Similarly, the two beams 44, 44 are also spanned between the receiving portion 42b of the other first beam holder 42 and the other hook portion 43c of the second beam holder 43.

[0057] (4) Attach the temporary stand 45 onto the four beams 44. Details are as follows. Connecting temporary stand 45 Place the combination of beam 51, reinforcing angle 52, sliding plate 53, and upper gripping member 55a on top of beam 44, two at a time. Pass sewn bolt 65 through bolt hole 54 of sliding plate 53 from above. The downward force of the beam 44 is also applied to the gripping member 55b, and the gripping member 55b is fixed with a nut as shown in FIG.

[0058]In the manner described above, the installation of the heavy object temporary storage device is completed. Next, the heavy object 3 is placed on the fourth equipment installation via the heavy object temporary storage device 101. [0059] (5) Hang the lifting tool on the hanging base provided on the ceiling of the hoistway or on the side wall near the ceiling. Manual or electric chain blocks, electric winches, manual lever blocks, etc. can be used as lifting tools. Heavy object 3 is lifted to a position higher than temporary stand 45 using a lifting tool. If the bulk of the heavy load 3 is smaller than the gap between the beams 44, it is lifted through the gap between the beams 44. If the bulk of the heavy object 3 is larger than the gap between the beams 44, the outside of the beams 44 is detoured and lifted.

[0060] As an example, if the heavy object is a winding machine, the winding machine is long in the direction along the drive shaft, so with the drive shaft of the winding machine aligned along the beam 44, 44 and lift it up. After passing through beam 44, the winder is turned 90 degrees and lowered onto sliding plate 53.

[0061] (6) The heavy object 3 is slid from the sliding plate 53 to the equipment installation stand 4. The sliding board 53 is installed at the same height as the equipment installation stand 4, or is installed at a slight incline so as to be lower toward the equipment installation stand 4 side. Therefore, the heavy object 3 can be easily installed on the equipment installation stand 5.

[0062] (7) After installing the heavy object 3 on the equipment installation stand 5, the heavy object temporary storage device 101 may be left in the installed state, or it may be placed in the same manner as in the first embodiment. You can also remove the sewing bolts and nuts from each part.

[0063] Another installation method for installing the heavy object 3 on the equipment installation stand 4 using the heavy object temporary placement device 101 will be described below. After performing (1) and (2) above, attach the temporary storage stand 45 to the bottom of the heavy object 3. The heavy object 3 and the temporary stand 45 are lifted together using a lifting tool and lowered onto the beam 44. The temporary stand 45 is fixed to the beam 44 using the gripping members 55a, 55b, sewing bolts 56, and nuts. The heavy object 3 is removed from the temporary storage stand 45 and slid to the equipment installation stand 4. After this, the heavy object temporary storage device 101 is handled in the same manner as in (7) above.

[0064] As described above, according to the first and second embodiments, both heavy object temporary storage devices 100 and 101 can be easily installed. Furthermore, once the heavy object 3 is placed on the machine bed 2, the heavy object temporary storage devices 100, 101 can be removed, so that sufficient space in the hoistway can be secured.

[0065] In each of the embodiments, round holes and bolt holes are provided in each component to allow sewing bolts and bolts to be attached. In contrast to fastening with bolts, for example, by changing the round hole or bolt hole of one component to a screw hole, it is possible to fasten the other component with bolts. Also, instead of machining a screw hole, a nut may be welded to a round hole or bolt hole. In the second embodiment, four beams 44 were used. As for the number of beams 44, a necessary and sufficient number may be used based on the relationship between the weight of the heavy object 3 and the strength of the beams 44. Therefore, the number of beams 44 is not limited to four. In addition, the heavy object temporary storage device and the heavy object installation method using the same according to the present invention are not limited to the above-mentioned embodiments, and can be implemented with various modifications without departing from the gist thereof. It is something. Therefore, not only when heavy objects 3 are to be installed at the top of the hoistway, but also when they must be installed halfway up the shaft, heavy object temporary storage devices 100 and 101 can be attached to match the machine bed 2. 3 can be installed.

Industrial applicability

The heavy object temporary storage device according to the present invention is suitable for lifting heavy objects in situations where sufficient hanging allowance cannot be secured, such as when lifting heavy objects such as unwinding machines near the ceiling of a hoistway. available for use.
