DESCRIPTION OF EMBODIMENTS Hereinafter, embodiments for carrying out the present invention will be described in detail with reference to the drawings.
(Overview)
At the time of dismantling a high-rise building, the potential energy of the suspension device used when lowering a heavy dismantled object from the construction floor to the ground is used for the lifting force of another lifting device.
In this case, the relationship of the weight of the hanging device plus the amount of hanging load> the weight of the lifting device is established.
Moreover, the suspension device can be raised by setting the weight of the suspension device <the weight of the lifting device.
The suspension device and the lifting device perform counterweight functions with each other via these connecting wires. For example, compared to a case where separate lifting equipment is used, the load of the emergency stop mechanism and speed control mechanism necessary for the wire is required. Can be reduced.
Also, by embedding two types of springs on the bottom surface below the lifting device and providing a level difference, it is possible to use a normal shock buffering spring and a life protecting spring when falling.

(Embodiment)
FIG. 1 shows a configuration of an embodiment of a dismantling operation of a high-rise building to which the present invention is applied. 1 is a high-rise building, 2 is a steel frame, 3 is a soundproof wall, 4 is a hanging device, 5 is a lifting device, 6 is a wire, 7 is a guide rail, 8 is a pulley, 11 is a speed control device, and 12 is an emergency stop device.

The illustrated example shows the dismantling of the S, RC, or SRC high-rise building 1 during the dismantling work at the uppermost layer. As shown, the steel frame is located above the dismantling work floor (construction floor). 2 is assembled and installed, and a soundproof wall 3 covering the periphery of the construction floor is attached.
The steel frame 2 is loaded with heavy objects (dismantled materials) such as a housing crushed into small parts on the construction floor and suspended from the suspension device 4 for suspending it on the ground, and the person or material is moved up and down to the work floor. The ceiling of the elevating device 5 to be lifted is supported by being suspended via the same wire 6.

That is, on the floor from the construction floor to the second floor, an opening 1a through which the suspension device 4 is passed is formed at the same place on the plane, and an opening 1b through which the lifting device 5 is passed is formed.
A guide rail 7 is fixed to the housing in the vertical direction through the opening 1b through which the lifting device 5 passes, and is installed on the pillar by anchoring or PC tightening, for example, and the lifting device along the guide rail 7 Five cages are assembled so as to be movable up and down.
The guide rail 7 is configured so that it can be divided in units of floors.

Further, the steel frame 2 is provided with a pair of pulleys 8 positioned immediately above the openings 1a and 1b, and wires 6 are hung on the pair of pulleys 8, respectively.
Further, the steel frame 2 is provided with a speed control device 11 using a gear mechanism and a speed reduction mechanism for controlling the moving speed of the wire 6 between the pair of pulleys 8, and the movement of the wire 6 is urgently stopped manually or the like. An emergency stop device 12 is provided.

Here, the steel frame 2 in the upper part of the construction floor has sufficient strength to support the weight A of the suspension device 4 and the weight B of the lifting device 5 sufficiently.
If necessary, existing slabs and beams will be reinforced.

  As described above, the suspending device 4 is provided with a weight measuring means (not shown) and a stopper mechanism for restricting the wire 6 from moving until a load having a predetermined weight is loaded.

  In addition, an emergency stop button 5a is provided in the cage of the lifting device 5 as shown in the figure.

  The emergency stop device 12 operates based on the monitoring of the moving speed of the wire 6 by the speed control device 11, and also operates by manual operation of the emergency stop button 5a.

  And the sum total of the weight of the hanging apparatus 4 and the load (dismantled article) to be hung on it is set to a value equal to or greater than the weight B of the lifting apparatus 5 and its load capacity.

  As described above, as shown by the arrows in the figure, the crushed glass that is a dismantled product is placed on the suspension device 4 and suspended, thereby raising the worker who has entered the lifting device 5 via the wire 6.

  Next, the basic principle of the embodiment will be described.

<Basic principle>
First, by setting the hanging device weight A to the lifting device weight B, the functions of the counterweights are obtained.
Then, when it is desired to lower the suspending device 4 and raise the lifting device 5, the driving force can be obtained by setting A> B.
Conversely, when it is desired to raise the suspending device 4 and lower the lifting device 5, the driving force can be obtained by setting A <B.

  FIG. 2 is an enlarged view of an example of the internal structure of the first floor below the lifting device 5, wherein 13 is a pit, 14 is a buffering spring, 15 is a hook receiving member, and 16 is a powerful spring for protecting human life.

As shown in the drawing, a pit 13 is formed on the first floor below the lifting device 5, a pair of buffer springs 14 are installed in the pit 13, and a hook is received at the upper ends of the pair of buffer springs 14. The member 15 is fixed.
Furthermore, a life-saving strong spring 16 is installed between the pair of buffer springs 14 in case of a crash. The life protecting strong spring 16 is installed at a position lower than the buffering spring 14 so as not to act at all times.

  In the equipment in the pit 13 described above, only the buffering spring 14 always operates. However, when the assumed lowering speed is exceeded, the buffering spring 14 exceeds the limit displacement and the life protecting strong spring 16 operates. Then, the impact of the eaves of the elevating device 5 is reduced.

  Next, the operation of the embodiment will be described.

(Function)
In the suspending device 4, the weight is measured by the weight measuring means, and the wire 6 is restricted from moving by the stopper mechanism until a load having a predetermined weight is loaded.
The elevating device 5 does not require a power source such as electric power or hydraulic pressure, and reaches the construction floor (top floor).

The wire 6 can be urgently stopped by the emergency stop device 12 when the user of the lifting device 5 manually operates the emergency stop button 5a.
Since the guide rail 7 can be divided on each floor, the rail can be removed one layer at a time as the disassembly progresses.

In the pit 13, the panel of the buffer spring 14 is soft and has a shock absorber function when stopped at a low speed.
Further, the life-saving strong spring 16 acts before the buffer spring 14 is shrunk when it is dropped at high speed, and prevents the lifting device 5 from directly colliding with the ground due to the strong spring.

  In addition, as the construction floor is lowered, the wire 6 is wound by a winding device (not shown) by a predetermined length, the wire 6 itself is replaced, or the wires 6 divided in advance by a predetermined length are connected. It is possible to deal with it by removing it by a predetermined length.

  Next, effects of the embodiment will be described.

(effect)
As described above, it is possible to provide the lifting device 5 that lifts and lowers a person or material when the elevator cannot be used in the dismantling of the high-rise building 1.
Moreover, in the dismantling work, it is necessary to hang a large amount of heavy objects (dismantling material) from the construction floor to the ground, and the lifting device 5 that uses the potential energy. Therefore, the power source required for general elevators and lifts The power source and the power source such as a power device or a hydraulic device are not necessary, and there is an energy saving effect.

Then, the weight A of the load suspended by the suspension device 4 and the dismantled material is set to a specific range that is equal to or greater than the weight B of the lifting device 5 and its allowable load, so that the speed control device 11 is hardly burdened. It is possible to move up and down.
On the other hand, when there is no load (disassembled material) in the suspension device 4, it is possible to return the suspension device 4 to the construction floor by making the suspension device weight A lighter than the lifting device weight B.

  Moreover, since the manual emergency stop device 12 is provided, the suspension device 4 and the lifting device 5 can safely reach any floor.

  Further, by providing a difference in the level of contact between the buffer spring 14 installed in the pit 13 and the strong life-protecting spring 16, it is possible to ensure a comfortable stop at all times and safety in an emergency.

As described above, according to the suspension device 4 and the lifting device 5 that constitute the dismantled object transportation facility for a high-rise building according to the embodiment, the dismantled object is placed on the suspension device 4 from the dismantling construction floor of the high-rise building 1 and lowered to the ground. By utilizing the potential energy for the lifting force of the lifting device 5, the dismantling from the construction floor can be suspended and the worker can be raised to the construction floor at the same time. Is also possible.
Therefore, the power unit is unnecessary and the cost can be reduced.

(Modification)
Needless to say, in addition to the above-described embodiments, specific detailed structures and the like can be changed as appropriate.
