Abstract

PURPOSE:To facilitate the loading and unloading of cargos onto and from a cargo bed, by swingably supporting the cargo bed having a roller conveyor on its top surface, on a vehicle body, and by enabling the cargo bed to be inclined down forward and rearward by means of a control device. CONSTITUTION:Upon cargo loading an elevator 18 is raised to its uppermost position by means of a motor 20 while a cargo bed 3 is inclined down forward by rotating a handle 9 of a control device 8. Then, a cargo is loaded on a cargo receiving bed 15 which is then raised up to the level of the cargo bed 3 by means of a motor 16. Next, the cargo on the cargo receiving bed 15 is shifted onto the cargo bed 3, and is moved forward since the cargo bed 3 is inclined. When the cargo bed 3 is fully loaded, the elevator 18 is lowered until it abuts against the cargo on the cargo bed 3, and therefore, the cargo is held by the elevator 18. Further, the cargo receiving bed 15 is again raised up to the elevator 18, and therefore, the cargo on the cargo receiving bed 15 may be loaded on the elevator 18.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Use The present invention is used in the field of freight vehicles that facilitate the loading and unloading of cargo.

(b) Prior Art Conventional freight vehicles are provided with a roller conveyor on the floor to facilitate the movement of cargo on the loading platform.

However, since roller conveyors are installed horizontally, it requires a lot of effort to handle large loads.
In addition, if the loading area is sloped slightly backwards, there is a drawback that a large amount of manual effort is required to push the loading area.

(C) Problems to be Solved by the Invention The present invention solves the above-mentioned drawbacks by supporting a loading platform having a roller conveyor in a swingable manner on the vehicle body, and using a control device to move the loading platform forward and backward or backward. It is designed so that it can be tilted downward.

(dl Means for Solving the Problems) The present invention provides a freight vehicle which is provided with a loading platform on a vehicle body, a body that covers the loading platform, and a luggage loading device at the rear end of the body. The present invention relates to a freight vehicle which is provided with a roller conveyor, has a loading platform hinged to the vehicle body in a swingable manner, and is provided with a control device between the loading platform and the vehicle body that allows the loading platform to be moved forward or backward or backward.

telExampleThe following example will be explained using the drawings. (1) is a truck, and the truck (1) has a loading platform (3) on the vehicle body (2) and a box-shaped box that covers the loading platform (3). A body (4) is provided, and a cargo platform (3) is provided at the rear end of the body (4).
) is provided with a loading device (5).

A roller conveyor (6) is provided on the upper surface of the loading platform (3) in the front-rear direction. Further, the lower center portion of the loading platform (3) is swingably supported by a hinge (7) of the vehicle body (2).

(8) is a control device installed at the rear of the vehicle body (2), and by turning the handle (9) of the control device (8), the screw shaft αe is raised and lowered, and the loading platform (3) is moved forward and downward or backward. It is designed so that it can be tilted.

(11) (12) are the front support stand and rear support stand attached to the vehicle body (2), both support stands (11) (12)
is adapted to prevent the loading platform (3) from swinging beyond a predetermined level and to support the loading platform (3) in an inclined state.

The loading device (5) has a guide frame (1) at the rear end of the body (4).
3) Set up one pair of (13) and insert this guide frame (13)
(13) An elevating member (14) is provided in between so as to be movable up and down;
A loading platform (15) is held horizontally at the lower end of the lifting member (14), and a loading platform motor (
16), the lifting member (14) is raised and lowered via a wire (17).

(18) is a lifting platform provided above the loading platform (3), and a roller conveyor (19) is provided on the upper surface of the lifting platform (18). It is raised and lowered via a wire (21) by a lift motor (20) provided.

In addition, the hinge position of the loading platform is not limited to the center;
As long as the loading platform is in a position where it can swing, it will be satisfactory.

The present invention has the above-mentioned configuration, and its operation will be explained next. First, when loading cargo, the lifting platform (18) is raised to the highest position (solid line position) using the lifting platform motor (20). Then, turn the handle (9) of the control device (8) to lower the loading platform (3) forward.

In this state, place the luggage on the loading platform (15) and place it on the loading platform (15).
) is raised to the loading platform (3) by the loading platform motor (16), and when the loading platform (15) is aligned with the loading platform (3), the lifting of the loading platform (15) is stopped, and the loading platform (15) is raised to the loading platform (15). Move the upper baggage onto the loading platform (3).

The luggage moved onto the loading platform (3) can be moved forward with little effort since the loading platform (3) is inclined forward and downward.

By repeating the above operations, when the cargo platform (3) is full, the platform motor (20) lifts the platform (18).
is lowered until it touches the cargo on the loading platform (3), and the lifting platform (18) is supported by the cargo.

Thereafter, the goods can be loaded onto the lifting platform (18) by raising and lowering the loading platform (15) to the lifting platform (18) using the loading platform motor (16).

When unloading the cargo, turn the handle (9) of the control device (8) in the opposite direction to tilt the cargo platform (3) backward.

In this state, the cargo can be unloaded with little effort by repeating the reverse operation of loading.

(fl) Effects of the Invention As described above, the present invention makes the loading platform provided on the vehicle body swingable and allows the loading platform to be tilted forward or backward, making loading and unloading work with little effort. Furthermore, even when working on a slope, the work can be done with little effort by swinging the loading platform to match the slope.

[Brief explanation of the drawing]

FIG. 1 is an overall view of the present invention. (2) is the vehicle body, (3) is the loading platform, (5) is the loading device, (8
) is a control device.

Claims (1)
