As shown in (b), a short shaft (8) projecting outward is fixed.

On the other hand, the left and right side plates (3) of the loading platform (1),
Brackets (9) are respectively protruded at positions facing the arms (7) on the upper surface of (3), and a short cylindrical shape is formed inside the bracket (9), as shown in FIG. A groove which forms a frame receiving hole (10) and which extends from one side of the outer surface of the bracket (9) in the radial direction of the frame receiving hole (10) to the axis of the frame receiving hole (10). A split groove (1) having a groove width in which the shaft (8) can be inserted and removed.
1) is formed, and a slot (13) having the same groove width as the above-mentioned split groove (11) is formed in the frame receiving hole (10), particularly as shown in FIG. Locking top (12)
Are rotatably fitted to each other so that the locking piece (12)
Is rotated to align the split groove (13) with the split groove (11) of the bracket (9), the shaft (8) of the partition plate (6) is set in the split grooves (11) and (13). Can be inserted into the bracket shaft center position through the
2), the split groove (13) is shifted by 90 degrees with respect to the other split groove (11), and the shaft (8) is shifted to the bracket axis position as shown in FIG. Will be retained.

On the outer peripheral surface of the locking piece (12), a turning operation handle (14) is fixed at a base end of the handle so that the turning operation handle (14) is directed in a direction substantially perpendicular to the split groove (13). 14) is projected from the split groove (11) to the outside, and a 90 ° turning operation of the handle (14) is allowed on a peripheral wall surrounding the frame receiving hole (10).
A guide groove (15) extending 90 degrees upward from the split groove (11) is provided. In this example, the handle (1
When 4) is swung to the upper end point along the guide groove (15), the split grooves (11) and (13) coincide.

Next, means for locking the partition plate (1) so as not to swing will be described. As shown in FIG. 2, a receiving metal fitting (16) having a pin locking hole (17) is provided below the left and right sides of the partition plate (6). 3), while the partition plate (6) is positioned vertically on the outer side surfaces of the left and right side plates (3) and (3) with respect to the carrier bottom plate (2). A lock pin device (18) is provided at a position facing the receiving bracket (16).

The lock pin device (18) is as follows. In FIG. 5, holes (1) provided in the side plate (3) are shown.
9) fix the cylinder (20) with the opening at the tip on the outer surface,
The lock pin (21) is slidably inserted into the cylinder (20), and the hole (1) of the side plate (3) is inserted from the tip of the cylinder (20).
9) is inserted so as to be able to advance and retreat inside the carrier, and a rod (22) concentrically connected to the rear end of the lock pin (21) is protruded outside from the rear end of the cylinder (20). A rectangular frame-shaped handle (23) is fixed, and a spring (24) is wound around the rod (22) thus formed. The lock pin (21) is always held by the spring (24) as shown in FIG. Metal fittings like (16)
When the handle (23) is pulled rearward, the lock pin (21) can be detached from the receiving fitting (16) as shown in FIG. It is configured to retreat to the position.

As means for holding the lock pin (21) in a detached state, two locking plates (2) having a locking recess (26) at the rear end thereof are provided on the rear end surface of the cylinder (20).
5) and (25) are protruded parallel to each other on both sides of the handle (23), whereby the handle (23) is pulled backward, and then rotated 90 degrees to make the double-stop plates (25) and (2).
5) Orientation in the direction perpendicular to
When 3) is locked in the locking recesses (26), (26), the lock pin (21) is held at the retracted position.

In FIGS. 1 and 2, (27) indicates a position where the partition plate (6) is perpendicular to the carrier bottom plate (2), that is, a position where the lock pin (21) faces the receiving bracket (16). A stopper that abuts the left and right sides of the partition plate (6) so as not to swing forward any more when it swings, and protrudes from the left and right side plates (3) and (3).

The operation of the above example will now be described. Partition plate (6)
The shaft (8) is supported by the bracket (9), the lock pin (21) is locked in the locking hole (17) of the metal fitting (16), and the partition plate (6) is perpendicular to the bottom plate (2). In the state where the inside of the loading platform (1) is divided into two front and rear compartments, two kinds of loads, for example, gravel and sand are loaded in both compartments in a separated state. The dump truck is driven to the destination, the back side plate (5) of the loading platform (1) is opened at a predetermined location, and the loading platform (1) is tilted forward and upward by tilting drive, thereby sliding down the load in the rear compartment. In the meantime, the load in the front compartment is locked by the lock pin (21) so as not to be able to swing.
And is held in the carrier. next,
The dump truck is moved to the next predetermined place, where the handle (23) is pulled to receive the lock pin (21) and the metal fitting (1).
When disengaged from 6), the load in the front section slides down under the partition plate (6) while swinging the partition plate (6) backward about the axis (8) by its own weight. .

When changing to normal loading instead of sorting and loading, first, the handle (23) is pulled to separate the lock pin (21) from the receiving fitting (16), and then the handle (23) is turned 90 degrees. Turn and lock plate (25), (25)
In the locking recesses (26), (26), thereby holding the lock pin (21) in the unlocked state. Next, the handle (14) of the bracket (9) is moved to the position shown in FIG.
Is pivoted upward by 90 degrees so that the split groove (13) of the locking piece (12) is aligned with the split groove (11) of the frame receiving hole (10). The axis (8) of the partition plate (6) is disengaged from the bracket (9) along (11) and (11), and the entire partition plate (6) is removed from the carrier (1).

When the partition plate (6) is reused, the partition plate (6) is carried into the carrier (1), and its shaft (8) is
Insert the grooves (11) and (13) matched as described above into the grooves (11) and (13), and turn the handle (14) downward by 90 degrees so that the groove (13) of the locking piece (12) is divided into the other. 90 ° offset with respect to the groove (11), so that the shaft (8)
Is rotatably held on the axis of the bracket (9).

[0016]

According to the partitioning device of the inclined drive type carrier in the freight car of the present invention, the partition plate is pivotally supported in the carrier so as to be able to swing back and forth, and is locked so as not to swing, so that the inside of the carrier can be moved forward and backward. It is possible to load multiple types of loads in a separate state by dividing them into sections, and in loading / unloading, lowering the load in the rearmost section by tilting the loading platform, and then unlocking the partition plate sequentially, It is possible to sequentially load and unload the load in the front compartment of the above, thereby loading and unloading a plurality of types of loads in a sorted state, and by separating and separating the partition plate from the left and right side plates of the loading platform,
The platform can be returned for normal loading, which is extremely convenient for use.
