Detailed Implementation

[0022] To provide a clearer understanding of the technical features, objectives, and effects of this utility model, the specific embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0023] like Figures 1-3 As shown, the steel structure welding device includes a gantry 1, a welding torch mechanism 2 slidably mounted on the gantry 1, a support base plate 3 mounted below the welding torch mechanism 2, and an L-shaped bracket mounted on the support base plate 3. The device is characterized in that it further includes an adjustable pad block mechanism 6 and a pressure block mechanism 7 mounted on the L-shaped bracket.

[0024] The L-shaped bracket includes a side inclined plate 4 and two support rods 5 located at the lower part of the side inclined plate 4. Adjustable pad block mechanisms 6 are respectively provided on the two support rods 5.

[0025] The pressing mechanism 7 includes a fixed block 71 detachably connected to the upper part of the support rod 5, a locking rod 72 connected to the fixed block 71, a pressing body 73 connected to the lower end of the locking rod 72, and a driving member connected to the upper end of the locking rod 72.

[0026] This steel structure welding device includes an adjustable pad mechanism 6 mounted on a support rod 5. During welding, the adjustable pad mechanism 6 stably supports the web plate. Then, a pressure block mechanism 7 clamps the steel structure to be welded, followed by welding using a welding torch mechanism 2. This steel structure welding device provides stable support for the web plate of the steel structure to be welded, preventing web plate displacement during welding and ensuring better welding results.

[0027] The fixing block 71 is located on one side of the support rod 5, the locking rod 72 is a screw, and the driving component is a handwheel 74 mounted on the screw. In this embodiment, the two support rods 5 are located at both ends of the side inclined plate 4 in an L-shape with the inclined plate, the fixing block 71 is located on one side of the support rod 5, and the two fixing blocks 71 are arranged facing each other. By rotating the handwheel 74, the screw drives the pressure block body 73 to press the wing plate.

[0028] In actual production, the position of the web plate relative to the wing plate will vary depending on the specific specifications. Therefore, the adjustable pad mechanism 6 is used to adjust the position of the web plate relative to the wing plate. Therefore, in this embodiment, the adjustable pad mechanism 6 is connected to the support rod 5 and can extend and retract relative to the support rod 5, and the extension and retraction direction is towards the inside of the L-shaped bracket.

[0029] The adjustable pad block mechanism 6 includes an adjusting beam 57 that can extend and retract along the support rod 5, a fixed support block 52 disposed on the adjusting beam 57, a slider 53 that is slidably disposed on the adjusting beam 57, and a locking mechanism disposed on the slider 53 for locking the slider 53 to a position of the adjusting beam 57.

[0030] The support rod 5 is provided with a storage groove 51 that is adapted to the adjusting beam 57. An adjusting rod 61 is provided at the bottom of the storage groove 51. One end of the adjusting rod 61 is connected to the adjusting beam 57, and the other end is provided with an adjusting knob 62. By turning the adjusting knob 62, the adjusting rod 61 is adjusted, thereby driving the adjusting beam 57 to extend or retract in the direction relative to the side inclined plate 4.

[0031] Considering the width specifications of the web, the locking mechanism includes a locking hole provided on the slider 53, and a locking screw 54 passes through the locking hole. By adjusting the position of the slider 53, stable support for webs of different width specifications can be achieved.
