Description will be made with reference to the drawings. The device according to the invention consists essentially of a rotatable frame 1 which is rectangular in its basic position. This frame 1 has four vertical guide rods 2. The frame 1 is attached to a suitable lifting device (e.g. power shovel or crane) by a chain or cable running through the eye 3. A vertical guide rod 2 is provided with a sliding block 4 connected to two guide profiles 5.

The vertical guide rod 2 is pivotally supported on the arm 6. The arm 6 is pivotable about a vertical central longitudinal axis 7. By pivoting the arm 6 towards the dotted line 8, the two guide profiles 5 can be displaced in opposite directions.

Furthermore, the guide profile 5 is connected to a wire rope 9 (FIG. 2) which is guided through a pulley 10 by a drive (not shown), whereby the guide profile 5 is in the direction of arrow 11. Moved up and down in the opposite direction. A fixed support 12 for each guide profile 5 and a movable support horizontally movable in the longitudinal direction by rollers 13 '.
13 are provided. These supports 12, 13 are fitted with a gripping device or an eccentric (Exzenter) for gripping a hollow concrete block 14 whose contours match each other.

In order to allow horizontal movement of the hollow concrete block 14, an additional leveling wire rope 15 which moves through a pulley 16 is provided. The pulley 16 is rotatably mounted on a vertical central shaft 7 and rotates in a pulley support 17. The wire rope 15 is operated by a driving device (not shown).

The functioning of the device according to the invention is as follows. The wire rope 9 moves the left guide profile 5 and the supports 12, 13 and the right guide profile 5 and the supports 12, 13 in FIG. However, since the guide profile 5 is also attached to the arm 6 connected to the two central axes 7 at the center of the axes, the central vertical axis is corrected by moving the two guide profiles 5 in opposite directions.

When the two guide profiles 5 are moved up and down in opposite directions, the pulley support 17 is rotatable, so that the pulley 16 is rotated as indicated by the dotted line 18 in FIG.

As shown in FIGS. 4-6, the hollow concrete block 14 is initially in the basic position on the pallet with the contours 19 facing each other (FIG. 4). The hollow concrete block 14 is then gripped by a gripping device or an eccentric, lifted and distributed in the height direction. Further, the hollow concrete blocks 14 can be dispersed horizontally as shown in FIG. By moving the two guide profiles 5 to the opposite side, the central longitudinal axis is corrected and the two inner hollow concrete blocks 14 '
A tightly held relationship between is guaranteed. The amount of movement is indicated by x and y ₁ .

The inner hollow concrete block 14 '
The remaining two hollow concrete blocks 14 diagonally opposite to each other are connected to the wire rope 15 circulated by the movable supports 13 on the two guide rails. Since the pulley 16 is configured to be rotatable on the pulley support 17,
It is possible to operate under the condition that the pulley 16 is moved in the longitudinal direction and the condition where the axis of the hollow concrete block 4 is corrected. Therefore, y ₂ to be moved (backward a state where the hollow concrete block 14 is moved in the vertical direction
Can be moved).

The above-mentioned state is shown in FIG. Square (x +
y ₁ ), and then the horizontal wire rope (y ₂ ) brings the hollow concrete block 14 to the final position, that is, the state where the hollow concrete block 14 has been transferred, and the hollow concrete block ends are contoured in the upper row. , The end contours of the two hollow concrete blocks are laid one on top of the other so that the hollow concrete blocks engage when they are lowered towards the lower row of hollow concrete blocks.

During the operation of all machines, horizontal and vertical, with or without the loading of hollow concrete blocks, a static equilibrium (total force balance) is always maintained.

[0024]

The device according to the present invention has the following effects. Four hollow concrete blocks placed on the pallet with their contours facing each other are simultaneously lifted, displaced in the height direction and vertically separated at the required intervals, and the hollow concrete blocks in the upper row are separated from each other. It can be lowered to its final state when it engages the contours of a hollow concrete block.

As described above, according to the device of the present invention,
You can grab all four hollow concrete blocks supplied on the bullet at the same time, move them in a vertical line at the required distance, and lower them to the required places so that the contours of the two hollow concrete blocks will mesh. .
