Abstract

The invention discloses a height regulation tool and height regulation method used for sky train rail box girder elevation regulation. The technical problem that due to the fact that a traditional elevation regulation tool in the prior art is not ideal in regulation precision, the high-precision requirement during sky train rail box girder installation cannot be met is solved. The height regulation tool comprises a tool body, a guiding and positioning mechanism, a fixing mechanism and an elevation regulation lead screw. The elevation regulation lead screw is detachably connected with the fixing mechanism and the guiding and positioning mechanism in a screw thread manner. The height regulation method mainly includes the steps that spot welding fixation is conducted on the height regulationtool; and a fixing nut and a guiding and positioning nut are unscrewed, the elevation regulation lead screw is rotated so that the height of the elevation regulation lead screw can be precisely regulated to the required elevation position, and the guiding and positioning nut and the fixing nut are sequentially screwed so that the elevation regulation lead screw can be vertically fixed. The heightregulation tool and the height regulation method are simple in structure, scientific and reasonable in design and convenient to use, and the elevation required by the tool can be accurately obtained through regulation so that the high-precision requirement during sky train rail box girder installation can be met.

Description

technical field [0001] The invention belongs to the technical field of installation elevation adjustment of box girders on empty railway tracks, and in particular relates to a height adjustment tool and a height adjustment method for adjusting the elevation of box girders on empty railway tracks. Background technique [0002] In the production process of the empty railway track beam, the elevation of different parts of the box girder is different when it is assembled and welded. Therefore, in the actual production process, it is necessary to frequently build elevation adjustment fixtures at different elevations. The traditional elevation adjustment fixtures built have unsatisfactory adjustment accuracy and cannot meet the increasingly higher precision requirements for the installation of empty railway track box girders. At the same time , The traditional level adjustment tooling is poor in general purpose, and it is generally difficult to recycle and reuse, resulting in wast...
