Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Field of Application) The present invention relates to a method for constructing heavy objects and an auxiliary device for the construction.

[Conventional technology]

For example, a large number of concrete blocks are buried in sidewalks, plazas, etc., and they are transported in bulk in trunks and laid one after another.

[Problem to be solved by the invention]

Up until now, the concrete blocks have been transferred from the trunk to a transport vehicle such as a forklift I- and transported to the vicinity of the construction site, but after that, the concrete blocks on the transport vehicle were transported to the actual construction site. were carried out one by one by hand. This work is not only hard labor but also inefficient, and as a result, it is not only dangerous to drop the blocks during the work, but also causes the blocks to break.

In view of the above circumstances, an object of the present invention is to enable work to be carried out efficiently and safely, and to prevent heavy objects from falling and breaking.

[Means to solve the problem]

In order to solve the above problem, the heavy object construction method according to the invention according to claim 1 first transfers the heavy object, which is construction materials transported by vehicle, to a transport vehicle, and then transfers the transferred heavy object, By holding a balance device having a holder while maintaining weight balance with the same weight object, the object can be manually transferred from the transport vehicle to the construction site.

The construction auxiliary device according to the invention according to claim 2 is a construction auxiliary device attached to a transportation vehicle having a structure for transferring heavy objects such as construction materials transported by the vehicle,
A suction tool capable of adsorbing the heavy object to be transferred using vacuum suction force, a movement mechanism that enables the suction tool to move three-dimensionally, and a heavy object attached to the mechanism to be adsorbed by the suction tool. It has a balance mechanism that works to always maintain balance.

[Operation] Heavy objects such as construction materials transported by vehicle are first transferred to a transport vehicle, and the transferred M ornament is placed between it and an object of the same electric weight on a balance device having a holding device such as a suction tool. If you hold it while maintaining the weight balance, it will be easier and faster to transfer heavy objects to the construction site without having to manually move them, and you will avoid accidentally dropping them.

In this case, if a construction auxiliary device having a suction tool, a moving mechanism, and a balance mechanism is provided on the transport vehicle, the construction method described in item 1 can be easily realized.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described in detail below with reference to embodiments thereof and the drawings.

FIG. 1 and FIG. 2 show an embodiment of the heavy object construction method and the construction auxiliary device according to the present invention. In this embodiment, concrete blocks (construction materials) 1 are heavy objects, and these are transported to the construction site 4 using a forklift 1 (general vehicle) 2 and a construction auxiliary device 3 attached thereto. The equipment that was relocated to the site is now being repaired. As you can see in these figures,
The forklift 2 is equipped with a mast 6 at the front, and the mast 6 can be tilted back and forth by a tilt I cylinder 7. A front plate 8 is attached to the front side of the mast 6 so that it can move up and down together with the inner mast.
A finger par 9 is provided on the front side. Two forks 10.10 are attached to the finger par 9 on the left and right sides. A stopper 11 protrudes from each fork 10 to ensure that the valent 12 is always in a fixed position. On top of the valent 12, concrete professional software, which is transported along with rank 1 to rank (transport vehicle) not shown, is placed. The front plate 8
A graquent 15 is attached to the bracket 15, and a fixed seat 16 equipped with a rotation drive section is provided on the bracket 15. A pair of left and right side plates 17, 17 are provided above the fixed seat 16 so as to be rotatable within the range shown in FIG. Same plate 1.
7.17 is provided with elongated holes 20.2J that are oriented in the horizontal and vertical directions to allow the driving wheels 18.19 to move. As a result, the link mechanism 22, which together with the rotary drive section constitutes a moving mechanism, is attached so as to be able to move up and down. This link mechanism 22 includes a main elevating link 23 whose base side is rotatably supported between both side plates 17 and 17, and an auxiliary elevating link 24 located above and parallel to the link 23. , a force 1 sinker weight (part of the balance mechanism) 25 is attached to the rear end of the main elevating link 23.
I'm being kicked. The main elevating link 23 has a lancing cylinder (main part of the balance mechanism) 30 attached to the side plate 17.
They are connected in such a way that they can be maintained in a so-called weightless state by providing a lifting force corresponding to their weight. A hanging link 26 extending downward is rotatably attached to the tips of both the lifting links 23, 24. Thereby, the suspension link 26 can rotate back and forth around the tip of the main elevating link 23.

A take-up board 27 is suspended from the lower end of this suspension link 26 so as to be horizontal, and a suction tool (holder) 28 is provided below the inter-mounting board 27. .

The suction tool 28 includes a main body 28a and a suction pad 28b provided at the bottom of the main body 28a.
The suction pad 28b can be attracted to the rough surface of the concrete block 1 by the vacuum suction force acting through the inside acting on the through hole of the suction pad 28b. An operation box 29 is attached to the front part of the mounting board 27 so that the vacuum suction force can be turned on and off manually by a worker at the work site 4.

Concrete blocks transported in trunks...
The stacked units are sequentially carried out by the forklift l-2 by inserting the fork 10 into the pallet 12. The concrete pieces carried near the construction site 4 by the forklift 2 are transferred to the construction site 4 by the construction auxiliary device 3 in order from the top. That is, the suction tool 28 is manually moved so that it is above the concrete blocks placed on the pallet 12, and the buttons on the operation box 29 are operated to generate a vacuum suction force on the suction tool 28. Then, the suction tool 28 is made to adsorb to the secondmost part of the concrete block. When the load button of the operation button 29 is pressed and the concrete slab 11 floats, release the button. This creates a load-balanced state, that is, a zero-gravity state when loaded, and the subsequent equipment and concrete blocks can move easily in three dimensions with little force applied, depending on the sense of the worker's hands. It becomes like this. Lowering the concrete blocks to the destination can be similarly done with light force, and after lowering, the vacuum suction force is released and the no-load button on the operation box 29 is operated to bring the no-load balance state. This completes the relocation of the concrete blocks to the construction location 4. Subsequent relocation is also easy if the same operation is performed as described above. The next loading unit is operated in the same manner by the forklift 2.

As mentioned above, the heavy object construction method according to the present invention includes:
Heavy objects such as construction materials transported by vehicle are first transferred to a transport vehicle, and the weight balance is maintained between the transferred heavy objects and the same heavy objects on a balance device having a holding device such as a suction tool. Since the device is held while holding the object, it becomes easier and faster to manually transfer heavy objects to the construction site, and there is no chance of them being accidentally dropped.

In this case, if the construction auxiliary device having a suction tool, a moving mechanism, and a balance mechanism is provided on a transport vehicle, the construction method described above can be easily realized. [Effects of the Invention] Heavy object construction method according to the present invention Since the structure and its construction auxiliary equipment are configured as described above, construction work involving heavy objects can be carried out easily and efficiently, and the danger and loss of dropping heavy objects can be avoided. become able to do.
