Description

[Detailed description of the invention] [Purpose of the invention] (Field of industrial application) This invention is an elevator with a load transfer device used for loading relatively heavy items such as rice bales onto the loading platform of a freight car. Regarding.

(Prior Art) Various elevators have been devised so far for loading heavy objects onto a loading platform or the like. However, so-called simple elevators that are used for short periods of time require workers to unload the loaded cargo manually onto the loading platform.

(Problems to be solved by the invention) This invention was made in view of the conventional situation, and aims to provide a simple automatic load-transferring device that incorporates a load-transfer device into the load-lifting device. be.

[Structure of the invention] (Example) To explain the following with reference to the embodiment shown in the drawings, in Figs. Vertical fixed frame 2 and winch 3 with brake motor M
Equipped with.

The vertical fixed frame 2 is provided with a horizontal lifting frame 4 that moves up and down along the vertical fixed frame 2, and furthermore, a spring board whose tip end is pivoted to the horizontal lifting frame 4 is provided inside the horizontal lifting frame 4. A frame 5 is provided.

Reference numeral 6 denotes a lever rod, the center of which is pivotally supported 6c on the rear part of the horizontal lifting frame 4, with its active end 6a in contact with the lower surface of the tail of the platform frame 5, and the opposite end with a force end 6b. As the horizontal lifting frame 4 moves upward, the horizontal lifting frame 4 is brought into contact with an abutment member 12 vertically adjustable provided on a guide frame 11 vertically installed in parallel with the vertical fixed frame 2. When it rises above this level, the lever lever 6 is activated.

The lifting and lowering operation of the horizontal lifting frame 4 is performed using the winch 3 with the brake motor M as a power source, and the wire 8 is lowered via a pulley 9 attached to the upper part of the vertical fixed frame 2, and its tip is connected to the horizontal lifting and lowering. It is configured by being connected to the frame 4.

Although various means for vertically adjusting the middle abutment member 12 can be considered, in this embodiment, the movable cylinder 1 that is desired to be fixed to the guide frame 11 via the tightening screw 14 is used.
3 are fitted, and the abutting member 12 is shown protruding from the movable cylinder 13.

10 in the drawing is a forward/reverse operation switch for the motor M.

(Function) To use the automatic load transfer elevator according to the present invention, first, the truck body 1 is moved to face the loading platform of a freight vehicle stopped at a loading site.

Then, the abutting member 1 is adjusted according to the height of the loading platform.
2 up and down along the guide frame 11.

Next, the worker places the cargo on the horizontal lift frame 4 positioned at the lowest position.

Now, when the switch 10 is turned on, the horizontal lift frame 4 starts to rise along the vertical fixed frame 2, and the rise continues without any change until the lever lever 6 hits the abutment member 12. However, as it rises further, the force end 6b of the lever 6 hits the abutment member 12,
By further rising, the force end 6 of the lever 6
When b is pressed downward (the lever lever 6 rotates in a clockwise direction), the working end 6a of the opposite end pushes up the tail of the spring frame 5. That is, the spring frame 5 springs up using the pivot point at the tip as a base point (FIG. 3).

Then, the cargo on the inclined platform frame 5 naturally falls under its own weight and is loaded onto the platform.

[Effects of the Invention] As described above, the present invention does not merely raise the cargo, but also allows it to automatically fall naturally from the rising point to the loading platform, so it can significantly reduce the labor of workers on the loading platform. Furthermore, since the natural fall point can be adjusted arbitrarily, it can be adapted to various heights of the loading platform, which is very convenient for work.
