Description

The present invention relates to a transport device for transporting installation objects such as air conditioners and various types of piping to an installation site in a building under construction.

In a building, an air conditioner as disclosed in Patent Document 1, for example, is installed in the ceiling space of the lower floor on the lower surface side of the upper floor slab. This air conditioner has a configuration in which a blow-off chamber and an intake chamber are assembled in the front-rear direction of the air conditioner main body. The air conditioner, in which the blow-off chamber and the intake chamber are assembled in the front-rear direction of the air conditioner main body, is installed in a suspended state in the ceiling space.

Conventionally, in the work of installing an air conditioner as described above, the work of assembling the blowout chamber and the intake chamber to the air conditioner main body was generally performed at the installation site of the air conditioner. However, the work of assembling the chamber is complicated and requires skill. This is a factor that reduces work efficiency at the installation site. For example, at a new construction site, the construction period for installing an air conditioner on each floor is predetermined. It becomes difficult to finish the work. Furthermore, in recent years, it has become difficult to secure workers at construction sites, so it is desired to reduce the work at installation sites.

Therefore, it has been proposed that the chamber assembly work, which was conventionally done at the installation site, be performed in advance at a factory, and the air conditioner with the chamber assembled thereon be transported from the factory to the installation site. For example, in Patent Document 2, an air conditioner is manufactured in a factory by assembling a blowout chamber and an intake chamber in the front-rear direction of the air conditioner body, and further assembling a frame that integrally holds the air conditioner body and the chamber. However, it is proposed that the equipment be transported from the factory to the installation site.

Patent No. 6709485 JP2021-76367A

By the way, when the blow-off chamber and the intake chamber are assembled in the front-rear direction of the air conditioner main body, the planar size of the air conditioner increases. On the other hand, some temporary elevators installed at construction sites for transporting materials are narrow, with a width of only about 1 meter. Further, among the passages on each floor, there may be narrow passages whose width is only about 1 meter. Therefore, once the chamber is assembled into the air conditioner main body at the factory, the problem becomes how to transport it through such a narrow space as described above.

In response to this problem, Patent Document 2 proposes that an air conditioner having chambers assembled in the front-rear direction be placed on a trolley not in a horizontal position but in a vertical position with the left and right sides facing up and down. By placing the air conditioner in a vertical position, it is possible to reduce the plane size occupied by the air conditioner. Therefore, the air conditioner can be transported even in a narrow space such as the one described above.

On the other hand, when transporting an air conditioner from a factory to a construction site, if the air conditioner is loaded onto a transport vehicle in a vertical position, internal refrigerant piping, heat exchangers, etc. may be damaged due to vibration during transport. There is sex. In order to prevent this, when transporting the air conditioner from the factory to the construction site, it is desirable to load the air conditioner onto the transport vehicle in a horizontal position.

Therefore, if an attempt is made to transport the air conditioner in a narrow space at a construction site using a trolley as in Patent Document 2, the air conditioner, which is brought in in a horizontal position, must be transferred to the trolley at the construction site. In this case, the work of reloading the air conditioner onto the trolley requires a work space that is at least equal to the planar size of the air conditioner in a horizontal position and the planar size of the trolley. However, depending on the construction site, it may be difficult to secure sufficient work space in addition to space to temporarily store cargo loaded onto transport vehicles. In such a case, there is a problem in that it is extremely difficult to convert the horizontal air conditioner, which is unloaded from the transport vehicle, into a vertical position and then transfer it to a trolley at a construction site.

Furthermore, the above-mentioned problem is not limited to air conditioners, but also applies to various types of piping such as refrigerant piping and steel pipes, items that exceed a certain size, or heavy items that cannot be lifted by workers by hand. This problem can similarly occur with all objects to be installed inside a building under construction.

Therefore, the present invention has been made to solve the above problems, and eliminates the need for the above-mentioned remounting work, and can be suitably used when transporting an installation target installed in a building under construction to an installation site. The purpose is to provide a conveying device that can

This transport device 1 is for transporting a ceiling-suspended air conditioner 50, which is an installation object 9, to an installation site. Further, the transport device 1 is configured to be able to load and transport a plurality of air conditioners 50A, 50B. In this embodiment, the direction parallel to the X-axis shown in FIG. 1 is defined as the left-right direction of the air conditioners 50A, 50B, and the direction parallel to the Y-axis is defined as the front-back direction of the air conditioners 50A, 50B.

FIG. 2 is a diagram showing a configuration example of the air conditioners 50 (50A, 50B) transported by the transport device 1. The air conditioner 50 includes an air conditioner main body 60, a blowout chamber 70, and an intake chamber 80. That is, the air conditioner 50 is configured by assembling the blow-off chamber 70 and the intake chamber 80 in the front-rear direction (Y direction) of the air conditioner main body 60.

A mounting portion 61 for mounting the blow-off chamber 70 is provided on the front side of the air conditioner main body 60. For example, the mounting portion 61 has a shape in which the peripheral edge of an air outlet formed on the front side of the air conditioner main body 60 protrudes toward the front side in the shape of a sleeve. On the other hand, a similar mounting portion is provided on the surface (rear surface) of the blow-off chamber 70 facing the air conditioner main body 60. The blow-off chamber 70 is assembled to the front side of the air conditioner main body 60 by fitting the mounting portion of the blow-off chamber 70 into the mounting portion 61 of the air conditioner main body 60 and driving a number of screws around the mounting portion 61.

The connecting portion 12 is formed of a shaped steel or a steel pipe, is arranged to cross between the two supporting portions 11, 11, and has both ends connected to the two supporting portions 11, 11. Further, the connecting portion 12 is provided with a rotating shaft 14 protruding from the surface opposite to the surface facing the air conditioners 50A, 50B. This rotating shaft 14 has a shaft portion 14a having a predetermined outer diameter and a head portion 14b having a larger diameter than the shaft portion 14a. Further, the connecting portion 12 is provided with a first rotation restricting portion 16 at a position spaced apart from the rotating shaft 14 by a predetermined distance toward the rear side (+Y direction side). For example, the first rotation regulating section 16 is configured by a hole 16a that fits into a rod-shaped body 37 of the posture holding section 34, which will be described later. Further, the connecting portion 12 is provided with a stopper 18 that restricts the rotation of the support member 2a at a position spaced apart from the rotating shaft 14 by a predetermined distance toward the front side (-Y direction side).

Further, a metal plate 15 is attached to the connecting portion 12, and a second rotation regulating portion 17 is provided at the tip of the metal plate 15. For example, like the first rotation restriction part 16, the second rotation restriction part 17 is constituted by a hole 17a that fits into a rod-shaped body 37 of the posture holding part 34, which will be described later. The first rotation restriction portion 16 and the second rotation restriction portion 17 are provided on concentric circles centered on the rotation axis 14, and are provided at positions forming an angle of about 90 degrees with each other. Although the support member 2a has been described here, the support member 2b also has a similar configuration.

Returning to FIG. 3, the trolley 3 includes a base 20 and a pair of support columns 24a and 24b that stand up from the base 20 and face each other. The base 20 includes a pair of movable bases 21, 21 having wheels 22 attached to their lower surfaces, and a pair of connecting bases that connect the pair of movable bases 21, 21 parallel to each other at a predetermined distance apart. It is equipped with stands 23, 23. The base 20 is formed into a substantially rectangular shape in plan view by assembling a pair of movable bases 21, 21 and a pair of connecting bases 23, 23. Further, among the two connecting bases 23, 23 provided on the base 20, one connecting base 23 is removable from the base 20. When one connecting base 23 is removed from the trolley 3, the base 20 assumes a substantially U-shape in plan view. Note that the length of the connecting bases 23, 23 is slightly larger than the length of the air conditioner 50 in the left-right direction.

The support columns 24a and 24b are provided at the center of the movable bases 21 and 21 in the longitudinal direction. An air conditioner 50 can be placed in the space between the pair of support columns 24a, 24b. A metal chain 25 supported by a pulley is disposed inside the support columns 24a, 24b. This chain 25 supports an elevating member 26 so as to be movable up and down in the vertical direction along the support sections 24a and 24b. Further, the chain 25 is connected to a winding section (not shown) which is rotated by an operation handle 27 which can be rotated. Therefore, for example, by rotating the operating handle 27 in a predetermined direction, the winding section winds up the chain 25 in a predetermined direction, and the elevating member 26 can be raised along the support columns 24a and 24b. Further, by rotating the operating handle 27 in the opposite direction to the predetermined direction, the winding section winds up the chain 25 in the opposite direction, and the elevating member 26 can be lowered along the support columns 24a and 24b. In other words, the operating handle 27 and the chain 25 are provided as a lifting drive unit that moves the lifting member 26 up and down in the vertical direction. Although the elevation drive unit of this embodiment is configured as a manual drive unit, it is not limited to this, and may be configured as an electric drive unit. do not have.

The support columns 24a and 24b are arranged on the base 20 with the elevating members 26 and 26 facing each other. The elevating member 26 of the support column 24a is provided with a holding portion 30a that engages with the support member 2a and holds the air conditioners 50A, 50B. Further, the elevating member 26 of the support column 24b is provided with a holding portion 30b that engages with the support member 2b and holds the air conditioners 50A, 50B. These two holding parts 30a and 30b have a symmetrical structure with respect to the center line M of the cart 3 in the left-right direction (X direction).

FIG. 5 is an enlarged view showing the holding portion 30a provided on the support portion 24a. As shown in FIG. 5A, the holding part 30a is fixed to the upper part of the elevating member 26, and moves up and down integrally with the elevating member 26. The holding portion 30a has a locking plate 32 that stands up along the front-rear direction (Y direction) of the truck 3. A bearing portion 31 that holds the rotating shaft 14 of the support member 2a is provided at the center of the locking plate 32. For example, the bearing portion 31 is formed as a U-shaped cutout in the locking plate 32. The width of this notch is larger than the outer diameter of the shaft portion 14a of the rotating shaft 14 and smaller than the outer diameter of the head 14b. Therefore, the bearing part 31 can hold the shaft part 14a of the rotating shaft 14.

Further, the locking plate 32 is provided with a posture holding portion 34 at a position separated from the bearing portion 31 by a predetermined distance toward the rear side (+Y direction side) of the air conditioner 50. The posture holding section 34 has a lever holding plate 36 that is parallel to the locking plate 32. The posture holding part 34 has a rod-shaped body 37 that is inserted into a hole 35 formed in the locking plate 32 and a hole formed in the lever holding plate 36. This rod-shaped body 37 is provided with a flange portion 38 , and a coil spring 39 is arranged between the flange portion 38 and the lever holding plate 36 . An operating lever 40 is attached to the base end of a rod-shaped body 37 that projects outward from the lever holding plate 36. The attitude holding section 34 configured in this manner is arranged such that the tip of the rod-shaped body 37 is projected from the hole 35 of the locking plate 32 by the biasing force of the coil spring 39. As shown in FIG. 5(b), when the operating lever 40 is pulled in the direction of arrow F1 against the biasing force of the coil spring 39, the posture holding section 34 connects the tip of the rod-shaped body 37 to the locking plate 32 and the lever. It is in a retracted state between it and the holding plate 36. The posture holding section 34 having such a configuration allows the support member 2a to be fixed by engaging the tip of the rod-shaped body 37 with the first rotation restriction section 16 or the second rotation restriction section 17 of the support member 2a. Rotation around the rotating shaft 14 is restricted to maintain the posture of the air conditioners 50A, 50B.

Next, an example in which the air conditioners 50A and 50B are loaded on the transport device 1 will be described. When loading the air conditioners 50A, 50B onto the transport device 1, first arrange the air conditioners 50A, 50B in the vertical direction, and place the support members 2 on both left and right sides 63, 64 of the air conditioners 50A, 50B.

At this time, the bearing portion 31 is inserted between the head portion 14b of the rotating shaft 14 and the connecting portion 12. Therefore, the rotating shaft 14 is held by the holding part 30a without detaching from the holding part 30a.

Furthermore, when inserting the rotating shaft 14 into the bearing portion 31, the operating lever 40 is pulled in the direction of the arrow F1 as shown in FIG. As a result, the tip of the rod-shaped body 37 provided on the posture holding part 34 is pulled in the direction of arrow F1, so that the rotating shaft 14 can be smoothly inserted into the bearing part 31 without the tip of the rod-shaped body 37 hitting the support member 2a. be able to. When the rotating shaft 14 can be inserted into the bearing portion 31, the operation of pulling the operating lever 40 in the direction of the arrow F1 is stopped. Thereby, the rod-shaped body 37 protrudes from the locking plate 32 toward the support member 2a due to the biasing force of the coil spring 39. Then, when the position of the hole 16a of the first rotation regulating part 16 provided in the connecting part 12 of the support member 2a is lowered to the position of the tip of the rod-shaped body 37, the tip of the rod-shaped body 37 is fitted into the hole 16a. . As a result, the support member 2a is in a state where the two positions of the rotation shaft 14 and the first rotation restriction portion 16 are locked with the holding portion 30a, and rotation around the rotation shaft 14 is restricted. Ru. Further, at this time, the stopper 18 is also in a state joined to the locking plate 32, and the posture of the support member 2a is maintained. Although FIG. 8 shows the relationship between the holding part 30a and the support member 2a, the relationship between the holding part 30b and the support member 2b is also the same.

FIG. 9 is a diagram showing a state (horizontal posture) in which the support members 2a, 2b are supported by the holding parts 30a, 30b, and the air conditioners 50A, 50B are loaded on the transport device 1. When the support members 2a, 2b are supported by the holding parts 30a, 30b as described above, the air conditioners 50A, 50B are placed in a horizontal position with the support parts 24a, 24b at a predetermined height, as shown in FIG. held in position. At this time, since the rod-shaped body 37 of the posture holding part 34 is engaged with the hole 16a of the first rotation restriction part 16, the support members 2a and 2b are prevented from rotating around the rotation axis 14. The horizontal posture of the air conditioners 50A and 50B is maintained.

When moving the transport device 1 while holding the air conditioners 50A, 50B in a horizontal position, the air conditioners 50A, 50B are lowered by rotating the operating handles 27 provided on the support columns 24a, 24b. let That is, as shown in FIG. 1, by lowering the air conditioners 50A and 50B to positions close to the trolley 3, the center of gravity of the transport device 1 is lowered. Thereby, the transport device 1 can stably hold the air conditioners 50A and 50B. Furthermore, by lowering the center of gravity of the transport device 1, vibrations of the air conditioners 50A and 50B can be suppressed when the transport device 1 is moved by rolling the wheels 22. The work of loading the air conditioners 50A, 50B onto the transport device 1 in this manner is performed at a factory.

As shown in FIG. 1, the transport device 1 holding the air conditioners 50A and 50B in a horizontal position is loaded onto a transport vehicle and transported from the factory to the building where the installation site is located. At this time, since the transport device 1 holds the air conditioners 50A, 50B in a horizontal position, the air conditioners 50A, 50B will not be damaged even if relatively large vibrations are applied during transport. Further, since the center of gravity of the transport device 1 holding the air conditioners 50A and 50B is low, the transport device 1 will not overturn even if it is loaded onto a transport vehicle and transported. Therefore, the transport device 1 can simultaneously and safely transport the two air conditioners 50A and 50B from the factory to the building where the grounding site is located.

When the transport vehicle arrives at the building where the installation site is located, the transport device 1 holding the air conditioners 50A and 50B in a horizontal position is unloaded from the transport vehicle. Then, by grounding the wheels 22 provided on the cart 3 of the transport device 1 and moving the cart 3, the transport device 1 is transported to the installation site.

When transporting the transport device 1 holding the air conditioners 50A and 50B to the installation site at a construction site, the transport device 1 is placed on a temporary elevator for carrying in materials and transported to the floor where the installation site is located. Sometimes. Further, the conveying device 1 may have to pass through a narrow passage. Therefore, when transporting the transport device 1 unloaded from the transport vehicle to the installation site, it is necessary to normally pass through the narrow space as described above.

In the conveyance device 1 of this embodiment, the holding parts 30a and 30b rotatably support the support members 2a and 2b around the rotation shaft 14. Therefore, the conveyance device 1 can change the attitude of the air conditioners 50A, 50B from a horizontal attitude to an upright attitude by rotating the support members 2a, 2b with respect to the holding parts 30a, 30b. In order to perform such an attitude change, first, as shown in FIG. 1, the air conditioners 50A, 50B in a horizontal attitude are lowered to a position close to the trolley 3 and then lifted up. That is, by rotating the operating handles 27 provided on the support columns 24a, 24b, the air conditioners 50A, 50B are lifted to a predetermined height position as shown in FIG. Then, by pulling in the operating lever 40, the state in which the posture holding section 34 is engaged with the first rotation regulating section 16 is released. As a result, the state in which the air conditioners 50A and 50B are held in a horizontal position is released. Then, the air conditioners 50A and 50B supported by the support members 2a and 2b become rotatable in the direction of arrow R about the rotating shaft 14, and change their posture from a horizontal posture to an upright posture.

FIG. 10 is a diagram showing the air conditioners 50A, 50B in an upright position. As shown in FIG. 10, the air conditioners 50A and 50B are rotated about 90 degrees around the rotation shaft 14 from a horizontal position, thereby assuming an upright position with the blow-off chamber 70 and the intake chamber 80 arranged vertically. Further, by rotating the support members 2a and 2b by approximately 90 degrees, the second rotation regulating portion 17 provided on the metal plate 15 rotates to the position of the posture holding portion 34. As a result, the tip of the rod-shaped body 37 of the posture holding section 34 fits into the hole 17a provided in the second rotation regulating section 17. As a result, the support members 2a and 2b are engaged with the holding parts 30a and 30b at two positions, the rotation shaft 14 and the second rotation restriction part 17, and rotate about the rotation shaft 14. things are regulated. That is, the transport device 1 can hold the air conditioners 50A and 50B in an upright position. The transport device 1 can move while holding the air conditioners 50A and 50B in an upright position.

The standing posture shown in FIG. 10 is a vertical posture in which the front and rear surfaces of the air conditioner main body 60 to which the blow-off chamber 70 and the like are assembled are directed upward and downward. For example, there are models of the air conditioner main body 60 in which internal refrigerant piping, heat exchangers, etc. are damaged if the air conditioner main body 60 is placed vertically with left and right sides facing up and down. On the other hand, the conveyance device 1 of the present embodiment is in a standing posture with the front and rear surfaces of the air conditioner main body 60 facing up and down, rather than the left and right side surfaces of the air conditioner main body 60 facing up and down. Therefore, even if the transport device 1 is moved in the upright position shown in FIG. 10, the vibrations during transport may damage the refrigerant pipes, heat exchanger, etc. provided inside the air conditioner main body 60. Never. Therefore, by moving the conveyance device 1 in the state shown in FIG. 10, it is possible to normally pass through the above-mentioned narrow place without damaging the air conditioners 50A, 50B.

Moreover, in the standing position shown in FIG. 10, the blow-off chamber 70 and the intake chamber 80 are held in a state floating above the floor surface. Therefore, it is possible to suppress excessive loads from being applied to each of the blow-off chamber 70 and the intake chamber 80. Therefore, it is possible to prevent the fragile blow-off chamber 70 and intake chamber 80 from being deformed and damaged.

In this way, the transport device 1 can easily change the posture of the air conditioners 50A, 50B from a horizontal position to an upright position while holding the air conditioners 50A, 50B, and allow the air conditioners 50A, 50B to pass through narrow places such as temporary elevators and passageways. is possible. Therefore, there is no need to unload the air conditioners 50A, 50B from the conveyance device 1 when passing through a narrow place, and the conveyance efficiency is excellent. After passing through the narrow area, the posture of holding the air conditioners 50A and 50B is returned from the standing posture to the horizontal posture, and the conveying device 1 is moved with the center of gravity lowered as shown in FIG. Also good.

Furthermore, when the transport vehicle arrives at the building where the installation site is located and is unloaded from the transport vehicle, the transport device 1 changes the attitude of the air conditioners 50A and 50B from a horizontal position to an upright position, thereby unloading the air conditioners from the transport vehicle. It also has the advantage of being easier to perform. As described above, the transport device 1 transported by the transport vehicle holds the air conditioners 50A and 50B in a horizontal position. Therefore, the planar size of the transport device 1 that holds the air conditioners 50A and 50B is large, and when an attempt is made to unload the transport device 1 from the transport vehicle using a forklift, the transport device 1 is held in a stable state by the forklift. Difficult to support. In such a case, the plane size of the transport device 1 can be reduced by changing the holding posture of the air conditioners 50A, 50B by the transport device 1 from a horizontal position to an upright position, so that the forklift can hold the transport device 1. It will be possible to support it in a stable state and unload it from the transport vehicle normally. Furthermore, even if the transport vehicle is equipped with a lifting device such as Power Gate (registered trademark), the transport device 1 can be placed on the lifting device by changing the air conditioners 50A and 50B to the standing position. This also has the advantage that the transport device 1 can be safely and efficiently unloaded from the transport vehicle. Therefore, even when the transport device 1 is unloaded from the transport vehicle, the postures of the air conditioners 50A and 50B may be changed from the horizontal posture to the upright posture. After the transport device 1 is unloaded from the transport vehicle with the air conditioners 50A and 50B in the upright position, the air conditioners 50A and 50B are transported in the upright position until they arrive at the installation site. You can also do it.

When the transport device 1 arrives at the installation site, the work of unloading the air conditioners 50A and 50B from the transport device 1 is performed. However, at a construction site, there may be no elevator such as a forklift on each floor where the air conditioners 50A and 50B are installed. In that case, the air conditioners 50A and 50B can be unloaded from the transport device 1 by preparing another trolley 5 in addition to the transport device 1.

FIG. 11 is a diagram showing an example in which the air conditioners 50A and 50B are unloaded from the transport device 1 using another trolley 5. First, when unloading the air conditioners 50A, 50B from the transport device 1, as shown in FIG. raise to position. Also, at this time, one connecting base 23 is removed from the truck 3, and the base 20 is shaped into a substantially U-shape in plan view. Then, as shown in FIG. 11(b), the trolley 5 is inserted between the support columns 24a and 24b of the transport device 1. Thereby, the trolley 5 is located below the air conditioner 50B. Then, the air conditioners 50A, 50B are lowered while simultaneously rotating the operating handles 27, 27 provided on the support columns 24a, 24b. Thereby, as shown in FIG. 11(c), the cart 5 can support the lower surface of the air conditioner 50B. When the trolley 5 supports the lower surface of the air conditioner 50B, the connection parts 65, 65 on both left and right sides 63, 64 of the air conditioner 50B and the mounting parts 13b, 13b of the support members 2a, 2b are fixed. Remove the bolts and nuts that are attached to the air conditioner 50B to release the state in which the air conditioner 50B is supported by the support members 2a and 2b. Thereafter, when the operating handle 27 is rotated to raise the support members 2a and 2b, only the air conditioner 50A is raised and the air conditioner 50B is placed on the trolley 5, as shown in FIG. 11(d). remain in the state. Therefore, as shown in FIG. 11(e), by pulling out the cart 5 inserted between the support columns 24a and 24b, it is possible to take out the air conditioner 50B, and the air conditioner 50B can be removed from the transport device 1. You can take it down. Subsequently, when removing the air conditioner 50A from the transport device 1, the same operations as described above may be repeated.

Thereafter, each of the air conditioners 50A and 50B removed from the transport device 1 is lifted to a position near the lower surface of the upper floor slab, and hanging bolts are connected and fixed to the connecting parts 65 and 65 on both left and right sides 63 and 64. The air conditioners 50A and 50B are installed in a suspended state in the ceiling space. With the above steps, the work of installing the air conditioners 50A and 50B is completed.

In this way, the transport device 1 of this embodiment can be suitably used when transporting the ceiling-suspended air conditioner 50 to an installation site. In particular, this conveying device 1 is attached to both left and right side surfaces 63, 64 of the air conditioner 50, supports the air conditioner 50, and engages with the support members 2a, 2b to support the air conditioner 50. The air conditioner 50 has holding parts 30a and 30b that hold the air conditioner 50, and a cart 3 that is movable while holding the air conditioner 50. The holding parts 30a and 30b hold the support members 2a and 2b rotatably about a rotation axis 14 that is perpendicular to both left and right side surfaces 63 and 64 of the air conditioner 50, and The configuration allows the posture to be changed between a horizontal posture and an upright posture. According to such a configuration, the conveyance device 1 can appropriately change the posture of the air conditioner 50, in which the blowout chamber 70 and the intake chamber 80 are assembled to the air conditioner main body 60, between the horizontal posture and the upright posture. It is possible to do so. Therefore, if it is necessary to transport the air conditioner 50 in a narrow temporary elevator at a construction site, the air conditioner 50 can be transported while being held in an upright position. Further, even when it is necessary to transport the air conditioner 50 through a narrow passage to the installation site, the air conditioner 50 can be transported while being held in an upright position.

Furthermore, as described above, the air conditioner 50 is in the standing position with the front and rear surfaces of the air conditioner main body 60 facing up and down, so even if the conveying device 1 is moved in the standing position, The refrigerant piping, heat exchanger, etc. provided inside the air conditioner main body 60 will not be damaged due to vibrations during transportation. That is, the transport device 1 of this embodiment can appropriately transport the air conditioner 50 from the factory to the installation site without damaging the air conditioner 50. Therefore, it is possible to assemble the blow-off chamber 70 and the intake chamber 80 to the air conditioner main body 60 in advance at the factory, and then appropriately transport the air conditioner 50 created by this process to the installation site. This has the advantage of reducing the work burden at the installation site.

In particular, the transport device 1 of the present embodiment can transport the air conditioner 50 with the air conditioner 50 mounted thereon until it arrives at the installation site after the air conditioner 50 is mounted in a horizontal position at the factory. . Therefore, there is no need to remount the air conditioner 50 between the factory and the installation site, resulting in excellent transport efficiency.

In addition, in the above, the case where the conveyance apparatus 1 is mainly used when conveying the air conditioner 50 from a factory to an installation site was illustrated. However, the present invention is not limited to this, and the above-described transport device 1 may be used only at construction sites. That is, the above-described transport device 1 is prepared at a construction site, and when transporting the air conditioner 50 that has been transported from the factory to the construction site to the installation site, the air conditioner 50 is loaded onto the transport device 1 and transported. It is also possible to transport the air conditioner 50 to the installation site while utilizing the posture change function of the air conditioner 50 by the device 1.

Moreover, although the example of a structure in which the conveyance apparatus 1 can load two air conditioners 50A and 50B was demonstrated above, it is not restricted to this. That is, the transport device 1 may adopt a configuration in which only one air conditioner 50 can be loaded, or may adopt a configuration in which three or more air conditioners 50 can be loaded.

Next, a second embodiment of the present invention will be described. In this embodiment, a piping unit 101 holding a plurality of piping is illustrated as an installation target 9 installed inside a building under construction, and a transport device used to transport the piping unit 101 to an installation site. 1 will be explained. Moreover, the conveyance device 1 of this embodiment can also be used when installing the piping unit 101 at an installation target location.

FIG. 12 is a perspective view showing the piping unit 101 to be transported by the transport device 1 in this embodiment. This piping unit 101 is a unit in which a plurality of pipes (vertical pipes) arranged vertically across a plurality of floors of a building are aggregated, and a plurality of pipes can be installed on each floor. For example, the piping unit 101 can be installed one floor at a time from the lower floor to the upper floor in a newly constructed building.

This piping unit 101 includes a pedestal 102 formed by assembling a plurality of steel materials such as angle iron and channel steel into a rectangular parallelepiped shape by welding or the like, and a plurality of piping 110 attached to the pedestal 102 and held by the pedestal 102. It is equipped with The pedestal 102 is configured as an earthquake-resistant pedestal that includes a box-shaped base portion 103 provided at the top and support portions 104 extending downward from the four corners of the lower surface of the base portion 103 . The plurality of pipes 110 are arranged in the vertical direction (vertical direction) at predetermined intervals inside the pedestal 102 and are installed so as to penetrate the upper and lower surfaces of the base portion 103. The upper portions of these plurality of pipes 110 are fixed to the base portion 103 and the lower portions are fixed to the support portion 104.

FIG. 13 is a perspective view showing the pedestal 102. The base portion 103 has an upper plate 125 in which a plurality of holes 127 are formed on the upper surface side. The base portion 103 also has a lower plate 126 on the lower surface side in which a plurality of holes 127 are formed at the same positions as the upper plate 125. The plurality of pipes 110 are inserted into a plurality of holes 127 formed in the upper plate 125 and the lower plate 126, and are installed so as to vertically penetrate inside the base portion 103.

Further, a flange portion 121 that protrudes in the horizontal direction is formed on the peripheral side surface of the base portion 103. The flange portion 121 is formed to protrude further outward than the peripheral edge of an opening 190 (see FIG. 16) formed in the frame (floor slab, etc.) on the floor to be installed among the plurality of floors. Further, the flange portion 121 is integrally formed with the base portion 103 and has sufficient strength to support the entire weight of the piping unit 101.

A pair of support walls 105, 105 made of, for example, channel steel are erected on both left and right sides of the upper plate 125 of the base portion 103 at a predetermined interval. A plurality of mounting fittings 108 are attached to the upper ends of the pair of support walls 105, 105 so as to cross the upper position of the upper plate 125 in the left-right direction. The mounting fitting 108 is a fitting for fixing the upper part of the pipe 110 to the base portion 103, and is made of, for example, an angle member having an L-shaped cross section. A plurality of holes 108a are formed in each of the plurality of mounting fittings 108 for attaching a U-shaped piping band 109 (see FIG. 12). The upper part of the piping 110 protruding upward from the hole 127 of the upper plate 125 is restrained by the piping band 109, and both ends of the piping band 109 are fixed to the hole 108a with bolts and nuts, so that the upper part of the piping 110 is attached to the base part 103. Fixed.

The support portion 104 has a plurality of pillars 106 extending downward from the four corners of the lower surface of the base portion 103 . The plurality of pillars 106 include, for example, pillars 106a and 106b arranged on both left and right front sides of the pedestal 102, and pillars 106b and 106c arranged on both left and right rear sides of the pedestal 102. Further, the support portion 104 has connecting portions 107, 107 extending in the front-rear direction at lower portions on both left and right sides of the pedestal 102. These connecting parts 107, 107 mutually connect the lower ends of columns 106a, 106c arranged at two places on the front and back on the left side of the pedestal 102, and connect the lower ends of columns 106b, 106d arranged at two places on the front and back on the right side of the pedestal 102. interconnect. In other words, the connecting parts 107, 107 are arranged parallel to each other at the lower end of the supporting part 104. A plurality of mounting fittings 108 are attached to the upper surface side of the connecting parts 107, 107 so as to cross the lower position of the base part 103 in the left-right direction. These plurality of fittings 108 are similar to the above-mentioned fittings 108 attached to the base portion 103, and are fittings for fixing the lower part of the pipe 110 to the support portion 104. That is, a plurality of holes 108a for attaching U-shaped piping bands 109 (see FIG. 12) are formed in each of the plurality of mounting fittings 108 that cross between the pair of connecting portions 107, 107. The lower part of the piping 110 extending downward from the base part 103 is restrained by the piping band 109, and both ends of the piping band 109 are fixed to the holes 108a with bolts and nuts, thereby fixing the lower part of the piping 110 to the support part 104. .

Further, the support portion 104 is provided with an attachment portion 122 at a predetermined height position of the support column 106 for attaching a first application tool 130, which will be described later. For example, the attachment portion 122 is formed as a hole into which a fastening member consisting of a bolt and a nut can be attached.

Further, the pair of support walls 105 provided on the base portion 103 are provided with mounting portions 123 at both end positions in the front-rear direction for mounting a second application tool 140, which will be described later. For example, the attachment portion 123 is formed as a hole into which a fastening member consisting of a bolt and a nut can be attached.

FIG. 14 is a diagram showing the internal structure of the base portion 103 with the piping 110 attached to the pedestal 102. As shown in FIG. 14, the piping 110 is installed so as to vertically penetrate the base portion 103. Further, inside the base portion 103, the gaps between the plurality of pipes 110 are filled with a noncombustible material 129. The noncombustible material 129 is used as a refrigerant coating copper pipe penetration treatment material, and includes, for example, a thermal expansion fireproof material, and has the property of thermally expanding due to high temperatures during a fire and completely concealing the inside of the base portion 103. have. This noncombustible material 129 closes the holes 127 in the upper plate 125 and the lower plate 126. In this way, the base portion 103 is subjected to fire prevention treatment by the non-combustible material 129 filled inside the base portion 103. Therefore, the base portion 103 has a fireproof structure.

FIG. 15 is a diagram showing a configuration example of the piping 110 installed on the pedestal 102. For example, the pipe 110 is formed by bundling together three refrigerant pipes 111, 112, and 113 for air conditioning. The refrigerant pipes 111, 112, and 113 are pipes for circulating refrigerant between an outdoor unit installed on the roof of a building and an air conditioner (for example, an indoor unit) installed on each floor. Therefore, the pipe 110 formed by bundling the refrigerant pipes 111, 112, and 113 into one is a pipe connected to an air conditioner installed on any floor of the building. In other words, the three refrigerant pipes 111, 112, 113 included in one pipe 110 are connected to the air conditioner on the same floor. The refrigerant pipes 111, 112, and 113 are all copper pipes, and their outer peripheral surfaces are covered with a cylindrical heat insulating material 114. Each of the refrigerant pipes 111, 112, 113 is formed in advance to have a length that is about the same as or shorter than the length from the floor to the ceiling of the floor to be installed, and is bundled together with an adhesive tape 118 or the like. Although the illustrated example shows a case where three refrigerant pipes 111, 112, and 113 are bundled into one, the number of refrigerant pipes to be bundled into one is not limited to three.

Further, an electric cable 116 is attached to the piping 110. Specifically, the pipe 110 has a structure in which a sleeve 115 through which an electric cable 116 can be inserted is bundled together with refrigerant pipes 111, 112, and 113. An electrical cable 116 is inserted into the sleeve 115 for transmitting and receiving electrical signals between an outdoor unit installed on the roof of the building and an air conditioner (for example, an indoor unit) installed on each floor. 110. As shown in the enlarged view A of FIG. 15, the upper end of the electric cable 116 extends upward from the upper end opening of the sleeve 115, and a connector 117a is attached to the tip thereof. Further, as shown in the enlarged view B of FIG. 15, the lower end of the electric cable 116 extends downward from the lower end opening of the sleeve 115. When the electric cable 116 is longer than the sleeve 115, it is preferable to hold the electric cable 116 in a wound state using a binding band or the like. A connector 117b is attached to the lower end of the electric cable 116.

On the pedestal 102, a plurality of pipes 110 having the above configuration are arranged in parallel in the left-right direction and the front-back direction. The plurality of pipes 110 are connected to air conditioners on different floors, respectively. Therefore, the pedestal 102 can hold a plurality of pipes 110 arranged on each of a plurality of floors.

The piping unit 101 as described above is assembled in a factory in the state shown in FIG. 12, transported to a construction site, and transported to the installation target floor using a temporary elevator installed at the construction site. In other words, the piping unit 101 can be transported to the installation target floor without using a crane installed during construction work, and therefore has excellent transport efficiency. When the piping unit 101 is transported to the installation target floor, it is installed at the installation location.

FIG. 16 is a diagram showing the concept of the construction method of the piping unit 101. As shown in FIG. 16, an opening 190 for passing vertical piping 110 is formed in a floor slab 180 of each floor of a building under construction. The piping unit 101 is installed on the floor slab 180 of the installation target floor by lowering it inside the opening 190. As described above, the flange portion 121 provided on the base portion 103 of the pedestal 102 is formed to protrude further outward than the peripheral edge of the opening 190. Therefore, when the piping unit 101 is lowered from above the opening 190 toward the inside of the opening 190, the flange portion 121 comes into contact with the periphery of the opening 190, and the piping unit 101 comes into contact with the base portion 103 fitted into the opening 190. Unit 101 may be installed on floor slab 180. Therefore, when lowering the piping unit 101 toward the opening 190, it is only necessary to lower the piping unit 101 until the flange portion 121 contacts the floor slab 180, so there is no need to perform delicate height adjustments of the piping unit 101. Work efficiency can be improved.

Here, in the example shown in FIG. 16, the lower end of the pipe 110 extends further downward than the lower end of the support column 106. Refrigerant pipes 111, 112, and 113 included in pipe 110 are fragile and easily damaged. Therefore, if the lower end of the piping 110 extends further downward than the lower end of the support column 106 as shown in FIG. It is necessary to install it on the target floor.

Therefore, in this embodiment, even if the lower end of the piping 110 extends further downward than the lower end of the support column 106, by using the conveying device 1, which will be described later, a small number of people can efficiently move the piping unit 100. can be installed on the target floor. The construction method will be explained in detail below.

FIG. 17 is a diagram showing an example in which the first application tool 130 and the second application tool 140 are attached to the piping unit 101. The first application tool 130 is attached to two locations on the front side and the rear side of the support portion 104 of the pedestal 102. Further, the second application tool 140 is attached to two locations on the upper surface of the base portion 103, one on the front side and the other on the rear side. The first application tool 130 and the second application tool 140 correspond to the support member 2 described in the first embodiment, and are members for supporting the piping unit 101, which is the installation target 9.

The first application tool 130 includes a connecting member 131 arranged horizontally between a pair of columns 106, 106 arranged in the left-right direction, and legs 132, 132 fixed to both ends of the connecting member 131. However, it can be attached to and detached from the front side and the rear side of the pedestal 102, respectively. Attachment fittings 133, 133 are provided on the upper surface side of both ends of the connecting member 131. The mounting fittings 133, 133 are attached to the mounting portions 122, 122 provided at predetermined height positions of the columns 106, 106 by fastening members made of bolts and nuts. The legs 132, 132 are arranged along the front or rear surface of the support column 106, and by attaching the mounting brackets 133, 133 to the attachment parts 122, 122 of the support columns 106, 106, the lower ends of the legs 132, 132 are It is installed at approximately the center height position of the support part 104. The first application tool 130 has a shaft portion 135 protruding outward at the center of the connecting member 131 arranged in the horizontal direction. For example, the shaft portion 135 is constituted by a bolt having a head, and the head of the bolt is provided at a predetermined distance from the surface of the connecting member 131, so that the shaft portion 135 is exposed between the head and the connecting member 131. It is formed by the shaft of the bolt. This shaft portion 135 corresponds to the rotating shaft 14 described in the first embodiment.

The second application tool 140 includes a connecting member 141 disposed above the base portion 103 in the left-right direction, and leg portions 142, 142 fixed to both ends of the connecting member 141. In this second application tool 140, the lower ends of the legs 142, 142 are attached to the attachment part 123 provided on the support wall 105 of the base part 103 by a fastening member consisting of a bolt and a nut. Such a second application tool 140 has a shaft portion 145 projecting outward at the center of a connecting member 141 arranged in the horizontal direction. For example, the shaft portion 145 is constituted by a bolt having a head, and the head of the bolt is provided at a predetermined distance from the surface of the connecting member 141 so that the shaft portion 145 is exposed between the head and the connecting member 141. It is formed by the shaft of the bolt.

When the piping unit 101 is installed on the installation target floor, the first installation tool 130 and the second installation tool 140 are attached as shown in FIG. 17 . However, as will be described later, during construction of the piping unit 101, the first installation tool 130 is used in an earlier step, and the second installation tool 140 is used in a later step. Therefore, only the first application tool 130 may be attached to the piping unit 101 to perform the first stage process, and the second application tool 140 may be attached to the piping unit 101 when moving to the next stage process.

Next, FIG. 18 is a diagram showing an example of the transport device 1 used during transport and construction of the piping unit 101. This transport device 1 is configured as a work trolley 150. The work trolley 150 can be arranged so as to sandwich the frame 102 of the piping unit 101, and includes a trolley body 151 with casters 155 attached to the lower surface, and a pair of trolley bodies 151 arranged opposite to each other on the upper surface side of the trolley body 151. lifting means 152, 152.

The trolley body 151 includes a pair of beams 153, 153 that are arranged to face each other at an interval wider than the longitudinal width of the pedestal 102 of the piping unit 101, and interconnects both ends of the pair of beams 153, 153. A pair of connecting beams 154, 154 are provided. Casters 155 are attached to the lower surfaces of both ends of the pair of beams 153, 153. The casters 155 are equipped with wheels that can rotate around a vertical axis, and support the work trolley 150 so as to be movable in any direction.

The connecting beams 154, 154 are attached so as to connect both ends of the pair of beams 153, 153 using a fastening member 156 made of, for example, a bolt and a nut. When the two connecting beams 154, 154 are attached to both ends of the pair of beams 153, 153, the truck main body 151 becomes a frame frame having a rectangular shape in plan view. Further, since the fastening member 156 is removable, at least one of the two connecting beams 154, 154 can be removed from the truck body 151. When one of the two connecting beams 154, 154 is removed from the truck body 151, the truck body 151 becomes a U-shaped frame frame in plan view.

The truck main body 151 includes lifting means 152, 152 which are erected at the center of the upper surface of a pair of beams 153, 153, respectively. The lifting means 152, 152 is, for example, a lifting drive unit constituted by a manual lift device as in the first embodiment. The lifting means 152, 152 has a column 157 having a predetermined height, and a lifting mechanism is mounted on the column 157 to support and raise/lower the pedestal 102. The lifting means 152, 152 are provided with an opening opening in the vertical direction on the front side of the support columns 157 arranged to face each other on the upper surface side of the truck body 151, and an opening opening in the vertical direction on the back side of the support columns 157. An operating handle 158 is provided. The operation handle 158 operates a winder 165 provided inside the support column 157. The end of a cable 164 such as a chain or wire rope is connected to the winder 165. Therefore, when the operation handle 158 is rotated in a predetermined direction about the rotation axis L1, the winder 165 rotates the internal winding drum together with the operation handle 158, and winds up or unwinds the cable 164. do. For example, the operating handle 158 is provided with a switchable one-way clutch, and has a structure that prevents the operating handle 158 from rotating in the opposite direction even if the operating handle 158 is released during a winding operation or a feeding operation. The cable 164 extending from the winder 165 is hung on a pulley 163 attached to the upper part of the inside of the column 157, and the cable 164 has its tip moved vertically along the opening on the front side of the column 157. A holding portion 161 is attached. The holding part 161 is a member that holds the pedestal 102. As shown in the enlarged view C of FIG. 18, the holding part 161 is made of a metal plate having a predetermined length in the horizontal direction, and has a locking part cut out in an upward U-shape in the longitudinal center of the metal plate. It has a section 162. This locking portion 162 pivotally supports each of the shaft portions 135 and 145 by receiving and locking each of the shaft portion 135 of the first application tool 130 and the shaft portion 145 of the second application tool 140.

Next, a procedure for installing the piping unit 101 on the floor to be installed using the work cart 150 as described above will be described. First, the piping unit 101 is assembled at a factory, and then the first installation tool 130 is attached to both the front and rear surfaces of the pedestal 102. Then, as shown in FIG. 129, casters 119 are attached to the side surfaces of the pedestal 102, and the pedestal 102 is laid down horizontally, and the casters 139 are grounded. The piping unit 101 is loaded onto a transport vehicle in the horizontal position shown in FIG. 19 and transported from the factory to the construction site. When arriving at the construction site, the piping unit 101 is unloaded from the transportation vehicle in a horizontal position, and is transported to the installation target floor using a temporary elevator at the construction site. In other words, the piping unit 101 of this embodiment can be transported to the installation target floor without using a crane at the construction site. Therefore, the piping unit 101 can be transported to the installation target floor with fewer people than when using a crane. Although FIG. 19 shows an example in which casters 139 are attached to the side surface of the pedestal 102, the present invention is not limited to this. For example, the frame 102 may be placed on its side and loaded on a truck other than the work truck 150, and then transported from the factory to the installation target floor.

When the piping unit 101 is carried to the installation target floor, a work cart 150 is prepared as shown in FIG. At this time, one connecting beam 154 of the work truck 150 is removed from the truck body 151. Then, the frame 102 is inserted between the pair of beams 153, 153, and the connecting beam 154 that has been removed from the truck body 151 is attached to the truck body 151. As a result, as shown in FIG. 20, the piping unit 101 is placed between the pair of lifting means 152, 152 (support portions 157, 157) provided on the working trolley 150. Thereafter, the operating handle 158 is rotated in a predetermined direction to align the holding part 161 of the lifting means 152, 152 to the height position of the shaft part 135 provided on the first application tool 130, and the locking part 162 of the holding part 161 is to lock the shaft portion 135.

Subsequently, the operating handles 158 of the lifting means 152, 152 are simultaneously rotated in a predetermined direction to wind up the cable 174. As a result, the holding portion 161 rises, and as shown in FIG. 21, the piping unit 101 is lifted by the lifting means 152, 152 of the working trolley 150.

After the piping unit 101 is lifted to a predetermined height, the piping unit 101 is then rotated in the R direction as shown in FIG. 22 to change the posture of the piping unit 101 from the horizontal position to the standing position. That is, since the U-shaped locking part 162 provided on the holding part 161 rotatably supports the shaft part 135 of the first application tool 130, the piping unit 101 can be rotated around the shaft part 135. By rotating, the piping unit 101 can be changed from a horizontal position to an upright position. When the casters 139 are attached to the side surface of the piping unit 101, the casters 139 can be easily removed from the piping unit 101 after the piping unit 101 is in the upright position.

Thereafter, the work trolley 150 moves the piping unit 101 to the installation location on the installation target floor as shown by arrow F2 in FIG. 23 while lifting the piping unit 101 in an upright position. As shown in FIG. 23, an opening 190 is formed in the floor slab 180 at the installation location of the piping unit 101 on the installation target floor. The work trolley 150 can transport the piping unit 101 to a position above the opening 190 formed in the floor slab 180.

Furthermore, when moving the work cart 150 with the piping unit 101 lifted, an auxiliary member 170 as shown in FIG. 24 may be attached to prevent the piping unit 101 from swinging around the shaft portion 135. You can also do it. The auxiliary member 170 shown in FIG. 24 is a metal fitting having a roughly U-shape, and is attached to both left and right side surfaces of the support portion 104 of the pedestal 102. The auxiliary member 170 includes a pedestal connection fitting 171 extending in the front-rear direction on the side surface of the pedestal 102, and leg portions 172, 172 extending downward at both ends of the pedestal connection fitting 171 in the front-rear direction. The frame connection fitting 171 is fixed to the lower end of the support portion 104 by a fastening member consisting of a bolt and a nut. The lower ends of the legs 172, 172 are fixed to the pair of beams 153, 153 by fastening members made of bolts and nuts. By attaching such auxiliary members 170 to both left and right side surfaces of the pedestal 102, the lower part of the piping unit 101 is fixed to the work trolley 150. Therefore, when the work trolley 150 moves while lifting the piping unit 101, the piping unit 101 can be prevented from swinging around the shaft portion 135, and the piping unit 101 can be moved safely. . This auxiliary member 170 is removed from the piping unit 101 and the pedestal 102 when the piping unit 101 moves to a position above the opening 190. Note that when moving the work trolley 150 while lifting the piping unit 101, it is optional whether or not to attach the auxiliary member 170 shown in FIG. 24.

As shown in FIG. 25, when the piping unit 101 is moved to a position above the opening 190 of the floor slab 180, the operating handles 158 of the lifting means 152, 152 provided on the work trolley 150 are rotated in a predetermined direction. The piping unit 101 is lowered. Accordingly, the pedestal 102 moves the support part 104 into the opening 190 while holding the plurality of pipes 110, and descends toward the lower floor. The legs 132, 132 of the first application tool 130 attached to the front and rear sides of the pedestal 102 protrude outward from the peripheral edge of the opening 190. Therefore, as the piping unit 101 is lowered toward the opening 190, as shown in FIG. The unit 101 stops descending. At this time, the piping unit 101 is held at a predetermined height position by the first application tool 130.

As shown in FIG. 26, when the piping unit 101 is supported by the first application tool 130, as shown in FIG. Install 140. However, the second application tool 140 may be attached to the base portion 103 in the previous steps. For example, the second application tool 140 may be attached to the base portion 103 in advance at a factory.

Then, in a state in which the piping unit 101 is supported by the first application tool 130, the holding part 161 of the lifting means 152, 152 is removed from the shaft part 135 of the first application tool 130, and the height position of the holding part 161 is moved to the second The shaft portion 145 is locked to the locking portion 162 of the holding portion 161 in alignment with the shaft portion 145 provided on the application tool 140 .

Thereafter, by rotating the operation handles 158 of the lifting means 152, 152 in a predetermined direction, the piping unit 101 is lifted up via the second tool 140. As a result, the legs 132, 132 of the first application tool 130 are in a floating state from the floor slab 180 around the opening 190. When the legs 132, 132 of the first application tool 130 are lifted off the floor slab 180, the first application tool 130 is removed from the piping unit 101, as shown in FIG. Thereby, the piping unit 101 becomes in a state where it can be further lowered relative to the opening 190.

After removing the first application tool 130, the operating handles 158 of the lifting means 152, 152 are rotated in a predetermined direction, and the piping unit 101 is lowered relative to the opening 190. Accordingly, the pedestal 102 moves the support part 104 deeply into the opening 190 while holding the plurality of pipes 110, and the lower part of the base part 103 fits into the opening 190. When the flange portion 121 provided on the base portion 103 comes into contact with the periphery of the opening 190, the descent of the piping unit 101 is stopped. That is, when the flange portion 121 comes into contact with the periphery of the opening 190 and the piping unit 101 cannot be lowered, it means that the piping unit 101 has been properly positioned. At this time, there is no need to perform delicate height adjustments of the piping unit 101.

Thereafter, the holding portion 161 is removed from the shaft portion 145 of the second application tool 140, and the work cart 150 is removed. Further, the second application tool 140 attached to the base portion 103 of the piping unit 101 is also removed from the piping unit 101. Then, by fixing the flange portion 121 to the floor slab 180 using anchor bolts or the like, the installation of the piping unit 101 is completed. By fixing the flange portion 121 to the floor slab 180 with anchor bolts or the like, the frame 102 of the piping unit 101 becomes an integrated structure with the building frame.

FIG. 29 is a diagram showing a state in which the piping unit 101 is installed on the floor slab 180 of the installation target floor. As described above, the piping unit 101 is installed by being lowered from the opening 190 formed in the floor slab 180 on the upper floor, so that the support part 104 is installed in a state protruding into the ceiling space on the lower floor. The support portion 104 has approximately the same length as the piping 110 supported by the pedestal 102 and holds the lower portion of the piping 110. Therefore, the piping 110 provided in the piping unit 101 is installed with its upper and lower parts fixed to the frame by the frame 102. Therefore, the pedestal 102 can suppress the vibration of the piping 110 when an earthquake occurs, and can prevent the fragile piping 110 from being damaged.

Further, when the piping unit 101 is installed as shown in FIG. 29, the base portion 103 is fitted into the opening 190 of the floor slab 180, and the opening 190 of the floor slab 180 is closed by the base portion 103. In addition, the inside of the base portion 103 is subjected to fire prevention treatment. Therefore, when the piping unit 101 is installed in the opening 190, it is possible to realize a fireproof division between the upper floor and the lower floor, and it is also possible to prevent a chimney formation phenomenon in the event of a fire. In other words, the piping unit 101 of this embodiment can realize a fireproof division by simply lowering and installing it with respect to the opening 190 of the floor slab 180 on the upper floor, and can also block the opening 190 and prevent the phenomenon of chimney formation. Therefore, it has excellent work efficiency.

In addition, the piping unit 101 has electrical cables 116 attached to each of the multiple piping 110 held by the frame 102, electrically connecting the indoor unit and the outdoor unit. Therefore, there is no need to perform a separate task of wiring the electrical cables 116 after installing the piping unit 101 in the opening 190 of the floor slab 180. Therefore, work efficiency can be improved by omitting the task of wiring the electrical cables 116 between the upper floor and the lower floor.

Figure 30 is a diagram showing the state in which the piping unit 101 is installed on the floor slab 180b of the lower floor and then installed on the floor slab 180a of the upper floor. For example, when the piping unit 101 is installed on the floor slab 180b of the lower floor, the upper end of the piping 110 held by the piping unit 101 is at a height h1 from the floor slab 180b. Here, the height h1 is, for example, about 500 to 1000 mm. However, depending on the floor on which the piping unit 101 is installed, the height h1 may exceed 1000 mm. On the other hand, the piping unit 101 installed on the floor slab 180a of the upper floor holds the piping 110 with a length shorter than the floor height H of the lower floor, and when installed on the floor slab 180a of the upper floor, a gap h2 is generated between the lower end of the piping 110 and the upper end of the piping 110 installed on the lower floor. This gap h2 is, for example, about 500 to 1000 mm. However, depending on the floor on which the piping unit 101 is installed, the gap h2 may exceed 1000 mm. After the piping unit 101 is installed on the floor slab 180a of the upper floor, a short pipe (refrigerant piping) corresponding to the length of the gap h2 is inserted into the gap h2, and the upper piping 110 and the lower piping 110 are connected to each other using a joint such as a mechanical joint. This allows the piping 110 held by the multiple piping units 101 installed on each floor to be interconnected.

Also, regarding the electric cable 116, the connector 117a of the electric cable 116 is held in the piping unit 101 installed on the floor slab 180b on the lower floor, and the connector 117a of the electric cable 116 is held on the piping unit 101 installed on the floor slab 180a on the upper floor. Connect the connector 117b of the electric cable 116 that is attached to the connector 117b. Thereby, the electric cables 116 held by the plurality of piping units 101 installed on each floor can be interconnected and electrically connected.

Further, the work trolley 150 used when installing the piping unit 101 is equipped with a pair of lifting means 152, 152 disposed to face each other on the upper surface side of the trolley main body 151, By moving the trolley body 151 with the means 152, 152 lifting the piping unit 101, it is possible to move the piping unit 101 to a position above the opening 190 formed in the floor slab 180 of the installation target floor. After the piping unit 101 is moved to a position above the opening 190, the pair of lifting means 152, 152 lowers the piping unit 101 inside the opening 190, thereby placing the flange portion 121 on the periphery of the opening 190. It is possible to install them in a state where they are in contact with each other. If such a work trolley 150 is used, it is possible to install the piping unit 101 by a small number of people without using a crane at the construction site, and there is an advantage that construction can be performed efficiently at low cost.

Therefore, the transport device 1 of this embodiment can be suitably used not only when transporting the piping unit 101 to the installation site, but also when installing the piping unit 101 to the installation target location. It has functions that allow work to be carried out efficiently at the installation site.

In addition, in the above, the case where the raising/lowering drive part provided as the lifting means 152,152 is a manual type was illustrated. However, the lifting means 152, 152 is not limited to a manual type, and an electric type may also be adopted.

Further, in the above, an example has been described in which the transport device 1 of this embodiment is not used when transporting the piping unit 101 from the factory to the construction site, but the invention is not limited to this. That is, the above-described transport device 1 may be used when transporting from a factory to a construction site, and the piping unit 201 may be transported while being loaded on the transport device 1.

(Third embodiment)
Next, a third embodiment of the present invention will be described. In this embodiment, as in the second embodiment, a piping unit 201 holding a plurality of pipes is illustrated as an installation target 9 installed inside a building under construction, and the piping unit 201 is transported to the installation site. The transport device 1 used for this purpose will be explained. Moreover, the conveyance device 1 of this embodiment can be used also when installing the piping unit 201 to the installation target location similarly to 2nd Embodiment. However, the construction method in this embodiment is different from that in the second embodiment. The third embodiment of the present invention will be described in detail below.

FIG. 31 is a perspective view showing a piping unit 201, which is the installation target 9 in this embodiment. This piping unit 201 is a unit in which a plurality of pipes (vertical pipes) arranged vertically across a plurality of floors of a building are aggregated, and a plurality of pipes can be installed on each floor. For example, the piping unit 201 can be installed one floor at a time from the lower floor to the upper floor in a newly constructed building.

This piping unit 201 includes a base 210 in which a plurality of frame members 211 are formed into a rectangular parallelepiped shape by welding or the like, and a pair of frames attached to the base 210 and extending above the base 210 in parallel to each other. rail parts 221 and 222, a first holding member 230 disposed inside the base 210, and a second holding member 240 disposed adjacent to the first holding member 230 inside the base 210. ing. The first holding member 230 and the second holding member 240 are members that hold a plurality of pipes 208 and 209 installed vertically inside the building. These pipes 208 and 209 are refrigerant pipes for air conditioning, and are used to circulate refrigerant between the outdoor unit installed on the roof of the building and the air conditioner (for example, indoor unit) installed on each floor. It's plumbing. The length of each of the pipes 208 and 209 held by the first holding member 230 and the second holding member 240 is, for example, the length obtained by dividing the length from the floor slab of the installation target floor to the floor slab of the upper floor into two. is formed as. The first holding member 230 and the second holding member 240 are capable of holding the plurality of pipes 208 and 209 in a state where they are arranged side by side in the left-right direction. Further, the first holding member 230 and the second holding member 240 hold electric cables 239 and 249 together with the pipes 208 and 209. These electric cables 239 and 249 are cables for transmitting and receiving electric signals between an outdoor unit installed on the roof of a building and an air conditioner (for example, an indoor unit) installed on each floor.

FIG. 32 is a diagram showing the base 210 and the pair of rail parts 221 and 222. The base 210 has a plurality of frame members 211 made of steel such as angle iron or channel steel assembled into a rectangular parallelepiped shape by welding or the like, and has an upper opening 212 and a lower opening 213. The depth dimension of the base 210 in the front-rear direction is smaller than the width dimension in the left-right direction, and is smaller than the depth dimension of a temporary elevator installed at a construction site, for example, so that it can be loaded onto the temporary elevator. The height of the base 210 may be, for example, approximately half the length of the pipes 208 and 209 held by the first holding member 230 and the second holding member 240.

Such a base 210 is installed in a state where it is fixed to the floor slab of the installation target floor. Since the base 210 has high rigidity, it has a steady rest function that suppresses the pipes 208 and 209 from vibrating greatly in the lateral direction, for example, in the event of an earthquake.

The pair of rail parts 221 and 222 are fixed to the base 210 by welding or the like on both rear left and right sides inside the base 210, and extend further upward from the upper opening 212 of the base 210. The height of the pair of rail portions 221 and 222 is, for example, approximately 1.5 to 3 times the height of the base 210, although it depends on the ceiling height of the floor on which it is installed. Therefore, a connecting member 225 that connects the pair of rail parts 221 and 222 to each other is installed at a predetermined height position above the base 210, and holds the pair of rail parts 221 and 222 in a parallel state. . Furthermore, a slit 223 extending in the vertical direction is formed on the front side of each rail portion 221, 222. The slit 223 is continuously formed from the lower end to the upper end of the rail parts 221, 222. Furthermore, ring-shaped engaging parts 224, 224 are provided at the upper ends of the pair of rail parts 221, 222.

Guide portions 215 are provided on both left and right side surfaces of the base 210, which are arranged in the horizontal direction (front-back direction). For example, the guide portion 215 is made of a metal plate in which a long guide hole 215a is formed in the horizontal direction (back and forth direction) at a central height position. Such guide portions 215 are installed at two locations on both left and right sides of the base 210: a first height position and a second height position higher than the first height position. . Further, a ring-shaped engagement portion 216 is provided at the upper part of the guide portion 215 installed at the first height position. This ring-shaped engagement portion 216 corresponds to a support member provided for the transport device 1, which will be described later, to support and lift the piping unit 201.

A caster attachment portion 214 to which casters 219 (see FIG. 39), which will be described later, can be attached is provided on one of the left and right sides of the base 210. Note that FIG. 32 shows an example in which the caster attachment portion 214 is provided on the right side surface of the base 210.

Furthermore, support members 217 are attached to both the front and rear surfaces of the base 210, which extend horizontally.

Next, a procedure for constructing the piping unit 201 using the work cart 202 as described above will be explained. First, the piping unit 201 is assembled at a factory, and then the casters 219 are attached to the caster attachment portions 214 provided on the side surface of the base 210. Then, as shown in FIG. 39, the piping unit 201 is changed to a state in which the base 210 is laid down and the casters 219 are in contact with the ground. This piping unit 201 is loaded onto a truck in a horizontal position and transported to a construction site. When arriving at the construction site, the piping unit 201 is unloaded from the truck while lying on its side, and transported to the installation target floor using a temporary elevator at the construction site. In other words, the piping unit 201 of this embodiment can be transported to the installation target floor without using a crane at the construction site. Therefore, the piping unit 201 can be transported to the installation target floor with fewer people than when using a crane.

When the piping unit 201 is carried to the installation target floor, a work cart 202 is prepared as shown in FIG. 39. At this time, the second connecting beam 265 of the work truck 202 is removed from the truck body 260. Further, the lifting means 271 and 272 are installed on the upper surfaces of the pair of beams 261 and 262, as shown in FIG. Then, the work trolley 202 is moved in the direction shown by arrow F3, and the piping unit 201 is inserted inside the open end of the pair of beams 261, 262. As a result, the base 210 of the piping unit 201 is housed between the pair of beams 261 and 262.

FIG. 40(a) shows a state in which the base 210 of the piping unit 201 is accommodated between the pair of beams 261 and 262 of the work trolley 202. At this time, each of the lifting means 271 and 272 of the work trolley 202 is in a state opposite to the front and rear surfaces of the base 210, respectively. In this state, the second connecting beam 265 is attached to the truck body 260 to increase the rigidity of the working truck 202.

Subsequently, the hooks 275 of the lifting means 271 and 272 are engaged with the engaging portions 218 provided on both the front and rear surfaces of the base 210. That is, the hook 275 is engaged with the engaging part 218 (supporting member) provided on the base 210 with the piping unit 201 disposed between the pair of supporting columns 270, 270 facing each other. . Then, the operating handles 279 of the lifting means 271 and 272 are simultaneously rotated in a predetermined direction to wind up the cable 274. As a result, as shown in FIG. 40(b), the piping unit 201 is lifted by the lifting means 271, 272 of the work trolley 202. The work trolley 202 can transport the piping unit 201 to any location in this state.

Further, when the piping unit 201 is lifted to a predetermined height, the piping unit 201 can be rotated as shown in FIG. 41, and the piping unit 201 can change its posture from a sideways posture to a standing posture. The work trolley 202 can also transport the piping unit 201 to an arbitrary location with the piping unit 201 in an upright position.

After transporting the piping unit 201 to a predetermined location, the work trolley 202 rotates the operating handles 279 of the lifting means 271 and 272 in the opposite direction to the above while maintaining the upright posture of the piping unit 201. As a result, the cable 274 is let out and the piping unit 201 is lowered and temporarily placed on the floor. When the piping unit 201 is temporarily placed on the floor, the casters 219 attached to the side surface of the base 210 are removed. Further, the lifting means 271 and 272 are removed from the pair of beams 261 and 262 and installed on the upper surfaces of the first connecting beam 264 and the second connecting beam 265. Then, the hooks 275 of the lifting means 271 and 272 are engaged with the engaging portions 216 provided on both left and right side surfaces of the base 210. At this time, if the casters 219 are removed first, the casters 219 will not get in the way when the hook 275 is engaged with the engaging portion 216, improving work efficiency.

Thereafter, the operating handles 279 of the lifting means 271 and 272 are simultaneously rotated in a predetermined direction to wind up the cable 274 again. As a result, as shown in FIG. 42, the piping unit 201 is lifted up again by the lifting means 271, 272 of the working trolley 202.

When the lifting means 271, 272 lifts the piping unit 201, it lifts it until the bottom of the base 210 is at a higher position than the center part 262a of the arched beam 262. As a result, when moving the work cart 202 in the direction of arrow F4, the beam 262 and the base 210 do not interfere with the pipe 293 protruding upward from the opening 291. That is, the arched beam 262 and the base 210 move above the pipe 293 in the direction of arrow F4. The piping unit 201 can then be moved to a position above the opening 291.

When the piping unit 201 is moved to a position above the opening 291, the operation handles 279 of the lifting means 271, 272 are operated to lower the piping unit 201 to the installation location 290. Then, the bottom peripheral edge of the base 210 is fixed to the anchor 292. Thereby, the base 210 is installed so as to surround the opening 291. Further, by fixing the base 210 to the floor slab by the anchors 292, the base 210 becomes an integral structure with the frame (floor slab).
