[Description of Operation] Using a simple crane, a wheel set 8 having two wheels 3 is guided on the grooved rolling wheels 4 as shown in FIGS. 1 and 2, and the flange portions of the wheels 3 are respectively mounted. It is placed and positioned on the two grooved wheels 4. On the other hand, a semi-circular brake disk 37 is carried into the locating pin mechanism A with a simple crane so that the arc portion is directed downward, and two locating pins 20 are operated so that the tips of the locating pins 20 are at the uppermost stage of the brake disk 37. The support of the brake disk 37 is transferred from the crane to the locate pin mechanism A by being inserted into the left and right bolt insertion holes 37a. In this state, the operation of the cylinder 10 guides the platform 11, that is, the elevator table 13 equipped with the locate pin mechanism A, the impact wrench mechanism B, the bolt head holding mechanism C, and the bolt support mechanism D, directly below the wheels 3. As shown in FIG. 12 a, the derake disc 37 is guided below the disc mounting seat 36 provided on the wheel shaft 8. Then, the brake disc 37 is adapted to the lower portion of the disc mounting seat 36 by the procedure shown in FIGS. 12B, 12C, 12D, and a bolt insertion hole 36a provided around the disc mounting seat 36 and a bolt provided on the center flange of the brake disc 37. Fit the insertion hole 37a. If both bolt insertion holes 36a,
If 37a is not suitable, the grooved wheel 4 is finely rotated by driving the servo motor 6. Then, FIG.
By inserting the locating pin 20 into the bolt insertion hole 36a of the disc mounting seat 36 according to the procedures a, b, and c, and pressing the flange portion of the brake disc 37 against the disc mounting seat 36 at the tip of the guide pipe 19, the brake disc 37 is Fixed. 14a to 14e, a bolt 42 is inserted into the bolt insertion holes 36a, 37a, and a nut is temporarily attached to a bolt projecting to the opposite side of the disc mounting seat 36, and the nut is fastened by the impact wrench mechanism B. I do. This bolt fastening is shown in FIG.
The procedure is performed in the steps b and c. That is, as shown in FIG. 15A, since the locating pin 20 is inserted in the uppermost left and right bolt insertion holes 36a and 37a, the left and right bolt insertion holes 36 one step lower than the left and right bolt insertion holes 36a and 37a.
a and 37a are fastened by bolts. And FIG.
After the locating pin 20 is retracted as shown in FIG. 15B, the wheel shaft 8, specifically, the brake disc 37 and the disc mounting seat 36 are rotated 31 degrees counterclockwise in FIG. . By this rotation, bolts are fastened to the uppermost bolt insertion holes 36a, 37a on the left side of the drawing and the third bolt insertion holes 36a, 37a from the top on the right side of the drawing, and then the brake disk 37 and the disk are mounted by the same operation. The seat 36 is rotated clockwise by 62 degrees, and bolts are fastened to the bolt insertion holes 36a and 37a at the third level from the top on the left side of the sheet and the uppermost step on the right side of the sheet,
One brake disk 3 for the disk mounting seat 36
7 is completed. When the mounting of one brake disk 37 is completed, the arc portion of the brake disk 37 is positioned immediately above, and the brake disk 37 is fastened to the remaining disk mounting seat 36 in the same procedure as described above.
At this time, the gap adjusting plate 41 of the gap adjusting mechanism E shown in FIG.
By removing the gap adjusting plate 41 by the cylinder 40 after the fastening is completed, a predetermined (for example, 1 mm) gap is formed between the brake disks 37. With the above operation, the fastening of the brake disk 37 to the disk mounting seat 36 is completed. If there are two disc mounting seats 36 on the wheel set 8, the wheel set 8 is turned 180 ° and the brake disc 37 is bolted in the same procedure.
