Description

Technical Field

[0001] The utility model relates to the technical field of construction engineering construction, in particular to a processing platform for steel pipe columns. Background Art

[0002] Steel trestles and steel pipe supports are common techniques in road and bridge engineering construction. They have the advantages of good stress performance, convenient connection, and reusable. However, they are also the parts most prone to safety accidents during construction. The steel pipe columns are usually vertically connected by flanges or welding. To enhance the stability and stiffness of the columns, horizontal connection is also required. And the vertical connection usually needs to weld the ear plates on the steel pipe columns. These welding operations are often carried out by workers directly welding the ear plates at the corresponding positions on the steel pipe columns. This approach has the following problems: (1) The surface of the steel pipe lacks suitable positioning marks, making it difficult to ensure the accurate positions of multiple ear plates on the same column and the relative consistency of the ear plate positions on multiple columns during welding; (2) There is no support during welding operations, and the ear plates may be welded at uneven angles. Some factories will set up a construction platform beside the columns to allow workers to rely on the platform to assist welding to improve accuracy, but this approach also has the following problems: (1) The arc-shaped surface of the steel pipe is difficult to position, and it is inconvenient to determine the welding interval angle on the steel pipe.

The change or adjustment of their relative relationship, without substantial change in the technical content, should also be regarded as the scope in which the present utility model can be implemented.

[0030] As Figure 1-2 shown, an embodiment of the present utility model provides a steel pipe column processing platform, including: a base 100, the base 100 has a rectangular structure, and a plurality of positioning ear plates 110 are arranged at intervals on the base 100 for supporting the steel pipe to be processed. The positioning ear plates 110 are fixed to the base 100 by bolts and can be disassembled, adjusted in position and then connected when the length of the steel pipe column needs to be adjusted; two positioning brackets 200 are respectively arranged on the opposite sides of the base 100 for positioning the two ends of the steel pipe to be processed; a plurality of positioning platforms 300 are arranged at intervals on one side of the base 100 for positioning the ear plates to be processed, and the spacing of the positioning platforms 300 is set according to the positions of the ear plates to be processed.

[0031] In the embodiment of the present utility model, steel pipe columns of different lengths are processed by adjusting the positions of the positioning brackets 200, and at the same time, the positioning platforms 300 can adjust the welding positions of the ear plates, which not only improves the processing accuracy and quality, but also effectively reduces the time for manually positioning the ear plates 110.

[0032] As Figure 3As shown, in the embodiment of the present utility model, the contact end of the positioning ear plate 110 with the steel pipe is in an arc structure to better fit the circular arc surface of the steel pipe, improve the support stability. At the same time, in order to improve the support effect, in this embodiment, two positioning ear plates 110 are taken as a group, and three or four groups are respectively arranged on the base 100, and equal distances are set between each group to support multiple parts of the steel pipe.

Specifically, the rolling device 400 includes a roller 410 and a driving motor 420 for driving the roller 410 to rotate. Of course, two rolling devices 400 can also be provided to facilitate the rotation of the steel pipe.

[0036] The working process of the embodiment of the present utility model is as follows:

[0037] The first step: First, fix the two flange plates on the positioning flanges of the two positioning platforms 300 with pin shafts respectively;

[0038] The second step: Lift the steel pipe onto the base 100. After the position is determined by the positioning ear plate 110, weld the steel pipe and the flange;

[0039] The third step: Place the ear plate to be welded on the positioning platform 300, fix the ear plate with the pin shaft on the top plate 320 of the positioning platform 300, and weld the ear plate after determining the position;

[0040] Step 4: Pull out the pin shafts connecting the positioning flange and the fixed ear plates, rotate the steel pipe through the rolling device 400 to the required angle, and then drive the pin shafts back in for fixation. The rotation angle is determined by the bolt holes on the flange to ensure the rotation accuracy. Then repeat Steps 3 and 4 until all the ear plates on one steel pipe are welded.

[0041] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit them.
