Flange steel pipe structure support assembling device capable of being adjusted in multiple directions

The invention relates to the field of flange steel pipe structure supports, in particular to a flange steel pipe structure support assembling device capable of being adjusted in multiple directions. The technical problem is that the installation distances of flange steel pipe columns are different, and after installation of a single flange steel pipe column is completed, installation of subsequent flange steel pipe columns cannot be continued. According to the technical scheme, the flange steel pipe structure support assembling device capable of being adjusted in multiple directions comprises a mounting frame, a fixing column, a mounting disc, a positioning column and the like; a plurality of fixing columns are mounted on the mounting frame; each fixing column is rotationally connected with a mounting disc in a damping manner; and a plurality of positioning columns are connected to each mounting disc in a sliding manner. The connecting ropes are additionally arranged at the joints of the mounting disc and the
