The utility model adopts the following technical scheme:
the utility model provides an auxiliary device is corrected to hoist gate leg, auxiliary device installs on two gate legs of girder lower part, its characterized in that: the auxiliary device comprises a box girder I and a box girder II, one end of the box girder I and one end of the box girder II are respectively connected to one door leg, the other end of the box girder I and one end of the box girder II are respectively connected to two flanges, the inner rings of the two flanges are connected through jackscrews, and the outer rings of the two flanges are connected through double-headed nuts.
The upper parts of the two door legs are respectively connected with one end of a guy rope, and the other end of each guy rope is connected with a ground anchor.
The bottom of one of the door legs is provided with an anchor rod which is fixed in the anchor pit.
The utility model has the advantages that:
(1) the accurate control of the verticality of the crane door leg in the correction operation process can be realized by adopting a set of simple cable wind rope, ground anchor fixing system and flange connecting device.
(2) The adoption of the guy rope and the ground anchor has the advantages of flexible operation, safety and reliability; the flange connecting device is adopted, and the double-end screw, the nut and the jackscrew are adjusted, so that force is applied through the flange, the box girder is stretched and transferred to the door leg, additional bending moment is generated on the crane door leg, and the door leg is repaired through the additional bending moment. The whole repairing process is stable and reliable in action, the adjustment can be carried out while repairing, and the perpendicularity of the crane door leg can be accurately controlled.
