This device converts the fillet welds of the I-beams into flat welds and then performs the welding via a submerged arc welding vehicle, thereby solving the problems of poor weld appearance quality and low welding efficiency in semi-automatic mixed gas shielded welding.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0009] Furthermore, the welding torch support assembly includes a vertical connecting rod, a horizontal connecting rod, and a welding torch connecting rod. One end of the vertical connecting rod and one end of the welding torch connecting rod are respectively vertically connected to the two ends of the horizontal connecting rod, and the vertical connecting rod and the welding torch connecting rod are spaced apart and opposite to each other. The other end of the vertical connecting rod is connected to the submerged arc welding vehicle, and the other end of the welding torch connecting rod is connected to the welding torch.

[0010] Furthermore, both the vertical connecting rod and the horizontal connecting rod are telescopic rods.

Detailed Implementation

[0020] The embodiments of this utility model will be described in detail below with reference to the accompanying drawings, so as to better understand the purpose, features and advantages of this utility model. It should be understood that the embodiments shown in the drawings are not intended to limit the scope of this utility model, but are only for illustrating the essential spirit of the technical solution of this utility model.

[0021] like Figure 1-2 As shown. This utility model discloses a welding device for submerged arc welding of large non-standard I-beams, including a welding frame body 4, a submerged arc welding carriage 1, a linear slide 2, and a welding torch support assembly 3. The welding frame body 4 has an inclined angle frame for adjusting the fillet weld of the I-beam 5 to a flat welding position and supporting the I-beam 5. The linear slide 2 is set on the welding frame body 4 on one side of the inclined angle frame. The submerged arc welding carriage 1 is slidably connected to the linear slide 2. One end of the welding torch support assembly 3 is connected to the submerged arc welding carriage 1, and the other end is connected to the welding torch of the submerged arc welding carriage 1. The welding torch is located above the inclined angle frame.

[0022] Specifically, the linear slide 2 includes a base plate and linear guide rails. A pair of spaced-apart linear guide rails are mounted on the base plate, which is located on the welding frame body 4. The bottom of the submerged arc welding carriage 1 has traveling wheels, which are respectively embedded in a pair of linear guide rails. The outer circumference of the traveling wheels has grooves, and the upper end of the linear guide rails has protrusions that match the grooves.

[0023] Preferably, the grooves and protrusions have triangular cross-sections.

[0024] The I-beam 5 is continuously hoisted and flipped four times before being placed on the inclined angle frame, converting the four corner welds of the I-beam 5 into flat welds. Meanwhile, the submerged arc welding vehicle 1 drives the welding gun support assembly 3 to move along the linear slide table 2, and the welding gun completes the welding operation in sequence.

[0025] Furthermore, the tilting frame includes an L-shaped support platform, with several L-shaped support platforms arranged in a linearly spaced array, and the I-beam 5 located on the L-shaped support platform. The end faces of a pair of vertical beams of the I-beam 5 are attached to one side surface of the L-shaped support platform, and the outer side of one of the vertical beams is attached to the other side surface of the L-shaped support platform, so that the connecting weld between the horizontal beam and the vertical beam of the I-beam 5 forms a flat weld angle.

[0026] Furthermore, the welding frame body 4 also includes a support base frame, the linear slide 2 is located on the upper side of the support base frame, the L-shaped support platform array is set on the support base frame, the bottom of the L-shaped support platform is fixedly connected to the support base frame, and the two ends of the L-shaped support platform extend in an inclined direction away from the support base frame.

[0027] Furthermore, to improve the load-bearing capacity of the tilting frame, the tilting frame also includes side support beams 403. The number of side support beams 403 is the same as the number of L-shaped support platforms. One end of each side support beam 403 is connected to the end of the L-shaped support platform away from the submerged arc welding vehicle 1, and the other end is connected to the support base. Each side support beam 403, one side of the L-shaped support platform, and the support base can form a triangular structure, and the middle of each side support beam 403 is connected by a transverse beam 405.

[0028] Furthermore, the welding torch support assembly 3 includes a vertical connecting rod 302, a horizontal connecting rod 301, and a welding torch connecting rod 303. One end of the vertical connecting rod 302 and one end of the welding torch connecting rod 303 are respectively vertically connected to the two ends of the horizontal connecting rod 301, and the vertical connecting rod 302 and the welding torch connecting rod 303 are spaced apart and opposite to each other. The other end of the vertical connecting rod 302 is connected to the upper surface of the submerged arc welding vehicle 1 and is perpendicular to the submerged arc welding vehicle. The welding torch connecting rod 303 is spaced parallel to the vertical connecting rod 302, and the other end of the welding torch connecting rod 303 is connected to the welding torch.

[0029] Furthermore, considering the relatively long flange protrusion of the I-beam 5, the welding torch support assembly 3 can be adjusted in both horizontal and vertical directions. Both the vertical connecting rod 302 and the horizontal connecting rod 301 are telescopic rods. Adjusting these telescopic rods allows for adjustment of the welding torch position, enabling one-time forming of long fillet welds.

[0030] As a preferred option, the telescopic rod is an electric push rod.

[0031] As a preferred option, the telescopic rod is a manual telescopic rod. When it is a manual telescopic rod, both the vertical connecting rod 302 and the horizontal connecting rod 301 include a sleeve and a connecting rod. The connecting rod is slidably nested in the sleeve. Both the sleeve and the connecting rod have radial through holes arranged in their axial directions. The length of the sleeve and the connecting rod can be adjusted by inserting pins into different through holes.

[0032] Furthermore, the L-shaped support platform includes a first support beam 401 and a second support beam 402. The length of the first support beam 401 is shorter than the length of the second support beam 402. One end of the first support beam 401 is connected to one end of the second support beam 402, forming a corner. The other end of the first support beam 401 extends inclined towards the linear slide 2. One end of the second support beam 402 is connected to the support base, and the other end extends inclined away from the linear slide 2. The other end of the second support beam 402 is connected to one end of a side support beam 403, and the other end of the side support beam 403 is connected to the support base. When the I-beam 5 is placed, the outer surface of one vertical beam of the I-beam 5 is attached to the upper surface of the first support beam 401, and the ends of the pair of vertical beams of the I-beam 5 are attached to the upper surface of the second support beam 402.

[0033] Furthermore, the first support beam 401 and the second support beam 402 are vertically connected to form a right angle, the angle between the second support beam 402 and the support base is 35-45 degrees, preferably 40 degrees, and the side support beam 403 is vertically connected to the support base.

[0034] Furthermore, the welding frame body 4 also includes a vertical base frame, which is set on the upper side of the support base frame, and the linear slide 2 is set on the vertical base frame. The vertical base frame is set along the axial direction of the linear slide 2 to support the linear slide 2. The vertical base frame can indirectly raise the height of the submerged arc welding carriage 1 so that it is basically consistent with the height of the I-beam 5, which facilitates the movement and welding of the submerged arc welding carriage 1.

[0035] Furthermore, the supporting base frame includes a first horizontal beam 406 and a second horizontal beam 407, with at least one pair of first horizontal beams 406 spaced apart and at least one pair of second horizontal beams 407 spaced apart and longitudinally and transversely connected to the first horizontal beams 406.

[0036] As a preferred embodiment, the number of first horizontal beams 406 can be the same as the number of L-shaped support platforms and side support beams 403, and each L-shaped support platform and side support beam 403 can be connected to a first horizontal beam 406.

[0037] Furthermore, the vertical base frame includes at least one pair of vertical support beams 404, which are arranged at relative intervals along the axial direction of the linear slide 2. The linear slide 2 is disposed on the vertical support beams 404, one end of the vertical support beams 404 is vertically connected to one end of the first horizontal beam 406, and one end of the side support beams 403 is vertically connected to the other end of the first horizontal beam 406.

[0038] As a preferred embodiment, the number of vertical support beams 404 is the same as the number of first horizontal beams 406, and a vertical support beam 404 is provided on one side of the upper end of each first horizontal beam 406. A row of vertical support beams 404 arranged in an array at intervals forms a vertical base frame.

[0039] Alternatively, the number of vertical support beams 404 is twice the number of the first horizontal beams 406. In this case, the vertical support beams 404 are arranged in two rows along the radial spacing of the linear slide, and each row is arranged along the axial spacing of the linear slide. The vertical support beams 404 arranged along the radial spacing of the linear slide are set in the axial direction of the first horizontal beams 406, and the two rows of vertical support beams 404 form a vertical base frame.

[0040] In this invention, the length of the second horizontal beam 407 is preferably 12m, and the length of the linear slide 2 is preferably 12m, which can meet the requirement of supporting the I-beam 5 with a length of 8-10m.

[0041] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
