Description

Technical Field

[0001] The utility model relates to the technical field of steel plate welding, in particular to a steel plate welding auxiliary device. Background Art

[0002] In the prior art, a welding frame is required when welding H-beams. The existing welding frame includes a base plate, on which two rows of flange support plates are fixed, and a web support plate is arranged between two opposite flange support plates in the two rows. When in use, the H-beam can be assembled on the welding frame.

[0003] In the above operation, a wedge is needed for auxiliary operation. The wedge is generally set in a triangular shape. After the H-beam is assembled, the wedge is wedged between the H-beam flange plate and the flange backing plate to clamp the H-beam and prevent the H-beam from loosening during welding.

[0004] However, after the H-beam is welded, workers need to manually remove the wedges. Since the wedges are very tight between the H-beam flange plate and the flange template, it is very troublesome and laborious to remove the wedges. Therefore, improvements are needed. Utility Model Content

[0005] In view of the deficiencies in the prior art, the utility model provides a steel plate welding auxiliary device, which solves the problems mentioned in the background technology.

[0006] In order to achieve the above objectives, the present invention is implemented through the following technical solutions:

[0007] A steel plate welding auxiliary device includes a plurality of triangularly arranged wedges, each of which is installed on a corresponding row of flanges on a welding frame through an auxiliary structure, close to the side of a template, an H-shaped steel is placed on the welding frame, and the longest side of the wedge is attached to one flange side of the H-shaped steel.

[0008] Specifically in the utility model, the auxiliary structure includes a slide groove opened on the side of the flange close to the template, a guide member is slidably installed in the slide groove, the back corner of the wedge iron is fixed at one end of the guide member, the guide member includes a guide rod slidably installed in the slide groove, the length of the guide rod is the same as the longest side of the wedge iron, a main smashing plate is fixed at one end of the guide rod, and a secondary smashing plate is fixed at the other end, and the main smashing plate is fixed at the back corner of the wedge iron.

[0009] Compared with the prior art, the utility model has the following beneficial effects: a worker hits the main striking plate with a hammer, and the auxiliary wedge iron is wedged into between the H-steel flange plate and the flange support plate, so the H-steel is clamped more labor-saving and conveniently; conversely, the auxiliary striking plate is hit with a hammer to separate the wedge block from between the H-steel flange plate and the flange support plate, so the wedge iron is disassembled more labor-saving and conveniently, and the utility model has a simple structure and high practicality.

[0015] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0016] like Figure 1-2 As shown, the utility model provides a steel plate welding auxiliary device, including a plurality of triangularly arranged wedges 1, each of which is installed on a corresponding row of flanges on a welding frame through an auxiliary structure, and a H-shaped steel N is placed on the welding frame, and the longest side of the wedge 1 is attached to a flange edge of the H-shaped steel N.

[0017] like Figure 3 As shown, in the utility model, the auxiliary structure includes a slide groove M-1 opened on the side of the flange template M, a guide member is slidably installed in the slide groove M-1, the back corner of the wedge iron 1 is fixed at one end of the guide member, and the guide member includes a guide rod 2 slidably installed in the slide groove M-1. The length of the guide rod 2 is the same as the longest side of the wedge iron 1, a main smashing plate 3 is fixed at one end of the guide rod 2, and a secondary smashing plate 4 is fixed at the other end, and the main smashing plate 3 is fixed at the back corner of the wedge iron 1.

[0018] like Figure 4 As shown, in order to enable the wedge 1 to move and adapt to H-shaped steels N of different widths, the slide groove M-1 is arranged in a long strip shape.

[0019] like Figure 4 As shown, in order to prevent the guide rod 2 from rotating in the slide groove M-1, the cross section of the guide rod 2 is a square.

[0020] The working principle of the utility model is described in detail below: After the H-shaped steel N is placed on the welding rack, the wedge iron 1 is pushed to move in the direction of the H-shaped steel N, and the guide rod 2 moves along the length direction of the slide groove M-1, so that the longest side of the wedge iron 1 is attached to a flange plate of the H-shaped steel N. The worker hits the main smashing plate 3 with a hammer, and the guide rod 2 moves in the slide groove M-1 without rotating, so that the wedge iron 1 is wedged between the flange plate of the H-shaped steel N and the flange template M, which is more labor-saving and convenient to clamp the H-shaped steel N. After the welding of the H-shaped steel N is completed, the auxiliary smashing plate 4 is hit with a hammer, and the guide rod 2 slides in the opposite direction in the slide groove M-1, so that the wedge block is separated from the flange plate of the H-shaped steel N and the flange support template M, and the wedge iron 1 is removed more labor-saving and conveniently. Moreover, after the wedge iron 1 is removed, the wedge iron 1 can be pushed in the reverse direction to move away from the H-shaped steel N, and the guide rod 2 moves in the opposite direction along the slide groove M-1, so that the wedge iron 1 can be retracted to the side of the flange support template M, which will not hinder the removal of the H-shaped steel N and prevent the wedge iron 1 from being lost.

[0021] Finally, the most important contribution of the utility model is that workers use hammers to hit the main striking plate 3, and the auxiliary wedge 1 is wedged between the flange plate of the H-beam N and the flange support plate M, which makes it easier and more convenient to clamp the H-beam N. Conversely, workers use hammers to hit the auxiliary striking plate 4 to detach the wedge from between the flange plate of the H-beam N and the flange support plate M, making it easier and more convenient to disassemble the wedge 1. The utility model has a simple structure and high practicality.

[0022] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
