In FIG. 1, a lifting arm 40 extending substantially horizontally from the upper portion of the rod 11 is provided on the upper portion of the rod 11 at an upper position corresponding to between the left and right legs 20 and 30 opened. Have been. An arm bending means 41 is provided on the cylinder 10 side of the arm 40. The arm bending means 41 causes the arm 40 to bend substantially in parallel with the cylinder 10 and fall (FIG. 2). .

The arm bending means 41 comprises a bending center shaft 44 and, as shown in FIG. 1, a lock pin 43 for maintaining the arm 40 in a usable and extended state. The above-mentioned bending center axis 44 is a non-bending side member 441 that overlaps in the extended and bent states.
And a bending side member 444 are provided as shafts penetrating between both members. Each of the non-bending side members 441 is integrated with the upper part of the cylinder 10. Note that the bending-side member 444 is an arm body described later.

The lock pin 43 is connected to the arm 40
A non-bending side member 441 overlapping in the extended state of
It is inserted removably into a lock hole 430 (FIG. 2) formed through the space between the two members with the bending side member 444. Therefore, when bending the arm 40, the lock pin 43 is pulled out, and then the distal end side of the arm body 444, which is a bending-side member, is pushed down to be bent.

In this embodiment, the arm body 444 further includes an extension arm 401 that can extend in the direction in which the arm body 444 extends, that is, in the distal end side. This extension arm 401

In the example shown in the figure, the extension arm 401 formed in a rectangular tube shape, which is slightly smaller, is inserted into the arm body 444 formed in a rectangular tube shape so as to be slidable in the longitudinal direction. The present invention is not limited to this, and may have an appropriate configuration.

Referring to FIGS. 3 and 4, the lifting and transporting (peeling) of the compressor 100 having a weight of about 60 kg will be described. First, the present apparatus is brought close to the target object, that is, the compressor 100. In this case, as shown in FIG.
You may roll using only. The movement in the compacted state occupies the minimum space of the present apparatus, so that the present apparatus itself can be easily transported or moved in a narrow corridor or elevator.

Of course, if there is no problem, the legs 20 and 30 may be moved while being appropriately extended as shown in the figure.
For example, when transporting a newly installed compressor (not shown) to the installation position. In the extended state, the apparatus can stably move. Of course, in the case of extension, the lock pins 23 and 33 are inserted into the lock holes in order to fix the state. In any case, the present device may be moved by pressing the gripping portion 19 provided in an appropriate shape on the side surface of the cylinder 10.

For example, the 0 and 30 may be equipped with a simple locking tool (not shown) that can be easily engaged and disengaged on the side surface of the cylinder 10, for example.

When the present apparatus is moved in a compacted state in the vicinity of the compressor 100 as an object,
First, the left and right leg portions 20 and 30 are appropriately extended by pulling down the left and right leg portion main bodies 222 and 333, and the lock pins 23 and 33 for fixing the state are inserted into the lock holes. And if necessary, in this example, the leg body 2
The extension legs 201 and 301 are pulled out from the 22, 22 and 333 as appropriate. The extended leg portions 201 and 301 that are drawn out may be configured to fix the extended state by appropriate means (not shown). In this example, since the drawer is of the slide type, it is configured to be incapable of sliding simply by receiving the load of the target object, for example, a simple structure such as Kunaru that slides under load. Thus, leg 2
The device is stabilized by extending 0,30. The use of wheels having a stopper function for each of the wheels 101, 202, and 302 can further stabilize the apparatus.

Next, the arm body 444 of the arm 40 is raised in a substantially horizontal direction, and the lock pin 4 is inserted into the lock hole 43.
4 is inserted to fix and maintain a substantially horizontal state. In this case, the arm 40 is rotatable around the axis of the rod 11, but can be stabilized by extending the arm 40 between the left and right legs 20, 30. And if necessary, in this example, the arm body 4
The extension arm 401 is pulled out from 44 so as to extend above the object (100). The extended arm 401 pulled out may be configured to fix the extended state by appropriate means (not shown). In this example, since the drawer is of the slide type, it has a simple configuration in which the slide cannot be made only by receiving the load of the object (100).
Thus, the preparation for lifting the apparatus is completed.
At an appropriate stage during this time, the foot 11 is previously depressed to extend the lot 11 upward. Object (100)
Adjust so that it is located above

Next, by depressing the foot pedal 12, the lot 11 is brought close to the target object (100) on the drawing, and the desired object (100) is operated while operating the foot pedal 12 via a required suspending member 402. Is lifted, and is transported (moved) to a required position as it is in the lifted state. Of course, if a similar operation procedure is applied in a reverse manner as appropriate, a heavy-weight installation operation can be performed.

According to this embodiment, when handling relatively heavy equipment and devices installed in a building, removal and installation can be performed only by lifting the heavy object and pushing by hand while being lifted. It is possible to provide an inexpensive hoisting and transporting device that is simple in structure. Therefore, even if a relatively heavy compressor or the like is to be replaced in repairing and maintaining / inspecting the equipment for cooling and heating equipment of a building, manpower is not required. Can be reduced, and work costs can be reduced.

According to each of the first to fourth aspects of the present invention, a heavy object such as equipment or devices installed in a building can be easily lifted or lowered. Therefore, removal and installation work can be performed quickly, and a simple and inexpensive lifting and carrying apparatus can be provided. Further, since no human power is required for repairing and maintenance work of the cooling and heating equipment in the building, workability can be improved, the number of workers can be reduced, and work costs can be reduced. Can be.

According to each of the first and second aspects of the present invention,
In any case, since the present apparatus can be made compact, storage and transportation of the apparatus, and movement within the building can be performed smoothly.

According to the third and fourth aspects of the present invention,
In any case, since the arms and legs can be extended, relatively heavy objects can be stably handled in spite of the compact device.
