AI Technical Summary
In the existing technology, it is difficult to effectively utilize submerged arc welding machines in the welding of steel box girders, especially in the welding of fillet welds or groove welds between the web and the top and bottom plates of the steel girder, resulting in low construction efficiency, high rework rate and labor-intensive work.
A submerged arc welding machine track bracket for steel box girder welding is designed, including a bracket structure composed of horizontal and vertical rods, which is connected by screw holes and sleeves to achieve stable support of the track and is suitable for the stable operation of the submerged arc welding machine.
It improves the construction efficiency of steel box girder welding, reduces the weld repair rate, avoids welding spatter caused by manual welding, and simplifies the subsequent grinding process.

Abstract
Description
TECHNICAL FIELD
[0001] The utility model belongs to bridge construction technical field relates to a steel box girder's welding processing, concretely relates to a kind of for steel box girder welding's submerged-arc welding machine track support. BACKGROUND
[0002] Submerged-arc welding machine needs to walk on track when construction, track is usually laid on plane, it is generally used for steel plate butt joint when steel box girder is processed, and for the butt joint of steel beam web and top and bottom plate, since weld is fillet weld or groove weld, and there is a certain height from ground, it is not easy to erect welding machine track in narrow space, therefore, manual welding is used in construction, and according to the size of groove and weld leg, multiple layers and multiple passes are welded, and there is a certain repair rate of weld, and more labor is consumed. SUMMARY
[0003] The utility model aims at above -mentioned problem, provide a kind of for steel box girder welding's submerged-arc welding machine track support, realize the joint of steel beam web and top and bottom plate with submerged-arc welding machine welding.
[0004] The technical scheme of the utility model is as follows:
[0005] A kind of for steel box girder welding's submerged-arc welding machine track support, it is characterized by including a horizontal lower cross bar, a vertical pole is welded in the middle of lower cross bar, multiple screw holes are equidistantly set on vertical pole, a sleeve is movably sleeved on vertical pole, two screw holes are provided on sleeve, two screw holes on sleeve are respectively passed through and positioned bolt is arranged, a upper cross bar is welded in the middle of sleeve, the upper cross bar is perpendicular to vertical pole and lower cross bar, and L-shaped slot is set in the bottom of the front end of upper cross bar.
[0006] The utility model has simple structure, and occupies small space, can realize the stable support of submerged-arc welding machine track, can greatly improve the efficiency of construction using submerged-arc welding, reduce weld repair rate, avoid the welding spatter caused by manual welding, reduce the workload of subsequent polishing process. BRIEF DESCRIPTION OF DRAWINGS
[0007] Figure 1 It is the structure schematic diagram of the utility model;
[0008] Figure 2 It is the use state schematic diagram of the utility model. DETAILED DESCRIPTION
[0009] As Figure 1As shown, the utility model includes a horizontally arranged lower cross bar 1, a vertical bar 2 is welded in the middle of the lower cross bar, a plurality of screw holes 3 are equidistantly provided on the vertical bar, a sleeve 4 is movably sleeved on the vertical bar, two screw holes are provided on the sleeve, the two screw holes on the sleeve are respectively aligned with the two screw holes on the vertical bar and penetrated with positioning bolts 5, an upper cross bar 6 is welded in the middle of the sleeve 4, the upper cross bar 6 is perpendicular to the vertical bar 2 and the lower cross bar 1, and an L-shaped slot 7 is provided at the bottom front end of the upper cross bar 6.
[0010] When the utility model is implemented, all the rods can be made of square steel pipes commonly used in steel structure processing plants, which are easy to manufacture.
[0011] like Figure 2 As shown, in the steel box girder processing workshop, the bottom plate 8 of the steel box girder is supported on a stand, and the two webs 9 of the steel box girder are supported on the top surfaces of the bottom plate 8 on both sides. The two sides of the bottom plate 8 protrude a certain width outside the webs 9, and the seams between the bottom edge of the webs and the top surface of the bottom plate need to be welded. A bracket of the present invention is set at a certain interval along the longitudinal direction of the outer side of the steel box girder, generally one is set every 50 cm. The lower cross bar 1 of the bracket is supported on the ground in a direction parallel to the steel box girder. According to the height of the bottom plate, two screw holes of appropriate height on the vertical rod of the bracket are selected to fix the sleeve and the vertical rod with bolts, and the L-shaped slot at the front end of the upper cross bar is clamped on the part of the bottom plate protruding to the outside of the web. The top surface of the slot is supported on the top surface of the bottom plate, and the inner side surface of the slot is pressed against the outer side surface of the side edge of the bottom plate to prevent the bracket from tilting or rotating. A submerged arc welding track 10 is installed on the upper crossbar 6 of each bracket along the longitudinal direction of the steel box girder. The welder welds the seam between the bottom plate and the web along the track, which is equivalent to welding on a flat surface, greatly improving construction efficiency. During construction, after the welder moves forward a certain distance, the brackets in the welded area at the rear can be moved to the front and rearranged, allowing for recycling and reducing bracket usage.
