 200 and the base plate 100 on the welding frame 1, as follows: Figure 8 As shown, the lower chord reinforcement 203 of the steel truss 200 is welded to the connecting seat 25 on the base plate 100. Figure 1 As shown, the upper electrode mechanism of the template welding machine includes an upper electrode assembly 2 and a moving avoidance assembly 3. Along the width direction (Y direction) of the base plate 100, multiple sets of upper electrode assemblies 2 are provided on the welding frame 1. Each set of upper electrode assemblies 2 is arranged one-to-one with multiple steel trusses 200 to be welded on the base plate 100. Each set of upper electrode assemblies 2 includes two upper electrode assemblies 2, and one upper electrode assembly 2 is arranged on each side of each steel truss 200. The moving avoidance assembly 3 is configured to drive the two upper electrode assemblies 2 in each set of upper electrode assemblies 2 to move closer to or further away from each other along the width direction of the base plate 100.

[0045] by Figure 1 As shown in the example, six steel trusses 200 are provided on the base plate 100 along its width direction (Y direction). Correspondingly, six sets of upper electrode assemblies 2 are provided on the welding frame 1, each set including two upper electrode assemblies 2. These two upper electrode assemblies 2 are respectively positioned directly above the welding points 300 on the steel trusses 200. As the base plate 100 drives the steel trusses 200 to move stepwise along the length direction (X direction) of the base plate 100, the step distance is the distance between two adjacent welding points 300. Multiple welding points 300 on the same cross-section are simultaneously welded and formed below multiple upper electrode assemblies 2, resulting in high welding efficiency. The upper electrode mechanism of the template welding machine provided in this embodiment can be used for welding and forming truss floor decks without bottom feet 204 at the bottom of the web reinforcement 201. Of course, it can also be used for welding and forming truss floor decks with bottom feet 204, except that the moving avoidance component 3 is not working or is not provided, making the welding process simpler and more efficient.

[0046] The upper electrode mechanism of the template welding machine provided by this utility model, by setting a moving avoidance component 3, drives the two upper electrode components 2 in the same group to move closer or further apart, such as... Figure 1As shown by the hollow arrow and the oblique filled arrow. During welding, the two upper electrode assemblies 2, which are set on both sides of the steel truss 200 in each group, move closer to each other to align with the welding points 300 and perform welding operations. After welding multiple welding points 300 on a cross section is completed, the base plate 100 and the steel truss 200 move forward synchronously by a set distance. The two upper electrode assemblies 2 in the same group move away from each other along the width direction of the base plate 100 to avoid the web reinforcement 201. The base plate 100 and the steel truss 200 can move smoothly along the length direction of the base plate 100 to the next welding section for sequential welding. No manual assistance is required during the welding process, and there is no need to change the lifting action of the existing upper electrode assembly 2. This solves the problem of reduced welding efficiency caused by positional interference between the base plate 100 and the upper electrode assembly 2 during the stepping movement of the steel truss 200 and the upper electrode assembly 2. It is suitable for welding processes of steel trusses 200 without bottom feet 204 at the bottom of web reinforcement 201 and base plate 100. Without changing the structure of the upper electrode assembly 2, the welding efficiency is greatly improved.

[0047] It should be noted that the moving avoidance component 3 simultaneously drives multiple sets of upper electrode components 2 to move closer or further away from each other, so that the multiple sets of upper electrode components 2 move in unison, thereby improving the welding process efficiency.

[0048] In some embodiments, the moving avoidance assembly 3 includes an avoidance rack 31 and an avoidance gear 32. There are two avoidance racks 31, which are spaced apart and parallel to each other. Both avoidance racks 31 extend along the width direction of the base plate 100. The two upper electrode assemblies 2 in each set of upper electrode assemblies 2 are respectively disposed on the two avoidance racks 31. The avoidance gear 32 is rotatably disposed on the welding frame 1 and located between the two avoidance racks 31. The teeth of the two avoidance racks 31 are arranged opposite to each other and respectively mesh with the avoidance gear 32. When the avoidance gear 32 rotates, it can drive the two avoidance racks 31 to move in opposite directions, so that the two upper electrode assemblies 2 in each set of upper electrode assemblies 2 move in opposite directions.

[0049] like Figure 3 As shown, two clearance racks 31 are arranged vertically at intervals, both extending along the Y-axis and parallel to each other. Two clearance racks 31 are simultaneously meshed on a clearance gear 32. When the clearance gear 32 rotates, or when either clearance rack 31 moves, it drives the two clearance racks 31 to move in opposite directions, i.e., the two clearance racks 31 move in the positive and negative Y-axis directions respectively. Based on this principle, two upper electrode assemblies 2 of the same group are respectively mounted on the two clearance racks 31, realizing the relative movement of the two upper electrode assemblies 2 of the same group. Figure 3As shown, in an embodiment with six groups of twelve upper electrode assemblies 2, the upper electrode assemblies 2 with odd numbers (i.e., 1, 3, 5, 7, 9, and 11) are simultaneously connected to the lower clearance rack 31, and the upper electrode assemblies 2 with even numbers (i.e., 2, 4, 6, 8, 10, and 12) are simultaneously connected to the upper clearance rack 31. This enables the synchronous clearance movement of multiple groups of upper electrode assemblies 2, improving production cycle time and welding efficiency.

[0050] In some embodiments, the avoidance rack 31 is provided with a plurality of rack segments 311, and each rack segment 311 is respectively connected to an avoidance gear 32.

[0051] like Figure 4 and Figure 5 As shown, in this embodiment, two rack segments 311 are spaced apart along the length of the avoidance rack 31. The two avoidance racks 31 have the same structure, and an avoidance gear 32 meshes between corresponding rack segments 311 on each of the two avoidance racks 31. Figure 3 Therefore, in the Y-direction, two clearance gears 32 support and transmit power between the clearance racks 31, which helps to improve the force balance and positional stability of the clearance racks 31. The two rack segments 311 are spaced apart and preferably located at the trisection points. The length of the rack segment 311 ensures that the clearance racks 31 and the clearance gears 32 are always in a meshed state. Furthermore, limiting structures can be provided at both ends of each rack segment 311 on the clearance racks 31 to prevent the two clearance racks 31 from disengaging from the clearance gears 32 after excessive movement.

[0052] In some embodiments, the moving avoidance component 3 further includes a lateral drive component 33, which is disposed on the welding frame 1. The output end of the lateral drive component 33 is connected to any one upper electrode component 2, any one avoidance rack 31, or any one avoidance gear 32. The lateral drive component 33 is configured to drive any one upper electrode component 2 or any avoidance rack 31 to move along the width direction of the base plate 100, or to drive the avoidance gear 32 to rotate, thereby causing the two upper electrode components 2 in the same group to move closer to each other or further away from each other.

[0053] By setting up the lateral drive component 33, the automatic control of the upper electrode assembly 2's movement to avoid the steel truss 200 can be achieved. The lateral drive component 33 is electrically driven and can perform telescopic reciprocating motion or forward and reverse motion (in which case a transmission component is set at the output end of the lateral drive component 33 to convert the rotational motion into linear motion) to drive the upper electrode assembly 2. Figure 3In the illustrated embodiment, the lateral drive component 33 is a cylinder. Of course, in other embodiments, a hydraulic cylinder or a linear motor can also be used, and the specific method is not limited. One end of the lateral drive component 33 is fixedly connected to one of the upper electrode components 2 in a group of upper electrode components 2. The output end of the lateral drive component 33 is connected to another upper electrode component 2 in the same group. Thus, when the output end of the lateral drive component 33 moves forward or backward, the two upper electrode components 2 in the same group move away from or towards each other. At the same time, the two avoidance racks 31 connected to it drive two of the other groups of upper electrode components 2 to move away from or towards each other. This achieves the synchronous expansion and avoidance of multiple groups of upper electrode components 2 with one action of the lateral drive component 33, thereby improving work efficiency.

[0054] When the transverse drive 33 is mounted on the welding frame 1, the output end of the transverse drive 33 is connected to a clearance rack 31 to move. The clearance rack 31 drives the clearance gear 32 to rotate, and the clearance gear 32 drives another clearance rack 31 to move in the opposite direction, thereby driving the two upper electrode assemblies 2 in each set of upper electrode assemblies 2 to move closer or further away from each other synchronously.

[0055] When the lateral drive 33 is connected to the avoidance gear 32, the lateral drive 33 drives the avoidance gear 32 to rotate, and the two avoidance racks 31 meshing on the avoidance gear 32 move in opposite directions, thereby driving the two upper electrode assemblies 2 in each set of upper electrode assemblies 2 to move closer or further away from each other synchronously.

[0056] In some embodiments, the moving avoidance component 3 further includes a slide rail 34 and a slider 35. The slide rail 34 extends along the width direction of the base plate 100 and is fixed on the welding frame 1. The slider 35 is slidably mounted on the slide rail 34. The upper electrode component 2 is disposed on the slider 35. The output end of the transverse drive component 33 is connected to any one of the upper electrode components 2.

[0057] By setting slide rails 34 and sliders 35, the upper electrode assembly 2 is slidably mounted to the welding frame 1, thus providing a stable sliding motion platform, i.e., slide rails 34, for the upper electrode assembly 2, which helps ensure the installation reliability and movement stability of the upper electrode assembly 2. Furthermore, multiple sets of upper electrode assemblies 2 are mounted on the same slide rail 34 to ensure consistency. Multiple sliders 35 are used, and the spacing between the sliders 35 ensures that the movement of the upper electrode assembly 2 does not interfere with each other. When multiple slide rails 34 are set, the multiple slide rails 34 along the Y direction are parallel to each other.

[0058] In some embodiments, two slide rails 34 are provided, and the two slide rails 34 are respectively disposed on both sides of the upper electrode assembly 2 along the length direction of the base plate 100. Two sliders 35 on the two slide rails 34 are provided with transition plates 36, and the upper electrode assembly 2 is disposed on the transition plates 36.

[0059] like Figure 2 As shown, along the length direction (X-direction) of the base plate 100, which is also the stepping direction of the base plate 100 and the steel truss 200, two slide rails 34 are provided. The two slide rails 34 are respectively located on the front and rear sides (on both sides along the X-direction) of multiple sets of upper electrode assemblies 2. Each upper electrode assembly 2 can be connected to two sliders 35 at opposite positions on the two slide rails 34, thereby improving the directionality and stability of the sliding movement of the upper electrode assembly 2, and the two sliders 35 can better install the upper electrode assembly 2, avoiding unstable position affecting welding accuracy. Figure 2 As shown, the slide rail 34 and the slider 35 have irregular cross sections (such as I-shaped or T-shaped cross sections) that cooperate with each other. When the slider 35 is slidably installed on the slide rail 34, the upper electrode assembly 2 is also slidably installed on the slide rail 34.

[0060] In some embodiments, the upper electrode assembly 2 includes a fixed base 21, a lifting drive 22, and an electrode seat 23. The fixed base 21 is slidably mounted on the welding frame 1 and connected to the movement avoidance component 3. The fixed base 21 is the body of the upper electrode assembly 2. When the fixed base 21 slides on the welding frame 1, under the action of the movement avoidance component 3, the two upper electrode assemblies 2 in the same group move closer or further apart under the drive of the fixed base 21. The lifting drive 22 is disposed on the fixed base 21, and the output end of the lifting drive 22 passes vertically downward through the fixed base 21 and can extend and retract. The electrode seat 23 is fixedly connected to the output end of the lifting drive 22, and a circular electrode 24 is provided on the electrode seat 23 for welding, thereby realizing the working control of the upper electrode assembly 2's vertical displacement for welding.

[0061] like Figure 6 As shown, a connecting seat 25 is provided on the fixed base 21, and the body of the lifting drive component 22 is fixed on the connecting seat 25. The fixed base 21 is fixed on the transition plate 36. The fixed base 21 is connected to the avoidance rack 31 of the moving avoidance component 3, and can move together with the moving avoidance component 3, so that the entire upper electrode component 2 can realize the avoidance function along the Y direction. The output end of the lifting drive component 22 is vertically downward and slides through the inner cavity of the fixed base 21. The output end of the lifting drive component 22 is provided with a guide post, which can increase the length of the output end of the lifting drive component 22 to facilitate the installation of the electrode seat 23. A round electrode 24 is provided on the electrode seat 23 for welding with the welding point 300. The lifting drive component 22 can be a linear drive component such as a cylinder or an electric cylinder.

[0062] In some embodiments, the bottom end of the fixed base 21 is disposed on the transition plate 36 and is fixedly connected to the transition plate 36; the side of the fixed base 21 is provided with two mounting positions in the vertical direction, and two clearance racks 31 are selectively installed in one of the mounting positions; the top end of the fixed base 21 is fixedly connected to the output end of the transverse drive member 33.

[0063] For example Figure 6 Generally, the transition plate 36 is provided with clearance holes. The guide rod 26 and the electrode seat 23 pass through the clearance holes and are located below the transition plate 36. The bottom end face of the fixing seat 21 abuts against the upper surface of the transition plate 36 and is then fixedly connected by bolts. The side of the fixing seat 21 is provided with a first mounting position 211 and a second mounting position 212, which are combined with... Figure 3 For odd-numbered upper electrode assemblies 2, the lower clearance rack 31 is fixedly connected to the lower second mounting position 212 on the fixed base 21. For even-numbered upper electrode assemblies 2, the upper clearance rack 31 is fixedly connected to the upper first mounting position 211 on the fixed base 21, realizing relative motion control of the two upper electrode assemblies 2 in the same group. The fixed connection method can be bolt connection. When the transverse drive 33 is connected to the upper electrode assembly 2, the body of the transverse drive 33 can be fixed on the welding frame 1, and the output end of the transverse drive 33 is connected to the fixed base 21 or the connecting seat 25 on the fixed base 21, realizing the drive of the upper electrode assembly 2. This realizes the installation of the upper electrode assembly 2.

[0064] In some embodiments, the upper electrode mechanism of the template welding machine further includes a transformer 4, which is mounted on the welding frame 1 and connected to the upper electrode assembly 2 via a flexible wire 5.

[0065] like Figure 2 As shown, the transformer 4 is mounted on the welding frame 1 to transmit current to the upper electrode assembly 2. Since the upper electrode assembly 2 has a moving motion along the Y direction, the length of the flexible wire 5 must meet the requirement of reliable connection of the upper electrode assembly 2 during movement.

[0066] This embodiment also provides a template welding machine, including a welding frame 1 and an upper electrode mechanism of the template welding machine mounted on the welding frame 1. When welding the lower chord 203 and the connecting seat 25, the template welding machine can control the upper electrode assembly 2 to avoid the web reinforcement 201 of the steel truss 200 during the welding process, thereby reducing labor intensity and improving welding efficiency.

[0067] The upper electrode mechanism of the template welding machine provided by this utility model is used to... Figure 8The steel truss 200 and the base plate 100 shown are welded together to form a truss floor deck. The bottom of the web reinforcement 201 lacks a base 204, requiring the lower chord reinforcement 203 of the steel truss 200 to be welded to the connecting seat 25 on the base plate 100. The connecting seat 25 is located at the center of the lower chord reinforcement 203 between two adjacent web reinforcements 201. During welding, two upper electrode assemblies 2 of the same group located on both sides of a steel truss 200 press down on the lower chord reinforcement 203 on both sides of the steel truss 200. After the lower chord reinforcement 203 abuts against the connecting seat 25, a closed circuit is formed due to the conductivity of the connecting seat 25, thereby generating resistance heat. A welding point 300 is formed between the lower chord reinforcement 203 and the connecting seat 25, achieving a welded connection. When the base plate 100 and the steel truss 200 move in a stepping motion to weld the next set of welding points 300, the upper electrode assembly 2 and the web reinforcement 201 will interfere with each other. Therefore, when the electrode seat 23 moves upward after the upper electrode assembly 2 has finished welding a welding point 300, the moving avoidance assembly 3 is activated. The lateral drive 33 drives one upper electrode assembly 2, and the remaining upper electrode assemblies 2, under the action of the avoidance rack 31 and the avoidance gear 32, move the two upper electrode assemblies 2 in the same group away from each other. At the same time, the upper and lower connecting seats 25 of the base plate 100 and the steel truss 200 move in a stepping motion to the bottom of the upper electrode assembly 2. This cycle is repeated to complete the welding.

[0068] It is understandable that during the welding process, the movement of the two upper electrode components 2 in each group moving closer or further apart, the lifting and lowering movement of the electrode seat 23 on each upper electrode component 2, and the stepping movement of the base plate 100 and the steel truss 200 along the X direction are all carried out simultaneously. By reasonably setting the movement speed and rhythm, the welding forming efficiency of the truss floor deck can be greatly improved.

Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here.
