DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for transporting heavy objects in a high-rise building.

[0002]

2. Description of the Related Art Conventionally, when a heavy object is lifted in a high-rise building, for example, when a heavy object such as a rotor installed in an elevator machine room is replaced, a part of the high-rise building is broken. After securing a passage through which objects can be carried into the machine room, heavy objects placed on the ground are lifted with a crane or the like and lowered into the above-mentioned new passage, and the dropped heavy objects are carried into the machine room using a winch or the like. Or a staircase in a high-rise building as a carry-in route, and a stair-lifting device that lifts heavy goods is placed on the stairs, and heavy objects placed on the ground can be moved from the first-floor stairs to the destination floor. After being moved using a stair lifting device, it was carried into the machine room from the destination floor using a winch or the like.

[0003]

However, the above-mentioned conventional method of transporting heavy objects requires the use of a large crane for lifting heavy objects and the breaking of a part of a high-rise building in the former case. Because of this, the construction period from rehabilitation increases, and in the latter case, it is necessary to re-install stair lifting equipment for each floor, and it is necessary to move heavy objects slowly and slowly. This will inconvenience people who use high-rise buildings for a long time. On the other hand, it is conceivable to transport a heavy object to a higher floor using an elevator. However, the elevator has a rated loading weight and cannot transport a heavier object than this. It is conceivable to transport a heavy object by dividing it below the rated load weight of the elevator, but it takes time for subsequent reassembly and cannot be said to be an efficient transportation method.

[0004] It is an object of the present invention to provide a method of transporting a heavy object that can be carried to the top floor of a high-rise building using an elevator even if the object is heavier than the rated load weight of the elevator.

And characterized in that:

According to the above-described method for transporting heavy objects according to the present invention, since predetermined parts other than the frame of the existing elevator are removed, the actual car weight is reduced, and the heavy object is mounted on this frame. In addition to the rated load of the elevator, the weight of the removed parts plus the weight of the specified parts can be transported by the elevator, requiring the breaking of some high-rise buildings and the need for large hoists as before. Without using a dedicated stair lifting device, it is possible to use an elevator to transport a heavy object that is heavier than the rated load weight of the elevator in a relatively short time.

[0007]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a side view showing a schematic structure of an elevator employing a method for transporting heavy objects according to an embodiment of the present invention. A hoisting machine 2 is disposed in a machine room 1 of an elevator. Both ends of a rope 6 wound around a sheave 2S of the hoisting machine 2 are respectively suspended in a hoistway 3 and connected to a car 4 and a counterweight 5. Have been. The basket 4 includes a frame 11
, A door 12 and a side plate 13 are attached. As will be described in detail later, a buffer 7 is provided in the pit 14 of the hoistway 3, and the base 10 of the buffer 7 and the frame 11 of the car 4 are connected by a chain block 8 as a holding means. 2 to 8 are cross-sectional views showing a method of transporting a heavy object using the above-described rope-type elevator along with the operation procedure. In the elevator, the rated load of the car 4 is determined depending on the model, and it is not possible to carry any more load. Therefore, it is not possible to transport a heavy object having a load greater than the rated load by the elevator in connection with the repair work of the elevator. Therefore, as shown in FIG. 2, first, a weight 21 having a predetermined weight is mounted in the car 4,
For example, it is transported to the top floor 10F, and the weight 21 is put down at the platform on the top floor 10F. Thereafter, the car 4 is lowered to a predetermined floor, for example, the lowest floor 1F, and the frame 11 of the car 4 and the base 10 of the shock absorber 7 are connected by the chain block 8 as the holding means described with reference to FIG.

Thereafter, as in the disassembly step shown in FIG. 3, the car 4 is disassembled while leaving at least the frame 11, and the door 12 and the side plates 13 are removed. With the progress of this work, the balance with the counterweight 5 is lost, and the sheave 2S of the hoisting machine 2 is lost.
Slip occurs between the car and the rope 6, but the frame 1 of the car 4
1 and the base 10 of the shock absorber 7 are connected by a chain block 8 which is a holding means, so that the car 4 and the counterweight 5 maintain the illustrated state. At the time when the disassembly of the predetermined parts is completed, the car 4 having only the frame 11 reduces the actual car weight, and places a heavy load on the frame 11 by adding the rated load to the reduced part weight. It can be mounted. For example, the weight of the cage 4 is 2000 kg, and the frame 11
Is 1000 kg, and the rated load is 900 kg, the weight of the disassembled part is 1000 kg, and the loadable weight of the car 4 having only the frame 11 is 200 kg.
0Kg-1000Kg + 900Kg = 1900Kg, 1900 for elevators with a rated load of 900Kg
It is possible to carry heavy objects up to Kg.

Next, as a carrying-in step shown in FIG. 4, the heavy goods 20 carried to the first floor are carried into the frame 11, and the frame 11 of the car 4 and the base 10 of the shock absorber 7 are connected. Remove the chain block 8. Next, in the transportation step shown in FIG. 5, the frame 11 on which the heavy object 20 is loaded is moved to another predetermined floor, for example, the top floor 10F by operating the hoisting machine 2. After that, the lower part of the counterweight 5 is held using the rod 15 which is a holding body carried into the pit 14 of the hoistway 1,
Prevents downward movement. It is desirable that the rod body 15 has a square member such as a cylindrical steel pipe, a shape steel or a hardwood, and a jack-up base for height adjustment.
The counterweight 5 is held at a predetermined position so that the car 4 does not move when the heavy object 20 is lowered.

Next, in the carrying-in / out step shown in FIG. 6, the heavy object 20 is carried out of the frame 11 to the landing on the top floor 10F, and the load 21 described with reference to FIG. As can be seen from this description, the load body 21 previously carried into the top floor 10F has a weight corresponding to the parts disassembled from the car 4 and if the load exceeds the maximum load capacity of the elevator, the load body 21 must be loaded several times. Transport separately. When an existing heavy object corresponding to the heavy object 20 is taken out in place of the heavy object 20, the existing heavy object is mounted on the frame 11 from the top floor 10F, so that the preparation of the load body 21 is unnecessary, and When there is a weight difference between the heavy object 20 to be carried in and the existing heavy object to be carried out, a load body 21 corresponding to the difference may be prepared.

Next, in the frame moving step shown in FIG.
Is removed, and the hoisting machine 2 is operated to lower the frame 11 to the lowest floor 1F of the predetermined floor. When the frame 11 is stopped, the frame 11 is again moved to the base 10 of the shock absorber 7 by the chain block 8. Fixed to. In this state, the load 21 is carried out to the lowest floor 1F. Accordingly, the balance between the counterweight 5 and the frame 11 is lost with the progress of this process, and a slip occurs between the sheave 2S of the hoisting machine 2 and the rope 6, but the base of the frame 11 and the base of the shock absorber 7 are formed. Since the spaces 10 are connected by the chain block 8 as a holding means, the frame 11 and the counterweight 5 maintain the illustrated state. Thereafter, a car restoration process shown in FIG. 8 is performed. After the doors 12 and the side plates 13 and the like removed for the present transportation are attached to the frame 11 again, the car restoring operation is completed when the chain block 8 is removed.

Thus, at least the frame 11 of the car 4
By disassembling the other parts except for, the heavy object 20 which is heavier than the rated load of the elevator can be carried by the elevator, and can be carried to the predetermined floor of the high-rise building in a short time. Therefore, since it is not necessary to break a part of the high-rise building as in the related art, the cost can be reduced without lengthening the construction period including the repair.

In the above-described embodiment, all parts other than the frame 11 of the car 4 are removed. However, in consideration of the weight of the heavy object 20 to be conveyed, the weight exceeding the rated load of the elevator is considered. Alternatively, only the parts corresponding to may be removed. In addition, the existing heavy goods 20 are transferred to the top floor 10F.
When transporting from the first floor to the lowermost floor 1F, the respective steps are performed in reverse from the state of FIG. 8 to the state of FIG. In any case, if the car 4 is partially dismantled on the lower floor such as the lowest floor 1F, the work can be performed safely.

[0014]

The method for carrying heavy objects according to the present invention is as described above.
, The effects listed below can be obtained.
Can be. a. Even if a heavy object is heavier than the rated loading capacity of the elevator, the heavy object is divided without being divided from the bottom floor of the high-rise building to the top floor without using a large crane or stair lifting equipment. It becomes possible to carry safely by using. b. In order to transport a heavy object that is heavier than the rated load capacity of the elevator from the bottom floor of the high-rise building to the top floor, it is not necessary to break or repair a part of the high-rise building. c. Even if the load is heavier than the rated loading weight of the elevator, the load does not need to be disassembled and transported, and the work of disassembling and assembling the load becomes unnecessary. d. Since the operations described in “b” and “c” are not required, the operation time for transporting heavy objects can be significantly reduced.
