Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION The present invention relates to a construction site,
The present invention relates to a transfer device used for unloading secondary members, finishing materials, equipment pipes, and other materials from a state where they are loaded on a temporary lift, horizontally transporting them, and unloading them to a destination point.

[0002]

2. Description of the Related Art At a construction site, materials are hoisted to a working floor by a temporary lift, and for the work of picking up, carrying, and unloading from this lift, various methods have been conventionally used. However, there are the following three typical ones.

The first is a method of carrying out the work of picking up, carrying and unloading using a hand lift, and the second is a method of carrying out the work of picking up and unloading manually, and carrying out the carrying work using a trolley with casters. No. 3 is a method in which carts with casters are prepared for the number of times of transportation, materials are loaded on the carts from the time of loading the lift, and the carts are transported and stocked as they are. In addition to this, there is an example in which a pallet is used instead of a trolley with casters, but the basic work procedure is the same.

[0004]

In the method using the handlift, the ability of the handlift to support the forks is limited, and the weight of the material that can be conveyed at one time is small, resulting in poor work efficiency. Also, depending on the shape of the material such as equipment piping material, it cannot be handled as it is, and it is necessary to separately prepare pallets, packing materials and the like.

On the other hand, when the cart with casters is used, the work of unloading from the lift and the work of unloading at the work point must be done manually, and especially for large-sized materials. A large number of workers must be spent.

Further, in the method of preparing the carts with casters for the number of times of transportation, there is a problem that the number of carts required becomes enormous. Furthermore, in any of the above-mentioned methods, there is a large proportion of human power.

The object of the present invention is to solve the above-mentioned disadvantages of the prior art, and to freely load a wide range of loading weights regardless of the packing style of materials, and to carry out a series of operations for unloading, transporting, and unloading materials from a material lift. An object of the present invention is to provide a material transfer device for a construction site that can automatically perform the work without depending on human power.

[0008]

In order to achieve the above-mentioned object, the present invention comprises a driving unit having a battery and an air compressor built in the body cover, and a flat loading unit horizontally protruding from the driving unit. The gist of the present invention is that the loading section ejects compressed air from the air compressor on the lower surface to levitate by air pressure, and the drive section is further provided with a motor and a propulsion mechanism such as wheels driven by this motor. It is a thing.

[0009]

According to the first aspect of the present invention, since the loading section is pneumatically floated on the floor surface to float, the transportable weight can be set large by adjusting the area of the loading section.
In addition, since the loading section is flat, materials can be transported regardless of the packing style. Then, the material can be unloaded and unloaded without any manual work by inserting or withdrawing the flat plate-shaped loading section below by simply preparing a square piece or the like underneath.

According to the second aspect of the present invention, in addition to the above-described action, the propulsion mechanism such as the wheels can facilitate the transportation.

[0011]

Embodiments of the present invention will now be described in detail with reference to the drawings. FIG. 1 is a side view showing an embodiment of a material conveying apparatus for a construction site according to the present invention, FIG. 2 is a plan view of the same, and FIG. 3 is an exploded perspective view.

The material conveying apparatus of the present invention comprises a drive unit 1,
The loading unit 2 projects from the drive unit 1. Of these, the drive unit 1 has a battery 4 and an air compressor 5 mounted inside a vehicle body portion covered by a body cover 3.

Further, the drive unit 1 is provided with a motor (not shown) and a propulsion mechanism such as wheels 6 driven by the motor. The battery 4 serves as a power source for the drive motor of the air compressor 5 and the drive motor of the wheels 6 and the like.

On the other hand, the loading unit 2 is a flat plate-like member that projects horizontally rearward as an extension of a sled-shaped chassis of the vehicle body of the drive unit 1.

A large number of air holes 7 are provided on the lower surface of the loading section 2, and the air compressor 5 and the air holes 7 are communicated with each other through an air guide path (shown in the drawing) through which the air holes 7 communicate. The air holes 7 are provided not only on the lower surface of the stacking unit 2 but also on the lower surface of the driving unit 1, that is, the lower surface of the entire conveying device.

Further, since the air compressor 5 and the motor of the drive unit 1 are wirelessly controlled by the remote control device 9, the drive unit 1 is provided with the receiver 8 and is connected thereto.

In this way, the compressed air from the air compressor 5 is jetted from the air holes 7 so that the entire unit including the loading section 2 can be levitated by the air pressure. In addition to the above-mentioned embodiment, the levitation mechanism inflates an air bag as in JP-A-4-164708, and causes the air blown from the air bag to float between the air bag and the running floor surface. It may be one.

The propulsion mechanism provided in the drive unit 1 may be a jet injection mechanism other than the wheels 6.

Next, usage and operation will be described. 4 to 6 are side views showing a use state, and 10 is a material 11
Is a lift that lifts.

In order to place the material 11 on the lift 10, a space is secured on the lower surface by a height adjusting material such as a square member 12.

On the other hand, in the material conveying apparatus of the present invention, air pressure does not act on the lower surface of the loading section 2 and the loading section 2 is also at a low position, so that it is inserted into the space below the material 11. The wheels 6 are operated so that

Next, the air compressor 5 is started, and compressed air is ejected from the air holes 7 to float the whole including the loading section 2 by the air pressure to the floor.

With this, the unloading work is completed, the work is conveyed by the wheels 6 as it is, and when the necessary position is reached, the air pressure is turned off to complete the unloading work.

[0024]

Industrial Applicability As described above, the material transporting apparatus in the construction site according to the present invention can freely load a wide range of loading weights regardless of the packing style of the material, and can unload and transport the material from the material lift. Since a series of unloading operations can be performed automatically without depending on human power, labor saving at the construction site,
This contributes to robotization.
