DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION The present invention relates to a method for removing a heavy object such as a mold from an object.
The present invention relates to a heavy object reversing device for reversing 0 °.

[0002]

2. Description of the Related Art FIG.
As shown in FIG.
A drum driving unit for driving the drum 600 to rotate; and a support base 61 for rotatably supporting the drum 600.
0. The reversing of the heavy object by the heavy object reversing device is performed by rotating the drum 600 by 180 ° in the direction of the arrow from the state shown in FIG. In the drawing, reference numeral 620 denotes a spacer whose thickness changes depending on the size of the heavy object 400.

[0003]

However, the above-mentioned conventional heavy goods reversing device has the following problems. That is, in addition to the installation space for the heavy goods reversing device,
This requires space for the heavy article 400 to enter and exit the drum 600. On the other hand, if a normal heavy goods rollover device is used, no space is required for the heavy goods 400 to enter and leave the drum 600. However, as shown in FIG. (See FIGS. 9A to 9C), the heavy object 400 is lifted, and
It must be rotated 80 ° horizontally (see FIG. 9 (D)), and then the weight 400 must be rolled over 90 ° again. For this reason, although there is no need for a space for moving heavy objects into and out of the drum 600, multiple steps such as hanging heavy objects with a crane are required. For this reason, the surface of the heavy object may be damaged.

SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances, and does not require a space for loading and unloading a heavy object, and can perform continuous inversion without fear of damaging the surface of the heavy object. It is an object of the present invention to provide a heavy-weight reversing device capable of shortening the time required for the reversal.

[0005]

And a reversing table provided on one of the heavy load supporting surfaces, the first reversing table supporting a bottom surface of the heavy object, a second reversing table supporting a side surface of the heavy object, and a first and a second reversing table. A reversing table driving unit for driving the second reversing table; moving the heavy object supported by the first reversing table and the second reversing table by the reversing table driving unit; The drum is brought into contact with the heavy load supporting surface, and the drum is moved with the first and second reversing tables and the other heavy load supporting surface supporting the heavy load.
It is designed to rotate by 0 °.

The operation of the thus configured heavy goods reversing device will be described. First, use the crane 500 to
00 is placed on the first reversing table 310. At this time, FIG.
As shown in (2), the heavy object 400 is not placed on the second reversing table 320, and the corners of the heavy object 400 are positioned at the connecting portion 340. In the following description, the first reversing table 3
The surface in contact with 10 is the bottom surface 410 of the heavy object 400.

Next, as shown in FIG. 2, the second hydraulic cylinder 332 is driven to move the second reversing table 320 to the heavy object 40.
0 side 420. At this time, the second hydraulic cylinder 332 is in the most extended state.

In this state, namely, the bottom surface 4 of the heavy object 400
10 is the first reversing table 310, and the side face 420 is the second reversing table 3
The first hydraulic cylinder 331 and the second hydraulic cylinder 332 are driven in a state where the first hydraulic cylinder 331 and the second hydraulic cylinder 332 are supported. That is, the first
At the same time as the hydraulic cylinder 331 is extended, the second hydraulic cylinder 332 is contracted in conjunction with the extension, and as shown in FIG.
It is moved to the 10B side.

Then, as shown in FIG.
The upper surface 430 of the heavy object 400 is the other heavy object supporting surface 110B, the bottom surface 410 of the heavy object 400 is the first reversing table 310,
The 0 side surface 420 is supported by the second reversing table 320 from three directions. Thus, the weight 400 has been rolled over by 90 °. In this state, the first hydraulic cylinder 331 is in the most extended state, and the second hydraulic cylinder 332 is in the most contracted state.

Next, in this state, the drum 100 is rotated as shown in FIG. That is, the weight supporting surface 11
0A stands upright, and the weight support surface 110B is made horizontal. The rotation of the drum 100 is guided by a support roller 220. The rotation of the drum 100 is continued, and the heavy load supporting surface 110A stands upright,
When 10B becomes horizontal, the rotation of the drum 100 is stopped. As a result, as shown in FIG.
In the case of 0, since the bottom surface 410 is on the top, it means that the 180 ° inversion has been completed.

As shown in FIG. 7, the first hydraulic cylinder 33
1 to drive the first reversing table 310 upright. As a result, the bottom surface 410 of the heavy object 400 that has been raised is opened. The heavy object 400 is lifted by the crane 500. 180 of the weight 400 by the procedure as described above.
° Inversion is completed.

The drum is rotated by 90 ° with the heavy object supporting surface supporting the heavy object.

Therefore, like the conventional heavy object reversing device,
It does not require space for loading and unloading heavy objects, and can be installed in narrow places. Further, unlike the case of using the conventional heavy object rollover device, there is no need to suspend the heavy object, and the inversion can be automatically and continuously performed, so that there is no risk of damaging the surface of the heavy object, and it is necessary for the inversion. Time can be reduced.
