Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a tilt type turntable which is advantageous for changing the direction of a lifted load when lifting the load along an inclined surface.

[0002]

2. Description of the Related Art It is advantageous to use a turntable when changing the transfer direction of luggage. Such a turntable is constructed by rotatably mounting a table on a base plate installed on a predetermined installation surface such as a floor surface or the ground, so that the luggage mounting surface on the table can maintain a horizontal state. It is generally configured in.

On the other hand, at a construction site, floor materials, wall materials or auxiliary materials on the upper floors are sometimes lifted or pulled up from stairs. When carrying out such cargo-handling work, recently, a dolly for lifting a load along the stairs is used, but this dolly has a problem that it cannot change the direction of the lifted load.

[0004]

It is possible to use the horizontal turntable as described above in order to change the direction of the lifted load. However, in this turntable, since the loading surface of the luggage is horizontal, the luggage with the inclined surface is once placed on the loading surface, and then the direction is changed, which makes the work rather troublesome. There is a problem, and most of them are not used at present.

In particular, it is indispensable to change the direction of the luggage on the stairs bent at 90 degrees or 180 degrees such as when a landing is provided on the way. When carrying out cargo handling work in such a place, it is necessary to lower the cargo once on the floor and lift it again or to perform a high degree of balance work in order to make the cargo horizontal and change the direction at the landing, which requires considerable heavy labor. And the risk of damage to your luggage during this process and by leveling your luggage the width of the landing,
There are problems such as the need to increase the depth.

An object of the present invention is to provide an inclined type turntable which can easily change the direction of a load accompanying a cargo handling work on an inclined surface.

[0007]

In order to solve the above-mentioned problems, an inclined turntable according to the present invention comprises a table having an upper part provided with a mounting part inclined at a predetermined angle and a lower part provided with a rotating body. And a pedestal on which the table is movably placed and a restriction member for restricting the moving direction of the table in the rotation direction is provided.

In the tilt type turntable, it is preferable that the regulating member is a shaft fitted at a predetermined position of the table, and it is preferable to provide an angle adjusting means for adjusting the tilt angle of the mounting portion.

[0009]

In the above tilt type turntable (hereinafter, simply referred to as "turntable"), since the mounting portion provided on the upper portion of the table is tilted at a predetermined angle, the load lifted along the tilted surface is tilted. It can be placed on the placing part as it is. Then, when the table is moved on the pedestal, the movement of the table is restricted only by the rotation direction by the restriction member, so that the placed load can be turned to a desired direction.

When the restricting member provided on the pedestal is an axis fitted to a predetermined position of the table, the table can be rotated about the axis. For this reason, the cargo handling work can be easily performed without requiring a large amount of labor.

Further, by providing the angle adjusting means for adjusting the inclination angle of the mounting portion, the inclination angle of the mounting portion can be adjusted according to the angle of the inclined surface at the installation position of the turntable. Therefore, the range of application of the turntable can be expanded to easily carry out cargo handling work on any inclined surface.

EXAMPLE An example of the turntable will be described below with reference to the drawings. FIG. 1 is a side view illustrating the configuration of a turntable, FIG. 2 is a view illustrating an operation when carrying out a cargo handling work along stairs, and FIG. 3 is a view illustrating another example of a restriction member.

As shown in FIG. 1, the turntable A is
It is configured to have a table 1 and a pedestal 2, and the pedestal 2
The shaft 3 serving as a regulating member provided on the table 1 is fitted into a bearing portion (not shown) formed at the center of the lower surface of the table 1
The movement direction (movement direction) of is restricted only to the rotation direction.

The table 1 has a frame 1a which is formed with a preset inclined surface and an inclined portion having an angle substantially equal to the angle of the stairs and has a sufficiently high rigidity, and the inclination of the frame 1a. The mounting portion 4 is provided in the section. Further, a bearing portion is formed on the lower surface of the frame 1a, and a plurality of casters 5 serving as rotating bodies are arranged on the circumference centered on the bearing portion.

The pedestal 2 is composed of a plate 2a which is directly installed on an installation surface such as a floor surface or the ground, and a shaft 3 which is fixed to the plate 2a at substantially the center thereof. The plate 2
“A” is formed using a rigid material such as a steel plate so that the table 1 can rotate stably without being affected by the unevenness of the surface to be installed.

Turntable A constructed as described above
As shown in FIG. 2 (a), the placement section 4 is installed on an upper part of a slope such as a staircase or a sloping ground so as to be disposed on the extension of the slope. Then, a luggage C such as a building material is transported by the transport carriage B along the slope, and when the transport carriage B reaches the upper end of the slope, the transport carriage B is continuously run, so as shown in FIG. As described above, the carriage B can be placed on the placing section 4.

After the carriage B is mounted on the mounting portion 4, the table 1 is rotated in a desired direction to change the direction of the carriage B and the load C as shown in FIG. It is possible. In particular, as the carrier B for exclusive use of the inclined surface, for example, the car B provided with a crawler 8 suitable for climbing stairs, and further, the turntable A applied to the one configured to be self-propelled by a switch or the like. This facilitates getting on and off the mounting portion 4, which is preferable.

In the turntable A constructed as described above, since the placing portion 4 is formed to be inclined, it is preferable that the placed luggage and the like is prevented from slipping off. That is, it is preferable that the mounting portion 4 is made of a wood-based material, or a steel plate or the like is used to attach a wood-based material or a material having a large friction coefficient such as rubber to the surface. In this embodiment, the mounting portion 4 is made of a steel plate, and a rod-shaped steel material is welded to the surface of the steel plate to form the slip stopper 6.

The turntable A is used when carrying out cargo handling work, and its installation position is changed as the work progresses. For this reason, it is preferable that the table 1 and the pedestal 2 be detachable so that the turntable A can be easily transferred.

When the turntable A is relocated and used, there is no guarantee that the angles of the slopes on which the cargo handling work is performed are all constant, and the inclination angle of the mounting portion 4 is substantially the same as the angle of the slopes on which the cargo handling work is performed. Need to let. For this reason, in this embodiment, there is provided an angle adjusting means (not shown) for adjusting the mounting portion 4 in accordance with the inclination angle of the slope.

As the angle adjusting means, a known mechanism such as a mechanism using a hydraulic jack or a screw jack or a mechanism using a sector gear can be adopted.
For example, when a hydraulic jack is used, the mounting unit 4 is rotatably attached to the frame 1a, and the hydraulic jack is attached to a predetermined position of the frame 1a and connected to the mounting unit 4 to form an angle adjusting means. It is possible. Further, for example, the angle adjusting means can also be configured by fixing a semicircular sector gear to the lower surface of the mounting portion 4 and providing the frame 1a with a pinion that meshes with the sector gear.

Next, another example of the regulating member formed on the pedestal 2 will be described with reference to FIG. As shown in the figure, a circular restriction wall 7 is formed on the plate 2a forming the pedestal 2. The restriction wall 7 has a diameter corresponding to the diameter of the pitch circle of the caster 5 arranged on the lower surface of the table 1, and has a height that allows the caster 5 to be smoothly rotated and guided along the restriction wall 7. have.

Therefore, by placing the table 1 having the plurality of casters 5 on the lower surface on the pedestal 2 provided with the regulation wall 7, it is possible to easily rotate the table 1 in a desired direction.
