Description

Technical Field

[0001] The utility model relates to the field of steel structure manufacturing, and particularly relates to a welding track and a welding trolley assembly. Background Art

[0002] With the development of the steel structure industry, in order to meet the needs of building shapes, many steel components need to be processed into arc-shaped bends. There are many difficulties in the production process of such steel components, and one of them is the welding of arc-shaped welds. The commonly used welding method is submerged arc welding. Submerged arc welding is an automated welding method that relies on a submerged arc welding equipment, namely a submerged arc welding trolley, to fill and cover the groove, with advantages such as stable weld quality, excellent forming, and outstanding efficiency. However, the submerged arc welding trolley can generally only be used for welding common straight welds. For some arc-shaped welds, it is necessary to continuously adjust the position of the track during welding for segmented welding, resulting in too many weld butt joints, unstable forming, and a greater impact on welding efficiency. Summary of the Utility Model

[0003] In view of this, the utility model provides a welding track and a welding trolley assembly to solve the problem that when the submerged arc welding trolley welds some arc-shaped welds, it is necessary to continuously adjust the position of the track for segmented welding, resulting in too many weld butt joints, unstable forming, and a greater impact on welding efficiency.

[0004] In a first aspect, the utility model provides a welding track, which is arc-shaped and used to guide the traveling route of a welding trolley 8. The welding track includes:

[0005] A first arc-shaped backing plate and a second arc-shaped backing plate, arranged in parallel;

[0006] A first limiting strip, fixedly connected to the upper end surface of the first arc-shaped backing plate, and the radian of the first limiting strip is adapted to the radian of the first arc-shaped backing plate;

[0007] A second limiting strip, fixedly connected to the upper end surface of the second arc-shaped backing plate, and the radian of the second limiting strip is adapted to the radian of the second arc-shaped backing plate; the first limiting strip and the second limiting strip are adapted to abut against the wheels of the welding trolley to restrict the rolling direction of the wheels.

[0008] Beneficial effects: By restricting the rolling direction of the wheels through the first limiting strip and the second limiting strip, the traveling route of the welding trolley is guided, so that the welding trolley moves along the arc-shaped welding track and performs curve welding, thereby avoiding continuously adjusting the track position for segmented welding during welding, which is beneficial to reducing the number of weld butt joints, improving the forming stability of steel components and welding efficiency.

[0009] In an optional embodiment, the first limiting strip includes an arc-shaped round rod; the second limiting strip includes an arc-shaped round rod.

[0010] In an alternative embodiment, the widths of the first arc-shaped backing plate and the second arc-shaped backing plate are both H, where 15 mm ≤ H ≤ 45 mm.

[0011] Beneficial effects: By making the widths of the first arc-shaped backing plate and the second arc-shaped backing plate greater than or equal to 15 mm and less than or equal to 45 mm, it is possible to avoid an increase in the cost of the welding track when the width is too large, and to avoid a situation where the width is too small, which affects the stability of the welding track placed on the ground or the surface of the workbench.

[0012] In an alternative embodiment, the lengths of the first arc-shaped backing plate and the second arc-shaped backing plate are both S, where 4000 mm ≤ S ≤ 6000 mm.

[0013] Beneficial effects: By making the lengths of the first arc-shaped backing plate and the second arc-shaped backing plate greater than or equal to 4000 mm and less than or equal to 6000 mm, it is possible to avoid an increase in the manufacturing difficulty caused by an overly long welding track, and to avoid a situation where the welding track is too short, which requires intermittent movement of the position of the welding track, resulting in a decrease in welding efficiency.

[0014] In an alternative embodiment, the welding track further includes a first limiting block and a second limiting block. The first limiting block is fixedly connected to the first arc-shaped backing plate and abuts against the outer peripheral wall of the first limiting strip to form a limit for the movement of the first limiting strip relative to the first arc-shaped backing plate along the radial direction of the welding track; the second limiting block is fixedly connected to the second arc-shaped backing plate and abuts against the outer peripheral wall of the second limiting strip to form a limit for the movement of the second limiting strip relative to the second arc-shaped backing plate along the radial direction of the welding track.

[0015] Beneficial effects: By forming a limit on the outer peripheral wall of the first limiting strip through the first limiting block, the connection stability between the first limiting strip and the first arc-shaped backing plate is improved; and by forming a limit on the outer peripheral wall of the second limiting strip through the second limiting block, the connection stability between the second limiting strip and the second arc-shaped backing plate is improved.

[0016] In an alternative embodiment, the welding track further includes a connecting member disposed between the first arc-shaped backing plate and the second arc-shaped backing plate. One end of the connecting member is fixedly connected to the first arc-shaped backing plate, and the other end is fixedly connected to the second arc-shaped backing plate.

[0017] Beneficial effects: By fixedly connecting a connecting member between the first arc-shaped backing plate and the second arc-shaped backing plate, it is convenient to enhance the overall stability of the welding track.

[0018] In an alternative embodiment, the number of the connecting members includes a plurality. Along the length direction of the welding track, the spacing between two adjacent connecting members is L, where 500 mm ≤ L ≤ 800 mm.

[0019] Beneficial effects: By providing a plurality of connecting members and arranging them at intervals of 500 mm to 800 mm along the length direction of the welding track, it is beneficial to further enhance the overall stability of the welding track.

[0020] In an alternative embodiment, the connecting member includes a flat plate.

[0021] In an alternative embodiment, the length of the connecting member is 350 mm.

[0022] Beneficial effects: The length of the connecting member includes multiple specifications to be suitable for fixedly connecting the first limiting strip and the second limiting strip with different spacing intervals, so as to be applicable to welding trolleys of different specifications and sizes, which is beneficial to improving the applicability of the welding track.

[0023] In a second aspect, the present invention further provides a welding trolley assembly, including:

[0024] A welding trolley;

[0025] The above-mentioned welding track, the welding trolley is installed on the welding track, and the welding trolley is adapted to move along the length direction of the welding track.

[0026] Since the welding trolley assembly includes the welding track and has the same effects as the welding track, its beneficial effects will not be elaborated here. BRIEF DESCRIPTION OF THE DRAWINGS

[0040] With the development of the steel structure industry, the types of steel components are increasing. To meet the needs of building shapes, many steel components need to be processed into arc-shaped bends. However, there are many difficulties in the production process of such steel components, and one of them is the welding of arc-shaped welds. In the steel structure processing base, the most commonly used welding methods are CO 2 gas shielded arc welding and submerged arc welding. Among them, CO 2 gas shielded arc welding is a manual welding method with the advantages of flexible welding and reliable quality. However, the welding efficiency is significantly insufficient and cannot meet the welding production requirements of steel components. Submerged arc welding is an automatic welding method that relies on submerged arc welding equipment to fill and cover the groove. It has the advantages of stable weld quality, excellent forming, and outstanding efficiency. However, the trolley submerged arc welding can generally only be used for welding common straight welds. For some arc-shaped welds, the track position needs to be continuously adjusted during welding for segmented welding, resulting in too many weld butt joints, unstable forming, and a greater impact on welding efficiency.

[0041] The following will describe the embodiments of the present invention in conjunction with Figures 1 to 6 .

[0042] According to an embodiment of the present invention, on the one hand, a welding track is provided, which is arc-shaped and used to guide the traveling route of the welding trolley 8. The welding track includes:

[0043] A first arc-shaped backing plate 1 and a second arc-shaped backing plate 2, arranged in parallel;

[0044] A first limiting strip 3, fixedly connected to the upper end surface of the first arc-shaped backing plate 1, and the radian of the first limiting strip 3 is adapted to the radian of the first arc-shaped backing plate 1;

[0045] A second limiting strip 4, fixedly connected to the upper end surface of the second arc-shaped backing plate 2, and the radian of the second limiting strip 4 is adapted to the radian of the second arc-shaped backing plate 2. The first limiting strip 3 and the second limiting strip 4 are adapted to abut against the wheels 81 of the welding trolley 8 to restrict the rolling direction of the wheels 81.

[0046] The welding track provided in this embodiment restricts the rolling direction of the wheels 81 through the first limiting strip 3 and the second limiting strip 4 to guide the traveling route of the welding trolley 8, so that the welding trolley 8 moves along the arc-shaped welding track and performs curve welding, thereby avoiding continuously adjusting the track position for segmented welding during welding, which is beneficial to reducing the number of weld butt joints and improving the forming stability and welding efficiency of steel components.

[0047] Specifically, the planes where the first arc-shaped backing plate 1 and the second arc-shaped backing plate 2 are located are in the same horizontal plane. The first arc-shaped backing plate 1 extends longitudinally in the horizontal direction and is arc-shaped along its length direction. The second arc-shaped backing plate 2 also extends longitudinally in the horizontal direction and is arc-shaped along its length direction. There is a spacing between the first arc-shaped backing plate 1 and the second arc-shaped backing plate 2 and they are configured to be arranged in parallel. The first limiting strip 3 is fixedly connected to the upper end surface of the first arc-shaped backing plate 1 and extends along the length direction of the first arc-shaped backing plate 1. The second limiting strip 4 is fixedly connected to the upper end surface of the second arc-shaped backing plate 2 and extends along the length direction of the second arc-shaped backing plate 2, so that the welding track is configured to be arc-shaped.

[0048] The welding carriage 8 has a plurality of wheels 81. The welding carriage 8 is placed above the welding track. The plurality of wheels 81 roll on the upper end surfaces of the first arc-shaped backing plate 1 and the second arc-shaped backing plate 2 respectively. And under the abutting and restraining action of the first limiting strip 3 and the second limiting strip 4, the wheels 81 roll along the length direction of the welding track, so as to realize the movement of the welding carriage 8 along the arc-shaped welding track and continuously weld the arc-shaped welds of the steel members, without repeatedly adjusting the position of the track. The operation is convenient and the practicability is strong. It is especially suitable for batch welding of longitudinal seams of pipes with the same curvature, which is beneficial to improving the production efficiency and appearance of steel members. When the curvature of the arc-shaped groove of the steel member is relatively small, the welding track can effectively guide the welding carriage 8 to travel along the required route, thus avoiding the problem that in the related art, a general welding carriage needs to repeatedly adjust the position of the track during welding for segmented welding, resulting in too many weld joints, unstable forming and reduced welding efficiency; and compared with the welding method of CO 2 gas shielded welding in the related art, while ensuring the welding quality, it also has higher welding efficiency and can meet the production requirements.

[0049] In some embodiments, as shown in Figures 1 to 6 the first limiting strip 3 includes an arc-shaped round rod; the second limiting strip 4 includes an arc-shaped round rod.

[0050] Specifically, the first limiting strip 3 includes an arc-shaped round rod, an arc-shaped square rod, an arc-shaped round tube, an arc-shaped square tube; the second limiting strip 4 includes an arc-shaped round rod, an arc-shaped square rod, an arc-shaped round tube, an arc-shaped square tube. As a feasible implementation form, the first arc-shaped backing plate 1 and the second arc-shaped backing plate 2 are made of steel backing or waste steel plates. The first limiting strip 3 and the second limiting strip 4 are made of deformed steel bars or plain round steel bars and are electrically welded to the first arc-shaped backing plate 1 and the second arc-shaped backing plate 2 respectively by welding electrodes. The welding track can be made of processing waste, with low cost and easy to popularize and apply.

[0051] In some embodiments, as shown in Figures 1 to 6As shown, the widths of the first arc-shaped backing plate 1 and the second arc-shaped backing plate 2 are both H, where 15 mm ≤ H ≤ 45 mm.

[0052] For the welding track provided in this embodiment, by making the widths of the first arc-shaped backing plate 1 and the second arc-shaped backing plate 2 greater than or equal to 15 millimeters and less than or equal to 45 millimeters, it is possible to avoid an increase in the cost of the welding track when the width is too large, and to avoid a situation where the width is too small, which may affect the stability of the welding track when placed on the ground or the surface of the workbench.

[0053] Specifically, as a feasible implementation form, the heights of the first arc-shaped backing plate 1 and the second arc-shaped backing plate 2 are both 6 millimeters, and the widths of the first arc-shaped backing plate 1 and the second arc-shaped backing plate 2 are both 30 millimeters.

[0054] In some embodiments, in combination with Figures 1 to 6 As shown, the lengths of the first arc-shaped backing plate 1 and the second arc-shaped backing plate 2 are both S, where 4000 mm ≤ S ≤ 6000 mm.

[0055] For the welding track provided in this embodiment, by making the lengths of the first arc-shaped backing plate 1 and the second arc-shaped backing plate 2 greater than or equal to 4000 millimeters and less than or equal to 6000 millimeters, it is possible to avoid an increase in the manufacturing difficulty due to an overly long welding track, and to avoid a situation where the welding track is too short, which requires intermittent movement of the welding track position, resulting in a decrease in welding efficiency.

[0056] Specifically, the numbers of the first arc-shaped backing plate 1 and the second arc-shaped backing plate 2 each include at least one. Multiple first arc-shaped backing plates 1 and multiple second arc-shaped backing plates 2 can be spliced together according to the actual required length. Moreover, the length of the first limiting strip 3 is adapted to the length of the first arc-shaped backing plate 1, and the length of the second limiting strip 4 is adapted to the length of the second arc-shaped backing plate 2.

[0057] In some embodiments, in combination with Figures 1 to 6 As shown, the welding track further includes a first limiting block 6 and a second limiting block 7. The first limiting block 6 is fixedly connected to the first arc-shaped backing plate 1 and abuts against the outer peripheral wall of the first limiting strip 3 to form a limit for the movement of the first limiting strip 3 relative to the first arc-shaped backing plate 1 along the radial direction of the welding track; the second limiting block 7 is fixedly connected to the second arc-shaped backing plate 2 and abuts against the outer peripheral wall of the second limiting strip 4 to form a limit for the movement of the second limiting strip 4 relative to the second arc-shaped backing plate 2 along the radial direction of the welding track.

[0058] For the welding track provided in this embodiment, the outer peripheral wall of the first limiting strip 3 is limited by the first limiting block 6, thereby improving the connection stability between the first limiting strip 3 and the first arc-shaped backing plate 1; and the outer peripheral wall of the second limiting strip 4 is limited by the second limiting block 7, thereby improving the connection stability between the second limiting strip 4 and the second arc-shaped backing plate 2.

[0059] Specifically, the number of the first limiting blocks 6 includes a plurality, and the plurality of first limiting blocks 6 are spaced apart along the length direction of the first limiting strip 3. As a feasible implementation form, the bottom surface of the first limiting block 6 is fixedly connected to the upper end surface of the first arc-shaped backing plate 1. A partial area of the side surface of the first limiting block 6 facing away from the first arc-shaped backing plate 1 is recessed to form a groove. The groove penetrates the first limiting block along the length direction of the first arc-shaped backing plate 1. The cross-sectional dimension of the groove is adapted to the cross-sectional dimension of the first limiting strip 3, so as to be suitable for placing a partial area of the first limiting strip 3 in the groove. The first limiting strip 3 is fixedly connected to the first limiting block 6, so as to be suitable for the first limiting block 6 to limit the movement of the first limiting strip 3 in the radial direction of the welding track. As an additional implementation form, the plurality of first limiting blocks 6 are respectively arranged on both sides of the first limiting strip 3 along its length direction. The bottom surface of the first limiting block 6 is fixedly connected to the first arc-shaped backing plate 1, and one side of the first limiting block 6 close to the first limiting strip 3 is fixedly connected to the outer peripheral wall of the first limiting strip 3, thereby limiting the movement of the first limiting strip 3 in the radial direction of the welding track.

[0060] The number of the second limiting blocks 7 includes a plurality, and the plurality of second limiting blocks 7 are spaced apart along the length direction of the second limiting strip. As a feasible implementation form, the bottom surface of the second limiting block 7 is fixedly connected to the upper end surface of the first arc-shaped backing plate 1. A partial area of the side surface of the second limiting block 7 facing away from the second arc-shaped backing plate 2 is recessed to form a groove. The groove penetrates the first limiting block along the length direction of the second arc-shaped backing plate 2. The cross-sectional dimension of the groove is adapted to the cross-sectional dimension of the second limiting strip 4, so as to be suitable for placing a partial area of the second limiting strip 4 in the groove. The second limiting strip 4 is fixedly connected to the second limiting block 7, so as to be suitable for the second limiting block 7 to limit the movement of the second limiting strip 4 in the radial direction of the welding track. As an additional implementation form, the plurality of second limiting blocks 7 are respectively arranged on both sides of the second limiting strip 4 along its length direction. The bottom surface of the second limiting block 7 is fixedly connected to the first arc-shaped backing plate 1, and one side of the second limiting block 7 close to the second limiting strip 4 is fixedly connected to the outer peripheral wall of the second limiting strip 4, thereby limiting the movement of the second limiting strip 4 in the radial direction of the welding track.

[0061] In some embodiments, as shown in Figures 1 to 6 the welding track further includes a connecting member 5 disposed between the first arc-shaped backing plate 1 and the second arc-shaped backing plate 2. One end of the connecting member 5 is fixedly connected to the first arc-shaped backing plate 1, and the other end is fixedly connected to the second arc-shaped backing plate 2.

[0062] For the welding track provided in this embodiment, by fixedly connecting the connecting member 5 between the first arc-shaped backing plate 1 and the second arc-shaped backing plate 2, the overall stability of the welding track is enhanced.

[0063] Specifically, one end of the connecting member 5 along its length direction is fixedly connected to the first arc-shaped backing plate 1, and the other end is fixedly connected to the second arc-shaped backing plate 2. Preferably, the connecting member 5, the first arc-shaped backing plate 1, and the second arc-shaped backing plate 2 are located on the same horizontal plane.

[0064] In some embodiments, as shown in Figures 1 to 6 the number of the connecting members 5 includes a plurality. Along the length direction of the welding track, the spacing between two adjacent connecting members 5 is L, where 500 mm ≤ L ≤ 800 mm.

[0065] For the welding track provided in this embodiment, by arranging a plurality of connecting members 5 and making the plurality of connecting members 5 be spaced apart along the length direction of the welding track at intervals of 500 millimeters to 800 millimeters, it is beneficial to further enhance the overall stability of the welding track.

[0066] In some embodiments, as shown in Figures 1 to 6 the connecting member 5 includes a flat plate.

[0067] Specifically, the connecting member 5 includes a flat plate, a flat rod, an arc-shaped plate, and an arc-shaped rod. The welding track provided in this embodiment has a simple structure and is easy to manufacture.

[0068] In some embodiments, as shown in Figures 1 to 6 the length of the connecting member 5 is 350 millimeters.

[0069] For the welding track provided in this embodiment, the length of the connecting member 5 includes multiple specifications to be suitable for fixedly connecting the first limiting strip 3 and the second limiting strip 4 with different spacing intervals, so as to be applicable to welding trolleys 8 of different specifications, which is beneficial to improving the applicability of the welding track.

[0070] Specifically, the spacing interval between the first limiting strip 3 and the second limiting strip 4 is adapted to the spacing interval between the two side wheels 81 of the welding trolley 8. The length of the connecting member 5 includes 250 millimeters to 500 millimeters. When the length direction of the connecting member 5 is parallel to the radial direction of the welding track, by selecting connecting members 5 with different lengths, the spacing interval between the first limiting strip 3 and the second limiting strip 4 is adjusted, so as to be adapted to welding trolleys 8 of different specifications. As a feasible implementation form, the length of the connecting member 5 is 350 millimeters to be adapted to the spacing interval between the two side wheels 81 of a certain specification of welding trolley 8.

[0071] According to an embodiment of the present invention, on the other hand, a welding trolley assembly is further provided, including:

[0072] a welding trolley 8;

[0074] Specifically, the welding carriage 8 includes a plurality of wheels 81, a base 83, and at least one welding torch 82. The plurality of wheels 81 are respectively arranged on both sides of the base 83 and are rotatably connected to the base 83. The welding torch 82 is arranged on the base 83. It should be noted that the welding carriage 8 belongs to the prior art in this field and will not be elaborated here. A circumferential groove is formed by partial depression of the outer peripheral wall of the wheel 81. Part of the first limiting strip 3 or the second limiting strip 4 is located in the circumferential groove. The welding carriage 8 is installed on the welding track through the wheels 81 so as to make the inner wall of the circumferential groove abut against the outer peripheral wall of the first limiting strip 3 or the second limiting strip 4, thereby enabling the first limiting strip 3 or the second limiting strip 4 to restrict the rolling direction of the wheel 81, guiding the welding carriage 8 to move along the length direction of the welding track, and further realizing curved welding.

[0075] Taking the example that the first arc-shaped backing plate 1 and the second arc-shaped backing plate 2 are made of backing plate waste materials, the connecting piece 5 is made of short backing plates, and the first limiting strip 3 and the second limiting strip 4 are made of steel bar waste materials. When manufacturing the welding track, first draw the backing plate ground line and the steel bar ground line according to the curvature of the weld line to be welded; splice the backing plate waste materials and the steel bar waste materials appropriately to obtain a sufficient length to be processed; first place the backing plate on the ground line, and gradually form the backing plate along the ground line by means of local thermal forming; the steel bar is bent by multi-point bending to make it fit the ground line type; make short backing plates according to the wheel axle distance of the welding carriage 8, generally with a length of 350 mm, and configure the corresponding quantity at intervals of 500 mm to 800 mm; weld the arc-shaped welding track according to the overall 1:1 ground line size of the track, and fix the contact points by spot welding. During the electric welding process, it is advisable to first select some positions at the ends and in the middle for spot welding, then place the welding carriage 8 on the track, check its running ability, and after the size adjustment is in place, perform densified spot welding on the track to ensure that it has sufficient anti-deformation ability during cyclic use.

[0076] Obviously, the above embodiments are only examples for clear illustration and not limitations on the implementation manners. Although the embodiments of the present invention are described in conjunction with the drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations all fall within the scope defined by the present invention.
