The construction material 1 hoisted by the rope 2 from the hoisting device L is a gate-type hoisting with the lower joint bar 3, the lock plate 4, and the lower end surface opened as shown by the dotted line in the lower part of FIG. It is joined to the rope 2 by a frame 5. The rope 2 of the suspension frame 5 changes its direction by a constant pulley 6 and is hoisted by the lifting device L having a high lift composed of a motor 7, a reduction gear 8 and a winch drum 9 (see FIGS. 2 and 4).

Immediately below the lifting device L, the suspension frame 5 is provided.
The hanging frame 5 is required so that the hanging frame 5 can be accurately stopped at a predetermined position. Reference numeral 11 is a steady rest. The suspension frame 5 wound up by the lifting device L ascends while smoothly sliding on the receiving frame 10 whose lower end spreads like a trumpet, and the stopper 1
Stop at 2 and 13. As a result, the lower joint bar 3 can be accurately held in the vertical and horizontal positions and stopped. In the figure, 14 is a stud.

Next, referring to FIGS. 2 and 4, the working device 1 in the patent application proposed by the present inventors, Japanese Patent Application No. 4-156713, "Method of combining, storing, and exchanging construction work machinery".
5 is suspended from the temporary stage S via a beam 16, a traveling rail 17, a work machine W, and a telescopic beam 18 so that it can be moved to a required place in a plane. As described above, it is suspended from the upper part of the lock plate 4 of the lower joint bar 3 joined to the lower end of the suspension frame 5 stopped accurately at a predetermined position from the work device 15 of the work machine W via the rope 19. The upper joint bar 20 is hung down by the operation of the working device 15, and the upper joint bar 20 is slid between the lock plates 4 which are widened in a trumpet shape to the upper part to bring the upper joint bar 20 into overall contact with the lower joint bar 3. Upper and lower splicing bars 3,
After confirming that 20 is surely contacted, by fitting and operating the bolt attaching / detaching device A fixed to the stud 14 of the temporary stage S to the lock bolt device F fixed to the lock plate 4 in FIG. Lock plate 4 and upper joint bar 20
Are joined.

The bolt attaching / detaching device A has a friction piece 23 slidably fitted so as to be pushed forward by a spring 22 held by a screw plug 21 and a ball bearing 24 for releasing a rotational frictional force at the time of pressing. , Further pin screws 2 to prevent falling
A hexagonal screwdriver 26 that is rotatably locked at 5 and a holder 27 that integrates the hexagonal screwdriver 26 and a holder 27 that integrates them together are slidable in the axial direction of the lock bolt 28 via a slide tool 29. The motor M attached to the stud 14 is joined to the lock bolt 28 of the lock bolt device F by coupling with a coupling 30 and sliding a distance in the direction of arrow a in FIG.

On the other hand, in the lock bolt device F, the head portion of the lock bolt 28 is rotatably screwed into a bolt holding cylinder 31 fixed to one side of the lock plate 4 so that the lock bolt 28 can be rotated.
Is provided with a hexagonal hole into which the hexagonal driver 26 can fit without a gap, and the lock bolt 28 is propelled forward by being rotated by the rotational force of the motor M through the hexagonal driver 26. Mounting hole 2 for upper splicing bar 20

Contact and screw to 2. At the same time as the arrow of each part in FIG. 3 propels the distance b, the head of the lock bolt 28 reaches the bottom of the bolt holder and becomes unrotatable, so that the friction piece 23 in the holder 27 and the hexagonal screwdriver 26 are Slip occurs on the mutual friction surfaces, and the overtightening of the lock bolt 28 can be prevented. This is detected by a detector (not shown), and the bolt attaching / detaching device is retracted to complete the lock on the lock plate 4.

Then, similarly to the lock plate 4, in the lock plate 4a having the lock bolt device F and the bolt attaching / detaching device A, the lock bolt 28 is already screwed into the nut 32, so that the lock bolt 28 in the lock plate 4 is screwed. The bolt attaching / detaching device A is operated so that the procedure, the rotating direction, and the moving direction are completely opposite to the tightening described in (1), and the lock of the lock plate 4a is released. At this time, the working device 15 is actuated to slightly pull up the lower joint bar 3 to release the load of the mounting hole 20a of the suspension frame 5 from the lock bolt 28 of the lock plate 4a,
Convenient to rotate and pull out.

After the lock plate 4a is unlocked,
By the operation of the work device 15, the rope 19 is unrolled, the construction material 1 is lowered through the vertical joining bars 3 and 20, and it is confirmed that the lock plate 4a is isolated under the suspension frame 5, and the work machine W or the telescopic beam. 18 is moved to start the horizontal conveyance of the construction material 1 which has been completely transferred. Due to the above, a working machine W that requires a smaller lifting height than a lifting device L that has a large lifting height
