When welding the other side, the crane hook can be used to hook and turn the direction, making it safe, convenient, and fast. Furthermore, this utility model's jig allows for the simultaneous welding of two H-beam components, further improving processing efficiency.

Description

Technical Field

[0001] This utility model relates to the field of steel component welding jig technology, and in particular to a double welding jig for welding H-beams with a gantry welding machine. Background Technology

[0002] In steel structure production workshops, a large number of H-beam steel components are frequently produced. These components are widely used in steel structure buildings and are used in large quantities, so they are also produced in large quantities in the workshop. At the same time, these components are relatively long and are usually welded using gantry welding. The previous gantry welding brackets were not made in a standardized manner, and the brackets themselves were prone to deformation. When the components were placed on them for welding, they were also prone to deformation. Moreover, the previous welding brackets had certain safety hazards. Therefore, it is necessary to design a jig that is more conducive to welding H-beam steel with gantry welding machines. Utility Model Content

[0003] The purpose of this utility model is to address the above-mentioned situation by providing a double welding jig for welding H-beams with a portal welding machine. The double welding jig has a simple structural design, can simultaneously weld two sets of H-beam components, has high efficiency, and the workpiece will not be deformed.

[0004] The specific solution of this utility model is: a double welding jig for welding H-beams with a gantry welding machine, having a chassis, on which a left jig and a right jig are symmetrically arranged, and a pedestrian passage is provided between the left jig and the right jig. The left jig and the right jig have the same structure, each including a supporting column and a V-shaped bracket. The V-shaped bracket is set at a 90° V-angle, one side of the V-shaped bracket is connected to the edge of the pedestrian passage, and the other side is supported and connected by the supporting column.

[0005] Furthermore, the V-shaped bracket described in this utility model is composed of several right-angled V-shaped rods. All the right-angled V-shaped rods are arranged in a row longitudinally, and the V-shaped included angles of the right-angled V-shaped rods are arranged on the same straight line. A supporting column is provided for each right-angled V-shaped rod. The upper end of the supporting column is welded to the corresponding right-angled V-shaped rod, and the lower end of the supporting column is welded to the chassis.

[0006] Furthermore, the right-angled V-shaped rod described in this utility model is a right-angled structure assembled and welded from a long steel pipe and a short steel pipe, wherein the short steel pipe is arranged on the inner side and the long steel pipe is arranged on the outer side.

[0007] Furthermore, the pedestrian walkway described in this utility model includes a gate-shaped support, which is arranged along the V-shaped support. A walking steel plate is installed on the gate-shaped support along its length, and the walking steel plate is provided with anti-slip patterns.

[0008] Furthermore, the chassis described in this utility model is a rectangular shape assembled and welded from square steel pipes.

[0009] After unique design and manufacturing, this utility model connects two right-angled V-shaped bars with a 2-meter interval between them. After being firmly welded, a walking steel plate with anti-slip pattern is laid in the middle to serve as a safe passage for workers. When the assembled H-beams are transported to the 90-degree right-angled V-shaped bars by a crane, they can be welded. When welding the other side, the crane hook can be used to hook the H-beams and lift them gently to turn them over or change direction, which is safe, convenient and quick. At the same time, the jig in this utility model can also enable the simultaneous welding of two H-beam components, further improving processing efficiency. Attached Figure Description
