Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a carrying device suitable for carrying a switchboard or the like.

[0002]

2. Description of the Related Art Conventionally, the work of carrying a switchboard is roughly classified into the following three. (1) Insert a roller or roller conveyor under the switchboard and push the switchboard to move it horizontally. Then, the insertion or removal of the roller or the like is performed by lifting the switchboard using a lever or a jack. This method has the advantages that the equipment and tools are the cheapest and easy to obtain, and the storage of tools does not require special management.

(2) A switchboard is placed on an integrated trolley or a hand pallet truck, and the switchboard is horizontally moved by the integrated trolley or the like. Then, the work of placing the switchboard on the dolly or the like and lowering it from the dolly or the like is performed by using a separate lifting tool, a crane car, or a unic car. This method is superior in maneuverability to the method (1) and relatively easy to work.

(3) It is carried out by using a special gate-type carrier cart equipped with a suspension device. This method has the advantage of the highest safety in transportation because the switchboard is hung from above and moved.

[0005]

However, in the transportation method of (1) above, it is necessary to move a tool such as a roller along with the movement of the switchboard, which is time-consuming and not easy to change the direction. There is a high risk of the switchboard falling over when changing tools. In the method (1), the floor surface is easily damaged during transportation, and thus floor curing is required.

Further, the method (2) uses a dolly or the like, so that the tool cost is slightly higher than that of the method (1), and the size of a transportable switchboard is considerably restricted.
Since most of the hand pallet trucks have three-point support, the stable center of gravity support position moves when the switchboard is moved up and down, and there is a danger of tipping over.

Further, in the method (3), since the switchboard is hoisted, the device itself tends to be large and heavy, and a considerable space is required in the transportation route. Further, transportation, transportation, and storage of the device itself require a great deal of cost, and the manufacturing cost is extremely high because of the special manufacturing.

The present invention has been made to solve the above-mentioned drawbacks of the prior art, and an object of the present invention is to provide a carrying device capable of safely carrying a heavy load by a small number of people. It is another object of the present invention to provide a carrying device that can easily carry objects of various sizes and types. A further object of the present invention is to provide a carrying device that does not require a special device for loading and unloading the carried object. And the present invention relates to transportation,
The purpose is to provide a transportation device that does not cost much to store.

[0009]

In order to achieve the above-mentioned object, a carrying device according to the present invention is coupled and separable at an arbitrary interval and holds both side edges of an object to be carried. It is configured to have support members to be lifted, carriages arranged at both ends of these support members, and an elevator for raising and lowering the support members from these carriages as starting points.

The support member may be angle steel, plate-shaped or rod-shaped, but it is preferable to use angle steel so as to easily and surely hold an object to be transported. In addition, it is desirable to provide casters on each trolley so that the trolley can travel in any direction. As the elevator, a manual hydraulic jack may be used in order to facilitate the work, handle the device, and simplify the device. An elevating member may be interposed between the support member and the elevator so that the elevator moves up and down to bring the support member into contact with the floor surface and to separate the carriage from the floor surface via the elevator.

[0011]

According to the present invention constructed as described above, the supporting member holds both side edges of the object to be conveyed, the object to be conveyed is lifted by the elevator through the supporting member, and then the object to be conveyed is pushed to move the supporting member. The carts placed at both ends move,
The transported object can be easily transported in any direction.
Therefore, when a switchboard or the like is transported, a small number of people can easily transport and install the switchboard without the risk of the switchboard falling over. Moreover, since the support members holding the both sides of the transported object can be coupled at an arbitrary interval and can be separated, it is possible to easily cope with transportation of the transported objects of various sizes and types. Since the support member is lifted and lowered by the elevator while holding the transported object, no special device for loading and unloading the transported object is required, and the supporting members are arranged on both sides of the transported object. Since the support member is separable, it can be easily transported and stored and its cost can be reduced.

When the elevating member is interposed between the supporting member and the elevator and the supporting member is in contact with the floor surface,
If the dolly can be separated from the floor,
When one side of a heavy load is lifted, the load is tilted, a support member is placed below the lifted side, and the edge of the load is placed on the support member. Not only can the transported object be tilted easily even when it is on the table, but since the carriage is not in contact with the floor surface, the support member does not move when the transported object is tilted. Can be prevented.
