Description

[Technical field]

[0001] The present invention relates to a method for transporting heavy objects such as outdoor units for air conditioners and cubicles serving as high-voltage power receiving equipment to the rooftops of buildings to their installation locations or transporting them to collection locations. [Background technology]

[0002] Conventionally, for heavy objects, such as outdoor units for air conditioners to be installed on the rooftops of buildings, a normal crane has been placed in the open space around the building and used to transport the objects in and out. When constructing a new building, a tower crane or a temporary construction lift has been set up to carry out the lifting work.

[0003] In some cases, there is no space for a normal crane, so crane work is not possible at all. In some cases, a permanent elevator must be used to bring in outdoor units and other items to the rooftop of an existing building. In such cases, a permanent elevator cannot transport cargo, especially heavy items such as outdoor units, so in the past, the items had to be disassembled and lifted to the top floor, which took a long time as manual labor, and when there were a large number of units, it was quite a complicated and difficult task. When removing and transporting outdoor units from the rooftop for repair or replacement, the exact opposite work had to be done, which was equally difficult.

[0004] Therefore, in order to avoid the above-mentioned situation, a separately installed lifting device is used. Various types of lifting devices have been proposed, such as a device consisting of an extension ladder installed along the wall of a building (Patent Document 1) or a prefabricated simple rooftop crane that allows for more stable and safe lifting (Patent Documents 2 and 3). [Prior art documents] [Patent documents]

[0005] [Patent Document 1] JP 2003-118999 A [Patent Document 2] Patent No. 5881381 [Patent Document 3] Patent No. 6203104 Summary of the Invention [Problem to be solved by the invention]

[0006] In order to carry in or out heavy objects such as outdoor units using the lifting devices disclosed in the above Patent Documents 1 to 3, a specially constructed telescopic ladder member and other members such as auxiliary supports that further support the ladder member, as well as multiple movable pulleys and fixed pulleys, are required. Even a simple, prefabricated crane requires components for a dedicated machine. Therefore, if the building is relatively tall or if the building is located in an unusual place or has an unusual shape, the number of components that make up a custom-made lifting device will increase, and manufacturing costs will be considerable, resulting in high costs for the entire loading and unloading operation.

[0007] In addition, installing these lifting devices on the rooftops or around buildings requires a certain amount of space, although it is not as much as installing a normal crane. In areas where buildings are built up or where the building itself has an unusual shape, there are many sites where it is not possible to secure adequate space, making it impossible to install and use the lifting device itself.

[0008] In addition, when an outdoor unit, etc. is installed on the roof of a building and then removed for repair or replacement after a certain period of time, the tower cranes and construction lifts installed during the construction of the new building have already been dismantled, and new buildings have been constructed around the building, and obstacles such as billboards and water tanks have been installed on the roof, so there is no space to relocate the lifting device, making it impossible to use it. Furthermore, as shown in Figure 3, when multiple outdoor units are installed close to each other on the roofs of adjacent buildings and some of them are to be replaced, there is no space between the adjacent buildings and there is no space around the outdoor units, and if obstacles such as the water tanks are installed, the removal, removal and replacement of the outdoor units becomes even more difficult.

[0009] Furthermore, when lifting or unloading heavy items such as electrical equipment or outdoor units onto a stepped floor formed over several levels inside a tall building such as a warehouse or factory, there is a lot of existing equipment inside the building, and preparatory measures must be taken to avoid or dismantle this equipment, making it even more difficult to deal with the situation by installing the above-mentioned conventional lifting device, or even completely impossible.

[0010] Therefore, an object of the present invention is to provide a method for transporting heavy objects to be installed on the roof of a building or inside a factory, which can be carried out at a lower cost without using a lifting device that requires manufacturing costs because it must be assembled using the above-mentioned specially designed components, and which can be easily carried out even in cases where sufficient space cannot be secured around the building, where work space cannot be secured on the roof, or where the object is inside a factory, warehouse, or the like that has a lot of existing equipment. [Means for solving the problem]

[0011] In order to solve the above problems, the present invention is configured as follows. That is, the method for carrying in or carrying out a heavy object according to the present invention is a method for starting carrying in or carrying out a heavy object using scaffolding materials used at a construction site. end A designated place Surrounded by Reaching the roof of a building or a floor of a specified height inside a room It serves as a work enclosure Assembling the first scaffolding, Using the scaffolding material, Top of the first scaffolding Connect to the work enclosure. Heavy items are delivered Or the designated date for the start of removal To the upper area of ​​the place It forms a work enclosure that extends from the top of the work area to the area surrounding the designated area where loading and unloading will end or start. The second foothold Group Stand up, The internal spaces of the first and second work enclosures are formed to communicate from a predetermined location where the loading of heavy objects starts or the loading of heavy objects ends to a predetermined location where the loading of heavy objects ends or the loading of heavy objects starts, Located directly above the designated location where the heavy goods will start being brought in or end being taken out From the top of the first scaffold For work reaching the top of the second scaffold located directly above the designated location where the heavy object will be loaded or unloaded. An arm rail member is provided along the upper portion of the enclosure; A winch is provided on the rail portion of the arm rail member that is horizontally movable and capable of lifting and lowering a suspended load, The above The winch is attached to the first scaffold. The scaffold moves horizontally to the top located directly above the loading start location, then moves down to the heavy object prepared at the loading start location, and then moves along the work enclosure of the first scaffold with the heavy object suspended by the winch. The load is lifted to the top of the first scaffolding, then , the winch The second foothold Move horizontally along the work enclosure to the top of the loading end location, then move along the work enclosure from this top to the designated loading end location. Unload or Or, the winch is placed at the starting point of carrying out the heavy load from the second scaffold. Located directly above To the top horizontal move death, Heavy objects prepared at the starting point of removal and then hoisting the heavy object by the winch along the work enclosure of the second scaffolding to the top of the second scaffolding, after that , along the work enclosure of the second scaffolding First Foothold Located directly above the loading start area Move horizontally to the top Then, from the top of this scaffold to the designated location where removal will be completed, the work enclosure of the first scaffold is followed. The feature of this method is that it is done in a similar manner to unloading a load. Effect of the Invention

[0012] According to the method of the present invention for transporting heavy objects, first and second scaffoldings that serve as work enclosures for transporting and moving heavy objects are assembled using scaffolding materials commonly used at conventional construction sites, and an arm rail member is attached along the top of the assembled enclosure of the second scaffolding, and a winch is provided on this arm rail member to prepare for work.Therefore, compared to the case where a lifting device that was constructed as a conventional dedicated machine is used, most of the parts used can be constructed from existing materials, and the equipment costs required for the entire work can be significantly reduced.

[0013] In addition, even if a conventional lifting device is installed in a place where a crane cannot enter or where the working radius of the crane is beyond the reach of the crane, and there is no minimum space required for the installation, the work can be carried out using existing scaffolding materials. for Since the enclosure frame is assembled, a wide variety of assembly materials are available and can be selected according to the characteristics of the site. In addition, since the assembly methods are already well-established, assembly work can be easily performed even at sites where conventional equipment would be difficult. Furthermore, if the work is performed by an experienced scaffolding assembler, the time required for the entire work can be significantly reduced.

[0014] Furthermore, even if there is existing equipment that acts as an obstacle in the area where the second scaffolding is assembled, leading to the end position of the heavy object delivery or the start position of the heavy object delivery, by selecting scaffolding materials, it is possible to avoid this and extend the second scaffolding, which appears to be a third or fourth scaffolding, and assemble it.This makes it easy to prepare for assembly work, especially when the object to be transported is one out of several, or inside a factory or warehouse where there is a lot of existing equipment that could become obstacles, and allows the heavy object delivery or removal work to be carried out smoothly. [Brief description of the drawings]

[Diagram 2]FIG. 1 is an explanatory diagram showing a case where a heavy object is carried onto an indoor floor having a step according to the present invention. [Diagram 3] This is an external view showing a situation where multiple outdoor units are installed on the roof of a building, which has previously been a problem. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0016] Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

[0017] FIG. 1 is an explanatory diagram showing a case where a heavy object 8 is delivered to a predetermined location on the roof of a building 1 by implementing the present invention. As shown in the figure, a heavy object 8 is delivered to a start location 2 along a side wall of the building 1. It serves as a work enclosure The first scaffolding 3 is being assembled. When the first scaffolding 3 is assembled to the top of the building 1, the top of the first scaffolding 3 will be the upper area of ​​the loading end location 7. , and then loading end location 7 reach It serves as a work enclosure The second scaffold 4 is connected, extended and assembled, The internal space of the work enclosure of the first scaffolding 3 and the second scaffolding 4 is formed so as to communicate from the heavy load carrying start location 2 to the carrying end location 7 .

[0018] The assembly work of the first scaffolding 3 and the second scaffolding 4 can be done quickly and easily by assembling the wedge-tightened scaffolding using basic components such as posts with fastening parts, fabric materials, arm timbers, brackets, screw-tube jack-type base fittings, wall ties, scaffolding diagonals, and braces. The reason for adopting this scaffolding method is that the assembly components are modularized, assembly can be done with just a hammer, installation and dismantling are relatively easy, durability is high, and it is also cost-effective.

[0019] In addition, the second scaffold 4, which reaches from the top of the first scaffold 3 to the upper area of ​​the loading end position 7, For workAn arm rail member 5 is provided along the top of the enclosure, and this arm rail member 5 is provided with a winch 6 that can move the rail portion horizontally and lift and lower a suspended load. In order to implement the present invention, it is necessary to prepare the arm rail member 5 and winch 6 separately, but these members can also be existing ones and are not specially designed and manufactured, so that the work can be carried out easily. for The overall equipment costs, including the cost of materials required for assembling the enclosure, can be kept low.

[0020] As described above, the first scaffold 3 and the second scaffold 4 are assembled. The internal space of the work enclosure of the first scaffolding 3 and the second scaffolding 4 is formed so as to communicate from the heavy load carrying start location 2 to the carrying end location 7. As shown in the figure, the preparation for the loading work is completed. The loading work is performed by moving the winch 6 along the arm rail member 5 to the top of the first scaffold 3, and lifting the heavy load 8 prepared at the loading start location 2 to the top of the first scaffold 3. Along the inside of the work enclosure The load is lifted to the top, and then the winch 6 is moved to the upper area of ​​the second scaffold 4, which is the loading end location 7. Along the inside of the work enclosure After horizontal movement, heavy load 8 Along the inside of the work enclosure of the second scaffold 4 The delivery work is completed by unloading the goods at delivery completion location 7.

[0021] Conversely, the work of removing and transporting heavy objects 8 installed on the roof is carried out by assembling the first scaffolding 3 and the second scaffolding 4 in the same manner as above, setting the loading end location 7 for loading as the loading start location, moving the winch 6 to the top of the second scaffolding 4 where the loading start location is, and lifting the heavy object 8 prepared at the loading start location as a suspended load, and then moving horizontally to the top of the first scaffolding 3, and unloading the object, setting the loading start location 2 for loading as the loading end location, thereby completing the removal work.

[0022] In this way, according to the method for carrying in or carrying out a heavy object according to the present invention, the work can be performed using existing scaffolding assembly materials. forSince the enclosure frame is assembled, there is a wide variety of assembly materials, and materials can be selected according to the characteristics of the site. The assembly method is already well-established, so it is easy to carry in and out heavy objects even at sites where it is difficult to do so with conventional equipment. Also, as mentioned above, most of the parts used can be made from existing materials, which greatly reduces the equipment costs required for the entire operation. for If the scaffolding that forms the enclosure is assembled by an experienced person, the time required for the entire work can be significantly reduced.

[0023] FIG. 2 is an explanatory diagram that explains the case where, by implementing the present invention, a heavy object is carried in or out of a building with a high indoor space, such as a factory, warehouse, or school gymnasium, to a floor with a step. It shows that the work can be performed in exactly the same procedure as in FIG. 1, and the same symbols as in FIG. 1 indicate the same things.

[0024] As shown in the figure, a first scaffold 3 is assembled along the side wall of a stepped floor 11 in a building 10 such as a factory, until it exceeds the top of the stepped floor 11, and a second scaffold 4 is assembled by connecting and extending it from the top of the first scaffold 3 to the upper area of ​​the loading end location 7. The loading or unloading work of the heavy load 8 can be performed in exactly the same manner as the embodiment shown in FIG. 1. In particular, when the work is performed inside a building 10 such as a factory or warehouse that has many existing facilities that can become obstacles, the second scaffold can be extended and assembled as a third and fourth scaffold in appearance so as to avoid obstacles by selecting scaffolding materials when assembling the first scaffold 3 and the second scaffold 4, so that the loading and unloading work of the heavy load can be easily performed at a site with many obstacles that cannot be performed using conventional devices.

[0025] Furthermore, according to the method of the present invention, even in a situation where a plurality of outdoor units 20 are installed close to each other on the rooftop as shown in FIG. 3, there is no space around the outdoor units 20, and obstructing facilities such as water tanks are installed, and some of the outdoor units 20 need to be removed and replaced, it is possible to easily carry in and out heavy objects. [Industrial Applicability]

[0026] The method of transporting or unloading heavy objects according to the present invention can form a work enclosure using existing scaffolding materials for the start and end locations for the heavy object, and if the arm rail member for moving the winch can be properly installed in the work enclosure taking into account the site conditions, it can make it possible to transport or unload heavy objects even at sites where it would be difficult to do so with conventional equipment, thereby providing a highly versatile method with a wide range of implementation.
