Description

Technical Field

[0001] The utility model belongs to the technical field of steel beam welding, in particular to a steel beam butt welding device. Background Art

[0002] During the construction of offshore modules and other steel structures, the structural framework typically involves a large number of H-beams and composite beams welded together. Specifically, H-beams of varying sizes and types need to be welded to the main structure of the composite beams.

[0003] During the welding process, the operator is required to push and align a certain length of H-beam to the welding position, and then weld the H-beam to the composite beam at the welding position. However, in actual work, due to the length and weight of the H-beam itself, it is difficult to accurately weld the H-beam to the welding position during welding. Therefore, the posture of the H-beam must be continuously corrected during the welding process to ensure that the welding end of the H-beam is accurately aligned with the welding position to ensure welding accuracy.

[0004] However, it is actually very difficult to correct the posture of the H-beam. First of all, the H-beam itself has a certain weight and length, and the controllability of the steel is very poor. As a result, when the operator pushes the H-beam during welding, the H-beam can easily deviate from the pre-aligned track, and it is also difficult to correct it afterwards. Specifically, due to the certain length of the H-beam, it is difficult to adjust the posture, especially after fine-tuning. After the end of the H-beam is aligned in time, the body of the steel cannot ensure that the end of the steel is in seamless contact with the welded composite beam (as long as the posture of the steel is tilted, the end of the steel cannot ensure seamless contact with the required welded composite beam).

[0030] 1. During operation, the H-shaped steel material is loaded onto the bottom of the material and supported on the pushing rollers. The rolling pushing method of the rollers is used to reduce the pushing resistance. At the same time, the push cylinders on both sides are working, and the drive arms on both sides are close to each other until the clamping wheels contact the two sides of the H-shaped steel material.

An I-shaped connecting plate 2 is welded and fixedly connected between the bottoms of the jig frames 1. Connecting plates 2 are provided with a plurality of roller holes 21, into which push rollers 3 are rotatably mounted.

[0044] At the same time, the tooling frame 1 is respectively equipped with a clamping wheel assembly 4 for clamping the steel beam. The clamping wheel assembly 4 includes a plurality of clamping wheels 44 slidably assembled on the tooling frame 1 (specifically, the clamping wheel 44 includes a wheel seat 42 and a wheel body rotatably connected to the wheel seat; a slide rod 421 is fixedly connected to the wheel seat 42).

In addition, each T-shaped seat 5 is connected to the horizontal adjustment mechanism via two height adjustment structures spaced apart on the left and right sides.

[0050] During welding, the horizontal adjustment mechanism adjusts the beam left and right, while the height adjustment mechanism adjusts the relative height of the beam to the welded steel frame. This method allows the beam to be aligned with the welded steel frame in a labor-saving and easy-to-adjust manner.

[0051] Specifically, the height adjustment structure includes a sliding screw 51 slidably connected to the T-shaped seat 5; the bottom of the sliding screw 51 is fixedly connected to the horizontal adjustment mechanism, and the upper end of the sliding screw 51 is threadedly connected to a support nut 511 supported on the bottom of the T-shaped seat 5.

[0056] The specific structure of the screw structure is as follows:

[0057] The screw structure includes a screw 81 threadedly connected to the rear slide 6, and the screw 81 is rotatably connected to the two ends of the fixed base 7 (according to the existing method, bearings for rotatably connecting the screw 81 are installed on the fixed base 7); at the same time, according to the existing method, the screw 81 is installed with a screw motor 8, and the screw motor 8 is fixedly installed on the fixed base 7.
