Description

Technical Field

[0001] The utility model relates to the field of submerged arc welding stands, in particular to a submerged arc welding stand. Background Art

[0002] Submerged arc welding (including submerged arc cladding and electroslag cladding) is a welding method in which the arc burns under the flux layer. Its inherent advantages of stable welding quality, high welding productivity, no arc light and little smoke make it the main welding method in the production of important steel structures such as pressure vessels, pipe section manufacturing, box beams and columns.

[0003] However, a large amount of slag will remain on the workpiece, which requires subsequent processing. In most cases, it is removed manually. For portable small-scale submerged arc welding equipment, the welding location is relatively random. When welding on the spot, in addition to the shortcoming that the slag is inconvenient to remove, the slag after manual removal can only fall on the ground, causing pollution to the working environment. It is also relatively labor-intensive to clean up. For this situation, a submerged arc welding stand is provided accordingly. Utility Model Content

On the one hand, the support rods 27 can provide support for the storage box 25 above the adjusting frame 20, and on the other hand, they cooperate with the limiting slide grooves 28 to provide a limiting effect for the bracket 23 to drive the submerged arc welding mechanism to move in the adjusting frame 20. A welding device 26 is connected to one side of the bottom of the storage box 25, and a welding pipe connecting part 30 that cooperates with the storage box 25 and the welding device 26 is connected to the bracket 23. The bottom end of the welding pipe connecting part 30 is connected to a submerged arc welding end 24, and the top of the threaded column 18 is connected to a control box 29.

[0023] The No. 2 motor 17 provides operating power for the worm gear transmission mechanism 16, and under its transmission action, the threaded column 18 is rotated on the base 1, and cooperates with the limiting action of the slide rod limiting mechanism 19 on the upper side, so that the adjustment frame 20 and its attached parts and mechanisms can be further adjusted in height above the base 1.

[0024] Embodiment 2

[0025] Combined with Figure 1-4The base 1 is connected to an electric telescopic rod 4 on one side near the submerged arc welding end 24, and a bracket 5 is connected to the movable end of the electric telescopic rod 4.

[0027] During the specific implementation of the utility model, when using the submerged arc welding equipment with the stand device to weld workpieces, the workpiece, such as a plate, is placed on the ground, and the position of the stand and the corresponding mechanism in the device are adjusted so that the submerged arc welding end 24 is located above the welding point of the workpiece. During welding, the threaded shaft 21 is rotated to drive the bracket 23 and the submerged arc welding mechanism to move slowly along the welding point, thereby welding the workpieces together. After the welding is completed, the submerged arc welding end 24 is raised away from the workpiece by the rotation of the threaded column 18, and the electric telescopic rod 4 below drives the slide 7 to move along the weld to scrape off excess welding slag. The slag debris moves with the slide 7 and is pushed into the collection box 13 on the other side. When the slag stored in the collection box 13 needs to be processed, the collection box 13 is partially released from the base 1 and then dumped.
