The handle 23c is located directly above the handle 23c, or is retracted to the side from the handle 23c.Function Next, the work of removing the beam installed on the carrier will be explained.

First, the carrier 17 carrying a plurality of beams 21 is placed on the turntable 1 so that its socket 18 fits into the socket base 14. Next, depending on how many beams 21 the mounted carrier 17 has, the cams 8 to 11 corresponding to the number of beams 21 are selected and the selected switch 12 is activated. This causes motor 3
is activated, the turntable rotates, and the switch contacts the first recess of the selected cam, stopping the turntable in a predetermined position. On the other hand, the turning cylinder 50 of the screwdriver 42 is extended to move the turning frame 51 from the position C to the position D in FIG. As a result, the clamp 74 provided at the tip of the rotating frame 51 is attached to the beam holding device 2.
It comes directly above 3. The carrier 17 is then manually rotated until its engagement projection 20 abuts the positioning stop 19. At this rotational position, fixing screw 1
6 is manually tightened to secure the carrier 17 to the socket base 14. Next, press the beam removal button (not shown). The setting table 29 in the lying state as shown by the chain line in FIG.
By stretching 1, it stands up in the vertical state shown by the solid line. After this standing up, the trolley 2 had retreated to position A in Figure 1.
6 moves forward to the illustrated position D by the extension of the traveling cylinder 27. As a result of this forward movement, the fork 33 provided on the setting table 29 is fitted into the beam 21 at a position on the lower surface of the flange 21a thereof. Next, the clamp cylinder 38 of the clamp device 34 is contracted, and the clamp 39 is lowered to enter the recess 21d of the upper flange 21b of the beam 21, thereby clamping the beam 21. Next, the lifting cylinder 72 is lowered to lower the crank 74 to a position where it engages with the handle 23c of the beam holding device 23. Then, the geared motor 54 is started to rotate the crank 74, and the handle 23c is rotated so that the screw rod 23a rises. As a result, the beam presser 23b is retracted above the upper end of the beam 21. When retracted, torque is detected by the torque guard 60 and limit switch 61, and the geared motor 54 is stopped. After this stop, the lifting cylinder 72 is operated to raise the crank 74 so that it is removed from the handle 23c. Next, the raising/lowering cylinder 31 is contracted to lower the setting table 29 to the position shown in chain lines in FIG. As a result of this collapse, the beam 21 is clamped by the fork 33 and clamp 39 of the setting table 29, and is then lowered together with the setting table 29, and is removed from the carrier 17. After this removal,
The traveling cylinder 27 is extended and the truck 26 returns to the initial position A in FIG. The clamp cylinder 38 then extends and clamps the clamp 39 to the upper flange 21.
b from the recess 21d to release the clamp on the beam 21. Then, the beam 21 is removed from the set table 29 by a suitable means such as a forklift and replaced with a separately installed stepladder or the like. When this beam removal work is completed, the motor 3 is activated by an appropriate switch, and the rotating shaft 2 is rotated. When the rotating shaft 2 rotates by a predetermined amount, the rotation is stopped by the cam. That is, the carrier 17 rotates by the distance between the beams placed on the carrier, and the next beam to be removed is set at the removal position. Then, the beam removal operation described above is performed. Repeat this process to remove all the beams on the carrier.

Next, the case of attaching the beam to the carrier will be explained. First, set the empty carrier 17 on the turntable 1, and place the carrier 17 on the cams 8 to 1.
1 and switch 12 to rotate it to a predetermined position and stop it. On the other hand, the turning cylinder 50 of the screwdriver 42 is extended to turn the turning frame 51 to the position D in FIG. 7. This operation is similar to the removal operation described above. Then, as shown by the chain line in FIG.
1 is placed using a forklift or the like. Incidentally, at this time, the trolley 26 and the setting table 29 have retreated to the illustrated position A. With this placement, the switch 40
is activated, the clamp cylinder 38 of the clamp device 34 is contracted, and the clamp 39 is moved to the beam 21.
The beam 21 is inserted into the recess 21d of the upper flange 21b, and the beam 21 is held between the clamp 39 and the fork 33. When the forklift or the like retreats and a switch (not shown) is actuated by this retreat, the travel cylinder 27 is extended and the truck 26 moves leftward and stops at a predetermined position (b). Next, the raising/lowering cylinder 31 is extended to vertically raise the setting table 29 holding the beam 21. As a result, the lower end of the beam 21 fits into the beam fitting part 22 on the carrier and stands up on the carrier. Then, the clamp 74 is brought into engagement with the handle 23c of the beam holding device 23 by the lowering operation of the lifting cylinder 72. Then, the geared motor 54 is rotated in the opposite direction to that during the removal operation, and the rotation of the clamp 74 causes the handle 23c to be rotated in the tightening direction. Thereby, the beam presser 23b presses and holds the upper end of the beam 21. Upon completion of this tightening, the torque guard 60 and limit switch 61 detect the torque and stop the geared motor 54. After this stop, the lifting cylinder 72 operates upward to retract the crank 74 above the handle 23c.
Next, the clamp cylinder 38 moves upward to remove the clamp 39 from the upper flange 21b of the beam 21. Then, the traveling cylinder 27 is compressed to horizontally move the set table 29 together with the truck 26 to the right and retreat to the position A in the figure. Next, the raising/lowering cylinder 31 is contracted to raise and lower the setting table 29 to a horizontal state. After this work is completed, the turntable rotates the carrier by the distance between the beams placed on the carrier, as described above. Then, repeat this process to attach all the beams to the carrier.

G. Effects of the Invention As described above, according to the present invention, the work of attaching and detaching the beam to the beam carrier can be performed mechanically and can be automated, which can relieve the worker from heavy labor and save labor. There are features that can contribute.
