The upper end of the eccentric sleeve is coaxially fixed with an adjusting disc. A plurality of adjusting holes for connecting with the fixing plate are fixed on the adjusting disc. The guide wheels are all passed through by a pin shaft and are rotationally connected therewith. The upper end of the pin shaft passes through the eccentric sleeve and is fixed; a connecting frame for connecting to the traveling crane frame is fixed on the fixing plate.

[0005] Further, eccentric holes for passing the pin shaft are opened at the same positions on the adjusting disc and the eccentric sleeve.

[0006] Further, the adjusting holes are all arranged in an annular array on the fixing plate, and threaded holes for cooperating with the adjusting holes and fastened by bolts are arrayed at the upper end of the fixing plate.

[0007] Further, there are eight groups of the adjusting holes evenly distributed, and four groups of the threaded holes are arranged in a square array.

[0008] Further, the upper end of the pin shaft is provided with an external thread and is fixed on the adjusting disc by a bolt.

[0009] Further, the connecting frame is vertically arranged with the fixing plate, and a reinforcing rib plate is fixed between the two.
