BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a heavy-lifting apparatus used when hanging a heavy object such as an air conditioner on a vertical surface such as a wall surface in a latching manner.

[0002]

2. Description of the Related Art Recently, in order to save space, the number of cases where an outdoor unit of an air conditioner is hung on a high position on a wall has been increasing. This operation is usually performed as follows.

[0003] First, a base of an outdoor unit is mounted on a wall surface.
Next, the outdoor unit is lifted, mounted on the mount, and fixed.
A wall mount type is used as a mount. In some cases, while a part of the gantry is attached to a wall surface, another part of the gantry is attached to an outdoor unit, and the gantry is connected with the outdoor unit raised. When the installation position is high, a ladder or a simple type of elevator is used.

[0004]

However, since the wall surface is a vertical surface, the operation of installing the outdoor unit on the wall surface is inherently more complicated than the operation of installing the outdoor unit on the ground or the floor. In addition, the outdoor unit is light dozens of kilometers
g, and heavy ones exceed 100 kg. For these reasons, the installation work on the wall surface is not easy. In the case of manual work, about four workers are required.

[0005] The use of an elevator can reduce the burden on the operator, but since the elevator is self-supporting, it can be a simple type, but it is large, heavy, and difficult to transport.

The present invention has been made in view of the above circumstances, and an object of the present invention is to facilitate installation work when installing a heavy object such as an air conditioner on a vertical surface such as a wall surface in a hook-like manner, and to reduce the size. An object of the present invention is to provide a heavy-weight lifting device that is lightweight and easy to carry.

[0007]

In order to achieve the above object, a heavy object lifting apparatus according to the present invention comprises a base member detachably fixed to a vertical installation surface on which a heavy object is installed, and a base member to be installed. A heavy load holding member coupled to a heavy load and suspended and supported by a flexible strip hanging from the base member; and extending downward from the base member and lifting the heavy load holding member by winding the strip. An operating member having a winch at the bottom.

[0008] In the heavy lifting apparatus according to the present invention, first, a gantry for fixing the heavy object to the installation surface is attached to the installation surface. In addition, the base member is attached to the installation surface at a position above the gantry. Next, the heavy object holding member hanging from the base member and the heavy object are joined. Then, by operating the winch attached to the lower portion of the operation member extending downward from the base member, the heavy object holding member is lifted and placed on the gantry.
Finally, the base member is removed from the mounting surface.

As described above, in the case of the present invention, a heavy object is lifted by a hanging-type device having no support.

The base member has a vertical member having an upper end screwed to the mounting surface of the heavy object and an end on the mounting surface side of the base member connected to the lower end, and an upper end connected to the upper end of the vertical member. It is preferable that the lower end is fixed to the installation surface by a diagonal member connected to the end of the base member on the side opposite to the installation surface.

Here, the base member 11 includes an auxiliary member 18,
Attach to wall 40 using 19. Auxiliary member 1
Reference numeral 8 denotes a vertical member whose upper end is suspended and fixed to a wall surface by a screw 17. A rear end of the base member 11 is screwed to the lower end thereof, and a pair of right and left overhanging portions 18 is provided.
a, 18a are provided. On the other hand, the auxiliary member 19
The upper end is a diagonal member screwed to the upper end of the auxiliary member 18 and the lower end is screwed to the front end of the base member 11.

The strip member 12 is provided with a pin 11 in the base member 11.
a, it returns downward to the base member 11 via a pulley 13a provided in the central portion of the heavy object holding member 13, and returns to the base member 11 via two pulleys 11b and 11c in the base member 11. It is out to the front side. And
It hangs down along the operation member 14 and is connected to the winch 15. As a result, the heavy object holding member 13 is suspended below the base member 11, and moves up and down by operating the winch 15. The outdoor unit 20 is fixed below the heavy load holding member 13 by binding with the band 16.

The upper end of the operating member 14 is connected to the front end of the base member 11 by a screw, and is fixed at an arbitrary inclination angle by operating the screw. Operation member 14
Has a double cylinder structure that can be extended and contracted in the longitudinal direction, and the height of the winch 15 is adjusted by this expansion and contraction. Winch 15
Is manually operated here, but it is needless to say that it may be electrically operated.

Next, a method of installing the outdoor unit 20 according to the first embodiment of the present invention will be described.

The gantry 30 is mounted on a wall surface 40 as an installation surface. Also, using the auxiliary members 18 and 19,
The base member 11 is attached to the wall surface 40 above 0.
If the auxiliary members 18 and 19 are used, the base member 11 can be attached with one screw 17.

On the other hand, on the ground, the heavy object holding member 13 is bound and fixed to the upper surface of the outdoor unit 20 by the band 16. In this state, the winch 15 is operated in the direction in which the heavy object holding member 13 rises. As a result, the outdoor unit 20 is pulled up above the mounting bases 33, 33 of the gantry 30, and is mounted thereon.

In this embodiment, when the outdoor unit 20 is pulled up, the entire gantry 30 is attached to the wall surface 40 in advance. For example, the horizontal member 31 and the vertical members 32, 32 of the gantry 30 are attached to the wall surface 40. Mounting, mounting base 3
3 and 33 are attached to the outdoor unit 20 and the outdoor unit 20 is pulled up. In this state, the mounting bases 33 and 33 are attached.
Can be connected to the vertical members 32, 32.

As described above, in the first embodiment of the present invention, the outdoor unit 20 is directly lifted to the installation position by using one heavy object lifting device 10, and the installation is easily performed. 100 kg
In the case of a large-sized outdoor unit 20 exceeding the above, the installation is performed by two workers without requiring much labor.

Further, since the heavy object lifting device 10 is not a self-standing type but a suspension type, it does not require a column or a supporting member thereof. Therefore, it is very small, lightweight and easy to carry. If the auxiliary members 18 and 19 are used, sufficient fixing strength can be obtained, the base member 11 can be attached with one screw 17, and the load applied to the wall surface 40 at right angles is a pair of right and left. Since the projections are dispersed by the overhang portions 18a, 18a, there is an advantage that damage to the wall surface 40 can be minimized.

FIG. 4 is a front view of a heavy-lifting apparatus according to a second embodiment of the present invention.

In the second embodiment of the present invention, the outdoor unit 20 of the air conditioner is installed on a vertical wall 40 by using a pair of left and right heavy lifting apparatuses 10, 10. When the outdoor unit 20 is heavy, for example, a pair of left and right heavy lifting apparatuses 10 and 10 can be used as in the present embodiment. When a downward surface such as an eaves surface exists near the installation position, the base member 11 can be attached to the downward surface.

In the above-described embodiment, the flexible strip 12 is formed by two pulleys using a pulley for a heavy load, but may be formed by one pulley. The heavy object holding member 13 may be a hook or the like.

[0027]

As described above, the heavy-lifting apparatus according to the present invention is of a hanging type in which the base member is mounted on the heavy-loading installation surface as well as the lifting of the heavy load to facilitate the installation work. Therefore, there is no need for a column for supporting itself and its supporting member. Therefore, it is small and lightweight, and transport and the like are very easy. In addition, since the suspension type does not interfere with the eaves and the like, the heavy object can be directly lifted to the installation position, which also facilitates the installation work.

A vertical member whose upper end is screwed to the installation surface of the heavy object and whose lower end is connected to the installation surface side end of the base member, and a vertical member whose upper end is connected to the upper end of the vertical member and whose base is connected to the lower end. When the base member is fixed to the installation surface using a diagonal member to which the end of the member on the side opposite to the installation surface is connected, there is an effect of minimizing damage to the installation surface and protecting the surface.
