Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a cargo handling device for a flat body type freight vehicle.

[Prior Art] As shown in Fig. 1, in conventional devices of this kind, the table of the cargo handling device is also used as a rear tilter, so it is possible to load and unload light cargo without using the cargo handling device when loading and unloading flat-body cargo. Even when unloading, the cargo handling equipment must be activated to open the lift table, and since the lift table is stored upright, the rear view is obstructed by the lift table. I had to reduce the length. in this way,
In conventional systems, even when loading and unloading light loads that do not require the use of a cargo handling device, the cargo handling device must be operated to open the lift table, making the cargo handling operation complicated and time consuming. Furthermore, the lift table has a small length so that the rear view is not obstructed by the lift table, making it difficult to handle large loads.

On the other hand, Japanese Patent Publication No. 18525/1983 has proposed a van-type freight vehicle equipped with a lift device which is housed below the floor area and within its edge.
This is constructed so that the lift table is stored in a folded state under the floor and can be extended when in use, so the rear view is not obstructed by the lift table, and the long lift table can be extended out. It is possible to load and unload large loads. However, when such a lift device is installed on a flat-body truck with a rear tilt-up, the rear tilt-up will hang down to the edge of the floor when the loading/unloading port is opened when loading and unloading heavy loads that require a cargo-handling device. Therefore, when the lift table is extended to the use state and raised, the cargo handling device side collides with the hanging swing, making it impossible to raise and lower the lift table to the floor surface.

[Problems to be solved by the invention] In the above-mentioned conventional technology, when the former table is also used as a rear lift, the cargo handling device is operated to operate the lift table even when loading and unloading light cargoes that do not require the use of the cargo handling device. There were problems in that the cargo handling work had to be opened, which was complicated and time-consuming, and the length of the lift table was small, making it difficult to handle large cargo. To solve this problem, if the latter is equipped with a lifting device that is stored below the floor area and within its edge, it is possible to avoid loading and unloading heavy loads that require a material handling device. When the unloading port is opened, the rear swing hangs down to the edge of the floor, so when the lift table is extended to the operating state and raised, the cargo handling equipment side and the hanging swing collide with each other, causing the rear swing to hang down to the floor of the lift table. There was a problem that it was impossible to raise and lower the cargo, and it was not possible to use cargo handling equipment for heavy loads.

In order to solve this problem, it is possible to make the rear tilter have a double-door structure or a structure that allows it to be inserted and removed, so that when the rear tilter is open, the loading and unloading port can be opened without hanging down at the edge of the floor. However, in the case of a double-door structure, the horizontally long rear tilter must be opened to the left and right, making opening and closing operations cumbersome.In addition, since the horizontally long rear tilter extends to the left and right of the cargo platform, there is a risk of collision with people or obstacles. This is expected to be dangerous, and if the structure is such that it can be inserted and removed, it is expected that the cargo handling work will be hard work because it will be necessary to carry a heavy rear tilter each time cargo is handled.

Therefore, the object of the present invention is to provide a cargo handling device for a flat-body type freight vehicle that can be used as an underfloor storage type cargo handling device by simple and safe opening/closing and retracting operations of the rear tilter.

[Means for Solving the Problems] The present invention includes a rear tilt axis that is pivotally mounted to the floor end of a flat body type freight vehicle so as to be rotatable in the vertical direction, and a connection such as a magnet or a chain that fixes the rear tilt axis to the outer surface of the floor. an underfloor storage type cargo handling device is provided below the floor, and when the cargo handling device is stored under the floor, the rear tilter is rotated and opened using the pivot point as a fulcrum to load and unload a light load; Flat-body type cargo that is capable of loading and unloading heavy loads using the cargo handling device while the rear tilter is rotated to the outside of the floor using the pivot point as a fulcrum and fixed to the outside of the floor by the connecting member. This is an automobile cargo handling device.

[Function] The present invention opens the loading/unloading port by rotating and opening the rear tilter using the pivot point as a fulcrum while the cargo handling device is stored below the floor. With the cargo handling device lowered, the rear tilter is rotated around the pivot point to the outer surface of the floor, and the rear tilter is fixed to the outer surface of the floor by the connecting member, and then the cargo handling device is raised and lowered. In this case, since the rear tilter is stored under the floor, cargo handling can be carried out smoothly without any inconvenience caused by collision between the cargo handling device and the rear tilter when the lift table is raised or lowered.

[Example] An embodiment of the present invention will be described below.

As shown in FIGS. 2 to 4, a rear tilter 2 is pivotally attached to an end of a floor 5 of a flat body type freight vehicle so as to be rotatable in the vertical direction, and this rear tilter 2 is fixed to the outer surface side of the floor 5. It is configured to include a connecting member 6 such as a magnet or a chain, and an under-floor storage type cargo handling device 1.

FIG. 2A shows a state in which the under-floor storage type cargo handling device 1 is in a retracted state, the under-floor storage type rear tilter 2 is in a shielded state, and the vehicle can travel.

Figure 2B shows the rear tilt 2 from the state of Figure 2A.
The loading/unloading port is opened by rotating 180 degrees around the pivot point 8, and the loading/unloading port is opened, and the loading/unloading port is opened. In this case, the cargo handling device does not get in the way of opening the rear tilter 2.

FIG. 2C shows a state in which the rear tilter 2 is placed in a shielding state, the cargo handling device 1 is operated, and the arm 3 is brought into contact with the ground.

FIG. 2D shows that the lift table 4 is opened from the state shown in FIG. After the rear tilter 2 is stored under the floor in this way, heavy loads can be loaded and unloaded on the lift table 4 without being obstructed by the rear tilter 2. It shows the condition.

FIG. 3 is a rear view of the rear tilter 2 in a shielded state and the cargo handling device 1 in a state stored under the floor.The height of the rear tilter 2 is formed lower than the side tilter 7 so that the rear tilter 2 can be easily stored under the floor, and
The pivot portion 8 of the rear tilt 2 is extended a little longer. This is shown in more detail in the sectional view of FIG. 4 showing the operating state of the rear tilter 2. Further, the front part of the lift arm 3 is located between the pivot joints 8 of the rear tilter 2 when stored under the floor.

As described above, in the above embodiment, since the flat-body truck is independently equipped with the under-floor storage type rear tilter 2 and the under-floor storage type cargo handling device 1, it is possible to load and unload light loads that do not require a lift. It can be used in the same way as the flat body. In other words, by rotating the rear tilter 2 180 degrees around the pivot point 8 without being obstructed by the lift table 4, the rear tilter 2 can be hung down and opened, so there is no need to use a cargo handling device as in the past. This eliminates the disadvantage of having to operate the cargo handling device even when loading and unloading light loads, resulting in a cargo handling device with excellent workability. In addition, when loading and unloading heavy loads that require a lift, use the rear tilt 2.
is rotated 270 degrees around the pivot 8 as a fulcrum and is fixed to the outer surface of the floor 5 by a connecting member 6 such as a magnet, so that when the lift table 4 is raised, the hanging rear swing 2 collides with the cargo handling equipment 1 side. The lift table 4 can be raised and lowered without being obstructed by the rear tilter 2, resulting in a device with excellent cargo handling effects. Further, since the under-floor storage type cargo handling device 1 is used, a lift table 4 having a large length can be used, making it possible to load and unload large cargo.
Furthermore, when a double-door type rear tilter is used, opening and closing operations are troublesome, and there is a risk of having the horizontally long rear tilter protrude from side to side and rotating, but in the above embodiment, the rear tilter 2 is rotated in the vertical direction. Since it is fixed to the outer surface of the floor 5 via the connecting member 6, opening/closing and storing operations are easy, and it is highly safe because it does not protrude outward. In addition, if the structure is such that the rear tilt can be inserted and removed, the heavy rear tilt must be carried each time the rear tilt is opened or closed, which becomes a heavy labor.However, in the above embodiment, the outer tilt of the floor 5 can be easily moved by using the rotational moment due to the weight of the rear tilt. It is very easy to work because it can be fixed by rotating it to the side.

Note that the present invention is not limited to the above-mentioned embodiments, and various modifications can be made within the scope of the gist of the present invention.

[Effects of the invention] The present invention pivots a rear tilter to the floor end of a flat body type truck so that it can rotate in the vertical direction, and provides a connecting member such as a magnet or a chain to fix the rear tilter to the outer surface of the floor. An under-floor storage type cargo handling device is provided on one side of the cargo handling device, and when the cargo handling device is stored under the floor, the rear tilter is rotated and opened using the pivot point as a fulcrum to load and unload a light load, and the rear tilter is installed in the pivot point. This makes it possible to load and unload a heavy load using the cargo handling device while rotating it to the outside of the floor using the part as a fulcrum and fixing it to the outside of the floor using the connecting member. It is possible to provide a cargo handling device for a flat body type freight vehicle that can be used as an underfloor storage type cargo handling device by opening, closing, and retracting operations.
