クを吊上げて据え付けるものである。Next, the procedure for controlling the posture of the four-legged block 20 using the posture control device 10 according to the present invention will be described. This posture control device 10 is, for example, as shown in FIG. It is installed between a large number of four-legged blocks that are statically placed at A and the installation crane 36, and the installation crane 3
After mounting this four-legged block on the tray 26 of the attitude control device 10 using 6, the operator of the installation crane 36 operates the remote control device 34 to perform desired attitude control,
Again, this four-legged block whose posture is controlled by the installation crane 36 is hoisted and installed.

傾斜できるように設定しておけば良いことがわかる。The operation of the attitude control device 10 itself will be described in more detail. The four-legged block 20 whose attitude is controlled by the attitude control device 10 is tilted as shown in FIG. 5 because of its geometrical characteristics. As it goes, any one of the upright posture A, the inverted posture B, and the dragonfly posture C is obtained, and the other postures are the postures inclined in any direction. Therefore, it is sufficient to tilt the erecting posture A from the inverted posture B by about 63 degrees, and from the upright posture A to the dragonfly posture C by about 55 degrees, so that the suspension frame member 16 can be inclined up to about 63 degrees. You can see that you should set it.

Determine which posture of C is the basic posture. Then, first, the four-legged block 20 is placed on the pan 26 in an upright posture. Next, if the inverted posture B is the basic, the leg 26a located at the bottom in the inverted posture B by rotating the tray 26 by the operation of the rotary drive device 22 by the remote control device 34.
And the horizontal axis 14 of the suspension frame member 16 are aligned and aligned so that they are orthogonal to each other, and the suspension frame member 16 is further rotated by the rotation drive device 18 at a desired angle (in the case of the inverted posture B itself, 62.45). By tilting and holding only
It suffices to wait for the hoisting installation work by the installation crane 36. In this case, the leg portions 20a come into contact with the rising portions 26a of the tray 26, and the leg portions 20a are connected to the hook members 32.
It is fixed to the pan 26 by means of (see FIG. 6a).

照)。On the other hand, if the dragonfly posture C is basic, the direction of the axis of a predetermined leg of the four-legged block 20 placed on the tray 26 in the upright posture is set to the remote control device 34 as described above.
The saucer 26 is rotated by the operation of the rotary drive device 22 to set a predetermined direction and each leg is fixed to the saucer 26 by the hook members 32. Next, the rotary drive device 18 is used to move the suspension frame member 16 to a desired angle (54.35 degrees in the case of the dragonfly inverted posture C itself).
Only by holding it at a slant, it is sufficient to wait for the lifting and installation work by the installation crane 36 (see FIG. 6b).

ることができる等種々の利点を有する。As described above, according to the attitude control device of the present invention, the four-legged block can be easily set to a desired installation attitude by combining the operation of rotating the tray and the operation of inclining the suspension frame member. Since it can be controlled and held, the installation work of this type of four-legged block can be mechanized, and therefore, not only the installation work efficiency but also the safety improvement can be achieved. Further, since the counterweight is arranged at a position facing the horizontal axis of the suspension frame member, the rotational moment generated when the four-legged block is tilted is reduced, and the tilting operation can be performed extremely easily. Since the posture control is performed by remote control, there are various advantages such as improvement of safety during movement or installation work.
